　　CCTV News:South Korean Presidential Palace Cheongwadae announced on the 8th that Moon Jae in will meet with a visiting high-level delegation from the DPRK on the 10th. Members of the delegation include Jin Yongnan, Chairman of the Standing Committee of the Supreme People’s Assembly of the DPRK, Jin Yuzheng, First Deputy Minister of the Central Committee of the Workers’ Party of Korea, Cui Hui, Chairman of the State Sports Steering Committee, and Li Shanquan, Chairman of the Peaceful Reunification Committee of the Motherland. According to Xinhua News Agency, the DPRK delegation arrived at Incheon Airport in South Korea by special plane at noon on the 9th.

　　Who’s Jin Yuzheng? What is the future trend of the situation on the peninsula? Will the representatives of North Korea, South Korea and the United States interact outside of sports events? The PyeongChang Winter Olympics in 2018 was full of topics before it started.

　　Rare! Kim Jong-un once only took his twin sister to inspect the troops.

　　Jin Yuzheng is the daughter of the late North Korean leader Kim Jong Il and the younger sister of Kim Jong Un.

　　On March 9, 2014, Jin Yuzheng made her first "official appearance" in a report on North Korean national television. At that time, Kim Jong-un was elected as the representative of Baitoushan Constituency No.111 with 100% support rate. Jin Yuzheng, known as "Comrade", appeared for the first time in the report, and a "close-up" of her voting was shown.

　　On November 27th, 2014, Kim Jong-un inspected the 426 Animation Studio. Korean Central News Agency mentioned Jin Yuzheng, Vice Minister of the Central Committee of the Labor Party, when introducing the accompanying personnel. This was the first time that the North Korean media publicized Jin Yuzheng’s position, which attracted the attention of foreign media.

　　After that, Jin Yuzheng can always be seen in Kim Jong-un’s activities reported by North Korea’s official media. From watching performances, to inspecting factories and museums, to inspecting military training activities, Jin Yuzheng’s name can always be found in the list of accompanying persons.

　　From March 9, 2014 to March 12, 2015, Jin Yuzheng accompanied Kim Jong-un on 25 inspections. Since November, 2014, Jin Yuzheng has been accompanying Kim Jong-un to inspect more and more frequently, accounting for more than half of the total times. Generally speaking, Jin Yuzheng’s people’s livelihood and cultural performances are twice as many as her military and political visits. However, since November 2014, her visits to the army have been basically the same as other activities. In January 2015, Jin Yuzheng’s public activities were particularly active, and he accompanied Kim Jong-un on seven inspections.

　　On March 12, 2015, Kim Jong-un, the top leader of North Korea, visited a defense squadron in the front post on the east coast of North Korea. In Korean Central News Agency’s report, only the name of Kim Jong-un’s sister Jin Yuzheng was mentioned, but the names of other accompanying persons were not mentioned. Judging from the pictures released by the Workers’ Party of Korea, Jin Yuzheng not only accompanied Kim Jong-un to inspect the whole process, but also participated in the final photo. This kind of situation is rare. Usually, the entourage of Kim Jong-un does not take part in the group photo during the inspection activities, and it is the first time that only Kim Jong-un’s brother and sister inspect the troops in the official media of North Korea.

　　At present, it is a critical moment for the DPRK and the ROK to release goodwill and improve bilateral relations. Kim Jong-un sent Jin Yuzheng to represent North Korea in the opening ceremony of the PyeongChang Winter Olympics, and the position of the younger sister in North Korea’s political arena is self-evident.

　　The South Korean side also attaches great importance to the first entry of North Korean Kim family members into Korea. A spokesman for South Korea’s Cheongwadae said that all preparations would be made to ensure the smooth visit of the DPRK high-level delegation to South Korea to participate in the Olympic Games, and called Jin Yuzheng’s visit "of great significance". As Jin Yuzheng is an important figure in the Labor Party, the ROK expects that she will have considerable discretion in this trip, which is more important than Jin Yongnan’s coming to hankyung alone, and the ROK and the DPRK may take this opportunity to have a more meaningful dialogue.

　　The close interaction between the DPRK and the ROK, the United States and Japan secretly "make bad"

　　The 23rd Winter Olympics in Pyeongchang, South Korea in 2018 is destined to be an "unusual" Winter Olympics. Before that, the Vice President of the United States invited "special guests" to pour cold water on the relations between the DPRK and the ROK, and then members of the North Korean "Baitoushan family" (Kim family) entered Korea for the first time. During this period, it was reported that Trump’s daughter would attend the closing ceremony of the Winter Olympics and the South Korean Unification Ministry made intensive statements four times in three days … … The "feature film" of the 2018 Winter Olympics has not yet started, and the "trailer" alone is as wonderful as any Hollywood movie.

　　At the beginning of the new year in 2018, the DPRK and the ROK changed the normal state of "arrogance" and "angry words", shelved the dispute between nuclear weapons and Sadr, and launched active "ice-breaking" talks around the Winter Olympics in a "double pause" posture, which achieved many results. For example, the DPRK and the ROK will jointly hold the flag of the Korean Peninsula at the opening ceremony of the Winter Olympics, the Korean art troupe will perform the opening ceremony in South Korea, and the DPRK and the ROK have expressed their positive will to improve the bilateral relations in the future … …

　　At the same time of close interaction between the DPRK and the ROK, the United States began to "pour cold water" on the slowly warming DPRK-ROK relations.

　　US President Donald Trump confirmed last month that he would send Vice President Burns as the head of the US delegation to attend the PyeongChang Winter Olympics. However, it is not known what attitude Burns will take to intervene in the situation on the Korean Peninsula. A White House official said that Burns believed that the DPRK wanted to use the Winter Olympics to "engage in propaganda activities" and he intended to "show up" at the Winter Olympics to "offset" the DPRK’s influence and self-promotion efforts.

　　According to Washington post, Burns will invite a "special guest", namely Fred, the father of the late American college student Otto Warmbier, to visit Korea. Otto Warmbier was charged and convicted of conspiring to subvert the state in North Korea, and was detained for more than a year. He was released to China in June last year, but he was in a coma and died a few days later. This incident once prompted the State Council to issue a travel ban to the DPRK.

　　It is also reported that US President Trump’s daughter ivanka will lead a presidential delegation to attend the closing ceremony of the 2018 PyeongChang Winter Olympics. Some South Korean media analysts said that if ivanka really attended the closing ceremony of PyeongChang Winter Olympics as reported by CNN, and Kim Jong-un’s younger sister Jin Yuzheng also went south for a pre-meeting, it might be possible for them to meet in the closing ceremony of Winter Olympics.

　　The DPRK, the United States and South Korea are playing hot, and Japan is also joining in the fun. According to the news released by the Japanese government on the 3rd, Prime Minister Shinzo Abe will meet with Burns before attending the opening ceremony of the Winter Olympics, suggesting that the US-South Korea joint military exercise should not be scaled down after the Winter Olympics.

　　… …

　　The Korean Peninsula crisis has lasted for more than 20 years, and the biggest obstacle is the "return to Asia-Pacific strategy" of the United States. However, this "door-to-door talk" between the DPRK and the ROK is a sincere attempt by the DPRK. It is hoped that with the efforts of all parties, the stability of the DPRK and the ROK will be further developed, and the rare "warm drama" between the DPRK and the ROK will not become a "farce" with no end in some countries.

　　In August, the temperature rises, the rainfall increases, and the humid and hot weather is conducive to the growth and reproduction of microorganisms and vectors, causing the spread of many infectious diseases.

　　Experts from Henan CDC hereby remind residents to focus on hand-foot-mouth disease, fever with thrombocytopenia syndrome, brucellosis, novel coronavirus infection, monkeypox and food poisoning this month. In addition, special attention should be paid to the prevention of extreme weather events and accidental injuries of children and adolescents during summer vacation.

　　Key tips

　　First, hand, foot and mouth disease

　　Hand, foot and mouth disease (HFMD) is a common infectious disease in children, which is caused by various enterovirus infections. Children under 5 years old are more likely to be infected through close contact, respiratory droplets and digestive tract. Recently, the incidence of hand, foot and mouth disease in our province has decreased, but it is still at a high level, exceeding the level of the same period in the past two years. We should pay attention to the health status of young children, maintain good personal hygiene habits, and regularly clean and disinfect the family and the surrounding environment.

　　Protective measures:

　　1. Pay attention to personal hygiene, especially hand hygiene. Wash your hands with clean water, hand sanitizer or soap before touching your mouth and nose, before eating and defecating, before processing food, after touching herpes/respiratory secretions, after changing diapers or handling items contaminated by feces; Cover your nose and mouth with a handkerchief or paper towel when sneezing or coughing, then wrap the paper towel and throw it into the covered trash can.

　　2. Do not share towels or other personal items with others; Do not contact patients and their contaminated articles, and pollute the environment; Do not swim or play in the unsterilized swimming pool. During the epidemic of hand, foot and mouth disease, try to avoid taking children to participate in group activities.

　　3. Always clean and disinfect the surfaces of articles or objects that are often in contact, such as toys and furniture. After cleaning, wipe them with chlorine-containing disinfectant or soak them for disinfection. After 30 minutes, wipe them with clean water or rinse them off.

　　Second, fever with thrombocytopenia syndrome

　　Fever with thrombocytopenia syndrome is a new infectious disease caused by a new Bunia virus, which is spread by tick bites. The rain increases in August, and the high temperature and humid environment is suitable for the growth and reproduction of ticks. When you are active in parks, fields and other places with dense vegetation, you should be well protected to prevent ticks from biting.

　　Protective measures:

　　1. Personal protection should be done during outdoor activities, such as wearing long-sleeved underwear, tightening trouser legs, and applying repellent to bare skin, so as to avoid sitting and lying for a long time in the main habitats of ticks, such as grass and Woods, and prevent ticks from biting. Don’t pull hard after being bitten by a tick, spray it with alcohol and then clamp the tick head with pointed tweezers to peel off slowly.

　　2. Management of infected persons. In general, it is not necessary to isolate patients. Medical staff and patients’ families in medical institutions should do personal protection when caring for patients, and the patients’ blood, secretions, excreta and the environment and articles polluted by them can be disinfected by means of high temperature, high pressure and chlorine-containing disinfectant.

　　Third, brucellosis

　　Brucellosis (brucellosis) is a zoonotic disease caused by Brucella. The main clinical manifestations are fever, hyperhidrosis, joint pain and so on. Sheep are the main source of infection. People in pastoral areas, aquaculture and other occupations can be infected through skin and mucous membrane contact during slaughter, peeling and milking. Eating undercooked meat, drinking raw milk or inhaling contaminated droplets can also lead to brucellosis. In recent years, brucellosis has also occurred from time to time in non-pastoral areas, so we should pay attention to self-protection.

　　Protective measures:

　　1, sheep breeding, grazing, trading, slaughtering and other professional people should pay attention to daily personal protection, timely medical treatment after illness.

　　2. Try to avoid direct contact with any animals, especially those of unknown origin.

　　3. Do not eat undercooked meat, eggs, milk and other animal products. Choose fresh and safe animal food raw materials, and pay attention to the separation of raw and cooked food when processing.

　　Fourth, monkeypox

　　Monkeypox is a zoonotic disease caused by monkeypox virus infection, and its clinical manifestations are mainly fever, rash and lymphadenopathy. In the past, it mainly occurred in Central Africa and West Africa. Since 2022, monkeypox outbreaks have occurred in many non-endemic areas around the world, with a mortality rate of about 0.1%. Most cases have mild clinical manifestations, and the deaths are mainly people with low immunity such as untreated HIV-infected people. Since June 2023, many provinces in China have reported many cases of monkeypox, most of which are young and middle-aged men, mainly transmitted through sexual contact. Men who have sex with men are the key groups infected with monkeypox. People are generally susceptible to monkeypox virus, and smallpox vaccine has a certain degree of cross-protection against monkeypox virus.

　　Protective measures:

　　1. Entry-exit personnel should pay attention to the epidemic information of monkeypox in destination countries and regions, and avoid contact with monkeypox-like symptoms, rodents, primates and other animals.

　　2. Returnees who have a history of suspicious contact abroad should do a good job in self-health monitoring to avoid close contact with others. In case of monkeypox-like symptoms such as fever, rash and lymphadenopathy, they should take the initiative to see a doctor and truthfully report their epidemiological history.

　　3. Key people need to raise awareness of prevention and reduce high-risk behaviors. If they have a history of suspicious contact, they should consciously monitor their health and take the initiative to see a doctor if symptoms appear.

　　V. novel coronavirus infection

　　Recently, the number of people infected in novel coronavirus in our province has shown a downward trend. The elderly, key people with basic diseases and low immunity still need to adhere to personal protection and actively vaccinate. Those who have not completed basic immunization and are not infected with Covid-19 should complete basic immunization first.

　　Protective measures:

　　1. Actively vaccinate. Elderly people aged 60 and above, people aged 18-59 with serious basic diseases, people with low immune function, people with high risk of infection, and people who have completed basic immunization or have been infected with Covid-19 should be actively vaccinated to further strengthen their autoimmune ability.

　　2. Pay attention to personal protection. Residents should wear masks in their daily trips, minimize unnecessary gatherings and keep social distance. Maintain good personal and environmental hygiene, wash hands frequently, often ventilate, pay attention to rest, pay attention to nutrition and enhance physical fitness.

　　3. Use drugs rationally and see a doctor as needed. After infection, residents should take corresponding treatment measures according to the severity of their own symptoms, implement self-care at home, reduce contact with their roommates, rationally use symptomatic drugs according to relevant guidelines, do a good job in health monitoring, and go to medical institutions in time if the condition worsens.

　　Six, food poisoning

　　In August, the temperature is high and the humidity is high, and food is perishable. Improper food processing or storage can easily lead to food poisoning. Recently, food poisoning incidents have occurred frequently in many parts of the country. People must pay attention to food hygiene when eating at home or out. When they have symptoms such as nausea, vomiting, abdominal pain and diarrhea, they should induce vomiting as soon as possible to reduce the absorption of toxins and send them to the hospital for treatment in time.

　　Protective measures:

　　1. Avoid eating in public places without health protection. Buy food in supermarkets or vegetable markets with health protection. Try not to buy bulk food.

　　2. Fresh food should be fully heated before eating, and attention should be paid to the cleanliness of processed cold and raw foods. Avoid mixing raw and cooked food, mixing chopping boards and kitchen knives, and prevent cross-contamination of raw and cooked food. Try not to leave any food in each meal. Don’t store the leftover food in the refrigerator for too long. It must be heated thoroughly before eating.

　　3. Develop good personal hygiene habits, wash your hands before and after meals and before processing food.

　　VII. Extreme weather events

　　With global warming, extreme weather events occur frequently. Typhoon No.5 "Du Surui" landed in Fujian on July 28, and the residual circulation went all the way north, resulting in large-scale heavy rainfall in Henan, Shandong, Beijing-Tianjin-Hebei and Liaoning, with heavy rain in the local area. Recently, there have been heavy rains in many places in our province, and heavy rains have occurred in some counties and cities, accompanied by complex strong convective weather. At present, the impact of Typhoon Du Surui on Henan Province has ended, but it is still rainy in our province in the near future due to the strengthening of the westward extension of the subtropical high, the uplift of typhoon Kanu and the windward slope in mountainous areas.

　　At present, it is in the critical period of "seven downs and eight highs" (from late July to early August). Due to the influence of typhoon and subtropical high, our province will usher in the humid and sultry weather of "rainfall+high temperature". The public should pay close attention to the warning signals of meteorological disasters, respond in time, and do a good job in heatstroke prevention and cooling.

　　Eight, children and adolescents accidental injury

　　Summer vacation is a period of high incidence of accidental injuries among children and adolescents. While celebrating the holiday, special attention should be paid to preventing accidental injuries such as drowning, traffic accidents, falls, poisoning, burns, electric shock, airway foreign bodies, and animal bites.

　　Protective measures:

　　1. Parents should carry out safety inspection on daily necessities at home, so as to eliminate those foreseeable and avoidable safety hazards, such as hot water bottles, hot water cups and kitchen utensils with hot soup, which should be placed out of children’s reach; Household electrical equipment and power supply should be kept away from children’s reach; Take good care of household chemicals, and it is best to store medicines in safe packages that prevent children from opening them.

　　2. In terms of children’s diet and daily life, it should be fresh and non-toxic to prevent food pollution and deterioration. Teach children not to run or cry when eating, and correct the bad habits of children’s mouth contents.

　　3. Never leave children alone by the open water source. No matter in the water at home, indoors, outdoors or other places, the distance between parents and children should be within reach and concentrate on nursing. Parents must educate their children not to swim in dangerous waters/water bodies or informal swimming pools to prevent drowning. If you encounter a drowning companion, don’t rescue yourself by force. You should shout for help and ask people around you to help you.

　　4. Pay attention to cultivate children’s safety awareness, guide children to obey traffic rules, don’t chase and fight on the side of the road, and sit in the child safety seat and fasten the seat belt when traveling by car.

　　Fill in the shortcomings of popular science and improve citizens’ scientific quality ②

　　Encouragement is necessary, but it is more important to make researchers feel that it is beneficial to do it from the heart. At the same time, the scientific community will recognize the behavior of this profession and will not think that scientific researchers are "doing nothing" when doing popular science.

　　Zhonghe Zhou

　　Academician of China Academy of Sciences and researcher of vertebrate paleontology and Paleoanthropology Institute of Chinese Academy of Sciences.

　　"We just want to open a video number and do two short videos about big health and food safety every week, but after talking to a professional shooting and production team, one will cost one or two thousand, and this funding has not yet been settled." After taking office last year, Shen Qi, director of the Institute of Agricultural Products Processing of Jiangsu Academy of Agricultural Sciences, first thought was to promote popular science knowledge of food health to the public.

　　However, it is too difficult for this wish to land. "In addition to funding, the opening of WeChat official account has to be approved at different levels, and an interested scientific researcher has to be responsible for it." Shen Qi said that the recent statements of the central ministries and commissions calling for strengthening popular science work have given him hope. He said: "Maybe there will be funds to build WeChat official account next year."

　　Scientific researchers are considered as "the first starter of scientific communication", and it should be one of their duties to do a good job in popular science. However, for a long time, the proportion of scientific researchers involved in popular science is not high, and the atmosphere of popularizing scientific knowledge to the public has not become popular in scientific research circles. What is the reason for this? Is it a lack of system or a lack of funds? Some researchers’ answers may provide a basis for relevant state departments to formulate policies.

　　People who are most suitable for science popularization can’t let go of their hands and feet

　　Yongchun Zheng, a researcher at the National Astronomical Observatory of the Chinese Academy of Sciences, is now the "online celebrity" in the field of popular science.

　　"I didn’t take the initiative to enter this field, just like when I chose my major before. I didn’t take the initiative to choose, but I didn’t resist it when I had such an opportunity. I was willing to understand it, and I slowly entered through this process." In 2015, an accidental teaching experience brought Yongchun Zheng into contact with the writing of popular science articles, and he became a popular science expert step by step. "After publishing a book, he later registered a blog and had more opportunities to do more things, thus opening up a whole new world."

　　Today, when China has become a strong voice of the times, there are few "online celebrity" scientists like Yongchun Zheng, and it is still controversial whether popular science is the responsibility of researchers.

　　In recent years, a number of investigations and analyses on the participation of scientific researchers in popular science have drawn similar conclusions — — High recognition, strong will and weak mobility. Why can’t researchers who are most suitable for popular science let go?

　　Researcher Wang Yongdong, director of the Science Communication Center of Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, told the reporter that there are two main reasons why researchers are absent from popular science work: first, objectively speaking, popular science takes up the time and energy of researchers, but it doesn’t count in the assessment, such as awarding prizes, evaluating professional titles, and there is neither corresponding post setting nor corresponding incentive mechanism. After all, in scientific research units, everyone pays more attention to projects, papers, impact factors, talent hats, etc.

　　Secondly, subjectively speaking, most researchers feel that science popularization work does not need too deep professional knowledge; At the same time, I am worried that science popularization needs to use the achievements of others, resulting in intellectual property disputes. I feel that it is better to concentrate on writing my own paper than to spend time doing unfamiliar science popularization work.

　　The researchers interviewed agreed that in the current scientific research and talent evaluation system, most of the popular science contributions are nameless, unprofitable and thankless. Under the guidance of such a "baton", the collective cognition of attaching importance to scientific research and neglecting popular science has gradually formed.

　　"On the cultural level, although there is only one word difference between scientific research and popular science, they are completely different. The scientific research culture is inward, and it pursues recognition in academic circles and professional circles. The culture of popular science is extroverted, and it pursues public recognition." Yongchun Zheng said.

　　Scientific researchers can’t do "one size fits all" in doing popular science.

　　Since the existing "baton" ignores popular science, will the enthusiasm of researchers be high if the contribution of popular science is increased in the scientific research evaluation system?

　　The reporter learned that in recent years, the state has introduced relevant policies to encourage popular science. For example, "Several Opinions on Opening Scientific Research Institutions and Universities to the Society to Carry out Popular Science Activities" clearly puts forward the suggestion that the performance evaluation method of scientific communication should be regarded as an important basis for the evaluation of scientific researchers’ professional titles and post appointment. However, there are no substantive operating rules and hard rules, which leads to the failure to implement the policy.

　　In the interview, the reporter also found that researchers have different opinions on the proposal of establishing a rigid system for popular science assessment.

　　"I used to think that researchers should be encouraged to do popular science, or some institutionalized incentive mechanisms should be established, but now I feel more and more that we can’t generalize." Yongchun Zheng said that the main business of scientific researchers is scientific research. Doing popular science not only requires scientific research background, wide knowledge and willingness to share, but also takes a lot of time and energy to accumulate experience, which is not suitable for everyone.

　　Zhou Zhonghe, an academician of the China Academy of Sciences and a researcher at the Institute of vertebrate paleontology and Paleoanthropology of the Chinese Academy of Sciences, once said at the 27th National Symposium on Science Popularization Theory that administration is a double-edged sword, and it is impossible to make a one-size-fits-all policy. For example, science popularization should be regarded as the assessment index for all scientific researchers.

　　Shen Qi suggested that a research group, a laboratory and a research institute can be quantitatively assessed, forcing the heads of teams and units to pay attention to popular science work.

　　Zhou Zhonghe said, encouragement is necessary, but it is more important to make researchers feel that it is beneficial to do it from the heart. At the same time, the scientific community will recognize the behavior of this profession and will not think that scientific researchers are "doing nothing" when doing popular science.

　　Luo Jingjia, dean of the Frontier Research Institute of Climate and Application in Nanjing University of Information Science & Technology, has been working abroad for a long time. He told reporters that foreign scientists are very happy to share their scientific research progress and related scientific knowledge. "Isn’t writing papers a kind of popular science? It’s just a popular science for professionals. Since you can share it with insiders, why don’t you bother to spread science to the public? "

　　Luo Jingjia said that different languages need to be translated, and different disciplines are interlaced like mountains. Scientists in other fields are also members of the public and need popular science. Once this kind of cognitive and popular science culture is formed, there is no need for a system to make it hard.

　　The system of popular science should be established as soon as possible.

　　Lack of funds for popular science is the most common voice heard by reporters in interviews. So, do scientific research units have special funds for popular science work?

　　Among the 120 research institutes of Nanjing Institute of Geology and Paleontology, China Academy of Sciences, the scientific communication index is in the forefront. It is said that the institute should invest a lot in people and property to achieve such achievements. Wang Yongdong told reporters that the institute is very supportive of science communication, and the budget of the Science Communication Center alone this year has reached nearly 7.8 million yuan. Expenditure expenses include editing and publishing expenses of several professional magazines, purchasing expenses of library documents and materials, specimen maintenance expenses, operation expenses of Nanjing Paleontology Museum and personnel expenses. The annual income, including financial allocation, is very limited. After making ends meet, the institute will have to subsidize more than 3 million yuan, which is very stressful for a research institute that mainly carries out basic research.

　　At the same time, the scientists in the institute are also very enthusiastic about popular science work. "On May 18 this year, we hired more than 20 researchers in the institute as the first batch of science communication experts." Wang Yongdong said that this group of science communication experts actively participated in the writing of the exhibition outline and exhibition board explanations, the design of booths and exhibits, video shooting, and popular science lectures and activities.

　　Yongchun Zheng suggested that the state should establish a system of popular science as soon as possible, and subsidize popular science as it does scientific research, such as setting up a popular science fund, a popular science talent plan, and awards for popular science achievements. "Researchers can get project funding and national awards, and they can also be recognized by their peers, so they will naturally be willing to join them." Yongchun Zheng said.

　　Wang Yongdong also believes that the state can set up science communication projects in the Natural Science Foundation, and science communication awards can also be set up among the three major science and technology awards.

　　At the same time, respondents generally believe that popular science training and personnel training must be taken seriously. "After doing science popularization and science education, I found that this person is studying high-energy physics, and that person is studying applied mathematics and analytical chemistry. Does anyone study science? We need someone who can connect different disciplines and be compatible, and give these talents the overall scientific nourishment from the perspective of future talent training. " Yongchun Zheng said.

　　Wang Yongdong suggested that the science communication course should be set up as a compulsory course in science and engineering majors in universities, so that students can master the expressive ability of difficult content and the essentials and methods of integrating media communication. Only when they take up their jobs in the future can the results be clearly described and disseminated, so that the whole society and the general public can understand, understand and use them.

　 　　 　　　Recent epidemic situation in ChinaIn the process of getting up, there are some situations that deserve our attention.the most importantIsFalse negatives in nucleic acid detection. Intercepting relevant news, it was found that 8 confirmed patients in Shijiazhuang on the 22nd were repeatedly negative for nucleic acid detection, and 5 confirmed patients in Shijiazhuang on the 24th were repeatedly negative for nucleic acid detection.

　 　On the 22nd, there were 11 new confirmed cases in Shijiazhuang, including:

Case 1: Male, 52 years old, from Huangjiazhuang Village. On the evening of 21st.Ninth nucleic acid positive;

Case 11: Male, 67 years old, Xiaoguozhuang Village, husband of Case 2 on January 7th. On January 3, it was transferred to centralized isolation medical observation; On the evening of 21st.11th nucleic acid detectionFinally positive;

On the 24th, there were 7 new confirmed cases in Shijiazhuang:

Case 1: Female, 65 years old, Nanqiaozhai Village. Centralized isolation on the 11 th.Nucleic acid after 9 times, 22 positive.

Case 2: Female, 4 years old, Nanqiaozhai Village. Centralized isolation on the 11 th.Nucleic acid after 9 times, 22 positive.

Case 3: Female, 4 years old, Mi Jie, Chang ‘an District. Centralized isolation on the 13 th.Nucleic acid after 8 times, 23 positive.

Case 4: Female, 64 years old, Xiaoguozhuang Village. Centralized isolation on the 10 th.After 11 nucleic acids, 24 positive.

Case 5: Male, 34 years old, Xiaoguozhuang Village. Centralized isolation on the 8 th.After 11 nucleic acids, 24 positive.

Case 6: 34-year-old female, Liujiazuo Village, was positive for nucleic acid on the 5th, was diagnosed as asymptomatic infection on the 6th, and was clinically confirmed on the 24th.

Case 7: A 28-year-old male, living in Yuhua District, went to work by car at Zhengding Airport on weekdays. He was diagnosed as asymptomatic infected with nucleic acid on the 5th, and was clinically confirmed on the 24th.

Since the outbreak of COVID-19 last year, the topic of high false negative rate of nucleic acid detection has been the focus of attention. It has been reported that the positive rate of Covid-19 detection by fluorescence quantitative RT-PCR is only 30%-50% at present, which leads to extremely high false negative rate.

For Hongge, who doesn’t know much about the test, this paper analyzes the relatively high false negative test by searching articles and documents, and summarizes some reasons to discuss with you.

First, the incidence of COVID-19 suggests that it is highly possible to collect positive samples in a proper time.

Academician Yuan Guoyong’s team conducted this cohort study in Hong Kong Princess Margaret Hospital and Queen Mary Hospital. From January 22 to February 12, 2020, 23 hospitalized patients who were diagnosed as COVID-19 by laboratory examination of nasopharyngeal or sputum specimens were screened in the two hospitals.

A total of 173 respiratory specimens were collected from 23 patients. The researchers used RT-QCPR to determine the viral load in the samples. The results showed that the median viral load of respiratory tract samples was 5.2 log10 copies /mL (interquartile range was 4.1-7.0), and only 3 patients (13%) did not detect Covid-19 RNA in saliva samples.

The researchers observed that,The viral load in saliva was the highest in the first week after the patient developed symptoms, and then gradually decreased.Eight days after the patient developed symptoms, airway extracts were collected, and there was no obvious downward trend in viral load. Of the 21 patients who did not die,Seven people (33%) could still detect viral RNA after 20 days of symptoms, but this was not related to the severity of the disease.

AprilAccording to a study published in Nature Medicine, COVID-19 patients are most infectious before symptoms appear, and they begin to shed SARS-CoV-2 2 2-3 days before the first symptoms appear.

https://doi.org/10.1038/s41591-020-0869-5

The study, led by Eric Lau of the University of Hong Kong, involved 94 patients with COVID-19 admitted to the Eighth People’s Hospital of Guangzhou, China, 50% of whom were male, with a median age of 47 years. Among them, 61 of 93 patients were mild. Specifically, the researchers collected the throat swabs of 94 COVID-19 patients who were treated in the Eighth People’s Hospital of Guangzhou, China from January 21st to February 14th. From the onset of symptoms to 23 days after onset, 414 throat swabs were collected.

The results show that the researchers areThe high viral load was detected shortly after the patient developed symptoms, and then gradually decreased to the detection limit around the 21st day.There is no significant difference in viral load among different sexes, age groups and disease severity.

In addition, the researchers also analyzed 77 samples of "transmission pairs" from public data to assess how much time passed between the onset of symptoms in each patient. It assumes that the median incubation period (the time from infection to symptoms) is 5.2 days.The research team concluded that infectivity began 2.3 days before symptoms appeared, and peaked 0.7 days before symptoms appeared.

In the sensitivity analysis, the same estimation procedure is used, but assuming that the infectious attack is unchanged 1-7 days before the symptom occurs, thenIt was found that the infectivity reached its peak 0-2 days before the onset of symptoms, and the transmission ratio before the onset of symptoms was 46% to 55%.

The study also found that,The virus may start shedding 2-3 days before the first symptoms appear.After the symptoms appear, the viral load in the patient’s body decreases faster. This is consistent with the results of two recent studies. On April 1st, teams from Munich, Germany, Berlin and Cambridge, England published the article "Viro logical assessment of hospital patients with Covid-2019" on Nature. It was found that the shedding peak of Covid-19 occurred in the early upper respiratory tract infection.This shows that virus carriers may be the most infectious when they have mild symptoms or almost no obvious symptoms.

Brother Hong:From the above two documents, we can draw a conclusion that the virus shed and spread 2-3 days before the symptoms appear after infection, and after the symptoms appear, with the passage of time,The viral load of throat swab decreases gradually, and the viral load detected within 7 days after symptoms. If symptoms have existed for more than 20 days, the reliability of negative conclusion of throat swab is poor.

Solution:We need to publicize the law of the new crown to the people and medical workers, and improve our vigilance against COVID-19. It is best for patients to see a doctor in time, and doctors can also suspect this possibility. Only at the right time can we collect high-content samples and diagnose and control them in time.

Second, accurate sampling strategy is the best means to reduce false negative results.

In February, a study published by Medrxir, a pre-printed website, collected respiratory tract samples such as nasal swab, throat swab, sputum and bronchoalveolar lavage fluid (BALF) from patients diagnosed with COVID-19, and included 213 Covid-19-infected patients admitted to the Third People’s Hospital of Shenzhen from January 11th to February 3rd, 2020, who were diagnosed by Guangdong CDC. A total of 866 respiratory tract samples, including 490 nasal swabs, 205 throat swabs, 142 sputum samples and 29 BALF samples, were collected at the time of admission and after each time point. According to the collection date, the samples were divided into 0~7 days, 8~14 days and ≥15 days after onset. According to the guidelines on prevention and treatment of Covid-19 infection issued by National Health Commission, patients were divided into severe and mild cases.

Three groups were divided according to the sample collection time after onset, and the viral nucleic acid was quantitatively determined.The positive rate of viral nucleic acid in sputum samples was the highest in the group of 0~7 days after onset.The positive rates of severe and mild cases were 88.9% and 82.2% respectively.Followed by a nasal swab.(73.3% and 72.1% respectively),The throat swab again.(60.0% and 61.3% respectively). In mild cases, the positive rate of nasal swab and sputum samples is similar.

The positive rate of BLAF samples collected from 8 to 14 days after the onset of severe cases was 100%.However, the BALF samples of 3 mild cases were negative. In all cases, the positive rate of sputum samples was the highest in the 8~14 days after onset, which was much higher than that of nasal swab and throat swab. It is worth noting that the positive rate of throat swab in severe patients is only 50%, and that in mild patients is only 29.6%.

In the group ≥15 days after onset,The positive rates of BALF, sputum and nasal swab from severe cases were similar. In mild cases, the positive rate of sputum and nasal swab is similar, which is much higher than that of throat swab.

For the diagnosis of viral nucleic acid in COVID-19’s patients,Sputum samples are the most accurate, followed by nasal swabs. It is not recommended to collect throat swabs for diagnosis.

The difference between oropharyngeal swab and nasopharyngeal swab

anusswab

Brother Hong:

1. Oropharyngeal swab is the least painful and most acceptable, but it has to bear the consequences of high false negative results. My suggestion is to use it according to the epidemic risk in the first epidemic area.

2. The positive rate of nasopharyngeal swab is higher than that of oropharyngeal swab, which is why nasopharyngeal swab is introduced into laboratory examination in the fifth edition of Diagnosis and Treatment Plan for Pneumonia Infected by Covid-19 (the fourth edition is still pharyngeal swab). If we want to pursue accuracy, it is suggested to use it, or to use it when screening people in close contact or sub-close contact. At present, the examination of returnees in domestic reports seems to be nasopharyngeal swab method.

3. Alveolar lavage fluid can’t be used for screening in the general population, so it is suggested that hospitals with ICU should use it for screening severe pneumonia patients living in ICU for COVID-19 patients.

4. Deep expectoration seems to be the best sample, but many patients in COVID-19 have a dry cough, which may not be possible.

5、anusSwabs were used in Daxing epidemic in Beijing, which is the first time to use this method in the screening process. In some literatures,anusAlthough the positive rate of swabs is not high, as I remember, it seems to be more than 10%, but it does not seem to coincide with the patients with oropharyngeal swabs, suggesting that the virus may attack the gastrointestinal tract, and also suggesting that there may be the possibility of gastrointestinal transmission in Covid-19. Although the initial symptoms of some patients are gastrointestinal symptoms such as abdominal pain and diarrhea, there are also ACE2 receptors in the digestive tract, which is theoretically possible, but it has not been confirmed at present. So,anusMy suggestion is that swabs can only be used as a supplement to nasopharyngeal swabs, and it is better to select patients whose first symptoms are digestive tract symptoms more accurately, which is unlikely to be used as a means of large-scale screening.

Solution:It is best for National Health Commission to issue a guiding document for large-scale screening, and make detailed regulations on what population and what sampling methods to adopt under what circumstances.,When local governments encounter an outbreak in COVID-19, it’s best to ask professionals to act as consultants and make choices according to the actual situation.

Third, the consistency of sampling ability of sampling personnel affects the sampling results.

Garbage in, garbage out (garbage samples produce garbage results), which is a sentence that inspectors often say.

The sampling team is huge, and the ability of sampling personnel must be uneven. In addition, people may have such fears about sampling, which often leads to unqualified samples.

Generally, there is an internal standard in the molecular diagnostic reagent to monitor the detection process, for example, RNaseP is used as the internal standard. If both the sample response curve and the internal standard response curve displayed by the fluorescence PCR platform do not jump, it means that the quality of the collected samples may have problems or false negatives may occur due to improper experimental operation, which needs to attract the attention of medical workers. The RNaseP internal standard can monitor the sample collection and ensure the accuracy of the test results.

Note: RNaseP is ribonuclease P, which is one of the most important ribozymes in human body. It is ubiquitous in all organs, tissues and cells of human body, and can detect RNA nucleic acid fragments from human body samples, and can also be used as an internal standard.

And I privately asked the relevant person in charge of our city’s temporary inspection center. He told me that every day in our hospital, some samples were told that they needed to be re-sampled because the internal standard did not jump. Imagine that you didn’t wipe down a few cells in your throat swab collection, so will the negative of this nucleic acid be accurate?

Solution:Consistency training for nucleic acid sampling personnel will greatly reduce the human influence, and it is easier to standardize the sampling process by taking such sampling methods as nasopharyngeal swab. Our city seems to have trained the nucleic acid emergency sampling team very early. What about your city?

In addition, if in the environment of large-scale nucleic acid sampling, when testing under the standard of 5-mixed 1 and 10-mixed 1, according to the above principle of internal standard, it seems that there is no single-tube ability in the quality control of internal standard. Therefore, especially those in the emergency sampling team, we must pay attention to the standard sampling methods and remember to collect qualified samples as much as possible.

Fourth, choose the right oneSampling device

The virus preservation tube mainly consists of a sampling swab and a virus nucleic acid preservation tube (containing virus nucleic acid preservation solution). There are many kinds of virus preservation tubes on the market at present.It is very important for epidemic prevention and disease diagnosis to choose the appropriate virus preservation tube, reduce the infection risk of medical inspectors as much as possible, and keep the virus RNA stable without degradation..

The preservation solution UTM used in traditional virus collection tubes is based on Hank’s solution, with gentamicin, fungal antibiotics, BSA (V), cryoprotectant, biological buffer and amino acids added. Its main purpose is to maintain the virus activity within a certain temperature range, so that it is convenient for health and epidemic prevention departments to further isolate, culture and trace the virus and determine the pathogen. This kind of non-inactivated tube, which I call it, is good for further work, but the sameLive virus increases the infection risk of medical staff in the whole process of sample collection, transportation and testing!Personally, I think this kind of sampling tube for inactivated virus should be a better choice for disease control sampling.

And clinicalIn order to achieve the purpose of rapid detection, it is not necessary to cultivate the virus, but only to crack the virus, so as long as the integrity and stability of the virus nucleic acid can be guaranteed.nowCommonly known as inactivation tube.Many inactivation tubes in China are used.The inactivation component is guanidine salt, which is in this inactivation tube in our hospital.Guanidine salt can crack the virus, but it can’t protect the integrity of nucleic acid for a long time.The virus nucleic acid may have been degraded during the delivery of the sample to the laboratory, which will also cause a "false negative" in the detection. Many studies show that both temperature and time can affect the test results, so the COVID-19 Laboratory Testing Guide has clear requirements for samples to be tested within 24 hours after collection and transported at 4 degrees Celsius. If it is necessary to exceed 24 hours, it should be stored at -70 degrees Celsius.

And some manufacturers put forward another inactivation tube, a kind of.containNon-guanidine saltThe virus preservation tube containing protein denaturant can inactivate the virus and ensure the preservation of virus nucleic acid at room temperature.And the virus nucleic acid is stably stored for 7 days.Does not degrade.

Solution:

1, from sampling to testing, it is necessary to mark the time, so that quality control can be carried out on the preservation time, which is basically no problem in a better hospital.

2. For the front-line staff to do the corresponding training, they should know the advantages and disadvantages of various types of preservation tubes and adopt the best sampling tubes suitable for local conditions.

3. It is best for the country to recommend the selection of sampling tubes with the support of relevant experimental data.

5. Failure of reagents caused by virus mutation?

After the virus mutation in South Africa, Britain, Brazil and other places, there have been cases that turned positive after ten tests in various parts of the world, including China.The FDA recently warned that virus mutation has caused some reagents to fail, and listed several kits that may be affected by mutation. This means that virus mutation may have led to the failure of some nucleic acid detection or persistent false negative.

The FDA listed several kits that may be affected by mutation:

Accula SARS-Cov-2 detection (Mesa Biotech): If the virus mutates at the 28881st base (GGG to AAC), the detection of this kit will be affected;

TaqPath COVID-19 Combo Kit (Thermo Fisher Scientific): This kit detects three genes at the same time, and the variant B.1.1.7 appearing in Britain will affect one of the detection results;

Linea COVID-19 detection (Applied DNA Sciences): This kit detects two genes at the same time, and the variant B.1.1.7 appearing in Britain will affect one of the detection results;

Helix, an American company doing nucleic acid detection, also noticed the influence of virus mutation on detection. The company’s nucleic acid detection simultaneously detected three Covid-19 genes: ORF1ab, N, and S. Because the B.1.1.7 strain that appeared in Britain had deletion mutation in S gene, ORF1ab and N could be detected in the detection, but S gene could not be detected (4). This phenomenon is called "S gene withdrawal".

In addition, the sensitivity of reagents from different manufacturers to COVID-19 is different, and the country also organized a national evaluation of reagents last year. butIn an evaluation study on the consistency and detection ability of seven domestic novel coronavirus nucleic acid detection kits published by Chinese Journal of Laboratory Medicine in July, 2020, it was proposed that "some kits have poor detection ability for weakly positive samples,It is suggested that weak positive samples should be rechecked by kits from at least two manufacturers to ensure the accuracy of the results."

Several targets of nucleic acid detection in Covid-19 are ORF1ab gene, N gene and S gene.

In the Technical Guide for Laboratory Detection of Pneumonia Infected in novel coronavirus issued by China CDC (hereinafter referred to as the Technical Guide), the two targets of nucleic acid detection in Covid-19 are ORF1ab gene and N gene respectively.

On January 6th, the Weekly Report of China Center for Disease Control and Prevention published the results of gene sequencing analysis of two cases of Covid-19 infection in Shijiazhuang and Xingtai. According to the published results, the strain prevalent in Gaocheng, Hebei Province, is different from the strain found in other places in China recently, and is homologous to the strain reported in Russia last July, belonging to strain B.1.1.123

Coincidentally, the mutation happened at the 28881 ~ 28883 bases of the virus gene of this strain, and this is exactly the position of the forward primer of the N gene!

This also explains why there were many negative results at that time.

I guess this is one of the reasons why the criteria for judging nucleic acid positivity have also changed.The judgment position that the single target is still positive after retest is positive.

Figure/Current Criteria for Judging Positive Cases in Technical Guide

Solution:

1. Require manufacturers of nucleic acid reagents to conduct confirmatory experiments on the current mutant strains and propose technical solutions.

2, all localities should introduce at least two kinds of better quality detection reagents, for control use.

3. Information about the failure of test reagents that may be caused by mutated viruses should be effectively and widely reported in domestic laboratories.

Six, the standard implementation in the process of laboratory testing

the pastAccording to the guidelines issued by relevant institutions, the collected samples need to be inactivated at 56℃ before nucleic acid detection, which is very likely to degrade the Covid-19 nucleic acid, which will lead to the failure of normal detection and ultimately improve the false negative rate.In the early daysInactivation treatment is carried out for the sake of biological safety, to protect the staff engaged in testing from virus infection.

But later, there were many voices of doubt in the academic circles, becauseViral RNA is easily degraded by ribonuclease, because this enzyme has the highest activity at 60℃. Ribonuclease comes from two aspects, one is the sample cells, and the other is the foreign pollutants in the process of collection, preservation and transportation.

Last February, there was a similar research article.The high-temperature inactivation process before virus nucleic acid extraction significantly reduces the amount of detectable virus nucleic acid templates, which has been pre-published on the platform of scientific papers of China Academy of Sciences.

And last May,The Journal of Clinical Chemistry published the research of Chinese scholars on Covid-19’s false negative test.The study confirmed that,Thermal inactivation can cause the increase of Ct value reflected by PCR and cause false negative results.Specifically, 46.7%(7/15) of the weakly positive samples were false negative after inactivation (a surprising proportion). Another inactivation method is to inactivate the virus by dissolving the virus protein with guanidine hydrochloride. This study confirmed that guanidine hydrochloride had little effect on PCR reaction, and the false negative rate was low, although there was also a false negative rate of 13.3%(2/15).

Related address: https://academic.oup.com/clinchem/article/66/6/794/5815979

I also inquired whether there was a 56-degree inactivation step in the detection process of CDC in the United States. Although my English ability was poor, I didn’t see this step by machine translation.

Including some other documents retrieved, it is also very clear that 56-degree inactivation does have a great influence on weakly positive specimens.

No matter the Manual of Nucleic Acid Detection in Medical Institutions in novel coronavirus (Trial) on July 13th, 2020 or the Manual of Nucleic Acid Detection in Medical Institutions in novel coronavirus (Trial 2nd Edition) on December 30th, 2020, there are corresponding descriptions.For the laboratory that has been inactivated with the sampling tube containing guanidine salt, there is no need to inactivate at 56 degrees for 30 minutes.This is only true if non-inactivated sampling tubes are used.

However, I learned from the familiar laboratory leaders that this is not the case. Many laboratories still require samples to be pretreated at 56 degrees for 30 minutes regardless of whether the tubes are inactivated or not. I can understand that they are worried about hospital infection and laboratory exposure. But generally speaking, reducing the false negative rate, increasing the detection amount and taking corresponding measures to control the epidemic situation as soon as possible, I think the corresponding suggestions in the corresponding guidelines are also the best choice from the overall situation and supported by data.

Our laboratory should not control the occurrence of hospital sensation and laboratory exposure at the expense of reducing the detection rate, but should focus on stricter control of experimental steps, more cautious PPE wear and higher laboratory environment.

Solution:

1. It is suggested that the state give special instructions to laboratories at all levels on this matter.

2. It is suggested that the country should further study the preservation solution of sampling tubes, and if there is any preservation solution that can not reduce the detection rate at 56 degrees for 30 minutes, it can also be recommended.

The above zero zero always said a lot of points, mainly about how to reduce false negative conclusions, hoping to give you a reference.

It’s been many days since I wrote this afternoon, mainly considering Spring Festival travel rush. Although the scale of Spring Festival travel rush is reported to have dropped by more than 75% this year compared with previous years, the population flow is still very strong. We may face the rising trend of an epidemic after Spring Festival travel rush, and how to make the work better may be a more urgent need before us.

　　Iranian Foreign Minister Zarif. (Source: Student News Agency)

　　Overseas network September 29 th　Iranian Foreign Minister Zarif said that during his visit to new york, he had a telephone conversation with some members of the US Congress, but unfortunately, he did not hold face-to-face talks with them due to the shortened trip.

　　According to the semi-official Iranian Student News Agency (ISNA) on the 29th, Zarif told reporters when he was preparing to leave new york for Teheran that during his visit, he had talks with different groups in the United States, including some US congressmen. Zarif said that he was called by members of the US Congress. Due to the shortened itinerary, he could not coordinate these members to come to new york for face-to-face talks. He deeply regretted this. Zarif stressed that these US lawmakers have not made any demands on Iran, and Iran will not interfere in the US election. The Iranian side has held talks at the request of the other side and used these talks to show the true image of Iran.

　　Iranian President Rouhani and American President Trump. (overseas network puzzle)

　　When talking about the reports about the meeting between Rouhani and Trump, Zarif said that Trump was only trying to hold talks with Rouhani during his stay in new york this week, and Trump was unwilling to accept the lifting of sanctions as a prerequisite for the talks, so the bilateral talks could not take place. Zarif pointed out that direct talks between Trump and Rouhani have never been put on the agenda, and Iran is only willing to participate in the talks within the framework of the Iranian nuclear deal. Zarif also said that Trump did not promise to lift the sanctions after the talks, but Trump preferred to hold the talks directly and it was possible to lift the sanctions after the talks.

　　The Iranian side’s trip to the United States this time can be described as a thorn all the way. The 74th session of the United Nations General Assembly opened on September 17, 2019. Earlier, Iranian President Rouhani and Foreign Minister Zarif were delayed in obtaining American visas. Rouhani and Zarif "may cancel" their trip "if (the US) doesn’t issue visas within a few hours", Yitong News Agency reported on the 18th. On the same day, Trump said on the Iranian visa issue, "This matter does not depend on me." It was not until 19th that the Iranian delegation to the United Nations announced that the United States issued visas to the Iranian President and Foreign Minister, allowing them to attend the UN General Assembly in new york.

　　Iran said earlier that only when the United States returns to the agreement can the two sides contact. (Photo: Associated Press)

　　On the other hand, the repeated statements of the United States do not rule out the possibility of Trump meeting Rouhani during the UN General Assembly. On the 4th, after imposing additional sanctions on Iran, when asked about the possibility of meeting with Iranian leaders during the UN General Assembly, Trump said that "everything is possible". When he delivered a speech at the UN General Assembly on 24th, Trump also said that the possibility of direct dialogue with Iran was not ruled out, but the sanctions would not be lifted in advance.

　　However, the premise of the Iraqi side is that the United States must lift the sanctions before there can be talks. Iranian Foreign Minister Zarif said on the 22 nd that the premise of holding talks is that Trump promised to ease sanctions against Iran. Iranian President Rouhani also said in his speech at the general debate of the United Nations General Assembly on 25th that Iran has never bowed to foreign forces and refused to negotiate with those who imposed "the harshest sanctions in history".

　　Hubei Daily News (Reporter Wang Jing, arel) On December 30th, Ying Yong, secretary of the provincial party committee, presided over a forum to listen to the opinions and suggestions of grassroots party member cadres, heads of enterprises and universities and representatives of non-party people. Ying Yong stressed that it is necessary to conscientiously study and implement the spirit of the important speech delivered by the Supreme Leader General Secretary at the the Political Bureau of the Central Committee Special Democratic Life Conference, earnestly increase historical self-confidence, promote unity and unity, and enhance the spirit of struggle. Taking this democratic life conference as an important test of adhering to the "two establishments" and "two maintenances", we should further strengthen party leadership and party building, unite the wisdom and strength of the whole province, and provide for accelerating "building a fulcrum, walking in the forefront, and writing a new chapter"

　　At the forum, Huang Keli, secretary of Gucheng County Committee of Xiangyang City; Peng Qiang, secretary of Shengli Town, Luotian County, Huanggang City; Dong Shouzhi, secretary of Xiqiao Community, Tangjiadun Street, Jianghan District, Wuhan City; Wu Jing, secretary and chairman of Hubei Cultural Tourism Group Co., Ltd.; Jiang Liping, chairman of the provincial committee of Taiwan League and president of the provincial Taiwan Federation; Zheng Jun, member of the Central Committee of the Chinese Revolutionary Committee and president of Hubei Second Normal College; and Zhu Mei, full-time vice chairman of the provincial committee of the NLD. Tong Jinnan, member of Chinese People’s Political Consultative Conference and director of the State Key Laboratory of Biogeology and Environmental Geology of China Geo University (Wuhan), put forward opinions and suggestions on accelerating the development of county economy, improving the ability of grassroots cadres, deepening party building to lead grassroots governance, promoting the reform of provincial state-owned enterprises, continuously optimizing the business environment, and strengthening the training and use of non-party cadres. You should listen and take notes, interrupt from time to time, and discuss and communicate with you.

　　After listening carefully to the speech, Ying Yong said that everyone put forward good opinions and suggestions from various fields and aspects in combination with the actual work, which will help the provincial party Committee to grasp the facts, improve its work, better implement the decision-making arrangements of the CPC Central Committee, and help the Standing Committee of the provincial party Committee to hold a special democratic life meeting. We will listen carefully and fully absorb it, and take practical and effective measures to do a good job and promote implementation.

　　Ying Yong pointed out that under the strong leadership of the CPC Central Committee with the Supreme Leader as the core and under the scientific guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, Hubei has made decisive achievements in epidemic prevention and control and post-epidemic revitalization. It is a vivid and concrete educational practice for Hubei to hand over the qualified answer sheet for the Great War Examination, which is to strengthen the "four consciousnesses", strengthen the "four self-confidences" and achieve the "two maintenance". It is necessary to profoundly understand the decisive significance and role of the "Two Establishments", and deeply understand that resolutely safeguarding the core of the CPC Central Committee and the core of the whole party is the key to the party’s consensus and decisive choice at major moments, and it is an important guarantee for the party’s unity and victory. Constantly improve political judgment, political understanding and political execution, and always maintain a high degree of consistency with the CPC Central Committee.

　　Ying Yong stressed that it is necessary to thoroughly study and implement the spirit of the Sixth Plenary Session of the 19th CPC Central Committee and the Central Economic Work Conference, hold democratic life meetings with high quality and high standards, further strengthen the party’s political construction, guide the vast number of party member cadres in the province to learn wisdom and strength from the party’s century-long struggle history, vigorously carry forward the great spirit of party building, practice the initial mission, bravely move forward, do good deeds, do their best, effectively deal with the uncertainty of the external environment with the certainty of their own development, and continue to write about the high quality of Hubei’s economy and society.

　　Dong Weimin, member of the Standing Committee of the Provincial Party Committee and Secretary General, attended the forum.

　　September is autumn, the temperature drops gradually, the temperature difference between day and night increases, kindergartens and schools in various places open one after another, the mobility and aggregation of people increase, and the Mid-Autumn Festival holiday and other factors are superimposed, which easily leads to the spread and popularity of many infectious diseases. Henan CDC hereby reminds the general public to pay attention to novel coronavirus infection, whooping cough, norovirus infectious diarrhea, dengue fever, school tuberculosis and food poisoning this month.

　　Key tips

　　1. novel coronavirus infection

　　The epidemic situation of COVID-19 in our province showed a fluctuating upward trend since the end of July, and it showed a fluctuating downward trend after reaching its peak in mid-August. In autumn, students start school one after another, and the Mid-Autumn Festival is approaching, the flow and gathering of people increase, and the risk of infection in COVID-19 increases. In crowded places such as public transportation and shopping malls, we should persist in personal protection to reduce the risk of virus transmission.

　　Protective measures:

　　1. Strengthen the protection of high-risk groups. Targeted measures are taken for high-risk groups such as patients with basic diseases and the elderly, so that cases can be found in time and treated effectively, and serious cases and deaths can be reduced as much as possible. Timely discover and deal with possible cluster epidemics in places where people gather, such as kindergartens, schools and old-age care institutions.

　　2. Pay attention to personal protection. Residents should wear masks in their daily trips, minimize unnecessary gatherings and keep social distance. Maintain good personal and environmental hygiene, wash hands frequently, often ventilate, pay attention to rest, pay attention to nutrition and enhance physical fitness.

　　3. Use drugs rationally and see a doctor as needed. After infection, asymptomatic infected persons and mild cases should take care of themselves at home, reduce contact with their roommates, use symptomatic drugs rationally according to relevant guidelines, do a good job in health monitoring, and go to medical institutions in time if the condition worsens.

　　2, whooping cough

　　Pertussis is an acute respiratory infectious disease caused by Bordetella pertussis, and its typical clinical manifestations are paroxysmal, spasmodic cough and crowing inhalation roar. The disease has a long course and can last for 2-3 months, so it is called "whooping cough". It is mainly transmitted by air droplets, but also by direct contact with respiratory secretions of patients. The population is generally susceptible, and infants without immunization history are at higher risk.

　　Protective measures:

　　1. Standardize vaccination. Vaccination with DTP vaccine can reduce the risk of severe pertussis and death in infants. According to the requirements of the national immunization program for children, school-age children should be vaccinated with DTP vaccine as soon as possible, and school-age children who have not been vaccinated all the time should be replanted as soon as possible.

　　2. Seek medical attention in time. Especially when infants and young children have paroxysmal spastic cough or have their own sudden cough after similar cases around them, they should take the initiative to seek medical treatment in time to reduce the risk of epidemic spread and serious illness.

　　3. Do daily protection. Keep good hygiene habits, wash your hands frequently and ventilate frequently, cover your mouth and nose with elbows or paper towels when coughing or sneezing, and pay attention to reasonable work and rest and proper physical exercise. Try to avoid crowded and poorly ventilated public places.

　　3, norovirus infectious diarrhea

　　Norovirus is a group of non-encapsulated RNA viruses, which has the characteristics of strong infectivity, rapid spread, short immune protection time and general susceptibility of the whole population. It is the most important pathogen that causes acute gastroenteritis. It can be transmitted through polluted water and food, and can also be infected by aerosol inhalation or contact with items contaminated by virus. Shellfish such as oysters and raw fruits and vegetables are common foods that cause infection. It is easy to spread in crowded places such as schools and kindergartens. In the autumn school season, kindergartens, schools and other educational institutions should do daily protection and strengthen health monitoring.

　　Protective measures:

　　1. Maintain personal hygiene. Pay attention to washing hands frequently to prevent diseases from entering the mouth, especially before and after meals and before preparing and processing food.

　　2. Pay attention to the hygiene of diet and drinking water. Do not eat uncooked food and unpasteurized milk, shellfish and seafood such as oysters should be eaten after deep processing; Fruits and vegetables should be carefully washed before eating, and do not eat unclean fruits and vegetables; Separate raw and cooked foods to avoid cross-contamination; Ensure the safety of water sources, do not drink raw water, and the selection of bottled water should meet the hygiene standards.

　　3. Pay attention to standardization. The environment or the surface of an object polluted by the patient’s vomit or excrement should be cleaned and disinfected by trained personnel with chlorine-containing disinfectants or other effective disinfectants. In the process of handling patients’ vomit, excrement and disinfection, you must do personal protection, wear masks and rubber or disposable gloves, and carefully clean and disinfect your hands after cleaning.

　　4. Dengue fever

　　Dengue fever is an acute infectious disease caused by dengue virus. Its clinical manifestations are persistent fever, accompanied by severe headache, myalgia, joint pain, nausea, vomiting and rash. In severe cases, bleeding, shock, organ failure and even death may occur. The disease is mainly transmitted by the bite of Aedes mosquitoes. September is still the peak of mosquito activity, so we should keep good environment and room hygiene in our daily life, reduce mosquito breeding and reduce the risk of infection. At the same time, people who travel and work in dengue epidemic areas should pay attention to personal protection to prevent mosquito bites, and do a good job of self-health monitoring after returning from epidemic areas.

　　Protective measures:

　　1. Do a good job in mosquito control. Clean up the accumulated water in indoor containers such as flowerpots and drinking fountains in time, clean up domestic garbage and sanitary dead corners, and keep the room clean and tidy. Install screen doors and screens in the room, and use mosquito-repellent incense, mosquito killer and electric mosquito swatter to prevent and repel mosquitoes.

　　2. Personal protection should be done when going to dengue epidemic areas. You should wear long-sleeved clothes and trousers, spray repellent and mosquito repellent on bare skin, use mosquito nets when sleeping, and try to choose hotels with air conditioning or screens.

　　3. Do your own health monitoring. After symptoms appear, you should seek medical advice as soon as possible, and actively inform the doctor of the relevant residence history for early detection, early diagnosis and early treatment.

　　4. Use of personal protective equipment. Personal protective equipment such as mosquito nets and mosquito repellent can effectively prevent mosquito bites, thus reducing the probability of dengue virus infection. In areas with frequent mosquito activities, it is recommended to use mosquito nets or apply mosquito repellent to protect yourself.

　　5, school tuberculosis

　　Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many organs, and pulmonary tuberculosis infection is the most common. It is mainly transmitted by respiratory droplets, and healthy people may be infected by inhaling air droplets with tuberculosis. The main symptoms are cough, expectoration lasting for more than 2 weeks, chest tightness, low fever in the afternoon, fatigue, loss of appetite, emaciation, night sweats and so on.

　　Tuberculosis is one of the infectious diseases that schools focus on preventing and controlling. It is the beginning season of autumn recently, and it is a high incidence period of tuberculosis. Schools, parents and students should pay attention to the prevention and control of tuberculosis.

　　Protective measures:

　　1. Strengthen campus management. It is suggested that schools should strengthen the morning check-up, afternoon check-up and late check-up of students in school, implement measures such as tracking students’ absence from class and tracing the cause, and find tuberculosis patients and suspects in school as soon as possible.

　　2. Pay attention to personal protection and improve the body’s immunity. Pay attention to window ventilation, do not spit everywhere, and cover your mouth and nose with your elbow when coughing or sneezing. Reasonable diet, balanced nutrition, combining work and rest, ensuring adequate sleep and appropriate outdoor activities, enhancing physical fitness and improving body resistance.

　　3. Standardize the whole course of treatment. The whole treatment course of pulmonary tuberculosis is 6-8 months, and the whole treatment course of drug-resistant pulmonary tuberculosis is 18-24 months. According to the doctor’s standard treatment, most tuberculosis patients can be cured.

　　6. Food poisoning

　　Food poisoning is a major disease, which is caused by nausea, vomiting, abdominal pain, diarrhea and other symptoms after eating food contaminated by toxic and harmful substances or containing toxins. In September, the high temperature and high humidity weather continued in many places in China, which also created conditions for the proliferation of bacteria. Food is more prone to spoilage. With the large number of seafood on the market, it is necessary to pay attention to the pollution of seafood by Vibrio parahaemolyticus, which is easy to cause food poisoning.

　　Protective measures:

　　1. Pay attention to food hygiene and achieve "six noes": don’t eat uncooked and thoroughly cooked food, unclean fruits and vegetables, food of unknown origin, picking and eating wild mushrooms and wild plants, and don’t buy wild mushrooms picked and sold by individuals, and don’t buy wild mushrooms at mobile stalls.

Xinhua News Agency, Beijing, September 2ndQuestion: How to upgrade consumers’ enjoyment of trade-in support of overweight in various places?

Xinhua News Agency reporters Xie Xiyao, Li Xiaoting and Gong Liankang.

Recently, the "upgraded version" policy of promoting the trade-in of automobiles and home appliances at the central level has been introduced one after another. The reporter recently visited markets in Beijing, Hubei, Chongqing, Fujian and other places, and learned that all localities have introduced detailed rules for the replacement of old consumer goods in light of local actual conditions, expanded the coverage of subsidized products, upgraded subsidies, made the application process more convenient, and increased consumers’ willingness to purchase.

Government subsidies are superimposed on enterprises to make profits, and new subsidies for automobile replacement and renewal are added.

On the evening of August 27th, the reporter went to the Geely Yinhe Wuhan Star Experience Center in Hanyang District, Wuhan. The slogan of "trade-in" subsidy for cars in the store was everywhere, and many citizens went to the store to see cars and consult preferential policies.

The salesperson took the store’s best-selling model Geely Yinhe E8 as an example and calculated a "detailed account" for the reporter:

For a new car with an original price of 165,800 yuan, if the customer’s old car meets the scrapping conditions, the maximum state subsidy can be 20,000 yuan; Or transfer the car under his name, you can get a replacement subsidy of 12,000 yuan. During this period, you can also apply for a trade-in coupon of up to 2,000 yuan in Wuhan at the same time, plus a discount of more than 10,000 yuan from manufacturers and 4S stores, and the maximum superimposed discount for buying this new car can reach more than 30,000 yuan.

According to the national policy, for individual consumers who meet the provisions of the Detailed Rules for the Implementation of Vehicle Trade-in Subsidies and scrap old cars and buy new ones, the subsidy standard will be increased from 10,000 yuan for new energy passenger cars and 7,000 yuan for fuel passenger cars to 20,000 yuan and 15,000 yuan respectively. In addition to scrapping and updating, this policy will also include replacement and updating in the scope of subsidies, and support local governments to carry out replacement and updating independently.

At present, following the rhythm of national policies, local governments have successively launched trade-in schemes focusing on the local automobile market.

The national dicing and matching funds in Hubei Province are more than six times the size of the funds before the afterburner measures. The maximum subsidy for car scrapping and renewal is 20,000 yuan, and the maximum subsidy for replacement and renewal is 16,000 yuan.

Beijing has made it clear that the newly purchased new energy vehicles after replacement include not only pure electric vehicles, but also plug-in hybrid vehicles (including extended-range vehicles) and fuel cell vehicles, and all of them can enjoy replacement subsidies if they are transferred inside and outside Beijing.

Shanghai puts used cars in an important position in the trade-in policy, encourages the development of used car distribution business, and makes it clear that the average age of used cars will be reduced by one year by 2027 …

Government subsidies are superimposed on enterprises to make profits, new replacement and renewal subsidies are added, and consumers’ willingness to buy new cars is increased.

Up to now, the trade-in of consumer goods in Hubei has benefited more than 400,000 consumers, driving the sales of new cars and home appliances to 12 billion yuan. Wuhan has achieved the goal of trade-in of automobiles for the whole year ahead of schedule; As of mid-July, Hunan has received more than 8,600 applications for automobile scrapping and renewal subsidies, and more than 23,000 applications for replacement and renewal subsidies, which has driven automobile sales to exceed 5.5 billion yuan. From the release of the National New Deal to September 1st, the cumulative amount of old-for-new subsidies in Chongqing reached 9,748, and the cumulative sales of automobiles exceeded 1.837 billion yuan.

According to the data of the Ministry of Commerce, as of 10: 00 a.m. on September 1, more than 810,000 applications for car scrapping and renewal subsidies were received. From January to July, the national automobile retail sales reached 11.556 million, up 2.3% year-on-year. Among them, the retail sales of new energy passenger cars was 4.988 million, a year-on-year increase of 33.7%; The number of used cars was 10.992 million, a year-on-year increase of 6.3%.

The subsidy for home appliance replacement will be expanded, and the on-site application will be reduced immediately.

Mr. Zhou of Nanchuan District, Chongqing recently bought a Haier Class 1 energy-efficient air conditioner with a price of 2,499 yuan and enjoyed a government subsidy of 499.8 yuan for trade-in. "Government subsidies are very cost-effective, and it is very convenient to apply for money immediately." Mr. Zhou said.

On August 26th, Chongqing’s "upgraded version" green smart home appliances trade-in subsidy policy landed. On the first day of the implementation of the policy, the city issued a government subsidy of 8.165 million yuan, which directly led to the sales of home appliances of 42.6335 million yuan.

The reporter learned from the Chongqing Municipal Commission of Commerce that at present, the state’s pre-allocated funds to support trade-in have been issued to Chongqing, and the local governments will match the funds in proportion to jointly promote the trade-in of consumer goods.

The state has made it clear that eight types of household appliances enjoy a subsidy standard of 15% to 20% of the sales price, with a maximum subsidy of 2,000 yuan per piece. At the same time, support local governments to independently determine the varieties of subsidized "8+N" household appliances. Up to now, many places have successively issued implementation rules for the implementation of home appliance trade-in.

Chongqing has made it clear that individual consumers will enjoy 15% to 20% of the sales price of each type of household appliances when they purchase 11 types of household appliances with energy efficiency or water efficiency standards of Grade 2 or above; In terms of superimposed subsidies for enterprises, consumers can enjoy a 2% trade-in subsidy if they sell nine categories of old household appliances and buy any kind of products with energy efficiency or water efficiency of Grade 2 or above.

Beijing consumers can access the "Jingtong" applet through Alipay, WeChat, Baidu, Meituan and other channels, and receive the subsidy qualification codes of more than 10,000 household appliances in 8 categories, and enjoy preferential treatment in the payment link.

On the basis of eight types of household appliances, Guangdong has added three types of products, such as mobile phones, tablets and smart wearable devices, as well as other N-type products that are actually included in the scope of subsidies in various cities, forming an "8+3+N" product category.

From the central government to the local government, the subsidy policy has clearly defined the energy efficiency standards, and only subsidizes energy efficiency products of Grade 2 and above. "Trade-in is not a simple replacement of similar products, but a demand that tends to be higher-end, smarter, more environmentally friendly and more personalized, and supports the transformation and upgrading of household consumption through trade-in." Chen Yaoting, a professor at the Business School of Minnan Normal University, said.

Continue to open up new blocking points and smooth the resource circulation chain.

Recycling has always been a blocking point that affects trade-in consumption, and it is also the key to smooth the recycling of resources.

Fujian Quantong Resource Recycling Industrial Park, located in Zhangzhou Development Zone, Fujian Province, has a truckload of used household appliances entering the factory, weighing, unloading, acceptance, bar coding and warehousing, and then entering the dismantling process. Every day, about 2000 sets of waste household appliances are treated here in a standardized way.

Driven by the trade-in policy, Quantong has established strategic cooperation with recycling enterprises under Midea Group to realize the recycling system of products from sales, recycling to standardized dismantling.

The national policy is clear, all localities should strengthen the construction of digital platforms, learn from each other’s experience, strengthen data analysis, and timely and accurately grasp the information of the whole process of home appliances replacement, purchase and disassembly. The reporter visited and learned that under the guidance of the trade-in policy, the diversified recycling pattern of used household appliances is accelerating.

"Old household appliances are not limited to brands and years, and they can provide one-stop trade-in services such as free door-to-door dismantling of old machines and free transportation." He Yuanlin, general manager of Dahai Daming Trading Co., Ltd., a distributor of Haier Zhangzhou, said that the company is docking with dismantling enterprises with relevant qualifications, establishing a standardized recycling system for used household appliances, and at the same time promoting the development of community services for household appliances.

On September 2, Haier Zhijia Recycling Interconnection Factory was completed and put into operation in Laixi, Qingdao, with an annual dismantling capacity of 3 million units. Shijiazhuang city has perfected the comprehensive utilization system of renewable resources by the mode of "government+property+third party"; Hunan will include the recycling outlets of renewable resources such as waste household appliances into the construction of a convenient living circle for a quarter of an hour; Gree, Changhong and other home appliance companies actively adopt the "internet plus Recycling" method to provide professional old machine recycling services …

Insiders pointed out that with the increase in the number of places to promote the implementation of the old-for-new policy, it will drive the government, enterprises, platforms and other forces to join the field of recycling, and work together to improve the construction of the recycling network of used household appliances, so that consumers are "easier to get rid of the old and more willing to get new ones".

(nine) to develop good hygiene habits, don’t litter, especially the worn masks and related protective equipment. If it is possible, it should be centralized and harmless, and if it can’t be centralized, it should be burned by itself.

(ten) don’t refuse to check the temperature of the temporary epidemic prevention checkpoint. In response to the government’s call, migrant workers returned to the city in an orderly manner as required. Migrant workers should not bring live birds and other animals when they return to the city.

(eleven) the plan of the year lies in the spring, the epidemic situation should be prevented, and the production should not stop. We should do a good job in spring field management, spring ploughing and animal husbandry production.

Q:Can I order takeout during epidemic prevention?

Jin Yuming:

It is suggested that the take-away restaurant will distribute the containers containing food outside, and increase the frequency on the basis of the usual cleaning and disinfection requirements to disinfect the delivery staff’s vehicles. Do a good job of cleaning, disinfection and protection, and the possibility of virus transmission through take-away is relatively low. Be sure to wear a mask when taking takeout. It is suggested to carry out non-contact delivery, and inform the delivery staff to put the goods at the designated place, without the need for both parties to sign face to face. When taking takeout, you can bring disposable gloves, or use paper towels to separate your hands from the packaging bag. After taking the takeaway, you can remove the layers of packaging under the protection of gloves or paper towels and throw them into the trash can. Then use the soapbox flowing water to absorb it at the first time, or use antibacterial hand gel containing alcohol to clean your hands. However, we still suggest cooking by yourself and bringing meals. If you go to a restaurant or order takeout, it is recommended to order hot food instead of cold food; If possible, reheat the food before eating to ensure it is cooked thoroughly; Always remember to maintain hand hygiene, wash your hands before and after meals and after touching easily contaminated items.

Ru Yingying:thank you This concludes today’s press conference.
