The flu is not an ordinary cold! The whole country has entered the flu season and taught you how to prevent the flu!

On December 19th, 2024, China Center for Disease Control and Prevention released the China Influenza Surveillance Weekly, No.835 (December 9th-15th) in the 50th week of 2024. According to the test data, the positive rate of influenza detection in southern and northern provinces continues to rise, mainly with subtype A(H1N1)pdm09.

1. Can you tell the difference between influenza, influenza A and influenza B?

Influenza, referred to as "influenza" for short, is divided into four types: A, B, C and D. It is an acute respiratory infectious disease caused by influenza virus, which can cause outbreaks and epidemics worldwide.

Second, how is the flu infected?

It is mainly spread by droplets such as sneezing and coughing, and directly or indirectly contacts infection through mucous membranes such as mouth, nose and eyes. Contact with items contaminated by viruses can also be infected through the above channels.

In certain places, such as crowded, closed or poorly ventilated rooms, it may also spread by aerosol.

3. Who are the susceptible populations of influenza?

The incidence of influenza is high, and the whole population is generally susceptible. Some high-risk groups, such as the elderly, infants, obese people, pregnant women and patients with chronic diseases, have a relatively high risk of serious complications caused by influenza virus infection.

4. What’s the difference between flu and common cold?

Mild flu is often similar to the common cold, but fever and systemic symptoms are more obvious.

Common cold. Sneezing, stuffy nose, runny nose and cough are the main symptoms.

Flu Generally, the acute onset is mainly high fever, and the body temperature is mostly 39-40℃. Patients often have systemic symptoms such as chills, chills, headache, muscle and joint pain, fatigue, loss of appetite, and respiratory symptoms such as nasal congestion, runny nose, sore throat and cough. It can also cause gastrointestinal symptoms such as abdominal pain, abdominal distension, vomiting and diarrhea. In addition, there may be other symptoms such as chest pain when coughing, facial flushing and conjunctival congestion.

5. What are the treatments for influenza?

High-risk groups infected with influenza virus are easy to cause severe influenza, and antiviral treatment within 48 hours of onset can reduce complications, mortality and hospitalization time.

6. Influenza ≠ Three great tricks of common cold, scientific prevention

Step 1 get the flu vaccine

Vaccination against influenza is the most effective means to prevent influenza and reduce influenza-related severe illness and death. It can significantly reduce the risk of influenza and serious complications of vaccinators.

2. Drug prevention

It is suggested that close contacts with high risk factors of severe influenza should be given emergency temporary drug prevention after exposure, and it is recommended to take drugs within 48 hours.

3. Personal protection

(1) Wash your hands frequently. Wash your hands frequently and pay attention to washing your hands correctly. Do not touch your eyes, nose or mouth with dirty hands.

(2) cover your mouth and nose. When coughing or sneezing, cover your mouth and nose completely with paper towels or elbows, throw the used paper towels into the trash can in time, and wash your hands in time.

(3) less gathering. During the influenza epidemic season, the elderly, children, pregnant women, patients with chronic basic diseases and other high-risk groups should try their best to reduce going to crowded places and closed spaces, and wear masks if necessary. Advocate the public to wear masks in public transport, closed spaces and crowded places.

(4) Regular ventilation. Open the window for ventilation at least three times a day for at least half an hour each time to keep the indoor air fresh.

(5) Enhance immunity. Enhance physical fitness and dietary balance. Maintain a scientific diet and daily life, actively exercise and improve the body’s immunity.

Deeply understand the Supreme Leader’s Socialism with Chinese characteristics Thought in the New Era.

  The Communist Party of China (CPC) is a political party that attaches great importance to theoretical construction and is full of the spirit of theoretical creation. Listening to the voice of the times, reflecting the requirements of practice and writing a new chapter of great thoughts are important magic weapons for the party to unite and lead the people from victory to victory. The report of the 19th National Congress of the Communist Party of China summarized the theoretical innovation achievements of the Party since the 18th National Congress as Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, which realized the Party’s guiding ideology to keep pace with the times again. Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era is the latest achievement of Marxism in China, the crystallization of the practical experience and collective wisdom of the Party and the people, an important part of Socialism with Chinese characteristics’s theoretical system, and an action guide for the whole party and the people to realize the great rejuvenation of the Chinese nation.

  First, the latest achievements of Marxism in China

  The Communist Party of China (CPC)’s 96-year history is a history of Marxism in China. The study of the sinicization of Marxism in China is to stand at the forefront of the times and combine Marxism with China’s national conditions. Since the reform and opening-up, upholding and developing Socialism with Chinese characteristics has become a distinct theme in all the theories and practices of our Party. As General Secretary of the Supreme Leader pointed out: "Upholding and developing Socialism with Chinese characteristics is a great article, and Comrade Deng Xiaoping has defined the basic ideas and principles for it. The third generation of the party’s central leading collective with Comrade Jiang Zemin as the core and the CPC Central Committee with Comrade Hu Jintao as the general secretary have written wonderful chapters in this great article. Now, the task of our generation of communist party people is to continue to write this big article. "

  Since the 18th National Congress of the Communist Party of China, the development of China has stood in a new historical position in the pulse of the increasingly strong and rapid pace of the times. The situation at home and abroad is undergoing profound and complex changes, and some features have never been seen before. The global politics and economy are deeply blended and the problems are disputed. The complexity of relations among countries, economies and social organizations in the world was unimaginable in the 19th and 20th centuries. At the same time, the progress of modern science and technology, especially the information technology represented by the Internet, promotes the profound transformation of social form and social development mode, and new organizational forms, new production forms, new consumption forms and even new relationships between people, people and society, and people and nature are constantly emerging. More importantly, Socialism with Chinese characteristics’s miracle of practice and the spread of endogenous contradictions in western capitalism intensified, which made the rule of China in sharp contrast with the chaos in the West. The financial crisis, the refugee problem and more and more "black swan" incidents in the west have declared the bankruptcy of the final conclusion of history. Socialism with Chinese characteristics’s practice of "the scenery is unique here" fully demonstrates Socialism with Chinese characteristics’s road confidence, theoretical confidence, institutional confidence and cultural confidence.

  The historical orientation of contemporary China’s development is also facing a major transformation. After more than 60 years, especially more than 30 years of reform and opening up, Socialism with Chinese characteristics has entered a new era. China’s economic strength, scientific and technological strength, national defense strength and comprehensive national strength have entered the forefront of the world, and China’s international status has achieved unprecedented improvement. The face of the party, the face of the country, the face of the people, the face of the army and the face of the Chinese nation have undergone unprecedented changes, and the Chinese nation is standing in the east of the world with a brand-new attitude.

  It is based on the profound insight into the characteristics of the 21st century era and the scientific judgment of the development orientation of contemporary China that the CPC Central Committee with the Supreme Leader as the core constantly develops and innovates Marxism on the basis of unswervingly adhering to Marxism. Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era outlines the bright future of China and Marxism in the 21st century with a grand strategic vision, answers the issues and practical challenges faced by the new generation of Marxists with scientific theoretical logic, and systematically answers "What kind of Socialism with Chinese characteristics should be adhered to and developed in the new era and how to adhere to and develop Socialism with Chinese characteristics". With its profound summary of historical experience, profound revelation of historical laws, in-depth analysis of practical problems and in-depth thinking on future development, it has become the latest achievement of China-oriented Marxism.

  Second, an important part of Socialism with Chinese characteristics’s theoretical system

  Upholding and developing Socialism with Chinese characteristics is the solemn mission of the Communist Party of China (CPC) people and the solemn commitment of the Communist Party of China (CPC) people to China people. At the same time, it is a long-term and arduous historical task, and it is a new road that predecessors have never walked or even described in detail. The fundamental question of what kind of socialism to build and how to build socialism has long been solved, but it is far from finished. To accomplish our mission and fulfill our promises, we must be brave in practice, change and innovation, focus on the practical problems of China’s reform, opening up and modernization, focus on what we are doing, focus on the application of Marxist theory, focus on theoretical thinking on practical problems, and focus on new practice and development.

  Since the 18th National Congress of the Communist Party of China, the changes in domestic and international situations and the development of various undertakings in China have put forward a major task of the times, which is to systematically answer what kind of Socialism with Chinese characteristics and how to adhere to and develop Socialism with Chinese characteristics in the new era from the combination of theory and practice. Focusing on this major issue of the times, the CPC Central Committee with the Supreme Leader as the core adheres to the guidance of Marxism–Leninism, Mao Zedong Thought, Deng Xiaoping Theory, Theory of Three Represents and Scientific Outlook on Development, persists in emancipating the mind, seeking truth from facts, advancing with the times, seeking truth and being pragmatic, persisting in dialectical materialism and historical materialism, and closely combining the new conditions of the times and practical requirements. With a brand-new vision, he deepened his understanding of communist party’s ruling laws, socialist construction laws and the development laws of human society, made arduous theoretical explorations, made great theoretical innovations, and formed the Supreme Leader’s New Era Socialism with Chinese characteristics Thought.

  The most important and core content of this thought is the "eight explicits" summarized in the report of the 19th National Congress of the Communist Party of China: clearly upholding and developing Socialism with Chinese characteristics, with the overall task of realizing socialist modernization and the great rejuvenation of the Chinese nation, and building a prosperous, strong, democratic, civilized, harmonious and beautiful socialist modernization power in the middle of this century in two steps on the basis of building a well-off society in an all-round way; It is clear that the main contradiction in our society in the new era is the contradiction between the people’s growing need for a better life and the unbalanced development. We must adhere to the people-centered development thought and constantly promote the all-round development of people and the common prosperity of all people. It is clear that the overall layout of Socialism with Chinese characteristics’s career is "five in one" and the strategic layout is "four comprehensive", emphasizing firm road confidence, theoretical confidence, institutional confidence and cultural confidence; It is clear that the overall goal of comprehensively deepening reform is to improve and develop the Socialism with Chinese characteristics system and promote the modernization of the national governance system and governance capacity; It is clear that the overall goal of comprehensively promoting the rule of law is to build a legal system in Socialism with Chinese characteristics and a socialist country ruled by law; It is clear that the party’s goal of strengthening the army in the new era is to build a people’s army that listens to the party’s command, can win battles and has a good style of work, and build the people’s army into a world-class army; It is clear that the diplomacy of a big country with China characteristics should promote the construction of new international relations and the building of a community of human destiny; It is clear that the most essential feature of Socialism with Chinese characteristics is the Communist Party of China (CPC)’s leadership.The greatest advantage of Socialism with Chinese characteristics system is the Communist Party of China (CPC)’s leadership, and the Party is the highest political leading force. This paper puts forward the general requirements for Party building in the new era and highlights the important position of political construction in Party building.

  These "eight explicits" clearly and concisely explain the main contents of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, and constitute a scientific system with complete system, strict logic and internal unity.

  Iii. A guide to action for the whole Party and the people of the whole country to strive for the great rejuvenation of the Chinese nation.

  The sinicization of Marxism is to use the "vector" of Marxism to shoot the "target" of China and solve the practical problems in China. With Socialism with Chinese characteristics entering a new era, China’s social productivity level has improved significantly, and its social productivity has entered the forefront of the world in many aspects. The Chinese nation is standing in the east of the world with a brand-new attitude.

  As Comrade Deng Xiaoping pointed out in those years, "the problems after development are no less than when they are not developed", and may even be more complicated and intractable. For example, entering the new normal of economic development means that the well-used methods that we have been familiar with in the past may no longer work and can no longer be used. It is not only impossible to achieve effective development but also bring severe economic problems, environmental problems and even social and political problems. For example, when the reform entered the critical period and the deep water area, all the delicious meat was eaten, and the rest were hard bones. To deepen the reform in an all-round way, we must resolutely get rid of all the outdated ideological concepts and institutional mechanisms and break through the barriers of solidification of interests; For example, the "four major tests" faced by the party are long-term and complicated, and the "four dangers" faced are sharp and severe, and so on. These are all new and difficult problems before the Communist Party of China (CPC).

  How to effectively cope with major challenges, resist major risks, overcome major obstacles and resolve major contradictions, and push Socialism with Chinese characteristics forward in the new era requires that there should be a strategy to follow, a program of action, and the new practice should be based on the economy, politics, the rule of law, science and technology, culture, education, people’s livelihood, nationality, religion, society, ecological civilization, national security, national defense and the army, "one country, two systems" and the motherland. The report of the 19th National Congress of the Communist Party of China put forward the basic strategy of upholding and developing Socialism with Chinese characteristics in the new era around the implementation of Socialism with Chinese characteristics Thought of the Supreme Leader in the new era, and summarized it as "14 Persistences". Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era is an expression of the guiding ideology, which is called the basic strategy of Socialism with Chinese characteristics at the level of the action program.

  The basic strategy not only embodies the core, key and most important content of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era in the overall framework, but also embodies the overall grasp of Socialism with Chinese characteristics’s law in the new era. For example, it fully embodies Socialism with Chinese characteristics’s "five in one" overall layout and "four comprehensive" strategic layout. For example, it is emphasized that "development must be scientific development, and we must unswervingly implement the development concept of innovation, coordination, green, openness and sharing" and "we must uphold and improve China’s socialist basic economic system and distribution system". For example, it emphasizes that "the Party is the leader in everything, east, west, north and south", and requires the whole party to strengthen the "four consciousnesses", consciously safeguard the authority of the CPC Central Committee and centralize and unify leadership, consciously maintain a high degree of consistency with the CPC Central Committee in ideological and political actions, improve the system and mechanism of adhering to the party’s leadership, improve the party’s ability and determination to take the direction, seek the overall situation, formulate policies and promote reform, and ensure that the party always takes the overall situation and coordinates all parties. For example, it is profoundly clarified that "the people are the creators of history and the fundamental force that determines the future and destiny of the party and the country" and that "improving people’s livelihood and well-being is the fundamental purpose of development", which profoundly shows our party’s political stance, relying on strength and development purposes in governing the country, and so on.

  In short, the basic strategy embodies the achievements of our party’s theoretical innovation, practical innovation and institutional innovation since the 18th National Congress, and it is the party’s ideological, strategic, forward-looking and guiding action program in the new era. We must fully implement the party’s basic theory, basic line and basic strategy to better lead the development of the party and the people.

Can I still travel to Thailand? The travel agency said that there was no large number of unsubscribes, and the "May 1" trip to Thailand was still hot.

    Recently, the tourism safety of Thailand, a popular tourist destination, has been hotly debated. On March 24th, The Paper asked a number of travel agencies and online travel platforms, and they all said that there was no such thing as "receiving a large number of refunds".

  Thailand and Myanmar have voiced one after another.

  It can be seen that in the past few days, Thai officials have frequently voiced. According to Thai media reports on March 21st, the spokesman of the Prime Minister’s Office of Thailand, Anucha, revealed that the news about "it’s not safe to travel to Thailand" spread on social platforms in China recently was untrue, and Prime Minister Ba Yu ordered the Ministry of Tourism and Sports to clarify the situation at the cabinet meeting.

  On March 23rd, the Embassy of the Kingdom of Thailand in China issued a statement saying that Thailand attaches great importance to the quality and safety of China tourists and their good impression of Thailand. "Our library reiterates that since People’s Republic of China (PRC) allowed China tourists to travel abroad, Thailand has made full preparations for the arrival of China tourists and added many communication channels for China tourists, providing convenience and security for tourists to obtain information in Thailand and inform the tourist police of emergencies."

  In addition to Thailand, the Embassy of China in Myanmar also announced on March 23rd that Chen Hai, Ambassador of China to Myanmar, met with Lieutenant General Soto, Deputy Prime Minister and Minister of the Interior of Myanmar in Naypyidaw, and the two sides held talks on stepping up efforts to crack down on illegal cross-border criminal activities such as online fraud and gambling. According to the news, Suotu said that Myanmar is well aware of the dangers of illegal activities such as online fraud and gambling, attaches great importance to the position that China has repeatedly stated, and has stepped up efforts to crack down. In view of the recent continuation of illegal activities in Myanmar, Myanmar is willing to join forces with China and other relevant neighboring countries to resolutely crack down and effectively curb them, and jointly safeguard the friendly cooperation between Myanmar and China and the safety of people’s lives and property.

"I haven’t received the unsubscribe yet, but the reservation volume has decreased."

  On March 24th, many travel agencies told The Paper that there was basically no cancellation of orders related to Thai destinations. A person from a travel agency told The Paper: "The impact on the group tour is not reflected, and the group will not go to strange places." At the same time, a number of online travel platforms also said that they have not received relevant feedback for the time being. An insider of the online travel platform told The Paper: "The whole complaint about unsubscribe caused by Thailand, at present, the hotel and holiday products are in single digits."

  However, some insiders of the travel agency told The Paper that although the cancellation has not been received yet, the booking volume has decreased. "Related false statements are likely to have a great negative impact on tourism sentiment." The person said, "In fact, we have been to Thailand many times since the opening up, and it is safe to go to regular attractions and restaurants."

  Recently, many bloggers of short video platforms have published the content "Keep Safe" in Thailand. Some bloggers said in their comments: "If you want to go abroad, you must pay attention to safety, raise safety awareness, go hand in hand, and don’t trust any strangers."

  "May 1" outbound tour, Thailand’s heat is still in the forefront.

  In fact, up to now, Thailand is still one of the most popular destination countries for domestic outbound travel, ranking among the top in terms of search popularity and booking volume on online travel platforms.

  According to the big data of Mahoneycomb, the popularity of "May 1 outbound tour" in Mahoneycomb Station has increased by more than 110% in the past week, and Thailand, Malaysia, Indonesia, Japan and Spain are among the top five overseas destinations with the highest orders for May 1 holiday. As of March 23, Thailand is the overseas destination with the highest order volume during the May 1 holiday, and the tourism fever has increased by 150% in the past week.

  Ctrip data shows that since the beginning of this year, the popularity of tourism search in Chiang Mai on Ctrip platform has increased by over 9 times year-on-year, and the number of hotel reservations has increased by over 10 times. As of March 1st, Thailand’s Bangkok and Phuket ranked among the top five destination cities for outbound air ticket bookings in the Mainland during the May 1st holiday this year. The cities with the TOP10 bookings for outbound hotels in the Mainland during the May 1 holiday include Hong Kong, Phuket, Bangkok, Macau, Singapore, Tokyo, Koh Samui, Pattaya, Chiang Mai and Bali, and five of them are located in Thailand.

  In addition, The Paper previously reported that on March 22nd, the high-end tour group in Phuket, Thailand, with a unit price of 6,399 yuan for the May Day holiday under Lingnan Business Travel Group, was full. Most of the 19-member tour group was "post-95" and "post-00", and the trip was mainly based on experience, including speedboat sailing, catamaran fishing, punching in online celebrity buildings and local night markets.

  The price of outbound air tickets has been gradually decreasing.

  It is worth mentioning that, in view of the recent topic of "Thailand is too expensive to go", Ctrip-related people said that the price of outbound travel has actually been gradually decreasing since the "second-class B management". Taking air tickets as an example, the average one-way price of outbound air tickets on Ctrip platform in March was 2,124 yuan, which was 51.5% lower than the same period of last year. Chiang Mai was selected as the most affordable TOP3 destination among popular booking destinations, and lived in TOP1, the most affordable destination in Thailand.

  Where to go data also shows that from March 1 to 20, 2023, the booking volume of international flights (including Hong Kong, Macao and Taiwan) increased by 1.4 times compared with the same period in January 2023, and the average payment price of air tickets decreased by 7% month-on-month. TOP5 destinations were Bangkok, Hong Kong, Seoul, Kuala Lumpur and Macau.

  A senior person in the tourism industry said: "It is safer to sign up for a group tour. After all, travel safety is the most basic guarantee for a travel agency group tour. If you choose to travel freely, you must not do it for ‘ Seek excitement ’ Or go to the so-called ‘ Minority ’ Attractions. "

Research background

Hydrogen energy is a clean, carbon-free, flexible and efficient secondary energy with various forms of utilization. Vigorously developing the hydrogen energy industry and accelerating the clean transformation of energy structure are the ideal ways to achieve the "double carbon goal". Using renewable energy power supply system coupled with electrolytic water technology to produce decarbonized "green hydrogen" is the strategic direction of hydrogen energy industry development in the future. Electrolytic water reaction is a high energy consumption process, which is not easy to occur in thermodynamics and kinetics. The key to improve the overall efficiency of electrolytic water reaction lies in the research and development of efficient catalytic materials.

Introduction to the article

In recent years, a large number of catalytic materials without noble metals have been widely studied, but these materials only show good electrocatalytic activity in hydrogen evolution reaction (HER) or oxygen evolution reaction (OER), and there are few studies on bifunctional electrocatalysts that are effective for both HER and OER.

Recently, Zhou Xingwei, a research team of Professor Zheng Weitao of Jilin University, and others prepared a nitrogen-doped CoS on carbon fiber cloth (CC) by hydrothermal-annealing-hydrothermal method.2And MoS2Nanoplate-coupled bifunctional electrocatalyst (MOS/COS/CC), the prepared MOS/COS/CC catalyst has rich active sites and stable structure, and shows excellent HER and OER performance in alkaline electrolyte.

Innovation 2: MOS/COS/CC catalyst shows excellent HER and OER performance.

The comparison of HER and OER performance of MOS/COS/CC catalyst with commercial catalyst is shown in fig. 5. We compared different MoS in 1.0 mol/L KOH solution.2Growth time of MOS/COS/CC catalyst and commercial RuO2OER performance of catalyst. The linear voltammetric scanning curve (LSV) shows that MOS/COS/CC-6H shows the lowest overpotential (197 mV), which is lower than that of commercial RuO.2Catalyst. In addition, the MOS/COS/CC-6H catalyst has the lowest Tafel slope (64 mV dec-1), which indicates that the material has fast reaction kinetics, which is beneficial to the catalytic reaction. In addition, we compared different MoS in 1.0 mol/L KOH.2HER performance of MOS/COS/CC catalyst with growth time and commercial Pt/C catalyst. It is not difficult to find that MOS/COS/CC-6H also shows excellent HER performance. MOS/COS/CC-6H also has advantages over commercial RuO.2The stability of. The excellent catalytic activity and stability of MoS/COS/CC-6H benefit from MOS.2With CoS2The multi-stage structure of the material exposes more catalytic active sites, and the three-dimensional self-supporting structure grown in situ on CC shows excellent structural stability.

abstract

The oriented two-dimensional porous nitrogen-doped carbon embedded with CoS2 and MoS2 nanosheets is a highly efficient bifunctional electrocatalyst. The hierarchical structure ensures fast mass transfer capacity in improving the electroc atalytic activity. And the greatly increased specific surface area is beneficial to expose more electrocatalytically active atoms. For oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) tests in 1 mol/L KOH solution, only 194 and 140 mV overpotential are required to achieve a current density of 10 mA/cm2, respectively. Our research provides an effective strategy for synergizing the individual components in nanostructures for a wide range of electrocatalytic reactions.

Domestic HPV vaccine opens in Shenzhen! The price is about half cheaper than that of imports, which can be paid by medical insurance card.

On-site inoculation of domestic bivalent HPV vaccine in Tangwei Social Health Center of Fenghuang Street.

See Shenzhen Client Shenzhen News Network on July 1, 2020. (See Shenzhen Client, Shenzhen News Network reporter Liu Mengting Tang Liling)The first batch of domestic bivalent cervical cancer vaccine in Shenzhen has arrived!At 10: 55 am on July 1, Ms. Li, 41, was vaccinated with a domestic bivalent HPV vaccine with her friends at Tangwei Social Health Center, Fenghuang Street, Guangming District, Shenzhen. This is the first shot made by Shenzhen after the vaccine, which is completely produced by China with independent intellectual property rights, was approved for listing.

It is reported that Ms. Li made an appointment through the information sent by Tangwei Social Health Center on June 30, and the friends who came with her also vaccinated the domestic bivalent HPV vaccine after Ms. Li was vaccinated.

Zhu Ziyin, a staff member of Tangwei Social Health, said that on June 30, a vaccination notice was issued in the community of social health, and 12 people made an appointment in half an hour, and a total of 20 vaccines were prepared. The medical insurance card can be used for vaccination in this social health center, and the medical insurance card must be a first-class user. The account with a balance of more than 6387.85 yuan in the card can directly deduct the domestic bivalent HPV vaccination fee with the medical insurance card. "The social health center is regularly vaccinated against cervical cancer every Wednesday. You don’t need to make an appointment. You can go directly to the site to get the vaccination." She added.

The reporter learned from the Shenzhen Center for Disease Control and Prevention that up to now, only two social health centers in Shenzhen, Tangwei Social Health Service Center and Xinwei Social Health Service Center, have purchased domestic bivalent HPV vaccines. The reporter selected one of them to understand the vaccination situation at this stage.

The price of bivalent HPV vaccine is 329 yuan, which can resist about 85% of carcinogenic virus types.

Cervical cancer is one of the most common malignant tumors of female reproductive system in China. The data shows that in 2015, there were about 100,000 new cases of cervical cancer in China, with about 30,000 deaths, and about 84 people died of cervical cancer every day. More seriously, the incidence of cervical cancer is younger, and the proportion of patients under 35 years old is increasing year by year.

It is reported that tests in European and American countries have found that HPV16 and HPV 18 are carcinogenic viruses, which cause about 70% of cervical cancer. In China, these two viruses are closely related to 84% of cervical cancer due to ethnic differences. Vaccination as soon as possible can effectively avoid the invasion of these two most important carcinogenic viruses and reduce the risk of cervical cancer.

Completing HPV vaccination is one of the effective means to prevent cervical cancer. The bivalent HPV vaccine is aimed at HPV16 and HPV18 oncogenic viruses. At present, the price of a single domestic vaccine is 329 yuan/needle. Vaccinate two doses at the age of 9 ~ 14, the immunization program is "0-6", and the second dose is vaccinated within 6 months, including the service fee of 708 yuan; Women aged 15-45 years were vaccinated with three injections, and the immunization program was "0-1-6". The second injection was given one month after the first injection, and the third injection was finished within six months. The total cost was 1,062 yuan.

It is understood that the import of bivalent vaccine requires 580 yuan for each needle (three shots are required); The tetravalent vaccine costs 798 yuan per needle (three needles); Nine-valent vaccine needs 1298 yuan per needle (three needles); The domestic bivalent vaccine is priced at 329 yuan per needle (two needles in young age and three needles over 15 years old). Compared with imported vaccines, the domestic bivalent vaccine vaccination price is nearly half cheaper.

Who: 9-14 years old is the best age for HPV vaccination.

Cervical cancer is the most common malignant tumor in women after breast cancer. According to the statistics of the World Health Organization in 2018, there are about 570,000 new cases of cervical cancer and about 311,000 deaths worldwide every year. There are about 106,000 new cases and 48,000 deaths in China every year.

According to public information, in 2018, the World Health Organization called for the global elimination of cervical cancer. The vaccination coverage rate of girls aged 9-14 reached 90%, while the vaccination rate of girls aged 9-14 in China was less than 0.05%. In response to this incident, the National Health and Health Commission and other 10 departments jointly formulated the Healthy China Action-Implementation Plan for Cancer Prevention and Control (2019-2022), which strengthened the scientific propaganda of human papillomavirus vaccine (HPV vaccine) vaccination, implemented cancer prevention and control actions, promoted vaccination of school-age people, and effectively safeguarded the health of the broad masses of the people.

Cervical cancer is mainly caused by human papillomavirus (HPV) infection, and it is a preventable cancer. The preventive measures are cervical cancer vaccination and cervical cancer screening. It is generally believed that HPV vaccination is best before the first substantive sexual contact of women-the main route of HPV infection is sexual transmission. Inoculation after infection will not give full play to the vaccine effect. Accordingly, the World Health Organization has designated 9-14 years old as the best vaccination age.

The higher the titer of HPV vaccine, the better? Expert: Not really.

The bivalent vaccine is suitable for women aged 9-45, and the tetravalent vaccine is suitable for women aged 20-45. Women over 26 years old and 6 months old can also choose to take bivalent or tetravalent HPV vaccine to protect themselves.

"Price" represents the preventable virus species. Bivalent HPV vaccine can prevent more than 70% of cervical cancer; Tetravalent HPV vaccine can prevent more than 70% of cervical cancer and more than 90% of genital warts; Nine-valent HPV vaccine can prevent more than 90% of cervical cancer and more than 90% of genital warts.

"If we only make a simple judgment from the price, it will aggravate the tension of the nine-valent vaccine. Women aged 16 to 26 years and 6 months are suitable for the three HPV vaccines. It is recommended to analyze rationally and choose the vaccine that suits them." Experts from Shenzhen CDC said that the World Health Organization clearly pointed out in 2017 that the available evidence shows that bivalent, tetravalent and nonavalent vaccines have no difference in immunogenicity and effectiveness in preventing HPV-related cervical cancer of types 16 and 18, and all three vaccines can prevent most cervical cancers. The bivalent HPV vaccine has a higher infection prevention rate for the domestic population, reaching 84.5%, which is higher than the global average. If the purpose is to prevent cervical cancer, bivalent vaccine can fully meet the demand.

Experts also said that compared with the nine-valent vaccine, the two-valent vaccine and the four-valent vaccine have outstanding advantages, such as high cost performance, being paid by medical insurance and wide applicable age. Women of school age can make rational choices according to their actual situation.

About domestic bivalent HPV vaccine, you need to know

1. What kind of people are suitable for vaccination?

A: HPV vaccination is best before women have their first substantive sexual contact. The recommended age in the United States is 9 ~ 26 years old. The recommended vaccination age of bivalent vaccine is 9 ~ 25 years old, that of tetravalent vaccine is 20 ~ 45 years old, and that of nine-valent HPV vaccine is suitable for women aged 16 ~ 26.

2. Is it necessary for married and fertile women to be vaccinated with HPV?

A: Adult women who have had sex may have been infected with HPV, but HPV infection is limited to the inner layer of mucosal epithelium and will not induce a strong immune response. About 50% of women can detect antibodies after natural infection, but the titer is low, which is not enough to protect against reinfection. Therefore, it is necessary for married and fertile women to be vaccinated against cervical cancer.

3. Can pregnant women and lactating women be vaccinated? What should I do if I get pregnant after vaccination?

A: At present, there is no relevant data on vaccination of pregnant women and lactating women, and it is not recommended for pregnant women and lactating women to be vaccinated against cervical cancer for the time being. In fact, the harm of HPV is not as great as imagined. This part of women can wait for a while, and it is not too late to get HPV vaccine after the fetus is born and weaned.

The vaccine has not been found to have adverse effects on the fetus. Therefore, if you are pregnant unexpectedly within 6 months after vaccination, you can closely observe the pregnancy.

4. What is the difference between bivalent, tetravalent and nonavalent vaccines?

A: At present, there are three kinds of HPV vaccines listed in the world: bivalent, tetravalent and nine-valent. "Valence" represents the type of virus that the vaccine can prevent. Bivalent vaccine can prevent HPV16 and HPV18 virus infection. Tetravalent vaccine can prevent HPV infection of types 6, 11, 16 and 18. Nine-valent vaccine is aimed at nine subtypes of HPV6, 11, 16, 18, 31, 33, 45, 52 and 58. International research data show that the nine-valent vaccine can prevent 90% of cervical cancer.

5. Some people will feel dizzy and sick after being vaccinated with HPV vaccine. What is the current monitoring of adverse reactions of HPV vaccine?

A: Some women may have headache, fatigue and local reactions after being vaccinated with cervical cancer vaccine, such as pain, redness, itching, numbness, etc., but the data shows that people aged 9-45 are generally well tolerated after being vaccinated with HPV vaccine. At present, there are no vaccine-related deaths and teratogenic cases, but the safety testing of vaccines after large-scale marketing is still going on.

6. Can the current domestic and imported HPV vaccines guarantee lifelong immunity after vaccination?

A: HPV vaccine is still a new thing in the field of vaccine. It was born less than 20 years ago. From the international and domestic data, after the vaccination is completed according to the process, there is no need for replanting. But whether it is effective for life or not requires long-term observation to be clear.

7. Is it necessary to have regular screening after HPV vaccination?

A: Almost all cervical cancers are related to HPV, among which HPV types 16 and 18 are closely related to cervical cancer, and other types are 31, 33, 35, 39, 45, 51, 52, 58 and 59. At present, the best vaccine developed is the nine-valent cervical cancer vaccine, covering nine high-risk subtypes of HPV. These nine HPV subtypes caused 95% of cervical cancer cases, but 5% of HPV strains were still not covered by vaccine. Therefore, regardless of whether they have been vaccinated or not, it is recommended that women aged 18-65 should be screened once every 1-3 years.

China’s first COVID-19 mRNA vaccine was approved to start clinical trials.

Xinhua News Agency, Beijing, June 25th (Zhuang Yingna, Shao Longfei) The novel coronavirus mRNA vaccine (ARCoV), which was jointly developed by the Institute of Military Medicine of the Academy of Military Sciences and local enterprises, was officially approved by clinical trials in National Medical Products Administration on the 19th. This is the first COVID-19 mRNA vaccine approved for clinical trial in China.

Since the outbreak of the COVID-19 epidemic, the Institute of Military Medicine of the Academy of Military Sciences has deployed emergency scientific research to tackle key problems, and at the same time promoted the research and development of vaccines in COVID-19 with multiple technical routes. COVID-19 mRNA vaccine made in China is another high-tech vaccine variety approved for clinical trial after recombinant COVID-19 vaccine (adenovirus vector) in our hospital.

According to Qin Chengfeng, the project leader and researcher of the institute, mRNA vaccine is a new vaccine form in recent years. Its basic principle is to introduce mRNA expressing antigen target into the body through a specific delivery system, express protein in the body and stimulate the body to produce specific immune response, thus enabling the body to obtain immune protection.

Development and innovation of the concept of "one village, one product"

  The movement of "one village, one product" originated in Oita Prefecture in southwestern Japan in the late 1970s. After nearly 30 years’ practice, it shows that it is a model of making full use of local potential resources and capital to develop local economy with remarkable results. Under the new situation, it is of great practical significance to further understand the movement of "one village, one product" and take the development of "one village, one product" as a strategic measure for the construction of modern agriculture and new socialist countryside in China.


  First, the main achievements and practices of the development of "one village, one product"


  1. Cultivate leading industries and build a new platform for expanding regional economy.


  In the process of developing "one village, one product", all localities rely on resources for development, and take the road of "one household with many households, many households with the whole village, one village with many villages, and many villages are connected into pieces" by virtue of their characteristics, thus cultivating leading industries with their own characteristics, promoting industrial agglomeration and accelerating the formation of advantageous industrial areas. Professional villages and towns with industrial characteristics have accounted for more than 60% of the total number of villages and towns in Nanchang City, Jiangxi Province, and the number of "one village, one product" professional villages (natural villages) has grown to 236, and efforts have been made to build eight characteristic planting and breeding demonstration bases with specialization, scale and standardization as their advantages, providing a broad space for farmers to display their talents.


  2. Combined with agricultural industrialization, open up new ways for the development of agricultural organizations


  All localities pay attention to market development, plan the development of "one village, one product" according to the idea of industrialization, and cultivate various industrialized organizations such as leading enterprises and professional cooperatives in various forms and ways, which promotes the integrated operation of production, processing and sales and improves the degree of agricultural organization. Shaanxi has cultivated 80 strong villages, 5,000 large households and a number of sericulture processing enterprises. Relying on the support of strong villages and large households and driven by leading enterprises, it has built 70,000 mu of high-efficiency close-planting mulberry gardens and raised 200,000 silkworms, achieving a comprehensive income of 500 million yuan for sericulture production, 1 billion yuan for processing industry and 1.5 billion yuan for sericulture industry.


  3. Close to standardized production and form new measures for agricultural product quality and safety.


  In the process of developing "one village, one product", all localities started from the production link, actively promoted agricultural standardized production, promoted agricultural economical production, clean production, safe production and sustainable development, and effectively guaranteed the quality and safety of agricultural products. In 2006, the leading products of 17,030 specialized villages passed the national certification of pollution-free agricultural products or green food and organic food; There are 10971 professional villages with registered trademarks; There are 4154 professional villages that have won famous brand products at or above the provincial level; There are 2992 professional villages protected by geographical indication products. Yangshan Peach in Wuxi City, Jiangsu Province, has a planting area of more than 30,000 mu, and implements standardized management in the whole process of production, packaging, storage and transportation. The products have passed the organic food certification, won the title of "China Famous Brand Agricultural Products" and obtained the protection of geographical indications products, and the price is more than twice that of ordinary products. Heilongjiang "Wuchang Rice" has obtained the highest quality certification of "China Famous Brand Product" and is exported to both domestic and foreign markets.


  4. Expand various functions of agriculture and create a new bright spot of rural economic development.


  On the premise of ensuring the effective supply of agricultural products, all localities actively develop the functions of agriculture such as ecological protection, leisure and sightseeing, and cultural inheritance, vigorously develop environmental protection agriculture focusing on purifying the environment and conserving water sources, cultural agriculture focusing on promoting folk culture and inheriting farming civilization, and experience agriculture focusing on eating farm meals and doing farm work, which has cultivated new highlights in rural economic development. There are more than 50 farmers engaged in the production and processing of gongs and drums in Shangchuankou Village, Yangcun Township, Yangling District. Among them, 28 farmers have developed from the initial family workshop to a processing enterprise with a certain scale, and gathered along Yangwu Road, forming a spectacular gongs and drums processing street. The processed "Xinsheng brand" bronzes, "Weifeng brand" gongs and drums and "Hongda brand" cowhide drums are famous in the northwest bronze drum musical instrument industry.


  5. Cooperate with rural labor force and expand new channels for farmers to increase their income.


  All localities insist on proceeding from reality, give full play to their resource advantages, make agriculture suitable, industry suitable and business suitable, make leading industries bigger and stronger, and vigorously develop related industries such as processing, transportation and marketing, catering, etc., thus forming a situation of "one industry is thriving and all industries are flourishing", which not only extends the industrial chain, but also broadens employment channels and promotes farmers’ income. By the end of 2006, there were 43,433,300 employees in 41,293 specialized villages in China, accounting for 8.62% of the total number of rural employees. The per capita net income of farmers reached 4,560 yuan, 27% higher than that of farmers in China. There are 639 specialized villages such as Pearl Village, Citrus Village, Tea Village, Ramie Village and Flower Village in Changde City, Hunan Province, with nearly one million farmers. The per capita net income of farmers in specialized villages is 4,035 yuan, which is 785 yuan higher than that of farmers in the whole city.


  Second, the new requirements for developing "one village, one product" under the new situation


  1. Accurately grasp the development law of "one village, one product". First of all, we must respect the laws of nature, choose the most suitable agricultural products for local production to develop leading industries, and develop and cultivate "fine products" or "fist products" with obvious local characteristics that best reflect local advantages. Secondly, we must adhere to the market, and the characteristic agricultural products must meet the market consumption demand and have broad market space and prospects. Only in this way can such "fine products" successfully occupy the consumer market and create the best possible economic benefits. Thirdly, a moderate scale must be formed as soon as possible. Only large-scale operation can effectively promote the application of new varieties, new technologies and new machines and tools, truly realize regional layout, specialized production and intensive management, and enlarge the scale of featured products with market prospects. Fourth, we must take the road of industrialized operation, cultivate leading enterprises around the development of characteristic agricultural products, and establish an effective market linkage mechanism of "one village, one product" through leading enterprises to link production, storage, transportation, processing and sales on the spot, so as to enhance product level and market competitiveness. Finally, we can not only make full use of agricultural resources, but also integrate social elements of a place’s history, culture and customs into products, so that traditional products can form unique and competitive emerging industries.


  2. Deeply understand the important role of "one village, one product" in modern agriculture and new rural construction. "One village, one product" is based on adhering to the household contract management system, and through the implementation of contiguous production in one village or more villages, it realizes decentralized small production and integrated large-scale operation under the existing system, which is conducive to concentrating production factors and improving supporting facilities, and provides favorable conditions for agricultural intensification, standardization, mechanization and industrial production. "One village, one product" has promoted the development of agriculture and rural economy, increased farmers’ income, and accelerated the pace of getting rid of poverty in some places. It has become a strategic measure to promote the construction of new countryside, a strategic starting point for agricultural departments at all levels to build new countryside, and a strategic basis for sinking the focus of work to villages and ensuring the effectiveness of new rural construction.


  3. Update the development concept of "one village, one product". The development of "one village, one product" means the development of agricultural block economy through specialized production and industrialized management. Compared with traditional agriculture, its internal law, organizational form and development mode have changed greatly. We must change our development concepts and ways of thinking, strengthen our sense of innovation according to the requirements of modern agriculture, adhere to the concept of developing regional economy to guide the development of "one village, one product", accelerate the agglomeration of production factors to advantageous production areas, accelerate the centralized contiguous development, and accelerate the integration of production, processing and marketing, trade, industry and agriculture. It is necessary to strengthen market awareness, promote the development of "one village, one product" with the concept of brand drive, and accelerate industrial upgrading.


  Third, the future development orientation of "one village, one product": relying on modern agricultural organizations to promote "one village, one product"


  Modern agricultural organization is an effective organizational carrier to promote the movement of "one village, one product", and the rural specialized production of "one village, one product" is an important industrial support for the existence and development of modern agricultural organization. Facing the new situation of developing modern agriculture and building a new socialist countryside, according to the actual situation in China and the characteristics of various places, we can consider the following practice modes:


  1. The organizational form of "market+sales association+farmers"


  Because it is difficult for scattered farmers to effectively develop the market, expanding the leading product market and reducing the sales risk is one of the important ways to extend the industrial chain of "one village, one product". In the practice of "one village, one product" in all parts of China, many professional sales associations have been developed, which has improved the degree of organization of farmers’ entry into the market, and realized the promotion of industrial development by sales and the increase of farmers’ income. For example, Xinying Township, Xiji County, Ningxia, led by large growers and traffickers, set up a potato sales association. According to the operating mechanism of "market+agricultural association+farmers", it opened up sales markets for farmers, provided sales information, unified prices, unified packaging and unified sales, and gradually formed a one-stop process of production, supply and marketing, which effectively promoted the development of "one village, one product" in the local area. In 2005, the sales association directly led 600 local farmers to enter the potato market, and the per capita income of farmers from potatoes accounted for 57.9% of the per capita net income of that year.


  2. Through the organizational form of "professional association+farmers"


  To a certain extent, professional associations can make up for the shortcomings of low degree of organization of farmers. Providing farmers with a variety of services before, during and after delivery through professional associations can effectively reduce farmers’ market transaction costs, overcome the lack of decentralized management of individual farmers, reduce market risks and guide farmers to develop in the direction of "one village, one product". For example, in the nine years since the establishment of Xinye Vegetable Cooperative in Henan Province, farmers have been actively provided with excellent varieties, experimental demonstrations, technical services, agricultural materials management and product sales, and the area of "Bijiu" cabbage has been driven to reach 140,000 mu, realizing the scale and standardization of agricultural production. The products are exported to 16 provinces, Japan, South Korea, Russia and other countries, and the per capita net income of members is more than 8,000 yuan, which is twice as high as that of vegetable farmers outside the cooperative.


  3. The organizational form of "leading enterprises+associations+bases+farmers"


  Through the establishment of agricultural associations, on the one hand, leading enterprises can effectively convey product standards and quality requirements to production farmers and obtain stable sources of raw materials. Farmers’ own associations can bargain with leading enterprises on behalf of farmers’ interests, realize the balance of interests of both sides, and thus promote the development of "one village, one product". For example, Yongxing Town, Suining, Sichuan Province is supported by the characteristic angelica dahurica industry, with Sichuan Yinfa Resources Development Co., Ltd. as the leader, and drives farmers to carry out standardized and large-scale planting of angelica dahurica according to the operation mode of "leading enterprises+associations+bases+farmers". The annual planting area of angelica dahurica is 3,200 mu, the output is 1.28 million kilograms, and the output value is 7.68 million yuan, accounting for 13% of the town’s total output value, which gradually promotes the development of "one village, one product".


  However, at present, the organizational forms of farmers’ professional associations and cooperative organizations in many places in China are not standardized; In many places, the development of farmers’ organizations is seriously lagging behind; Most of them face the problem of shortage of funds; Some agricultural associations and cooperatives have poor personnel quality, irregular management, imperfect systems and low development levels. Generally speaking, the degree of organization of farmers entering the market is still relatively low, and the development of "one village, one product" is restricted. In the future, we must pay attention to the following aspects:


  First, we should highlight the dominant position of farmers in construction and decision-making. To develop the "one village, one product" movement, promote the construction of farmers’ economic organizations, or rely on modern agricultural organizations to develop "one village, one product", we need to respect the wishes and choices of farmers under the specific provisions of the cooperative law, and the government needs to support and guide them without coercion and service without interference, highlight the main position of farmers in developing "one village, one product" and building farmers’ professional cooperatives, and truly form "people-run, people-managed and people-benefited"


  Second, we should strengthen government guidance and services. At present, the development of farmers’ economic organizations in China is in the primary stage, and the movement of "one village, one product" has just started. These two important areas are in urgent need of government support. We should give necessary policy support in finance, taxation and credit, and take various forms to solve the financial difficulties of farmers’ development of one village, one product. It is necessary to strengthen the guidance on the development of one village and one product, follow the market rules to guide the development of one village and one product, find typical models through pilot and demonstration, summarize typical models and give key support. Guide farmers and grassroots cadres to learn, practice and develop one village with typical experience.


  Third, we must vigorously cultivate rural talents who develop one village and one product. At present, the scientific, technological and cultural qualities of farmers in China are generally low. Among the rural labor force, 87.5% have junior high school education or below, of which 37.3% have primary school education or below. The biggest difficulty in developing modern agriculture in China is the bottleneck of rural human resources. Drawing on the experience of developing "one village, one product" abroad, it is necessary to take the cultivation of practical technical talents and leading talents in rural areas as a focus of rural work, especially to cultivate outstanding talents who are innovative and challenging to meet the needs of the times and play a leading role in leadership and demonstration.


  Fourth, we should establish a risk guarantee mechanism that relies on modern agricultural organizations to develop "one village, one product". Agriculture is a fragile industry, facing not only market risks but also natural risks. Relying on farmers’ economic organizations to develop "one village, one product" is bound to face the impact of natural disasters at any time. Therefore, on the basis of support, the government should formulate risk prevention and risk rescue mechanisms to protect and make up for the losses caused by the practice of "one village, one product" and all related links of agricultural economic organizations in market-oriented operation under force majeure.
