In recent years, reports about "superbug" are common. It is no longer just the concern of medical workers, but has become a global problem.

"Superbacteria" actually does not refer to a specific bacteria, but generally refers to those bacteria that show resistance to at least three kinds of commonly used antibacterial drugs in clinic. Its academic name is "multi-drug-resistant bacteria".

In the face of "superbugs", only by understanding their characteristics and transmission mechanism can we better slow down their production and curb their spread.

"past lives" of Multi-drug Resistant Bacteria

Penicillin was discovered by alexander fleming in 1928. This powerful "sharp weapon" for treating bacterial infections saved countless lives in World War II. However, with the widespread use of penicillin and other antibacterial drugs, the first superbug in history-methicillin-resistant Staphylococcus aureus appeared, and then more and more superbugs appeared.

According to the report of China Bacterial Resistance Monitoring Network, the main clinical problem in China is Gram-negative bacilli which are resistant to carbapenems. The data in the first half of 2023 showed that the resistance rate of Acinetobacter baumannii to carbapenems was as high as 79.5%. These shocking data highlighted the seriousness of bacterial resistance in China.

In 2022, the authoritative medical magazine The Lancet published a survey of 204 countries and regions around the world in 2019. The study showed that antimicrobial resistance directly led to more than 1 million deaths, which even exceeded the number of people killed by malaria or HIV infection; The number of indirect deaths is even more alarming: nearly 5 million people. In 2016, the global research report on drug-resistant bacteria infection commissioned by the British government showed that by 2050, nearly 10 million people will lose their lives every year due to antimicrobial resistance.

Dr Margaret Chan, former Director-General of the World Health Organization, once pointed out that with the increasing and spreading of multidrug-resistant bacteria, common infection may once again become a fatal threat. This is not an alarmist. When human beings encounter the dilemma of no medicine available, even trivial wounds or respiratory infections may easily take their lives, and human beings will undoubtedly return to the dark period before the discovery of penicillin.

Why do drugs "fail" to bacteria?

Drug resistance of bacteria refers to the tolerance of bacteria to antibacterial drugs, which can be divided into congenital drug resistance and acquired drug resistance. Congenital drug resistance refers to the innate tolerance of bacteria to certain antibacterial drugs, which can be passed down from generation to generation; Acquired drug resistance means that bacteria "acquire" drug resistance genes due to spontaneous gene mutation or from other drug-resistant bacteria. Drug-resistant bacteria usually refer to acquired drug-resistant bacteria.

Drug resistance of bacteria is actually the result of natural selection in the process of evolution. In the process of its growth and reproduction, the reasons for promoting drug resistance involve many aspects, such as gene mutation or variation of bacteria, improper use of drugs and decreased immunity of the body, which may be the potential reasons for drug resistance.

The abuse of antibacterial drugs is an important factor leading to bacterial drug resistance. "Abuse" is mainly manifested in two aspects: unreasonable use in the treatment of human diseases and excessive and improper use in animal husbandry. Due to the selection pressure of antimicrobial agents, those bacteria with drug resistance will be naturally selected and multiply, thus accelerating the reproduction and spread of drug-resistant bacteria.

Multi-drug-resistant bacteria are mainly transmitted through contact, such as blood, sputum, urine or secretions of patients carrying multi-drug-resistant bacteria; Or contact with equipment, fabrics and pools contaminated by multi-drug resistant bacteria; For respiratory tract infection or colonization of multidrug-resistant bacteria can also be spread through droplets.

Antibacterials that have been "misunderstood"

The public’s understanding of antibacterial drugs is relatively limited, which leads to drug abuse becoming a common problem. There are 10 common misunderstandings in the use of antibacterial drugs, which need to be corrected as soon as possible:

1. Antibacterials are omnipotent anti-inflammatory drugs;

2. Do not distinguish the causes of colds, and use antibacterial drugs;

3. Antibacterials are the first choice for fever;

4. Diarrhea is inflammation, and it is best to use antibacterial drugs;

5. Broad-spectrum antibacterial drugs have stronger antibacterial ability, and the therapeutic effect is often better than narrow-spectrum antibacterial drugs for specific pathogens;

6. Newly listed and expensive antibacterial drugs are preferred;

7. The combination of multiple antimicrobial agents can effectively control infection;

8. It doesn’t matter if antibacterial drugs are frequently replaced;

9. Self-preventive use of antibacterial drugs during the high incidence of respiratory diseases in winter and spring.

10. The medication is not standardized, not enough, and the medication will be stopped if the symptoms improve slightly.

Abuse of antibacterial drugs will not only lead to bacterial resistance, but also lead to a series of serious adverse reactions, among which allergic reactions are particularly common, such as itchy skin, rash and other symptoms, and even life-threatening conditions such as anaphylactic shock may occur in severe cases; Some drugs may also cause nervous system symptoms, such as headache and dizziness. Some antibacterial drugs can also have toxic effects on hearing and kidneys; Abuse of antibacterial drugs will destroy the balance of flora in the body, which will cause a large number of inhibited bacteria to multiply and cause double infection.

Standardize drug use and prevent drug resistance

Remember 7 points.

1. Don’t buy drugs at will: Most antibacterial drugs belong to the category of prescription drugs. You must issue a doctor’s prescription when buying them, and you can’t buy them online or in a physical pharmacy at will.

2. Don’t choose your own medicine: When choosing which kind of antibacterial drugs to use, it should be judged by professional doctors according to the condition and clinical test results, not just by advertising or personal experience.

3. Do not use drugs at will: When using antibacterial drugs, we should follow the doctor’s advice to ensure that they are taken after professional diagnosis in the hospital, and do not blindly abuse drugs, especially for some daily ailments (such as colds), it is not appropriate to use antibacterial drugs easily.

4. Do not stop taking drugs without authorization: Once you use antibacterial drugs, you must follow the doctor’s instructions and take the drugs on time, according to the dosage and according to the course of treatment.

5. Pay attention to personal hygiene: frequent hand washing, more ventilation and avoiding close contact with patients are helpful to prevent infection.

6. Strengthen exercise: enhance physical fitness and immunity, and reduce the use of antibacterial drugs from the source.

7. Don’t throw drugs at will: expired drugs belong to harmful waste, so they should be thrown into the hazardous trash can to prevent criminals from recycling them. Garbage sorting, protect yourself and others.

The doctor concluded:

The increasingly serious problem of drug-resistant bacteria has become a major challenge in the field of global public health, which is attracting widespread attention from the medical community, government and society. In daily life, we should pay attention to developing healthy living habits, ensuring clean diet, actively exercising to enhance our immunity, and at the same time, we should follow scientific principles and standardize the use of antibacterial drugs. The whole society needs Qi Xin to work together to slow down the emergence of drug-resistant bacteria and curb its spread.

　　The year of the horse has arrived, and everything is renewed. Since the birth of human beings, there has been an inseparable connection with horses. As the closest partner of human beings, there are countless movies with "horse" as the role. The Spring Festival of the Year of the Horse is about to be celebrated, and the protagonist of the horse can’t be missing from TV and mobile phones. Let’s cut short the gossip here. We recommend several films related to horses in detail on "Horse", so that readers can get touched again through the power of the films.

　　Little horse king

　　There are countless movies about horses, but there are not many movies featuring horses. The Little Horse King is a story about struggle, struggle, freedom and responsibility from the perspective of a horse.

　　The story is set in the vast western part of the United States. It tells the story of the wild horse king Spirit and his ethnic group living a quiet life. When Spirit first saw human beings, he was arrested and trained as a war horse. But just as the English title (Spirit) is literally translated as faith, Xiao Ma Wang’s faith is freedom. After being captured again and again, he fought again and again, fighting for the freedom and home he loved.

　　Pentium age

　　This is a story about a loser. The three people in the story are all frustrated in life at the beginning. This is also a story about persistence, and the protagonists are struggling in the low period of their lives. The story is set in the Great Depression in the United States. A bicycle repairman made money by importing cars. Later, he bought a small horse and trained with a former boxing champion and an actor to win the race.

　　Pentium Age is a typical inspirational movie with the main theme, and the story is adapted from a true story. The actor who played the rider was the actor of Spider-Man, who was hot at that time, and also appeared in the topic film The Great Gatsby last year. The whole movie is positive, just like the feeling of the horse in the movie, "unruly and unwilling to give in."

　　the horse whisperer

　　This film, which focuses on horses, is adapted from The Horse Whisperer, a novel of the same name by British novelist Evans. At the beginning of the movie, it is a magnificent horse running back and forth. The story describes that a 14-year-old girl was injured by falling off a horse, so her mother sent her daughter and the horse to a ranch in Montana, so that the horse trainer Tom could treat the injured person and the horse at the same time. And this woman also found love under the call of nature.

　　Man is a social animal and needs communication and cooperation to survive. But there is always an unbreakable gap between people, and communication is so difficult. "The Horse Whisperer" in the film is actually the embodiment of people’s longing for "the speaker".

　　War horse

　　Spielberg finally completed the last piece of his epic war trilogy in 2012. From Schindler’s List to Saving Private Ryan to War Horse, as always, humanistic care is reflected through the cruelty of war.

　　This time, he took a warm route and magical style. The film is set during World War I, and tells an epic legend about loyalty, courage and strength through the deep friendship between a war horse and a boy. This kind of human and animal theme is difficult to shoot and go deep into, but Lao Si did it. (Li Yinghua) (Editor/Intern Yao Yujiao)

1905 movie network news July 26th, 2023 is the fourth anniversary of the film’s release. The film officially released a commemorative poster in which Nezha’s family and Ao Bing piled sand on the beach to celebrate Nezha’s birthday. The essay said: "Thank you for starting from scratch and accompanying Yi Er and C C all the way! When we meet again, we will grow into a majestic look. "

Four years ago today, Ne Zha was officially released, which eventually swept 5.035 billion box office, ranking fourth in the box office of China film history. The sequel to the film has been approved and the first poster has been published. It is expected to be released in 2024. I look forward to seeing you on the big screen in Aobing, Nezha!

　　The United States is the initiator of the Russian-Ukrainian conflict and continues to profit from it. The United States increased its sanctions against Russia, which made its European allies pay for it, while taking advantage of it.

　　The United States makes "energy wealth" and Europe suffers from high natural gas prices.

　　EU countries were highly dependent on Russian energy, and about 30% of imported crude oil and 40% of imported natural gas came from Russia.

　　After the outbreak of the conflict between Russia and Ukraine, the United States pressured European allies to impose sanctions on Russia, trying to cut off the energy links between Russia and European countries, and turned the energy demand to the United States in an attempt to make an "energy fortune".

　　On March 25, the United States and the European Union launched an energy cooperation plan, which will expand the export of liquefied natural gas from the United States to the European Union. According to the data of Luft Company, a data provider of American financial market, in the past March, the export of liquefied natural gas in the United States was about 7.43 million tons, an increase of nearly 16% from the previous month and a record high. Among them, Europe has become the largest export destination of liquefied natural gas in the United States for four consecutive months, accounting for about 65% of American exports.

　　However, the transportation and storage costs of liquefied natural gas (LNG) from the United States to Europe are higher, and the construction of related facilities is complicated, which can not fully meet the demand of Europe. European countries can only bear the skyrocketing natural gas prices.

　　Europe’s reduction of Russian oil imports has caused oil prices to soar.

　　Russia is the second largest oil exporter in the world after Saudi Arabia. After the outbreak of the conflict between Russia and Ukraine, European countries imposed sanctions on Russia, which led to a decrease in oil supply from Russia. Gunnvor Group, an energy trading giant, warned that if Russian oil supply continued to decrease, Europe would face an "extreme shortage" of oil, which led to a sharp rise in oil prices.

　　However, the United States continues to profit from it and imports a lot of Russian oil. Popov, Deputy Secretary-General of the Russian National Security Council, said on the 3rd that the volume of oil imported by the United States from Russia increased by 43% in the last week, reaching 100,000 barrels per day.

　　American military-industrial complex makes use of European security dilemma to make "war money"

　　In addition, the Russian-Ukrainian conflict has caused European countries great anxiety about European security. It is difficult for Europe to get out of the security dilemma and can only increase investment in national defense. On March 27th, the German government announced that it would increase the defense fund by 100 billion euros, raising the defense expenditure to more than 2% of GDP. Not surprisingly, this big piece of "fat meat" should mainly fall into the mouth of American arms giants. Since the situation in Ukraine became increasingly tense in October last year, the share price of American military giants has risen dramatically and earned a lot of money.

　　At the same time, since the conflict between Russia and Ukraine on February 24, the US dollar has been sought after because of the rising risk aversion in the market. In March, the cumulative increase of the US dollar was 1.7%, and the increase in the first quarter was as high as 2.8%.

　　Peskov: Europe needs to wake up from "American whiskey"

　　Obviously, the United States has strengthened its ties with Europe in military, diplomatic and energy supply through the Russian-Ukrainian conflict. Thierry de Mont Brial, president of the French Institute of International Relations, bluntly said that Europe would suffer more and more from being kidnapped by the United States, and the Russian-Ukrainian conflict once again "made Europe understand the importance of taking its destiny into its own hands and striving for strategic autonomy".

　　Russian Presidential Press Secretary peskov said on the 2nd that Russia-Europe relations are unlikely to improve in the near future. He said that only when Europe "wakes up from American whiskey" and realizes that its own destiny is in its own hands, not the United States, can the relationship between Russia and Europe be repaired.

　　Driven by artificial intelligence and the new generation of information and communication technology, the automobile industry is accelerating the transformation, and intelligent networked vehicles have become the key direction of the global automobile industry transformation. However, development and risk coexist. According to the monitoring data of China Information and Communication Research Institute, in 2023, there were 8.05 million attacks on domestic car networking service platforms, a year-on-year increase of 25.5%.

　　Intelligent driving, safety first. How to fasten the network "safety belt" for "smart car"? () Experts gave the answer when interviewed by CCTV →

　　In order to further improve the technical level of information security protection of China’s automobile products, strengthen the ability of industrial chain risk prevention and response to cyber attacks, and build a baseline of automobile information security protection, the Ministry of Industry and Information Technology has organized the formulation of the mandatory national standard GB 44495-2024 "Technical Requirements for Vehicle Information Security" (hereinafter referred to as the "Standard"), which will be officially implemented on January 1, 2026.
