Is there a “magic medicine” for the treatment of new coronary pneumonia?

  On the rumor list, health topics have always been among the top, and people will step into the “pit” if they don’t pay attention. Some of them are concocted by new hot spots, while others have come back after a facelift.
  There are many rumors like this: the veterinary drug ivermectin is the “magic medicine” for the treatment of new coronary pneumonia; a single shot can catch AIDS; some people feel chills because of their “fear of cold constitution”; fitness artifact foam shaft can thin calves …

  ”There is no such thing as a’fear of cold constitution’ in medicine.” According to Zhou Shengyuan, director and deputy chief physician of the Prevention and Treatment Center of the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, TCM says that “frigidity” mostly refers to the body being attacked by external cold pathogens. , And has nothing to do with “fear of cold constitution”.

  [Rumor] Ivermectin is the “magic medicine” for the treatment of new coronary pneumonia?
  [The truth] It cannot be cured, and it is dangerous to take a large amount
  . Recently, the news about “U.S., India and other countries using veterinary drug ivermectin for the treatment of new coronary pneumonia” has been circulated. For a time, ivermectin, a veterinary drug, was regarded as the “magic medicine” for the treatment of new coronary pneumonia.
  Everyone hopes that drugs for the treatment of new coronary pneumonia will come out. This wish is good, but the facts have proved that the treatment method is not reliable, and there have been incidents of “trying the medicine” in the United States that have caused poisoning.
  According to reports, Ivermectin is a broad-spectrum antiparasitic drug, mainly used to eliminate various parasites in the gastrointestinal tract of cattle, sheep, horses, pigs and other animals, as well as poultry gastrointestinal nematodes and ectoparasites.
  It is a rumor that pushed this veterinary drug to the “sacred altar”. According to an article published in the journal Antiviral Research by the research team of Monash University in Australia, Ivermectin can inhibit the growth of the new coronavirus within 48 hours. However, the results of this study are premised-Ivermectin can inhibit the growth of the new coronavirus in in vitro experiments, but the mechanism of its effect on the new coronavirus is not clear, and there is no evidence that it can treat the new coronavirus in the human body. Effect.
  Merck, one of the manufacturers of ivermectin, said that existing data do not support the use of the drug as a treatment for new coronary pneumonia.
  The U.S. Food and Drug Administration (FDA) also issued a statement to this end that the FDA has not yet approved the use of ivermectin for the treatment or prevention of new coronary pneumonia. Taking this drug in large doses is dangerous and may cause serious harm.
  [Rumor] Can you get AIDS just by being pierced?
  [Fact] The infection probability of needle stick injuries is only 0.3%.
  Recently, two Guangzhou netizens have posted on the Internet that they were stabbed with a needle in a shopping mall in Tianhe. They were worried about contracting AIDS, so they went to the hospital for examination and took AIDS. Blocking medicine. As early as 20 years ago, there were reports of similar “AIDS injection” incidents in our country. Recently, with this incident, news about “a single injection can catch AIDS” began to go viral on the Internet, creating tension.
  ”Generally speaking, the virus does not survive for a long time after leaving the human body. Studies have shown that when the HIV virus cultivated in the laboratory is exposed to the air, it loses 90% to 99% of its infectivity within a few hours.” According to Ma Ping, chief physician of the Department of Infectious Diseases, Tianjin Second People’s Hospital, there is almost no risk for people to come into contact with dry blood, semen or other body fluids that contain HIV. The moment the needle pierces a person, the blood it carries is very small, and the virus content is even less, and a small amount of blood is very easy to coagulate in the air and lose its infectivity.
  A large number of studies have shown that among the various behaviors that lead to the spread of AIDS, the probability of infection from a needle stick injury is about 0.3% (the probability of a solid needle is even lower).
  So, what should we do if we are unfortunately stabbed in the street by needles?
  Ma Ping said that in this situation, firstly, immediately squeeze around the wound (but remember not to use too much force) to squeeze out the blood as much as possible; secondly, rinse the wound with clean water; and finally, use iodine and alcohol to give Disinfect the wound.
  ”Although the possibility of being infected with AIDS by needle sticks in public is not high, you should consult a professional doctor if you need to take blocking drugs.” Ma Ping reminded that if you are injured by needles of unknown origin, or if you are infected with HIV Those with unknown infection status and high-risk sexual behavior must take the blocking drug within 72 hours, and the earlier the drug is taken, the better the blocking effect. It is best not to exceed 24 hours (2 hours is better). In addition, once the medicine is taken, it must be taken continuously for 28 days.

  [Rumor] Chills because of his “fear of cold physique”?
  [Fact] Fear of cold is related
  to metabolic rate  The weather turns cold, and people start to add clothes. But at the same temperature, some people think it’s okay to wear a windbreaker, and some people have to wear a down jacket before they dare to go out. People’s perception of “cold” seems to be different, so it is spread that some people are afraid of the cold because of the cold. The term “fear of cold physique”.
  ”There is no such thing as a’fear of cold constitution’ in medicine.” According to Zhou Shengyuan, director and deputy chief physician of the Prevention and Treatment Center of the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, TCM says that “frigidity” mostly refers to the body being attacked by external cold pathogens. , And has nothing to do with “fear of cold constitution”.
  Western medicine believes that some people’s fear of cold is related to the rate of body metabolism. People with slow metabolism and low basal metabolic rate are more likely to feel cold, such as young women who lack exercise, the elderly, and patients with certain diseases (such as hypothyroidism); conversely, people with fast metabolism and high basal metabolic rate , Can effectively resist the cold.
  So, how do these people who are afraid of the cold spend the winter?
  Zhou Shengyuan suggested that from the perspective of Chinese medicine, these people should pay attention to the following aspects in their daily nursing care: First, in their diet, eat more warm and warm foods, and eat less raw, cold, and cold foods, such as watermelon, Cucumbers, lotus roots, pears, etc.; secondly, it is necessary to strengthen physical exercises and choose sports that suit them. For example, the infirm can choose yoga, Tai Chi, Wu Qin Xi and other activities; again, to avoid exposure to wind, cold, dampness and evil, daily life needs to be regular. Quit smoking and alcohol, soothe your emotions, and less worry. Finally, moxibustion with moxa sticks, Guanyuan, Zhongwan, and Zusanli can be used to warm the spleen and kidney and strengthen the body.
  [Rumor] Rolling with foam roller can thin the calf?
  [Fact] The foam roller is just a relaxing tool
  Nowadays, there are more and more people doing exercises, and many people like to use foam rollers to relax their muscles after exercise. Recently, there have been rumors on the Internet that the foam roller has added a new skill-thin legs. Many people also show their opinions about this, saying that after using the foam roller, the whole leg has lost a circle, and not only the thin legs, some people even rely on it to thin back and thin waist…

  Tan Sijie, a professor in the Department of Sports and Human Sciences of Tianjin Institute of Physical Education, said that many people feel that foam rollers can thin legs, but it is actually a combined effect of exercise and relaxation. What really makes people thin legs is exercise, not foam rollers.
  ”The foam roller is a solid or hollow cylindrical roller made of specific materials. Its main function is to relax the muscles.” Tan Sijie said that after high-intensity exercise, the muscles will become tense. Rolling the foam roller can make the muscles and fascia Get soothing, through the combination of active exercise and passive massage, tense muscles can be stretched. At the same time, the rolled foam roller can also promote blood circulation in the human body.
  ”From a theoretical point of view, rolling a foam roller is no different from massaging. Massage cannot reduce the muscles, fat, and moisture in the calf area, and the same is true for rolling foam rollers.” Tan Sijie said, but after rolling the foam roller , You can lengthen the muscles that continue to be tense, and visually you will temporarily feel that the leg circumference becomes smaller. However, this is the same as the stretch and thinness of the rubber band, which will soon return to its original state.
  ”Therefore, it is impossible to’lie flat’ to massage the stovepipe only with a foam roller.” Tan Sijie emphasized.

  [Rumor] Nitroglycerin can relieve acute myocardial infarction.
  [Fact] Its main role is to dilate the coronary arteries. The
  heart attack is not treated in time, and tragedies caused by it happen from time to time. Nitroglycerin is often regarded as a life-saving artifact, in many people’s lives. In cognition, when an acute myocardial infarction occurs, taking a pill of nitroglycerin can save lives. Therefore, for many heart disease patients, nitroglycerin is an essential medicine around them. Can it alleviate the acute myocardial infarction?
  ”Nitroglycerin is a type of drug commonly used in patients with coronary heart disease. Its main function is to dilate the coronary arteries and reduce the preload of the patient’s heart. This can effectively relieve the symptoms of angina. But if the patient has a myocardial infarction, it means that the blood vessels are complete. At the time of occlusion, nitroglycerin cannot be relieved. Moreover, patients with myocardial infarction in the inferior or posterior wall often have symptoms such as hypotension and shock. If nitroglycerin is taken at this time, blood pressure will be further reduced, but it will not alleviate the disease. On the contrary, it will also lead to a serious risk of shock or sudden death in patients.” He Xiaonan, chief physician of the Emergency and Critical Care Center of Beijing Anzhen Hospital, Capital Medical University, emphasized.
  Gao Qiu, deputy chief physician of the Yixing People’s Hospital, also said that when myocardial infarction is used with nitroglycerin, it cannot relieve pain symptoms. Nitroglycerin can only relieve the pain caused by angina pectoris. Its function is mainly to expand the narrow coronary blood vessels and increase the blood supply to the heart. Myocardial infarction is caused by the complete blockage of the blood vessels. The use of nitroglycerin can not recanalize the blood vessels, so it cannot improve the pain symptoms caused by cardiac ischemia. For the treatment of acute myocardial infarction, early thrombolytic therapy or interventional stent therapy should be performed. If myocardial necrosis has been missed for recanalization, symptomatic and supportive treatment should be performed.
  Li Yan, deputy chief physician of the Department of Cardiovascular Medicine, Dongfang Hospital, Beijing University of Traditional Chinese Medicine, believes that when myocardial infarction occurs, the myocardium is very severely damaged, and the activity of the heart is very unstable, the heart rhythm may be arrhythmia, and the blood pressure may also be very high. In particular, patients with acute inferior myocardial infarction are prone to hypotension and slow heart rate.
  ”The patient’s blood pressure itself is low, and nitroglycerin is a vasodilator, which will cause the blood pressure to drop further. The patient will have serious consequences after taking nitroglycerin. This situation should be avoided as much as possible. Nitroglycerin is not completely inedible. It is necessary to understand the patient’s blood pressure before judging whether to eat.” Li Yan said.
