On March 16, at the second "315+E" cloud anti-counterfeiting health science evening hosted by China Family Newspaper and others, Ge Junbo, academician of the Chinese Academy of Sciences, Tan Xianjie, chief physician of the Department of Obstetrics and Gynecology of Peking Union Medical College Hospital, and Liu Guangzhen, president of Shanxi Provincial Hospital of Traditional Chinese Medicine Waiting for more than ten authoritative experts to crack down on fake health rumors.
Rumor 1: When a woman comes to menstruation, her body is detoxifying
Tan Xianjie, chief physician of the Department of Obstetrics and Gynecology, Peking Union Medical College Hospital: Menstruation is not a detoxification, too much or too little is not good
Menstruation is not a detoxification, it is a physiological phenomenon unique to women, and a sign that women have normal reproductive capacity.
In addition to blood, menstrual blood components are mainly endometrial fragments, cervical mucus and vaginal epithelial cells, which are the metabolism of normal human cells and are non-toxic.
The amount of normal menstruation is about 50 ml. More than 80 ml is excessive menstrual flow, and less than 20 ml is excessive menstrual flow. Excessive menstruation is not only a sign of smooth detoxification, but may be an early warning of certain diseases, such as endometrial polyps, endometrial cancer, and endometrial fibroids. Menorrhagia does not mean poor detoxification. There may be some endocrine diseases, such as polycystic ovary syndrome, endometrial adhesions after uterine surgery, and cervical canal adhesions.
Rumor 2: Cracked heel is a lack of vitamins or collagen
Xinghua, deputy dean and director of the Department of Dermatology of the First Clinical College of China Medical University: lack of vitamins is bad for the body, but it has nothing to do with heel cracks.
Cracked heel is a skin disease, the scientific name is chapped skin. The common cause is the lack of moisture due to the dry environment, which causes cracks under the action of external force. At the same time, some are related to diseases, such as hand eczema, athlete's foot, diabetes, and improper skin care such as excessive use of alkaline substances, excessive friction stimulation, excessive walking, etc.
Vitamins are trace elements necessary for the functioning of the body, but under normal circumstances, it is difficult to see the cracking caused by vitamin deficiency, and the cracking caused by collagen has no scientific basis.
For heel cracks, there are many prevention and treatment measures. For example, antifungal drugs can be used to treat tinea pedis caused by fungal infections, and moisturizing skin care products can be used to treat dry skin.
Rumor 3: 20% of blood vessels are blocked without feeling, 40% are easy to get tired, and 50% will have high blood pressure
Pan Junjie, deputy chief physician of the Department of Cardiology, Huashan Hospital Affiliated to Fudan University: The main purpose of these statements is to sell their own products.
It is right that 20% have no symptoms, but more than 50% of the blood vessels are blocked before they have related symptoms, and some people even have no symptoms when more than 70%-80% of the blood vessels are blocked.
Should be screened according to their own conditions in time to see if the blood vessels are blocked. At the same time, a good lifestyle should be maintained, such as a light diet, regular exercise, smoking cessation, and control of blood pressure, blood sugar, blood lipids, etc. If there is a problem, regular medication should be taken according to the doctor's opinion.
The main purpose of rumors is to sell products, and their claims are unfounded. It is right for 20% to have no symptoms, but it is wrong to say that 50% have high blood pressure. High blood pressure is the cause rather than the result.
Rumor 4: Hold your breath for 30 seconds to test whether your lungs are healthy
Feng Jing, Chief Physician of the Department of Respiratory and Critical Care Medicine, Tianjin Medical University General Hospital: There is no necessary connection
Whether you can hold your breath for 30 seconds has nothing to do with lung health. The reason why the masses agree with this rumor to a certain extent is based on their subjective feelings. Some patients with lung diseases may feel suffocated or can’t hold their breath for a long time due to shortness of breath.
The lungs are composed of many alveoli. The examination mainly includes the morphology of the lungs and chest expansion, pulmonary function and pulmonary blood vessels. The morphological examination of the lungs and chest expansion can confirm whether there are tumors, malformations, pneumonia, tuberculosis and other diseases in the lungs of the patient, as well as other diseases that may cause changes in the morphology of the lungs. The main examinations are chest plain CT and enhanced CT .
There are also some tests that are easily overlooked by patients and certain doctors. They are tests for pulmonary vascular diseases, including pulmonary embolism, pulmonary venous obstructive diseases, vasculitis, and other pulmonary vascular diseases. When the patient has respiratory symptoms or other discomforts, the above corresponding examinations should be carried out according to the patient's situation to clarify the specific situation of the patient, and the rumor that the lung disease can be checked by holding your breath for 30 seconds should not be credulous.
Rumor 5: Lying down immediately after a meal or loosening the waistband can cause gastroptosis
Kuai Xiaoling, chief physician of the Department of Gastroenterology, Nantong University Affiliated Hospital: If you don't loose your belt after a meal, it inhibits gastrointestinal peristalsis.
When the stomach reaches below the belly button, which is the pelvic cavity, we think it is gastroptosis. The stomach is fixed in the abdominal cavity by multiple ligaments, which are like rubber bands to firmly fix the stomach in the abdominal cavity. Overeating, weight loss, and decreased intra-abdominal pressure can easily cause gastroptosis.
In fact, lying down immediately after a meal will cause gastroesophageal reflux disease instead of gastroptosis. If you wear a belt after a meal, not only can you not support the stomach, but it also inhibits the expansion of the stomach and the peristalsis of the intestines.
Rumor 6: Scientists have found that drinking yogurt can prevent cancer
Nutritionist Liu Yuan, deputy director of the Department of Clinical Nutrition, West China Hospital of Sichuan University: First of all, we must ensure that we use qualified yogurt
Deng Zhenhua’s team from Sichuan University analyzed 61 domestic and foreign related yogurt and cancer prevention. The results found that fermented dairy products really help prevent cancer, especially yogurt. Yogurt contains probiotics, which has an immune-regulating effect, can improve immunity and prevent cancer.
However, there are many kinds of yogurt on the market, and the quality is different. According to national standards, every 100 ml of yogurt contains more than 2.3 grams of protein to qualify as yogurt. If it is less than 2.3 grams and very dilute, then it is likely to be a lactic acid bacteria drink.
Therefore, to drink yogurt to prevent cancer, we must first ensure that we choose qualified yogurt, and that the probiotic bacteria and protein content are in line with national standards in order to achieve the purpose of cancer prevention.
Rumor 7: Eating fruit at night is easy to get diabetes
Deng Deqiang, deputy dean and chief physician of Urumqi Hospital of Traditional Chinese Medicine: There is no direct relationship, but these groups of people should pay attention to
Diabetes is a disease where genetics and environment work together. The increase in blood sugar is mainly due to the intake of too many calories, and the fruit itself does not contain many calories. As long as the fruit is eaten normally, it is helpful to the body. There is no saying that eating fruit at night will cause diabetes.
However, patients with obesity, hyperlipidemia, high blood pressure, and even cardiovascular and cerebrovascular diseases must pay attention to the intake of fruits.
Rumor 8: Washing hair with aspirin can reduce dandruff and gray hair
Xue Siliang, deputy chief physician of the Department of Dermatology, West China Hospital, Sichuan University: Acetylsalicylic acid is not equal to salicylic acid
The generation of dandruff is divided into physiological and pathological. Physiological is the normal shedding of skin. Pathological dandruff such as seborrheic dermatitis, fungal infection and psoriasis requires symptomatic treatment. Gray hair is also divided into physiological and pathological. Pathological treatments are required. Physiology is caused by the reduction of pigment cells in hair follicles or deep pigmentation. So far, there is no effective treatment method.
The chemical name of aspirin is acetylsalicylic acid, which is different from the salicylic acid contained in some anti-dandruff shampoos on the market. There is no scientific basis for washing hair with aspirin, and it is nonsense to solve the problem of gray hair. .
Rumor 9: Eating dandelion can cure thyroid tumors
Liu Guangzhen, Dean of Shanxi Provincial Hospital of Traditional Chinese Medicine: There is insufficient evidence
Dandelion is a commonly used traditional Chinese medicine, and its main functions are to clear away heat, detoxify, and dispel blood.
At present, there is no more clinical evidence that dandelion can inhibit cancer, or can inhibit tumor cells, or can have a good effect in the treatment of cancer. It can be said that the evidence that dandelion is used to treat thyroid adenoma and treat thyroid cancer is still insufficient.
Rumor 10: Heart stent surgery is "ineffective medical treatment"
Ge Junbo, academician of the Chinese Academy of Sciences and director of the Department of Cardiology, Zhongshan Hospital Affiliated to Fudan University: Placing a stent is not a fundamental solution, but keeping blood vessels open is the goal
The essence of the stent is a stainless steel shelf to relieve myocardial ischemia. Although the stent itself is a very thin and thin tube, it is metal, which occasionally causes restenosis of the stent in the blood vessel. From 2000 to 2001 or so, clinicians used a long period of research to do some immunosuppressive agents on the surface of the stent to inhibit the restenosis caused by the excessive proliferation of endothelial cells. This is the drug-eluting stent.
In principle, placing a stent is not the most fundamental way to solve the problem. After placing the stent, maintaining the smoothness of the blood vessel is the goal pursued. Therefore, we promote a healthy lifestyle, control high blood pressure, high blood fat, high blood sugar, so as to control the formation of restenosis or thrombosis, so that patients can return to their families and life with dignity.
