"Pylorus Weidun, a national patented strain; preventing gastric cancer and never halitosis; available for pregnant women, medical grade..." recently, some illegal businesses hyped that "anti secluded toothpaste" could kill Helicobacter pylori and prevent gastric cancer, and sold the so-called "anti secluded toothpaste" on the e-commerce platform. What is Helicobacter pylori? Why are they called "ghosts" in the stomach? Why can't "kangyou toothpaste" prevent Helicobacter pylori infection? How to prevent, detect and treat Helicobacter pylori infection? Medical experts from Peking Union Medical College Hospital, Cancer Hospital of Chinese Academy of Medical Sciences and other institutions gave authoritative answers. What is Helicobacter pylori? What are the main hazards? Helicobacter pylori is a kind of micro aerobic gram-negative bacillus, which is spiral. It is a bacterium that can colonize the human stomach for a long time and cause chronic inflammation. It can be transmitted through mouth and fecal mouth. How harmful is Helicobacter pylori infection? Yan Xuemin, chief physician of gastroenterology department of Peking Union Medical College Hospital, introduced that Helicobacter pylori infection is not only the main cause of gastritis and peptic ulcer, but also a high-risk factor of gastric cancer. Yan Xuemin said that most people infected with Helicobacter pylori have no symptoms and complications, but almost all have chronic active gastritis. About 15% to 20% of the infected people have peptic ulcer, 5% to 10% have dyspepsia and about 1% have gastric malignant tumor. Helicobacter pylori infection is also an important pathogenic factor of gastroduodenal ulcer, which is closely related to the occurrence of gastric cancer and gastric mucosa associated lymphoid tissue lymphoma. According to the report of the World Health Organization, the risk of gastric cancer in patients with Helicobacter pylori infection can be increased by two to three times. In developing countries, about 63% of gastric cancer cases are related to Helicobacter pylori infection. In addition, the "combat effectiveness" of Helicobacter pylori is also very strong. In addition to the gastric mucosa, Helicobacter pylori is found in human saliva, dental plaque and feces. Why can't "kangyou toothpaste" prevent Helicobacter pylori infection? "Helicobacter pylori colonizes in the stomach" is the scientific characteristic of the bacterium. Therefore, there is no scientific basis for relying on the oral cleaning link of toothpaste brushing to prevent or treat Helicobacter pylori infection. The "scientific rumor refutation platform" sponsored by China Association for science and technology and other departments once published the article "can HP be killed with" Helicobacter pylori toothpaste? It's a little beautiful to think "to refute popular science rumors. Based on this scientific understanding of Helicobacter pylori, it is easy to identify the false propaganda of "anti secluded toothpaste". Illegal businesses often use consumers' fear of gastric cancer to promote goods with false efficacy publicity. Article 17 of the advertising law stipulates that, except for the advertisements of medical treatment, drugs and medical devices, any other advertisements involving the function of disease treatment shall be prohibited, and medical terms or terms that are easy to confuse the marketed goods with drugs and medical devices shall not be used. In order to evade supervision, some "anti secluded toothpaste" packages were marked with "mechanical size" and "elimination size", and the batch number was advertised. In fact, "Xiaozi number" refers to the sanitary batch number approved by the local health department, which does not have any curative effect and belongs to the category of sanitary disinfection; "Xizi No." refers to the filing no. of medical devices. Xizi No. products are medical devices with low risk and the implementation of national routine management can ensure their safety and effectiveness. Generally speaking, toothpaste is a "makeup brand". These batches do not prove that the toothpaste itself has the effect of preventing and treating Helicobacter pylori infection. How to prevent, detect and treat "Helicobacter pylori" infection? Experts said that the high infection rate of Helicobacter pylori in China may be related to the habit of eating together. Disinfection of tableware, public chopsticks and serving of individual dishes are the most effective ways to prevent H. pylori infection. The situation of "one person gets sick and the whole family is infected" of Helicobacter pylori infection in China is not uncommon, mainly because the family sharing meal system makes Helicobacter pylori infect through saliva. When eating with chopsticks, it will also increase the infection risk of diners, and children and the elderly are more likely to be infected. In addition, the occurrence and development of the disease is also related to many other factors, such as eating habits, living habits, genetic factors and so on. Experts from the Cancer Hospital of the Chinese Academy of Medical Sciences suggest that if you want to test whether you are infected with Helicobacter pylori, it is recommended to test the fecal Helicobacter pylori antigen in a regular hospital, followed by the C-13 urea breath test. If gastroscopy is performed, the presence of Helicobacter pylori infection can be detected by rapid urease detection, and gastritis, gastric ulcer and gastric cancer can be observed. Experts say that even if the infection is confirmed, patients do not need to be too nervous. The vast majority of people can achieve bacterial eradication through oral drug treatment within two weeks. Li Jing, chief physician of the Department of health medicine of Peking Union Medical College Hospital, suggested that people with gastric diseases must be treated with sterilization. Four combination therapy is commonly used, that is, taking two antibiotics, bismuth and acid inhibitor for about two weeks. Li Jing reminded that there must be evidence of current infection before deciding on treatment. There are also views in the medical community that Helicobacter pylori does not necessarily need to be eradicated. It is recommended that patients and doctors decide after discussing their own indications. (outlook new era)
