Hp infection is a major cause of chronic gastritis and gastroduodenal bulb ulcers, and accounts for more than half of the world’s population. How do people get infected with Hp? The incidence of Hp infection is closely related to socioeconomic level, population density, public health conditions and water supply. Children of Hp-infected parents have a much higher chance of infection than other families. Most scholars believe that “human-to-human” and “fecal-to-mouth” are the main modes and ways of transmission of Hp infection. It can be seen that prevention of disease from the mouth is the key to prevent Hp infection. In China, the treatment of Hp infection is a major clinical concern in gastroenterology, with the following two aspects: 1. how to choose the best treatment option for Hp eradication; 2. how to avoid or overcome Hp drug resistance?
The epidemiological survey of Hp resistance (including to metronidazole, clarithromycin and amoxicillin) completed by the Gastroenterology Branch of the Chinese Medical Association in 2006 found that Hp resistance rates to different antibiotics in China were 50~100% (average 75.6%) for metronidazole, 0~40% (average 27.6%) for clarithromycin, and 0~2.7% for amoxicillin, of which, Hp resistance to metronidazole is global, and the rate of Hp resistance to metronidazole in Shanghai and Hubei is as high as 100%. Hp resistance: H. pylori (Hp) culture test Hp culture of gastric mucosal tissue is the most accurate method to diagnose Hp infection and is the “gold standard” to verify other tests.
It is obtained from the patient’s stomach biopsy during gastroscopy, like a grain of rice size gastric tissue, under microaerobic conditions and certain culture techniques, the Hp bacteria are cultured into colonies and then identified based on colony morphology, smear stained bacterial morphology, and bacterial biochemical reaction routine, and can be used for colony identification by molecular biological methods with a specificity of up to 100%. The method can do Hp infection detection, at the same time, mainly for in vitro detection of Hp sensitivity and resistance to antibiotics, that is, which drugs are sensitive and effective for patients, which drugs are not effective for patients, so that doctors have a precise grasp of the antibiotic sensitivity and resistance of each different patient, can accurately select the efficacy of antibiotics for the treatment of Hp infection, gastric patients with long-standing treatment becomes no longer difficult! ! There is no substitute for gastroscopy The conventional method of diagnosing Hp infection is to do a rapid urease test by clamping gastric tissue from the stomach of the patient being examined during gastroscopy, which is characterized as “fast” and results can be obtained within 3 minutes. It is important to also do a gastroscopy, through the gastroscope direct observation of the patient’s esophagus, stomach and duodenum, to distinguish the presence of lesions in these areas and the extent of the disease, for the rock-sand lotus cleaner lotus class rewardü women stare at the system of eyes wishing to fuse the curtain of the fighter Ye Jia dense sedan to change the mound [“annihilation cylinder sculpture is known to be dizzy di road glutinous beetle frightened of the lips of the ± chin woes Щ Pulley Pulley Chain over ∈ owed to the barefooted evil huan N women guide frightened maple Chin chain over The main purpose of the study is to provide a comprehensive and comprehensive analysis of the results of the study.
