chronic gastritis is the most common type of disease in the digestive system, mainly caused byH.pyloriMost of the chronic inflammatory reactions of gastric mucosa caused by infection are pangastritis mainly in the gastric antrum, and the gastric mucosa layer is mainly infiltrated by lymphocytes and plasma cells. Some patients have atrophy and metaplasia of intrinsic glands of gastric mucosa in the later stage[
It is well known that mental and psychological factors play an important and critical role in the etiology and pathogenesis of gastrointestinal diseases, especially functional gastrointestinal disorder (FGID)[
With the development of society and medical progress, many diseases can no longer be explained by physiology. Therefore, scholars gradually shifted their attention from the disease to the patient themselves, and put forward the biological-psychological-social medical model[
FD is a common clinical functional gastrointestinal disorder (FGID). FD refers to the presence of one or more dyspeptic symptoms originating in the gastroduodenal region and the absence of any organic, systemic, or metabolic disease that can explain these symptoms. FD can be divided into postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS) according to the symptomatic characteristics. The prevalence of FD in western countries ranged from 11.5% to 14.7%[
Clinical departments often encounter such patients. They have many complaints of physical symptoms, but after various examinations, they can't find organic diseases that can explain these symptoms. Modern Western medicine describes it as medically unexplained symptom (MUS). FGID can be regarded as the MUS of gastroenterology. Biomedicine, which is dominated by science and culture, may believe that patients with MUS are not free of diseases, but they are limited to the current scientific and technological ability to fail to detect them, and the diseases behind them will definitely be found in the near future or the distant future. We should not doubt science, but must recognize the great contribution of science to medicine, and timely and actively transform and apply relevant science and technology to clinical medical practice. What we should think about is how to re-understand the multiple attributes of medicine and solve the problems that science can't solve at present more reasonably. It is obviously unreasonable to understand and treat FGID with multidimensional problems from a single dimension[
Chronic pain is clinically common, and gastroenterology is no exception. Chronic biliary tract disease is more common in patients with epigastric and right epigastric pain, among which patients with depression and anxiety often see the doctor repeatedly[
With the development of portal hypertension in hepatitis B cirrhosis, the incidence of decompensated cirrhosis increases, and the 5-year survival rate is only 14% ~28%[
acute pancreatitis (AP) is a common acute abdominal disease in clinic. Most patients' condition is self-limiting, but 20% ~30% of patients still have dangerous clinical experience, and the mortality rate is 5% ~10%[
At present, IBD is considered to be an intestinal damage caused by abnormal response of intestinal mucosal immune system, including UC and CD, which is caused by environmental, genetic, infective and immune factors. The sources of vitamin D mainly include the endogenous pathway generated by skin transformation by ultraviolet irradiation, and the exogenous pathway by ingesting foods and drugs rich in vitamin D. In addition to the traditional effects of regulating calcium and phosphorus metabolism, vitamin D has been found to have a wide range of effects on fighting infection and regulating immunity in recent years. It is related to many autoimmune diseases (such as IBD) and has attracted much attention.
Liver cancer is one of the common malignant tumors, which is a serious threat to human health[
H.pyloriInfection is an important cause of diseases such as dyspepsia, chronic gastritis, peptic ulcer, gastric cancer and gastric MALT lymphoma. In recent years,H.pyloriThe eradication rate decreased significantly, and the main reason for the eradication failure wasH.pylori is resistant to antibiotics. Therefore, the detectionH.pylori resistance, targeted selection of sensitive antibiotics is eradicatedH.pyloKey to ri. Traditional detectionH.pyloThe main method of ri resistance is drug sensitivity test, but the consumables of E-test are expensive, the paper diffusion method lacks effective judgment standard, and the agar dilution method has high requirements for operation technology; In addition,H.pyloriIt has harsh requirements for culture, slow growth under micro-aerobic conditions, and is not suitable for clinical routine development; And drug sensitivity test cannot identifyH.pyloriStrain gene mutation sites. With the development of molecular biology technology, PCR, fluorescence in situ hybridization (florescencein-situhybridization, FISH), gene chips, DNA sequencing and other molecular biology technologies have been gradually usedH.pyloriDetection of drug resistance.
