肠道微生物与消化系统疾病的相关性研究

摘要

肠道细菌被称为人类的长寿细菌,是一种混合的微生物在肠道内与宿主共生,在不同的身体部位、不同的个体、不同的环境因素以及随着时间变化具有差异. 这些细菌参与到机体的生理、代谢、营养、免疫等,然而肠道细菌失调和受损与某些疾病也有一定的关系,如炎症性肠病、肠易激综合征、肠道肿瘤、肥胖等. 因此,肠道细菌对于人类身体健康是极其重要的. 该文就肠道微生物与消化系统疾病的相关性研究予以综述.%The intestinal microbiota,known as the human longevity bacteria,is a group of microorganisms in intestinal symbiosis with the host.The composition of intestinal bacteria varies in different parts of the body,in different individuals,under different environmental factors and at different times.They are involved in body's physiological and metabolic,nutrition,immune process,etc.However,disorder and damage of intes-tinal bacteria also have certain relations with some diseases,such as inflammatory bowel disease and irritable bowel syndrome,intestinal cancer,obesity, etc.Therefore,the intestinal bacteria is extremely important for human health.Here is to make a review of the relationship between intestinal bacteria and digestive system diseases.
