摘要肠道菌群是定植于肠道中正常的微生物群,在机体内发挥重要的生理作用,目前在消化、内分泌、神经、心血管、免疫等系统疾病中被广泛研究.文章阐述了肠道菌群在健康人体中的功能、常用的研究方法及其在风湿免疫性疾病发生发展中的作用机制,提示肠道菌群作为潜在的新靶点,将为临床诊治风湿免疫性疾病提供新的思路与方向.

abstractsGut microbiota is composed of trillions of microorganisms inhabiting in the human gastrointestinal tract,profoundly influences many aspects of host physiology.The roles of gut microbiota have been investigated extensively in the gastrointestinal,endocrine,neurological,cardiovascular and immune systems.This article reviews the recent research progress on the function of microbes in healthy organisms,the common research methods for microbiota,and the roles of microbiota in rheumatic immune diseases.It is expected that gut microbiota would be a novel target of clinical diagnosis and treatment for rheumatic immune diseases.
