肠道微生态是由人体肠道中的菌群与宿主细胞之间的相互作用构成的统一体。近年来研究发现,肠道微生态的破坏与多种肝病的发生有关。当肠道微生态发生变化时,一方面,肠道内多数优势菌被抑制,少数菌种过量繁殖,进而出现肠道菌群失调;另一方面,肠道屏障功能受损,导致肠道细菌及其代谢产物移位和内毒素血症,进一步加重机体损害,出现 Intestinal microecology is the unity of the interaction between the bacterial population in the gut of the human body and host cells. In recent years, studies have found that the destruction of intestinal microflora and a variety of liver disease. When the intestinal microflora changes, on the one hand, the majority of dominant intestinal bacteria were inhibited, a small number of species over-breeding, and then intestinal flora; the other hand, impaired intestinal barrier function, resulting in intestinal bacteria and Metabolite displacement and endotoxemia, further aggravating the body damage occurs
