肠道黏膜屏障与慢加急性肝衰竭的关系研究进展

Research progress on the relationship between intestinal mucosal barrier and acute-on-chronic liver failure

胃肠道是一个极其复杂的生态系统,健康完整的肠道黏膜屏障是阻止有害物质易位的基本防线。慢加急性肝衰竭(ACLF)时肠道黏膜屏障功能受损,同时由于肠道微生态失调,导致细菌移位和内毒素血症,进一步加重ACLF病情。维护肠道黏膜屏障的正常功能,对ACLF的治疗有重要意义。本文就正常肠道黏膜屏障功能、肠道黏膜屏障受损与ACLF的关系以及受损后对ACLF病程的影响进行综述。

The gastrointestinal tract is an extremely complex ecosystem,and a healthy and intact intestinal mucosal barrier is the basic defense against the translocation of harmful substances.The impaired function of the intestinal barrier in acute-on-chronic liver failure(ACLF)is further aggravated by the dysregulation of intestinal microecology,which leads to bacterial translocation and endotoxemia.Maintaining the normal function of the intestinal mucosal barrier is important for the treatment of ACLF.This paper reviews the function of the normal intestinal mucosal barrier,the relationship between the damaged intestinal barrier and ACLF,and the impact of the damaged intestinal barrier on ACLF progression.
