Gut-derived-infection and biological behavior of intestinal bacteria / 肠外与肠内营养

ABSTRACT

Currently,the popular notions on the mechanisms of gut-derived-infection are described as follows.The stress may cause the damage of intestinal mucosal barrier and dysfunction of intestinal immune response,which leads to the alteration of intestinal flora,abnormal proliferation of opportunistic pathogen as well as the translocation of alive bacteria and their toxin into systemic compartment.As a result,the proinflammatory cytokines are released to induce the outbreak of intestinal inflammation or systemic inflammatory response syndrome,even the MODS.This review focuses on the relationship between biological behavior of intestinal bacteria and gut-derived-infection.
