[Role of hydrogen sulfide mediated autophagy related genes in intestinal function injury of sepsis].

Sepsis is an organ dysfunction that endangers a patient's life caused by an imbalanced infection response, and is a clinically critical illness. Despite a deep understanding of the pathogenesis of sepsis, there has been no significant improvement in sepsis mortality during clinical treatment at home and abroad. In recent years, the role of autophagy in the pathogenesis of sepsis has become a new research point in the field of medical research. Autophagy may protect the body by removing pathogenic microorganisms, neutralizing microbial toxins, and regulating cytokine release in sepsis. Studies have shown that autophagy plays a role in heart and lung organ dysfunction and inflammatory immune response in sepsis. Studies have also shown that hydrogen sulphide (H2S) can activate autophagy through multiple signaling pathways, such as adenylate-activated protein kinase/mammalian target of rapamycin (AMPK/mTOR), phosphoinositide 3 kinase/Akt/mTOR (PI3K/Akt/mTOR), liver kinase B1/STE20 related adapter protein/mouse protein 25 (LKB1/STRAD/MO25) and microRNA-30c (miR-30c), etc. signaling pathways. This article reviewed the effects of H2S on autophagy-related genes Beclin-1 and microtubule-associated protein light 3 chain (LC3) on intestinal function of sepsis in order to explore the H2S-mediated autophagy gene expression in pus. The protective role of autophagy gene for intestinal dysfunction provides a new strategy for the treatment of sepsis in the future.
