Objective To study the effect of massive blood transfusion program(MTP) in early massive blood transfusion and preventing coagulopathy.Methods Fifty cases of massive blood transfusion were clinically collected and performed the statistical analysis and processing before and after intervention according to the blood transfusion scheme of MTP.The statistical comparison was performed by using the data before and after intervention.Results PLT was decreased with the increase of transfusing of RBC.After transfusing 15 U of RBC,the PT test,INR and APTT were increased significant(P＜0.05).After transfusing 20 U of RBC,the Fib was decreased significant(P＜0.05).The MTP had statistical difference between before and after intervention(P＜0.01).Conclusion The MTP application has an important significance to prevent the occurrence of coagulopathy and evaluate the coagulation status.

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 (H 2S) 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 H 2S on autophagy-related genes Beclin-1 and microtubule-associated protein light 3 chain (LC3) on intestinal function of sepsis in order to explore the H 2S-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.

Sepsis is one of the main causes of death in critically ill patients. The intestinal tract is not only the organ easily involved in sepsis, but also the initial organ in the progression of sepsis, so the improvement of intestinal barrier function is the key of the treatment of sepsis. In recent years, it has been found that autophagy is involved in the pathological process of sepsis, maintaining mitochondrial function by clearing damaged organelles, inhibiting inflammation, oxidative stress and apoptosis, regulating immunity, maintaining intestinal homeostasis, and improving the condition and prognosis of sepsis. It is an effective target for the treatment of sepsis. As a new type of medical gas signal molecule, hydrogen sulfide (H 2S) can regulate autophagy by regulating multiple signal pathways, which has become a new target in the treatment of sepsis. This article reviews the signal pathway regulation mechanism of H 2S regulating autophagy in septic intestinal dysfunction.
