肝脏缺血再灌注损伤(Hepatic ischemia reper-fusioninjury,HIRI)可分为热缺血和冷保存缺血再灌注损伤。热缺血再灌注损伤与上消化道大出血、肝切除、肝移植等普遍相关;冷保存再灌注损伤发生在器官移植前的冷保存过程中,其发生机制与热HIRI相似。目前,对HIRI机制的研究成为学者 Hepatic ischemia reper-fusioninjury (HIRI) can be divided into hot ischemia and cold preservation ischemia reperfusion injury. Hot ischaemia reperfusion injury and upper gastrointestinal hemorrhage, liver resection, liver transplantation is generally related to cold preservation and reperfusion injury occurs in cold preservation before organ transplantation, its mechanism of occurrence and thermal HIRI similar. At present, the research on HIRI mechanism becomes a scholar
