Multiple procedures of liver transplantation bring conditions producing cold ischemia-reperfusion (I/R) injury. During cold storage, the graft organ is subjected to cold ischemia, also known as hypoxia injury. After reperfusion, although hypoxic condition has been ameliorated, reoxygenation of the graft liver can produce not only reperfusion injury including generation of oxygen free radical, lipoperoxidation and calcium overload, but also aggravate the hypoxia damage, involving endothelial cell (EC) damage, Kupffer cell (KC) activation, and adherence of neutrophils and platelets to Ecs. Clinically, I/R injury is one of the major problems complicating liver transplantation, and can ultimately result in serious complications such as primary nonfunction and delayed graft function, which may lead to the need of urgent retransplantation. Therefore, the therapeutic strategies of attenuating graft I/R injury are clinically significant and might improve overall graft function and survival.
