摘　　要：Background:The aim of the study was to explore a feasible method for alleviating limb ischemia-reperfusion injury(LI/RI)through the use of a high-concentration citrate solution(HC-A solution)for limb perfusion(LP).Methods:Eighteen pigs were divided into three groups:the Sham group,LI/RI group,and HCA group.The Sham group underwent exposure of the iliac artery and vein.The LI/RI group underwent tourniquet placement and clamping of the iliac artery and vein to simulate LI/RI.The HCA group received HC-A solution LP for 30 min through the left iliac artery below the level of blood flow occlusion based on the LI/RI group.Oxidative stress markers and inflammatory response markers were compared among the three groups.Results:Compared to the LI/RI group,the HCA group showed significantly lower levels of serum creatine kinase(CK),lactate dehydrogenase(LDH),malondialdehyde(MDA),tumor necrosis factor-α(TNF-α),aspartate aminotransferase(AST),and ala-nine aminotransferase(ALT),and significantly greater activities of serum superoxide dismutase(SOD)(p<0.05).There were no significant differences in serum interleukin-6(IL-6)or in muscle MDA,SOD,TNF-α,and IL-6 between the HCA group and the LI/RI group(p>0.05).Compared to the LI/RI group,MDA,TNF-α,and IL-6 levels in the liver were significantly lower in the HCA group(p<0.05),while SOD activities were not significantly different(p>0.05).Histopathological examination revealed reduced skeletal muscle and liver damage in the HCA group compared to the LI/RI group.Conclusions:HC-A solution LP can alleviate liver damage caused by LI/RI in pigs.
