摘　　要：目的探讨四君子汤联合缺血预处理(ischemia preconditioning,IPC)对大鼠肝脏缺血再灌注损伤的保护作用及机制。方法将SD大鼠100只随机分成假手术组、空白对照组、四君子汤预处理组、IPC组、四君子汤预处理+IPC组。肝脏缺血再灌注术后检测血清天门冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT);检测肝细胞原位凋亡;检测肝组织中丙二醛(MDA)和超氧化物歧化酶(SOD)。结果四君子汤预处理+IPC组ALT和AST水平与空白对照组、四君子汤预处理组、IPC组三组比较,明显降低,差异有统计学意义(P<0.05)。四君子汤预处理组及IPC组ALT和AST水平与空白对照组比较,明显降低,差异有统计学意义(P<0.05)。四君子汤预处理组、IPC组、四君子汤预处理+IPC组三组中肝细胞凋亡指数和MDA水平均显著低于空白对照组,差异有统计学意义(P<0.05)。四君子汤预处理+IPC组中SOD水平显著高于其余四组,差异有统计学意义(P<0.05)。四君子汤预处理组、IPC组SOD水平显著高于空白对照组,差异有统计学意义(P<0.05)。结论四君子汤联合IPC,在大鼠肝脏缺血再灌注时减轻过氧化损伤,抑制细胞凋亡,从而起到保护作用。Objective To investigate the effect of Decoction of Four Mild Drugs with ischemia preconditioning against hepatic is-chemia-reperfusion in rats .Methods 100 SD rats were randomly divided into the SHAM ,the Control ,the Decoction of Four Mild Drugs , the IPC ,the Decoction of Four Mild Drugs ＋ IPC groups .After a Surgery for hepatic ischemia -reperfusion ,the levels of glutamic acid aminotransferase （ALT）;Aspartate aminotransferase （AST）;apoptosis;malondialdehyde （MDA）;superoxide dismutase（ SOD ） were mea-sured .Results ALT and AST levels in the the Decoction of Four Mild Drugs＋IPC group were significantly lower than those in the Control , the Decoction of Four Mild Drugs and the IPC groups （ P〈0.05 ） .ALT and AST levels in the Decoction of Four Mild Drugs and the IPC groups were significantly lower than that in the control group （ P〈0.05） .Apoptotic index and MDA level in the the Decoction of Four Mild Drugs＋IPC ,the Decoction of Four Mild Drugs and the IPC groups were significantly lower than that in the control group （ P〈0.05） .SOD level in the Decoction of Four Mild Drugs ＋IPC group was significantly higher than those in the other four groups （ P〈0.05 ） .SOD level in the the Decoction of Four Mild Drugs and IPC group were significantly higher than that in the control group （ P〈0 .05） .Conclusions De-coction of Four Mild Drugs combined with IPC could reduce ischemia -reperfusion injury in rats by alleviating the inflammatory reaction and anti-apoptotic effect .
