摘要: 目的 探讨消退素D1(resolvin D1, RvD1)对大鼠肝缺血再灌注损伤(ischemia reperfusion injury, IRI)的作用。方法 实验动物随机分为假手术组(Sham组)、 IR组、RvD1组和ZnPP组。自动生化仪检测氨基转移酶水平;苏木精-伊红染色观察肝组织学变化;髓过氧化物酶(myeloperoxidase,MPO)试剂盒测定MPO水平;实时荧光定量聚合酶链反应(quantitative real-time PCR, qRT-PCR)检测细胞间黏附分子-1(intercellular adhesion molecule-1,ICAM-1)水平。结果 与IR组相比,RvD1组大鼠ALT(P<0.05)、AST(P<0.01)明显降低,肝组织IRI减轻,肝内MPO活性降低(P<0.05),ICAM-1 mRNA表达下降(P<0.05)。而ZnPP组则与RvD1组表现相反。结论 RvD1通过降低MPO活性及ICAM-1 mRNA表达发挥对大鼠肝IRI的保护作用,且可以被ZnPP所逆转。

Abstract: Objective To investigative the effect of resolvin D1(RvD1)in the rat's liver IRI and the possible mechanism. Methods SD rats were divided into 4 groups randomly: Sham group, IR group, RvD1 group(IR+RvD1)and ZnPP group(IR+ RvD1+ZnPP). The levels of ALT and AST in the serum were detected with biochemical analyzer. MPO in the rat's liver were detected with MPO kit. The changes of liver cell were observed with H-E staining. The mRNA level of ICAM-1 in rat's liver were tested with quantitative real-time PCR(qRT-PCR). Results In RvD1 group, the levels of ALT(P<0.05)and AST(P<0.01)were decreased significantly. The swellings and necrosis in the rat liver cells in RvD1 group were observed to alleviate through H-E staining. Compared with IR group, the level of MPO in RvD1 group was reduced by MPO kit. And the mRNA level of ICAM-1 in RvD1 group was measured to decrease by qRT-PCR. Conclusion RvD1 attenuates the IRI in rat's liver by reducing the level of MPO and ICAM-1 and the protective role is reversed by the inhibitor of HO-1, ZnPP.
