摘要 目的探讨阿托伐他汀钙对肺缺血再灌注损伤的保护作用及其作用机制。方法采用在体大鼠单肺原位缺血再灌注模型。30只Wistar大鼠随机分成假手术组(SO)、缺血再灌注组(IR)、阿托伐他汀钙处理组(AT),每组10只。各组进行肺湿干重比(W/D)、肺通透性指数(LPI)、脂质过氧化合物丙二醛(MDA)、超氧化物歧化酶(SOD)活性、髓过氧化物酶(MPO)活性测定,并进行肺组织光镜评价。采用免疫组织化学方法检测诱导型一氧化氮合酶(iNOS)、内皮型一氧化氮合酶(eNOS)、肺表面活性物质相关蛋白A(SPA)表达的变化。结果AT组较IR组LPI(0.023±0.003)vs(0.030±0.004)、MDA(17.685±1.537)nmol/mLvs(37.364±3.166)nmol/mL、MPO(0.052±0.002)U/mLvs(0.080±0.004)U/mL,W/D(4.650±0.114)vs(4.769±0.106)降低(P<0.05),而SOD较IR组(34.726±0.943)U/mLvs(19.728±0.817)U/mL升高(P<0.01)。AT组较IR组肺SPA表达(1996.584±260.081)vs(1119.609±348.256)、eNOS(181.933±65.715)vs(69.228±16.759)升高(P<0.01),而iNOS表达较IR组(82.294±41.150)vs(303.739±95.383)降低(P<0.01)。结论阿托伐他汀钙有保护肺缺血再灌注损伤的作用。其可能的机制为维持肺表面活性物质和内皮NO活性,减少自由基的产生及抗炎作用。
