| 摘 要： | 目的:在前期发现制大黄-川芎药对能抑制对比剂肾病(contrast-induced nephropathy,CIN)大鼠肾小管上皮细胞凋亡的基础上,进一步从核因子E2相关因子/血红素加氧酶-1(Nrf2/HO-1)通路探讨该药对的作用机制。方法:将32只雄性SD大鼠分为正常组(A组)、模型组(B组)、药对组(C组)、N-乙酰半胱氨酸(NAC)组(D组)。C组于造模前7 d每日灌胃制大黄-川芎水煎液,D组造模前3 d每日腹腔注射NAC(150μg/g)。B、C、D三组按照文献方法制备CIN模型。造模后24 h处死动物,并腹主动脉采取血测定血清肌酐(Scr)、尿素氮(BUN);代谢笼收集24 h尿液,并测定尿液中急性肾损伤(AKI)标志物N-乙酰-β-D氨基葡萄糖苷酶(NAG)、γ-谷氨酰转肽酶(U-γ-GT);分别提取肾组织中核蛋白和总蛋白,采用Western blotting方法检测肾组织中Nrf2和HO-1蛋白表达。结果:与A组比较,B组大鼠Scr、BUN、尿NAG、U-γ-GT均明显升高(P0.01),肾组织中Nrf2、HO-1蛋白表达明显上调(P0.01);与B组比较,C、D组Scr、BUN明显降低(P0.05),尿NAG、U-γ-GT显著降低(P0.01),Nrf2、HO-1蛋白表达显著降低(P0.01)。结论:Nrf2/HO-1通路活化参与了CIN大鼠急性肾损伤过程,且制大黄-川芎药对可通过抑制该通路活化保护CIN大鼠肾功能。
