摘要 目的探讨辛伐他汀(simvastatin)对糖尿病鼠肾nephrin基因表达的影响。方法以STZ诱导大鼠发生糖尿病(DM),以辛伐他汀灌胃,不同病程取标本测定尿白蛋白排泄率(UAE)、尿β2-微球蛋白(β2-MG)排泄率,测定血浆胆固醇浓度,以免疫组化及荧光定量RT-PCR法定性及定量测定肾脏nephrin mRNA的表达。结果DM非治疗组UAE及β2-MG排泄率高于对照组,而辛伐他汀治疗组则明显低于DM 8周非治疗组;DM 8周非治疗组nephrin mRNA的表达量较正常对照组及辛伐他汀治疗组明显减少。结论DM大鼠UAE及尿β2-MG排泄率均明显升高,辛伐他汀可阻断这一改变;DM大鼠nephrin mRNA的表达量逐渐减少,辛伐他汀可能通过降低DM大鼠血浆胆固醇浓度影响nephrin mRNA的表达进而减少UAE。
