目的:探讨归芪补肾颗粒对阿霉素导致的足细胞损伤的保护作用。方法:以0.5μg·mL-1阿霉素复制足细胞损伤模型,再分别以低、中、高剂量归芪补肾颗粒含药血清(2%,4%,8%)干预24 h后,分别检测各组细胞nephrin、p-cadherin、desmin、α-SMA mRNA(RT-PCR法)和蛋白(Western Blot法)表达。结果:RT-PCR结果显示:与空白对照组(C组)比较,阿霉素模型组(Model)nephrin、P-cadherin mRNA表达(0.342±0.140,0.094±0.012)显著降低(P=0.000),desmin、α-SMA mRNA表达(0.517±0.096,1.242±0.198)显著增高(P=0.001,0.000);与模型组比较,归芪补肾颗粒中(M-GQBS)、高剂量组(H-GQBS)nephrin、P-cadherin mRNA表达(0.536±0.086,0.254±0.060,0.546±0.113,0.274±0.069)显著降低(P=0.007,0.005,0.001,0.000),desmin、α-SMA mRNA表达(0.393±0.084,0.819±0.067,0.375±0.084,0.764±0.125)显著增高(P=0.024,0.010,0.000,0.000)中、高剂量组之间没有差异(P>0.05)。Western Blot结果显示,model组nephrin及Pcadherin蛋白含量显著降低(P=0.000),demin、α-SMA蛋白含量显著增高(P=0.000);与Model组比较,M-GQBS及HGQBS组nephrin、P-cadherin蛋白表达显著增高(P=0.002,0.003,0.005,0.002),demin、α-SMA含量显著降低(P=0.000)。结论:归芪补肾颗粒能减轻阿霉素引起的足细胞损伤,减缓足细胞上皮-间充质转分化。
