Abstract:

目的:观察抗纤灵对小鼠慢性肾功能衰竭(CRF)模型肾组织相关炎症因子的干预作用。方法:将40只C57BL/6J小鼠随机分为假手术组、模型组、雷帕霉素组和抗纤灵组,每组10只,除假手术组仅分离肾组织外,其他各组采用Platt 5/6肾切除方法制备CRF模型,雷帕霉素组、抗纤灵组分别予雷帕霉素、抗纤灵水煎剂,假手术组及模型组予等量生理盐水灌胃,疗程8周。免疫组化法检测肾组织中F4/80细胞的表达,RT-PCR法检测肾组织基质金属蛋白酶-2(MMP-2)、基质金属蛋白酶-9(MMP-9)mRNA的表达,ELISA法检测大鼠肾组织白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)水平。结果:与假手术组比较,模型组小鼠肾组织F4/80阳性细胞,MMP-2、MMP-9mRNA水平明显升高,IL-6、TNF-α含量明显增加(P<0.01);与模型组比较,雷帕霉素、抗纤灵组F4/80阳性细胞减少,MMP-2、MMP-9mRNA水平下降,IL-6、TNF-α含量降低(P<0.05或P<0.01);雷帕霉素和抗纤灵组比较,两组无显著性差异(P>0.05)。结论:抗纤灵能够减轻CRF小鼠肾组织的炎症反应,抑制肾脏纤维化
