摘要:

【摘要】 目的  观察补肾活血方治疗对阿霉素(ADR)诱导的阿霉素肾病小鼠肾小球足细胞裂孔膜蛋白nephrin表达的影响,并探讨其作用机制。方法  用ADR诱导产生局灶性节段性肾小球硬化(FSGS)肾病模型,1周后用补肾活血方治疗(治疗组),持续6周。并设空白对照组、模型组。收集各组血、尿及肾组织,检测其体质量、右肾质量、血清白蛋白(ALB)、尿白蛋白/尿肌酐比值(UACR)。光镜观察肾组织形态改变;免疫荧光测定小鼠肾小球足细胞nephrin的表达;RT-PCR检测各组肾组织nephrin mRNA的表达。结果  模型组UACR显著高于对照组与治疗组,体质量和ALB显著低于对照组和治疗组(均P<0.01);对照组肾小球足细胞nephrin免疫荧光呈连续性表达,治疗组呈轻微缺失,模型组呈少量点状或片状表达,较对照组和治疗组表达强度明显减少。模型组nephrin mRNA表达水平均显著低于对照组和治疗组(P<0.01)。结论  补肾活血方能减少阿霉素肾病小鼠的蛋白尿,可能与改善肾小球足细胞nephrin的表达减少有关。

Abstract: Objective  To investigate the effect of nourishing kidney and activating blood recipe of traditional Chinese medicine on the expression of Nephrin in renal tissue of mice with adriamycin nephropathy(ADRN) induced by adriamycin(ADR) Methods  The focal segmental glomerulosclerosis( FSGS) change of nephropathy model was induced by injection of adriamycin into the tail vein.After 1 week,Twenty four male rats were randomly divided into normal control group,ADR model group and treatment group.The level of body weight,right renal weight and urinary albumin creatinine ratio (UACR) were measured,Furthermore, the morphological changes of renal tissue were observed under microscope.The mRNA and protein expressions of Nephrin in renal tissues were determined by RT-PCR and immunofluorescence respectively. Results  There was a significantly higher level of body weight and lower level of UACR in normal control group and treatment group than that of ADR model group (P < 0.05). There were intensy expression of Nephrin in glomerular mesangial region in normal control group and treatment group compared with in ADR model group.There were significantly higher expressions of Nephrin mRNA in those of normal control group and treatment group than in ADR model group .(P <0.05) There were no significant differences in Nephrin mRNA between normal control group and treatment group( P>0.05)Conclusion  The method of nourishing kidney and activating blood recipe of traditional Chinese medicine attenuates Nephrin decrease in FSGS change nephropathy model which is closely related with the reduction of proteinuria.
