Background Renal hypertrophy has been regarded as the early feature of diabetic nephropathy （DN）, which may eventually lead to proteinuria and renal fibrosis. However, the exact mechanism of renal hypertrophy is still unclear. The aim of this study was to investigate the possible association of connective tissue growth factor （CTGF） with renal hypertrophy in uninephrectomized diabetic rats. Methods Seventy-two Sprague-Dawley （SD） rats were randomly divided into two groups： control group （group C, n=32） and diabetic nephropathy （group DN, n=40）. Each group was re-divided into 4 subgroups according to the experimental period. The rats were sacrificed at 1, 2, 4, and 8 weeks respectively after induction of diabetes. Diabetes was induced by intraperitoneal injection of streptozotocin （STZ） after rats had received uninephrectomy. Blood glucose （BG）, body weight （BW）, 24-h urinary albumin excretion （24hUalb）, kidney weight （KW）, KW/BW, glomerular tuft area （AG）, glomerular tuft volume （VG）, proximal tubular area （AT） at each time point, the width of glomerular basement membrane （GBM） and tubular basement membrane （TBM） at week 8 were measured when the rats were sacrificed. Renal expression of CTGF and p27kipl were detected by immnnohistochemical staining. The relationship between CTGF expression and increasing of VG and AT was analyzed. Results There was a significant increase of 24hUalb, KW, and KW/BW from week 1 onward in diabetic rats compared to those in group C （P〈0.05, respectively）, diabetic rats also had a significant increase of AG, VG, and AT from week 1 onward. It was also shown that diabetic rats had a thickening of GBM [（245.7±103.0） nm vs （121.8±19.1） nm, P〈0.01] and TBM [（767.7±331.1） nm vs （293.0±110.5） nm, P〈0.01] at week 8. There was a weak expression for CTGF and p27kipl in normal glomeruli and tubuli, while a significant increasing expression of CTGF and p27kipl was found in glomeruli and tubuli in diabetic kidney from week 1 onward （P〈0.05, respec

目的:观察厄贝沙坦(Irb)对大鼠糖尿病模型肾脏结缔组织生长因子(CTGF)、p27k ip1表达的影响。方法:将SD大鼠分为健康对照组(C组)、糖尿病肾病组(DN组)和糖尿病肾病Irb治疗组(DNI组),DN组和DNI组大鼠制成糖尿病模型,DNI组予以50 ***-1伊贝沙坦灌胃。各组大鼠再分为4个亚组,分别于成模后1、2、4、8周时处死,观察各组大鼠的血糖、体重、24 h尿白蛋白、内生肌酐清除率(Ccr)、肾重、肾脏肥大指数、肾小球面积(AG)和体积(VG)、肾小管面积(AT)、肾小球基底膜(GBM)厚度、肾小管基底膜(TBM)厚度的改变,通过免疫组化观察肾CTGF和p27k ip1的表达。结果:DN组和DNI组大鼠血糖较C组明显升高且维持在一个较高水平(P<0.01)。C组体重增长迅速,DN组和DNI组大鼠体重增长缓慢(P<0.01)。DN组大鼠的24 h尿白蛋白、Ccr、肾重、肾脏肥大指数、AT和VG在糖尿病早期即呈时间依赖性增加(P<0.01或P<0.05)。免疫组化半定量分析显示,各期DN组大鼠肾小球和肾小管的CTGF、p27k ip1表达均高于C组(P<0.01或P<0.05)。8周时DN组大鼠GBM和TBM均较C组明显增厚(P<0.01),而Irb可显著抑制上述参数的增加。CTGF与p27k ip1的表达、24 h尿白蛋白、AT、AG、VG呈显著正相关关系(P<0.05)。结论:早期应用Irb可抑制糖尿病大鼠早期肾脏肥大和CT-GF与p27k ip1的表达,此为早期使用该药预防DN肾脏肥大的发生提供了新的理论依据。
