目的:观察整合素连接激酶(ILK)在梗阻性肾病合并肾小管酸中毒中的表达,探讨肾小管酸中毒在致肾间质纤维化中的作用。方法实验大鼠75只,其中假手术组大鼠25只,单侧输尿管梗阻(UUO)大鼠50只。UUO大鼠于术后第7天分为肾小管酸中毒大鼠(UUO1组,n=31)和非肾小管酸中毒大鼠(UUO2组,n=19),同时做肾功能与组织学检测,于手术后7、14、21、28 d时分批处死大鼠,免疫组织化学与 Western blot法测定肾组织中 ILK的表达。结果与 UUO2组比较,UUO1组光镜下炎症细胞浸润和间质纤维化程度更严重;假手术组仅有少量的 ILK蛋白表达,几乎无纤粘连(FN)蛋白的沉积,UUO2组 ILK蛋白表达及 FN蛋白的沉积增多,而 UUO1组较 UUO2组增多。结论在梗阻性肾病中,肾小管酸中毒可上调 ILK蛋白的表达与FN的沉积,加速肾小管间质纤维化。

Objective To observe integrin linked kinase(ILK)expression in obstructive nephropathy with renal tubular acidosis, and investigate the function of renal tubular acidosis on renal interstitial fibrosis.Methods 75 rate were divided into control group and unilateral ureteral obstruction(unilateral ureteral obstruction(UUO,n=25)group,and other 50 rats in UUO group.UUO group was divided into renal tubular acidosis (UUO1 group,n=31)group and non-renal tubular acidosis(UUO2,n=19)group,re-nal function and histology test was carried at the same time.7,14,21,28 days later after operation,the rats were killed in batches, then measured the expression of ILK in renal tissue by immunohistochemistry and western blot.Results Inflammatory cell infiltra-tion and interstitial fibrosis of UUO1 group were more serious under the light microscope than that of UUO2 group;there was only a small amount of ILK protein expression in control group,almost no FN protein deposition,expression of ILK and FN protein pre-cipitation of UUO2 group increased,and UUO1 group was more than UUO2 group.Conclusion In obstructive nephropathy,renal tubular acidosis can up-regulate expression of ILK and FN sedimentation,then lead to interstitial fibrosis promotion.
