    摘要:

    目的:探讨先天性肾积水患儿肾脏水通道蛋白AQP1-4 的表达与肾实质厚度和肾小球滤过率(GFR)变化之间的关系。方法:利用Western blot检测AQP1-4蛋白在10例先天性肾积水患儿(年龄62.3±18.3个月)10个肾组织和6例来自肾母细胞瘤手术切除患儿的正常肾脏组织(年龄62.7±17.1个月)中的相对表达量。同时对患侧肾脏肾实质厚度和GFR进行评估。积水肾脏AQP1-4表达与GFR以及肾实质厚度之间进行Pearson相关分析检验。结果:肾积水组AQP1-4蛋白相对表达均明显低于正常组(P<0.05)。B超测量术前积水侧肾脏肾实质厚度平均为4.59±2.25 mm。99mTc-DTPA 测定积水侧肾脏GFR较对侧肾脏明显下降(40±12 mL/min vs 105±20 mL/min, P<0.05)。积水组肾脏中AQP1-4蛋白相对表达量与肾实质厚度之间呈正相关,与患侧肾脏GFR之间亦呈正相关。积水侧肾脏肾实质厚度与GFR之间呈正相关。结论:先天性积水患儿肾脏AQP1-4蛋白表达下降,其表达量与肾实质厚度和肾脏GFR的变化呈正相关。

    Abstract:

    OBJECTIVE: To study the relationship of renal aquaporin -1, -2, -3, and -4 (AQP1-4) expression with renal parenchymal thickness and glomerular filtration rate (GFR) in children with congenital hydronephrotis. METHODS: Renal tissue samples were obtained from 10 kidneys of 10 children (age: 62.3±18.3 months) with hydronephrosis and who underwent Anderson-Hynes pyeloplasty. Renal control samples were obtained from 6 children (age: 62.7±17.1 months) undergoing nephrectomy for nephroblastoma and were confirmed histologically as normal renal tissues. Renal parenchymal thickness of the hydronephrotic kidneys was measured by ultrasound preoperatively and was verified at operation. Renal GFR was assessed using 99mTc-DTPA scintigraphy preoperatively. Western blot was used to examine the expression of AQP1-4 in the renal tissues. The correlations of renal AQP1-4 expression with the renal parenchymal thickness and GFR were assessed by Pearson correlation analysis. RESULTS: The expression of AQP1-4 in the hydronephrotis group was markedly reduced compared to that in the control group (P<0.05). The mean renal parenchymal thickness of the hydronephrotic kidney was 4.59±2.25 mm measured by ultrasound preoperatively. The mean GFR of the obstructed kidney was significantly lower than that of the contralateral kidney in the hydronephrosis group (40±12 mL/min vs 105±20 mL/min; P<0.05). The expression of AQP1, 2, 3 and 4 was positively correlated with preoperative renal GFR and renal parenchymal thickness in the hydronephrosis group (P<0.05). Renal parenchymal thickness was positively correlated with renal GFR (P<0.05). CONCLUSIONS: The expression of renal AQP1-4 is reduced in children with congenital hydronephrosis. The expression levels of AQP1-4 are positively correlated with renal parenchymal thickness and GFR.
