[摘要]目的 探讨2型糖尿病(T2DM)患者血管内皮生长因子(VEGF)、白细胞介素-6(IL-6)和肿瘤坏死因子(TNF-α)水平的变化及其临床意义。 方法 应用放射免疫法对40例2型糖尿病肾病患者、36例2型糖尿病非肾病患者及38例健康人(健康对照组)进行血清VEGF、IL-6及TNF-α水平的检测。 结果 2型糖尿病肾病组血清VEGF、IL-6及TNF-α水平显著高于健康对照组(P<0.01)及2型糖尿病非肾病组(P<0.01)。 结论 VEGF、IL-6及TNF-α是2型糖尿病肾病发生的重要炎症反应介质,提示高水平的VEGF、 IL-6及TNF-α可能在T2DM及其肾病并发症的发生、发展过程中起到一定作用,检测其水平变化可作为2型糖尿病肾病临床诊断的参考依据。

[Abstract]Objective To study the detection of the level and its clinical significance of vascular endothelial growth factor(VEGF). interleukin-6(IL-6) and tumor necrosis factor-a(TNF-α) in patients with type 2 diabetic nephropathy(DN). Methods The levels of VEGF, IL-6and TNF-α in 40 patients with DN, 36 patients diagnosed simply type 2 diabetes mellitus(DM) and 38 healthy persons (healthy controls) were radioimmunologically examined. Results The level of VEGF, IL-6 and TNF-α in the DN group were markedly lower than those in the healthy group(P<0.01) and the simply type 2 DM group(P<0.01). Conclusion The VEGF, IL-6 and TNF-α were important inflammatory mediators in the development of the DN, high levels of VEGF, IL-6 and TNF-α may play important roles in the occurrence and development of the type 2 diabetes mellitus and diabetic complications, detecting the level changes can be used as references for clinical diagnosis of type 2 diabetic nephropathy.

糖尿病肾病(diabetes nephropathy, DN)是糖尿病微血管病变的主要并发症之一[1]。目前多认为DN属于一种以蛋白尿为临床特点的肾小球疾病,但其发病机制尚未完全明确[2]。目前关于糖尿病及其并发症发生、发展的炎症学说受到广泛关注[3-4]。免疫功能的变化是其主要机制之一,VEGF是一种促血管生长因子,可促进血管内皮生长因子分化、增生及腔管形成,增强血管通透性,维持血管稳定[5]。IL-6是由机体单核-巨噬细胞等多种免疫参与细胞所产生的重要的生物活性细胞因子,TNF-α可以激活中性粒细胞和单核巨噬细胞,刺激其合成IL-1、IL-6、IL-8等炎性细胞因子,促进炎症反应的发生。本研究通过对三组患者检测其体内VEGF、IL-6及TNF-α水平变化,探讨其在2型糖尿病发生、发展中的作用。
