摘要 目的研究转化生长因子β1(TGF-β1)+869T/C、+915G/C基因多态性与广东汉族糖尿病肾病(DN)的相关性。方法采用病例-对照方法进行研究,即以DN患者为病例组,糖尿病不伴肾病患者与健康对照者两组人群分别构成两个对照组进行比较研究。采用序列特异性引物聚合酶链反应(PCR—SSP)技术检测糖尿病肾病患者45例,糖尿病不伴肾病患者53例,健康对照组50例的TGF-β1第1号外显子+869T/C及+915G/C位点等位基因及基因型分布,并对该基因多态性与广东汉族糖尿病肾病的相关性进行分析。结果TGF-β1+869T/C、+915G/C基因多态性可区分为3种类型,分别为TT、TC、CC3种和GG、GC、CC3种;+869T/C中T、C等位基因的分布,DN组分别为0.414、0.586,糖尿病非肾病组分别为0.455、0.545,对照组分别为0.596、0.404;+915G/C中G、C等位基因的分布,DN组分别为0.714、0.286,糖尿病非肾病组分别为0.700、0.300,对照组分别为0.768、0.232;三组数据总体比较,+869T/C基因类型TT、TC、CC这一组数据总体上差异有显著性(P〈0.05),说明DN组、非肾病组和对照组这三组的TT、TC、CC3种基因类型总体分布存在差异,+915G/C基因类型差异无显著性(P〉0.05);三组数据两两比较,差异均无显著性(P〉0.05)。结论TGF—β1+869T/C及+915G/C位点基因多态性与广东汉族糖尿病肾病可能无关。
