简介：目的:通过测定糖尿病性白内障患者血清中糖代谢指标、胰岛素抵抗与房水和血清中炎症因子的水平,探讨其相关性。方法:随机选取我院2017-02/2018-01糖尿病性白内障患者69例(观察组)和白内障患者65例(对照组),检测两组患者血清中糖化血红蛋白(HbA1c)、空腹血糖(FPG)、空腹胰岛素(FINS)的水平,计算胰岛素抵抗指数(HOMA-IR);同时检测房水和血清中的胰岛素样生长因子-1(IGF-1)、白细胞介素-6(IL-6)含量,对HbA1c、HOMA-IR与房水和血清中IGF-1、IL-6含量进行相关性分析。结果:对照组血清中的FPG、HbA1c、HOMA-IR,以及房水和血清中IGF-1、IL-6含量显著低于观察组,差异有统计学意义(均P<0.05)。HbA1c与房水及血清中的IGF-1和IL-6均呈正相关(P<0.05)。HOMA-IR与房水及血清中的IGF-1和IL-6均呈正相关(P<0.05)。结论:糖尿病性白内障患者HbA1c、HOMA-IR与房水及血清中的IGF-1、IL-6含量具有相关性,通过对上述指标的测定可以辅助判断病情。
