摘要 目的 探讨肥胖及2型糖尿病患者血浆颗粒蛋白前体(PGRN)与慢性炎性反应及胰岛素抵抗的关系.方法 156例患者按口服葡萄糖耐量试验结果分为正常糖耐量组(NGT组,82例)、2型糖尿病组(T2DM组,74例).再以体质量指数(BMI) 25 kg/m^2为切点,将两组分为四个亚组:正常糖耐量正常体质量亚组(NGT-NW组,BMI< 25 kg/m^2,43例),正常糖耐量肥胖亚组(NGT-OB组,BMI≥25 kg/m^2,39例),2型糖尿病正常体质量亚组(T2DM-NW组,BMI< 25 kg/m^2,34例),2型糖尿病肥胖亚组(T2DM-OB组,BMI≥25 kg/m^2,40例).检测各组空腹血糖(FPG)、餐后2h血糖(2 h PG)、糖化血红蛋白(HbA1c)、三酰甘油(TG)、空腹胰岛素(FINS)、血浆PGRN等,计算BMI、稳态模型评估法胰岛素抵抗指数(HOMA-IR)及稳态模型评估法胰岛β细胞功能(HOMA-β).结果 T2DM组PGRN明显高于NGT组[(212.5±45.8) μg/L比(166.4±61.6) μg/L],T2DM-OB组和NGT-OB组PGRN明显高于相应的T2DM-NW组和NGT-NW组[(226.2 ±35.3) μg/L比(196.5±51.4) μg/L和(184.7±62.6) μg/L比(149.6± 56.2)μg/L],差异有统计学意义(P<0.05).PGRN与体质量、腰围、FINS、HOMA-IR、BMI、收缩压、FPG、2 hPG、HbA1c、TG、白细胞介素-6(IL-6)呈显著正相关(P< 0.05或< 0.01),与HOMA-β呈显著负相关(P<0.05).多元线性回归分析结果显示,BMI、HbA1c、IL-6 、TG与PGRN独立相关(P<0.05).结论 肥胖及2型糖尿病患者血浆PGRN均升高,其升高程度与糖脂代谢紊乱、炎性反应及胰岛素抵抗的程度密切相关.
