瘦素、脂联素、抵抗素、内肥素与妊娠糖尿病胰岛素抵抗的相关性研究

目的:探讨脂肪因子瘦素、脂联素、抵抗素、内肥素与妊娠糖尿病(GDM)胰岛素抵抗的相关性.方法:实验分为正常育龄妇女组(44例)、正常妊娠妇女组(62例)和妊娠糖尿病患者组(63例),用ELISA方法分别检测3组瘦素(Leptin),脂联素(Adiponectin),抵抗素(Resistin),内肥素(Visfatin)的水平,用葡萄糖氧化酶法检测血糖水平,免疫发光法检测胰岛素水平,用HOMA-IR(稳态模型胰岛素抵抗指数)表示胰岛素抵抗状态,HOMA-IR=空腹血糖×空腹血胰岛素÷22.5,用SPSSll.5统计软件进行统计分析.结果:妊娠糖尿病患者组的瘦素水平明显高于正常妊娠妇女组[(13.50±7.14)ng/ml、(7.78±3.82)ng/ml,P<0.001],正常妊娠妇女组明显高于正常育龄妇女组[(7.78±3.82)ng/ml、(1.73±0.70)ng/ml,P<0.001]差异具有统计学意义;GDM 组的内肥素水平明显低于正常妊娠妇女组[(15.67±5.78)ng/ml、(22.43±5.68)ng/ml,P<0.001],正常妊娠妇女组明显低于正常育龄妇女组[(22.43±5.68)ng/ml、(36.46±13.34)ng/ml,P<0.001],差异具有统计学意义;GDM 组的脂联素水平低于正常妊娠妇女组[(5 491.71±2 986.00)ns/ml、(6 692.34±2 583.51)ng/ml,P=O.029],差异有统计学意义,正常妊娠妇女组明显低于正常育龄妇女组[(6 692.34±2 583.51)ng/ml、(11 076.82±3 694.75)ng/ml,P<0.1301],差异具有统计学意义;GDM组抵抗素水平与正常妊娠妇女组比较差异没有统计学意义.在妊娠糖尿病患者组,HOMA-IR与瘦素(r=0.352,P=0.005)正相关,与内肥素(,=-0.255,P=0.046)呈负相关.结论:妊娠糖尿病患者瘦素水平升高,内肥素和脂联素水平降低,瘦素和内肥素与胰岛素抵抗有关,瘦素和内肥素参与了妊娠糖尿病胰岛素抵抗的发生发展;脂联素和抵抗素与胰岛素抵抗不具有相关性,脂联素和抵抗素可能与妊娠糖尿病胰岛素抵抗的发生无关.

Relationship of leptin,adiponectin,resistin,visfatin and insulin resistance in gestational diabetes mellitus

Objective:To investigated the correlation between adipocytokines of leptin,adiponectin,resistin,visfatin and insulin resistance in gestational diabetes mellitus.Methods:Using 3-hour VPG-measured 75 g-OGTT for GDM diagnosis,63 pregnant women with GDM and 62 age-matched unaffected pregnant women were recruited,44 age-matched non-pregnant women without diabetes mellitus as the cortrol.Plasma leptin,adiponectin,resistin,visfatin levels were analyzed with enzyme-linked immunosorbent assay.Results:Plasma leptin l...
