摘要 目的探讨妊娠期糖尿病(GDM)患者网膜脂肪组织与腹直肌葡萄糖转运蛋白4(GLUT4)表达的差异及其与胰岛素抵抗(IR)的关系。方法逆转录-聚合酶链反应(RT-PCR)检测23例GDM(GDM组)、21例正常孕妇(NGT组)网膜脂肪组织与腹直肌GLUT4mRNA的表达水平,测量空腹血糖(FPG)、空腹胰岛素(FINS)等指标,并计算胰岛素抵抗指数(HOMA-IR)值。结果2组腹直肌GLUT4mRNA表达量均高于对应组的网膜脂肪(P<0.05);GDM组网膜脂肪GLUT4mRNA表达量低于NGT组(P<0.05);2组腹直肌GLUT4mRNA表达量比较差别无统计学意义(P>0.05)。网膜脂肪GLUT4mRNA表达量与孕前BMI、孕前腰臀比、FPG、FINS、HOMA-IR呈负相关(P<0.05);腹直肌GLUT4mRNA表达量与孕前BMI、孕前腰臀比、FPG、FINS、HOMA-IR均无相关性(P>0.05)。结论在GDM患者网膜脂肪中GLUT4mRNA存在低表达,并且这种低表达可能与IR有关。
