不同糖耐量人群血清betatrophin水平与胰岛β细胞分泌功能及胰岛素抵抗的相关性

目的检测不同糖耐量人群的血清促代谢因子betatrophin水平,探讨betatrophin与胰岛β细胞分泌功能及胰岛素抵抗的关系。方法选取2014年9月至2015年1月在重庆医科大学附属第一医院门诊就诊者110人为研究对象,其中新诊断2型糖尿病患者47例(T2DM组)、糖调节受损者27例(IGR组)和正常糖耐量者36名(NGT组),行静脉葡萄糖耐量试验(IVGTT),测0~10min胰岛素水平,计算急性胰岛素反应(AIR3-5)及0~10min胰岛素分泌曲线下面积(AUC)、稳态模型胰岛素抵抗指数(HOMA-IR)及稳态模型胰岛β细胞功能指数(HOMA-β),并采用酶联免疫吸附实验(ELIS...

Summary:目的检测不同糖耐量人群的血清促代谢因子betatrophin水平,探讨betatrophin与胰岛β细胞分泌功能及胰岛素抵抗的关系。方法选取2014年9月至2015年1月在重庆医科大学附属第一医院门诊就诊者110人为研究对象,其中新诊断2型糖尿病患者47例(T2DM组)、糖调节受损者27例(IGR组)和正常糖耐量者36名(NGT组),行静脉葡萄糖耐量试验(IVGTT),测0~10min胰岛素水平,计算急性胰岛素反应(AIR3-5)及0~10min胰岛素分泌曲线下面积(AUC)、稳态模型胰岛素抵抗指数(HOMA-IR)及稳态模型胰岛β细胞功能指数(HOMA-β),并采用酶联免疫吸附实验(ELISA)法测定空腹血清betatrophin水平,分析betatrophin与以上指标及代谢相关指标的关系。多组间比较采用单因素方差分析,相关性分析采用Pearson相关分析。结果血清betatrophin水平在T2DM组和IGR组显著高于NGT组[分别为2.08(1.08~2.89)、1.52(0.54~2.55)、0.76(0.44~0.97)μg/L,F=16.142,P〈0.01]。双变量相关分析提示,血清betatrophin水平与体重、体质指数、腰围、腰臀比、空腹血糖、餐后2h血糖、糖化血红蛋白、空腹胰岛素、120min胰岛素、HOMA-IR和甘油三酯(TG)呈正相关(r=0.288—0.562,均P〈0.05),与高密度脂蛋白胆固醇呈负相关(r=0.338,P〈0.01)。多元逐步回归分析提示,HOMA-IR和TG是血清betatrophin水平的独立影响因素(βHOMA-IR=0.438,βTG=0.300,均P〈0.01)。结论在T2DM及IGR个体中血清betatrophin水平显著增高,且与糖脂代谢及胰岛素抵抗密切相关,但与胰岛β细胞第一时相分泌功能无直接相关性。
Bibliography:Objective To detect the levels of serum betatrophin in people with different glucose tolerance and to investigate the relationship between serum betatrophin levels and insulin secretion of pancreatic β cells as well as insulin resistance. Methods Forty seven patients with newly diagnosed type 2 diabetes mellitus (T2DM group), 27 patients with impaired glucose regulation (IGR group) and 36 individuals with normal glucose tolerance (NGT group) were recruited in the study from September 2014 to January 2015. All subjects underwent intravenous glucose tolerance test (IVGTT). Insulin levels during the first 10 min were measured and acute insulin response (AIR3-5), 0-10 minutes insulin area under the curve (AUC) were evaluated. Homeostasis model assessments for insulin resistance (HOMA-IR) and for β-cell function (HOMA-β) were calculated. Meanwhile fasting serum betatrophin was determined by enzyme-linked immunosorbent assay(ELISA). The relationships between serum betatrophin, indexes mentioned above and metabolic
