【摘要】：目的评价糖耐量正常(normal glucose tolerance,NGT)人群口服葡萄糖耐量试验(oral glucose tolerance test,OGTT)1 h血糖与胰岛素敏感性和胰岛β细胞功能的关系。方法收集101例NGT和76例糖耐量异常(impaired glucose tolerance,IGT)病人的临床资料;测定OGTT各时间点的血浆葡萄糖和胰岛素浓度;比较NGT 1 h血糖(1 hour postload plasma glucose,1-h PG)8.6 mmol/L组、NGT 1-h PG≥8.6 mmol/L组和IGT组的胰岛素敏感性和胰岛β细胞功能,分析OGTT 1-h PG与胰岛素敏感性和胰岛β细胞功能的关系。结果 NGT 1-h PG≥8.6 mmol/L组的空腹血糖、1-h PG、1-h胰岛素及胰岛素敏感指数(homeostasis model assessment of insulin resistance,HOMA-IR)均显著高于NGT 1-h PG8.6 mmol/L组;NGT 1-h PG≥8.6 mmol/L组的Matsuda指数、胰岛素分泌指数(ΔI3 0/ΔG3 0和ΔI6 0/ΔG6 0)均显著低于NGT 1-h PG8.6 mmol/L组(P均0.05)。但NGT 1-h PG≥8.6mmol/L组的空腹血糖、空腹胰岛素、1-h PG、1-h胰岛素、HOMA-IR、Matsuda指数、ΔI3 0/ΔG3 0和ΔI6 0/ΔG6 0与IGT组比较,差异无统计学意义(P均0.05)。多元线性回归分析显示1-h PG与ΔI30/ΔG30、Matsuda指数呈线性负相关。结论在NGT人群中,OGTT 1-h PG≥8.6 mmol/L人群胰岛素敏感性和胰岛β细胞功能低于1-h PG8.6 mmol/L组,1-h PG与胰岛素敏感性和胰岛β细胞功能相关。提示在NGT人群中,1-h PG浓度可作为评价胰岛素敏感性和胰岛β细胞功能的简易指标。
[Abstract]:Objective to evaluate the relationship between insulin sensitivity and islet 尾 cell function in oral glucose tolerance test (oral glucose tolerance test,OGTT) 1 h glucose test (oral glucose tolerance test,OGTT) in patients with normal glucose tolerance (normal glucose tolerance,NGT). Methods the clinical data of 101 patients with NGT and 76 patients with impaired glucose tolerance (impaired glucose tolerance,IGT) were collected and the plasma glucose and insulin concentrations at different time points of OGTT were measured. Insulin sensitivity and islet 尾 cell function were compared in NGT 1 h glucose (1 hour postload plasma glucose,1-h PG) 8.6 mmol/L group, NGT 1-h PG 鈮，
