目的：探讨新诊断2型糖尿病患者糖负荷后胰升糖素样肽-1（GLP-1）水平的变化。方法对30例新诊断2型糖尿病患者（糖尿病组）和10例健康志愿者（对照组）行口服葡萄糖耐量试验（OGTT）。分别于空腹，口服葡萄糖后30、60、120和180 min 各...目的：探讨新诊断2型糖尿病患者糖负荷后胰升糖素样肽-1（GLP-1）水平的变化。方法对30例新诊断2型糖尿病患者（糖尿病组）和10例健康志愿者（对照组）行口服葡萄糖耐量试验（OGTT）。分别于空腹，口服葡萄糖后30、60、120和180 min 各采集静脉血10 mL，测定血糖（葡萄糖氧化酶法）、血浆胰岛素（电化学发光免疫法）和GLP-1（7～36，酶联免疫吸附法）。观察 OGTT 中各时间点血糖、血浆胰岛素和 GLP-1（7～36）水平的变化。结果糖尿病组患者在 OGTT 过程中各时间点（空腹，餐后30、60、120和180 min）的血糖水平均高于对照组（均 P ＜0．05）。糖尿病组空腹及口服葡萄糖后120 min 胰岛素水平与对照组比较差异无统计学意义（P ＞0．05）；糖尿病组口服葡萄糖后胰岛素水平于60 min 达峰值，对照组胰岛素水平于30 min 达峰值，糖尿病组胰岛素峰值水平均低于对照组（P ＜0．05）；糖尿病组口服葡萄糖后180 min 胰岛素水平高于对照组、胰岛素曲线下面积则低于对照组（均P ＜0．05）。糖尿病组空腹和口服葡萄糖后各时间点的 GLP-1水平及曲线下面积与对照组比较差异无统计学意义（P ＞0．05）。结论新诊断2型糖尿病患者口服葡萄糖后 GLP-1（7～36）水平无异常。展开更多
