目的  探討胰升血糖素樣肽-1（GLP-1）對肝切除術(shù)后應(yīng)激性糖代謝紊亂的影響。
方法  將大鼠隨機分3組。Ⅰ組又分Ⅰg組，注射50%葡萄糖（0.5 g/kg體重）+生理鹽水； Ⅰglp組，注射50%葡萄糖+GLP-1（0.3 nmol/kg體重）行葡萄糖耐量實驗。Ⅱ組切肝約65%后分Ⅱg和Ⅱglp組，分別于術(shù)后第1、3、5天 按Ⅰ組方法分別行葡萄糖耐量實驗。Ⅲ組切肝后第1天行葡萄糖耐量實驗，GLP-1按0.45 nmol/kg體重給予。觀察峰值血糖、30分鐘血糖及曲線下面積（AUC0~30）。
結(jié)果  Ⅰglp組峰值血糖和30分鐘血糖及AUC0~30明顯低于Ⅰg組； Ⅱg組術(shù)后 1、3、5天峰值血糖和30分鐘血糖及AUC0~30均明顯高于Ⅰg組。Ⅱglp組術(shù)后第1天峰值血糖與Ⅱg組差異無顯著意義； 但Ⅲ組明顯低于Ⅱg組及Ⅱglp組，30分鐘血糖也明顯低于Ⅱg組，且AUC0~30也明顯低于Ⅱg組及Ⅱglp組； Ⅱglp組術(shù)后 3、5天峰值血糖、術(shù)后1天血糖值、30分鐘血糖及AUC0~30均明顯低于Ⅱg組，與Ⅰg組相似。
結(jié)論  肝切除術(shù)后機體對葡萄糖的耐量下降，輸注外源性GLP-1可促進機體對葡萄糖的利用； 術(shù)后早期GLP-1促進機體利用葡萄糖的作用明顯減弱，但增加GLP-1的劑量仍可改善機體對葡萄糖的利用； 隨著手術(shù)應(yīng)激程度減輕，GLP-1促進機體利用葡萄糖能力增強，可達正常水平。
