1、2型糖尿病患者血清Ghrelin水平與肥胖、胰島素抵抗的相關研宄郭大敏吳和波勞程強曾灶英(廣東省佛山市南海區(qū)第八人民醫(yī)院528216)【摘要】目的探討糖尿病患者血清Ghrelin水平與肥胖、胰島素抵抗之間的關系。方法將300例2型糖鉍病患者根據(jù)BMI分為體重過低、體重正常、超重和肥胖4組;采用EUSA法測定血清屮Ghrelin水平變化;用直線相關及多元逐步回歸分析血清Ghrelin與上述指標的相關性。結果糖尿病肥胖組的Ghrelin水平顯著低于糖鉍病體重過低組、體重正常組和超重組(p<0.05),而且隨著BMI增加而減少;糖尿病患者血清Gh
2、relin與BMI、HOMA-IR、FINS和WHR呈顯著負相關(r=-0.728,p<0.01;r=-0.562,p<0.01;r=-0.490,p<0.01;r=-0.389,p<0.01);BMI是影響血淸Ghrelin水平的最重要變量。結論BMI是糖姒病患者血清Ghrelin水平的主要相關因素;Ghrelin參與丫體脂形成和胰島素抵抗的變化,在糖尿病的發(fā)病過程屮起著重要作用?!娟P鍵詞】糖鉍病Ghrelin肥胖胰島素抵抗【中圖分類號】R587.2【文獻標識碼】A【文章編號】2095-1752(2013)26-0030
