单纯肥胖及糖尿病患者血清脂联素水平研究

目的 探讨脂联素与体脂含量、血糖、血脂和胰岛素抵抗的相关性。方法 放射免疫法测定19例正常对照者，23例单纯肥胖者，31例2型糖尿病非肥胖者，26例2型糖尿病合并肥胖患者血浆中脂联素水平。结果 正常对照组和单纯肥胖组的血清脂联素水平没有显著性差异，而2型糖尿病组和2型糖尿病肥胖组的血清脂联素水平显著低于前两组，但可以看到在2型糖尿病的前提下，非肥胖组与肥胖组的血清脂联素水平的差异没有显著性。以性别分组进行独立两样本t检验，血清脂联素水平存在显著差异。血清脂联素与体重指数、腰围、腰臀比、体脂含量、空腹血糖、胰岛素敏感指数、血清甘油三酯、高密度脂蛋白显著相关。多元逐步回归分析发现血清高密度脂蛋白、空腹血糖、腰围、体脂含量进入回归方程。结论 血清脂联素水平存在性别差异，其与肥胖、2型糖尿病和胰岛素抵抗相关。

A Study on the Serum Adiponectin Concentration in Patients with Obesity,Diabetes Mellitus

Ojective To investigate the relationship between the serum adiponectin concentration and insulin resistance in patients with obesity and diabetic patients. Methods Fasting serum adiponectin concentration was measured by RIA in 19 normal subjects, 23 obese subjects, 31 diabetic patients without obesity and 26 diabetic patients with obesity. Results There was no significant difference in serum adiponectin concentration between nomal and obese subjects, and between type 2 diabetics without obesity and type 2 diabetics with obesity . The serum adiponectin concentrations was significantly higher in type 2 diabetics without or with obesity than that in nomal and obese subjects. There was significant difference in serum adiponectin concentration between female and male subjects. Body mass index (BMI), waist circumference(WC), waist-hip ratio (WHR), body fat percentage (BF%), fasting plasma glucose (FPG), insulin sensitivity index (ISI), triglyceride (TG) and high density lipoprotein-C (HDL-C) were significantly correlated with serum adiponectin concentration. A stepwise mulitiple linear regression analysis showed that HDL-C, FPG, WC, BF% entered the regression equation. Conclusion Serum adiponection level was associated with sex, obesity, type 2 diabetes mellitus and insulin resistance.
