非酒精性脂肪肝血清脂联素与肥胖和胰岛素抵抗关系的研究

目的研究非酒精性脂肪肝（NAFLD）患者血清脂联素与肥胖和胰岛素抵抗的关系。方法测定该院体检和住院人群中45例NAFLD患者和31例年龄、性别相匹配的正常对照者空腹血清脂联素，同时检测其身高、体重、腰围、臀围、血压、血脂、肝功能及胰岛素水平，并计算体重指数、腰臀比和采用稳态模型法计算IRI。结果血清脂联素浓度NAFLD组（7．07±1．10）ng／mL比正常对照组（10．68±1．45）ng／mL明显降低，P〈0．05。相关分析显示血清脂联素与HOMA—IR、ALT、GGT、腰臀比、体重指数、三酰甘油（GT）呈负相关，与高密度脂蛋白胆固醇呈正相关；而与性别、年龄、收缩压、舒张压、天冬氨酸转氨酶、总胆固醇、低密度脂蛋白胆固醇、血糖无相关性。结论NAFLD患者血清脂联素水平降低且伴有明显的IR,IR是NAFLD患者基本特征之一，中心型肥胖、低脂联素水平是NAFLD的危险因素；NAFLD患者脂联素水平降低和中心型肥胖可能共同参与了IR的发生、发展，进而影响NAFLD的发病。

Relationship between serum adiponectin,obesity and insulin resistance in nonalcoholic fatty liver disease

Objective] To assess the relationship between serum adiponectin, obesity and insulin resistance in nonalcoholic fatty liver disease (NAFLD). Methods] Fasting serum adiponectin in 45 NAFLD patients and 31 matched normal control subjects was measured by ELISA. Insulin resistance by homeostasis model (HOMA), height, weight, waist circumstance, hip girth, waist to hip ratio (WHR), body mass index (BMI), blood pressure, blood glucose, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, alanine a...
