非酒精性脂肪肝血清脂联素与胰岛素抵抗及铁代谢的相关性

目的:研究非酒精性脂肪肝患者血清脂联素水平与胰岛素抵抗程度及血清铁代谢的相关性。方法:选择非酒精性脂肪肝患者35例和健康体检者56例为研究对象,测定体重指数(BMI),检测空腹血糖(FBG)、丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)、糖化血红蛋白(HbA1C)、尿酸(UA)、尿微量白蛋白/尿肌酐(UAlb/Ucr)值等生化指标,并行肝脏B超检查。放射免疫法测定空腹胰岛素(FINS),计算胰岛素抵抗指数(HOMA IR);同时测定血清铁(SI)、铁蛋白(SF)、转铁蛋白(TRF)、血清脂联素水平。结果:(1)非酒精性脂肪肝组BMI、TC、TG、FBG、HOMAIR、UAlb/Ucr、SF均高于对照组,血清脂联素水平低于对照组。(2)相关性研究表明,血清脂联素与SF、FINS、HDL呈正相关,与FBG、HbA1C、HOMA IR、TC、LDL呈负相关。结论:非酒精性脂肪肝患者血清脂联素下降,血清脂联素水平与胰岛素抵抗指数呈负相关,与铁蛋白呈正相关。

Relationships among adiponectin,ferritin metabolism and insulin resistance in patients with nonalcoholic fatty liver disease

Objective:To investigate the relationships among adiponectin,ferritin metabolism and insulin resistance in patients with nonalcohlic fatty liver disease(NAFLD).Methods:Thirty-five patients with NAFLD and 56 healthy controls were studied.Abdominal ultrasound was taken for fatty liver examination.Serum ferritin,insulin levels and adiponectin were determined by radioimmunoassay(RIA).Insulin resistance indexe was assessed by the homeostasis assessment-insulin resistance(HOMA-IR).Other biochemical variables were...
