摘要 目的探讨胆囊三角脂肪堆积与其脂肪组织中脂肪酶活性及胰岛素抵抗(IR)的关系。方法选择择期行腹腔镜胆囊切除术患者55例,根据术中观察胆囊三角脂肪堆积程度分为脂肪堆积组28例、正常组27例。计算两组腰臀比(WHR);检测其空腹胰岛素(FINS)、游离脂肪酸(FFA)、胰岛素抵抗指数(HOMA-IR),以及脂肪组织中的甘油三酯脂酶(ATGL)、激素敏感性脂肪酶(HSL)mRNA表达与ATGL、HSL蛋白表达;分析各检测指标的相关性。结果与正常组比较,脂肪堆积组的WHR、FINS、FFA均升高,ATGL mRNA、HSL mRNA及其蛋白表达均下降(P<0.05或<0.01)。ATGL、HSL蛋白表达均与FINS和FFA呈负相关(P均<0.05)。脂肪组织中的ATGL与HSL蛋白表达呈高度正相关(r=0.708,P<0.01)。结论胆囊三角脂肪堆积与其脂肪组织中的ATGL、HSL蛋白表达及IR有关,WHR可作为临床预测胆囊三角脂肪堆积程度的指标。
