摘要: 目的 探讨2型糖尿病(T2DM)患者空腹与餐后2 h游离脂肪酸(FFA)浓度和胰岛素抵抗的关系。方法 测定100例T2DM患者(根据亚洲糖尿病论坛的推荐分为控制良好和控制不良2组)及50名正常对照者的糖化血红蛋白(HbA1c)、空腹胰岛素(FINS)、空腹血糖(FPG)、餐后2 h血糖(2 h PG)、空腹FFA及餐后2 h FFA。以稳态模式评估胰岛素抵抗指数(HOMA-IR)。结果 与对照组比较,T2DM组的FPG 、2 h PG、FFA、2 h FFA、HbA1c、HOMA-IR均明显增高(P<0.01)。T2DM控制不良组各项指标均高于控制良好组(P<0.05),FFA、2 h FFA与HOMA-IR、HbA1c、FPG、2 h PG均呈明显的正相关(r分别为0.910、0.876,0.851、0.759,0.908、0.746,0.769、0.674,P<0.01)。结论 T2DM患者体内FFA浓度的增高与胰岛素抵抗存在明显相关性,与T2DM的发病机制有密切关系。

Abstract: Objective To investigate the relationship between the fasting levels and levels after diet for 2h of free fatty acid (FFA) and insulin resistance in patients with type 2 diabetes mellitus (T2DM).  Methods  A total of 100 T2DM patients were enrolled and classified into good-control group and no-good-control group according to Asian Diabetes Forum, and 50 healthy controls were also enrolled. Their glycosylated hemoglobin (HbA1c),fast insulin (FINS), fast plasma glucose (FPG), 2 h plasma glucose (2 h PG), fast FFA and 2 h FFA were determined. Homeostasis model assessment-insulin resistance index (HOMA-IR) was evaluated by HOMA.  Results Compared with those in control group, FPG, 2 h PG, FFA, 2 h FFA, HbA1c and HOMA-IR increased significantly in T2DM group (P<0.01). The parameters in no-good-control group were higher than those in good-control group (P<0.05). FFA and 2 h FFA were positively correlated with HOMA-IR, HbA1c, FPG and 2 h PG(r=0.910 and 0.876, 0.851 and 0.759, 0.908 and 0.746 and 0.769 and 0.674,P<0.01).  Conclusions The increasing of FFA levels is positively related with insulin resistance in T2DM patients, and may play an important role in the development of T2DM.
