摘要: 目的  研究非酒精性脂肪肝(NAFLD)患者血清游离脂肪酸(FFA)水平及其与胰岛素抵抗(IR)的关系。方法  测定118例NAFLD患者(NAFLD组)及103名健康体检者 (正常对照组)的血清FFA并计算胰岛素抵抗指数(HOMA-IR)。结果  NAFLD组血清FFA浓度为(752.50±101.42)μmol/L, HOMA-IR为1.48±0.42,均高于正常对照组[(441.75±95.64) μmol/L, 0.67±0.33](P<0.01)。NAFLD组FFA与HOMAIR呈正相关 (r=0.325,P<0.05)。结论  FFA与NAFLD密切相关,FFA致NAFLD可能通过IR起作用。

Abstract: Objective To investigate the relationship between serum free fatty acid (FFA) and insulin resistance (IR) in patients with nonalcoholic fatty liver disease (NAFLD).  Methods A total of 118 patients with NAFLD and 103 healthy subjects were enrolled as NAFLD group and control group. Their serum FFA were measured,and homeostasis model assessmentinsulin resistance (HOMAIR) indices were calculated.  Results The level of serum FFA was (752.50±101.42) μmol/L, and HOMA-IR was 1.48±0.42 in NAFLD group. The levels of serum FFA and HOMAIR were higher than those in control group [(441.75±95.64) μmol/L,0.67±0.33] (P<0.01).Serum FFA level was positively correlated with HOMAIR in NAFLD group (r=0.325,P<0.05). Conclusions FFA is closely associated with NAFLD, and IR may play a role in the pathogenesis of FFA to NAFLD.
