[摘要] 目的 探讨非酒精性脂肪肝(NAFLD)与2型糖尿病(T2DM)患者胰岛素抵抗的关系。方法 98例确诊为2型糖尿病的患者根据是否合并非酒精性脂肪肝分为两组,比较两组患者的一般资料、实验室血清学指标。结果 98例2型糖尿病患者中,合并非酒精性脂肪肝组的体重指数(BMI)、空腹血糖(FPG)、空腹血清胰岛素(FInS)、胰岛素抵抗指数(HOMA-IR)、血清总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白(LDL-C)、血尿酸水平(UA)均显著增高;高密度脂蛋白(HDL-C)显著低于未合并非酒精性脂肪肝组。上述差异均有统计学意义(P<0.05)。结论 合并非酒精性脂肪肝的糖尿病患者存在更高的胰岛素分泌水平和更明显的胰岛素抵抗。

[Abstract] Objective To investigate the relationship between non-alcoholic fatty liver(NAFLD)and insulin resistance in type 2 diabetes(T2DM)patients. Methods All of 98 cases diagnosed as type 2 diabetes were divided into two groups:T2DM combined without NAFLD group and T2DM combined with NAFLD group. The general information and laboratory serum markers were measured. Results In 98 cases of type 2 diabetes,compared with T2DM combined without NAFLD,the levels of body mass index(BMI),fasting plasma glucose(FPG),fasting serum insulin(FInS),homeostatic model assessment of insulin resistance(HOMA-IR),serum total cholesterol(TC),triglycerides(TG),low density lipoprotein cholesterol(LDL-C)and uric acid (UA)were all significantly increased in T2DM combined with NAFLD(P<0.05);the level of high-density lipoprotein cholesterol (HDL-C) was obviously decreased in T2DM with NAFLD,compared with T2DM combined without NAFLD(P<0.05). Conclusion T2DM combined with NAFLD had higher level of insulin secretion and more significant insulin resistance than T2DM combined without NAFLD insulin resistance.

非酒精性脂肪肝(NAFLD)是指除外酒精和其他明确的损肝因素所致的,以弥漫性肝细胞大泡性脂肪变为主要特征的临床病理综合征,包括单纯性脂肪性肝病以及由其演变的脂肪性肝炎(NASH)和肝硬化。肝细胞内脂质特别是甘油三酯沉积是形成NAFLD的一个先决条件。导致脂质沉积的代谢异常机制目前尚未完全明确。本文通过对2型糖尿病合并NAFLD患者的BMI、血脂、血尿酸、空腹血糖、空腹血胰岛素水平、胰岛素抵抗指数的观察分析,旨在探讨NAFLD与胰岛素抵抗、脂代谢紊乱的关系。
1 资料与方法
1.1 一般资料
研究对象为我院2009年1~12月内分泌科及消化科住院的2型糖尿病患者,均符合WHO1999年的糖尿病诊断及分型标准,且未使用胰岛素治疗。根据是否合并NAFLD分为两组,合并NAFLD组(A组)56例,未合并NAFLD组(B组)42例。NAFLD诊断根据2006年中华医学会肝脏病分会《非酒精性脂肪性肝病诊疗指南》的临床诊断标准[1]。
1.2 方法
回顾性分析研究对象的病史,包括性别、年龄、糖尿病病程等 ......
