摘要： 目的〖HTSS〗〖KG*2〗探讨不同糖耐量人群血循环中脂肪细胞型脂肪酸结合蛋白（adipocyte fatty acidbinding protein,AFABP）的水平及其与肥胖程度、血压、血糖、血脂、胰岛素抵抗程度及胰岛素分泌功能之间的相关性。
〖HTH〗方法〖HTSS〗〖KG*2〗选取于河北医科大学第三医院就诊、并行口服葡萄糖耐量试验者120例，按照WHO制定的糖尿病诊断与分型标准将受试对象分为3组：2型糖尿病组（type 2 diabetes mellitus，T2DM,n=62）、葡萄糖调节受损组（impaired glucose regulation，IGR,n=32）、正常对照组（normal glucose tolerance，NGT,n=26）。根据《中国成人超重和肥胖症预防控制指南》确立的肥胖标准将T2DM组分为非肥胖组（A组,n=30，BMI<28，男性16例，女性14例）和肥胖组（B组,n=32，BMI≥28，男性22例，女性10例）。测定身高、体质量、腰围、臀围、收缩压、舒张压，计算体质量指数（body mass index，BMI）、腰臀比，测定胆固醇（total cholesterol,TC)、三酰甘油（concentrations of triglyceride,TG)、低密度脂蛋白胆固醇（lowdensity lipoprotein cholesterol,LDLC）、高密度脂蛋白胆固醇(highdensity lipoprotein cholesterol,HDLC)、血糖、HbA1c、胰岛素水平，并计算胰岛素曲线下面积（AUCINS）、血糖曲线下面积（AUCGLU）、胰岛素抵抗指数(HOMAIR)、胰岛β细胞功能指数（HOMAβ）。
〖HTH〗结果〖HTSS〗〖KG*2〗T2DM组血清AFABP水平最高，明显高于IGR及NGT组（P＜005）；IGR组血清AFABP水平明显高于NGT组（P＜005）；T2DM B组BMI、WC、HC、UA、FINS、HOMAIR、HOMAβ均高于T2DM A组（P＜005）；2型糖尿病肥胖组血清AFABP水平明显高于非肥胖组（P＜005）；血清AFABP水平与BMI、WC、HC、UA、TC、TG、FPG、2 hPG、AUCGLU、HOMAIR呈显著正相关(P＜005)，与LDLC、HDLC、SBP、DBP、FINS、AUCINS、HOMAβ无相关(P＞005)。多元逐步回归分析显示，BMI、HbA1c和UA为血清AFABP水平的独立影响因素。
〖HTH〗结论〖HTSS〗〖KG*2〗血清AFABP与肥胖、胰岛素抵抗和糖脂代谢密切相关，是代谢综合征的异常标志。

Abstract: Abstract］ Objective〖HTSS〗〓To investigate the level of serum adipocyte fatty acidbinding protein(AFABP) and the relationship between serum AFABP and body mass index(BMI), blood pressure, blood glucose, blood lipid, HOMAinsulin resistance index(HOMAIR), insulin levels in Han Chinese population with different glucose tolerance.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓A total of 120 subjects were enrolled in this study. They were divided into 3 groups according to 75 g oral glucosetolerancetest(OGTT), including normal glucose tolerance(NGT, n=26), impaired glucose regulation(IGR, n=32), and type 2 diabetes mellitus(T2DM, n=62). The T2DM group was divided into 2 subgroups by BMI according to the guidelines of the prevention and treatment adiposity in China, which included group A(nonobese subjects) and group B(obese subjects). Clinical and biochemical metabolic parameters were measured.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The levels of serum AFABP were significantly higher in T2DM subjects than those of IGR and NGT subjects(P＜001). Compared with NGT group, fasting serum AFABP levels were significantly increased in IGR group(P＜001). Compared with T2DM group, BMI、WC、HC、UA、FINS、HOMAIR、HOMAβlevels were significantly increased in IGR group(P＜005). The level of serum AFABP was significantly higher in T2DM obese subjects than T2DM nonobese subjects(P＜001). Serum AFABP was correlated positively with BMI、WC、HC、UA、TC、TG、FPG、2 hPG、AUCGLU and HOMAIR(all P＜005). There was no correlation between serum AFABP and LDLC、HDLC、SBP、DBP、FINS、AUCINS、HOMAβ(all P＞005). Multiple regression analysis showed that BMI, HbA1c and UA were independently related factors for serum AFABP levels.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The level of AFABP is associated with obesity, insulin resistance, abnormal glucose and lipid metabolism. Measurement of serum AFABP concentrations might be useful for diagnosis and prevention of T2DM.
