　　【摘要】 目的 观察肥胖T2DM患者血清铁蛋白(SF)、同型半胱氨酸(Hcy)水平的变化及其相关因素。 方法 选取新诊断T2DM患者62例和体检者38例，根据BMI分为T2DM合并肥胖(T2DM+Ob)组26例、单纯T2DM组36例、单纯肥胖(Ob)组18例及正常对照(NC)组20名，比较各组血清SF、Hcy、FPG、FIns、TC、TG、FFA及胰岛素抵抗指数(HOMA-IR)水平,并分析其相关性。 结果 SF和Hcy水平在NC组、Ob组、T2DM+Ob组和Ob组逐渐升高[SF：(168.70±20.00) vs (202.11±23.48) vs (236.08±32.38) vs (286.19±34.92) ng/ml;Hcy：(6.99±1.37) vs (8.61±1.98) vs (9.97±1.30) vs (13.64±1.92) μmol/L， P<0.05]。多元逐步回归分析显示，T2DM患者SF与BMI、FFA呈正相关(P<0.05)。 结论 T2DM患者SF和Hcy水平高于非糖尿病人群，其中，肥胖者SF和Hcy高于非肥胖者，提示SF和Hcy可能参与肥胖、糖尿病相关。

　　【Abstract】 Objective To investigate the changes of serum ferritin(SF) and homocysteine (Hcy) and their associated factors in obese type 2 diabetes mellitus. Methods A total of 62 newly diagnosed type 2 diabetes and 38 controls were enrolled in this study. All the participants were divided into four groups :obeseT2DM group (DO, n=26), T2DM without obesity group (NDO, n=36), obese group (Ob, n=18) and control group(NC, n=20).Serum SF, Hcy, FPG,TC, TG,FFA, homeostatic model assessment for insulin resistance (HOMA-IR) and their association were tested in all the groups. Results Serum levels of SF and Hcy were gradually increased in NC group, OB group, NDO group and DO group[SF：(168.70±20.00)vs(202.11±23.48)vs(236.08±32.38)vs(286.19±34.92)ng/ml;Hcy：(6.99±1.37)vs(8.61±1.98)vs(9.97±1.30)vs(13.64±1.92)μmol/L，P<0.05]. SF was positively correlated with BMI, FFA in T2DM patients by the muti-stepwise regression analysis(P﹤0.05). Conclusions Serum levels of SF and Hcy were increased in T2DM patients. Serum SF and Hcy may be involved in the process of obesity and T2DM.
