目的:探讨骨保护素(osteoprotegerin, OPG)基因rs2073618、rs3102735位点多态性及突变与绝经后2型糖尿病(Type 2 diabetes mellitus, T2DM)女性骨代谢的关系,为后续治疗提供依据。方法:1) 选取石河子地区研究对象200例,所有研究对象均为绝经后女性,根据骨密度(Bone mineral density, BMD)分为:正常对照组(A组)、单纯骨量异常组(B组),根据不同的糖耐量水平分为:单纯T2DM (C组)、T2DM伴骨量异常组(D组)。2) 测定骨、糖、脂、糖化血红蛋白(Glycated hemoglobin, HbA1c)、BMD (L1-4) 及BMD (股骨颈)等相关指标。3) 运用Mass ARRAY质谱仪检测OPG基因位点多态性。4) 多组间计量资料采用方差分析;BMD影响因素采用多元线性回归分析。结果:1) 与A组相比,C组、D组的空腹血糖(FPG)及HbAlc水平升高;D组、B组BMD (L1-4)及BMD (股骨颈)水平降低,(P Objective: To investigate the relationship between rs2073618 and rs3102735 polymorphism and mutation of osteoprotegerin (OPG) gene and bone metabolism in postmenopausal women with Type 2 diabetes mellitus (T2DM), so as to provide evidence for follow-up treatment. Methods: 1) A total of 200 subjects were selected from Shihezi area, all of which were postmenopausal women. According to Bone mineral density (BMD), the subjects were divided into normal control group (group A) and simple abnormal bone mass group (group B), and according to different glucose tolerance levels, they were divided into: simple T2DM (group C) and T2DM with abnormal bone mass (group D). 2) Measurement of bone, sugar, lipid, Glycated hemoglobin (HbA1c), BMD (L1-4), and BMD (neck of femur), respectively. 3) The polymorphism of OPG gene locus was detected by Mass ARRAY mass spectrometer. 4) Analysis of variance was used for measurement data among multiple groups;the influencing factors of BMD were analyzed by multiple linear regression. Results: 1) Compared with group A, fasting blood glucose (FPG) and HbAlc levels in groups C and D were increased. BMD (L1-4) and BMD (neck of femur) levels in groups D and B were decreased (P < 0.05). 2) In group D, Ca of rs2073618 mutant (GG/GC) was higher than that of wild type (CC), and Ca of rs3102735 mutant (CC/TC) was lower than that of wild type (TT). In group C, BMD (1-4) of rs2073618 mutant (GG/GC type) was higher than that of wild type (CC type), P < 0.05. 3) Multiple linear regression analysis: the in
