目的探讨西格列汀联合二甲双胍对2型糖尿病伴骨质疏松患者骨转换标志物和骨密度的影响。方法选取2015年1月至2016年1月在本院明确诊断的2型糖尿病合并骨质疏松患者95例,随机分为3组,二甲双胍(metformin,M)+阿卡波糖组(acarbose,A)(M+A组)32例、西格列汀(sitagliptin,S)+阿卡波糖组(S+A组)31例、西格列汀+二甲双胍+阿卡波糖组(S+M+A组)32例,治疗随访48周。治疗前及治疗48周后测定体质量指数(body mass index,BMI)、血清空腹血糖(fasting plasma glucose,FPG)、餐后2小时血糖(2-hour postprandial plasma glucose,2h PG)、糖化血红蛋白(glycated hemoglobin A1c,Hb A1c)、25-羟基维生素D[25-hydroxyvitamin D,25(OH)D]、骨钙素(osteocalcin,OC)、I型胶原羧基端肽β特殊系列(β-cterminal cross-linked telpeptide,β-CTX)、骨特异碱性磷酸酶(bone specific alkaline phosphatase,b-ALP)。采用双能X线吸收测定法(dual energy X-ray absorptiometry,DXA)测定患者腰椎2~4及股骨颈的骨密度(bone mineral density,BMD)。比较各组治疗前后BMI、生化指标、骨转换指标和BMD的变化。结果 5例患者因药物不耐受而脱落,90例患者完成治疗随访,3组各30例。M+A组、S+A组、S+M+A组患者治疗前BMI[(25.1±1.5、25.2±1.6、25.1±1.7)kg/m2]、FPG[(8.45±0.81、8.43±0.83、8.46±0.91)mmol/L]、2h PG[(11.54±1.58、11.68±1.61、11.72±1.70)mmol/L]、Hb A1c[(7.92±0.71、7.95±0.73、7.94±0.75)%]比较差异无统计学意义(均P>0.05);治疗后BMI[(24.2±1.6、24.1±1.5、23.5±1.4)kg/m2]、FPG[(6.51±0.69、6.49±0.67、6.15±0.71)mmol/L]、2h PG[(9.10±0.72、9.18±0.89、8.11±0.51)mmol/L]、Hb A1c[(6.71±0.51、6.74±0.53、6.18±0.58)%]均较治疗前显著下降,差异有统计学意义(均P<0.05);治疗后S+M+A组与M+A组和S+A组BMI、FPG、2h PG、Hb A1c比较下降更显著,差异有统计学意义(均P<0.05);M+A组与S+A组BMI、FPG、2h PG、Hb A1c比较差异无统计学意义(均P>0.05)。M+A组、S+A组、S+M+A组患者治疗前b-ALP[(12.5±1.
Objective To evaluate the effects of sitagliptin and metformin on biomarkers of bone turnover and bone mineral density（BMD） in patients with type 2 diabetes（T2 DM） and osteoporosis（OP）. Methods Ninety-five patients diagnosed with T2 DM and OP at our hospital from January 2015 to January 2016 were randomly assigned into three groups,and were treated with metformin ＋ acarbose（M ＋ A group,n = 32）,sitagliptin ＋ acarbose（S ＋ A group,n = 31）,or metformin ＋ sitagliptin ＋acarbose（M ＋ S ＋ A group,n = 32） for 48 weeks. Body mass index（BMI）,serum fasting plasma glucose（FPG）,2-hour postprandial plasma glucose（2 h PG）,glycated hemoglobin A1 c（HbA1 c）,25-hydroxyvitamin D [25（OH） D],bone-specific alkaline phosphatase（b-ALP）,osteocalcin（OC） and β-c-terminal cross-linked telpeptide（β-CTX） were measured at baseline and at the end of the study. Bone mineral density（BMD） of lumbar spine（L2-4） and femoral neck were measured by dual energy Xray absorptiometry（DXA） at baseline and at the end of the study. Results Ninety patients completed the treatment,with 30 patients in each group. The mean values of BMI,FPG,2 hPG and HbA1 c were not significantly different among the three groups at baseline（all P〈0. 05）. The mean values of BMI,FPG,2 hPG and HbA1 c were significantly lower at the end of the study compared with the baseline values in the three groups（all P〈0. 05）. The mean values of BMI,FPG,2 hPG and HbA1 c were significantly lower in M ＋ S ＋ A group at the end of the study compared with M ＋ A group and S ＋ A group（all P〈0. 05）. The mean values of BMI,FPG,2 hPG and HbA1 c were not significantly different between M ＋ A group and S ＋ A group at the end of the study（all P〉0. 05）. The mean values of b-ALP,OC,β-CTX and BMD were not significantly different among the three groups at baseline（all P〉0. 05）. The mean values of b-ALP,OC and BMD were significantly higher and β-CTX were significantly lower at the end of
