摘　　要：目的 :探讨 2型糖尿病患者骨代谢生化指标的临床意义。方法 :对 4 0例 2型糖尿病患者及 31例正常人进行血骨钙素 (BGP)、钙 (Ca)、碱性磷酸酶 (ALP) ;尿脱氧吡啶啉 (DPD)、Ca、肌酐 (Cr)测定。结果 :糖尿病组血清BGP较正常对照组明显降低 (P <0 0 5 ) ;尿DPD/Cr比值 ,Ca/Cr比值显著高于正常对照组 (P <0 .0 5 ,P <0 .0 5 ) ;血清Ca、ALP两组无统计学差异。结论 :2型糖尿病患者骨代谢异常引发骨量减少、骨质疏松与骨形成减少和骨吸收增加有关 ;血BGP、尿DPD/Cr、Ca/Cr可作为早期诊断糖尿病骨量减少、骨质疏松敏感的骨代谢生化指标。Objective To investigate the clinical significance of changes of levels of biochemical markers of bone metabolism in patients with type 2 diabetes mellitus. Methods Serum osteocalcin (BGP, with RIA)、 Ca、 alkaline phosphatase (ALP) and random specimen urinary deoxypyridinoline (DPD, with chemiluminescence assay)、 Ca、 creatinine levels were measured in 40 patients with type 2 diabetes mellitus and 31 controls. Results Serum BGP levels in diabetic patients were much lower than those in the controls ( P <0.05); while urinary DPD/Cr ratio and Ca/Cr ratio were significantly higher in the patients than those in the controls ( P <0.05, P <0.05). Serum Ca and ALP levels were about the same in the two groups. Conclusion Loss of bone mass in diabetic patients are due to both decreased bone formation and increased bone resorption. Determination of the levels of the biochemical markers of bone metabolism (BGP, DPD ……) could be applied for early detection of osteoporosis.
