| 目的研究胶东半岛老年性骨质疏松症（OP)患者骨代谢生化指标与骨密度（BMD )的相关关 系，探讨骨代谢生化指标对早期诊断OP的临床意义。方法采用双能X线骨密度仪（DEXA )对胶 东半岛沿海地区多中心多阶段整群抽样M7名40耀89岁居民进行腰椎（蕴2_源)BMD测量。采用酶联 免疫法（ELISA )分别测定血抗酒石酸酸性磷酸酶（TRAP-5b )、1型胶原C端肽（CTX )、骨特异性碱性 磷酸酶（BALP)、骨钙素（BGP)、降钙素（CT)、25-羟基维生素D[ 25( OH )D ]以及血钙（Ca )和磷（P ) 并进行比较，应用SPSS 13.0软件进行统计分析。结果 OP患者各部位BMD明显低于正常组（均P <0.01 )。老年男性BMD与骨形成和骨吸收指标呈现降低趋势。其中，OP组较对照组BGP、TRAP- 5b和25( OH )D明显下降（P <0. 05 )，而血CTX和BALP较对照组升高。老年女性血TRAP-5b、CTX、 BALP和BGP在OP组显著升高（均P <0.01 )，而CT和25( OH )D明显降低。各组研究对象骨代谢 生化标志物均有统计学意义。结论骨代谢生物指标作为OP的监测指标，比BMD更加灵敏、特异。 能够早期反映患者骨代谢水平，对指导OP的早期预防及治疗有重要意义。 |

| Objective To invesLigate the correlation hetween biochemical markers of bon^ meLaboli^m and bon^ mineral density( BMD )in senile osteoporosis paLients in Jiaodong Peninsula of Shandong and to explore the clinical value of biochemical markers of bone metabolism on the early diagnosis of primary osLeoporosis. Methods BMD of the lumbar vertebrae 2-4 of 297 40-89 years old subjecLs in Jiaodong peninsula， sampled using the mLiiti-center and multi-sLage sampling method， was measured using dual energy X-ray absorptiometry ( DEXA ). Serum TRAP-5b，CTX，BA LP，BGP，CT，25( OH ) D，C a，and P were deLected using ELISA. SPSS 13. 0 was used to analyze the data sLaListicaiiy. Results BMD of osteoporosis patients was significantly lower than that of the control paLients. BMD and indexes of bone formation and absorption in senile males showed a decreasing trend. BGP，TRAP，and 25( OH ) D in senile males in osteoporosis group were significantly lower than those in non-osLeoporosis ones ( P < 0. 05 ). Serum CTX and BALP of senile males in Lhe osLeoporosis group were significanLly higher Lhan Lhose in Lhe non-osLeoporosis group. Serum TRAP-5b，CTX， BALP，and BGP in females in osLeoporosis group were significanLly higher Lhan Lhose of Lhe conLrols ( P <0. 01 ). Serum CT and 25( OH ) D were significantly lower than those of the controls. The differences of all biochemical markers of bone meLabolism were sLaListically significant. Conclusion The serum biochemical indexes of bone metabolism can be used as the monitor index of OP. The applicaLion of these indexes is more sensitive and specific Lhan BMD. It can reflecL the bone meLabolism in the early stage， and has great significance in the prevention and treaLment osteoporosis. |
