重庆地区骨质疏松患者25-羟维生素D与骨代谢的相关性分析

目的对25-羟维生素D和甲状旁腺激素(PTH)、N端骨钙素(N-MID)、降钙素(CT)、骨碱性磷酸酶(BALP)的相关性进行统计学分析,并探讨其在临床疾病的诊断、预防及治疗中的应用价值。方法收集2014年1-9月重庆医科大学附属第二医院住院患者411例,其中女316例,男95例;平均(69.29±12.21)岁。采用免疫电化学发光法检测住院患者25-羟维生素D、PTH、N-MID、CT、BALP的水平,探讨骨质疏松患者25-羟维生素D与骨代谢标志物的关系。结果25-羟维生素D与PTH、BALP均呈负相关关系(P0.05),而与CT、N-MID则无显著相关(P0.05)。回归分析显示,25-羟维生素D与骨代谢标志物回归方程为Y=19.02-0.066PTH-0.09BALP。结论骨质疏松患者25-羟维生素D水平的升高、降低与PTH、BALP均有一定相关性,通过对这些指标的检测,可以为临床骨质疏松患者的诊断、预防和控制提供基础数据。

The Relationship between vitamin D and bone metabolism markers in osteoporosis patients of Chongqing

Objective To analyze the statistical correlation between 25-hydroxyl vitamin D and bone metabolism parameters in-cluding parathyroid hormone(PTH),N-terminal osteocalcin (N-MID),calcitonin(CT),bone alkaline phosphatase(BALP),and dis-cuss the significance in clinical diagnosis,prevention and treatment.Methods 411 cases of hospitalized patients were collected from January to September in 2014,including 316 women,95 men,age arranged from 37 to 96,the average age was(69.29±12.21).Use electro chemiluminescence immunoassay(ECLIA)method to detect the levels of 25-hydroxyl vitamin D,PTH,N-MID,CT,and BALP in hospitalized patients and explore the relationship of 25-hydroxyl vitamin D and serum bone markers in osteoporosis pa-tients.Results It was showed that vitamin D and PTH,BALP were negative correlation(P <0.05);There was no significant corre-lation between calcitonin and N-terminal osteocalcin(N-MID)(P >0.05 ).Regression analysis showed that regression equation for vitamin D and blood bone markers was:Y =19.02-0.066PTH-0.09BALP.Conclusion There was some correlation between 25-hydroxyl vitamin D and PTH,BALP in patients with osteoporosis.By taking a combination test of these markers,it can provide some basic data for clinical osteoporosis diagnosis,prevention and control.
