摘要:

目的 探讨骨代谢标志物[β胶原特殊序列(β-CTX)、总Ⅰ型胶原氨基端延长肽(tP1NP)、骨钙素(BGP)]和miR-100、miR-148a在骨质疏松性骨折(OF)中的临床价值。方法 选取2023年1月—2025年11月开封市人民医院老年骨质疏松症(OP)患者167例(OP组)和健康体检者80名(正常对照组)。根据是否发生脆性骨折将OP患者分为骨折组(82例)和未骨折组(85例)。检测所有研究对象的骨密度、骨代谢标志物(β-CTX、tP1NP、BGP)和miR-100、miR-148a。采用Spearman相关分析评估各项目之间的相关性。采用多因素Logistic回归分析评估OF发生的影响因素;采用受试者工作特征(ROC)曲线评价各项指标单项检测和联合检测诊断OF的效能。结果 OP组β-CTX、tP1NP、BGP水平和miR-100、miR-148a相对表达量均高于正常对照组(P<0.001)。β-CTX、tP1NP、BGP水平与miR-100、miR-148a表达均呈正相关(P<0.001)。骨折组β-CTX、tP1NP、BGP水平和miR-100、miR-148a相对表达量均高于未骨折组(P<0.001)。β-CTX、tP1NP、BGP、miR-100、miR-148a升高均是OF发生的危险因素(P<0.05)。β-CTX+tP1NP+BGP、β-CTX+tP1NP+BGP+miR-100、β-CTX+tP1NP+BGP+miR-148a、β-CTX+tP1NP+BGP+miR-100+miR-148a诊断OF的曲线下面积(AUC)分别为0.899、0.914、0.919、0.930。结论 OP患者β-CTX、tP1NP、BGP水平和miR-100、miR-148a表达均升高,OF患者升高更为显著。骨代谢标志物β-CTX、tP1NP、BGP联合miR-100、miR-148a检测对OF有较高的诊断效能。

Abstract:

Objective To investigate the clinical value of bone metabolism markers [beta-C-terminal telopeptide of type Ⅰ collagen(β-CTX),total type Ⅰ collagen N-terminal propeptide(tP1NP),bone glaprotein(BGP)] and miR-100,miR-148a in the occurrence of osteoporotic fractures(OF). Methods A total of 167 elderly patients with osteoporosis(OP) and 80 healthy subjects from January 2023 to November 2025 in Kaifeng People's Hospital were enrolled. All the OP patients were classified into fracture group(82 cases) and non-fracture group(85 cases). Bone mineral density,bone metabolism markers(β-CTX,tP1NP,BGP) and miR-100,miR-148a were determined. Spearman correlation analysis was used to evaluate the correlations among the indicators. Multivariate Logistic regression analysis was used to evaluate the influencing factors of OF. Receiver operating characteristic(ROC) curve was used to evaluate the efficacy of single and combined determinations of each indicator in diagnosing OF. Results The levels of β-CTX,tP1NP,BGP and the relative expression levels of miR-100 and miR-148a in OP group were higher than those in healthy control group(P<0.001). The levels of β-CTX,tP1NP and BGP were positively correlated with the expression of miR-100 and miR-148a(P<0.001). The levels of β-CTX,tP1NP,BGP and the relative expression levels of miR-100 and miR-148a in fracture group were higher than those in non-fracture group(P<0.001). The increase in β-CTX,tP1NP,BGP,miR-100 and miR-148a were risk factors for OF(P<0.05). The areas under curves(AUC) of β-CTX+tP1NP+BGP,β-CTX+tP1NP+BGP+miR-100,β-CTX+tP1NP+BGP+miR-148a and β-CTX+tP1NP+BGP+miR-100+miR-148a combined determinations for diagnosing OF were 0.899,0.914,0.919 and 0.930,respectively. Conclusions The levels of β-CTX,tP1NP,BGP and the expression of miR-100 and miR-148a are increased in OP patients,and the increase is more significant in OF patients. The combined determination of β-CTX,tP1NP,BGP and miR-100,miR-148a has high clinical efficiency for OF.
