Abstract:
Objective To investigate the expression of serum micro ribonucleic acid(miR)-423-5p and fer-ritin in elderly osteoporosis(OP)and their relationship with hip fragility fracture.Methods A total of 79 eld-erly OP patients admitted to the hospital from March 2020 to March 2024 were selected as the observation group,and 62 healthy elderly patients with complete physical examination records and reports were selected as the control group during the same period.Patients in the observation group were divided into fracture group(42 cases)and non-fracture group(37 cases)according to the occurrence of hip fragility fracture.Serum miR-423-5p and ferritin levels were compared between the observation group and the control group and between the fracture group and the non-fracture group.The difference of bone mineral density(BMD)at different sites between the fracture group and the non-fracture group was compared.The correlation between serum miR-423-5p and ferritin and BMD at different sites was analyzed by Pearson,and the predictive value of serum miR-423-5p and ferritin in elderly hip fragility fractures was analyzed by receiver operating characteristic(ROC)curve.Results Serum miR-423-5p and ferritin in observation group were higher than those in control group,the differences were statistically significant(P＜0.05).The levels of serum miR-423-5p and ferritin in frac-ture group were higher than those in non-fracture group,and the differences were statistically significant(P＜0.05).Greater trochanteric BMD and total hip BMD in the non-fracture group were higher than those in the fracture group,and the differences were statistically significant(P＜0.05).According to Pearson correlation analysis,serum miR-423-5p and ferritin levels in elderly OP patients were negatively correlated with BMD de-tected in lumbar spine,femoral neck,greater trochanter,intertrochanter and total hip(P＜0.05).ROC curve analysis results showed that the sensitivity,specificity and the area under the curve(AUC)of serum miR-423-5p combined with ferritin were 0.786,0.892 and 0.818(95％CI:0.715-0.912),which were higher than the AUC predicted by the two alone and had higher predictive value(P＜0.05).Conclusion The combination of serum miR-423-5p and ferritin levels can predict the risk of hip fragility fracture in elderly OP patients.
