Abstract:
Objective To investigate the application value of detection of serum miRNA-210,miRNA-23b in the patients with the femoral head necrosis.Methods The serum and clinical data of 135 patients with the internal fixation operation for the femoral neck fracture were collected.The patients were divided into the necrosis group (27 cases) and non-necrosis group (108 cases),used the real-time fluorescent quantitative PCR (Real time-PCR,RT-PCR) technology to detect serum miRNA-210,miRNA-23b expression in comparatively analysizing the relationship between the changes of serum miRNA 210,23b and occurrence of the femoral head necrosis.Results The serum microRNA-210,-23b expression in the necrosis group were 0.19±0.03,0.21±0.05,which in the non-necrosis group were 0.92±0.18 and 0.87±0.17.The serum microRNA-210,-23b expression in the necrosis group were significantly lower than those in the non-necrosis group,the difference had statistical significance (P＜0.01).The analysis results from the receiver-operating characteristic curve (ROC curve) showed that AUC of serum miRNA-210,miRNA-23b expression were 0.790 (95％CI:0.687～0.892,P=0.000) and 0.743 (95％CI:0.633～0.854,P=0.000),respectively.The sensitivity and specificity of miRNA-210 and miRNA-23b at the best threshold in diagnosis of the femoral head necrosis were 95.7％ and 93.9％,91.5％ and 92.3％,respectively.The analysis results showed that the serum miRNA-210,-23b expression had clinical significance in diagnosis of the femoral head necrosis.Conclusion Detection of serum miRNA-210,-23b expression can predict occurrence of the femoral head necrosis,estimate development condition of the desease.
