Abstract:
Objective:To investigate the diagnostic value of serum CircRNA_0048211 expression level in postmenopausal osteoporosis (PMOP) and its correlation with bone-specific alkaline phosphatase (BALP), osteopontin (OPN), procollagen type I N-terminal propeptide (PINP) and β-crosslaps (β-CTX). Methods:Data of postmenopausal women who underwent physical examination in our hospital from January 2019 to December 2021 were collected. All subjects were measured bone mineral density (BMD) by dual-energy X-ray absorptiometry and divided into PMOP group, decreased bone mass group and normal bone mass group according to BMD level. The serum CircRNA_0048211, BALP, OPN, PINP and β-CTX levels were compared in each group. Binary logistic regression was used to analyze the risk factors of PMOP, the receiver operating characteristic curve (ROC) was drawn to analyze the diagnostic value of CircRNA_0048211, BALP, OPN, PINP and β-CTX on PMOP. The correlation between CircRNA_0048211 expression level and BALP, OPN, PINP and β-CTX was analyzed by Pearson correlation analysis. Results:A total of 218 patients were included in this study. Age is 60.52±6.83 years (range, 47-76 years), body mass index is 24.27±2.28 kg/m 2 (range, 22.18-25.73 kg/m 2) and menopausal time is 10.16±4.25 years (range, 2.30-21.80 years). There were 40 cases in PMOP group, 97 cases in osteopenia group and 81 cases in normal bone mass group. The serum CircRNA_ 0048211, BALP, OPN, PINP and β-CTX was significantly different between PMOP group, osteopenia group and normal group ( F=21.15, P<0.001; F=12.52, P<0.001; F=17.86, P<0.001; F=14.32, P<0.001; F=15.52, P<0.001). The serum CircRNA_0048211 level in PMOP group (0.37±0.08) were significantly lower than that of osteopenia group (1.05±0.46) and normal bone mass group (1.73±0.81), the difference was statistically significant ( P<0.05). The levels of BALP (28.42±7.35 μg/L), OPN (17.28±7.30 ng/ml), PINP (58.40±14.37 ng/ml) and β-CTX (1.52±0.28 μg/L) in PMOP group were significantly higher than those in osteopenia group (22.61±5.93 μg/L, 11.95±5.64 ng/ml, 49.16±11.24 ng/ml, 0.81±0.17 μg/L) and normal bone mass group (16.30±4.18 μg/L, 7.62±3.25 ng/ml, 35.48±7.12 ng/ml, 0.37±0.10 μg/L), the difference was statistically significant ( P<0.05). Binary logistic regression analysis showed that decreased CircRNA_0048211 expression level [ OR=3.53, 95% CI (2.73, 10.32)] was a risk factor for the occurrence of PMOP ( P<0.001). ROC curve showed that CircRNA_0048211≤0.76 has a diagnostic significance on PMOP, and its combination of BALP, OPN, PINP and β-CTX has the highest AUC [0.95, 95% CI (0.89, 1.00)] in diagnosing PMOP. Correlation analysis showed that CircRNA_0048211 expression level were negatively correlated with BALP, OPN, PINP and β-CTX ( r=-0.46, P<0.001; r=-0.80, P<0.001; r=-0.81, P<0.001; r=-0.69, P<0.001). Conclusion:The CircRNA_0048211 showed low expression in PMOP, which was negatively correlated with BALP, OPN, PINP and β-CTX. The combination of these five factors has certain clinical value in the diagnosis of PMOP.
