Abstract:
Objective:To investigate the change and clinical significance of serum Cathepsin K (Cathe K), 25 hydroxyvitamin D (25 (OH) D) and matrix gla protein (MGP) in postmenopausal patients with osteoporosis.Methods:Sixty postmenopausal patients with osteoporosis admitted to the hospital from May. 2020 to May. 2023 were selected as the study group, and 75 simple menopausal women were selected to the control group at the same period. Serum Cathe K, 25 (OH) D and MGP levels of the subjects were determined by enzyme-linked immunosorbent assay (ELISA). Bone metabolism indexes [N-terminal propeptide of typeⅠprecollagen (PINP), β isomer of the C-terminal telopep-tide of typeⅠcollagen ( β-CTX), bone alkaline phosphatase, (BALP) and osteocalcin (OC) ] were detected. The levels of Cathe K, 25 (OH) D and MGP and bone metabolism indexes were compared and their correlation was analyzed by Pearson correlation. The predictive value of Cathe K, 25 (OH) D and MGP levels in osteoporosis were analyzed and their effects on osteoporosis were analyzed by multiple Logistic regression. Results:Serum Cathe K in the study group was higher [ (27.27±4.82) μg/L vs. (20.84±4.17) μg/L], 25 (OH) D and MGP were lower [ (25.81±5.33) ng/mL, (7.26±1.53) ng/mL vs. (31.62±5.92) ng/mL, (10.75±2.31) ng/mL] ( t=5.22, P<0.001; t=4.88, P<0.05; t=7.58, P<0.05) ; The bone metabolism indexes PINP, β-CTX and OC in the study group were higher, while BALP was lower; Pearson correlation analysis showed that Cathe K was positively correlated with PINP, β-CTX and OC, and negatively correlated with BALP ( r=0.53, 0.45, 0.61, -0.75, P<0.05) ; 25 (OH) D was negatively correlated with PINP, β-CTX, OC, and positively correlated with BALP ( r=-0.41, -0.63, -0.43, 0.38, P<0.05) ; MGP was positively correlated with PINP, β-CTX and OC, and negatively correlated with BALP ( r=-0.77, -0.59, -0.61, 0.52, P<0.05) ; The area under the curve of serum Cathe K, 25 (OH) D and MGP for predicting osteoporosis were 0.715, 0.694 and 0.789, respectively. Conclusion:The abnormal levels of serum Cathe K, 25 (OH) D and MGP in postmenopausal patients with osteoporosis can be used to predict the occurrence of osteoporosis, and are closely related to the bone metabolism indexes of patients, which can provide a reference for the treatment of patients.
