Abstract:
OBJECTIVE:To investigate the relationship between serum C1q/tumor necrosis factor-related protein-3(CTRP3) and peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α) on predictive value of expression level on fracture healing.
METHODS:From January 2019 to January 2020, 80 patients with traumatic tibial plateau fractures were treated by internal fixation with support plates through the posterior approach of the knee joint. The patients were followed up for 12 months. According to the criteria for delayed fracture healing, the patients were divided into two groups:54 patients in fracture healing group included 24 males and 30 females, aged 29 to 75 years old with an average of (52.36±13.17) years;In the delayed healing group, there were 26 cases, 13 males and 13 females, aged from 29 to 75 with an average od (53.82±13.52) years. The serum levels of CTRP3, PGC-1αand 25 hydroxyvitamin D3[25(OH)D3] in patients with traumatic fracture were detected by enzyme-linked immunosorbent assay(ELISA);Blood phosphorus and calcium levels were measured by automatic biochemical analyzer, and the product of calcium and phosphorus was calculated;Pearson's method was used to analyze the correlation between serum CTRP3, PGC-1αand bone biochemical indexes in patients with delayed union one week after operation;The predictive value of serum levels of CTRP3 and PGC-1αon traumatic fracture healing was analyzed by receiver operating characteristic curve(ROC curve).
RESULTS:PGC-1α, calcium phosphorus product and 25(OH)D3 in the fracture healing group were higher than those in the delayed healing group at 1 and 4 weeks after operation(P<0.05). Serum CTRP3 was positively correlated with PGC-1α(r=0.637, P<0.05) and positively correlated with calcium phosphorus product and 25(OH)D3(P<0.05). The areas under the curve(AUC) of serum ctrp3 and PGC-1α levels in predicting traumatic fracture healing were 0.845 and 0.855, respectively. The cutoff values were 188.678 pg/ml and 2.697 ng/ml, respectively. The specificity was 96.2% and 80.8%, and the sensitivity was 53.7% and 77.8%;The predicted AUC was 0.904, the specificity was 88.5%, and the sensitivity was 81.5%.
CONCLUSION:The serum levels of CTRP3 and PGC-1 in patients with delayed union of traumatic fracture at 1 and 4 weeks after operation α The expression level is of certain reference value to predict the fracture healing status of patients.
