BackgroundTo investigate the value of serum Cyclophilin A(Cyp A) in evaluating the prognosis of patients with different severity of craniocerebral injury.MethodsThe clinical data of patients with craniocerebral injury treated in the Department of Emergency from July 2014 to August 2017 were collected. The patients were divided into survival group and death group, good neurological function group and poor neurological function group with 28-day prognosis and were divided into mild (13–15) group, moderate (9–12) group, and severe (3–8) group with Glasgow Coma Scale (GCS) score. Clinical parameters such as Cyp A and mortality in groups and the relationship between Cyp A and GCS score were compared and its predictive value for prognosis was analyzed with Binary Logistics regression, Cox proportional hazards model and kaplan-meier survival curve.ResultsIn a single-center retrospective study, 503 patients were enrolled, including 365 males and 138 females; serum Cyp A in the survival group was significantly smaller than the death group [18.7 (10.1, 51.5) ng/mL vs. 149.8 (79.5, 194.4) ng/mL, P < 0.005]. There were significant differences in mortality and Cyp A levels between patients with different severity of craniocerebral injury (P < 0.001). Serum Cyp A levels were negatively correlated with GCS scores in all patients with craniocerebral injury, mild, moderate, or severe craniocerebral injury (r = −0.844, r = −0.256, r = −0.540, r = −0.531, P < 0.001). Predictive value of Serum Cyp A level for all patients with craniocerebral injury, mild, moderate, and severe craniocerebral injury is 0.890, 0.789, 0.806, and 0.833, respectively. Logistics regression analysis showed that lactate (OR = 1.260, 95%CI: 1.023–1.551) and Cyp A (OR = 1.021, 95%CI: 1.011–1.031) were positively correlated with death (P < 0.05), Lactic acid (HR 1.115; 95%CI:1.001–1.243; P = 0.048), GCS score (HR 0.888; 95% CI: 0.794–0.993; P = 0.038), Cyp A levels (HR 1.009; 95% CI: 1.004–1.013; P < 0.001) had a significant effect on short-term mortality. Similar results were seen when neurologic function was used as the outcome. Kaplan-meier survival curve analysis found survival rate of patients with Cyp A level below the cut-off value was significantly higher.ConclusionSerum Cyp A has a certain predictive value for the prognosis of patients with different severity of craniocerebral injury. Among them, patients with severe craniocerebral injury have the highest predictive value and mild craniocerebral injury patients have the least. |
