Abstract: Objective To explore the serum levels of VILIP-1 and Cav-1 in cases with severe craniocerebral injury undergoing decompression and their effects on the prognosis.Methods 108 patients with severe craniocerebral injury who were treated in our hospital from July 2019 to July 2022 were selected as the study group,and 120 healthy people who came to our hospital for physical examination were selected as the health group.All cases were followed up for 6 months,and were divided into good prognosis group (GOS=45 points,n=82) and poor prognosis group (GOS=13 points,n=26) according to GOS.The levels of serum VILIP-1 and Cav-1 were detected by ELISA.The diagnostic value of serum VILIP-1 and Cav-1 on the prognosis of patients was evaluated by the ROC curve.Multivariate logistic regression analysis was used to explore the prognostic factors of patients.Results The levels of serum VILIP-1 and Cav-1 in study group were higher than those in healthy group (P<0.05).The levels of serum VILIP-1 and Cav-1 in case with poor prognosis were higher than those in cases with good prognosis (P<0.05).The AUC (95%CI) of serum VILIP-1 and Cav-1 to predict the prognosis of patients was 0.848(0.797~0.899) and 0.817(0.766~0.868).The AUC(95%CI) of the combined detection was 0.905 (0.854~0.956).The time from injury to admission,admission GCS score,history of diabetes,admission pupillary reaction,preoperative brain midline displacement and postoperative complications in good prognosis group were different from those in poor prognosis group (P<0.05).Preoperative midline displacement≥5mm (OR=2.467,95%CI:1.619~3.760),postoperative complications≥ 2(OR=2.321,95%CI:1.544~3.489),VILIP-1≥10.37ng/ml (OR=3.367,95%CI:2.087~5.432),and Cav-1 ≥ 32.28μg/L (OR=2.770,95%CI:1.786~4.298) were risk factors for prognosis in patients(P<0.05).Conclusion Serum VILIP-1 and Cav-1 can be used as biological indicators to predict the prognosis of patients with severe brain injury after decompression,and the increase of serum VILIP-1 and Cav-1 levels are risk factors for prognosis.
