Abstract:
Objective To explore the changes of serum angiopoietin-like protein 4(ANGPTL4)and NOD-like receptor protein 3(NLRP3)levels after traumatic brain injury(TBI)and their diagnostic value for sec-ondary massive cerebral infarction.Methods A total of 100 TBI patients admitted to the hospital from Au-gust 2019 to August 2021 were enrolled as the TBI group,meantime,100 healthy people in the hospital were enrolled as the control group.The serum levels of ANGPTL4 and NLRP3 were detected by enzyme-linked im-munosorbent assay(ELISA).The clinical characteristics of TBI patients with and without secondary massive cerebral infarction were compared.Receiver operating characteristic(ROC)curve was applied to analyze the serum levels of ANGPTL4 and NLRP3 on their diagnostic value for TBI patients with secondary massive cere-bral infarction.Multivariate Logistic regression analysis was applied to analyze the factors affecting the occur-rence of secondary massive cerebral infarction in TBI patients.Results The serum ANGPTL4 level in TBI group was lower than that in the control group,and the serum NLRP3 level was higher than that in the con-trol group(P<0.05).There were obvious differences in proportion of brain hernia,proportion of subarach-noid hemorrhage,serum levels of ANGPTL4 and NLRP3 between patients with secondary massive cerebral infarction and patients without secondary massive cerebral infarction(P<0.05).ROC curve analysis showed that the area under the curve(AUC)of serum ANGPTL4 and NLRP3 in diagnosing secondary massive cere-bral infarction in TBI patients was 0.792 and 0.812 respectively,with sensitivity of 77.80%and 83.30%re-spectively,and specificity of 86.60%and 64.60%respectively.The sensitivity,the specificity and AUC of the combined detection were 83.30%,82.90%and 0.867 respectively.Multivariate Logistic regression analysis showed that serum NLRP3 level was a risk factor for TBI patients with secondary massive cerebral infarction(P<0.05).After treatment,it was found that serum ANGPTL4 level increased and NLRP3 level decreased in TBI patients(P<0.05).Conclusion The serum level of ANGPTL4 in TBI patients decreases,while the level of NLRP3 increases,and the level of ANGPTL4 in the serum of patients with secondary massive cerebral in-farction decreases and the level of NLRP3 increases,both of them are of great significance in the diagnosis of secondary massive cerebral infarction in TBI patients.
