Objective: To explore the relationship study between serum myelin basic protein (MBP), lactate dehydrogenase (LDH) to albumin (ALB) ratio (LAR), ALB to globulin (GLB) ratio (AGR) and postoperative brain injury and prognosis in patients with glioma. Methods: 90 cases of patients with glioma who received surgical treatment admitted to Department of Neurosurgery, Affiliated Hospital of Xuzhou Medical University from January 2017 to June 2019 were retrospectively selected, and they were divided into mild brain injury group with 51 cases, moderate brain injury group with 24 cases and severe brain injury group with 15 cases according to the score of the Glasgow Coma Scale (GCS) after surgery. After 3 years of follow-up, they were divided into death group and survival group according to the prognosis. Clinical data were collected, and serum MBP, LAR and AGR before surgery were detected. Spearman correlation was used to analyze the correlation between GCS score and serum MBP, LAR and AGR in patients with glioma, and multivariate logistic regression was used to analyze the influencing factors of death in patients with glioma. Results: Serum MBP and LAR in the mild, moderate and severe brain injury groups were increased successively, while AGR was decreased successively (P< 0.05). Spearman correlation analysis showed that postoperative GCS score in patients with glioma was negatively correlated with serum MBP and LAR, and positively correlated with AGR (all P<0.05). After 3 years of follow-up, the mortality rate of 90 cases of patients with glioma was 35.56% (32/90). Multivariate logistic regression analysis showed that World Health Organization (WHO) grade III, incomplete resection range, decreased postoperative GCS score and elevated MBP and LAR were the independent risk factors for death in patients with glioma, and elevated AGR was the independent protective factor (P<0.05). Conclusion: Serum MBP, LAR and AGR in patients with glioma are closely related to postoperative brain injury and poor prognosis, which may be used as indicators to evaluate postoperative brain injury and prognosis in patients with glioma.
