Abstract:

Objective

To explore the relationship between serum levels of soluble T cell immunoglobulin and mucin domain-3 (sTIM-3), and its ligand Galectin-9 (Gal-9) and carcinoembryonic antigen-related cell adhesion molecule-1 (CEACAM-1) in patients with traumatic brain injury (TBI) and the degree of brain injury and prognosis.

Methods

A total of 120 patients with TBI admitted to the Third Department of Neurosurgery of Handan Central Hospital from February 2022 to February 2023 were selected as the observation group, and 120 healthy subjects who underwent physical examination during the same period were selected as the control group.The levels of sTIM-3, Gal-9 and CEACAM-1 were compared between the two groups.The TBI patients were graded according to the preoperative GCS score (severe type, moderate type and mild type), and the differences of serum sTIM-3, Gal-9 and CEACAM-1 levels in patients with different TBI degrees were explored.After 1 month of treatment, the prognosis of TBI patients was evaluated according to the GOS score.Univariate and multivariate Logistic regression analysis was used to analyze the influencing factors of poor prognosis in TBI patients.The receiver operating characteristic (ROC) curve was used to analyze the predictive value of the influencing factors on the prognosis of TBI patients.

Results

In the observation group, there were 36 cases of severe type, 42 cases of moderate type and 42 cases of mild type.Compared with the control group, the levels of sTIM-3, Gal-9 and CEACAM-1 in the observation group increased, and the expression level increased with the increase of TBI degree, the differences were statistically significant (P<0.05).After 1 month of treatment, 76 cases had good prognosis and 44 cases had poor prognosis.Univariate analysis showed that the levels of serum sTIM-3,Gal-9,CEACAM-1 and GCS score in patients with poor prognosis were higher than those in patients with good prognosis (P<0.05).Multivariate Logistic regression analysis showed that sTIM-3, Gal-9, CEACAM-1 and GCS score were independent factors affecting the prognosis of TBI patients (P<0.05).ROC analysis showed that the area under the curve (95%CI) of serum sTIM-3,Gal-9, CEACAM-1 and GCS score alone and in combination were 0.744, 0.706, 0.697, 0.739 and 0.823(0.724-0.921), respectively, the diagnostic efficiency of combined application was higher than that of each index alone (P<0.05).

Conclusion

Serum sTIM-3 and its ligands Gal-9 and CEACAM-1 can be used as new and meaningful molecular markers to evaluate the severity and prognosis of TBI patients.
