Abstract
OBJECTIVE T cell immunoglobulin and mucin domain-3 (Tim-3) may be implicated in neuroinflammation. Herein, we attempted to discern the role of serum soluble (s) Tim-3 as an inflammatory prognostic biomarker of severe traumatic brain injury (sTBI). METHODS In this prospective observational study of 112 sTBI patients and 112 controls, serum sTim-3 levels were determined, Rotterdam computed tomography (CT) classification and Glasgow coma scale (GCS) were selected as the two severity indicators, serum C-reactive protein (CRP) was regarded as an inflammatory biomarker, and poor prognosis was referred to as extended Glasgow outcome scale (GOSE) scores 1-4 at 180 days after trauma. RESULTS Serum sTim-3 levels were markedly higher in patients than in controls (median, 4.2 ng/mL versus 0.7 ng/mL; P<0.001). Serum sTim-3 levels of patients were independently related to Rotterdam CT scores (β=1.126), GCS scores (β=-0.589), serum CRP levels (β=0.155) and GOSE scores (β=-0.211). Serum sTim-3 appeared as an independent predictor of post-traumatic 180-day mortality (odds ratio=1.289), overall survival (hazard ratio=1.208) and poor prognosis (odds ratio=1.293). Serum sTim-3 levels discriminated patients at risk of post-injury 180-day mortality and poor prognosis with areas under curve (AUCs) at 0.753 and 0.782, respectively. Serum sTim-3 levels combined with GCS scores and Rotterdam CT scores (AUC=0.869) exhibited significantly higher AUC than Rotterdam CT scores (P=0.026), but not than GCS scores (P=0.181) for death prediction and their combination (AUC=0.895) had significantly higher AUC than GCS scores (P=0.036) or Rotterdam CT scores (P=0.005) for outcome prediction. CONCLUSION Elevated serum sTim-3 levels, in close correlation with traumatic severity and inflammation, are substantially associated with long-term death and poor outcome, indicating that serum sTim-3, as an inflammatory biomarker, may be of clinical significance in severity assessment and prediction of prognosis following sTBI.

Abstract
BACKGROUND Hypoxia-inducible factor 1alpha (HIF-1α) is implicated in the cell's response to hypoxia. We investigated whether serum HIF-1α concentrations are correlated with the severity and clinical outcome of severe traumatic brain injury (sTBI). METHODS Serum HIF-1α concentrations were quantified in 104 sTBI patients and 80 healthy controls. Trauma severity was assessed using Glasgow coma scale (GCS). Glasgow outcome scale (GOS) score of 1-3 at post-trauma 90 days was defined as a poor outcome. Multivariate analyses were performed to discern the relationship between serum HIF-1α concentrations and outcome. RESULTS Patients displayed significantly higher serum HIF-1α concentrations than controls (median, 294.9 versus 102.7 pg/ml). HIF-1α concentrations were intimately related to GCS scores (r = -0.62) and GOS scores (r = -0.64). 48 patients (46.2%) experienced a poor outcome. Serum HIF-1α concentrations > 280.2 pg/ml significantly distinguished patients with the development of poor outcome with 77.1% sensitivity and 69.6% specificity (AUC, 0.750; 95% CI: 0.655-0.829). Serum HIF-1α concentrations > 280.2 pg/ml emerged as an independent predictor for poor outcome (OR: 4.179; 95% CI: 1.024-17.052). CONCLUSIONS Serum HIF-1α concentrations are tightly associated with trauma severity and poor 90-day outcome, substantializing serum HIF-1α as a promising prognostic biomarker for sTBI.

Abstract
BACKGROUND CXC chemokine ligand-12 (CXCL12) is associated with brain inflammation. We attempted to discern whether serum CXCL12 is a promising predictor for in-hospital major adverse events (IMAEs) after traumatic brain injury (TBI), including death, acute lung injury, acute traumatic coagulopathy, progressive hemorrhagic injury and posttraumatic cerebral infarction. METHODS In this prospective, observational study, serum CXCL12 levels were quantified among 117 severe TBI patients. We investigated the relation of CXCL12 levels to IMAEs using a multivariate analysis. RESULTS Median value of serum CXCL12 concentrations was substantially higher in patients with IMAEs than in other remainders (21.1 vs. 11.6 ng/ml). With an increasing number of IMAEs, serum CXCL12 concentrations were significantly increased (r = 0.702). Serum CXCL12 independently predicted IMAEs (odds ratio, 1.253; 95% CI, 1.100-1.428). Serum CXCL12 concentrations discriminated risk of IMAEs with area under receiver operating characteristic curve of 0.759 (95% CI, 0.672-0.834), its concentrations >16.0 ng/ml distinguished IMAEs with 83.9% sensitivity and 67.2% specificity and its combination with Glasgow coma scale scores produced the best predictive ability compared with each one alone (p = 0.0116 or 0.0004). CONCLUSION Serum CXCL12 concentrations are independently associated with IMAEs following TBI, substantializing serum CXCL12 as a useful prognostic biomarker for head trauma patients.

Abstract
BACKGROUND Serum glucose and potassium ratio (GPR) was recently found to be related to outcome of aneurysmal subarachnoid hemorrhage. This retrospectively study was to investigate the association of serum GPR with mortality in severe traumatic brain injury (sTBI). METHODS Clinical data were retrospectively reviewed of isolated sTBI patients admitted within 12 h after trauma between January 2014 and January 2019. We analyzed relationships between admission serum GPR and post-traumatic 30-day mortality in addition to admission Glasgow coma scale (GCS) scores. Discriminative ability was evaluated using area under receiver operating characteristic curve (AUC). RESULTS A total of 146 patients, of whom 37 (25.3%) died within 30 days following trauma, were included. Admission serum GPR emerged as an independent predictor for 30-day mortality (odds ratio, 5.256; 95% confidence interval (CI), 1.111-14.856) and overall survival (hazard ratio, 4.822; 95% CI, 1.157-12.870), with an AUC of 0.777 (95% CI, 0.693-0.835), which was equivalent to that of GCS scores (AUC, 0.831; 95% CI, 0.760-0.888; P = 0.179). There was a significant correlation between admission serum GPR and GCS scores (r2 = 0.293). CONCLUSIONS Serum GPR in cases of sTBI is substantially associated with trauma severity and 30-day mortality. Therefore, the potential value of serum GPR for predicting short-term mortality of sTBI patients is favorable.

Abstract
BACKGROUND Platelet activation is implicated in secondary brain injury following traumatic brain injury (TBI). C-type lectin-like receptor 2 (CLEC-2) is extensively expressed on platelets and participates in platelet activation. We investigate dthe prognostic significance of plasma CLEC-2 in TBI patients. METHODS One hundred and six patients with isolated severe blunt TBI and 106 healthy controls were prospectively investigated. Plasma CLEC-2 concentrations were detected and Glasgow coma scale (GCS) scores were recorded. The relationship between plasma CLEC-2 concentrations and 30-day mortality in addition to overall survival was determined using multivariate models. RESULTS Patients exhibited a substantially higher concentration of plasma CLEC-2 than healthy controls. Among patients, plasma CLEC-2 concentrations were remarkably increased in the GCS scores- and Rotterdam computerized tomography classification- dependent manner. As compared with survivors within posttraumatic 30 days, plasma CLEC-2 concentrations were remarkably raised in non-survivors. Rising plasma CLEC-2 concentration was independently associated with an enhanced risk of 30-day mortality and short overall survival time. Plasma CLEC-2 concentrations had a significantly high area under receiver operating characteristic curve for predicting 30-day mortality. CONCLUSIONS Incremental plasma CLEC-2 concentrations are intimately related to increasing trauma severity, in close association with increased 30-day death, indicating the prognostic role of plasma CLEC-2 in TBI.

Abstract
BACKGROUND Secreted protein acidic and rich in cysteine-like 1 (SPARCL1) regulates synaptic stability with upregulation throughout axonal regeneration. Our study aims to determine the correlation of serum SPARCL1 concentrations with the severity and in-hospital mortality of severe traumatic brain injury (sTBI). METHODS A total of 102 consecutively recruited patients admitted for sTBI and 102 randomly selected healthy controls were included in this observational prospective study. Serum SPARCL1 concentrations were measured and correlated with Glasgow coma scale (GCS) scores and in-hospital mortality using multivariate analysis. RESULTS Compared with controls (median, 0.22 ng/ml; interquartile range, 0.19-0.41 ng/ml), patients had significantly higher SPARCL1 concentrations (median, 3.29 ng/ml; interquartile range, 1.88-4.37; P < 0.001). There was an independently correlation between SPARCL1 concentrations and GCS scores (t = -7.011, P < 0.001). We found a high area under receiver operating curve (AUC) of serum SPARCL1 concentrations to predict in-hospital mortality (AUC, 0.822; 95% confidence interval, 0.734-0.891). In the multiple logistic regression analysis, serum SPARCL1 concentrations >3.29 ng/ml was independently associated with in-hospital mortality (odds ratio = 10.052, 95% confidence interval = 1.918-52.686, P = 0.006). CONCLUSIONS The novel findings of our study are that sTBI patients had an increase of serum SPARCL1 concentrations, and that there is an association between high serum SPARCL1 concentrations and sTBI mortality or trauma severity.

Abstract
INTRODUCTION Recently, we reported that high levels of resistin are present in the peripheral blood of patients with intracerebral hemorrhage and are associated with a poor outcome. However, not much is known regarding the change in plasma resistin and its relation with mortality after traumatic brain injury (TBI). Thus, we sought to investigate change in plasma resistin level after TBI and to evaluate its relation with disease outcome. METHODS Fifty healthy controls and 94 patients with acute severe TBI were included. Plasma samples were obtained on admission and at days 1, 2, 3, 5 and 7 after TBI. Its concentration was measured by enzyme-linked immunosorbent assay. RESULTS Twenty-six patients (27.7%) died from TBI within 1 month. After TBI, plasma resistin level in patients increased during the 6-hour period immediately after TBI, peaked within 24 hours, plateaued at day 2, decreased gradually thereafter and was substantially higher than that in healthy controls during the 7-day period. A forward stepwise logistic regression selected plasma resistin level (odds ratio, 1.107; 95% confidence interval, 1.014-1.208; P = 0.023) as an independent predictor for 1-month mortality of patients. A multivariate linear regression showed that plasma resistin level was negatively associated with Glasgow Coma Scale score (t = -6.567, P < 0.001). A receiver operating characteristic curve identified plasma resistin cutoff level (30.8 ng/mL) that predicted 1-month mortality with the optimal sensitivity (84.6%) and specificity (75.0%) values (area under curve, 0.854; 95% confidence interval, 0.766-0.918; P < 0.001). CONCLUSIONS Increased plasma resistin level is found and associated with Glasgow Coma Scale score and mortality after TBI.
