About

TBI, as a potential risk factor, causes a 1.5 times higher risk of neurodegenerative disease to up to 30-70% of TBI patients with neurological symptoms. Brain trauma is an important global medical, public health and social problem. Early diagnosis and effective treatment can effectively reduce the disability rate of patients and the incidence of neurological sequelae, and has increasingly become the focus of the international scientific research community. Exploring blood-based biomarkers has potential clinical value, which can greatly help clinicians to evaluate patients' conditions and develop reasonable plans, and then improve the clinical management and treatment of patients with craniocerebral trauma. Further research work is needed to be done to identify the most effective and efficient biomarker or combination marker strategies for integration into clinical treatment.

Full description

Over the entire injury time phase of the TBI, the sampling of blood samples in the study was set within 24 hours, aiming to identify a set of biomarkers with assessment significance early after TBI. 1. The aim of this study was to investigate the correlation of different markers concentrations in blood and prognosis in patients with TBI. 2. Identify a set of biomarkers with assessment significance in the early period after TBI.

This project prospectively recruited 80 volunteer patients with voluntary TBI strictly in accordance with the inclusion and exclusion criteria, and 80 control groups matched by gender, age and education. 1 For patients who met the inclusion criteria, cranial MR and CT scans were performed at day 3 and discharge on admission, and clinical neuropsychological scale evaluation and peripheral whole blood collection were performed within 24 hours before each scan. 2. All fracture controls matched for sex, age, education and hands will complete primary MRI and CT examination, clinical neuropsychological scale evaluation and peripheral whole blood collection.Specific study contents include: 1. TBI patients were divided into mild, moderate and severe groups according to GCS scores, Together with the fracture patients in the control group, Blood and cerebrospinal fluid were collected from patients with TBI (mild: two blood collection after admission and discharge; Moderate and severe levels: admission, day 3, discharge, Take blood for three times and take cerebrospinal fluid once at admission); Blood of fracture patients (at admission) 2. Statistical analysis of clinical data. 3. Biomarker concentration determination: blood: NSE, GFAP, S100B, Tau, MBP (myelin basic protein), NFL; CSF: NSE, GFAP, Tau, NFL blood-brain barrier index (cerebrospinal fluid albumin / serum albumin). Among them, there was no dynamic monitoring, and comparison of blood and CSF markers in different groups. 4. Correlation analysis of blood markers, cerebrospinal fluid markers and the degree of brain injury (Spearman correlation analysis) shows the correlation between biomarkers and early assessment of the degree of TBI. 5. Follow-up was 3M / 6M, according to the GOS score: good prognosis and poor prognosis. 6. The correlation of serum and / or cerebrospinal fluid biomarker levels at admission and at discharge with GOS score (ROC curve).
