Traumatic brain injury (TBI) is the most common type of nerve injury and it severely endangers the public health. It is necessary to accurately measure the early neurological function of brain injury for monitoring its prognosis and therapeutic interventions. Glasgow Coma Score (GCS) and Computed Tomography (CT) are often used to diagnose the severity of TBI. However, GCS has its drawbacks in the observation of prognosis, because it is interfered by analgesics, sedatives and relaxants in the evaluation of neurological function. CT may miss the diagnosis of diffuse axonal injury (DAI) and the monitoring of intracranial pressure (ICP). Secondary injuries after TBI, such as oxidative stress, inflammatory damage, and abnormal metabolism, can destroy cerebral blood vessels and structures, which also affect the diagnosis of injury. Therefore, there is an urgent need for new methods to quickly identify which patients are likely to suffer brain injury or even cause persistent disability. Detection of brain injury biomarkers based on blood and brain tissue has long been used to assess the severity of TBI, but no biomarkers have been found for early diagnosis of mTBI and prognosis of different degrees of brain injury. Protein and metabolic product differences were detected from blood or the lesion samples of normal population, patients with traumatic brain injury and/or non-brain injury using mass spectrometry proteomics and metabolomics analysis platform, and diagnostic markers of potential traumatic brain injury were found, and their differential and diagnostic values were discussed.
- Study Type: Observational
- Study Design
- Time Perspective: Prospective
- Study Primary Completion Date: December 31, 2022
- Diagnostic Test: diagnostic of specific biomarkers
- Protein and metabolic product differences will be detected from blood or lesion samples of normal population, patients with traumatic brain injury and/or non-brain injury using mass spectrometry proteomics and metabolomics analysis platform. Diagnostic markers of potential traumatic brain injury will be found, and their differential diagnostic values were discussed.
Arms, Groups and Cohorts
- Normal group
- normal population
- Brain injury group
- patients with traumatic brain injury within 24 hours
- Non-brain injury group
- Non-brain injury group refers to patients with limb injury or systemic injury except brain injury.
Clinical Trial Outcome Measures
- Protein levels of GFAP、UCH-L1、H-FABP、Aβ40、Aβ42、IL-10、NF-L、S100B and tau
- Time Frame: One year
- The difference protein levels of GFAP、UCH-L1、H-FABP、Aβ40、Aβ42、IL-10、NF-L、S100B and tau assessed by the proteomics of the one year after traumatic brain injury.
- Discovery of metabolic biomarkers in plasma that will lead to the early detection of traumatic brain injury
- Time Frame: One year
- Metabolic biomarkers in plasma, such as methionine、glycine、cysteine、gamma-glutamylleucine、5-oxoproline、alpha-ketobutyrate、2-hydroxybutyrate, etal.. assessed by the metabolomics of the one year after traumatic brain injury.
