Progress of major biomarkers for neonatal brain injury in clinical application / 国际儿科学杂志

With the continuous progress of monitoring and treatment skills, the mortality of neonates has gradually decreased, and the long-term neurodevelopmental outcome has become the primary concern of society and families.During the perinatal period, the developing brain is vulnerable to hypoxia, hemorrhage, infection and inflammation, which may cause varying degrees of brain cell damage.Studies have found that proteins released by damaged brain cells can be detected in the body fluid of neonates, which are related to the occurrence and prognosis of neonatal brain injury.This article mainly reviews the recently reported brain injury biomarkers such as S100B, neuron specific enolase(NSE)and glial fibrillary acidic protein(GFAP)in different biological samples and its clinical predictive value for the occurrence of brain injury and neurodevelopmental prognosis.

Research Progress of Biomarkers in Early Diagnosis and Monitoring in Newborn with Brain Injury / 现代生物医学进展

Brain injury is one of the most serious diseases in neonatal period,which can cause cerebral palsy,motor development delay,cognitive dysfunction and learning difficulties and other sequelae,and severely affects the health development and quality of life of the newborn.Neonatal brain injury (NBI) is a wide range of diseases caused by a variety of causes,its clinical manifestations lack specificity,clinically,it is difficult to judge the severity,duration and the time of prenatal injury,and it has been paid much attention to by scientific researchers and clinicians.At present,imaging method is a major means of NBI diagnosis,but imaging examination is usually a lag and limitations.Levels of humoral biomarkers change early after brain injury,and early brain injury can be predicted by detecting their changes.In recent years,a variety of sensitive brain damage biomarkers have been detected in various body fluids of newborns,mainly including neuron-specific enolase (NSE),ubiquitin carboxyl hydrolase L1 (UCH L1),S100B protein,tau protein,myelin basic protein (MBP),glial fibrillary acidic protein (GFAP) and activin A and so on.the application and research progress of these commonly used biomarkers in NBI are reviewed in this paper.
