Abstract:
Objective To make clear glial acidic protein and excitatory amino acid levels in the early expression of neonatal brain injury and the mechanism of brain injury,and the value of early diagnosis and prediction of serum glial fiber acidic protein and excitatory amino acid in neonatal cerebral palsy.Methods This study chose high-risk infants with cerebral palsy as the research object,the concentration of excitatory amino acid and enzyme linked immunosorbent assay were detected by reverse phase high performance liquid chromatography,followed up for 12 months,the occurrence of cerebral palsy was analyzed statistically.Results Compared with the normal group of glial fibrillary acidic protein,glutamic acid and aspartic acid levels,three indexes of children with cerebral palsy were higher than normal group(glial fibrillary acidic protein:(119.46±43.68),(119.46±43.68),(62.57±35.31),(134.02±32.79) ng/L;glutamic acid:(7.52±3.94),(6.49±2.88),(8.15 ±2.03),(1.72±0.59) μmol/L;aspartic acid:(3.81±1.09),(4.23±1.91),(3.67±2.14),(1.35±0.71) μmol/L;F=4.117,4.117,4.117;P<0.05).Glial fibrillary acidic protein,glutamic acid and aspartic acid levels in the high-risk group,the perinatal high-risk group and the pre birth high-risk group had no significant difference (P>0.05).The levels of serum glial fiber acidic protein,glutamic acid and aspartate in children with cerebral palsy were higher than those in the normal group,comparison between spastic group,athetotic group and mixed group(F=5.032,6.004,3.792),there was no significant difference in the levels of glial acidic protein,glutamic acid and aspartate(P>0.05).Conclusion The concentration of excitatory amino acids and acidic protein in the serum of the patients with high risk of cerebral palsy has some value,the concentration of serum excitatory amino acid and the concentration of glial fiber acidic protein are correlated with the degree of brain injury and the time in children with cerebral palsy.
