Serum S-100B concentration of umbilical cord blood in the early diagnosis of newborn hypoxic ischemic encephalopathy / 中国综合临床

ABSTRACT

Objective To investigate the role of serum S-100B of umbilical cord blood in the early diagnosis of newborn hypoxic ischemic encephalopathy(HIE).Methotis 307 full-term newborns with asphyxia were selected as subiects and 43 normal full-term newborns delivered during the corresponding period were selected as controls.The umbilical cord blood sample was acquired.46 cases of 307 subjects with asphyxia developed into HIE,31 cases with mild HIE and 15 cases with moderate and severe HIE.The serum S-100B concentration of umbilical cord blood was detected by ELISA analysis.Results ①There was no significant difference in the serum S-100B concentration of umbilical cord blood between the male sub-group and female sub-group in normal group;②The concentration in control group and HIE group were(1.03±0.32)μg/L and(2.53±1.1)μg/L respectively(t=8.848,P＜0.05＝;③The concentration in mild HIE group and moderate to severe HIE group were(1.03±0.32)μg/L nd(3.49±1.23)μg/L respectively,which were significantly different with control group(F=79.6909,P＜0.01).Conclusion Sex has no significant relation to the serum S100B concentration.Serum S-100B concentration of umbilical cord blood can be biomarkers for early diagnosis of newborn HIE.
