Abstract:
Objective To observe the expression of CD_(25),CD_(25) mRNA,interleukin-1?(IL-1?) in peripheral blood of newborns with hypoxic-ischemic encephalopathy(HIE) and its clinical significance.Methods The peripheral blood mononuclear cells(PBMC) of newborns with HIE and normal controls were isolated by routine Ficoll-Hypaque,and the level of CD_(25) induced and non-induced by phytohernagglutinin(PHA) were detected by biotin-streptavidin(BSA),CD_(25) mRNA was detected by real-time PCR and IL-1? in serum was detected by enzyme-linked immunosorbent assay on the first,third and seventh day after birth.The final expressive level of CD_(25) mRNA was based on rate of CD_(25) cDNA and gluceraldehyde phosphase dehydrogenase(GAPDH).Results On the first day,the positive rates of CD_(25) induced and non-induced by PHA and IL-1? were(3.6?1.1)%,(20.9?4.8)%,(17.7?8.2) ng/L,respectively.There were significant differences in HIE group and normal controls(P0.05).Conclusions There is obvious inflammatory(rea)ction in babies with HIE.The main character of PBMC of newborns is all infantile and undifferentiated,which surface sign is infantile,and lower level of CD_(25) is expressed.However,the level of CD_(25) mRNA can be expressed consistently during the course of disease.The immunity and immune regulative response in newborns is gradually built up during the growth and can participate in recondition of brain injury caused by HIE.
