RESUMEN
Objective To explore the protective mechanism of fructose-1, 6-disphophate on the hypoxic-ischemic brain damage of neonatal rats.Methods Seven-day-old Wistar rats were randomly divided into HIBD control group,saline-treated group, FDP-treated group. FDP-treated group was redivided into groups of high, middle and low dose.The expression of caspase-3mRNA was detected at 24h after HIBD with RT-PCR. Results There were no sifnificant differences of the caspase-3 mRNA expression among the saline-treated group, HIBD group and low dose FDP-treated group(P >0.05).The expressions of caspase-3 mRNA in the middle and high dose FDP-treated groups decreased significantly as campared to the above three groups (P < 0.05), but there was no significant difference between the two groups (P > 0.05). Conclusion The neuronal protective mechanism of FDP might be related to dewnregulate the gene expression of caspase-3 in brain tissue,and decrease the apoptosis of neuron after HIBD.
RESUMEN
Objective To observe changes of serum concentrations of interleukin-18(IL-18) and intercellular adhesion molecule-1(ICAM-1) in neonates with hypoxic-ischemic encephalopathy(HIE) and to explore the correlation of the 2 indices and its effect on patients′condition.Methods Thirty newborn infants met the criteria for HIE.There were 16 cases in mild HIE group,14 cases in moderate and severe HIE group.Twenty normal newborn infants were used as control group.The serum concentrations of IL-18 and ICAM-1 of HIE group and control group were detected using ELISA on the third day and 7th day.Results 1.The IL-18 levels of the mild,moderate and severe HIE and control groups measured within 3 days of life were (120.1?12.7),(175.1?15.4),(100.3?12.5) ng/L,respectively.The concentrations of IL-18 in HIE groups were higher than that of control group(Pa
