Objective:To explore the effect and mechanism of ganglioside for hypoxia injury in newborn.Methods:A total of 200 cases of newborn patients in our hospital were analyzed. All the patients were divided into 4 groups, control and ganglioside groups with low, medium and high dose. The neonatal behavioral neurological assessment scores were counted in each group and the serum inflammatory factors and transforming growth factor-β (TGFβ)/Smad parameters were detected.Results:The neonatal behavioral neurological assessment scores were increased after ganglioside treatment and the serum interleukin (IL) 2/10, hypoxia inducible factorαand Smad1, Smad3 as well as TGFβ was decreased dramatically when compared with control group.Conclusions:Ganglioside exerts an effective effect on cerebral hypoxia in newborn mainly by inhibiting the TGFβ/Smad signaling pathway.
