Abstract:
AIM To explore the protective effect of Wenyang Fuyuan Recipe on cerebral ischemia-reperfusion injury (CIRI) in rats.METHODS Among the rats randomly divided into the sham operation group,the model group,the FPS-ZM1 group and Wenyang Fuyuan Recipe group,with 6 rats in each group,all were induced into the rat CIRI models except those of the sham operation group.The rats had the model success verified by TTC staining and modified neurological severity score ( mNSS );their neuronal apoptosis detected by TUNEL staining;their cerebral protein expressions of RAGE and S100 β detected by immunofluorescence staining;their cerebral mRNA expressions of RAGE and p38MAPK detected by RT-qPCR;and their protein expressions of RAGE,AGE,HMGB1,p38 and Bcl-2 in brain tissue detected by Western blot.RESULTS Compared with the sham operation group,the model group showed marked white matter with an enlarged size in the brain tissue ( P<0.05),increased neurological function score ( P<0.05 ),increased number of apoptotic cells in neurons ( P<0.05 ),increased cerebral protein expressions of RAGE and S100β( P<0.05 ),and increased protein and mRNA expressions of cerebral AGE,RAGE,HMGB1 and p38MAPK ( P<0.05).Compared with the model group,the group intervened with either FPS-ZM1 or Wenyang Fuyuan Recipe shared improved conditions in terms of the aforementioned indicators levels ( P<0.05 ),and Wenyang Fuyuan Recipe group showed its particular priority in the efficacy.CONCLUSION Wenyang Fuyuan Recipe may protect the rat brain via AGE-RAGE and its downstream p38MAPK signaling pathway mediated neuronal apoptosis attenuation.
