    1.8 Analysis of mitochondria function by relative cell viability among I /R model groups and 3MA-treated groups第11-12页
    1.9 Statistical Analysis第12页
2 Results第12-22页
    2.1 Autophagy was gradually activated within N2a cells as oxygen-glucose- serum deprivation went on, and highly elevated especially after reperfusion.第12-13页
    2.2 Autophagsome was found more in cortex and hippocampus of MCAO side of brain tissue after reperfusion than the untreated side第13-17页
    2.3 Cytosolic Beclin-1 shared the same change pattern with LC-311 in IR model groups,and class Ⅲ P13K/beclin-1 was indispensable for activation of autopahagy in the process of reperfusion.第17页
    2.4 Reperfusion induced delayed inactivation of mTORC1, while Rapamycin treatment weakened the autophagy activation during the process of reperfusion.第17-18页
    2.5 Analysis of mitochondria function by relative cell viability among I /R model groups and 3MA-treated groups第18-22页
