AIM: To elucidate the effect of ginsenoside Rb1( Gs-Rb1) on the glucose metabolism to improve the viability of the cardiomyocytes under hypoxia,and whether hypoxia-inducible factor 1α( HIF-1α) and / or AMPKα are involved in the process. METHODS: The neonatal rat cardiomyocytes were cultured,and randomly divided into control group,hypoxia( 1% O2,94% N2 and 5% CO2) group,Gs-Rb1( 200 μmol/L) group,Ara-A( 500 μmol/L) group,GsRb1 + Ara-A group,YC-1( 5 μmol / L) group,Gs-Rb1 + YC-1 group,Ara-A + YC-1 group and Gs...
