          ABSTRACT    OBJECTIVE  To  investigate  the  ameliorative  effects  and  potential  mechanism  of  total  secondary  ginsenosides
         (TSG)  on  hypertrophic  changes  of  primary  cardiomyocytes  stimulated  by  angiotensin  Ⅱ (Ang Ⅱ ).  METHODS  Primary
          cardiomyocytes  were  isolated  from  the  hearts  of  neonatal  SD  rats  and  divided  into  the  following  groups:  control  group,  AngⅡ
          group (2 µmol/L), TSG group (7.5 µg/mL), PFK-015 group [6-phosphofructo-2-kinase/fructose-2, 6-bisphosphatase 3 (PFKFB3)
          inhibitor,  10  nmol/L],  and  TSG+PFK-015  group (TSG  7.5  µg/mL+PFK-015  10  nmol/L).  The  surface  area,  protein  synthesis,
          energy  metabolism-related  indicators  [free  fatty  acid (FFA),  coenzyme  A (CoA),  acetyl  coenzyme  A (acetyl-CoA)],  and  the
          expressions  of  glycolysis-related  factors  [hypoxia-inducible  factor  1α (HIF-1α),  glucose  transporter  protein  4 (GLUT-4),  lactate
          dehydrogenase A (LDHA), pyruvate dehydrogenase kinase 1 (PDK1) and PFKFB3] in primary cardiomyocytes of each group were
          measured.  RESULTS  Compared  with  the  control  group,  the  surface  area  of  primary  cardiomyocytes  and  protein  synthesis  were
          significantly  increased,  the  content  of  FFA,  protein  and  mRNA  expressions  of  HIF-1α,  LDHA,  PDK1  and  PFKFB3  were
          significantly  increased  or  up-regulated  in  the  AngⅡ  group,  while  the  contents  of  CoA  and  acetyl-CoA,  the  protein  and  mRNA
          expressions  of  GLUT-4  were  significantly  decreased  or  down-regulated (P<0.05).  Compared  with  the  AngⅡ  group,  both  TSG
          group  and  PFK-015  group  showed  significant  improvements  in  these  indexes,  with  the  TSG+PFK-015  group  generally
          demonstrating superior effects compared to either treatment alone (P<0.05). CONCLUSIONS TSG can reduce the surface area of
          AngⅡ-induced  primary  cardiomyocytes,  decrease  protein  synthesis,  and  inhibit  their  hypertrophic  changes.  These  effects  may  be
          related to improving energy metabolism and the inhibition of glycolysis activity.
