title: [Effect of serum containing tengcha total flavonoid and dihydromyricetin on proliferation and apoptosis of HepG2 cells].
abstract: OBJECTIVE
  To observe the effect of serum containing Tengcha total flavonoid and dihydromyricetin on proliferation and apoptosis of HepG2 cells.
  
  
  METHODS
  Serum containing respectively Tengcha total flavonid, dihydromyricetins and CTX and control serum were prepared by serological pharmacology method. MTT assay was used to observe the proliferation inhibition rate of HepG2 cells after incubated with different kinds of serum. Inverted microscope was utilized to observe the morphological changes after HepG2 cells were treated with different serum. AnnexinV/7AAD double label method was used to detect earlier period apoptosis cells.
  
  
  RESULTS
  Both serum containing 20% Tengcha total flavonid and serum containing 20% dihydromyricetin could restrain the HepG2 cells proliferation at different levels and the morpholological changes of apoptosis were observed. AnnexinV/7AAD double label method showed that the earlier period apoptosis cells rates were increased by serum containing 20% Tengcha total flavonoid, but serum containing 20% dihydromyricetin did not show influence on the earlier period apoptosis cells.
  
  
  CONCLUSIONS
  Tengcha total flavonoid can restrain the HepG2 cells proliferation and induce earlier period apoptosis cells.
