摘要
目的:探讨藤茶总黄酮和二氢杨梅素含药血清对人肝癌细胞株HepG2增殖的抑制及凋亡的影响。方法:采用血清药理学方法制备藤茶总黄酮﹑二氢杨梅素﹑环磷酰胺(CTX)含药血清以及对照血清,作用于肝癌HepG2细胞,MTT法检测各种血清对HepG2细胞增殖的影响;倒置相差显微镜观察各种含药血清作用后肝癌HepG2细胞的形态学变化;AnnexinV/7AAD双标记法流式细胞术检测早期细胞凋亡的情况。结果:MTT法和显微镜观察显示藤茶总黄酮和二氢杨梅素20%含药血清能不同程度抑制HepG2细胞增殖,可致细胞形态学改变;AnnexinV/7AAD双标记法检测显示藤茶总黄酮20%含药血清可促肝癌HepG2细胞早期凋亡,但二氢杨梅素20%含药血清对肝癌HepG2细胞早期凋亡没有影响。结论:藤茶总黄酮能抑制肝癌HepG2细胞的增殖,诱导其产生早期凋亡。
Objective ： To observe the effect of serum containing Tengcha total flavonoid and dihydromyricetin on proliferation and apoptosis of HepG2 cells. Method： 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. Result： 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. Conclusion： Tengcha total flavonoid can restrain the HepG2 cells proliferation and induce earlier period apoptosis cells.
