Current situation and existed problems on bilingual teaching of molecular biology in medicine in our university were described in brief in present paper.According to actual teaching conditions of our university,and the developmental tendency on bilingual teaching in our state,some suggestions on promoting bilingual teaching of molecular biology in medicine,such as,bilingual teaching materials selection,course arrangement,teaching methods reformation,teachers training etc,were provided.

Objective To investigate the effects of chrysin(ChR) on the induction of differentiation and apoptosis-promoting of HepG 2 human primary hepatocacinoma cells. Methods The HepG 2 cells were cultured in vitro, and then treated with ChR and all-trans retinotic Acid (RA), respectively, the alterations of nucleocytoplasm and tubulin arrangement after Gimsa staining and Coomassie brilliant blue staining were observed. The survival rate and the inhibitory rates of HepG 2 cells were determine by trypan blue counting method and MTT assay. The Alpha-fetoprotein(AFP) secretory amounts of the cells were detected by radioimmunoassay(RIA). The activities of alkaline phosphatase(ALP) andγ-glutamyltranspeptidase(γ-GT) were assayed by enzymatic reaction kit. The synthesis of tyrosine-α-ketoglutaric acid transaminase(TAT) in cells were investigated by Diamondstone spectrophotometry. Results After treatment with ChR or RA at 1.0~100μmol/L for 48 h, the proliferation of HepG 2 cells were inhibited significantly, compared with vehicle group (P<0.05 or P<0.01), the inhibitory potency of both ChR and RA on HepG 2 cells was equivalent and indicated in dose-dependent manner. After treatment with 10μmol/L ChR or RA for 48 h, HepG 2 cells disaggregated and grew to spindle-shape, their nuclei became smaller and the number of nucleolus were fewer. Furthermore, tubulin arrangement of cells tended to be more ordered and the tubulin synthesis increased significantly. At 24~96 hours treated with 10μmol/L ChR, the activities of TAT and ALP in cells were all increased distinctly (P<0.05, P<0.01), and the secretory amounts of AFP and the specific activities ofγ-GT were decreased significantly (P<0.05, P<0.01). Conclusion Chrysin can inhibit the proliferation of HepG 2 cells and induce them to differentiate to mature cells.
