ABSTRACT
Objective:To investigate the effect of anastrozole on sex hormone levels and michigan cancer foundation-7 ( MCF-7 ) cell inhibition in postmenopausal women with breast cancer. Methods: Totally 80 women with breast cancer were selected. Among them, 40 cases of patients received the routine management and tamoxifen treatment were included into the control group, and another 40 cases of patients received the routine management and anastrozole treatment were included into the observation group. The changes of sex hormone levels, effects and adverse drug reactions of two groups were compared between basetine and three months after treat-ment, meanwhile, the incidence of MCF-7 cell inhibition between two groups. Results:After treatment, the levels of estradiol( ER) , progesterone(PR) and luteotropic hormone(LH) were lower than baselime, however, the level of testosterone was contrary(P <0. 05). Meanwhile, the level of ER, PR and LH in control group were lower than baselime however, the level of testosterone was cont-ray (P<0. 05). The incidence of MCF-7 cell inhibillion between two grugs at time 72 h were higher than the 48 h, the incedence of MCF-7 cell inhibition in observation group were significantly higher than control groups at time 48 h and 72 h (P<0. 05). The rate of total effective in control group(45. 0%) was lower than the observation group(70. 0%)(P>0. 05). There was no significant differente in the micidence of adverse reactions. Conclusion:Anastrozole used for postmenopausal women with breast cancer has significant effi-cacy, high safety and promising inhibitory effect on MCF-7 cell. It can effectively adjust sex hormone level, reduce occurrence and transfer risks of breast cancer.

ABSTRACT
ObjectiveTo investigate the anti tumor effect of Giant Typhonium Rhizome.Methods SH-SY5Y was treated for 24 or 48 h by Giant Typhonium Rhizome.Cell Counting Kit-8 (CCK-8) cell proliferation and cytotoxicity assays were applied to detect the inhibition of SH-SY5Y cells treated with aqueous extract of white monkshood root.AV/PI double staining flow cytometry was applied to explore the mechanism of growth inhibition.ResultsSH-SY5Y cells could be inhibited by root aqueous extract of Giant Typhonium Rhizome,the IC50 at 48 h (50％ inhibitory concentration) was 0.862 mg/ml,while the IC50 at 24 h was 1.158 mg/ml.Western-blot results showed that root aqueous extract of Giant Typhonium Rhizome could induce apoptosis to inhibit tumor cells.ConclusionThe Rhizoma typhonii inhibit the growth of SH-SY5Y.
ABSTRACT
Aim To investigate the effect of MTX(included(±)MTX,(+)MTX and(-)MTX)on the proliferation of ECV304 cells and to explore its mechanisms.Methods ECV304 cells were cultured.The cell proliferation was determined by MTT.The morphological changes were inspected by inverted microscope.Cell cycle phases were assayed by propidium iodide staining flow cytometry.Results ECV304 cells were treated with(+)MTX,(-)MTX and(±)MTX at 1～150 μmol·L~(-1) for 24,48,72 h.The results showed that the proliferation of ECV304 cells was significantly inhibited under different conditions.The order of the inhibited efficacy was(+)MTX>(±)MTX>(-)MTX.The morphology of ECV304 cells were changed by(+)MTX,(-)MTX and(±)MTX treatment,which included the cell shrinkage,chromatin condensation.After administration of 10 μmol·L~(-1) of(+)MTX,(-)MTX and(±)MTX for 48 h,the cell cycle phases were assayed by propidium iodide staining flow cytometry.The result showed DNA replication was interfered by(+)MTX,(-)MTX and(±)MTX treatment.Conclusions The proliferation of ECV304 cells has the chiral selective effects by(+)MTX and(-)MTX treatment,and the inhibition on ECV304 cells proliferation of(+)MTX is significantly stronger than that of (-)MTX.
