In our study, we found menadione has anticancer potential on human breast adenocarcinoma MDA MB 231 by weather cell cycle arrest, anti proliferation, or apoptosis. Low concentration of menadione (5.8μM) significant inhibited growth curve on breast cancer cells (MDA MB 231) but not breast cells (MCF 10A) by performing MTT and trypan blue cell counting. RT-PCR and western blotting showed menadione increase p21 gene and protein expressions but decrease cyclin E and CDK2 protein expression resulting in cell cycle G0/G1 arrest by flow cytometry.

MTT及生长曲线的实验，发现menadione在低浓度且长时间作用情况下，对在於人类乳腺上皮细胞癌(MDA-MB 231)是有明显的抑制作用，而在正常乳腺细胞(MCF-10A)则没有影响，在分子转录上及蛋白质表现方面也发现低浓度menadione处理24时能使MDA-MB 231诱发p21基因及蛋白表现量增加及cyclin E、CDK2抑制，再经由流式细胞仪分析也发现低浓度 menadione 处理24小时能使MDA-MB 231细胞周期GO/G1比例上升，造成细胞周期停滞，进而抑制细胞生长。

Fibrin oozed from meninges, meninges proliferation and senile cerebral-ventricle narrowness were the direct factors of the development of hydrocephalus.

Methods The cells were divided into 5 treatment groups（10,25,50,75 and 100 μmol·L-1 QUE）, blank control and menstruum control group. The rat C6 cells were cultivated to 1×106·mL-1 in the RPMI 1640 medium, then added into 96 holes board with various doses of QUE by 3 holes per group,and MTT assay was used to observe the proliferation of the cells treated for 24,48 and 72 h. The change of cell cycle was also observed by flow cytometry after the cells were treated with 50 and 100 μmol·L-1 QUE for 48 h. The changes of the protein P53 and Bcl-2 of C6 cells treated with 50 μmol·L-1 QUE for 48 h were detected by immunocytochemical methods.

按QUE浓度分成10、25、50、75及100 μmol·L-15个处理组和空白对照组及溶剂对照组，大鼠脑胶质瘤C6细胞在RPMI 1640培养基中生长达1×106·mL-1后，在96孔板中分别加入上述浓度的QUE继续培养，每组设3复孔，作用24、48及72 h，采用MTT比色法检测QUE对大鼠脑胶质瘤C6细胞的增殖抑制情况，流式细胞术对50及100 μmol·L-1的QUE作用48 h的大鼠脑胶质瘤C6细胞进行周期分析，免疫组化法检测50 μmol·L-1的QUE作用48 h 的p53和bcl-2基因产物。

But 3H-TdR incorporation of HPMC cultured in the medium with high concentration glucose and EGF was increased significantly(P＜0.05)than in the medium with high concentration glucose and VitA. Conclusion EGF and Vit A do not effect the differentiation of HPMC,but can ameliorate the inhibitive effect on proliferation of HPMC by high concentration glucose.It may play an important role in the repair of damaged mesothelium and restoration of its function.
