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。

"This is an exciting discovery because it extends the time range for liquid water on Mars, and the places where it might have supported life," said CRISM principal investigator Scott Murchie of the Johns Hopkins Applied Physics Laboratory in Laurel, Md. The identification of opaline silica tells us that water may have existed as recently as 2 billion years ago.

" "这是个令人兴奋的发现，因为该发现延长了水在火星上的存在时间，也扩大了可能支持生命存在的范围，"专用小型侦察影像频谱仪的主要研究人员、马里兰州劳瑞尔市约翰霍普金斯应用物理实验室的斯科特·默基说，"蛋白石硅酸盐的发现使我们可以断定：仅仅20亿年前，火星上仍有水存在。

Marie Curie, a famous scientist, also has set a good example. In 1898, Marie found a new element in the pitchblende. In order to improve her discovery, Marie and her husband worked hard. At last they saw the dim blue light of new element ——radium.

玛丽·居里，一位著名的科学家，也给我们树立了典范。1898年，居里夫人在铀矿里发现了新元素，为了证明她的发现，居里和她的丈夫努力钻研，最后他们终于看见了镭的蓝光，发现了新元素。

Results 1 week af ter injection , the average diameter of tumors ineach test group decreased when compared with the cont rol group. In 100 % acetic acid2group , only 1case had renascent tumors near the necrosis focus.

结果 注射后一周各实验组肿瘤直径均减小，对照组肿瘤直径明显增大。100 %乙酸组10 例仅1 例在坏死灶周围发现新生灶，而50 %乙酸组发现5例，75 %乙酸组发现7 例。

Well, if you very value Avalokitesvara, and if you begin to see, even a little bit, that actually this worldly life has not too much value, like that Sadhu, but actually, I mean not even like that Sadhu, just you know every day maybe just a moment or two thinking that the worldly has not too much essence.
