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。

The life cycle and pathogenicity of E.stigmosa were observed chronologically. There might be only one merogony stage in the life cycle of E.stigmosa. Each meront contained 3-5 merozoites.

According to the algorithm, TSP cycle was divided into bicycles randomly, and then the best combination was used to compose a monocycle. In this way, the cycle will converges to optimal solution. The proposed algorithm has been evaluated by simulation experiment using public TSPLIB data.

将TSP环路动态随机分解成双环，再用最佳组合方式组合成单环，实现了在总体路径寻优下的局部路径优化，从而使所得路径尽可能接近最优解。

The formation process of the rocks is divided for thefirst time into three cycles corresponding to J2, J3, and K1, respectively, and each cycle into early,middle, and late periods based on intruding contact relationship among different types ofgranitoids.3. A detailed study on the petrological characteristics of different cycles of theMesozoic granitoids supports classification of the rocks into three lithological associationsincluding A-type, high-K calc-alkaline, and calc-alkaline granitoids, of which the first associationbelongs to alkaline series, and the others belong to calc-alkaline series. It is shown that thelithologies change from diorite, quartz monzonite, and granodiorite to monzonitic graniteand syenogranite with periods from early to late in each cycle.4. A preliminary summarization hasbeen made on the evolution characteristics of the rocks.

首次将中生代花岗岩类划分为J2旋回、J3旋回、K1旋回等三个旋回，并依据不同岩石类型间的侵入接触关系，将每个旋回又划分为早、中、晚三期。3、在详细研究区内中生代不同时期花岗岩类岩石特征的基础上，首次将区内中生代花岗岩类划分为碱性系列碱质A型花岗岩类以及钙碱性系列高钾钙碱性花岗岩类和钙碱性花岗岩类等二个系列三种岩石组合类型，确定每个旋回从早期到晚期，岩石均具有从闪长岩、花岗闪长岩、石英二长岩-二长花岗岩-正长花岗岩演化的趋势。4、初步总结了区内中生代花岗岩类的演化特征。
