The mechanism probably is that Pishang can inhibit the growth, movement and adheresion to extracellular matrix and endothelial cell of liver tumor cells, up-regulate the expression of nm23, down-regulate the expression of CD44, MMP-2, and inhibit the tumor neovascular by supressing the vascular endothelial cell, down-regulating the expression of VEGF, damaging the primitive mesenchymal cells and inhibiting neovascular gemmation.

砒霜具有明显的抗肝癌细胞作用，并有一定的抗侵袭与转移作用，其机制可能与其能抑制肝癌细胞增殖、迁移、阻止肝癌细胞与细胞外基质和内皮细胞粘附、上调肿瘤转移抑制基因nm23表达、下调肿瘤侵袭分子CD44、MMP-2表达以及通过抑制内皮细胞增殖、下调VEGF表达、损伤间充质细胞、阻止新生血管芽生等途径从而抑制肿瘤新生血管形成有关。

Conventional forest breeding is constrained by its long reproductive cycle, which includes long juvenile period, and by its complex reproductive characteristics, such as self-incompatibility and a high degree of heterozygosis. Gene transformation has played an important role in woody plant improvement, which can shorten breeding period and breed varieties with high salt tolerance.

随着分子生物学技术的发展，从盐生植物中分离出抗盐基因，导入林木，获得抗盐品种；况且林木由于其较长的幼年期，常规育种有明显的局限性，而通过转基因可以在较短时间内获得高抗盐品种，缩短育种周期，因此开展林木抗盐育种具有重要的意义。

The ability of cold resistance of almond was analyzed by the formulation of LT50, the investigation of over-wintering, the measurement of water content in dormant period and the analysis of anatomical structure in the annual branches of two introduced varieties. The results showed: the LT50 of Fritz, Nonpareil and CK was -24.88℃,-20.56℃ and -17.15℃, respectively; the index of chilling injury of these varieties was 10%, 45% and 87%, respectively; and the classification of cold resistance was in turn high resisting, moderate resisting and easily shoot-shriveling.

通过对两个引种扁桃扶兹和那普瑞尔1年生枝条的半致死温度(KT50)拟合、越冬调查、休眠期的含水率及其解刨结构的分析，对扁桃的抗寒力进行了研究，结果表明：Fritz、Nonpareil及CK1年生休眠枝的半致死温度(LT50)分别为-24.88℃、-20.56℃和-17.15℃；冻害指数分别为10%、45%和87%，抗冻害评级依次为高抗、中抗、易抽。

Oxford cup in vitro antibacterial medicine cup showed that it had vitro inhibitory action on beta streptococcus and colibacillus with crude drug content of 0.5g/ml; it had vitro inhibitory action on staphylococcus aureus,pneumococcus, beta streptococcus and colibacillus with crude drug content of 1.0g/ml,and decreased the death rate of mice caused by staphylococcus aureus.

牛津杯法体外抗菌试验表明0.5g生药量/ml时对乙型链球菌、大肠杆菌有体外抑制作用，1.0g生药量/ml时对金黄色葡萄球菌，肺炎球菌，乙型链球菌，大肠杆菌有体外抑制作用，降低金黄色葡萄球菌引起的小鼠病死率

Latest research indicates that,if eating a great deal of undone eggs for a long time,antibiotin protein in undone egg white can integrate with biotin internal the body as a sort of steady compound,making biotin can't be absorbed by intestinal wall and leading to energy ennui,muscle ache,hair falling off,skin inflamation,appetite letdown,weight droping and so on.When eggs pass through the intestinal tract,it's easy to zymolysis and transformation,sometimes it may appear nitroso compound,which has the function of causing cancer.

最新研究表明，若长期大量吃生鸡蛋，生鸡蛋清内的抗生物素蛋白与体内生物素结合成一种稳定的化合物，使生物素不能被肠壁吸收，则可导致精神倦怠、肌肉酸痛、毛发脱落、皮肤发炎、食欲减退、体重下降等；生鸡蛋经过肠道时，容易发酵变质，有时可能产生亚硝基化合物。

After born, blood groups, Coomb's test, free antibody and antibody release test were done for those 286 babies who were in high risk of HDN, so that we could understand the relationship between the antibody IgG level of pregnant women and ABO-HDN....

结果：2741例O型孕妇中，IgG抗-A效价4、64、128、256和≥512各组分别占61.9%、17.0%、12.6%、6.1%和2.4%。286例母婴血型不合且有ABO-HDN危险的孕妇所生新生儿中共有71例HDN阳性，占24.8%；孕妇IgG抗-A效价为64、128、256和≥512各组HDN阳性率分别为10.7%、28.3%、44.9%和64.3%(P.01)。

There are some toxic substances and antinutritional factors in flaxseed,such as anti-vitamin B6 factors and cyanogenetic glycoside,Which limit the application of flaxseed.

亚麻籽中毒性物质和抗营养因子(如抗维生素B6因子、生氰糖苷等)的存在，尤其是生氰糖苷的毒性限制了亚麻籽的使用。

To apply to circulating cooling water treatment more effectively, a column apparatus was devised by biocidal PVA balls, and some parameters of the column apparatus were researched such as length of filled column, treating time of water and outflux, etc.

结果表明：抗菌PVA小球具有良好的杀菌性能，在杀生剂添加量为m：m=3：2时，杀菌率达到（92 2）％；扫描电子显微镜显示，包埋了杀生剂的抗菌PVA凝胶小球是一种多孔性的球形颗粒，结构较密实，并且包埋效果理想。

Objective To establish a HPLC method for the determination of aceclofenac in human plasma.Methods Acidified samples of plasma (500μL) were extracted with 4 mL of ethyl acetate. The organic phase was evaporated to dryness by nitrogen at 40℃ water bath. The residue was redissolved in mobile phase and then was determined.

醋氯芬酸是一种具有镇痛作用的非甾体类抗炎药物[1]，化学名为[邻-(2，6-二氯苯基)氨基]苯乙酰乙酸，l992年首先于西班牙上市，具有明显广泛的抗炎作用和强力的解热镇痛作用，其生物半衰期较双氯芬酸长，胃肠耐受性较双氯芬酸好，抗炎活性优于萘普生和保泰松[2]。

The results showed that BS-LX04 had strong antagonistic activity on the mycelia growth and conidia germination. The hyphae were suppressed by BS-LX04 and presented malformation. The conidia germination was inhibited, with an inhibition percentage of 73.22% when examined at 24 h after test. The germination was delayed by BS-LX04 and the germ tube and hyphae also presented malformation though some of the spores germinated and formed hypha.
