Because different cell lines may show various levels of susceptibility to adenovirus infection and virus production, non-selectively replicating wtAd5 was used to be a comparison with the tested conditionally replicating adenovirus CNHK500.ONYX-015, the first replication-competent adenovirus entered into clinical trials was also used to be a comparison. We used virus proliferation assay, cell viability assay and western blot to evaluate the proliferation and cytolysis selectivity of CNHK500. Results demonstrated that the CNHK500 virus proliferation multiples in breast cancer cell lines after 48 hours is similar to that of wtAd5, ONYX-015 virus proliferation ability is less than that of CNHK500 in cancer cells.

This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer). At the same time, the effects of different host plants on the development of Tetranychus viennensis were determined by means of the leaf-dish rearing method , in addition, the contents of some chemicals in the leaves of different plants were also determined.

It is suggested that quite a lot of the Be, Co, Cu and Pb could be originated from the syngenetic stage during which the coal-forming plants grew. The strongly seawater-effected peat bog with the reductive and alkaline water could be in favor of the relative enrichment of the Be, Co and Cu, and the faintly seawater-effected bog with the slightly reductive and alkaline water could be in much favor of the enrichment of the Mn, Mo, Ni, P, Pb, Th, Tl and U.

认为凯里煤中相当一部分Be、Co、Cu和Pb起源于成煤植物生长期间的同生阶段；受海水影响强烈的还原偏碱性沼泽环境有利于Be、Co和Cu的相对富集，受海水影响微弱的弱还原性和弱碱性环境条件更有利于Mn、Mo、Ni、P、Pb、Th、Tl和U的富集。

The effects of temperature on the mycelial growth of Rhizoctonia solani AG-l-IA and on its infection in maize were also studied.

本文从四个方面进行了研究：(1)研究了苯丙氨酸解氨酶生理病理变化及其与抗病性的关系；(2)在人工控温条件下，研究温度对玉米纹枯病菌菌丝生长、菌核萌发和侵染的影响；(3)建立人工病圃，系统监测玉米纹枯病的田间发生动态；(4)采用人工接种方法对一批玉米材料进行抗纹枯病的鉴定和评价，继续寻找新的抗源和抗性评价指标。

To investigate the pitting and metastable pitting rules of type 304 stainless steel, potentiodynamic polarization method was employed to study the behavior of metastable pitting and stable pitting on 304 stainless steel in sodium bromide solution and borate/phosphate buffered bromide solutions. The influence of the concentration of Br-、the pH value、the buffer capacity and general environmental factor to pitting potential and metastable pitting was studied as well.

为了更深入地了解304不锈钢的稳态及亚稳态孔蚀规律，本文采用动电位慢扫描法测得了304不锈钢的阳极极化曲线，研究了不锈钢在纯溴化钠溶液及含溴化钠的硼酸盐或磷酸盐缓冲溶液中的亚稳态孔蚀以及稳态孔蚀行为，分析了溴离子浓度、pH值、缓蚀性阴离子、以及缓冲容量和综合环境因子对孔蚀电位以及亚稳态孔蚀特征参数中的形核数目、峰值电流、生长寿命的影响。

Carotene and bixin inhibited the of MCF-7 human breast cancer cell significantly. The effects of carotenoids were pleiotropic.β-Carotene can activate PPARγ signal pathway and regulate expression of the downstream and relative genes, and impel cytochrome C liberation from mitochndria and increase the level of reactive oxygen species in cell.
