Inquiry Summary for Universities English Teachers' Self-development

College English teachers' Self development apparently affects teaching quality, major curriculum development and inquiry development. The scope of inquiry summary indicates the intrinsic factors as awareness of professional competence, professional-knowledge learning awareness, awareness of teaching means, development awareness and the notions alike. And the summary comes to the findings that foreign ones ignore the effect of the external factors, the domestic just focus on the teaching pattern of team, yet ignore the scientific and inquiry group construction.

中药复方双术油抗肿瘤机制的研究

目的本研究旨在探讨复方双术油(BELY)的体内外抗肿瘤作用机制。方法采用CCK-8试剂盒检测对K562、MDA-MB-231、LOVO和HepG2的影响;建立小鼠S180及H22肿瘤模型,观察BELY对该模型的作用;Elisa法测定IL-2、IL-6、IL-12及TNF-α的水平,探讨BELY对荷瘤小鼠免疫功能的影响;流式细胞仪测定荷瘤小鼠外周血CD4+/CD8+。结果 BELY对HepG2、K562、Lovo、MDA231均有一定的生长抑制作用,并有良好的量效关系。BELY显著抑制S180和H22的生长,提高荷瘤小鼠的胸腺指数、脾指数和体重。BELY可明显升高小鼠血清中IL-2、IL-6、IL-12和TNF-α的水平,外周血CD4+/CD8+明显升高。与生理盐水组比较,P<0.01或P<0.05。结论 BELY既可以抑制肿瘤细胞生长,又可通过增强免疫从而达到双相抗肿瘤的作用。
