The Stylistic Features of Advertising English——Focus on the Grammatical and Lexical Features

Advertising English as a functional variety has its distinctive linguistic features. This paper will concentrate on grammatical and lexical features from the view of stylistics. In this paper, there are many examples involved, from which we can have a deep understanding of English advertising from the stylistic angle.     

PGC-1α coordinates with Bcl-2 to control the cell cycle in U251 cells through reducing ROS

B-cell lymphoma 2 (Bcl-2) has a dual function, acting as both an oncogene and an anti-tumor gene. It is well known that Bcl-2 exerts its tumor promoting function through the mitochondrial pathway. However, the mechanism by which it suppresses tumor formation is not well understood. We have previously shown that Bcl-2 inhibits cell cycle progression from the G₀/G₁ to the S phase after serum starvation, and that quiescent Bcl-2 expressing cells maintain a significantly lower level of mitochondrial reactive oxygen species (ROS) than control cells. Based on the fact that ROS mediate cell cycle progression and are controlled by peroxisome proliferator-activated receptor-γ co-activator 1α (PGC-1α), a key molecule induced by prolonged starvation and involved in mitochondrial metabolism, we hypothesized that PGC-1α might be related to the cell cycle function of Bcl-2. In this paper, we show that PGC-1α is upregulated by Bcl-2 overexpression and downregulated following Bcl-2 knockdown or downregulation after serum starvation. However, Bcl-2 is negatively regulated by PGC-1α expression. Further, co-immunoprecipitation (co-IP) experiments showed that PGC-1α protein is co-precipitated with Bcl-2 at the G₀/G₁ phase. Taken together, our results suggest that PGC-1α interacts with Bcl-2 after serum depletion, and that Bcl-2 might recruit PGC-1α to reduce ROS, which in turn delays cell cycle progression in coordination with Bcl-2.

引企入校办校进厂产教一体——胶南市职业教育半工半读的探索与实践

以就业为导向、大力推进工学结合半工半读职业教育模式，是新形势下我国职业教育改革和发展的方向。近些年来，许多职业院校积极试行半工半读职业教育，有的已取得了很好的成绩。本刊记者在2002年去青岛时曾采访过胶南电子工业学校，并报导过该校开展半工半读的情况。2006年10月教育部在青岛召开了全国职业教育半工半读试点工作会议，许多单位介绍了开展半工半读的经验。本文作者是胶南市教育局局长。详细地介绍了胶南市开展半工半读的情况，他们的经验可供开展半工半读的院校参考。[编者按]     

一种面向业务领域的web服务发现方法以及支撑框架

针对UDDI关键字匹配带来的服务发现精度低,以及难以从功能相同的多个web服务中选择合适服务的问题,提出一种新的面向业务领域的web服务发现方法和相关框架.当用户请求服务时,根据功能请求从实际服务中抽取出服务簇,然后由业务信息属性等非功能性属性进行协商,确定出适合的服务并与用户请求绑定,而整个发现过程对用户来说都是透明的.通过建立一个基于旅游领域的原型系统IPVita来测试和支持此框架.
