The mechanism of PPS accelerating IEC-6 cells migration was also researched with gene-chip technique. The Altas Clontech Rat cDNA Chip which consisted of 1176 spots representing different functional categories such as heat shock/stress, cell cycle, transcription factors, hormones, metabolism, etc was used. Result showed in cell migration model of IEC-6 cell line, compared with control group, expression of 38 genes in total 1176 genes varied in cells treated by PPS, including 21 genes up-regulated and 17 genes down-regulated. Date analyze showed the mechanism of PPS accelerating IEC-6 cells migration mainly related with promoting the numbers and activity of cellular ion channel, especially 〓 channel.

从以上实验结果中我们可以得出以下结论：四君子汤总多糖具有促进IEC-6细胞增殖、迁移、粘附的作用；四君子汤总多糖无论是对IEC-6细胞增殖、或者迁移的作用均优于各单味药多糖，可能是各种单味药多糖综合作用的结果；多糖可能是四君子汤"益气健脾"药效的主要成分；小肠上皮细胞可能是四君子汤总多糖的作用靶点之一，提示临床采用四君子汤及"益气健脾"法治疗"脾虚证"的疗效机制可能与增强机体的整体免疫和肠道粘膜免疫功能有关。

This article starts form carding the formation and development of the animations in the United States, Japan and Europe, in their respective national television animation style characteristics. In the second chapter, from the national culture, folk customs and ways, the character and geographical four conditions explore the United States, Japan, Europe, ethnic style animation in the film formation due to the dynamic; Chapter III trays to find the common aesthetic features of the Television Animation factors in United States, Japan, Europe, also this part describes the characters from four aspects, such as to find truthfulness, to find kind and so on. Chapter four is the key of this article, this part colludes several parts , such as film animation level, the way how animation to present to the concept of integrity, the character and language of the text character and so on . This end of this article is a summary of papers, down from globalization understanding of the vision of China Television Animation, the theoretical study of the ultimate goal is to practice creative services, what is more important is a comparative analysis, which received some of reference, identify China Television Animation and the gap between other countries, in order to learn from foreign advanced development of the film and television animation experience in the domestic film and television animation themes and concepts updates, in the localization of the close integration with the international on the road to the former OK, can have a more far-reaching significance.

论文首先从美、日、欧、中影视动画各自民族风格的特点出发，对其民族风格的形成与发展进行系统的梳理；进而在第二章中，从民族文化、民风民俗、民族性格和地域条件四个方面探究美、日、欧、中影视动画民族风格形成的动因；第三章是对美、日、欧、中影视动画的同质性因素进行比较，论文从启真、扬善、弘美、尚趣四个维度来寻求其共通的美学特征；第四章中外影视动画民族风格的异质性因素比较是本文的重点，也是论文的难点，这一章涉及到许多影视动画本体性的层面，拟从动画的观念品格、文本品格和行为品格三个方面进行把握、比较；最后一章是论文的总结，从全球化的视野下来认识中国影视动画，理论研究的最终目的是要为实践创作服务的，因而，论文更主要的是通过比较分析，从中获得一些借鉴性意见，找出中国影视动画和其他国家之间的差距，更好的学习国外影视动画先进的发展经验，以期对国产影视动画在题材和观念的更新上、在本土化与国际化紧密结合的道路上如何前行能够有更为深远的指导意义。

Great progress has been made by taking the following technical improvement for the 2500 ton Hydropress: to replace thin oil with lithium grease in its lubricating system; to add four manual grease pumps; to lubricate the four griding parts of the movable beam and the six parts of the column plug sleeves.
