The history of the world's economic growth shows that economic growth tends to show off in some growth points to some extent, and then extend outside, affecting the overall situation of economy. Inner Mongolia has experienced three phases of economic development since reform and opening to the outside, determining natural factor, economic factor and soft environmental factor as growth points, the practice of which proved to be high efficient. However, problems exist as well. To promote Inner Mongolian economic development can hardly adopt a all-round model which advances side by side. Instead we should choose and determine economic developing strategy from Inner Mongolian regional growth points and enterprises growth points, bring the district superiority into full play, forming enterprise groups, and promoting the superior upgrade of economic structure so as to bring along the sustained, stable development of Inner Mongolian economy.

世界经济发展史表明,经济增长往往以不同的程度首先出现在一些增长点或增长极上,然后向外扩散,对经济全局产生影响。改革开放以来,内蒙古经济发展大体经历了以自然因素、经济因素和软环境因素为主确定增长极的三个阶段,实践证明是高效率的,但也存在着很多问题。促进内蒙古经济发展,不可能采取全面铺开、齐头并进的模式,而是要从区域增长极和产业增长极两个方面选择和确定经济开发战略,发挥地区优势,形成产业集群,促进经济结构优化升级,以便带动全区经济持续稳定地向前发展。

OBJECTIVE:Animal cell culture medium is an important factor of cell culture in vitro,which can influence the cell growth.So this article made a systematic summary on the development and application of animal cell culture medium.DATA SOURCES:A computer-based search of related English articles between January 1990 and March 2006 was conducted in PUBMED with the of "cell culture,culture medium,serum-free medium,development".Meanwhile,Wanfang database was searched for relevant Chinese articles between January 1990...

OBJECTIVE:Animal cell culture medium is an important factor of cell culture in vitro,which can influence the cell growth.So this article made a systematic summary on the development and application of animal cell culture medium.DATA SOURCES:A computer-based search of related English articles between January 1990 and March 2006 was conducted in PUBMED with the of "cell culture,culture medium,serum-free medium,development".Meanwhile,Wanfang database was searched for relevant Chinese articles between January 1990 and March 2006 with the key words of "cell culture,culture medium,serum-free medium,development".STUDY SELECTION:There was a first inspect on the data and a review on the quotation of every literature.Inclusion criteria:articles about the development and application of animal cell culture medium.Exclusion criteria:repetitive studies or Meta analysis articles.DATA EXTRATION:A total of 63 related literatures were collected,28 in which were in accordance with the inclusion criteria,and 35 excluded literatures were old in contents or repetitive ones.Of 28 literatures accordance with the inclusion criteria,18 were correlated with the three stages and application of animal cell culture medium,4 were related with the generation-deviation of the serum-free medium,and 6 were on the application of the serum-free medium.DATA SYNTHESIS:Animal cell culture medium was divided into three stages:natural medium,defined medium and serum-free medium.Stage of natural medium was a beginning and original studying stage on animal cell culture medium,it built a consistent foundation for defined medium stage.On the basis of the natural medium stage,defined medium stage made a fast development,it could support cell proliferation through adding certain ingredients.Calf serum was a general added ingredient.Although there were some active materials,which could support cell growth in calf serum,there were also some disadvantages for cell culture.Serum-free medium stage aimed at seeking the substitute of calf serum,which could both satisfy the request of cell culture and avoid a serial of problems caused by calf serum.Serum-free medium was divided into four generations,there were some disadvantages in the first three generations such as narrow application,hard to preserve cell culture medium and easy to be affected by external factors etc.At present,we devoted ourselves to study and research an all-round model cell culture medium,which was serum-free,protein-free,sterilized by high temperature and could fit many different species cell growth.We wish that technique of animal cell culture can be perfected through gradual study of animal cell culture medium,so as to extensively apply it to the preparation of biological product and genetic engineering.CONCLUSION:Serum-free medium has an evident superiority at three stages of animal cell culture medium,which has an extensive application prospect.

目的:动物细胞培养基是体外细胞培养的重要因素,能够影响细胞生长。为此本文就动物细胞培养基的发展及应用作以系统的总结。资料来源:应用计算机检索PUBMED1990-01/2006-03期间的相关文章,检索词为“cellculture,culturemedium,serum-freemedium,development”,并限定文章语言种类为英文。同时计算机检索万方数据库1990-01/2006-03期间的相关文章,检索词为“细胞培养,培养基,无血清培养基,发展”,并限定文章语言种类为中文。资料选择:对资料进行初审,并查看每篇文献后的引文。纳入标准:文章所述内容应与动物细胞培养基的发展及应用研究相关。排除标准:重复研究或Meta分析类文章。资料提炼:共收集到63篇相关文献.其中28篇文献符合纳入标准,排除的35篇文献为内容陈旧或重复。符合纳入标准的28篇文献中,18篇涉及动物细胞培养基发展的3个阶段及其应用,4篇涉及无血清培养基的分代,6篇涉及无血清培养基的应用。资料综合:动物细胞培养基划分为天然培养基、合成培养基和无血清培养基3个阶段:天然培养基阶段是对动物细胞培养基最初的也是最原始的研究阶段,为合成培养基阶段...
