摘要：The process of division, growth and death for tumour cell mass in the early is simulated. An integrated GUI is provided for users to set the value of each parameters, which are cell growth rates, cell mass division rates, cell mass death rates, simulate type, maximum running time, polarity and cell colour. It can display the growth process of each cell on result GUI. Also, it can display the values of each parameters for observing and analysing in current life cycle on result GUI, which are cell mass division times, cell mass death rate, cell mass division rate and cell mass growth rate. In the process of simulation, The cell growth rate is described by the approach to combine the exponential model with the linear model. In addition, a linked list data structure to store the tumour cells is used by the cellular automata for a reference to determine the position of each cell. It sets up two linked list to store the cells, one of them save the new small division cells and the other one save the big cell. That can make the painting process of cells on result GUI clearer and more organized. At last, the polarity oftumour growth is described for determining the growth direction of cells.

摘要：[Objective] This study was conducted to analyze the difference in the general combining ability of yield traits of rice varieties in china and South Asia and to provide reference for the introduction and utilization of rice restorer lines from South Asia. [Method] A total of 111 hybrids were obtained by crossing 37 restorer lines in china and South Asia with Gang 46A, Lu 98A and Dexiang 074 following a NC II design. The combining ability of eight yield traits of the hybrids was analyzed in Luzhou and Deyang bases of Sichuan Province. [Result] In both bases, the eight yield traits had significant or extremely significant differences between the combina- tions, restorer lines, sterile lines or sterile line^restorer line, suggesting that there were d^erences in the genetic effects between the combinations or lines. The gen- eral combining ability （GCA） variances were all higher than special combining ability （SCA） variances in parents, which indicated that these traits were affected by gene additive effect. Restorer lines contributed more to F1 generation than male sterile liens in the eight yield traits. Nine restorer lines from India and Bangladesh were ranked in the top 15 lines with high GCA in the number of productive tillers in both bases. [***] There was significant differences in the combining ability in the eight yield traits between the restorer lines from china and South Asia. The lines from India and Bangladesh were better than those from china in the GCA of the number of productive tillers, and the lines from china were better than those from India and Bangladesh in the GCA of other traits.

摘要：This paper proposes a new cell intuition simulation method which is a combination of intuitive simulation calculation method and the operation of binary image, and applied it in the innovation of the graphic design process. First of all, we study how to express a variety of graphics, and establish the definition of cell intuitive model, work out the cell intuitive operation process and many new cellular operators such as a variety of matrix blocks crossover operator, a variety of matrix blocks mutation operator, matrix blocks replace operator, matrix blocks compression operator, matrix blocks extension operator. By choosing two or more cells and selecting the artificial selection or fitness selection, we can set up and visualize the design and pick the best design results .Finally, validation is made on this algorithm by an example, and a innovation graphic is also represented.

摘要：背景：间充质干细胞可以在体内或体外分化成肝样细胞,但是间充质干细胞数量少,在1×10^4-1×10^5 个骨髓有核细胞中仅有一个,肝细胞移植和生物人工肝的治疗都需要1×10^10 级的细胞数,利用常规的单层培养方法难以实现。目的：建立一种体外分离、大量扩增培养成人骨髓间充质干细胞的方法。设计、时间及地点：随机对照实验。实验于2005-09/2006-04 在上海市消化外科研究所（上海市教委重点实验室）及上海交通大学医学院附属瑞金医院普外科和器官移植中心完成。材料：骨髓标本收集于上海交通大学医学院附属瑞金医院血液科骨髓检查正常者,供者均为知情同意志愿者。方法：采用 Percoll 梯度离心结合贴壁法分离人骨髓间充质干细胞。应用微载体cytodex3 培养人骨髓间充质干细胞,以普通单层聚苯乙烯（TCPS）培养作对照,用流式细胞仪（FCM）和 MTT 法对其细胞表型和增殖活性进行检测。主要观察指标：①hMSCs 的分离及培养。②hMSCs 的形态学观察。③hMSCs 在cytodex 3 表面生长时的增殖活性测定。④hMSCs 在 cytodex 3 表面生长时 FCM 细胞周期测定。结果：①流式细胞仪检测表明,微载体cytodex3 表面生长的人骨髓间充质干细胞表面标记与普通单层聚苯乙烯培养时一致,表达 CD29、CD44 和 CD105,而不表达CD14、CD34、CD45、VLA-1 和 HLA-DR。②MTT 检测显示,人骨髓间充质干细胞第1-3 天处于适应期,3 d 后进入对数生长期,人骨髓间充质干细胞此期间在 TCPS 和cytodex3 表面的增殖活性无差异 （P 〉 0.05）,而在普通单层聚苯乙烯表面培养时,人骨髓间充质干细胞 6 d 后进入衰退期,而cytodex3 表面生长第 9 天时仍然处于对数生长,差异显著（P 〈 0.05）。③流式细胞仪分析表明,人骨髓间充质干细胞在 TCPS 和cytodex3 表面培养细胞周期分布相同,差异不显著（P 〉 0.05）。结论：微载体 cytodex3 培养技术可以很好地大量扩增人骨髓间充质干细胞,并能保持其良好的增殖活性。
