We also discovered that selenium can decrease hematolysis and effects function of vacuole toxin of HP. morphological conversion from spiralto coccoid forms occurredwhen HP was caltured with selenium and most of coccoid forms had fragmentary flagella and pilus; the effection of selenium to activity of urease, catalase, alkaline phosphatase is not exist or not evidence; selenium enable pET32a-vacA-E. coli BL21 which can express VacA produce yellow lipochrome, and the color become deeper with increasing of concentration of selenium; selenium can decrease expression of recombined VacA by restrain the growth of pET32a-vacA-E. coli, but can not influence activity and gene equence of VacA; selenium can enhance the suppression effect of recombined VacA for gastric cancer cell, depress the index of cell multiplication and the forming rate of colony, decrease the number of cell in S period, increase total of cell in G period; After purified, the recombined VacA can be identified by VacA antibody.

结果：体外实验结果表明：一定浓度的硒作用HP后，HP菌落数量随着硒浓度的增加而减少，菌落颜色由灰白色变为砖红色，溶血现象随硒浓度的增加和作用时间的延长而逐渐消失，HP的形态由弯曲形变为球形或椭圆形，鞭毛及菌毛出现脱落现象；硒对尿素酶、过氧化氢酶、碱性磷酸酶活性无影响或影响不明显；一定浓度的硒能使表达VacA的pET32a-vacA-E.coli BL21工程菌产生脂溶性砖红色色素，颜色随硒浓度增加而加深；一定浓度的硒通过抑制pET32a-vacA-E.coli BL21工程菌的生长，减少重组VacA表达量，但不影响其空泡毒活性及编码基因序列；硒能增强重组VacA对胃癌细胞的抑制作用，使细胞分裂指数和集落形成率降低、S期细胞数量减少，G1期细胞总数增加；纯化后的VacA重组蛋白可被VacA抗体识别，具有良好的抗原性。

For it is absurd and stupid to speak of the one who existed before every age and is coeternal with the Father, needing a second beginning so as to exist.

Results and conclusion: the mathematics mechanism theory of Nervous system about their basic data and interconnection may be expressed by the neural information encoding formulation: x1=m1a/b and y1=n1c/d、x2=m2b/a and y2=n2d/c The neural information encoding formulation have novenary and undecimal and many other scales. All Periphery Nervous- Cerebral Cortex- Sympathetic Nervous have obvious and invisible encoding data in 2 kinds: yin and yang ,2kinds:ambulatory and static state, 3 grades: Max Med and Min. they all exist in obvious or invisible type. Just like a cogwheel system and there is a inter-meory function among the data.

结果与结论：神经系统基本数据及其相互关系的数学机制可用神经信息编码计算公式：x1=m1a/b与y1=n1c/d、x2= m2b/a与y2=n2d/c表达；神经信息编码计算有9与11等多种进位制；周围神经-大脑皮质-交感神经皆以隐性或显性型式存在阴阳两种静动两类大中小三级编组数据，犹如齿轮系统，数据之间起着互记功能；45对周围神经-54对大脑皮质分区-15对交感神经、脊神经前根与后根神经小束数之比3/5等神经系统基本数据皆是由数学计算机制决定形成。
