1.2.2三维重建观察螺钉最佳进钉点的位置和各方向螺钉进钉点关系，调整CT值下限阈值使椎弓后部结构尽量显示清晰，以利观察。 1.3统计方法本实验采用SPSS13.0统计软件。对同一椎体左右两侧椎弓根螺钉相对数据行计量资料配对样本t检验，对男女组间相关数据行计量资料独立样本t检验，对男女组内不同腰椎节段间相关数据行单向方差分析及不同腰椎节段间LSD法多重比较。

Because the dimeric form is the active form to exert its biological activities, many trials failed to express TGF β s in prokaryotic systems because of their complex folding manner and disulfide patterns. In 1991 Cerletti and coworkers from Ciba-Geigy Corporation in Switzerland successfully finished the functional expression of human TGF β 2 in bacteria, but the details are protected by the patent.

由于双体是其发挥生物活性的形式，TGF β复杂的折叠方式和二硫键配对使其早期原核基因工程研究都以失败而告终。1991年，瑞士Ciba-Geigy公司的Cerletti等成功完成了人TGFβ2基因的细菌表达，但其技术细节被专利加以保护。

Antisense technologies inhibit the expression of a target gene in a sequence-specific manner, with DNA or RNA molecules binding complementally to the target mRNA via Watson-Crick base pairing. As a result, the target mRNA is either degraded or blocked for translation by various mechanisms.

反义技术利用DNA或RNA分子通过Watson-Crick碱基配对原则与目的基因的mRNA互补结合，通过各种机制使其降解或抑制其编码蛋白的翻译，从而抑制目的基因的表达。

Methods: A retrospective study was conducted using an insurance database from Bureau of Nation Health Insurance - Central regional branch with registered children born in 2001 who received teeth fluoridation and anti-decay program. The difference of utilization of dental care preventive service analysis was based on each individual child's character and required dental treatment. For cost-benefit analysis, children were selected who were eligible receiving or non- receiving this benefit from July 1, 2004 till 2007. Two groups were compared by frequency matching analysis, based on sex, medical provide territories, insured fee. Additional Incremental benefit/cost method of cost-benefit analysis is also conducted to evaluate the service providing cost increasing and dental treatment cost decreasing effectiveness.

研究方法主要系透过健保局中区分局93年至96年儿童牙科医疗费用统计资料，比较90年次出生之儿童接受涂氟预防保健服务之人口学特质及其涂氟前后牙科医疗利用差异；并依该等对象接受涂氟预防保健服务与否区分两组，就其性别、就医地区别与全民健保投保金额组别等予以配对，进一步应用成本效益分析（cost-benefit analysis，CBA）之增量益本比（Incremental benefit/cost method，IBC），探讨儿童牙齿涂氟预防保健服务成本的增加，使牙科医疗费用减少所带来效益的增加为何。

通过同时对角化算法估计矩阵的联合特征值，获得了参数联合估计的强可辨识性，即允许信号参数在任何一维任意重复，并可以使估计参数实现自动配对。

The pool of unpaired districts varies, making it impossible to grant every district's first choice of partner.

未配对地区的多样性使它不可能同意每个地区的第一选择的夥伴。

And we also research the impact of methylating on hydrogen bond and stacked bond in base pairs under considering water molecules.

研究结果表明，烷基化之所以能造成碱基错配是它可使碱基的质子迁移或烯醇互变现象容易发生，改变原有原子的电荷分布或配对模式，同时碱基自身的互变异构体会跟烷基作用，致使互变异构体能够稳定存在，影响正常碱基配对，引起碱基诱变，造成生理疾病的发生。
