The testing was performed under axial load(25N～150N) on each group. The stress changes of the caudad (C5/6,C6/7) zygapophyseal joint was tested .

结果 1。在轴向加载下，下位节段关节突关节内的压力随着施加载荷的增大而增大。

However, it is not known how orthodontic force influences the function of cementoblast and what is the relationship between the function change of cementoblast with root resorption. So we studied the effect of mechanical stimuli on root resoption by examining the expression OPG and RANKL and exploring the related signal transduction pathway in cementoblast. Methods: Cementoblasts OCCM30 were cultured in DMEM with 10% FBS for 48 hours and starved in DMEM with no FBS for 24 hours, then subjected to mechanical strain by four-point bending system with tension and compression stress at 2000μstrain at 0.5Hz frequency. The flow cytometry was used to examine the cell cycle and proliferation activity after 3h, 6h, 12h, 24h loading respectively. OPG and RANKL mRNA were analysed with real time quantitive RT-PCR after the same loading period as FCM.

本课题利用四点弯曲力学加载系统，采用流式细胞术、实时荧光定量PCR、Western免疫印迹等方法，研究体外培养的成牙骨质细胞株OCCM-30在不同力学环境中增殖活性的变化，以及其表达骨保护素和破骨细胞分化因子的mRNA的变化，探讨应力刺激对成牙骨质细胞表达破骨细胞分化调控蛋白的影响，并通过对应力刺激下成牙骨质细胞分裂原活化蛋白激酶家族中的ERK1/2、P38MAPK活性的变化及其与OPG、RANKL基因表达变化关系的研究，对力学刺激调节破骨细胞分化调控蛋白的相关上游信号转导通路进行初步探讨。

It showed that deformation twins had formed in 2Cr17Mn15Ni2N and 304L targets, despite the peak pressures induced by LSP were no more than one third and half of the critical stress for twinning of corresponding targets. Different types of microbands and dislocations configurations were observed in the two targets. The features of dislocations slip deformation induced by ultrahigh strain rate followed FCC metallic crystallology. No deformation martensite phase was discovered.

On the basis of the elastic-plastic analysis of the crack tip zone under cyclic loading, suggested by Rice, the general expression for the delayed retar- dation parameters and the delayed retardation formula, containing the four parameters, were proposed by using Matsuoka model.

基于Rice对循环加载下裂纹尖端的弹塑性分析，按照Matsuoka模型理论，提出了迟滞参数的一般表达式和四参数迟滞公式，并对本文的试验结果及Matsuoka的试验结果进行了分析讨论。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
