Some approved aneugens Trip terygiuwlIypogaucum (evelHutch, colchicine, thiabendazole, a tropine sulfate,d-ubocurarine was added into the reactive system respectively and the changes of their absorption values were taken down during different periods under the conditions of 37 0C and 350nm .

本研究通过多步聚合和解聚合反应从猪脑中分离纯化微管蛋白，建立微管蛋白的体外聚合和解聚合反应平衡体系，并将已证实的非整倍体诱发剂（昆明山海棠根部水抽提物、2-（4′-噻唑）苯丙咪唑、硫酸阿托品、d-筒箭毒碱）分别加入此反应平衡体系中，于37℃、350nm条件下，记录此体系不同时期的吸光值变化，与阳性对照物和溶剂对照处理平衡体系后的吸光值在相同时间点作比较，以此评估这几类非整倍体诱发剂对离体条件下的微管蛋白聚合的影响，寻求这几类非整倍体诱发剂是否可通过抑制微管蛋白聚合作用途径而诱发非整倍体。

TGF-β1 was mainly expressed in renal tubular epithelial cells, and there was no differece between proximal tubule and distant tubule. The expression of TGF-β1 was also increased with the development of tubulointerstitial lesions.

TGF-β1的表达亦主要见于肾小管上皮细胞，在近曲小管和远曲小管之间无明显的差异，TGF-β1的表达量也随着肾小管间质损害程度的加重而增加。

Methods: Fifty four teeth with 54 interacanal fractured instrument were endodontically treated using G-G bur with ultrasonic techinque under dental operating microsc. The unsuccess rates were calculated and analysed.

收集2006年11月～2007年12月间根管内折断器械共计54例（54个根管），在根管手术显微镜下用G-G钻结合超声技术处理，记录折断器械在根管中的分布以及根管中的位置，分析失败病例的原因。

Experiment result indicates that the RFHP has greater thermal diffusivity, and can reduce junction-to-case thermal resistance of the module. When power density is 176W/cm^2, the temperature difference on the condensation section is within 3℃. The longer time period for the chip to reach the same temperature during RFHP module start-up can avoid power uprush and raise the ability of resisting thermal impact.

结果表明：与铜基板相比，径向平板热管具有更高的热扩散能力，可降低模块的结壳热阻；热管冷凝面具有良好的等温性，当芯片功率密度为176W/平方公分时，热管冷凝面的温差在3℃以内；热管模块启动过程中芯片达到相同温度需要的时间长，有利于克服功率"飙升"和提高功率器件抗热冲击的性能。

Methods 169 patients underwent subclavian venepuncture in the treatment of bone marrow transplantation.78 of them were designed as study group and 91 patients as control group.In study group,the technique of inserting catheters was improved as comparison as routine method.

In order to decrease the hydraulic pressure in the expandable tubular operation and enhance the HSE standard, the paper analyze the two kinds of working condition the expansion operation in vertical and horizontal holes respectively.

为了研究膨胀管补贴技术中降低膨胀压力的方法，降低作业压力，提高作业安全性，理论分析了膨胀管补贴作业中的两种典型工况：直井膨胀管补贴、水平井膨胀管补贴。

The thesis discusses three eigenvalues individually and explains the pressure wave propagation of three modes, includes wave speed, wave decay and energy distribution. Since the elastic potential energy occupies more than 98% of mechanical energy in the arteries, which is larger than 2% of kinetic energy of flowing blood. Else join elastic wall and wall of managing having a viscid condition to analysis .
