Methods 43 cases of tympani membrane perforated that had been treated by autologous fat transplantation under otic endoscope from 2002-2006,including 10 cases of large perforation of tympanic membrane and 33cases of small ones,were retrospectively analyzed after operation.

The unoperated sides of the treated animals also served as controls. Six normal rats were treated as normal control group. Three different siRNA plasmid solution containing RC2-Ⅰ, MAFbx-Ⅱ, CON (50μl , 0.8μg/μl)was injected and transfected by electroporation as methods mentioned above, respectively. The changes of RC2 and MAFbx mRNA levels and RC2 protein levels after 3 days were determined by real-time quantitative PCR and Western blot, respectively. On postoperative 2, 3 and 4 weeks, the rate of wet muscle weight preservation, mean diameter of muscle fiber and mean cross-section area of muscle fiber and muscle protein content were checked and then compared between group CON and group RC2 or group MAFbx, respectively. The differences between groups were analyzed by one-way ANOVA. Ultrastructural changes of muscle fiber were observed at 2, 3, 4 weeks postoperation.Results GFP plasmid was efficiently deliverd into muscle by electroporation and robust GFP expression in muscle could be observed more than three weeks. Histology shows that injected plasmid DNA diffuses extensively in muscle tissue.

Although perforated and nonperforated appendicitis rates were correlated in men, they were not significantly correlated in women nor were there significant negatie correlations between perforated and negatie appendectomy rates.

这些趋势的不相关性表明穿孔性和非穿孔性阑尾炎可能有着不同的病理生理机制，而抗生素治疗的非手术治疗可能适于初始非穿孔性病例。

METHODS: All appendicitis and appendiceal operations reported to the National Hospital Discharge Surey 1970-2004 were classified as perforated, nonperforated, negatie, and incidental appendectomies and analyzed oer time and by arious demographic measures.

评估非穿孔性和穿孔性阑尾炎以及保守治疗和附带阑尾切除术中的基于人口统计发生率。结果：在1970年至1995年间的非穿孔性阑尾炎发生率下降但随后又增加。

This study used the pick-up head from the commercial DVD-ROM as the basis for optical path, and drilled a 2mm hole on the focusing object lens. After combined with the design of a beams plitter, the laser beam source of the two DVD formed two in-line laser beams. One laser beam passed through the undrilled part, and focused on the surface of the object to be tested, in order to measure the displacement variance of the surface.

於三自由光学测探头的研制上，则将DVD 探头之聚焦物镜做一2mm 的穿孔，於搭配一分光镜的设计后，使个DVD 的光源形成同轴光束，将其中ㄧ光束经由聚焦物镜未穿孔部分，聚焦於待测物表面，用以测待测物表面的位移变化，另一光束则穿透过聚焦物镜穿孔部分，直接将光束投射至待测物表面，作为待测物表面之个角的变化测。

The screen at least partially circumscribes the non-perforated section of the base pipe, and the ribs extend longitudinally in an annular space between the screen and the non-perforated section.

筛管至少部分地围绕基管的未穿孔部分，且肋在筛管与未穿孔部分之间的环形空间内纵向延伸。筛管组件的柔性部件卷绕在肋周围并设置在筛管与未穿孔部分之间的环形空间内。

It is known that perforin plays an important role in the treatment of cancer,virus and parasite.

摘 要 穿孔素是机体发挥细胞毒作用的重要效应物质，在抗肿瘤、抗病毒及寄生虫治疗中有着重要的意义，但它在动物体内的含量极少，不便于进一步研究及新药开发，用基因工程方法来表达生产穿孔素是将小鼠的穿孔素基因在杆状病毒表达系统中进行克隆与表达。

The results show that the effect of small-sized hole and delaminations is not great . On the natural frequencies , the effect of t ransverse elliptical multiple delaminations around an elliptical cent ral hole is more serious than that of lengthways elliptical multiple delaminations around an elliptical cent ral hole ; the natural f requencies are very sensitive to damages location , and less sensitive to multiple delaminations' size and the holes'size.

结果表明：当穿孔和分层的尺寸较小时，其对层合板固有频率的影响很小；横向穿孔-多分层损伤对层合板固有频率的影响较纵向穿孔-多分层损伤更显著；平面编织层合板固有频率对损伤位置最为敏感，分层尺寸次之，穿孔尺寸的影响最弱。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
