AIM: To study the changes of corneal endothelial cells after viscocanalotomy or trabeculectomy and explore its clinical significance.

目的：探讨角膜内皮细胞在粘性小管切开术或小梁切除术后的变化及临床意义。

Results: MR examination of bone contusion were mostly less than two weeks, but a few patients were longer than one year: STIR, TIWI were more sensitive lesion detection series in hone contusion (100% and 95.7%). Bone contusion mostly occur at knee, and lesions mainly distributed in the margin area of articular (69.8%), in superior portion of vertebral body(74.l%). Bone contusion following-up showed a line-like hyperostosis and osteosclerosis in contusion area. Histological manifestations of bone contusion were local trabecular micro fractures, edema, hemorrhage and injury of fat tissue.

结果：1多数骨挫伤MRI检查在两周内完成，少数病人时间超过1年；2检出骨挫伤敏感的MRI序列为STIR及T1W/I（100%及95.7%）；3膝关节是骨挫伤的好发部位，病灶主要分布于骨边缘区(69.8%)，在脊柱主要分布于椎体上缘终板下(74.1%)；4骨挫伤影像随访提小病变区出现线状骨质修复，骨髓水肿吸收；5骨挫伤病理为骨小梁显微骨折，骨髓水肿、出血和脂肪损伤。

The results show that although the effect of Poisson is one of the factors that led to the cracking of soleplate, but not a major factor. Among the causes of the longitudinal cracks in bottom plate, not only the radical force are considered by traditional theory, but also the warping effect of the box and the local trabecular are serious and can not be ignored.

分析结果表明：泊松效应尽管是导致底板开裂因素之一，但不是主要因素；而底板纵向裂缝的产生除了传统理论所认为的底板连续索所产生的径向力效应外，底板连续索导致的箱梁翘曲效应与局部小梁效应也是重要的、不可忽略的因素。

Results: No fiber layer and inflammatory tissues around any inserted implants were founded. New-grown osteoid tissue appeared faster in Bio-Ti implants than pure titanium and matured bone tissues comprise bone trabecula and Haversian canals appeared in 6 weeks, while at least 12 weeks needed to form matured bone tissue in control groups.

结果：所有种植体周围没有发现明显炎症组织或形成纤维层，Bio-Ti种植体组新生类骨组织生长较快，并于6w时已形成含有骨小梁及哈弗氏小管结构的较成熟骨组织，对照组12w时新生骨组织基本成熟。

New bone trabecula formation could be observed in experiment group, after 8~12 weeks. There were little blood vessel on periphery.

组织切片HE染色观察见对照组无新骨形成，有纤维包裹，实验组8、12周时有新骨小梁形成，周围有较多小血管形成。

Results As compared with control group,the bone trabecula was thinner in experiment group,and the bone structure was rarefaction and disorder, with less bone mass.

结果 与对照组比较，实验组骨小梁纤细，结构稀疏紊乱，骨量少，部分骨小量断裂，成骨细胞和破骨细胞数量均增多，骨陷窝内破骨细胞活跃；骨密度下降。

Trabeculae that those who have been caring for the stray cats on campus to build the houses and feeding time is just like a "little off" This maverick cats do not enjoy it life.

小梁说，已经有爱心人士为校园流浪猫搭建了房屋并且按时喂食，只是像&小断&这样特立独行的猫，不喜欢过那样的生活。

In the period of 8 to 16 weeks after operation,new bone was formed continuously, artificial bone gradually reconstructed to mature lamellar bone,bone trabeculae and medullary cavity,etc. Conclusion The preparation of CPC is simple.

结果 CPC植入后4周有新生软骨形成及未成熟的骨组织，可见大量的软骨细胞、成骨细胞、胶原组织及较多的小血管。8～16周新骨继续生成，人工骨逐渐改建为成熟的板层骨、骨小梁和髓腔结构。

After repairing skull defect using compound implant, X-ray examination demonstrated that space between peripheral sclerotin and compound implant was covered by high-density shadow after 4 weeks.

复合材料植入免颅骨缺损后，X射线观察术后第4周骨缺损外周骨质与复合材料之间大部分被高密度阴影充填，术后第12周骨缺损外周骨质与复合材料之间完全被高密度阴影充填；光镜观察术后第8周骨小梁大部分相连成片，术后第12周骨小梁粗大，骨髓再生。

A new anchorage system for girder to obtain pretension stress at section top-edge in middle of span is shown. Based on the research of bi-prestressing beams inside test-room and the test of the prestress bar character, method for calculating the full size gird and choosing section are proposed. A new-style corrugated pipe which is shown in the paper is used, to solve the transformation of compressed thread bar and the contradiction between loss of friction resistance and pumping in pipe.

本文通过大量的试验及研究分析，提出了双预应力梁跨中上缘获得预拉应力的新的传力锚固体系；通过对室内双预应力混凝土小梁的研究，检测了预压钢筋的受力性能和预压过程中的某些影响参数；提出了足尺梁计算方法和截面、跨径选择方法；研制了新型哑铃型波纹管，很好地解决了预压钢筋变形、摩阻损失和管道压浆之间的矛盾；通过对30？

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
