The external fixator was a good, economical, effective and simple method in the treatment of femoral neck fracture. The three pins used in fixation of femoral neck fracture are important. The placement of the pins should be in accordance with the compressive trabeculae and clingy to the femoral calcar.

3动力髋螺钉虽然在固定强度上优于其它各组，但却由于手术创伤大、对股骨头残存血供破坏较大等缺点而限制了其应用；自行设计的外固定支架为一种简单、有效、实用、经济的固定方法，有一定的推广价值；穿针方向应循压力骨小梁方向尽量贴近股骨距低角度倒三角形钻入才符合生物力学原理。

Cross section of the beam was divided into layers, in which each layer might have different materials, but its properties were assumed to be constant over the layer thickness.

Histological observation: Four weeks after implantation, porcine cancellous bone scaffold/bone marrow stromal cells complex appeared new bone formation and scaffold's degradation, which significantly increased in 8 weeks; In 12 weeks, new bone continued to increase and changed gradually to mature bone, a small amount of the Havers system was seen, the trabecular bone was not typical, capillary proliferated obviously, few residual scaffolds were seen, and no inflammatory cells were observed.

组织学观察：猪松质骨支架/骨髓基质干细胞复合体植入后4周开始有新骨生成，支架开始降解；8周时新骨的形成及支架的降解都明显增加；12周时新骨继续增加，逐渐向成熟骨组织转变，可见少量哈佛系统，但骨小梁尚不典型，毛细血管增生明显，少量支架残留，未见炎症细胞。

The amount of trabecular meshwork pigmentation was not a significant predictor as well.

At this time, loosen the connection screw of standard section with spanner, hang the shaft of hand crane on the upper angle bar, sway the shaft of hand crane upward, separate this standard section from the next section, and lay it in the suspension coop, dismantle the other standard section for the same method, and turn the shaft to another direction, draw the lifting wire rope tightly, the operation staff leave the suspension coop, open the lock stopping instrument, fall the suspension coop to next position and lock the brake instrument, the operation staff return to the top of suspension coop, continually dismantle note: forbid the staff leave on the top of suspension coop or in the coop when the suspension coop is running

8.1折除时，首先将吊笼用停层装置停靠在待拆除的标准节的下两节上，操作人员上到吊笼顶，卷扬机松绳，用小吊杆将顶梁略向上提起，拔出顶梁横销，使顶梁值得徐徐降下，降到拆除节下一节中间框架角处，并重新穿上横销，这时用板手将标准节连接螺栓松开，将手摇起重机小吊杆钩挂在待拆节上框架用钢土，到吊笼内，用同样的方法拆下另一节标准节，然后将吊杆转向不影响升降机运行的方向，收紧起升钢丝绳，操作人员离开吊笼，打开锁止机构，使吊笼下降到下一个拆除位置，并将锁止机构锁死，人员重返笼顶，进行下一拆除循环注意：在吊笼运行时绝不允许有人员留在吊笼顶部或吊笼内

The results show that, for the first with no headwall, when there is no crosswind, it has small front face areas, so the aerodynamic resistance is the least. Since the second and the third have headwall, the front face areas are large, so they have bigger aerodynamic resistance. Under the condition of crosswind, as the third design option has the highest side beam, the area of positive pressure at the upwind is bigger, and the area of negative pressure is smaller when the bigger eddy area appears, so the side forces become larger. The first has the least side forces; the overturning moment of the first is the least.

研究结果表明：在无横风情况下，方案一中没有端墙，迎风面积较小，受到的气动阻力最小，方案二和三中平车有端墙，迎风面积较大，受到的气动阻力也较大；有横风情况下，方案三中平车侧梁较高，车体迎风面正压区较大，而背风侧产生较大的涡流区，在此区域内压力较小，故其横向力较大，方案一中平车侧梁没有加高，受到的横向力最小；方案一中平车倾覆力矩最小，稳定性最好。

Look for active bass chasing baitfish onto the shallow ends of the points and bars and fish fast-moving baits that can work well around current, such as a lipless crankbait.

The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.
