加压

Objective: To explore the value of different surgicalmethods in the treatment of the displaced femoral neck fracture of the elderly.analyse joint function, complications, reversion factors Methods: An follow up study was done on 71 cases older than 60years who were treated with internal fixation, femoral head arthrop lasty and total hip joint replacement between 2000 and 2005 to compare the difference upon operation time, blood loss, duration of hospi-talization , joint function evaluation one and two years after operation , complications and reversionrate.

目的：探讨加压空心螺钉内固定术、人工股骨头置换术和人工全髋关节置换术在治疗老年人移位性股骨颈骨折中的临床价值。分析术后髋关节功能、并发症、二次手术或翻修率等相关因素。方法：对2000—2005年于长春中医药大学第一附属医院骨科收治的71例60岁以上移位性股骨颈骨折患者进行了随访研究，比较AO加压空心螺钉内固定术、人工股骨头置换术和人工全髋关节置换术在手术时间、出血量、住院时间、术后下地时间、术后12个月和24个月的髋关节功能评价、并发症以及二次手术率方面的差异。

Interfragmentary technique (see Chapter 50) should be used for screw fixation of the medial malleolus to proide compression across the osteotomy site.

内踝的螺丝钉固定应使用骨折断端间加压技术(见50章)，以在截骨面上加压。

Interfragmentary technique (see Chapter 50) should be used for screw fixation of the medial malleolus to provide compression across the osteotomy site.

内踝的螺丝钉固定应使用骨折断端间加压技术(见50章)，以在截骨面上加压。

The function of flexion and extension of metacarpophalangeal and inter～phalangeal joints were achieved satisfactorily.

因此骨片钉除微小螺纹钉加压作用外，后端增粗的钉杆和小垫片可起到双重加压作用。

Results With compression plate fixation,the amount of bone morphogenic proteinin the wounded region was more than that with mini-plate at every stage.

结果 在不同时间内，加压侧骨形成蛋白阳性着色比不加压侧强，分布广。

Methods 68 cases with femoral peritrochanteric fracture from January, 2002 to December, 2007. 25 were treated by Gamma nail, 25 of them were treated by DHS, DCS and 18 of them were treated by HCS.

2002年1月～2007年12月收治的股骨转子间骨折并通过手术治疗的68例，采用Gamma钉固定25例、滑动加压鹅头钉固定25例与空心加压螺钉固定18例。

These three internal fixations of femoral peritrochanteric fracture were differ. For example, Gamma nail is less harmful, better clinical treatment, shorter in shape and stronger in anti-hip inversion. DHS, DCS have a better treatment and are stronger in anti-hip inversion but more harmful and excessive bleeding, and HCS, which is named Minimally Invasive Surgery, is the least harmful, less bleeding, suitable for old patients and the patients of tolerance of poor operation, but poor in anti-hip inversion.

3种不同方法内固定治疗转子间骨折具有各自的特点，Gamma钉具有手术损伤小及良好的临床疗效力臂短对抗髋内翻的能力强；滑动加压鹅头钉具有良好的临床疗效及相对坚强的抗内翻能力，但手术损伤相对较大，失血量较大；空心加压螺钉固定的手术损伤最小，属于微创手术方法，可经皮完成，手术出血少，适用于高龄及手术耐受性差的患者，但抗髋内翻的能力最差。

Thirdly, the precipitation phenomena and pH-curves of the compressed COi-ethanol-water system with BSA or lysozyme were studied, and it was found that: BSA would precipitate when pH of solution decreased close to isoelectric point, and the precipitate would redissolve when pH decreased further.

蛋白质分子结构数据表明，乙醇还在一定程度上改变了蛋白质分子的表面结构，这影响到了蛋白质的缓冲能力等特性，从而乙醇对加压CO_2-乙醇-水-蛋白质多元体系的pH变化有降低的作用，这使体系可处理的蛋白质浓度较加压CO_2-水-蛋白质体系大幅度提高。

Result:Altogether uses this method to treat 10 examples patients, completely belongs to the serious open smashing bone fracture, moreover all is outside the bone reveals, as a result of the osteomyelitis, the bone not company, the durable each kind of conventional surgery and the treatment has not attained successfully, the use bulk body emaciated by sickness excision, outside the bracket fixing pressurizes the compression to be fixed, simultaneously is doing the epiphysis end with the needle saw which independently develops to dive the good truncation bone, restores excises the body emaciated by sickness the length.

结果： 共用此方法治疗10例病人，全部是属于严重开放性粉碎性骨折，而且都是骨外露，由于骨髓炎、骨不连，经用各种常规手术及治疗未获成功，使用大块病骨切除，外固定架加压压缩固定，同时在干骺端用自行研制的针锯目的：探索治疗胫骨骨髓炎、骨不连的新方法。方法：将病灶病骨大块切除，用外固定支架缩短加压固定病骨切除骨的两断端，同时在干骺端用自行研制的针锯潜行截骨，用同一支架进行缓慢延长，恢复肢体长度。

Requirements and the accuracy of pressure element were analyzed in theory, and the experimental results tallies basically with it.

实验所得的加压精度与理论分析结果比较接近，加压装置的压力与变形之间基本呈线性关系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
