现行荷载规范船舶排水量和受风面积的曲线拟合

对港口工程荷载规范2010版中75%保证率下的船舶排水量和受风面积进行了曲线拟合,计算结果与规范计算结 果基本一致,表明了所提出的拟合曲线适用于不同船型的船舶排水量和受风面积计算,为规范中未包括的船型排水量和受 风面积的计算提供了一个更趋于合理、简便、精确的新方法。     

大龄儿童先天性髋脱位的手术治疗

１９８９～１９９４年采用一次性髋臼成形术及股骨旋转短缩截骨术治疗先天性髋脱位１４例（１５髋）。手术时年龄７～１３岁。术后平均随访３年５个月。结果：优９例，良５例，可１例。优良率为９３．３％。作者认为，这种联合手术对治疗大龄儿童先天性髋脱位是一种安全有效的方法。     

Correlation analysis between the interface membrane and loose hip prosthesis

Objective To analyze the cause of prosthesis loosening by observing the interface membranes harvested during the hip restoration operation. Methods A total of 28 specimens of interface membrane around the loose prosthesis were harvested from 28 patients undergoing the restoration of total hip replacement. All the specimens underwent the observation of appearance, light microscopy and scanning electronic microscopy(SEM). Results All the gaps around the loose prosthesis were filled with interface membrane of different thickness. The color of the most interface membrane was madder red, and the other one third of membrane was black. The comparatively thicker membrane was similar to scar connective tissue while the thinner was similar to fiber membrane. A large number of wear debris, macrophages and foreign-body giant cells were found under light microscope. With SEM observation a large number of different diameter collagen fibra structures that looked like scar tissues were arranged disorderly in a great mass, foreign particles and bone debris of different size were distributed unevenly, and the fibroblast was distributed in the collagen fiber. Conclusion Wear debris is related to inflammatory cell response around the interface membrane of the loose prosthesis. The wear debris engulfed by macrophage stimulates the interface membrane to release bone resorption factors (such as TNF) which lead to osteolysis, and this is one of the most important causes of the prosthesis loosening.     

基于AnyBody的髋关节康复训练肌肉力的分析

应用AnyBody软件的AnyScript编程语言建立了完整的人体模型,并且将髋关节康复器械的三维实体模型导入AnyBody中,创建了人体和髋关节康复器械的整体模型,对整体模型进行逆向动力学仿真和肌肉力分析,得到使用髋关节康复器械时髋关节肌肉群肌肉的受力情况和肌肉的活动度．以人体的髂腰肌为例进行分析,获得了髋关节屈曲训练时髂腰肌的受力和收缩情况,受力和收缩在合理范围内,不会造成肌肉拉伤,说明髋关节康复器械能够使髋关节肌肉群的肌肉功能得到有效的康复训练．     

带蹬吊带法治疗先天性髋关节脱位的远期疗效观察

从１９８３～１９８６年，对出生３月至３岁的婴幼儿先天性髋关节脱位８０例，采用吊带（ＰａｖｌｉｋＨａｒｎｅｓｓ）的机能方法进行治疗，近期疗效满意。对其中５６例６５个髋关节的远期疗效进行了随访观察，随访时间６～１１年，平均９．５年。结果：优５６个髋（８６％），良７个髋（１１％），可２个髋（３％）。并发股骨头坏死２个髋（３％），半脱位１个髋（１．５％）。表明采用带蹬吊带法对先天性髋关节脱位进行早期及时治疗，会产生良好效果。     

髋关节假体置换术后并发症及其处理

从1984年以来共处理人工髋关节末后并发症12例。其中感染2例,脱位2例,假体松动与骨折各2例、髋部异位骨化4例。我们认为严重感染病例应及时取出假体,引流伤口,感染控制后第2期置入假体。较轻病例则应积极抗感染,力争保留假体。假体松动常与手术操作技术有一定关系,一旦确诊,须尽平行翻修术。异位骨化症Ⅲ、Ⅳ期病例应手术治疗,术后口服消炎痛或行局部放疗。     

共用引航道船闸下游引航道的平面布置

随着货运量的增大,目前我国正大规模改扩建多线船闸,受枢纽已建建筑物和地形条件限制等多因素影响,新建多线船闸多与已建船闸并排布置,共用引航道。双线船闸共用引航道时,一线船闸充泄水将会影响到另一线船闸引航道水流条件,危及另一线过闸船舶安全及船闸结构安全。结合北江飞来峡船闸水力学模型试验成果,探讨同尺度船闸共用引航道的布置及其对通航水流的影响。结果表明:船闸在错开运行时,通过增大中间辅导墙的扩散角可使水流快速扩散,减小非泄水船闸引航道回流范围和回流强度,可通过优化主辅导墙及下游消能工形式,改善双线船闸引航道水流条件。     

吊带疗法对并发于先天性髋脱位的股骨头坏死的作用

采用带蹬吊带体系治疗婴幼儿先天性髋脱位１５５例１９９髋。对治疗过程中所出现的２２例３０髋股骨头坏死，进行了２～９年连续观察发现：吊带疗法和石膏固定疗法在治疗过程中虽然都有股骨头坏死出现，但头坏死的情况截然不同，前者明显优于后者，吊带疗法有防止、减轻和治疗股骨头坏死的作用。

PAVLIK HARNESS系列疗法治疗小儿先天性髋脱位

自1983年以来我院运用Pavlik Harness治疗3岁以下小儿先天性髋脱位435例497髋,并形成了治疗体系。借助患儿自身的肌肉活动作用,变脱位的不利因素为促进复位的有利因素,使其自动复位。该系列疗法治愈率高,未发现有股骨头无菌性坏死者。
