In order to further explore the benefits of reasonable exercise on maintaining bone health and examine the effect of exercise on skeleton of young college students, 20 male students of college were divided into exercise group (participates bodybuilding frequently) and control group, some indexes of bone metabolism and bone mineral density were observed and analyzed.

为了进一步论证科学合理的运动有利于维持骨骼的健康和对骨质疏松症的预防作用，揭示体育运动对处于青春后期大学生骨骼的影响，本课题在对部分有关骨代谢的研究成果进行理论研究的基础上，以我校20名男性大学生为实验对象，分为运动组和对照组，观察并分析体育运动对大学生骨密度和骨代谢的影响。

The peak of the bulge accorded with the vertical line through the posterior convexity of superior articular surface of atlas. The superimpose rate of the vertical line with the M line were 48% to left and 65% to right. The surplus existed in l～2mm to lateral of M line. The exit point of screw was the median point of vertical line on the anterior cortex of lateral mass. The superimpose rate of BB line the line linked with the

寰椎后结节中点及上关节突后凸尖下的骨质弧形隆起的顶点可作为寰椎椎弓根螺钉进钉点的准确标志，上关节突后凸尖及横突尖可作为寰椎椎弓根进钉点的大体标志；沿寰椎椎弓根轴线进钉较为安全，内倾17°，仰角变异大，出钉参照前结节顶点；椎动脉沟中外的厚度及进钉点处寰椎后弓的高度是寰椎椎弓根螺钉固定的主要限制性因素。

"It is far more sensitive than radiography for bone erosion in patients with early rheumatoid arthritis, and can detect pre-erosive features, such as osteitis and synovitis, along with tendonitis and potentially other MRI features that can be used to predict which patients will go on to severe destructive joint damage and irreversible functional disability," Dr.

Peterfy医师进一步指出，对於早期类风湿性关节炎病患而言，MRI在骨质糜烂的诊断上，远比X光摄影灵敏许多，且可侦测到糜烂前的特徵；像是骨炎与滑膜炎、连同肌腱炎与可用於预测严重破坏性关节损害及无法恢复的功能障碍，能一开始就向病患展现准确的预测，进行一个有效率的病患管理是非常重要的。

BACKGROUND: Establishment of individual femoral model can describe the stereochemical structure of femoral accurately, which is conductive to measuring femoral anatomic forms. This model possesses unified standard, and removing the potential confounding factors, thus, it is more suitable for biomechanical test.

摘要背景：个体化股骨模型的建立，能够准确、完整地描述出股骨的立体结构，有助于测量股骨的解剖形态，这样的模型有统一的密度和机械性能，去除了个体之间性别、年龄、种族、骨质疏松程度、是否有骨病等混杂因素，用于生物力学测试更有意义。

OA was caused in the rabbit by resecting the cartilage between diaphsis and condyle of proximal tibia.

针对临床中大量的继发性膝关节OA病例，孟和教授强调了生物力学在病因学、病理学及治疗学中的重要地位：&尽管有酶类及免疫反应的参予降低了关节软骨的屈服强度，但要磨损到骨质外露却离不开应力的作用&。
