Besides the traditional contents of oral surgery, such as extraction of teeth, alveolar surgery, preprosthetic surgery, TMJ disorders, jaw injuries and salivary gland diseases, additional sections such as microvascular surgery, cosmetic surgery, plastic and reconstructive surgery, head and neck tumour surgery, and Traditional Chinese Medicine are also appurtenant parts of typical oral and maxillofacial surgery of China.

其所涉及的学科领域和内容较西方一些国家更广，除传统的口腔外科——牙及牙槽外科、修复前外科、颞下颌关节病、颌面损伤、唾液腺疾病等外，还包括了颌面整复外科、显微外科、头颈部肿瘤外科等内容，而且还有独特的传统医学——中医学的结合及参与，形成了具有中国特色的口腔颌面外科学。

To sum up, we first conclude that we can isolate mesenchymal stem cells from human fetal articular cartilage and they can be induced to differentiae into several cells under appropriate induction conditions. Anymore, they have their original tissue speciality. Therefore, we first report that mesenchymal stem cells of articular cartilage origin are superior to mesenchymal stem cells of bone marrow origin as seeding cells of cartilage tissue engineering and we provide a kind of new seeding cells of cartilage tissue engineering for the future clinic application.

综上所述，我们首次报道不仅可从人胚胎的关节软骨中获得间充质干细胞，而且软骨来源的间充质干细胞除具有骨髓来源的间充质干细胞的多向分化能力外，还具有其来源的软骨组织特异性，那么，其作为软骨组织工程的种子细胞要优于骨髓来源的间充质干细胞，从而首次提出了一种新型的软骨组织工程的种子细胞，对于未来的软骨组织工程的临床应用提供理论依据。

We tested the knees at flexion angles of 0, 15, 30, 60, and 90with the following applied loads: 10 Nm varus moment, and 5 Nm external and internal rotational torques.21,22 To calculate the force applied in varus rotation testing, we took the desired moment (10 N.m) and divided this by the distance from the joint line to the point of force application in meters.

我们检测了施加力量10N.m的内翻运动和5N.m的外旋和内旋运动，各种运动的膝关节屈曲角度分别为0°、15°、30°、60°和90°。为了在内翻旋转试验时计算施加力，我们采用期望力矩(10M.m)，并将这种力矩分为从关节线到施加力点数米远的距离。

It is an effective and reliable method to treat comminuted subtrochanteric fracture by combining UAEF with limited internal fixation. It has obvious advantages of good reduction and reliable fixation, which is useful for early joint function exercise.

单侧成角度骨外固定架结合有限内固定治疗股骨转子下粉碎性骨折是一种有效可靠的方法，能达到良好的骨折复位，坚强的固定，并可早期行关节功能锻炼。

The lateral tendinous fascicle formed mainly functional anatomic mechanism of the proxinmal interphalangeal joint was extended, and it had close relation to the lateral fascicle and had a coordinated action with the lateral tendon.The lateral tendinous fascicle had also association with the flexor tendinous sheath, and made the flexor tendinous sheath play a role in balancing muscular strength of flexor and extensor.

外侧腱束主要形成伸近节指间关节的功能解剖机制；其与外侧束形成的密切纤维联系而具有协同外侧腱的功能；该腱束与屈肌腱鞘有联系又使其具有平衡屈肌和伸肌肌力的作用。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
