Both Fas and NO can lead chondrocyte apoptosis respectively and cause articular cartilage destruction. IGF-Ⅰ, TGF-β, bFGF, BMP and other growth factors are polypeptide agents that can influence cell activity by signal convection. They can accelerate chondrocyte proliferation and proteoglycan synthesis, play the local regulation action on formation and plerosis of bone and cartilage tissue by autocrine or paracrine. They have the ability to induce cartilage formation. Some investigations showed that growth factors can influence chondrocyte metabolism, synthesis of specific Ⅱ type collagen and proteoglycan by co-operation and inhibition. 1. 3 Situation of OA therapeutics The therapeutic methods of OA mainly comprised non-drug treatment, drug treatment, operation treatment, tissue and genetic engineering, et al. Drug treatment is the chief method among them.

若其活性发生改变，则将导致关节软骨基质成分的丢失和进行性破坏；软骨细胞凋亡与OA的发病密切相关，Fas与NO可各自独立介导软骨细胞凋亡，造成关节软骨破坏；IGF-Ⅰ、TGF-β、bFGF、BMP等生长因子是一组通过细胞间信号传递影响细胞活动的多肽因子，具有促进细胞生长、增殖与合成等作用，可通过自分泌或旁分泌方式对骨和软骨的形成和修复起局部调节作用，可促进软骨细胞增殖、分化与蛋白多糖的合成，具有较强的诱导软骨形成的能力，研究表明多种生长因子相互促进、相互抑制，以协同或拮抗方式影响软骨细胞代谢，影响软骨细胞特异性Ⅱ型胶原和蛋白多糖的合成分泌。

Concentrations of Pyr in cartilage and subchondral bone changed with the progress of OA, which perhaps connected with the high excretion of Pyr in urine.

OA关节软骨及软骨下骨的Pyr含量随病程发生变化，可能是造成经尿液排Pyr升高的原因。

Method］Six intact human cadaver lower extremities were used to produce calcaneal intraarticular fracture models, fracture patterns of the model were observed with radiographical technique, and anatomical study was proceeded to observe the fractures and their effects on soft tissues and compartments in foot.

方法］选用6个新鲜的成人足标本，采用多功能生物力学测定仪建立跟骨关节内骨折模型，通过X线片和CT检查确定骨折的发生并观察骨折的形态，解剖观察骨折的走行及其对足部相关软组织、骨筋膜室的影响。

In four patients, osteoarthritic changes were observed at the radiohumeral joint.

有4例病例在肱桡骨关节处发生骨关节炎改变。

Anterior-posterior and lateral radiographs of the hip were taken to observe radiotransparent region and sclerosis, prosthesis dislocation, attachment of prosthesis and the femur and prosthesis stability.

常规摄髋关节正侧位X射线片，了解假体与骨界面是否有透光区和硬化带，观察假体是否有移位发生以及假体与股骨的接触情况、假体固定的稳定性。

Background: With the proliferation of different fixation screws, there is an increasing trend to recommend early internal fixation of the broken scaphoid een if the fracture is not displaced.

对于轻微移位或未移位的舟骨骨折进行早期内固定，过度治疗的比率会很高，增加了手术并发症发生的几率。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
