Molecular aspects of pathogenesis in osteoarthritis: the role of inflammation

Arthritic diseases cause enormous burdens in terms of pain, crippling, and disability. Osteoarthritis (OA), the most common form of arthritis, is characterized by a slow progressive degeneration of articular cartilage. The exact etiology of OA is not known, but the degradation of cartilage matrix components is generally agreed to be due to an increased synthesis and activation of extracellular proteinases, mainly matrix metalloproteinases. Insufficient synthesis of new matrix macromolecules is also thought to be involved, possibly as a consequence of deficient stimulation by growth factors. Although OA is defined as a noninflammatory arthropathy, proinflammatory cytokines such as interleukin-1 have been implicated as important mediators in the disease. In response to interleukin-1, chondrocytes upregulate the production of nitric oxide and prostaglandin E₂, two factors that have been shown to induce a number of the cellular changes associated with OA. The generation of these key signal molecules depends on inducible enzymes and can be suppressed by pharmacological inhibitors.

关节镜下治疗膝关节骨关节炎

目的：探讨关节镜下治疗膝关节骨关节炎临床疗效．方法：按顺序镜检，切除增生的滑膜，修整退变碎裂的半月板，切除剥脱软骨并修整关节面，摘除游离体．结果：16例均得到随访6～12个月，平均9个月；术后评估优4膝、良15膝、可1膝、差1膝，优良率90．5％．结论：关节镜对骨性关节炎的诊断更全面准确，关节清理术具有疗效可靠、创伤小、并发症少、康复快等优点．手术关键在于要明确术中的治疗重点，有针对性的进行镜下处理，避免因过多的操作而加重对关节的干扰，影响疗效．     

论维吾尔医沙疗对骨质层的转移及力学特性的影响

本文以研究维吾尔医沙疗对骨质层的转移及力学性能的影响为目的,建立好股性关节炎模型的30只新西兰大白兔作为研究对象,由沙疗时间长短之差异将所有兔子分为三组并进行沙疗。在此期间进行四次CT扫描,计算出各股骨骨质层的总体积且统计分析骨质层的转移。取三组兔子左右股骨进行三点弯曲实验。实验结果表明,病态兔子股骨硬质骨和密质骨的增加速度比正常股骨低,而软质骨的减少速度基本一致;软质骨在向硬质骨和密质骨转化;正常兔子股骨的挠度、最大抗弯强度和最大抗弯正应力比病态兔子股骨要高,沙疗会促进股骨骨质层的转化,且改善股骨基本力学性能。     

Molecular basis of osteoarthritis: biomechanical aspects

The unique biomechanical properties of healthy cartilage ensure that articular cartilage is able to transmit force between the joints while maintaining almost friction-free limb movement. In osteoarthritis, the biomechanical properties are compromised, but we still do not understood whether this precedes the onset of the disease or is a result of it. This review focuses on the physical changes to cartilage with age, disease, and mechanical loading, with specific reference to the increased collagen cross-linking that occurs with age (nonenzymatic glycation), and the response of chondrocytes to physiological and pathological loads. In addition, the biomechanical properties and matrix biosynthesis of cartilage from various joint surfaces of the knee and ankle are compared to elucidate reasons why the ankle is less affected by progressive osteoarthritis than the knee.

关节镜下治疗膝关节骨关节炎135例疗效分析

目的：探讨关节镜对膝关节骨关节炎的治疗效果及相关并发症。方法：回顾自2008年3月至2010年3月对135例（139膝）膝关节骨关节炎患者行关节镜下探查清理,并进行跟踪随访6～12个月,平均9．2个月。结果：本组患者优23例（23膝）,良75例（75膝）,可14例（15膝）,差23例（26膝）,优良率为70．5％,并发症13膝。结论：关节镜手术具有微创、安全、术后恢复快、住院周期短等优点,值得临床推广和应用,但需注意严格选择适应症及防范严重并发症。     

骨关节炎滑膜uPA、uPAR、PAI-1表达及意义

探讨尿激酶型纤溶酶原激活物(uPA)及其受体(uPAR)和其抑制剂(PAI-1)在OA的发生发展中的意义。方法:采用免疫组化方法检测OA滑膜组织中uPA,uPAR,PAI-1的表达。结果显示:36例OA滑膜中阳性表达uPA 29例(80.56%)、uPAR 25例(69.44%)P、AI-1 27例(75.00%)。21例对照滑膜中阳性表达uPA 6例(28.57%)、uPAR 6例(28.57%)、PAI-1 3例(14.29%)。实验组与对照组间3种蛋白表达差异均有统计学意义(P<0.05);再将实验组按年龄及软骨破坏程度分组,按年龄分组3种蛋白表达差异均无统计学意义(P>0.05);按软骨破坏程度分组3种蛋白表达差异均有统计学意义(P<0.05)。阳性表达主要分布在滑膜衬里层细胞。结论:uPA系统可能参与介导软骨降解、促进OA的发生发展;而PAI-1则通过抑制uPA活性延缓OA的发生发展。
