Research development of scaffolds for engineering cartilage / 国际生物医学工程杂志

Transplantation of engineering cartilage is a better choice for the treatment of articular cartilage lesions.Constructing engineering cartilage needs seeded cells and scaffold materials.The property of scaffold materials has a great influence on the biomechanical features of engineering cartilage.A variety of materials can be used for constructing engineering cartilaginous framework.Exploring the research development of scaffold materials and comparing the effects of their clinical applications is of great significance for further improvement of biomechanical characteristics of the engineering cartilage.

980nm半导体激光减压术治疗椎间盘突出症286例 / 中国康复理论与实践

@#目的探讨980nm半导体激光经皮椎间盘减压术(PLDD)治疗腰椎间盘突出症的疗效。方法286例患者局麻后在C型臂X射线机透视下确定病变椎间盘平面,以每个椎间盘600～800J激光能量行PLDD。参照Choy评分法评价疗效。结果经1年以上随访,0～2分者(优)188例(65.8%),;3～5分者(良)41例(4.1%),6～10分者57例(20%);无椎间盘炎及其他并发症发生。结论PLDD能有效缓解椎间盘源性疼痛。
