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。
