摘要 目的：探讨通络止痛方对人膝关节骨性关节炎(Knee Osteoarthritis，KOA)滑膜成纤维细胞增殖的影响。方法：取本院行全膝关节置换术患者术中废弃滑膜组织，经I型胶原酶消化后进行原代培养，取3～4代成纤维细胞进行高、中、低浓度通络止痛方干预。应用四甲基偶氮唑盐法测定(MTT)法检测KOA滑膜细胞的增殖水平，并用倒置显微镜下观察各浓度下的细胞形态。结果：加药组组间与加药组与空白组比较，差异有统计学意义(P<0.05)。MTT法检测随通络止痛方浓度减小KOA滑膜细胞在490 nm波长处吸光OD值数越大；高中浓度组抑制率为正值，随浓度增加抑制率增大，低浓度抑制率为负值，随浓度降低抑制率减少。结论：高、中浓度通络止痛方对滑膜细胞增殖有抑制作用，低浓度组的通络止痛方对滑膜细胞有增殖有促进作用。

    Abstract Objective：To explore the effect of Tongluo Zhitong Decoction on the proliferation of knee osteoarthritis (KOA) synovial fibroblasts. Methods：The abandoned synovial tissues were taken from patients who had knee replacement surgery in the hospital. The tissues were primarily cultured after digestion in I type collagenase. Three to four generation fibroblasts were taken for high-medium-low concentration intervention. The proliferation of KOA synovial cells was detected by 4-dimethyl-2-thiazolyl)-2 ......
