中文摘要:

目的探讨透骨消痛颗粒防治膝骨性关节炎的作用机制。方法新西兰大白兔50只,采用改良Hulth法复制膝骨性关节炎模型,随机分为6组,分别测定关节液白介素-1(IL-1)、白介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)、基质金属蛋白酶-3(MMP-3)浓度,血清MDA、NO吸光度及关节滑膜SOD活性。结果各实验组8周、16周关节液中IL-1、IL-6、TNF-α、MMP-3,血清NO、MDA均呈高表达,16周时关节滑膜中SOD含量呈低表达状态,与正常组比较差异有显著性(P<0．05,P<0．01)。8周后IL-1、TNF-α、MMP-3、NO、MDA含量,对照组、实验2组、实验3组与模型组比较差异有显著性(P<0．05,P<0．01),对照组、实验1组与实验3组比较差异有显著性(P<0．05);8周后IL-6含量,对照组、实验2组、实验3组与模型组比较差异有显著性(P<0．05);实验1组与实验3组比较差异有显著性(P<0．05)。16周后对照组、实验2组、实验3组与模型组比较差异有显著性(P<0．05,P<0．01);对照组、实验1组与实验3组比较差异有显著性(P<0．05)。结论透骨消痛颗粒通过有效抑制细胞因子、基质金属蛋白酶、氧自由基的生物效应来延缓软骨的退变。

英文摘要:

Objective To investigate the mechanism of Tougu Xiaotong Granula (TXG) on prevention and treatment of knee osteoarthritis. Methods Fifty New Zealand rabbits were randomly divided into 6 groups. Except those in the normal control group, all the rabbits were replicated into knee osteoarthritis model using modified Hulth method. They were administered by gastrogavage once every day respectively with 100 ml of normal saline to the rabbits in the normal group and those in the model group, with 10 g of Zhuanggu Guanjie Pill to those in the control group, and 5 g, 10 g and 20 g of TXG to those in the three TXG tested groups (tested group 1, 2 and 3). The levels of interleukin-1 (IL-1), interleukin-6 ( IL-6), tumor necrosis factor-α(TNF-α) and metalloproteinase 3 (MMP-3) in joint fluid, the blood content of malondialdehyde (MDA) and nitric oxide (NO) absorbance as well as the SOD activity in synovia were observed. Results Overexpressions of IL-1, IL-6, TNF-αand MMP-3 in joint fluid, increased blood content of NO and MDA were shown in the 8th and 16th week, and decreased SOD activity in synovia was shown in the 16th week of the experiment in all the model rabbits, as compared to those in the normal group, the difference was significant respectively (P<0.05 or P<0.01). After 8 weeks of treatment, the levels of IL-1, TNF-α, MMP-3, NO and MDA in the control group, tested group 2 and 3 were significantly different to those in the model group respectively (P<0.05, P< 0.01), and significant difference was also shown in the comparisons of those indexes between the control group and the tested group 1 vs the tested group 3 (P<0.05). As for the level of IL-6, significant difference was shown in comparisons of the model group with the control group, tested group 2 and 3 in the 8th and 16th week of the treatment (P<0.05 or P<0.01), also in comparison of the tested group 3 with the tested group 1 in the 8th week, and in that of the tested group 2 with the control group and the tested group 1 in the 16th week (P <0.05). Conclusion TXG could effectively postpone the degeneration of cartilage through effectively inhibiting the biological effects of cytokines, MMP-3 and oxygen free radical.
