Abstract
Objective
To observe the effect of acupuncture plus thunder-fire moxibustion on the expressions of matrix metalloproteinase-3 (MMP-3), tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor-β1 (TGF-β1) in cartilage of knee osteoarthritis (KOA) rats, and to explore the mechanism of acupuncture plus thunder-fire moxibustion in the treatment of KOA.
Methods
Thirty Sprague-Dawley (SD) rats were randomly divided into a blank control group, a model group and an acupuncture-moxibustion group by random digits table, 10 rats in each group. Rats in the model group and the acupuncture-moxibustion group were injected with papain in the right posterior knee joint to prepare the models. The levels of MMP-3 and TIMP-1 in rat synovium of each group were measured by enzyme-linked immunosorbent assay (ELISA) after 2 weeks of treatment. The level of TGF-β1 was determined by Motic B5 Micro-camera system.
Results
The levels of MMP-3 and TIMP-1 in the cartilage of the model group were significantly higher than those in the blank control group (all P<0.01); the levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were lower than those in the model group, and the between-group differences were statistically significant (all P<0.05). The levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were higher than those in the blank control group, and the differences were statistically significant (all P<0.05). The level of TGF-β1 in cartilage tissues of the model group was significantly lower than that in the blank control group (P<0.01); the level of TGF-β1 in the acupuncture-moxibustion group was higher than that in the model group (P<0.05), but it was lower than that in the blank control group, and the between-group difference was statistically significant (P<0.05).
Conclusion
Acupuncture plus thunder-fire moxibustion can effectively recover the abnormal expressions of MMP-3 and TIMP-1 in KOA model rats and somewhat up-regulate TGF-β1, which may be one of its mechanisms of acupuncture plus thunder-fire for KOA.
摘要
目的
观察针刺结合雷火灸对膝骨关节炎(KOA)大鼠软骨组织中基质金属蛋白酶-3 (MMP-3)、基质金属蛋 白酶抑制剂-1 (TIMP-1)和转化生长因子-β1 (TGF-β1)表达的影响, 探讨针刺结合雷火灸治疗KOA的作用机制。
方法
Sprague-Dawley (SD)大鼠30只, 根据随机数字表法随机分成空白组、模型组和针灸组, 每组10只大鼠。模型组和 针灸组予木瓜蛋白酶右后膝关节注射造模。治疗2星期后, 采用酶联免疫吸附法测定各组大鼠滑膜MMP-3、TIMP-1 的含量, 采用Motic B5显微摄像系统测定TGF-β1的含量。
结果
模型组软骨组织中MMP-3和TIMP-1的含量较空白 组显著增加(均P<0.01); 针灸组MMP-3和TIMP-1含量低于模型组, 组间差异有统计学意义(均P<0.05); 针灸组 MMP-3和TIMP-1含量高于空白组, 组间差异有统计学意义(均P<0.05)。模型组软骨组织中TGF-β1的含量较空白组 显著降低(P<0.01), 针灸组TGF-β1含量较模型组升高(P<0.05), 但低于空白组, 组间差异有统计学意义(P<0.05)。
结论
针刺结合雷火灸能有效平衡KOA模型大鼠中MMP-3和TIMP-1的异常表达, 并且对TGF-β1具有一定的上调功 能, 这可能是针刺结合雷火灸治疗KOA的作用机制之一。
