长针透刺膝骨关节炎模型大鼠滑膜组织中基质金属蛋白酶3的变化

背景：研究表明基质金属蛋白酶3在关节软骨退变和破坏中有重要意义。目的：观察长针透刺与透明质酸钠治疗大鼠膝骨关节炎后,大鼠化膜组织中基质金属蛋白酶3含量变化。方法：SD大鼠通过膝关节腔内注射1.6%木瓜蛋白酶溶液并驱赶大鼠活动建立膝骨关节炎模型。造模2周后随机分为3组,长针透刺组用直径0.30 mm、长125 mm规格的毫针透刺大鼠犊鼻穴和膝眼穴;药物治疗组关节腔内注射透明质酸钠;模型组不干预。并设立不造模的正常组。结果与结论：治疗4周后,模型组大鼠滑膜组织基质金属蛋白酶3含量较正常组显著升高(P < 0.05),长针透刺组、药物治疗组基质金属蛋白酶3含量较模型组显著降低(P < 0.05),长针透刺组与药物组相近(P > 0.05)。证实长针透刺疗法能有效纠正膝骨关节炎模型大鼠化膜组织中基质金属蛋白酶3的异常表达,这也可能是长针透刺治疗膝骨关节炎的作用原理之一。

Effect of long needle penetration needling on matrix metalloproteinase 3 in the synovium of knee osteoarthritis model rats

BACKGROUND:Studies have shown that matrix metalloproteinases 3 plays an important role in articular cartilage degeneration and destruction.OBJECTIVE:To observe the changes of metalloproteinases 3 expression level in synovium of knee osteoarthritis rats after treated with penetration needling of long needle and sodium hyaluronate.METHODS:SD rats were injected with 1.6% papain solution to knee joint cavity and were driven to exercise in order to construct knee osteoarthritis model. Rats were randomly assigned into 3 groups in the 2nd week after model construction: penetration needling group, drug group and model group. Penetration needling group were treated by penetration needling with filiform needle, with a diameter of 0.30 millimeters and a length of 125 milimeters. Drug group were injected with sodium hyaluronate to knee joint cavity. Model group received no treatment. And non-model control group were established.RESULTS AND CONCLUSION:Content of synovium matrix metalloproteinase 3 in model group was significantly increased than that in the control group (P < 0.05) in the 4th week after treatment. The content of matrix metalloproteinase 3 in penetration needling group and drug group was significantly reduced than that in the model group (P < 0.05). Penetration needling group was similar to drug group (P > 0.05). These findings demonstrate that long needle penetration therapy can effectively correct the abnormal expression of matrix metalloproteinase 3 in synovium of knee osteoarthritis model rats. It may be one of the mechanisms of the treatment of knee osteoarthritis by long needle penetration needling.
