Abstract:

BACKGROUND: Matrix metalloproteinase inhibitor 1 plays an important role in the inhibition of articular cartilage degeneration and destruction.

OBJECTIVE: To observe the changes of matrix metalloproteinase inhibitor 1 expression level in synovium of knee osteoarthritis rats after treated with penetration needling of long needle.
METHODS: A total of 40 Sprague-Dawley rats were randomly assigned into normal group, penetration needling group, drug group and model group, with 10 rats in every group. 1.6% papain solution was injected into knee joint cavity of Sprague-Dawley rats. 2 weeks later, knee osteoarthritis models were established. Rats in the normal and model groups did not receive any intervention. In the penetration needling group, rats were treated by penetration needling with 0.3 mm×125.0 mm filiform needle. Rats in the drug group were intraarticularly injected with sodium hyaluronate.
RESULTS AND CONCLUSION: (1) Enzyme linked immunosorbent assay: at 4 weeks after treatment, matrix metalloproteinase inhibitor 1 expression in synovial membrane was higher in the normal group than in the model group (P < 0.05). Matrix metalloproteinase inhibitor 1 expression in synovial membrane was higher in the penetration needling group and drug group than in the model group (P < 0.05). (2) Results verified that long needle penetration therapy can effectively increase matrix metalloproteinase inhibitor 1 expression in synovial membrane of knee osteoarthritis model rats.
