The degradating and redistributing of ECM were migration of VSMC and vascular remodeling through inhibiting the production of PDGF-BB and the activation of MMPs so to prevent the vascular stenosis.⑤Orthotopic hybridism in situ: The expression of MMP-3 increased after operation, the tendency and intensity were parallel to the expression of NF-κB. Tongxinluo could decrease the expression of MMP-3 and NF-κB. The study showed that the producting and activating of MMP-3 were modulated by NF-κB. The inhibition to the producting and activating of MMp-3 of Tongxinluo was mediated by inhibiting the activating of NF-κB. Conclusion ①The rabbit vascular stenosis model could be established successfully by plain balloon damage, the operation process was easy, economical and practical.
①单纯球囊损伤可成功建立典型家兔血管狭窄模型，操作方法简单，经济实用；②以VSMC增殖、迁移为主的内膜增厚以及以ECM降解、合成与再分布所致的血管重构是导致受损血管狭窄的根本原因；③通心络能明显抑制VSMC的增殖、迁移和ECM降解、合成，阻止血管内膜增生和血管重构，防止受损血管狭窄；该作用可能与其减少和阻止PDGF-BB的产生和活性，以及抑制MMPs的表达和恢复MMPs/TIMPs平衡有关；④通心络能显著抑制球囊损伤后血管内膜增生和血管重构，可能与其保护血管内皮，改善内皮功能，增加血清NO含量有关；⑤通心络抑制内膜增生和血管重构，减轻受损血管狭窄，还可能是通过抑制NF-κB的活化途径而起作用的。
