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.

Under the different pH conditions, the migration and transformation behavior of each form of phosphorus released from the lake sediments into water body was studied by means of simulation. The results show that under alkalic condition or acidic condition, the temporal and spatial distribution of phosphorus in the water body changes with its releasing mechanism, and its migration and transformation behaviors are various. The change of pH value has no obvious effect on such transformation, but the total phosphorus in the water body has substantial effect on the concentration change of various forms of phosphorus.
