ABSTRACT
Objective:To investigate the differences in matrix metalloproteinases (MMPs) and matrix metalloproteinase inhibitors (TIMPs) from diseased splenic vein (DSVs) and varicose great saphenous vein (VGSVs) under high hemodynamics.Methods:Seventy-two specimens of DSVs,normal splenic veins (SVs),VGSVs,and normal great saphenous vein (GSVs) were collected.Venous wall in the four groups,MMP-2,MMP-9,TIMP-1,and TIMP-2 protein expression were observed and MMP-2,MMP-9,TIMP-1,TIMP-2 proteins positive expression ratio and mRNA expression were determined.Results:DSVs and VGSVs in the two groups,MMP-2,MMP-9,TIMP-1,TIMP-2 proteins with clustered strong expression were observed;In DSVs group,MMP-2,MMP-9,TIMP-1,TIMP-2 protein positive expression ratio and mRNA expression were significantly increased compared with SVs group,while in VGSVs group,MMP-2,MMP-9,TIMP-1,TIMP-2 protein positive expression ratio and mRNA expression were significantly increased compared with GSVs group (P<0.05).VGSVs/GSVs ratio was significantly increased compared with DSVs/SVs ratio (P<0.05).Conclusion:Under high hemodynamics,the dysequilibrium of MMPs and TIMPs from splenic vein and great saphenous vein,These results may be one of the molecular mechanism in vascular remodeling.
