Objective: To observe the effects of Qi supplement and blood activation prescription (QB)and its disassembled prescriptions medicated serum on the secretion of matrix metalloproteinase (MMP) 9 and MMP-2 by human umbilical vein endothelial cells (HUVEC) post-transfected pcDNA3.1-VEGF165. Method: Constructing pcDNA3.1-VEGF165 restructuring plasmid
then it was transient transfected in HUVEC with Fugene HD transfection reagent. Prepare QB and its disassembled prescriptions medicated rat serum
saline normal serum. Seed the post-transfected HUVEC with 5% serum. The expression of VEGF was detected by using Western Blot. The expression of MMP-2 and MMP-9 were detected by using enzyme-linked immunosorbent assay. Result: (1)The expression of vascular endothelial growth factor(VEGF) in the QB group is higher than the saline group. There is a significant difference between the two groups(P<0.01). The expression of VEGF in the Blood Activation (BA) group and the Qi supplement (QS) group are lower than the QB group. Both groups have statistically significant difference when compare with the whole group(P<0.01). (2)Either the secretion of MMP-2 in the QB group or in the BA group is higher than the saline group. Both groups have statistically significant difference when compare with the Saline group(P<0.05
P<0.01). The secretion of MMP-2 in the QS group is lower than the QB group. There is a significant difference between the two groups(P<0.01). (3)The secretion of MMP-9 in the QB group and its disassembled prescriptions group are higher than the Saline group. Only the whole group and the BA group have significant with it(P<0.01
P<0.05). The secretion of MMP-9 in the disassembled prescriptions groups is lower than the whole group. Both groups have significant with the whole group(P<0.01). Conclusion: QB can not only promote the expression of VEGF
but also increase the secretion of MMP-9 and MMP-2. BA plays a main role in this. The therapeutic angiogenesis mechanisms of QB may be related to increase the secretion of MMP
