Abstract:
Objective To investigate the relationship between serum levels of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) and Suzuki' s grading system in adult moyamoya disease (MMD).Methods Fifty-two adult patients with MMD,who were diagnosed in Jinling hospital between April 2009 and January 2010,were retrieved from the Nanjing Stroke Registry Program (NSRP).Sixteen sex- and age-matched healthy individuals with MMD patients consisted of the control group.Using enzyme-linked immunosorbent assay,serum concentrations of VEGF and MMP-9 were compared between adult MMD patients and healthy individuals.By Suzuki' s six-grading system,patients were divided into different subgroups,and the correlation of serum levels of VEGF and MMP-9 corresponding to different subgroup and Suzuki's grading was respectively analyzed.In addition,the correlation of serum levels of VEGF and MMP-9 was also evaluated.Results Serum VEGF concentrations in ischemic and hemorrhagic MMD patients was respectively ( 289.4 + 69.2 ) pg/ml and ( 324.3 ± 95.6 ) pg/ml and were significantly higher compared to those in healthy controls ( ( 63.5 ± 7.6 ) pg/ml; F =69.43,P ＜ 0.01 ).Similar findings were observed for MMP-9 ( ( 499.4 ± 76.2 ) ng/ml and ( 531.2 + 100.2 ) ng/ml versus (257.1 ±30.7) ng/ml; F =66.023,P ＜0.01 ).With the increase of Suzuki' s grading,serum levels of VEGF and MMP-9 respectively showed a high trend ( r =0.879,P ＜ 0.01:r =0.838,P ＜ 0.01 ).In addition,a positive correlation between serum levels of VEGF and MMP-9 was found in the MMD group( r =0.590,P ＜0.01 ).Conclusion The results show that serum levels of VEGF and MMP-9 in adult MMD are higher than those in healthy controls,which may play a role in neovascularization in MMD,and moreover,serum levels of VEGF and MMP-9 show a high trend with the progression of MMD,which suggest that serum levels of VEGF and MMP-9 can reflect the severity of MMD.
