We analyzed CD31-positive microvessel density and miR-128 expression levels in the glioma tissues using SPSS software, and found that there is a significant inverse correlation of miR-128 levels and the CD31-positive microvessel densities in glioma tissues with Spearman's correlation, r = −0.673 (P<0.05). Here, PECAM1 is linked to central nervous system cancer.
