Methods: A total of 94 patients with bladder cancer who received surgical resection in our hospital between February 2015 and June 2017 were selected as the research subjects, and proper amount of bladder cancer lesion and adjacent lesion were collected to detect the expression of miR-21 as well as the mRNA expression of invasion genes and angiogenesis genes. Results: miR-21 expression in bladder cancer lesion was significantly higher than that in adjacent lesion;CDH13 and CBX7 mRNA expression in bladder cancer lesion were significantly lower than those in adjacent lesion while TRAP-1, KPNA2, TRPM8, EDIL3, HGF, VEGF and Epha2 mRNA expression were significantly higher than those in adjacent lesion. CDH13 and CBX7 mRNA expression in bladder cancer lesion with high miR-21 expression were significantly lower than those in bladder cancer lesion with low miR-21 expression while TRAP-1, KPNA2, TRPM8, EDIL3, HGF, VEGF and Epha2 mRNA expression were significantly higher than those in bladder cancer lesion with low miR-21 expression. Conclusion: The high expression of miR-21 in bladder cancer can promote the invasion of cancer cells and the angiogenesis in the lesion.展开更多
