Objective To investigate the roles of microRNA143(miRNA143) and microRNA133 a(miRNA133 a) in the diagnosis of bladder cancer. Methods There were 50 patients with bladder cancer(bladder cancer group),60 patients with non-bladder tumor(disease control group) and 60 healthy subjects(healthy control group). The levels of miRNA133 a and miRNA143 in urine of bladder cancer group before and after surgery and control groups were determined by polymerase chain reaction(PCR). Receiver operating characteristic(ROC) cu...
