Expression and Significance of microRNA-3686 in Peripheral Blood of Patients with Refractory Epilepsy

The study is to investigate the expression and significance of microRNA-3686 in peripheral blood of refractory epilepsy patients (RE). 83 patients with untreated epilepsy were selected as the experimental group. During the treatment, According to diagnostic criteria for refractory epilepsy, 15 patients were diagnosed with refractory epilepsy (RE group) and 68 cases in no refractory epilepsy group (NRE group). 50 patients in the normal group were selected as the control group. The results showed that the expression of microRNA-3686 in the peripheral blood of the experimental group was lower than that of the control group (P < 0005). The levels of P-gp and MRP1 in peripheral blood of patients in RE group were higher than those in NRE group (P < 0005). microRNA-3686 was negatively correlated with P-gp (r = -00799, P < 0005), and had no correlation with MRP1 (r = 00279, P = 00314); ROC curve showed microRNA-3686 prediction RE of the area under the curve of epilepsy AUC was 0.733, 95% CI (0.603-0.863), (P < 0005). In Conclusion the microRNA-3686 is low in peripheral blood of patients with refractory epilepsy and may be involved in the resistance of epilepsy by regulating P-gp but not MRP1.
