Objective To study the relationship between cord blood miR-431 and congenital hearing disorders in neonates, so as to provide reference for clinical prevention and treatment of congenital hearing impairment. Methods From May 2017 to June 2019, 80 neonates with congenital hearing disorder admitted to the Department of Obstetrics and Gynecology, Pidu District People′s Hospital were enrolled as case group, while another 30 neonates with normal hearing were selected into normal group. The threshold of auditory brainstem response(ABR) test, and expression levelsof cord blood miR-431, miR-183 and miR-96 were compared between the two groups. The identification value of miR-431 and miR-183 for mild, moderate and severe hearing disorder was analyzed by ROC curve. Results After click, thresholds of left and right ears in ABR test in case group were significantly higher than those in normal group(t=22.166, 19.741, P<0.05). The miR-431 level in case group was significantly higher than that in normal group, while miR-183 level was significantly lower than that in normal group(t=15.445, 19.607, P<0.05). The miR-431 level in severe hearing disorder group was significantly higher than that in mild-to-moderate hearing disorder group, while miR-183 level was significantly lower than that in mild-to-moderate hearing disorder group(t=10.047,11.816,P<0.05). When the cut-off value of miR-431 was 0.48, the area under the curve(AUC) in discriminating mild, moderate and severe hearing disorder was 0.835(95%CI: 0.735 - 0.908, P<0.001).The sensitivity and specificity were 77.78% and 86.36%, respectively. When the cut-off value of miR-183 was 0.25, the area under the curve(AUC) in discriminating mild, moderate and severe hearing loss was 0.804(95%CI: 0.700 - 0.884, P<0.001).The sensitivity and specificity were 72.22% and 84.09%, respectively. Conclusions The left and right ear ABR thresholds of newborns with congenital hearing disorder are significantly higher than those of normal neonates, while the expression level of miR-431 in cord blood is abnormally up-regulated, while expression level of miR-183 is down-regulated. The miR-431 and miR-183 have better efficacy in discriminating mild, moderate and severe hearing disorder.
