摘要

Spontaneous intracerebral hemorrhage (ICH) is a common and severe neurological disorder that has been associated with high rates of mortality and morbidity. It is urgent to find new biomarkers for the early diagnosis and prevention of ICH. In recent years, micro-RNAs (miRNAs) have been proved to play an important role in vascular damage and inflammation in cerebrovascular diseases, including ICH. In the peripheral blood, circulating miRNAs will be present at a remarkably steady level. In the present study, we explored the circulating plasma microRNA (miR)-181b, miR-223, miR-155, and miR-145 as new potential biomarkers for the diagnosis of ICH. The plasma samples from 106 patients with ICH and 50 patients without ICH (control group) were collected and subjected to quantitative real-time polymerase chain reaction analyses for the expression levels of circulating miR-181b, miR-223, miR-155, and miR-145. The expression levels of plasma circulating miR-145 (P < 0.001), miR-223, and miR-155 were increased in patients with ICH compared with those in the control group (P < 0.05). However, the expression of plasma circulating miR-181b was decreased in patients with ICH compared with that in the control group (P < 0.001). Receiver operating characteristic curve analyses were performed to determine the diagnostic sensitivity and specificity of miR-145 and miR-181b to detect ICH. The area under the curve for miR-145 was 0.766 (95% confidence interval, 0.689–0.838) and for miR-181b was 0.78 (95% confidence interval, 0.70–0.86), suggesting that circulating miR-145 and miR-181b can be used to differentiate patients with ICH from those without ICH. Our results have shown that measurement of circulating miR-181b, miR-223, miR-155, and miR-145 in plasma samples could serve as a potential noninvasive tool for ICH detection.
