Background/Aims:
Stroke is a major cerebrovascular disease threatening human health and life with high morbidity, disability and mortality. It is aimed to find effective biomarkers for the early diagnosis on stroke.
Methods:
The expressions of 17 previously reported stroke-associated miRNAs were measured using quantitative RT-PCR and the expressions of plasma high-sensitivity C reactive protein (hs-CRP) and serum interleukin 6 (IL-6), the pro-inflammation markers in brain injury, were examined using enzyme-linked immunosorbent assay in 128 acute ischemic stroke (AIS) patients and control group.
Results:
Serum miR-146b expression was significantly increased within 24 hours after stroke onset in patients compared with control group. In addition, the upregulation of serum miR-146b was strong positively correlated with plasma hs-CRP, infarct volume and National Institutes of Health Stroke Scale (NIHSS) score, and moderate positively correlated with serum IL-6 of patients. Importantly, the combination of plasma hs-CRP and serum miR-146b gained a better sensitivity/specificity for prediction of AIS (AUC from 0.782 to 0.863).
Conclusion:
Our preliminary findings suggested that upregulated serum miR-146b in acute ischemic stroke might be a potential biomarker for AIS evaluation.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
