    BackgroundThe aim of this study was to explore expression levels and clinical values of miR-21 and miR-210 in patients with sepsis after burns.MethodsOne hundred and twenty-eight burn patients who were treated in Binzhou Medical University Hospital were selected as research objects, among which 69 complicated with sepsis were in an observation group and 59 complicated with infection were in a control group. MiR-21 and miR-210 expression in the patients' serum was detected by RT-PCR. Serum inflammatory cytokines were detected by an enzyme-linked immunosorbent assay (ELISA). Correlation analysis was used for the correlations of the miR-21 and miR-210 with the cytokines. Receiver operating characteristic (ROC) curves were plotted to analyze the diagnostic values of the miR-21 and miR-210 for sepsis after burns and their predictive values for the poor prognosis of sepsis patients.ResultsMiR-21 expression reduced remarkably and miR-210 expression rose remarkably in the serum of patients with sepsis after burns. According to the analysis of the ROC curves, both of the miR-21 and miR-210 had relatively high diagnostic sensitivity for the disease, but the diagnostic value of their combined detection was higher. Contents of hs-CRP, TNF-α, IL-6, and ICAM-1 in serum were remarkably higher in the observation group than those in the control group. According to the correlation analysis, miR-21 was negatively correlated with the expression of the four cytokines, while miR-210 was positively correlated with that. The predictive value of miR-21 for the prognosis of sepsis patients was not high, but miR-210 had a certain predictive value, and their combined detection had a higher value.ConclusionIn serum of patients with sepsis after burns, miR-21 expression reduces remarkably and miR-210 expression rises. The miR-21 and miR-210 are related to the degree of inflammatory responses in septic patients, and their combined detection has a certain value for diagnosing the disease and predicting its prognosis.Copyright © 2021 Elsevier Ltd and ISBI.
