摘要
In the face of the elevated incidence and mortality rate of septic shock in the ICU,this retrospective study seeks to investigate the indicative and predictive value of high-mobility group box 1(HMGB1)and miR-146b in patients with septic shock.Quantitative RTPCR was employed in this study to quantify the HMGB1 and miR-146b levels in plasma samples obtained from the patient group and healthy controls.The investigation involved the comparison between the two groups and tracking changes in the patient group over time.The finding revealed that upon admission,the patient group exhibited markedly elevated relative expression levels of HMGB1,which subsequently decreased over time.Conversely,the patient group displayed significantly reduced relative expression levels of miR-146b upon admission,which subsequently increased over time compared to the control group.Receiver operating characteristic(ROC)curves showed good predictive value for HMGB1 and miR-146b.The experimental results suggest that HMGB1 and miR-146b serve as valuable and convenient biomarkers for evaluating the severity of septic shock and predicting mortality.Additionally,it is proposed that serum miR-146b may be inducible and potentially exerts a negative regulatory effect on the expression of HMGB1.
