Serum expression levels of Mb and NT-proBNP and NF-κB expression in neutrophils in patients with MODS and the clinical significance.

This study was designed to investigate the expression of myoglobin (Mb), N-terminal pro-brain natriuretic peptide (NT-proBNP) in serum and the expression of nuclear factor-κB (NF-κB) in neutrophils in patients with multiple organ dysfunction syndrome (MODS) and the clinical significance. From July 2014 to December 2015, 314 patients with severe disease were selected during their stays at the emergency ward of the Third People's Provincial Hospital of Henan Province (Zhengzhou, China). Seventy patients with MODS were selected as MODS group, 108 patients with single organ or system injury were selected as the key prevention group, and 136 patients without obvious organ or systemic injury were selected as prevention group. Serum levels of Mb and NT-proBNP were measured by ELISA. Neutrophils were isolated by flow cytometry, and the activity of NF-κB in neutrophils of MODS patients was measured by electrophoretic mobility shift assay (EMSA). At 1, 7 and 14 days after treatment, the levels of Mb, NT-proBNP and NF-κB in the three groups were significantly reduced compared with pretreatment levels (p<0.05). Logistic regression analysis showed that serum Mb, NT-proBNP and NF-κB activity were positively correlated with the progression of the disease (r=0.809, 0.785 and 0.833, p=0.012, 0.025 and 0.004), and negatively correlated with the treatment time (r=-0.773, -0.734 and -0.815; p=0.033, 0.041 and 0.078). Mb, NT-proBNP and NF-κB may be involved in the pathogenesis and development of MODS, and may play an important role in the prevention and treatment of MODS.
