摘 要:Background Bacterial inflammation is a common complication in patients with leukemia,and sulfur dioxide (SO2) is a bioactive molecule in modulating Gram-negative bacilli *** study aimed to examine the changes in SO2,nuclear factor-κB (NF-κB),and interleukin-8 (IL-8) levels in pediatric acute lymphoblastic leukemia (ALL) with Gram-negative bacterial *** Fifty-five ALL children were enrolled in this study,including 30 males and 25 females,aged 3-13 years,and the median age was 7.8 *** these children who accepted chemotherapy for ALL were divided into the control group (before chemotherapy),the infection group (after chemotherapy with infection),and the recovery group (the infection was controlled after 1 week).The serum level of SO2 was detected using high performance liquid chromatography with fluorescence assay,and NF-κB and IL-8 levels were measured by enzyme-linked immunosorbent assay (ELISA).Human THP-1 cells were cultured,induced,and differentiated into macrophages,which were divided into five groups and each group was cultured with different stimulators:lipopolysaccharide (LPS) group,LPS+L-aspartate-β-hydroxamate (HDX) group,LPS+SO2 group,SO2,and control ***-κB level and IL-8 protein contents by ELISA were examined in each *** In comparison with those of the control group,levels of serum SO2,NF-κB,and IL-8 of the infection group were significantly increased (P 0.05),while those of the recovery group were significantly decreased (P 0.05).A positive correlation was found between levels of serum SO2 and intracellular NF-κB/IL-8,and the correlation coefficients were 0.671 and 0.798 (P 0.05),*** to the results found in human THP-1 cells,levels of NF-κB and IL-8 in LPS group were significantly increased compared with those of the control group (P 0.05); when compared with those in LPS group,levels of NF-κB in LPS+HDX group further increased significantly (P 0.05); however,the NF-κB levels of LP
