Stimulatory effects of ARDS patient’s BALF on human monocytic cells. It showed that 6 histone-related cytokines were all notably increased in the supernatant of ARDS BALF-treated human monocytic U937 cells, whereas addition of anti-histone H4 antibody or heparin could decrease these cytokine levels (all p < 0.05). Variables were expressed as mean ± standard deviation (SD)
