Concentrations of inflammatory cytokines and nuclear factor-κB (NF-κB) DNA-binding activity. The ventilator-induced lung injury (VILI) group showed a higher tumor necrosis factor-alpha concentration (a) than the lung-protective ventilation (LPV) and PJ34+VILI groups (*P < 0.05) and a higher concentration of interleukin-6 (b) than the PJ34+VILI group (*P = 0.015). NF-κB DNA-binding activities (c) in lung tissue homogenates were higher in the VILI group as compared with the other three groups (*P < 0.05). The PJ34+VILI group showed higher activity than the sham and LPV groups (**P < 0.05). ELISA, enzyme-linked immunosorbent assay.
