Comparison of expression levels of p-p38 MAPK, NF-κB65, p-IκB-α, IkB, HIF-1α, Nrf2 and TGF-β1 using western blotting. A: Representative graphs of protein expression of p-p38 MAPK, NF-κB65, p-IκB-α, IkB, HIF-1α, Nrf2 and TGF-β1 (a: control group, b: paraquat group, c: Xuebijing + paraquat group, d: dexamethasone + paraquat group). B: statistical analysis of protein expression of p-p38 MAPK, NF-κB65, p-IκB-α, IkB, HIF-1α, Nrf2 and TGF-β1. Data are expressed as mean ± SEM. **P < 0.01 compared with control group; ^# P < 0.05 compared with paraquat group; P > 0.05 Xuebijing + paraquat group compared with dexamethasone + paraquat group.
