a. The protein expression levels of IL-6 and TNF-α were assessed by western blotting analysis in sham (0 g, 2.0 g) and PH-LHD model (0 g, 2.0 g) rats’ pulmonary vein, *P < 0.05 vs. S1, # P < 0.05 vs. M1. b. The protein expression levels of IL-6 and TNF-α in PH-LHD model rats’ pulmonary vein treated with SAC/MAPKs inhibitors were assessed by western blotting analysis, *P < 0.05 vs. M2
