Abstract
it was aimed to discuss the effect of moxibustion (Mox) combined with Bu Fei Qu Yu (BFQY) decoction under the nuclear factor-κB (NF-κB)/transforming growth factor-β1 (TGF-β1)/Smads signaling pathway in the treatment of pulmonary fibrosis (PF). The PF rat models were prepared with bleomycin (BLM). They were divided into the normal (Nor) group, the PF model group (BLM puncture perfusion), the Mox group (grain-sized Mox at the back-shu points and Xuxiao points), the BFQY group (intragastrical BFQY decoction), and the Mox combined with BFQY decoction (Mox+BFQY) group. Lung tissue sections were prepared, and the hematoxylin-eosin (HE) staining and Masson staining were performed to observe the inflammatory response and the degree of PF. The contents of hydroxyproline (HYP), glutathione (GSH), and malondialdehyde (MDA), and the expressions of NF-κB p65, TGF-β1, Smad2, and Smad7 in lung tissues were detected. Compared with those in the Nor group, the inflammatory response score, PF degree score, HYP, GSH, and MDA contents, NF-κB p65, TGF-β1, and Smad2 expressions were significantly increased in the PF group, but Smad7 expression decreased (P<0.05). The above symptoms were significantly improved in the Mox, BFQY, and Mox+ BFQY groups (P<0.05). The effect was more remarkable in the Mox+BFQY group, and there was no significant difference in each index compared with those in the Nor group (P>0.05). Thus, the combined therapy of Mox and decoction had an effect on PF through the NF-κB/TGF-β1/Smads pathway.
