Abstract

Chuanfangyihao (CFYH) is an effective treatment for acute lung injury (ALI) in clinical practice; however, its underlying mechanism of action remains unclear. Therefore, the aim of the present study was to elucidate the pharmacological mechanism of action of CFYH in ALI through experimental validation. First, a rat model of ALI was established using lipopolysaccharide (LPS). Next, the pathological changes in the lungs of the rats and the pathological damage were scored. The wet/dry weight ratios were measured, and ROS content was detected using flow cytometry. ELISA was used to examine IL‑6, TNF‑α, IL‑1β, IL‑18, and LDH levels. Immunohistochemistry was used to detect Beclin‑1 and NLRP3 expression. Western blotting was performed to analyze the expression of HMGB1, RAGE, TLR4, NF‑κB p65, AMPK, p‑AMPK, mTOR, p‑mTOR, Beclin‑1, LC3‑II/I, p62, Bcl‑2, Bax, Caspase‑3, Caspase‑1, and GSDMD‑NT. The mRNA levels of HMGB1, RAGE, AMPK, mTOR, and HIF‑1α were determined using reverse transcription quantitative PCR. CFYH alleviated pulmonary edema and decreased the expression of IL‑6, TNF‑α, TLR4, NF‑κB p65, HMGB1/RAGE, ROS, and HIF‑1α. In addition, pretreatment with CFYH reversed ALI‑induced programmed cell death. In conclusion, CFYH alleviates LPS‑induced ALI, and these findings provide a preliminary clarification of the predominant mechanism of action of CFYH in ALI.
