Abstract

Hedyotis diffusa Willd (HDW) is a constituent of several Chinese medicines used clinically to treat inflammatory diseases, including airway inflammation. The aim of the present study was to investigate whether HDW serves a protective role in suppressing chronic airway inflammation and its underlying mechanisms. A mouse model of chronic smoking was induced via exposure to cigarette smoke (CS) for 30 days, increasing the exposure time for up to 5 min per day and the administration of lipopolysaccharide (LPS). Mice were gavaged with HDW (50 or 100 mg/kg body weight), dexamethasone (1 mg/kg body weight) or normal saline (NS, 0.9%) 1 h prior to CS challenge. Compared with CS and LPS (SL)‑induced mice, the levels of interleukin (IL)‑1β, tumor necrosis factor‑α and transforming growth factor‑β in bronchoalveolar lavage fluid from HDW+SL mice were significantly decreased and IL‑10 was markedly reduced. Histological examination of the lung tissues revealed that HDW treatment alleviates airway inflammation. In addition, the administration of HDW to human bronchial epithelial BEAS‑2B cells suppressed the activity of the nuclear factor (NF)‑κB signaling pathway. The results of the present study demonstrate that HDW has a therapeutic effect in COPD and the underlying mechanism may be attributed to inhibition of the NF‑κB pathway.
