Protective Effect of Jianpiyifei II Granule against Chronic Obstructive Pulmonary Disease via NF- κB Signaling Pathway.

Protective Effect of Jianpiyifei II Granule against Chronic Obstructive Pulmonary Disease via NF-κB Signaling Pathway. Evid Based Complement Alternat Med. 2018;2018:4265790 Authors: Fan L, Chen R, Li L, Liang Z, Yu X, Huang K, Yin S, Wu L, Chen Y, Xu Y, Wang Q, Lin L Abstract Jianpiyifei II granule (JPYF II) is an oriental herbal formula used clinically in China to treat chronic obstructive pulmonary disease (COPD). The aim of the present study was to investigate the anti-inflammatory and antioxidative activities of JPYF II in a mouse model of COPD induced by lipopolysaccharide (LPS) and cigarette smoke (CS) and in RAW264.7 cells stimulated with cigarette smoke extract (CSE). Mice were given LPS via intratracheal instillation on days 1 and 15 and exposed to CS generated from 4 cigarettes/day for 28 days. The mice were treated with 0.75, 1.5, or 3 g/kg/d JPYF II by intragastric administration in low, middle, and high dose groups, respectively, for two weeks. RAW264.7 cells were stimulated by CSE and treated with JPYF II at doses of 12.5, 25, or 50 μg/mL. In the mouse model of LPS and CS-induced COPD, JPYF II decreased inflammatory cell counts in broncho alveolar lavage fluid (BALF), in addition to mRNA expression of proinflammatory cytokines and metalloproteinases (MMPs) in lung tissues. In addition, JPYF II elevated catalase (CAT) and glutathione peroxidase (GSH-Px) activities and reduced the levels of malondialdehyde (MDA) and...
