[Shenqi Wenfei Formula alleviates chronic obstructive pulmonary disease in rats with pulmonary qi deficiency syndrome by regulating NLRP3/GSDMD pyroptosis pathway].

ABSTRACT:

Objective

To investigate the effects of Shenqi Wenfei (SQWF) Formula on the NLRP3/GSDMD signaling pathway in pulmonary qi deficiency syndrome rats with chronic obstructive pulmonary diseases (COPD).

Methods

Rat models of COPD and lung qi deficiency syndrome induced by exposure to cigarette smoke and lipopolysaccharide (LPS) injection were randomized (n=8) for treatment with low-, medium- and high-dose SQWF or Yu Ping Feng (YPF). The changes in body weight, grip strength, lung function, pulmonary pathology, peripheral blood inflammatory cell counts, and levels of inflammatory factors in the bronchoalveolar lavage fluid (BALF) were examined. The expressions of proteins associated with the NLRP3/GSDMD signaling pathway in the lung tissues were
