Systematic Pharmacology-Based Strategy to Explore the Mechanism of Bufei Huoxue Capsule in the Treatment of Chronic Obstructive Pulmonary Disease.

Objective: To explore the effects and mechanisms of Bufei Huoxue Capsule (BHC) on chronic obstructive pulmonary disease (COPD) based on network pharmacology.

Methods: The effective components and related targets of BHC were collected by searching TCMSP, HERB, and ETCM databases, after which the related targets of COPD were obtained on GeneCards and OMIM databases. The common targets were imported into the STRING database and Cytoscape database to construct a target interaction network and screen core targets.

Baicalin inhibits inflammation of lipopolysaccharide-induced acute lung injury toll like receptor-4/myeloid differentiation primary response 88/nuclear factor-kappa B signaling pathway.

Objective: To explore the effect and mechanism of baicalin in the treatment of acute lung injury (ALI) by and experiments.

Methods: ALI was induced by instilling 10 mg/mL lipopolysaccharide (LPS) into the airway of rats. Different doses of baicalin (50 and 100 mg·kg ·d) were administered by gavage one day before modeling.
