BACKGROUNDS: Acute lung injury (ALI) is a lethal condition characterized by uncontrolled pulmonary inflammatory responses, with high morbidity and mortality rates that pose a significant threat to patient health. The persistent retention of neutrophils in lung tissue and subsequent inflammatory damage represents a primary mechanism underlying the early onset of ALI disorders. In recent years, pharmaceutical research targeting these pathological processes has garnered considerable attention. Traditional Chinese medicines (TCM) and their active ingredients, known for their safety and stability, show promising potential in treating ALI through their ability to modulate neutrophil function via multiple pathways.
PURPOSE: This review examines the mechanisms of neutrophil involvement in the pathogenesis of ALI, investigates potential therapeutic targets and pathways through which Chinese medicines and their active ingredients regulate neutrophil function, and provides a theoretical foundation for developing novel clinical treatment strategies.
METHODS: A comprehensive literature search was conducted using multiple databases, including Science Direct, PubMed, Google Scholar, and Web of Science. Search terms included 'lung injury,' 'acute lung injury,' 'inflammatory lung injury,' 'inflammation,' 'active ingredient,' 'herbal,' 'traditional Chinese medicine,' 'mechanism,' 'drug,' and 'neutrophils.' The selected literature was systematically categorized and analyzed.
RESULTS: Our review reveals that TCM and active ingredients influence neutrophil function through four primary mechanisms to impede ALI progression: 1) reduction of neutrophil-mediated uncontrolled inflammatory responses by suppressing neutrophil hyperactivation and inhibiting neutrophil migration and infiltration; 2) attenuation of lung tissue inflammatory damage by inhibiting neutrophil-produced cytotoxic substances, including elastase granules, neutrophil extracellular traps (NETs), and reactive oxygen species (ROS); 3) suppression of inflammatory responses by decreasing the secretion of neutrophil-derived cytokines, such as interleukin (IL) -1β, IL-6 and tumor necrosis factor-alpha (TNF-α); and 4) enhancement of neutrophil phagocytosis and accelerate the removal of apoptotic neutrophils to eliminate harmful pathogens and promote late-stage tissue repair. These findings demonstrate that Chinese medicines and their active ingredients exhibit significant therapeutic potential in ALI disorders through the modulation of neutrophil function, providing a robust theoretical framework for their clinical applications.
CONCLUSION: Traditional Chinese medicines and their active ingredients demonstrate significant anti-inflammatory efficacy through multiple mechanisms of neutrophil function regulation, showing considerable promise for the treatment of ALI with broad clinical applications.
