摘要

Renal ischemia–reperfusion injury (RIRI) is a primary cause of acute kidney injury (AKI), frequently resulting in high mortality rates and progression to chronic kidney disease (CKD). This study aimed to investigate the therapeutic potential of total saponins from Panax notoginseng (PNS) in the context of RIRI. Utilizing a murine RIRI model, the efficacy of PNS was evaluated, demonstrating a significant reduction in renal inflammation and cellular pyroptosis. Furthermore, PNS was found to modulate the ROCK2/NF-κB signaling pathway, thereby attenuating the inflammatory response. Importantly, in vitro experiments with hypoxia/reoxygenation cell models corroborated these findings, showing that PNS inhibited pyroptosis and regulated the ROCK2/NF-κB pathway. This research underscores the therapeutic potential of PNS in the treatment of RIRI, providing a robust scientific basis for its consideration as a prospective clinical therapy.
