Background: QiShen YiQi pills (QSYQ) is a Traditional Chinese Medicine (TCM) formula, which has a significant effect on the treatment of patients with myocardial infarction (MI) in clinical practice. However, the molecular mechanism of QSYQ regulation pyroptosis after MI is still not fully known. Hence, this study was designed to reveal the mechanism of the active ingredient in QSYQ. Methods: Integrated approach of network pharmacology and molecular docking, were conducted to screen active components and corresponding common target genes of QSYQ in intervening pyroptosis after MI. Subsequently, STRING and Cytoscape were applied to construct a PPI network, and obtain candidate active compounds. Molecular docking was performed to verify the binding ability of candidate components to pyroptosis proteins and oxygen-glucose deprivation (OGD) induced cardiomyocytes injuries were applied to explore the protective effect and mechanism of the candidate drug. Results: Two drug-likeness compounds were preliminarily selected, and the binding capacity between Ginsenoside Rh2 (Rh2) and key target High Mobility Group Box 1 (HMGB1)was validated in the form of hydrogen bonding. 2 μM Rh2 prevented OGD-induced H9c2 death and reduced IL-18 and IL-1β levels, possibly by decreasing the activation of the NLRP3 inflammasome, inhibiting the expression of p12-caspase1, and attenuating the level of pyroptosis executive protein GSDMD-N. Conclusions: We propose that Rh2 of QSYQ can protect myocardial cells partially by ameliorating pyroptosis, which seems to have a new insight regarding the therapeutic potential for MI.

본 연구에서는 팔미틴산을 처리한 지방간질환 간세포 모델과 비만/당뇨 동물 모델인 KK/HlJ 마우스를 이용하여 피세아테놀과 레스베라트롤 투여가 염증조절에 주는 영향을 알아보고자 하였다. 4주간의 피세아테놀과 레스베라트롤 섭취는 공복혈당과 경구당부하 검사 2시간 후 AUC를 감소시켜 혈당 조절 개선 효과를 보였다. 또한, 팔미틴산을 처리한 지방간질환 간세포 모델에 피세아테놀과 레스베라트롤을 처리한 결과 염증조절 경로인자인 TLR4와 $NF-{\kappa}B$의 발현을 유의적으로 감소시켰다. 이를 in vivo 비만/당뇨 동물 모델인 KK/HlJ 마우스의 간 조직에서 확인한 결과 피세아테놀 섭취는 NLRP3와 $NF-{\kappa}B$의 간 조직에서의 발현을 유의적으로 감소시켰고, IL-1 발현을 감소시키는 경향을 보였다. 하지만 동량의 레스베라트롤 섭취는 이와 같은 항염증 효과를 보이지 않았다. 결론적으로 혈당 조절 개선 효과와 항염증 효과에 있어 피세아테놀이 레스베라트롤보다 우수한 효과를 가지고, 피세아테놀의 항염증 효과는 혈당 조절 개선 효과에 부분적으로 기여할 것으로 제안한다.
