Myocardial damage is a major consequence and a significant contributor to death in cases of sepsis, a severe infection characterized by a distinct inflammatory response and a potential threat to the patient's life. Recently, the effects of intestinal microbiota and serum metabolites on sepsis have garnered increasing attention. Herein, the effects of golden bifid treatment upon cecal ligation and puncture (CLP)-induced sepsis in mice as a model for myocardial dysfunction were explored. Our results demonstrated that golden bifid treatment partially improved myocardial dysfunction and apoptosis, cardiac inflammation and oxidative stress, and intestinal mucosal permeability and barrier dysfunction in CLP-induced sepsis mice. The intestinal microbiota diversity and abundance were also altered within sepsis mice and improved by golden bifid treatment. Mucispirillum schaedleri, Acinetobacter baumannii and Lactobacullus intestinalis were significantly correlated with heart damage markers, inflammatory factors, or oxidative stress indicators. Serum differential metabolite levels were also significantly correlated with these parameters. Altogether, golden bifid treatment might be an underlying approach for treating sepsis-induced myocardial dysfunction and highlight the underlying effect of intestinal microbiota and serum metabolites on the pathogenesis and treatment of sepsis-triggered myocardial dysfunction.
心肌损伤是脓毒症的主要后果和重要死亡原因,脓毒症是一种严重的感染,其特征是明显的炎症反应,对患者的生命构成潜在威胁。最近,肠道微生物群和血清代谢物对脓毒症的影响引起了越来越多的关注。本研究旨在探讨金双歧治疗对盲肠结扎穿孔(CLP)诱导的脓毒症小鼠模型心肌功能障碍的影响。结果表明,金双歧治疗部分改善了 CLP 诱导的脓毒症小鼠的心肌功能障碍和细胞凋亡、心脏炎症和氧化应激、以及肠道黏膜通透性和屏障功能障碍。金双歧治疗还改变了脓毒症小鼠的肠道微生物群多样性和丰度。Mucispirillum schaedleri、鲍曼不动杆菌和乳杆菌与心脏损伤标志物、炎症因子或氧化应激指标显著相关。血清差异代谢物水平也与这些参数显著相关。总之,金双歧治疗可能是治疗脓毒症引起的心肌功能障碍的一种潜在方法,强调了肠道微生物群和血清代谢物对脓毒症引起的心肌功能障碍发病机制和治疗的潜在影响。
