芦丁是一种黄烷醇型多酚,由黄烷醇槲皮素和二糖芦丁糖组成,据报道具有多种生物效应,例如抗氧化和抗炎活性。目前尚不清楚芦丁是否对败血症诱发的心肌病(SIC)具有保护作用。在本研究中,我们使用雄性C57BL/6小鼠和盲肠结扎穿刺(CLP)手术来建立SIC模型。在 CLP 之前,对芦丁进行了预防性治疗(每天 50、100、200 毫克/公斤,7 天)。结果表明,芦丁预处理(每天 100、200 mg/kg,7 天)可降低小鼠败血症的死亡率。我们选择 100 毫克/公斤剂量进行进一步研究。在进行 CLP 之前,对小鼠进行芦丁预处理(每天 100 毫克/千克,7 天),并在 CLP 后 24 小时收集心肌组织和血液样本。芦丁预处理后,肿瘤坏死因子-α (TNF-α)、白细胞介素 6 (IL-6) 和 cTNT 的血清水平降低,而白细胞介素 10 (IL-10) 水平升高。芦丁预处理也减轻了心肌细胞凋亡和线粒体功能障碍。总之,本研究证实了富含芦丁的饮食在预防小鼠模型中 CLP 诱导的心脏凋亡和心脏损伤方面的功效。它为脓毒症 SIC 预防提供了一种潜在的新方法。
Rutin is a flavanol-type polyphenol that consists of flavanol quercetin and the disaccharide rutinose, which has been reported to exert various biological effects such as antioxidant and anti-inflammatory activities. It is not clear whether rutin has a protective effect on sepsis-induced cardiomyopathy (SIC). In this study, we used male C57BL/6 mice and cecal ligation and puncture (CLP) surgery to establish the model of SIC. Rutin was precautionarily treated (50, 100, 200 mg/kg per day, 7 days) before CLP. The results showed that rutin pretreatment (100, 200 mg/kg per day, 7 days) reduced the mortality of murine sepsis. We chose the 100 mg/kg dose for further studies. Mice were pretreatment with rutin (100 mg/kg per day, 7 days) before subjected to CLP, and myocardial tissue and blood samples were collected 24 h after CLP. Serum levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and cTNT decreased, while interleukin-10 (IL-10) increased with rutin pretreatment. The cardiomyocytes apoptosis and mitochondrial dysfunction were also alleviated with rutin pretreatment. In conclusion, this study confirmed the efficacy of rutin-enriched diet in the prophylaxis of cardiac apoptosis and cardiac injury induced by CLP in mouse model. It provides a potential new approach on SIC prophylaxis in sepsis.
