Metabolic syndrome (MetS) includes central obesity, hypertension, insulin resistance, and dyslipidemia and is closely related to nonalcoholic fatty liver disease, atherosclerotic cardiovascular disease (CVD) and type 2 diabetes mellitus, involving multiple causative factors. Current drug therapies for intervention and amelioration of MetS are essential in clinical treatment of metabolic disease. In this report, we proposed an H-modified montmorillonite (H-MMT) using an acid modification method with ultrafine structure and super absorption ability as a potential drug for MetS. Hamsters fed a high-fat diet were orally treated with H-MMT and simvastatin was applied as a control. H-MMT lowered lipids by decreasing intestinal absorption and promoting lipid excretion, subsequently preventing obesity, fatty liver, and hyperlipidemia. Moreover, H-MMT was significantly safer and better tolerated by the liver compared to simvastatin, which was hepatotoxic. In addition, we found that H-MMT had protective effects on gastric mucosal damage. Therefore, this versatile H-MMT provides a potential strategy to effectively improve MetS and provide gastric mucosal protection in clinical applications.
代谢综合征(MetS)包括中心性肥胖、高血压、胰岛素抵抗和血脂异常,与非酒精性脂肪肝、动脉粥样硬化性心血管疾病(CVD)和 2 型糖尿病密切相关,涉及多种致病因素。目前,针对代谢综合征的干预和改善的药物治疗在代谢性疾病的临床治疗中至关重要。在本报告中,我们提出了一种 H 修饰蒙脱石(H-MMT),它采用酸改性方法具有超精细结构和超强的吸收能力,可作为治疗代谢综合征的潜在药物。用高脂肪饮食喂养的仓鼠通过口服 H-MMT 进行治疗,并应用辛伐他汀作为对照。H-MMT 通过减少肠道吸收和促进脂质排泄来降低血脂,从而预防肥胖、脂肪肝和高脂血症。此外,与具有肝毒性的辛伐他汀相比,H-MMT 对肝脏的安全性和耐受性明显更好。此外,我们发现 H-MMT 对胃黏膜损伤具有保护作用。因此,这种多功能的 H-MMT 为有效改善代谢综合征和提供胃黏膜保护提供了一种潜在的策略,可在临床应用中使用。
