摘要
二甲双胍作为2型糖尿病治疗的一线药物，其多重作用机制近年来受到广泛关注。本研究旨在系统探讨二甲双胍在改善胰岛素抵抗、调节能量代谢及潜在抗炎和抗氧化作用中的具体机制。通过整合体内外实验数据与临床观察结果，结合分子生物学技术分析关键信号通路的变化，发现二甲双胍主要通过激活AMPK通路抑制肝脏葡萄糖生成，同时促进肌肉组织对葡萄糖的摄取与利用。此外，研究揭示了其对肠道菌群结构的调节作用，以及通过降低慢性炎症水平间接改善代谢功能的创新机制。结果表明，二甲双胍的作用不仅局限于血糖控制，还涉及心血管保护和延缓并发症发生等多方面效益。本研究为深入理解二甲双胍的药理机制提供了新视角，并为其在更广泛代谢性疾病中的应用奠定了理论基础。关键词：二甲双胍；AMPK通路；胰岛素抵抗；肠道菌群；抗炎作用
Exploration of the Multiple Mechanisms of Metformin in the Treatment of Type 2 Diabetes Mellitus
Abstract
Metformin, as the first-line drug for treating type 2 diabetes, has recently garnered significant attention due to its multiple mechanisms of action. This study aims to systematically investigate the specific mechanisms by which metformin improves insulin resistance, modulates energy me tabolism, and exerts potential anti-inflammatory and antioxidant effects. By integrating in vitro and in vivo experimental data with clinical observations, and employing molecular biology techniques to analyze changes in key signaling pathways, it was found that metformin primarily activates the AMPK pathway to suppress hepatic glucose production while promoting glucose uptake and utilization in muscle tissues. Furthermore, the study revealed its regulatory effects on gut microbiota composition and an innovative mechanism through which it indirectly improves me tabolic function by reducing chronic inflammation levels. The results indicate that metformin's effects extend beyond glycemic control, encompassing cardiovascular protection and delaying the onset of complications. This research provides a new perspective on the pharmacological mechanisms of metformin and establishes a theoretical foundation for its application in a broader range of me tabolic diseases.
