黄芪多糖对糖尿病肾病防治作用机制研究
摘要
随着全球糖尿病发病率的急剧上升，糖尿病肾病作为糖尿病的主要并发症之一，已成为导致终末期肾病的主要原因，严重威胁患者的生命健康，并给社会带来沉重的经济负担。当前，尽管有多种治疗方法，但糖尿病肾病的防治仍面临巨大挑战。黄芪多糖作为传统中药黄芪的主要活性成分，近年来因其广泛的生物活性和药理作用，在糖尿病及其并发症的治疗中展现出巨大潜力。然而，关于黄芪多糖对糖尿病肾病具体防治机制的研究尚不够深入，其临床应用也缺乏系统的理论指导。因此，本研究通过系统回顾和分析黄芪多糖的化学结构、生物活性成分及其药理作用，重点探讨了黄芪多糖对糖尿病肾病的防治机制。研究发现，黄芪多糖具有显著的抗氧化、抗炎、免疫调节和抗纤维化作用，能够保护肾小球结构，促进肾小球滤过屏障修复，调节肾小球内压，减少蛋白尿，改善肾功能，提高肾小管重吸收功能，促进肾细胞修复与再生，抑制炎症反应和纤维化过程。此外，黄芪多糖还能与常规药物和生活方式干预协同作用，提高治疗效果。本研究为黄芪多糖在糖尿病肾病治疗中的应用提供了理论依据，为开发新的糖尿病肾病治疗药物和方法提供了思路。

Abstract
With the sharp rise in the global incidence of diabetes mellitus, diabetic nephropathy, as one of the main complications of diabetes, has become the main cause of end-stage renal disease, seriously threatening the life and health of patients, and bringing heavy economic burden to the society. At present, despite various treatments, the prevention and treatment of diabetic nephropathy still faces great challenges. As the main active ingredient of the traditional Chinese medicine Astragalus, APS has shown great potential in the treatment of diabetes and its complications recently due to its extensive biological activity and pharmacological effects. However, the research on the specific prevention and treatment mechanism of APS on diabetic nephropathy is not deep enough, and its clinical application also lacks systematic theoretical guidance. Therefore, this study focused on the mechanism of prevention and controlling diabetic nephropathy by systematically reviewing and analyzing the chemical structure and bioactive components and their pharmacological effects. Studies found that astragalus polysaccharide has significant antioxidant, anti-inflammatory, immune regulation and antifibrosis, can protect the glomerular structure, promote glomerular filtration barrier repair, regulate the glomerular pressure, reduce proteinuria, improve kidney function, improve renal tubular reabsorption function, promote renal cell repair and regeneration, inhibit inflammation and fibrosis process. In addition, APS can also synergize with conventional drugs and lifestyle interventions to improve the therapeutic effects. This study provides a theoretical basis for the application of APS in the treatment of diabetic nephropathy and provides ideas for the development of new therapeutic drugs and methods for diabetic nephropathy.
