基于肠道菌群及其代谢产物短链脂肪酸防治1型糖尿病的研究进展

1型糖尿病（T1DM）是由T淋巴细胞介导的胰岛β细胞被定向破坏的慢性自身免疫性疾病，多发于儿童和青少年。研究发现，肠道菌群及其代谢产物短链脂肪酸（SCFAs）在T1DM的预防和治疗中发挥重要作用，肠道菌群调节将为T1DM的防治提供新的思路和方法。本文综述了肠道菌群及其代谢产物SCFAs防治T1DM的研究进展，探究SCFAs、膳食纤维、益生菌和益生元、肠道菌群移植及中药治疗改善T1DM的研究现状，为临床应用提供参考。

Research Progress in the Prevention and Treatment of Type 1 Diabetes Mellitus Based on Intestinal Flora and Its Metabolite Short-chain Fatty Acids

Type 1 diabetes mellitus is a chronic autoimmune disease in which directed destruction of pancreatic β cell mediated by T lymphocytes.It is more common in children and adolescents.Studies have shown that the intestinal flora and its metabolites short-chain fatty acids play an important role in the prevention and treatment of T1DM.The regulation of intestinal flora will provide new ideas and approaches for the prevention and treatment of T1DM.This article reviews the research progress of the intestinal flora and its metabolites SCFAs in the prevention and treatment of T1DM and explors the current research status of the T1DM improvement by SCFAs，dietary fiber，probiotics and prebiotics，intestinal flora transplantation and Chinese medicine treatment，which providing reference for clinical application.
