摘要"对话糖尿病"是一个世界性的糖尿病学术论坛.2008年第五届论坛的主要议题是2型糖尿病治疗新靶点,并特别介绍了当今糖尿病治疗领域的热点--肠促胰岛激素,尤其是胰高血糖素样肽1(GLP-1)与β细胞功能的研究进展.研究结果提示在胰岛素抵抗的背景下,β细胞功能持续减退是2型糖尿病进展的典型特征.由于GLP-1具有葡萄糖依赖性降糖作用且可改善β细胞功能,目前已成为学者们探索糖尿病治疗途径的新靶点.由诺和诺德公司研发的GLP-1类似物--利拉鲁肽(Liraglutide)正是针对上述糖尿病治疗新靶点的药物之一.大量研究证实利拉鲁肽不仅具有高效、持久的降糖效果,且可以显著改善β细胞功能.这些研究结果增强了人们使用GLP-1或GLP-1类似物治疗糖尿病的信心,使利拉鲁肽成为具有广阔前景的抗糖尿病药物.

abstracts"Diabetes Dialogue" is an international forum of latest cutting-edge research on diabetes. The major topics in the 5th event in 2008 were the novel targets in the treatment of type 2 diabetes. In particular, the latest developments in incretin-based therapies, especially glucagon-like peptide-1 (GLP-1) -based therapies, and their effects on the β-cells have been provided. Studies suggested that type 2 diabetes is characterized by progressively deteriorated β-cell function with the presence of insulin resistance. Owing to its glucose-dependant glucose lowering effect and the effect on improvement of β-cell function, GLP-1 has become the novel target of therapies. Liraglutide, a GLP-1 analogue developed by Novo Nordisk, is one of the novel therapies in the treatment of type 2 diabetes. Many studies have demonstrated that liraglutide showed both an efficacious and sustained effect on glycemic control and a significant improvement of 13-cell function. As a result, recently the role of GLP-1 or GLP-1 analogue in the management of type 2 diabetes has gained more popularity and liraglutide is considered as a promising drug in the treatment of type 2 diabetes.
