研究目的:

本研究旨在评估DPP-4i磷酸瑞格列汀治疗对伴有认知功能下降风险的2型糖尿病(T2DM)患者血清神经丝轻链蛋白(NfL)和胶质纤维酸性蛋白(GFAP)水平的影响;评估DPP-4i治疗对上述T2DM患者认知功能(包括学习记忆、执行功能等核心领域)的影响。为直接探究DPP4i对T2DM患者神经保护潜力及优化T2DM综合管理策略提供重要证据。  

Objectives of Study:

This study aims to evaluate the effects of the DPP-4 inhibitor retagliptin phosphate on serum levels of neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) in patients with type 2 diabetes mellitus (T2DM) at risk of cognitive decline. Furthermore, it seeks to assess the impact of DPP-4 inhibitor treatment on cognitive function—including core domains such as learning, memory, and executive function—in this patient population. The findings will provide critical evidence regarding the neuroprotective potential of DPP-4 inhibitors and contribute to optimizing comprehensive management strategies for T2DM.
