研究目的:

0Hz-taVNS 治疗 MCI 临床随机对照双盲(患者及数据分析者盲)研究,获得疗效证据。比较 40Hzγ波频段 taVNS 和 sham taVNS 治疗 MCI 的疗效差异,证明 40Hz-taVNS 能有效改善 MCI 患者记忆、语言等相关症状。 (2)采集 MCI 及 HCs 组形态及功能脑数据。包括 MRI 的 T1WI、BOLD、ASL、DTI 和 EEG 数据。分析 taVNS 如何调节 MCI 脑结构、脑功能、脑血流、类淋巴,以及激发大脑γ波振荡。 (3)检测外周血炎症因子及 MCI 标志物。抽取外周血化验 MCI 标记物 Aβ40、Aβ42、p-tau181 以及炎症因子 IL-1β、IL-6,IL-8 和 TNF-α,分析 taVNS 是否能改变 MCI 的血液生物标记物,调节炎症因子。 (4)采用相关性及中介分析方法,揭示 taVNS 如何调节多维度生理生化指标,改善 MCI 症状的复杂机制。分析明确 MCI 脑功能、结构、脑血流、类淋巴变化,与炎症因子、生物标记物变化存在的多因素相关及因果关系。

Objectives of Study:

Clinical randomized controlled double-blind (patient and data analyser blind) study of 40Hz-taVNS in the treatment of MCI obtained evidence of efficacy. The difference of efficacy between 40Hz gamma-wave band taVNS and sham taVNS in the treatment of MCI proves that 40HZ-TAVNS can effectively improve the memory language and other related symptoms of MCI patients. (2) Morphological and functional brain data of MCI and HCs groups were collected. T1WI BOLD ASL DTI and EEG data from MRI were included. To analyze how taVNS regulates MCI brain structure brain function cerebral blood flow lymphoid and stimulates brain gamma wave oscillation. (3) Peripheral blood inflammatory factors and MCI markers were detected. Peripheral blood samples were collected for MCI markers Aβ40 Aβ42 p-tau181 and inflammatory factors IL-1β IL-6 IL-8 and TNF-α to analyze whether taVNS can change the blood biomarkers of MCI and regulate inflammatory factors. (4) Correlation and mediation analysis methods were used to reveal the complex mechanism of how taVNS regulates multi-dimensional physiological and biochemical indicators and improves MCI symptoms. The multi-factor correlation and causal relationship between brain function structure cerebral blood flow and glymphatic changes of MCI and the changes of inflammatory factors and biomarkers were analyzed and confirmed.
