研究目的:

本研究以抑郁症缓解期残留认知功能障碍的患者为主要研究对象,探索: 1.探究其在tACS干预前后θ-γ耦合(TGC)的变化以及和认知功能变化之间的相关性; 2.进而明确在该人群中,额顶叶TGC的变化在抑郁症缓解期残留认知功能障碍中的作用机制。  

Objectives of Study:

This study primarily focuses on patients with residual cognitive impairments during remission from depression to investigate: 1. Changes in theta-gamma coupling (TGC) before and after tACS intervention and its correlation with cognitive function changes; 2. The role of frontal-parietal TGC changes in the mechanism underlying residual cognitive impairments during depression remission in this population.

Randomization Procedure (please state who generates the random number sequence and by what method):

Randomization was performed using the random number table method in SAS software (SAS Institute, Inc., Cary, NC). Trained nurses opened opaque sealed envelopes containing each subject's group assignment code prior to the first intervention and administered tACS.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

纸质数据,主要指入组受试者的临床评估的各类量表(THINC it、PDQ-D、HAMD-17等)。统一保存至十四病区总务间,专柜上锁保存。按照测试时间(如基线、治疗一周后)分别保存。每个受试者的单次测试的所有纸质数据应一起装订,用SPSS软件统计分析。 电子数据,主要指入组受试者的电子病例和记录的WCST和stroop(统称SST)任务。保存在试验专用电脑的固定路径中。固定路径设置为和“D盘—>tACS-SST”。每个被试的数据单独保存为以其名字命名的一个文件夹。每次(周)的数据在被试文件夹内单独保存,以时间命名,如“基线”、“第一周”。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

CRF refers to various clinical assessment scales completed by enrolled subjects (e.g., THINC it, PDQ-D, HAMD-17). These are uniformly stored in the locked cabinet within the general affairs room of Ward 14. Data are organized by assessment time point (e.g., baseline, one week post-treatment). All paper-based data from a single assessment session for each subject should be bound together for statistical analysis using SPSS software. EDC primarily refers to electronic case records and the WCST and Stroop tasks (collectively termed SST) of enrolled subjects. These are stored in a fixed path on the trial-dedicated computer. The fixed path is set as "D: drive -> tACS-SST". Each subject's data is stored separately in a folder named after the subject. Data from each session (or week) is stored within the subject folder in a separate folder named according to the time point, e.g., "Baseline," "Week 1."
