干预措施:

Interventions:

组别:

真耳迷走神经刺激组

样本量:

15

Group:

Active taVNS Group

Sample size:

干预措施:

1.刺激位点:耳甲腔三角窝,迷走神经耳支(ABVN)核心分布区; 2.核心刺激参数:耳迷走神经刺激仪TENS-200A(苏州医疗器械有限公司),频率20Hz(7S)、4Hz(3S),两者交替;波宽0.2ms;刺激强度为受试者可耐受的最大麻刺感,无尖锐疼痛感; 3.干预时长与频率:双耳轮流刺激,每次刺激20分钟,每日3次,连续干预4周(28天),总计168次刺激。

干预措施代码:

Intervention:

1.Stimulation Site: Cavum conchae and triangular fossa of the auricle , the core distribution area of the auricular branch of the vagus nerve (ABVN) . 2.Core Stimulation Parameters: Transcutaneous auricular vagus nerve stimulation device TENS-200A (Suzhou Medical Devices Co., Ltd.). Stimulation was delivered in an alternating pattern: 20 Hz for 7 s and 4 Hz for 3 s; pulse width 0.2 ms. Stimulation intensity was set to the maximum tingling sensation tolerable by the subject, without sharp pain. 3.Intervention Duration and Frequency: Stimulation was applied alternately to both ears, 20 minutes per session, 3 times daily, for 4 consecutive weeks (28 days), totaling 168 stimulation sessions.

Intervention code:

组别:

伪耳迷走神经刺激组

样本量:

15

Group:

Sham taVNS Group

Sample size:

干预措施:

1.刺激位点:耳屏,无迷走神经耳支分布; 2.刺激参数与干预流程:设备外观、操作界面、刺激时长、每日干预频率、总干预周期与试验组完全一致,仅输出极低强度的瞬时电信号,仅产生轻微皮肤触感,无有效迷走神经刺激效应; 3.操作培训与质控要求:与试验组完全一致,确保盲法有效性。

干预措施代码:

Intervention:

1.Stimulation Site: Tragus of the auricle, an area without distribution of the auricular branch of the vagus nerve. 2.Stimulation Parameters and Intervention Protocol: The device appearance, operation interface, stimulation duration, daily intervention frequency, and total intervention period were identical to those in the experimental group. Only an extremely low-intensity instantaneous electrical signal was delivered, producing a mild cutaneous sensation without effective vagus nerve stimulation. 3.Operator Training and Quality Control Requirements: Consistent with those of the experimental group to ensure the validity of blinding.

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:

一、具体数据采集方法 1. 采集人员要求:参与数据采集的研究人员均经过统一培训,熟练掌握CRF填写规范、EDC系统操作流程及各项数据采集标准,明确不同指标的采集时间、采集方法及记录要求,避免因操作不规范导致的数据偏差。 2. CRF采集流程:采用标准化纸质CRF,在受试者招募完成后、干预开始前后,采集人口学资料(性别、年龄、学历等)、基线临床特征。 3. EDC采集流程:采集人员在CRF填写完成并审核通过后,及时将数据录入EDC系统,录入过程中严格对照CRF内容,确保录入数据与原始记录一致;系统自动完成数据实时校验和逻辑核查,对异常数据、缺失数据进行提示,采集人员需及时核对修正,确保数据录入准确。 二、具体数据管理方法 1. 数据审核:设立专门质控人员,对CRF填写完整性、准确性进行人工审核,对EDC系统录入数据进行二次核查,重点核对关键指标、异常数据及逻辑矛盾数据,审核通过后标记为“已审核”,未通过的退回采集人员修正后重新审核。 2. 数据存储与备份:CRF统一编号后由专人保管,纸质CRF存放于专用档案柜,电子CRF及EDC系统数据采用加密存储,定期进行双重备份,防止数据丢失、篡改,确保数据安全性和可溯源性。 3. 数据修改与溯源:EDC系统中已录入数据如需修改,需由采集人员提交修改申请,说明修改原因,经质控人员审核批准后方可修改,系统自动记录修改时间、修改人员及修改前后内容,实现数据修改全程溯源;CRF数据如需修改,需在原始记录旁标注修改内容、修改时间及修改人员签字,严禁涂改、覆盖原始数据。 4. 数据归档:研究结束后,将所有CRF、EDC系统导出数据、审核记录、修改记录等整理归档,按照临床试验数据管理规范要求保存,确保数据可追溯、可核查,满足后续研究复盘及相关核查要求。

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

I. Specific Data Collection Methods 1. Requirements for Data Collectors: All researchers involved in data collection shall receive standardized training, proficiently master the specifications for completing Case Report Forms (CRFs), the operating procedures of the Electronic Data Capture (EDC) system, and various data collection standards. They shall clarify the collection time points, methods, and recording requirements for different indicators to avoid data deviations caused by non-standard operations. 2. CRF Collection Process: Standardized paper-based CRFs shall be adopted. After subject recruitment and before and after the initiation of the intervention, demographic data (gender, age, educational background, etc.) and baseline clinical characteristics shall be collected. 3. EDC Collection Process: Upon completion and approval of the CRFs, data collectors shall promptly enter the data into the EDC system. During data entry, strict comparison with the CRF contents shall be conducted to ensure consistency between the entered data and the original records. The system automatically performs real-time data validation and logical checks, prompting alerts for abnormal and missing data. Data collectors shall verify and correct such data in a timely manner to ensure accurate data entry. II. Specific Data Management Methods 1. Data Review: Dedicated quality control personnel shall be assigned to manually review the completeness and accuracy of completed CRFs and conduct a secondary verification of data entered into the EDC system, with a focus on key indicators, abnormal data, and logically inconsistent data. Approved data shall be marked as "Reviewed", while unapproved data shall be returned to data collectors for revision and subsequent re-review. 2. Data Storage and Backup: All CRFs shall be uniformly numbered and kept by designated personnel. Paper CRFs shall be stored in special filing cabinets, while electronic CRFs and EDC system data shall be stored in encrypted form. Dual backups shall be performed regularly to prevent data loss and tampering, ensuring data security and traceability. 3. Data Modification and Traceability: Any modification to data already entered into the EDC system requires data collectors to submit a modification application stating the reason for the change. Modifications may only be made upon review and approval by quality control personnel. The system automatically records the modification time, operator, and content before and after the change, realizing full traceability of data modifications. For revisions to CRF data, the modified content, time, and signature of the reviser shall be noted next to the original records. Alteration or overwriting of original data is strictly prohibited. 4. Data Archiving: Upon completion of the study, all CRFs, data exported from the EDC system, review records, modification records, and other documents shall be sorted and archived, and preserved in accordance with the specifications for clinical trial data management. This ensures data traceability and verifiability to meet requirements for subsequent study review and relevant inspections.
