研究目的: |
本研究拟纳入抑郁症患者及健康对照人群,基于脑电(EEG)、磁共振成像(MRI)、心率变异性(HRV)和功能性近红外光谱技术(fNIRS)等神经影像与电生理技术,系统揭示抑郁症前额叶-海马环路异常脑网络的特征及其潜在病理机制,筛选可用于精准诊疗的神经影像学标志物。在此基础上,本研究旨在评估间歇性θ节律经颅磁刺激(intermittent theta burst stimulation,iTBS)在抑郁症患者中的临床疗效及安全性,通过对患者接受iTBS治疗前后抑郁症状变化的系统评估,明确其在改善情绪症状方面的有效性。同时,结合神经信号指标的动态变化,探讨iTBS对脑功能活动及自主神经调节的影响,进一步分析神经生物学变化与临床疗效之间的关系,筛选与治疗反应相关的潜在生物标志物,并评估基线神经影像及电生理特征对治疗反应的预测价值,从而为抑郁症的病理机制研究及个体化精准治疗提供科学依据。 |

Objectives of Study: |
This study aims to recruit patients with depression and healthy controls. By using neuroimaging and electrophysiological techniques such as electroencephalography (EEG), magnetic resonance imaging (MRI), heart rate variability (HRV), and functional near-infrared spectroscopy (fNIRS), we will systematically characterize the aberrant brain network features of the prefrontal-hippocampal circuit in depression and their underlying pathological mechanisms, and identify neuroimaging biomarkers for precision diagnosis and treatment. On this basis, this study seeks to evaluate the clinical efficacy and safety of intermittent theta burst stimulation (iTBS) in patients with depression. Through systematic assessment of depressive symptom changes before and after iTBS treatment, the effectiveness of iTBS in improving mood symptoms will be determined. Meanwhile, by tracking dynamic changes in neural signal indicators, the effects of iTBS on brain functional activity and autonomic nervous regulation will be explored, further analyzing the relationship between neurobiological changes and clinical efficacy. Potential biomarkers associated with treatment response will be screened, and the predictive value of baseline neuroimaging and electrophysiological features for treatment response will be assessed, thereby providing a scientific basis for research on the pathological mechanisms of depression and individualized precision treatment. |

盲法: |
本研究横断面阶段为非随机非盲法设计。干预阶段的两项研究(iTBS前瞻性实验和闭环TBS干预)均为随机、双盲、对照设计,参与者分别按1:1和1:1:1比例随机分配至不同治疗组,双盲,即受试者与结局评估者均对分组情况不知情,贯穿整个干预与评估过程。干预阶段,伪刺激组使用具备磁屏蔽功能的假线圈。 |
|
Blinding: |
This study employed a non-randomized, non-blinded design in the cross-sectional phase. In the intervention phase, both studies (the iTBS prospective experiment and the closed-loop TBS intervention) adopted a randomized, double-blind, controlled design, in which participants were randomly assigned to different treatment groups in a 1:1 ratio and a 1:1:1 ratio, respectively. The double-blind procedure, meaning that both the participants and the outcome assessors were unaware of the group assignments, was maintained throughout the entire intervention and assessment process. During the intervention phase, the sham stimulation group received a sham coil equipped with magnetic shielding functionality. |

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、数据采集 纸质CRF与电子CRF并行:所有研究数据由经过统一培训的研究人员按照标准操作流程(SOP)进行采集。研究者根据受试者原始观察记录,将数据及时、完整、准确、清晰地记录于纸质病例报告表(CRF),同时或同步录入电子病例报告表(eCRF)(基于EDC系统)。 二、量表与检查数据的采集: 临床量表:由经过一致性培训的评估人员完成,结果直接记录于CRF及EDC系统。 神经影像与电生理检查:检查由专业技术人员在统一设备及标准参数条件下实施,原始数据及分析结果上传至电子管理系统或独立存储,以减少测量误差和系统偏倚。 三、数据录入与核查 双人独立录入与核对:采用双人独立录入机制,确保数据准确性。纸质CRF经监查员审核并签字后,由数据管理员进行双录入(将两份独立录入的数据进行一致性比对)。EDC系统可支持远程数据录入与实时逻辑核查。 数据库全面检查:数据管理员在完成双录入及一致性核查后,对数据库进行全面检查,并出具数据库检查报告,内容包括:研究完成情况(含脱落病例);入排标准符合性;数据完整性;逻辑一致性;离群值检测;时间窗合理性;合并用药情况;不良事件记录。 四、数据审核与数据库锁定 数据审核会议:由主要研究者、申办方代表(如适用)、监查员、数据管理员及统计人员共同参与,对知情同意书签署情况及数据库检查报告中提出的问题进行审核与决议,形成审核报告。 数据库锁定:经审核确认无误后,对数据库进行锁定。锁定后数据不得随意更改,确保统计分析的规范性与数据的严肃性。 五、数据存储与档案管理 纸质资料归档:所有纸质CRF、知情同意书及相关原始资料按编号顺序归档保存,并建立检索目录以便追溯。 电子数据存储:电子数据文件(包括数据库、数据检查程序、统计分析程序、分析结果及编码文件等)分类存储,并进行多重备份,分别保存于不同存储介质或服务器中,以防止数据丢失或损坏。 保存期限:所有研究资料按照相关法规要求保存至规定年限。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
I. Data Collection Parallel Paper and Electronic CRFs: All study data will be collected by uniformly trained researchers following Standard Operating Procedures (SOPs). Based on the participants' original observation records, the researchers will record the data promptly, completely, accurately, and clearly on the paper Case Report Form (CRF) and simultaneously or synchronously enter it into the electronic Case Report Form (eCRF) (based on the EDC system). II. Collection of Scale and Examination Data Clinical Scales: Will be completed by assessors who have undergone consistency training, with results recorded directly on the CRF and into the EDC system. Neuroimaging and Electrophysiological Examinations: Will be performed by professional technicians using standardized equipment and under standard parameter conditions. The raw data and analysis results will be uploaded to the electronic management system or stored independently to reduce measurement error and systematic bias. III. Data Entry and Verification Dual Independent Entry and Verification: A dual, independent data entry mechanism will be used to ensure data accuracy. After the paper CRF has been reviewed and signed by the monitor, the data administrator will perform dual data entry (comparing the consistency of the two independently entered datasets). The EDC system can support remote data entry and real-time logical checks. Comprehensive Database Check: After completing the dual entry and consistency checks, the data administrator will perform a comprehensive check of the database and issue a database check report. The report will include: study completion status (including dropouts); compliance with inclusion/exclusion criteria; data completeness; logical consistency; outlier detection; visit window compliance; concomitant medication use; and adverse event records. IV. Data Review and Database Lock Data Review Meeting: A data review meeting will be convened, attended by the principal investigator, sponsor representative (if applicable), monitor, data administrator, and statistician. The meeting will review and make decisions on the signed informed consent forms and issues raised in the database check report, and will generate a review report. Database Lock: Once confirmed to be correct after the review, the database will be locked. No data can be changed arbitrarily after the lock, ensuring the standardization of the statistical analysis and the integrity of the data. V. Data Storage and Archiving Paper Document Archiving: All paper CRFs, informed consent forms, and related source documents will be archived and preserved in numerical order, and a searchable catalog will be established for traceability. Electronic Data Storage: Electronic data files (including the database, data verification programs, statistical analysis programs, analysis results, and coding files) will be stored by category and backed up in multiple copies on different storage media or servers to prevent data loss or damage. Retention Period: All study materials will be preserved for the period required by relevant regulations. |
