研究目的:

(1)亚叶酸干预 ASD 的剂量-效应规律及遗传背景的修饰效应 本研究拟明确亚叶酸改善 ASD 核心症状是否存在显著的剂量依赖性,并确定在综合康复背景下的临床有效剂量与安全阈值。在此基础上,深入解析以MTHFR为核心的遗传多态性如何修饰亚叶酸干预剂量效应,揭示不同基因型患儿是否存在差异化的剂量门槛,从而解决临床干预中疗效异质性显著的难题。 (2)甲基化循环在亚叶酸干预ASD中的分子机制 研究旨在解决甲基化循环异常与ASD发病的核心关联问题,阐明其在ASD发病中的作用路径。同时,明确亚叶酸如何通过调节甲基化循环代谢发挥ASD干预效应,揭示甲基化循环介导亚叶酸干预ASD的分子机制。  

Objectives of Study:

(1) Dose-response Relationship of Leucovorin Calcium Intervention in ASD and the Modifying Effect of Genetic Background This study aims to determine whether leucovorin calcium improves the core symptoms of autism spectrum disorder (ASD) in a significant dose-dependent manner, and to identify the clinically effective dose and safety threshold under comprehensive rehabilitation. On this basis, we will further analyze how genetic polymorphisms centered on MTHFR modify the dose-response effect of leucovorin calcium intervention, and explore whether children with different genotypes exhibit differential dose thresholds, so as to address the marked heterogeneity of treatment efficacy in clinical intervention. (2) Molecular Mechanism of the Methylation Cycle in Leucovorin Calcium Intervention for ASD This study intends to clarify the core association between abnormal methylation cycle and ASD pathogenesis, and elucidate its functional pathway in the development of ASD. Meanwhile, it will reveal how leucovorin calcium exerts its therapeutic effect on ASD by regulating the metabolism of the methylation cycle, and uncover the molecular mechanism by which the methylation cycle mediates the intervention effect of leucovorin calcium on ASD.

药物成份或治疗方案详述:

本研究所用的亚叶酸钙片由广东岭南制药有限公司生产并提供(国药准字H20040396),药品为黄白色或类白色片剂。模拟剂亦由该公司制作,除不含亚叶酸外,其辅料成分、形态、颜色及片重等均与干预药物保持一致。

The drug is presented as yellowish-white or off-white tablets.The placebo was also produced by the same company. It is identical to the investigational product in excipient composition, appearance, color, tablet weight and other characteristics, with the only exception that it contains no leucovorin calcium.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用分层区组随机化方法生成随机分配序列,以确保各试验组基线特征均衡可比。以研究中心为主要分层因素,因多中心研究中不同中心的诊疗流程、受试者基线特征可能存在差异,按中心分层可减少中心效应对试验结果的影响。年龄、ASD严重程度为次要分层因素。采用多中心统一编号体系:编号前两位代表不同研究单位中间三位为受试者的个体识别码;最后两位为随访时点标识。由独立于研究执行团队的统计人员完成,使用统计软件生成随机序列。采用变动区组长度,以防止临床人员预测分组。随机序列生成后,按中心进行分配,确保每个分层内4组受试者的例数比例一致。

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

"This study employed a stratified block randomization method to generate the randomization sequence, ensuring that baseline characteristics were balanced and comparable across the trial groups. The study site was selected as the primary stratification factor. Given that diagnostic and treatment protocols, as well as subject baseline characteristics, may vary across sites in a multicenter study, stratifying by site mitigates the impact of center effects on trial outcomes. Age and ASD severity served as secondary stratification factors. A unified multicenter numbering system was implemented: the first two digits denote the research site, the middle three digits serve as the subject's unique identification code, and the final two digits indicate the follow-up time point. The randomization sequence was generated using statistical software by an independent statistician who was not part of the research execution team. Variable block sizes were utilized to prevent clinical staff from predicting group assignments. Following its generation, the randomization sequence was allocated by site, ensuring a consistent ratio of subjects across the four groups within each stratum.

盲法:

本研究采用双盲设计,施盲对象包括受试者及其监护人、医护提供者(含康复治疗师、随访人员)、结局评估者及数据分析者,所有设盲对象在研究全程均无法获知受试者的分组信息。

Blinding:

This study adopted a double-blind design. The blinding subjects included participants and their guardians, healthcare providers (including rehabilitation therapists and follow-up staff), outcome assessors, and data analysts. All blinded individuals were not informed of the participants' group assignment throughout the entire study period.

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:

本研究采用统一设计的病例报告表(CRF)采集数据,由经培训的研究人员规范填写,确保数据真实、准确、完整;同时采用 Excel 建立电子数据库,实行双人双录入以控制录入误差,并设置权限管理保障数据安全。分中心每周核查 CRF,牵头中心定期开展现场质控,重点核查数据完整性与逻辑性;原始纸质资料各中心存档不少于研究结束后 5 年,电子数据库加密备份。项目实施前对研究人员统一培训,质控组每月抽查病例,确保评估方法一致与数据质量。

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

In this study, a uniformly designed Case Report Form (CRF) was used for data collection, filled by trained researchers to ensure data authenticity, accuracy and completeness. An electronic database was established with Excel, adopting double data entry to reduce input errors, and access permissions were set for data security. Each sub-center reviewed CRFs weekly, and the leading center conducted on-site quality control to verify data integrity and logic. Original paper documents were archived for at least 5 years after study completion, and the electronic database was encrypted and backed up regularly. All researchers received unified training before the study, and the quality control team reviewed 30% of cases monthly to ensure consistent assessment methods and data quality.
