干预措施:

实施3个周期的模拟禁食饮食(FMD)方案,每月连续5天执行,其余时间保持常规清淡饮食(避免辛辣、油腻、生冷刺激性食物)。FMD方案由天津医科大学总医院营养科医师量身定制,为植物性低热量饮食,严格控制每日热量摄入,以杂粮、蔬菜、低糖水果、植物性油脂为主,避免动物蛋白、精制糖、精加工食品;餐食可由患者自行按方案制作,也可选择医院统一配送,研究医师及营养科医师定期指导饮食执行情况。

干预措施代码:

Intervention:

Three cycles of a fasting-mimicking diet (FMD) regimen will be implemented, with 5 consecutive days of FMD per month, and a regular light diet (avoiding spicy, greasy, raw/cold and other irritating foods) during the remaining days. The FMD regimen is tailored by dietitians from the Department of Nutrition, General Hospital of Tianjin Medical University. It is a plant-based, low-calorie diet with strict control of daily calorie intake. The diet is mainly composed of whole grains, vegetables, low-sugar fruits, and vegetable oils, while animal proteins, refined sugars, and highly processed foods are prohibited. Patients may prepare meals by themselves according to the regimen or choose unified meal delivery from the hospital. The attending researchers and dietitians will regularly supervise and provide guidance on diet adherence.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用简单随机化方法生成随机序列,由天津医科大学总医院消化内科非研究执行人员的统计师,使用SPSS 26.0统计软件的随机数字表功能,按1:1分配比例生成试验组与对照组的随机分配序列,随机序列生成后进行密封保存,研究入组时由独立研究人员按入组顺序依次调取分组结果

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

In this study, a simple randomization method was employed to generate a random sequence. The statistician from the non-executive staff of the Department of Gastroenterology at Tianjin Medical University General Hospital used the random number table function of SPSS 26.0 statistical software to generate the random allocation sequence for the experimental group and the control group in a 1:1 ratio. After the random sequence was generated, it was sealed and stored. At the time of study enrollment, independent researchers retrieved the grouping results in the order of enrollment.

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:

病例记录表(CRF):根据研究方案设计定制化纸质 / 电子 CRF 表,涵盖研究对象基线资料(年龄、病程、BMI 等)、入组筛选结果、随机分组信息、饮食干预执行情况、随访记录、临床疗效指标(改良 Mayo 评分、内镜下表现等)、实验室检测结果(血常规、炎症指标、肠道菌群等)、安全性指标及不良反应记录等全部研究数据,由经培训的研究人员按统一规范实时、准确填写,做到字迹清晰、数据完整、无漏项错项。 电子数据采集和管理系统(EDC):采用ResMan 电子数据采集系统(基于互联网的专业 EDC 平台)作为核心数据管理工具,将纸质 CRF 表信息同步录入 ResMan 系统,实现数据的电子化存储、实时核查与溯源。系统设置数据录入权限管理,仅授权研究人员可操作;建立数据双录与交叉核对机制,由两名独立研究人员分别录入同一批数据,系统自动比对差异并人工核实修正;设置逻辑校验规则,对异常数据(如数值超出合理范围、前后数据矛盾等)进行自动预警,确保数据的准确性、完整性和一致性。

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

Case Record Form (CRF) : Customized paper/electronic CRF forms were designed in accordance with the study protocol, covering all research data including subjects' baseline information (age, disease course, BMI, etc.), enrollment screening results, randomization assignment information, dietary intervention adherence, follow-up records, clinical efficacy indicators (modified Mayo score, endoscopic findings, etc.), laboratory test results (complete blood count, inflammatory markers, gut microbiota, etc.), as well as safety indicators and adverse reaction records. All forms were filled out in real time and accurately by trained researchers in compliance with unified specifications, ensuring legible writing, complete data, and no missing or incorrect entries. Electronic Data Capture (EDC) System : The ResMan Electronic Data Capture System, a professional internet-based EDC platform, was adopted as the core data management tool. Data from paper CRF forms were synchronously entered into the ResMan System to realize electronic data storage, real-time verification and traceability. The system was equipped with data entry permission management, with operations restricted to authorized researchers only. A dual data entry and cross-check mechanism was established, where two independent researchers entered the same batch of data separately; the system automatically identified discrepancies, which were then verified and corrected manually. Logical validation rules were set to trigger automatic alerts for abnormal data (e.g., values outside the reasonable range, contradictory data across different time points), so as to ensure the accuracy, completeness and consistency of the research data.
