研究目的:

本研究旨在阐明 IBS-D_A/D 患者的类淋巴功能,并通过结合 FMT 治疗,探索脑功能及类淋巴功能治疗前后变化与临床指标的相关性,为疾病检测治疗提供新的思路。  

Objectives of Study:

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:

1.数据采集: 通过提取入组受试者常规临床诊疗记录获取这项研究的数据。要求研究者在整个监测期间根据原始病历记录中的信息输入到研究的电子病例报告表(eCRF)和或记录表。数据采集内容: (1)记录人口统计学数据:出生日期、性别、姓名缩写、ID 号; (2)病史(包括既往病史); (3)其它的实验室检查类,如粪便、血清学检查; (4)颅脑磁共振影像学资料。 2.数据管理: (1)研究者必需保证数据真实、完整、准确; (2)研究记录做任何更正时只能划线,旁注改后的数据,说明理由,由研究者签名并注明日期,不得擦涂、覆盖原记录; (3)实验室检查项目齐全。

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

1. Data collection: The data of this study were obtained by extracting the routine clinical diagnosis and treatment records of the subjects in the group. Researchers are required to enter the electronic case report form (eCRF) and/or record sheet of the study according to the information in the original medical record during the entire monitoring period. Data collection content: (1) Record demographic data: date of birth, gender, abbreviation, ID number; (2) Medical history (including past medical history) ; (3) Other laboratory examinations, such as feces, serological examinations ; (4) Cranial magnetic resonance imaging data 2. Data management: (1) Researchers must ensure that the data is true, complete and accurate; (2) The research record can only be underlined when any correction, and the revised data can be noted to explain. The reason is that the researcher shall sign and indicate the date, and shall not erase or cover the original record; (3) The laboratory inspection items are complete.
