研究设计:

横断面 

Study design:

Cross-sectional 

研究目的:

① 通过单中心横断面现况研究,系统对比DED患者与健康人群血清、尿液、粪便样本,运用肠道菌群分析、尿液菌群分析及血清非靶代谢组学技术,全面分析微生物群落、代谢物等层面差异,筛选出具有显著区分性的生物标志物。 ② 深入探究筛选出的生物标志物在DED发病机制中的作用,明确其与疾病发生、发展的关联,为解析DED病理机制提供关键线索。  

Objectives of Study:

①Through a single-center cross-sectional status study, the serum, urine and fecal samples of DED patients and healthy individuals were systematically compared. Using intestinal flora analysis, urine flora analysis and serum non-target metabolomics techniques, the differences at the microbial community, metabolites and other levels were comprehensively analyzed to screen out biomarkers with significant discrimination. ② Deeply explore the role of the screened biomarkers in the pathogenesis of DED, clarify their association with the occurrence and development of the disease, and provide key clues for analyzing the pathological mechanism of DED.

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:

数据采集流程:研究数据包含临床信息、生物样本数据和检测数据三类。临床信息通过纸质问卷收集,涵盖参与者基本信息、糖尿病病史等内容,由研究者核对确保准确;生物样本数据包括血清、粪便和尿液,其中血清由专业医护人员采集,粪便和尿液在研究者指导下由参与者自采,所有样本采集后按规定温度和时间要求进行处理和保存;检测数据则是将生物样本送至具备资质的实验室,通过 16S rRNA 测序和 UPLC-MS 分析获取。为保证采集规范,研究制定了统一的操作标准流程(SOP),要求所有研究者培训考核通过后上岗,并对样本进行质量检查,如出现溶血样本需重新采集。 数据管理体系:在数据存储方面,纸质文件存放于带锁文件柜,仅限授权人员接触;电子数据加密存储于医院专用服务器,并每日备份至异地云端。数据安全上,采用哈希算法对可识别个人信息进行匿名化处理,生物样本标签仅标注研究编号,数据传输全程加密。权限管理实行分级制度,主研人拥有数据查看、导出和分析权限,修改需审批;研究助理仅可录入和初步整理数据;第三方合作方只能获取脱敏后的汇总数据,且需签署保密协议。数据使用遵循内部仅限本研究团队科研分析、外部共享需获参与者书面同意且符合法规要求的原则。

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

Data collection process: Research data includes three categories: clinical information, biological sample data, and test data. Clinical information was collected through paper questionnaires, covering basic information of participants, history of diabetes, etc., and was checked by researchers to ensure accuracy. Biological sample data include serum, feces and urine. Among them, serum was collected by professional medical staff, while feces and urine were self-collected by participants under the guidance of researchers. All samples were processed and preserved in accordance with the prescribed temperature and time requirements after collection. The detection data were obtained by sending biological samples to qualified laboratories and conducting 16S rRNA sequencing and UPLC-MS analysis. To ensure the collection norms, a unified standard operating procedure (SOP) was studied and formulated. All researchers were required to pass the training and assessment before taking up their posts, and the quality of the samples was inspected. If hemolysis samples were found, they needed to be re-collected. Data management system: In terms of data storage, paper documents are stored in locked filing cabinets and are accessible only to authorized personnel. Electronic data is encrypted and stored on a hospital-specific server, and is backed up to a remote cloud every day. In terms of data security, hash algorithms are adopted to anonymize identifiable personal information. Biological sample labels are only marked with research numbers, and the entire data transmission process is encrypted. The permission management implements a hierarchical system. The main researcher has the permissions to view, export and analyze data, and any modifications require approval. The research assistant can only enter and initially organize the data. Third-party partners can only obtain the desensitized aggregated data and must sign a confidentiality agreement. The use of data adheres to the principle that it is internally limited to the scientific research analysis of this research team only, and external sharing requires the written consent of the participants and compliance with regulatory requirements.
