研究目的:

咀嚼槟榔与口腔黏膜下纤维性变(Oral submucous fibrosis, OSF)等口腔疾病的发病密切相关,深入探究槟榔在健康个体中的早期生物效应,对于揭示其致病机制具有重要意义。近年来国内外研究多集中于槟榔碱等单一成分的生物学效应,对咀嚼槟榔的力学刺激及其他未知成分的影响知之甚少,对于槟榔作为复合刺激物所引发的宿主及微生物共代谢网络的全局性、动态性响应,目前仍缺乏清晰描绘。 本研究旨在通过以下设计探讨食品槟榔对健康人群的影响:招募曾有食品槟榔接触史但无咀嚼习惯的健康志愿者,在短期控制性咀嚼干预前后,于设定时间点全面监测其全身生理指标与口腔局部黏膜变化,并采集口腔样本进行微生物组、代谢组及炎症因子等多维度分析,系统揭示咀嚼行为对口腔微环境及全身生理状态的短期影响,从而丰富食品槟榔健康风险的临床证据,为相关危害防控提供科学依据,并为槟榔相关性口腔疾病的病因机制研究奠定理论基础。  

Objectives of Study:

Chewing areca nut is closely linked to oral diseases like oral submucous fibrosis (OSF). Studying its early biological effects in healthy individuals is crucial for understanding pathogenesis. Current research predominantly focuses on single components (e.g., arecoline), while the mechanical stimulation and complex compositional effects remain poorly characterized, leaving the systemic host-microbial metabolic response unclear. This study investigates edible areca nut’s impact on healthy volunteers with prior exposure but no chewing habit. Before and after short-term controlled chewing, systemic physiological and local mucosal changes are monitored at set intervals, with oral samples analyzed for microbiome, metabolome, and inflammatory markers, in order to clarify short-term effects on the oral microenvironment and systemic state, thereby contributing to clinical evidence on areca nut health risks and supporting prevention strategies and etiological research.

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:

本研究采用纸质病例记录表(CRF)与电子数据采集(EDC)系统相结合的方式进行数据管理。 (1)数据采集:所有观察指标将实时、完整记录于纸质CRF。CRF将严格依据研究方案设计,涵盖所有需采集的观察指标,包括:人口学信息、咀嚼干预记录、体征记录、口腔黏膜检查结果、样本采集情况以及任何不良事件记录;所有数据将由经培训的研究人员,在试验时实时、准确、完整地填写于纸质CRF上,任何数据修改均需采用划线更正并签名标注日期,保证记录可溯源;主要研究者对CRF数据的最终准确性负责; (2)电子化与管理:CRF数据将及时录入符合规范的EDC系统(网址:http://www.medresman.org.cn/uc/patient/patientlistforwizard.aspxproj=12262)进行数据的电子化录入与管理。在试验结束后3个工作日内,授权的研究员将CRF数据双人独立录入EDC系统,系统将进行逻辑核查,并通过质疑管理流程确保数据质量,研究结束后,在所有疑问解决、并经主要研究者审核批准后,进行最终数据库锁定,锁定后的数据将不可更改,用于统计分析;所有可识别受试者身份的信息(如姓名、身份证号、联系方式)将单独保密保存,不与研究分析数据关联,EDC系统中仅使用受试者唯一识别码(Subject ID)。

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

This study employs a combined approach of paper-based case report forms (CRFs) and an electronic data capture (EDC) system for data management. (1) Data Collection: All observational indicators will be recorded in real-time and in full on paper CRFs. The CRFs will strictly adhere to the study protocol design, covering all required observational indicators, including: demographic information, chewing intervention records, vital signs, oral mucosal examination results, sample collection status, and any adverse event records; All data will be accurately and completely entered in real-time onto paper CRFs by trained investigators during the trial. Any data modifications must be made using the strike-through correction method with signature and date annotation to ensure traceability of records. The principal investigator is responsible for the final accuracy of CRF data. (2) Electronic Data Management: CRF data will be promptly entered into a compliant EDC system (URL: http://www.medresman.org.cn/uc/patient/patientlistforwizard.aspxproj=12262) for electronic data capture and management. Within 3 business days after trial completion, authorized investigators will perform dual independent data entry into the EDC system. The system will conduct logical checks and utilize a query management process to ensure data quality. Upon study completion, after all queries are resolved and approved by the Principal Investigator, the database will be locked. Locked data cannot be modified and will be used for statistical analysis. All personally identifiable information (PII) such as names, ID numbers, and contact details will be stored separately and confidentially, unlinked from the research analysis data. The EDC system exclusively uses a unique subject identifier (Subject ID).
