研究目的:

本研究旨在评估激光预处理联合ALA-PDT治疗口腔黏膜白斑的有效性和安全性,对比其与传统PDT治疗在疗效、治疗次数、单位病损面积治疗时长、不良反应等方面的差异,为临床治疗提供新选择。同时通过动物模型进一步验证,通过激光预处理,能够使得ALA更容易渗透组织。  

Objectives of Study:

This study aims to evaluate the efficacy and safety of laser pretreatment combined with ALA-PDT in the treatment of oral mucosal leukoplakia, compare the differences between it and traditional PDT treatment in terms of efficacy, treatment frequency, treatment duration per unit lesion area, adverse reactions, etc., and provide a new option for clinical treatment. At the same time, it was further verified through animal models that laser pretreatment can make ALA more easily penetrate tissues.

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:

每位就诊患者均建电子病历在我院存档,便于随时调取。 研究相关数据采取纸质版及六元空间电子版同时录入的方法。研究者根据受试者的原始观察记录,将数据及时、完整、正确、清晰地载入原始数据。录入采用相应的数据库系统双人双机录入。 原始数据在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等,以备查考。

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

Each patient seeking medical treatment will have an electronic medical record archived in our hospital for easy access at any time. The relevant research data was entered simultaneously in both paper and electronic versions of Liuyuan Space. Based on the original observation records of the subjects, the researchers promptly, completely, accurately and clearly loaded the data into the original data. Input is carried out using the corresponding database system with two people and two machines. After the original data is entered and verified as required, it is archived and saved in the order of their numbers, and a search directory and other information are filled in for future reference.
