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:

皮肤组织RNA测序结果由华大基因进行数据录入与分析。 血液样本得流式细胞学结果、血液样本及皮肤组织样本得qPCR结果由本人在实验室仪器完成后,导出数据,分别用FlowJo_V10以及Excel进行数据分析后,导出至SPSS 25并进行后续分析。 免疫组织化学结果由inform软件进行分析。 在仔细核查知情同意与入选/排除标准检查后采集瘢痕疙瘩患者及健康人得相应部位皮肤组织以及血液,并建立数据采集表(登记志愿者基本信息、样本采集情况与日期)。后续所有数据获取后,在经过初步核查后登记至数据采集表。在所有数据采集完毕后,由组中其他成员对所有数据的完整性检查、逻辑一致性检查、离群数据检查、时间窗检查、不良事件检查再次检查并登记至数据采集表。 按要求完成数据录入与核查后,按编号顺序归档保存并设置检索目录。数据文件包括数据库、检查程序、分析程序、分析结果、编码本和说明文件等,分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。所有原始档案按相应规定内的期限保存

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

Data entry and analysis of skin RNA sequencing results were performed by BGI. The flow cytometry results of blood samples and qPCR results of blood samples and skin tissue samples were obtained by myself in the laboratory instrument, and the data were exported to SPSS 25 for subsequent analysis after data analysis with FlowJo_V10 and Excel. Immunohistochemical results were analyzed by INFORM software. After carefully checking the informed consent and inclusion/exclusion criteria, skin tissue and blood from keloid patients and healthy people were collected, and a data collection form (basic information of registered volunteers, sample collection situation and date) was established. All subsequent data acquisition shall be registered in the data collection form after preliminary verification. After all data were collected, the other members of the group checked the integrity, logical consistency, outlier data, time window and adverse event of all data again and registered them in the data collection table. After completing data entry and verification as required, file and save the data in serial order and set the retrieval directory. Data files include databases, inspection programs, analysis programs, analysis results, code books and description files, etc., which are stored in different categories, and multiple backups are stored on different disks or recording media, which are properly stored to prevent damage. All original files shall be maintained for the period specified accordingly.
