研究目的:

本次研究通过一个随机、双盲、安慰剂对照的临床试验,重点研究益气解毒代表药物感毒清对成都地铁PM2.5高暴露人群呼吸系统损伤的安全性和有效性,并通过“Th1/Th2平衡漂移”路径评价感毒清的潜在作用机制和获益风险。研究有望从“Th1/Th2平衡漂移”介导免疫-炎症损伤角度深入阐释益气解毒法防治PM2.5诱导慢性气道炎症的科学内涵,为感毒清的临床运用提供新的证据,为地铁PM2.5高暴露所致呼吸系统损伤提供潜在的中医药防治方法。

Objectives of Study:

In this study we focused on the safety and efficacy of Ganduqing a representative drug of Yiqi Jiedu on respiratory system injury in people with high PM2.5 exposure in Chengdu Metro through a randomized double-blind placebo-controlled clinical trial and evaluated the potential mechanism of action and benefit risk of Ganduqing through the "Th1/Th2 balance drift" pathway. The study is expected to deeply explain the scientific connotation of invigorating qi and detoxicating method in preventing and treating PM2.5-induced chronic airway inflammation from the perspective of "Th1/Th2 balance drift" mediated immune-inflammatory injury provide new evidence for the clinical application of Ganduqing and provide potential TCM prevention and treatment methods for respiratory system injury caused by high exposure to PM2.5 in the subway.

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:

数据的收集和监测由专门的数据委员会管理。数据委员会由一名统计师、一名呼吸科副主任医师和一名初级中医师组成,在试验开始前成立。数据委员会可以自由调查所有参试者的资料,与试验组其他成员之前无竞争利益。项目组成员通过CRF表格记录受试者的原始数据,包括简要病历、基本信息、治疗记录、治疗前后评估数据和随访数据、不良事件记录等。未经数据委员会授权或同意,任何人不得对纸质版原始数据进行更改。另外两名数据录入者将负责将数据输入ResMan管理平台的系统中。

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

Data collection and monitoring were managed by a dedicated data committee. The Data Committee consisted of a statistician an associate respiratory chief physician and a junior herbalist and was established before the start of the trial. The Data Committee was free to investigate all participants' information and had no prior competing interests with other members of the trial group. Project team members record the original data of subjects through CRF including brief medical records basic information treatment records evaluation data before and after treatment and follow-up data and adverse event records. No changes to the paper raw data will be made without authorization or consent of the Data Committee. The other two data entry providers will be responsible for entering the data into the system of the ResMan management platform.
