研究目的:

职业性慢性金属中毒导致的慢性周围神经病,已成为严重影响劳动者身体健康和生活质量的主要职业中毒后遗症之一,临床救治困难。大量研究证实了中药熏洗、针灸、推拿、穴位注射等中医外治疗法在温经通络、活血化瘀、益气养血等方面作用,具有“直达病所”、“内病外治”的优势和在周围神经病变康复中的价值。本研究拟将温经足浴方、益气活血汤、微针针刺/揿针、穴位贴敷、穴位注射等多种外治技术进行有机整合,开展多中心随机对照试验,通过临床症状体征改善率等指标分析其有效性。希望通过该试验为重金属中毒后遗症提供有效、安全、易于推广的中医康复方案。  

Objectives of Study:

Chronic peripheral neuropathy caused by occupational chronic metal poisoning has become one of the major sequelae of occupational poisoning that severely affects the health and quality of life of workers, with clinical treatment being challenging. Extensive research has confirmed the efficacy of traditional Chinese medicine (TCM) external therapies such as fumigation and washing, acupuncture, tuina, and acupoint injection in warming the meridians, promoting blood circulation, resolving stasis, and replenishing qi and blood. These therapies demonstrate advantages of "directly targeting the disease site" and "external treatment for internal diseases," as well as their value in the rehabilitation of peripheral neuropathy. This study aims to integrate various external treatment techniques, including warming meridian foot baths, Qi-replenishing and blood-activating decoctions, micro-needling/pressing, acupoint application, and acupoint injection, into a multicenter randomized controlled trial. The effectiveness will be evaluated through indicators such as the improvement rate of clinical symptoms and signs. It is hoped that this trial will provide an effective, safe, and easily replicable TCM rehabilitation protocol for the sequelae of heavy metal poisoning.

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:

1.数据收集和管理 数据管理将遵循标准化操作过程,按照CRF的格式建立数据库,并设立检查程序,录入时遇到的问题由录入员进行记录,对存疑的数据由数据管理员汇总后向研究单位发出疑问表。 2.数据的录入与修改 使用EDC系统进行原始数据的录入和管理。各参与中心会获得独立的用户名和密码,研究中心指定人员通过安全网络将原始数据录入CRF表,允许研究中心人员对录入的数据进行修改。在数据库锁定之前,研究者可以修改录入的数据,但是所有修改必须留存修改痕迹并可以追溯。 3.原始数据核查 质控员确认CRF 中的所有数据与原始记录一致。如有错误或遗漏,则将以电子质疑表的形式向研究中心人员发出质疑,要求对 CRF 中的数据进行澄清或修改。 4.数据核查 数据管理单位按照标准操作流程,对记录在 CRF 中的数据进行审核(人工核查)。对于数据中出现的疑问,数据管理人员将以电子质疑表的形式向研究中心人员发出质疑,要求研究中心指定的人员对质疑进行答复,并对数据做出一些必要的修改。所有的数据更改及相关的操作,都需要有留痕记录。 5.数据库锁定 数据管理员依据试验方案、数据审核标准及数据库撰写盲态数据审核报告。由临床研究织申办方、主要研究者、统计人员及数据管理人员参加盲态数据审核会议,对数据进行审核,由参会各方代表签署审核决议 6.质量控制 研究者资格:申办方将对参加临床试验的研究者必须经过资格审查,确保其具备进行临 床试验的专业背景及能力; 研究人员培训:在临床试验开始前,通过医学伦理委员会审批后,由申办方及监察员召集所有参加试验的研究者展开启动前培训,布置和讨论方案,统一认识,落实入选和排除标 准、不良事件处理、病例报告表和严重不良事件表的填写等内容; 研究的管理:主要研究者和监察员定期对数据的准确性进行内部审核,审查注册率,核实研究数据,监督和协调整个研究。通过上述措施可以发现方案执行中存在的偏差,并及时向其他共同研究者反馈。

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

1. Data collection and management Data management will adhere to standardized operational procedures, establish databases in accordance with CRF formats, and implement inspection protocols. Issues encountered during data entry shall be documented by the entry staff. Doubtful data shall be consolidated by the data administrator and subsequently submitted to the research institution via a query form. 2. Data Entry and Modification The EDC system is utilized for raw data entry and management. Participating centers are assigned unique usernames and passwords. Designated personnel from research centers input raw data into CRF forms via secure networks, with permission to modify the data. Researchers may make edits to the entered data before database locking, but all modifications must retain traceable modification records for auditability. 3. Raw data verification The quality control officer verifies that all data in the CRF is consistent with the original records. In case of errors or omissions, a question form will be issued to the research center personnel in electronic format, requesting clarification or modification of the data in the CRF. 4. Data Verification The data management unit conducts manual review of data recorded in CRFs in accordance with standard operating procedures. For any discrepancies identified in the data, data managers will submit electronic query forms to research center personnel, requesting responses from designated personnel at the research center and necessary data modifications. All data changes and related operations must be documented with traceable records. 5. Database Locking The data administrator prepares the blinded data review report based on the trial protocol, data review criteria, and the database. The blinded data review meeting is attended by representatives from the clinical study sponsor, principal investigators, statisticians, and data management personnel to conduct data review, with all participants signing the review resolution. 6. Quality Control Investigator Qualifications: The sponsor will conduct qualification reviews for investigators participating in clinical trials to ensure they possess the professional background and capabilities required for conducting clinical trials. Researcher Training: Prior to the initiation of clinical trials, following approval by the Medical Ethics Committee, the sponsor and monitors convene all participating investigators for pre-start training. This session involves outlining and discussing the protocol, aligning perspectives, and implementing inclusion/exclusion criteria, adverse event management protocols, as well as the completion of case report forms and serious adverse event forms. Study Management: The principal investigator and monitors conduct regular internal audits on data accuracy, review registration rates, verify study data, and oversee and coordinate the entire study. These measures enable the identification of deviations in protocol implementation and prompt feedback to other co-investigators.
