研究目的:

本研究拟以糖尿病神经血管耦合损伤这一重要病理机制为切入点,以眼脑多模态影像技术为手段,与中医证候研究进行深入的融合交叉研究,建立基于眼脑影像评价技术体系的糖尿病神经血管耦合损伤病证诊疗标准,为疾病早期诊断及疗效评价提供客观量化的依据。同时,开展多中心、大样本、随机双盲临床试验,系统研究糖神安颗粒防治糖尿病神经血管耦合损伤的临床疗效及安全性,获得高质量中医药循证证据,提高中医药防治水平和临床服务能力,为中药新药研发及成果转化提供新的思路和方向。

Objectives of Study:

This study intends to take the critical pathological mechanism of diabetic neurovascular coupling injury as the starting point and utilize multi-modal imaging technology of the eyes and brain as a means to conduct in-depth integrated and interdisciplinary research with Traditional Chinese Medicine (TCM) syndrome studies. The aim is to establish diagnostic and therapeutic standards for diabetic neurovascular coupling injury based on the ocular-cerebral imaging evaluation technology system providing objective and quantitative evidence for early disease diagnosis and therapeutic effect evaluation. Simultaneously we will conduct multicenter large-sample randomized double-blind clinical trials to systematically investigate the clinical efficacy and safety of Tangshen'an Granule in preventing and treating diabetic neurovascular coupling injury. By obtaining high-quality evidence-based data on traditional Chinese medicine we aim to enhance the level of prevention and treatment with traditional Chinese medicine and clinical service capabilities thereby providing new ideas and directions for the research a

随机方法(请说明由何人用什么方法产生随机序列):

随机化方法对受试者进行分组,试验组和对照组比例为1:1。随机序列由不参与试验具体实施过程的统计学人员采用SAS9.4软件根据给定的种子和合适的区组长度生成。

Randomization Procedure (please state who generates the random number sequence and by what method):

Participants are randomized into a trial group and a control group in a 1:1 ratio. The randomization sequence is generated by statistical personnel who are not involved in the actual implementation of the trial using SAS9.4 software based on a given seed and an appropriate block size.

盲法:

委托第三方公司生产试验药和安慰剂,保证两者有统一的标签格式以及外包装,并由不参与试验实施过程的药剂师根据上述随机序列对药品进行编盲。研究者按分配的药物编号依患者入组的先后顺序对号使用。

Blinding:

The production of the experimental drug and placebo is entrusted to a third-party company ensuring that both are provided with a unified label format and outer packaging. The blinding of the medications is conducted by pharmacists who do not participate in the trial implementation process based on the aforementioned randomization sequence which was generated using SAS9.4 software by statistical personnel. The researchers use the medications according to the assigned drug numbers in the order of patients' enrollment.

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 本研究采用纸质病例报告表(CRF)收集数据。研究者应按照研究方案要求完整、真实地填写CRF。原始化验单保留齐全,CRF表中记录的实验室检查数据或描述要与原始检验报告核对无误。 (2)数据管理过程 本研究的数据管理工作委托成都中医药大学附属医院基地办公室、循证医学中心完成。 数据管理员按照研究方案要求,在接收到CRF后进行人工检查,发现无法解决的数据问题时向研究者发出疑问表,请研究者对问题数据做出解答。 人工检查后,采用EpiData software V3.1进行数据录入、逻辑检查和数据校对,确保数据库数据与源文档的一致性。 在完成数据录入并更正问题数据后,按照统计分析计划的要求进行盲态审核和数据库锁定。

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

(1) Data Collection For this study paper-based Case Report Forms (CRFs) are utilized for data collection. Researchers should complete the CRFs accurately and truthfully in accordance with the requirements of the research protocol. Original laboratory test reports must be kept intact and the laboratory test data or descriptions recorded in the CRF should be verified against the original test reports for accuracy. (2) Data Management Process The data management tasks for this study are entrusted to the Base Office and the Evidence-Based Medicine Center of the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine. The data manager in accordance with the research protocol will conduct a manual review of the CRFs upon receipt. If any data issues are identified that cannot be resolved a query form will be sent to the researcher requesting clarification or correction of the problematic data. Following the manual review EpiData software V3.1 will be used for data entry logical checks and data verification to ensure consistency between the database data and the source documents. After data entry is completed and any problematic data has been corrected a blinded review and database lock will be conducted in accordance with the requirements of the statistical analysis plan.
