研究目的: |
本研究拟在二甲双胍治疗基础上,联合ProSci-246干预,纳入T2DM合并肥胖患者样,从肠道菌群-代谢轴角度探讨其对综合代谢的影响,并通过宏基因组学和代谢组学分析潜在机制。为T2DM的个性化治疗提供新策略,也将为肠道微生态在代谢性疾病及共病神经行为症状中的作用提供理论依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study plans to add ProSci-246 intervention on the basis of metformin therapy in patients with T2DM and obesity, aiming to explore its effects on comprehensive metabolism from the perspective of the gut microbiota–metabolism axis. Through metagenomic and metabolomic analyses, the underlying mechanisms will be investigated. This study is expected to provide a new strategy for personalized treatment of T2DM and also offer a theoretical basis for understanding the role of gut microecology in metabolic diseases and associated neurobehavioral symptoms. |

随机方法(请说明由何人用什么方法产生随机序列): |
由不参与本研究方案实施及结局评价的独立统计人员,采用 SAS 9.4 或 R 语言软件生成随机数字表,采用区组随机化方法(区组大小为 4 或 6),按 1:1 比例将符合纳入标准的受试者随机分配至试验组(二甲双胍联合 ProSci-246)或对照组(二甲双胍联合安慰剂)。随机序列分配隐藏于顺序编号、不透光、密封的信封中,受试者入组时按顺序拆封并分配至相应组别。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The random sequence is generated by an independent statistician who is not involved in the implementation of the protocol or outcome assessment, using SAS 9.4 or R software. A blocked randomization method (block size of 4 or 6) is used to allocate eligible participants in a 1:1 ratio to either the experimental group (metformin combined with ProSci-246) or the control group (metformin combined with placebo). The allocation sequence is concealed in sequentially numbered, opaque, sealed envelopes. When a participant is enrolled, the envelope is opened in order, and the participant is assigned to the corresponding group. |

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: |
本研究采用病例报告表(CRF)与电子数据采集系统相结合的方式进行数据采集和管理。CRF 记录受试者人口学特征、病史、体格检查、实验室检测、量表评估及不良事件等信息。电子数据采集采用电子采集与病历管理系统进行双人独立录入、逻辑核查及数据锁定。数据管理由主要研究者监督,任何数据修改均需记录修改原因及时间。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
In this study, data collection and management are performed using a combination of a Case Report Form (CRF) and an electronic data capture system. The CRF records information on participants' demographic characteristics, medical history, physical examination, laboratory tests, scale assessments, and adverse events. Electronic data capture is conducted using an electronic data capture and medical record management system, which allows for double independent data entry, logical verification, and data locking. Data management is supervised by the principal investigator, and any data modification must be recorded with the reason and time of the modification. |
