研究目的:

在中国社区的老年人中,以中药营养疗法(Chinese medicine nutrition therapy,CMNT)为干预方法,以认知功能评分和糖尿病缓解为主要观察指标,从CMNT方案减轻高血糖负荷和调节肠道微生物群的角度探讨其对2型糖尿病合并认知功能障碍患者认知功能和糖尿病缓解的影响。

Objectives of Study:

In the elderly in Chinese community Chinese medicine nutrition therapy (CMNT) was used as intervention method cognitive function score and diabetes remission were used as main observation indicators and the effects of CMNT on cognitive function and diabetes remission in type 2 diabetes patients with cognitive dysfunction were investigated from the perspective of reducing hyperglycemic load and regulating intestinal microbiota.

随机方法(请说明由何人用什么方法产生随机序列):

对年龄和性别采用分层随机化方法,由一位指定的研究人员根据计算机随机数字生成器生成的随机分配顺序,交给研究负责人,每位受试者的序号与产生的随机数字按顺序对应,大号随机数字组为CMNT组,小号随机数字组为常规护理组,将受试者按照1:1的比例随机分配到CMNT组或常规护理组。

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

Stratified randomization method was adopted for age and gender. A designated researcher was assigned to the study leader according to the random assignment order generated by a computer random number generator. The serial number of each subject corresponded to the random number generated in order the large random number group was CMNT group and the small random number group was usual care group. Participants were randomly assigned to either the CMNT group or the usual care group in a 1:1 ratio.

盲法:

所有评估结果和数据分析的研究人员对分组情况不知情,但受试者和护理人员知情。

Blinding:

All the researchers who evaluated the results and analyzed the data were not aware of the grouping but the subjects and caregivers were.

使用ResMan平台进行电子数据的采集和管理。记录表由研究组放置在单独的房间里,存放在一个带锁的抽屉里。电子数据将以密码保护的文件形式保存在安全的计算机数据库中。本研究生成的科学报告将匿名。只有授权人员才能访问随机化数据,才能访问执行这项工作所需的专用信息。研究结果将通过电子邮件或电话发送至参与者。

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

Use ResMan platform to collect and manage electronic data. The records are kept by the research team in a separate room in a locked drawer. Electronic data will be stored in a secure computer database in the form of password-protected files. Scientific reports generated from this study will be anonymous.
