研究目的:

通过横断面研究探究DMTN与DKD肾功能损伤关联性,确定不同阶段DKD人群血清DMTN指标的参考阈值。借助前瞻性队列研究(建模人群),获取T2DM、DKD人群相关的参数,并通过ELISA明确DMTN表达数值,利用机器学习法建立T2DM进展为DKD的预测模型。在前瞻性队列(验证人群)中验证上述预测模型的有效性。  

Objectives of Study:

The association between DMTN and renal impairment in DKD was explored by cross-sectional study, and the reference thresholds of serum DMTN indexes in different stages of DKD population were determined. With the help of a prospective cohort study (modeling population), the parameters related to T2DM and DKD populations were obtained, and the values of DMTN expression were clarified by ELISA, so that a prediction model for the progression of T2DM to DKD could be established using the machine learning method. The validity of the above prediction model was verified in a prospective cohort (validation population).

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、数据的录入 课题研究者根据受试者的检测结果录入依托于本科室MMC数据库,此数据库录入过程中数据及时、完整、正确地录入数据库,录入采用相应地数据库系统双人双机录入,之后对数据库进行两遍对比,期间若发现问题及时返回核对。 2、数据核查和管理的内容和方式 当所有病例报告表经双份输入并核对无误后,完成数据库检查报告,其内容包括:研究完成情况(含脱落受试者清单)、入选/排除标准检查、完整性检查、离散数据检查。 3、数据存档 完成数据录入和核查后,保存数据库文件。电子数据文件包括数据库、检查程序、 分析程序、分析结果、编码本和说明文件等,应分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。

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

1. Data entry The researchers according to the subject's test results into the MMC database relying on the Department of this database entry process, this database entry process data in a timely, complete and correct entry into the database, entry using the appropriate database system, double machine entry, and then the database for two comparisons, during the period of time, if problems found in a timely manner to return to the check. 2. Content and manner of data verification and management When all case report forms have been double-entered and checked for accuracy, a database check report is completed, which includes: study completion (including a list of dislodged subjects), inclusion/exclusion criteria check, completeness check, and discrete data check. 3. Data archiving After completing data entry and verification, save the database file. The electronic data files include the database, checking procedures, analytical procedures, analytical results, codebooks, and description documents, etc. They should be categorized and saved with multiple backups on different disks or recording media, and stored properly to prevent damage.
