研究目的:

探索多种膈肌超声检测项目(包括膈肌动度、膈肌收缩峰值速度、膈肌增厚、横波弹性成像中的膈肌剪切模量、二维散斑跟踪成像中的膈肌应变值、超声成像灰度分析中的膈肌回声密度)作为判断重症肌无力患者膈肌功能及多种结局是否发生(包括发生呼吸道感染、病情变化、药物变更)的标志物的价值。  

Objectives of Study:

Explore the value of various diaphragmatic ultrasound detection items (including diaphragmatic motility, peak systolic velocity, diaphragmatic thickening, diaphragmatic shear modulus in transverse wave elastography, diaphragmatic strain value in two-dimensional speckle tracking imaging, and diaphragmatic echo density in grayscale analysis of ultrasound imaging) as biomarkers for determining diaphragmatic function and various outcomes in patients with myasthenia gravis, including respiratory infections, disease changes, and drug modifications.

在获取项目负责人和研究对象同意的情况下,待研究结题后(预计2026年5月起),可以通过邮件feixiao81@126.com联系项目负责人获取脱敏数据。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

With the consent of the project leader and research subjects, after the research is completed (expected to start in May 2026), it can be done via email feixiao81@126.com Contact the project leader to obtain desensitization data.

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:

在获得患者知情同意和符合伦理原则的前提后,本研究使用CRF表。CRF表以纸质和电子数据库方法保存。数据采集的时间为患者知情同意后,参与本研究评估的时间,采集一次。CRF表录入电子数据库需要本研究团队两人独立录入,如有差异,核对后更改录入。纸质和电子数据原件由我科临床试验档案专柜登记保存。

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

After obtaining informed consent from patients and adhering to ethical principles, this study used CRF forms. The CRF form is saved using both paper and electronic database methods. The time for data collection is once after the patient's informed consent and participation in the evaluation of this study. The CRF form needs to be entered into the electronic database independently by two members of our research team. If there are any discrepancies, they should be checked and corrected before entering. The original paper and electronic data shall be registered and stored at the clinical trial archives counter of our department.
