研究目的:

检测重症肌无力(Myasthenia gravis,MG)患者与健康人的外周血细胞单个核细胞中铁代谢指标(总铁及Fe2+含量、TF、TFR1、FtMt)、脂质过氧化指标(4-HNE、MDA、LPCAT3、LOX15)、糖基化指标(O-GlcNAc、OGT、OGA),铁死亡关键信号通路指标(PRDX2、MFN2、ACSL4)的表达差异,阐明重症肌无力与线粒体铁死亡的之间的关系,为重症肌无力寻求新的临床诊断及治疗方式。

Objectives of Study:

The aim of this study was to elucidate the relationship between myasthenia gravis and mitochondrial ferroptosis , and to seek new clinical diagnostic and therapeutic modalities for myasthenia gravis. The study was conducted by measuring iron metabolism indicators (total iron and Fe2+, TF, TFR1, FtMt), lipid peroxidation indicators (4-HNE, MDA, LPCAT3, LOX15), glycosylation indicators (O-GlcNAc, OGT, OGA), and differences in the expression of key signaling pathway indicators of ferroptosis (PRDX2, MFN2, ACSL4)

确定研究目的和所需数据,设计病例记录表模板,包括参与者的基本信息、医疗历史、干预措施、结果测量等。在研究过程中,使用CRF记录参与者的详细信息和研究数据。定期检查CRF的填写情况,将CRF存储在安全的地方,确保数据的准确性和完整性。

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

After determining the purpose of the study and the required data, we need to design case record forms that include basic information about the participants, medical history, interventions, outcome measures, etc. During the study, CRF was used to record participant details and study data. CRF filling was checked regularly and stored in a safe place to ensure the accuracy and completeness of the data.
