研究目的: |
(1)探究VNS对肠道菌群、代谢产物的影响以及疗效与肠道菌群和代谢物相关性; (2)借助肠道菌群和代谢物,探究VNS后预测癫痫发作频率生物标志物。 |
||||||||||||||||||||||
|
Objectives of Study: |
(1) To investigate the effects of Vagus Nerve Stimulation (VNS) on gut microbiota and metabolites, as well as the correlation between therapeutic efficacy and alterations in gut microbiota and metabolites. (2)Identify predictive biomarkers for epileptic seizure frequency through multi-omics analysis of gut microbiota dynamics and metabolic pathway variations following VNS intervention. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection: Specially designated clinicians are responsible for guiding patients in specimen collection, while another doctor is responsible for collecting basic information and follow-up information, and recording the patients' data in the CRF (Case Report Form). Data Management: The research leader is directly responsible for this aspect, and designated doctors are tasked with entering the information into an electronic collection and management system. |
