研究目的:

本研究在不改变临床常规麻醉方案的前提下,采用受试者自身前后配对设计,通过单细胞转录组测序技术,比较丙泊酚临床麻醉前(T0)与首次丙泊酚给药后30±5分钟(T1)外周血单个核细胞(PBMC)的转录组特征变化,重点分析免疫细胞亚群构成及转录状态的动态改变,并评估铁死亡相关基因集及神经毒性相关通路的早期分子响应,为麻醉相关分子机制研究提供探索性证据。  

Objectives of Study:

In this study, without altering the standard clinical anesthesia protocol, a pre-post paired design using the subjects’ own samples was employed. Through single-cell transcriptomics sequencing, we compared changes in the transcriptomic profiles of peripheral blood mononuclear cells (PBMCs) between pre-anesthesia (T0) and 30 ± 5 minutes after the first administration of propofol (T1). The study focuses on analyzing dynamic changes in the composition and transcriptional status of immune cell subsets, and evaluates early molecular responses in ferroptosis-related gene sets and neurotoxicity-related pathways, thereby providing exploratory evidence for research into anesthesia-related molecular mechanisms.
