Cells are the fundamental units of biological systems and exhibit unique development trajectories and molecular features. Our exploration of how the genomes orchestrate the formation and maintenance of each cell, and control the cellular phenotypes of various organismsis, is both captivating and intricate. Since the inception of the first single-cell RNA technology, technologies related to single-cell sequencing have experienced rapid advancements in recent years. These technologies have expanded horizontally to include single-cell genome, epigenome,proteome, and metabolome, while vertically, they have progressed to integrate multiple omics data and incorporate additional information such as spatial sc RNA-seq and CRISPR screening. Single-cell omics represent a groundbreaking advancement in the biomedical field,offering profound insights into the understanding of complex diseases, including cancers. Here, we comprehensively summarize recent advances in single-cell omics technologies, with a specific focus on the methodology section. This overview aims to guide researchers in selecting appropriate methods for single-cell sequencing and related data analysis.

目的研究异丙酚对脂多糖(LPS)诱导的急性肺损伤大鼠肺组织Toll样受体4(TLR-4)表达的影响。方法24只Wistar大鼠随机分为3组,对照组(C组)、肺损伤组(LPS组)和异丙酚(P组)。分别于给药前、给药1h、3h和5h记录平均动脉压(MAP)和心率(HR)、行动脉血气分析。给药5h后测定TLR-4mRNA和蛋白表达,观察肺组织病理学及支气管肺泡灌洗液(BALF)中TNF-α的表达。结果与C组比较,LPS组和P组MAP和PaO2均有下降(P<0.05)。LPS组TLR-4mRNA及蛋白表达较C组升高(P<0.05)。P组TLR-4mRNA及蛋白表达较LPS组低(P<0.05)。各组肺组织损伤程度从轻至重分别为C组、P组、LPS组。各组BALF中TNF-α水平从低到高分别为C组、P组、LPS组。结论异丙酚有抗炎作用,能明显改善LPS诱导的急性肺损伤,其作用机制可能是下调了TLR4蛋白及基因的表达水平。
