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.

社会焦虑和抑郁现象日益严重。为理解与探索数媒时代焦虑、抑郁的引致因素及应对策略,研究采用系统性文献综述方法,基于情感事件理论和社会比较理论构建框架,梳理了社会比较的不同亚型与焦虑、抑郁的关系以及网络媒体环境的权变作用。研究发现,消极社会比较(传统上行比较和下行同化比较)可能会引发焦虑和抑郁,社交网络平台对此负面影响具有催化作用;而情绪比较和下行对比比较可以缓解焦虑和抑郁,网络健康社区促进了情绪比较的积极作用的发挥。研究推进了社会比较理论在情绪情感领域的应用,确定了焦虑、抑郁与网络健康社区可供性的关联,也为网络社区服务、运营和设计的原则提供参考和借鉴以帮助个体应对心理健康问题。研究还指出焦虑、抑郁和社会比较关系后续研究的可能路径和方向。

目的探讨低出生体质量儿发生情况和影响因素,为采取有效干预措施和提高人口素质提供理论参考。方法收集吉林市5家医院产科2018年1-12月出生的新生儿。采用自行设计的调查表,收集低出生体质量新生儿及其母亲的一般情况。采用Epidata 3.1软件建立数据库,SPSS 23.0软件进行数据分析处理,通过t检验、χ^(2)检验和多元Logistic回归分析判断可能导致低出生体质量儿的相关危险因素。结果吉林市低出生体质量儿的发生率为3.16%。低出生体质量儿在出生胎龄、Apgar评分及先天缺陷方面与非低出生体质量儿比较差异有统计学意义(P<0.05);低出生体质量儿与非低出生体质量儿母亲比较,母亲生育年龄、既往孕产史、妊娠胎数、妊娠高血压疾病、胎盘早剥等因素差异有统计学意义(P<0.05)。多元Logistic回归分析提示,早产、胎儿性别、胎儿出生缺陷、母亲妊娠年龄、妊娠胎数、妊娠高血压疾病及胎盘早剥可能是导致低出生体质量儿的危险因素。结论吉林市低出生体质量儿的发生率为3.16%,低于全国平均水平。早产、胎儿性别、胎儿出生缺陷、母亲妊娠年龄、妊娠胎数、妊娠高血压疾病及胎盘早剥可能是导致低出生体质量儿的危险因素。
