目的研究苦参碱对N-甲基-N'-硝基-N-亚硝基胍(MNNG)诱导大鼠胃黏膜损伤的影响及机制。方法将75只Wister大鼠随机分为空白组、模型组、(100、150、200)mg/kg苦参碱处理组。除空白组外,其余各组采用MNNG复合造模方法建立胃黏膜损伤大鼠模型。造模成功后,苦参碱处理组大鼠分别腹腔注射(100、150、200)mg/kg苦参碱,连续给予45 d。最后一次给药后,测定各组实验大鼠的体质量、24 h饮食饮水量。处死大鼠后收集组织样本,ELISA测定胃黏膜组织白细胞介素1β(IL-1β)、IL-4、γ干扰素(IFN-γ)和肿瘤坏死因子α(TNF-α)水平;HE染色观察胃黏膜组织的病变情况,免疫组织化学染色检测胃黏膜组织血管内皮生长因子C(VEGF-C)和血管内皮生长因子受体3(VEGFR3)的表达,Western blot法检测各组大鼠胃组织Bcl2、BAX、胱天蛋白酶3(caspase-3)、细胞色素C(Cyt-C)、Toll样受体4(TLR4)、髓样分化因子88(MyD88)和核因子κB p65(NF-κBp65)的蛋白水平。结果苦参碱处理的胃黏膜损伤大鼠的饮食饮水量、体质量增加,胃黏膜组织的损伤减轻;苦参碱能够显著降低胃黏膜组织VEGF-C和VEGFR3表达,增加Bcl2蛋白水平并降低BAX、caspase-3、Cyt-C、TLR4、MyD88和NF-κBp65蛋白水平。结论苦参碱能够减轻MNNG引起的大鼠胃黏膜损伤,可能与其抑制VEGF-C/VEGFR3和NF-κB/TLR4信号通路有关。

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.

目的探讨心理生理学方法在双重任务脑力负荷评定中的意义。方法采用事件相关电位Ｐ３波潜时（ＬＡＴ）和波幅（ＡＭＰ）、逐次心跳间期（ＩＢＩ）及心率变异性（ＨＲＶ）、逐次呼吸间期（ＩＲＩ）及呼吸变异性（ＲＲＶ）、眨眼率（ＢＲ）等心理生理学指标，评定了１６名男性青年受试者完成三种不同难度双重任务时的脑力负荷。双重任务由视觉追踪主任务和Ｓｔｅｒｎｂｅｒｇ副任务组成，其难度由主任务目标运动的速度和维度控制。结果①随任务难度增加，Ｐ３波ＬＡＴ延长（Ｐ＜０．０１），ＡＭＰ无显著性变化（Ｐ＞０．０５）；②ＩＢＩ及ＨＲＶ在中等难度任务时最小，其中ＩＢＩ在任务间有显著性差异（Ｐ＜０．０１）；③ＩＲＩ随任务难度增加而减小（Ｐ＜０．０５），ＲＲＶ任务间无显著性差异（Ｐ＞０．０５）；④ＢＲ在三种任务条件与对照条件时相比显著降低（Ｐ＜０．０１）。结论各指标与脑力负荷均有一定关系，但单一指标评定脑力负荷有局限性，多种心理生理学指标综合评定是双重任务条件下脑力负荷评定更为适宜的方法。
