Circadian influence on intrusive re-experiencing in trauma survivors' daily lives. [PDF]
Eur J Psychotraumatol, 2022 Background: The core clinical feature of posttraumatic stress disorder (PTSD) is recurrent re-experiencing in form of intrusive memories. While a great number of biological processes are regulated by sleep and internal biological clocks, the effect of 24-

Zhongshan Daxue xuebao. Yixue kexue ban, 2019 生物钟是生物体对环境长期适应而形成的自主计时机制。生物钟基因调节人体多项生理活动，比如睡眠-觉醒、激素分泌、细胞代谢和免疫调节等，其目标是使细胞、组织以及器官能够有序、协同作用，并呈现明显的节律。女性生殖功能受下丘脑-垂体-卵巢轴的昼夜节律调控。由于外界因素引起的昼夜节律中断与女性各种生殖功能障碍的发生发展有关，包括月经失调、流产和生育力下降等。本文旨在从月经周期中卵泡发育的调控、排卵、胚胎着床以及妊娠维持等多个方面介绍生物钟在女性生殖方面所起作用。

Zhongshan Daxue xuebao. Yixue kexue ban, 1993 本文应用动态心电图,探讨了22例室性早搏密度自发变动的特性。结果表明:室性早搏密度越高,自发变动程度越小;小时与小时之间较天与天之间室性早搏密度的变动幅度更大;相隔8天以内,天与天之间室性早搏密度的变动无明显差异,室性早搏密度呈昼夜节律分布,高峰出现在日间。研究结果将为非侵入性药效评价方法设计提供依据。

Zhongguo cuzhong zazhi, 2023 昼夜节律紊乱的原因可分为内部因素和外部因素，内部因素指内在昼夜节律睡眠-觉醒调节机制障碍；外部因素包括社交时差、轮班工作、夜间人造光、跨时区旅行、熬夜、饮食不规律等。内部/外部因素可以导致中枢和外周的生物钟紊乱，生物钟基因调控几乎整个基因组的表达，生物钟紊乱可导致葡萄糖-胰岛素代谢紊乱、高血压、血脂异常、免疫激活、肥胖、早衰等，而这些因素也正为卒中的危险因素。近年来，昼夜节律紊乱及其导致的上述脑血管病危险因素与卒中发病风险的关系日益受到关注。本文就昼夜节律紊乱增加卒中风险机制的研究进展进行综述 ...

Zhongguo cuzhong zazhi, 2019 基于昼夜节律的相关认识阐述卒中发病的时间规律及影响因素，探讨卒中防控的新策略。 收集、整理现代医学关于昼夜节律与卒中发病时间的相关性文献，进行综合分析。卒中发病存在显 著的昼夜差异并具有周期性变化，血压、血糖、血脂、Hcy等相关因素出现昼夜节律紊乱可能是导致 卒中存在高发时段的部分原因。适时服用防治药物，调整生活方式，保持自身昼夜节律的稳定，是健 全卒中防控策略和降低卒中发病风险的重要措施。 Abstract: To explore the circadian variation in ...
