ObjectiveThis study aimed to evaluate the effect of different combinations of rTMS and cognitive training (rTMS-COG) on PSCI and identify the optimal combination protocol.
MethodsA cerebral infarction rat model was established by transient middle cerebral artery occlusion (tMCAO). The Morris water maze test was conducted to assess the cognitive function of rats. RNA sequencing and bioinformatics analysis were employed to study the underlying mechanisms.
ResultsrTMS, COG and rTMS-COG all had beneficial effects on PSCI, while cognitive training immediately after rTMS (rTMS-COG0h) achieved a better effect than cognitive training 1 h and 4 h after rTMS, rTMS and COG. We identified 179 differentially expressed genes (DEGs), including 24 upregulated and 155 downregulated genes, between the rTMS-COG0h and rTMS groups. GO analysis revealed that the major categories associated with the DEGs were antigen procession and presentation, regulation of protein phosphorylation and axoneme assembly. KEGG analysis showed that the DEGs were enriched in processes related to phagosome, circadian entrainment, dopaminergic synapse, apelin signaling pathway, long-term depression, neuroactive ligand-receptor interaction, axon guidance and glucagon signaling pathway. PPI analysis identified Calb2, Rsph1, Ccdc114, Acta2, Ttll9, Dnah1, Dlx2, Dlx1, Ccdc40 and Ccdc113 as related genes.
ConclusionsThese findings prompt exploration of the potential mechanisms and key genes involved in the effect of rTMS-COG0h on PSCI.

目的系统评价有氧运动影响老年失眠患者睡眠质量效果。方法检索中国知网、万方、PubMed、Webofscience、Embase、CINAHL和Scopus文献数据库，从建库至2020年6月22日间使用有氧运动干预老年失眠患者睡眠质量的随机对照实验。对符合纳入标准12篇文献中的873例实验对象运用RevMan5.4版软件进行Meta分析。结果有氧运动可显著降低匹兹堡睡眠质量指数得分[SMD＝－0.9；95%CI(－1.29，－0.51)]和主观睡眠质量指数得分[SMD＝－2.74；95%CI[－4.24，－
线粒体自噬是一种自噬的形式，是目前已知的选择性清除线粒体的途径。近年来，B淋巴细胞瘤-2/腺病毒E1B19kDa相互作用蛋白3(BNIP3)因其在线粒体自噬中的潜在作用而备受关注。尽管对BNIP3在线粒体自噬中的调控机制认识不断增加，但在肌源性挛缩的发生过程中，BNIP3介导的线粒体自噬的作用及其机制仍知之甚少。在肌源性挛缩发生过程中，典型的病理特征表现为骨骼肌萎缩和纤维化。因此，本文对BNIP3及其在线粒体自噬中的调控机制进行了系统回顾，并对BNIP3介导的线粒体自噬影响骨骼肌萎缩和纤维化的研究进行了综
脑损伤是造成儿童残疾和死亡的主要原因之一，早期客观评估患儿病情变化对改善预后意义重大。近红外光谱技术(NIRS)是一项利用近红外光监测局部脑氧饱和度(rcSO2)的脑功能成像技术，具有无创、实时、连续监测rcSO2等优势。NIRS可以在床旁为脑损伤患儿提供更多关于脑的氧供信息，及时发现脑血氧信息的异常，其合理的使用可以为脑损伤患儿的临床诊断、治疗和预测预后等方面提供重要信息。本文概述了NIRS的基本信息，并对其在儿童脑损伤的应用情况以及最新进展进行综述，以期为NIRS在儿童脑损伤的临床应用提供参考。
卒中后吞咽困难(PSD)是脑卒中后常见的并发症，考虑到PSD的发病率及其造成的严重后果，PSD患者吞咽功能有效、快速的恢复极其重要。近年来重复经颅磁刺激(rTMS)技术兴起，各项研究层出不穷，为PSD的治疗提供了新的方法手段。本文从机制探讨和临床应用两大方面对PSD的发生机制、PSD恢复的相关机制、rTMS相关参数的设定、rTMS治疗PSD相关临床实践方案的选择及疗效等进行综述，以期对未来的研究方向提供一定思路。
痉挛型脑瘫患儿行走时因关节畸形和肌肉挛缩影响，多存在异常运动模式，严重影响患儿的生活质量。重复经颅磁刺激(rTMS)是一项对痉挛型脑瘫患儿有效的辅助治疗方法。本文就rTMS治疗痉挛型脑瘫患儿运动功能的作用和机制做一综述，旨在为临床治疗和研究提供参考和借鉴。
