    过敏性鼻炎是一种常见的过敏性疾病,对身体健康有深远的影响。近年来,越来越多的人转向过敏性疾病,如过敏性鼻炎,过敏性哮喘,过敏性皮炎等。在过敏性鼻炎的发病率中,涵盖所有年龄。临床上常见的变应性鼻炎治疗方法有药物和免疫治疗,但这些疗法有一定的局限性。因此,迫切需要一种有效和经济的AR治疗方法。针灸在临床上广泛应用于各种疾病的治疗,但针刺治疗过敏性鼻炎(AR)的效果显著,针刺治疗AR的机制也是一个热点。针灸是传统的中医治疗方法之一,通过在皮肤上的特定位置按压针或其他方式以产生特殊感觉来达到治疗效果。其中,针灸,作为一种流行的治疗方法,引起了越来越多的关注。在这次审查中,我们概述了目前对针灸和AR的理解,以及目前研究针灸治疗AR的疗效和安全性的研究。
    Allergic rhinitis is a prevalent allergic diseases and has a profound impact on physical well-being. In recent years, more and more people have changed to allergic diseases, such as allergic rhinitis, allergic asthma, allergic dermatitis and so on. In the incidence of allergic rhinitis, covering all ages. The common clinical treatment of allergic rhinitis are drugs and immunotherapy, but these therapies have certain limitations. Therefore, an effective and economical treatment for AR is urgently needed. Acupuncture are widely used in the clinical treatment of various diseases, but the effect of acupuncture in the treatment of allergic rhinitis (AR) is significant, and the mechanism of acupuncture in the treatment of AR is also a hot spot. Acupuncture is one of the traditional treatment methods of traditional Chinese medicine, which achieves therapeutic effect by pressing a needle or other means at a specific location on the skin to produce a special sensation. Among them, acupuncture, as a popular treatment method, has attracted more and more attention. In this review, we provide an overview of the current understanding of acupuncture and AR, as well as current studies investigating the efficacy and safety of acupuncture for AR.

    心肌梗死(MI)可具有显著的身体和精神后果。抑郁症是心肌梗死后普遍存在的一种精神疾病,可降低患者的生活质量,增加患者的死亡率。然而,心梗和抑郁症之间的联系仍然被低估。这篇综述通过概述可能的病理生理机制,包括下丘脑-垂体-肾上腺轴和自主神经系统的失调,探讨了抑郁症与MI之间的潜在联系。凝血系统功能障碍,炎症,环境因素,还有,遗传因素。此外,抑郁症可能是用于MI治疗的药物(包括β受体阻滞剂)的不良事件,他汀类药物,或抗血小板剂。需要及早发现和管理心肌梗死患者的抑郁症,因此,对改善其整体预后至关重要。坚持治疗和定期随访可以确保对治疗的最佳反应。
    Myocardial infarction (MI) can have significant physical and mental consequences. Depression is a prevalent psychiatric condition after MI which can reduce the quality of life and increase the mortality rates of patients. However, the connection between MI and depression has remained under-appreciated. This review examines the potential connection between depression and MI by overviewing the possible pathophysiologic mechanisms including dysregulation of the hypothalamic-pituitary-adrenal axis and autonomic nervous system, coagulation system dysfunction, inflammation, environmental factors, as well as, genetic factors. Furthermore, depression can be an adverse event of medications used for MI treatment including beta-blockers, statins, or anti-platelet agents. The need for early detection and management of depression in patients with MI is, therefore, crucial for improving their overall prognosis. Adherence to treatments and regular follow-up visits can ensure the best response to treatment.

    自闭症谱系障碍(ASD)的病因是遗传,环境,和表观遗传。除了ASD患病率的性别差异外,这在男性中更常见3-4倍,也有不同的临床,分子,电生理学,和性别之间的病理生理差异。在人类中,患有ASD的男性有更多的外化问题(即,注意力缺陷多动障碍),更严重的沟通和社会问题,以及重复的动作。患有ASD的女性通常表现出较少的严重沟通问题,更少的重复和刻板的行为,但是更多的内在化问题,比如抑郁和焦虑。与男性相比,女性需要更高的与ASD相关的遗传变化负荷。大脑结构也有性别差异,连通性,和电生理学。ASD样行为的遗传或非遗传实验动物模型,当研究性别差异时,根据特定的模型,雄性和雌性动物之间显示出一些神经行为和电生理差异。我们以前曾对丙戊酸治疗的雄性和雌性小鼠的行为和分子差异进行研究,无论是产前还是产后早期,表现出类似ASD的行为,并发现两性之间的明显差异,与雄性相比,雌性小鼠在测量社交互动和大脑中更多基因表达变化的测试中表现更好。有趣的是,S-腺苷甲硫氨酸的共同给药减轻了ASD样行为症状,并且两种性别的基因表达变化程度相同。性别差异的潜在机制尚未完全了解。
    The etiology of autism spectrum disorder (ASD) is genetic, environmental, and epigenetic. In addition to sex differences in the prevalence of ASD, which is 3-4 times more common in males, there are also distinct clinical, molecular, electrophysiological, and pathophysiological differences between sexes. In human, males with ASD have more externalizing problems (i.e., attention-deficit hyperactivity disorder), more severe communication and social problems, as well as repetitive movements. Females with ASD generally exhibit fewer severe communication problems, less repetitive and stereotyped behavior, but more internalizing problems, such as depression and anxiety. Females need a higher load of genetic changes related to ASD compared to males. There are also sex differences in brain structure, connectivity, and electrophysiology. Genetic or non-genetic experimental animal models of ASD-like behavior, when studied for sex differences, showed some neurobehavioral and electrophysiological differences between male and female animals depending on the specific model. We previously carried out studies on behavioral and molecular differences between male and female mice treated with valproic acid, either prenatally or early postnatally, that exhibited ASD-like behavior and found distinct differences between the sexes, the female mice performing better on tests measuring social interaction and undergoing changes in the expression of more genes in the brain compared to males. Interestingly, co-administration of S-adenosylmethionine alleviated the ASD-like behavioral symptoms and the gene-expression changes to the same extent in both sexes. The mechanisms underlying the sex differences are not yet fully understood.

    动脉粥样硬化是一种慢性广泛分布的心血管疾病,是心血管事件的主要诱发因素,其中有心肌梗死和缺血性中风。动脉粥样硬化斑块形成是一个涉及不同机制的过程,其中炎症是最常见的。开发了大量的放射性药物来阐明不同阶段的斑块形成过程,其中一些对动脉粥样硬化斑块具有高度特异性。这篇综述总结了这些特定RP的临床前和小规模临床研究的当前核医学成像景观,没有标签FDG那么普遍,氟化钠,还有胆碱.这些包括氧化特异性表位成像,巨噬细胞,和其他细胞受体可视化,新血管生成,和巨噬细胞死亡成像。结果表明,特定的放射性药物在不同阶段的动脉粥样硬化斑块的病理生理声音成像中具有强度,但这也可能导致血管壁中低体积斑块的信号配准问题。
    Atherosclerosis is a chronic widespread cardiovascular disease and a major predisposing factor for cardiovascular events, among which there are myocardial infarction and ischemic stroke. Atherosclerotic plaque formation is a process that involves different mechanisms, of which inflammation is the most common. Plenty of radiopharmaceuticals were developed to elucidate the process of plaque formation at different stages, some of which were highly specific for atherosclerotic plaque. This review summarizes the current nuclear medicine imaging landscape of preclinical and small-scale clinical studies of these specific RPs, which are not as widespread as labeled FDG, sodium fluoride, and choline. These include oxidation-specific epitope imaging, macrophage, and other cell receptors visualization, neoangiogenesis, and macrophage death imaging. It is shown that specific radiopharmaceuticals have strength in pathophysiologically sound imaging of the atherosclerotic plaques at different stages, but this also may induce problems with the signal registration for low-volume plaques in the vascular wall.

    目的:确定中风个体走过狭窄开口时与避免碰撞行为相关的因素。
    方法:亚急性或慢性中风的参与者穿过狭窄的开口,必须避免与障碍物碰撞。病理生理学进行多元回归分析,运动功能,和判断能力作为预测变量;碰撞率和从非侧面进入开口的频率是结果变量。
    结果:纳入61名符合资格的卒中患者,年龄为63±12岁。30名参与者碰撞两次或更多次,37名参与者从非麻痹侧进入开口。较高的碰撞发生率与较慢的TimedUp和Go测试以及左右摇摆有关(赔率比,1.2和5.6;95%置信区间,1.1-1.3和1.3-28.2;p分别为.008和.025)。从非麻痹侧进入与丘脑病变有关,左侧偏瘫,和Brunnstrom第三阶段或更低(赔率比,6.6、8.7和6.7;95%置信区间,1.3-52.5、2.5-36.5和1.2-57.5;分别为p=.038、.001和.048)。
    结论:步行能力与避免障碍物碰撞有关,而病理生理特征和瘫痪程度与身体哪一侧先进入开口的偏好有关。改善行走能力的干预措施可以改善防撞。介入期间的回避行为根据病变位置而变化。
    BACKGROUND: High collision rates and frequency of entering the opening from non-paretic sides are associated with collision in individuals with stroke.
    OBJECTIVE: To identify factors associated with collision avoidance behavior when individuals with stroke walked through narrow openings.
    METHODS: Participants with subacute or chronic stroke walked through a narrow opening and had to avoid colliding with obstacles. Multiple regression analyses were conducted with pathophysiology, motor function, and judgment ability as predictor variables; collision rate and frequency of entering the opening from non-paretic sides were outcome variables.
    RESULTS: Sixty-one eligible individuals with stroke aged 63±12 years were enrolled. Thirty participants collided twice or more and 37 entered the opening from the non-paretic side. Higher collision occurrence was associated with slower Timed Up and Go tests and left-right sway (odds ratios, 1.2 and 5.6; 95% confidence intervals, 1.1-1.3 and 1.3-28.2; p = .008 and.025, respectively). Entering from non-paretic sides was associated with lesions in the thalamus, left-sided hemiplegia, and Brunnstrom stage 3 or lower (odds ratios, 6.6, 8.7, and 6.7; 95% confidence intervals, 1.3-52.5, 2.5-36.5, and 1.2-57.5; and p = .038,.001, and.048, respectively).
    CONCLUSIONS: Walking ability is associated with avoiding obstacle collision, while pathophysiological characteristics and degree of paralysis are associated with a preference for which side of the body enters an opening first. Interventions to improve walking ability may improve collision avoidance. Avoidance behavior during intervention varies depending on the lesion position.

    This article describes commonly used experimental and clinical biomarkers of neuronal injury and neurodegeneration for the evaluation of neuropathology and monitoring of therapeutic interventions. Biomarkers are vital for diagnostics of brain disease and therapeutic monitoring. A biomarker can be objectively measured and evaluated as a proxy indicator for the pathophysiological process or response to therapeutic interventions. There are complex hurdles in understanding the molecular pathophysiology of neurological disorders and the ability to diagnose them at initial stages. Novel biomarkers for neurological diseases may surpass these issues, especially for early identification of disease risk. Validated biomarkers can measure the severity and progression of both acute neuronal injury and chronic neurological diseases such as epilepsy, migraine, Alzheimer\'s disease, Parkinson\'s disease, Huntington\'s disease, traumatic brain injury, amyotrophic lateral sclerosis, multiple sclerosis, and other brain diseases. Biomarkers are deployed to study progression and response to treatment, including noninvasive imaging tools for both acute and chronic brain conditions. Neuronal biomarkers are classified into four core subtypes: blood-based, immunohistochemical-based, neuroimaging-based, and electrophysiological biomarkers. Neuronal conditions have progressive stages, such as acute injury, inflammation, neurodegeneration, and neurogenesis, which can serve as indices of pathological status. Biomarkers are critical for the targeted identification of specific molecules, cells, tissues, or proteins that dramatically alter throughout the progression of brain conditions. There has been tremendous progress with biomarkers in acute conditions and chronic diseases affecting the central nervous system.

    机械敏感性压电离子通道于2010年首次在小鼠神经母细胞瘤细胞系中报道,开辟了研究真核机械激活通道的组成和功能的新领域。在过去的十年里,在许多物种中发现了压电离子通道,如细菌,果蝇,和哺乳动物。在哺乳动物中,基本的生命活动,比如触觉,本体感受,听力,血管发育,和血压调节,依赖于压电离子通道的激活。累积证据表明,压电离子通道在肺血管发育和功能以及肺炎等疾病中起主要作用,肺动脉高压,呼吸暂停,和其他肺部相关疾病。在这次审查中,我们专注于报道组织中Piezos特定功能的研究,并强调其缺失或功能突变对呼吸系统的生理和病理影响.
    Mechanosensitive Piezo ion channels were first reported in 2010 in a mouse neuroblastoma cell line, opening up a new field for studying the composition and function of eukaryotic mechanically activated channels. During the past decade, Piezo ion channels were identified in many species, such as bacteria, Drosophila, and mammals. In mammals, basic life activities, such as the sense of touch, proprioception, hearing, vascular development, and blood pressure regulation, depend on the activation of Piezo ion channels. Cumulative evidence suggests that Piezo ion channels play a major role in lung vascular development and function and diseases like pneumonia, pulmonary hypertension, apnea, and other lung-related diseases. In this review, we focused on studies that reported specific functions of Piezos in tissues and emphasized the physiological and pathological effects of their absence or functional mutations on the respiratory system.

    水通道蛋白(AQP)的各种同种型在人体不同组织和器官中的表达使其成为负责维持细胞稳定性和完整性的可行候选者,因为它们的参与已在许多病理生理条件下得到充分证明。由这些AQP引起的细胞环境的任何改变都会产生严重的下游效应,例如细胞渗透压的变化,volume,离子组成,信号通路,甚至在细胞内第二信使的水平,因此,促进癌症等疾病的发生。水的平衡改变了,神经退行性疾病中神经元破坏和氧化应激引起的细胞外离子和氨基酸神经递质也提出了这些AQP在这些疾病中的作用。AQPs在多种炎症过程如肺损伤中的关联,脑水肿,视神经脊髓炎,通过它们在动物和人类疾病中的失调表现出的结肠炎确实是它们在保护和对包括细菌感染在内的各种有害刺激的反应中的作用的开眼界。肾脏疾病,如肾源性糖尿病,常染色体显性多囊肾病和急性肾损伤是与水通道蛋白功能失调有关的一些病理生理条件。此外,AQP7和AQP9等水甘油孔素的功能异常使它们成为肥胖等疾病的原因,非酒精性脂肪性肝病和非酒精性脂肪性肝炎。在这篇评论文章中,我们介绍了我们目前对AQP在这些代谢紊乱的原因中的作用的理解,以及如何靶向它们对大多数这些疾病如癌症具有有希望的治疗潜力。肾脏疾病甚至心血管疾病。
    The expression of various isoforms of aquaporins (AQPs) in different tissues and organs of the body makes it a viable candidate for being responsible for maintaining cell stability and integrity as their involvement has been well documented in a number of pathophysiological conditions of the human body. Any alteration in the cellular environment brought about by these AQPs creates severe downstream effects like changes in cellular osmolality, volume, ionic composition, signaling pathways and even in the levels of intracellular second messengers and, as such, facilitates the occurrence of diseases like cancer. The altered equilibrium of water, extracellular ions and amino acid neurotransmitters caused by neuronal destruction and oxidative stress in neurodegenerative diseases proposed the role of these AQPs in these diseased conditions as well. The association of AQPs in a variety of inflammatory processes like lung injury, brain edema, neuromyelitis optica, and colitis as manifested through their dysregulation both in animal and human diseases is truly an eye opener for their role in protection and reaction to various noxious stimuli including bacterial infection. Renal diseases like nephrogenic diabetes inspidus, autosomal dominant polycystic kidney disease and acute kidney injury are some of the pathophysiological conditions related to malfunctioning of aquaporins. Besides, the malfunctioning of aquaglyceroporins like AQP7 and AQP9 makes them responsible for disorders like obesity, nonalcoholic fatty liver disease and non-alcoholic steatohepatitis. In this review article, we present our current understanding of the role of AQPs in the causation of these metabolic disorders and how targeting them holds promising therapeutic potential for most of these diseases like cancer, renal diseases and even cardiovascular disorders.
