    背景:在调查对光的非视觉反应的研究中,报告光特征没有共识。该项目旨在为基于实验室的调查制定报告清单,以研究光线对非视觉生理学的影响。
    方法:进行了国际专家参与的四步改进的Delphi过程(三轮基于问卷的反馈和一次面对面的小组讨论),以就清单中的项目达成共识。在达成共识之后,由此产生的清单在试点阶段由独立专家进行了测试。
    结果:与报告基于光的干预措施有关的61个项目的初始列表浓缩为包含25个项目的最终清单,基于专家的共识(最终n=60)。无论研究问题或背景如何,都认为有九个项目需要报告。每个项目的描述在随附的解释和详细说明(E&E)文档中提供。独立的试点测试阶段导致检查表和E&E文档中的少量文字说明。
    结论:ENLIGHT清单是第一个基于共识的清单,用于记录和报告人类研究中基于眼部光线的干预措施。核对表的实施将通过确保全面的文件,增强基于光的研究的影响,增强再现性,并实现跨研究的数据聚合。
    背景:欧洲高级研究所(NETIAS)建设性高级思维(CAT)计划网络;亨利·惠康爵士博士后奖学金(惠康信托,204686/Z/16/Z);荷兰卫生研究与发展组织VENI研究金(2020-09150161910128);美国国防部赠款(W81XWH-16-1-0223);新加坡国立大学(NUHSRO/2022/038/Startup/08);和新加坡国家研究基金会(NRF2022-THE004-0002)。
    BACKGROUND: There is no consensus on reporting light characteristics in studies investigating non-visual responses to light. This project aimed to develop a reporting checklist for laboratory-based investigations on the impact of light on non-visual physiology.
    METHODS: A four-step modified Delphi process (three questionnaire-based feedback rounds and one face-to-face group discussion) involving international experts was conducted to reach consensus on the items to be included in the checklist. Following the consensus process, the resulting checklist was tested in a pilot phase with independent experts.
    RESULTS: An initial list of 61 items related to reporting light-based interventions was condensed to a final checklist containing 25 items, based upon consensus among experts (final n = 60). Nine items were deemed necessary to report regardless of research question or context. A description of each item is provided in the accompanying Explanation and Elaboration (E&E) document. The independent pilot testing phase led to minor textual clarifications in the checklist and E&E document.
    CONCLUSIONS: The ENLIGHT Checklist is the first consensus-based checklist for documenting and reporting ocular light-based interventions for human studies. The implementation of the checklist will enhance the impact of light-based research by ensuring comprehensive documentation, enhancing reproducibility, and enabling data aggregation across studies.

    对与太阳直接照射有关的人眼蓝光危害进行了定量评估。对于六种辐射情况,将缺失的眼睛保护与九种不同的带有和不带有优化的蓝光滤光片的商用太阳镜的保护进行了比较。太阳辐照度的测量是在地球表面以及客机驾驶舱内12公里的高度上进行的。根据测量数据计算照射时限。在此范围内,达到国际非电离辐射防护委员会建议的最大蓝光剂量100Jm-2,并根据标准ICE62471为灯具的安全操作所必需。结果表明,在没有眼睛保护的情况下直接观察阳光时,蓝光剂量限制在不到3s的时间内就会被违反。对于没有优化的蓝光滤光片的3类太阳镜,在地球表面观察到10到25s的时间限制,在12公里的高度观察到7到8s。经过调查的3类太阳镜具有优化的蓝光防护功能,适合交通使用,允许在地球表面上的时间限制超过40秒,在客机驾驶舱内的时间限制为18至95秒。该研究的结果是,可以使用现有的限制来量化与太阳辐射有关的蓝光危害的眼睛防护,并且太阳镜的选择是相关的:针对蓝光危害进行优化的值得交通的太阳镜比非优化太阳镜提供更好的防护。
    A quantitative assessment of the blue light hazard for the human eye related to direct solar irradiation is presented. For six radiation situations, missing eye protection was compared to protection by nine different commercial sunglasses with and without an optimized blue light filter. Measurements of the solar irradiance were performed on Earth\'s surface as well as at an elevation of 12 km in the cockpit of an airliner. An irradiation time limit was calculated from the measurement data, within which the maximum blue light dose of 100 J m -2 , recommended by the International Commission on Non-Ionizing Radiation Protection and mandatory for the safe operation of lamps according to the norm ICE 62471, is reached. The results suggest that the blue light dose limit is violated within less than 3 s when looking without eye protection directly into the sun. For Category 3 sunglasses without the optimized blue light filter, time limits of 10 to 25 s on Earth\'s surface and 7 to 8 s at 12 km altitude were observed. The investigated Category 3 sunglasses with optimized blue light protection and suited for traffic use allow a time limit of more than 40 s on Earth\'s surface and 18 to 95 s in the airliner\'s cockpit. The outcome of the study is that the eye protection against blue light hazard related to solar radiation can be quantified using existing limits and that the choice of sunglasses is relevant: Traffic-worthy sunglasses optimized for protection against blue light hazard offer a better protection than non-optimized sunglasses.

    这项研究的目的是调查使用ESC/ESH或ACC/AHA指南时属于不同BP组的无症状个体的视网膜和周围微血管功能。通过动态视网膜血管分析和数字热监测评估358名参与者的视网膜和周围微血管功能。分别。还评估了血压和血脂组。在属于ACC/ASH分类的所有组中测量的视网膜血管功能在年龄匹配的正常人群的正常值内。根据ESC/ESH指南,被归类为1级高血压的个体,然而,表现出显著降低的动脉基线(p=0.0004)和MC(p=0.040),与年龄匹配的正常人相比,slopeAD较高(p=0.0018)和静脉MC降低(p=0.0446)。此外,他们也有明显的下动脉基线,动脉BDF,根据ACC/ASH指南,MD和MC比个体归类为1期高血压(分别为p=0.00022,p=0.0179,p=0.0409和p=0.0329)。与分级的ACC/ASHI期高血压相比,ESC/ESHI级的外周血管反应性(aTR)较低(p=0.0122)。这项研究的结论是,微血管功能障碍仅在ESC/ESH1级高血压患者中存在多个水平。在确定患有早期高血压变化的个体的个性化护理时,此观察结果可能很重要。
    The aim of this study was to investigate retinal and peripheral microvascular function in asymptomatic individuals that fall into different BP groups when using either the ESC/ESH or the ACC/AHA guidelines. Retinal and peripheral microvascular function was assessed in 358 participants by means of dynamic retinal vessel analysis and digital thermal monitoring, respectively. Blood pressure and lipid panel were also evaluated. Retinal vascular function measured in all groups belonging to the ACC/ASH classifications were within the normal values for age-matched normal population. Individuals classed as grade 1 hypertension according to the ESC/ESH guidelines, however, exhibited a significantly decreased artery baseline (p = 0.0004) and MC (p = 0.040), higher slopeAD (p = 0.0018) and decreased vein MC (p = 0.0446) compared to age matched normal individuals. In addition, they also had significant lower artery baseline, artery BDF, MD and MC than individuals classed as stage 1 hypertension based on the ACC/ASH guidelines (p = 0.00022, p = 0.0179, p = 0.0409 and p = 0.0329 respectively). Peripheral vascular reactivity (aTR) was lower in ESC /ESH grade I compared to those graded ACC/ASH stage I hypertension (p = 0.0122). The conclusion of this study is that microvascular dysfunctions is present at multiple levels only in individuals with ESC/ESH grade 1 hypertension. This observation could be important when deciding personalised care in individuals with early hypertensive changes.

    Time-resolved crystallography with X-ray free-electron lasers enables structural characterization of light-induced reactions on ultrafast timescales. To be biologically and chemically relevant, such studies must be carried out in an appropriate photoexcitation regime to avoid multiphoton artifacts, a common issue in recent studies. We describe numerical and experimental approaches to determine how many photons are needed for single-photon excitation in microcrystals, taking into account losses by scattering.

    在过去的十年里,化学和光子学的技术进步使得能够实时测量纳米级的温度。纳米温度计,专门设计用于传递这些纳米级温度变化的探头,提供高温度,temporal,空间分辨率和精度。已经提出了几种不同的方法,包括微热电偶,基于发光和荧光偏振各向异性的纳米温度计。基于各向异性的纳米温度计在生物相容性方面表现出色,因为它们可以由与染料共轭的内源性蛋白质构建而成,最小化任何系统扰动。此外,产生的荧光蛋白可以保留其天然结构和活性,同时进行温度测量,允许在任何给定的实验系统中从天然环境或酶促反应期间进行精确的温度记录。为了便于将来在研究中使用这些纳米温度计,在这里,我们提出了一个理论模型,可以预测从任何蛋白质或染料开始的基于各向异性的温度计的最佳灵敏度,基于蛋白质大小和染料荧光寿命。使用这个模型,大多数蛋白质和染料可以转化为纳米温度计。科学界广泛的学科使用这些纳米温度计将带来新的知识和理解,这些知识和理解今天仍然无法使用当前的技术。
    In the last decade, technological advances in chemistry and photonics have enabled real-time measurement of temperature at the nanoscale. Nanothermometers, probes specifically designed to relay these nanoscale temperature changes, provide a high degree of temperature, temporal, and spatial resolution and precision. Several different approaches have been proposed, including microthermocouples, luminescence and fluorescence polarization anisotropy-based nanothermometers. Anisotropy-based nanothermometers excel in terms of biocompatibility because they can be built from endogenous proteins conjugated to dyes, minimizing any system perturbation. Moreover, the resulting fluorescent proteins can retain their native structure and activity while performing the temperature measurement, allowing precise temperature recordings from the native environment or during an enzymatic reaction in any given experimental system. To facilitate the future use of these nanothermometers in research, here we present a theoretical model that predicts the optimal sensitivity for anisotropy-based thermometers starting with any protein or dye, based on protein size and dye fluorescence lifetime. Using this model, most proteins and dyes can be converted to nanothermometers. The utilization of these nanothermometers by a broad spectrum of disciplines within the scientific community will bring new knowledge and understanding that today remains unavailable with current techniques.

    在经尿道膀胱癌电切术中使用六胺乙酰丙酸酯(HAL)进行蓝光膀胱镜检查(BLC)可改善非肌层浸润性膀胱癌(NMIBC)的检测并降低复发率。FlexibleBLC于2018年被FDA批准用于监测环境,并被证明可以改善检测。蓝光柔性膀胱镜检查(BLFC)在中危和高危NMIBC监测中的III期前瞻性多中心研究结果表明,仅BLFC鉴定了20.6%的恶性肿瘤。通过减少未来的复发和更早地识别对治疗无反应的肿瘤,预计在监测环境中提高的检出率将导致改善的临床结果。因此,BLFC在膀胱镜检查中发挥作用,并确定哪些患者将受益于BLFC,必须开发将该技术纳入膀胱镜检查的最佳和具有成本效益的方法.
    Blue light cystoscopy (BLC) with hexaminolevulinate (HAL) during transurethral resection of bladder cancer improves detection of non-muscle-invasive bladder cancer (NMIBC) and reduces recurrence rates. Flexible BLC was approved by the FDA in 2018 for use in the surveillance setting and was demonstrated to improve detection. Results of a phase III prospective multicentre study of blue light flexible cystoscopy (BLFC) in surveillance of intermediate-risk and high-risk NMIBC showed that 20.6% of malignancies were identified only by BLFC. Improved detection rates in the surveillance setting are anticipated to lead to improved clinical outcomes by reducing future recurrences and earlier identification of tumours that are unresponsive to therapy. Thus, BLFC has a role in surveillance cystoscopy, and determining which patients will benefit from BLFC and optimal and cost-effective ways of incorporating this technology into surveillance cystoscopy must be developed.

    轮班工作没有普遍的标准定义,并且没有经过验证的关于工人轮班工作的完整生物学调整的报告。同样,由于研究数量少,结果测量范围狭窄,因此轮班工作容忍度的证据有限.本文讨论了迄今为止有关轮班工作容忍度个体差异的证据,并强调了未来研究的领域和工作场所实践的建议。与感知或实际轮班工作容忍度始终相关的少数因素是年轻年龄,低分的早熟或晚熟,低分的懒惰和神经质,外向性得分很高,内部控制源和灵活性和男性。重要的第一步是区分可能改变的因素,比如那些由生活方式选择决定的,以及工作时间安排特有的因素。确定轮班工作公差的决定因素和适应轮班工作的能力,无论它们是先天的和/或后天的机制,很重要,因此不太可能容忍轮班工作的工人可以自我识别,并通过适当的伤害/风险最小化策略来支持。本文还确定了未来研究的重要领域,目的是增加证据基础,我们可以在此基础上为轮班工人制定基于证据的伤害缓解策略。
    There is no standard definition of shift work universally, and no validated report of complete biological adjustment to shift work in workers. Similarly, the evidence for shift work tolerance is limited due to a small number of studies and a narrow range of outcome measures. This paper discusses evidence to date regarding individual differences in shift work tolerance and highlights areas for future research and recommendations for workplace practice. The few factors that are consistently associated with perceived or actual shift work tolerance are young age, low scores of morningness or being a late chronotype, low scores of languidity and neuroticism, high scores on extraversion, internal locus of control and flexibility and male sex. An important first step is to differentiate between factors that are potentially modifiable, such as those that are determined by lifestyle choices, and those factors specific to the working time arrangement. Identifying determinants of shift work tolerance and the ability to adjust to shift work, whether they are innate and/or acquired mechanisms, is important so workers who are less likely to tolerate shift work well can be self-identified and supported with appropriate harm/risk minimization strategies. This paper also identifies important areas for future research with the goal of increasing the evidence base on which we can develop evidence-based harm mitigation strategies for shift workers.

    Potential effects of shift work on health are probably related to the misalignment between the light-dark cycle and the human activity-rest cycle. Light exposure at night mediates these effects, including social misalignment and leads to an inversion of activity and rest, which, in turn, is linked to changes in behaviours. This article reviews the epidemiological evidence on the association between shift work and health, and possible mechanisms underlying this association. First, evidence from findings of the meta-analyses and systematic reviews published in the last 10 yr is presented. In addition, it reports the larger single-occupation studies and recent large population-based studies of the general workforce. Koch\'s postulates were used to evaluate the evidence related to the development of disease as a result of exposure to shift work. Finally, we discussed limitations of the multiple pathways that link shift work with specific disorders and the methodological challenges facing shift work research. We concluded that the clearest indications of shift work being the cause of a disease are given when there is a substantial body of evidence from high quality field studies showing an association and there is good evidence from laboratory studies supporting a causal explanation of the link.

    Traumatic scars not only affect local appearance and function, but also may be accompanied by pain, itching, and even psychological problems, which seriously affect the quality of patients\' life. The prevention and treatment of scars are still quite challengeable for plastic and cosmetic surgery. Recently, photoelectric therapy and radio-frequency technology have brought breakthroughs in the clinical prevention and treatment of traumatic scars due to the developments of theory and practice on selective photothermolysis and fractional photothermolysis. Based on the analysis and summary of experience of treatment of traumatic scars with photoelectric therapy and radiofrequency technology in the past 5 years, the experts in the Department of Plastic and Reconstructive Surgery of Shanghai Ninth People\'s Hospital of Shanghai Jiao Tong University School of Medicine, together with expert consensus on treatment of scar using laser at home and abroad, organize the experts in the field of scar management from different regions in China to discuss and write the consensus on treatment of skin traumatic scars with photoelectric therapy and radio-frequency technology (2018 version). This consensus is suitable for currently medical environment in China and aimed to provide standardized protocols for the treatment of skin traumatic scars in clinic.
