    This educational article explores the convergence of open science practices and traditional, complementary, and integrative medicine (TCIM), shedding light on the potential benefits and challenges of open science for the development, dissemination, and implementation of evidence-based TCIM. We emphasize the transformative shift in medical science towards open and collaborative practices, highlighting the limited application of open science in TCIM research despite its growing acceptance among patients. We define open science practices and discuss those that are applicable to TCIM, including: study registration; reporting guidelines; data, code and material sharing; preprinting; publishing open access; and reproducibility/replication studies. We explore the benefits of open science in TCIM, spanning improved research quality, increased public trust, accelerated innovation, and enhanced evidence-based decision-making. We also acknowledge challenges such as data privacy concerns, limited resources, and resistance to cultural change. We propose strategies to overcome these challenges, including ethical guidelines, education programs, funding advocacy, interdisciplinary dialogue, and patient engagement. Looking to the future, we envision the maturation of open science in TCIM, the development of TCIM-specific guidelines for open science practices, advancements in data sharing platforms, the integration of open data and artificial intelligence in TCIM research, and changes in the context of policy and regulation. We foresee a future where open science in TCIM leads to a better evidence base, informed decision-making, interdisciplinary collaboration, and transformative impacts on healthcare and research methodologies, highlighting the promising synergy between open science and TCIM for holistic, evidence-based healthcare solutions.

    Recent advances in open neuroimaging data are enhancing our comprehension of neuropsychiatric disorders. By pooling images from various cohorts, statistical power has increased, enabling the detection of subtle abnormalities and robust associations, and fostering new research methods. Global collaborations in imaging have furthered our knowledge of the neurobiological foundations of brain disorders and aided in imaging-based prediction for more targeted treatment. Large-scale magnetic resonance imaging initiatives are driving innovation in analytics and supporting generalizable psychiatric studies. We also emphasize the significant role of big data in understanding neural mechanisms and in the early identification and precise treatment of neuropsychiatric disorders. However, challenges such as data harmonization across different sites, privacy protection, and effective data sharing must be addressed. With proper governance and open science practices, we conclude with a projection of how large-scale imaging resources and collaborations could revolutionize diagnosis, treatment selection, and outcome prediction, contributing to optimal brain health.

    抗菌素耐药性(AMR)被广泛认为是全球面临的最严重的公共卫生威胁之一。然而,私营部门发现生产急需的药物具有挑战性。作为一种替代的发现方法,针对ESKAPE病原体筛选了一系列二芳基咪唑,结果通过开源抗生素(OSA)联盟(https://github.com/opensourceantistics)公开提供。在测试的18种化合物中(32μg/mL),图15显示针对单独的耐甲氧西林金黄色葡萄球菌(MRSA)的>90%的生长抑制活性。在随后对这种化学型的命中到铅优化中,合成了147个含有二芳基咪唑和其他核心基序的新杂环化合物,并对MRSA进行了测试,并确定了它们的结构-活动关系。虽然有效,这些化合物具有中等至高的内在清除率和一些相关的毒性。用OSA_975找到了最佳的参数总体平衡,该化合物具有良好的效力,良好的溶解性,并降低大鼠肝细胞的内在清除率。我们已经取得了对这些表型活性化合物的分子靶标的认识,蛋白质组学技术表明TGFBR1可能参与作用机制。根据该项目的许可条款,任何人都可以将这些化合物进一步开发为抗菌药物。
    Antimicrobial resistance (AMR) is widely acknowledged as one of the most serious public health threats facing the world, yet the private sector finds it challenging to generate much-needed medicines. As an alternative discovery approach, a small array of diarylimidazoles was screened against the ESKAPE pathogens, and the results were made publicly available through the Open Source Antibiotics (OSA) consortium (https://github.com/opensourceantibiotics). Of the 18 compounds tested (at 32 μg/mL), 15 showed >90% growth inhibition activity against methicillin-resistant Staphylococcus aureus (MRSA) alone. In the subsequent hit-to-lead optimization of this chemotype, 147 new heterocyclic compounds containing the diarylimidazole and other core motifs were synthesized and tested against MRSA, and their structure-activity relationships were identified. While potent, these compounds have moderate to high intrinsic clearance and some associated toxicity. The best overall balance of parameters was found with OSA_975, a compound with good potency, good solubility, and reduced intrinsic clearance in rat hepatocytes. We have progressed toward the knowledge of the molecular target of these phenotypically active compounds, with proteomic techniques suggesting TGFBR1 is potentially involved in the mechanism of action. Further development of these compounds toward antimicrobial medicines is available to anyone under the licensing terms of the project.

    跟踪测试B(TMT-B)指示认知灵活性和其他几个认知领域。以前的研究表明,它可能与发生术后谵妄的风险有关,但是证据是有限的和相互矛盾的。因此,我们旨在复制术前TMT-B结果与术后谵妄的关联。
    我们纳入了计划进行大手术且无痴呆征象的老年人(≥65岁)参与这项双中心纵向观察队列研究。获得术前TMT-B评分。使用经过验证的仪器每天两次评估谵妄。应用Logistic回归并计算受试者工作特征曲线下面积以确定TMT-B的预测性能。随后,我们纳入了先前研究中使用的协变量,用于连续的敏感性分析。我们进一步分析了异常值的影响,数据缺失或受损。
    纳入了841例患者的数据,151(18%)发生术后谵妄。TMT-B评分与术后谵妄的发生率有统计学意义{每10秒增加1.06的比值比(95%置信区间[CI]1.02-1.09),P=0.001}。受试者工作特征曲线下面积为0.60([95%CI0.55-0.64],P<0.001)。在删除21个异常值后,关联仍然存在(1.07[95%CI1.03-1.07],P<0.001)。受损或缺失的TMT-B数据(n=88)也与术后谵妄相关(比值比2.74[95%CI1.71-4.35],P<0.001)。
    TMT-B与术后谵妄有关,但它作为独立测试的预测性能很低。单独的TMT-B不适合在临床环境中预测谵妄。
    NCT02265263。(https://clinicaltrials.gov/ct2/show/results/NCT02265263)。
    UNASSIGNED: The Trail Making Test B (TMT-B) is indicative of cognitive flexibility and several other cognitive domains. Previous studies suggest that it might be associated with the risk of developing postoperative delirium, but evidence is limited and conflicting. We therefore aimed to replicate the association of preoperative TMT-B results with postoperative delirium.
    UNASSIGNED: We included older adults (≥65 yr) scheduled for major surgery and without signs of dementia to participate in this binational two-centre longitudinal observational cohort study. Presurgical TMT-B scores were obtained. Delirium was assessed twice daily using validated instruments. Logistic regression was applied and the area under the receiver operating characteristic curve calculated to determine the predictive performance of TMT-B. We subsequently included covariates used in previous studies for consecutive sensitivity analyses. We further analysed the impact of outliers, missing or impaired data.
    UNASSIGNED: Data from 841 patients were included and of those, 151 (18%) developed postoperative delirium. TMT-B scores were statistically significantly associated with the incidence of postoperative delirium {odds ratio per 10-s increment 1.06 (95% confidence interval [CI] 1.02-1.09), P=0.001}. The area under the receiver operating characteristic curve was 0.60 ([95% CI 0.55-0.64], P<0.001). The association persisted after removing 21 outliers (1.07 [95% CI 1.03-1.07], P<0.001). Impaired or missing TMT-B data (n=88) were also associated with postoperative delirium (odds ratio 2.74 [95% CI 1.71-4.35], P<0.001).
    UNASSIGNED: The TMT-B was associated with postoperative delirium, but its predictive performance as a stand-alone test was low. The TMT-B alone is not suitable to predict delirium in a clinical setting.
    UNASSIGNED: NCT02265263. (https://clinicaltrials.gov/ct2/show/results/NCT02265263).

    网络神经科学在神经影像学研究中的快速应用提供了有用的工具,可以通过绘制自发的大脑活动来了解内在大脑功能的个体差异。即内在功能网络神经科学(ifNN)。然而,在IFNN研究中应用的方法的可变性-关于节点定义,边缘构造,和图形测量-使直接比较结果变得困难,并且对于最终用户选择用于映射大脑网络中的个体差异的最佳策略也具有挑战性。这里,我们的目标是通过使用HumanConnectome项目的重测设计,系统地比较不同ifNN分析策略下个体差异的测量可靠性,为最佳ifNN实践提供基准。结果揭示了指导NN研究的四个基本原则:(1)使用全脑分割来定义网络节点,包括皮质下和小脑区域;(2)使用多个慢带中的自发大脑活动构建功能网络;(3)在个体水平上优化网络的拓扑经济性;(4)用整合和隔离的特定指标表征信息流。我们为未来的ifNN(https://ibraindata.com/research/ifNN)构建了可靠性评估的交互式在线资源。
    A rapidly emerging application of network neuroscience in neuroimaging studies has provided useful tools to understand individual differences in intrinsic brain function by mapping spontaneous brain activity, namely intrinsic functional network neuroscience (ifNN). However, the variability of methodologies applied across the ifNN studies-with respect to node definition, edge construction, and graph measurements-makes it difficult to directly compare findings and also challenging for end users to select the optimal strategies for mapping individual differences in brain networks. Here, we aim to provide a benchmark for best ifNN practices by systematically comparing the measurement reliability of individual differences under different ifNN analytical strategies using the test-retest design of the Human Connectome Project. The results uncovered four essential principles to guide ifNN studies: (1) use a whole brain parcellation to define network nodes, including subcortical and cerebellar regions; (2) construct functional networks using spontaneous brain activity in multiple slow bands; and (3) optimize topological economy of networks at individual level; and (4) characterize information flow with specific metrics of integration and segregation. We built an interactive online resource of reliability assessments for future ifNN (https://ibraindata.com/research/ifNN).

    生成人工智能(AI)包括大型语言模型(LLM),准备改变科学研究,使研究人员能够提高他们的研究生产力。本文介绍了如何在学术环境中使用LLM的指南,专注于他们独特的优势,通过科学哲学和认识论的视角的约束和含义。使用ChatGPT作为案例研究,我确定并阐述了有助于其有效性的三个属性-智力,多功能性和协作-伴随着制作有效提示的技巧,实际用例和在线生活资源(https://osf.io/8vpwu/)。接下来,我评估了生成人工智能的局限性及其对道德使用的影响,平等与教育。关于道德和负责任的使用,我从技术和认识论的角度认为,没有必要限制人工智能援助的范围或性质,前提是其使用是透明公开的。一个紧迫的挑战,然而,在于检测虚假研究,这可以通过拥抱开放的科学实践来缓解,例如透明的同行评审和共享数据,代码和材料。解决平等问题,我认为,虽然生成人工智能可能会促进一些人的平等,它可能同时加剧其他人的差距-这个问题在发展过程中具有潜在的重大但不清楚的后果。最后,我认为这对教育的影响,倡导积极参与LLM,培养学生的批判性思维和分析能力。该指南旨在赋予研究人员必要的知识和资源,以有效利用生成AI,同时导航其应用固有的复杂道德困境。
    Generative artificial intelligence (AI), including large language models (LLMs), is poised to transform scientific research, enabling researchers to elevate their research productivity. This article presents a how-to guide for employing LLMs in academic settings, focusing on their unique strengths, constraints and implications through the lens of philosophy of science and epistemology. Using ChatGPT as a case study, I identify and elaborate on three attributes contributing to its effectiveness-intelligence, versatility and collaboration-accompanied by tips on crafting effective prompts, practical use cases and a living resource online (https://osf.io/8vpwu/). Next, I evaluate the limitations of generative AI and its implications for ethical use, equality and education. Regarding ethical and responsible use, I argue from technical and epistemic standpoints that there is no need to restrict the scope or nature of AI assistance, provided that its use is transparently disclosed. A pressing challenge, however, lies in detecting fake research, which can be mitigated by embracing open science practices, such as transparent peer review and sharing data, code and materials. Addressing equality, I contend that while generative AI may promote equality for some, it may simultaneously exacerbate disparities for others-an issue with potentially significant yet unclear ramifications as it unfolds. Lastly, I consider the implications for education, advocating for active engagement with LLMs and cultivating students\' critical thinking and analytical skills. The how-to guide seeks to empower researchers with the knowledge and resources necessary to effectively harness generative AI while navigating the complex ethical dilemmas intrinsic to its application.

    多年来,期刊评价体系以影响指标为中心,导致评价结果不能反映期刊的学术创新。为了解决这个问题,本研究试图从衡量每篇期刊文章中断的角度构建期刊中断指数(JDI)。在实际研究中,我们首先基于Crossref开放DOI-to-DOI引文(COCI)的开放引文指数,测量了22种选定病毒学期刊的文章中断情况.然后,我们根据文章的绝对中断指数(DZ)计算了22种病毒学期刊的JDI。最后,我们对影响指标和破坏指标之间的差异和相关性以及破坏指标的评价效果进行了实证研究。研究结果表明:(1)基于中断指标和影响指标的期刊排名存在较大差异。在22种期刊中,12在JDI中排名高于5年累积影响因子(CIF5),PR6期刊索引(JIPR6)和学科领域平均百分位数(APSA)。两种指标对17种期刊的排名差异大于或等于5。(2)在期刊和论文层面,中断指标和影响指标之间存在中等相关性。JDI与CIF5、JIPR6和aPSA中度相关,相关系数分别为0.486、0.471和-0.448。DZ也与累积引文(CC)中度相关,具有6个分类的百分位排序(PR6)和主题区域百分位数(PSA),相关系数分别为0.593、0.575和-0.593。(3)与传统影响指标相比,期刊中断评估的结果与专家同行评审的评估结果更加一致。JDI在一定程度上反映了期刊的创新水平,有助于促进科技期刊创新评价。
    For many years, the journal evaluation system has been centered on impact indicators, resulting in evaluation results that do not reflect the academic innovation of journals. To solve this issue, this study attempts to construct the Journal Disruption Index (JDI) from the perspective of measuring the disruption of each journal article. In the actual study, we measured the disruption of articles of 22 selected virology journals based on the OpenCitations Index of Crossref open DOI-to-DOI citations (COCI) first. Then we calculated the JDI of 22 virology journals based on the absolute disruption index (DZ) of the articles. Finally, we conducted an empirical study on the differences and correlations between the impact indicators and disruption indicators as well as the evaluation effect of the disruption index. The results of the study show: (1) There are large differences in the ranking of journals based on disruption indicators and impact indicators. Among the 22 journals, 12 are ranked higher by JDI than Cumulative Impact Factor for 5 years (CIF5), the Journal Index for PR6 (JIPR6) and average Percentile in Subject Area (aPSA). The ranking difference of 17 journals between the two kinds of indicators is greater than or equal to 5. (2) There is a medium correlation between disruption indicators and impact indicators at the level of journals and papers. JDI is moderately correlated with CIF5, JIPR6 and aPSA, with correlation coefficients of 0.486, 0.471 and - 0.448, respectively. DZ was also moderately correlated with Cumulative Citation (CC), Percentile Ranking with 6 Classifications (PR6) and Percentile in Subject Area (PSA) with correlation coefficients of 0.593, 0.575 and - 0.593, respectively. (3) Compared with traditional impact indicators, the results of journal disruption evaluation are more consistent with the evaluation results of experts\' peer review. JDI reflects the innovation level of journals to a certain extent, which is helpful to promote the evaluation of innovation in sci-tech journals.

    近年来,科学界呼吁提高可信度,研究的稳健性和可重复性,以增加兴趣和促进公开透明的研究实践为特征。虽然取得了积极进展,缺乏考虑如何将这种方法嵌入本科和研究生研究培训中。具体来说,需要对研究整合开放和可重复科学如何影响学生成绩的文献进行批判性概述。在本文中,我们提供了有关将开放和可复制的奖学金整合到教学和学习中及其在学生中的相关成果的文献的第一个批判性审查。我们的评论强调了如何嵌入开放和可重复的奖学金似乎与(i)学生的科学素养(即学生对开放研究的理解,科学的消费和可转移技能的发展);(ii)学生参与(即学习的动机和参与,合作和参与开放研究)和(iii)学生对科学的态度(即对科学的信任和对研究结果的信心)。然而,我们的审查还确定了在教学研究中需要更强大和严格的方法,包括更多的教学实践的干预性和实验性评价。我们讨论了对教学和学习奖学金的影响。
    In recent years, the scientific community has called for improvements in the credibility, robustness and reproducibility of research, characterized by increased interest and promotion of open and transparent research practices. While progress has been positive, there is a lack of consideration about how this approach can be embedded into undergraduate and postgraduate research training. Specifically, a critical overview of the literature which investigates how integrating open and reproducible science may influence student outcomes is needed. In this paper, we provide the first critical review of literature surrounding the integration of open and reproducible scholarship into teaching and learning and its associated outcomes in students. Our review highlighted how embedding open and reproducible scholarship appears to be associated with (i) students\' scientific literacies (i.e. students\' understanding of open research, consumption of science and the development of transferable skills); (ii) student engagement (i.e. motivation and engagement with learning, collaboration and engagement in open research) and (iii) students\' attitudes towards science (i.e. trust in science and confidence in research findings). However, our review also identified a need for more robust and rigorous methods within pedagogical research, including more interventional and experimental evaluations of teaching practice. We discuss implications for teaching and learning scholarship.

    数据共享是开放科学(OS)的重要组成部分,越来越多的机构和期刊一直在执行开放数据(OD)政策。倡导OD有助于提高学术影响力,促进科学发现和发展,但是这样的主张没有得到很好的阐述。本研究以中国经济学期刊为例,探讨了OD政策对文章引用模式的细微差别影响。中国工业经济(CIE)是迄今为止第一个也是唯一一个采用强制性OD政策的中国社会科学期刊,要求所有已发表的文章共享原始数据和处理代码。我们使用文章级数据和差异差异(DID)方法来比较CIE和36种可比期刊上发表的文章的引用表现。首先,我们发现OD政策迅速增加了引用次数,在发表后的前四年,每篇文章平均分别获得0.25、1.19、0.86和0.44次引用。此外,我们还发现,OD政策的引文效益随着时间的推移而迅速下降,甚至在出版后的第五年变得消极。总之,这种不断变化的引文模式表明,OD政策可能是一把双刃剑,这可以快速提高引用性能,但同时加速文章的老化。

    Data sharing is an important part of open science (OS), and more and more institutions and journals have been enforcing open data (OD) policies. OD is advocated to help increase academic influences and promote scientific discovery and development, but such a proposition has not been elaborated on well. This study explores the nuanced effects of the OD policies on the citation pattern of articles by using the case of Chinese economics journals. China Industrial Economics (CIE) is the first and only Chinese social science journal so far to adopt a compulsory OD policy, requiring all published articles to share original data and processing codes. We use the article-level data and difference-in-differences (DID) approach to compare the citation performance of articles published in CIE and 36 comparable journals. Firstly, we find that the OD policy quickly increased the number of citations, and each article on average received 0.25, 1.19, 0.86, and 0.44 more citations in the first four years after publication respectively. Furthermore, we also found that the citation benefit of the OD policy rapidly decreased over time, and even became negative in the fifth year after publication. In conclusion, this changing citation pattern suggests that an OD policy can be double edged sword, which can quickly increase citation performance but simultaneously accelerate the aging of articles.
