    BACKGROUND: Intensive care unit-acquired weakness (ICU-AW) is very common in ICU patients. It is important to understand the status quo of knowledge, attitude and behavior of ICU nurses about ICU-AW. This survey aimed to investigate the knowledge, attitude and behavior of ICU nurses about ICU-AW, to provide useful implications for clinical care.
    METHODS: ICU nurses from two tertiary hospitals in China from October 10 to November 15, 2023 were included. The ICU-AW knowledge, attitude and behavior questionnaire of ICU nurses with 31 items were used for survey. SPSS24.0 statistical software was used for data analysis.
    RESULTS: A total of 364 ICU nurses were included for survey. The ICU-AW knowledge of ICU nurses was 21.96 ± 5.72 (< 50% of the total knowledge score), the ICU-AW attitude of ICU nurses was 30.24 ± 5.05(< 75% of the total attitude score), the ICU-AW behavior of ICU nurses was 26.77 ± 5.81(< 75% of the total behavior score), the total score was 79.21 ± 12.69(< 75% of the total score). Nurses\' ICU-AW knowledge, attitude and behavior were all correlated (all P < 0.05). Multiple linear regression analyses indicated that age, years of ICU work experience, professional ranks and titles, had received the training about the ICU-AW were the influencing factors of knowledge, attitude and behavior of ICU nurses about ICU-AW (all P < 0.05).
    CONCLUSIONS: The knowledge, attitude and behavior of ICU nurses\' ICU-AW needs to be improved, and there are many influencing factors. Hospital nursing administrators should strengthen the training of nurses\' ICU-AW knowledge and improve the cognitive and practical ability of ICU nurses on ICU-AW, so as to reduce the occurrence of ICU-AW.

    The spatiotemporal heterogeneity of neurons, circuits and regulators is being uncovered at a single-cell level, from single-cell gene expression to functional regulations. The classifications, architectonics and functional communications amongst neural cells and circuits within the brain can be clearly delineated using single-cell multiomics and transomics. This Editorial highlights the spatiotemporal heterogeneity of neurons and circuits as well as regulators, initiates the translation of neuronal diversity and spatial organisation at single-cell levels into clinical considerations, and enables the discovery and development of new therapies for neurological diseases. It is predicted that single-cell and spatial multiomics will be integrated with metabolomic profiles and corresponding gene epigenetic modifications. The interactions amongst DNAs, RNAs and proteins in a cell provide details of intracellular functional regulations and new opportunities for the translation of temporospatial diversity of neural cell subtypes/states into clinical practice. The application of single-cell multiomics with four-dimensional genome to the human pathological brain will lead us to a new milestone of the diagnosis and treatment.

    多形性胶质母细胞瘤(GBM)是神经胶质瘤的最侵袭性形式,也是中枢神经系统最常见的原发性肿瘤。尽管近年来GBM的临床管理策略和诊断技术取得了重大进展,它仍然是一种致命的疾病。目前的护理标准包括手术,辐射,和化疗,但患者的5年生存率低于5%。寻求更精确的诊断和早期干预仍然是临床实践中一个关键和紧迫的挑战。Notch信号通路是重要的信号传导系统,在胶质母细胞瘤的恶性进展中被广泛研究。这种高度保守的信号级联是各种生物过程的核心,包括增长,扩散,自我更新,迁移,凋亡,和新陈代谢。在GBM中,不断积累的数据表明,Notch信号通路是过度活跃的,并有助于GBM的启动,programming,和治疗阻力。本文综述了Notch信号通路在GBM中的生物学功能和分子机制。以及针对Notch信号通路在癌症和胶质母细胞瘤中的一些临床进展,强调其作为新型治疗策略重点的潜力。
    Glioblastoma multiforme (GBM) is the most aggressive form of glioma and the most common primary tumor of the central nervous system. Despite significant advances in clinical management strategies and diagnostic techniques for GBM in recent years, it remains a fatal disease. The current standard of care includes surgery, radiation, and chemotherapy, but the five-year survival rate for patients is less than 5%. The search for a more precise diagnosis and earlier intervention remains a critical and urgent challenge in clinical practice. The Notch signaling pathway is a critical signaling system that has been extensively studied in the malignant progression of glioblastoma. This highly conserved signaling cascade is central to a variety of biological processes, including growth, proliferation, self-renewal, migration, apoptosis, and metabolism. In GBM, accumulating data suggest that the Notch signaling pathway is hyperactive and contributes to GBM initiation, progression, and treatment resistance. This review summarizes the biological functions and molecular mechanisms of the Notch signaling pathway in GBM, as well as some clinical advances targeting the Notch signaling pathway in cancer and glioblastoma, highlighting its potential as a focus for novel therapeutic strategies.

    Keap1-Nrf2信号通路是细胞保护反应的主要调节因子,参与由ROS(活性氧)引起的内源性和外源性胁迫。Nrf2是该途径的核心。本文对Keap1-Nrf2信号通路的相关文献进行了综述,总结了以下三个方面:功能通路,以及肿瘤和临床应用现状。这一信号通路类似于一把双刃剑:一方面,Nrf2活性可以保护细胞免受氧化和亲电应激;另一方面,增加Nrf2活性可以增强癌细胞的存活和增殖。值得注意的是,氧化应激也被认为是人类癌症的标志物。Keap1-Nrf2信号通路,作为一种典型的抗氧化应激途径,在多种人类恶性肿瘤疾病(如肺癌、肝癌,和甲状腺癌)。近年来,Keap1-Nrf2信号通路的研究日益深入和细致。因此,探讨该通路发生发展的分子机制对肿瘤防治具有重要意义。
    The Keap1-Nrf2 signaling pathway is a major regulator of the cytoprotective response, participating in endogenous and exogenous stress caused by ROS (reactive oxygen species). Nrf2 is the core of this pathway. We summarized the literature on Keap1-Nrf2 signaling pathway and summarized the following three aspects: structure, function pathway, and cancer and clinical application status. This signaling pathway is similar to a double-edged sword: on the one hand, Nrf2 activity can protect cells from oxidative and electrophilic stress; on the other hand, increasing Nrf2 activity can enhance the survival and proliferation of cancer cells. Notably, oxidative stress is also considered a marker of cancer in humans. Keap1-Nrf2 signaling pathway, as a typical antioxidant stress pathway, is abnormal in a variety of human malignant tumor diseases (such as lung cancer, liver cancer, and thyroid cancer). In recent years, research on the Keap1-Nrf2 signaling pathway has become increasingly in-depth and detailed. Therefore, it is of great significance for cancer prevention and treatment to explore the molecular mechanism of the occurrence and development of this pathway.

    脓毒症是全球第三大死亡原因。抗生素是治疗脓毒症的重要组成部分。抗生素的使用目前面临着增加抗生素抗性的挑战(Evans等人。,2021)。脓毒症药物预测可以建模为马尔可夫决策过程,但是现有的方法无法与医学知识相结合,使决策过程可能偏离医学常识,导致业绩不佳。(Wang等人。,2021)。在本文中,我们使用深度Q-Network(DQN)构建脓毒症抗感染DQN(SAI-DQN)模型,以解决在脓毒症治疗中确定抗生素的最佳组合和持续时间这一难题.通过将败血症临床知识设置为奖励功能,以指导DQN遵守医学指南,我们为抗生素联合用药制定了个性化治疗建议.结果表明,我们的模型比临床决策具有更高的决策平均值。对于患者的测试集,我们的模型预测,79.07%的患者使用推荐的抗生素组合将获得良好的预后.通过统计分析决策轨迹和药物作用选择,我们的模型能够提供符合临床实践的合理用药建议.我们的模型能够通过根据某些临床知识推荐适当的抗生素组合来改善患者的预后。
    Sepsis is the third leading cause of death worldwide. Antibiotics are an important component in the treatment of sepsis. The use of antibiotics is currently facing the challenge of increasing antibiotic resistance (Evans et al., 2021). Sepsis medication prediction can be modeled as a Markov decision process, but existing methods fail to integrate with medical knowledge, making the decision process potentially deviate from medical common sense and leading to underperformance. (Wang et al., 2021). In this paper, we use Deep Q-Network (DQN) to construct a Sepsis Anti-infection DQN (SAI-DQN) model to address the challenge of determining the optimal combination and duration of antibiotics in sepsis treatment. By setting sepsis clinical knowledge as reward functions to guide DQN complying with medical guidelines, we formed personalized treatment recommendations for antibiotic combinations. The results showed that our model had a higher average value for decision-making than clinical decisions. For the test set of patients, our model predicts that 79.07% of patients will achieve a favorable prognosis with the recommended combination of antibiotics. By statistically analyzing decision trajectories and drug action selection, our model was able to provide reasonable medication recommendations that comply with clinical practices. Our model was able to improve patient outcomes by recommending appropriate antibiotic combinations in line with certain clinical knowledge.
