In the evaluation of acupuncture effects in traditional Chinese medicine (TCM), the unclear interpretation of microscopic mechanisms and the difficulty in verifying acupoint specificity due to insufficient resolution of MRI (Magnetic Resonance Imaging) are the main reasons for the difficulty. This paper adopts 7T ultra-high field MRI combined with dynamic ASL (arterial spin labeling) technology, taking advantage of its high spatial resolution and quantitative blood perfusion imaging, to achieve dynamic visualization of microcirculation at acupuncture points in patients with ulcerative colitis. Ulcerative colitis is an ideal site to verify the feasibility of this method because its lesion site is clear and easy to correspond with the body surface acupoint. This paper establishes a high-resolution imaging protocol based on 7T magnetic resonance imaging, adopts 0.5mm spatial resolution, and optimizes scanning parameters to adapt to the microstructural imaging requirements of the acupoint area. This paper introduces pCASL (pseudo-continuous arterial spin labeling) technology, sets the labeling duration and perfusion delay time, captures the changes in perfusion volume before and after acupuncture over time, and obtains a dynamic perfusion sequence. This paper adopts umbilical moxibustion therapy, selects specific meridian acupoints, sets a standard acupuncture stimulation scheme (needle insertion depth, frequency, and needle retention time), and simultaneously performs MRI scanning to achieve real-time acupuncture imaging acquisition. The acquired multi-time point images can be rigidly registered and mapped with standard templates, the blood flow intensity change curve of the acupuncture-related area can be extracted, and the time-perfusion function can be constructed to analyze the local response pattern. The experimental results show that the ΔCBF (Delta Cerebral Blood Flow) of 7T-ASL at Shenque, Tianshu and Zhongwan are 0.15, 0.12 and 0.18 respectively, and it has high sensitivity in capturing tiny blood flow changes under sub-millimeter resolution. The SNR (Signal-to-Noise Ratio) at Shenque, Tianshu and Zhongwan are 22, 25 and 24 respectively, and the CNR (Contrast-to-Noise Ratio) is 6.2, 6.5 and 6.7 respectively, which has significant advantages in the spatial identification of sensitive areas of neural regulation and the identification of perfusion response. The average rising rate, peak time and recovery time in all acupoints were 2.44%/s, 7.2s and 11.5s respectively, and the acupuncture effect took effect faster in local areas.
在中医针灸疗效评价中,显微机制解释不清,且由于MRI(磁共振成像)分辨率不够难以验证穴位特异性,是造成评价困难的主要原因。本文采用7T超高场MRI结合动态ASL(动脉自旋标记)技术,利用其高空间分辨率和定量血液灌注成像的优势,实现溃疡性结肠炎患者穴位微循环的动态可视化。溃疡性结肠炎因其病变部位清晰,易于与体表穴位对应,是验证该方法可行性的理想部位。本文建立了基于7T磁共振成像的高分辨率成像方案,采用0.5mm空间分辨率,并优化扫描参数,以适应穴位区域的微结构成像要求。本文引入pCASL(伪连续动脉自旋标记)技术,设置标记时间和灌注延迟时间,捕捉针刺前后灌注量随时间的变化,得到动态灌注序列。本文采用脐灸疗法,选择特定经络穴位,设定标准针刺刺激方案(插针深度、频率、留针时间),同时进行MRI扫描,实现实时针刺成像采集。对获取的多时间点图像进行严格配准和标准模板映射,提取针灸相关区域血流强度变化曲线,构建时间灌注函数分析局部反应模式。实验结果表明,7T-ASL在神雀、天树和中湾的ΔCBF (Delta Cerebral Blood Flow)分别为0.15、0.12和0.18,在亚毫米分辨率下对微小血流变化的捕捉具有很高的灵敏度。神雀、天树和中湾的信噪比分别为22、25和24,CNR分别为6.2、6.5和6.7,在神经调节敏感区域的空间识别和灌注反应识别方面具有显著优势。各穴位的平均上升速率、峰值时间和恢复时间分别为2.44%/s、7.2s和11.5s,局部见效较快。

Prostate cancer remains one of the leading causes of cancer-related illness and death in men globally. Despite advancements in diagnostics and traditional therapies, significant challenges such as drug resistance, systemic toxicity, and restricted specificity persist in impeding successful management. In recent years, nanotechnology has emerged as a revolutionary method in cancer treatment, offering targeted drug delivery, enhanced bioavailability, and reduced off-target side effects. Eco-friendly or green-synthesized nanomaterials have gained significant attention due to their biocompatibility, sustainability, and reduced environmental impact. This review delineates the present state of prostate cancer treatment and the constraints of traditional pharmacological approaches. We subsequently investigate the burgeoning role of nanomedicine in addressing these difficulties, focusing specifically on eco-friendly nanomaterials synthesized from plant extracts, microbial systems, and natural polymers. These biosynthesized nanoparticles (NPs) provide dual benefits: medicinal effectiveness and diminished environmental impact, consistent with the tenets of green chemistry and sustainable medicine. Additionally, we examine diverse drug delivery systems employing green NPs for prostate cancer, including liposomes, polymeric NPs, and metal-based systems synthesized through environmentally friendly methods. Recent in vitro and in vivo research is rigorously examined to assess the clinical potential of these methodologies. The review identifies significant translational hurdles, such as large-scale repeatability, regulatory constraints, and stability concerns, while proposing potential future approaches to enhance the therapeutic application of eco-friendly nanomedicine in prostate cancer treatment.
前列腺癌仍然是全球男性癌症相关疾病和死亡的主要原因之一。尽管诊断和传统治疗方法取得了进步,但诸如耐药性、全身毒性和限制性特异性等重大挑战仍然阻碍着成功的治疗。近年来,纳米技术已成为癌症治疗的一种革命性方法,提供靶向药物输送,提高生物利用度,减少脱靶副作用。生态友好型或绿色合成的纳米材料因其生物相容性、可持续性和减少对环境的影响而受到广泛关注。本文综述了前列腺癌治疗的现状和传统药理学方法的局限性。我们随后研究了纳米医学在解决这些困难方面的新兴作用,特别关注从植物提取物、微生物系统和天然聚合物合成的环保纳米材料。这些生物合成纳米颗粒(NPs)提供了双重好处:药物有效性和减少对环境的影响,符合绿色化学和可持续医学的原则。此外,我们研究了多种采用绿色NPs治疗前列腺癌的药物输送系统,包括脂质体、聚合物NPs和通过环保方法合成的金属基系统。最近的体外和体内研究经过严格检查,以评估这些方法的临床潜力。这篇综述指出了重大的转化障碍,如大规模的可重复性、监管限制和稳定性问题,同时提出了潜在的未来方法来加强生态友好型纳米药物在前列腺癌治疗中的治疗应用。

In the study of bone density changes and sports injury rehabilitation, traditional image processing technology lacks accuracy in analysis, rehabilitation assessment methods lack quantitative and systematic analysis, and interdisciplinary comprehensive evaluation is lacking. This paper constructs an innovative cognitive assessment model that combines bone density changes, sports injury rehabilitation, and high-resolution medical image analysis. It uses high-resolution CT (Computed Tomography) images and X-ray images to extract bone density data. It uses image processing technology to remove noise, enhance, and standardize, providing accurate bone density values for subsequent input. GCN (Graph Convolutional Network) can be used to automatically identify and classify images of sports injury sites, extract features of the injured area, record and analyze the patient's physical activities during the rehabilitation stage, and evaluate the recovery process of sports injuries in real time. Combining bone density data with sports injury imaging features, XGBoost (Extreme Gradient Boosting) is used to build a cognitive evaluation model, which conducts a comprehensive analysis of multi-dimensional data and provides personalized rehabilitation evaluation. It can integrate technologies from fields such as medicine, engineering, and computer science to establish an interdisciplinary comprehensive evaluation system, achieve multi-angle and multi-dimensional analysis, and ensure the comprehensiveness and accuracy of the model. The experimental results show that the MAE (Mean Absolute Error) of the GCN in this paper is 0.131 in 10 different injury sites, and the average MSE (Mean Squared Error) is about 0.032, which has higher image analysis accuracy. The average accuracy and R² of XGBoost in six different samples are about 0.87 and 0.91, respectively, and the prediction effect of the cognitive evaluation model is apparent.

In an era of increasingly stringent regulatory requirements and growing demands on laboratories in terms of data quality, integrity and reproducibility, combined with increasing sample throughput, digitization of the laboratory environment is an important tool to meet these growing demands. Unfortunately, many challenges stand in the way. Not only are these barriers difficult to overcome, but they also cut across the different professions that are essential to any digitization effort. For most laboratories, however, the simple question remains: How to transform an existing laboratory? This article proposes a structured method to realize the SmartLab and to verify its feasibility in practice, using a real R&D process. Consequently, on a qualitative level, not only has data integrity and sample traceability been enhanced, but standardization has also been increased. Quantitatively, the walk-away time was tripled and the efficiency of individual process steps was increased by over 20%. The project’s success can be attributed to the implementation of a systematic methodology for digital transformation, which functioned as a comprehensive guide, facilitating the execution of the project in a step-by-step manner.
在监管要求日益严格,对实验室在数据质量、完整性和可重复性方面的要求越来越高的时代,结合不断增加的样品吞吐量,实验室环境的数字化是满足这些日益增长的需求的重要工具。不幸的是,这条路上有许多挑战。这些障碍不仅难以克服,而且还跨越了对任何数字化努力都至关重要的不同职业。然而,对于大多数实验室来说,仍然存在一个简单的问题:如何改造现有的实验室?本文提出了一种结构化的方法来实现SmartLab,并通过一个真实的研发过程来验证其在实践中的可行性。因此,在质量层面上,不仅数据的完整性和样本的可追溯性得到了提高,而且标准化也得到了提高。从数量上讲,离开时间增加了三倍,单个工艺步骤的效率提高了20%以上。该项目的成功可归功于数字化转型的系统方法的实施,该方法作为全面的指南,以循序渐进的方式促进了项目的执行。

Environmental chemical exposure, such as pesticides and heavy metals, may contribute to neurodegenerative disorders through neuroinflammation. This study aims to identify suitable in vitro microglial models for assessing cytokine responses to potential neurotoxicants, particularly focusing on human induced pluripotent stem cell-derived microglia (hiMG). In this study, we evaluated the cytokine secretion profiles of four microglial cell types—hiMG, HMC3, IM-HM, and BV2—upon stimulation with lipopolysaccharides (LPS) using cytokine arrays. Our findings showed cytokine response patterns in hiMG cells that most closely resemble in vivo conditions, with significant increases in interleukin 6 (IL-6) and tumor necrosis factor-alpha (TNF-α) levels, the latter being uniquely expressed after LPS treatment. Consequently, we developed a homogeneous time-resolved fluorescence (HTRF) assay platform in a 1536-well plate format for high-throughput screening of environmental chemicals using hiMG cells. After LPS treatment, the assay window for secretion of IL-6 and TNF-α increased 3.71-fold and 2.62-fold over the vehicle control group, respectively, with respective EC50 values of approximately 50 ng/mL and 90 ng/mL for IL-6 and TNF-α. We also assessed the response activity of hiMG to other stimuli, including interferon gamma and various catecholamine compounds, and nine environmental chemicals with evidence of cytokine-inducing potential in other in vitro assays. While all nine tested agents stimulated IL-6 and TNF-α production, three compounds (e.g., picoxystrobin) showed significant stimulation of both cytokines. ​This study establishes a reliable high-throughput platform for detecting inflammatory effects of environmental toxicants in a microglial cell assay, contributing valuable insights into their neuroinflammatory potential and possible implications for neurodegenerative disorders.
环境中的化学物质暴露,如杀虫剂和重金属,可能通过神经炎症导致神经退行性疾病。本研究旨在确定合适的体外小胶质细胞模型,以评估细胞因子对潜在神经毒物的反应,特别是关注人诱导多能干细胞来源的小胶质细胞(hiMG)。在这项研究中,我们使用细胞因子阵列评估了四种小胶质细胞类型(himg, HMC3, IM-HM和bv2)在脂多糖(LPS)刺激下的细胞因子分泌谱。我们的研究结果显示,细胞因子在hiMG细胞中的反应模式与体内条件最相似,白细胞介素6 (IL-6)和肿瘤坏死因子α (TNF-α)水平显著升高,后者在LPS处理后唯一表达。因此,我们开发了1536孔板格式的均匀时间分辨荧光(htf)检测平台,用于使用hiMG细胞进行高通量筛选环境化学物质。LPS处理后,IL-6和TNF-α分泌的测定窗口分别比对照增加了3.71倍和2.62倍,IL-6和TNF-α的EC50值分别约为50 ng/mL和90 ng/mL。我们还评估了hiMG对其他刺激的反应活性,包括干扰素γ和各种儿茶酚胺化合物,以及在其他体外实验中具有细胞因子诱导潜力的九种环境化学物质。虽然所有九种被测试的药物都能刺激IL-6和TNF-α的产生,但三种化合物(如皮氧嘧啶)对这两种细胞因子都有显著的刺激作用。本研究建立了一个可靠的高通量平台,用于在小胶质细胞试验中检测环境毒物的炎症效应,为其神经炎症潜力和神经退行性疾病的可能含义提供了有价值的见解。

Polycystic Ovary Syndrome (PCOS) patients often have ovarian microcirculatory disorders. Traditional color Doppler imaging of microvascular is not sensitive enough and is prone to missed detection or artifact interference. This study is based on a high-frequency probe combined with SMI (Superb Microvascular Imaging) and ultrasound contrast imaging to achieve high signal-to-noise ratio acquisition and dynamic quantification of low-speed blood flow in microvascular, filling the gap in existing technology. This study sets low-pass filtering and low PRF (Pulse Repetition Frequency) to enhance the detection of low-speed flow signals in microvascular. SMI and CEUS (Contrast-Enhanced Ultrasound) sequences are collected in sequence, and the time points are calibrated synchronously on the same section to achieve multimodal image fusion. The ovarian area is semi-automatically segmented based on the U-Net model, and the ROI (Region of Interest) containing the vascular structure is extracted. The vascular density, average diameter, and number of branches are calculated using self-developed image analysis software, and the feature vector is derived. The CEUS time-intensity curve is fitted with a double exponential, and dynamic perfusion parameters such as peak time and perfusion half-life are extracted for microcirculation evaluation and hemodynamic analysis.

The perfusion half-life is distributed between 21.8 and 25.1 s, and the peak time of the PCOS group is delayed by 0.5 s compared with the normal group, indicating that there are significant differences in their microvascular structure and perfusion function.
多囊卵巢综合征(PCOS)患者常伴有卵巢微循环障碍。传统的彩色多普勒微血管成像灵敏度不高,容易漏检或人为干扰。本研究基于高频探头结合SMI (Superb Microvascular Imaging)和超声对比成像,实现微血管低速血流的高信噪比采集和动态量化,填补了现有技术的空白。本研究通过低通滤波和低PRF(脉冲重复频率)来增强微血管低速血流信号的检测。按顺序采集SMI和CEUS (Contrast-Enhanced Ultrasound)序列,在同一切片上同步标定时间点,实现多模态图像融合。基于U-Net模型对卵巢区域进行半自动分割,提取包含血管结构的感兴趣区域(ROI)。利用自主开发的图像分析软件计算血管密度、平均直径和分支数,并导出特征向量。采用双指数拟合超声造影时间-强度曲线,提取峰值时间、灌注半衰期等动态灌注参数,用于微循环评价和血流动力学分析。实验表明,在分析的10个卵巢roi中,血管密度范围为5.43% ~ 8.45%;平均直径为5.88 ~ 6.52像素;分支号码一致性差率小于3%。灌注半衰期分布在21.8 ~ 25.1秒之间,PCOS组峰值时间较正常组延迟0.5秒,说明两者微血管结构和灌注功能存在显著差异。

Objective

To establish and validate the radiomics model of carotid vulnerable plaque.

Methods

182 patients who underwent carotid endarterectomy in the First Affiliated Hospital of Soochow University from January 2019 to June 2022 were retrospectively analyzed. Plaque ultrasound images were acquired and segmented, and features were extracted using the R package “EBImage”. Six machine learning algorithms were used to construct a plaque vulnerability classifier model. The relationship between clinical biomarkers and outcomes was evaluated using linear regression and the False Discovery Rate (FDR) correction method.

Results

Diabetes, neutrophils, monocytes, high-sensitivity C-reactive protein, high-density lipoprotein, and stenosis rate were found to have a strong association with plaque vulnerability. The Naive Bayes algorithm performed well in the training set using image features alone, with an AUC of 0.840, and an AUC of 0.762 in the test set. The Decision Tree algorithm had certain performance in the training set using image features alone, with an AUC of 0.609, and an AUC of 0.626 in the test set. The Naive Bayes algorithm achieved excellent performance in the training set using both plaque ultrasound imaging features and clinical laboratory indicators, with an AUC of 0.922, and an AUC of 0.928 in the test set.

Conclusion

The above radiomics model can be used to predict the vulnerable carotid plaque before surgery. By combining plaque ultrasound imaging with clinical blood biomarkers, a more comprehensive and accurate assessment of plaque vulnerability can be achieved, thereby reducing the risk of cardiovascular events.

Despite significant advances in instrumentation and robotics, the automation of cell staining in flow cytometry remains largely unaddressed. While sample acquisition in flow cytometry has been fully automated, sample staining continues to be a predominantly manual process—requiring substantial time, labor, and cost. Additionally, the repetitive nature of manual staining introduces monotony and increases the likelihood of human error. The Staining Triad presented here achieves full automation of the staining process, requiring only the input of samples and reagents, with no manual intervention. Staining performed using the Staining Triad showed a comparable biomarker profile to that of conventional manual staining. The modular and adaptable system design enables the flexibility to tailor throughput and accommodate assay-specific requirements, thereby extending its applicability to plate-based ligand binding assays. Moreover, the system eliminates the need for pipette tips, exemplifying a sophisticated and sustainable solution that enhances laboratory efficiency while reducing human error and the primary source of plastic waste in flow cytometry staining. Although 3R initiatives (Reduce, Reuse, Recycle) have helped decrease laboratory plastic waste volumes, substantial amounts are still incinerated or end up in landfills, where they persist in the environment for decades. This limitation underscores the need to incorporate a fourth R—"Remove/Replace"—into sustainability strategies. As flow cytometry becomes increasingly integral across various biotechnology disciplines, it is imperative to streamline associated workflows to accelerate drug discovery while preserving the environment that sustains life.
尽管在仪器和机器人技术方面取得了重大进展,但流式细胞术中细胞染色的自动化在很大程度上仍未得到解决。虽然流式细胞术中的样品采集已经完全自动化,但样品染色仍然是一个主要的人工过程-需要大量的时间,劳动力和成本。此外,手工染色的重复性引入了单调性,增加了人为错误的可能性。这里介绍的染色三合一实现了染色过程的完全自动化,只需要输入样品和试剂,无需人工干预。使用染色三合一进行的染色显示出与传统手工染色相当的生物标志物特征。模块化和适应性强的系统设计提供了灵活性,以定制吞吐量和适应分析特定的要求,从而扩展其适用于基于板的配体结合分析。此外,该系统消除了对移液头的需求,体现了一个复杂和可持续的解决方案,提高了实验室效率,同时减少了人为错误和流式细胞术染色中塑料废物的主要来源。尽管3R倡议(减少、再利用、再循环)帮助减少了实验室塑料废物的数量,但仍有大量塑料被焚烧或最终进入垃圾填埋场,在那里它们在环境中存留了几十年。这一限制强调了将第四个R——“移除/替换”——纳入可持续发展战略的必要性。随着流式细胞术在各种生物技术学科中越来越不可或缺,简化相关工作流程以加速药物发现,同时保护维持生命的环境势在必行。

Background

Bronchopleural fistula (BPF) is a common and severe complication in thoracic surgery, characterized by its complex nature and high mortality rate. Bronchial occluder is one of the effective methods for the interventional treatment of BPF under bronchoscopy.

Objective

This work was to evaluate the adoption and efficacy of individualized bronchial occluder designed with the assistance of 3D printing technology in the treatment of BPF.

Material and Methods

This single-center, retrospective study included 60 patients (35 males and 25 females, aged 40–78 years, without severe dysfunction of major organs or history of mental disorders) diagnosed with BPF between January 2020 and December 2023, who received different treatment and were divided into the Control Group (CG, receiving thoracotomy treatment), Therapy group-I (TG-I, receiving septal occluder treatment), and Therapy group-II (TG-II, receiving treatment with 3D-printed individualized bronchial occluder). Serum levels of high-sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) were measured by enzyme-linked immunosorbent assay preoperatively and at 1, 4, and 12 weeks postoperatively. Daytime cough scores were assessed according to guidelines, pain scores were evaluated using a visual analog scale, clinical efficacy was determined based on consensus criteria, and complications were recorded. Quantitative variables were compared using one-way ANOVA with Bonferroni correction, while categorical variables were analyzed by chi-square or Fisher’s exact test.

Results

the overall clinical efficacy was higher in TG-I and TG-II versus CG, with TG-II showing a greatly higher efficacy after twelve weeks of treatment (P < 0.05). Relative to CG, both TG-I and TG-II demonstrated lower serum levels of hs-CRP and PCT, markedly reduced cough and pain symptom scores, and markedly lower complication rates (P < 0.05). Additionally, TG-II resulted in notably lower serum inflammatory markers, cough and pain symptom scores, and complication rates versus TG-I (P < 0.05).

Conclusion

The 3D-printed personalized occluder (TG-II) significantly reduced postoperative inflammatory responses and alleviated cough-associated pain, demonstrating superior short-term efficacy and safety compared to conventional treatment (CG) and commercially available occluders (TG-I). This approach offers distinct advantages for the personalized precision treatment of BPF. However, further clinical studies are required to validate its potential as an alternative to surgical repair.
背景:支气管胸膜瘘(BPF)是胸外科手术中常见且严重的并发症,其性质复杂,死亡率高。支气管闭塞术是支气管镜下介入治疗BPF的有效方法之一。目的:评价3D打印技术辅助设计的个体化支气管封堵器在BPF治疗中的应用及疗效。材料和方法:本单中心回顾性研究纳入2020年1月至2023年12月诊断为BPF的患者60例(男35例,女25例,年龄40-78岁,无严重主要器官功能障碍或精神障碍史),接受不同治疗,分为对照组(CG,接受开胸治疗)、治疗组i (TG-I,接受间隔闭塞治疗)和治疗组ii (TG-II,接受3d打印个性化支气管封堵器治疗)。术前、术后1、4、12周采用酶联免疫吸附法测定血清高敏c反应蛋白(hs-CRP)和降钙素原(PCT)水平。根据指南评估日间咳嗽评分,使用视觉模拟量表评估疼痛评分,根据共识标准确定临床疗效,并记录并发症。定量变量比较采用Bonferroni校正的单因素方差分析,分类变量分析采用卡方或Fisher精确检验。结果:与CG相比,TG-I和TG-II的总体临床疗效更高,其中TG-II在治疗12周后的疗效明显更高(p结论:3d打印个性化封口器(TG-II)显著降低了术后炎症反应,缓解了咳嗽相关疼痛,与常规治疗(CG)和市售封口器(TG-I)相比,具有更优越的短期疗效和安全性。这种方法为BPF的个性化精确治疗提供了明显的优势。然而,需要进一步的临床研究来验证其作为手术修复替代方案的潜力。
