Objective

This study aims to assess the effectiveness of quantitative electroencephalography (qEEG) in determining the prognosis of acute ischemic stroke, thus offering a scientific foundation for early prognostic evaluation.

Methods

One hundred sixty-seven patients with acute ischemic stroke were admitted to the Neurology Department of Hebei Provincial People's Hospital between May 2022 and October 2023. All patients received standard treatments, including antiplatelet aggregation and lipid-lowering therapy to stabilize plaques. EEG data, mRS scores after three months, NIHSS scores before treatment, and basic patient information were all documented. Patients with a poor prognosis (mRS > 3) and those with a good prognosis (mRS < 3) were separated into two groups. The impact of EEG parameters on stroke prognosis was assessed. These indices included relative Alpha power (RAP), relative beta power (RBP), relative Theta power (RTP), relative Delta power (RDP), (δ+θ)/(α+β) value (DTABR), δ/θ value (DTR), α/β value (ABR), δ/α value (DAR), and α/(θ+δ) value (ATDR).

Results

RAP, RTP, RDP, DTABR, DTR, ABR, DAR, and ATDR were significantly correlated with mRS scores after three months. Univariate logistic regression analysis of the groups with good and poor prognoses revealed that NIHSS scores and EEG parameters, including α %, θ %, δ %, DTABR, ABR, DAR, and ATDR, were associated with functional outcomes. Following adjustment for NIHSS scores, multivariate logistic regression identified DTABR and DAR as predictors of functional outcomes. The optimal threshold for DTABR was 0.810, yielding a sensitivity of 0.848 and specificity of 0.864, while the cutoff value for DAR was 0.665, with a sensitivity of 0.759 and specificity of 0.955, as determined by ROC curve analysis assessing the sensitivity and specificity of DTABR and DAR in forecasting poor prognosis.

Conclusion

This study confirmed that NIHSS scores are reliable indicators of stroke severity for prognosis prediction. After accounting for NIHSS scores, it was further established that EEG indices could predict functional outcomes three months post-acute ischemic stroke, with DTABR and DAR demonstrating high sensitivity and specificity.
目的:探讨定量脑电图(qEEG)在判断急性缺血性脑卒中预后中的作用,为早期预后评估提供科学依据。方法:选取2022年5月至2023年10月河北省人民医院神经内科收治的急性缺血性脑卒中患者167例。所有患者均接受标准治疗,包括抗血小板聚集和降脂治疗以稳定斑块。记录脑电图、治疗后3个月mRS评分、治疗前NIHSS评分及患者基本信息。预后差(mRS < 3)和预后好(mRS < 3)患者分为两组。评估脑电图参数对脑卒中预后的影响。这些指标包括相对α功率(RAP)、相对β功率(RBP)、相对θ功率(RTP)、相对δ功率(RDP)、(δ+θ)/(α+β)值(DTABR)、δ/θ值(DTR)、α/β值(ABR)、δ/α值(DAR)和α/(θ+δ)值(ATDR)。结果:3个月后,RAP、RTP、RDP、DTABR、DTR、ABR、DAR、ATDR与mRS评分显著相关。单因素logistic回归分析显示,NIHSS评分和脑电图参数(包括α%、θ%、δ%、DTABR、ABR、DAR和ATDR)与功能结局相关。调整NIHSS评分后,多变量逻辑回归确定DTABR和DAR为功能结局的预测因子。DTABR的最佳阈值为0.810,敏感性为0.848,特异性为0.864;DAR的截止值为0.665,敏感性为0.759,特异性为0.955,通过ROC曲线分析评估DTABR和DAR预测不良预后的敏感性和特异性。结论:本研究证实NIHSS评分是预测脑卒中严重程度的可靠指标。考虑NIHSS评分后,进一步证实脑电图指标可以预测急性缺血性脑卒中后3个月的功能结局,其中DTABR和DAR具有较高的敏感性和特异性。

Objective

Endothelial dysfunction is implicated in the pathogenesis of ischemic stroke (IS), but its causal role remains unclear. This study systematically investigates the causal relationship between endothelial dysfunction proteins and IS and its subtypes through integrated observational and genetic evidence.

Methods

A two-stage study was conducted combining systematic meta-analysis and Mendelian randomization (MR). The meta-analysis integrated data from 29 observational studies to assess associations between endothelial dysfunction proteins (vWF, sE-selectin, sP-selectin, ICAM-1, VCAM-1, sLOX-1, VEGF, ET-1, SDF-1) and IS. This meta-analysis was registered online (PROSPERO ID: CRD42023461783). Subsequent MR was applied to discern the causal effects of the endothelial dysfunction proteins on IS and its subtypes, utilizing genetically instrumental variants.

Results

A meta-analysis demonstrated significant correlations with IS for vWF, sE-selectin, ICAM-1, sP-selectin, sLOX-1, and VEGF (all p < 0.05). Furthermore, MR analysis showed that genetically elevated vWF increased the risk for any IS and cardioembolic stroke (CES), while E-selectin was causally linked to large-artery atherosclerosis stroke (LAS).

Conclusion

This work offers causal evidence that endothelial dysfunction significantly contributes to IS, highlighting the thrombotic activity of vWF in CES and the inflammatory function of E-selectin in LAS. These findings not only offer valuable insights into the mechanisms underlying IS and its subtypes but also help inform personalized stroke prevention strategies.
目的:内皮功能障碍与缺血性卒中(is)的发病机制有关,但其因果关系尚不清楚。本研究通过综合观察和遗传证据系统地探讨了内皮功能障碍蛋白与IS及其亚型之间的因果关系。方法:采用系统荟萃分析和孟德尔随机化(MR)相结合的两阶段研究。荟萃分析整合了29项观察性研究的数据,以评估内皮功能障碍蛋白(vWF、sE-selectin、sP-selectin、ICAM-1、VCAM-1、sLOX-1、VEGF、ET-1、SDF-1)与IS之间的关系。该荟萃分析已在线注册(PROSPERO ID: CRD42023461783)。随后的MR应用于识别内皮功能障碍蛋白对IS及其亚型的因果影响,利用遗传工具变异。结果:一项荟萃分析显示vWF、se -选择素、ICAM-1、sp -选择素、sLOX-1和VEGF与IS有显著相关性(均为p)。结论:这项工作提供了内皮功能障碍显著促进IS的因果证据,突出了vWF在CES中的血栓形成活性和e -选择素在LAS中的炎症功能。这些发现不仅对IS及其亚型的潜在机制提供了有价值的见解,而且有助于为个性化的卒中预防策略提供信息。

Premature rupture of membranes is one of the more common symptoms of pregnant women before labor, which can lead to an increased rate of preterm birth and a higher mortality rate of the fetus born from it. The current research on premature rupture of membranes (PROM) is mainly based on multivariate regression analysis, and variables are selected for multivariate regression analysis after univariate analysis. This method may omit some independent variables, resulting in one-sided analysis results. In this context, this study uses Bayesian method and Logistic regression analysis to construct a new variable analysis model to analyze the clinical characteristics and risk factors of PROM infection. First, through Bayesian Logistic regression, the clinical features of PROM infection mainly include fever, increased white blood cells and C-reactive protein, and increased fetal heart rate. The analysis of risk factors showed that pathogen infection, maternal pregnancy number, and scarred uterus were all risk factors for PROM infection. Finally, in order to explain the effect of the analysis model used in this paper, a nonparametric test, AUC value and ROC curve were used to compare the effect of Bayesian Logistic regression and Logistic regression. The results showed that the statistic value of Bayesian logistic regression was 0.177 higher than that of logistic regression, and the AUC value was 0.014 higher. That is, the performance of the Bayesian logistic regression model is better. The method used in the experiment is feasible, and the experimental results are in line with expectations.
胎膜早破是孕妇临产前较常见的症状之一,可导致早产率增加,由此产生的胎儿死亡率也较高。目前对膜早破(PROM)的研究主要基于多元回归分析,在单因素分析后选择变量进行多元回归分析。这种方法可能会遗漏一些自变量,导致分析结果单侧。在此背景下,本研究采用贝叶斯方法和Logistic回归分析,构建新的变量分析模型,分析胎膜早破感染的临床特征及危险因素。首先,通过贝叶斯Logistic回归分析,胎膜早破感染的临床特征主要有发热、白细胞和c反应蛋白升高、胎心率升高。危险因素分析表明,病原菌感染、产妇妊娠数、瘢痕子宫均为胎膜早破感染的危险因素。最后,为了说明本文所采用的分析模型的效果,采用非参数检验、AUC值和ROC曲线对贝叶斯Logistic回归和Logistic回归的效果进行了比较。结果表明,贝叶斯logistic回归的统计值比logistic回归的统计值高0.177,AUC值高0.014。也就是说,贝叶斯逻辑回归模型的性能更好。实验采用的方法是可行的,实验结果符合预期。

The study aimed to explore the potential mechanism of action of extracellular miRNA-188–3p derived from CAFs in cervical cancer. In this study, CAFs were isolated from patients with cervical cancer, and exosomes were extracted by ultrafast centrifugation method to detect the expression level of miRNA-188–3p in exosomes. Subsequently, the exosomes were co-cultured with cervical cancer cells, and the temperature changes of the cells were monitored by medical thermal image analysis technology to evaluate the metabolic activity of the cells. Western blot and qPCR were used to detect protein and mRNA expression levels related to iron metabolism in order to investigate the role of miRNA-188–3p in iron metabolism of cervical cancer cells. The results showed that the expression level of miRNA-188–3p in exosomes derived from CAFs was significantly higher than that of exosomes derived from normal fibroblasts. Medical thermal image analysis showed that cervical cancer cells treated with miRNA-188–3p showed higher metabolic activity, manifested by increased temperature. The results of cell proliferation test, scratch test and Transwell invasion test all showed that miRNA-188–3p promoted the proliferation, migration and invasion of cervical cancer cells. Further molecular mechanism studies showed that miRNA-188–3p regulates iron homeostasis in cervical cancer cells by targeting genes related to iron metabolism, thereby promoting cell proliferation and invasion.
本研究旨在探讨源自cas的细胞外miRNA-188-3p在宫颈癌中的潜在作用机制。本研究从宫颈癌患者中分离出CAFs,采用超快离心法提取外泌体,检测miRNA-188-3p在外泌体中的表达水平。随后,将外泌体与宫颈癌细胞共培养,利用医学热图像分析技术监测细胞的温度变化,评价细胞的代谢活性。采用Western blot和qPCR检测铁代谢相关蛋白和mRNA的表达水平,探讨miRNA-188-3p在宫颈癌细胞铁代谢中的作用。结果表明,CAFs来源的外泌体中miRNA-188-3p的表达水平显著高于正常成纤维细胞来源的外泌体。医学热像分析显示,经miRNA-188-3p处理的宫颈癌细胞代谢活性较高,表现为温度升高。细胞增殖试验、划痕试验和Transwell侵袭试验结果均显示miRNA-188-3p促进宫颈癌细胞增殖、迁移和侵袭。进一步的分子机制研究表明,miRNA-188-3p通过靶向铁代谢相关基因调控宫颈癌细胞铁稳态,从而促进细胞增殖和侵袭。

Background and Purpose

High-resolution magnetic resonance imaging (HR-MRI) is increasingly used to assess intracranial atherosclerosis (ICAS). The risks for anterior circulation stroke (ACS) and posterior circulation stroke (PCS) differ, and understanding the factors influencing these differences is important for better clinical management. This study investigates the impact of clinical risk factors on ICAS features in ACS and PCS using HR-MRI, focusing on arterial remodeling patterns.

Methods

This retrospective, cross-sectional study uses HR-MRI to investigate the differences in plaque characteristics and remodeling patterns between anterior and posterior circulation strokes (ACS and PCS). Consecutive patients with acute ischemic stroke or transient ischemic attack (TIA) who received HR-MRI from January 2021 to August 2022 were enrolled. We compared ACS and PCS cases, analyzed clinical and radiological features, and examined factors associated with arterial remodeling patterns.

Results

Of 208 patients, 123 had ACS, and 85 had PCS. PCS was significantly associated with diabetes (P = 0.036) and positive remodeling (P = 0.01). Differences in HbA1c, fibrinogen levels, and plaque enhancement were observed between ACS and PCS (P < 0.001; P = 0.033; P = 0.03). Multivariable analysis identified smoking (P = 0.048; OR: 1.96, 95 % CI: 1.01–3.81) and uric acid levels (P = 0.022; OR: 0.996, 95 % CI: 0.993–0.999) as independent factors associated with non-positive remodeling.

Conclusions

HR-MRI reveals significant differences in risk factors and plaque characteristics between ACS and PCS, with smoking and uric acid levels associated with non-positive remodeling. These findings highlight the importance of HR-MRI in identifying plaque vulnerability and guiding clinical interventions.
背景与目的:高分辨率磁共振成像(HR-MRI)越来越多地用于颅内动脉粥样硬化(ICAS)的评估。前循环卒中(ACS)和后循环卒中(PCS)的风险不同,了解影响这些差异的因素对更好的临床管理很重要。本研究利用HR-MRI研究临床危险因素对ACS和PCS的ICAS特征的影响,重点关注动脉重塑模式。方法:本回顾性横断面研究采用高分辨率磁共振成像技术研究前后循环卒中(ACS和PCS)斑块特征和重塑模式的差异。在2021年1月至2022年8月期间连续接受HR-MRI检查的急性缺血性卒中或短暂性脑缺血发作(TIA)患者入组。我们比较了ACS和PCS病例,分析了临床和影像学特征,并检查了与动脉重塑模式相关的因素。结果:208例患者中,ACS 123例,PCS 85例。PCS与糖尿病(P = 0.036)和正重构(P = 0.01)显著相关。ACS和PCS患者在HbA1c、纤维蛋白原水平和斑块增强方面存在差异(P < 0.001;P = 0.033; = 0.03页)。多变量分析发现吸烟(P = 0.048;OR: 1.96, 95% CI: 1.01-3.81)和尿酸水平(P = 0.022;OR: 0.996, 95% CI: 0.993-0.999)是与非阳性重塑相关的独立因素。结论:HR-MRI显示ACS和PCS的危险因素和斑块特征有显著差异,吸烟和尿酸水平与非阳性重构相关。这些发现强调了HR-MRI在识别斑块易感性和指导临床干预方面的重要性。

Irregular diet, lack of exercise, and poor sleep quality have led to various diseases, with chronic conditions like hyperlipidemia being most common among the elderly. With advances in the medical Internet of Things (MIoT), medical data now supports more effective care strategies. Health management intervention, as a novel approach, aims to improve elderly patients’ understanding and management of chronic diseases. In this study, 200 elderly patients with hyperlipidemia were randomly divided into a control group (routine care) and an experimental group (health management intervention). Results showed that health knowledge mastery improved significantly with intervention—rising from 61.8 % to 74.4 % in males and from 56.8 % to 71.6 % in females. Thus, health management intervention based on medical data effectively enhances patients’ health literacy.

Sample preparation (i.e., isolation and purification of pathogens from samples) remains one of the bottlenecks limiting deployment of diagnostic tests. Two recent examples highlighting these limitations include the difficulties in widespread nucleic acid testing during COVID-19 and in identifying drug-resistant infections. Unmet needs include systems that work with different bodily fluids and samples, multiple types of suspected pathogen, and function in a rapid and semi-automated fashion. Advances such as these could accelerate the deployment of novel diagnostic tests by eliminating upstream sample preparation bottlenecks.
Herein, we tested the feasibility of combining multiple pathogen-binding paramagnetic beads with magnetic ratcheting-based enrichment to directly isolate microbes from samples. We demonstrate effective use of three different paramagnetic bead-conjugated proteins (mannose binding lection [MBL], C-reactive protein [CRP], and dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin [DC-SIGN]) to capture 18 different bacteria species and model virus particles/peptides. We used magnetic ratcheting to isolate bead-bound microbes from milliliters (mLs) of sample at concentrations of 4 – 4000 microbes per mL. The flow-through system was operated up to 1 mL per minute and enabled pathogen isolation from 10 mL samples in <30 min. Demonstration of post-ratcheting PCR-based microbe analysis was also performed, showing that the technology may have applicability across different infectious agents, sample types/volumes, and analytical assays. Based on these results, further studies are warranted to test clinical samples, compare results to current gold-standard diagnostic methods, and test the sample preparation technologies across additional pathogen types.
样品制备(即从样品中分离和纯化病原体)仍然是限制诊断测试部署的瓶颈之一。最近的两个例子突出了这些局限性,包括在COVID-19期间广泛进行核酸检测和识别耐药感染方面的困难。未满足的需求包括处理不同体液和样本、多种疑似病原体的系统,以及以快速和半自动化方式运作的系统。诸如此类的进展可以通过消除上游样品制备瓶颈来加速新型诊断测试的部署。在此,我们测试了将多个病原体结合的顺磁珠与基于磁棘轮的富集相结合以直接从样品中分离微生物的可行性。我们证明了三种不同的顺磁珠偶联蛋白(甘露糖结合选择蛋白[MBL], c反应蛋白[CRP]和树突状细胞特异性细胞间粘附分子-3抓取非整合素[DC-SIGN])有效地捕获了18种不同的细菌物种和模型病毒颗粒/肽。我们使用磁棘轮从毫升(mL)样品中分离出头结合微生物,浓度为每mL 4 - 4000个微生物。流式系统以每分钟1 mL的速度运行,并在不到30分钟的时间内从10 mL样品中分离出病原体。我们还进行了棘轮后pcr微生物分析的演示,表明该技术可能适用于不同的感染因子、样品类型/体积和分析分析。基于这些结果,有必要进行进一步的研究,以测试临床样品,将结果与当前的金标准诊断方法进行比较,并测试其他病原体类型的样品制备技术。

Migraine is a kind of common clinical headache. Because its etiology is unknown and the curative effect is not very ideal, recent studies have shown that the activation of trigeminal ganglion has a certain impact on the occurrence of migraine. In this paper, the rat migraine model was established by subcutaneous injection of nitroglycerin. Reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemical techniques were used to observe the changes and correlation of the phosphatase and tensin homolog deleted on chromosome ten (PTEN), protein kinase B (Akt) and cAMP response element binding protein (CREB) expressions in trigeminal ganglia of migraine rats at gene and protein levels, respectively, in order to explore the relationship and role of these three genes in the pathogenesis of migraine. It can be seen from the experimental results that after the treatment of nickel carbohydrazide perchlorate (GTN), the expression level of PTEN mRNA in trigeminal ganglion decreased significantly, and it was the lowest at 12 h of GTN, with a value of 0.21. However, over time, PTEN mRNA expression level has rose to 0.44 after GTN24h, reaching the initial level. According to the calculation, PTEN was significantly negatively correlated with Akt protein expression, and its P value was <0.05. The experiment in this paper first proved that the attack rate of migraine in women was higher than that in men, and then proved the relationship between PTEN, Akt and CREB genes in the trigeminal ganglion of migraine.
偏头痛是临床上常见的一种头痛。由于其病因不明,疗效也不是很理想,最近的研究表明,三叉神经节的激活对偏头痛的发生有一定的影响。本文采用硝酸甘油皮下注射法建立大鼠偏头痛模型。采用反转录聚合酶链反应(RT-PCR)和免疫组织化学技术分别在基因和蛋白水平上观察偏头痛大鼠三叉神经节中10号染色体上缺失的磷酸酶和紧张素同源物(PTEN)、蛋白激酶B (Akt)和cAMP反应元件结合蛋白(CREB)表达的变化及相关性,探讨这三个基因在偏头痛发病中的关系和作用。从实验结果可以看出,经高氯酸碳酰脲镍(GTN)处理后,三叉神经节中PTEN mRNA的表达水平显著降低,在GTN处理12h时表达水平最低,为0.21。但随着时间的推移,PTEN mRNA的表达水平在GTN24h后上升至0.44,达到初始水平。经计算,PTEN与Akt蛋白表达呈显著负相关,P值均小于0.05。本文的实验首先证明了女性偏头痛的发病率高于男性,然后证明了偏头痛三叉神经节中PTEN、Akt和CREB基因之间的关系。

Covalent drug discovery has garnered renewed interest due to its potential to target proteins previously considered "undruggable." Intact protein mass spectrometry (MS) is a critical technique for providing direct evidence of covalent drug modifications to protein targets. However, its application for screening covalent libraries has been hindered by low assay throughput, complex sample preparation, and high protein consumption associated with traditional liquid chromatography-MS (LC-MS) or solid-phase extraction-MS (SPE-MS) platforms. The recent integration of acoustic ejection (AE) with electrospray ionization (ESI) source of high-resolution time-of-flight (TOF) mass spectrometers—specifically, the SCIEX Echo® MS+ with the ZenoTOF 7600—has enabled the direct introduction of intact proteins without desalting at nanoliter volumes from 384 or 1536 well plates into the electrospray ionization (ESI) source of the mass spectrometer, achieving analysis rates of 1–2 seconds per sample. This advancement offers significant potential for covalent library screening and kinetic studies of identified hits due to ultrafast sample introduction and minimal sample consumption. To fully automate this pipeline, the SCIEX Echo® MS+ with ZenoTOF 7600 mass spectrometer was integrated with our internal automation system (HighRes Biosolutions) and the data analysis workflow was automated. Using Bruton’s tyrosine kinase (BTK) as a model, we demonstrated that this integrated pipeline could accelerate covalent drug discovery through covalent library screens, off-target reactivity assessment via GSH reactivity assays, and potency evaluation through kinact/Ki measurements.
共价药物的发现已经获得了新的兴趣,由于其潜在的目标蛋白质以前被认为是“不可药物”。完整蛋白质谱(MS)是提供共价药物修饰蛋白靶点的直接证据的关键技术。然而,由于传统的液相色谱-质谱(LC-MS)或固相萃取-质谱(SPE-MS)平台检测通量低、样品制备复杂、蛋白质消耗高,阻碍了其在共价文库筛选中的应用。最近集成了声波喷射(AE)与高分辨率飞行时间(TOF)质谱仪的电喷雾电离(ESI)源,特别是SCIEX Echo®MS+与ZenoTOF 7600,可以直接将完整的蛋白质从384或1536孔板中引入到质谱仪的电喷雾电离(ESI)源中,而无需以纳升的体积进行脱盐,每个样品的分析速率为1-2秒。由于超快的样品导入和最小的样品消耗,这一进展为共价文库筛选和鉴定命中的动力学研究提供了巨大的潜力。为了完全自动化这条流水线,SCIEX Echo®MS+与ZenoTOF 7600质谱仪与我们的内部自动化系统(HighRes Biosolutions)集成,数据分析工作流程实现自动化。以布鲁顿酪氨酸激酶(Bruton’s tyrosine kinase, BTK)为模型,我们证明了这个整合的管道可以通过共价文库筛选、GSH反应性分析的脱靶性评估以及kinact/Ki测量的效价评估来加速共价药物的发现。

Using Bruton’s tyrosine kinase (BTK) as a model, we demonstrated that this integrated pipeline could accelerate covalent drug discovery through covalent library screens, off-target reactivity assessment via GSH reactivity assays, and potency evaluation through k<sub>inact</sub>/K<sub>i</sub> measurements.</div></div>","PeriodicalId":54248,"journal":{"name":"SLAS Technology","volume":"33 ","pages":"Article 100307"},"PeriodicalIF":2.5,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144254755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
