Background

Epstein–Barr Virus (EBV) is a widespread human γ-herpesvirus linked to cancers and autoimmune diseases, but limited comprehensive bibliometric analysis appear to have been conducted in this field.

Methods

Using Web of Science data, 16,318 EBV-related documents (2014–2023) were analyzed via VOSviewer, Bibliometrix, and Citespace following the Strengthening the Reporting of Observational Studies in Epidemiology reporting guideline.

Results

This cross-sectional bibliometric analysis of 16,318 EBV-related documents (2014–2023) revealed a consistent upward trend in annual publications, reflecting growing global interest in EBV research. Collaborative networks demonstrated strong international partnerships, particularly between the United States and China. Keywords co-occurrence and burst analysis highlighted enduring focus on EBV pathogenesis, immune evasion mechanisms, and EBV-associated diseases like nasopharyngeal carcinoma, Hodgkin lymphoma, and multiple sclerosis. On the basis of this comprehensive bibliometric analysis, it showed that the emerging hotspots included immunotherapy, biomarkers, viral reactivation, and vaccine development, with clinical trials evaluating immune-checkpoint inhibitors of toripalimab, mRNA-based therapeutic vaccines targeting LMP2 and EBNA1, and prophylactic strategies such as glycoproteins-based ferritin nanoparticles or mRNA vaccines, indicating a shift toward precision interventions.

Conclusions

EBV research has grown exponentially, driven by insights into structural-function relationships and immune evasion. Advances enable targeted prophylactic/therapeutic strategies. The analysis highlights needs to decode virus-host interactions, optimize vaccines, and translate findings clinically, aiming to raise disease awareness, guide immunotherapies, and reduce global health burdens.
eb病毒(depstein - barr Virus, EBV)是一种广泛存在的人类γ-疱疹病毒,与癌症和自身免疫性疾病有关,但在这一领域进行的综合文献计量分析有限。方法采用Web of Science数据库,采用VOSviewer、Bibliometrix和Citespace软件对2014-2023年的16318篇ebv相关文献进行分析。结果对2014-2023年的16,318篇EBV相关文献进行的横断面文献计量分析显示,年度出版物呈持续上升趋势,反映了全球对EBV研究的兴趣日益浓厚。协作网络展示了强有力的国际伙伴关系,特别是美国和中国之间的伙伴关系。关键词共现和突发分析强调了EBV发病机制、免疫逃避机制以及EBV相关疾病如鼻咽癌、霍奇金淋巴瘤和多发性硬化症的长期关注。综合文献计量学分析显示,新兴的热点包括免疫治疗、生物标志物、病毒再激活和疫苗开发,临床试验评估了免疫检查点抑制剂托利帕单抗、靶向LMP2和EBNA1的基于mRNA的治疗性疫苗,以及基于糖蛋白的铁蛋白纳米颗粒或mRNA疫苗等预防策略,表明了向精确干预的转变。结论在对结构-功能关系和免疫逃避的深入研究推动下,对sebv的研究呈指数增长。进步使有针对性的预防/治疗策略成为可能。该分析强调需要解码病毒与宿主的相互作用,优化疫苗,并将研究结果转化为临床,旨在提高疾病意识,指导免疫疗法,并减轻全球卫生负担。

Background

Patients with COVID-19 exhibited a variety of clinical characteristics. However, there is currently insufficient evidence to delineate the differences in clinical symptomatology between primary infection and reinfection. This study aims to compare the clinical symptom characteristics between primary infection and reinfection during COVID-19.

Methods

This research utilized a convenience sampling method to gather survey data from Chinese individuals aged 18 to 60 years across China. Questionnaire assessments were conducted to collect data on general demographic and clinical information during the COVID-19 pandemic in China. The collected data were analyzed using IBM SPSS 26.0 software.

Results

This study analyzed 1156 patients. During second infection, the frequency of fever, painful muscles, ageusia or anosmia, headache, back pain, feeling hot and cold alternately, general tiredness, tingling extremities, heavy arms or legs, and chest pain symptoms were significantly lower. However, the rate of sneezing, runny nose, and stuffy nose were significantly higher (p < 0.05). The proportion of patients with symptoms lasting 3–4 weeks and a body temperature of 38.1–41.0°C was significantly lower during second infection (p < 0.05). The cases infected with COVID-19 for the second time had a higher proportion of nurses and a higher proportion of individuals who received one or two doses of the COVID-19 vaccine (p < 0.05).

Conclusions

The analysis of COVID-19 cases showed significant differences in demographic and clinical symptom characteristics between the first-time and second-time positive populations. This understanding can help guide changes in management strategies.
COVID-19患者表现出多种临床特征。然而,目前没有足够的证据来描述原发性感染和再感染之间的临床症状差异。本研究旨在比较新冠肺炎患者初次感染与再感染的临床症状特征。方法本研究采用方便抽样的方法,在中国各地收集18 - 60岁的中国人的调查数据。通过问卷调查收集中国新冠肺炎大流行期间的一般人口学和临床信息。采用IBM SPSS 26.0软件对收集的数据进行分析。结果本研究分析了1156例患者。第二次感染时,发热、肌肉疼痛、耳聋或嗅觉丧失、头痛、背痛、冷热交替、全身乏力、四肢刺痛、胳膊或腿重、胸痛症状出现频率明显降低。然而,打喷嚏、流鼻涕和鼻塞的发生率显著高于对照组(p <;0.05)。第二次感染时症状持续3 ~ 4周、体温38.1 ~ 41.0℃的患者比例明显降低(p <;0.05)。第二次感染COVID-19的病例中,护士比例更高,接种1剂或2剂COVID-19疫苗的个体比例更高(p <;0.05)。结论COVID-19病例分析显示,首次和二次阳性人群的人口学特征和临床症状特征存在显著差异。这种理解可以帮助指导管理策略的变化。

巨细胞病毒(CMV)是肺移植术后常见的机会性病原体,与移植后并发症和不良结局相关。本研究旨在评估通过新一代宏基因组测序(mNGS)鉴定的CMV dna血症在肺移植术后早期的发生率,并评估其对接受者短期预后的影响。方法回顾性分析2020年5月至2023年11月南京医科大学附属无锡市人民医院115例肺移植患者的临床资料。根据mngs检测的CMV dna血症情况,将患者分为dna血症组和正常组。非参数检验(Mann-Whitney U/Wilcoxon sign -rank)和混合效应模型用于组间比较。Kaplan-Meier生存分析,对总生存差异进行log-rank检验。单变量logistic回归确定ICU死亡率和90天死亡率的危险因素。多因素logistic回归校正混杂因素。采用倾向评分匹配(1∶1最优近邻,caliper = 0.25)解决协变量失衡问题,对匹配队列进行单因素logistic回归分析。结果在肺移植术后早期,mNGS检测到CMV dna血症,发生率为15.7%。与正常组相比,CMV dna血症组的90天总生存率显著降低,Log-rank检验显示两组之间的生存差异具有统计学意义(p <;0.001)。单因素和多因素logistic回归分析发现,CMV dna血症是ICU全因死亡率的独立危险因素(OR = 5.00, 95% CI: 1.37-18.27, p = 0.015),而其他病原体感染独立预测90天全因死亡率(OR = 3.40, 95% CI: 1.10-10.44, p = 0.033)。在倾向评分匹配后,CMV dna血症组和正常组的基线特征很好地平衡。在匹配的队列中,单因素logistic回归进一步证实CMV dna血症是ICU死亡率的独立危险因素(OR = 7.43, 95% CI: 1.23-45.00, p = 0.029)。中介分析表明,共病原体感染介导了巨细胞病毒dna血症与90天全因死亡率之间的关系,中介比例为20.6% (95% CI: 1.7%-138.5%, p <;0.001)。结论ngs显示肺移植术后早期CMV dna血症的发生率高于既往报道。巨细胞病毒dna血症与不良预后显著相关。尽管样本量和回顾性设计存在局限性,但本研究为移植后巨细胞病毒的监测和管理提供了新的见解。未来的研究应确定以mNGS为指导的先发制人抗病毒策略的最佳时机。

Background

Extrapulmonary tuberculosis (EPTB) complicates pulmonary tuberculosis (PTB) management. Diabetes mellitus impairs immune function, worsening tuberculosis (TB) outcomes.

Methods

This retrospective study investigates the effect of glycemic control on immune function and TB dissemination in 1,768 TB patients (2022–2024). Patients were stratified by glycated hemoglobin (HbA1c) levels (≤ 6% vs. > 6%) and fasting blood glucose (FBG) concentrations (< 7 vs. ≥ 7 mmol/L). Lymphocyte subsets (CD3+, CD4+, CD8+ T cells, CD19+ B cells, and CD16+CD56+ natural killer cells) were compared between glycemic control and TB groups. Multiple regression and threshold effect analysis were conducted to assess the effects of HbA1c and CD3+ T cells on TB dissemination and their critical values.

Results

Poor glycemic control was associated with lower cell counts of all lymphocyte subsets in patients with PTB (all p < 0.0001). Similar reductions were observed in patients with concurrent PTB and EPTB (PTB + EPTB) when HbA1c values > 6% (all p < 0.05). When HbA1c values ≤ 6% or FBG concentrations < 7 mmol/L, patients with PTB + EPTB showed lower immune cell counts than PTB (p < 0.05). Multiple regression indicated HbA1c increased TB dissemination risk (OR = 10.95), while CD3+ T cells showed protective effects. Threshold effect analysis identified an HbA1c values ≥ 7.4% for metabolic control and CD3+ T cell thresholds of 387/µL (immune deficiency) and 2,100/µL (immune overactivation).

Conclusions

Poor glycemic control impairs immune cells, while EPTB further reduces immune cell numbers. Integrated glycemic management and immunological monitoring help optimize treatment strategies and improve clinical outcomes, particularly in patients at risk for EPTB.
背景:肺痨(EPTB)是肺结核(PTB)治疗的并发症。糖尿病损害免疫功能,恶化结核病(TB)结局。方法回顾性研究2022-2024年1768例结核病患者血糖控制对免疫功能和结核传播的影响。根据糖化血红蛋白(HbA1c)水平对患者进行分层(≤6% vs. >;6%)和空腹血糖(FBG)浓度(<;7 vs.≥7 mmol/L)。比较血糖控制组和TB组的淋巴细胞亚群(CD3+、CD4+、CD8+ T细胞、CD19+ B细胞和CD16+CD56+自然杀伤细胞)。采用多元回归和阈值效应分析评估HbA1c和CD3+ T细胞对TB传播的影响及其临界值。结果PTB患者血糖控制不佳与所有淋巴细胞亚群细胞计数降低相关(p <;0.0001)。当HbA1c值为>时,合并PTB和EPTB (PTB + EPTB)的患者也观察到类似的降低;6%(全部p <;0.05)。当HbA1c值≤6%或FBG浓度<;7 mmol/L, PTB + 患者的免疫细胞计数低于PTB (p <;0.05)。多元回归表明,HbA1c增加了TB传播风险(OR = 10.95),而CD3+ T细胞具有保护作用。阈值效应分析确定HbA1c值≥7.4%用于代谢控制,CD3+ T细胞阈值为387/µL(免疫缺陷)和2100 /µL(免疫过度激活)。结论血糖控制不良可损害免疫细胞,EPTB可进一步降低免疫细胞数量。综合血糖管理和免疫监测有助于优化治疗策略和改善临床结果,特别是对有EPTB风险的患者。

Zoonotic diseases, which constitute 60% of all human infectious diseases, present substantial risks to public health, economies, and livelihoods. These diseases emerge at the human-animal-environment interface, with occupational exposure representing a critical yet underexamined dimension of zoonotic risk. Workers in high-risk sectors such as agriculture, wildlife management, and laboratory research face elevated exposure to zoonotic pathogens, often under conditions of inadequate preventive measures and resource constraints. Neurological disorders resulting from zoonotic infections, including Guillain-Barré syndrome, encephalitis, and meningitis, illustrate the severe health consequences for occupational groups. Cases linked to swine hepatitis E virus, West Nile virus, Streptococcus suis, and Baylisascaris procyonis underscore the urgent need for robust surveillance and targeted interventions.
The Ecohealth approach, integrated with the One Health framework, provides a transformative model for managing zoonotic risks by addressing the upstream drivers of disease emergence. By emphasizing environmental stewardship, ecological balance, and socio-economic equity, Ecohealth fosters sustainable preventive strategies. Occupational medicine is crucial in linking workplace safety with public health through tailored risk management, enhanced surveillance, and targeted education.
Despite these frameworks, significant barriers persist, including data gaps, underreporting of occupational diseases, and insufficient coordination among health sectors. Addressing these challenges requires implementing standardized occupational health surveillance systems, enhancing reporting mechanisms through digital tools, and promoting cross-sectoral data-sharing initiatives. Successful models, such as sentinel surveillance programs in agricultural sectors and integrated biosurveillance networks, demonstrate the feasibility of these strategies. Leveraging these approaches can facilitate early detection, improve reporting accuracy, and support evidence-based interventions.
人畜共患疾病占所有人类传染病的60%,对公共卫生、经济和生计构成重大风险。这些疾病出现在人-动物-环境界面,职业暴露是人畜共患风险的一个关键但尚未得到充分研究的方面。农业、野生动物管理和实验室研究等高风险部门的工作人员往往在预防措施不足和资源限制的情况下,面临着人畜共患病原体暴露的增加。人畜共患感染引起的神经系统疾病,包括格林-巴罗综合征、脑炎和脑膜炎,说明了职业群体的严重健康后果。与猪戊型肝炎病毒、西尼罗病毒、猪链球菌和原虫贝利蛔虫有关的病例强调迫切需要进行强有力的监测和有针对性的干预。生态卫生方法与“同一个健康”框架相结合,通过解决疾病出现的上游驱动因素,为管理人畜共患病风险提供了一种变革性模式。通过强调环境管理、生态平衡和社会经济公平,生态健康促进可持续的预防战略。通过有针对性的风险管理、加强监测和有针对性的教育,职业医学在将工作场所安全与公共卫生联系起来方面至关重要。尽管有这些框架,但仍然存在重大障碍,包括数据差距、职业病漏报以及卫生部门之间协调不足。应对这些挑战需要实施标准化的职业健康监测系统,通过数字工具加强报告机制,并促进跨部门数据共享举措。成功的模式,如农业部门的哨点监测计划和综合生物监测网络,证明了这些战略的可行性。利用这些方法可以促进早期发现,提高报告准确性,并支持基于证据的干预措施。

Backgroud

Coltiviruses are spherical, non-enveloped viruses with 12 double-stranded RNA segments, belonging to the family Spinareoviridae, and predominantly transmitted by ticks. This study isolated and characterized a novel coltivirus, designated Woodland tick reovirus (WLTRV), from Haemaphysalis concinna ticks collected in Helong City, Jilin Province, in Northeastern China.

Methods

SW-13 and Vero cells were used to isolate WLTRV through three blind passages, while seven mammalian cell lines assessed viral growth. Viral morphology was observed by electron microscopy. Next-generation sequencing, 5ʹ and 3ʹ rapid amplification of cDNA ends were used to determine WLTRV whole genome sequences, and phylogenetic methods were used to characterize WLTRV. A real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect WLTRV RNA in ticks.

Results

WLTRV grew and exerted cytopathic effects in human (SW-13 and 293T) and mouse (BHK-21 and N2A) cell lines, revealing its potential to infect mammals. Phylogenetic analysis based on RNA-dependent RNA polymerase sequences classified WLTRV within the genus Coltivirus, with a close evolutionary relationship to Tarumizu tick virus. The nucleotide and amino acid sequence homologies between WLTRV and Tarumizu tick virus across the 12 segments analyzed ranged from approximately 44.79% to 69.09% and 33.73% to 75.60%, respectively. WLTRV shared conserved the 5ʹ-terminal (GACAA/UU/A) and 3ʹ-terminal (UGCAGUC) consensus sequences of the genus Coltivirus genomes. Electron microscopy revealed WLTRV as spherical (diameter ∼80 nm), non-enveloped, and morphologically consistent with coltiviruses. Among the 4,717 ticks collected from six towns in the Yanbian Korean Autonomous Prefecture, WLTRV RNA was only detected in H. concinna (0.95% virus-carrying rate) but not in Haemaphysalis japonica, Haemaphysalis longicornis, Ixodes persulcatus, and Dermacentor silvarum.

Conclusions

This study represents the first isolation and identification of WLTRV from H. concinna in the Yanbian Korean Autonomous Prefecture, providing new insights into the genetic diversity and evolution of the genus Coltivirus.
结肠炎病毒是球形的无包膜病毒,有12个双链RNA片段,属于棘状病毒科,主要通过蜱传播。本研究从吉林省和龙市采集的血蜱中分离并鉴定了一种新型结肠炎病毒——林地蜱呼肠孤病毒(WLTRV)。方法利用ssw -13和Vero细胞进行3次盲传分离WLTRV,同时用7个哺乳动物细胞系评估病毒生长情况。电镜观察病毒形态。采用新一代测序、cDNA末端5′和3′快速扩增方法确定WLTRV全基因组序列,并采用系统发育方法对WLTRV进行表征。采用实时定量聚合酶链反应(RT-qPCR)检测蜱WLTRV RNA。结果swltrv在人(SW-13和293T)和小鼠(bkh -21和N2A)细胞系中生长并发挥细胞病变作用,揭示了其感染哺乳动物的潜力。基于RNA依赖RNA聚合酶序列的系统发育分析将WLTRV归为结肠炎病毒属,与Tarumizu蜱病毒有密切的进化关系。WLTRV与Tarumizu蜱病毒12个片段的核苷酸和氨基酸序列同源性分别在44.79% ~ 69.09%和33.73% ~ 75.60%之间。WLTRV具有Coltivirus属基因组的5′-末端(GACAA/UU/A)和3′-末端(UGCAGUC)一致序列。电镜显示WLTRV为球形(直径~ 80 nm),无包膜,形态与结肠炎病毒一致。在延边朝鲜族自治州6个镇采集的4717只蜱中,WLTRV RNA仅在携带病毒率为0.95%的白腹血蜱中检出,而在日本血蜱、长角血蜱、过角硬蜱和森林革蜱中未检出。结论本研究首次在延边朝鲜族自治州分离并鉴定出结肠炎病毒,为结肠炎病毒属的遗传多样性和进化提供了新的认识。

Background

Human adenovirus type 3 (HAdV-3) and 7 (HAdV-7) are significant causative agents of acute respiratory tract infections that are prevalent among school-based outbreaks across China. Rapid and accurate diagnosis is crucial for effective control and treatment of HAdV infection.

Methods

Here, we developed a novel diagnostic assay combining multiple cross displacement amplification (MCDA) with CRISPR-Cas12b technology, designated HAdV-MCDA-CRISPR, to rapidly detect HAdV-3 and HAdV-7. The assay targets a highly conserved region of the hexon gene, enabling broad detection of these serotypes. The protocol includes DNA extraction (15 minutes), MCDA amplification (40 minutes), and CRISPR detection (5 minutes), and is completed within one hour. Specificity was validated by testing against non-HAdV pathogens, while sensitivity was assessed using serial dilutions of hexon-containing plasmid DNA. Clinical performance was evaluated using 88 patient samples.

Results

The HAdV-MCDA-CRISPR assay demonstrated high sensitivity, detecting as little as 5 fg HAdV plasmid DNA per reaction, and showed no cross-reactivity with other common respiratory pathogens. Clinical validation using 88 patient samples further demonstrated the diagnostic accuracy of HAdV-MCDA-CRISPR.

Conclusions

HAdV-MCDA-CRISPR is a rapid, sensitive, and specific tool for diagnosing HAdV-3 and HAdV-7 infections, offering potential for timely clinical intervention and enhanced epidemiological surveillance.
人类腺病毒3型(HAdV-3)和7型(HAdV-7)是急性呼吸道感染的重要病原体,在中国以学校为基础的疫情中普遍存在。快速准确的诊断对于有效控制和治疗hav感染至关重要。方法本研究建立了一种结合多重交叉位移扩增(multiple cross - displacement amplification, MCDA)和CRISPR-Cas12b技术的新型诊断方法,命名为HAdV-MCDA-CRISPR,用于快速检测HAdV-3和HAdV-7。该检测针对六邻体基因的高度保守区域,能够广泛检测这些血清型。程序包括DNA提取(15分钟)、MCDA扩增(40分钟)、CRISPR检测(5分钟),1小时内完成。特异性是通过检测非hav病原体来验证的,而敏感性是通过连续稀释含六己体的质粒DNA来评估的。使用88例患者样本评估临床表现。结果hav - mcda - crispr检测方法灵敏度高,每次反应可检出5fg hav质粒DNA,且与其他常见呼吸道病原体无交叉反应。88例患者样本的临床验证进一步证明了HAdV-MCDA-CRISPR的诊断准确性。结论shadv - mcda - crispr是一种快速、灵敏、特异的诊断HAdV-3和HAdV-7感染的工具,为临床及时干预和加强流行病学监测提供了可能。

Pyogenic liver abscess (PLA) is a potentially life-threatening disease. Early diagnosis and appropriate treatment are crucial to ensure high-quality healthcare for patients with PLA. However, this is complicated by their non-specific clinical symptoms. In addition, the etiologic organisms responsible for PLA are frequently culture-negative, thus complicating clinical decision-making. Here, we report a case of PLA caused by Streptococcus intermedius, as identified via DNA metagenomic sequencing of plasma.
