Helicobacter pylori, a gram-negative microaerophilic bacterium, is implicated in a broad spectrum of upper gastrointestinal disorders, including chronic gastritis, peptic ulcers, gastric cancer, and even certain extragastric diseases. Its ability to colonize and persist within the host is driven by a complex arsenal of colonization and virulence factors, underscoring the intricate dynamics of host–pathogen interactions. The clinical management of H. pylori remains challenging, primarily due to the absence of commercially available vaccines and the increasing prevalence of multidrug resistance. Accurate and reliable detection methods are therefore critical for preventing infections, identifying antibiotic resistance, and assessing treatment efficacy. Currently, both invasive and non-invasive diagnostic approaches are employed, each with unique strengths and limitations. This review provides a comprehensive overview of H. pylori pathogenesis, diagnostic strategies, and therapeutic interventions, highlighting the latest advancements in diagnostic and treatment technologies. By critically evaluating existing methods and exploring innovative approaches, this review aims to support future progress in the effective management of this globally prevalent pathogen.

幽门螺杆菌是一种革兰氏阴性微嗜酸细菌,与多种上消化道疾病有关,包括慢性胃炎、消化性溃疡、胃癌,甚至某些胃外疾病。幽门螺杆菌在宿主体内定植和存活的能力由复杂的定植和毒力因子驱动,凸显了宿主与病原体相互作用的复杂动态。幽门螺杆菌的临床治疗仍然具有挑战性,这主要是由于缺乏商业化疫苗以及多重耐药性的日益普遍。因此,准确可靠的检测方法对于预防感染、识别抗生素耐药性和评估治疗效果至关重要。目前采用的侵入性和非侵入性诊断方法各有其独特的优势和局限性。本综述全面概述了幽门螺杆菌的致病机理、诊断策略和治疗干预措施,重点介绍了诊断和治疗技术的最新进展。通过对现有方法的严格评估和对创新方法的探索,本综述旨在支持未来在有效管理这一全球流行病原体方面取得进展。

Background

Respiratory viruses, such as influenza A and B and respiratory syncytial virus (RSV), pose a severe threat to public health. The precise identification and distinction of these viruses are crucial in clinical laboratories. Here, we comparatively evaluated the performance of the Accunome DXcellence assay and the Cepheid GeneXpert assay in the detection of influenza A and B and RSV in nasopharyngeal swab specimens.

Methods

Four hundred archived nasopharyngeal swab specimens collected for routine clinical analysis were tested in parallel with the Accunome DXcellence assay and Cepheid GeneXpert assay. RNA standards were serially diluted and tested with the Accunome DXcellence assay to calculate the limit of detection (LOD).

Results

The positive and negative percentage agreement between the Accunome DXcellence assay and the Cepheid GeneXpert assay was as follows: 94.9% (74/78) and 100% (321/321), respectively, for influenza A; 98.1% (104/106) and 100% (293/293), respectively, for influenza B; and 100% (22/22) and 100% (377/377), respectively, for RSV. The LODs of the Accunome DXcellence assay for influenza A and B and RSV were 100, 87.5, and 62.5 copies/mL, respectively.

Conclusions

The performance of the Accunome DXcellence assay was similar to that of the Cepheid GeneXpert assay in the detection of influenza A, B, and RSV in nasopharyngeal swab specimens, indicating that the Accunome DXcellence assay is a useful diagnostic tool when these viruses are cocirculating.

呼吸道病毒,如甲型流感和乙型流感以及呼吸道合胞病毒(RSV),对公众健康构成严重威胁。在临床实验室中,准确识别和区分这些病毒是至关重要的。本研究比较了Accunome DXcellence法和Cepheid GeneXpert法检测鼻咽拭子标本中甲型流感、乙型流感和RSV病毒的性能。方法采用Accunome DXcellence法和Cepheid GeneXpert法对临床常规分析的400份存档鼻咽拭子标本进行检测。依次稀释RNA标准品,用Accunome DXcellence法检测,计算检出限(LOD)。结果Accunome DXcellence法与Cepheid GeneXpert法检测甲型流感的正阴性符合率分别为94.9%(74/78)和100% (321/321);乙型流感分别为98.1%(104/106)和100% (293/293);RSV分别为100%(22/22)和100%(377/377)。Accunome DXcellence法检测甲型流感、乙型流感和RSV病毒的lod分别为100、87.5和62.5拷贝/mL。结论Accunome DXcellence检测方法与造父变星GeneXpert检测方法在鼻咽拭子标本中检测甲型流感、乙型流感和RSV的效果相似,表明Accunome DXcellence检测方法在这些病毒共传播时是一种有用的诊断工具。

Diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) are acute, life-threatening complications of diabetes. The overlap of these conditions, termed hyperosmolar diabetic ketoacidosis (H-DKA), is associated with substantial morbidity due to its complex pathophysiology and high complication rates. Notably, cases of H-DKA with glucose levels exceeding 50 mmol/L are rarely reported in the literature. This study details the clinical course of two H-DKA patients who exhibited extreme hyperglycemia at presentation, despite having no prior diagnosis of diabetes. Both patients underwent aggressive fluid resuscitation and insulin therapy, alongside careful management of acute complications. Vital signs and laboratory parameters demonstrated substantial normalization within 3 days of treatment initiation, and no acute or long-term complications related to the therapeutic interventions were observed. These cases underscore the efficacy of timely and intensive therapeutic interventions in mitigating the risks associated with extreme hyperglycemia in H-DKA and highlight critical strategies for optimal patient outcomes.

糖尿病酮症酸中毒(DKA)和高血糖高渗状态(HHS)是急性、危及生命的糖尿病并发症。这些疾病的重叠,被称为高渗性糖尿病酮症酸中毒(H-DKA),由于其复杂的病理生理和高并发症发生率,与大量发病率相关。值得注意的是,文献中很少报道葡萄糖水平超过50 mmol/L的H-DKA病例。本研究详细描述了两名H-DKA患者的临床过程,他们在就诊时表现出极度高血糖,尽管之前没有糖尿病诊断。两名患者均接受了积极的液体复苏和胰岛素治疗,同时对急性并发症进行了精心管理。生命体征和实验室参数在治疗开始3天内基本恢复正常,未观察到与治疗干预相关的急性或长期并发症。这些病例强调了及时和强化治疗干预在减轻H-DKA患者极端高血糖相关风险方面的有效性,并强调了最佳患者预后的关键策略。

Molecular point-of-care testing (POCT) is characterized by high sensitivity, low reagent demand, fast mixing speed, rapid turnaround time, and ease of use, making it appealing for diagnosing infectious diseases. Currently, most commercial molecular POCT systems are based on microfluidic platforms integrating complex fluid manipulation systems, such as sample processing, separation, reaction, and detection, with functional modules on a chip of just a few square centimeters to achieve rapid target detection. This review summarizes the latest advances in molecular POCT systems based on microfluidic platforms for diagnosing infectious diseases from academic and industrial perspectives. First, we cover microfluidic chips, the core component of molecular POCT systems, including materials, preparation processes, fluid drivers, and control units. Then, we describe key techniques implemented in molecular POCT systems for diagnosing infectious diseases, namely nucleic acid detection and reagent storage. Finally, we discuss clinical applications and development directions and highlight challenges in the quality control of molecular POCT systems.

Background

In the rapidly evolving field of molecular diagnostics, identifying a suitable extraction method is crucial in determining the applicability of the point-of-need device. Extraction, which serves as the initial and important step in the diagnostic process, plays a vital role in the accuracy, reliability, and speed of detecting pathogens. Extraction methods range from traditional approaches like organic extraction to modern advancements such as magnetic bead-based separation, each offering unique advantages and limitations.

Methods

This study explored the comparative effectiveness of 10 commercially available protocols (denoted as I–X), focusing on their practicality and efficiency in point-of-need scenarios. By considering criteria such as ease of use, turnaround time, and robustness in handling different sample matrices, we aimed to highlight the critical factors that influence the selection of an appropriate extraction method for immediate and reliable diagnostic outcomes in diverse settings. The effectiveness of each protocol was evaluated by comparing the time threshold and fluorescence signal using isothermal amplification (namely reverse transcription-recombinase-aided amplification). For comparison, samples were also extracted with Qiagen spin column extraction.

Results

The performance of each protocol in extracting feline Coronavirus (FCoV) RNA differed depending on the sample type, such as nasal swab, serum, and feces. Overall, protocol VIII proved to be flexible and reliable for point-of-need diagnostics owing to its consistent extraction efficiency across different sample types and its excellent sensitivity (2 × 101 RNA copies/μL from supernatant and nasal swab and 2 × 102 RNA copies/μL from serum).

Conclusion

This study emphasizes the significance of considering the specific sample type and diagnostic goal in selecting the right extraction protocol.

在快速发展的分子诊断领域,确定一种合适的提取方法对于确定定点设备的适用性至关重要。提取作为诊断过程的第一步和重要步骤,对检测病原体的准确性、可靠性和速度起着至关重要的作用。提取方法的范围从传统的有机提取方法到现代的先进方法,如基于磁珠的分离,每种方法都有其独特的优点和局限性。方法本研究探讨了10种商用协议(用I-X表示)的比较有效性,重点关注它们在需求点场景中的实用性和效率。通过考虑诸如易用性、周转时间和处理不同样品矩阵的稳健性等标准,我们旨在强调在不同环境中影响选择适当提取方法以获得即时和可靠诊断结果的关键因素。通过等温扩增(即逆转录重组酶辅助扩增)比较时间阈值和荧光信号来评估每种方案的有效性。为了比较,还采用Qiagen自旋柱萃取法提取样品。结果不同方法提取猫冠状病毒(FCoV) RNA的效果因样品类型(如鼻拭子、血清和粪便)而异。总体而言,由于其在不同样品类型中具有一致的提取效率和出色的灵敏度(来自上清和鼻拭子的2 × 101 RNA拷贝/μL和来自血清的2 × 102 RNA拷贝/μL),第八方案被证明是灵活可靠的。结论本研究强调了在选择合适的提取方案时考虑具体的样品类型和诊断目标的重要性。

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease that results from SFTS bunyavirus (SFTSV) infection. Infection with SFTSV can activate the immune system, producing a series of inflammatory factors. Some patients, particularly those with pre-existing conditions or at an advanced age, may experience an excessive inflammatory response, triggering systemic multi-organ failure progressing to severe disease and, potentially, death. In recent years, extensive research has been conducted on the mechanism of SFTSV infection and its interaction with host immune responses. Additionally, a range of biomarkers with significant prognostic value for SFTS have been identified. This review provides a comprehensive summary of the latest advancements in understanding the interplay between SFTSV and host immune responses, and elucidates the role of these biomarkers in the early detection of severe cases and fatal outcomes. The insights presented aim to inform strategies for early intervention, clinical treatment, and prognostic assessment of patients with SFTS.

发热伴血小板减少综合征(SFTS)是由发热伴血小板减少综合征布尼亚病毒(SFTSV)感染引起的新发传染病。感染SFTSV可激活免疫系统,产生一系列炎症因子。一些患者,特别是那些已有疾病或高龄患者,可能会出现过度的炎症反应,引发全身性多器官衰竭,进而发展为严重疾病,并可能导致死亡。近年来,人们对SFTSV感染的机制及其与宿主免疫应答的相互作用进行了广泛的研究。此外,已经确定了一系列对SFTS具有重要预后价值的生物标志物。本文综述了SFTSV与宿主免疫应答之间相互作用的最新进展,并阐明了这些生物标志物在早期发现严重病例和致命结局中的作用。提出的见解旨在为SFTS患者的早期干预、临床治疗和预后评估提供信息。

Background

Few studies have explored the association between lipoprotein-associated phospholipase A2 (Lp-PLA2) and systemic lupus erythematosus (SLE). However, most of these studies have investigated only European patient populations and have come to contradictory conclusions. Furthermore, few studies have been conducted on Chinese patient groups. This study aimed to explore the association between serum Lp-PLA2 activity and SLE in a Chinese patient group.

Methods

Serum Lp-PLA2 activity was detected in 154 SLE patients and 55 age-, sex-, and body mass index-matched healthy controls. Information concerning the anthropometric data, clinical manifestations, SLE Disease Activity Index 2000 (SLEDAI-2K), complement C3 (C3), and complement C4 (C4) erythrocyte sedimentation rate (ESR), and autoantibodies were evaluated.

Results

The average level of serum Lp-PLA2 activity was 221 ± 56 U/L in SLE patients compared with 160 ± 37 U/L in healthy controls (p < 0.001). SLE patients that presented with nephritis, anemia, and fibrinolytic abnormality had higher serum Lp-PLA2 activity than SLE patients who did not present with these symptoms (p < 0.05), and the levels of serum Lp-PLA2 activity correlated with the severity of the clinical manifestations (p < 0.001). There was no correlation between serum Lp-PLA2 activity and serum autoantibodies levels (p > 0.05). According to Spearman’s rank correlation coefficient, ESR, SLEDAI-2K, C3, and C4 significantly correlated with serum Lp-PLA2 activity (p < 0.001). According to binary logistic regression, Lp-PLA2 activity was independently associated with active SLE in patients (OR 1.049; 95% CI: 1.025–1.073, p < 0.001).

Conclusions

Serum Lp-PLA2 activity is associated with some clinical manifestations (nephritis, anemia, and fibrinolytic abnormality) in SLE patients, and its activity may contribute to the development of SLE disease. These findings provide new insight into the pathogenesis of SLE.

很少有研究探讨脂蛋白相关磷脂酶A2 (Lp-PLA2)与系统性红斑狼疮(SLE)之间的关系。然而,这些研究大多只调查了欧洲的患者群体,并得出了相互矛盾的结论。此外,对中国患者群体的研究较少。本研究旨在探讨血清Lp-PLA2活性与中国患者SLE之间的关系。方法对154例SLE患者和55例年龄、性别和体重指数匹配的健康对照进行血清Lp-PLA2活性检测。评估有关人体测量数据、临床表现、SLE疾病活动指数2000 (SLEDAI-2K)、补体C3 (C3)和补体C4 (C4)红细胞沉降率(ESR)和自身抗体的信息。结果SLE患者血清Lp-PLA2平均水平为221±56 U/L,健康对照组为160±37 U/L (p <;0.001)。出现肾炎、贫血和纤溶异常的SLE患者血清Lp-PLA2活性高于未出现这些症状的SLE患者(p <;血清Lp-PLA2活性水平与临床表现严重程度相关(p <;0.001)。血清Lp-PLA2活性与血清自身抗体水平无相关性(p >;0.05)。根据Spearman等级相关系数,ESR、SLEDAI-2K、C3、C4与血清Lp-PLA2活性显著相关(p <;0.001)。根据二元logistic回归,Lp-PLA2活性与患者活动性SLE独立相关(OR 1.049;95% CI: 1.025-1.073, p <;0.001)。结论血清Lp-PLA2活性与SLE患者的一些临床表现(肾炎、贫血、纤溶异常)有关,其活性可能参与SLE疾病的发展。这些发现为SLE的发病机制提供了新的认识。

Background

Knee osteoarthritis (KOA) is a chronic degenerative joint disease that frequently occurs in middle-aged and older individuals. Although celecoxib is a commonly used drug for the treatment of KOA, its efficacy and safety have limitations. Zushima, a traditional Chinese medicine, is commonly used for treating joint pain and has anti-inflammatory and analgesic properties. This study aims to explore the effect of the Zushima patch combined with celecoxib on pain and inflammatory factor expression in knee osteoarthritis (KOA) patients with cold-dampness obstruction.

Methods

A total of 100 patients with KOA of cold-dampness obstruction were randomly divided into a treatment group (n = 50) and a control group (n = 50). Patients in the control group received oral administration of celecoxib capsules, whereas the treatment group received the Zushima patch combined with oral administration of celecoxib capsules. Then, the efficacy and safety were compared, together with the traditional Chinese medicine (TCM) syndrome score, pain, and knee joint function. We also determined the concentrations of osteoprotegerin (OPG), insulin-like growth factor (IGF-1), osteocalcin (OC), and inflammatory factors such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and C-reactive protein (CRP). Finally, the safety between the two groups was compared.

Results

The total effective rate in the treatment group was significantly higher than that in the control group. After treatment, the levels of the TCM syndrome score, pain score, IL-1, IL-6, and CRP in the treatment group showed significant decreases compared with those in the control group, while the scores of OPG, IGF-1, OC, and knee joint function in the treatment group showed significant increases compared with those in the control group. There was no significant difference in adverse events between the two groups.

Conclusions

The Zushima patch combined with celecoxib could relieve the pain of KOA with cold-dampness obstruction and improve knee joint function. These effects may be the result of the downregulation of inflammatory factors and the regulation of joint fluid-related indices.

膝关节骨性关节炎(KOA)是一种常见于中老年人的慢性退行性关节疾病。虽然塞来昔布是治疗KOA的常用药物,但其疗效和安全性存在局限性。足岛是一种传统的中药,通常用于治疗关节疼痛,具有抗炎和镇痛的特性。本研究旨在探讨足岛贴片联合塞来昔布对寒湿梗阻膝骨关节炎(KOA)患者疼痛及炎症因子表达的影响。方法将100例寒湿梗阻KOA患者随机分为治疗组(n = 50)和对照组(n = 50)。对照组给予口服塞来昔布胶囊,治疗组给予足岛贴片联合口服塞来昔布胶囊。然后比较两组患者的疗效和安全性,并结合中医证候评分、疼痛和膝关节功能进行比较。我们还测定了骨保护素(OPG)、胰岛素样生长因子(IGF-1)、骨钙素(OC)和炎症因子如白细胞介素-1β (IL-1β)、白细胞介素-6 (IL-6)和c反应蛋白(CRP)的浓度。最后比较两组间的安全性。结果治疗组总有效率显著高于对照组。治疗后,治疗组中医证候评分、疼痛评分、IL-1、IL-6、CRP水平均较对照组显著降低,OPG、IGF-1、OC、膝关节功能评分均较对照组显著升高。两组不良事件发生率无显著差异。结论足岛贴片联合塞来昔布可减轻寒湿梗阻膝关节炎的疼痛,改善膝关节功能。这些作用可能是炎症因子下调和关节液相关指数调节的结果。

Background

Latent tuberculosis infection (LTBI) is a significant source of active tuberculosis (ATB), yet distinguishing between them is challenging because specific biomarkers are lacking.

Methods

We analyzed four microarray datasets (GSE19491, GSE37250, GSE54992, GSE28623) from the gene expression omnibus to identify differentially expressed genes (DEGs). Using protein–protein interaction (PPI) networks and LASSO-SVM algorithms, we selected three candidate biomarkers and evaluated their diagnostic efficacy. The expression levels of core genes were validated by RNA sequencing of healthy, ATB, and LTBI groups in a real-world cohort. We conducted Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses, predicted shared upstream miRNAs, constructed miRNA–hub and transcription factor (TF)–hub gene networks, and performed immune infiltration analysis.

Results

Three hub genes (SERPING1, C1QC, C1QB) were identified from 45 DEGs by PPI networks and machine learning screening. The diagnostic model based on the three hub genes had an area under the curve (AUC) value of 0.843 in the training set GSE19491 and 0.865 in the validation set GSE28623. Real-world transcriptome sequencing confirmed the expression trends of the hub genes across healthy, LTBI, and ATB groups. GO analysis showed that the 45 hub genes were primarily associated with immune inflammatory responses and pattern recognition receptors, whereas KEGG analysis indicated enrichment in complement and coagulation cascades. The miRNA–hub and TF–hub gene network analysis identified nine miRNAs and the zinc finger TF GATA2 as potential co-regulators of SERPING1, C1QC, and C1QB. Immune cell infiltration analysis identified significant differences in the immune microenvironment between LTBI and ATB, with macrophages and natural killer cells showing significant correlations with tuberculosis infection.

Conclusion

The diagnostic model with SERPING1, C1QC, and C1QB shows promise in distinguishing LTBI from ATB, indicating its potential as a diagnostic tool.

潜伏结核感染(LTBI)是活动性结核(ATB)的重要来源,但由于缺乏特定的生物标志物,区分它们具有挑战性。方法分析基因表达综合数据库中4个基因芯片数据集(GSE19491、GSE37250、GSE54992、GSE28623),鉴定差异表达基因。利用蛋白-蛋白相互作用(PPI)网络和LASSO-SVM算法,我们选择了三个候选生物标志物,并评估了它们的诊断效果。核心基因的表达水平通过现实世界队列中健康、ATB和LTBI组的RNA测序进行验证。我们进行了基因本体(Gene Ontology)和京都基因与基因组百科全书(KEGG)通路富集分析,预测了共享的上游mirna,构建了miRNA-hub和转录因子(TF) -hub基因网络,并进行了免疫浸润分析。结果通过PPI网络和机器学习筛选,从45个基因中鉴定出3个中心基因(SERPING1、C1QC、C1QB)。基于三个枢纽基因的诊断模型在训练集GSE19491和验证集GSE28623的曲线下面积(AUC)分别为0.843和0.865。真实世界转录组测序证实了枢纽基因在健康、LTBI和ATB组中的表达趋势。GO分析显示,45个枢纽基因主要与免疫炎症反应和模式识别受体相关,而KEGG分析显示补体和凝血级联富集。miRNA-hub和TF - hub基因网络分析发现,9个mirna和锌指TF GATA2可能是SERPING1、C1QC和C1QB的共同调节因子。免疫细胞浸润分析发现,LTBI和ATB的免疫微环境存在显著差异,巨噬细胞和自然杀伤细胞与结核感染存在显著相关性。结论基于SERPING1、C1QC和C1QB的诊断模型在区分LTBI和ATB方面有良好的前景,表明其作为诊断工具的潜力。
