Objective To analyze the epidemiological and spatial clustering characteristics of varicella in Changzhou from 2018 to 2024, and to provide a theoretical support for the formulation of prevention and control measures. Methods The reported case information of varicella in Changzhou from 2018 to 2024 was collected through the China Information System for Disease Control and Prevention, and the three-dimensional distribution characteristics were analyzed. The incidence trend was analyzed by Joinpoint regression, and the spatial autocorrelation analysis was performed by Arc GIS 10.5 software. The spatiotemporal scanning analysis was carried out with SaTScan 10.1.2 software. Results From 2018 to 2024, a total of 42,132 cases of varicella were reported in Changzhou, with an average annual incidence of 116.25/100,000. The reported incidence showed a downward trend, with an annual percentage change (APC) of -21.96% (95%C1: -32.63%~-9.33%, P<0.01). The incidence showed a “bimodal distribution”, and the age group was mainly under 15 years old (29,086 cases, accounting for 69.04%). The difference in incidence between men and women was statistically significant (χ2= 92.83, P<0.001), and the incidence gradually decreased with age ( χ2trend=112771.44, P<0.001). Global autocorrelation analysis showed that there was spatial aggregation in the six years (P<0.05), and local autocorrelation analysis showed that most of the towns (streets) in the three central urban areas of Tianning District, Zhonglou District, and Xinbei District, as well as some towns (streets) in Liyang City, Wujin District, and Economic Development Zone were high-high aggregation areas. Spatiotemporal scanning analysis showed that the first type of aggregation area was most of the towns (streets) in Tianning District, Zhonglou District and Xinbei District (23, accounting for 92%), and some towns (streets) in Wujin District and Economic Development Zone (RR=3.76, P<0.001), and the second type of aggregation area was most of the towns (streets) in Liyang City (7, accounting for 70%) (RR=3.66, P<0.001). Conclusion The reported incidence of varicella in Changzhou City shows a downward trend, with multiple spatial and temporal clusters. The prevention and control of varicella in high-risk clustering areas, peak hours and high-risk populations should be strengthened, and intervention measures should be taken as soon as possible.

Aberrant activation of glycolysis represents a key metabolic mechanism underlying the initiation and progression of nasal inflammation. Allergic rhinitis, chronic rhinosinusitis, and vasomotor rhinitis exhibit distinct etiologies, yet all are characterized by inflammatory responses, impaired epithelial barrier function, and neurovascular dysregulation, in which glycolytic metabolic reprogramming acts as a central hub connecting immunometabolism and inflammatory regulation.Recent evidence indicates that glycolysis-dependent activation of immune cells provides the essential energy basis for inflammatory onset. In dendritic cells, eosinophils, mast cells, and Th2 cells, the expression of key glycolytic enzymes including HK2, PKM2, and LDHA is upregulated, thereby promoting cellular activation and proinflammatory cytokine release via the mTOR-HIF-1α signaling axis. Notably, the metabolic reprogramming of eosinophils prolongs their survival and enhances the release of cytotoxic granules, while in mast cells, enhanced glycolysis facilitates IgE-mediated degranulation and histamine release. Furthermore, glycolysis also influences the Th17/Treg balance, with enhanced glycolytic flux promoting Th17 differentiation and contributing to the heterogeneous inflammatory profiles observed across different rhinitis subtypes.As a central metabolite, lactate contributes to the formation of a metabolism-inflammation vicious cycle through multiple mechanisms. Lactate acidifies the local microenvironment to activate TRPV1 channels and facilitate neuropeptide release, mediates immune cell chemotaxis through GPR81, and regulates gene expression via histone lactylation, thereby sustaining proinflammatory gene transcription. These lactate-mediated processes collectively amplify local inflammation and contribute to the persistence of nasal symptoms.Glycolytic reprogramming in epithelial cells is modulated by the EGF/EGFR pathway, and its dysregulation may result in disrupted tight junctions, abnormal goblet cell hyperplasia, and subsequent tissue remodeling. Substance P and calcitonin gene-related peptide released from sensory neurons, in conjunction with metabolic products, synergistically maintain persistent inflammatory stimulation by activating mast cells, forming a neuro-immune-metabolic regulatory network that drives disease chronicity.From a therapeutic perspective, glycolytic inhibitors such as 2-deoxyglucose, FX11, and 3-bromopyruvate exert anti-inflammatory effects by targeting key enzymes including HK2 and LDHA, each with distinct mechanisms: 2-DG competitively inhibits hexokinase, FX11 selectively targets LDHA to reduce lactate production, and 3-BrPA modulates multiple glycolytic enzymes. Moreover, traditional Chinese medicine formulas, monomeric active components, and small-molecule compounds have shown promising potential in alleviating nasal inflammation by regulating the mTOR-HIF-1α axis, exerting antioxidant effects, and modulating endoplasmic reticulum stress pathways. The multi-target characteristics of these natural products offer advantages in addressing the complex pathophysiology of nasal inflammatory diseases.Despite these advances, several challenges remain. The non-selective inhibition of glycolysis may interfere with epithelial repair and mucosal regeneration, leading to delayed wound healing. Technical limitations in dynamic metabolic monitoring and sampling precision hinder the accurate assessment of local nasal metabolism. Furthermore, current animal models, which predominantly rely on acute stimulation protocols, inadequately recapitulate the chronic tissue remodeling processes characteristic of human rhinitis.This review systematically summarizes glycolysis as a common metabolic node shared by different rhinitis subtypes, offering a novel theoretical basis for the development of precision therapeutic strategies targeting metabolic reprogramming.

OBJECTIVE To explore the antidepressant mechanism of Wenyang jieyu granules (WYJYG) via the NOD-like receptor thermal protein domain associated protein 3 (NLRP3)/apoptosis-associated speck-like protein containing a CARD (ASC)/Caspase-1 pathway. METHODS A rat model of depression was established by chronic unpredictable mild stress combined with single-housing for 42 consecutive days.The experiment set up blank group, model group, MCC950 (NLRP3 inflammasome inhibitor) group (10 mg/kg), fluoxetine group (positive control,2.08 mg/kg),low-dose WYJYG(3.78 g/kg) and high-dose WYJYG group (7.56 g/kg),with 10 rats in each group. From the 22nd day of the experiment, rats in the fluoxetine group, low-dose and high-dose WYJYG groups were intragastrically administered with the corresponding drugs and intraperitoneally injected with an equal volume of normal saline. Rats in the MCC950 group were intraperitoneally injected with MCC950 at the corresponding concentration and intragastrically administered with an equal volume of distilled water. Rats in the blank group and model group were given an equal volume of distilled water by gavage and an equal volume of normal saline by intraperitoneal injection. All interventions were performed once a day for 21 consecutive days. Behavioral tests were conducted once a week. After the last administration, the contents of ASC, ionized calcium binding adaptor molecule 1 (Iba1), interleukin-1β (IL-1β), and IL-18 in hippocampal tissues were detected. The protein expressions of NLRP3, cluster of differentiation 68 (CD68), Caspase-1, B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein were determined, and neuronal apoptosis was observed. RESULTS After the last administration, compared with the model group, the open-field activity time was significantly prolonged ( P <0.05), and the latency to feed in a novel environment was significantly shortened ( P <0.05) in rats of the high-dose WYJYG group. In hippocampal tissue, the contents of ASC, Iba1, IL-1β, and IL-18, as well as the protein expression levels of NLRP3, Caspase-1, and CD68, and the positive rate of neuronal apoptosis were all significantly decreased/downregulated ( P <0.05). Bcl-2 protein expression was significantly upregulated ( P <0.05), and the density of neuronal apoptosis-positive cells was significantly reduced ( P <0.05). CONCLUSIONS WYJYG play on antidepressant role by inhibiting the NLRP3/ASC/Caspase-1 pathway, reducing microglia-mediated neuroinflammation, and inhibiting hippocampal neurons apoptosis.

AIM:To evaluate the characteristics of ocular biometric parameters and the distribution of corneal astigmatism(CA)in patients with high myopia before cataract surgery.METHODS:A prospective cross-sectional study was conducted, and 695 cataract patients(695 eyes)with high myopia [defined as an axial length(AL)≥26.00 mm] scheduled to undergo cataract surgery at our hospital from January 2022 to December 2024 were consecutively enrolled, another 695 cataract patients(695 eyes)with normal ALs(22.00 mm ≤AL≤25.00 mm)who underwent cataract surgery at our hospital during the same period were included in the control group. For patients with both eyes eligible, the right eye was used for analysis. Before cataract surgery, IOL Master 700 was used to measure the ocular biometric parameters of both eyes for each patient in the two groups. The medical records and ocular biometric data in the two groups were recorded and collected.RESULTS:There were no statistically significant differences between the two groups in genger, age, corneal diameter, and central corneal thickness(all P>0.05). In the high myopia group, the mean AL was 29.20±2.61 mm, and 252 eyes(34.1%)had AL ≥30.00 mm(extremely high myopia). The mean anterior chamber depth(ACD), lens thickness, vitreous chamber depth(VCD), CA, AL/corneal radius of curvature and VCD/AL in the high myopia group were 3.45±0.40, 4.41±0.47, 21.34±2.60 mm, 1.18±0.78 D, 3.79±0.38, and 0.73±0.03, respectively, which were all greater than those in the control group(all P<0.01). In the high myopia group, 350 eyes(50.4%)had CA ≥1.00 D, 192 eyes(27.6%)had CA ≥1.50 D, and 94 eyes(13.5%)had CA ≥2.00 D, which were all higher than those in the control group(32.8%, 15.1%, and 6.6%, respectively; all P<0.001). In the high myopia group, 87 eyes(12.5%)had flat corneas, 424 eyes(61.0%)had moderate CA, and 40 eyes(5.8%)had high CA. These proportions were all higher than those in the control group(6.0%, 46.9%, and 2.9%, respectively; all P<0.001). In the high myopia group, ACD and ACD/AL were negatively correlated with AL(r=-0.162 and -0.661, respectively; all P<0.001), while both ACD and ACD/AL in the control group were positively correlated with AL(r=0.338 and 0.105, respectively; both P<0.01). In the high myopia group, CA increased with age when the patient's age was ≥50 years(r=0.197, P<0.001), which was consistent with the control group.CONCLUSION: The standardized ocular biometric data of cataract patients with high myopia before cataract surgery are helpful for ophthalmologists to accurately calculate the intraocular lens(IOLs)power and select the appropriate IOL type. The majority of high myopia patients need simultaneous correction of CA during cataract surgery.

INTRODUCTION:
Health literacy plays an essential role in one's ability to acquire and understand critical medical information in the coronavirus disease 2019 (COVID-19) infodemic and in other pandemics. We aimed to summarise the assessment, levels and determinants of pandemic-related health literacy and its associated clinical outcomes.
METHODS:
A systematic review was performed in Medline ® , Embase ® , PsycINFO ® , CINAHL ® and four major preprint servers. Observational and interventional studies that evaluated health literacy related to the novel COVID-19, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) were included. Items used in health literacy instruments were grouped under the themes of knowledge, attitudes and practices. Determinants of health literacy were grouped into five domains: sociodemographic, medical, psychological/psychiatric, health systems-related and others.
RESULTS:
Of the 2,065 articles screened, 70 articles were included. Of these, 21, 17 and 32 studies evaluated health literacy related to COVID-19, SARS and MERS, respectively. The rates of low pandemic health literacy ranged from 4.3% to 57.9% among medical-related populations and from 4.0% to 82.5% among nonmedical populations. Knowledge about the symptoms and transmission of infection, worry about infection, and practices related to mask usage and hand hygiene were most frequently evaluated. Sociodemographic determinants of health literacy were most frequently studied, among which higher education level, older age and female gender were found to be associated with better health literacy. No studies evaluated the outcomes associated with health literacy.
CONCLUSION
The level of pandemic-related health literacy is suboptimal. Healthcare administrators need to be aware of health literacy determinants when formulating policies in pandemics.

This study explores the therapeutic differences and mechanisms of salt-processed Phellodendri Chinensis Cortex in improving insulin resistance(IR) based on network pharmacology, molecular docking, and cellular experiments. The components and intersection targets of Phellodendri Chinensis Cortex in improving IR were collected from databases, and a "drug-component-target-disease" network and protein-protein interaction(PPI) network were constructed to screen core components and targets. A total of 29 active components and 240 intersection targets were identified, of which 13 were core targets. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses were used to identify key signaling pathways, and molecular docking was performed to validate the binding activity between core components and targets. An IR model in HepG2 cells was induced using insulin combined with high glucose, and the effects of Phellodendri Chinensis Cortex before and after salt-processing on cell glucose consumption were evaluated. The expression of proteins related to the mitogen-activated protein kinase(MAPK) and phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT) signaling pathways was detected by Western blot. The cellular experimental results showed that, compared with the model group, glucose consumption in the drug-treated groups was significantly increased(P<0.01), the phosphorylation level of extracellular regulated protein kinase(ERK) was decreased(P<0.05), the phosphorylation levels of PI3K and AKT were increased, and the expression of glucose transporter 4(GLUT4) was also upregulated(P<0.05). Furthermore, the effect of salt-processed Phellodendri Chinensis Cortex was better than that of raw Phellodendri Chinensis Cortex. The study demonstrates that Phellodendri Chinensis Cortex, both before and after salt-processing, improves IR by regulating the expression of related proteins in the MAPK and PI3K-AKT signaling pathways, with enhanced effects after salt-processing.

Hepatic ischemia/reperfusion injury (IRI) remains a critical complication contributing to graft dysfunction following liver surgery. As part of an ongoing search for hepatoprotective natural products, five previously unreported homoadamantane-type polycyclic polyprenylated acylphloroglucinols (PPAPs), named hyperhomanoons A-E (1-5), and one known analog, hypersampsone O (6), were isolated from Hypericum patulum. Among these, compound 6 demonstrated potent protective effects against CoCl₂-induced hypoxic injury in hepatocytes. Furthermore, in a murine model of hepatic IRI induced by vascular occlusion, pretreatment with 6 markedly alleviated liver damage and reduced hepatocyte apoptosis. This study is the first to identify PPAPs as promising scaffolds for the development of therapeutic agents targeting hepatic IRI, underscoring their potential as lead compounds in drug discovery efforts for ischemic liver diseases.

Since May 2022, a severe global Mpox epidemic has underscored the urgent need for a preventative vaccine. On September 16, 2022, the mainland of China reported its first case of imported Mpox, which was subsequently followed by a significant rise in domestic infections commencing from June 2023. This alarming trend has escalated the likelihood of localized outbreaks and covert transmission, posing a heightened risk to public health. Notably, the United States, many European countries, and Japan have approved the use of smallpox vaccines for Mpox prevention and emergency vaccination post-exposure, based on their cross-protection efficacy. In recent years, virology research has broadened its scope to include investigations into various novel vaccine approaches, such as nucleic acid-based vaccines, protein subunit vaccines, and epitope peptide vaccines, and other related methodologies. This review offers a thorough examination of the current global landscape of Mpox prevalence, delves into the advancements in Mpox vaccine development, and highlights the progress achieved in Mpox vaccine research, serving as a valuable resource and providing technical insights essential for the effective prevention and control of Mpox.
