In 2025, the American Cancer Society published "Cancer statistics, 2025", which projected cancer data for the upcoming year based on incidence data collected by central cancer registries (through 2021) and mortality data obtained from the National Center for Health Statistics (through 2022). Similarly, the National Cancer Center of China released "Cancer incidence and mortality in China, 2022" in December 2024, analyzing data from 22 cancer registries across the country. This study provides a comparative analysis of cancer incidence and mortality trends in China and the United States during the same period, with a focus on sex- and age-specific distributions and long-term changes in cancer patterns. Long-term trends indicate that lung and liver cancer mortality rates in China have declined, primarily due to tobacco control measures and hepatitis B vaccination programs. However, the burden of gastric and esophageal cancers remains substantial. In the United States, mortality rates for colorectal and lung cancers have continued to decline, largely attributed to widespread screening programs and advances in immunotherapy. As economic growth and social development, China’s cancer profile is gradually shifting towards patterns observed in countries with high human development index. However, the prevention and control of upper gastrointestinal cancers remains a critical public health challenge that requires further attention.

OBJECTIVES: To analyze the differential expression and biological functions of circRNAs in the anterior lens capsules of high myopic patients with cataract and their pathogenic roles in the development of this condition. METHODS: Anterior lens capsule specimens were collected intraoperatively from 36 patients with age-related cataract (ARC) and 36 high myopic patients with cataract. Among these, 18 specimens from each group were selected for whole transcriptome sequencing and biological analysis, and the remaining 36 specimens were used for validation of circPDGFRA, circFOXJ3, hsa_circ_0004767, hsa_circ_0007528, ciCRIM1, circMAN1A2, circSLC5A3, and circPTK2 expressions using RT-qPCR. hsa_circ_0007528 was selected for cell experiments to examine its effects on proliferation, migration, and apoptosis of lens epithelial cells (LECs). RESULTS: A total of 16 192 circRNAs were detected in the specimens from both groups, among which 62 circRNAs were differentially expressed (29 upregulated and 33 downregulated). GO and KEGG analyses revealed that the differentially expressed circRNAs were primarily localized in the cytoplasm, nucleoplasm, and endoplasmic reticulum, and were involved in signaling pathways associated with Gap junction and the PI3K-Akt, NF-κB, Jak-STAT, HIF-1, and MAPK signaling pathways. The ceRNA network predicted multiple target genes. RT-qPCR validation results were consistent with the sequencing data. In the LECs, upregulation of hsa_circ_0007528 significantly inhibited cell proliferation and migration and obviously promoted cell apoptosis. CONCLUSIONS The expression profile of circRNAs in the anterior lens capsule of high myopic patients with cataract differs from that of ARC patients. Upregulation of hsa_circ_0007528 inhibits LEC proliferation and migration and promotes cell apoptosis.

ObjectiveTo determine the prevalence and determinants of Mycobacterium tuberculosis latent infection among primary and secondary school students in Cixi City, Zhejiang Province, so as to provide references for the prevention and control of tuberculosis in school settings. MethodsInterferon-γ release assay (IGRA) testing was performed to fourth-grade primary school students , as well as to those grade 7 and grade 10 students of the academic year 2024‒2025 in Cixi City. Individuals tested positive for IGRA were subsequently subjected to chest X-ray examination and sputum tests (including three smear microscopy examinations and one mycobaterial culture), and epidemiological investigations were carried out for confirmed cases. Infection rates were compared across student categories by χ² tests, while factors influencing infection were analysed through multivariate logistic regression. ResultsA total of 36 214 students completed tuberculosis screening, with an infection rate of 0.72% (260/36 214). The tuberculosis infection rates among fourth-grade primary school students, non boarding grade 7 students, boarding grade 7 students, grade 10 students of senior high school and of vocational high school were 0.68% (89/13 139), 0.75% (86/11 501), 0.51% (13/2 553), 0.76% (52/6 819), and 0.91% (20/2 202), respectively. Multivariate logistic regression analyses indicated that students with a history of close contact with tuberculosis patients (OR=21.435, P<0.001) had a higher risk of tuberculosis infection, students with a geographic origin outside Zhejiang Province (OR=1.485, P=0.002) had a higher risk of infection than those within Zhejiang Province. Furthermore, students from ethnic minority classes (OR=4.232, P<0.001) might be high-risk groups for tuberculosis infection in high school settings. One IGRA-positive student was confirmed as bacteriologically positive pulmonary tuberculosis by liquid culture of sputum collected one month later. ConclusionSchools should prioritize tuberculosis screening. Students with a history of close contact, those with a geographic origin outside Zhejiang Province, and those enrolled in minority classes should be taken as priority targets for future tuberculosis screening programmes. A tracking and follow-up system must be established for IGRA-positive students to prevent persistent transmission of Mycobacterium tuberculosis within the school settings.

Objective:To investigate the molecular mechanisms of chronic rhinosinusitis (CRS), to identify key cell subgroups and genes, to construct effective diagnostic models, and to screen for potential therapeutic drugs.Methods:Key cell subgroups in CRS were identified through single-cell transcriptomic sequencing data. Essential genes associated with CRS were selected and diagnostic models were constructed by hdWGCNA (high dimensional weighted gene co-expression network analysis) and various machine learning algorithms. Causal inference analysis was performed using Mendelian randomization and colocalization analysis. Potential therapeutic drugs were identified using molecular docking technology, and the results of bioinformatics analysis were validated by immunofluorescence staining. Graphpad Prism, R, Python, and Adobe Illustrator software were used for data and image processing.Results:An increased proportion of basal and suprabasal cells was observed in CRS, especially in eosinophilic CRS with nasal polyps (ECRSwNP), with P=0.001. hdWGCNA revealed that the "yellow module" was closely related to basal and suprabasal cells in CRS. Univariate logistic regression and LASSO algorithm selected 13 key genes ( CTSC, LAMB3, CYP2S1, TRPV4, ARHGAP21, PTHLH, CDH26, MRPS6, TENM4, FAM110C, NCKAP5, SAMD3, and PTCHD4). Based on these 13 genes, an effective CRS diagnostic model was developed using various machine learning algorithms (AUC=0.958). Mendelian randomization analysis indicated a causal relationship between CTSC and CRS (inverse variance weighted: OR=1.06, P=0.006), and colocalization analysis confirmed shared genetic variants between CTSC and CRS (PPH4/PPH3>2). Molecular docking results showed that acetaminophen binded well with CTSC (binding energy:-5.638 kcal/mol). Immunofluorescence staining experiments indicated an increase in CTSC +cells in CRS. Conclusion:This study integrates various bioinformatics methods to identify key cell types and genes in CRS, constructs an effective diagnostic model, underscores the critical role of the CTSC gene in CRS pathogenesis, and provides new targets for the treatment of CRS.

Element doping is one of the strategies for increasing the activity of enzyme-like materials.In this study,cobalt,nitrogen and chlorine-doped carbon dots(Co,N,Cl-CDs)were prepared by one-step hydrothermal synthesis utilizing CoCl2 and glutamate as raw ingredients.In weakly acidic environments,Co,N,Cl-CDs exhibited high peroxidase-like activity and could catalyze the oxidation of 3,3′,5,5′-tetramethylbenzidine(TMB)by hydrogen peroxide into oxided TMB(oxTMB),resulting in a distinct color change.Free radical scavenging and electron spin resonance techniques were used to further investigate the catalytic reaction mechanism of Co,N,Cl-CDs,and the reactive intermediates produced during the reaction were identified as hydroxyl radical.Acid phosphatase(ACP)could catalyze the hydrolysis of sodium ascorbyl phosphate to release ascorbic acid,which could reduce the blue oxTMB into colorless TMB.Based on this principle,a colorimetric-switching sensing system for detection of ACP was developed by coupling Co,N,Cl-CDs and ACP.The sensing system demonstrated good linearity in ACP activity range of 0.5-20 U/L,with a detection limit of 0.17 U/L.The developed sensing system was used to detection of ACP in real serum samples with good recoveries(97.1%-105.7%)and reproducibility(RSD<5%).The sensing system developed here based on Co,N,Cl-CDs had many advantages such as low detection cost,process visualization,and high sensitivity,providing reference for detection of ACP.
