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.

Objective:To explore the correlation between grip strength promotion and improvement of body composition and metabolic disorders in health examination population of different genders.Methods:In this retrospective cohort study, clinical data of 600 people who received health examination and grip strength check-up two times or more in the Medical Examination Center of Peking University Third Hospital from January 2018 to November 2022 were selected. The general data, physical examination, biochemical parameters, body composition and grip strength results were collected. After the first physical examination, the grip strength test was conducted, appropriate resistance strength exercises were given based on individual evaluation results. A health lecture was held, and the information related to health exercise was pushed through WeChat official account every week. The grip strength test was completed at the same time at the second physical examination, and the difference between the two test results was calculated before and after the second physical examination. The generalized estimation equation was used to analyze the correlation between the improvement of grip strength and the improvement of body composition and metabolic disorders in different gender health-check population.Results:In man and women, the body mass index [(25.50±3.66) vs (25.33±3.74) kg/m 2, (22.41±3.55) vs (22.25±3.46) kg/m 2] and grip strength [(42.71±7.30) vs (41.77±7.36) kg, (25.28±5.30) vs (23.98±4.87) kg] at the second health check-up were all significantly higher than those at the first time, and the diastolic blood pressure [(72.79±10.30) vs (74.47±9.85) mmHg (1 mmHg=0.133 kPa), (66.93±8.90) vs (68.92±9.42) mmHg] and serum homocysteine [(17.96±14.09) vs (19.27±14.26) μmol/L, (9.47±3.91) vs (10.26±3.90) μmol/L] were all significantly lower than those at the first time (all P<0.05). Among man, the low-density lipoprotein cholesterol (LDL-C) at the second physical examination was significantly lower than that at the first time [(2.94±0.78) vs (3.00±0.69) mmol/L] (all P<0.05). Among women, the systolic blood pressure and uric acid at the second health check-up were both significantly lower than those at the first time [(109.34±12.85) vs (110.54±12.32) mmHg, (276.91±62.46) vs (287.16±68.78) μmol/L], and the waist-hip ratio was significant higher (85.8%±5.1% vs 85.4%±5.0%) (all P<0.05). In males, the decreased aspartate aminotransferase ( OR=0.932, 95% CI: 0.888-0.978) and the increased skeletal muscle index ( OR=75.370, 95% CI: 29.012-195.806) were both positively correlated with the elevation of grip strength (all P<0.05); and in females, the decreased homocysteine ( OR=0.876, 95% CI: 0.782-0.982) and glycosylated hemoglobin ( OR=0.423, 95% CI: 0.222-0.805) and increased skeletal muscle index ( OR=22.918, 95% CI: 11.114-47.256) were all positively correlated with the elevation of grip strength (all P<0.05). Conclusion:There is a positive correlation between the improvement of grip strength and the improvement trend of body composition and metabolic disorders in in health examination population of different genders.

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.

Objective To explore the effect of Mongolian medicine Naru-3 pills on the treatment of neuropathic pain(NP)with pregabalin combined with nerve block.Methods Forty-one hospitalized pa-tients in the department of pain medicine diagnosed with NP from October 2022 to September 2023 were se-lected,including 20 males and 21 females,aged 40-80 years,BMI≥18.5 kg/m2.The patients were di-vided into two groups by random number table method:Mongolian medicine Naru-3 pills group(observation group,n=20)and conventional treatment group(control group,n=21).The control group received conventional treatment:oral pregabalin capsule combined with ultrasound-guided nerve block in pain area.The observation group was added oral administration of Mongolian medicine Naru-3 pills(2 g/10 capsules)on the basis of conventional treatment,taking 3-5 capsules orally before going to bed every night for 2 weeks.The numerical rating scale(NRS)pain score,short-form McGill pain questionnaire(SF-MPQ)score,and Pittsburgh sleep quality index(PSQI)were recorded before treatment and 2 weeks,1 month,and 2 months after the treatment.The serum concentrations of IL-6,IL-8,IL-1β,and TNF-α were detected by enzyme-linked immunosorbent assay(ELISA)1 day before treatment and 2 weeks after treatment.Occur-rence of adverse reactions during treatment such as nausea,vomiting,bloating,palpitations,drowsiness,and dizziness were recorded.Results Compared with 1 day before treatment,NRS pain score,SF-MPQ score,and PSQI were lower in both groups 2 weeks,1 month,and 2 months after the treatment(P＜0.05),the serum concentrations of IL-6,IL-1β,and TNF-α were reduced in both groups 2 weeks after the treatment(P＜0.05).Compared with the control group,NRS pain score,SF-MPQ score,and PSQI were lower in the observation group 2 weeks,1 month,and 2 months after the treatment(P＜0.05);the serum concentrations of IL-6,IL-1 β,and TNF-α were reduced in the observation group 2 weeks after the treatment(P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion Mongolian Naru-3 pills combined with conventional therapy can effectively reduce the pain of NP patients,improve the quality of sleep of patients,and may have the effect of regulating neuroinflammation.
