Objective: To analyze the trends in incidence and mortality of colorectal cancer in Jinhua City, Zhejiang Province from 2016 to 2024, and to predict the incidence and mortality from 2025 to 2027, so as to provide the evidence for improving regional colorectal cancer prevention and control strategies. Methods: Data on incidence and mortality of colorectal cancer in Jinhua City from 2016 to 2024 were collected through the Zhejiang Chronic Disease Surveillance Information Management System. The crude incidence and crude mortality were calculated, and standardized using the data from the Sixth National Population Census in 2010. Trends in incidence and mortality of colorectal cancer from 2016 to 2024 were analyzed using the average annual percent change (AAPC). A grey Markov model was constructed to predict the incidence and mortality of colorectal cancer from 2025 to 2027. Results: From 2016 to 2024, the crude incidence and standardized incidence of colorectal cancer in Jinhua City were 46.90/100 000 and 30.69/100 000, respectively, showing upward trends (AAPC=4.594% and 2.051%, both P<0.05). The crude mortality and standardized mortality were 17.47/100 000 and 10.36/100 000, respectively, and the trends were not statistically significant (both P>0.05). The standardized incidence and standardized mortality of colorectal cancer in males were higher than those in females (35.38/100 000 vs. 25.68/100 000, 11.96/100 000 vs. 8.57/100 000, both P<0.05). The crude incidence and crude mortality of colorectal cancer in the ≥80 years age group were the highest, at 220.04/100 000 and 186.86/100 000, respectively. From 2016 to 2024, the standardized incidence of colorectal cancer in males and females showed upward trends (AAPC=5.069% and 3.965%, both P<0.05), while the trends in standardized mortality were not statistically significant (all P>0.05). The crude incidence in the 70-<80 years age group showed an upward trend (AAPC=1.320%, P<0.05), and the crude mortality in the 40-<50 years age group showed a downward trend (AAPC=-3.756%, P<0.05). Trends in other age groups were not statistically significant (all P>0.05). The prediction results of the grey Markov model showed that the predicted values of crude incidence and crude mortality of colorectal cancer in the whole population would increase from 58.20/100 000 and 20.04/100 000 in 2025 to 61.70/100 000 and 21.26/100 000 in 2027. Conclusions From 2016 to 2024, the incidence of colorectal cancer in Jinhua City showed upward trends, while the mortality trend was stable. Males and the elderly aged ≥80 years are high-risk populations for colorectal cancer incidence and mortality. It is predicted that both crude incidence and crude mortality will increase from 2025 to 2027.

BACKGROUND: Children's respiratory health demonstrates particular sensitivity to air pollution. Existing evidence investigating the association between short-term ozone (O₃) exposure and childhood pneumonia remains insufficient and inconsistent, especially in low- and middle-income countries (LMICs). METHOD: To provide more reliable and persuasive evidence, we implemented a multi-city, time-stratified case-crossover design with a large sample size, using data from seven representative children's hospitals across major geographical regions in China. To avoid the impact of the COVID-19 pandemic, individual-level medical records of inpatient children under 6 years of age diagnosed with pneumonia during 2016-2019 were collected. Conditional logistic regression models were fitted for each city, and city-specific estimates were pooled through a meta-analysis using a random-effects model. RESULTS: In total, the study included 137,470 pediatric pneumonia hospital admissions. The highest pooled estimate for O₃ occurred at lag0-1, with a 10 µg/m³ increase in O₃ associated with a 1.57% (95% CI: 0.67%-2.48%) higher risk of pediatric pneumonia hospital admissions. Stratified analyses indicated that the effects of O₃ were robust across different sexes, age groups, and admission seasons. We also observed a statistically significant increase in risk associated with O₃ concentrations exceeding the World Health Organization Air Quality Guidelines (WHO-AQGs). CONCLUSIONS This study revealed a significant positive association between O₃ and pediatric pneumonia hospital admissions. Our findings substantially strengthen the evidence base for the adverse health impacts of O₃, underscoring the importance of O₃ pollution control and management in reducing the public health burden of pediatric pneumonia.

Objective To investigate and analyze the occupational stress levels and influencing factors among radiation workers in China, and provide a reference for alleviating occupational stress and promoting mental health. Methods Using the general situation questionnaire, Effort-Reward Imbalance questionnaire, and radiation protection knowledge questionnaire, a convenience sampling method was adopted to investigate the occupational stress of 243 radiation workers in Liaoning, Fujian, Guangdong, and Xinjiang provinces. The independent samples t-test, one-way analysis of variance, chi-square test, and binary logistic regression were used to analyze the influencing factors. Results The average score of Effort-Reward Imbalance was 0.97 ± 0.22, and 100 (41.15%) radiation workers had occupational stress. There were significant differences in the detection rate of occupational stress among radiation workers of different ages, working years in radiation positions, monthly incomes, daily sleep durations, and daily working hours (P < 0.05). Logistic regression analysis identified daily working hours as a factor contributing to occupational stress. Conclusion The occupational stress among radiation workers in China is relatively severe. It is recommended to pay attention to the associated risks and implement targeted intervention measures to reduce the impact of occupational stress.

[Purpose]To analyze the trends of incidence and age at onset of leukemia in Jiangsu cancer registration areas from 2009 to 2019.[Methods]The continuous monitoring data of leukemia from 2009 to 2019 were collected from 16 cancer registries in Jiangsu Province.All datasets were checked and evaluated based on data quality control criteria and were included in the analysis.Crude incidence rate(CIR),age-standardized incidence rate by Chinese standard population(ASIRC),the average annual percentage change(AAPC),the standardized average age at onset,the changes in the age structure of incidence and the changes in the birth cohort by year were calculated.[Results]The incidence rate of leukemia significantly increased from 5.22/105 in 2009 to 7.88/105 in 2019,with a significant upward trend(for CIR,AAPC=4.95％,95％CI:3.82％～6.09％;for ASIRC,AAPC=2.97％,95％CI:1.52％～4.43％).The incidence rates were in-creased in all age groups and increased with the birth cohort by years.There was a tendency of backward shift for the age composition of the population,with the increasing of composition for those over 60 years old.The mean age at onset increased from 48.62 years old in 2009 to 57.96 years old in 2019,with a backward shift in the mean age(β=0.773,P＜0.001),and the mean age at onset increased with the year only in rural areas after standardization(β=0.428,P=0.017).[Conclusion]Leukemia incidence rate in Jiangsu Province increased from 2009 to 2019,and the age at onset has shifted backwards.It's important to strengthen the early prevention and control of leukemia.

Objective: To analyze the trends in incidence and mortality of prostate cancer in Jinhua City, Zhejiang Province from 2016 to 2024, so as to provide the evidence for the improvement of prostate cancer prevention and control measures. Methods: The incidence and mortality data of prostate cancer in Jinhua City from 2016 to 2024 were collected from the Chronic Disease Surveillance Information Management System of Zhejiang Province, and the crude incidence and mortality were calculated. The Chinese Sixth National Population Census in 2010 was used to calculate standardized incidence and mortality. The trends in incidence and mortality of prostate cancer were evaluated using average annual percent change (AAPC). Results: A total of 8 357 cases of prostate cancer were diagnosed in Jinhua City from 2016 to 2024. The crude incidence and standardized incidence were 37.36/100 000 and 21.17/100 000, respectively, showing upward trends (AAPC=16.275%, 12.511%, both P<0.05). There were 1 615 deaths of prostate cancer, and the crude mortality was 7.22/100 000, showing an upward trend (AAPC=5.451%, P<0.05). The standardized mortality was 3.49/105, and the trend showed no statistically significant (P>0.05). There were 28 cases of prostate cancer in individuals under 50 years old, accounting for 0.34%. The crude incidence and crude mortality of patients aged ≥50 years increased with age (both P<0.05). From 2016 to 2024, the crude incidence of prostate cancer in the 50-<60, 60-<70, 70-<80, and ≥80 age groups showed upward trends (AAPC=17.849%, 14.704%, 12.654% and 8.081%, all P<0.05), and the 50-<60 age group increased more quickly. There was no significant change in the crude mortality of prostate cancer among different age groups (all P>0.05). Conclusion From 2016 to 2024, the incidence of prostate cancer in Jinhua City showed an upward trend and had a trend of becoming younger, while the mortality remained relatively stable.

Objective To investigate the mechanism by which Shenqi Xiaozheng Decoction-medicated serum regulates c-Myc/SLC1A5/GLS1 signaling axis to inhibit glutamine(Gln)metabolism and activate immunogenic cell death(ICD)in non-small cell lung cancer(NSCLC)cells.Methods A549 cells were divided into control group,model group,Shenqi Xiaozheng Decoction-medicated serum low-,medium-and high-dosage groups and positive control group.A Gln-dependent growth model was established,and cells were treated with different concentrations of Shenqi Xiaozheng Decoction-medicated serum or the SLC1A5 inhibitor V-9302.Cell proliferation was assessed by CCK-8,EdU and colony formation assays;Cell invasion and migration were evaluated using Transwell and wound-healing assays;intracellular Gln,glutathione(GSH),and α-ketoglutarate(α-KG)contents were determined by colorimetric assay;reactive oxygen species(ROS)contents were measured with fluorescent probes;Western blot was used to detect the protein expressions of E-cadherin,N-cadherin,c-Myc,SLC1A5 and GLS1;c-Myc/SLC1A5 colocalization and high mobility group box 1(HMGB1)expression were assessed by dual immunofluorescence staining;flow cytometry was used to evaluate calreticulin(CRT)exposure on the cell surface,and ATP and HMGB1 contents in cell supernatants were quantified by ELISA.Results Compared with the control group,the model group showed significantly increased A549 cell viability,EdU-positive rate and migration rate(P<0.05),as well as higher colony counts and invasion cell numbers(P<0.05);cellular Gln,GSH and α-KG contents were significantly elevated(P<0.05,P<0.01),while ROS content were not significantly different(P>0.05),E-cadherin protein expression significantly decreased,whereas the protein expressions of N-cadherin,c-Myc,SLC1A5 and GLS1 significantly increased(P<0.05,P<0.01).c-Myc and SLC1A5 colocalization was enhanced,HMGB1 expression was significantly increased(P<0.01),CRT exposure significantly increased(P<0.01),and ATP and HMGB1 contents in cell supernatant were significantly elevated(P<0.05,P<0.01).Compared with the model group,Shenqi Xiaozheng Decoction-medicated serum at different concentrations significantly inhibited Gln-stimulated A549 cell proliferation,migration and invasion in a dosage-dependent manner.Mechanistic studies indicated that Shenqi Xiaozheng Decoction could reduce Gln uptake and synthesis of its metabolic products GSH and α-KG,induce ROS accumulation,up-regulate protein expression of E-cadherin,down-regulate the protein expressions of N-cadherin,c-Myc,SLC1A5 and GLS1(P<0.05,P<0.01),and enhance CRT exposure,ATP release and HMGB1 secretion(P<0.01).Conclusion Shenqi Xiaozheng Decoction may exert a synergistic"metabolism-immunity"antitumor effect by inhibiting c-Myc/SLC1A5/GLS1 axis-mediated Gln uptake,inducing ROS accumulation,and activating ICD signaling.

Under the current situation of "low prevalence and low infection" of schistosomiasis in China, and to provide a basis for achieving the goal of eliminating schistosomiasis by 2030 proposed by the Healthy China Action (2019 - 2030) as scheduled, the Hunan Provincial Corps Hospital of the Chinese People's Armed Police Force established a schistosomiasis monitoring and early warning index system based on the previous studies on schistosomiasis early warning index system and the recent literature analysis, combined with the current potential risk factors affecting the transmission and prevalence of schistosomiasis, and organized two rounds of expert consultation and carried out project promotion meetings. The experts reached a consensus on the comprehensiveness and practicability of the index system, aiming to lay a solid foundation for construction of China's schistosomiasis prevention and control early warning system.

Objective To investigate the therapeutic effect of repeated transcranial magnetic stimulation(rTMS)combined with hydrogel feeding training on patients with dysphagia following subacute cerebral infarction,as well as its impact on swallowing function.Methods From February 2022 to February 2024,102 patients with dysphagia after subacute cerebral infarction treated in our hospital were selected and divided into control group,sham stimulation group and observation group,with 34 cases in each group.The control group received hydrogel feeding training,the sham stimulation group received sham stimulation on the basis of the control group,and the observation group received repeated transcranial magnetic stimulation on the basis of the control group.The swallowing function,quality of life,nerve function,neurotrophic factor,nutritional status,respiratory function,cerebral blood flow signal and clinical efficacy of the two groups were measured and compared.Results Compared with pre-treatment,the leak-aspiration score scale(PAS),NIHSS score,and pulse index(PI)were significantly reduced in all groups after treatment.Moreover,the observation group exhibited lower values than both the control group and the pseudostimulation group(P<0.05).In contrast,functional oral intake scale(FOIS),dysphagia-specific quality of life(SWAL-QOL)score,brain-derived neurotrophic factor(BDNF),nerve growth factor(NGF),insulin-like growth factor 1(IGF-1),hemoglobin(Hb),albumin(ALB),forced vital capacity(FVC),one-second forced expiratory volume(FEV1),peak expiratory flow(PEF),peak systolic velocity(PSV),end-diastolic velocity(EDV),and mean velocity(MV)were significantly increased after treatment compared to pre-treatment.The observation group demonstrated higher values for these parameters compared to the control group and pseudostimu-lation group(P<0.05).Additionally,the clinical efficacy in the observation group was significantly higher(P<0.05).Conclusion The combination of repeated transcranial magnetic stimulation and hydrogel feeding training for patients with dysphagia following subacute cerebral infarction can effectively enhance swallowing function,mitigate nerve damage,and improve both nutritional status and quality of life.

Objective:To explore the latent trajectory class of perioperative pain catastrophizing in patients undergoing lumbar internal fixation surgery and analyze the influencing factors of these latent classes.Methods:A total of 180 patients who underwent lumbar internal fixation surgery at Xinxiang Central Hospital from January to December 2023 were selected using convenience sampling. The Pain Catastrophizing Scale (PCS) was used to assess pain catastrophizing at 1 day preoperatively and on postoperative days 3, 7, and 14. Latent Class Growth Modeling (LCGM) was employed to identify trajectory classes of pain catastrophizing, and Logistic regression analysis was used to examine their influencing factors.Results:A total of 177 patients completed the follow-up, with a follow-up rate of 98.33% (177/180) . The overall perioperative PCS score was (30.39±10.86) . PCS scores at 1 day preoperatively and on postoperative days 3, 7, and 14 were (37.63±6.23) , (33.27±6.00) , (28.55±9.02) , and (23.81±9.33) , respectively. The proportions of patients with PCS≥38 at the four times were 42.94% (76/177) , 23.16% (41/177) , 22.60% (40/177) , and 12.43% (22/177) , respectively. LCGM identified three latent trajectory classes of perioperative pain catastrophizing: "high-level declining group" (55.93%, 99/177) , "high-level fluctuating group" (28.81%, 51/177) , and "persistent high-level group" (15.25%, 27/177) . Logistic regression analysis showed that payment method, surgical duration, and preoperative PCS score were significant influencing factors of pain catastrophizing trajectory classes ( P<0.05) . Conclusions:Pain catastrophizing levels in patients undergoing lumbar internal fixation surgery peaked preoperatively. While most patients showed a declining trend postoperatively, a subset exhibited fluctuating or persistently high levels. Payment method, surgical duration, and preoperative pain catastrophizing levels significantly influenced the trajectory of pain catastrophizing, warranting attention from clinical nursing staff.

Objective:To investigate the hospitalization utilization of pneumoconiosis patients and its influencing factors in a northwestern city, and to provide theoretical basis for formulating service policies for pneumoconiosis patients.Methods:From March to October 2021. Existing living pneumoconiosis patients in kashgar were selected as the research objects. The "Survey Questionnaire on Medical Behaviors and Influencing Factors of Pneumoconiosis Patients" developed by the National Institute of Occupational Health and Poison Control of China Centers for Disease Control and Prevention was used to collect pneumoconiosis patients infomations from March to October 2021. This study investigated the demographic characteristics of pneumoconiosis patients, the types and stages of pneumoconiosis, as well as hospitalization in the past year, reasons for hospitalization, treatment measures, reasons for discharge. Additionally, it examined factors influencing medical behaviors, including medical insurance reimbursement, work-related injury insurance, and compensation situations.Logistics regression was used to analyze the influencing factors of hospitalization utilization.Results:The average age of the pneumoconiosis patients was elder with the age of 64.8. 86.7% (156/178) of them were retired, 75.8% (135/178) of them relied primarily on pensions for their income. The main types of pneumoconiosis were silicosis and coal workers' pneumoconiosis with the proportion of 57.3% (102/178) and 24.2% (43/178). 67.4% of them were stage I. The hospitalization rate in the year prior to the survey was 37.1%. The factors that promoted hospitalization were pension as the main source of income, pneumoconiosis in stage II, silicosis as the pneumoconiosis type, suffering joint pain, with two OR more other lung diseases (tuberculosis, cor pulmonale, COPD, pulmonary infection, bulla or pneumothorax, lung cancer, or mesothelioma) ( P<0.05) . Conclusion:The hospitalization rate of pneumoconiosis patients in the previous year was low. It is mainly influenced by the patient's economic income, the duration of pneumoconiosis, and the presence of comorbidities.
