Objective: To investigate the prevalence of overweight and obesity among children and adolescents in Yangzhou City, and its association with screen behaviors, so as to provide scientific evidence for weight management among students. Methods: In May 2025, an electronic questionnaire survey was conducted among children and adolescents in Yangzhou City. A total of 3 722 participants were selected from grades 4 to 12 in 18 primary and secondary schools (108 classes) by using stratified cluster random sampling. The Chi square test was used to compare the differences in the detection rates of overweight and obesity among children and adolescents with 5 types of screen behaviors (watching TV, playing electronic games, scrolling short videos, screen based learning, electronic socializing) in different time groups each day (never, >0~<2 h, ≥2 h). Multivariate Logistic regression analysis was performed to examine the associations of five types of screen behaviors, presence of electronic devices in the bedroom, and screen use during meals on the weight status of children and adolescents. Results: The prevalence of overweight and obesity among children and adolescents was 37.3%. For all five types of screen behaviors, the differences in the distribution of overweight and obesity detection rates among children and adolescents across the three time spent categories were statistically significant ( χ 2=30.76- 70.78 , all P <0.01). After adjusting for confounding factors, multivariate Logistic regression analysis revealed that frequent or always using screens during meals( OR =1.63, 95％ CI =1.14~2.31), playing video games ( OR =1.28, 95% CI =1.11-1.48), browsing short videos ( OR =1.29, 95％ CI=1.09-1.54), and screen based learning ( OR =1.26, 95％ CI =1.10-1.44) were significantly associated with overweight and obesity among children and adolescents (all P <0.05). Conclusions Excessive screen use is positively correlated with the incidence of overweight and obesity in children and adolescents. Targeted interventions on screen behaviors among children and adolescents are therefore warranted.

Objective To analyze the epidemiological characteristics of imported malaria cases in Guangxi Zhuang Autonomous Region from 2017 to 2024, so as to formulate the targeted control strategies for imported malaria. Methods The demographic and epidemiological data of malaria cases reported in Guangxi Zhuang Autonomous Region from 2017 to 2024 were collected through the China Disease Prevention and Control Information System. The source of malaria cases acquiring infections, composition of malaria parasite species, regional distribution of malaria cases, population characteristics of malaria cases, temporal distribution of malaria cases, time of diagnosis, deaths and institutions reporting malaria cases were statistically analyzed with a descriptive statistical method. Results A total of 1 308 malaria cases were reported in Guangxi Zhuang Autonomous Region from 2017 to 2024, and all cases were overseas imported cases, with no secondary cases identified. Plasmodium falciparum malaria (57.11%, 747/1 308) and P. ovale malaria (27.68%, 362/1 308) were two most common forms of malaria, and three deaths occurred among P. falciparum malaria cases. The number of malaria cases appeared an overall tendency towards a decline from 2017 to 2022, followed by a rise after 2023. The malaria cases predominantly acquired infections from Africa (1 284 cases, accounting for 98.17%), with Ghana (432 cases, accounting for 33.03%) and Cameroon (145 cases, accounting for 11.09%) as two most frequent origin countries, and P. falciparum malaria (58.02%, 745/1 284) was the predominant form of malaria among African imported malaria cases; however, P. vivax malaria cases comprised 89.58% (86/96) of all malaria cases derived from Ethiopia. In terms of regional distribution, malaria cases were highly concentrated in Nanning City (1 075 cases, accounting for 82.19%), with the most prominent situated in Shanglin County (903 cases, accounting for 69.04%), and these cases were predominantly found among individuals at ages of 20 to 59 years (1 280 cases, accounting for 97.86%), males (1 265 cases, accounting for 96.71%), and gold/coal mining workers (1 042 cases, accounting for 79.66%). In terms of temporal distribution, malaria cases were reported throughout the year, with the peak incidence in April (146 cases, accounting for 11.16%). The median duration from onset of disease to initial diagnosis was 1 (interquartile range, 2) day, and the median duration from initial diagnosis to definitive diagnosis was 1 (interquartile range, 1) day. Malaria cases were predominantly reported by medical institutions (1 075 cases, accounting for 82.19%), and the proportion of malaria cases reported by medical institutions increased from 75.92% in 2017 to 96.27% in 2024, while the proportion of malaria cases reported by disease control and prevention institutions reduced from 24.08% in 2017 to 3.73% in 2024. There was a significant difference in the proportion of malaria cases reported by medical institutions and disease control and prevention institutions from 2017 to 2024 (both P < 0.001). The 3 dead imported P. falciparum malaria cases predominantly received initial diagnosis at townshipand lower-level institutions (66.67%, 2/3), with 1 (interquartile range, 2) day median duration from onset of disease to initial diagnosis, 2 (interquartile range, 4) days median duration from initial diagnosis to definitive diagnosis, and 1 (interquartile range, 19) day median duration from definitive diagnosis to death. Conclusions Imported P. falciparum malaria from Africa is predominant among malaria cases in Guangxi Zhuang Autonomous Region, and malaria cases are highly concentrated in specific regions and among specific occupational groups. It is recommended to strengthen inter-departmental collaboration, implement refined management among labors going to Africa, improve the integration of medical treatment and disease prevention, and enhance the diagnosis and treatment of severe malaria cases.

Objective: To investigate the prevalence of co-occurrence of common diseases among junior high school students in Yunnan Province and to identify latent comorbidity patterns and analyze their associated factors, so as to provide evidence for the comprehensive prevention and control of common diseases among students. Methods: From September to November 2025, a stratified cluster sampling method was employed to survey 71 791 students in grades 7-9 recruited from 258 junior high schools in Yunnan Province. Information on six common diseases, including screening myopia, dental caries, overweight/obesity, malnutrition, elevated blood pressure, and abnormal spinal curvature, was collected through physical examinations and questionnaire surveys, along with data on demographic characteristics, physical activity, and sleep. Latent class analysis (LCA) was used to identify comorbidity patterns of common diseases, and multinomial Logistic regression was performed to analyze the factors associated with each pattern. Results: The detection rates of screening myopia, dental caries, overweight/obesity, elevated blood pressure, malnutrition, and abnormal spinal curvature among junior high school students were 65.2%, 62.1%, 22.4%, 10.9% , 8.2%, and 5.7%, respectively. LCA identified three latent comorbidity patterns of common diseases: a high prevalence screening myopia-dental caries-spinal curvature abnormality pattern (C1, 63.8%), an overweight/obesity elevated blood pressure pattern (C2, 24.1%), and a relatively low burden pattern (C3, 12.0%). With C3 as the reference, multinomial Logistic regression showed that girls were more likely than boys to be assigned to C1 and C2 [ OR (95% CI )=2.12(2.02-2.23), 1.31(1.23-1.38)]; non-Han students were less likely than Han students to belong to C1 and C2 [ OR (95% CI )=0.88(0.83-0.92), 0.81(0.77-0.86)]; students in grades 8 and 9 were more likely than those in grade 7 to belong to C1 and C2, with the highest likelihood observed among grade 9 students [ OR (95% CI )=1.43(1.35-1.52), 1.27(1.19-1.36)]; insufficient sleep was associated with increased odds of belonging to C1 and C2 [ OR (95% CI )=1.15(1.09-1.22), 1.25(1.18-1.33)] (all P <0.05). Compared with students who engaged in outdoor activities during breaks, those who stayed indoors, either inside the teaching building but outside the classroom or inside the classroom, were more likely to belong to C1 [ OR (95% CI )=1.09(1.02-1.16), 1.17(1.09-1.26)] and C2 [ OR (95% CI )=1.13(1.05-1.21), 1.25(1.15-1.35)]; students not living with their parents were less likely to belong to C1 and C2 [ OR (95% CI )=0.83(0.77-0.90), 0.74(0.68-0.81)] (all P <0.05). Conclusions The co-occurrence of common diseases is relatively prominent among junior high school students in Yunnan Province, with distinct latent stratification patterns. Tiered and precise comprehensive interventions should be implemented targeting key populations to promote the prevention and control of common diseases among students.

Objective: To analyze the mortality trend of chronic respiratory diseases in Lianyungang City, Jiangsu Province from 2011 to 2024, and predict the mortality from 2025 to 2029, so as to provide the evidence for developing forward-looking prevention and control strategies and targeted intervention measures. Methods: Chronic respiratory disease death surveillance data in Lianyungang City from 2011 to 2024 were collected through the Jiangsu Chronic Disease Management Information Platform. The crude mortality was calculated and standardized using the data of the Sixth National Population Census in 2010. Average annual percent change (AAPC) was used to analyze the mortality trends of chronic respiratory diseases by gender, region, and age in Lianyungang City from 2011 to 2024. The GM (1,1) grey model was established using the crude mortality of chronic respiratory diseases from 2011 to 2024 to predict the crude mortality of chronic respiratory diseases from 2025 to 2029. Results: From 2011 to 2024, the crude mortality and standardized mortality of chronic respiratory diseases in Lianyungang City were 52.20/105 and 36.57/105, respectively. The crude mortality and standardized mortality were 53.14/105 and 43.79/105 in males, respectively, which were higher than 51.17/105 and 30.14/105 in females (both P<0.05). The crude mortality and standardized mortality were 55.62/105 and 39.85/105 in rural areas, respectively, which were higher than 38.11/105 and 24.15/105 in urban areas (both P<0.05). From 2011 to 2024, the standardized mortality of chronic respiratory diseases showed downward trends in the total population, males, females, urban areas, and rural areas (AAPC=-6.956%, -5.175%, -8.659%, -4.290%, and -7.369%, all P<0.05). The crude mortality of chronic respiratory diseases in the total population showed an upward trend with increasing age (P<0.05), reaching a peak of 1 371.20/105 in the ≥80 years group. The top two causes of chronic respiratory disease deaths were chronic obstructive pulmonary disease and bronchial asthma, with 31 792 cases and 3 254 cases, accounting for 82.40% and 8.43%, respectively. The GM (1,1) grey model prediction results showed that the crude mortality of chronic respiratory diseases in the total population from 2025 to 2029 would be 37.91/105, 36.32/105, 34.80/105, 33.34/105, and 31.95/105, respectively (average relative error=8.76%). Conclusions From 2011 to 2024, the mortality of chronic respiratory diseases in Lianyungang City showed a downward trend. The risk of death from chronic respiratory diseases was higher in males, rural areas, and the elderly. It is predicted that the mortality of chronic respiratory diseases will decrease year by year from 2025 to 2029.

A case of 75-year-old male patient was admitted to the Second Affiliated Hospital of Harbin Medical University on June ,2024 complaining 'repeated cough for half a year', accompanied by night fever, night sweats, fatigue, weight loss. He was initially diagnosed as diffuse large B-cell lymphoma through chest CT and bronchoscopic biopsy, then confirmed as diffuse large B-cell lymphoma with MYD88 genetic aberration with bone marrow inconsistent involvement by PET-CT, bone marrow biopsy, immunohistochemistry(IHC),FISH and other tests. The R-CHOP was given as first-line regimen treatment immediately, but the patient appeared allergyic to Rituximab and Zuberitamab sequencially, therefore we change the plan to CDOP for continued chemotherapy and discharged after remission. In his regular admission, we give G-CHOP regimen for chemotherapy, no adverse reactions were found.

Molecular diagnosis has become an important part in the field of precision medicine. With the continuous advancement of molecular diagnostic technologies, their significance in the field of precision medicine has grown, making molecular detection technologies and solutions increasingly important. There are still certain bottlenecks in the current molecular diagnostic approaches, that is, the level of automation in the detection process is insufficient to meet the growing efficiency needs for medical personnel. Although, molecular diagnostic automation has emerged, the existing automation technologies rely on automated equipment to assist laboratory personnel, which is not considered as full automation. In this study, we conducted an in-depth investigation and proposed two distinct solutions to address the current challenges: (1) point-of-care-testing (POCT)-based molecular diagnostic automation solution; (2) pipeline-based molecular diagnostic automation solution. We hope to provide better strategies to improve clinical laboratory testing capabilities and accuracy, and to guide future development of technology in the molecular diagnostic automation industry.

Objective:To evaluate the effect of cathepsin B(CTSB)/NOD-like receptor pyrin domain containing 3(NLRP3)pathway on the polarization of macrophages induced by LPS.Methods:The well-growing RAW264.7 mouse mononuclear macrophage lines were cultured in vitro and divided into 3 groups(n=6)according to the random number table method:control group(C group),LPS group(L group)and LPS+CA074-me(CTSB inhibitors)group(B group).C group was cultured normally for 24 h,L group was cultured with LPS concentration of 1 μg/ml medium for 24 h.B group was pretreated with CTSB inhibitor CA074-me 30 μmol/L for 1 h before LPS induction,and co-cultured with LPS concentration of 1 μg/ml medium for 24 h.After 24 hours,the morphological changes of the cells were observed by microscope,the concentrations of IL-1β and IL-18 in the supernatant were determined by ELISA.The ex-pressions of cathepsin B precursor(pro-CTSB),mature cathepsin B(mature-CTSB),NLRP3,apoptosis-related speck protein(ASC)and apoptosis-related speck protein-1(caspase-1)were detected by Western blot.The mRNA expression levels of CD32,inducible ni-tric oxide synthase(iNOS),arginase 1(Arg-1)and CD206 were detected by qRT-PCR.The positive expression rates of M1 macro-phage surface marker CD86 and M2 macrophage surface marker CD206 were detected by flow cytometry.Results:Compared with group C,the morphology of cells in groups L and B became larger and pseudopodia appeared.The concentrations of IL-1β and IL-18 in cell supernatant were increased,the expressions of pro-CTSB,mature-CTSB,NLRP3,ASC and caspase-1 were increased,and the expressions of CD32,iNOS mRNA were up-regulated and the positive rates of CD86 and CD206 were increased(P<0.01).Arg-1 and CD206 mRNA in group B were up-regulated(P<0.01).Compared with group L,the pseudopodia of group B were reduced,and the morphology was closer to group C.The concentration of IL-1β and IL-18 in the supernatant,the expression of mature-CTSB,NLRP3,ASC and caspase-1,CD32 and iNOS mRNA and the positive rate of CD86 were down-regulated in group B.The expression of pro-CTSB,Arg-1 and CD206 mRNA and the positive rate of CD206 were increased(P<0.01).Conclusion:Inhibition of CTSB/NLRP3 pathway can reduce the inflammatory response,reduce the LPS-induced polarization of RAW264.7 cells to M1 macrophages,and pro-mote their polarization to M2 macrophages.

Objective The aim of this study was to analyze the incidence and mortality of esophageal cancer and its trend in Lianyungang city from 2008 to 2019.Methods The data of esophageal cancer in all cancer registry areas in Lianyungang city were col-lected and sorted out,and the quality control reached the standards.The incidence,mortality,age-standardized rate of Chinese population(ASRC),age-standardized rate of World population(ASRW),cumulative rate at 0-74 years old,truncation rate of 35-64 years old,and composition ranking were calculated.The Joinpoint4.7.0.0software was used to analyze the average annual percentage change(AAPC)of the age-standardized incidence and mortality of esophageal cancer by the standard population(ASIRC and ASMRC).Results From 2008 to 2019,the incidence of esophageal cancer in Lianyungang city was 25.90/100,000,ASIRC was 17.95/100,000,ASIRW was 17.91/100,000,ranking the third in the incidence spectrum of malignant tumors.The mortality was 20.55/100,000,ASMRC was 13.86/100,000,and ASMRW was 13.71/100,000,ranking the third in the malignant tumor mortality spectrum.The incidence,mortali-ty,ASIRC and ASMRC of esophageal cancer were higher in men than those in women,and higher in rural areas than those in urban are-as.From 2008 to 2019,the change trend of incidence and mortality of esophageal cancer in Lianyungang city was the same,showing a downward trend.The AAPC of the ASIRC was-6.19%(95%CI:-7.08%-5.30%,P<0.001),and the AAPC of the ASMRC was-4.03%(95%CI:-5.81%-2.22%,P<0.001).Among them,the ASIRC and ASMRC of esophageal cancer in urban and rural areas showed a downward trend(P<0.05).Among them,the ASIRC and ASMRC of esophageal cancer in urban women decreased the most,with an average annual decline of-7.99%(95%CI:-10.86%-5.03%,P<0.001)and-9.19%(95%CI:-12.35%-5.93%,P<0.001).Conclusion The incidence and mortality of esophageal cancer in Lianyungang city have shown a downward trend,a rural areas and male populations are the key prevention and control populations for esophageal cancer.

Breast cancer is the leading cause of cancer-related mortality among women worldwide and has drawn extensive research attention.Owing to its molecular heterogeneity,drug resistance,and low therapeutic response,single-modality treatments often fail to achieve satisfactory efficacy or broad applicability.Combination therapy,designed based on the pathophysiological characteristics,related signaling pathways,and biomarkers of breast cancer,has emerged as a promising approach for improving therapeutic outcomes.With the advancement of research on combination strategies,the understanding of their molecular mechanisms—particularly key signaling pathways and biomarkers—has become increasingly important.However,comprehensive reviews addressing these molecular mechanisms and synergistic strategies remain scarce.This article summarizes recent advances in combination therapy for breast cancer,providing a comprehensive review of recent combination therapies for breast cancer and their underlying molecular mechanisms,and focusing on key signaling pathways involved in combination therapy and synergistic strategies,thereby providing theoretical insights and reference for researchers,graduate students,and clinicians engaged in the development of novel combination therapeutic strategies for breast cancer and related malignancies.

Objective To explore the effectiveness of a hospital-to-home transitional health management program for caregivers of children with severe encephalitis,aiming to provide a reference for optimizing transitional care models for these patients.Methods A convenience sampling method was used to select 84 children with severe encephalitis and their caregivers admitted to the neurology department of a tertiary hospital in Zhengzhou between March 2023 and June 2024.According to the admission time,they were divided into an experimental group and a control group,with 42 cases in each group.The experimental group received a hospital-to-home transitional health management program in addition to routine care,while the control group received standard care and discharge instructions.Differences in caregivers' perceived benefits,caregiver burden,disease management ability,and post-intervention outcomes of the children were compared between the 2 groups before and after the intervention.Results All 42 participants in both groups completed the study.After the intervention,the experimental group reported higher perceived benefits of(91.29±9.76)compared to(84.81±12.86)in the control group,lower caregiver burden of(48.55±7.15)compared to(54.71±11.23)in the control group,greater disease management ability of(41.83±4.97)than(37.79±5.23)in the control group,and lower difficulty in disease management of(31.52±7.82)compared to(34.55±3.96)in the control group,with all differences being statistically significant(P＜0.05).No statistically significant difference was found in the prognosis of the children between the 2 groups(P=0.500).Conclusion The hospital-to-home transitional health management program can effectively enhance caregivers'perceived benefits and disease management capabilities,reduce their caregiving burden,and provide scientific evidence for optimizing transitional care for children with severe encephalitis.
