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.

Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Background:Ribosomal protein L22-like 1(RPL22L1)exerts regulatory effects on various malignant tumors such as lung cancer,prostate cancer,and cervical cancer.However,its role in colorectal cancer(CRC)remains unclear.Aims:To investigate the expression of RPL22L1 in CRC and its role in patients' prognosis and glucose metabolism of tumor cells.Methods:A total of 142 newly diagnosed CRC patients admitted to the Taizhou First People's Hospital from February 2022 to June 2024 were enrolled.The expression levels of RPL22L1 mRNA and protein were detected by quantitative real-time PCR and immunohistochemistry,respectively.The correlation between RPL22L1 expression and clinicopathological characteristics was analyzed.Kaplan-Meier survival analysis was used to evaluate the impact of RPL22L1 expression on the prognosis of CRC patients.RPL22L1 siRNA was transfected into SW480 cells to establish a low-expression cell model.Cell proliferation was assessed by CCK-8 assay,cell migration by Transwell chamber assay,and apoptosis by flow cytometry.Gene set enrichment analysis(GSEA)was performed to evaluate the effect of RPL22L1 on glucose metabolism of tumor cells.Results:The expression levels of RPL22L1 mRNA and protein were significantly higher in CRC tissues than in adjacent normal tissues(all P<0.05).The expression level of RPL22L1 mRNA was correlated with the TNM stage and carcinoembryonic antigen level of CRC(all P<0.05).Kaplan-Meier analysis showed that the cumulative survival rate of high RPL22L1 mRNA expression group was significantly lower than that of low-expression group(P=0.027).The expression level of RPL22L1 mRNA was significantly higher in SW480 cells than in normal intestinal epithelial cells(P<0.001).After inhibiting RPL22L1 expression,the proliferation and migration capacities of SW480 cells were significantly decreased(all P<0.05),the apoptosis rate was significantly increased(P=0.005),and the lactate level and relative glucose uptake level were significantly reduced(all P<0.05).GSEA indicated that RPL22L1 gene was associated with glycolysis/gluconeo-genesis(P=0.02).Conclusions:RPL22L1 is highly expressed in CRC and is associated with poor prognosis of patients,suggesting its potential as a molecular target for CRC therapy.Furthermore,RPL22L1 may promote the tumorigenesis and progression of CRC by modulating glucose metabolism.

Objective:To explore the feasibility of the new auxiliary analysis software in chromosomal aberration analysis of radiation workers during occupational health examinations.Methods:Health examination data of 2 469 radiation workers in Henan province were collected. Manual analysis of chromosomal aberrations in peripheral blood lymphocytes was conducted using the new auxiliary software and the Ikaros software. Then, the chromosomal aberrations detected using both software tools were compared.Results:The new auxiliary software yielded a lower chromosomal aberration rate among radiation workers compared with the Ikaros software [(0.314 ± 0.014)% vs. (0.391 ± 0.022)%, χ2 = 9.24, P = 0.002]. Notably, the new auxiliary software yielded a significantly lower rate of acentric fragments (ace) [(0.136 ± 0.009)% vs. (0.209 ± 0.020)%, χ2= 17.76, P < 0.001]. However, no statistically significant differences were observed between the result of the two software tools in the rates of dicentrics plus rings (dic + r) and translocations ( P > 0.05). According to the GBZ/T 248-2014 standard, the differences in abnormality rates of chromosomal aberrations between the two groups had no statistically significance ( P > 0.05), with both groups showing an abnormality rate of 0 for ace. Furthermore, the new auxiliary software could double the detection efficiency. Among pre-service radiation workers of various occupations, the differences in the chromosomal aberrations detected using the two software tools exhibited statistical significance ( χ2 = 10.26, P = 0.001). In contrast, the differences in the chromosomal aberrations among in-service and post-service radiation workers had no statistically different significance ( P>0.05). The Poisson regression analysis result demonstrated that the rate of chromosomal aberrations excluding ace was affected by age ( z = 2.73, P = 0.006), while gender, analysis method, service status, and occupation had no impact. Conclusions:The two software tools yielded largely consistent result in detecting chromosomal aberrations induced by exposure to ionizing radiation. Notably, the new auxiliary software can significantly improve detection efficiency, indicating the feasibility of applying it to chromosomal aberration analysis among radiation workers.

Background and Aims:Long noncoding RNA(lncRNA)nuclear-enriched abundant transcript 1(NEAT1)is an oncogenic lncRNA that promotes the progression of various cancers through the competing endogenous RNA(ceRNA)mechanism.Using the TargetScan database,we previously identified binding sites between NEAT1 and microRNA-124-3p(miR-124-3p),as well as between miR-124-3p and catenin beta-1(CTNNB1).Therefore,this study was conducted to investigate the expression of NEAT1,miR-124-3p,and CTNNB1 in pancreatic cancer and their interactions affecting pancreatic cancer cell functions.Methods:A dual-luciferase reporter assay was used to validate the relationships among NEAT1,miR-124-3p,and CTNNB1.The expression levels of NEAT1 and miR-124-3p,as well as CTNNB1 protein expression,were detected in pancreatic cancer tissues and adjacent normal tissues,as well as in pancreatic cancer PANC-1 cells and normal pancreatic epithelial H6C7 cells.PANC-1 cells were transfected with NEAT1 siRNA alone or co-transfected with a miR-124-3p inhibitor.After transfection,changes in PANC-1 cell biological functions,epithelial-mesenchymal transition related protein expression,and tumor growth ability in mice were assessed.Results:The dual-luciferase reporter assay confirmed the targeting relationships between NEAT1 and miR-124-3p,as well as between miR-124-3p and CTNNB1.NEAT1 and CTNNB1 expression levels were significantly upregulated,while miR-124-3p expression was downregulated in pancreatic cancer tissues(vs.adjacent tissues)and in PANC-1 cells(vs.H6C7 cells)(all P<0.05).NEAT1 siRNA transfection led to decreased NEAT1 and CTNNB1 expression and increased miR-124-3p expression in PANC-1 cells.However,co-transfection with a miR-124-3p inhibitor suppressed the expression changes in miR-124-3p and CTNNB1(all P<0.05).NEAT1 siRNA transfection significantly reduced PANC-1 cell proliferation,migration,and invasion,while promoting apoptosis.Additionally,E-cadherin protein expression was upregulated,whereas N-cadherin and vimentin protein expression were downregulated.Tumor growth in mice was also significantly inhibited(all P<0.05).These changes were attenuated upon co-transfection with the miR-124-3p inhibitor(all P<0.05).Conclusion:NEAT1 may act as a ceRNA by competitively binding to miR-124-3p,thereby attenuating miR-124-3p-mediated inhibition of CTNNB1.This leads to CTNNB1 upregulation,ultimately promoting the malignant biological behavior of pancreatic cancer cells.
