Objective: To explore the association role of anxiety and depressive symptoms with Internet gaming disorder (IGD) and emotional-behavioral problems among junior high school students, so as to provide references for preventing the occurrence and progression of emotional-behavioral problems in middle school students. Methods: From September to October 2024, a random cluster sampling method was adopted to select 38 069 students from 28 junior high schools in 14 counties (cities and districts) and functional areas of Jining City, Shandong Province. Surveys were conducted by Nine item Internet Gaming Disorder Scale-Short Form, Generalized Anxiety Disorder-7, Patient Health Questionnaire-9, and Strengths and Difficulties Questionnaire. The correlation of emotional and behavioral issues, online game addiction, anxiety and depressive symptoms among junior high school students was analyzed by Speaman correlation analysis. Mediation analysis was used to explore the role of anxiety and depressive symptoms between IGD and emotional-behavioral problems among junior high school students. Results: The detection rates of emotional-behavioral problems, anxiety symptoms, depressive symptoms, and IGD among junior high school students were 19.24 %, 9.48%, 16.69%, and 19.68%, respectively. The scores of emotional-behavioral problems, anxiety symptoms, depressive symptoms and IGD were 10.00 (6.00, 15.00), 3.00 (0.00, 7.00), and 4.00 (1.00, 8.00), 13.00 (10.00, 19.00), respectively. There were positive correlations between each pair of emotional-behavioral problem, IGD, anxiety symptoms, and depressive symptoms scores ( r =0.51-0.81, all P <0.01). Anxiety and depressive symptoms played mediating roles between IGD and emotional-behavioral problems among junior high school students, with mediating effect values of 0.16 (95% CI =0.15-0.17) and 0.12 (95% CI =0.11-0.14), respectively (both P <0.01). Conclusions Anxiety and depressive symptoms mediate the relationship between IGD and emotional-behavioral problems among junior high school students. It is necessary to identify early signs of IGD among junior high school students, strengthen intervention for anxiety and depressive symptoms, to prevent the occurrence and development of emotional and behavioral issues.

Lung cancer remains one of the leading causes of cancer-related morbidity and mortality worldwide, and its treatment continues to face major challenges such as therapeutic resistance and tumor recurrence. Pyroptosis, a newly characterized form of programmed cell death, induces tumor cell death through gasdermin-mediated membrane pore formation and is accompanied by the release of inflammatory mediators, thereby playing complex roles in lung cancer initiation, progression, and modulation of the tumor microenvironment. Active components and herbal formulas derived from traditional Chinese medicine can modulate pyroptosis-related signaling pathways through multi-target mechanisms, showing potential advantages in inducing lung cancer cell death, inhibiting proliferation and migration, and reversing chemoresistance. This review systematically summarizes relevant studies from domestic and international sources, focusing on the molecular mechanisms of pyroptosis, its roles in lung cancer development and tumor microenvironment remodeling, and the current research progress on traditional Chinese medicine-based interventions targeting pyroptosis, with the aim of providing references for the prevention and treatment of lung cancer using traditional Chinese medicine.

Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

ObjectiveTo investigate the improvement effect of Qibai Pingfei capsules on pulmonary vascular remodeling in rats at different stages of chronic obstructive pulmonary disease （COPD） and to analyze its possible mechanism of action. MethodsMale Sprague-Dawley （SD） rats were randomly divided into a normal group， an early COPD model group， an advanced COPD model group， an early-intervention high-dose group， a late-intervention high-dose group， an early-intervention low-dose group， a late-intervention low-dose group， an early-intervention pyrrolidine dithiocarbamate （PDTC） group， and a late-intervention PDTC group， with 15 rats in each group. A rat model of early COPD was constructed by using cigarette smoke combined with airway infusion using lipopolysaccharide（LPS）， and a rat model of advanced COPD was constructed by using airway infusion with LPS， cigarette smoke， and hypoxia. All groups except the normal group were given LPS airway drops on days 1 and 14 of the experiment， smoked for 1 h per day， and administered the drug once a day for 40 weeks from day 15 onward. In the high- and low-dose groups， rats were given 1 g·kg^-1 and 250 mg·kg^-1 Qibai Pingfei capsules， respectively by gavage， and in PDTC groups， rats were given 100 mg·kg^-1 of PDTC by intraperitoneal injection. The advanced COPD model group underwent 6 h of hypoxia per day in weeks 5-6. Lung function and mean pulmonary artery pressure were tested in rats. Morphologic changes in lung tissues were detected by hematoxylin-eosin（HE）staining. Collagen deposition in lung tissues was examined by Masson staining， and the levels of inflammatory factors including interleukin-1β（IL-1β）， interleukin-6（IL-6）， and tumor necrosis factor-α（TNF-α）in lung tissues were detected by enzyme-linked immunosorbent assay （ELISA）. The number of inflammatory cells in the alveolar lavage fluid of rats in each group was detected by Giemsa staining， and the protein expression of Toll-like receptor 4（TLR4）， myeloid differentiation factor 88（MyD88）， nuclear factor-κB（NF-κB）， TNF-α， vascular endothelial-cadherin（VE-cadherin）， α-smooth muscle actin（α-SMA）， and platelet endothelial cell adhesion molecule-1（CD31） was detected by Western blot in the lung tissues of rats. ResultsCompared with the normal group， the model group showed significantly decreased forced expiratory volume in 0.3 s （FEV_0.3）， forced vital capacity （FVC）， and FEV_0.3/FVC ratio related to lung function （P<0.05）， thickening of pulmonary vasculature， increased collagen deposition in the lungs， and enhanced mean pulmonary arterial pressure and expression levels of IL-6， IL-1β， and TNF-α （P<0.05）. Additionally， the model group also exhibited increased numbers of macrophages， lymphocytes， and neutrophils （P<0.05）， significantly higher protein expression of TLR4， MyD88， NF-κB， TNF-α， and α-SMA （P<0.05）， and significantly lower protein expression of VE-cadherin and CD31 （P<0.05）. Lung function was significantly improved in the Qibai Pingfei capsules groups compared with the model group （P<0.05）， with mean pulmonary arterial pressure reduced and pulmonary vascular thickening and collagen deposition in the lungs ameliorated. The Qibai Pingfei capsules groups also showed reduced expression levels of IL-6， IL-1β， and TNF-α （P<0.05） and decreased numbers of macrophages， lymphocytes， and neutrophils （P<0.05）， as well as reduced protein expression of TLR4， MyD88， NF-κB， TNF-α， and α-SMA （P<0.05） and elevated protein expression of VE-cadherin and CD31 （P<0.05） in rat lung tissues. ConclusionQibai Pingfei capsules inhibits inflammatory response and endothelial-to-mesenchymal transition probably by regulating the TLR4/NF-κB signaling pathway， thus improving pulmonary vascular remodeling in COPD model rats and showing therapeutic effects in the early stage of COPD.

Objective:To analyze the distribution characteristics of sports facilities in China using geographic information system (ArcGIS) and to investigate their association with mortality risk among residents.Methods:This prospective cohort study included 97 912 community residents from the Chinese Family Database (CFD) between 2013 and 2017. After excluding participants lost to follow-up and those with incomplete data, 53 937 individuals were retained for the analysis. The distribution characteristics of sports facilities in China was mapped using ArcGIS, and the death events were recorded via structured interviews and questionnaires. The Poisson regression was used to assess the association between the distribution characteristics of sports facilities near participants′ residences and their mortality risk.Results:In 2013, a total of 79 714 sports facilities were identified across 262 districts (counties) in China, with large-scale sports facilities accounting for the highest proportion (87.09%). The median number of sports facilities within the residential buffer zone was 17 (4, 30), and the median distance from the residence to the nearest sports facility was 453.2 (341.5, 1 863.5) m. Among the 53 937 community residents analyzed in this study, there were 27 761 males and 26 176 females, 1 326 deaths (2.5%) occurred during the follow-up. Poisson regression revealed that a higher number of sports facilities in the buffer zone (≥21 vs 0-2) was associated with lower mortality risk ( RR=0.74, 95% CI: 0.64-0.85; P0.05). Subgroup analyses showed that being≥60 years old ( RR=0.82, 95% CI: 0.70-0.95), males ( RR=0.78, 95% CI: 0.64-0.95), females ( RR=0.79, 95% CI: 0.64-0.97), having a junior high school education or less ( RR=0.84, 95% CI: 0.71-0.99), and having a urban residence ( RR=0.77, 95% CI: 0.66-0.90) were all negatively associated with residents′ mortality risk (all P0.05). After adjusting for age, greater distance to the nearest sports facility ( RR=1.41, 95% CI: 1.08-1.83) and failing to meet the"10-minute fitness circle"criterion ( RR=1.25, 95% CI: 1.02-1.53) were associated with higher mortality risk among males (both P0.05). After adjusting for age and gender, urban residents with a greater distance to the nearest sports facility ( RR=1.29, 95% CI: 1.04-1.60) or not meeting the 10-minute fitness circle ( RR=1.18, 95% CI: 1.00-1.38) showed a significantly higher mortality risk (both P0.05). Conclusions:The ArcGIS analysis revealed that the distribution of sports facilities in China is characterized by a high proportion of large-scale facilities. Lower facility density within residential buffer zone and greater distance to the nearest facility increase mortality risk among adults.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To assess the effectiveness of the evaluation of military physical function(EMPF)system in predicting the occurrence of military training injuries among new recruits to provide scientific guidance and methodological choice for military training.Methods A total of 527 new recruits from 5 grassroots units from July 2016 to February 2018 were selected for the study.The recruits underwent EMPF testing,and their military training injuries were monitored over a 2-year follow-up period.Those who sustained injuries during training were divided into injury group(n=163),while the remaining recruits were placed in healthy group(n=364).The predictive ability of the total EMPF score for training injuries was assessed using the receiver operating characteristic curve(ROC),and the correlation between the total EMPF score,individual test scores,and military training injuries were analyzed using binary logistic regression.Results The total EMPF score of new recruits in injury group(19.52±1.97)was significantly lower than that of healthy group(24.31±1.54)(P<0.001),which also demonstrated a high diagnostic value in predicting the risk of military training injuries,with an area under the curve(AUC)of ROC of 0.971(P<0.001).A cut-off value of 22 scores was found to have the highest accuracy in predicting future training injuries,with an odds ratio(OR)of 25.63,sensitivity of 0.939,specificity of 0.879,positive likelihood ratio of 7.76,and a post-test probability of 0.67.Binary logistic regression analysis revealed that 6 EMPF tests,including holding the ball over and leaning back,bending forward and touching the ground with the ball,lunge squat and twist,swallow balance with holding the ball afterward,vertical jump,and respiratory pattern assessment,were negatively associated with the risk of military training injuries(P<0.0001).Conclusion The EMPF system can effectively predict the risk of military training injuries,with military personnel whose total EMPF score is less than 22 being at higher risk of sustaining such injuries.

To investigate the phenotype and genomic characterization of a mucoid-type Salmonella Saintpaul ST50 isolate from a urinary tract infection patient,promoting clinical diagnosis and treatment for urinary tract infections caused by Salmo-nella spp.Culture-based quantitative counts of midstream urine sample from the patient were conducted,and further biochemi-cal identification,mass spectrometry detection,serum agglutination test and antimicrobial susceptibility test(AST)were con-ducted on Salmonella isolate(2024JD5).Whole-genome sequencing(WGS)was performed on isolate 2024JD5 to predict sero-type,multilocus sequence type(MLST),resistance genes,and virulence genes.Two smooth-type of Salmonella Saintpaul ST50 were selected as comparative genomic reference strains from the Chinese local Salmonella genome database.The literature reviews of global Salmonella serotype of urinary tract infection were summarized.Specific serum agglutination confir-mation of isolate 2024JD5 failed due to characterization of the mucus type.The strain 2024JD5 was predicted as Salmonella Saintpaul(4,5,12:e,h:1,2)ST50 using WGS,and was resistant to ciprofloxacin,nalidixic acid,chloramphenicol and tetracy-cline with carrying aminoglycoside resistance genes aac(6')-Ⅰaa and aph(3)-Ⅱa,chloramphenicol resistance gene floR,tetra-cycline resistance gene tet,quinolone resistance gene qnrS1,and S83Y substitution in the gyrA gene was found in the quinolo-ne resistance determination region(QRDR).In addition,the strain 2024JD4 carried six types of non-plasmid-based mobile ge-netic elements and 144 virulence genes,including 71 secretion transporter genes and 58 fimbriae adhesion genes,respectively.Four types of fimbriae regulatory genes(csgB,csgC,fimW,fimY)were absent in comparison with smooth-type Salmonella Saintpaul.The literature reviews showed Salmonella Saintpaul was currently a rare Salmonella serotype in cases of urinary tract infections worldwide.Salmonella Saintpaul ST50 with mucoid-type is the pathogen of urinary tract infection with multi-drug resistant phenotypic and genotypic characteristics,and the high mucoid expression may be related to the compensatory mechanism of fimbriae regulatory genes absence in urinary tract colonization and adaptation.WGS combined with the Chinese local Salmonella genome database can effectively solve the diagnosis and biosafety assessments of rare Salmonella phenotypes.

Objective To investigate the role of Insulin like growth factor 2 mRNA binding protein 1(IGF2BP1)and long non-coding RNA LINC00160(LINC00160)in gastric cancer,and its potential mechanism of regulating the proliferation and invasion of gastric cancer cells.Methods Quantitative real time polymerase chain reaction(qRT-PCR)was used to detect the expression level of LINC00160 in gastric cancer tissues and cells.Bioinformatics prediction,RNA-binding protein immunoprecipitation(RIP)and methylated RNA immunoprecipitation(MeRIP)were used to verify the binding effect of LINC00160 and IGF2BP1.The correlation between the expression of LINC00160 and IGF2BP1 in gastric cancer tissues was analyzed by Pearson assay.CCK-8 assay and Transwell assay were used to detect cell proliferation and invasion.The changes of aerobic glycolysis index[glucose intake,lactate production,and Adenosine-triphosphate(ATP),extracellular acidification rate(ECAR)and oxygen consumption rate(OCR)]were detected and analyzed.Results Compared with normal tissues,the expression of LINC00160 in gastric cancer tissues(5.13±0.62 vs 1.02±0.03)was significantly up-regulated,and the difference was statistically significant(t=-36.266,P<0.001).The expression level of LINC00160 in gastric cancer cells was higher than that of human normal gastric epithelial cell line GES-1,and the difference was statistically significant(F=24.595,P<0.001).Compared with the control group,silenting LINC00160 significantly inhibited the proliferation(0.42±0.03 vs 1.03±0.04)and invasion(22.13%±1.97%vs 42.15%±2.67%)of AGS cells,decreased glucose uptake(2.11±0.26mmol/L vs 4.22±0.37mmol/L)and lactate production(6.84±1.25mmol/L vs 11.68±1.55mmol/L),decreased ECAR,and increased ATP(3.34±0.29mmol/L vs 1.87±0.24mmol/L)levels and OCR,and the differences were statistically significant(t=4.188～24.423,all P<0.01).The expression of IGF2BP1 protein in gastric cancer tissues(4.07±0.36)was significantly higher than that in adjacent tissues(1.01±0.03),and the difference was statistically significant(t=-46.396,P<0.01),and was positively correlated with the expression of LINC00160(r2=0.774 5,P<0.01).Mechanistic studies revealed that IGF2BP1 upregulated LINC00160 expression by binding m6A modified LINC00160 to promote its stability.Silencing IGF2BP1 significantly inhibited the expression of LINC00160 and the proliferation,invasion and aerobic glycolysis of gastric cancer cells,and the differences were statistically significant(t=4.386～11.989,all P<0.01).Overexpression of LINC00160 reversed the effect of IGF2BP1 silencing on AGS cells.Conclusion LINC00160 is significantly up-regulated in gastric cancer,and IGF2BP1 may stably regulate the expression of LINC00160 through m6A modification,promote the aerobic glycolysis of tumor cells,and participate in the occurrence and development of gastric cancer.

Foodborne illnesses caused by Salmonella pose significant threats to worldwide public health safety.In this study,a rapid method for screening viable Salmonella in oyster sauce and milk was developed by utilizing an electronic microbial growth analyzer(EMGA).Target food samples were diluted 10-fold with RVS broth and loaded into test tubes.Test tubes were positioned in the EMGA to determine the bacterial growth curves and the time required to reach the maximum growth rate(Tmgr).Using Salmonella typhimurium(S.typhimurium)asan model species,there was linear relationship between the logarithmic value of viable bacterial concentration(lgC)and Tmgr over the range of 5×101-5×106 CFU/mL,with a detection limit of 10 CFU/mL.For oyster sauce,the regression equation was Tmgr(min)=-80.775lg[C/(CFU/mL)]+754.96(R2=0.9907),and the recovery rates of S.typhimurium ranged from 95.2%to 119.8%,with relative standard deviations(RSD)ranging from 3.5%to 16.3%.For milk,the regression equation was Tmgr(min)=-71.922 lg[C/(CFU/mL)]+618.65(R2=0.9985),with recovery rates ranging from 98.4%to 110.6%and RSD ranging from 6.4%to 12.8%.The EMGA method required only one portable instrument,and involving only three manual steps,i.e.,dilution,transfer,and insertion.When S.typhimurium contamination reached 106 CFU/mL,the total time consumption,from the unwrapping of samples to the readout of bacterial concentration,was no more than 7 h.When applied to detection of actual oyster sauce and milk samples,the new method demonstrated strong consistency with plate counting results in positive detection rates.This method was superior to the plate counting method,which was generally considered as a gold standard,in terms of accuracy,precision,simplicity and efficiency,representing a promising alternative for the on-site screening and quantification of viable Salmonella in oyster sauce and milk products.
