Objective: To explore the association of vegetables and fruits intake with depressive symptoms among multi ethnic first year junior high school students in Yunnan Province, so as to provide data support for preventing and reducing depressive symptoms among first year junior high school students. Methods: From October to December 2022, a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas in Yunnan Province (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County), to investigate with a questionnaire. The Dietary Frequency Questionnaire was used to collect dietary behavior datas, and the Chinese version of Depression Anxiety Stress Scale-21 (DASS-21) was used to assess depressive symptoms. The generalized linear model was used to analyze the association of vegetable and fruit intake with depressive symptoms in students, and stratified analysis was performed according to ethnicity. Results: The detection rate of depressive symptoms among first year junior high school students in Yunnan Province was 29.5%. The detection rates of depressive symptoms in Han and minority first year junior high school students were 26.9% and 31.6%. After controlling for demographic variables such as gender, age, family residence and other confounding factors, the generalized linear model analysis results showed that the intake of leafy vegetables ( β= -0.07 , 95%CI =-0.12 to -0.01), flat fruits ( β=-0.06, 95%CI =-0.12 to -0.00) and hot natured fruits ( β=0.11, 95%CI = 0.04- 0.17) were associated with depressive symptoms in Han first year junior high school students (all P <0.05). The intake of melon and fruit vegetables ( β=-0.06, 95%CI =-0.11 to -0.01) and hot natured fruits ( β=0.06, 95%CI =0.01-0.12) were associated with depressive symptoms in ethnic minority first year junior high school students (both P <0.05). Conclusions The intake of vegetables and fruits among multi ethnic first year junior high school students in Yunnan Province is related to the risk of depressive symptoms. It is suggested to strengthen the consumption guidance and education of vegetables and fruits to prevent depressive symptoms among first year junior high school students.

Objective To systematically review international research on health communication, and to provide valuable insights and reference for China's health communication research and practice. Methods This study included 693 articles published from January 2023 to April 2024 in two authoritative academic journals in the field of health communication, ^“Health Communication^” and the ^“Journal of Health Communication^”. A systematic review was conducted on the themes, theoretical foundations, research methods, and populations of international health communication research. Results The findings in this study revealed that international health communication research topics were diverse, with hotspots including social media, health information behavior, health misinformation, stigmatization, trust, and risk perception. The results showed that 34% of the articles were based on theoretical foundations, and 93.3% employed research methods, focusing on adolescents, parents, women, and other key populations. Conclusion Domestic health communication research can expand its perspective from ^“information transmission^” to ^“social interaction^”, innovate theories and methods from ^“single paradigm" to ^“multi-integration^” and shift focus from a ^“mass perspective^” to ^“targeted care^” for the health of all populations. Domestic health communication practice can delve into the localization of social media health communication practices, the comprehensive management of health misinformation, and the critical application of new technologies.

ObjectiveTo construct and validate a clinical prediction model for inflammatory remission outcomes in rheumatoid arthritis （RA） patients with liver and kidney deficiency syndrome treated with Bushen Zhiwang Decoction （补肾治尪汤， BZD） based on metabolomics. MethodsA prospective cohort study was conducted， enrol-ling 60 RA patients with liver and kidney deficiency syndrome. All patients were treated with BZD and conventional-dose oral conventional synthetic disease-modifying antirheumatic drugs （csDMARDs） for 12 months. Clinical data were collected， and the change in disease activity score in 28 joints （DAS28） after treatment compared with baseline （△DAS28） was used as the primary outcome and grouping criterion. Peripheral blood samples were collected before treatment to analyze plasma metabolites. Differential analysis and least absolute shrinkage and selection operator （LASSO） regression were used to preliminarily screen differential metabolites， followed by machine learning algorithms to further identify a core metabolite combination. Based on the expression levels of the core metabolite combination， a novel metabolite index， namely the metabolomics-based inflammatory remission score （Met-IRS）， was calculated using standar-dized metabolite values， and its clinical applicability was evaluated. A clinical prediction model was constructed by integrating clinical characteristics and Met-IRS， and the model performance was assessed. ResultsAmong the 60 patients， those with △DAS28 ≥ 0.27 were assigned to the high inflammatory remission group， while those with △DAS28 ＜ 0.27 were assigned to the low inflammatory remission group， with 30 cases in each group. Compared to the low inflammatory remission group， the high inflammatory remission group showed a higher frequency of methotrexate use and a lower positive rate of rheumatoid factor （RF） （P＜0.05）. Seven core metabolites were identified as the optimal combination， including mangiferic acid， fatty acid-hydroxy fatty acid ester 40∶6， fatty acid-hydroxy fatty acid ester 18∶0， fatty acid-hydroxy fatty acid ester 36∶1， glucosylceramide， lysophosphatidylcholine 22∶5， and pregnanetriol ketone. The calculated Met-IRS comprehensively reflected the characteristics of differential metabolites and demonstrated clinical applicability. Met-IRS was significantly higher in the high inflammatory remission group than in the low inflammatory remission group， and was positively correlated with high inflammatory remission outcomes （P＜0.05）. Based on the variables Met-IRS， methotrexate use， leflunomide use， and RF positivity， a clinical prediction model for inflammatory remission in RA treatment （Cj-RTRM） was constructed. Model performance evaluation demonstrated that the model had good clinical predictive ability， with an area under the receiver operating characteristic curve （AUC） of 0.880， sensitivity 0.967， specificity 0.700 and Youden's index 0.667. ConclusionThe clinical prediction model Cj-RTRM constructed based on the metabolomics-based inflammatory remission score Met-IRS can effectively predict clinical inflammatory remission outcomes in RA patients treated with BZD and accurately identify the advantageous population for this treatment. This model provides guiding evidence for dynamic inflammation monitoring， targeted management， and identification of populations with advantages in traditional Chinese medicine.

Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronic immune-mediated disease with uncertain causes. Malnutrition in IBD patients, attributed to factors such as inadequate intake, increased consumption, poor absorption, and bacterial overgrowth in the small intestine, poses a prevalence of 23%–50%, elevating the risk of readmission and mortality while diminishing quality of life. Therefore, urgent implementation of personalized dietary interventions is crucial for enhancing adherence and rectifying malnutrition in IBD patients.

Objective To analyze ancient prescriptions for knee osteoarthritis(KOA),and explore their application patterns,for providing clinical reference value.Methods Prescriptions were collected from ancient documents,and a database was created by using Excel 2016 for frequency analysis.Association rules and hidden structures were analyzed by using SPSS Modeler 18.0 and Lantern 5.0.Results A total of 373 prescriptions and 421 herbs were collected,with 3894 times of frequency of medication.Danggui was the most frequently used herb.Herbs primarily tonified deficiencies,relieved exterior symptoms,and expelled wind-dampness,with warm properties and pungent,sweet,or bitter tastes,mainly targeting the spleen and kidney meridians.Thirteen strong association rules were identified,including Chuanxiong+Niuxi-Danggui,and Bixie-Niuxi.Hidden structure analysis revealed 10 variables,leading to 4 clusters and 4 core prescriptions.Common syndromes included wind-damp,wind-cold-damp,wind-damp-heat,and qi-blood deficiency.Conclusion The treatment of KOA in ancient literature focuses on dispelling wind and removing dampness,taking into account both positive deficiency and evil excess,flexible use of tonifying spleen and kidney,clearing dampness-heat,tonifying Qi and blood and other drugs.

[Purpose]To analyze the incidence and mortality of liver cancer in Fusui County of Guangxi Zhuang Autonomous Region in 2019 and the trend of change from 201 1 to 2019.[Meth-ods]Based on the incidence and mortality data of liver cancer in Fusui County from 2011 to 2019,the crude incidence rate,crude mortality rate,age-standardized rate by Chinese standard population(ASIRC/ASMRC),age-standardized rate by world standard population(ASMRW/ASM-RW),disability-adjusted life years(DALY),years of life lost(YLL),years of lived with disability(YLD)were calculated.The Joinpoint linear regression model was used to calculate the average annual percentage change(AAPC)of the ASIRC/ASMRC and DALY rate of liver cancer in Fusui County from 2011 to 2019.[Results]In 2019,there were 345 new cases and 298 deaths of liver cancer in Fusui County,accounting for 28.49％and 35.86％of all new cases and death cases of malignant tumors in Fusui County,respectively.The crude incidence rate,ASIRC and ASIRW were 74.71/105,67.55/105 and 65.63/105,respectively;the crude mortality rate,ASMRC and ASMRW were 64.53/105,58.78/105 and 56.88/105,respectively.In 2019,ASIRC/ASMRC of men were higher than those of women(105.32/105 and 95.67/105 for men;27.26/105 and 19.11/105 for women).The peak incidence and mortality rates were in the 65～69 and 80～84 age groups,re-spectively.The incidence rate of liver cancer in Fusui County declined from 82.50/105 in 2011 to 67.55/105 in 2019,with an AAPC of-3.01％(P=0.024),but the mortality rate did not have sig-nificant changes(AAPC=-1.44％,P=0.224).The rate of DALY decreased from 14.51/105 to 10.36/105,with an AAPC of-2.82％(P=0.050).[Conclusion]The incidence rate and DALY rate of liv-er cancer in Fusui County showed an overall decreasing trend from 2011 to 2019,but still re-mained at a high level.It is necessary to further strengthen the prevention,screening and early treatment of liver cancer in this region,especially for men and the elderly.

This study examines the progress and application of Artificial Intelligence (AI) in the prevention and control of infectious diseases within Chinese healthcare institutions. It analyzes the difficulties and challenges encountered during implementation to promote the intelligent transformation and upgrading of infectious disease prevention and control. The results indicate that AI technology has made progress in areas such as infectious disease surveillance and early warning, risk assessment and emergency response, screening and detection, image-based diagnosis and analysis, and health management. Nevertheless, significant challenges remain, including limited application depth and breadth, issues with data quality and privacy protection, insufficient technological maturity and interpretability, potential legal risks, and a shortage of interdisciplinary professionals. To advance the application of AI technology in infectious disease prevention and control and support the modernization of China′s relevant systems, recommendations include strengthening policy support, establishing data standards and robust privacy protection mechanisms, increasing R&D investment, refining laws and regulations, and enhancing the training of interdisciplinary talent.

This study compared the clinical characteristics of brucellosis,tuberculosis,and their co-infections,to improve dif-ferential diagnosis and disease management.A retrospective analysis was conducted on 41 patients with brucellosis,38 co-infected pa-tients,and 95 patients with tuberculosis admitted to Beijing Chest Hospital,Capital Medical University,between January 2017 and December 2024.Clinical manifestations,laboratory findings,and complications were analyzed statistically.Brucellosis and tuberculo-sis shared clinical similarities,such as presentation with prolonged fever.However,patients with brucellosis tended to exhibit muscle pain,night sweats,and loss of appetite,whereas patients with tuberculosis frequently presented with cough,sputum production,and lymphadenopathy.Co-infected patients had a higher fever incidence,and elevated hs-CRP and ESR levels.Whereas spinal spondyli-tis was more frequent in brucellosis,pulmonary infections and pleural effusion were predominant in tuberculosis.Co-infected patients exhibited characteristics of both diseases,and showed more severe systemic inflammation and prolonged illness.In conclusion,al-though elevated hs-CRP and ESR might aid in differentiation,pathogen detection is crucial for accurate diagnosis.Strengthening screening in patients with persistent fever and systemic inflammation may improve early identification,optimize treatment,and en-hance outcomes.

Objective:To investigate the alterations in voxel-mirrored homotopic connectivity (VMHC) of brain regions, association loop connectivity, and white matter microstructure in patients with white matter hyperintensities (WMH) of presumed vascular origin, and analyze the pathological basis of cognitive impairment in WMH patients.Methods:A prospective study was performed; 75 WMH patients (WMH group) admitted to Jiangsu Shengze Hospital Affiliated to Nanjing Medical University from January 2023 to September 2024 and 67 volunteers without obvious brain diseases (control group) recruited during the same period were enrolled. General data of these participants, and scores of neuropsychological scales such as mini-mental state examination (MMSE), frontal assessment battery (FAB), and trail making test (TMT) were compared between the two groups. Resting-state functional magnetic resonance imaging (rs-fMRI) and diffusion tensor imaging (DTI) data of all participants were collected; rs-fMRI data were then analyzed using VMHC algorithm to calculate and conform the brain regions with significantly different VMHC between the two groups, and these regions were used as seed points to perform functional connectivity with the whole brain; Pearson correlation analyses of VMHC and functional connectivity in these brain regions with scores of neuropsychological scales were performed. DTI data were processed using tract-based spatial statistics (TBSS) method to calculate and conform the brain regions with significantly different diffusion parameters of fiber tracts between the two groups; Pearson correlation analyses of diffusion parameters of the fiber tracts in these brain regions with scores of neuropsychological scales were performed.Results:(1) Comparison of general data and neuropsychological scale scores: proportion of participants with hypertension history was significantly different between the two groups ( P<0.05); scores of TMT-A, TMT-B, and Stroop C scales in the WMH group were significantly higher than those in the control group ( P<0.05). (2) Comparison of VMHC and seed point functional connectivity: compared with that in the control group, the VMHC in bilateral middle occipital gyrus, visual cortex, medial occipitotemporal gyrus, insula, and postcentral gyrus of the WMH group were statistically lower ( P<0.05). Compared with that in the control group, functional connectivity of right visual cortex with right middle temporal gyrus, bilateral precuneus, and right dorsolateral superior frontal gyrus in the WMH group was significantly weakened, and functional connectivity of right postcentral gyrus with right medial occipitotemporal gyrus, left middle temporal gyrus, left visual cortex, and left postcentral gyrus was statistically weakened ( P<0.05). In the WMH group, the VMHC of bilateral insula was negatively correlated with TMT-B score ( r=-0.381, P<0.001), and functional connectivity between right visual cortex and right dorsolateral superior frontal gyrus was negatively correlated with Stroop C score ( r=-0.401, P<0.001). (3) TBSS results: the diffusion parameters of the anterior corona radiata, superior corona radiata, corpus callosum, superior longitudinal fasciculus, and posterior thalamic radiation were statistically significant between the two groups ( P<0.05). In the WMH group, the fractional anisotropy in the genu of the corpus callosum was positively correlated with Stroop C score ( r=0.426, P<0.001), radial diffusivity was negatively correlated with Stroop C score ( r=-0.376, P<0.001), and mean diffusivity of the left anterior corona radiata was negatively correlated with TMT-A score ( r=-0.443, P<0.001). Conclusion:WMH patients have decreased coordination in homotopic brain regions and weakened functional connectivity of association loops, with widely distributed white matter microstructure damages, which may be involved in the neuropathological process of cognitive impairment.
