Objective: To evaluate the effectiveness of school-family-community comprehensive intervention aimed at reducing sugar sweetened beverage(SSB) consumption among primary and secondary school students, so as to provide scientific basis for relevant departments to formulate campus sugar reduction measures for primary and secondary school students. Methods: In October 2023, a multi stage random cluster sampling method was used to select four primary schools (grade 4) and four junior high schools (grade 7) in Nanjing City, and they were randomly divided into the intervention group ( n =1 601) and the control group ( n = 1 433 ) (primary and secondary schools). The intervention group received a one year comprehensive intervention activity with the theme of “drinking less SSBs and enjoying a healthy life” for one consecutive year. The measures included the school conducting health education courses (once a month, 15 minutes each time), environmental support (posting promotional posters, changing them once a month), class bulletin board and interest projects (once a semester); interventions for families included conducting parent lectures (once per semester 30 min each time), new media (once a month) and hand in hand activities (once per semester); community carried out square promotion and create a supportive environment (post promotional posters and replace them once a month). The control group did not receive any intervention measures except regular health education classes. Self administered questionnaires were used to collect knowledge, attitudes, and intake of SSB at the baseline and after the intervention among primary and secondary school students. Results: After the intervention, the proportion of students in the intervention group with an SSB related knowledge awareness rate of 60% or above was 91.4%, which was higher than that of the control group (81.9%) ( χ 2=60.35, P < 0.01 ). The reporting rate of the behavior of choosing to drink beverages when thirsty in the intervention group was 25.4%, which was lower than that of the control group (33.3%); the reporting rates of informing parents about the hazards of sugar sweetened beverages and paying attention to nutrition labels were 62.0% and 78.0% respectively, both of which were higher than those of the control group (52.3%, 65.9%); the reporting rate of having sugar sweetened beverages at home frequently was 43.7% in the intervention group, which was lower than that of the control group (62.3%); the reporting rate of parents restricting the consumption of sugar sweetened beverages was 84.1%, which was higher than that of the control group (78.4%) ( χ 2= 22.66, 29.05, 54.40, 104.84, 16.24, all P <0.05). The reporting rate of students in the intervention group who consumed sugar sweetened beverages more than 4 times per week was 21.5%, which was lower than that of the control group (28.6%), and the difference was statistically significant ( χ 2=20.36, P <0.01). Conclusion The comprehensive intervention of school-family-community can effectively improve primary and secondary school students knowledge and attitudes regarding SSBs and reduce their consumption of these beverages.

ObjectiveTo construct an actor-network for integrating physical activity into rehabilitation services based on the World Health Organization Rehabilitation in Health Service System framework and actor-network theory (ANT). MethodsContent analysis was employed using the six building blocks of health service systems as the theoretical framework. Actors related to rehabilitation services were extracted and categorized into a rehabilitation actor pool, while a physical activity actor pool was formed based on four major physical activity scenarios. Actors from both pools were integrated, deduplicated and classified to form a final list of integrated actors. Using ANT, the construction process of the actor network integrating physical activity into rehabilitation was analyzed through the four stages of translation: problematization, interessment, enrollment and mobilization. ResultsA dynamic integration network was constructed, comprising human actors (patients, rehabilitation professionals, researchers, sports coaches, government departments, medical institutions, community organizations and industry media, etc.) and non-human actors (assistive devices, sports infrastructure, smart equipment, information systems, online exercise guidance systems, laws and regulations, strategic documents, and exercise prescriptions, etc.). The study identified maximizing rehabilitation outcomes as the mandatory passage point and elaborated on the critical role of government departments as focal actors in coordinating various stakeholders. ConclusionThe integration of physical activity into rehabilitation services is a dynamic network constructed by diverse actors through a process of translation. ANT provides an operational theoretical framework for cross-departmental governance of rehabilitation policies in China, promotes the spatial expansion of the rehabilitation field, and drives its transformation toward a networked and ecological system. The government needs to play a leading role in facilitating role reconstruction and synergy among heterogeneous actors in both the sports and rehabilitation sectors through mechanism design, to create a bidirectional empowerment mechanism that fosters mutual progress and ensures the sustainable development of integrated services.

Objective To investigate the causal relationship between immune cells and various molecular subtypes of breast cancer (BC) by using two-sample Mendelian randomization (MR). Methods This study employed a two-sample MR analysis, with 731 immune cell types from the GWAS catalog as the exposure factors and four BC molecular subtypes (HR+/HER2−, HR+/HER2+, HR−/HER2+, and HR−/HER2−) from the BCAC Consortium as the outcome variables. For causal inference, inverse variance weighting (IVW) was employed as the primary analytical method, alongside multiple consistency validation approaches, including MR-Egger, weighted median, weighted mode, simple mode, and Bayesian weighted Mendelian randomization. Reverse MR and sensitivity analyses were employed to effectively evaluate and exclude potential biases and interference from reverse causality. Results Significant causal associations were identified for specific immune cell phenotypes across subtypes. In HR+ BC, the HER2+ subtype was associated with seven immunophenotypes (five protective and two risk increasing), whereas the HER2− subtype was associated with eight immunophenotypes (four protective and four risk increasing). In HR− BC, the HER2+ subtype was associated with five immunophenotypes (one protective and four risk increasing), and the HER2− subtype (triple-negative BC) was associated with seven immunophenotypes (six protective and one risk-increasing). CD28+CD45RA−CD8+ T cells and naive CD8+ T cells have a bidirectional causal relationship with HR+/HER2+ breast cancer, Whereas the expression of CD8 on CD39+CD8+ cells also has a bidirectional relationship with HR+/HER2− breast cancer. Furthermore, CD4−CD8− NKT cells exhibited opposing effect directions in HER2+ versus HER2− subtypes. Conclusion From a genetic perspective, this study confirms the existence of subtype-specific causal associations between immune cell phenotypes and distinct molecular subtypes of BC, revealing heterogeneity in immune regulation.

ObjectiveTo investigate the incidence， glucolipid metabolism characteristics， and associated factors of postoperative overweight/obesity in children and adolescent with craniopharyngioma. MethodsA retrospective study was conducted using follow-up data from 44 patients （aged 0-18 years） diagnosed with craniopharyngioma who underwent surgical treatment and received follow-up care at Sun Yat-sen Memorial Hospital， Sun Yat-sen University， between January 2006 and February 2024. The incidence and glucolipid metabolism characteristics of overweight/obesity were summarized， and potential influencing factors were analyzed. ResultsA total of 44 patients were enrolled. The mean age at surgery was （8.57 ± 4.25） years， and the mean age at last follow-up was （16.02 ± 5.36 ）years. The mean follow-up duration was （7.45 ± 4.64） years （range， 8 months to 17.5 years）. The preoperative incidence of overweight/obesity was 40.91% （predominantly overweight， 27.27%）， which increased to 68.18% postoperatively （predominantly obesity， 50.00%）. Postoperatively， all patients （44/44， 100%） underwent fasting plasma glucose （FPG） testing， among whom 2 （4.55%） had impaired fasting glucose （IFG）. Fasting insulin （FINS） was measured in 20 patients， and insulin resistance was identified in 11 （55.00%）. Oral glucose tolerance testing （OGTT） with insulin release assessment was performed in 12 patients， and all （100%） exhibited abnormal insulin secretion， including 5 （41.67%） with hyperinsulinemia and 3 （25.00%） diagnosed with diabetes mellitus （DM）. All patients （44/44， 100%） underwent lipid profile assessment. The incidence of dyslipidemia was 81.82% （36/44）， including elevated non-high-density lipoprotein cholesterol （29/44， 65.91%）， hypertriglyceridemia （29/44， 65.91%）， low high-density lipoprotein cholesterol （22/44， 50.00%）， and mixed hyperlipidemia （13/44， 29.55%）. Logistic regression analysis indicated that preoperative overweight/obesity and postoperative abnormal glucose metabolism were significant factors associated with postoperative overweight/obesity. Compared with normal-weight patients， those with postoperative overweight/obesity had higher FINS levels （14.22 mU/L vs. 3.57 mU/L）， higher insulin resistance index（HOMA-IR） （2.88 vs. 0.52）， and a higher incidence of abnormal glucose metabolism （77.78% vs. 23.08%）. However， no significant difference was observed in the incidence of dyslipidemia （94.44% vs. 73.08%）. ConclusionsChildren and adolescent with craniopharyngioma exhibit a higher incidence of overweight/obesity than healthy peers preoperatively， which becomes more pronounced after surgery. This is accompanied by a high incidence of glucolipid metabolic disorders， placing these patients at increased risk of metabolic syndrome， which warrants clinical attention and regular metabolic assessment. In patients who develop postoperative obesity， particular attention should be given to the risk of glucose metabolism abnormalities， and further monitoring of glucose homeostasis is recommended.

Diabetic kidney disease （DKD） is one of the common microvascular complications of diabetes mellitus （DM） and a primary cause of chronic kidney disease （CKD） and end-stage renal disease （ESRD）. Inflammation is currently a hot topic in exploring the pathogenesis of DKD. Macrophages， T cells， interleukins， tumor necrosis factor， NOD-like receptor protein 3 （NLRP3） inflammasome， Janus kinase/signal transducer and activator of transcription （JAK/STAT） signaling pathway， and nuclear factor-kappa B （NF-κB）-related signaling pathway all play a role in regulating the inflammation of DKD and accelerating its progression. Astragali Radix， a Chinese herbal medicine， is widely used in the treatment of DKD and possesses strong anti-inflammatory effects. Studies have revealed that active ingredients of Astragali Radix， including polysaccharides， astragaloside Ⅳ， total flavonoids， calycosin， and quercetin， can regulate multiple signaling pathways to ameliorate the microinflammatory state and alleviate kidney damage， thereby slowing down the progression of DKD. This article systematically reviews the factors influencing the inflammation in DKD and analyzes recent research findings and mechanisms concerning active ingredients of Astragali Radix in the management of DKD inflammation， aiming to offer novel insights and directions for the prevention， treatment， and research of DKD.

Objective To explore the potential clinical value of the ratio of glycated albumin to albumin(GA/ALB)in the occurrence of heart failure(HF)among patients with coronary atherosclerotic heart disease(CHD).Methods A total of 337 CHD patients admitted to the Department of Cardiology in Shanxi Provincial People's Hospital from July 2023 to June 2024 were selected in this study.CHD patients were divided into HF group and non-HF group based on whether they progressed to HF.The clinical data and laboratory parame-ters of the two groups were compared.Restricted cubic spline curve was used to analyze the relationship be-tween GA/ALB levels and the risk of HF in CHD patients.Receiver operating characteristic curve was applied to evaluate the diagnostic efficacy of GA/ALB,GA,platelet to lymphocyte ratio(PLR),and monocyte to lym-phocyte ratio(MLR)in CHD patients with the occurrence of HF.Logistic regression was used to explore the relationship between serum GA/ALB levels and the risk of CHD patients occurrence of HF,and to analyze the degree of influence and stability of subgroup variables on results.Results There were statistically significant differences in GA/ALB,GA,PLR,MLR,and other indicators between the HF group and the non-HF group in CHD patients(P＜0.05).A non-linear relationship was observed between GA/ALB levels and the risk of HF in CHD patients.When the value of GA/ALB multiplied by 10 was less than 5.751,the risk of HF in CHD pa-tients increased with the increase of GA/ALB levels(P＜0.001).GA/ALB was an effective predictor for HF occurrence in CHD patients.Multivariable Logistic regression model showed that GA/ALB was an independ-ent risk factor for CHD patients with occurrence of HF.Subgroup analysis also confirmed the stability of GA/ALB in predicting the occurrence of HF in CHD patients.Conclusion GA/ALB is an independent risk factor for the occurrence of HF in CHD patients,and monitoring GA/ALB levels provides predictive value for the oc-currence of HF in these patients.

This study aims to explore different construction methods for animal models of traditional Chinese medicine(TCM)syndromes and their advantages and disadvantages,to propose optimization strategies for existing problems in current construction methods,and to provide reference for constructing animal models of TCM syndromes that both preserve the essence of TCM syndromes and conform to modern scientific research standards.Using"traditional Chinese medicine","syndrome",and"animal model"as key words,articles related to animal models of TCM syndromes from CNKI,Wanfang,and VIP databases are searched and reviewed.Then the theoretical basis,technical characteristics,and existing problems of the main construction methods of current TCM syndrome animal models are systematically sorted out,and corresponding optimization measures are proposed for the existing problems.The construction methods of TCM syndrome animal models include TCM etiology and pathogenesis construction,modern medical etiology and pathology construction,and integration of TCM and Western medicine for diseases and syndromes.The TCM etiology and pathogenesis construction method is guided by a holistic perspective,constructing syndrome models by simulating external factors such as six pathogenic factors and emotional disorders.Although it conforms to TCM theoretical connotation and has simple operation and strong controllability,this method has problems such as low modeling success rate and poor etiology-syndrome fit.The modern medical etiology and pathology construction method is based on microscopic pathological mechanisms,adopting highly controllable technical means such as drug intervention and surgical modeling.Although it has the characteristics of clear objective indicators and excellent reproducibility,this method has defects such as deviation from the essence of TCM"syndrome"and insufficient safety.The integrated TCM-Western medicine disease-syndrome method shows significant complementarity in syndrome essence restoration degree and technical feasibility,achieves systematic integration of TCM basic theories and clinical syndrome differentiation thinking in methodology,and integrates the objective evaluation system of modern medicine,improving the clinical consistency between Western medicine pathological mechanisms and TCM syndrome evolution patterns.However,this method still faces common challenges such as ambiguous syndrome identification standards and distortion of disease progression simulation.The construction of TCM syndrome animal models faces challenges such as poor theoretical adaptability and poor technical standardization,but has irreplaceable value in verifying the efficacy of prescriptions and promoting the internationalization of TCM.In the future,the construction of TCM syndrome animal models should be optimized through measures such as optimizing animal selection,improving the theoretical basis of preparation methods,standardizing the setting of modeling factors,and clarifying the standard for modeling success.

Objective:To explore effect of Astragalus polysaccharides(APS)through TLR4/NF-κB signal pathway on intesti-nal immune inflammation of rats with dampness stagnancy due to spleen deficiency syndrome based on fecal microbiota transplantation.Methods:Rats with dampness stagnancy due to spleen deficiency syndrome were fed with high-fat and low-protein diet and subjected to exhaustive swimming,transplant flora microbiota after intervention of APS.General condition,changes in weight gain,time of weight exhaustion swimming,spleen index and thymus index were tested.Pathological manifestations of duodenal tissue inflammation were observed by HE staining.Serum IL-1β,IL-6 and TNF-α concentrations of rats were determined by ELISA.Protein levels of TLR4,NF-κB p65 and IκBα in colon were determined by Western blot.Results:Compared with model group,general condition rating,changes in weight gain and time of weight exhaustion swimming in APS-FTG group were increased significantly(P<0.01);spleen index and thymus index were increased;pathological manifestations of duodenal inflammation were significantly relieved;serum IL-1β,IL-6 and TNF-α concentrations were decreased significantly(P<0.01),TLR4 and NF-κB p65 levels in colon were decreased significantly(P<0.05 and P<0.01),IκBα level was in colon increased significantly(P<0.01).Conclusion:APS improves intestinal microbiota of rats with dampness stagnancy due to spleen deficiency syndrome and inhibits TLR4/NF-κB pathway activation through intestinal flora,thus improving intestinal immune inflammation status in rats with dampness stagnancy due to spleen deficiency syndrome.

Objective To analyze the focus and shortcomings of provincial-level digitalization policies for Traditional Chinese Medicine(TCM),and to provide references for improving relevant policies.Methods A three-dimensional analytical framework—comprising"digitalization policy coverage-economic level-TCM development level"was constructed to quantitatively analyze provincial TCM digitalization policy documents issued over the past five years.Results A total of 750 policy items were extracted.Among them,digital applications accounted for the largest proportion(58.13%),while digital governance(26.53%)and digital infrastructure(15.33%)were relatively less emphasized.Two-dimensional analysis revealed that 48.4%of provinces had both low economic levels and low digital policy coverage,while 45.2%had both low TCM development levels and low policy coverage.Multiple linear regression result showed a positive association between digitalization policies coverage and TCM development level,with no significant correlation to economic level.Conclusion Most provincial TCM digitalization policies prioritize application while neglecting governance and infrastructure.There is a need to strengthen talent development and standard system construction,The extent of policy coverage is closely related to the level of TCM development,indicating the need to enhance top-level policy design,Provincial policies vary in focus and can be categorized into three types:industry-driven,technology-driven,and demand-driven.
