ObjectiveThis paper aims to investigate the protective effects of the Tanyu Tongzhi Youhua prescription（TYTZP） against myocardial ischemia/reperfusion injury in rats via regulation of the cyclic GMP-AMP synthase （cGAS）/stimulator of interferon genes （STING） signaling pathway. MethodsFifty-six 8-week-old male Sprague-Dawley （SD） rats were randomly divided into sham group， model group， ticagrelor group （32.4 mg·kg^-1）， RU320521 （RU.521cGAS inhibitors） group （5 mL·kg^-1）， groups of TYTZP with low dose （3.6 g·kg^-1）， medium dose （7.2 g·kg^-1）， and high dose （14.4 g·kg^-1）， with eight rats per group. The ticagrelor group and groups of TYTZP with different doses received pre-treatment for seven days according to their respective protocols. The RU.521 group received an intraperitoneal injection one hour before modeling. A rat model of the no-reflow phenomenon in myocardial ischemia/reperfusion injury was established by ligating the left anterior descending coronary artery in situ. Myocardial no-reflow area was determined by thioflavin staining. Histopathological morphology of myocardial tissue was observed via hematoxylin and eosin （HE） staining. Cardiac function was detected by echocardiography. Myocardial microcirculation function change was observed by using real-time myocardial contrast echocardiography. The myocardial enzyme levels in the serum were measured by serum biochemical analysis. The double-stranded DNA （dsDNA） levels were detected by using PicoGreen. The protein expression of cGAS， STING， and nuclear factor-κB （NF-κB） p65 in myocardial tissue was detected by Western blot. The levels of cardiac troponin Ⅰ （cTNⅠ）， cardiac troponin T （cTNT）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in the peripheral blood were measured by enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the sham group， the model group showed a significantly increased myocardial no-reflow area （P<0.01）. Myocardial fiber rupture and disarray and inflammatory cell infiltration were observed by HE staining. The ultrasound results indicated that left ventricular ejection fraction （LVEF） and left ventricular fractional shortening （LVFS） （P<0.01） were significantly decreased. Real-time myocardial contrast echocardiography showed that the peak time of myocardial blood perfusion was significantly prolonged （P<0.01）， and the levels of creatine kinase （CK）， creatine kinase isoenzyme （CK-MB）， lactate dehydrogenase （LDH）， cTNⅠ， cTNT， and dsDNA were significantly elevated （P<0.01）. Western blot results showed that the myocardial protein expressions of cGAS， STING， and NF-κB p65 were upregulated （P<0.01）. ELISA results showed that the inflammatory factors in the serum such as IL-6， IL-1β， and TNF-α were increased （P<0.01）. Compared with the model group， the group of the TYTZP significantly reduced the levels of myocardial enzyme， troponins， and dsDNA （P<0.01， P<0.05）， improved cardiac function and myocardial microcirculation， alleviated histopathological morphology and inflammatory infiltration， inhibited activation of the cGAS/STING pathway， reduced the expression of NF-κB p65 （P<0.01， P<0.05）， and inhibited inflammatory response. ConclusionThe TYTZP mitigates the no-reflow phenomenon in myocardial ischemia/reperfusion injury， and its mechanism is associated with inhibiting the activation of the cGAS/STING pathway and attenuating inflammatory responses.

Atherosclerosis （AS） is a chronic and inflammatory vascular disease. Macrophages are common immune cells and play an important role in the development of AS. In recent years， research has found that the formation of AS plaques is closely related to pathological and physiological processes such as macrophage polarization， energy metabolism， and lipid phagocytosis. This review aims to summarize the mechanism of macrophages in the development of AS， and to explore potential therapeutic methods for delaying AS by regulating macrophages， providing new ideas for the treatment and research of AS.

Purpose To investigate the correlation between tumor budding in penile squamous cell carcinoma(SCC)and its clinicopathological features.Methods Clinical data and pathological slides from 69 cases of penile SCC were collected.Tumor budding was examined microscopically,and statistical analyses were performed to assess the relationship between tumor budding and various clinicopathological features.Results Among the 69 cases of pe-nile SCC,41 cases exhibited low-grade tumor budding and 28 cases displayed high-grade tumor budding.Tumor bud-ding was significantly correlated with tumor size,urethral invasion,invasion of the urethral corpus spongiosum,inva-sion of the penile corpus cavernosum,tumor necrosis,nerve invasion,vascular tumor thrombus,and pathological T stage(all P＜0.05).In contrast,no significant association was found between tumor budding and HPV-related versus non-HPV-related penile SCC(P＞0.05).Log-rank survival analysis indicated that patients with high-grade tumor bud-ding had a significantly lower survival rate compared to those with low-grade tumor budding(P＜0.05).Conclusion Tumor budding is a distinct pathological feature of penile SCC,and high-grade tumor budding is associated with a more aggressive biological behavior.

Objective To systematically analyze the cross-sectoral health policy frameworks and strategic priorities of the World Health Organization(WHO),United Nations Educational,Scientific and Cultural Organization(UNESCO),Euro-pean Union(EU),and China in promoting college students'physical activity,adolescent health and mental health,to explore the ways integrating physical activity-related health policies with the polices of college students health and quality physical education.Methods Based on WHO's health promotion framework and with reference to the"Health in All Policies"(HiAP)ap-proach,a content analysis was conducted on health-related policies of WHO,UNESCO,EU and China.Results In the health sector,the international community established a policy system centered on health promotion and the governance concept of HiAP.WHO's Global Action Plan on Physical Activity 2018-2030 and related strate-gies on mental health identified physical activity as a core measure to promote both physical and mental health.The EU's recommendations on Health-Enhancing Physical Activity provided a scheme for translating global strat-egies into monitorable cross-sectoral regional actions.China's national strategies,such as Healthy China 2030 Planning Outline and Integration of Sports and Education demonstrated strong advantages in policy mobilization and resource allocation,with distinct focuses compared to international frameworks in terms of policy systematic-ity,participatory implementation and evaluation orientation.In the education sector,international policies empha-sized the integration of health promotion and education,evolving from ensuring Physical Education Hours to pro-moting Quality Physical Education and Physical Literacy.Through the frameworks like Kazan Action Plan and Health Promoting Universities represented by Okanagan Charter,campus sports was elevated to a level of serv-ing sustainable development and promoting overall well-being.China's National Fitness Program(2021-2025)and Basic Standards for Physical Education in Higher Education Institutions provided specific implementation plans for such integration.Conclusion For the cross-sectoral issue of college students physical activity and health,the international community has constructed an integrated policy framework based on health promotion,integrating policies on physical activity,adolescent health and mental health,to establish a more comprehensive,systematic and inclusive path.In higher education,the trend of integrating health and education policies is significant;physical activity is no longer re-garded as an isolated issue in physical education,but as a key cross-cutting strategy and policy to address non-communicable diseases,improve mental health,promote the holistic development of youth,and achieve the Sus-tainable Development Goals.China should,on the basis of Integration of Sports and Education,further expand HiAP-based cross-sectoral collaboration in accordance with health promotion principles;policy goals should not only focus on physical fitness standards,but also consider intrinsic interest,enjoyable experience and lifelong habit formation;and actively draw on the holistic systems perspective of Health Promoting Universities to build a supportive campus health promotion ecosystem that facilitates the comprehensive physical and mental develop-ment of every student.

YTHDF2 is a key m6A RNA modification"reader"that plays a crucial role in cell biological processes and tumor development.This review deeply explores the biological role of YTHDF2 and the advances in its application in tumors.The YTHDF2 structures are divided into mRNA procsomes and YTH domains,which recognize and bind m6A modified RNA molecules.It plays a biological role by promoting mRNA degradation,regu-lating cell signaling pathways and metabolism,and can regulate macrophage function and maintain an immunosup-pressive state in the tumor microenvironment.YTHDF2 has the potential to serve as diagnostic markers,therapeu-tic targets and prognostic evaluation biomarkers in different tumors,but currently relevant studies are insufficient in sample size,molecular mechanism and clinical application.In the future,research can be conducted on compre-hensive clinical research,in-depth analysis of molecular mechanisms,and research and development of optimized treatment strategies.

Objective To explore the mechanism of Lidan Huatan Huoxue Decoction improving cognitive impairment caused by obesity based on metabolomics.Methods Twenty-four 6-week-old male SD rats were randomly divided into a normal group fed with regular diet(Con,n=6)and a modeling group fed with high-fat and high-sugar diet(n=18).Rats with a body mass that is 20%higher than the standard body mass of their age-matched peers fed with ordinary diet were considered to have a successful obese model established.The presence of cognitive impairment was assessed by Morris water maze and Barnes maze tests.After the obese-induced cognitive impairment(OICI)model was established,the modeling rats were randomly divided into a model group(Model,n=6),a donepezil group(Donepezil,n=6),and a Lidan Huatan Huoxue Decoction group(LHH,n=6).Drugs were administered to the donepezil and LHH groups by gastric intubation.The donepezil group was administered with a dose of 0.45 mg·(kg·d)-1,while the LHH group was administered with a dose of 25 g·(kg·d)-1.The normal and model groups were given the same volume of normal saline by gastric intubation for 8 weeks.Before the rats were sacrificed,water maze and Barnes maze experiments were conducted to assess cognitive function.After sacrifice,specimens were collected for biochemical and histological examination of liver tissue and brain tissue.Non-targeted metabolomic analysis using liquid chromatography-mass spectrometry(LC-MS)was performed on feces,serum,and brain tissue to analyze changes in differential metabolites in rats.Results Compared with the model group,the intervention of Donepezil and LHH effectively improved the learning and memory ability of OICI rats(P<0.05 or P<0.01),inhibited the overactivation of hippocampal microglia,and increased the number of hippocampal synaptic proteins.LHH improved metabolic-related indicators in OICI rats(P<0.05 or P<0.01).Metabolomic analysis showed significant differences in metabolites in feces,serum,and brain tissue between the model group and the normal group.The main affected pathways in fecal metabolites included steroid biosynthesis,caffeine metabolism,lysosome,vitamin B6 metabolism,phenylalanine,tyrosine,and tryptophan biosynthesis.The main affected pathways in serum metabolites included central carbon metabolism in cancer,pentose phosphate pathway,mineral absorption,protein digestion and absorption,and aminoacyl-tRNA biosynthesis.The main affected pathways in brain tissue metabolites included glycerophospholipid metabolism,β-alanine metabolism,propionic acid metabolism,niacin and nicotinamide metabolism,and caffeine metabolism.After LHH intervention,fecal metabolites showed the most significant changes,mainly involving vitamin B6 metabolism,vitamin digestion and absorption,histidine metabolism,fructose and mannose metabolism,and steroid biosynthesis.Conclusion LHH can improve cognitive impairment in obese rats mainly by regulating fecal metabolites.The main pathways involved include vitamin B6 metabolism,vitamin digestion and absorption,histidine metabolism,fructose and mannose metabolism,and steroid biosynthesis.Among them,vitamin B6 metabolism and vitamin digestion and absorption may be the most important pathways.

Objective:To investigate the epidemic characteristics of human brucellosis and the awareness of brucellosis prevention and control knowledge among occupational populations in Xuzhou City, Jiangsu Province.Methods:The data of brucellosis cases reported from January to December 2023 in the China Disease Prevention and Control Information System's Infectious Disease Surveillance System where the current residence was Xuzhou City, were collected. The epidemiological distribution characteristics across the three dimensions (time, region, and population) were analyzed, and the etiological characteristics of Brucella strains collected from sentinel hospitals in Xuzhou City during the same period were analyzed. Meanwhile, in September 2023, a survey was conducted on the awareness of brucellosis prevention and control knowledge among occupational populations in 7 counties (cities, districts) with a high incidence of brucellosis in Xuzhou City. Binary logistic regression was used to analyze the influencing factors. Results:In 2023, a total of 124 human brucellosis cases were reported in Xuzhou City, with an annual incidence rate of 1.37/100 000. Brucellosis occurred in all months of the year, with a peak incidence from May to August, accounting for 46.77% (58/124). The incidence rate of brucellosis in Feng County, Pei County, Suining County, Xinyi City and Pizhou City (1.86/100 000) was higher than that in Gulou District, Yunlong District, Quanshan District, Jiawang District and Tongshan District (0.71/100 000), with a statistically significant difference (χ 2 = 19.15, P < 0.001). Among 124 cases of brucellosis, 81 cases (65.32%) were males and 43 cases (34.68%) were females. The incidence rate of brucellosis in males (1.78/100 000) was higher than that in females (0.96/100 000), with a statistically significant difference (χ 2 = 11.08, P < 0.001). The 55 - 64 age group reported a relatively higher number of cases (45 cases, 36.29%), with an incidence rate of 3.97/100 000. The main occupation was farmers (85 cases, 68.55%). In 2023, a total of 9 strains of Brucella were collected from the sentinel hospitals in Xuzhou City, all of which were Brucella melitensis, mainly classified as biotype 3 (7/9). In 2023, a total of 984 occupational population with brucellosis were surveyed in Xuzhou City, and the overall awareness rate of brucellosis prevention and control knowledge was 3.25% (32/984). By binary logistic regression analysis, the awareness rates of brucellosis prevention and control knowledge among veterinarians and those with high school or vocational school education, college education or above were relatively high [ OR (95% CI): 21.24 (1.52 - 297.74), 13.32 (3.48 - 50.96), 18.90 (3.68 - 97.13), P < 0.05]. Conclusions:In 2023, the incidence rate of human brucellosis in Xuzhou City is at a relatively high level, with men, middle-aged and elderly people, and farmers as the main population. The awareness rate of brucellosis prevention and control knowledge among occupational population is relatively low, and it is necessary to strengthen publicity, education, and behavioral intervention.
