Objective: To understand the changing trends and related factors of knowledge, attitude and practice (KAP) regarding the three major infectious diseases (acquired immunodeficiency syndrome, tuberculosis, hepatitis B) among freshmen in Jiangsu from 2019 to 2022, so as to provide a reference basis for the health education of infectious diseases in schools. Methods: From 2019 to 2022, a total of 33 944 freshmen from 20 universities in Jiangsu Province were randomly selected for four consecutive years to investigate their KAP levels online through self designed questionnaires on three major infectious diseases. The multiple linear regression model was used to analyze the changing trends of students KAP levels of the three major infectious diseases, and to explore the influencing factors of KAP. Results: From 2019 to 2022, the knowledge scores(18.0±3.1,18.4±3.2,18.7±3.2,18.8±3.2), related to the three major infectious diseases showed an upward trend ( F=436.50, P <0.01), and the positive attitude reporting rates were 81.77%, 81.46%, 82.68% and 81.74%, respectively. The reporting rates of positive practice were 80.11%, 79.25%, 79.08 % and 79.04%, respectively. Multiple linear regression showed that school type, parental education level, mother s occupation, average income per person in family and living arrangements during high school all had an impact on the knowledge ( β = -1.510 -0.559), attitudes ( β =-0.043-0.065) and practice ( β =-0.028-0.027) of the three major infectious diseases ( P < 0.05 ). The family residence areas only affected the reporting rate of positive attitude scores ( β =0.002-0.065), and whether only children or not affected the reporting rate of positive practice scores ( β =0.009)( P <0.05). The knowledge score showed an upward trend ( β= 0.297, P <0.01), the positive attitude reporting rate showed no statistically significant change ( β=0.001, P =0.22), and the positive practice reporting rate showed a downward trend ( β=-0.005, P <0.01). Conclusions Freshman in Jiangsu Province from 2019 to 2022 have shown a separation in KAP scores regarding the three major infectious diseases. Targeted measures should be taken to improve their health practice level.

OBJECTIVE To analyze the quantity transfer rule in the processing of Astragalus membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. METHODS Three batches of A. membranaceus decoction pieces processed through moistening-soaking and steaming-soaking followed by cutting were prepared. The HPLC overlapping fingerprints of A. membranaceus and its decoction pieces were established through the Similarity Evaluation System of Chromatographic Fingerprints of TCM （2012 edition）. Combined with the previous qualitative analysis results， the common peaks were identified， the changes of common peak area were analyzed， and the principal component analysis was carried out. The contents of calycosin-7-glucoside， astragaloside Ⅰ and astragaloside Ⅳ in A. membranaceus and its decoction pieces were determined by HPLC， and the content differences of each component in different samples were compared. RESULTS The results of fingerprint analysis showed that 17 common peaks were identified. After steaming-soaking and moistening-soaking of A. membranaceus， the proportion of common peak area in the decoction pieces changed compared with the original medicine （for example， in A. membranaceus steaming-soaking decoction pieces， the proportion of peak area of malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ decreased， while the proportion of peak area of calycosin-7-glucoside increased）. The results of principal component analysis showed that A. membranaceus， and its decoction pieces after moistening-soaking and steaming-soaking followed by cutting were all clustered into one category respectively. The results of content determination showed that， compared with A. membranaceus， the average content of calycosin-7-glucoside in A. membranaceus moistening-soaking decoction pieces was significantly reduced （P＜0.05）； the average contents of calycosin-7-glucoside and astragaloside Ⅳ in A. membranaceus steaming- soaking decoction pieces were significantly increased （P＜0.05）； there was no significant difference in the average content of astragaloside Ⅳ in A. membranaceus moistening-soaking decoction pieces and astragaloside Ⅰ in the two decoction pieces （P＞ 0.05）. CONCLUSIONS There are differences in the quantity transfer rules of A. membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. Steaming-soaking followed by cutting may make the transformation of unstable components （such as malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ） more complete.

Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

BACKGROUND: Lung adenocarcinoma (LUAD) remains one of the leading causes of cancer morbidity and mortality worldwide, and its initiation and progression are closely associated with the tumor immune microenvironment. Increasing evidence suggests that environmental exposure is a critical factor influencing lung cancer development. Among these factors, fine particulate matter (PM2.5), a major component of air pollution, has been strongly linked to elevated lung cancer risk and unfavorable prognosis. However, the underlying immunoregulatory mechanisms by which PM2.5 drives LUAD progression remain poorly understood. Tumor-associated macrophages (TAMs), especially those polarized toward the M2 phenotype, are key components of the tumor microenvironment and play crucial roles in tumor growth, angiogenesis, and immune evasion. This study aims to investigate the effects of PM2.5 exposure on TAMs and to identify the key pro-tumorigenic factors mediating this process. METHODS: A mouse orthotopic lung cancer model under PM2.5 exposure was established to assess lung tumor growth and macrophage phenotypic alterations using in vivo imaging and flow cytometry. A subcutaneous tumor model involving co-inoculated macrophages and tumor cells was used to further verify the effects of PM2.5 on the function of TAMs and tumor malignancy. Combining in vitro experiments, flow cytometry, Western blot, reverse transcription quantitative polymerase chain reaction (RT-qPCR), cell counting kit-8 (CCK-8) assay, colony formation assay, and wound healing assay were employed to evaluate the regulatory effects of PM2.5 on the polarization of bone marrow-derived macrophages (BMDMs) as well as tumor cell proliferation, migration, and colony-forming ability. Transcriptome sequencing integrated with TISIDB (Tumor-immune System Interactions Database) and GEPIA (Gene Expression Profiling Interactive Analysis) databases was performed to identify key cytokines for further functional validation. RESULTS: In the mouse orthotopic lung cancer model, PM2.5 exposure significantly promoted tumor growth and increased the proportion of M2-type TAMs (P<0.05). Subcutaneous co-inoculation with PM2.5-treated BMDMs markedly enhanced tumor proliferation and elevated the intratumoral M2-type TAMs. PM2.5-pretreated BMDMs exhibited an immunosuppressive programmed cell death ligand 1 (PD-L1)+/arginase 1 (Arg1)+ phenotype, and their conditioned media significantly promoted proliferation, migration, and colony formation of Lewis lung carcinoma cells (LLC) and B16 melanoma cells (B16) (P<0.05). Transcriptome analysis revealed that PM2.5 substantially altered macrophage gene expression, with IL-1α identified as a key upregulated secreted cytokine enriched in immunosuppressive related signaling pathways. Clinical database analyses further indicated that IL-1α expression was positively correlated with macrophage and regulatory T cells (Treg) infiltration in the LUAD immune microenvironment, and that high IL-1α expression was associated with worse overall survival in LUAD patients (HR=1.5, P=0.0053). Western blot, RT-qPCR, and immunofluorescence confirmed that PM2.5 exposure significantly upregulated IL-1α expression and secretion in TAMs. CONCLUSIONS PM2.5 exposure facilitates LUAD progression by inducing an immunosuppressive phenotype in macrophages and enhancing the malignant behaviors of tumor cells. Mechanistically, IL-1α may serve as a key pro-tumorigenic cytokine secreted by macrophages under PM2.5 exposure. This study provides new insights into the pathogenesis of PM2.5-associated LUAD and suggests that IL-1α could serve as a potential therapeutic target.

The seat of human intelligence is the human cerebral cortex, which is responsible for our exceptional cognitive abilities. Identifying principles that lead to the development of the large-sized human cerebral cortex will shed light on what makes the human brain and species so special. The remarkable increase in the number of human cortical pyramidal neurons and the size of the human cerebral cortex is mainly because human cortical radial glial cells, primary neural stem cells in the cortex, generate cortical pyramidal neurons for more than 130 days, whereas the same process takes only about 7 days in mice. The molecular mechanisms underlying this difference are largely unknown. Here, we found that bone morphogenic protein 7 (BMP7) is expressed by increasing the number of cortical radial glial cells during mammalian evolution (mouse, ferret, monkey, and human). BMP7 expression in cortical radial glial cells promotes neurogenesis, inhibits gliogenesis, and thereby increases the length of the neurogenic period, whereas Sonic Hedgehog (SHH) signaling promotes cortical gliogenesis. We demonstrate that BMP7 signaling and SHH signaling mutually inhibit each other through regulation of GLI3 repressor formation. We propose that BMP7 drives the evolutionary expansion of the mammalian cortex by increasing the length of the neurogenic period.

Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost

Objective: To understand the prevalence of school bullying and the comorbidity of anxiety and depressive symptoms among middle school students and their association, so as to provide a basis for developing related intervention strategies. Methods: From September to December 2023, a multistage random cluster sampling was employed to select 107 851 middle school students across 104 counties in Anhui Province. The Center for Epidemiological Studies Depression Scale (CES-D) and the Generalized Anxiety Disorder-7 (GAD-7) Scale were used to assess depressive and anxiety symptoms. Logistic regression analysis was utilized to examine the correlations between experiences of school bullying and the comorbidity of anxiety and depressive symptoms. Results: The findings revealed that 2.80% of middle school students had experienced school bullying in the past 30 days. Additionally, 27.03% exhibited potential symptoms of depression, 8.94% showed signs of anxiety symptom, and the comorbidity rate of anxiety and depressive symptoms was 8.04%. Logistic regression analysis showed that statistically significant correlations were identified between experiences of school bullying and increased risks of depressive symptoms (OR=6.42, 95%CI=5.93-6.94, P<0.01), anxiety symptoms (OR=5.94, 95%CI=5.47-6.44, P<0.01), and their comorbidity (OR=6.38, 95%CI=5.88-6.93, P<0.01). Compared with those who did not suffer from school bullying, junior high school students, ordinary senior high school students, vocational senior high school students, boys and girls who suffered from school bullying all had increased risks of comorbidity of anxiety and depressive symptoms (OR=7.25, 5.55, 4.80, 6.42, 6.27, P＜0.01). Conclusions The study underscores the significant impact of school bullying on increasing the risk of comorbidity of anxiety and depressive symptoms among middle school students. It is important to pay attention to the psychological health of bullied students and implement timely psychological intervention measures.

Objective: To understand the trends and associated factors of tuberculosis knowledge and behavior among freshmen from Jiangsu Province, 2019 to 2022, so as to provide theoretical support for the popularization of tuberculosis knowledge and the prevention and control of tuberculosis in universities. Methods: From 2019 to 2022, a total of 33 944 freshmen from 20 universities in Jiangsu Province were selected by stratified random sampling, and tuberculosis knowledge and behavior were surveyed online using a selfdesigned questionnaire. Oneway variance trend test and multiple linear regression analysis were used to analyze the trend of knowledge and behavior levels, and a multiple linear regression model was used to analyze the influencing factors. Results: The overall awareness rate of tuberculosis among freshmen from Jiangsu Province was 90.6%, and the overall awareness rates from 2019 to 2022 were 88.4%, 90.4%, 91.7%, and 91.8%, respectively. The overall behavioral accuracy rate was 92.3%, with the annual rates from 2019 to 2022 being 91.8%, 92.3%, 92.7%, and 92.4%, respectively. Both the awareness rate and accuracy behavior rate increased annually (F=216.67, 11.75, P<0.01). The multiple linear regression analysis showed that school type, ethnicity, fathers educational level, mothers educational level, mothers occupation, family per capita monthly income, and living arrangement in high school affected both personal knowledge awareness rate and personal behavioral accuracy rate (β=-0.047-0.035, P<0.01), while region, gender, family residence, and being an only child only affected behavioral accuracy rate (β=-0.003-0.032, P<0.05). Conclusions The tuberculosis knowledge and behavior levels of freshmen from Jiangsu Province have been increasing by year. Targeted health education should be carried out based on the relevant influencing factors to further enhance the tuberculosis prevention and control literacy.

Background Prolonged grief disorder(PGD)has serious impact on the quality of patients' work and life.Previous relevant studies have explored the intervention effect of cognitive behavioral therapy(CBT)on PGD,but their conclusions remain controversial due to differences in frequency,time and content of intervention.Objective To explore the intervention effects of CBT on the PGD through Meta-analysis,so as to provide references for clinical treatment.Methods On October 22,2022,the database of VIP,China Biomedical Literature Database,Wanfang,CNKI,Embase,Cochrane Library,PubMed and Web of Science were searched systematically,and randomized controlled trials(RCTs)of CBT in treating PGD was collected.Outcome indicators include sadness,depression,anxiety and somatization symptoms.RevMan 5.3 was used for Meta-analysis.Results A total of 7 articles were included with a total sample size of 528 cases.Meta-analysis results showed that the study group had lower scores than the control group for grief(SMD=-0.78,95%CI:-1.27～-0.29),depression(SMD=-0.45,95%CI:-0.73～-0.17)and anxiety symptom(SMD=-0.38,95%CI:-0.59～-0.18)with statistically significant differences.However,the difference of scores for somatization symptom between two groups was not significant(SMD=-0.01,95%CI:-0.26～0.25).Conclusion CBT may contribute to improving the symptoms of grief,depression and anxiety in PGD patients but unsatisfactory efficacy on somatization symptom.
