OBJECTIVE To explore the antidepressant mechanism of Wenyang jieyu granules （WYJYG） via the NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/apoptosis-associated speck-like protein containing a CARD （ASC）/Caspase-1 pathway. METHODS A rat model of depression was established by chronic unpredictable mild stress combined with single-housing for 42 consecutive days.The experiment set up blank group， model group， MCC950 （NLRP3 inflammasome inhibitor） group （10 mg/kg）， fluoxetine group （positive control，2.08 mg/kg），low-dose WYJYG（3.78 g/kg） and high-dose WYJYG group （7.56 g/kg），with 10 rats in each group. From the 22nd day of the experiment， rats in the fluoxetine group， low-dose and high-dose WYJYG groups were intragastrically administered with the corresponding drugs and intraperitoneally injected with an equal volume of normal saline. Rats in the MCC950 group were intraperitoneally injected with MCC950 at the corresponding concentration and intragastrically administered with an equal volume of distilled water. Rats in the blank group and model group were given an equal volume of distilled water by gavage and an equal volume of normal saline by intraperitoneal injection. All interventions were performed once a day for 21 consecutive days. Behavioral tests were conducted once a week. After the last administration， the contents of ASC， ionized calcium binding adaptor molecule 1 （Iba1）， interleukin-1β （IL-1β）， and IL-18 in hippocampal tissues were detected. The protein expressions of NLRP3， cluster of differentiation 68 （CD68）， Caspase-1， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein were determined， and neuronal apoptosis was observed. RESULTS After the last administration， compared with the model group， the open-field activity time was significantly prolonged （ P ＜0.05）， and the latency to feed in a novel environment was significantly shortened （ P ＜0.05） in rats of the high-dose WYJYG group. In hippocampal tissue， the contents of ASC， Iba1， IL-1β， and IL-18， as well as the protein expression levels of NLRP3， Caspase-1， and CD68， and the positive rate of neuronal apoptosis were all significantly decreased/downregulated （ P ＜0.05）. Bcl-2 protein expression was significantly upregulated （ P ＜0.05）， and the density of neuronal apoptosis-positive cells was significantly reduced （ P ＜0.05）. CONCLUSIONS WYJYG play on antidepressant role by inhibiting the NLRP3/ASC/Caspase-1 pathway， reducing microglia-mediated neuroinflammation， and inhibiting hippocampal neurons apoptosis.

ObjectiveTo construct and evaluate various machine learning models for predicting the risk of chronic obstructive pulmonary disease （COPD） in individuals， thereby providing data support for early screening and intervention. MethodsA total of 823 subjects were selected for this study， comprising 142 individuals in the high-risk group for COPD and 681 individuals in the low-risk group. Data collected included demographic characteristics， smoking history， symptoms （such as cough and shortness of breath）， and scores from the Chronic obstructive pulmonary disease screening questionnaire. Four machine learning algorithms—Logistic regression， random forest， support vector machine， and XGBoost—were utilized to construct risk prediction models. The performance of these models was assessed using 5-fold cross-validation， with evaluation metrics including accuracy， precision， recall， F1-score， area under the receiver operating characteristic curve （AUC）， and average precision （AP）. Furthermore， a feature importance analysis was performed. ResultsThe Logistic Regression model exhibited superior performance， achieving an AUC of 0.982 and an AP of 0.939. This was closely followed by the Random Forest model， which recorded an AUC of 0.975 and an AP of 0.890. Feature importance analysis revealed that smoking history， symptoms of shortness of breath， and body weight were significant predictors. All models demonstrated robust performance in identifying low-risk populations； however， variations were observed in their efficacy in identifying high-risk populations. ConclusionMachine learning models have proven effective in identifying individuals at high risk for COPD. Among these， the Logistic regression model exhibits the best overall performance， efficiently identifying high-risk populations and serving as a valuable clinical auxiliary screening tool. Various models， each with distinct performance characteristics， are suited to different clinical screening scenarios， thereby offering targeted decision-making support for the establishment of a hierarchical and intelligent COPD screening pathway.

Abstract The mental health assessment work for students in the UK is based on mental health promotion theory, employing a multidimensional approach to evaluate emotional disorders, conduct disorders, hyperactivity disorders, and other aspects across the entire educational continuum from preschool to university. Utilizing international validated standardized scales and customized questionnaires, the system has demonstrated significant preventive efficacy against student mental health issues. China stands to gain valuable insights from the UKs experience, particularly in implementing the Special Action Plan for Comprehensively Strengthening and Improving Students Mental Health Work in the New Era (2023-2025). Strategic adaptation could involve expanding assessment populations, refining evaluation criteria, standardizing measurement tools, and strengthening implementation protocols to systematically enhance Chinas students mental health assessment framework.

Aromatic Chinese medicinal essential oils are volatile oils extracted from aromatic Chinese herbs， which can prevent and treat respiratory infectious diseases through multiple synergistic mechanisms including pathogen inhibition， immune regulation， and inflammatory response regulation. Essential oils are primarily used externally on the body to prevent infections and alleviate symptoms through methods like inhalation， smearing， topical application， bathing， gargling or as a suppository. They can also be utilized in the environment for disinfection and air purification， through methods like diffusion， vaporization， or spraying. The external application of essential oils extracted from Chinese aromatic herbs has the advantages of convenience， quick absorption， and simultaneous influence on both the body and mind. However， there are still challenges and deficiencies in aspects such as the positioning of functions， indications， safety， and the research on the mechanism of action. It has been proposed to combine the theory of aromatic Chinese medicinals with the characteristics of essential oils， and formulate prescriptions of Chinese medicinal essential oils under the principles of traditional Chinese medicine syndrome differentiation， and prevent and treat respiratory infectious diseases efficiently， accurately， and safely， thereby expanding the clinical application of aromatic Chinese medicinals and the preventive theory of traditional Chinese medicine.

Objective To explore the application effect of blood pressure management based on the health belief model in patients with moyamoya disease after cerebral vascular reconstruction sur-gery.Methods From February to July 2024,210 patients with moyamoya disease who underwent cerebral vascular reconstruction surgery in our hospital were selected as study subjects.They were randomly divided into control group and intervention group,with 105 cases in each group.The control group received routine nursing care,while the intervention group applied blood pressure management based on the health belief model on the basis of routine nursing care.The postoperative cerebral hy-perperfusion syndrome and blood pressure control status of the two groups were compared,and the Health Belief Scale and the Mishel Uncertainty in Illness Scale were used to evaluate the effects before and after intervention.Results A total of 203 patients completed the study,including 100 cases in the control group and 103 cases in the intervention group.There were statistically significant differ-ences in the incidence of cerebral hyperperfusion syndrome and the proportion of patients with blood pressure higher than baseline data between the two groups(P＜0.05).After the intervention,there were statistically significant differences in the postoperative cerebral hyperperfusion syndrome status and blood pressure control status between the two groups(P＜0.05).After intervention,there were statistically significant differences in the scores of susceptibility and health motivation dimensions as well as the total score in the Health Belief Scale between the intervention group and the control group(P＜0.05).After the intervention,there were statistically significant differences in the scores of ambiguity and unpredictability dimensions as well as the total score in the Mishel Uncertainty in Ill-ness Scale between the intervention group and the control group(P＜0.05).Conclusion Blood pressure management based on the health belief model can effectively control blood pressure,reduce the incidence of cerebral hyperperfusion,improve health beliefs,and reduce the sense of uncertainty about the disease.

Objective To investigate lymphocyte interstitial infiltration condition and the changes of immune checkpoint gene expression in different stages of early esophageal cancer.Methods A ret-rospective analysis was conducted on the clinical data of 90 patients with early esophageal cancer.Based on the pathological depth of infiltration,they were divided into three types:T1a-M1,T1a-M2,and T1a-M3,with 30 cases in each type.Additionally,30 cases of paired normal mucosa tissues adja-cent to the cancer were selected.Hematoxylin-eosin(HE)staining was used to observe tissue morpholo-gy.Immunohistochemistry was employed to detect the expression of CD3,CD4,CD8,and CD20.Real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)was applied to measure the mRNA expression levels of immune checkpoint genes[programmed death ligand-1(PD-L1),cytotoxic T-lym-phocyte-associated protein 4(CTLA4),T-cell immunoglobulin and mucin domain-3(TIM-3),lympho-cyte activation gene 3(LAG3),programmed death receptor-1(PD-1),programmed death ligand-2(PD-L2),and T-cell immunoreceptor with Ig and ITIM domains protein(TIGIT)].Results As the stage of early esophageal cancer progressed,the ratio of tumor cells to lymphocytes increased.The number of CD3+T cells was greater than that of CD20+B cells,and the proportion of CD4+T cells among total T cells was higher than that of CD8+T cells(P＜0.001).The mRNA expression levels of gene in immune checkpoints in patients were elevated(P＜0.05).Compared with normal adja-cent tissues,the expression levels of PD-L1 mRNA,CTLA4 mRNA,TIM-3 mRNA,PD-1 mRNA,and TIGIT mRNA were elevated in patients with T1a-M1,T1a-M2,and T1a-M3 types(P＜0.05).Compared with normal adjacent tissues,the expression levels of LAG3 mRNA and PD-L2 mRNA were increased in patients with T1a-M2 and T1a-M3 types(P＜0.05).Conclusion The progres-sion of early esophageal cancer staging is correlated with increased immune checkpoint gene expres-sion and a decreased lymphocyte ratio,suggesting that changes in the immune microenvironment may be involved in tumor progression.

The results of agarose gel electrophoresis showed that the mouse genotype with only 415 bp band amplified was wild type(WT), the mouse genotype of the 449 bp band amplified only was TREM2-/-, and the mouse genotypes amplified with 415 bp and 449 bp double bands were heterozygous. qPCR results showed that compared with WT mice, the mRNA expression of TREM2 in heart and brain tissues of TREM2-/- mice was down-regulated(P-/- mice was reduced(P-/- mice. Conclusion TREM2-/- mice are successfully constructed and bred, a reliable genotype identification method is established, the genetic stability of the mouse model is verified, which will provide an important genetic animal model for the study of TREM2 gene function.

Diabetic nephropathy(DN)is a significant causative factor of end-stage renal disease globally,and its pathogenesis involves dysregulation of multiple cellular and hormonal pathways.Podocytes play crucial roles in the process of DN,with the extent of podocyte injury closely associated with key pathological manifestations of renal damage,such as proteinuria,glomerular filtration rate,and glomerulosclerosis.However,due to the complexity and interplay of mechanisms contributing to podocyte injury,such as oxidative stress,abnormal lipid metabolism,and mitochondrial damage,the precise mechanisms underlying podocyte injury remain incompletely understood.This review integrated the latest research findings from both domestic and international studies on the core mechanisms of podocyte injury in DN.Furthermore,this article summarized the implications of these mechanisms for DN treatment,particularly focusing on potential therapeutic targets and the development of related pharmacological interventions derived from targeting podocyte injury pathways,so as to provide a theoretical foundation for the development of clinical therapeutic strategies for DN.

With the deepening of the "Belt and Road" initiative, Central and Eastern Europe (CEE) presents new opportunities for the development of TCM. In recent years, CEE countries have made some progress in TCM by expanding legislation, establishing educational systems, and diversifying services. These advancements are attributed to cultural recognition, evolving health concepts, and government support. However, challenges persist in sustainability, legal adaptability, and a shortage of professional talents. To effectively tackle these challenges, this article proposed the following suggestions: gradual integration, initial implementation of non-pharmaceutical therapy-centered TCM health services to address legal adaptation issues; empowering with technology to alleviate talent shortage by launching remote medical service models; tailoring measures to local conditions and promote the sustainable development of the TCM industry by integrating regional characteristics; thereby promoting the robust development of TCM in the CEE regions.
