Objective:To select the differential prognostic lactic acid metabolism-related genes(LRGs)of the head and neck squamous cell carcinoma(HNSCC)to construct the LRGs prognostic model of HNSCC,and to clarify the potential mechanism.Methods:The HNSCC gene expression and clinical data were obtained from The Cancer Genome Atlas(TCGA)and Gene Expression Omnibus(GEO)Databases,the LRGs were identified through GeneCards Database,and R software was used to screen out the LRGs of HNSCC;univariate Cox regression analysis was used to identify prognosis-related genes;two different subtypes were identified based on the prognostis-related LRGs;Kaplan-Meier(K-M)curve analysis was used to compare the prognosis of the patients between two groups;CIBERSORT algorithm was used to perform the immuno-correlation analysis between two groups;multivariate Cox regression analysis and LASSO regression analysis were used to construct the prognostic model;receiver operating characteristic curve(ROC)and K-M survival curve were used to assess the relationship between LRGs and survival and prognosis of the HNSCC patients.The prognostic model was validated by GSE27020,GSE41613,and GSE65858 datasets.The experiment were grouped based on risk score,and immune-related analysis and tumor score analysis were performed.Results:The TCGA Database differential analysis results showed that 1 196 LRGs were identified from HNSCC samples;univariate Cox regression analysis selected 27 differentially expressed genes(DEGs)associated with the prognosis of the HNSCC patients.Two different LRGs subtypes(Group 1 and Group 2)were identified according to the prognosis-related genes.The K-M survival curves results showed that the overall survival(OS)of the patients in Group 2 was significantly higher than that in Group 1,and the immune cell expression amount of the patients in Group 2 was also higher than that in group 1.The multivariate Cox regression and LASSO regression analysis results screened out 9 LRGs,including hypoxanthine phosphoribosyltransferase 1(HPRT1),amyloid precursor protein(APP),glycogen phosphorylase L(PYGL),urokinase-type plasminogen activator(PLAU),cannabinoid receptor 2(CNR2),stanniocalcin 2(STC2),nucleotide binding oligomerization domain-like receptor protein 1(NLRP1),integrin-linked kinase(ILK),and forkhead box B1(FOXB1);the prognostic model was constructed.The K-M and ROC curve results indicated that the expression levels of above 9 genes were associated with the survival and prognosis of the HNSCC patients,providing good 1-year,2-year,and 3-year survival prediction effect,and the area under ROC curve(AUC)values were all greater than 0.650.Furthermore,the predictive ability of the prognosis model was validated in GSE27020,GSE41613,and GSE65858 datasets.The patients classified based on the risk scores had distinguishable immune statuses.Conclusion:The differentially expressed LRGs of HNSCC screened by bioinformatics methods are related to the survival and prognosis of the HNSCC patients;the prognostic model constructed by 9 LRGs can predict the survival status and treatment response of the HNSCC patients.

The study was carried out to understand the changes in the ethical cognition status of laboratory animals and the effectiveness of laboratory animal ethics education among medical students in Xiangya School of Medicine of Central South University (CSU), and provide new enlightenment for further strengthening the ethical education of laboratory animals. In the study, the same self-compiled questionnaire was used to investigate the ethical cognition of experimental animals among medical students in Xiangya School of Medicine of CSU in 2011 and 2021, and 359 and 363 questionnaires were collected respectively. Through comparative analysis of the questionnaire results before and after ten years, it was found that medical students’ animal experiment operation and attitudes towards laboratory animals, cognition of experimental animal ethics knowledge and their attitude to animal experiment ethics education were significantly improved. It showed that the state of experimental animal ethics cognition among medical students in Xiangya School of Medicine of CSU had improved significantly in recent 10 years, but the cognition of experimental animal ethics knowledge was higher than the actual behavior of caring for experimental animals, and there was the phenomenon of "separation of knowledge and action". The ethics education of experimental animals needs to pay more attention to the development of students’ behavior of caring for experimental animals.

Objective:To analyze the change of differential genes and signaling pathways in high glucose induced BV2 cells, and to explore the mechanism of transgelin-2 (TAGLN2) regulating cellular inflammatory response and metabolic process.Methods:An experimental study. The cultured BV2 cells were divided into mannitol treatment (Man) group, glucose treatment (Glu) group, overexpression control Glu treatment (Con) group, overexpression TAGLN2 Glu treatment group, silence control Glu treatment (shCon Glu) group, and silence TAGLN2 Glu treatment (shTAGLN2 Glu) group. Cells in the Man group were cultured in modified Eagle high glucose medium (DMEM) containing 25 mmol/L mannitol and 25 mmol/L glucose, cells in other groups (Glu group, Con Glu group, TAGLN2 Glu group, shCon Glu group and shTAGLN2 Glu group) were cultured in DMEM medium containing 50 mmol/L glucose. After 24 hours of cells culture, transcriptome sequencing of cells in each group were performed using high-throughput sequencing technology, and significantly differentially expressed genes (DEG) were screened. |log 2 (fold change)|≥1 and P≤0.05 were adopted as criteria to screen for DEG. Gene Ontology (GO) function enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and protein-protein interaction network analysis were performed. Real-time polymerase chain reaction (RT-PCR) was used to detect the relative expression level of DEG mRNA. The data between groups were compared by independent sample t-test. Results:When compared with Man group, a total of 517 differentially expressed genes were screened in Glu group, which including 277 up-regulated genes and 240 down-regulated genes. KEGG pathway enrichment analysis showed that the up-regulated genes were significantly enriched in immune system processes such as nuclear factor (NF)-κB signal pathway, Jak-signal transducers and activators of transcription (STAT) signal pathway, while down-regulated genes were significantly enriched in glycosaminoglycan degradation and glyceride metabolic pathway. Compared with Con Glu group, a total of 480 DEG were screened in TAGLN2 Glu group, among which 147 up-regulated and 333 down-regulated genes were detected. Up-regulated genes were significantly enriched in the metabolic processes of fatty acid, glyceride and pyruvate, while down-regulated genes were significantly enriched in immune system processes such as NF-κB signal pathway, Jak-STAT signal pathway and tumor necrosis factor (TNF) signal pathway. Compared with shCon Glu group, a total of 582 DEG were screened in shTAGLN2 Glu group, among which 423 up-regulated and 159 down-regulated genes were detected. Up-regulated DEG were significantly enriched in immune system processes such as TNF signal pathway and chemokine signal pathway, while down-regulated DEG were significantly enriched in pattern recognition receptor signal pathway. RT-PCR results showed that the relative expression levels of DEG mRNA Card11 ( t=13.530), Icos ( t=3.482), Chst3 ( t=6.949), Kynu ( t=5.399), interleukin (IL)-1β ( t=2.960), TNF-α ( t=5.800), IL-6 ( t=3.130), interferon-γ ( t=7.690) and IL-17 ( t=6.530) in the TAGLN2 Glu treatment group were decreased significantly compared with Con Glu group, and the difference was statistically significant. Conclusion:TAGLN2 can inhibit glucose induced microglia inflammation by NF-κB and Jak-STAT signaling pathways, Card11, Icos, Chst3 and Kynu play an important role in the anti-inflammatory process of TAGLN2.

In recent years， the incidence of colorectal cancer has been rising in China， and with the promotion of early screening and early diagnosis， most colorectal cancers are able to achieve long-term survival through timely diagnosis and treatment. Nevertheless， 30%-70% of patients with early to mid-stage colorectal cancer after radical surgery still have psychological problems such as anxiety， depression， and fear of recurrence and metastasis， and they hope to seek help from traditional Chinese medicine（TCM） treatment. In order to further standardize the integrated traditional Chinese and western medicine psychological rehabilitation interventions of stage Ⅰ-Ⅲ colorectal cancer after radical surgery， and to improve the diagnosis and treatment level， under the support of the pilot project of clinical collaboration between Chinese and western medicine for major and difficult diseases of National Administration of TCM， experts in oncology， integrated Chinese and western medicine， psychology， surgery， nursing， evidence-based medicine and other disciplines from 10 units nationwide participated in the work， led by Xiyuan Hospital，China Academy of Chinese Medical Sciences and Beijing Cancer Hospital. Based on the methodology and process of guideline development of the World Health Organization Handbook for Guideline Development and the Regulations for Group Standards of China Association of Chinese Medicine， the Guidelines for Psychological Rehabilitation Intervention Combined Integrated Traditional Chinese and Western Medicine After Radical Surgery for Early and Middle Stage Colorectal Cancer have been developed according to the current best evidence， extensive consultation with clinical experts and following the situation of current clinical practice. The guideline provides the psychological characteristics， the needs and willingness to accept psychological rehabilitation， the interventions for psychological rehabilitation， evaluation of efficacy， follow-up review， educational guidance and others of patients with stage Ⅰ-Ⅲ colorectal cancer after radical surgery. It can provide guidance for TCM（integrated Chinese and western medicine） clinicians and psychologists engaged in the psychological rehabilitation of integrated Chinese and western medicine oncology， especially for doctors in primary medical institutions.

【Objective:】 To explore the practice experience of narrative medicine among postgraduates majoring in Traditional Chinese Medicine (TCM) and its impact on their professional identity. 【Methods:】 A total of 56 first-year master’s and doctoral degree students majoring in TCM at a university were selected through purposive sampling for a 16-hour narrative medicine course training and 4 weeks of clinical practice in narrative medicine. They were asked to complete an open-ended writing assignment on their practical experience after this clinical practice. Subsequently, the topic analysis method in qualitative research was used to analyze their writing contents. 【Results:】 After learning narrative medicine, the students’ practical experience in clinical practice included 3 major themes and 9 sub-themes: wide application range (all diagnosis and treatment stages, multiple departments, and disease types), integration of multiple communication skills and diagnosis and treatment methods (communication skills, psychological techniques, reflection, and TCM humanistic diagnosis and treatment methods), and increasing professional identity (achieving mutual healing, building the harmonious doctor-patient relationship, and enhancing confidence in TCM). The themes were further integrated to form the relationship between the narrative medical practice cycle and professional identity, and presented in the form of charts. 【Conclusion:】 By exploring the narrative medical practice experience among TCM postgraduates, it was found that through the use of multiple methods and techniques in the entire diagnosis and treatment stage and multi-disciplinary diseases, it is possible to harmonize the doctor-patient relationship, achieve mutual healing, and enhance confidence in TCM. These internalized recognition and sense of achievement contributes to improving professional identity, which may provide new ideas for the development of professional identity for medical students in China and the exploration of the localization of narrative medical practice.

Europe occupies an important position in the world herbal medicine market. The registration of Traditional Chinese Medicine (TCM) in EU is of great significance to the internationalization of TCM. The European Medicines Agency (EMA) has designed a relatively complete management system and regulatory guidelines for the registration and supervision of herbal medicinal products. The promulgation of the DIRECTIVE 2004/24/EC (2004 / 24 / EC) indicates that TCM could enter the EU market through simplified registration. Based on the registration conditions, registration authority and document guideines of Traditional Herbal Medicinal Products (THMPs) in EU, this paper analyzes the application requirements of simple registration of traditional herbal products in EU, and provides suggestions for the simplified registration of TCM in EU according to the registration requirements of medicinal history, quality requirements and application data format.
