Hepatitis D virus （HDV）， as a defective virus， relies on the envelope protein of hepatitis B virus （HBV） to complete replication and transmission. Chronic hepatitis B （CHB） patients comorbid with HDV infection may experience significant acceleration of liver disease progression and a significantly higher risk of serious complications such as liver cirrhosis and hepatocellular carcinoma （HCC） compared with the patients with CHB alone， which poses a serious threat to the life and health of patients. At present， the coverage rate of HDV screening needs to be improved， and some patients with HBV/HDV co-infection have not been found in time. Therefore， strengthening the understanding of HDV among clinicians， expanding the scope of HDV screening， identifying patients with infection in a timely manner， and performing standardized antiviral therapy and long-term follow-up management are of great significance for improving the prognosis of patients， reducing disease burden， improving the quality of life of patients， and achieving the global goal of “eliminating viral hepatitis as a public health threat by 2030”.

The scientific research and innovation capabilities of medical students are intrinsically linked to the sustained and high-quality development of national healthcare initiatives.Cultivating outstanding medi-cal students with independent scientific capabilities and innovative consciousness is a critical component in the education and training of high-level medical professionals.Our investigation revealed that within the imperfections of the cultivating model,some faculty and students at medical schools have an insufficient understanding of scientific research and innovation and lack motivation for engaging in such activities,which hinder the progression of scientific research activities.Consequently,we initiated a teaching practice and exploratory study on the"tutorial system"aimed at fostering medical students'scientific research and innovation abilities.Based on the principle of"research informing teaching,teaching and research advan-cing together,"this study implements a"tutorial system"coordinated by tutors,supplemented by graduate and undergraduate student mentors,to cultivate innovative thinking,stimulate interest in scientific re-search,and enhance practical and research skills among medical students.Through collaborative efforts within"scientific research innovation teams,"various educational methods—including preliminary re-search,in-class and extracurricular activities,intra-group and inter-group interactions,and theoretical and practical applications—are employed to improve and strengthen the cultivation of medical students'scientif-ic research and innovation abilities.This study aims to provide valuable references for optimizing medical education management systems and enhancing the quality of medical student training.

Choroidal neovascularization (CNV) is a common fundus neovascularization disease, which often leads to irreversible vision loss.The pathological mechanisms are extremely complex, involving the participation of a variety of cells and cellular contacts.Currently, there are still many deficiencies in the treatment of CNV.We are concerned that blood vessels are not only a " conduits" for transporting nutrients and metabolic waste, but also providing angiocrine factors for organ growth and development.A variety of tissue-specific vascular endothelial cells have been proved to be able to deliver a variety of cytokines under certain conditions, which act on surrounding cells and participate in the control of angiogenesis and homeostasis.Therefore, this review focuses on the research progress on the involvement of angiocrine in pericytes, retinal pigment epithelial cells, mononuclear macrophages, neutrophils and endothelial precursor cells in CNV through various forms such as extracellular vesicles, in order to provide new ideas for the treatment of CNV.

This study innovatively incorporates on-site teaching with the International Museum of Stomatology into the curriculum to establish an immersive and intuitive teaching mode,promoting education from both theoretical and practical dimensions.The teaching effect is comprehensively evaluated to explore the pathway to optimization.Multi-dimensional questionnaires are designed to collect feedback data from students on teaching satisfaction,knowledge mastery,professional identity,and humanistic literacy perception,fol-lowed by in-depth quantitative and qualitative analyses.The results demonstrate that this teaching mode significantly enhances literacy,playing a critical role in helping stomatological students fully understand professional knowledge and humanistic connotations while sub-stantially improving their professional identity.This teaching mode gives a direction for innovative stomatological education,holds sig-nificant importance for cultivating stomatological professionals with both clinical skills and humanistic literacy,possessing substantial potential for promotion,application,and further refinement.

Aim To explore the compatibility and po-tential mechanism of effective components of Biejia-Ezhu against triple negative breast cancer(TNBC)and verify it by experiments.Methods Effective compo-nents and targets of Biejia-Ezhu were obtained by TC-MSP and Swiss Target Prediction.Disease targets of TNBC were obtained from OMMI and GeneCards data-bases.The PPI network was constructed using STRING database.GO and KEGG path enrichment analysis was performed using DAVID database.Cytoscape3.9.1 software was used to construct the"drug-component-target-disease"network,screen key targets and compo-nents for molecular docking,and further verify the com-patibility of key components and targets in vitro.Re-sults ① A total of 71 effective components were iden-tified in the Biejia-Ezhu drug pair.There were 146 drug targets associated with the disease.A total of 113 signaling pathways were identified by KEGG analysis.The 71 potential active components of Biejia-Ezhu mainly acted on key targets such as mTORC1,ULK1,TNF,EGFR,ESR1,STAT3,HIF1A,and PTGS2.Mo-lecular docking results showed that glycine and curcu-min were the key active components of Biejia-Ezhu,and both had strong docking activity against key target proteins mTORC1 and ULK1.②The results of in vitro experiment showed that glycine combined with curcu-min significantly inhibited the proliferation and clonal formation ability of TNBC cells(P＜0.05),up-regula-ted the expression of autophagy marker LC3 Ⅱ/Ⅰ,down-regulated the expression of EGFR,down-regula-ted the expression of pathway protein mTORC1,p-mTOR,p-ULK1,and promoted the expression of path-way protein ULK1(P＜0.05).Conclusion The key component of Biejia-Ezhu against triple-negative breast cancer is glycine-curcumin,the mechanism of which may be related to the regulation of the mTORC1/ULK1 signaling pathway to promote autophagy.

Objective Auditory brainstem response(ABR)is an objective electrophysiological test that evalu-ates a patient's hearing,and the ABR is interpreted primarily by recognizing the latency of waves Ⅰ through Ⅴ.The latency of wave Ⅰ to wave Ⅴ has important reference value for clinicians to judge the status of patients' auditory neu-ral pathways,so accurate interpretation of the results of this examination is particularly important.However,the a-nalysis of the result of the ABR entirely depends on the auditory teacher's ability to recognize and interpret the hu-man eye,which makes it difficult for inexperienced auditory teachers to interpret ABR waveforms.In order to solve this problem,many scholars proposed to use machine learning(ML)model to objectively interpret ABR results.ML has strong learning ability and can independently complete an objective and accurate interpretation of ABR re-sults,which brings the dawn for the objective and accurate interpretation of ABR results.

Objective To observe the correlations of metabolite levels in medial prefrontal cortex(mPFC)and cancer-related depression(CRD)in patients with non-small cell lung cancer(NSCLC).Methods Totally 38 NSCLC patients were prospectively enrolled and divided into CRD group(n=23)and non CRD group(n=15)based on Hamilton depression scale(HAMD-17).Meanwhile,22 healthy individuals were taken as control group.1 H-MR spectroscopy was performed using Meshcher-Garwood point resolved spectroscopy sequence,then metabolite levels of mPFC were measured,and their correlations with HAMD-17 score were analyzed.Results Significant differences of gamma-aminobutyric acid(GABA)+/Water and glutamate/glutamine complex(Glx)/Water in mPFC were found among 3 groups.GABA+/Water in mPFC of CRD group was significantly lower than that of the other 2 groups(both P＜0.05),and Glx/Water in mPFC of CRD group was significantly lower than that of control group(P=0.034).In NSCLC patients,GABA+/Water in mPFC was negatively correlated with HAMD-17 score(r=-0.491,P=0.002).Conclusion GABA+/Water in mPFC was negatively correlated with HAMD-17 score in NSCLC patients.

Objective To explore the value of spectral CT quantitative parameters combined with clinical and CT features for predicting lymphovascular invasion(LVI)of colorectal cancer.Methods Clinical,pathological and preoperative abdominal spectral CT data of 98 colorectal cancer patients were retrospectively analyzed.According to pathological results,the patients were divided into LVI group(n=36)and non-LVI group(n=62).Univariate and multivariate logistic regression were used to compared clinical,pathological,conventional CT manifestations and spectral CT quantitative parameters between groups to screen independent predictors for LVI of colorectal cancer,and then a regression model was constructed.Receiver operating characteristic(ROC)curves were drawn,and the area under the curves(AUC)were calculated to evaluate the predictive efficacy of each single independent predictor and regression model for predicting LVI of colorectal cancer.Results Serum carbohydrate antigen 724,CT showed periintestinal fat infiltration and effective atomic number(Zeff)at venous phase were all independent predictors of LVI of colorectal cancer(OR=4.723,7.301 and 18.912,all P＜0.05).AUC of the above independent predictors was 0.582,0.723 and 0.691,respectively,while of the regression model was 0.837.Conclusion Spectral CT quantitative parameters combined with clinical and CT features could effectively predict LVI of colorectal cancer.

Objective:To explore the efficacy and adverse reactions of CAG regimen combined with venetoclax,chidamide,and azacitidine in the treatment of elderly patients with acute myeloid leukemia(AML).Methods:15 elderly AML patients aged ≥ 60 years old who were admitted to the Hematology Department of our hospital from May 2022 to October 2023 were treated with the CAG regimen combined with venetoclax,chidamide and azacitidine,and the efficacy,treatment-related adverse events,overall survival(OS)and event-free survival(EFS)were analyzed.Results:After one course of treatment,11 out of 15 patients achieved complete response(CR),3 patients achieved CR with incomplete hematologic recovery(CRi),and 1 patient died due to prior infection before efficacy evaluation,and the overall response rate(ORR)was 93.3％(14/15).The median follow-up time was 131(19-275)days,with median OS and EFS both remaining unreached.Next-generation sequencing(NGS)analysis showed that among the 15 patients,13 were detected with gene mutations,and there were 7 genes with mutation frequencies of more than 10％,including ASXL1(4 cases),RUNX1(4 cases),BCOR(3 cases),DNMT3A(3 cases),STAG2(2 cases),IDH1/2(2 cases),and TET(2 cases).Among the 13 patients with detectable mutations,12 patients achieved composite response(CR+CRi).The average recovery time of white blood cell count was 14.6 days after chemotherapy,and the average recovery time of platelets was 7.7 days after chemotherapy.The main adverse event was myelosuppression,with 10 patients accompanied by infection.Except for 1 patient who died due to septic shock during chemotherapy,no patients experienced serious complications such as heart,liver,or kidney damage during the treatment process.Conclusion:The CACAG+V regimen,which combines the CAG regimen with venetoclax,chidamide,and azacitidine,can be applied in the treatment of elderly AML patients,demonstrating good safety and induction remission rate.
