Alzheimer's disease(AD)is a multifactorial degenerative disorder of the central nervous system that mainly manifests as cognitive dysfunction and loss of speech.In recent years,the zebrafish has attracted extensive attention because of its high homology with humans in terms of brain structure and function,nerve conduction,and pathogenic genes of AD.This article reviews the advantages of the zebrafish as an animal model of AD,covering topics in the pathogenesis of AD and the evaluation and screening of drugs for treatment of AD.The overall goal is to provide new insights into the pathogenesis of AD and development of novel drugs.

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To explore the relationship between emotional trauma and depressive symptoms.Methods:In November 2021, a total of 1 650 university students were assessed using scales including childhood trauma questionnaire (CTQ), distress tolerance scale (DTS), rumination response scale (RRS) and the depression anxiety stress scale (DASS). SPSS 20.0 and AMOS 25.0 software were used to analyze the data with Spearman correlation analysis, Mann-Whitney U test and mediation analysis. Results:The differences of DTS, RRS and DASS were significant between high and low trauma group(all P<0.01). Emotional trauma (16.70(6.09)) was negatively correlated with distress tolerance(10.95(2.15)) ( r=-0.26, P<0.01), and positively correlated with rumination(39.51(10.74)) and depression(4.93(5.76)) ( r=0.31, 0.38, both P<0.01). The testing of mediating effect indicated that emotional trauma had direct effect ( β=0.20, P<0.001) and indirect effect on depression through distress tolerance and rumination. Conclusion:Emotional trauma, distress tolerance and rumination are important factors influencing depression, and it could provide guidance for undergraduate psychological intervention of depression.

OBJECTIVE：To explore th e applicatio n of team situatio nal simulation education and teaching mode in clinical pharmacy teaching. METHODS ：A total of 60 clinical pharmacy interns were selected as the research objects ，and course disease was type 2 diabetes mellitus. Thirty interns were randomly selected as control group ，using traditional teaching mode ；other 30 interns were selected as trial group ，which carried out team situational simulation education and teaching mode. The teaching effects were evaluated by using the satisfaction of interns to the two modes ，the comprehensive score of graduation examination and the self-evaluation of learning effect. RESULTS ：Compared with traditional teaching mode ，team situational simulation education and teaching mode was conducive to stimulate the learning interest of interns ，improve their interpersonal communication ability ， cultivate teamwork spirit ，improve the awareness of humanistic care ，and cultivate the professional attitude of clinical pharmacists （P＜0.05）. Compared with control group ，the comprehensive score of trial group was dominantly increased （P＜0.001），and the scores of professional quality ，humanistic care and communication skills in the trial group were significantly higher than control group（P＜0.01）. In terms of self-evaluation of learning effect ，except for the pathogenesis of type 2 diabetes and the commonly used treatment regimens ，the self-evaluation scores of the other items in trial group were significantly higher than control group （P＜0.05 or P＜0.01）. CONCLUSIONS ：Team situational simulation education and teaching mode is superior to traditional teaching mode for clinical pharmacy teaching.
