OBJECTIVE To investigate the use of drugs and the development of pharmaceutical care in the tight medical alliance （shorted for “medical alliance”） of Wanzhou District of Chongqing， and provide reference for the further construction of the medical alliance. METHODS A survey form was designed and distributed to 21 constituent units （5 leading units and 16 member units） of 5 medical alliances in Wanzhou District of Chongqing. The statistical analysis was conducted in aspects of basic drug allocation and use， pharmaceutical personnel team construction， the development of pharmaceutical care， and rational use of antibiotics. RESULTS Among the 21 constituent units， 4 leading units and 14 member units achieved the target for the proportion of essential drug procurement varieties， with a total compliance rate of 85.71%； 4 leading units and 13 member units achieved the target for the proportion of national essential drug allocation and usage amount， with a total compliance rate of 80.95%. The proportions of personnel with doctoral degrees in the 5 leading units and 16 member units were 1.71% and 0 respectively， and the proportions of personnel with senior professional titles were 8.56% and 1.63%， respectively. A total of 5 pharmacy or pharmaceutical combined outpatient clinics were set up in the 21 medical alliance units， and 5 clinical pharmacy information service platforms were established； all 5 leading units were able to regularly carry out clinical pharmacy projects， while only 4 out of 16 member units had conducted medical order review and evaluation. The proportions of irrational use of antibiotics in outpatient prescriptions and inpatient medical records of the 16 member units （4.81%， 5.21%） were significantly higher than those of the 5 leading units （2.80%， 4.00%）. CONCLUSIONS The allocation and usage of national essential drugs in 21 constituent units from Wanzhou District of Chongqing are both in good standing. However， the data on the allocation of pharmaceutical professionals and the number， qualifications， and job titles of clinical pharmacists in member units are generally low. Moreover， the pharmaceutical service projects and service quality in member units need to be further improved.

Introduction: The Theory of Planned Behavior (TPB) construct is recommended by the World Health Organization to assess intention for vaccination; however, there is yet a validated instrument in the context of booster dose Covid-19 vaccination in Malaysia. The purpose of the present study is to translate and investigate the factorial validity and internal reliability of the TPB construct for booster dose Covid-19 vaccination (TPB-BDV) questionnaire in Malaysia. Materials and methods: In the pre-testing of the study, five experts and 40 Malaysian adults respectively rated the content and validity index of all 11 items of the translated questionnaire in Malay version. Next, 160 Malaysian adults completed the Malay version of Theory of Planned Behavior- Booster Dose Vaccination (TPB-BDV) questionnaire via online. Results: In the pre-testing phase, Content Validity and Face Validity Index for 10 items in Malay version of TPB-BDV achieved cutoff mean score >3.0 for relevancy, clarity, ambiguity, and simplicity. Meanwhile, Item 8 scored low on relevancy. In the main study, exploratory factor analysis suggested three factors consisting of a final 10 items (without Item 8) which accounted for 74.0% of the total variance. The three factors were Attitude (5 items), Subjective Norms (3 items), and Perceived Behavioral Control (2 items). The internal reliability ranged from a = 0.83 to a = 0.93, with an overall value of a = 0.90. Conclusion: The findings suggest that the 10-items Malay version of TPB-BDV is valid and reliable to measure the individual decision in taking the Covid-19 booster-dose vaccine among Malaysian adult population.

Objective: To investigate the feasibility of magnetic anastomosis for uretero-ileal anastomosis using experimental rabbit models. Methods: Six experimental rabbits were used as the models.The lower part of the left ureter was cut with scissors，the daughter magnet (DM) was placed in the middle of the ureter，and the distal end of the ureter was ligated.After that，the ileum wall was opened，the parent magnet (PM) was inserted through it，the positions of the PM and DM were adjusted so that their ends were attracted to each other，and then ileum wall incision was sutured.The operation time，intraoperative blood loss，postoperative complications and magnet discharge time were recorded.Two weeks after operation，left ureterography was performed to obtain the specimens of the uretero-ileal anastomosis，and to observe the patency of the anastomosis.The formation of the anastomosis was observed with naked eyes and light microscope. Results: Uretero-ileal magnetic anastomosis was performed successfully in 6 experimental rabbits.The operation time was 28-39（32.50±3.94） min，and the intraoperative blood loss was less than 5 mL.The rabbits recovered well after operation，and no complications were observed.All animals survived to the end point of observation.The disconnection time of magnet after operation was 9-13(10.83±1.72) days.The gross specimen showed that the anastomosis was patent.The histological observation showed that the mucosa of the anastomosis was continuous and smooth，and the anastomosis was well formed. Conclusion: Magnetic anastomosis is feasible for uretero-ileal anastomosis with simple operation and good anastomosis formation.After further experimental verification，this technique is expected to be used in clinical practice.

Objective: To explore the current situation and related factors of AIDS discrimination among junior medical students in Jiangxi Province, so as to provide a reference for effective AIDS anti discrimination intervention measures in medical colleges. Methods: Using a convenience sampling approach, 2 484 medical students were selected from five universities in Jiangxi Province from July to August 2023. An anonymous survey was conducted using a general information questionnaire, a AIDS knowledge questionnaire, and the Chinese version of Zelaya s AIDS Stigma Scale. Independent sample t-tests and analysis of variance were carried out to analyze the level of AIDS discrimination among medical students with different characteristics. Multiple stepwise regression analysis was performed to identify the related factors of AIDS discrimination. Results: The total score of AIDS discrimination among medical students was (2.55±0.67). The dimension with the highest score was fear of contracting the disease (2.89±1.01). The results of the multiple stepwise regression analysis showed that the factors related to AIDS discrimination included gender ( β = -0.17 ), grade ( β =-0.08), being an only child or not ( β =-0.04), whether knowing about AIDS knowledge or not ( β =0.22), willingness to use condoms during sexual activity ( β =0.07), willingness to participate in school sexual health knowledge based activities ( β =0.05) and the perceived importance of selfhealth ( β =0.11) ( P <0.05). Conclusions AIDS discrimination is prevalent among junior medical students in Jiangxi Province. Efforts should be undertaken to enhance humanistic education and relevant knowledge dissemination among junior medical students to reduce the level of AIDS discrimination.

Objective:To investigate the toxic effect of chlorambucil combined with ibrutinib on mantle cell lymphoma(MCL)cell line Jeko-1 and its related mechanism.Methods:The MCL cell line Jeko-1 was incubated with different concentrations of chlorambucil or ibrutinib or the combination of the two drugs,respectively.CCK-8 assay was used to detect the proliferation of the cells,and Western blot was used to measure the protein expression levels of BCL-2,caspase-3,PI3K,AKT and P-AKT.Results:After Jeko-1 cells were treated with chlorambucil(3.125,6.25,12.5,25,50 μmol/L)and ibrutinib(3.125,6.25,12.5,25,50 μmol/L)alone for 24,48,72h respectively,the cell proliferation was inhibited in a time-and dose-dependent manner.Moreover,the two drugs were applied in combination at low doses(single drug inhibition rate＜50％),and the results showed that the combination of two drugs had a more significant inhibitory effect(all P＜0.05).Compared with the control group,the apoptosis rate of the single drug group of chlorambucil(3.125,6.25,12.5,25,50 μmol/L)and ibutinib(3.125,6.25,12.5,25,50 μmol/L)was increased in a dose-dependent manner.The combination of the two drugs at low concentrations(3.125,6.25,12.5 μmol/L)could significantly increase the apoptosis rate compared with the corresponding concentration of single drug groups(all P＜0.05).Compared with control group,the protein expression levels of caspase-3 in Jeko-l cells were upregulated,while the protein expression levels of BCL-2,PI3K,and p-AKT/AKT were downregulated after treatment with chlorambucil or ibrutinib alone.The combination of the two drugs could produce a synergistic effect on the expressions of the above-mentioned proteins,and the differences between the combination group and the single drug groups were statistically significant(all P＜0.05).Conclusion:Chlorambucil and ibrutinib can promote the apoptosis of MCL cell line Jeko-1,and combined application of the two drugs shows a synergistic effect,the mechanism may be associated with the AKT-related signaling pathways.

Since the late 1990s, online e-learning has offered unparalleled convenience and affordability, becoming increasingly popular among pathologists. Traditional learning theories have been successfully applied to web/mobile-based learning systems, with mobile technologies even enhancing conventional offline education. In cytopathology, hands-on microscope training has traditionally been paramount, complemented by real-case presentations and lectures. However, the coronavirus disease 2019 (COVID-19) pandemic disrupted regular academic activities, making online e-learning platforms essential. We designed a web/mobile-based learning platform to enhance continued medical education in cytopathology at various levels, particularly during the era of COVID-19 and beyond. Since 2021, we have integrated curriculum materials, virtual education files, and whole-slide images (WSIs) of cytopathology, submitted from over 200 institutions across Korea, with the support of numerous instructors. We develop a new e-learning platform named “CytoAcademy” composed of a basic session for each organ and level across the range of morphologic findings; on-demand lectures to enhance cytopathologic knowledge; WSI archives that allow users to explore various histologically confirmed cases; and a self-assessment test to help organize diagnostic knowledge acquired through the web/mobile-friendly learning system. The platform provides not just an opportunity to achieve a correct diagnosis, but also a learning experience based on problem-solving point. Members interact, identify their deficiencies, and focus on specific educational materials. In this manner, all participants can actively engage in creating and maintaining knowledge and foster a proactive approach to learning.
