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.

Cilia,as cellular sensory organelles,actively partici-pate in and regulate cellular processes such as autophagy and metabolic breakdown during their generation and transportation.Autophagy,on the other hand,is a cell self-protection mecha-nism that maintains cellular homeostasis by clearing aggregates and damaged organelles.Combining recent research findings,this review comprehensively elucidates the bidirectional crosstalk between primary cilia and autophagy.Specifically,it highlights the crucial role of cilia-dependent signaling pathways in activa-ting cellular autophagy and how autophagy regulates cilia genera-tion and length by degrading specific ciliary proteins.Moreover,the dysregulation of primary cilia and autophagy is closely asso-ciated with the clinical manifestations and pathogenesis of vari-ous ciliopathy-related diseases such as polycystic kidney disease and tuberous sclerosis.In terms of pharmacotherapy,this review provides a comprehensive and in-depth overview of small mole-cule inhibitors targeting ciliogenesis,including cytoskeletal drugs and Hedgehog signaling pathway inhibitors.Despite the current limitations in clinical use,these drugs lay the groundw-ork for developing highly specific targeted small molecule inhibi-tors of ciliogenesis and for the treatment of ciliopathies and canc-ers.By systematically discussing ciliogenesis,autophagy,disea-ses and drugs,this review offers new insights for further elucida-ting the crosstalk between ciliogenesis and autophagy,exploring their pathological mechanisms in disease development,and de-veloping therapeutic strategies in the future.

Global procurement of health products is an important way for multilateral organizations in the health field to perform their functions.As one of the most important multilateral organizations in the global health field today,the Global Fund to Fight AIDS,Tuberculosis and Malaria occupies a huge share of the global procurement market for health products.This article introduces in detail the procurement methods of the Global Fund and the quality standards of its procured products;also it describes and analyzes the total amount of funds procured by the Global Fund,the types of procured health products,the main supply countries and their changing trends over time.Corresponding policy suggestions therefore are proposed for China to better participate in the governance of global health and for Chinese related companies to enter the international procurement market.

Objective:To analyze the epidemiological characteristics of imported malaria in Shaoxing City and provide scientific basis for formulating prevention and control measures against imported malaria.Methods:A retrospective analysis was conducted. Data on imported malaria cases reported in Shaoxing City from 2012 to 2024 were collected from the infectious disease reporting information system of China Center for Disease Control and Prevention, and the parasitic disease control information management system, including general information, epidemiological investigation reports and diagnosis/treatment status, to analyze their epidemiological characteristics.Results:From 2012 to 2024, there were 110 imported malaria cases in Shaoxing City, including 105 males and 5 females, with a sex ratio of 21 ∶ 1. The youngest patient was 21 years old and the oldest was 73 years old, with 72 cases (65.45%) in the 30-50 age group. The 110 malaria cases included 69 cases of falciparum malaria, 22 cases of vivax malaria, 15 cases of ovale malaria, 3 cases of quartan malaria, and 1 case of mixed infection. The infection sources were Africa (84.55%, 93/110) and Asia (15.45%, 17/110). Among all patients, there were 19 foreign nationals and 91 Chinese citizens. The main purposes of travel for Chinese citizens were labor work (67.03%, 61/91) and business (29.67%, 27/91). Areas with more reported cases were Zhuji City (32 cases), Keqiao District (27 cases), Xinchang County (19 cases) and Yuecheng District (19 cases). The peak months of onset were January, July and September, with 12, 12 and 18 cases respectively. The first medical visits were mainly at county-level hospitals, center for disease control and prevention at all levels and municipal hospitals, with diagnosis rates of 86.67% (52/60), 100% (21/21) and 12/15 respectively. Compared with cases without malaria history, cases with malaria history had shorter time from onset to diagnosis (median, 5.00 d vs. 2.00 d, Z =-2.40, P = 0.004). Conclusions:From 2012 to 2024, imported malaria in Shaoxing City was mainly falciparum malaria, with Africa being the main infection source. The peak incidence occurred in summer. Male young adult overseas workers were the high-risk population. The prevention and control of imported malaria in Shaoxing City should focus on preventing relapse after importation and cure.

United Nations(UN)agencies are key actors in global procurement of health products,with the United Nations Children's Fund(UNICEF)currently accounting for the largest share of UN procurement expenditures.This study developed a conceptual framework to analyze the processes of UN's global procurement for health products.Based on this framework,the study analyzed the mechanisms and key characteristics of UN procurement practices,identified potential challenges faced by Chinese products and suppliers seeking to engage with the UN's global procurement.The findings indicate a steady increase in the volume of Chinese products procured and their alignment with the UN's sustainable procurement policies.However,Chinese suppliers still face notable barriers,including gaps in technical standards,bidding and contracting capacities,and price competitiveness.In addition,the strategic compliance capabilities of Chinese suppliers and products,such as the ability to offer strategically valuable products and build long-term partnership,remains limited.Based on this,the study recommends that China enhance its participation and influence in the UN health procurements by stabilizing the production capacity,promoting knowledge-sharing among suppliers to enhance their engagement capabilities,and improving the long-term strategic competitiveness of Chinese enterprises in the global market.

Objective·To explore the antitumor effects and potential mechanisms of combining phosphoinositide 3-kinase,FYVE-type zinc finger containing(PIKfyve)inhibitor YM201636 with the stimulator of interferon genes(STING)agonist diABZI in STING pathway-deficient melanoma.Methods·The mRNA and protein expression levels of STING in human cancer cell lines were obtained from the Cancer Cell Line Encyclopedia(CCLE)and UniProt databases.Based on median expression values,melanoma cell lines with high STING mRNA but low protein expression were identified.Quantitative real-time PCR(qRT-PCR)and Western blotting were performed to validate STING mRNA and protein expression in human melanoma cells.The murine melanoma cell line YUMM1.7,characterized by low STING protein expression,was selected through Western blotting.The ability of YM201636 to restore STING protein expression in YUMM1.7 cells was evaluated.STING agonist diABZI was then applied in combination with YM201636 to analyze the synergistic tumor cell-killing effect through CCK-8 assay.Western blotting was used to detect the phosphorylation of TANK-binding kinase 1(TBK1)and interferon regulatory factor 3(IRF3),and qRT-PCR was used to evaluate type Ⅰ interferon expression.A mouse melanoma model was established and treated with YM201636,diABZI,or their combination.Tumor volume was measured,and treatment efficacy was assessed.RNA sequencing and immunofluorescence staining were performed to analyze immune cell infiltration in the tumor microenvironment.Results·Database analyses,qRT-PCR,and Western blotting confirmed that some human melanoma cell lines exhibited high STING mRNA expression but low STING protein levels.YM201636 significantly increased STING protein expression in YUMM1.7 cells(P<0.001).Combined treatment with YM201636 and diABZI significantly enhanced phosphorylation of TBK1 and IRF3(P<0.05),indicating effective activation of the STING signaling pathway.This combination also promoted the expression of type Ⅰ interferons(P<0.001)and enhanced tumor cell killing in vitro.In vivo,the combination therapy markedly suppressed melanoma growth compared to monotherapy.Immune profiling of the tumor microenvironment revealed significantly increased infiltration of CD4? T cells and CD8? T cells in the combination treatment group(P<0.05).Conclusion·The PIKfyve inhibitor YM201636 could restore STING protein expression in STING-deficient melanoma and enhance the antitumor efficacy of the STING agonist diABZI,offering a promising therapeutic strategy for tumors with defective STING signaling.
