OBJECTIVE: To develop a digital intelligent multimodal shift handover system for the intensive care unit (ICU) and evaluate its application effect in ICU shift handovers. METHODS: A research and development team was established, consisting of 1 department director, 1 head nurse, 3 information technology engineers, 3 nurses, and 2 doctors. Team members were assigned responsibilities including overall coordination and planning, platform design and maintenance, pre-application training, collection and organization of clinical feedback, and research investigation respectively. A digital intelligent multimodal shift handover system was developed for ICU based on the Shannon-Weaver linear transmission model. This innovative system integrated automated data collection, intelligent dynamic monitoring, multidimensional condition analysis and visual reporting functions. A cloud platform was used to gather data from multi-parameter vital signs monitors, infusion pumps, ventilators and other devices. Artificial intelligence algorithms were employed to standardize and analyze the data, providing personalized recommendations for healthcare professionals. A self-controlled before-after method was adopted. Before the application of the ICU digital intelligent multimodal shift handover system (from December 2023 to March 2024), the traditional verbal bedside handover was used; from June 2024 to March 2025, the ICU digital intelligent multimodal shift handover system was applied for shift handovers. Questionnaires before the application of the shift handover system were collected in April 2024, and those after the application were collected in April 2025. The shift handover time, handover quality (scored by the nursing handover evaluation scale), satisfaction with doctor-nurse communication (scored by the ICU doctor-nurse scale) before and after the application of the handover system were compared, and nurses' satisfaction with the shift handover system (scored by the clinical nursing information system effectiveness evaluation scale) was investigated. RESULTS: After the application of the ICU digital intelligent multimodal shift handover system, the shift handover time was significantly shorter than that before the application [minutes: 20 (15, 25) vs. 30 (22, 40)], the handover quality was significantly higher than that before the application [score: 84.0 (78.0, 88.5) vs. 71.0 (55.0, 79.0)], and the satisfaction with doctor-nurse communication was also significantly higher than that before the application (score: 84.58±6.79 vs. 74.50±11.30). All differences were statistically significant (all P < 0.05). In addition, the nurses' system effectiveness evaluation scale score was 102.30±10.56, which indicated that nurses had a very high level of satisfaction with the ICU digital intelligent multimodal shift handover system. CONCLUSIONS The application of the ICU digital intelligent multimodal shift handover system can shorten the shift handover time, improve the handover quality, and enhance the satisfaction with doctor-nurse communication. Nurses have a high level of satisfaction with this system.

Objective:To evaluate the feasibility of transjugular transcatheter tricuspid valve replacement (TTVR) using the LuX-Valve Plus system (Ningbo Jenscare Scientific, China) for the treatment of severe tricuspid regurgitation in real-world clinical settings.Methods:This prospective study enrolled 81 patients with severe ricuspid regurgitation (≥3+) who underwent TTVR with the LuX-Valve Plus system at the Department of Cardiology, West China Hospital of Sichuan University between May 2022 and March 2024. Among them, 44 patients were from a compassionate-use study, and 37 were from two premarket clinical trials. Baseline clinical data, preprocedural imaging, procedural outcomes, and postprocedural follow-up data were collected. The primary endpoint events included device success, procedural success, and 30 d composite adverse events.Results:The age of the cohort was (74.5±7.8) years, with 54 females (67%). Device success and procedural success rates were both 90% (73/81). Post-procedural tricuspid regurgitation improved, with a 6% (5/81) incidence of moderate-to-severe paravalvular leakage. The rate of permanent pacemaker implantation was 12% (10/81), of which 5% (4/81) had pre-existing indications for pacemaker implantation. Major bleeding events occurred in 10% (8/81) of patients, and the 30 d composite endpoint rate was 25% (20/81).Conclusion:TTVR using the LuX-Valve Plus system demonstrates promising feasibility for high-risk surgical patients with severe tricuspid regurgitation, effectively reducing or eliminating regurgitation with acceptable safety. However, challenges remain in reducing risks of major adverse events, including permanent pacemaker implantation and severe bleeding.

Shift handover is a process of transferring power and responsibility between medical staff,and it is also a basic part of medical activities.Intensive care unit(ICU)is the core area for the treatment of critically ill patients,with complex patient conditions and fine and diverse treatment.If clinical information cannot be shared accurately and in time,it will lead to the delay of the patient's condition,diagnosis and treatment plan.At the same time,the omission of handover information and communication problems can easily lead to safety risks,prolonged hospital stay and increased number of readmissions.Therefore,as one of the important links in ICU diagnosis and treatment and nursing work,accurate,complete and effective handover can ensure the rapid and accurate transmission of patient information and promote the smooth development of diagnosis and treatment and nursing work.This paper reviews the application scope of ICU shift handover model,analyzes the main characteristics,application status and application effects of ICU shift model,and discusses the problems and shortcomings of the existing ICU shift model,in order to provide a reference for further optimizing the quality of ICU shift.PRISMA extension for scoping reviews(PRISMA-ScR)as methodological guidance,we conducted a systematic search across major databases including PubMed,Web of Science,Embase,Cumulative Index to Nursing and Allied Health Literature(CINAHL),and Chinese databases(Wanfang,CNKI,Chinese Medical Association,CBM)using both subject headings and free-text terms).The search time limit was from the establishment of the database to July 18,2024.The preliminary retrieved literature bibliographer was imported into Endnote 20.0 software,and the obtained literature was selected and screened by two researchers.A total of 14 articles were included,of which 10 were from China and 4 were from the United States,and all were published between 2012 and 2022.The analysis showed that the ICU shift mode mainly included improved shift mode,group system shift mode,anti-shift mode,checklist type shift sheet mode and electronic information ICU shift.The shift mode showed diversified characteristics,optimized staffing to a certain extent,standardized the specific content and process of shift,and improved the quality of shift.Significant advances have been made in information delivery and quality of care.However,domestic research is mostly focused on the improvement of the shift mode,which faces the shortcomings of increasing workload,coordination and communication challenges,and the scientification and standardization of tools.Electronic information technology makes up for the shortcomings of information omission in the traditional shift process through the advantages of automatic data collection and information collection,and shows positive results in the process of shift.Future research needs to further explore the basis of not increasing the load of ICU clinical medical staff,ensuring the efficiency of shift and normal work flow.Pay attention to the intelligent,standardized and personalized construction of ICU shift,improve the quality of diagnosis and treatment and nursing,and ensure the safety of patients.

Objective To investigate the material basis and antitumor mechanism of Marsdenia tenacissima (MT) on hepatocellular carcinoma (HCC) by bioinformatics, network pharmacology and molecular docking technology. Methods Active ingredients of MT were collected by literature search and screened by Swiss ADME website, which targets were predicted by Swiss Target Prediction. The chip data of HCC (GSE147888) were downloaded from the NCBI Gene Expression Omnibus (GEO) database. Differentially expressed genes were screened by R software. HCC-related targets were collected from the Genecards and OMIM databases. The Venny online tool was used to obtain the intersection of the herbal medicine targets and the disease targets. Subsequently, drug-target network and protein–protein interaction (PPI) network were constructed by Cytoscape software and String platform. GO enrichment analysis and KEGG pathway analysis were performed to analysis the functions and pathways enriched by key genes. The expression of key genes in HCC and its effect on survival were analyzed by the GEPIA database. The Human Protein Atlas (HPA) was used to analyze the immunohistochemical expression of key genes in HCC. Finally, molecular docking was carried out to investigate interactions between the top five targets and their related active compounds. Results A total of 50 active components were screened and 12 common targets were identified related to MT and HCC. Scutellarein-4-Methylether, Tenasogenin, Sinapic Acid, Dresgenin and Kaempferol were considered as the critical components. JUN, MMP9 and PTGS2 were recognized as key therapeutic targets. The GO analyses demonstrated that key targets mainly involved in the process of gene silencing and inflammatory response. KEGG analysis suggested that key targets were enriched in TNF signaling pathway and IL-17 signaling pathway. Survival analysis by the GEPIA showed significant differences in the expression of ESR1, MMP1, MMP9, JUN, and PPARG between high and low risk groups. Immunohistochemical results showed that ESR1 and MMP9 were differentially expressed in normal and hepatocellular carcinoma tissues. The molecular docking results verified that the drug active ingredient could be stably bound to the target protein. Conclusion This study reflected the multi-component, multi-target and multi-pathway characteristics of the MT in the treatment of HCC, which could provide a scientific basis for the clinical application of MT in HCC.

The 2030 Immunization Agenda of the World Health Organization （WHO） states that everyone in the world should fully benefit from vaccines to achieve good health and well-being. With the ever-changing disease spectrum and the improvement of residents' health literacy， relying solely on vaccines included in the National Immunization Program （NIP） is insufficient to meet the current requirements for disease prevention and control. Non-NIP vaccines play an important role in meeting people's diverse needs. Vaccine hesitancy is a global issue and an important factor affecting vaccine uptake. By reviewing relevant studies on vaccine hesitancy in recent years， this paper summarized different vaccination situations， current situation of vaccine hesitancy， measuring tools of vaccine hesitancy， and major influencing factors. It aims to provide references for the development of scientific and effective vaccine education strategies， which can increase public knowledge and understanding of vaccines， enhance healthcare professional's willingness and behavior in recommending vaccines， improve public vaccine literacy， and reduce vaccine hesitancy. At the same time， the supervision and guidance of media discourse should be strengthened to enhance the protective role of non-NIP vaccines in immunization barriers.

ObjectiveTo preliminarily explore the mechanism of Shufeng Tongluo prescription （SFTLP） in inhibiting airway inflammation in asthma mice by affecting the expression levels of eotaxin in the serum， CC type chemokine receptor 3 （CCR3）， and extracellular signal-regulated kinase （ERK） phosphorylation in lung tissues. MethodSeventy C57BL/6 mice were randomly divided into a blank group， a model group， low-， medium-， and high-dose SFTLP groups （7.75， 15.5， 30 g·kg^-1）， a pertussis toxin （PTX） group， a CCR3 inhibitor （SB328437） group， a phosphoinositide 3-kinase （PI3K） inhibitor （LY294002） group， a p38 protein kinase antagonist inhibitor （SB203580） group， and an ERK inhibitor （PD98059） group. The asthma model was induced in mice by intraperitoneal injection of ovalbumin （OVA） and aluminum hydroxide ［Al（OH）₃］ combined with OVA atomization （0.2 mL for all）. After modeling， hematoxylin-eosin staining （HE staining） was used to observe the inflammatory infiltration of lung tissues in mice. Enzyme-linked immunosorbent assay （ELISA） was used to detect the serum levels of eotaxin ［CC chemokine ligand （CCL） 11 and CCL24） in each group. Western blot was used to detect the levels of ERK phosphorylation and CCR3 in lung tissues. ResultCompared with the blank group， the model group showed obvious bronchial constriction， lumen stenosis， damaged alveolar structure， massive inflammatory cell infiltration in lung tissues， mucous plug in the bronchus， edema in the submucosal tissues of the trachea， increased folds， increased serum levels of CCL11 and CCL24 （P<0.01）， and increased expression of CCR3 protein in lung tissues （P<0.05）. The ERK levels in lung tissues of the model group and the PTX group increased （P<0.05）. The level of p-ERK in lung tissues of the model group and the low-dose SFTLP group increased （P<0.05）. As revealed by pathological results， compared with the model group， the high-dose SFTLP group showed relieved lung lesions. The high-dose SFTLP group and the SB328437 group showed reduced CCL11 content （P<0.05）. The low- and high-dose SFTLP group， the PTX group， the SB203580 group， the PD98059 group， and the SB328437 group showed decreased CCR3 protein expression in lung tissues （P<0.05）. The high-dose SFTLP group and the PD98059 group showed reduced p-ERK level （P<0.05）. The PD98059 group showed reduced ERK level （P<0.05）. ConclusionSFTLP can inhibit airway inflammation in asthma， and the mechanism may be related to the inhibition of eosinophil activation by down-regulating CCR3 and CCL11 expression and ERK phosphorylation.

Multiple plant lineages have independently evolved sex chromosomes and variable kary-otypes to maintain their sessile lifestyles through constant biological innovation.Morus notabilis,a dioecious mulberry species,has the fewest chromosomes among Morus spp.,but the genetic basis of sex determination and karyotype evolution in this species has not been identified.In this study,three high-quality genome assemblies were generated for Morus spp.[including dioecious M.notabilis(male and female)and Morus yunnanensis(female)]with genome sizes of 301-329 Mb and were grouped into six pseudochromosomes.Using a combination of genomic approaches,we found that the putative ancestral karyotype of Morus species was close to 14 protochromosomes,and that sev-eral chromosome fusion events resulted in descending dysploidy(2n=2x=12).We also charac-terized a～6.2-Mb sex-determining region on chromosome 3.Four potential male-specific genes,a partially duplicated DNA helicase gene(named MSDH)and three Ty3_Gypsy long terminal repeat retrotransposons(named MSTG1/2/3),were identified in the Y-linked area and considered to be strong candidate genes for sex determination or differentiation.Population genomic analysis showed that Guangdong accessions in China were genetically similar to Japanese accessions of mul-berry.In addition,genomic areas containing selective sweeps that distinguish domesticated mul-berry from wild populations in terms of flowering and disease resistance were identified.Our study provides an important genetic resource for sex identification research and molecular breeding in mulberry.
