Traditional Chinese medicine （TCM） clinical trials face challenges such as low participant compliance， insufficient geographical coverage， and cost-effectiveness imbalances. Decentralized clinical trials （DCT）， enabled by digital technology for remote data collection and monitoring， offer a new direction for TCM clinical trial research. This article systematically reviews three novel clinical trial design models. Combining the holistic concept and indivi-dualized treatment characteristics of TCM， it analyzes the challenges currently faced in TCM DCT practice， including the digitization and standardization of TCM theory， data security， privacy protection and patient engagement difficu-lties， insufficient ethical review and regulatory system adaptation， inadequate personnel training， and a shortage of interdisciplinary talent. Addressing these challenges， the article proposes methodological recommendations for DCT implementation that align with the principles of TCM diagnosis and treatment. These recommendations include promoting the intelligentization and standardization of TCM practices， constructing a full-chain data security and privacy protection system， improving the ethical framework and clarifying regulatory responsibilities， and cultivating and building interdisciplinary talent and capabilities， which provide theoretical and technical references for establishing standardized DCT practices in TCM.

Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

Thymoma is a malignant tumor originating from thymus epithelial cells, with an incidence of 1.3-2.6 per million. Due to its low incidence, lack of cells and animal models, there are relatively few studies on thymoma, and its diagnosis and treatment progress is relatively slow. The update of 5th edition of WHO Classification of Thoracic Tumors in 2021 and the NCCN( National Comprehensive Cancer Network) Clinical Practice Guidelines in Oncology: Thymoma and Thymoma Cancer in 2024 put forward many new views and suggestions on the diagnosis and treatment strategy of thymoma. This article reviews the research and treatment of thymoma based on the latest research progress in recent years, aiming to improve the clinician's understanding of thymoma, provide reference for treatment, and promote the research of thymoma.

To perform the phylogenetic characterization of an isolated porcine rotavirus(PoRV)and investigate its pathogenicity in suckling mice and piglets.A G4P[23]genotype PoRV strain JSJR2023 was successfully isolated from the diarrheic piglet feces through propagation in MA104 cells.The viral proliferation kinetics were analyzed using TCID50 assays,followed by complete genome sequencing through Sanger sequencing platforms.Comprehensive genotyping and phylogenetic reconstruction were conducted using MEGA7.0 with maximum likelihood algorithms.Pathogenicity was assessed in the following animal models:5-day-old C57BL/6 mice and 3-day-old piglets.Multidimensional evaluation included clinical monitoring(diarrhea scoring,growth parameters),virological detection,and histopathological analysis of intestinal tissues.The virus strain JSJR2023 could replicate efficiently in MA104 cells,achieving peak titers of 107.5 TCID50/mL.Whole genome genotype analysis showed that the strain belonged to G4-P[23]-I5-R1-C1-M1-A8-N1-T1-E1-H1.Phylogenetic analysis indicated that the VP3 and NSP4 genes of JSJR2023 strain were most closedrelated to human species rotaviruses,suggesting genetic reassortment between human and porcine RV strains.The animal experiments in suckling mice showed that the JSJR2023 strain infection caused diarrhea symptoms,intestinal edema and congestion,and shedding of intestinal villus epithelial cells.The pathogenicity experiments in piglets showed that compared with the control group,the challenged group of pig-lets had severe diarrhea symptoms,accompanied by reduced appetite and listlessness.Post-mortem examination revealed that the intes-tines were significantly thinner,congested,and filled with yellow watery contents.The challenged piglets showed typical pathological changes such as thinning of the intestinal wall and shortening and shedding of intestinal villi.In conclusion,this study successfully iso-lated a human-porcine recombinant G4P[23]PoRV strain and established the infection models in suckling mice and piglets,providing important tools for investigating the pathogenic mechanism of PoRV,evaluating vaccines and developing antiviral drug.

Purpose To investigate the value of high frame rate contrast-enhanced ultrasound(H-CEUS)in the qualitative diagnosis of focal liver lesions(FLLs).Materials and Methods Seventy-two patients with FLLs who visited Sichuan Provincial People's Hospital from August 2021 to August 2022 were retrospectively enrolled in this study.All patients were diagnosed by conventional ultrasound,followed by contrast-enhanced ultrasound(CEUS)and H-CEUS.The diagnostic value of CEUS and H-CEUS in FLLs was evaluated by comparing the initial enhancement time,enhancement direction,vascular morphology,peak intensity and enhancement uniformity displayed by the two methods.Results Compared with CEUS,H-CEUS could more clearly show the direction of arterial phase enhancement,vascular morphology and uniformity after enhancement of the lesion.The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of CEUS and H-CEUS for the diagnosis of 72 FLLs were 87.10％,96.77％;85.37％,87.80％;86.11％,91.67％;81.82％,85.71％and 89.74％,97.30％,respectively.The area under the curve of CEUS and H-CEUS for the diagnosis of FLLs was 0.862 and 0.923,respectively.Conclusion Compared with CEUS,H-CEUS can more clearly show the characteristic manifestations of the arterial phase of lesions,providing richer and more reliable information for the qualitative diagnosis of FLLs.H-CEUS has a high diagnostic efficacy for FLLs.

Pulmonary arterial hypertension(PAH)is a complex pulmonary vascular disease characterized by pro-gressive elevation of mean pulmonary artery pressure resulted from the pathological feature of pulmonary vascular re-modeling.Without medical intervention,PAH can eventually lead to right heart failure and death of patients.Up to the present,there are few treatment options for PAH are still mainly function through pulmonary vasodilation.Although these treatments can alleviate symptoms,the prognosis remains poor.In recent years,breakthroughs have been made in understanding the pathogenesis of PAH,thus support the development of new treatment strategies tar-geting at dysregulation of signaling pathways in PAH.This review focuses on five critical pathways and the relevant drugs those entered phase Ⅱ clinical trials and discusses their therapeutic potential,so to provide a basis for future research on targeting therapies for PAH patients.

Objective: To investigate the effects of decabromodiphenyl ether (BDE-209) on the size of subcutaneous transplanted tumors, related genes and signaling pathways of cervical cancer in mice. Methods: Forty female C57BL/6 mice were subcutaneously inoculated with mouse cervical carcinoma U14 cells in the lateral axilla to establish a mouse subcutaneous transplanted tumor model. These mice were randomly divided into a high-dose group (500 mg/kg), a medium-dose group (100 mg/kg), a low-dose group (20 mg/kg) and a control group (corn oil), and were exposed to BDE-209 or corn oil by gavage. Subcutaneous transplanted tumor tissue was taken after 21 days of BDE-209 poisoning, and the differentially expressed genes in the subcutaneous transplanted tumors of cervical cancer among the four groups were analyzed by high-throughput transcriptome sequencing and were subjected to Gene Ontology (GO) annotations and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. Protein-protein interactions (PPI) were analyzed using the STRING database, and the mRNA expression of hub genes was determined by real-time fluorescence polymerase chain reaction. Results: Compared with the control group, low-dose group and medium-dose group, the mass of subcutaneous transplanted tumors in the high-dose group was decreased (all P<0.05). Transcriptome sequencing results showed that compared with the control group, 2 011 genes were up-regulated and 1 165 genes were down-regulated in the high-dose group; 960 genes were up-regulated and 357 genes were down-regulated in the medium-dose group; 537 genes were up-regulated and 262 genes were down-regulated in the low-dose group (all P<0.05). GO and KEGG analysis showed that the differentially expressed genes in the high-dose group were mainly involved in cell chemotaxis and NOD-like receptor signaling pathway; the differentially expressed genes in the medium-dose group were mainly involved in cell chemotaxis and cytokine-cytokine receptor interactions; and the differentially expressed genes in the medium-dose group were mainly involved in processing and presentation of antigens, and the signaling pathways of the complement and coagulation cascades. Compared with the control group, the mRNA expression of TLR2, MMP9, IL-6, Fos, and TNF was up-regulated in the high-dose group (all P<0.05). Conclusion High-dose BDE-209 may affect Toll-like receptors, NOD-like receptors, and other immune and inflammatory-related signaling pathways and cancer-related genes, leading to a decrease in the mass of subcutaneous transplanted cervical cancer tumors in mice.
