To investigate the association between sleep-related phenotypes and the risk of malignancy in pulmonary nodules, and to provide complementary evidence from a general population cohort and genetic analyses. This study comprised three parts. Part 1 was a cross-sectional study that consecutively enrolled patients with imaging-confirmed pulmonary nodules at the First Hospital of China Medical University from November 2024 to December 2025. Nine sleep domains were constructed using items from the Pittsburgh sleep quality index (PSQI), with domain severity coded on a 0-6 scale according to the frequency of occurrence. Benign or malignant status of pulmonary nodules was determined based on pathological results or clinical follow-up. Multivariable Logistic regression models with progressive adjustment were constructed. Stratified, interaction, and dose-response analyses (including categorical grouping and restricted cubic splines) were performed focusing on the insomnia symptom domain to explore the association between sleep-related phenotypes and the risk of malignant pulmonary nodules. Part 2 was a prospective cohort study using the China Health and Retirement Longitudinal Study (CHARLS) to investigate the association between sleep duration and incident lung cancer risk in the general population. Part 3 comprised genetic causality analyses, including two-sample Mendelian randomization (MR) and linkage disequilibrium score regression (LDSC), using data from the OpenGWAS database, to assess whether directionally consistent genetic association signals exist between sleep-related phenotypes and lung cancer risk. In the cross-sectional study, a total of 800 patients with pulmonary nodules were included, of whom 288 (36.0%) were in the malignant group. In the continuous-variable main model fully adjusted for baseline confounders, all nine sleep domains, imaging findings, and depression and anxiety status, the severity of the insomnia symptom domain showed a positive association signal with the risk of malignant pulmonary nodules (fully adjusted model: per 1-point increase, In patients with pulmonary nodules, an association signal exists between insomnia-related symptoms and the risk of malignancy, but the dose-response relationship remains unclear. The CHARLS cohort and genetic analyses provide supplementary directional clues for the above associations, albeit with limited statistical strength and result consistency. Definitive conclusions regarding the association between sleep phenotypes and the risk of malignant pulmonary nodules require further validation in prospective studies.

In vaccination,traditional vaccines are administered intramuscularly or subcutaneously,mainly inducing humoral immunity,with weak induction of mucosal immunity and insufficient protection against respiratory and gastrointestinal viruses.Current research has found that immuni-zation vaccines can effectively induce mucosal immunity through oral or nasal administration,but there is a lack of effective mucosal adjuvants,and there is an urgent need for the development of safe and effective new mucosal adjuvants.With the advancement of nano-adjuvant research,novel nanoparticles have attracted widespread attention due to their good mucosal adhesion,efficient an-tigen-loading ability,biocompatibility,and advantages in immune-enhancement,nano-size effect,tissue-targeting,and slow release of antigens,etc.,and are expected to be used as novel mucosal ad-juvants in the prevention and treatment of animal diseases.To date,significant progress has been made in research targeting mucosal adjuvants such as polymeric nanoparticles,inorganic nanoparti-cles,and liposomes.This paper reviews the application of nanomucosal adjuvants in animal vaccines and their mechanisms of action at home and abroad,and analyzes the physicochemical factors af-fecting the immune-enhancing effect of nanoparticle adjuvants,with a view to providing a reference for the development of novel mucosal adjuvants.

Pseudopleuronectes yokohamae is an important marine economic fish species in northern China and is vulnerable to various pathogens during the breeding process.To investigate the viru-lence of Edwardsiella tarda on Pseudopleuronectes yokohamae and elucidate the role of miRNAs in their interaction,we conducted pathological analyses on various tissues of Pseudopleuronectes yokohamae larvae pre-and post-infection with Edwardsiella tarda.Subsequently,Illumina high-throughput sequencing was employed to identify and functionally characterize differentially ex-pressed miRNAs in liver and kidney tissues.The results demonstrated that infection with Ed-wardsiella tarda led to ulceration,hemorrhaging,significant hepatomegaly,nephromegaly,and as-cites in the abdominal cavity.Histopathological examination revealed swollen hepatocytes with vac-uolization,minor blood cell infiltration,and enlarged renal corpuscles with signs of cellular lysis.miRNA sequencing analysis indicated that 24 miRNAs were significantly upregulated and 45 miR-NAs were significantly downregulated in the liver,while in the kidney,6 miRNAs were upregulat-ed and 58 were downregulated following infection.Functional enrichment analysis revealed signifi-cant enrichment of differentially expressed miRNAs in Toll and IMD signaling pathways,HIF-1 signaling pathway,Rap1 signaling pathway,MAPK signaling pathway,and Apelin signaling path-way.These findings suggest the involvement of these miRNAs in host metabolism,pathogen rec-ognition,and immune response in the interaction between Pseudopleuronectes yokohamae and Ed-wardsiella tarda.This research lays a foundation for elucidating the mechanisms underlying bacte-rial disease susceptibility and resistance in Pseudopleuronectes yokohamae.

The exploration and pilot studies of applying blockchain to drug supply chain show great potential in promoting information sharing, collaboration competence among the actors, regulatory efficiency, and etc. In the future, with the help of blockchain, the optimization of the entire supply chain for orphan drugs is expected to be realized. However, there is no such exploration in China at present. This paper systematically sorts out the whole process of supply chain for orphan drugs and the existing problems of the chain. The article concludes that at present, blockchain is mainly used in the " circulation" and " use" of the drug supply chain. It helps to improve the traceability of drugs, to cope with the problem of counterfeit drugs, to enable actors of the drug supply chain to form a collaborative network in optimizing resource allocation, and to improve the operation and supervision efficiency of the supply chain. In the future, the application faces challenges such as high costs in system conversion, lack of personnel awareness, and incomplete supporting systems. Based on the three dimensions of technology, practice, and research, this paper also looks into the future and suggests for the future use of blockchain in the supply chain of orphan drugs by constructing a practice model, the so called DI-GIVE (Digital, Intelligence, Government′s supervision, Innovation, Views of variety, Evaluation-based) hoping to innovate the supply chain of orphan drugs and to ensure the drug use for the patients with rare diseases in China.

Objective:To investigate the feasibility of thigh muscles segmentation in patients with Duchenne muscular dystrophy (DMD) using the TransUNet deep learning model on MRI.Methods:This was a cross-sectional study. From April 2023 to September 2024, the axial T 1WI imagings of 60 DMD patients, confirmed by genetic analysis at Northwest Women′s and Children′s Hospital, were enrolled in this retrospective study. Patients were divided into a training set ( n=48) and a test set ( n=12) at a ratio of 8∶2 using random sampling. Fat infiltration scores were assigned to 11 thigh muscles, including the rectus femoris, vastus lateralis, vastus intermedius, vastus medialis, sartorius, adductor longus, adductor magnus, gracilis, semimembranosus, semitendinosus, and biceps femoris long head. A total of 1 078 images were included (884 for training, 194 for testing).The 12 DMD patients in the test set were divided into groups G1 to G4, with 2, 4, 2, and 4 cases respectively, according to the total score of muscle fat infiltration from low to high. A TransUNet model was trained on the T 1WI to perform automatic segmentation of the 11 thigh muscles in both thighs. The segmentation performance of the TransUNet automatic segmentation model was evaluated using the Dice similarity coefficient (DSC), intersection over union (IoU), and average symmetric surface distance (ASSD), with the results of manual delineation by physicians as the gold standard. And one-way analysis of variance or the Kruskal-Wallis H test was used to compare the segmentation effects of the automatic segmentation model on the thigh muscles of children among G1 to G4. Results:The mean processing time for the automatic segmentation of all 11 muscles in both thighs per patient was (8.3±1.5) s. The DSC, IoU and ASSD in training set and in test set were 0.971±0.011, 0.948±0.019, 0.69 (0.55, 0.96) and 0.944±0.021, 0.900±0.038, 0.58 (0.55, 0.91), respectively. In the training set, the semitendinosus muscle achieved the best segmentation results (DSC 0.99, IoU 0.97, ASSD 0.52). In the test set, the sartorius muscle showed the best segmentation performance (DSC 0.96, IoU 0.93, ASSD 0.50). There were no statistically significant differences in the overall DSC, IoU, or ASSD of the automatic segmentation model across groups G1 to G4 ( P>0.05). Conclusions:The TransUNet automatic segmentation model can rapidly and accurately segment the bilateral thigh muscles in patients with DMD, and the segmentation performance demonstrated consistent among patients with different degrees of muscle fat infiltration.
