ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

Objective To study the dynamic regulatory role of early growth response 4(EGR4)in mouse neurodevelopment.Methods Data on single-cell chromatin accessibility(single-cell assay for transposase-accessible chromatin by sequencing,scATAC-seq)and transcriptome(single-cell RNA sequencing,scRNA-seq)from seven key stages spanning from the embryonic period to adulthood was collected and analyzed.The transcription factor binding site network was inferred,a quantitative analysis from a temporal perspective was conducted,its functional modules were parsed,and the results were visualized.Results egr4 was significantly highly expressed from the late embryonic stage to adulthood,and specifically activated during the maturation of inhibitory neurons[parvalbumin(PV)and somatostatin(SST)subtypes].Moreover,its transcription was not directly regulated by changes in chromatin accessibility.Temporal network analysis indicated that EGR4 became a regulatory hub in the late embryonic stage and drove neuron differentiation and subtype specification.Functional enrichment analysis showed that EGR4 regulated the"cell differentiation"pathway through dynamic interacting factors,and there were subtype-specific interaction modules in PV/SST neurons respectively.Conclusion EGR4 can participate in the late-stage maturation of cortical neurons through a stage-specific regulatory network.This study provides a new perspective on mechanisms underlying the temporal logic of neural development.

Objective To establish a prognostic model that predicts the survival and prognosis of gastric adenocarcinoma patients by studying the LncRNAs related to iron death in gastric cancer cells,thereby providing a theoretical basis for the development of their biomarkers and therapeutic targets.Methods The transcript sequencing data of gastric adenocarcinoma patients in the TCGA database were analyzed and intersected with iron death-related genes,which were screened for iron death-related LncRNAs by co-expression and differential analysis methods.One-way and multifactorial Cox regression analyses were used to screen out the prognostic-related LncRNAs in gastric adenocarcinoma patients,so as to establish the prognostic scoring models.On this basis,risk values were calculated for each sample,and the reliability of the model was fully verified.According to the model results,differences in the immune infiltration and immune response between the high-and low-risk groups were analyzed.Results Tumor tissues were screened for 503 LncRNAs(431 up-regulated and 72 down-regulated)associated with iron death compared to the normal tissues;univariate Cox regression analysis yielded 33 LncRNAs that could be used as the independent risk factors,whereas multivariate Cox regression analysis constructed a predictive model consisting of 17 LncRNAs.Survival curves indicated that patients with the high risk had the significantly lower survival rates than those with the low risk(P<0.001).Unifactorial and multifactorial independent prognostic analyses showed that age,stage,and risk value were independent risk factors for patients;Time-dependent ROC curves suggested that the predicted AUC values of the model's 1-,2-,and 3-year survival rates were 0.751,0.799,and 0.779 respectively,proving that the model was reliable and stable.There were significant differences in multiple immune activation responses,the degree of immune cell infiltration,and the expression levels of immune check points between the high-and low-risk groups.Conclusion The established prognostic prediction model based on iron death-related lncRNAs for gastric adenocarcinoma patients can better assess the prognosis of patients,and the lncRNAs included in the model have the feasibility of being developed into biomarkers and therapeutic targets.

Objective: To investigate the molecular mechanism of NOD-like receptor(NLR) signaling pathway induced cellular focal death in mouse kidney tissues under plateau hypoxia based on transcriptomic sequencing technology. Methods: Animal models were constructed in high-altitude kidney test group(HKT group) and plain kidney control group(PKC group),and C57/BL6 mice were bred at an altitude of 4 200 m and 400 m,respectively.Kidney tissues were aseptically taken out after 30 d and used for observation of renal histopathological changes and transcriptomics sequencing,respectively,and then differentially expressed genes(DEGs) were enriched by KEGG and GO analysis.Key gene and protein expression levels were verified by reverse transcription quantitative polymerase chain reaction(RT-qPCR) and Western blot analysis. Results: Hematoxylin-eosin(HE) staining showed that the renal tubules of HKT mice were disorganized,and the tubular epithelial cells were edematous with inflammatory cell aggregation.Transcriptomics sequencing analysis revealed that a total of 3 007 DEGs were identified in the HKT group,and KEGG analysis showed that DEGs were significantly enriched in the NLR signaling pathway.The mRNA expression of the key differentially expressed genes,CASP1,CASP11,GSDMD,IFI16,NAIP5,IRF9,and the downstream inflammatory factors,IL-1β and IL-18,was upregulated,and protein expression of CASP1,CASP11,and GSDMD was up-regulated. Conclusion The plateau hypoxic environment induces cellular pyroptosis by regulating the expression of NLR signaling pathway and releases downstream inflammatory factors to cause inflammatory responses.

Objective:To construct a VP8-mRNA vaccine using human rotavirus spike protein VP8 domain as the immunogen and analyze its immunogenicity in mice.Methods:The VP8-mRNA sequence was designed, optimized, and synthesized. The VP8 gene of rotavirus G1P[8] type was used to construct the plasmid pUC57-VP8-Kan-SapⅠ, which was then sequenced. The plasmid confirmed by sequencing was subjected to large-scale amplification and extraction, followed by linearization, in vitro transcription, and capping. The purified capped products were encapsulated with lipid nanoparticles using a microfluidic control apparatus. The encapsulated VP8-mRNA vaccine was administered intramuscularly to mice at 10, 15, and 20 μg. Serum samples were collected for antibody detection by ELISA. Cellular immune responses were detected by flow cytometry and ELISPOT. Statistical analysis was performed using one-way or two-way analysis of variance and Tukey-Kramer test. Results:The encapsulated VP8-mRNA vaccine was rounded and spherical, with a particle size of about 100 nm, a polymer dispersion index of 0.088, and an encapsulation rate of 92.3%. Two doses of VP8-mRNA vaccine immunization could induce a good immune response in mice. The level of IgG antibody induced after immunization in the 15 μg group was comparable to that of the 20 μg group, and there was no statistical difference ( P>0.05), but the antibody levels in the two groups were significantly higher than that in the 10 μg group ( P<0.000 1). VP8-mRNA vaccine could induce neutralizing antibodies against rotavirus G1 and G9 types. The highest level of neutralizing antibodies against rotavirus type G1 was observed in the 15 μg group, which was significantly higher than that in the 10 μg group ( P<0.05). All immunization groups exhibited good neutralizing ability against rotavirus G9 type. The results of ELISPOT showed that lymphocytes from mice in each vaccine group were able to secrete IFN-γ when stimulated with VP8 peptide. Flow cytometry showed that the proportions of CD8 + T cell subsets in the vaccine groups were higher than that in the control group. Conclusion:The VP8-mRNA vaccine has good immunogenicity in mice and can induce good humoral and T-cell immune responses.

Objective:To investigate the clinicopathological characteristics, diagnosis, origin, and prognosis of primary ovarian mesonephric-like adenocarcinoma.Methods:A total of 17 cases of primary ovarian mesonephric-like adenocarcinoma diagnosed at the Obstetrics and Gynecology Hospital of Fudan University and Jiaxing Maternal and Child Health Care Hospital between January 2018 and September 2024 were included in this study. Histopathological sections were retrospectively reviewed, and clinicopathological data were systematically analyzed. Immunohistochemical analysis, molecular profiling, and clinical follow-up were performed to further characterize the cases.Results:The patients′ age was (57.1±9.3) years. Tumor involvement included 1 bilateral case, 9 left-sided cases, and 7 right-sided cases. Nine cases originated from endometrioid cysts, and 8 cases exhibited coexisting tumor components of other types. Gross examination revealed gray-yellow solid masses or solid components within cysts. Microscopically, the tumors displayed diverse architectural patterns, including papillary, glandular, cystic, tubular, and solid structures, with eosinophilic secretions within glandular lumens and mild to moderate nuclear atypia. Immunohistochemically, the tumors showed variable expression of TTF1, GATA3, CD10, and Calretinin. ER and PR were focally positive in only 2 cases, while others were negative. All cases demonstrated intact DNA mismatch repair proteins expression and wild-type p53 staining patterns. Molecular analysis performed in 10 cases identified pathogenic KRAS mutations in all tested samples. During a follow-up period of 1 to 75 months, 5 cases had recurrence, 1 patient remained alive with disease, and no disease-related death was reported.Conclusions:Ovarian mesonephric-like adenocarcinoma is an aggressive malignancy with a high potential for early recurrence and metastasis. Its frequent association with endometriosis and coexistence with other Müllerian tumors suggest a potential Müllerian origin. The tumor′s diverse morphological spectrum and common admixture with other tumor types often pose diagnostic challenges, making it difficult to distinguish from other gynecological malignancies. Therefore, accurate diagnosis of ovarian mesonephric-like adenocarcinoma is crucial for appropriate clinical management and prognostication.

Objective This study aimed to investigate the tumorigenic properties of MMTV-PyMT breast cancer transgenic mice at different ages(in weeks)and the changes in the composition of immune cells in the tumor microenvironment.Methods Eight groups of 4,6,8,10,12,14,16 and 18 weeks of age MMTV-PyMT female mice(FVB mice as the background)and one group of 8 weeks of FVB female mice were prepared for routine blood testing,the pathological changes of the mammary gland and lung metastases were observed by histopathological sections,and the immune cells in blood,spleen,and tumor were analyzed by flow cytometry.Results MMTV-PyMT mice showed adenular ductal lesions at 4～6 weeks of age;the ductal portion expanded to the growth boundary at 8～9 weeks of age,and then gradually broke through the glandular boundary to form early breast cancer at 8～12 weeks of age,and advanced breast cancer at 10～14 weeks of age.At 12 weeks of age,metastases were visible in the lungs of some mice,and at 14 weeks of age,the number of metastases in the lungs increased significantly.As the age of the mice increased,the number of white blood cells,neutrophils,and platelets in their blood increased gradually,while the lymphocytes and erythrocytes showed a gradual downward trend.Flow cytometry showed that with the increase in age,the proportion of T cells in the spleen and tumor gradually decreased,the MDSCs in the blood,spleen,and tumor gradually increased,and the NK cells in the tumor also gradually increased.Conclusions This study analyzed routine blood tests,pathology,and immune cells in the tissues of MMTV-PyMT mouse models of different weeks of age,providing a novel perspective on the dynamic alterations of the tumor immune microenvironment during the malignant progression of breast cancer.
