Objective To understand the epidemiological and genotypic characteristics of norovirus (NoV) in Jingzhou area，and to design primers and probes covering the variant genomes in the NoV gene library. Methods A total of 556 fecal samples were collected from suspected NoV patients from the First People's Hospital of Jingzhou from January 2022 to May 2023. The positive rate of NoV nucleic acid in fecal samples was detected by commercial kits. The differences in positive rates among different seasons and five age groups were statistically analyzed. Primers covering the NoV variant genome were designed to genotype some positive specimens. Results The detection rate of NoV nucleic acid in the tested samples was 30.04% (167/556). The detection rate in spring and winter was higher than that in summer and autumn (χ²=20.411，P<0.01). There were statistical differences in the positive rates among the five age groups of <1 year, 1-5 years, 6-10 years, 11-19 years, and >19 years (χ²=17.192，P<0.01), and the positive rate in young children (1~5 years old) was the highest (39.29%, 88/224). In addition, all the positive samples were NoV GII. Conclusion The epidemic situation of NoV is serious in winter and spring in Jingzhou area, with a high infection rate in young children (1-5 years old), and NoV GII is the main prevalent genotype. The primers designed in this study can be used for genotyping of NoV GI and GII.

In cases where a tracheal injury exceeds half the length of the adult trachea or one-third of the length of the child trachea, it becomes difficult to perform end-to-end anastomosis after tracheal resection due to excessive tension at the anastomosis site. In such cases, tracheal replacement therapy is required. Advances in tissue engineering technology have led to the development of tissue engineering tracheal substitutes, which have promising applications. Hydrogels, which are highly hydrated and possess a good three-dimensional network structure, biocompatibility, low immunogenicity, biodegradability, and modifiability, have had wide applications in the field of tissue engineering. This article provides a review of the characteristics, advantages, disadvantages, and effects of various hydrogels commonly used in tissue engineering trachea in recent years. Additionally, the article discusses and offers prospects for the future application of hydrogels in the field of tissue engineering trachea.

Objective: To explore the influencing factors and pathways of suicidal ideation among children and adolescents with severe autism spectrum disorder (ASD), so as to provide references for clarifying the impact intensity and pathways of various factors on suicidal ideation in the population. Methods: A cross sectional study was conducted from June 17, 2024, to January 12, 2025, involving 96 severely affected ASD children and adolescents aged 8-18 years from Tianjin. Participants were assessed using the Puberty Development Scale (PDS), Children s Alexithymia Measure (CAM), Strengths and Difficulties Questionnaire (SDQ), and Positive and Negative Suicide Ideation (PANSI). The random forest Boruta algorithm was employed to screen core variables, and a Bayesian network model was constructed to analyze the influencing factors of suicidal ideation in children and adolescents with severe ASD. Results: Through the screening using the Boruta algorithm, the SDQ scale score, conduct problems, hyperactivity, peer relationship problems and prosocial behavior were identified as the key predictors of suicidal ideation. A Bayesian network model was established with hyperactivity as the central mediating node. The impact of hyperactivity on suicidal ideation exhibited a non linear relationship: compared to the normal state (31.6%, 68.4%), the borderline state of hyperactivity was associated with a higher probability of low risk suicidal ideation (47.1%) and a lower probability of high risk suicidal ideation (52.9%). Suicidal ideation among children and adolescents with severe ASD was closely related to hyperactivity. In the state of hyperactivity, the abnormal peer relationship (95.2%) and the abnormal prosocial behavior (77.0%) were aggravated. Conclusions Suicide ideation among children and adolescents with severe ASD is strongly associated with hyperactivity traits. It is necessary to establish a prevention and control system centered on hyperactivity intervention to reduce this risk.

OBJECTIVE To explore the relationship between white matter damage and sleepiness,decreased sleep quality,and cognitive decline in patients with OSA.METHODS There were 55 confirmed cases of OSA diagnosed by polysomnography(PSG)from January 2018 to May 2023 were selected,with 29 non-OSA controls also diagnosed by PSG.DKI scanning and Epworth sleepiness scale(ESS),Pittsburgh sleep quality index(PSQI),and Montreal cognitive assessment(MoCA)scores were performed for all subjects.Differences in kurtosis fractional anisotropy(KFA)of various brain regions were compared between the two groups to identify differential brain regions,and pairwise correlations were analyzed between KFA reduction and apnea-hypopnea index(AHI),lowest oxygen saturation(LSaO2)and various scale scores in OSA patients.RESULTS The KFA values in right external capsule,bilateral corona radiata,bilateral superior longitudinal fasciculus,corpus callosum,posterior cingulate gyrus of OSA group were lower than control group(P<0.05).For the OSA group:The correlation between ESS scores and KFA values of right posterior corona radiata,left superior longitudinal fasciculus,body of corpus callosum,splenium of corpus callosum are all negative(r=-0.287,-0.286,-0.276,-0.449,P<0.05).The correlation between PSQI scores and KFA values of right posterior corona radiata,left posterior corona radiata,splenium of corpus callosum are all negative(r=-0.390,-0.274,-0.348,P<0.05).The correlation between MoCA scores and KFA values of right posterior corona radiata,right superior longitudinal fasciculus,left anterior corona radiata,left posterior corona radiata,left superior corona radiata,left superior longitudinal fasciculus,genu of corpus callosum,body of corpus callosum,are all positive(r=0.290,0.389,0.298,0.278,0.340,0.473,0.344,0.344,P<0.05).The correlation between visuospatial and executive function scores and AHI,LSaO2,ESS scores and KFA values of right posterior corona radiata,left superior corona radiata,left superior longitudinal fasciculus and splenium of corpus callosum are all significant(r=-0.350,0.470,-0.343,0.401,0.284,0.387,0.274,P<0.05).CONCLUSION Patients with OSA exhibit damage to the white matter in certain brain regions.The damage to the corpus callosum,posterior corona radiata,and superior longitudinal fasciculus has the greatest impact on patients'sleepiness,reduced sleep quality,and cognitive impairment.In particular,the impairment in visuospatial and executive function is closely associated with white matter damage in the corona radiata and superior longitudinal fasciculus.

Objective To analyze the current research application status and hotspots of nanoparticles in the treatment of non-small cell lung cancer (NSCLC) and predict the future development trend. Methods The Web of Science database was searched for literatures on nanoparticles use in the treatment of NSCLC from inception to November 2022. CiteSpace, VOSviewer and literature measurement analysis online platform (https://bibliometric.com/) were used for the visual analysis of the number of documents, source journals, authors, organizations, countries and keywords. Results A total of 742 English literatures were included. The results showed that the number of published literatures increased year by year from 2011 and reached the peak in 2020. Researches on nanoparticles and NSCLC treatment were mainly concentrated in China, the United States, India and Japan. China is a major research country in this field, but it lacked cooperation with other countries and related institutions. Among numerous research institutions, the Chinese Academy of Sciences was the authoritative and backbone force in this research field, with the number of published literatures ranking first and the research achievements outstanding. The keyword analysis found that "poly lactic-co-glycolic acid nanoparticles (PLGA NPs)" and "photothermal therapy" had become the latest breakout words since 2018. Moreover, the occurrence frequency of related keywords such as "drug delivery" increased significantly, indicating that the application of PLGA NPs in photothermal therapy might be the current research hotspot and future development trend of NSCLC treatment. Conclusion Currently, the domestic research on the treatment of nanoparticles and NSCLC is in a leading position in the world. The organic combination of nanoparticles with different materials and other NSCLC therapies is expected to improve the prognosis of NSCLC patients. In the future, attempts to develop nanoparticles with different sources and structures and combined with photothermal therapy for the treatment of NSCLC may become a research hotspot of nanoparticles in the treatment of NSCLC.

Rosai-Dorfman disease (RDD) is a benign self-limited disease characterized by lymphadenopathy and phagocytosis of lymphocytes by histiocytes. A case of intracranial-extracranial non communicating RDD was reported in this paper. The patient was admitted to Shiyan Taihe Hospital in May 2020 because of "the left top scalp tumor was found for 4 months, and the right lower limb was numb for more than half a month". The plain scan and enhanced scan of the patient′s head magnetic resonance imaging (MRI) showed that the disease focus of the left parietal bone was slightly uneven enhanced, its internal and external soft tissues were significantly enhanced, and the local internal and external soft tissues were significantly thickened irregularly, with the size of about 3.2 cm× 4.7 cm, and adjacent brain parenchyma was compressed. After resection of left top mass and intracranial mass, pathological results showed spindle cell proliferation with inflammatory reaction, and immunohistochemical staining results supported the diagnosis of RDD. The neurological function of the patient recovered to normal basically 7 months after operation, and no recurrence of the disease was found in the MRI examination of the head. The treatment effect was satisfactory.

Objective:To investigate the effect of centrosome protein 55 (CEP55) on the proliferation of bladder cancer cells and its related molecular mechanism.Methods:Western blot was used to detect the expression of CEP55 and H3K9me3 in normal bladder tissue cells (SV-HUC-1) and bladder cancer cells (T24) . The bladder cancer cells T24 were divided into experimental group and control group. The experimental group cells were transfected with siRNA-CEP55, and the control group cells were transfected with siRNA-MOCK. The expression levels of CEP55, H3K9 and H3K9me3 in each group of cells were detected by Western blot. The proliferation ability of each group of cells was detected by CCK8 assay.Results:Western blot assay showed that the expression of CEP55 and H3K9me3 in T24 cells was 0.83±0.15 and 1.01±0.19 respectively. The expressions of CEP55 and H3K9me3 in bladder epithelial SV-HUC-1 cells were 0.35±0.09 and 0.44±0.10 respectively. The expressions of CEP55 and H3K9me3 in bladder cancer cells were higher than those in normal bladder cells (all P<0.05) . siRNA-CEP55 successfully reduced the expression of T24 CEP55 in bladder cancer cells. The absorbance of T24 cells in the experimental group was 1.109±0.105, which was significantly lower than that in the control group (2.208±0.104) . Low expression of CEP55 reduced the proliferation ability of T24 cells ( P<0.05) . Western blot results showed that H3K9 was not significantly changed in T24 cells in the experimental group, and H3K9me3 expression decreased significantly ( P<0.05) . Conclusion:CEP55 can inhibit the proliferation of bladder cancer cells by reducing the trimethylation of H3K9.
