Objective: To analyze the relationship between 24 h movement behaviors and cognitive function in children and adolescents, as well as the isotemporal substitution benefits, in order to provide a basis for developing cognitive development intervention strategies among children and adolescents. Methods: Relevant studies were searched in the Web of Science, PubMed, Embase, EBSCO, and China National Knowledge Infrastructure databases from their inception to November 30, 2024. Systematic evaluation was performed after document screening, data extraction and quality assessment. Results: A total of 24 highquality studies were included, comprising 35 295 children and adolescents aged 3-18 years. Adhering to the 24 h activity guidelines was associated with better cognitive performance (19 studies). Additionally, substituting 5-30 minutes per day of moderate to vigorous physical activity (MVPA) or sleep (SLP) for sedentary behavior (SB) or light physical activity (LPA) were associated with improvements in cognitive function (7 studies). There were inconsistencies in the effects of different types of SB (learning or entertainment) on cognitive function. Conclusions Adherence to the 24 h activity guidelines supports cognitive development in children and adolescents, with MVPA and SLP as key intervention targets. Increasing the proportion of MVPA, ensuring adequate SLP, and limiting recreational SB and screen time might be helpful to enhance the combined benefits of these three behaviors.

BACKGROUND: Currently, lung cancer is one of the malignant tumors with a high morbidity and mortality all over the world. However, the exact mechanisms underlying lung cancer progression remain unclear. The tumor necrosis factor receptor associated factor (TRAF) family members are cytoplasmic adaptor proteins, which function as both adaptor proteins and ubiquitin ligases to regulate diverse receptor signalings, leading to the activation of nuclear factor kappa-B (NF-κB), mitogen-activated protein kinase (MAPK) and interferon regulatory factor (IRF) signaling. The aim of this study was to investigate the expression of TRAFs in different tissues and cancer types, as well as its mRNA expression, protein expression, prognostic significance and functional enrichment analysis in non-small cell lung cancer (NSCLC), in order to provide new strategies for the diagnosis and treatment of NSCLC. METHODS: RNA sequencing data from the The Genotype-Tissue Expression database was used to analyze the expression patterns of TRAF family members in different human tissues. RNA sequencing data from the Cancer Cell Line Encyclopedia database was used to analyze the expression patterns of TRAF family members in different types of cancer cell lines. RNA sequencing data from the The Cancer Genome Atlas (TCGA) database was used to analyze the mRNA levels of TRAF family members across different types of human cancers. Immunohistochemistry (IHC) analyses from HPA database were used to analyze the TRAF protein levels in NSCLC [lung adenocarcinoma (LUAD) and lung squamous carcinoma (LUSC)]. Overall survival analysis was performed by Log-rank test using original data from Kaplan-Meier Plotter database to evaluate the correlation between TRAF expressions and prognosis. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed on the TRAF family-related genes using RNA sequencing data from the TCGA database for NSCLC. The correlation between the expression levels of TRAF family members and the tumor immune microenvironment was analyzed using the ESTIMATE algorithm based on RNA sequencing data from the TCGA database. RESULTS: The TRAF family members exhibited significant tissue-specific expression heterogeneity. TRAF2, TRAF3, TRAF6 and TRAF7 were widely expressed in most tissues, while the expressions of TRAF1, TRAF4 and TRAF5 were restricted to specific tissues. The expressions of TRAF family members were highly specific among different types of cancer cell lines. In mRNA database of LUAD and LUSC, the expressions of TRAF2, TRAF4, TRAF5 and TRAF7 were significantly upregulated; while TRAF6 did the opposite; moveover, TRAF1 and TRAF3 only displayed a significant upregulation in LUAD and LUSC, respectively. Except for TRAF3, TRAF4 and TRAF7, other TRAF proteins displayed an obviously deeper IHC staining in LUAD and LUSC tissues compared with normal tissues. Additionally, patients with higher expression levels of TRAF2, TRAF4 and TRAF7 had shorter overall survival; while patients with higher expression levels of TRAF3, TRAF5 and TRAF6 had significantly longer overall survival; however, no significant difference had been observed between TRAF1 expression and the overall survival. TRAF family members differentially regulated multiple pathways, including NF-κB, immune response, cell adhesion and RNA splicing. The expression levels of TRAF family members were closely associated with immune cell infiltration and stromal cell content in the tumor immune microenvironment, with varying positive and negative correlations among different members. CONCLUSIONS TRAF family members exhibit highly specific expression differences across different tissues and cancer types. Most TRAF proteins exhibit upregulation at both mRNA and protein levels in NSCLC, whereas, only upregulated expressions of TRAF2, TRAF4 and TRAF7 predict worse prognosis. The TRAF family members regulate processes such as inflammation, immunity, adhesion and splicing, and influence the tumor immune microenvironment.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective:To compare the prognosis of patients with hepatolithiasis-associated intrahepatic cholangiocarcinoma (ICC) and hepatitis B virus (HBV)-associated ICC after radical resection.Methods:The clinicopathological and survival data of 69 patients with ICC undergoing radical resection in the Department of Hepatobiliary and Pancreatic Surgery, Lihuili Hospital Affiliated to Ningbo University from January 2012 to February 2024 were retrospectively analyzed, including 40 males and 29 females, aged (62.9±10.2) years. Patients were divided into the stone group ( n=40, with hepatolithiasis) and HBV group ( n=29, with HBV). Kaplan-Meier method was used for survival analysis, and log-rank test was used for survival rate comparison. Cox proportional hazard regression model was used for multivariate analysis to analyze the effect of hepatolithiasis and HBV on the prognosis. Results:The median overall survival of ICC patients in the stone group was 16 months, and that in the HBV group was 27 months. The 1-, 3-, and 5-year cumulative survivals of the stone group were 56.6%, 23.2%, and 10.3%, respectively, which were lower than those of the HBV group (72.0%, 50.7%, and 43.4%, respectively, χ2=5.95, P=0.015). The median recurrence-free survivals (RFS) of the stone group and the HBV group were 12 months and 23 months, respectively. The 1-year and 3-year RFS of the stone group were 49.2% and 18.1%, which were lower than those of the HBV group (65.0% and 39.8%, respectively, χ2=3.94, P=0.047). Univariate analysis showed that hepatolithiasis was assciated with prognosis ( χ2=5.95, P=0.015). Multivariate Cox regression analysis showed that hepatolithiasis and hepatitis B virus infection had no effect on the prognosis of ICC patients after surgery (all P>0.05). Conclusion:Compared to HBV infection, ICC patients with hepatolithiasis have a worse prognosis. Hepatolithiasis and HBV infection have no effect on the prognosis of ICC after radical resection.

Objective To explore the predictive value of CT radiomics and morphological features for the prognosis and survival in non-small cell lung cancer(NSCLC)patients.Methods The clinic data of 300 NSCLC patients(300 lesions)were downloaded from the Cancer Imaging Archive,with 210 randomly selected as the training set and 90 as the test set.According to the prognosis and survival,the patients were divided into two groups with survival period≤3 and＞3 years.3D Slicer software was used to delineate the regions of interest layer by layer in CT images,and the radiomics features were extracted from each region of interest.Both t-test and least absolute shrinkage and selection operator were utilized for radiomics feature screening.Three types of prediction models,namely radiomics model,morphological model and combined model,were constructed with Logistic regression,whose performances were evaluated using the receiver operating characteristic(ROC)curve.Results The differences in radiomics labels and mediastinal lymph node metastasis between the training set and the test set were statistically significant.For radiomics model,morphological model and combined model,the area under the ROC curve was 0.784(95%CI:0.722-0.847),0.734(95%CI:0.664-0.804)and 0.748(95%CI:0.680-0.815)in the training set,and 0.737(95%CI:0.630-0.844),0.665(95%CI:0.554-0.777)and 0.687(95%CI:0.578-0.797)in the test set,which demonstrated that radiomics model had the best diagnostic performance.Conclusion The CT radiomics model can effectively predict the prognosis and survival in NSCLC patients.

Objective To summarize the liver biopsy and clinical features of patients with liver injury of unknown origin,and to investigate the value of ultrasound-guided percutaneous liver biopsy in the diagnosis of liver injury of unknown origin.Methods A retrospective analysis was performed for the clinical data and ultrasound-guided percutaneous liver biopsy results of 94 patients with liver injury of unknown origin who were admitted to Zhongshan Hospital,Xiamen University,from January 2018 to February 2023.According to the proportion of the patients with different final diagnoses,the patients were divided into autoimmune liver disease(AILD)group,metabolic associated fatty liver disease(MAFLD)group,drug-induced liver injury(DILI)group,alcoholic liver disease(ALD)group,and unknown group.An analysis of variance was used for comparison of normally distributed continuous data between multiple groups,and the Bonferroni analysis or the Dunnett'T3 test was used for further comparison between two groups;the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups;the Fisher's exact test was used for comparison of categorical data between multiple groups.Results All 94 patients with liver injury of unknown origin underwent ultrasound-guided percutaneous liver biopsy after admission,among whom 90 patients(95.7%)had a confirmed diagnosis based on liver biopsy and clinical features.There were 43 patients(45.7%)with AILD,21(22.3%)with MAFLD,15(16.0%)with DILI,6(6.4%)with ALD,1(1.1%)with AILD and MAFLD,1(1.1%)with hemochromatosis,1(1.1%)with Budd-Chiari syndrome,1(1.1%)with congenital hepatic fibrosis,and 1(1.1%)with idiopathic portal hypertension,while 4 patients(4.3%)still had an unknown etiology after liver biopsy.There were significant differences between the patients with top five diagnoses in age(F=4.457,P<0.05),body mass index(BMI)(F=3.245,P<0.05),aspartate aminotransferase(AST)(H=11.128,P<0.05),gamma-glutamyl transpeptidase(GGT)(H=24.789,P<0.05),alkaline phosphatase(ALP)(H=26.013,P<0.05),IgG(H=19.099,P<0.05),IgM(H=21.263,P<0.05),AMA-M2 positive rate(P<0.05),and ANA positive rate(P<0.05).Compared with the MAFLD group,the AILD group had significantly higher age,AST,GGT,and ALP and a significantly lower BMI;compared with the MAFLD group and the DILI group,the AILD group had significant increases in IgG and IgM;the AILD group had significant increases in the positive rates of AMA-M2 and ANA compared with the other four groups.Conclusion AILD,MAFLD,and DILI are the most common causes in patients with liver injury of unknown origin.Ultrasound-guided percutaneous liver biopsy plays an important role in determining the cause of liver injury of unknown origin,but it is still needed to make a comprehensive analysis based on clinical history,different types of liver injury,laboratory markers,and imaging data.

Objective To systematically evaluate the effect of speech and language therapies and educational interventions on chil-dren with intellectual and developmental disabilities(IDD). Methods A systematic review was conducted by searching relevant literature in PubMed,PsycINFO,ERIC,Cochrane Library and Web of Science databases,ranging from January,2018 to May,2024. Results A total of eight English articles were included,from six countries including the United States,France,Italy,Nor-way,Poland and New Zealand,involving 610 children with IDD,from journals about speech language pathology,Down syndrome research and speech language hearing research.The publication time was mainly from 2018 to 2023.The age of the subjects was two to twelve years,and the main health conditions included intellectual dis-ability,autism and Down syndrome.The intervention methods included routine speech therapy(individualized therapy and group therapy),augmentative and alternative communication(device-assisted and sign language and picture cards),family-involved language training programs(parent training and family interaction),computer-as-sisted language learning(language learning software and telehealth),and play-based interventions(interactive games and structured games);15 to 150 minutes a time,one to ten times a week,for ten to 144 weeks.The out-comes were reflected in five aspects:increasing the vocabulary in speaking;improving the language comprehen-sion,symbol recognition and vocabulary comprehension;improving both expressive and receptive language skills;improving participation in game diversity and game participation levels,communication,social interaction and interaction skills;and improving overall language and non-verbal communication skills. Conclusion Combining a variety of methods,such as individualized therapy,family participation,technologic assistance and interactive games,speech and language therapies and education are effective on spoken language production,language comprehension,speech production,social interaction and communication skills for children with IDD.

Objective To investigate the cause of a suspected outbreak of carbapenem-resistant Klebsiella pneumoniae infection(CRKP)in the neurological ICU,to find out the reason for infection and the way of transmission to provide evidence for the prevention and control of nosocomial infection.Methods Four patients with CRKP infection in the department of neurological ICU of a hospital from Au-gust 4 to August 20,2020 were investigated epidemiologically and environmental hygiene monitoring of the ward was carried out.Compre-hensive measures were taken to control the outbreak.Results All four CRKP infection cases were hospital-acquired,and the isolated strains showed consistent drug susceptibility test results,indicating they were the same clone.Environmental hygiene monitoring revealed the presence of the same clone in samples from patient bedside items,suction devices,oxygen therapy equipment,and personal belongings of healthcare workers.After implementing comprehensive corrective measures,no new cases of CRKP infection occurred,and subsequent surface sampling did not isolate any CRKP strains.Conclusion Environmental surface contamination in the neurointensive care unit and inadequate disinfection procedures were likely the main causes of the suspected outbreak of CRKP infection.Prompt identification of the outbreak,activation of emergency response plans,and implementation of corrective measures are crucial for controlling the outbreak of multidrug-resistant bacterial infections in hospitals.After adopting comprehensive measures,there were no new CRKP infection cases.

As an important complementary form of decoction pieces of traditional Chinese medicine（TCM）， TCM dispensing granules has the advantages of being free of decoction， easy to take， easy to carry and easy to be dispensed， which greatly improves the capacity of emergency services of TCM and is more in line with the needs of modern society. With the end of the pilot project of TCM dispensing granules， the market has been fully liberalized， the competition has been intensified， and it is in the transition period of switching between the new standard and the old one， and there are some problems such as the shortage of varieties， the change of specifications and the difference of quality， and the production enterprises are facing new opportunities and challenges. Based on this， the authors intend to systematically sort out the policies and regulations， enterprise layout and standard formulation since the pilot of TCM dispensing granules. In view of the problems in the post-pilot stage and from the perspective of survival and development of enterprises， it is suggested that enterprises should establish a quality control system for the whole industry chain of TCM dispensing granules to reduce process costs and increase enterprise competitiveness， further increase the investment in scientific research， overcome the key technical problems of difficult varieties， actively and orderly promote the research of national standards， in order to ensure the integrity of clinical formula varieties， and establish and improve the efficacy evaluation mechanism of TCM dispensing granules， build a consistency evaluation system between TCM dispensing granules and decoction pieces. Government departments should strengthen the guidance， fully mobilize the enthusiasm of scientific research institutions， enterprises and hospitals， and explore the establishment of "government-industry-study-research-application" mode to promote the development of TCM dispensing granule industry.

Via an insufficient coat protein complex I (COPI) retrieval signal, the majority of SARS-CoV-2 spike (S) is resident in host early secretory organelles and a tiny amount is leaked out in cell surface. Only surface-exposed S can be recognized by B cell receptor (BCR) or anti-S therapeutic monoclonal antibodies (mAbs) that is the trigger step for B cell activation after S mRNA vaccination or infected cell clearance by S mAbs. Now, a drug strategy to promote S host surface exposure is absent. Here, we first combined structural and biochemical analysis to characterize S COPI sorting signals. A potent S COPI sorting inhibitor was then invented, evidently capable of promoting S surface exposure and facilitating infected cell clearance by S antibody-dependent cellular cytotoxicity (ADCC). Importantly, with the inhibitor as a probe, we revealed Omicron BA.1 S is less cell surface exposed than prototypes because of a constellation of S folding mutations, possibly corresponding to its ER chaperone association. Our findings not only suggest COPI is a druggable target against COVID-19, but also highlight SARS-CoV-2 evolution mechanism driven by S folding and trafficking mutations.
