OBJECTIVES: To analyze the association of CHMP2B expression level of with clinicopathological characteristics and prognosis of clear cell renal cell carcinoma (CRCC) and the possible role of CHMP2B in tumorigenesis and progression of CRCC. METHODS: RNAseq data of CRCC were downloaded from the TCGA database for analysis of CHMP2B expression levels in tumor and adjacent tissues and their correlation with clinicopathological characteristics of the patients. Survival outcomes of the patients with high and low CHMP2B expressions were analyzed using the Kaplan-Meier model, and the COX risk regression model was used for identifying the prognostic factors of the patients. The correlation between CHMP2B expression and immune infiltration, its co-expressed genes, and the effect of CHMP2B gene mutations on immunotherapy responses, and its immunohistochemical expression in CRCC and normal tissues were analyzed. Clinical samples of CRCC were collected to examine CHMP2B expressions using RT-PCR, and cell experiment was carried out to test the effect of CHMP2B overexpression on biological behaviors of CRCC cells. RESULTS: CHMP2B was significantly under-expressed in renal cancer tissues, and its overexpression obviously inhibited the proliferation of CRCC cells in vitro. CHMP2B expression level was significantly correlated with age, gender, lymph node metastasis, and tumor stage, and the patients with low CHMP2B expression had poor survival outcomes. Enrichment and co-expression gene analyses suggested that CHMP2B was mainly involved in viral outgrowth, necrotic apoptosis, endocytosis, and immune-regulatory processes in kidney cancer. CONCLUSIONS CHMP2B is lowly expressed in renal cancer tissues to affect tumor progression and tumor immune processes, and may serve as a prognostic biomarker and therapeutic target for CRCC.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective To identify the measurement time,assessment tools,changing trends,factors in longitudinal studies on post stroke fatigue.Methods Web of Science,PubMed,CINAHL,Embase,CNKI,CBM,Wanfang,and VIP database were retrieved from inception until December 15,2024.Results A total of 41 papers were included.The measurement time points used with high frequency were 3,6,and 12 months after stroke.10 assessment tools were retrieved and the fatigue severity scale was most selected.The majority of the studies supported that the incidence of post stroke fatigue showed a decreasing trend within 6 months after stroke,an increasing trend from 6 to 12 months,and a decreasing or steady decreasing trend from 12 months.Post stroke fatigue is influenced by demographic,disease,physiologic,psychological,and coping factors.Conclusion The longitudinal studies on post stroke fatigue focused less than 1 year after stroke,but the recovery period is understudied and specific assessment tools need to be further explored.The trend of post stroke fatigue varies at different stages and exists heterogeneity.Future studies should be optimized to explore influence factors.

The aim of this study is to establish a rapid,efficient,and sensitive method for detecting the infectious laryngotracheitis virus(ILTV).The DNA of ILTV was extracted and used as a tem-plate to develop a recombinant enzyme-mediated isothermal amplification(RAA)fluorescence de-tection method for ILTV through optimization of conditions,sensitivity analysis,and repeatability assessment.Additionally,the nucleic acids of avian influenza virus(AIV),IBV,and Newcastle dis-ease virus(NDV)were detected to verify the specificity of this method.Finally,this method was applied to analyze 59 clinical samples collected from multiple large-scale chicken farms in Hebei Province,and the results were compared with those obtained from real-time fluorescence quantifi-cation(qPCR)and PCR methods according to national standards.The results showed that the RAA detection method established in this study had a reaction system of 25.0 μL buffer,2.1 μL primer,0.6 μL probe,5.0 μL magnesium acetate,and 5.0 μL template.The reaction temperature was 39 ℃ and the amplification time was within 20 minutes.The sensitivity of this method was 101 copies/μL,and the specificity detection was 100％.Testing of 59 clinical samples showed that 17 were detected positive by both RAA fluorescence and qPCR,and 12 were detected by PCR,and the detection rate of RAA(fluorescence)was consistent with real-time fluorescence quantification and qPCR,which was higher than that of the PCR assay.The research results indicate that the RAA fluorescence method has a short detection time,good specificity and sensitivity,and can be used for rapid detection of ILTV.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

In order to understand the difference and expression of genes in CEK cells before and af-ter baicalin interferes with IBV,further reveal and analyze the mechanism of baicalin interfering IBV replication in CEK cells in vitro.After IBV infected CEK cells for 2 h,9.75 mg/L baicalin liq-uid was added to interfere with CEK cells,which was recorded as the baicalin(H-IBV)group,and three replicate wells were set in the control group and the IBV(IBV)infection group.After 36 h culture,cell samples were collected and subject to transcriptome for sequencing.The results showed that there were 102 differentially expressed genes in H-IBV group compared with IBV in-fection group,among which 48 genes weresignificantly up-regulated and 54 genes were significantly down-regulated.Through functional annotation in GO and KEGG databases,it was found that dif-ferentially expressed genes were mainly annotated in biological processes such as cellular proces-ses,biological regulation,metabolism,and secondary pathways such as viral infectious diseases,signal transduction and interaction.Retinol metabolism pathway,phospholipid transfer to mem-brane,IL-27 mediated signaling pathway,MDA5/RIG-I and Toll-like receptor signaling pathway were significantly enriched in CEK cells,and the production of type Ⅰ interferon and interferon al-pha and the process of antiviral infection were also positively regulated.There were more differen-tial genes enriched in nucleic acid catalysis,immune system,and reaction,and interbiological reac-tion.Through the STRING network interaction map,it was found that most immune-related genes could form a 36-node interaction network centered on IRF7,TLR3 and STAT1.Therefore,com-pared with IBV group,the differentially expressed genes after baicalin treatment were mainly an-notated and enriched in the biological process,and the immune system and response were en-hanced,mainly through the positive regulation of IRF7 in the MDA5/RIG-I receptor signaling pathway and the inhibition of TLR3 signal transduction in the Toll-like receptor signaling path-way.Positive regulation of IL-27 mediated pathway and regulation of JAK-STAT signaling path-way were supplemented by activation of the expression of IRF7,TLR3,STAT1 and other related genes,and interaction with corresponding downstream proteins to promote the expression of IFN-α and regulatory cytokines,coupled with negative regulation of viral(defense)response and viral processes.Thus,baicalin interferes with IBV replication in CEK cells.

Objective:To analyze the prevalence and related factors of depression symptom among middle-aged and older adults belonging to Zhiguo ethnic minority groups,who experienced relative isolation prior to mod-emization and bypassed the transitional period associated with feudal monarchy in Yunnan Province.Methods:Using stratified cluster sampling,a total of 1 035 individuals from Zhiguo ethnic minority groups were investigated with the 9-item Patient Health Questionnaire(PHQ-9)to measure depression symptom scores(a total score≥5 was considered indicative of depression symptom).A self-administered questionnaire was utilized to investigate 24 cova-riates across five dimensions:sociodemographic,social-interpersonal network,mental health status,physical health status,and health behaviors.Results:Among the surveyed participants,231 individuals(22.32％)exhibited depres-sion symptoms.The logistic regression analysis showed that middle-aged and elderly people belonging to Zhiguo ethnic minority groups with occupations as laborers(OR=8.73),farmers(OR=7.34),and other professions(OR=7.13),those who reported feeling stressed or anxious in the last month(OR=5.43),those suffering from one(OR=2.81)or more chronic illnesses(OR=2.14),experiencing sleep problems(OR=3.74)/debilitating(OR=1.69)/mild-moderate pain(OR=2.23,4.37),and engaging in sedentary behavior(OR=2.27)were at higher risk for depressive symptoms.The risk of depressive symptoms was lower among middle-aged and elderly people be-longing to Zhiguo ethnic minority groups with higher social support scores(OR=0.96)and meaning in life scores(OR=0.96).Conclusion:The prevalence of depressive symptoms among middle-aged and elderly individuals of Zhiguo ethnic minorities is substantial,influenced by multiple factors.
