Objective: To investigate the relationship between relative grip strength and hyperuricemia (HUA) levels in university freshmen, and to explore the potential value of muscle function indicators in HUA prevention among young populations, so as to provide new scientific evidences for HUA control in the demographic. Methods: Utilizing health examination data from 1 744 freshmen enrolled in a Shaanxi Province university in September 2024, absolute grip strength was measured using CAMRY electronic dynamometers, with relative grip strength subsequently calculated. Spearman correlation analysis was employed to examine relationships between student characteristics and relative grip strength, and binary Logistic regression models assessed the association strength between relative grip strength and HUA. Results: The overall HUA detection rate among freshmen was 29.8%, with significant gender differences (male:43.1%; female:24.0%; χ 2=64.62, P <0.01). Correlation analysis revealed significant associations between relative grip strength, body weight, height, body mass index (BMI) and HUA in both genders (boys: r =-0.27, 0.54, 0.11 , 0.53; girls: r =-0.18, 0.33, 0.08, 0.33, all P <0.05). Binary Logistic regression demonstrated that each standard deviation increase in relative grip strength reduced HUA risk by 77% in males ( OR=0.23, 95%CI =0.14-0.37) and 80% in females ( OR=0.20, 95%CI =0.11-0.36) (both P <0.01). Conclusions Relative grip strength represents a significant factor associated with HUA in university students. Incorporating muscle strength training into HUA prevention programs and establishing muscle function based HUA risk warning systems should be considered.

Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

Objective To explore the best neoadjuvant treatment strategy for esophageal cancer and provide a theoretical basis for clinical formulation of neoadjuvant treatment plan. Methods PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang, and VIP were searched from inception to May 2022. Two researchers independently performed literature screening and data extraction. The quality of the studies was evaluated by the Cochrane risk of bias tool, and data analysis was performed in RStudio environment using R3.6.3 software. Results A total of 24 studies were included, covering 5 286 patients treated with surgery alone, neoadjuvant chemotherapy (NCT), neoadjuvant radiotherapy (NRT), or neoadjuvant chemoradiotherapy (NCRT) followed by combined surgical treatment. The risk of bias of the studies was low. The results of the network meta-analysis showed that combined surgical treatments after NCRT [HR=0.77, 95%CI (0.70, 0.85)] and NCT [HR=0.89, 95%CI (0.81, 0.98)] were effective methods to improve patients' overall survival (OS) compared with surgery alone. In addition, NCRT could significantly reduce the incidence of local recurrence [OR=0.43, 95%CI (0.30, 0.58)] and distant metastasis [OR=0.71, 95%CI (0.52, 0.93)] in patients with esophageal cancer. However, NCRT [RR=1.30, 95%CI (0.77, 2.20)] increased the mortality rate of patients at 30 d after surgery. Conclusion The available evidence suggests that NCRT combined with surgery is the best option for treating patients with resectable esophageal cancer, but this treatment carries the risk of increased 30 d postoperative mortality. Future studies should focus on optimizing the NCRT regimen with the aim of improving patients’ OS while effectively reducing postoperative mortality. In addition, more high-quality randomized controlled trials are needed to support the results of the study.

Immune checkpoint inhibitors(ICIs)are an emerging tumor treatment approach following traditional surgery,chemoradiotherapy and targeted therapy.They have proven to be effective in a variety of cancers.However,they may induce immune-related adverse events(irAEs)during treatment,which may affect patients'quality of life and lead to treatment interruption or cessation.The key to preventing irAEs is early evaluation and identification of medical staff.Therefore,this article reviews the clinical manifestations and influencing factors of irAEs to help the early identification of high-risk groups and provide reference for clinical nursing work.

Objective:To establish Chinese grading standards for elderly disability and dementia, in accordance with the International Classification of Functioning, Disability and Health(ICF)items, and to develop visual assessment tools that can be easily understood by patients, family members, and health workers.The aim is to verify the reliability and validity of these tools.Methods:In this study, we established five categories of elderly disability classification, along with corresponding ICF items and visual evaluation tools.The appropriateness and compatibility of the tools were assessed using questionnaires, which included illustrations, GIF dynamic pictures, and ICF items.Correlation analysis was conducted to screen the items, and the validity of the visual evaluation tools was determined through a picture-text matching validity test.Reliability was evaluated using internal consistency or test-retest reliability, and validity was assessed through content validity.Results:Each grade of disability was initially divided into five levels.However, after expert consultations and classification revision, each level was ultimately simplified into four levels with clearer descriptions.The Pearson correlation coefficients between all items and the total scores of each part were found to exceed 0.3, and the difference was statistically significant(all P<0.05).The average and mode of the illustrations and GIF dynamic pictures, when matched with related descriptions, were both above 3, with consistency rates surpassing 50%.Statistical differences were observed in eight items between the two visual assessment tools.The Cronbach's α coefficients, which reflect internal consistency, were all above 0.60.The intra-group correlation coefficients, which indicate test-retest reliability, were all greater than 0.70.The content validity index of the questionnaire at the overall level was above 0.90, while the item-level content validity index was more than 0.78. Conclusions:The Chinese grading standards for elderly disability and dementia, which are aligned with the ICF, have been preliminarily established.Visual assessment tools have also been developed, which demonstrate good reliability and validity.Among the two visual assessment tools, GIF dynamic pictures were found to be more popular and easier to understand.

Objective: To analyze physical fitness of students aged 6-22 years old from seven ethnic groups in Yunnan Province, and to provide reference for physical fitness intervention measures. Methods: The nationality, gender, grade, body shape, vital capacity, exercise quality of students were derived from the 2019 Yunnan Student Physical Health Survey Database. Comprehensive physical fitness score was calculated according to the National Student Physical Fitness Standards(revised in 2014). t test, ANOVA, and χ 2 test were used to analyze physical fitness score and level among students with different ethnic groups, gender, and school stages. Results: The average comprehensive score of physical fitness among students from 7 ethnic groups in Yunnan Province was (70.02±9.69）, with the pass rate being 88.91%. The proportion of excellent was 0.93%, good was 17.90%, pass 70.09 %, and failed was 11.09%. Physical fitness score was highest in BMI (94.99 points), followed by 50 meter running (74.13 points), sitting forward bend (72.63 points), endurance running (70.43 points), standing long jump (67.77 points), sit ups ( 65.71 points) , 1 minute skipping rope (65.25 points), vital capacity (62.97 points), pull up (29.04 points). Physical fitness score and pass rate and evaluation level varied significantly by ethnicity and school stage( F =293.53，452.85， χ 2/ χ 2 trend =466.65， 412.57 ； 1 553.22 ，1 045.36， P <0.01). Conclusion The excellent rate of physical fitness among students in Yunnan Province is relatively low. Physical fitness promotion requires specific guidance and training based on ethnicity and school stage.

Objective To investigate the application value of tenofovir alafenamide fumarate (TAF) in elderly patients with chronic hepatitis B (CHB) and its influence on bones and kidneys. Methods A total of 36 CHB patients, aged ≥60 years, who received TAF antiviral therapy in Qingdao Municipal Hospital, The Affiliated Hospital of Qingdao University, Qingdao Sixth People's Hospital, Chengyang People's Hospital, and Jimo People's Hospital from June 2021 to October 2022 were enrolled in this study, and all patients received TAF (25 mg/d) antiviral therapy. Related data were collected at baseline and weeks 24 and 48 of treatment, including virological indicators, biochemical parameters, urinary protein electrophoresis indices, transient elastography (FibroScan), and bone mineral density. Virological indicators included high-sensitivity HBV DNA quantification; biochemical parameters included total bilirubin, direct bilirubin (DBil), indirect bilirubin (IBil), alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase, total bile acid (TBA), glucose, blood urea nitrogen, creatinine, estimated glomerular filtration rate, and cystatin C (Cys C); urinary protein electrophoresis indices included urinary β2 microglobulin (β2-MG), urinary retinol (URBP), and urinary α1 microspherin (α1-MG). The paired t -test was used for comparison of normally distributed continuous data before and after treatment, and the Wilcoxon signed-rank test was used for comparison of non-normally distributed continuous data before and after treatment; the chi-square test or the Fisher's exact test was used for comparison of categorical data. Results A total of 36 CHB patients completed 24 weeks of follow-up. The complete virological response rate after 24 weeks of treatment was higher than that at baseline [83.3% (30/36) vs 77.8% (28/36), χ 2 =0.36, P =0.55], and there were significant reductions in DBil ( t =-2.42, P =0.02) and Cys C ( t =-4.34, P < 0.001) from baseline to week 24. A total of 18 CHB patients completed 48 weeks of follow-up. The complete virological response rate after 48 weeks of treatment was higher than that at baseline (94.4% vs 77.8%, χ 2 =2.22, P =0.34), and there were significant increases in IBil ( t =2.43, P =0.03), TBA ( Z =-2.24, P =0.03), and bone mineral density T score of lumbar vertebra ( t =2.92, P = 0.01) and femoral neck ( t =2.42, P =0.03) and a significant reduction in liver stiffness measurement ( t =-2.31, P =0.03). There were no significant changes in β2-MG, URBP, and α1-MG after treatment (all P > 0.05). Conclusion TAF has a good antiviral effect in CHB patients aged ≥60 years and can help more CHB patients achieve complete virological response, without causing damage to the kidney, and it can also improve bone mineral density and liver fibrosis degree.

Objective:To investigate the distribution and molecular characteristics of Yersinia isolated from diarrhea patients in Jiangsu Province. Methods:From 2017 to 2021, the stool samples of diarrhea patients were collected in Tongshan District of Xuzhou City and Dongtai City of Yancheng City, Jiangsu Province, where the national active monitoring sites of Yersinia enterocolitica, then Yersinia was isolated; meanwhile, suspected Yersinia strains were collected from sentinel hospitals in the province. The DNA of isolated strains was extracted for whole genome resequencing, and the data were uploaded to the EnteroBase database for Yersinia species identification; the original data were cleaned and processed for 16S ribosomal RNA (16S rRNA) gene polymorphism analysis. Five virulence genes (ail, ystA, ystB, yadA, virF) were scanned through the National Center for Biotechnology Information (NCBI) and Pathogen Virulence Factor Database (VFDB), and K-mer Tree was constructed and genomic characteristics were analyzed. Results:From 2017 to 2021, a total of 2 058 stool samples from diarrhea patients were collected, and 57 strains of Yersinia were isolated and identified; meanwhile, two Yersinia strains were collected from the sentinel hospital. Compared with EnteroBase database, 51 strains were identified as Yersinia enterocolitica, 4 strains as Yersinia proxima, 1 strain each as Yersinia aleksiciae, Yersinia massiliensis, Yersinia intermedia and Yersinia canariae. The 16S rRNA gene polymorphism analysis showed that all strains were clustered into 3 groups, which could distinguish Yersinia enterocolitica from other Yersinia. Among the 51 strains of Yersinia enterocolitica, 49 strains were virulence genotype Ⅲ(ail-, ystA-, ystB+, yadA-, virF-), two strains were virulence genotype Ⅱ(ail+, ystA+, ystB-, yadA-, virF-); and 8 other Yersinia strains were virulence genotype Ⅳ (ail-, ystA-, ystB-, yadA-, virF-). K-mer analysis could distinguish Yersinia enterocolitica from other Yersinia, JS-XZ-2020001 strain was far away from other Yersinia enterocolitica isolates, and serotype O8 strains were more concentrated. Conclusions:The clinical isolates of Yersinia enterocolitica from diarrhea patients are mainly Yersinia and other Yersinia co-exist in a small amount in Jiangsu Province, two new Yersinia species ( Yersinia proxima and Yersinia canariae) are discovered. The virulence genotype of Yersinia enterocolitica is mainly type Ⅲ. The 16S rRNA gene polymorphism analysis and K-mer analysis can effectively distinguish Yersinia enterocolitica from other Yersinia.

Objective:To identify latent classes of impulsivity among metabolic surgery patients based on latent class model and determine the relationship between the latent classes of impulsivity and anxiety and depression symptoms.Methods:The 272 obese patients (97 males and 175 females) undergoing metabolic surgery in the Department of Weight Loss and Metabolic of Qilu Hospital of Shandong University from October 2021 to August 2022 were included. The average age was (30.50±6.70) years old and the average body mass index (BMI) was (42.54±6.97) kg/m 2. The survey contents included: demographic and sociological data; impulsivity; anxiety symptoms; depression symptoms. The latent profile analysis (LPA) of impulsivity among metabolic surgery patients was conducted using Mplus 8.3. The comparison of anxiety and depression between different latent classes was analyzed by the binary logistic regression analysis using SPSS 25.0. Results:The research subjects in terms of impulsivity were divided into 3 latent classes: "low impulsivity group" accounted for 32.7%; "high impulsivity group" accounted for 51.8%; "high sensation seeking/positive urgency/negative urgency group" accounted for 15.4%. The binary logistic regression analysis results showed that taking "low impulsivity group" for reference, the risk of positive anxiety and depression was 2.06 ( OR=2.06, 95% CI: 1.08-3.93) and 4.13 ( OR=4.13, 95% CI: 2.17-7.87) times higher for "high impulsivity group" patients than for "low impulsivity group" patients; the risk of positive anxiety and depression was 3.25 ( OR=3.25, 95% CI: 1.42-7.44) and 4.16 ( OR=4.16, 95% CI: 1.82-9.50) times higher for "high sensation seeking/positive urgency/negative urgency group" patients than for "low impulsivity group" patients. Conclusions:The impulsivity of metabolic surgery patients showed obvious heterogeneity and could be divided into 3 types: "low impulsivity group" , "high impulsivity group" , and "high sensation seeking/positive urgency/negative urgency group" . Compared with "low impulsivity group" , "high impulsivity group" and "high sensation seeking/positive urgency/negative urgency group" metabolic surgery patients are most likely to develop anxiety and depressive symptoms.

Objective:To investigate the clinical and genetic characteristics of genetic and metabolic infantile cholestatic hepatopathy (ICH), and to provide evidence for its diagnosis and treatment.Methods:Clinical data and follow-up outcomes of hospitalized children diagnosed with ICH in the Department of Gastroenterology, Children′s Hospital, Capital Institute of Pediatrics from January 2014 to December 2019 were retrospectively analyzed.Among the 80 children, 27 were female and 53 were male, with a mean age of onset of (39±18) days old.Children with confirmed etiology by high-throughput sequencing analysis were included in the genetic metabolic group (44 cases), and those with idiopathic neonatal cholestasis(INC) of unknown etiology after the systematic examination were included in the INC group (36 cases). The t-test or independent sample rank sum test was used to compare the laboratory test results and biochemical indexes.The infection rate of cytomegalovirus was compared by the Chi- square test. Results:(1) A total of 80 cases were included, and 44 cases (55.0%)were confirmed as INC by high-throughput sequencing.Among those with a positive molecular diagnosis, there were 23 cases of citrin deficiency (CD), 10 cases of Alagille syndrome (ALGS), 6 cases of progressive familial intrahepatic cholestasis (PFIC), 2 cases of congenital bile acid synthesis defect, 2 cases of Nieman Pick disease, and 1 case of cystic fibrosis.(2) Serum total bile acid (TBA) and activated partial prothrombin time (APTT) levels in the genetic metabolic group were significantly higher than those in the INC group (all P<0.05). TBA and APTT levels in genetic metabolites were 180.6 (115.5, 271.6) μmol/L and 40.6 (37.1, 45.2) s, respectively, which were 123.3 (98.8, 163.4) μmol/L and 34.8 (31.7, 40.1) s in INC group, respectively.There was no significant difference in the cytomegalovirus infection rate between the 2 groups ( P>0.05). (3)The pathological examination of liver tissue in the genetic metabolic group was worse than that in the INC group, with spot-like and fusion focal-like necrosis, and 5 cases (4 cases of ALGS and 1 case of CD) showed a reduced number of bile ducts in the portal area and lumen stenosis. Conclusions:CD, ALGS and PFIC are the common causes of genetic and metabolic ICH.Fundamental cause of cholestasis should be actively examined in children with cytomegalovirus infection.High-throughput sequencing is of great significance in the accurate diagnosis of ICH.
