Objective To explore the current situation of disease perception in patients with tophi and its correlation with the quality of life. Methods A retrospective analysis was conducted on 303 gout patients admitted to the Shanghai Sixth People's Hospital from January 2023 to December 2024. The patients were classified into tophi gout (n=150) and non-tophi gout (n=153) groups based on whether they were tophi gout or not. The current disease perception status and quality of life of the two groups were compared using Simplified Chinese Version of the Disease Cognition Questionnaire (BIPQ) and Short Form of Health Survey (SF-36). Logistic regression was used to analyze the influencing factors of the quality of life of patients with tophi gout. Results Compared with the non-tophaceous gout group, the tophaceous gout group had a higher BIPQ score, and a lower SF-36 score (P<0.05). Among patients with tophaceous gout, 80 cases had good quality of life, and 70 cases had poor quality of life. These patients were included in the good quality of life group (n=80) and the poor quality of life group (n=70), respectively. Compared with the good quality of life group, patients in the poor quality of life group had longer gout course and average duration of each gout attack, as well as higher 20-item tophi impact questionnaire (TIQ-20) score and BIPQ score (P<0.05). Logistic regression analysis showed that the course of gout (OR=1.070, 95% CI: 1.017-1.126, P=0.009), TIQ-20 score (OR=1.048, 95% CI: 1.022-1.075, P<0.001), and BIPQ score (OR=1.055, 95%CI: 1.009-1.104, P=0.019) were risk factors affecting the quality of life in patients with tophaceous gout (P<0.05). Conclusion The course of gout, TIQ-20 score and BIPQ score are risk factors affecting the quality of life of patients with tophi gout.

The rich club, as a community of highly interconnected nodes, serves as the topological center of the network. However, the similarities and differences in how the rich club supports functional integration and segregation in the brain across different species remain unknown. In this study, we first detected and validated the rich club in the structural networks of mouse, monkey, and human brains using neuronal tracing or diffusion magnetic resonance imaging data. Further, we assessed the role of rich clubs in functional integration, segregation, and balance using quantitative metrics. Our results indicate that the presence of a rich club facilitates whole-brain functional integration in all three species, with the functional networks of higher species exhibiting greater integration. These findings are expected to help to understand the relationship between brain structure and function from the perspective of brain evolution.

Objective: To examine the mediating effect of resilience on AIDS-related stress and patient-reported outcome among elderly cases with HIV/AIDS, so as to provide the basis for promoting mental health and improving health outcomes of this population. Methods: From June to July 2024, elderly cases with HIV/AIDS receiving treatment in the infectious diseases department of a tertiary-level hospital in Sichuan Province and undergoing follow-up management at 12 community health service centers in Wuhou District, Chengdu City, Sichuan Province, were selected as study participants using convenience sampling method. Data on demographic information, duration since confirmed diagnosis and the most recent CD4+T lymphocyte count were collected through questionnaire surveys. The Chinese versions of the HIV/AIDS Stress Scale, the Chinese versions of the 10-item Connor-Davidson Resilience Scale, and the Patient-Reported Outcome Scale for Elderly HIV/AIDS Patients were used to assess AIDS-related stress, resilience, and patient-reported outcome, respectively. Structural equation modeling was performed using Mplus 8.3 software to analyze the mediating effect of resilience on AIDS-related stress and patient-reported outcome. The Bootstrap method was employed to test the significance of the mediating effect. Results: A total of 424 elderly HIV/AIDS cases were included, with a mean age of (62.04±8.73) years. Among them, 315 (74.29%) were males and 109 (25.71%) were females. The median scores were 23.00 (interquartile range, 11.00) points for AIDS-related stress, 30.00 (interquartile range, 7.00) points for resilience, and 363.45 (interquartile range, 53.03) points for the total score of patient-reported outcome. Resultsof the mediation effect analysis revealed that AIDS-related stress had a direct negative effect on patient-reported outcome (β=-0.608, 95%CI: -0.742 to -0.465). It also exerted an indirect negative effect on patient-reported outcome through the mediating role of resilience (β=-0.258, 95%CI: -0.364 to -0.158), with the mediating effect accounting for 29.79% of the total effect. Conclusion AIDS-related stress among elderly cases with HIV/AIDS can directly or indirectly negatively affect patient-reported outcome through resilience.

Objective:To investigate the risk factors for esophageal varices in patients with liver cirrhosis,to establish a predictive model,and to provide reasonable guidance for the prevention of early esophageal varices in patients with liver cirrhosis.Methods:A retrospective analysis was performed for 1 113 patients with liver cirrhosis who attended the hospitals in Chongqing,China from Decem-ber 2006 to May 2021.Recursive feature elimination(RFE)and four machine learning methods were used for the screening of features,and five machine learning predictive models were established by logistic regression,random forest,support vector machine(SVM),de-cision tree,and eXtreme Gradient Boosting(XGBoost).The receiver operating characteristic(ROC)curve was used to evaluate the per-formance of each model,and the model with the best performance was used to investigate the risk factors for esophageal varices in pa-tients with liver cirrhosis.SHAP plots were used to explain the impact of each risk factor on patients.Results:The XGBoost model showed the best performance in predicting the risk of esophageal varices in patients with liver cirrhosis,with an area under the ROC curve of 0.872(95%CI=0.813-0.918).SHAP plots showed that platelet count,diameter of the portal vein,cholinesterase,albumin,ala-nine aminotransferase,hemoglobin,prothrombin ratio,prothrombin time,and serum total protein were risk factors for esophageal vari-ces in patients with liver cirrhosis.Conclusion:This study shows that the XGBoost predictive model has a relatively high predictive value,and the risk factors obtained by this model have a certain guiding significance for the clinical prevention and treatment of early esophageal varices in patients with liver cirrhosis.

Objective To investigate the effectiveness of a nurse-led surgical wound management model in postoperative wound care for patients undergoing tophi surgery.Methods A total of 52 post-operative tophi surgery patients were randomly divided into control and observation groups,with 26 ca-ses each.The control group received routine postoperative care,while the observation group was man-aged nurse-led surgical wound management model in addition to routine care.Postoperative complica-tion rates,hospitalization duration and costs,quality of life[evaluated by Quality of Life(QOL)],nursing satisfaction,pain intensity[evaluated by Numberic Rating Scale(NRS)],and wound recov-ery[evaluated by Wound Bed Score(WBS)]were compared between the two groups.Results The observation group demonstrated significantly shorter hospitalization duration,lower costs,fewer compli-cations,and higher nursing satisfaction compared to the control group(P＜0.05).Additionally,the ob-servation group exhibited superior QOL scores(after intervention),lower NRS scores(postoperative day 1,3,7),and improved WBS scores(postoperative day 3,7,14)(P＜0.05).Conclusion The nurse-led surgical wound management model enhances postoperative recovery in tophi surgery patients by accelerating wound healing,reducing pain duration and shortening hospitalization time,lowering costs and complication rates,and improving quality of life.

OBJECTIVE To establish fingerprints and multi-components determination of Jieze lotion, and use chemometrics methods for quality evaluation. METHODS The HPLC-DAD fingerprints was established and 10 components were recognized by comparison with references. Meanwhile, their contents were determined. The data were evaluated by the methods of chemometrics such as similarity evaluation, cluster analysis, principal component analysis, and orthogonal partial least squares-discriminant analysis. RESULTS The similarity of 11 batches of Jieze lotion were all >0.95. The linearity was good(r≥0. 999 1) and the average recoveries were between 89.70% and 106.0% with the RSD of 1.52%−3.41%. Instrument precision, stability and reproducibility of the method were all great. The contents of the common ten components(gallic acid, protocatechuic acid, neochlorogenic acid, caftaricacid, 5-O-feruloylquinicacid, chlorogenic acid, phellodendrine chloride, magnoflorine, 4-O-feruloylquinic acid, berberinehydrochloride) were 40.103−55.841, 2.347−6.179, 8.336−23.810, 7.084−21.956, 33.098−53.833, 24.597−49.610, 21.587−31.188, 5.915−13.162, 115.381−189.702, 31.378−112.686 μg·mL−1, respectively.
