Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

Objective:To investigate the status quo and influencing factors of support perception of spouses of breast cancer patients, and to provide reference for clinical intervention.Methods:A cross-sectional study was conducted to facilitate the selection of 180 breast cancer patients who were treated at the Sun Yat-sen University Cancer Center from January 2022 to June 2023. The general information questionnaire, the Perceived Support Scale for Spouses of Breast Cancer Patients, the Hospital Anxiety and Depression Scale, the Locke-Wallace Marriage Adjustment Scale, and the Brief Illness Perception Questionnaire were used to investigate them. Multiple linear regression was used to analyze the influencing factors of perceived support level of spouses of breast cancer patients.Results:A total of 180 patients were admitted ultimately, all of them were females, aged (49.88 ± 8.95) years old. The total score of Perceived Support Scale for Spouses of Breast Cancer Patients was (62.38 ± 6.54) points. The average scores of each dimension from high to low were emotional support (2.70 ± 0.48) points, information support (2.65 ± 0.52) points and actual support (2.51 ± 0.62) points. There were significant differences in the scores of spouse support perception among breast cancer patients with different educational levels, surgical methods and self-care ability ( F=4.08, 17.63, t=2.41, all P<0.05). Pearson correlation analysis showed that the total score of Perceived Support Scale for Spouses of Breast Cancer Patients was negatively correlated with anxiety score, depression score and disease perception score ( r=-0.388, -0.410, -0.350, all P<0.01), and positively correlated with marital adjustment score ( r=0.692, P<0.01). The results of multiple linear regression showed that education level, surgical method, anxiety, depression, disease perception and marital adjustment were the influencing factors of spouse support perception level of breast cancer patients ( t values were 3.04-4.44, all P<0.05 ), which could explain 54.6 % of the total variation. Conclusions:The level of support perception of spouses of breast cancer patients needs to be improved. Education level, surgical method, anxiety, depression, disease perception and marital adjustment are the influencing factors of patients ′ perception of spouse support level.

Objective To analyze the effect of night-shift work, anxiety and their interaction on work-related musculoskeletal disorders (WMSDs) among electronics manufacturing employees. Methods A total of 2 676 employees from 58 electronic manufacturing enterprises in the Pearl River Delta region of Guangdong Province were selected as the research subjects using the judgment sampling method. The Basic Situation Survey Scale, Generalized Anxiety Disorder 7-item Scale and Questionnaire of Musculoskeletal Disorders were used to assess night-shift work, anxiety and the prevalence of WMSDs in employees. The multivariate logistic regression model was used to analyze the effects of night-shift work, anxiety and their combined effects on the risk of WMSDs. Results The proportion of night-shift work was 30.3%, and the detection rates of anxiety and WMSDs were 26.8% and 41.3%, respectively. The results of multivariate logistic regression analysis showed that night-shift work and anxiety were independent risk factors of WMSDs in the research subjects, after excluding the influence of confounding factors such as age, marital status, enterprise size and length of service [odds ratio (OR) and 95% confidence interval (CI) were 1.307 (1.092-1.564) and 3.282 (2.739-3.934), respectively, both P<0.01]. Compared with those without night-shift work or anxiety, the risk of WMSDs was higher in individuals with only night-shift work, only anxiety, or both night-shift work and anxiety [OR and 95%CI were 1.347 (1.091-1.663), 3.395 (2.727-4.227) and 4.117 (3.072-5.519), respectively, all P<0.01]. Conclusion Both night-shift work and anxiety can increase the risk of WMSDs among electronic manufacturing employees, and these two factors exhibit a synergistic effect in increasing the risk of WMSDs.

Objective:To analyze the predictive value of four scoring systems,Pediatric Clinical Illness Score (PCIS),Pediatric Logistic Organ Dysfunction Score 2 (PELOD-2),Pediatric Risk of Mortality Ⅲ (PRISM Ⅲ),and Pediatric Sequential Organ Failure Assessment (pSOFA),in the severity and prognosis in pediatric sepsis.Methods:The medical records of 159 children with sepsis who admitted to PICU at the First Hospital of Jilin University between August 2015 and December 2020 were retrospectively analyzed.The PCIS,PELOD-2,PRISM Ⅲ and pSOFA scores were calculated according to the worst value of each index within 24 h of admission.The children were divided into survival group and death group based on clinical outcomes during hospitalization.The children were stratified according to the severity of sepsis into sepsis (no organ dysfunction) group ( n=18) and severe sepsis group ( n=141).The receiver operator characteristic (ROC) curve was used to evaluate the value of PCIS,PELOD-2,PRISM Ⅲ and pSOFA scores in predicting the severity and prognosis in pediatric sepsis. Results:There were 97 (61.01%) cases in the survival group and 62(38.99%) cases in the death group.There were 141(88.68%) children with severe sepsis.The areas under curve (AUCs) of PCIS,PELOD-2,PRISM Ⅲ and pSOFA scores for predicting severe sepsis in children with sepsis were 0.869,0.875,0.672 and 0.933,respectively (all P <0.05).The AUCs of PCIS,PELOD-2,PRISM Ⅲ and pSOFA scores for predicting the death of children with sepsis in PICU were 0.687,0.697,0.716 and 0.656,respectively (all P<0.05). Conclusion:Among the four scoring systems,the pSOFA scoring system had the highest predictive power for the severity of sepsis.The PRISM Ⅲ score had higher value in assessing the risk of death in all patients with sepsis.

Objective To develop the symptom terminology standard of dampness syndrome,and to provide reference for researches related to the dampness syndrome.Methods According to the workflow of The Principle and Method of Examining and Approving the Terminology in Science and Technology,we conducted the research as the following process:collecting symptoms,denominating symptoms and defining symptoms.First,we merged symptoms according to their intension and extension,and made symptoms independency based on their dampness characteristics and diagnostic value.We also included negative symptoms if they had diagnostic value on dampness syndrome.And then we denominated symptoms following the principle of monosemy and scientificity.Previous researches on symptom terminology usually gave symptom term nominal definitions,while in this study we gave the symptom terms operational definitions,including intension and application operationalization.Besides,based on symptom characteristics we developed symptomatic grading and quantification criteria.At last,the above-mentioned were optimized and confirmed based on the expert opinions.Results In this study,we denominated and defined forty-two symptoms,and also developed symptomatic grading and quantification criteria for them.Conclusion We developed symptom terminology standard for dampness syndrome.This study especially valued symptom independence and symptom terms operational definitions,which could give dampness syndrome diagnosis and evaluation real practice significance,and serve well for scientific researches and clinical practice.

Grey matter (GM) alterations may contribute to cognitive decline in individuals with white matter hyperintensities (WMH) but no consensus has yet emerged. Here, we investigated cortical thickness and grey matter volume in 23 WMH patients with mild cognitive impairment (WMH-MCI), 43 WMH patients without cognitive impairment, and 55 healthy controls. Both WMH groups showed GM atrophy in the bilateral thalamus, fronto-insular cortices, and several parietal-temporal regions, and the WMH-MCI group showed more extensive and severe GM atrophy. The GM atrophy in the thalamus and fronto-insular cortices was associated with cognitive decline in the WMH-MCI patients and may mediate the relationship between WMH and cognition in WMH patients. Furthermore, the main results were well replicated in an independent dataset from the Alzheimer's Disease Neuroimaging Initiative database and in other control analyses. These comprehensive results provide robust evidence of specific GM alterations underlying WMH and subsequent cognitive impairment.
