OBJECTIVES: To report the development, validation, and findings of the Multi-dimensional Attention Rating Scale (MARS), a self-report tool crafted to evaluate six-dimension attention levels. METHODS: The MARS was developed based on Classical Test Theory (CTT). Totally 202 highly educated healthy adult participants were recruited for reliability and validity tests. Reliability was measured using Cronbach's alpha and test-retest reliability. Structural validity was explored using principal component analysis. Criterion validity was analyzed by correlating MARS scores with the Toronto Hospital Alertness Test (THAT), the Attentional Control Scale (ACS), and the Attention Network Test (ANT). RESULTS: The MARS comprises 12 items spanning six distinct dimensions of attention: focused attention, sustained attention, shifting attention, selective attention, divided attention, and response inhibition.As assessed by six experts, the content validation index (CVI) was 0.95, the Cronbach's alpha for the MARS was 0.78, and the test-retest reliability was 0.81. Four factors were identified (cumulative variance contribution rate 68.79%). The total score of MARS was correlated positively with THAT (r = 0.60, P < 0.01) and ACS (r = 0.78, P < 0.01) and negatively with ANT's reaction time for alerting (r = -0.31, P = 0.049). CONCLUSIONS The MARS can reliably and validly assess six-dimension attention levels in real-world settings and is expected to be a new tool for assessing multi-dimensional attention impairments in different mental disorders.

Objective To investigate the effects of light-at-night exposure on anxiety and depression behaviors in mice and to explore the underlying neural mechanisms.Methods Six-week-old male C57BL/6J mice were randomly assigned to a control(Ctrl)group and a light-at-night exposure(LAN)group.Mice in the LAN group were exposed to 460 nm blue light for 1 h daily during the zeitgeber time(ZT)13-14 while the Ctrl group mice were maintained under a 12-h light/12-h dark cycle.Behavioral tests were conducted at different time points following LAN exposure to evaluate anxiety and depression behaviors in the mice.Immunofluorescence staining was used to observe the effect of LAN on c-fos expressions in the medial prefrontal cortex(mPFC),basal ateral amygdala(BLA),paraventricular nucleus(PVN)and paraventricular thalamus(PVT).ELISA was performed to measure changes in serum corticosterone,adrenocorticotropic hormone(ACTH)and corticotropin-releasing hormone(CRH)levels.Golgi staining was applied to measurethe dendritic spine density and morphology from mPFC and CA1.Western blotting analysis was conducted to detect expression levels of brain-derived neurotrophic factors(BDNFs),phosphorylated tropomyosin receptor kinase B(p-TrkB)/TrkB,postsynaptic density protein 95(PSD95)and synaptophysin(SYP)in the mPFC.Results Mice exhibited anxiety-like behaviors after 14 days of LAN exposure,with depression-like behaviors emerging after 28 days.LAN exposure of 28 days led to a significant increase in the number of c-fos-positive neurons in the mPFC,BLA,PVN and PVT(P＜0.05),resulted in elevated serum corticosterone levels(P＜0.01)and reduced protein expression levels of BDNF and SYP(P＜0.05).Furthermore,there was a marked decrease in synapse numbers and synaptic density in the mPFC(P＜0.01).Conclusion Prolonged exposure to blue light at night enhances neuronal activity in the mPFC and BLA and suppresses the BDNF/TrkB signaling pathway by activating the hypothalamic-pituitary-adrenal axis(HPA),thus leading to synaptic structural and functional damage and inducing anxiety and depression behaviors in mice.

Objective:To investigate the effects of auditory integration training combined with applied behavior analysis(ABA)rehabilitation training on the rehabilitation effect and social skills of children with autism spectrum disorder(ASD).Methods:This study was a prospective randomized controlled study,60 children with ASD admitted to Tongren Rehabilitation Hospital from June 2023 to June 2024 were selected as the research subjects,and divided into control group(n=30)and treatment group(n=30)according to the random double chromosphere method.The control group received ABA rehabilitation training,The treatment group received auditory integration training on the basis of the control group,Both groups were treated for 6 months.The improvement of clinical symptoms,Sensory Integration Function Scale(SIFS),Repetitive Behavior Scale-Revised(RBS-R)between two groups before and after treatment and Self-Rating Anxiety Scale(SAS)score for parents caring for the sick child were compared between two groups.Results:The sensation,communication,physical movement,language,self-care,and total score of the treatment group were all lower than those of the control group(P＜0.05).The language,social skills,sensory perception,behavior and overall score of the treatment group were lower than those of the control group(P＜0.05).The RBS-R and SAS scores of the child's foster parents in the treatment group were lower than those in the control group,while the SIFS score was higher than that in the control group(P＜0.05).Conclusion:The combination of auditory integration training and ABA rehabilitation training can improve the rehabilitation effect of children with ASD,improve their social skills,sensory integration ability,and symptoms of repetitive stereotyped behavior,Relieve the anxiety of parents caring for sick children.

Objective:To investigate the association between cardiometabolic multimorbidity(CMM)and cardiometabolic diseases(CMDs)with frailty in elderly patients suffering from chronic diseases in rural Shandong.Additionally, it seeks to analyze the role of self-efficacy in chronic disease management in mitigating the risk of frailty associated with CMM and CMDs.Methods:A multi-stage cluster random sampling method was employed to select 2, 778 elderly patients aged 60 and above with chronic diseases in rural Shandong Province.Frailty was assessed using the Frailty Phenotype(FP), while self-efficacy in chronic disease management was measured using the Self-Efficacy to Manage Chronic Disease Scale(SEMCD).For the analysis, binary logistic regression and marginal effects were utilized.Results:The prevalence of frailty among elderly patients with chronic diseases in rural Shandong was found to be 12.28%, while the prevalence of CMM was reported at 53.20%.Binary logistic regression analysis revealed that frailty was significantly associated with several factors, including age, education level, annual per capita income, employment status, and self-efficacy in managing chronic disease(all P<0.05).Notably, increases in CMM( P=0.001)and the number of CMDs( P<0.001)were linked to a heightened risk of frailty.Furthermore, marginal effects analysis indicated that individuals in the high self-efficacy group exhibited significantly lower risks of frailty associated with CMM and CMDs compared to those in the low self-efficacy group, with risk reductions of 96.9%(95% CI: -1.258--0.681, P<0.001)and 85.7%(95% CI: -1.175--0.539, P<0.001), respectively. Conclusions:Both the presence of CMM and a higher number of CMDs are linked to an increased risk of frailty.However, elevated levels of self-efficacy in chronic disease management can significantly mitigate the frailty risk associated with CMM and CMDs.It is advisable to enhance health education and self-management training, as well as to establish a comprehensive, multidisciplinary, and multidimensional health management system for the elderly.This approach aims to improve self-efficacy in chronic disease management among rural elderly populations, thereby preventing and addressing the onset of frailty.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

Objective To analyze the risk factors and survival status of Epstein-Barr virus(EBV)infection in pa-tients with aplastic anemia(AA)after haploid allogeneic hematopoietic stem cell transplantation(Haplo-HSCT).Methods Clinical data of 78 AA patients who underwent Haplo-HSCT in the hematology department of a hospital from January 1,2019 to October 31,2022 were analyzed retrospectively.The occurrence and onset time of EBV viremia,EBV-related diseases(EBV diseases),and post-transplant lymphoproliferative disorders(PTLD)were ob-served,risk factors and survival status were analyzed.Results Among the 78 patients,38 were males and 40 were females,with a median age of 33(9-56)years old;53 patients experienced EBV reactivation,with a total inci-dence of 67.9％,and the median time for EBV reactivation was 33(13,416)days after transplantation.Among pa-tients with EBV reactivation,49 cases(62.8％)were simple EBV viremia,2 cases(2.6％)were possible EBV di-seases,and 2 cases(2.6％)were already confirmed EBV diseases(PTLD).Univariate analysis showed that age 1＜40 years old at the time of transplantation,umbilical cord blood infusion,occurrence of acute graft-versus-host disease(aGVHD)after transplantation,and concurrent cytomegalovirus(CMV)infection were independent risk fac-tors for EBV reactivation in AA patients after Haplo-HSCT.Multivariate analysis showed that concurrent CMV in-fection was an independent risk factor for EBV reactivation in A A patients after Haplo-HSCT(P=0.048).Ritu-ximab intervention before stem cell reinfusion was a factor affecting the duration of EBV reactivation(P＜0.05).The mortality of EBV viremia,EBV diseases,and PTLD alone were 8.2％,50.0％,and 100％,respectively.The 2-year overall survival rate of patients with and without EBV reactivation were 85.3％,and 90.7％,respectively,difference was not statistically significant(P=0.897).However,patients treated with rituximab had 2-year lower survival rate than those who did not use it,with a statistically significant difference(P=0.046).Conclusion EBV reactivation is one of the serious complications in AA patients after Haplo-HSCT,which affects the prognosis and survival of patients.

Objective To investigate the risk factors of in-hospital mortality and establish a risk prediction model for patients receiving venoarterial extracorporeal membrane oxygenation(VA-ECMO).Methods We retrospectively collected the data of 302 patients receiving VA-ECMO in ICU of 3 hospitals in Guangdong Province between January,2015 and January,2022 using a convenience sampling method.The patients were divided into a derivation cohort(201 cases)and a validation cohort(101 cases).Univariate and multivariate logistic regression analyses were used to analyze the risk factors for in-hospital death of these patients,based on which a risk prediction model was established in the form of a nomogram.The receiver operator characteristic(ROC)curve,calibration curve and clinical decision curve were used to evaluate the discrimination ability,calibration and clinical validity of this model.Results The in-hospital mortality risk prediction model was established based the risk factors including hypertension(OR=3.694,95%CI:1.582-8.621),continuous renal replacement therapy(OR=9.661,95%CI:4.103-22.745),elevated Na2+ level(OR=1.048,95%CI:1.003-1.095)and increased hemoglobin level(OR=0.987,95%CI:0.977-0.998).In the derivation cohort,the area under the ROC curve(AUC)of this model was 0.829(95%CI:0.770-0.889),greater than those of the 4 single factors(all AUC<0.800),APACHE Ⅱ Score(AUC=0.777,95%CI:0.714-0.840)and the SOFA Score(AUC=0.721,95%CI:0.647-0.796).The results of internal validation showed that the AUC of the model was 0.774(95%CI:0.679-0.869),and the goodness of fit test showed a good fitting of this model(χ2=4.629,P>0.05).Conclusion The risk prediction model for in-hospital mortality of patients on VA-ECMO has good differentiation,calibration and clinical effectiveness and outperforms the commonly used disease severity scoring system,and thus can be used for assessing disease severity and prognostic risk level in critically ill patients.
