Objective:To explore the latent classes of health behavior and explore the predictive factors among stroke patients.Methods:A total of 1 250 participants were recruited using cluster random sampling in September 2022. The general information, the modified Rankin scale(mRS), stroke prevention knowledge questionnaire(SPKQ), health behavior scale for stroke patients (HBS-SP), and short form-health belief model scale (SF-HBMS) were administered in the cross-sectional survey. Mplus 8.3 software was used to conduct a latent class analysis (LCA) on the health behavior of stroke patients, and SPSS 27.0 software was used to carry out multinomial Logistic regression to analyze the predictive factors of different latent classes of health behavior of stroke patients.Results:The health behavior of stroke patients obtained three latent classes: low health behaviors-lack of health responsibility group (66.9%, n=794), moderate health behaviors-poor compliance group (11.9%, n=141), and good health behaviors-insufficient exercise group (21.2%, n=251). Compared with good health behaviors-insufficient exercise group, stroke patients with shorter duration education time ( B=-0.589, OR=0.555, P=0.036), hemorrhagic stroke ( B=0.082, OR=1.086, P<0.001), fewer comorbidities ( B=-0.022, OR=0.978, P=0.026), higher mRS score ( B=-0.046, OR=1.047, P=0.004), lower SPKQ score ( B=-0.055, OR=0.947, P=0.016), and lower SF-HBMS score ( B=-0.085, OR=0.919, P<0.001) were more likely to be included in moderate health behaviors-poor compliance group. However, stroke patients with shorter duration education time ( B=-0.026, OR=0.974, P=0.003), rural areas dwelling ( B=0.800, OR=2.225, P=0.004), fewer comorbidities ( B=-0.056, OR=0.945, P<0.001), lower SPKQ score ( B=-0.101, OR=0.904, P<0.001), and lower SF-HBMS score ( B=-0.071, OR=0.931, P<0.001) were more likely to be included in low health behaviors-lack of health responsibility group. Conclusion:The health behavior of stroke patients has three latent classes. A targeted intervention should be carried out according to the characteristics of different classes to improve their health behavior levels.

Objective:To explore the effects of dopamine receptor D2(DRD2)on astrocytic dedifferentiation based on SOX2-regulated genes in neural stem cells(NSCs)and astrocytes.Methods:Immunofluorescence staining and SOX2-GFP mice were used to examine the lineage differentiation of SOX2-positive cells during the development of cere-bral cortex.Primary NSCs/astrocytes culture,ChIP-seq and Western Blot were adopted to analyze and verify the expres-sion of candidate genes.Pharmacological manipulation,neurosphere formation,photochemical ischemia,immunofluo-rescence staining and behavior tests were adopted to evaluate the effects of activating DRD2 signaling on astrocytic dedif-ferentiation.Results:Immunofluorescence staining demonstrated the NSC-astrocyte switch of SOX2-expression in the normal development of cerebral cortex.ChIP-seq revealed enrichment of DRD2 signaling by SOX2-bound enhancers in NSCs and SOX2-bound promoters in astrocytes.Western Blot and immunofluorescence staining verified the expression of DRD2 in NSCs and reactive astrocytes.Application of quinagolide hydrocholoride(QH),an agonist of DRD2,signifi-cantly promoted astrocytic dedifferentiation both in vitro and in vivo following ischemia.In addition,quinagolide hydro-choloride treatment improved locomotion recovery.Conclusion:Activating DRD2 signaling facilitates astrocytic dedif-ferentiation and may be used to treat ischemic stroke.

Objective:To explore the latent profile types of capability-opportunity-motivation-behavior in stroke patients and analyze the influencing factors of different latent profiles.Methods:From January to October 2023, totally 596 stroke patients from the Neurology Department of five ClassⅢ Grade A hospitals in Henan Province were selected by stratified random sampling. The patients were surveyed using a general information questionnaire, the Stroke Prevention Knowledge Questionnaire (SPKQ), the Social Support Rating Scale (SSRS), the WHO's Quality of Life Questionnaire- Brief Version (WHOQOL-BREF), the Short Form Health Belief Model Scale (SF-HBMS), and the Health Promoting Lifestyle ProfileⅡ (HPLPⅡ). Latent profile analysis was used to classify the capability-opportunity-motivation-behavior characteristics of stroke patients, and multiple logistic regression was conducted to explore the influencing factors of different latent profiles.Results:Three latent profiles of capability-opportunity-motivation-behavior in stroke patients were identified, including low capability-opportunity-motivation-behavior with high health beliefs (32.4%, 193/596), moderate capability-opportunity-motivation-behavior with insufficient health beliefs (47.5%, 283/596), and high capability-opportunity-motivation-behavior with lack of social support (20.1%, 120/596). Multiple logistic regression analysis showed that educational level, smoking history, family history, body mass index, and Charlson Comorbidity Index score were influencing factors of different latent profiles ( P<0.05) . Conclusions:Stroke patients exhibit distinct classifications of capability-opportunity-motivation-behavior. Targeted interventions should be conducted based on the characteristics of each category to improve health behavior management outcomes in patients.

Objective:To explore the mediating effect of rumination between self-perceived burden (SPB) and stigma in stroke patients, so as to provide theoretical basis for the development of targeted nursing interventions in clinical practice.Methods:In September 2022, cluster sampling was used to select 1 126 stroke patients admitted to Department of Neurology of five ClassⅢ Grade A hospitals in Henan Province as subjects. General Information Questionnaire, Self-Perceived Burden Scale (SPBS), Stroke Stigma Scale (SSS), and Chinese Version of Event Related Rumination Inventory (C-ERRI) were used to investigate stroke patients. Pearson correlation analysis was used to explore the correlation between SPB, rumination, and stigma. AMOS 28.0 software was used to establish the structural equation model, and Bootstrap method was used to test the mediating effect.Results:A total of 1 126 questionnaires were distributed, and 1 026 valid questionnaires were collected, with a valid response rate of 91.12% (1 026/1 126). SPBS score of 1 026 stroke patients was (28.68±8.32), the SSS score was (40.53±9.48) and the C-ERRI score was (25.43±12.62). Pearson correlation analysis showed that SPB in stroke patients was positively correlated with stigma and rumination ( P<0.01), and rumination was positively correlated with stigma ( P<0.01). Bootstrap mediating effect test showed that rumination partially mediated the relationship between SPB and stigma in stroke patients, accounting for 55.15% of the total effect. Conclusions:SPB of stroke patients both directly affect stigma and indirectly affect stigma through rumination. Clinical nursing workers should promptly evaluate patients' SPB, pay attention to the mediating role of rumination, develop effective psychological intervention programs, implement personalized and targeted nursing measures, relieve patients' stigma, and improve treatment and rehabilitation compliance.

Objective:To understand the research status and hotspots in the field of stroke health management at home and abroad, and to provide insights for stroke health management research in China.Methods:Relevant literature on stroke health management published between 2013 and 2023 was retrieved from the Web of Science Core Collection and China National Knowledge Infrastructure databases. CiteSpace 6.1.R6 was used for the visual analysis of the number of publications, authors, institutions, countries, and keywords.Results:A total of 382 relevant articles were included, with 169 in English and 213 in Chinese. The number of publications on stroke health management showed a fluctuating upward trend. Research hotspots and frontiers in stroke health management mainly focused on telemedicine, big data and "Internet+", primary and secondary prevention, risk prediction models, quality of life, and swallowing disorders. Future research trends may focus on management models for post-stroke swallowing disorders, risk identification, and the role of caregivers in remote rehabilitation interventions.Conclusions:Researchers can refer to the research hotspots and trends shown by the visual analysis, with particular attention to health management models for patients with post-stroke swallowing disorders and issues related to remote intervention rehabilitation.

Objective:To investigate the relationship between early international normalized ratio(INR)and overanticoagulation in elderly patients with atrial fibrillation(AF)treated with Warfarin, and to evaluate its clinical value in predicting overanticoagulation.Methods:A total of 470 elderly patients with AF treated with Warfarin for anticoagulation were enrolled retrospectively.INR was detected in the morning of the next day after 3 days and 7 days of Warfarin treatment.According to whether INR was greater than 3.0 after 7 days of Warfarin treatment, the patients were divided into over-anticoagulation group(n=107)and non-over-anticoagulation group(n=363). The general clinical data of the two groups were analyzed.The receiver operating characteristic curve(ROC)was used to evaluate the value of 3-day INR(early INR)level in predicting overanticoagulation.Logistic regression was used to analyze the factors related to overanticoagulation in elderly AF patients receiving Warfarin treatment.Results:The age, initial warfarin dose, early INR and serum aspartate transferase level in the over-anticoagulation group were higher than those in the non-over-anticoagulation group( P<0.05 for all). The proportions of patients with initial Warfarin dose≥2.5 mg, age≥70 years old, body weight≤65 kg, valvular atrial fibrillation, hypoproteinemia, abnormal liver function, and combined use of antibiotics were higher in the over-anticoagulation group than those in the non-over-anticoagulation group( P<0.05 for all). The body weight, serum albumin level and the proportion of diabetes mellitus in the over-anticoagulation group were lower than those in the non-over-anticoagulation group( P<0.05). ROC curve showed that the area under the curve(AUC)of early INR in predicting over-anticoagulation was 0.927(95% CI: 0.900-0.949, P<0.0001), the sensitivity was 82.86% and the specificity was 88.43%, the optimal cutoff value for predicting overanticoagulation was INR≥1.66.Multiple Logistic regression analysis showed that early INR level≥1.66( OR=33.871, P<0.001), initial warfarin dose≥2.5 mg( OR=17.062, P=0.011), body weight≤65 kg( OR=2.824, P=0.002), age≥70 years old( OR=2.678, P=0.003), and abnormal liver function( OR=2.091, P=0.022)were related factors for over-anticoagulation in elderly patients with atrial fibrillation. Conclusions:Early INR level is closely related to overuse of anticoagulation in elderly AF patients receiving Warfarin treatment, which can be regarded as a predictor of overuse of anticoagulation.Early INR level in elderly AF patients receiving warfarin treatment should be monitored to reduce the incidence of anticoagulant overuse.

Objective:To construct an evaluation indicator system for the health management effects in high-risk stroke population.Methods:From March to May 2020, based on health ecology theory, social cognitive theory and knowledge, attitude/belief, practice theory, the first draft of the evaluation index system for health management effects of high-risk stroke groups was drawn up by literature review and group discussion. Through two rounds of Delphi expert consultation, the evaluation index system of health management effects of high-risk stroke groups was established, and the weight of each index was determined by analytic hierarchy process (AHP). A total of 22 experts were invited to participate in expert consultation. Twenty-two questionnaires were sent out in the first round, and 20 questionnaires were recovered, of which 20 were valid (90.9%). In the second round of correspondence, 20 questionnaires were sent out and 19 questionnaires were recovered, of which 19 were valid (95.0%).Results:The authority coefficients of the two rounds of expert consultation (Cr) was 0.933 and 0.937, respectively. The Kendall coordination coefficients W of importance in the second round was significantly higher than that in the first round (0.299 vs 0.172) ( P<0.001). The mean of importance score (Mj) of each index was 4.10-5.00, coefficient of variation (CV) was 0-0.235, and full mark ratio (Kj) was 0.26-1.00. Finally, an evaluation index system of the health management effects for high-risk stroke population was constructed, which included 3 first-level indicators (individual characteristics, behavior style, environmental support), 12 second-level indicators and 58 third-level indicators. Conclusions:The evaluation index system of the health management effects for high-risk stroke population is established in this study, which provides scientific quantitative indicators and evaluation tools. The enthusiasm, authority and coordination of consultation experts are strong, which indicates that the indicator system is feasible.

Objective:To investigate the effect of preoperative use of diuretics on cardiac surgery-associated acute kidney injury(CSA-AKI)in elderly patients.Methods:In this single-center retrospective study, 1 638 patients aged ≥60 years and undergone cardiac surgery(including coronary artery bypass grafting, valve replacement and valvuloplasty)in the Department of Cardiovascular Surgery, Linyi People's Hospital between January 2015 and December 2022 were recruited.The last preoperative serum creatinine(SCr)level was taken as the baseline value, and AKI was diagnosed according to the Kidney Disease Improving Global Outcomes(KDIGO)criteria.Patients were divided into an AKI group and a non-AKI group according to whether AKI occurred after surgery.The clinical characteristics of the two groups were compared, and the effect of preoperative use of diuretics on CSA-AKI was evaluated by multivariate Logistic regression analysis.Results:Of 1638 patients enrolled in the study, 284 patients(17.3%)developed CSA-AKI.Compared with the non-AKI group, there were higher proportions of patients in the AKI group receiving furosemide(62.7% or 178/284 vs.46.2% or 626/1 354, χ2=25.397, P<0.001), spironolactone(70.1% or 199/284 vs.49.9% or 676/1 354, χ2=38.284, P<0.001), and hydrochlorothiazide(8.1% or 23/284 vs.3.5% or 47/1354, χ2=12.288, P<0.001). The number of diuretics in the AKI group was higher than in the non-AKI group[2(0, 2) vs.1(0, 2), Z=-6.381, P<0.001], and the proportion of patients using ≥2 diuretics was higher in the AKI group than in the non-AKI group(70.1% or 199/284 vs.49.0% or 664/1354, χ2=41.652, P<0.001). Multivariate Logistic regression analysis showed that, after adjusting for hypertension, diabetes mellitus, hypoalbuminemia, NYHA functional class Ⅲ/Ⅳ, cardiopulmonary bypass during surgery, operative duration≥6 h, postoperative blood transfusion>600 ml, postoperative use of >3 vasoactive drugs and other variables, preoperative use of ≥2 diuretics remained an independent risk factor for CSA-AKI in elderly patients( OR=1.580, 95% CI: 1.042-2.396, P=0.031). Conclusions:AKI is a common complication after cardiac surgery in elderly patients.Preoperative use of ≥2 diuretics used may be an independent risk factor for CSA-AKI.

Objective:To conduct a scoping review of domestic and international guidelines on high-intensity physical activity, low-intensity physical activity, sedentary behavior, and sleep in adults, in order to understand the best combination of 24-hour activity and behavior for promoting adult health development, and to provide guidance for research in this field.Methods:Based on the scoping review guidelines of the Joanna Briggs Institute (JBI) of Australia as a methodological framework, we searched PubMed, Embase, Ovid, CINAHL, ClinicalKey, CNKI, Wanfang, MEDLINK Clinical Guidelines Network, UpToDate, BMJ Best Practice, International Guidelines Network, US National Guidelines Library, UK National Clinical Optimization Research Institute and Scotland Intercollegiate Guidelines Network. Guidelines that made recommendations for different intensity physical activities, sedentary behavior, and sleep in adults over a 24-hour period were included. The search time limit was from January 1, 2010, to August 31, 2022, and included literature was summarized and analyzed.Results:A total of 11 guidelines were included, of which only 2 guidelines from Canada and Saudi Arabia made specific time recommendations for 24-hour physical activity (frequency, intensity, type, and time) , sedentary time, and sleep in adults. The remaining 9 guidelines only made recommendations for adult physical activity and sedentary behavior, or only for physical activity.Conclusions:Future research should comprehensively measure the impact of the best time distribution of physical activity, sedentary behavior, and sleep on physical and mental health, and develop personalized guidelines on 24-hour activity suitable for the national conditions of China.
