Objective To investigate the sleep architecture in dementia with Lewy bodies (DLB),and study the sleep architecture and cognitive functions in DLB.Methods We described polysomnography (PSG) findings in 34 consecutive subjects diagnosed with DLB.All the patients underwent Mini-Mental State Examination (MMSE),Montreal Cognitive Assessment (MoCA),Clinical Dementia Rating (CDR) to quantify cognitive functions.Results (1)Sleep architecture analysis:DLB group compared to normal control group,the sleep period time (SPT) was reduced (P ＜ 0.05),total sleep time (TST) and sleep efficiency (SE) were decreased,total wake time (TWT) and wake after sleep onset (WASO) were increased,1 non-rapid eye movement (NREM) sleep (TS1),2NREM sleep (TS2),total NREM sleep (TNREMS),and REM sleep (TREMS) time were significantly decreased (P ＜0.01).(2)The DLB patients were divided into groups based on MMSE,MoCA,qnd CDR scores,the sleep architecture of each group was no significant difference (P ＞ 0.05).Conclusions Patients with DLB exists sleep architecture disorder.The cognitive functions and sleep architecture changes in patients with DLB have no obvious correlation.It is different from other degenerative dementia.

Objective:To explore the mediating effect of nurse professional self-concept between autonomous learning ability and perceived professional benefit.Methods:From April to June 2019, 295 nurses from two hospitals in Yanbian were selected as the research subject by convenience sampling. A survey was conducted on nurses using the General Information Questionnaire, Questionnaire of Nurses' Perceived Professional Benefits, Rating Scale of Self-directed Learning Competence for Nurses, and Professional Self-concept Scale of Nurses. A total of 295 questionnaires were distributed, and 290 valid questionnaires were collected, with an effective response rate of 98.3% (290/295) .Results:290 nurses scored (133.49±21.75) on the Questionnaire of Nurses' Perceived Professional Benefits, (129.74±26.08) on the Rating Scale of Self-directed Learning Competence for Nurses, and (89.39±14.65) on the Professional Self-concept Scale of Nurses. Pearson correlation analysis results showed that there were positive correlations among nurses' perceived professional benefit, autonomous learning ability, and professional self-concept ( P<0.05). The stepwise regression analysis showed that nurse professional self-concept played a complete mediating effect between nurse autonomous learning ability and perceived professional benefit. Conclusions:Nurses' professional self-concept plays a complete mediating effect between autonomous learning ability and nurses' perceived professional benefit. Effective intervention in nurses' professional self-concept and autonomous learning ability is an important way to enhance their perceived professional benefit.

Injection fear is widespread in the population, which can cause patients to tolerate or avoid injection, reduce treatment compliance, and increase the burden of healthcare. Choosing appropriate injection fear assessment tools in clinical practice is helpful to understand the degree, psychological characteristics and influencing factors of individual injection fear. In this paper, the contents, characteristics and application methods of fear of injection assessment tools at home and abroad are reviewed, in order to provide reference for the application and development of fear of injection assessment tools for medical staff.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
