Objective To analyse the research motives and its influencing factors of nursing staff.Methods 1000 authors who wrote for “Nursing Research” were chosen with a random code sampling method and were surveyed with a questionnaire,which inquired about their research motivation and self-rated research ability scale.Results Nursing research motives include to summarise clinical experience66.2％ (524/793),to get promotion 55.4％ (420/793),to contribute to nursing profession 37.2％ (295/793),to report research achievements 35.6％ (282/793),and to meet the requirements of the institution17.5％ (139/793).Research motives were statistically different in terms of age,work expirence,educational background,professional title,attitude,research training,research ability,and work institution (P =0.013,0.037,0.048,0.002,0.024,0.008,0.005,0.009,0.004,P＜0.05).Conclusions To stimulate the enthusiasm for research in nursing staff,administrators need to pay great attention to higher education for nurses,enhance their research training,provide research platform,and to improve the incentive system.

Objective To learn the publications and influencing factors of scientific papers from nursing staff in China.Methods 750 authors were chosen in a stratified random sampling for survey,and the questionnaires included a survey form on nursing research papers publications and one research ability self-rating scalce Results The nursing staff surveyed published 1-70 papers per person,averaging 8.83papers per person; on average 0.45 papers were published per person per year.Main factors for research outputs range from high to low as follows:age,academic titles,research ability,education background and research training,with the Beta values of 0.255,0.234,0.142,0.093,and 0.087 respectively.Conclusion Nursing administrators need to develop respective objectives for nursing staff of different age,academic titles,education background and research ability,and set up an effective incentive mechanism to ignite the enthusiasm of scientific research.

Objective: To systematically evaluate the incidence and influencing factors of depression in family caregivers of Alzheimer's disease (AD) patients, so as to provide the basis for the prevention and treatment of depression among the family caregivers of AD patients. Methods: Publications pertaining to depression in family caregivers of AD patients were retrieved from CNKI, Wanfang Data, PubMed and other databases from the time of their establishment to June 15, 2023. The evaluation criteria recommended by the Agency for Healthcare Research and Quality (AHRQ) and the Newcastle-Ottawa Scale were used to assess the quality of cross-sectional and cohort studies, respectively. Stata 16.0 and Revman 5.4 softwares were used to conduct a meta-analysis on the incidence and influencing factors of depression in family caregivers of AD patients. Sensitivity analysis and publication bias assessment were also performed on the results. Results: A total of 2 324 articles were retrieved, and ultimately 14 articles were included, with a total sample size of 8 313 individuals. There were 6 high-quality articles and 8 moderate-quality articles. Meta-analysis showed that the incidence of depression in family caregivers of AD patients was 37.5% (95%CI: 30.2%-45.1%). Factors associated with depression included patients' high degree of dementia (OR=1.718, 95%CI: 1.059-2.789), patients' low scores on Activities of Daily Living Scale (OR=1.344, 95%CI: 1.059-1.706), patients' psychobehavioral abnormalities (OR=1.248, 95%CI: 1.155-1.348), long duration of caregiving (OR=1.998, 95%CI: 1.637-2.437), less involvement of other family members in caregiving (OR=1.597, 95%CI: 1.237-2.061), low educational level (OR=1.191, 95%CI: 1.044-1.359), poor caregiving skills (OR=3.060, 95%CI: 2.257-4.149), poor self-rated health (OR=2.536, 95%CI: 1.114-5.771) and social support (OR=0.424, 95%CI: 0.232-0.774). The results of depression incidence demonstrated good stability with no significant publication bias. However, publication bias was observed in the influencing factors for depression, which were patients' high degree of dementia and patients' low scores on Activities of Daily Living Scale. Conclusions The incidence of depression in family caregivers of AD patients ranges from 30.2% to 45.1%. It is primarily influenced by the severity of patients' symptoms and ability to perform daily activities, and caregivers' educational level, caregiving skills, health status, caregiving duration and social support.

Objective:To summarize the clinical manifestations, electrophysiological, muscle magnetic resonance imaging (MRI), pathological, and genetic characteristics of 8 patients with Emery-Dreifuss muscular dystrophy (EDMD) to improve the recognition and diagnosis of EDMD.Methods:Eight patients with EDMD confirmed by gene analysis admitted to Hebei Medical University Third Hospital from 2011 to 2022 were enrolled. The detailed clinical symptoms, neurophysiological examination, electrophysiological changes (electromyography and electrocardiography), skeletal muscle MRI characters, skeletal muscle pathological features and gene mutations were analyzed retrospectively.Results:The age of onset ranged from 2.0 to 6.0 (3.6±1.2) years. All patients had insidious onset and progressive development. Muscle weakness was the first symptom for 7 cases that manifested as difficulty in squatting and walking up stairs. Later, spinal ankylosis and joint contracture occurred. One patient had scoliosis as the first symptoms. Abnormal electrocardiogram was found in 4 cases. The electromyography of all patients showed myogenic damage. Muscle biopsy demonstrated dystrophic features in 1 patient, and other myopathic features, including a variation in muscle fiber size, a marked increase in internal nuclei, and, smaller diameter of typeⅠfibers. Next-generation sequencing result showed that 6/8 cases carried 4 LMNA heterozygous mutations (c.1583C>G, c.1357C>T, c.148C>T, c.1336A>G); 1/8 case carried EMD hemizygous mutation (c.501C>G); 1/8 carried SYNE1 heterozygous mutation (c.4364G>A). Conclusions:EDMD has highly clinical and genetical heterogeneity. The onset age is usually in childhood. The first symptom is characterized by weakness of lower limbs and abnormal walking posture. Electromyography shows myogenic lesion. Skeletal muscle MRI shows selective fat infiltrations. Muscle biopsy pathology lacks characteristic pathological findings. It is difficult to make diagnosis and differential diagnosis by clinical manifestations and auxiliary examination in the early stage of the disease. The second generation sequencing technology can improve the early diagnosis rate of EDMD.
