Objective To explore the effect of finger exercises and cognitive training on cognitive function, ability of daily living and quality of life of elderly patients with mild cognitive impairment. Methods About 90 elderly patients with mild cognitive impairment were randomly divided into experimental group and control group. In the experimental group finger exercises and cognitive training were implemented, and the control group was given routine care and health education. 3 months and 6 months after the intervention, the two groups were compared in respect of the cognitive function, ability of daily living and quality of life. Results The difference of cognitive function, daily living ability and quality of life in the elderly were statistically significant between the two groups 3 month and 6 month after the intervention (P<0.05). Pairwise comparison done at three time points (before intervention, 3 months and 6 months after intervention) in the experimental group showed that the difference of cognitive function, daily living ability and quality of life in the elderly were statistically significant between before intervention and 3 months after intervention, before intervention and 6 months after intervention. Conclusion The finger exercises and cognitive training in elderly patients with mild cognitive impairment can effectively strengthen the cognitive function and ability of daily living, and improve the quality of life.

Experiential teaching is a practical, reflective, and situational teaching method. Based on the systematic review of literature published worldwide, this paper summarizes the characteristics and organizational forms of experiential teaching, with a focus on its current application and existing problems in teaching geriatric nursing. This review provides suggestions for the reform of teaching methods of geriatric nursing in China.

Objective:To systematically evaluate the dose-response relationships of resistance exercise intensity in frail elderly.Methods:A comprehensive search of randomized controlled trials on the dose-response relationships of resistance exercise for frail elderly in PubMed, Embase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Database. The documents that met the conditions were screened out, and after the data were extracted and the quality of the documents were evaluated, the RevMan 5.3 software was used for Meta analysis.Results:A total of 10 eligible randomized controlled trials were included in this study. The subjects of the study were 454 cases of frail and pre-frail elderly. After Meta analysis, there was a dose-response relationships between the training intensity of resistance exercise and the muscle strength, muscle endurance, and physical function of frail elderly. Both low-intensity and high-intensity resistance exercises can significantly increase the leg muscle strength of frail elderly people ( MD=4.58, 95% CI 3.34-5.82, P<0.05) and muscle endurance ( MD=12.27, 95% CI 6.54-17.99, P<0.05). Compared with low-intensity resistance exercise, high-intensity resistance exercise increased leg muscle strength of frail elderly people ( MD=7.97, 95% CI 0.85-15.09, P<0.05) and muscle endurance ( MD=6.94, 95% CI 5.21-8.66, P<0.05) showed more obvious advantages. The analysis of the results of the chair sitting test and the stairs climbing test shows that low-intensity resistance exercise has no obvious advantage in improving the physical function of frail elderly people, while high-intensity resistance exercise can significantly improve the physical function of frail elderly people ( MD=-5.8, 95% CI -7.3--4.29, P<0.05; MD=-1.20, 95% CI-2.17--0.23, P<0.05). Conclusions:Resistance exercise can significantly improve the muscle strength, muscle endurance and physical function of the frail elderly. High-intensity resistance exercise is more effective than low-intensity resistance exercise.

Formulating codes of ethics for nurses are not only the need of establishing nurses’ professional image and dignity, but also the demand of nursing discipline development. By combing the relevant documents of codes of ethics for nurses at home and abroad, this paper summarized the main contents and application of codes of ethics for nurses, found that codes of ethics for nurses were based on the basic principle of "patient-oriented", discussing the relationship between nurses and patients, collaborators, environment, society, specialty and personal development, and forming the constraint standard for nurses’ behavior in combination with the expectation of local cultural values for nursing industry. The codes of ethics for nurses in China need to further clarify the scope of nursing, formulate behavioral norms in various specialties, and through clinical evaluation, education, management and other aspects to promote its popularization and implementation.
