摘要： Topological nodal rings as the simplest topological nodal lines recently have been extensively studied in optical lattices. However, the realization of complex nodal line structures like nodal chains in this system remains a crucial challenge. Here we propose an experimental scheme to realize and detect topological nodal chains in optical Raman lattices. Specifically, we construct a three-dimensional optical Raman lattice which supports next nearest-neighbor spin-orbit couplings and hosts topological nodal chains in its energy spectra. Interestingly, the realized nodal chains are protected by mirror symmetry and could be tuned into a large variety of shapes, including the inner and outer nodal chains. We also demonstrate that the shapes of the nodal chains could be detected by measuring spin polarizations. Our study opens up the possibility of exploring topological nodal-chain semimetal phases in optical lattices.

摘要： The current status of rehabilitation exercise KAP and exercise fear in patients after percutaneous coronary intervention was understood, and the correlation between the two was analyzed. Methods: A general information questionnaire, an exercise fear scale for cardiac patients and a rehabilitation exercise KAP questionnaire for patients with coronary artery disease were used in a cross-sectional survey of 326 patients undergoing percutaneous coronary intervention in the cardiology department of a tertiary care hospital in Luoyang from April to August 2020. correlations. Results: The total rehabilitation exercise KAP score of the 326 patients after percutaneous coronary intervention was (49.52 9.85), which included a score of (10.46 5.99) on the knowledge dimension, (18.52 2.90) on the belief dimension and (20.53 3.47) on the behavioral dimension. The total score for fear of movement was (39.934.56), which included (10.631.76) for the avoidance dimension, (10.781.59) for the fear of movement dimension, (8.341.36) for the perception of danger and (10.191.76) for the dysfunctional dimension. The results of the Pearson correlation analysis showed that the patient's total KAP score and the scores on each dimension of rehabilitation exercise were mostly negatively correlated with the total score and the scores on each dimension of fear of exercise (p0.05). Conclusion: Patients undergoing percutaneous coronary intervention have higher levels of fear of exercise, lower levels of perception of rehabilitation exercise, and attitudes and actions towards exercise that need to be improved. Exercise fear was negatively correlated with KAP levels for rehabilitation exercise. Health care professionals should improve their knowledge of rehabilitation exercises to help patients develop a positive attitude towards rehabilitation exercises, so that patients' fear of exercise can be reduced and early postoperative rehabilitation exercises can be promoted.

摘要： AbstractBackground The growth of Chinese medicine nursing is gaining increasing attention as a result of the advancement of traditional medicine and the shifting public perceptions of health. Chinese medicine nursing talents are human resources that are essential to the field’s development. A significant challenge to the training of TCM nursing talent is raising the standard of clinical practice instruction. In this study, to improve the quality of TCM nursing instruction and advance the field of TCM nursing, we established a clinical practice plan based on the CDIO (Conceptualization-Design-Implementation-Operation) concept and implemented it in the province’s professional nurse training program.MethodsIn our hospital，32 nurses who took part inthe Jiangsu Provincial TCM Nursing Professional Nurse Training Programfrom August to September 2023 were selected. The clinical practice stage of the training was conducted utilizing the CDIO model. After the training, the practical operation, the dialectical nursing ability and autonomous learning ability were assessed. We also assessed how satisfied they were with the training.ResultsAfter the training, theclinical practice ability, dialectical nursingability, and autonomous learning abilitywere all significantly higher than they were previously (all PConclusionCDIO model can improved clinical practice ability, enhanced their capacity to provide nursing care according to syndrome differentiation, stimulate the independent learning ability, and increased satisfaction with training. Furthermore, it offers novel ideas, methods, and strategies for upcoming clinical practice training.
