Objective:To systematically evaluate and integrate the qualitative research of nursing students participating in hospice care practice experience, to provide a basis for the better development of hospice care education.Methods:A computer search was conducted on the China national knowledge infrastructure, Chinese Biomedical Literature Database, VIP database, Wanfang Medical Database, Cochrane Library, Embase, Web of Science, and PubMed for qualitative research on nursing students' participation in hospice care practices. The search period was from the establishment of the database to February 2023. The quality of the included literature was evaluated using the qualitative research quality evaluation criteria of the Australian JBI Evidence Based Health Care Center. A aggregative integration method was used for result integration.Results:A total of 16 articles were included, and 46 major research results were extracted and summarized into 9 new categories, forming 4 integrated results: providing hospice care services for patients and their families; emotional experience of nursing dying patients; coping with negative experience and harvesting personal growth; needs and difficulties.Conclusions:Nursing students experience multiple emotional experiences in hospice care practice, and are eager to help and support in various aspects. It is suggested for managers to pay attention to the inner experience and needs of nursing students, improve hospice care education in China, and improve the end-of-life care ability of nursing students.

Objective:To develop a double-set endotracheal intubation and evaluate its effectiveness.Methods:The development of a double-set endotracheal intubation was achieved by integrating endotracheal intubation with dental pads. From November 2023 to July 2024, convenience sampling was used to select 60 patients with endotracheal intubation admitted to the ICU of the First Hospital of Jiaxing as participants. Patients were divided into an experimental group ( n=30) and a control group ( n=30) using a random number table method. Experimental group was treated with a double-set endotracheal intubation, while control group was treated with a regular endotracheal intubation. The incidence of oral mucosal membrane pressure injury and oral ulcers during endotracheal intubation, the Chinese version of the modified Beck Oral Assessment score, plaque index, and endotracheal intubation duration were compared between two groups of ICU patients. Results:The duration of endotracheal intubation in experimental group was shorter than that in control group ( P<0.05), and the difference was statistically significant ( P<0.05). The number of cases with oral mucosal membrane pressure injury and oral ulcers in experimental group, as well as the Chinese version of the modified Beck Oral Assessment score, were lower than those in control group, and the differences were statistically significant ( P<0.05). There was no statistically significant difference in the plaque index between two groups ( P>0.05) . Conclusions:Double-set endotracheal intubation can effectively improve the efficiency of intubation in ICU patients, reduce the local pressure on oral tissues caused by intubation, improve the oral condition of patients, and have good clinical effects.

Objective:To systematically evaluate and integrate the qualitative research of the practical experience and practical difficulties of advance care planning (ACP), so as to provide a reference for subsequent clinical nurses to better carry out ACP.Methods:PubMed, Web of Science, Embase, Cochrane Library, CINAHL, CNKI, Wanfang, VIP, Chinese Biomedical Literature Database were collected the qualitative research on the practical experience and practical difficulties of nurses′advance care planing, and the search time was the database establishment until August 1, 2022. Literature quality evaluation was conducted by the Joanna Briggs Institute (JBI) (2016), and the results were summarized using Meta integration method.Results:A total of 13 studies were included, and 39 studies were summarized into 11 new categories, forming 4 integrated results: nurses′ cognition of ACP practice, emotional experience of nurses′ ACP practice, personal factors that hinder ACP practice, and external environmental factors that hinder ACP practice.Conclusions:In ACP practice, nurses should be actively guided to have positive cognitive and emotional experience to improve their competence in ACP practice. At the same time, government departments should be united to support, integrate hospitals, society and other forces to formulate coping strategies against obstacles, so as to promote the development and practice of ACP.

Objective:To evaluate the association between the eye exercises and one-year axial eye elongation in grade 7 students in Beijing.Methods:Sampling was performed using a multistage random cluster approach, and 1 443 students of grade 7 were selected from 9 middle schools in 6 districts for the baseline survey. Data were collected by questionnaires and axial length measurement. Multiple linear regression analysis was used to evaluate the association between eye exercises and excessive axial eye elongation.Results:Among 1 197 (82.95%) students with complete information, the median ( Q R) age was 12.00 (1.00) years old, girls accounted for 44.28%, and the median ( Q R) axial eye elongation was 0.22 (0.18) mm. In the multiple linear regression analysis, the frequency of eye exercises was significantly correlated with excessive axial eye elongation in boys ( β=-0.135, 95% CI:-0.253--0.018) but not in girls ( β=-0.075, 95% CI:-0.207- 0.058) after adjusting for sex, age, body height, the number of myopic parents, time spent outdoors and time spent on reading and writing outside class; while the seriousness of eye exercises was not significantly associated with axial eye elongation in boys ( β=-0.028, 95% CI: -0.114-0.058) and girls ( β=-0.035, 95% CI: -0.134-0.064). Conclusion:The increased frequency of eye exercises is beneficial to control the axial eye elongation in boys in Beijing.

Objective To measure the occupation-sex stereotype, studying value and emotional stability of undergraduate nursing students (male), so as to provide further reference for exploring approaches of weakening or eliminating occupation-sex stereotype on male nursing students.Methods From November 2015 to November 2016, with method of convenience sampling, 54 undergraduate male nursing students from Grade I, II and III, from School of Nursing, of Kunming Medical University, were selected and were measured by Implicit association test (IAT), Studying value doubt scale and Eysenck emotional stability test.Results There were 34 male nursing students whose results of D-algorithm >0.5; 73.08% of the male nursing students had intensity of implicit sex stereotype>200 ms; 40.74% of the undergraduate male nursing students considered studying at the university valueless; more than 85% of the undergraduate male nursing students experienced inferiority complex or depression; over 65% were with obsession, hypochondriasis or low autonomy; a few were with anxiety or delusion of sin.Conclusions Occupation-sex stereotype is common among male nursing students. Several of the male nursing students considered studying at the university valueless. Emotional problems exist, like inferiority complex, depression, obsession and hypochondriasis.

Objective To study the effects of diacylglycerol(DG)on body weight of rats and its possible metabolic mechanism. Method (1) SD rats (n=30) were randomly divided into 3 groups. They were given free access to diets containing 7% (wt) triacylglycerol (TG, control group), 20% (wt) TG or 20% (wt) DG diets, respectively for 8 w. The changes of body weight, height, food intake, and feces were recorded. At the end of experiment, abdominal fat weight (including perirenal fat and epididymal fat), blood lipids were detected. (2) 13 w male Wistar rats (n=50) were divided into 2 groups(administrated with 10% TG or DG emulsion, respectively)in postprandial blood fat profile experiment. Blood lipids of 5 rats were analyzed at desired interval. (3) 6 w male Wistar rats (n=30) were randomly divided into 3 group, control group, DG group and TG group, administrated with glucose solution, 20%DG emulsion and 20%TG emulsion respectively for 6 d. Urine in 144 hr was collected continuously and analyzed for total ketone bodies. Results High DG diet resulted in a significant reduction in both body weight gain, ratio of abdominal fat to body weight and serum TG levels compared with the high TG diet. DG group have higher FFA level in portal vein and lower TG level in jugular vein than those of high TG group. But urine ketone body level of high DG group was higher than high TG group. Conclusion Dietary DG reduced fat accumulation inabdominal region, body and blood, and these effects may be involved with different metabolic ways of DG compared with TG.

Objective To analyze the nutritional composition of lipids in silkworm chrysalis (Bombyx mori L.). Method Crude lipids were extracted by chloroform/methanol, and fatty acid, tocopherol, sterol and phospholipid composition in silkworm chrysalis were determined by GC, HPLC and TLC methods. Results Silkworm chrysalis was rich in lipid (32.79%) in which the most abundant fatty acids were C18:3 (32.79%), C18:1 (32.53%), C16:0 (22.42%), but C18:2 (4.37%), C18:0 (5.73%) and C16:1 (0.57%) were relatively less. The sterols included cholesterol (67.35%), ?-sitosterol (19.21%), and trace amount of campesterol (0.28%) and brassicasterol (0.30%). Total tocopherols detected were at an average concentration of 486 mg/kg, including ?-tocopherol (44.85%), ?(+ ? )-tocopherol (44.57%), and ?-tocopherol (10.85%). The phospholipid content was about 1.17mg/g, among which, phosphorylcholine about 41.8%. Conclusion Silkworm chrystalis (Bombyx mori L.) could be a good source of nutritional edible oil rich in unsaturated fatty acid, phospholipids, phytosterols and tocopherols, particularly ?-linolenic acid, ?-sistosterol and ?-tocopherol.
