Objective:To explore the latent categories of sleep quality in shift nurses using latent profile analysis, and analyze the characteristics and influencing factors of each category.Methods:A convenience sampling method was used to select 1 480 shift nurses from three ClassⅢ Grade A hospitals in Fuyang city from January to February 2024. Data were collected using a general information questionnaire, Pittsburgh Sleep Quality Index, Perceived Stress Scale, and the Morningness-Eveningness Questionnaire-5. Latent profile analysis was performed to identify the latent categories of sleep quality, and multivariate logistic regression analysis was used to explore the influencing factors of different sleep quality categories. In this study, a total of 1 480 questionnaires were distributed. After excluding 28 invalid questionnaires, 1 452 valid questionnaires were retrieved, the effective recovery rate of the questionnaires was 98.11%.Results:The sleep quality of 1 452 shift nurses was classified into four latent categories: 44.5% (647/1 452) were in the "sleep impairment" category, 44.6% (648/1 452) in the "good sleep" category, 4.0% (58/1 452) in the "difficulty falling asleep-low efficiency" category, and 6.8% (99/1 452) in the "sleep disorder-medication-induced sleep" category. Multivariate logistic regression analysis revealed that perceived stress, monthly night shift frequency, sleep timing, daytime napping, and years of work experience were significant influencing factors for sleep quality ( P<0.05) . Conclusions:Sleep quality among shift nurses shows heterogeneity. Nursing managers should develop tailored management strategies and implement targeted sleep hygiene interventions based on nurses' sleep quality characteristics to improve their sleep quality.

Objective:To identify the development trajectories of self-neglect behavior in older adults and explore the associated influencing factors.Methods:A fixed cohort was constructed based on the data from three surveys of Chinese longitudinal healthy longevity survey (CLHLS) from 2011 to 2018. A total of eight variables from 4 dimensions including living environment, lifestyle, social interaction, and health care were selected to evaluate self-neglect. Group-based trajectory model was used to identify the development trajectory of self-neglect behavior in the older adults, and polynomial Logistic regression model was used to explore its influencing factors by Stata 16.1.Results:Finally, 2 754 older adults aged 60 and above were included.The development trajectory of self-neglect behavior in older adults, based on the group-based trajectory model, can be classified into stable-low group ( n=268, 9.7%), descending-moderate group ( n=2 224, 80.8%), and decreasing-high group ( n=262, 9.5%). Polynomial Logistic regression showed that, compared with stable-low group, living in rural areas ( B=1.116, OR=3.053, 95% CI= 2.278-4.091) and higher activities of daily living scores( B=0.137, OR=1.147, 95% CI=1.046-1.258) were the risk factors of descending-moderate group. Education levels with 1-6 years( B=-0.398, OR=0.672, 95% CI=0.469-0.963), >6 years( B=-1.072, OR=0.342, 95% CI=0.229-0.513), being married( B=-0.476, OR=0.621, 95% CI=0.444-0.870), self-reported good health( B=-0.808, OR=0.446, 95% CI= 0.213-0.932), improved health status( B=-0.704, OR=0.495, 95% CI=0.320-0.766), self-reported average economic status( B=-1.065, OR=0.345, 95% CI=0.148-0.802), self-reported good economic status( B=-1.634, OR=0.195, 95% CI=0.082-0.467), and a higher cognition score( B=-0.142, OR=0.867, 95% CI=0.798-0.942) served as protective factors of descending-moderate group. In addition to the above factors, being in the age group of 75-89 years( B=0.481, OR=1.617, 95% CI=1.057-2.473) was a risk factor for decreasing-high group compared to stable-low group. Conclusions:Three types of self-neglect behavior trajectories among older adults were identified in this study, suggesting that physical health and economy are the influencing factors of the development trajectory of self-neglect of the elderly.

OBJECTIVE To explore the effect of informationized closed-loop management in the consultation of over-dose narcotics. METHODS Since November 2021， the informationized consultation mode of over-dose narcotics had been established innovatively in our hospital on the basis of the previous process of over-dose narcotics use； the consultation mode of over-dose narcotics transformed from paper to information. The standardized rate of consultation for over-dose narcotics， the waiting time of consultation for patients using over-dose narcotics were compared before （from January to April 2021） and after the improvement （from November 2021 to February 2022）. RESULTS The informationized closed-loop management of over-dose narcotics consultation in our hospital was realized by improving hospital information system （maintaining basic information， embedding relevant reminder and consultation modules， and establishing query and statistics functions） and introducing mobile terminal. After establishing the mode， the standardized rate of the consultation increased from 55.56% to 93.75%； the waiting time for consultation was shortened from （20.61±9.77） min to （5.87±2.45） min. CONCLUSIONS The informationized closed-loop management can effectively improve the standardization rate of consultations for over-dose narcotics and reduce the waiting time for consultation for patients using over-dose narcotics.

Objective:To explore the application effect of four-track teaching mode (LBL: lecture-based learning; CBL: case-based learning; PBL: problem-based learning) in pediatric teaching of integrated traditional Chinese and Western Medicine.Methods:175 integrated traditional Chinese and Western medical students in seven-year program were divided into experimental group and control group. The experimental group was taught by four-track teaching mode, while students in the control group. Were applied with traditional teaching method ("LBL+CBL").Results:Students in the experimental group highly rated the four-track teaching mode and were better than those in the control group in the following aspects: satisfaction with teaching methods, interest in learning, the ability of creative thinking, the thinking ability of clinical diagnosis and treatment, and memorization ( P<0.05). And students' mid-term, final and comprehensive scores in the experimental group were significantly higher than those in the control group ( P<0.05). Conclusion:Compared with traditional teaching methods, the four-track teaching mode can improve the quality of pediatric teaching of integrated traditional Chinese and Western medical students, which should be further integrated and perfected in the teaching practice.

Objective To observe the effect of Kechuanning Oral liquid on the expression of P13K in CD4+and CD8+T cells of asthma rats induced by respiratory syncytial virus (RSV), and explore its mechanism of preventing and treating asthma induced by virus. Methods SD rats were randomly divided into phosphate-buffered saline (PBS) control group, model group, dexamethasone and salbutamol group (positive drug group), and Kechuanning oral liquid group. Ovalbumin asthma rats model was built and induced by RSV. CD4+and CD8+T cells were separated by magnetic beads method. The expressive level of PI3K-110αin T cells was detected by immumofluorescence method with flow cytometry. Results Compared with PBS control group, positive drug group and Kechuanning oral liquid group, the CD4+and CD8+T cells percentage and the expression level of PI3K-110α in CD4+ and CD8+T cells of model group were significantly higher. The differences were statistically significant (P<0.01). The CD4+and CD8+T cells percentage was not associated with the expression level of PI3K-110α in CD4+ and CD8+T cells of each group by Pearson correlation analysis. Conclusion The CD4+ and CD8+T cells involve in the asthma immunity balanced modulation, and the level of PI3K expressed by CD4+ and CD8+T cells increase distinctly. Kechuanning oral liquid can restrain the expression of PI3K in CD4+ and CD8+T cells, which might be one of the immunologic mechanisms of treating asthma.
