Objective:This study aims to develop a scientific research ethics knowledge, attitude and practice questionnaire for clinical nurses, and to test its reliability and validity, providing evaluation tools for nursing managers to understand nurses' attitude and behaviors towards research ethics knowledge.Methods:With the knowledge, attitude and practice theory as the conceptual framework, combined with the semi-structured interview, an initial questionnaire was formed through Delphi expert letter inquiry and pre-survey. About 307 nurses from 7 hospitals in Shanxi, Yunnan and Jiangxi provinces were selected to investigate, and the reliability and validity test were conducted.Results:Finally, a questionnaire of 28 items was designed, including scientific research ethics knowledge, attitude and behavior. The overall Cronbach's α coefficient was 0.967, the overall half reliability was 0.884 8, the overall test reliability was 0.958, and the content validity index of scale level was 0.844. The exploratory factor analysis extracted 3 common factors, and the cumulative variance contribution rate was 74.150%.Conclusions:This questionnaire has good credit validity and can be used as an objective tool to evaluate the level of ethical knowledge and practice of clinical nurses.

Acute lung injury is an acute and criti-cal respiratory disease with complex pathogenesis,which has a high incidence rate and high mortality.At present,acute lung injury is mainly treated by mechanical ventilation,glucocorticoid anti-inflam-matory and extracorporeal membrane oxygen-ation.Traditional Chinese medicine also shows great potential in improving the clinical manifesta-tions and prognosis of patients.Quercetin is a fla-vonol compound,which can prevent and treat acute lung injury by anti-inflammatory,anti-oxida-tive stress,regulating programmed cell death,anti-bacterial and antiviral.This article summarizes the mechanism of action and research progress of quercetin in the treatment of acute lung injury,aiming to provide reference for subsequent re-search and clinical applications.

Dysfunction of the diaphragm is a common problem in mechanically ventilated patients and is closely related to various adverse outcomes.This review summarizes the evaluation methods of diaphragm function,the association between diaphragm dysfunction and adverse clinical outcomes in critically ill mechanically ventilated patients,and the protective effect of diaphragm function on adverse outcomes related to mechanical ventilation.The aim is to provide references for medical staff to optimize evaluation techniques,develop personalized nursing plans,and improve patients' quality of life and health outcomes.

Objective:To explore the current status and influencing factors of fatigue in patients with Cushing syndrome in China, so as to provide a basis for clinical interventions.Methods:Convenience sampling was used to select 260 inpatients with Cushing syndrome who met the inclusion and exclusion criteria in 9 ClassⅢ Grade A hospitals within the 7 geographic subregions of China from February to April 2023 for the study. General Information Questionnaire, the Chinese version of the Multidimensional Fatigue Inventory-20, Barthel Index, and Self-Rating Depression Scale were used for the survey.Results:A total of 260 questionnaires were distributed and 241 valid questionnaires were recovered, with an effective recovery rate of 92.7% (241/260). The MFI-20 score of 241 patients with Cushing syndrome was 58.00 (46.00, 64.00). 65.1% (157/241) of patients with Cushing syndrome suffered from fatigue, and 73.2% (115/157) of patients with fatigue exhibited multidimensional fatigue. Univariate analysis showed that there were statistically significant differences in fatigue scores among patients with Cushing syndrome with different cultural levels, recurrence frequency, activity of daily living, hypertension, and depression ( P<0.05). Multiple linear regression analysis showed that depression was a risk factor for fatigue in patients with Cushing syndrome, and the difference was statistically significant ( P<0.05) . Conclusions:Fatigue in patients with Cushing syndrome needs attention. Medical and nursing staff should pay close attention to the psychological status of patients with Cushing syndrome, encourage them to actively cope, alleviate their depression, in order to improve their fatigue.

Objective:To explore the latent profile characteristics of cancer-related fatigue (CRF) in breast cancer patients during the rehabilitation phase and to analyze the influencing factors of different latent profiles.Methods:A convenience sampling method was used to recruit 190 breast cancer patients in the rehabilitation phase from the follow-up cohort at Peking Union Medical College Hospital between March and May 2024. Data was collected using a general information questionnaire, the Cancer Fatigue Scale, the Self-Rating Anxiety Scale, the Self-Rating Depression Scale, the Pittsburgh Sleep Quality Index and the Visual Analogue Scale. Logistic regression analysis was conducted to identify the influencing factors of CRF latent profiles. A total of 190 questionnaires were distributed, and 183 valid responses were collected, yielding an effective response rate of 96.32% (183/190) .Results:Three latent profiles of CRF were identified: mild fatigue, moderate fatigue, and severe fatigue. Menopausal status, depressive symptoms, and pain scores were significant influencing factors of the CRF latent profiles ( P<0.05) . Conclusions:Cancer-related fatigue in breast cancer patients during the rehabilitation phase exhibits distinct latent profile characteristics. Early identification of profile types and associated influencing factors may provide a scientific basis for healthcare professionals to develop targeted clinical interventions to help patients alleviate fatigue.

Central venous pressure(CVP)is a commonly used hemodynamic index in clinical practice,and the accuracy of its measurement results is influenced by the measurement technical specifications.Based on research evidence and clinical practice,this article interprets the main content of the group standard of CVP measurement technology,and proposes suggestions for its use.It aims to guide clinical nursing staff to correctly understand the principles and methods of CVP measurement,and promote the standardization of nursing practice and the accuracy of measurement results.
