Objective To construct and validate a risk predictive model for treatment delay of patients with lung cancer. Methods A convenience sampling method was used to select 493 lung cancer patients admitted to a tertiary care hospital in Guangxi from September 2021 to June 2022. They were randomly divided into 345 cases in a modeling group and 148 cases in an internal validation group，and 47 lung cancer patients admitted to another tertiary care hospital were selected as the external validation group. The risk prediction model and nomograms model were constructed using logistic regression analysis and R software，and the area under the receiver operating characteristic（ROC） curve was used to test the prediction effect of the model. Results The established model was Y=e^z/（1+e^z），Z=9.04 × low level of disease perception + 2.01 × irregular physical examination-0.08 × perceived social support scale score + 0.23 × score of perceived barriers to healthcare-seeking decision-Chinese -0.15 × score of Health Literacy Scale for Chronic Patients. The ROC of the internal validation group was 0.849；the sensitivity was 82.39%；the specificity was 78.83%；the positive predictive was 90.61%；the negative predictive was 63.57%. The ROC of the external validation group was 0.830；the sensitivity was 97.36%；the specificity was 80.03%；the positive predictive was 94.62%；the negative predictive was 80.05%. Conclusion The low level of disease perception，lack of regular physical examination，the low level of social support，the high impaired perception of medical seeking behavior，and the low level of health literacy are the influencing factors of treatment delay of lung cancer patients，and the prediction model based on the above factors has a good degree of differentiation and calibration，which can help to identify the high-risk treatment delay lung cancer individuals. Nurses can identify high-risk groups based on this model，so as to take measures to improve their medical behavior and reduce the risk of treatment delay.

This study summarized the experience in caring pediatric pyrrolizidine alkaloid-associated hepatic sinusoidal obstruction syndrome after being treated with a transjugular intrahepatic portosystemic shunt（TIPS）. The key points of before-surgery care include timely implementation of anticoagulant therapy and ensuring the safety of medication administration；dynamic monitoring of disease changes and applying scientific management of ascites. The key points of post-surgery care include solidifying sheath care to maintain catheter function；enhancing monitoring of the patient’s condition and medication instruction to prevent hepatic encephalopathy and intra-stent thrombosis；correcting assessment of nutritional status and formulation of nutritional support programs；conducting health education and establishing a multi-platform follow-up model. After 2 months of careful treatment and nursing，the child made a good recovery at the 6-month follow-up.

Objective To conduct a scoping review of studies on cognitive training interventions for patients with cognitive impairment based on digital technology to identify digital technology，content elements and outcome indicators of cognitive training and to provide guidance for future research. Methods A literature search was performed in the PubMed，Embase，CINAHL，Web of Science，Scopus，Cochrane Library，PsycINFO，CNKI，Wanfang，and CMB databases to identify relevant studies. The search period is from the establishment of databases to November 18，2022. The included studies were summarized and analyzed. Results A total of 19 articles were included，and the digital technology-based cognitive training digital technology included computer technology，virtual reality technology，intelligent robotics，and mixed reality technology. The cognitive training content covered attention，memory，language skills，abstract thinking skills，executive skills，visuospatial orientation，motor balance，logic and computational skills，and daily life skills training. The outcome indicators involve 2 aspects of overall cognitive function and each cognitive function. Conclusion The digital technology-based cognitive training can motivate patients with cognitive impairment to participate and significantly improve their cognitive function. In the future，the use of artificial intelligence technology can be explored to optimize nursing human resources allocation and cultivate specialized nurses of digital technology cognitive training information.

Objective To translate and revise Hand Hygiene Behaviour Questionnaire（HHBQ） based on COM-B （capability,opportunity,motivation-behaviour） model,and to test its reliability and validity. Methods According to the intercultural debugging guidelines,the Chinese version of HHBQ was prepared by pre-translation,pre-translation synthesis,back-translation,back-translation synthesis,original author review,expert consultation and pre-test. The reliability and validity of Chinese version of HHBQ were evaluated by a survey of 537 medical staff from 3 tertiary A hospitals in Hangzhou from July to October 2021. Results The Chinese version of HHBQ contained 3 dimensions,namely,hand hygiene ability（5 items）,hand hygiene opportunity（7 items）,and hand hygiene motivation （5 items）. The content validity of the total scale was 0.995,and the content validity of each item in the questionnaire was 0.923~1.000. 3 common factors were extracted from exploratory factor analysis,and the cumulative variance contribution rate was 68.741%. Confirmatory factor analysis showed that the model fit well. The Cronbach’s α coefficients of the total amount table are 0.918,and the Cronbach’s α coefficients of each dimension are 0.871~0.906. The retest reliability of the questionnaire was 0.739. Conclusion The Chinese version of HHBQ has good reliability and validity,and it can be used to comprehensively evaluate the influencing factors of medical staff’s hand hygiene.

Objective To develop the management information system of recognition and prevention of flap vascular crisis,and to explore its application effect in the prevention and nursing management of the vascular crisis in patients with flap transplantation. Methods A research group of flap vascular crisis was established to construct the management information system of flap vascular crisis identification and prevention and control. The man-machine interaction technology was used to develop 5 modules,including addition of patient and basic information,flap labeling,flap observation,early warning of crisis,and nursing documents. It was officially put into clinical application in December 2019. The incidence of timely detection rate of vascular crisis,the incidence of vascular crisis,and survival rate of flap were compared before and after the application of the system. The satisfaction of medical staff was investigated. Results After the application of the information system,the timely detection rate of vascular crisis increased from 33.33% to 92.31%（P=0.007）;the incidence of vascular crisis increased from 8.18% to 10.24%（P=0.587）;the survival rate of flap increased from 94.55% to 99.21%（P=0.083）. Conclusion The interface of management information system for the recognition and prevention of flap vascular crisis is simple and easy to operate. It can provide nurses with accurate and objective decision-making basis,improve the timely detection rate of vascular crisis,and help to further ensure patient safety.

Objective To explore the influencing factors and coping strategies of pulmonary rehabilitation barriers in patients with chronic obstructive pulmonary disease（COPD）. Methods Objective sampling and theoretical sampling were used to select 9 patients with COPD,8 doctors and 7 nurses for semi-structured interviews from June,2016 to June,2017,and the data was analyzed by three-level coding of the grounded theory. Results The influencing factors of pulmonary rehabilitation barriers in patients with COPD included individual factors,family factors and pulmonary rehabilitation environment. The coping strategies of pulmonary rehabilitation barriers in patients with COPD included incentives,safety assurance,cooperation in pulmonary rehabilitation and promotion of pulmonary rehabilitation concept. Conclusion Coping with pulmonary rehabilitation barriers is one of the inevitable challenges to promote chronic disease management. Further identification of influencing factors of pulmonary rehabilitation and the proposal of coping strategies for pulmonary rehabilitation obstacles will provide references for the formulation and implementation of pulmonary rehabilitation plans for patients with COPD.
