Objective To observe the clinical and imaging features of invasive Klebsiella pneumoniae liver abscess syndrome(IKPLAS).Methods Data of 68 patients with Klebsiella pneumoniae liver abscess(KPLA)were retrospectively analyzed.The patients were divided into IKPLAS group(n=25)or non-IKPLAS group(n=43)according to extrahepatic invasive infection or not.Clinical data as well as CT and/or MRI findings were compared between groups.Results The patients'age was lower,while glycated hemoglobin and D-dimer levels were higher in IKPLAS group than those in non-IKPLAS group(all P＜0.05).Hepatic venous thrombophlebitis was detected in 18 cases in IKPLAS group and 6 cases in non-IKPLAS group,while arterial phase abnormal high perfusion around abscess was noticed in 10 cases in IKPLAS group and 28 cases in non-IKPLAS group,both being significantly different between groups(both P＜0.05).The extrahepatic infection in IKPLAS group mainly observed in lungs(19/25,76.00%).Conclusion The ages were lower,while glycated hemoglobin and D-dimer levels were both higher in IKPLAS than in the other KPLA patients.Often appeared hepatic venous thrombophlebitis and extrahepatic infection mainly affecting lungs were imaging characteristics of IKPLAS.

Objective:To analyze the correlation between the grouping and weighting of two sets of disease combination systems, namely diagnosis-related groups(DRG) and diagnosis-intervention packet(DIP), and to establish a multidimensional analysis and evaluation mode by applying DRG, DIP, and clinical pathway to guide the standardized diagnosis and treatment and management of disease types.Methods:DRG grouping and DIP simulation full enrollment were applied to patients discharged from a tertiary Grade A general hospital in 2019. The correlation analysis between DRG, DIP, and clinical pathway inclusion(entry), correlation analysis between relative weight of DRG group and DIP standard score, and correlation analysis between clinical pathway entry and cost structure of the two disease groups were conducted by using chi-square test, Pearson correlation analysis, t-test, structural change value, degree of structural change, and incremental contribution rate. Results:Among the 130 395 patients, 41 460 cases entered the clinical pathway, 127 535 cases were enrolled in DRG, and 104 227 cases were enrolled in DIP. There was a correlation between the enrollment of DRG, DIP, and clinical pathway( P<0.05), and there was also a correlation between the relative weight of DRG groups and the enrollment of clinical pathway. The relative weight of the DRG disease group was positively correlated with the DIP standard score( r2=0.761 7, P<0.001). There was a significant difference in hospitalization costs between patients with and without clinical pathway access for some diseases( P<0.05), and different cost categories had different impacts on the total costs. Conclusions:The weight assignment and value orientation of DRG and DIP disease types are consistent, and the multi-dimensional fusion evaluation mode for DRG-DIP-clinical pathway is feasible. The correlation analysis of DRG, DIP, and clinical pathways can serve as the basis for disease classification and cost structure evaluation, which could help to carry out hospital′s refined management and optimize disease structure.

BackgroundThe existing tools in China for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint do not sufficiently consider the specialty in psychiatric practice， and the scale items are somewhat cumbersome to use， which together restrict their further promotion and application. Accordingly， there is an urgent need for developing a more scientific assessment tool. ObjectiveTo construct a scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint and to verify its reliability and validity， so as to provide a generic tool for the assessment. MethodsBased on the theoretical framework of the knowledge-attitude-practice model， the preliminary scale was formed through systematic literature review， qualitative interview and Delphi method. From July to December 2021， a stratified sampling was utilized to select 729 psychiatric nurses from tertiary， secondary and primary （including unclassified medical institutions and grassroots hospitals） psychiatric hospitals in Guangdong Province. The formal scale was developed through item analysis， exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated by content validity and structure validity， and the reliability was verified by procedures including Cronbach's α coefficient， test-retest reliability， and split-half reliability. ResultsA total of 12 items of three dimensions （knowledge， attitude， practice） were included in the scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. The scale-level content validity index （S-CVI） was 0.941， and the item-level content validity index （I-CVI） ranged from 0.812 to 1.000. Exploratory factor analysis extracted three common factors， and the cumulative variance contribution rate was 62.948%. The confirmatory factor yielded adequate fit. Cronbach's α coefficient was found to be 0.887 for the scale， 0.819 for knowledge dimension， 0.842 for attitude dimension， and 0.831 for practice dimension. The split-half reliability and test-retest reliability for the scale were 0.712 and 0.922， respectively. ConclusionThe scale shows satisfactory reliability and validity， which can be used to assess psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. ［Funded by Guangdong Clinical Teaching Base Teaching Reform Research Project （number， 2021JD119）］

Objective To explore the current situation of evidence-based nursing practice in pain assess-ment by nurses in China to provide the decision-making data for maximizing to relieve the patient pain by car-rying out the pain assessment evidence-based nursing practice.Methods The non-probability sampling meth-od was used to conduct an online anonymous survey in 63 class 3A hospitals in the whole country.The ques-tionnaire included the general information questionnaire and evidence-based nursing practice scale for pain as-sessment.The evidence-based nursing practice scale for pain assessment included the pain screening,compre-hensive pain assessment,exchange with the patients and their households in the pain assessment,pain re-as-sessment,pain assessment tool selection and record.The 5 dimensions were compared by using item equaliza-tion.The data analysis was performed by the SPSS26.0.Results A total of 1 518 questionnaires were recov-ered,in which 1 482 questionnaires were valid with an effective recovery rate of 97.62％.The evidence-based nurse practice of pain assessment by nurse was(108.40±17.96)points,the pain screening was(12.87±2.23)points,the item average score was the highest[(4.29±0.74)points],the communication with the patients and their household was(23.69±4.93)points and the item average score was the lowest[(3.94±0.82)points].The regression analysis showed that whether receiving the pain training and whether distinguishing active pain and resting pain had a positive effect on the practical behavior(P＜0.05).Conclusion The evi-dence-based nursing practice in pain assessment by nurses in the partial class 3A hospitals in China is in the upper medium level.However,the communication between the patients and their families is insufficient.Man-agers should constantly enrich the training content and methods,and guide nurses to strengthen the communi-cation between nurses and the patients.

This paper introduces the concept, basic theory and interventions of reminiscence therapy, summarizes the application status of reminiscence therapy in elderly patients with mental disorders and puts forward the prospect, so as to provide reference for research in China.

This paper analyzed the research status of living wills at home and abroad from three aspects: the status of living wills knowledge-attitude-practice, the influencing factors of the living wills development, and the effects of living wills. It also provided some suggestions for promoting the development of living wills in China. In foreign countries, a large number of quantitative and qualitative studies have been carried out in this regard, and the research contents were relatively in-depth. However, China initiated late in this field, and the research contents and methods were relatively simple. Living wills not only protect patients’ decision-making right, but also promote the rational distribution of medical resources, as well as ensure the fairness of health services. For China, with a large population and uneven distribution of health resources, living wills have broad implementation prospects.

Objective:To evaluate the correlation of active inflammatory changes of the symphysis pubis on magnetic resonance imaging (MRI) scans with clinical factors in patients with axial spondyloarthritis.Methods:We retrospectively evaluated 112 patients with axial spondyloarthritis (ax-SpA) in our hospital from February 2014 to November 2020. Patients were divided into 4 groups: symphysis pubis + sacroiliac arthritis, symphysis pubis + non-sacroiliac arthritis, non-symphysis pubis + sacroiliac arthritis, and non symphysis pubis + non-sacroiliac arthritis group. Intra-group correlation coefficient ( ICC) was used to analyze the correlation between MRI active inflammation of the symphysis pubis and the sacroilioarthritis. Age, sex, symptom duration, smoking, body mass index, human leukocyte antigen (HLA)-B27 positive rate, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) among the four groups were compared by one-way analysis of variance (ANOVA) and Chi-square test. Results:The proportion of active inflammation of the symphysis pubis was 35.7% (40/112). There was no correlation between active inflammation of the symphysis pubis and sacroilioarthritis ( r=-0.06, P=0.559). Twenty-four patients of the 69 patients with sacroilioarthritis had active inflammation of the symphysis pubis, 16 patients of the 43 patients without sacroilioarthritis had active inflammation of the symphysis pubis. In patients without active inflammation of the sacroiliac joint, the CRP and ESR of the active inflammation of the symphysis pubis group was (49±60) mg/L, (40±19) mm/1 h, statistically higher than that of the non-active inflammation group (19±22) mg/L, (22±37) mm/1 h ( t=2.36, P=0.023; t=2.88, P=0.006). In patients who had active inflammation of the symphysis pubis, the symptom duration of the non-active inflammation of the sacroiliac joint, was (14±9) years, which was significantly longer than that of the active inflammation group (5±4) years ( t=4.07, P=0.001). Conclusion:There is no correlation between active inflammatory changes of the symphysis pubis and bone marrow edema of the sacroiliac joint. Therefore, in ax-SpA patients with inflammatory low back pain and/or hip/groin pain, and also with high levels of CRP, ESR, but no active inflammatory changes of the sacroiliac joint on MRI scans, active inflammation of the symphysis pubis should be considered.

Objective:To review and analyze the clinical experience of children with aortic valve stenosis and/or insufficiency treated with autologous pulmonary valve for aortic valve replacement procedure(Ross operation) with ePTFE artificial valve for right ventricular outflow tract reconstruction.Methods:From 2015 to 2020, 8 cases of aortic stenosis and/or aortic insufficiency treated by Ross operation in our center were collected, with an age of 0.5-13.2 years old. 4 cases of aortic stenosis were diagnosed preoperatively, 3 cases of aortic stenosis with aortic insufficiency, and 1 case of infective endocarditis involving the aortic valve. The operation was carried out in three steps: Harvest autologous pulmonary valve; the diseased aortic valve was resected and autologous pulmonary valve was transplanted to the aorta by aortic root transplantation; the right ventricular outflow tract was reconstructed by a handmade ePTFE artificial flap blood vessel.Results:In 6 cases, the right ventricular outflow tract was reconstructed by hand-sewn ePTFE trileaflets, and artificial univalve in 2 cases, no death occurred during operation; all patients were cured and discharged. The patients were followed up for 1 to 36 months, with mean of(12.63±12.19) months. There was no long-term death or valvular complications. During follow-up echocardiography indicated 1 case of moderate aortic regurgitation, 1 case of mild-moderate regurgitation, and moderate regurgitation was found in 2 patients with artificial single pulmonary valve. For the remaining patients, they were mild aortic regurgitation, and a trivial or mild pulmonary artery regurgitation with hand-sewn three-leaflets ePTFE artificial vessel; All patients were followed up at the last time with a peak pressure of(6.63±3.46) mmHg(1 mmHg=0.133 kPa) across the aortic valve. The left ventricular outflow tract and aortic annulus shrank slightly after surgery(the diameter of one patient with Ross-Konno operation increased), but the annulus diameter increased with age. There was no need for further intervention.Conclusion:The Ross operation is safe for the treatment of aortic valve disease, it has good hemodynamic effect, and the autologous pulmonary artery has growth potential, especially suitable for children and young patients. Hand-sewn ePTFE with trileaflet vessels for reconstruction of right ventricular outflow tract performs well in anti-regurgitation function in the short term or may be used as a replacement material for the homograft/heterograft vessel, but longer follow-up and more cases are needed.

Objective:To assess the knowledge of Chinese nurses regarding disaster and emergency preparedness and its related factors.Methods:A total of 1 950 nurses were randomly selected from 152 hospitals of 30 provinces and municipalities in China. Two questionnaires were used to collect general data and associated information. The scale of nurse disaster emergency knowledge includes six dimensions: the function of emergency command system (ICS), the role, triage, communication, special care and isolation decontamination, report and access to important resources, biological agents. All of the data were analyzed with SPSS 20.0.Results:Totally 1 950 valid questionnaires were collected. The average score of Chinese nurses was (147.5 ± 33.8) (index value: 73.75%), which was at a middle level. And it was greater than that of the domestic norm. Among the six dimensions, knowledge of triage yielded the highest score (21.25 ± 5.55) (index value: 85.00%), and knowledge of biologics had the lowest score (10.21 ± 3.00) (index value: 68.07%). Education background, professional title, job position, experience, training and identity also were important associated factors ( t values were -4.107-12.376, P<0.01). Conclusion:Chinese nurses have a moderate level of knowledge of disaster and emergency preparedness. Health administrators should constantly enhance framework for disaster and emergency nursing core competencies, and enrich the content and methods of training. Further, simulation-based training and participation in large-scale disaster relief could improve nurses knowledge of disaster and emergency preparedness.
