It is characterized by multiple and severe symptoms and rapid progression of the disease，which seriously threatens the life safety of patients. In this paper，the relevant studies on symptom cluster of patients with ACS were systematically searched at home and abroad，and the composition of symptom cluster，symptom assessment tools，symptom cluster establishment methods，influencing factors and intervention methods were reviewed，in order to provide references for nurses to manage ACS symptom cluster.

Objective To conduct a scoping review of the research on the Persuasive Systems Design Model in self-management information systems for patients with chronic diseases，so as to clarify the related concepts of the persuasive systems，identify the elements of the persuasive systems，and provide guidance for future research in this field. Methods Based on the methodological framework of the Australia Joanna Briggs Institute Scoping Review Guide，CNKI，Wanfang，VIP，Sinomed，PubMed，Web of Science，PsycINFO，Cochrane Library，CINAHL and Embase databases were retrieved from the date of establishment of the databases to September 2022，and the included studies were analyzed. Results A total of 22 pieces of literature published from 2010 to 2022 in English were included. The included 22 studies were all themed on the construction of self-management information systems for patients with chronic diseases based on the Persuasive Systems Design Model. The content included physical activities，dietary habits，medication management，weight management and symptoms monitoring. Conclusion The self-management information systems for patients with chronic diseases based on the Persuasive Systems Design Model can influence the attitude and behavior of patients，motivate patients to engage in self-management and trigger health behavior change，which play a significant role in guiding patients with chronic diseases and show a positive application effect.

Objective To explore the application and effect of Vivifrail multi-component exercise intervention program in patients with major neurocognitive disorders. Methods In this quasi-experimental study，52 patients with major neurocognitive disorders who were hospitalized in a municipal psychiatric hospital from June 2021 to June 2022 were selected as research subjects and divided into Ward A as the intervention group（26 cases） and Ward B as the control group（26 cases）. The control group was treated with routine nursing，and the intervention group was treated with 12-week Vivifrail multi-component exercise on the basis of routine nursing. Short Physical Performance Battery（SPPB），Timed "Up and Go" Test（TUGT），6 Minutes Walking Test（6MWT） and Chair Sit and Reach（CSR） were used to evaluate physical function in both groups before and after intervention. Results After 12 weeks of intervention，the total score of SPPB（t=-4.312，P<0.001） and its 3 test dimensions-balance test（t=-3.029，P=0.004），4 m walking speed test（t=-3.972，P<0.001），chair standing test（t=-2.912，P=0.005），and CSR test results （t=-3.446，P=0.001） were significantly different between the 2 groups. The results of repeated measures analysis of variance showed that all the indexes in the 2 groups had interaction effects（P<0.001）. Except for the 4 m walking test of SPPB，the time effects of other indexes were statistically significant（P<0.05），and the variables with statistical significance of intergroup effect included balance test of SPPB and CSR test（P<0.05）. Conclusion Vivifrail multicomponent exercise can significantly improve the balance function，walking speed，muscle strength and flexibility of patients with major neurocognitive disorders in medical institutions，but the improvement of body flexibility and heart and lung function was not obvious.

Objective To study the application value of the doctor-nurse-patient shared decision-making assistance program in the prevention of stroke in patients with atrial fibrillation. Methods Through literature review and expert discussion,treatment decision aid tools were constructed. The convenience sampling was adopted,and 62 atrial fibrillation patients who were willing to participate in treatment decision-making in a tertiary hospital in Zhejiang Province from April to July 2021 were selected as the research subjects. The patients were divided into a test group and a control group,with 31 patients in each group. The test group adopts the doctor-nurse-patient joint shared decision-making assistance program,and the control group adopts the conventional plan. The actual participation in treatment decision-making of the 2 groups of patients,the satisfaction of patients with participating in treatment decision-making,the conflicts of patients’ decision-making,and the INR compliance rate of the 2 groups of patients were analyzed. Results There were statistically significant differences in the degree of patients’ actual participation in treatment decision-making between 2 groups（P<0.001）.The test group was（42.26±6.38） points,and the control group was（26.48±7.31） points. There were statistically significant differences in patients’ satisfaction with participating in treatment decision-making between groups（P=0.04）. The test group was（74.68±11.68） points,and the control group was（49.68±15.26） points. There were statistical differences in the decision-making conflicts of patients between groups（P<0.001）. The test group was（24.81±6.72） points,and the control group was（45.39±8.47） points. There were statistically significant differences in the INR compliance rate of patients between 2 groups（P<0.001）. The INR compliance rate of the test group was 54.17%,and the INR compliance rate of the control group was 14.29%. Conclusion The treatment decision-making assistance for patients with atrial fibrillation in the prevention of stroke have significant clinical significance on patients’ participation in treatment decision-making,treatment decision-making satisfaction,decision-making conflict and INR compliance rate.

Objective To retrieve,evaluate and summarize the best evidence for the evaluation and prevention of pregnancy associated venous thromboembolism（PA-VTE）,so as to provide references for clinical management. Methods We searched the literature from the clinical decision-making system UpToDate,BMJ Best Practice,Embase,Springer Link and other websites or databases to collect relevant guidelines,systematic reviews,best practice information sheets,evidence summaries and expert consensuses. The search period was from January 2015 to May 2021,and 2 researchers conducted independent literature evaluation,and 4 researchers conducted evidence extraction,translation,and integration. Results A total of 11 articles were included,including 4 guidelines,1 clinical decision,3 expert consensuses,and 3 systematic reviews. 20 pieces of evidence were summarized from 7 aspects of PA-VTE assessment of risk factors,assessment timing,assessment tools,basic prevention,drug prevention,and health education. Conclusion This study summarizes the best evidence for the evaluation and prevention of PA-VTE. It is recommended to develop maternal VTE risk assessment tools that meet the national conditions,screen VTE risk factors and manage them in layers,and strengthen maternal VTE health education to achieve the goal of reducing the incidence of PA-VTE.

Finally,42 pieces of best evidence were formed from 7 aspects,namely long-term oxygen therapy,nocturnal oxygen therapy,ambulatory oxygen therapy,short burst oxygen therapy,palliative oxygen therapy,safety of oxygen therapy and follow-up of oxygen therapy. Conclusion This study summarized the best evidence of home oxygen therapy for COPD patients,and provided evidence-based bases for medical staff to formulate reasonable follow-up plans,standardize home oxygen therapy practice,and ensure the safety of home oxygen therapy.

Objective To systematically evaluate the efficacy and safety of plastic wrap for prevention of hypothermia in newborn infants.Methods We searched databases including Cochrane Library,PubMed,Scopus,CINAHL,CBM,Wanfang,VIP,and CNKI. We included all randomized controlled trials which investigated the efficacy and safety of plastic wrap on prevention of hypothermia in newborn infants. Studies were selected according to inclusion and exclusion criteria,data were extracted and study quality was appraised. RevMan 5.2 software was used to analyze the data.Results Sixteen randomized controlled trials which included 2 836 participants were included. The results of meta-analysis showed that hypothermia on admission to the NICU [RR=0.71,95%CI（0.64,0.79）,P<0.01],core body temperature on admission to the NICU[MD=0.60,95%CI（0.47,0.72）,P<0.01],and hyperthermia on admission to the NICU[RR=4.09,95%CI（2.12,7.88）,P<0.01] in the wrapped group were significantly different with those received routine care. There was no significant difference in IVH（grades Ⅲ or Ⅳ）[RR=0.92,95%CI（0.65,1.32）,P=0.66] and death during hospital stay[RR=0.75,95%CI（0.53,1.08）,P=0.12] between the wrapped group and control group.Conclusion Usage of plastic wrap compared with routine care can lead to less hypothermia on admission to NICUs with higher temperature among premature infants（<28 weeks,or ≥28 weeks premature infants）. Caution must be taken to avoid iatrogenic hyperthermia. Plastic wrap cannot decrease the rate of IVH（grades Ⅲ or Ⅳ） and mortality during hospital stay in premature infants.
