Objective To develop the Children's Screen Interaction Quality Questionnaire(CSIQ)suit-able for measuring Chinese children aged 0 to 4 years,and to test its reliability and validity.Methods The purposive sampling method was used,and the guardians of 30 normal children aged 0 to 4 years undergoing physical examinations in the Department of Child Health Care of Guiyang Maternal and Child Health Care Hospital from February to April 2023 were selected as the interview objects.25 initial items were constructed through literature review,semi-structured interviews,and the Delphi expert consultation method.With the convenience sampling method,2 242 guardians of children aged 0 to 4 years old in the small and middle classes of 9 kindergartens in Guiyang City,Zunyi City,and Renhuai City were surveyed for item analysis,exploratory factor analysis,confirmatory factor analysis,and reliability and validity analysis.Results Exploratory factor a-nalysis extracted three factors,namely screen content interaction,reality interaction,and media interaction,with a total of 12 items.The cumulative variance explained rate of the 3-factor model was 69.829％.Confirma-tory factor analysis supported the three-factor model of CSIQ:x2/df=4.424,root mean square error of ap-proximation(RMSEA)=0.066,normed fit index(NFI)=0.955,comparative fit index(CFI)=0.965,incre-mental fit index(IFI)=0.965,Tucker-Lewis index(TLI)=0.955,goodness-of-fit index(GFI)=0.955,and the CSIQ had good convergent validity and discriminant validity.Conclusion The CSIQ has good reliability and validity.

Objective:To investigate the current status and correlation between perceived stress and coping strategies among nurses in the Cardiac Intensive Care Unit (CICU) .Methods:A purposive sampling method was used to select 348 CICU nurses from ten tertiary hospitals in Beijing between March and October 2023. Data were collected using a general information questionnaire, the Chinese version of the Perceived Stress Scale (PSS), and the Simplified Coping Style Questionnaire (SCSQ) .Results:The score of the Chinese PSS among 348 nurses was (28.86±5.06). In the SCSQ, the score for positive coping was (22.71±7.57), while the score for negative coping was (8.57±4.82). Correlation analysis indicated that perceived stress was negatively correlated with positive coping strategies ( P<0.01) and positively correlated with negative coping strategies ( P<0.01). Multiple linear regression analysis showed that years of experience in the CICU, employment status, family support for work, and coping strategies were influencing factors of perceived stress ( P<0.05), explaining 50.2% of the total variance. Conclusions:CICU nurses generally experience high levels of perceived stress, and those who tend to adopt negative coping strategies report even higher stress levels. Nursing administrators should develop targeted interventions based on nurse characteristics to promote effective coping strategies and alleviate perceived stress.

Objective To investigate and analyze factors affecting depressive disorders in elderly stroke patients after rehabilitation treatment.Methods A total of 1 100 elderly stroke patients receiving rehabilitation treatment in the three hospitals(Beijing Electric Power Hospital of State Grid Corporation,Beijing Fengtai Hospital of Integrative Medicine and Beijing Daxing Hospital of Integrative Medicine)were selected as the study subjects.General data were collected,and patients were surveyed using the daily life ability scale(BI),family care scale and social support scale(SSRS),according to the Hamilton Depression Scale(HAMD)to determine whether patients developed depressive disorders.Multivariate Logistic regression analysis were used to analyze influencing factors of depressive disorders in elderly stroke patients after rehabilitation treatment.Results A total of 1 100 survey questionnaires were issued and 1 073 were retrieved,with an effective rate of 97.5%,and among them,386 cases(36.0%)were diagnosed with depressive disorder,and 687 cases(64.0%)without depressive disorder.There were significant differences in the incidence of depression between patients with different ages,complications,per capita family income,BI score,family caring degree and SSRS score(P＜0.05).Multivariate Logistic regression analysis showed that advanced age(OR=1.337,95%CI:1.014-1.763),complication(OR=3.214,95%CI:1.365-7.569),lower per capita monthly family income(OR=2.263,95%CI:1.137-4.503),lower BI score(OR=1.872,95%CI:1.158-3.026),average family caring degree(OR=2.639,95%CI:1.200-5.802)and lower SSRS score(OR=1.557,95%CI:1.044-2.322)were risk factors for depression in elderly stroke patients after rehabilitation treatment(P＜0.05).Conclusion More attention should be given to elderly stroke patients to improve family care and social support,thus reducing the risk of depressive disorders after rehabilitation.

Disease control priority(DCP)is an important public health intervention strategy.Diseases that should be prioritized for prevention and control are first screened with a series of criteria,including the severity of the disease burden,the effectiveness of disease control technologies,the prevention and control capacity of the existing health system,etc.Then,the prevention and control technologies for these diseases undergo qualitative evaluation(eg,face-to-face interviews,expert consultation,workshops,etc)and quantitative evaluation(eg,cost-benefit analysis,multi-criteria decision analysis,etc).Finally,the public health initiatives that should be prioritized are identified.From the conception of the idea,to the formal proposition of the concept,to guidance for practice,DCP has gone through more than 70 years of development.Through DCP,significant contributions has been made to improving the efficiency of health care service systems and promoting the health of populations in developing countries.Herein,we systematically reviewed the background,development history,realization method,and practical applications of DCP,focusing on exploring the application potential of DCP in health governance and providing technical support and decision-making reference for the comprehensive promotion of the Healthy China Initiative.

Objective:To understand the molecular transmission characteristics of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome(AIDS) patients in the mountainous area of southwest Zhejiang Province(Lishui city).Methods:A total of 147 blood samples were collected from newly-diagnosed HIV-1 infected who received no antiviral therapy, and pol gene was amplified, followed by sequencing. MEGA6.0 software was used to construct phylogenetic tree and determine gene subtypes. HIVDB online was used to analyze drug resistance mutation, then the pairwise genetic distance(GD) was calculated and the opitimal threshold of GD was selected, finally the molecular transmission network was constructed by Cytoscape3.7.0 software. Chi-square or Fisher′s exact probability method was used for statistical analysis. Results:A total of 134 sequences were obtained successfully, and nine subtypes were detected. The dominant subtypes were CRF08_BC (34.33%, 46/134), CRF01_AE (29.85%, 40/134) and CRF07_BC (23.88%, 32/134). It also found that age, registered residence, education level and transmission route had significant differences in distribution of subtypes ( P<0.05). Nineteen drug resistance individuals were found, and the total drug resistance rate was 14.18% (19/134). The HIV-1 molecular transmission network was plotted based on 1.2% GD threshold. A total of 15 transmission clusters (cluster size ranging from 2 to 29) were found. The network access rate was 49.25% (66/134), mainly including male (75.76%, 50/66), heterosexual (81.82%, 54/66) and patientsrinfected with CRF08_ BC (50.00%, 33/66). A transmission cluster including two cases of female sex workers and seven cases of drug resistance was identified, in which the average age of the patients was 57.21 years old and the average degree value was 22.7, and the cases were mainly infected through heterosexual contact (96.55%, 28/29). The highest homology of the sequences in the cluster was in Yunnan. Conclusions:The HIV-1 subtypes were diverse in the mountainous area of southwest Zhejiang Province(Lishui city). Drug resistant transmission had reached a moderate epidemic level. There were molecular transmission clusters with the aggregation characteristics of elderly clients in specific regions. It was urgent to formulate and implement precise intervention strategies to curb the spread of HIV.

Objective To evaluate the safety and feasibility of early feeding in children after orthopaedic surgery.Methods Totally 638 children with general anesthesia after orthopaedic surgery in a tertiary hospital in Beijing were recruited and divided into two groups.Children in the experimental group (n=315) started water drinking and feeding if they passed the postoperative assessment on consciousness and digestive function,while children in the control group (n=323) adhered to the conventional protocol of 6h fasting postoperatively.Results The average initial time of water drinking,liquid food feeding and general diet in the experimental group were 0.63 h,1.03 h and 3.07 h,while they were 6.42 h,6.88 h and 8.79 h in the control group,and the differences were statistically significant (P＜0.001).There were no significant differences in the incidence,severity and frequency of postoperative nausea and vomiting between two groups in 6h and 24h after returning to wards(P＞0.05).At 6h after returning to wards,the incidences of moderate-to-severe thirst and hunger in the experimental group were significantly lower than those in the control group(P＜0.001),and pain scored over 3 marks was lower than the control group(P=0.002).Conclusion Children after orthopaedic surgery with general anesthesia are likely to drink water 1 h after returning to wards and then take general diet 2h later while comprehensive prevention measures being adopted.Early teeding would not aggravate postoperative nausea and voniting and can alleviate the extent of postoperative thirst,hunger and pain.

Objective To explore the effect of 5M1E quality analysis tool-based hand hygiene(HH) comprehensive intervention measures on pediatric healthcare-associated infection(HAI).Methods HH status of 29 health care workers(HCWs) in the pediatric department of a hospital was monitored, April-June 2015 was baseline survey stage, 5M1E quality analysis tool was adopted to analyze various factors affecting the compliance rate of pediatric HH, intervention measures began to be taken in June 2015, and compared with HH in July 2015-March 2016.The occurrence of HAI between July 2014-March 2015 and July 2015-March 2016 was compared.Results HH compliance rate of HCWs increased from 30.86% in April-June 2015 to 81.94% in January-March 2016;HH correct rate increased from 68.14% to 93.75%;HH compliance rate and correct rate of HCWs gradually increased(X2=2 608.626, 630.798,respectively, both P<0.001).Qualified rate of detection of HCWs' HH sampling increased from 20.69% in April-June 2015 to 89.66% in January-March 2016(X2=31.957,P<0.001).Incidence of HAI decreased from 7.74% in July 2014-March 2015 to 3.62% in July 2015-March 2016(X2=46.717,P<0.001).Conclusion Application of 5M1E quality analysis tool in the investigation, analysis, and comprehensive intervention in HCWs' HH in pediatric department has greatly enhanced HCWs' HH compliance rate, and reduced the incidence of HAI in pediatric patients.

Objective To develop an effective nursing intervention for PICC local infection in pediatric patients with tumors based on the best evidence obtained by methods of evidence-based nursing. Methods Questions were raised regarding the diagnosis and grading of PICC local infection in pediatric patients with tumors and the implementation of corresponding clinical care. Relevant literature evidence was reviewed using both electronic and manual library search. Results Relevant literature evidence about the diagnosis and grading of PICC local infection in pediatric patients with tumors and corresponding clinical care was identified, followed by a critical appraisal process. The criteria, used in our department, for diagnosis and grading of PICC local infection in pediatric patients with tumors and corresponding clinical care measures were formulated according to relevant evidence, current clinical status of our department and willingness of patients. Thereafter, corresponding clinical care measures were applied to 32 tumor pediatric patients with PICC local infection in our department according to the grading of infection. Good therapeutic effect was achieved and PICC local infection did not lead to chemotherapy delay or unplanned extubation in any pediatric patient. Conclusions The approach of evidence-based nursing can be used to effectively resolve common nursing problems in clinical practice, promote the ability of nursing staff to obtain and apply the best evidence and promote the scientificity and validity of nursing practice.

Objective To investigate the immunological reaction mechanism of medicated serum in Zibai Gelatin for SiHa cells of the cervical cancer infected by high risk human papilloma virus (HPV). Methods Through immunohistochemical comparison and the cell culture, and after medicated serum was administrated to SiHa cells of cervical cancer for 24 h, 48 h, and 72 h, optical densities of IL-6, IL-10, CD83 and TNF-αin the same time but different concentrations and different times but the same concentration were observed. Relationships of dose-effect and time-effect between expressions of IL-6, IL-10, CD83 and TNF-α and medicine action were analyzed by calculating average optical density. Results With the increase of medicine concentration and administration time of Zibai Gelatin, the expressions of IL-6 and TNF-αgradually decreased, while the expressions of CD83 and IL-10 gradually increased (P<0.05). Conclusion Zibai Gelatin with medicated serum can inhibit local inflammatory reaction by improving local immunologic function of cervix, which is beneficial to reduce cervix high-risk HPV.
