Objective:To develop the training syllabus of palliative care for general practitioners.Methods:Twenty-nine experts in fields of general practice and hospice care from different teaching hospitals and community health service centers were invited to participate in two rounds of Delphi consultation from April 2022 and August 2022. Based on results of Delphi consultation a preliminary training syllabus was established through data analysis, synthesis and process.Results:Of the 29 experts, 11 (37.9%) were male with age of (52.9±8.9) years and working experience of (17.0±7.2) years. The expert activity coefficient of the two rounds of consultation was 100.0% (29/29) and 96.6% (28/29), authority coefficient was 0.815 and 0.870, and opinion coordination coefficient was 0.359 and 0.515, respectively ( P<0.05). The training syllabus comprised of 4 first-grade indicators, 19 second-grade indicators and 58 third-grade indicators. The weight coefficients of the 4 first-grade indicators, namely objective of training, theory courses and theoretical knowledge, clinical base rotation contents and requirements, community base rotation content and requirements, were 0.251, 0.251, 0.250 and 0.248, respectively. Conclusions:A preliminary training syllabus of palliative care for general practitioner has been developed in this study, which provide a basis for standardized training of community palliative care.

Objective:To analyze the selection of outcome indicators for randomized controlled trials (RCT) on exercise rehabilitation in patients with atrial fibrillation (AF), promote the construction of the core outcome set and provide reference for the research design of subsequent RCT.Methods:The RCT literature related to exercise rehabilitation of patients with atrial fibrillation was systematically searched from CNKI, Wanfang, VIP, PubMed, Web of Science, Embase and Cochrane Library databases, and the search period was from establishment of the databases until July 31, 2023. After literature screening, Cochrane Risk of Bias Assessment Tool was used for quality evaluation, information extraction, classification of outcome indicators, frequency of use statistics, analysis and extraction of current shortcomings in the selection of outcome indicators, and corresponding suggestions were proposed.Results:A total of 32 articles were included, and 19 RCT were evaluated twice for outcome measures. The number of outcome measures ranged from 2 to 17, with 10 RCT setting outcome measures according to primary and secondary criteria and 6 RCT setting safety outcome measures. A total of 96 outcome indicators were extracted in this study, total 266 frequency, which could be divided into 4 categories, such as safety evaluation (18 times), clinical response (75 times), patient-reported outcomes (68 times) and laboratory and other examination (105 times) .Conclusions:Existing RCT outcome indicators of exercise rehabilitation in patients with atrial fibrillation emphasize the changes in subjective feelings and objective indicators of individuals, covering four aspects such as the physical condition, exercise ability, quality of life and psychological status of individuals. However, there is a lack of uniform standards and the safety evaluation indicators are fewer. The categories of exercise rehabilitation indicators for atrial fibrillation patients extracted in this paper can provide a reference for the design of future RCT studies and promote the generation of higher quality evidence-based medical evidence.

Objective:To construct an evaluation index system for community hospice comfort care.Methods:This was a cross-sectional study. Two rounds of expert consultations were conducted using modified Delphi method from June to September 2023, 14 experts in the field of palliative care nursing were invited to participate in the consultations. Based on the consultation results, an evaluation index system for comfort care of community hospice was preliminarily developed.Results:All consultation experts were females, with an average age of (48±8) years; 9 held senior professonal titles, and 12 had more than 5 years of palliative care-related working experiencs. The positive coefficient of correspondence in two rounds of consultations was 100%, and the degree of authority was 0.841 and 0.834, respectively. The expert coordination coefficients for the importance of secondary indicators were 0.281 (χ 2=182.65) and 0.284 (χ 2=132.98), and the expert coordination coefficients for the operability of secondary indicators were 0.231 (χ 2=150.12) and 0.252 (χ 2=118.01), respectively. The constructed evaluation index system of hospice comfort care consisted of 5 primary indexes and 32 secondary indexes. The five primary indexes were environmental comfort, physiological comfort, psychological comfort, spiritual comfort and social comfort with a weight coefficient of 0.202 3, 0.205 3, 0.205 3, 0.199 4 and 0.187 7, respectively. Conclusion:An evaluation index system for comfort care in community hospice has been preliminarily developed in this study, after validation it would provide a reference for assessing the comfort needs of patients with palliative care.

Objective:To investigate the effect of nuclear factor-erythroid 2-related factor 2 (Nrf2) gene on the proliferation and apoptosis of colorectal adenocarcinoma cells in vitro, and the role of Nrf2 gene in regulation of epithelial-mesenchymal transition (EMT) pathway.Methods:Three Nrf2 small interfering RNA (siRNA) sequences were designed and synthesized, namely siRNA-223, siRNA-538 and siRNA-756, and the unrelated sequences were designed and synthesized. The plasmids carrying various siRNA sequences of Nrf2 were constructed, and the plasmids carrying siRNA sequences and the plasmids carrying unrelated sequences were transfected into human colorectal adenocarcinoma Caco-2 cells, namely interference group and empty vector group, respectively. Additionally, Caco-2 cells without any treatment were used as the control group. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blotting (WB) methods were used to detect the relative expression of Nrf2 gene in transcription and translation levels in each group of cells, in order to verify the interference effect of Nrf2; the siRNA with the best interference effect was selected for subsequent experiments. CCK-8 method was used to detect the proliferation ability of each group of cells (expressed as absorbance value); RT-qPCR was used to detect the relative expression of EMT pathway-related factors [vimentin (Vim), N-cadherin (N-cad) and E-cadherin (E-cad)] in transcription level in each group of cells; WB method was used to detect the expression of pro-apoptotic protein Bax in each group of cells.Results:The results of RT-qPCR and WB methods showed that compared with the control group and the empty group, the relative expression of Nrf2 gene in transcription and translation levels in Caco-2 cells of the siRNA-756 interference group were the lowest, and the differences were statistically significant (all P < 0.05). The CCK-8 results showed that the absorbance values of Caco-2 cells in the control group, empty group and siRNA-756 interference group after 48 hours of culture were (100±5)%, (94±4)% and (82±5)%, respectively; compared with the control group and the empty group, the siRNA-756 interference group had lower absorbance value, and the differences were statistically significant (all P < 0.05). The results of RT-qPCR method showed that the relative expression of Vim and N-cad in transcription level in the siRNA-756 interference group were higher than those in the control group and the empty vector group, and the differences were statistically significant (all P < 0.05); the relative expression of E-cad in transcription level was lower than those in the control group and the empty vector group, and the differences were statistically significant (both P < 0.05). The results of WB method showed that the relative expression of Bax protein in the siRNA-756 interference group was higher than that in the control group, and the difference was statistically significant ( P < 0.05). Conclusions:Interference with Nrf2 expression in vitro can weaken the proliferation and anti-apoptotic abilities of human colorectal adenocarcinoma Caco-2 cells. The mechanism may be that Nrf2 regulates the expression of Vim, N-cad and E-Cad in the EMT pathway to enhance the EMT ability of tumor cells.

Objective:To investigate the work stress and its influencing factors among hospice care physicians and nurses in medical institutions in Shanghai.Methods:It was a cross-sectional study. The study was carried out between December 2021 and January 2022. By use of multistage random sampling, 256 hospice care physicians and nurses were selected from community healthcare centers, secondary and tertiary hospitals in Shanghai to attend a WeChat-based survey using a self-designed questionnaire. The chi-square test was used to compare the differences in prevalence of work stress and stressors among all subjects with different characteristics. Binary logistic regression analysis was used to explore the major determinants associated with work stress. And the sources of work stress and the expepectd decompression countermeasures were investigated.Results:A total of 256 valid questionnaires were collected with a recovery rate of 100.0%. The median of work stress score was 7.5 (6.0, 9.0). Logistic regression analysis showed that those aged>40 years old and working for ≥5 years in hospice care service had higher level of work stress ( OR=3.78, 2.04; P=0.007, 0.039), and those with monthly income>10 000 RMB Yuan had lower level of work stress ( OR=0.34, P=0.005). The top three stressors were the death of patients (88.3%, 226/256), low income (78.1%, 200/256), difficulty in promotion (67.2%, 172/256). The top three way that doctors and nurses desired to reduce work stress were to increase income (88.3%, 226/256) and optimize performance appraisal target (78.1%, 200/256) and promotion mechanism (66.0%, 169/256). Conclusions:In general, the work stress among hospice care physicians and nurses is at a high level in Shanghai and the stressors are widely distributed. Age, monthly salary and years of working in hospice care unit are independent factors of work stress. Improving salary, optimizing performance appraisal target and promotion mechanism are the most desired strategies to reduce work stress among hospice care physicians and nurses.

Objective:To survey the status quo of hospice care service in community health service centers in Shanghai.Methods:A questionnaire survey was conducted to investigate the situation of hospice care services from January 2021 to December 2021 in 16 community health service centers selected by stratified sampling from 16 districts in Shanghai.Results:Among 16 community health service centers, 13 provided inpatient hospice care services, 16 provide home hospice care and 14 provided outpatient hospice care services; and totally 1 935 (77.93%), 158 (6.36%) and 390 (15.71%) patients received palliative care, respectively. In centers providing inpatient hospice care service, the average bed number was 12 (10, 20); the annual number of patients was 58 (29, 137); the average length of hospital stay was (29.55±11.18) days; and the bed occupancy rate was (55.51±30.02)%, which in urban districts was significantly higher than that in rural districts ((74.76±19.33)% vs.(39.00±28.32)%; t=2.61, P=0.024). The number of patients receiving home hospice care in each center was 10 (3, 19) and the average duration of home service was (66.97±29.41) days. The proportion of physician fee of inpatient hospice care and that of home hospice care were (8.61±5.27)% and (6.25±3.11)%, respectively. While the proportion of medication expenses of inpatient hospice care and that of home hospice care were (35.60±16.13)% and(49.58±9.16)%, respectively. The outpatient hospice service were opened 2.0 (1.0, 4.0) days a week in 14 centers and 95 (58, 199) patients received services. Inpatient services were mainly provided for the patients with non-malignant chronic diseases (53.23%, 1 030/1 935), while home hospice care (89.87%, 142/158) and outpatient hospice care (83.85%, 327/390) mainly provided service for malignant patients. Conclusion:There is still room for improvement about the hospice care services delivered by community health service centers in Shanghai:discrepancy of utilization of hospice care services between urban districts and rural districts, low utilization of home and outpatient hospice care services, unreasonable cost composition in inpatient and home hospice care services.

Objective:To develop the Pregnancy Weight Gain Control Intention Scale and test its reliability and validity.Methods:This is a cross-sectional study. The item pool of the scale was constructed based on the theory of planned behavior, literature review and semi-structured interview, and the draft of the scale was formed through expert correspondence and pre-investigation. From February to April 2022, a total of 300 pregnant women from 2 ClassⅢ Grade A hospitals in Zhenjiang were selected as research objects by convenience sampling method, and the scale was further revised through item analysis and exploratory factor analysis. From May to July 2022, a formal investigation was conducted among 350 pregnant women from 2 Class Ⅲ Grade A hospitals in Zhenjiang, and confirmatory factor analysis and reliability test were used to evaluate the reliability and validity. Two weeks after the completion of the survey, 30 pregnant women were selected for retest reliability test.Results:In the first stage of the survey, a total of 300 questionnaires were distributed, and 282 valid questionnaires were effectively collected, with an effective recovery rate of 94.00% (282/300). A total of 350 questionnaires were distributed in the second phase of the survey, and 324 valid questionnaires were effectively collected, with an effective recovery rate of 92.57% (324/350). The formal scale includes 3 dimensions and 20 items, namely behavior attitude, subjective norm and perceived behavior control. Three common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 80.198%. The results of confirmatory factor analysis showed that the scale structure model fit was well. The scale-level content validity index was 0.980, the item-level content validity index was 0.830-1.000, the Cronbach's α coefficient of the scale was 0.917, the split-half reliability coefficient was 0.709, and the retest reliability coefficient was 0.860.Conclusions:The Pregnancy Weight Gain Control Intention Scale has good reliability and validity, and can be used as an evaluation tool to evaluate the weight gain control intention of pregnant women.
