Objective:To analyze the status quo, hotspots and fronts of emergency nursing training research at home and abroad in the past ten years, and to provide reference and ideas for the efficient development of emergency nursing training in China.Methods:CiteSpace 6.2.R2 software was used to visually analyze the Chinese and English literatures on emergency nursing training included in CNKI and Web of Science core databases from January 1, 2013 to June 1, 2023.Results:A total of 1 177 Chinese literatures and 1 163 English literatures were included. The number of foreign articles in this field increased year by year, while the number of domestic articles showed a downward trend since 2018. There were many stable core author groups and core institution groups in foreign countries, while there was less cooperation among domestic authors and institutions. The common research hotspots and frontiers at home and abroad focused on broadening the training audience of emergency nursing, innovating the training methods of emergency nursing, strengthening the evaluation of the effect of emergency nursing training, and paying attention to the training experience and needs of nurses. Foreign researches also focused on specialized nurses, interprofessional education and nurses′mental health, etc, and the research direction was diversified.Conclusions:The development stages of emergency nursing training researches at home and abroad are different, and the research hotspots are different. In the future, we should learn from foreign research, strengthen interdisciplinary cooperation, improve the depth and breadth of research, and strengthen the cooperation between authors, institutions and countries to promote the high-quality development of emergency nursing training research in China.

Apheresis platelets are extensively utilized in clinical practice due to high purity and minimal side effects. These platelets are primarily obtained from regular blood donors. However, there is no consensus on whether plateletpheresis leads to iron deficiency among blood donors. In recent years, increasing attention has been given to the impact of plateletpheresis on the iron nutritional status of these donors. Numerous studies have indicated a prevalence of iron deficiency among plateletpheresis donors. The process of plateletpheresis involves the loss of red blood cells, which can accumulate over time and disrupt iron metabolism, ultimately resulting in iron deficiency anemia. This condition not only affects the physical well-being of the donors but also leads to a decline in their willingness to donate blood. Blood collection and supply institutions should enhance their focus on the iron nutritional status of plateletpheresis donors and implement various measures, such as intensifying health education regarding the significance of iron supplementation, implementing programs for testing iron deficiency, considering the provision of iron supplements and extending blood donation intervals. It is crucial to prevent iron deficiency in plateletpheresis donors. These institutions should explore calculation models that can predict personalized blood donation intervals and iron supplementation strategies, and seek a balanced approach that is optimal for maintaining adequate collections while safeguarding donor health. The article comprehensively reviews literature at home and abroad on the etiology and hazards of iron deficiency in plateletpheresis donors, as well as detection methods and response measures. It serves as a foundation for developing scientific and reasonable care measures for blood donation, while also achieving personalized and scientific management and recruitment strategies for blood donors.

Objective:To investigate the status and the influencing factors of influenza vaccination during the COVID-19 pandemic among community-dwelling elderly in Shanghai.Methods:A questionnaire survey on influenza vaccination among community-dwelling elderly was conducted in Shanghai Taikang elderly community in November 2020. The information on demographic characteristics, reasons for refusal of vaccination, and measures for increasing vaccination rates were collected. Multiple logistic regression was used to analyze the correlation between influenza vaccination and sociodemographic and health-related characteristics.Results:Among 520 respondents, the vaccination rate was 30.58% (159/520). Compared with unvaccinated group, elderly in vaccinated group was older ( t=16.04, P=0.003)and more educated(χ2=8.16, P=0.043). The elderly with comorbid heart disease, chronic obstructive pulmonary disease, tumor, asthma, Parkinson′s disease were likely to have vaccination ( OR=1.45, 2.16, 1.23, 1.64, 5.83; all P<0.05).The reasons for the elderly not to be vaccinated were concerns of side effects (46.26%, 167/361), lack of doctors′ recommendations (24.10%, 87/361), and unnecessary for people with good health conditions (19.39%, 70/361). The independent factors of influenza vaccine awareness rate were healthcare providers′ recommendations ( OR=9.18, 95% CI:5.47-16.32), vaccination at home( OR=11.79, 95% CI:6.87-21.66),vaccination available in community( OR=8.08, 95% CI:8.08-15.45),the mandatory requirement ( OR=4.61,95% CI:4.61-10.11),free of charge( OR=7.48, 95% CI:4.08-15.12). Conclusion:Influenza vaccination coverage among the elderly in Shanghai is still low even during the COVID-19 pandemic. Policy interventions, awareness education and strengthening the primary healthcare resources may contribute to achieving a high influenza vaccine coverage rate in the community-dwelling elderly

ObjectiveTo analyze the epidemiological characteristics of senile dementia death in Jing’an District from 2016 to 2020， as well as the trends of mortality， standardized mortality， years of life lost （YLL） due to early death， years lived with disability （YLD）， and disability-adjusted life year （DALY）， and to provide scientific basis for the prevention and control of senile dementia. MethodsThe distribution of senile dementia in terms of gender， age， marital status and education level was investigated in the senile dementia death cases from 2016 to 2020 in Jing’an District. The YLL， YLD， DALY and their rates of the residents of Jing’an District from 2016 to 2020 were calculated by using Global Burden of Disease （GBD 2019） research method and results in combination with the corresponding population data. ResultsCompared to those without dementia， deaths with dementia were more likely to be female， more likely to be over 80 years old， less likely to be married， and more likely to have education level under middle school. Among the deaths with dementia， only 27.70% of the primary cause of death was dementia， and the other main causes were cerebrovascular disease， coronary heart disease and diabetes mellitus， which accounted for 25.54%， 17.81% and 7.28%， respectively. There was a significant gender difference in the burden of disease on senile dementia in Jing’an District. Mortality， standardized mortality， YLL， YLD and DALY rates of females were higher than those of males. The burden of disease on senile dementia increased with age. The change trend of mortality and YLL rate from 2016 to 2020 was not statistically significant， while the YLD rate and DALY rate showed an upward trend， which was statistically significant. ConclusionAs the life span of residents in Jing’an District increases and the population aging deepens， the burden of disease on senile dementia is still heavy. This requires extensive attention of the whole society， and active exploration of prevention and control strategies and measures for senile dementia， so as to improve the life quality of patients and reduce the burden of disease.

Background Diabetes mellitus is a major public health issue at present. Previous studies have shown that ambient air pollution is a risk factor for diabetes. Objective This study aims to explore the acute effects of ambient air pollution on diabetes related death in Shanghai Jing’an District. Methods Daily air pollution data, meteorological data, and diabetes related mortality data in 2013−2019 in Shanghai Jing’an District were collected. A generalized additive model (GAM) was established to conduct time-series analysis on the short-term effect of ambient air pollution on diabetes related mortality, and gender- and age-stratified analysis on susceptibility of various groups to ambient air pollution exposures. Results For every 10 μg·m⁻³ increase of the concentrations of PM_2.5, PM₁₀, SO₂, and NO₂, the diabetes related mortality increased by 2.47% (95%CI: 1.56%−3.38%), 2.02% (95%CI: 1.29%−2.75%), 5.75% (95%CI: 2.99%−8.58%), and 3.93% (95%CI: 2.49%−5.39%) at lag05 respectively (P<0.05). In the stratified analysis, exposures to increased concentrations of PM_2.5, PM₁₀, SO₂, and NO₂ raised the mortality risks from diabetes in male, female, and ≥65 years oldgroups (P<0.05). However, the differences in mortality risks from diabetes due to air pollution within gender and age groups were statistically insignificant. Conclusion In Shanghai Jing'an District, the elevated levels of ambient air pollutants, including PM_2.5, PM₁₀, SO₂, and NO₂, are significantly associated with the increase of diabetes related mortality, and there are lag effects and cumulative effects. The ≥65 years olds are more susceptible to the impact of air pollution on diabetes related deaths.

Objective: To explore the predictive value of ¹⁸F-fluorodeoxyglucose (FDG) PET conventional parameters and radiomics features for human epidermal growth factor receptor 2 (HER2) expression which was uncertain by immunohistochemistry (IHC) detection in invasive breast cancer. Methods: From April 2012 to December 2017, 76 patients (all were females, age: (50.8±10.9) years) with invasive breast cancer and with uncertain HER2 expression by IHC in Tianjin Medical University Cancer Institute and Hospital were enrolled retrospectively. The ¹⁸F-FDG PET/CT images before treatment were reviewed and the expression of HER2 were confirmed by fluorescence in situ hybridization (FISH). The tumor lesions were manually outlined, and the radiomics features from PET images were extracted. Wilcoxon test was used to determine whether there was difference in PET conventional metabolic parameters (maximum standardized uptake value (SUV_max), metabolic tumor volume (MTV) and total lesion glycolysis (TLG)) and radiomics features between HER2-negative and HER2-positive groups. The receiver operating characteristic (ROC) curve analysis was used to compare the predictive efficacy of PET radiomics features for HER2 expression. Results: There were 41 HER2-positive patients and 35 HER2-negative patients. No significant differences in PET conventional metabolic parameters between different HER2 expression groups were observed (U values: from -1.598 to 1.551, all P>0.05). A total of 38 PET radiomics features were extracted, and there were significant differences in gray mean, correlation, contrast, inertia, and inverse different moments between 2 groups(U values: from -2.413 to 2.527, all P<0.05). The area under the curve of the above 5 parameters for prediction of HER2 expression were 0.643, 0.638, 0.647, 0.644 and 0.643, respectively, and the contrast was the best parameter. Conclusions PET radiomics features can effectively identify HER2 expression in patients with invasive breast cancer to some extent, and the contrast may be the best. Conventional metabolic parameters have limited predictive value.

Objective To investigate the effect of curcumin(Cur)on proliferation and apoptosis of human esophageal carcinoma drug-resistant cells Eca-109/VCR in vitro and in vivo. Methods The inhibitory effect of Cur on Eca-109/VCR was detected by CCK-8 method. The apoptosis rate of Eca-109/VCR cells after treatment with Cur was determined by flow cytometry. Eca-109/VCR xenografts were established in nude mice and inhibitory effect of Cur on xenografts was observed. HE staining was used to observe the morphological changes. Apoptosis was detect-ed by TUNEL. ELISA was used to measure Caspase-3,Caspase-8 and Caspase-9 expression in nude mice serum. Results Cur significantly inhibited the proliferation of Eca-109/VCR in a time and concentration-dependent man-ner and it could induce apoptosis of Eca-109/VCR. Cur significantly inhibited the growth of xenografts and a large number of necrosis existed in Cur group. Cur induced apoptosis in xenografts and the expression of Caspase-3,Cas-pase-8 and Caspase-9 in serum increased with the increase of Cur concentrations. Conclusion Cur could inhibit the growth of esophageal carcinoma xenografts in vitro and in vivo and its role might be up-regulating the expression of Caspase-3,Caspase-8 and Caspase-9 and associated with the apoptosis induction of drug-resistant esophageal carcinoma cells.

Objective To analyze the clinical features and risk factors for mortality of patients with severe fever with thrombocytopenia syndrome (SFTS) in Zhoushan, the eastern coastal of China with high incidence of severe fever with thrambocytopenia syndrome bunyavirus infection, to provide reference for reducing the mortality rate of SFTS.Methods Clinical data of 107 cases of SFTS from Zhoushan Hospital during June 2011 to June 2016 were retrospectively analyzed.According to the prognosis, patients were divided into survival group and death group.The clinical features and the laboratory results were analyzed with a case-control method to analyze the prognostic factors.Normal distribution data were compared with the independent t test.Kolmogorov-Smirnov Z test were used in data with skewness distribution.Categorical data were analyze by chi-square test.The related risk factors were analyzed with the receiver-operating characteristic (ROC) curve and multivariate unconditioned logistics regression analysis.Results Seventeen cases among 107 STFs patients died, yielding the mortality rate of 15.9%.The proportion of patients suffering from two or more underlying diseases, with disorders of consciousness, activated partial thromboplastin time (APTT), the level of creatine kinase (CK), lactate dehydrogenase (LDH) as well as sepsis-related or sequential organ failure assessment (SOFA) score in death group were all significantly higher than those in the survival group (all P<0.05).The Ca2+ level and fibrinogen level in death group were significantly lower than those in the survival group (both P<0.05).Indexes mentioned above were analyzed by ROC curve, and the calculated cut-off value was set as the optimal diagnostic thresholds.These data were then included into the multivariate logistic regression analysis.It turned out that Ca2+<1.625 mmol/L, APTT >73.45 s, SOFA scores >9 were the independent risk factors for mortality of SFTS (OR=6.947, 8.459 and 11.770, respectively, all P<0.05).Conclusion Ca2+, APTT and SOFA score are the independent risk factors for prognosis of SFTS, which provide reference for prognostic evaluation of SFTS.
