Objective:To explore the influence of humanistic management atmosphere on nurses′ intention to stay in hospital, so as to provide reference for stabilizing nursing team.Methods:The convenience sampling method was used to investigate 1 044 clinical nurses in 5 tertiary hospitals in Shandong province by using the general information questionnaire, nurses′ perception of humanistic management questionnaire and nurses′ intention to stay questionnaire in May 2019.Four dimensions of demographic factors and nurses′ perception of hospital humanistic management were used as independent variables, and the total score of nurses′ intention to stay was used as dependent variable for stepwise regression analysis.Results:The total scores of humanistic management perception and intention to stay were 166.70±29.42 and 23.30±4.29 respectively. There was a positive correlation between humanistic management perception and intention to stay( P<0.05). The three dimensions of human management perception, emotional management perception and cultural management perception, as well as the professional title, working years and employment form could explain 27.5% of variation. Conclusions:The nurses′ intention to stay is in the middle and upper level, which is related to the hospital′s humanistic management. The perception of humanistic management of nurses has a positive predictive effect on the intention to stay, especially in talent management, emotional management and cultural management. Hospital managers should improve the humanistic management mode, enhance nurses′ perception of humanistic management in order to stabilize the nursing team and improve nurses′ intention to stay.

Objective:To observe the therapeutic effect of microwave ablation combined with anhydrous ethanol for cystic thyroid nodules.Methods:From Jan. 2019 to Dec. 2019, 56 patients with thyroid cystic nodules (≥2cm) underwent ultrasound guided thyroid cystic nodule ablation in Department of Thyroid and Breast Surgery, Nanjing Hospital of Traditional Chinese Medicine. According to different ablation methods, the patients were divided into microwave ablation combined with anhydrous ethanol group and microwave ablation group. There were 36 cases in microwave ablation combined with anhydrous ethanol group and 20 cases in microwave ablation group. The volume reduction rate of thyroid nodules, the incidence of postoperative complications and the changes of thyroid function were compared between the two groups after treatment. Statistical analysis were performed using SPSS, version 21.0, the mean±SD deviation ( ± s) was used to describe the statistics, t-test was performed, and the adoption rate of counting data (%) was expressed by χ 2 test. The difference was statistically significant with P<0.05. Results:The nodule volume reduction rates of the microwave ablation combined with anhydrous ethanol group and microwave ablation group were (49.86±6.78) % vs (22.84±1.88) %, (67.57±5.84) % vs (47.25±7.09) % and (75.70±4.51) % vs (71.14±4.65) % at 3 months, 6 months and 12 months after operation, respectively. There was significant difference between the two groups ( P<0.001) . The incidence of postoperative complications in the two groups was 38.89% and 45.00% respectively, and there was no significant difference between the two groups ( P>0.05) , and all complications were cured within 2 months. There was no significant difference in thyroid function (T3, T4, FT3, FT4, TSH) between the two groups before and 12 months after operation ( P>0.05) . Conclusions:Microwave ablation combined with anhydrous ethanol is more effective in treatment of cystic thyroid nodules (≥2cm) than microwave ablation alone. It can significantly improve patients’symptoms and nodule volume reduction, and does not affect thyroid function. It can be used as a recommended option for treatment of cysticthyroid nodules.

【Objective】 To analyze the relevant studies on blood donor cohort and explore the current research status, research hotspots and development trends of blood donor cohort studies abroad. 【Methods】 Based on the Web of Science Core Collection, the literature related to blood donor cohort was searched. After screening and data processing, bibliometric analysis was carried out from the volume of literature trends, disciplines, authors, institutional distribution and other aspects of the included literature. At the same time, CiteSpace 5.6R5 software was used to carry out visual analysis of countries/regions, literature co-citation, keyword co-occurrence, keyword clustering and keyword emergence. Results A total of 672 papers (654 research papers, 18 review papers) were included. The total number of papers published in the field of blood donor cohort study showed a steady upward trend since 1991, the fastest growth was between 2019 and 2020. The top three cited authors were Kaaks R (1 301 citations), Rinaldi S (1 186 citations) and Riboli E (1 130 citations); the top three institutions were RLUK library in the UK, the University of California and the University of Copenhagen; the top three countries/regions in the volume of literature were the United States (176 papers), Germany (64 papers) and France (54 papers), and they all co-operated closely with other countries. The top five keywords were "blood donor" , "prevalence" , "infection" , "risk" and "antibody" . A total of 19 clusters were obtained by keyword cluster analysis, it was reflected in the immune mechanism and prevalence of blood-borne diseases, the relationship between blood donation behavior and non-communicable disease and its influencing factors, and the classification of the characteristics of blood donors. "Non-hepatitis B" was the keyword with the greatest burst intensity. The keywords that have burst out in recent years and continue to this day include "donation" , "seroprev-alence" , "donor" and "management" . Conclusion At present, the cohort study of blood donors has been paid more and more attention in the world, and its research trends mainly focus on the study of transfusion-transmitted disease risk. However, more researches begin to pay attention to the health problems and influencing factors of blood donors or recipients, which provides the research ideas and directions for establishing cohort study among blood donors in China.
