[Objective] To explore the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou, and to investigate the correlation between donation frequency and these factors. [Methods] A cross-sectional study was conducted among 13 042 whole blood donors from 17 street blood donation sites of Guangzhou Blood Center from May to August 2020. Descriptive analysis was used to describe the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou. Ordinal multinomial logistic regression model was used to analyze the correlation between donation frequency and these factors. [Results] It was found that some of 13 042 blood donors had unhealthy habits, such as 6.8% (698/10 214，2 828 missing values) had severe tobacco dependence, 30.6% (3 997/13 042) had low exercise levels, 38.8%（5 056/13 042）had poor sleep quality, and 2.2% (271/12 159，883 missing values) had alcohol dependence. In addition, 2.8% (364/13 042) and 1.3% (172/13 042) of the donors may have moderate to severe depression and anxiety symptoms, respectively. The results of the ordinal multinomial logistic regression model showed that exercise level was significantly negatively correlated with the degree of depression and anxiety among blood donors. With the decrease in exercise level, the possibility of depression and anxiety among donors increased significantly. BMI, household income, education level, marital status, donation frequency, alcohol consumption and smoking had no significant correlation with the mental health status of donors. [Conclusion] Improving the exercise habits of blood donors may help enhance their mental health level. It is recommended that blood station staff strengthen the content of exercise when providing health education to blood donors to maintain a healthy lifestyle. It also suggests that there may be a certain degree of under-diagnosis of mental health problems in the process of health consultation before blood donation, and conducting more comprehensive and effective mental health assessments for blood donors is recommended.

Objective To explore the value of pelvic CT angiography(CTA)digital three-dimensional reconstruction model(abbreviated as"three-dimensional model")in the diagnosis of female pelvic mass.Methods A total of 98 patients with pelvic mass who were hospitalized and operated in Xi'an People's Hos-pital(Xi'an Fourth Hospital)from January 2021 to April 2023 were selected.All patients underwent B-ultra-sound and CTA examination before operation,and the original data of CTA were collected.The digital three-dimensional model of pelvic mass was established by three-dimensional reconstruction software,and the source of pelvic mass was judged according to the blood supply of pelvic mass.Taking postoperative pathological di-agnosis as the gold standard,the coincidence rate between different preoperative diagnosis methods(B-ultra-sound,CTA examination and three-dimensional model)was compared.The receiver operating characteristic(ROC)curve was plotted to evaluate the efficacy of different preoperative diagnostic methods in judging the ovarian origin of pelvic tumors.Results A total of 130 pelvic masses were included in 98 patients,and the average maximum diameter of the mass was(71.61±3.03)mm,including 83 ovarian masses and 47 non-ovarian masses.Taking postoperative pathological diagnosis as the gold standard,the diagnostic coincidence rate of the preoperative three-dimensional model was 72.31％,which was higher than that of B-ultrasound(58.46％)and CTA(52.31％),and the differences were statistically significant(P＜0.001).The sensitivity,specificity,positive predictive value,negative predictive value,accuracy,Kappa value,and area under the ROC curve were 79.51％,91.49％,94.29％,71.67％,83.85％,0.67 and 0.855,respectively,when the three-dimensional model showed that the blood supply of the mass originated from ovarian artery or uterine artery-ovarian branch.Conclusion The three-dimensional model of pelvic CTA can directly display the blood supply source,characteristics of mass,and the relationship between mass and adjacent organs,which can guide the clinical treatment.It has certain clinical value to judge the ovarian origin of pelvic mass by using ovarian artery and uterine artery-ovarian branch.

【Objective】 To investigate the prevalence of depression in blood donors and analyze the related factors, so as to develop a rapid depression screening model for blood donors. 【Methods】 A total of 13 015 street whole blood donors in Guangzhou Blood Center during May to August, 2020 filled in an anonymous e-questionnaire, including social demography information and the Patient Health Questionnaire-9 before donation. The cut-off value for detecting depression was 10. Logistic regression by SPSS 26.0 was used to analyze depression related factors. 2-level decision tree with 30/10 as the minimum number of cases in parent/child node, 10-fold cross validation was used to cut items of PHQ-9 to form the depression screening model. 【Results】 364 out of 13 015 (2.80%) street whole blood donors reported a score ≥ 10. Donors with 18-29 years old (P <0.05), unmarried (P<0.05), less than 50 000 RMB household income per year (P< 0.05) were more prone to depression. 81.96% donors in "<10 scores" group, while 3.85%donors in "≥ 10 scores" group were in two terminal nodes formed by Item-6, 2 and 4 of PHQ-9. After verification by the 10 fold crossover method, the estimated misclassification risk of the model was 1.7%. 【Conclusion】 The screening prevalence of depression based on PHQ-9 in Guangzhou blood donors was 2.8%(95% CI: 2.52%-3.09%) . Donation frequency was not related to depression. A rapid and efficient depression screening model for blood donors based on item-6, 2 and 4 of PHQ-9 was developed.

Objective:To analyze the experiences and practice in the reform of public hospital salary system in Sichuan province, summarize the typical modes of such reform in the province, and provide references for further reform.Methods:As of October 29, 2021, the research group received 77 sets of typical experience materials submitted by the health commissions and public hospitals in Sichuan province on enforcing the reform of the public hospital salary system. The analysis framework was based on the five main elements proposed in the Guidance to Deepening the Reform of the Salary System of Public Hospitals for the purpose of furthering the reform. These five elements refer to " reasonably determining the level of salary in public hospitals" " fully implementing the autonomy of internal distribution in public hospitals " " establishing and improving the incentive and restraint mechanism for the remuneration of public hospital leaders" " improving the assessment and evaluation mechanism oriented to public welfare" and " funding sources ". A quantitative analysis was made on the typical experience materials using the social network analysis method, while a qualitative analysis was made on the typical experience materials using the content analysis method. Results:The results of social network analysis showed that the network density was 0.272; the highest point centrality was " fully implement the autonomy of internal distribution in public hospitals" (0.935), and the highest intermediary centrality was " improving the assessment and evaluation mechanism oriented to public welfare" (0.870), while the closeness to centrality of " establishing and improving the incentive and constraint mechanism for the salary of public hospital leaders" (0.434) and " funding sources" (0.421) were relatively low. The results of content analysis showed that the ones with higher frequency among all the typical experience materials were " fully implementing the autonomy of internal distribution of hospitals" (72 times) and " improving the assessment and evaluation mechanism oriented to public welfare" (67 times), while the ones with lower frequency were " establishing and improving the salary incentive and constraint mechanism for public hospital leaders" (17 times) and " funding sources" (14 times). In terms of unity and synergy, the typical models of public hospital salary system reform in the province could be categorized as the fine standard mode, the fair value mode, the autonomous synergy mode and the circular symbiosis mode.Conclusions:Deepening the reform of the salary system of public hospitals should unify the standards and improve the fair and refined assessment and evaluation mechanism; explore various forms of distribution and build an internal autonomous and synergistic incentive mechanism; pay attention to the weak remuneration incentive mechanism for hospital leaders and the problem of a relatively single source of funding.

Objective:To analyze the salary characteristics of medical institutions and the influencing factors of personnel expenditure as found in the salary system reform of public hospitals in Sichuan province, for reference in furthering such reform in public hospitals.Methods:The data of personnel expenditure, business operation and medical services came from 96 medical institutions in 21 cities(prefectures)of Sichuan province from 2017 to 2020 by means of institutional survey. The average salary level and salary structure of medical staff were used to describe the salary characteristics, and the total salary was presented by the level of personnel expenditure. The measurement data was represented by M(IQR), the counting data was described by frequency and constituent ratio, and the influencing factors of personnel expenditure were analyzed by generalized linear mixed model. Results:From 2017 to 2020, the personnel expenditure of medical institutions increased by 13.04% annually. In 2020, the per capita salary level of medical staff was 151 900 yuan, while the basic salary and performance salary accounted for 16.20% and 54.60% of personnel expenditure respectively. The analysis results of the generalized linear mixed model showed that the average cost of patients per visit( β=0.596), the level of drugs and sanitary materials consumed per 100 yuan medical income( β=0.286), the number of medical visits( β=0.328), and the years [(2018, 2019, 2020) β=0.025, 0.052, 0.066] were positively correlated to personnel expenditure, while the average length of stay( β=-0.693), the proportion of medical service income( β=-0.392), and the balance rate of income and expenditure( β=-0.062)were negatively correlated to personnel expenditure( P<0.05). The proportion of fiscal subsidy revenue, regional GDP and asset-liability ratio were not the influencing factors of personnel expenditure( P> 0.05). Conclusions:In the reform of the salary system of the province, its salary level of medical institutions has surpassed the current wage ceiling of these institutions. As the salary distribution was mainly made based on the workload, the " baton" role of the salary system reform has begun to pay off. However, the basic guarantee role of compensation has not yet been fully leveraged.Further reform is needed in upgrading refined management, and timely dynamic adjustment of personnel expenditure in combination with the hospital's financial performance and cost analysis, and reasonably optimizing the level of medical staff compensation.

Objective:To analyze the staff salary status and the influencing factors in traditional Chinese medicine(TCM) hospitals implementing the salary system reform in Sichuan province in 2020, for reference in optimizing the salary system reform of such hospitals.Methods:Cluster sampling and institutional survey were used to collect the salary information of 26 TCM hospitals in 21 cities(prefectures)of Sichuan province implementing the salary system reform in 2020. Such information was then subject to descriptive analysis, while the influencing factors of salary were subject to one-way analysis of variance and generalized linear model multifactor analysis.Results:15 428 staff from 26 TCM hospitals were included as the research objects. In 2020, personnel expenditure accounted for 40.23% of the total expenditure, and 24.34% of which came from financial subsidy in 26 TCM hospitals. The average annual payable income per person was(149 312±74 288)yuan, 67.82% of which being performance pay. Analysis of variance showed that there were significant differences among the salary levels of staff in different economic regions, hospital grades, hospital levels, gender, educational background, position, seniority, performance pay ratio, employment in the government system and other natures, senior and other professional titles, doctors and other positions( P<0.05), and the differences were still statistically significant after adjustment by generalized linear model( P<0.05). Conclusions:The reform of the salary system of Sichuan TCM Hospitals has basically achieved equal pay for equal work, and the income of low-level personnel has been improved. However, the salary level was not very motivated and the salary structure was not guaranteed. It is necessary to strengthen financial precision subsidies, increase the proportion of personnel expenditure, so as to support the increase of the absolute value of salary in non-core economic areas, improve the salary structure, reasonably widen the salary gap among different educational backgrounds and positions, further optimize internal distribution, and ensure the sustainable development of Chinese medicine talents.
