Objective To study the anti-duck hepatitis B virus (DHBV) action of limax polysaccharide. Methods 1-day old Beijing ducklings with congenital infection of DHBV were used as the animal model and were days. The expression of DHBV-DNA was detected by dot-blot hybridization test before treatment, five days and ten days after treatment. Results After medicated with Limax polysaccharide for five days and for ten days. The optic density value(OD value) of DHBV-DNA in ducklings serum were obviusly lower than that before treatment. There was significant difference between them. The inhibition rote of limax polysacchatide compared with the model group is markedly improved. Conclusion Limax polysaccharide can protect duck liver against inflammation by the inhibition of DHBV.

Objective Measure the variation trend and the problems of bed allocation and its equity at primary medical institutions and provide theoretical basis for optimizing the policy of health resources allocation for the government.Methods Analysis of the distribution and equity of the inpatient beds at primary medical institutions in terms of geographical area by means of the survey of regular overall statistics forms and the methods of Gini coefficient and Theil index.Results From 2009 to 2012,the number increase of beds at such institutions geographically was 7.72%,while that in eastern,central and western regions of China were respectively 5.35%, 3.97% and 27.88%.The number increase at community healthcare centers was 46.58%,while that in eastern,central and western regions of the country were respectively 18.09%,29.57%和 81.53%.The number increase at township hospitals was 2.33%,while that in eastern,central and western regions were respectively - 3.83%,- 0.43% and 22%.The Gini coefficient of bed allocation at such institutions was beyond 0.6,while that in eastern, central and western regions were respectively under 0.3,0.3-0.4 and 0.6 above.The Gini coefficient of bed allocation at community healthcare centers fell from above 0.4 to under 0.4.The Gini coefficient in the western regions increased from 0.3-0.4 to over 0.4.The variation trend of township hospitals was similar with the overall conditions at such institutions.The intra-regional Theil indexes and their contribution rates of bed allocation at such institutions were higher than those of inter-regional. Conclusions The overall variation trend of bed allocation at such institutions was on the rise,yet its variation trend of equity remains unchanged.The bed allocation and its equity at such institutions were higher than those at township hospitals.The growth rate in western regions was the highest,but the absolute number was the lowest.Moreover,the equity of bed allocation in such regions was not only the lowest,but also was found rising.The influence of bed allocation in intra-region terms was large,while its equity was not only lower but falling as well.

Following an analysis of the problems and challenges of hospitals regulation in China and a comparative study of situations at home and abroad,this paper presented six policy proposals for the reform of public hospitals regulatory system in China.The policy suggestions included definite regulatory objectives,defined relationship between public hospitals and government,strengthening both economic regulation and social regulation, establishing multivariate regulatory system, introducing flexible regulatory methods and full utilization of the third-party impact,which met the requirements of public hospital in healthcare reform in China and propelled the reform forward.

Objective The infection of hepatitis B virus(HBV),which is a hepatotropic DNA virus,can cause acute or chronic viral hepatitis and further may develop liver fibrosis,cirrhosis and even hepatocellular carcinoma. In recent years,with the establishment of HBV transfection cell and animal models,the anti -hepatitis B virus effect of ingredients extracted from many traditional Chinese medicine has been proved.Therefore,chemical composition extracted from the resourceful library of traditional Chinese medicine,with high efficiency and low toxicity,might be the direction for developing anti -hepatitis B virus medicine.

Objective:To measure the salary satisfaction level of medical staff in county-level public hospitals and provide reference for the design of policy reforms. Method:Eight county-level public hospitals were investigated. All analyses were performed using SPSS 19. 0 via statistical description and binary logistic regression. Results: The total salary satisfaction of the medical staff was 48 . 8%, and the average score was 54 . 05 ± 18 . 04 . The welfare satis-faction is the lowest (38. 8%), and the average score is 7. 98 ± 3. 51. Logistic regression analysis shows that the ac-ademic degree, department category, working hours per week, acceptance of bribes, and officially budgeted posts are the main factors affecting overall compensation satisfaction. Conclusion:The overall salary satisfaction level of medi-cal staff in county-level public hospitals is very low, and the welfare satisfaction is the lowest. Establishing the rea-sonable level of compensation, the rise of compensation, and the welfare mechanism are feasible choices to improve salary satisfaction.

Objective:Based on the current medical environment, to learn about cognition status of doctor-patient relationship among medical students and analyze causes of the tension between doctors and patients.Methods:Using the self-designed questionnaire "Clinical Medical Students' Cognition Survey on Occupational Status and Doctor-Patient Relationship", a cross-sectional survey was conducted on 527 medical students from 5-year and 7-year clinical program in Batch 2014 in a medical university in Heilongjiang Province. The survey mainly analyzed the causes of the tension between doctors and patients from the level of medical staff, patients and their families, hospitals and society. SPSS 22.0 was used for descriptive statistics and chi-square test.Results:The results showed that 93.7% of the medical students believed that the current doctor-patient relationship was not harmonious. There were cognitive differences among medical students in different gender ( P=0.029), first contact clinical grade ( P=0.003) and professional identity ( P<0.001). Conclusion:Medical students have a poor evaluation towards the current doctor-patient relationship. In order to construct harmonious doctor-patient relationship in the future, we can try to take measures such as carrying out relevant courses of doctor-patient communication, improving the medical students' communication skills and enhancing their professional identity.

Objective: To explore mechanism of how nurse managers' transformational leadership affects patient satisfaction, and to examine the mediating role of nurses' psychological empowerment. Methods: A total of 140 nurses and 310 patients in Sun Yat-sen University Cancer Center were surveyed. The Leadership Practice Inventory-other, the Psychological Empowerment Scale and two items from the Hospital Consumer Assessment of Healthcare Providers and Systems Survey (Chinese version) were used to measure nurse-perceived nurse managers' transformational leadership behaviors, nurses' psychological empowerment and patient satisfaction. The descriptive statistics and correlation analysis were performed using the SPSS 20.0. software package, and the structure equation modeling was performed using the MPlus 7.0. Results: Higher frequencies of nurse managers adopting transformational leadership were associated with higher level of nurses' psychological empowerment (β=0.665, P < 0.05); higher level of nurses' psychological empowerment was associated with higher overall patient satisfaction (β=0.243, P < 0.05); nurses' psychological empowerment mediated the relationship between nurse managers' transformational leadership and patients' overall satisfaction (β=0.162, P=0.014); the effects of nurse managers' transformational leadership and nurses' psychological empowerment on patients' recommendation of hospital were not statistically significant (P>0.05). Conclusions Nurse managers are encouraged to adopt transformational leadership, i.e., improving clinical and leadership skills, trying to be nurses' role model, solving problems at work, empowering and motivating nurses, thus to increase nurses' senses of empowerment, and to improve patient satisfaction eventually.

【Objective】 To analyze the implementation and problems in the process of the first policy of serious illness benefits for voluntary blood donors in China, therefore provide reference for other provinces and cities to formulate care policies for voluntary blood donors. 【Methods】 The number of blood donors who received serious illness benefits and the proportion to the total number of blood donors in that year were obtained by Excel, and their basic demographic information, illness and reasons for failing to receive benefits were analyzed. 【Results】 From 2015 to 2019, a total of 198 blood donors applied for serious illness benefits, and 159 received benefits (638 000 yuan), accounting for 0.017% of the total number of voluntary blood donors in Nanjing. The average age of the recipients was 52.66, with the proportion of males (63.5%) higher than that of females (36.5%). 52.8% (the highest proportion) got benefits of 5 000 yuan. 39 applicants failed to obtain serious illness benefits, among which 27 applicants failed during 2017 to 2018 due to unidentifiable funding source. But after Nanjing Blood Donation Regulations clarified the funding sources, the implementation of serious illness benefits policy was continued in 2018. 【Conclusion】 The implementation of serious illness benefits for voluntary blood donors presented the Nanjing municipal government's care for voluntary blood donors. The legalization of this policy is conducive to the continuity and stability of policy implementation. Relevant departments and blood centers should continue to strengthen the policy publicity and make sure the policy is implemented effectively.
