RESUMO
Objective:To investigate the effect of Asarinin on the survival time of transplanted heart after allogeneic heterotopic heart transplantation and to further verify the anti-immune rejection effect of Asarinin in spleen and peripheral blood.Methods:Using 64 Wistar rats as donors, 64 SD rats as recipients to establish the allogeneic heterotopic heart transplantation model in rats.After successful transplantation, 64 rats were use simple randomization divided into control group, cyclosporine A(CsA) group, Asarinin group and half CsA + half Asarinin group with 16 rats in each group.CsA group was given 5 mg/kg by gavage; Asarinin group was given 25 mg/kg; half dose group was given CsA 2.5 mg/kg+ Asarinin 12.5 mg/kg and the control group was given the same volume of normal saline by gavage.After administration for 1 week, half of them were used to observe the survival time.The other half of the rats were fully anesthetized with chloral hydrate, spleen and peripheral blood were taken.Half of the spleen was taken to observe the slices under the microscope.The other half of spleen was used RT-PCR to detect the relative expression of IFN-γ and IL-4.The expression of co-stimulatory molecules CD80, CD86 and CD40 in peripheral blood were detected by flow cytometry.Results:Survival time of transplanted heart was control group (8.4±0.9), CsA group (30.5±8.3), Asarinin group (16.5±4.3) and half-dose group (26.1±5.2) days.Compared with control group, survival time of heart transplantation became prolonged in all groups and the difference was statistically significant ( P<0.05). HE staining of splenic tissue showed that, as compared with control group, the injury of each group was alleviated.The relative expression of IFN-γ in spleen was control group (1.055±0.083), CsA group (0.396±0.038), Asarinin group (0.833±0.094) and half-dose group (0.862±0.104). The last three groups were lower than control group and the difference was statistically significant ( P<0.05). The relative expression of IL-4 in spleen was control group (1.429±0.234), CsA group (3.808±0.729), Asarinin group (2.209±0.306) and half-dose group (2.323±0.321). The last three groups all spiked as compared with control group and the difference was statistically significant ( P<0.05). The expressions of CD80, CD86 and CD40 in peripheral blood were control group (98.21±0.54), (85.78±0.89) and (96.36±0.66), CsA group (89.26±0.36), (56.86±2.32) and (88.11±1.61), Asarinin group (94.19±0.47), (79.01±1.12) and (87.86±1.67) and half-dose group (94.87±0.74), (80.81±0.98) and (89.71±0.97) respectively.The last three groups were lower than control group and the difference was statistically significant ( P<0.05). Conclusions:Asarinin can prolong the survival time of transplanted heart after allogeneic heterotopic heart transplantation in rats, inhibit the immune injury of spleen after allogeneic heterotopic heart transplantation in rats, decrease IFN-γ in spleen, increase IL-4 in spleen and inhibit the expression of peripheral blood costimulatory molecules CD80, CD86 and CD40.
RESUMO
Objective@#To investigate the healthcare expenditures and self-payment among patients with lung cancer in Wenling City before and after implementation of diagnosis-related groups (DRGs), so as to provide the evidence for controlling medical costs and relieving burdens of patients with lung cancer. @*Methods@#The basic data and healthcare expenditures of lung cancer patients that were definitively diagnosed from 2015 to 2019 and covered by medical insurance were captured from the cancer registration database of Wenling Center for Disease Control and Prevention and the database of chronic and specific diseases in Wenling Bureau of Medical Insurance. The changes of outpatient expenditures, inpatient expenditures and self-payments were compared before (2015-2016) and after implementation of DRGs (2018-2019) among lung cancer patients.@*Results@#Totally 4 947 lung cancer patients covered by medical insurance were enrolled in this study, including 3 052 males (61.69%) and 1 895 females (38.31%), with a mean age of (64.88±11.64) years. The annual mean healthcare expenditure was 56 675.85 Yuan per capita during the period between 2015 and 2016, in which 14.48% were outpatient expenditures and 85.52% were inpatient expenditures, and the annual mean healthcare expenditure was 38 702.94 Yuan per capita during the period between 2018 and 2019 (a 31.71% reduction as compared to that in 2015 and 2016), in which 24.49% were outpatient expenditures and 75.51% were inpatient expenditures. The proportions of outpatient expenditures, inpatient expenditures and total self-payments consisted of 25.38%, 32.49% and 29.67% of total healthcare expenditures in 2018 and 2019, which were significantly lower than those (50.84%, 50.96% and 50.95%, respectively) in 2015 and 2016 (χ2=13.741, P<0.001; χ2=7.015, P=0.008; χ2=9.340, P=0.002).@*Conclusions@#The annual mean healthcare expenditures per capita and the proportion of self-payment reduce among lung cancer patients covered by medical insurance following implementation of DRGs.
RESUMO
Objective:Based on the perspective of status-seeking, to clarify the status quo of rural doctors′ subjective social status, and put forward countermeasures and suggestions to improve the subjective social status of rural doctors.Methods:By investigating 1 395 rural doctors in both 2015 and 2017 to clarify the status quo of rural doctors′ subjective social status through descriptive analysis, we compared the subjective social status of rural doctors with different characteristics by using differential analysis.Results:The overall subjective social status scoring of rural doctors was 3.17±0.48, including decision participation scoring(3.30±0.82), income scoring(2.19±0.80), social relationship scoring(4.05±0.61), career reputation scoring(3.09±0.84), career promotion scoring(2.38±0.67), and career value scoring(4.04±0.63). Rural doctors with middle or above academic titles, high-performance levels, as well as those comparable to doctors in township hospitals and self-employed clinics were found with higher subjective social status.Conclusions:Rural doctors held their subjective social status to be at an intermediate level, with higher ratings for interpersonal relationships and professional values and lower ratings for salary and training mechanisms. Positive feedback on the status-seeking behavior of rural doctors is recommended to improve village clinic services and reshape the image of rural doctors.
RESUMO
The healthcare plus aging care is a new type of aging care model that integrates medical services and aging care services. China has successively issued a series of policies, encouraging the localities to proactively explore such a model. The authors refer to the four dimensions of exchange and communication, policy resources, policy executor preferences and organizational structure in the Edwards policy execution model, for analyzing the implementation of such a policy. The study found such constraints for the policy as follows: unclear policy implementation standards, inadequate policy resources of manpower, financial and material resources, differences in preferences among local governments, general hospitals, primary medical institutions, and pension institutions, as well as decentralized and restricted organizational structures. At present, the policy of healthcare plus aging care remains in the stage of exploration and trial. The government should continue to define and revise the policy to ensure the smooth progress and long-term implementation of the policy of healthcare plus aging care.
RESUMO
Family physicians contracted service is an important choice to deepen the reform of China′s healthcare reform and achieve the strategic goal of " health for all" . In order to effectively promote the contracted service, the central government has successively issued a number of policy documents, which are echoed by the localities in their proactive explorations, achieving remarkable results. But there are also multiple roadblocks hindering the contracted service to progress. This article referred to the three-circle theory and studied policy implementation from the three dimensions of policy value, policy resources, and policy impetus. A thorough analysis of the problems in the implementation process revealed such main problems as insufficient family physicians, inadequacy of supporting policies and low level of policy acceptance among the young healthy age groups. The follow-up work will promote the long-term implementation of the family physicians contracted service policy by enriching the family physicians team, enriching supporting policies, and focusing on promotions to key age groups.
