This paper described the measures taken by Sir Run Run Shaw Hospital of Zhejiang University School of Medicine in development of general medicine,and differential care of acute and chronic diseases. Rational allocation of medical resources and leveraging of tertiary hospital′s advantages in medicine and education effectively improved the utilization ratio of medical resources for better health of the people.

The experience of various countries proves that the hierarchical diagnosis and treatment model can lead to reasonable resources allocation and utilization, however, the waste of China''s disordered treatment model has not been estimated.Nowadays, it is very important to establish a hierarchical diagnosis and treatment system during China''s healthcare system reform.Therefore, it is necessary to estimate the benefit the reform may bring.We take Zhejiang Province as an example, and adopted the system dynamics model to build the health delivery system, to emulate the hierarchical diagnosis and treatment model and the disordered model, and to evaluate the benefit.Results showed that if first option at the primary health institutions increased 10%, it could save 0.251 billion yuan, and if increased 15%, it could save 0.39 billion yuan.If the first option at the primary health institution reached 72.35% and the treatment in county reached 90%, the outpatient in tertiary hospital could reduce by 13 million, and those in primary healthcare institutions could increase by 74 million yuan.The direct healthcare cost could reduce 3.016 billion Yuan.

With its excellent biocompatibility,good biomechanics and biodegradability,magnesium zinc alloy has been widely used in biomaterials,and its antineoplastic effect has attracted more and more attention recently.Osteosarcoma is the most common primary malignant bone tumor.With the improvement of the diagnosis and treatment,the rate of 5-year survival has been greatly improved,which is nearly 60％ ～ 70％.However,local recurrence and metastasis after operation are still main risk factors on the survival quality and clinical function of patients.This paper reviews previous researches concerned the antineoplastic effect about magnesium,zinc and its alloys,and summarized the anti-tumor mechanism of magnesium,zinc and its alloys,and its research value in the field of osteosarcoma.

This paper described the market reform′s influence and the healthcare reform on medical behaviors of both doctors and patients.It is held that the healthcare reform should ensure the public welfare nature of public hospitals and focus on medical quality and patient′s health,so as to promote the harmonious development of the doctor-patient relationship from the policy and practice aspect.

Objective To analyze the impacts of bureaucracy management at tertiary public hospitals in Beijing on exchange modes and trust between doctors and patients, using both the bureaucracy theory and trust theory. To study the role of such management as an organizational structure for hospital operation and service, in the transition of doctor-patient trust from traditional special trust to a universal trust based on bureaucracy structure and specialized job division. Methods The purpose sampling method was used to select 94 hospital administrators, medical staff, and patients from six tertiary hospitals for a field survey. Results Bureaucracy at public tertiary hospitals keeps improving, and its systematic and refined organizational structure is changing the exchanges between doctors and patients, earmarking universal trust of the fundamental type of doctor-patient trust, aided by special trust. Rules and regulations of bureaucracy normalize medical services, and specialization enables medical workers in their clinical work against difficult and severe diseases, winning both reputation and patient trust as well. However, the specialized, professional and dehumanized characteristic of bureaucracy tend to encourage doctors to attend to diseases than patients, and separate links in medical services to decrease doctor-patient trust in the meantime. Conclusions Bureaucracy is a necessary organizational form of urban public hospitals, but it should strengthen their humanity feature and improve their communication with patients with rules and regulations. At the same time, with the use of integrated medical mode in clinical practice, bureaucracy could be improved to benefit patients and enhance trust of patients.

Objective: To evaluate the new compensation mechanism for primary healthcare institutions in Zhejiang province, in terms of fairness, performance, incentive mechanism and sustainability in pilot areas. Methods: Evaluation indicators were constructed based on stakeholder theory, fairness theory, expectation theory and sustainable development theory.Focus group interviews were conducted with stakeholders and quantitative data were collected through questionnaires. Meanwhile, the financial compensation, income and expenditure and work equivalent data were collected from such institutions of the four pilot areas, with quantitative data subject to descriptive analysis. Results: This study found the reform used reasonable proportion of funds allocated(the proportion of basic salary for employees was lower than 50%)and adjustment factors(1.0-1.8)of different primary healthcare institutions to guarantee the fairness of the reform; the increase of work equivalents(the per capita work equivalents of medical staff in pilot counties had increased from 38.435 million in the previous year to 42.590 million work equivalents)reflected the performance outcomes of the reform. The incentive and sustainability of the reforms were the weak parts. These were mainly due to the fact that the internal distribution system of primary healthcare institutions failed to make corresponding reforms. Conclusions The reform of the compensation mechanism based on the equivalent method has changed medical staff′s perception of the distribution of funds. The principle of" more pay for more work" and the use of information technology to capture work equivalents have improved the enthusiasm of primary medical staff and the operational efficiency of these institutions, thus, making reform generally scientific and reasonable.

With Jinhua Central Hospital as an example,merits and setbacks of the 3-level trusteeship model in practice were discussed,with improvement recommendations raised for progress of the hierarchical medical system.

Objective:To explore the mediating roles of rumination and avoidance coping between information anxiety and suicidal ideation.Methods:In March 2022, a total of 896 college students were surveyed by the information anxiety scale(IAS), ruminative responses scale(RRS), coping style questionnaire(CSQ)and self-rating idea of suicidal ideation scale(SIOSS). The ANOVA analysis, Pearson correlation analysis and mediating effect analysis were performed by the SPSS 22.0 software.Results:The detection rate of suicidal ideation among college students was 9.15%(82/896). The information anxiety score was(73.84±17.29), the rumination score was(47.73±12.16), the avoidance coping score was(3.76±2.52), and the suicidal ideation score was(5.41±4.09). Information anxiety was significantly positively correlated with rumination, avoidance coping and suicidal ideation( r=0.49, 0.36, 0.37, all P<0.05). Rumination was significantly positively correlated with avoidance coping and suicidal ideation( r=0.42, 0.59, both P<0.05). There was a significantly positive correlation between avoidance coping and suicidal ideation( r=0.45, P<0.05). Information anxiety affected suicidal ideation of college students through four paths.The direct effect value of information anxiety on suicidal ideation was 0.06, accounting for 16.67% of the total effect. The effect values of the separate mediating effect of rumination and avoid coping were 0.22 and 0.04, and accounting for 61.11% and 11.11% of the total effect respectively. The chain mediating effect value of rumination and avoid coping was 0.04, accounting for 11.11% of the total effect. Conclusion:Information anxiety can directly affect suicidal ideation of college students and indirectly affect suicidal ideation through rumination and avoidance coping.

Objective:To discuss the damage effect of vesicular stomatitis virus(VSV)on the vascular endothelial(VE)barrier,and to clarify its mechanism.Methods:The canine kidney cells were used to amplify VSV.The half tissue culture infective dose(TCID50)of VSV was determined using mouse brain endothelial tumor bEnd.3 cells,and subsequent experiment was conducted using 300 times the TCID50.The bEnd.3 cells were divided into infection 0 h group,infection 4 h group,infection 8 h group,and infection 12 h group for VE barrier damage experiments due to VSV infection.The bEnd.3 cells were also divided into control group,infection group,and correction group for experiments to inhibit the VSV replication and restore the VE barrier.The bEnd.3 cells were inoculated into Transwell chambers to construct an in vitro VE barrier model.Cell voltage resistance meter was used to detect the transepithelial resistance(TER)in various groups after the bEnd.3 cells were infected with VSV at different time points;fluorescein isothiocyanate-dextran leakage assay was used to detect the permeability coefficients of the cells in various groups;immunofluorescence staining was used to observe the localization changes of VE-cadherin,β-catenin,and phosphorylated β-catenin(p-β-catenin)in cytoskeleton and adherens junctions(AJs)of the bEnd.3 cells after VSV infection;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of Wnt and β-catenin mRNA in the cells in various groups;Western blotting method was used to detect the expression levels of Wnt,β-catenin,and p-β-catenin proteins in the cells in various groups.Results:The TCID50 of VSV was 10-4.5·100 μL-1.TheTranswell chamber experiment results showed that compared with infection 0 h group,the TERs in the cells in the other groups were significantly decreased(P＜0.05),and the permeability coefficients were significantly increased(P＜0.05).The immunofluorescence staining results showed that compared with control group,the cytoskeleton of the bEnd.3 cells in infection group was disordered,the cell gaps was increased,the linear index of AJs was significantly decreased(P＜0.05),and β-catenin and p-β-catenin translocated from the cell membrane to the perinuclear area.The RT-qPCR results showed that compared with infection 0 h group,the expression levels of Wnt mRNA in the cells in the other groups were significantly decreased(P＜0.05),while the expression levels of β-catenin mRNA showed no statistically significant difference(P＞0.05).The Western blotting results showed that compared with infection 0 h group,the expression levels of Wnt protein in the cells in the other groups were significantly decreased(P＜0.05),the expression levels of β-catenin showed no statistically significant differences(P＞0.05),and the expression levels of p-β-catenin were significantly increased(P＜0.05).After inhibiting the VSV replication and correcting the low density lipoprotein receptor(LDLR)abnormalities,the Transwell chamber experiment results showed that compared with infection group,the TER in the cells in correction group was significantly increased(P＜0.05),and the permeability coefficient was significantly decreased(P＜0.05).The immunofluorescence staining results showed that compared with infection group,the gaps in the cells in correction group were reduced,and the perinuclear aggregation of β-catenin and p-β-catenin in the cells was restrained.The RT-qPCR results showed that compared with infection group,the expression level of Wnt mRNA in the cells in correction group was significantly increased(P＜0.05).The Western blotting results showed that compared with infection group,the expression level of Wnt protein in the cells in correction group was significantly increased(P＜0.05),the expression level of β-catenin showed no statistically significant difference(P＞0.05),and the expression level of p-P-catenin was significantly decreased(P＜0.05).Conclusion:VSV infection can cause the LDLR inactivation,reduce the expression level of Wnt protein,increase the phosphorylation level of β-catenin and cause its internalization,disrupt the stability of AJs,and ultimately lead to VE barrier damage.
