The financial compensation mechanism for public county hospitals are discussed and analyzed in the paper.Such a mechanism is analyzed by means of media coverage and literature consulting,along with field survey.Roadblocks have been found in implementation of the mechanism, namely delayed payment of capital expenditure compensation,poor support for medical equipment purchase,gaps in development key disciplines development,insufficient compensation for retirees expenses,poor definition of policy-incurred losses,and unclear compensation of public health services.in a word,it is imperative to change the unreasonable financial compensation mechanism,before the six financial compensation subsidies can be fully put in place and financial compensation made efficiently.

The paper analyzed the compensation mechanism applied in public hospitals in different localities in China,which are currently experimenting with the zero price margin for drugs.It also introduced the revenue variations resulting from this practice.It is discovered that public hospitals can hardly make their ends meet with merely governmental financial input,and that lowered income of doctors and price distortion arc evident in those experimental hospitals,with little progress in overcoming the subsidization of medical services with drug sales.The authors recommended a comprehensive reform,the mechanism of diversified health input,change of internal incentive mechanism within the hospital,improvement in the healthcare service pricing mechanism,and exploration of new operation mechanisms for public hospitals.

Given the significant improvement in terms of its coverage and compensation depth,China's basic medical insurance system has inherent setbacks in its structure as held by the authors.They hold that the medical insurance as the most important source of compensation for medical institutions,should further reform its structure of financing and reasonably raise the percentage of compensation; adjust the time reference and space reference for prepayment estimation such as the total prepaid amount; deepen supportive reforms for the payment manner.All these measures aim at minimizing impact of the payment control mechanism on routine medical activities and exploring diversified payment manners that are feasible.

Through analyzing documents of healthcare departments, this paper explored the public benefit nature of the medical and health sector from such aspects as culture, philosophy, management, ethics,economy, politics and society. Furthermore, it analyzed the commonweal in the healthcare reform documents,including the commonweal in public health and medical services,basic medical care and health services,public hospitals and medical and health services. Public hospitals were cited as examples for an in-depth review of the profound connotation of commonweal in the medical and healthcare sector.

The comprehensive establishment of the basic medical and health system with Chinese characteristics is key to the healthcare reform. Taking the basic medical and health system as the specific research object, this paper elaborated the system examples of various countries' health systems. It also, using the classic system theory as the theoretical research basis, defined the connotation of the basic medical and health system with Chinese characteristics and described such characteristics. The purpose is to lay a theoretical foundation for the development of such a system, and provide references for the healthcare reform and Healthy China initiative.

From the perspective of the government′s positioning of public hospitals, the basic problems of functional positioning of public hospitals are clarified. According to different positioning subjects, the positioning of public hospitals is divided into three categories: government positioning, social positioning and self-positioning. By analyzing the connotation of the positioning mechanism of public hospitals, the outstanding performance of the insufficient realization of the government′s positioning of public hospitals, and the influencing factors of the government′s positioning of public hospitals, this paper tries to provide a theoretical basis for formulating a scientific and comprehensive reform plan of public hospitals.

Objectives To investigate the epidemiological and clinical characteristics of dyslipidemia as well as its treatment and influence on accompanying diseases in impaired glucose status among inpatients. Methods A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day in 2004. The fasting blood glucose (FBG), lipid profiles, BMI, waist to hip ratio (WHR) and concomitant disorders of the first screen during the hospitalization period were recorded. Those who had FBG level from 5.6 to 6. 9 mmol/L and not been previously diagnosed diabetes (PDM) underwent oral glucose tolerance test (OGTF). Results Of the 8753 inpatients investigated, 1067 eases had complete medical records(CMR case) including PDM cases and previously non-diagnosed diabetes ones with FBG ≥ 5. 6 mmol/L. Of the previously non-diagnosed diabetes cases with FBG levels from 5.6 to 6.9 mmmol/L, 65.8% accepted OGTT. Of the CMR cases, 41.9% had PDM, 21.7% was newly diagnosed diabetes mellitus (NDM), 29. 1% had impaired glucose regulation (IGR) and only 7.3% had normal glucose tolerance (NGT). The TG levels in NDM and PDM group were higher than those in IGR and NGT group (P < 0.05, respectively). The HDL-C levels in IGR, NDM and PDM group were lower than those in NGT group (P < 0.05, respectively). Sixty-nine point six percent of the diabetes mellitus (DM) inpatients was accompanied with dyslipidemia and the rate was higher than those in NGT (56.4%) and IGR inpatients (52.5%, P <0.05, respectively). Only 22. 8% of the PDM inpatients underwent treatment of dyslipidaemia and just 3.4% achieved the target suggested by the guideline of ATP-Ⅲ. BMI was higher and waistline longer in the PDM and NDM inpatients than those in the NGT cases (P <0.05, respectively). Seventy-two point eight percent of the PDM inpatients was complicated with more than one type of vascular diseases. Nine point seven percent and 0. 2% of the NDM inpatients were tormented by diabetic nephropathy and diabetic retinopathy respectively. Conclusions More inpatients with accompany DM or IGR had concomitant dyslipidemia than those with NGT, which included hypertriglyccridemia, hypo-high-density lipoproteinemia and metabolic syndrome. Concomitant vascular diseases were more frequently found in PDM inpatients than in the others. Some of the NDM and IGT inpatients were complicated with microvascular diseases.

Objective:To investigate the regulatory effects of ring finger protein 43 (RNF43) on CD8 + T cell-mediated anti-tumor immune reaction in melanoma. Methods:RNF43 gene was over-expressed and knockdown in mouse melanoma cells line B16-OVA by lentivirus infection; In vivo proliferation of mouse melanoma cells line B16-OVA in the Lv-Ctrl-OE, Lv-RNF43-OE, Lv-Ctrl-KD and Lv-RNF43-KD groups was detected by subcutaneous tumorigenesis assay in mice, and the expression levels of CD8 + T cells perforin and interferon γ (IFN-γ) in tumor immune microenvironment of melanoma were detected by flow cytometry; The expression levels of β-catenin and programmed death-ligand 1 (PD-L1) mRNA in cells were detected by quantitative real-time PCR assay; The effect of RNF43 on the transcriptional regulation of PD-L1 was detected by dual-luciferase reporter gene assay. Results:Stable RNF43 over-expressing and RNF43 knockdown mouse melanoma cells lines Lv-RNF43-OE and Lv-RNF43-KD were successfully constructed. The results of subcutaneous tumorigenesis experiment in mice showed that the tumor mass of the Lv-RNF43-OE group was (0.08±0.06) g, which was significantly smaller than that of the Lv-Ctrl-OE group [ (1.04±0.52) g], with a statistically significant difference ( t=3.71, P=0.032) ; The tumor mass of Lv-RNF43-KD group was (1.94±0.29) g, with no statistically significant difference ( t=-1.70, P=0.164) compared with that of the Lv-Ctrl-KD group (1.15±0.74) g. The flow cytometry results showed that the fluorescence intensity of CD8 + T cell perforin in the Lv-RNF43-OE group was 9 034 ± 2 628, which was significantly higher than that in the Lv-Ctrl-OE group (3 847 ±1 637), with a statistically significant difference ( t=-3.35, P=0.015) ; The fluorescence intensity of CD8 + T cell perforin in the Lv-RNF43-KD group was 966±247, which was significantly lower than that in the Lv-Ctrl-KD group (2 226±646), with a statistically significant difference ( t=3.16, P=0.034) ; The fluorescence intensity of IFN-γ of CD8 + T cell in the Lv-RNF43-OE group was 2 422±429, which was significantly higher than that of 1 688±324 in the Lv-Ctrl-OE group, with a statistically significant difference ( t=-2.73, P=0.034) ; The fluorescence intensity of IFN-γ of CD8 + T cell in the Lv-RNF43-KD group was 614 (454, 863), with a statistically significant difference ( Z=-1.96, P=0.050) compared with 1 159 (1 152, 2 068) in the Lv-Ctrl-KD group. The results of quantitative real-time PCR showed that the relative expression level of β-catenin mRNA in the Lv-RNF43-OE group was 0.67±0.16, which was significantly lower than that of 1.00±0.11 in the Lv-Ctrl-OE group, with a statistically significant difference ( t=2.98, P=0.041) ; The relative expression level of PD-L1 mRNA in the Lv-RNF43-OE group was 0.32±0.09, which was significantly lower than that of 1.00±0.09 in the Lv-Ctrl-OE group, with a statistically significant difference ( t=9.13, P=0.001). The results of the dual-luciferase reporter gene assay showed that the PD-L1 promoter luciferase activity in the pCMV6-NC, RNF43, RNF43+β-catenin and β-catenin groups were 1.00±0.00, 0.84±0.00, 1.49±0.00 and 1.57±0.03 ( F=2 218.33, P<0.001). Further pairwise comparison showed that compared with the pCMV6-NC group, PD-L1 promoter luciferase activity was significantly lower in the RNF43 group ( P<0.001) and significantly higher in the RNF43+β-catenin and β-catenin groups ( P<0.001; P=0.003) ; compared with the RNF43 group, PD-L1 promoter luciferase activity was significantly higher in the RNF43+β-catenin group ( P<0.001) . Conclusion:RNF43 may reduce the expression of PD-L1 mRNA in melanoma by inhibiting the expression of β-catenin and promote CD8 + T cell-mediated anti-tumor immune reaction.
