Chinese Medical Ethics 1995;0(02):-
There are serious moral hazards in medical insurance because of information asymmetry.Moral hazards can make different degree influence on the medicare supply,demand and supervision of usage.From the 1960s,scholars have much research and discussion on the different main body that be of moral hazard,on the influence of moral hazard to welfare,on the measure of moral hazard and on the methods that how to control moral hazard.This paper summarizes the related viewpoints and conclusions that come from the above four aspects.
3.The Price Regulation of Medical Service:Theoretic model and reform trends in China
Chinese Health Economics 2013;(7):29-31
Objective: To explore the medical service price regulation of theoretic model and reform trends in China. Methods:Qualitative method. Results:Medical care is the service that mix the nature of public service and private service. The price regulation of medical care includes the regulation of price level and price structure. The asymmetric information, equality, externality and monopoly of the medical care are the reasons to implement the price regulation. Ramsey pricing model, investment rate of return pricing model, the price-cap model, yardstick price regulation model and Feldstein pricing model are the general models to implement the price regulation of medical care. Conclusion: China should reform and modify the current price level and structure of medical care based on the above models.

Objective To investigate the effects of chrysin(ChR) on the induction of differentiation and apoptosis-promoting of HepG 2 human primary hepatocacinoma cells. Methods The HepG 2 cells were cultured in vitro, and then treated with ChR and all-trans retinotic Acid (RA), respectively, the alterations of nucleocytoplasm and tubulin arrangement after Gimsa staining and Coomassie brilliant blue staining were observed. The survival rate and the inhibitory rates of HepG 2 cells were determine by trypan blue counting method and MTT assay. The Alpha-fetoprotein(AFP) secretory amounts of the cells were detected by radioimmunoassay(RIA). The activities of alkaline phosphatase(ALP) andγ-glutamyltranspeptidase(γ-GT) were assayed by enzymatic reaction kit. The synthesis of tyrosine-α-ketoglutaric acid transaminase(TAT) in cells were investigated by Diamondstone spectrophotometry. Results After treatment with ChR or RA at 1.0~100μmol/L for 48 h, the proliferation of HepG 2 cells were inhibited significantly, compared with vehicle group (P<0.05 or P<0.01), the inhibitory potency of both ChR and RA on HepG 2 cells was equivalent and indicated in dose-dependent manner. After treatment with 10μmol/L ChR or RA for 48 h, HepG 2 cells disaggregated and grew to spindle-shape, their nuclei became smaller and the number of nucleolus were fewer. Furthermore, tubulin arrangement of cells tended to be more ordered and the tubulin synthesis increased significantly. At 24~96 hours treated with 10μmol/L ChR, the activities of TAT and ALP in cells were all increased distinctly (P<0.05, P<0.01), and the secretory amounts of AFP and the specific activities ofγ-GT were decreased significantly (P<0.05, P<0.01). Conclusion Chrysin can inhibit the proliferation of HepG 2 cells and induce them to differentiate to mature cells.

AIM: To investigate the role of p38 mitogen-activated protein kinase (p38MAPK) signaling pathway in the Kupffer cells (KCs) production of pro-inflammatory cytokines, tumor necrosis factor-?(TNF-?) and interleukin-1?(IL-1?), in severe acute pancreatitis (SAP) rats. METHODS: Sprague-Dwaley rats were randomized into three groups: ①sham operation rats, ②SAP rats, ③SAP rats given the p38 MAPK inhibitor CNI-1493(10 mg/kg, iv). The SAP model was induced by the bili-pancreatic duct infusion with 5% sterile soduim taurocholate solution. Rats from each group were killed at 12 h after sham operation or SAP and Kupffer cells (KCs) were isolated. The mRNA expressions of TNF-? and IL-1? (by quantitative real-time RT-PCR) and p38 MAPK activity (by Western blot analysis) in KCs were examined. The levels of TNF-? and IL-1? in plasma were determined by ELISA. RESULTS: There was a significant acvitation of p38 MAPK in KCs harvested from SAP rats than those from sham operation rats. SAP also promoted the mRNA expressions of TNF-? and IL-1? in KCs and the plasma levels of TNF-? and IL-1?. These events were significantly inhibited by treatment with CNI-1493.CONCLUSIONS: p38 MAPK activation is one important aspect of the signaling events that may mediate the KCs production of pro-inflammatory cytokines, TNF-? and IL-1?, in SAP rats. The inhibition of the p38 MAPK may be a potential target in the prevention and treatment of SAP.

Objective To investigate the effects of modafinil,a new wake-promoting agent, on vestibular function during 24 h sleep deprivation(SD). Method Eight male healthy young volunteers were exposed to two 24 h periods of continuous wakefulness during the crossover experiment. In one period, 200 mg doses of modafinil were given and in the other, separated by one week, matching placebos were administered. The SD time started from 8:00 of the first day to 8:00 of the second day. Drugs was given at 0:00 of the second day. Vestibular function was tested at 21:00 of the first day and 1 ,3,5,7 h after drug administration. Result The accuracy of saccade tracking and the gains of VVOR(visual-vestibular optokinetic reflex)and OKN(optokinetic nystagmus)in the placebo group decreased during 24 h SD, especially at 1: 00~5:00 of the second day, while OKN gains in the modafinil group was increased significantly. There were no significant differences of other vestibular function between modafinil group and placebo group. Conclusion Twenty four SD can influence vestibular function in certain degree,but optokinetic nystagmus can be improved by modafinil.

Objective To explore the influence of tranSCription factor FOXC2 in angiogenesis of breast cancer MCF-7 cells and to clarify the action mechanism of FOXC2 in promoting tumor angiogenesis.Methods FOXC2 gene and empty vector gene were transfected into breast cancer of MCF-7 cell line with FOXC2 lentivirus gene transfection technique to obtain stable transfection cell line. The MCF-7 cells were devided into non-transfected group,empty-vector group and over-expression group.Matrigel assay and Transwell chamber test were used to observe the changes of tube formation and migration ability of human umbilical vein endothelial cells (HUVECs)in MCF-7 cells supernatant in various groups. PT-PCR and Western blotting methods were applied to detect the expressions of FOXC2,DLL4 and Notch1 mRNA and protein.Results Compared with non-tranfected group and empty-vector group,the tube formation and the migration number of HUVECs in FOXC2 over-expression group were increased(P<0.05);the expressions of FOXC2,DLL4 and Notch1 mRNA and proteins were significantly increased(P<0.05).Conclusion The FOXC2 over-expression in MCF-7 cells can increase the tube formation ability and migration ability of HUVECs,and its mechanism may be related to Notch signaling pathway.
