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.

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.

Objective To analyze the clinical and laboratory characteristics of the ischemic stroke in patients with non-valvular atrial fibrillation (AF), and to provide evidence for the prevention of ischemic stroke. Methods A total of 198 patients with ischemic stroke were chosen and divided into two groups:with AF (71 patients)/and without AF (127 patients) groups. Clinical data and biochemical markers were collected and compared in two groups. CHADS2 and CHA2DS2-VASc score systems were used to determine the risk levels in patients with AF. Finally, related risk factors of ischemic stroke with AF were determined and analyzed. Results The values of age, length of hospital stay, the hypertention history, heart rate and plasma homocysteine (Hcy) were significantly higher in the with-AF group than those in the without-AF group ( P <0.05). The levels of total cholesterol (TC), triglyceride (TG) and very low density lipoprotein cholesterol (VLDL-C) were sig?nificantly lower in the with-AF group than those of the without-AF group (P<0.05). CHA2DS2-VASc scores reached to the moderate-to-high risk level in the with-AF group. Multiple-factor logistic regression analysis showed that age and heart rate were the independent risk factors of the ischemic stroke in patients with non-valvular AF. ROC analysis indicated that age (AUC=0.761, cut-off point=72.50 years old) and heart rate (AUC=0.612, cut-off point=76.50 bit/min) had predictive and di?agnostic value for the ischemic stroke in patients with non-valvular AF. The age of these patients had the best sensitivity (70.4%) and specifity (71.1%), and the cut-off point of which was 72.50 years old. Conclusion The characteristics of isch?emic stroke in patients with non-valvular AF includes older age, faster heart rate, higher CHA2DS2-VASc scores and higher Hcy level.

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.
