It is important and difficult to establish the market competition mechanism in the health care re-form. Medical voucher system in Hong Kong and Macao can provide policy guidelines for Mainland China to promote institutional innovation, force public hospital reform and the rational allocation of medical and health resources. This paper introduced the origin and development of medical voucher system. Based on the description of the implementa-tion background, similarities and differences and effects of medical voucher system in Hong Kong and Macao, the pa-per found that medical voucher system could help encourage the demander to make more frequent use of medical serv-ices, improve their consciousness of prevention and health care and promote family doctor system. Through analyzing the applicability of medical voucher system in mainland China, the paper pointed out it was consistent with the reform orientation and could be served as a useful supplement to the health care system to improve medical insurance, medi-cal assisstance system as well as an effective measure to develop private medical institutions.

Objective To investigate the signal transduction pathway mechanisms of rats with liver fibrosis regulated by leptin and interfering effects of mistletoe alkali .Methods The hepatic fibrosis in rats model was established by injecting carbon tetrachloride .Forty-five SD rats were randomly divided into normal group ,model group and therapeutic group.All rats except rats in normal group were intraperitoneally injected with 40%carbon tetrachloride in peanut oil with a dose of 2.0 mL/100g according to the body weight twice a week for 8 weeks.Then, the therapeutic group was given mistletoe alkali (8g/(kg· d)) for 8 weeks via gastrogavage.Rats in normal and model group were served with distilled water at the same time.At the end of the 16th week, blood and tissue specimens were taken from all the rats .The influence of mistletoe alkali on liver morphology in liver fibrosis rat model was reviewed by HE and Masson staining .The effects of mistletoe alkali on the expression of Leptin and its receptor ( OB-Rb ) in HSC in fibrosis rat model were determined by immunohistochemistry (IH).The expression of JAK2, STAT3 and the activity of phospho -JAK2, phospho-STAT3 were detected by Western blotting analysis .Results The degree of fibrosis of the model group was more severe than the normal group and the treatment group , which suggested that mistletoe alkali can reverse liver fibrosis in rats . Immunohistochemical staining showed that mistletoe alkali reduced the hepatic expression of leptin and OB -Rb in rats with liver fibrosis in comparison with their expression in the model group .Compared with the normal group , the expression of JAK2 and STAT3 increased in the model group .However, the expression of JAK2 and STAT3 decreased in the medication groups compared with the model group .Conclusion Mistletoe alkali can effectively ameliorate liver fibrosis in rats possibly through inhibiting hepatic leptin and its receptor expressions , which through inhibiting hepatic leptin and its receptor expressions , thus inhibit the JAK2/STAT3 signaling pathway .

AlM: To evaluate the clinical effect of 200g/L protein-free calf blood extract eye gel for corneal epithelial defect.METHODS: One hundred and sixty - eight cases of corneal epithelial defect ( 58 cases with herpes simplex keratitis; 24 cases with chemical injury; 85 cases with pterygium operation injury ) were randomly divided into two groups: 84 eyes were treated with protein-free calf blood extract eye gel; 84 cases were treated with basic fibroblast growth factor eye gel ( bFGF ) . The bFGF and protein-free calf blood extract eye gels were used 4 times a day. The treatment course was 7d. Epithelial defect restoration, local symptom and sign were observed.
RESULTS: The difference between pre-treatment and post-treatment was significant ( P<0. 01 ) in the two groups. The effect of protein-free calf blood extract eye gel (83. 3%) group was prior to that of bFGF (69%) for corneal epithelial defect. The effective rate of protein-free calf blood extract eye gel in the herpes simplex keratitis, chemical injury and pterygium operation injury was 72. 4%,69. 2% and 95. 2%. Localized stimulus and adverse reaction of all over the body were not been observed.
CONCLUSlON: Protein-free calf blood extract eye gels is valuable and safe for corneal epithelial defect.

Objective To explore the possible mechanism of action of telomerase in hepatic precancerous lesions, and the regulatory effect of a Chinese medicine prescription HU Qi Shan ( HQS) and its principal drug mistletoe alkali on the telomerase activity in rat liver tissues.Methods Rat model of hepatic precancerous lesions was established by Solt-Farber two-step protocol.The model rats were randomly divided into 5 groups, including the model group, high-dose HQS [8 g/(kg· d)] group, low-dose HQS [4 g/(kg· d)] group, and mistletoe alkali[8 mg/(kg· d)] group.γ-Glutamy-transpeptidase (γ-GT) was analyzed by immunohistochemistry.AFP was detected by immunofluorescence technique.The telomerase activity was detected using a quantitative telomerase detection kit.The expression of NF-κB P65 was detected by immunohistochemistry.The cytoplasmic protein IκB-αwas detected by western blotting.Results After treated with HQS and mistletoe alkali, the areas ofγ-GT-positive foci and number of AFP-positive cells in the liver tissus were significantly decreased than those of the model group ( P<0.05 for both) , the telomerase activity was decreased, the number of NF-κB P65-positive cells was also decreased ( P <0.05 ) , whereas the intracytoplasmic expression of IκB-αproteins was significantly increased ( P <0.05 ) .Conclusions HQS and mistletoe alkali can suppress the telomerase activity.Its possible mechanism may be through inhibition of the over-expressed apoptosis-related genes such as NF-κB P65 and increase the expression of IκB-αdecreasing the telomerase activity.

Objective To measure the level of interleukin (IL)-27 in sera of patients with Sj(o)gren's syndrome (SS) and investigate its role in IL-10 in CD3+CD8-T cells.Methods Serum levels of 1L-27 and IL-10 from 34 SS patients and 33 healthy controls were tested by enzyme linked immunosorbent assay (ELISA).Peripheral blood monocytes (PBMCs) from SS patients were collected and cultured in different conditions (one with PHA,the other with PHA and IL-27).Seventy-two hours later,cells were harvested and the percentages of CD3 +CD8-IL-10+ cells were measured by flow cytometry.Expressions of c-Maf,IL-10 transcription factor,were examined using real-time polymerase chain reaction (PCR).The data were analyzed by t test,Pearson's correlation analysis and multiple linear regression analysis.Results Serum level of IL-27 in patients with SS [(158±34) pg/ml] was significantly higher than that in healthy controls [(139±18) pg/ml,t=2.823,P＜0.01].IL-27 level was positively correlated with IL-10 and IgG levels (r=0.384,P＜0.05; r=0.354,P＜0.05),but negatively correlated with SSDAI (r=0.503,P＜0.01).Multiple regression analysis showed independent correlation of IL-27 with IL-10 and SSDAI in SS patients (β=0.412,P＜0.01; β=-0.525,P＜0.01),but not IgG.CD3+CD8-IL-10+ cells was upregulated by IL-27 in vitro (P＜0.01,n=14),so was c-Maf (P＜0.01,n=22).Conclusion IL-27 could ameliorate disease activity of Sjogren's syndrome.

Objective To investigate the clinical application and manifestation of dynamic contrastenhanced MRI (DCE-MRI) in differentiating true progession from pseudoprogression in patients with gliobastomas.Methods Twenty five glioma patients were treated with postoperative concurrent chemoradiotherapy and enrolled in this study.All patients were underwent DCE-MRI using a 1.5T scanner.Fifteen patients were confimmed by secondary pathology or clinical and imaging follow-up of patients with gliomas true progession (TP),10 patients were pseudoprogress (PP).Nonparametric Mann-Whitney test was used to compare perfusion parameters between two groups (TP and PP),were used for receiver operating characteristic (ROC) curve analysis to clear if these parameters can be the indicators to differentiate true progession from pseudoprogression.Results Ktrans (volume transfer constant),Ve (fractional volume of extravascular extracellular) values between TP and PP glioma groups were statistically significant,K and Ve values were significantly higher in the TP group than in the PP group (P ＜ 0.05).The areas under the ROC curve are 0.990 and 0.847,respectively.Kep (efflux rate constant) value,Vp (fractional volume of plasma) value in the identification of glioma TP group and PP group was not statistically significant (P ＞ 0.05).Conclusions DCE-MRI can be used to identify glioma TP and PP,Ktrans value and Ve value have clinical significance.

Objective To evaluate the early emergency management process for severe pelvic fractures combined with multiple trauma. Methods The study involved 113 patients with severe pelvic fractures combined with multiple trauma treated from January 2007 to May 2011.The patients were divided into two groups,ie,before trauma team establishment (26 patients treated from January 2007 to May 2008) and after trauma team establishment (87 patients treated from June 2008 to May 2011 ) in accordance with the establishment period of trauma team in June 2008.The mortality was compared before and after application of trauma-team-based algorithm with damage control resuscitation,external fixation and angiographic embolization.Variables including age and gender distribution,ISS score,injury type and mechanism,transportation time,associated injury number,initial systolic pressure hemoglobin and blood transfusion were analyzed for study of their relation with mortality. Results After trauma team establishment,the mortality (23％) was significantly lower than before trauma team establishment (46％).The mortality showed significant relation to ISSN score and over two regions of associated injury,but showed no correlation with age and gender distribution,injury type and mechanism,transportation time initial systolic pressure hemoglobin,and blood transfusion. Conclusion The application of trauma team is effective in treatment of severe pelvic fractures combined with multiple trauma and can decrease the mortality.
