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.

With the rapid development of healthcare technologies, the improvement of patient health expecta-tions, and the increasing of the government or insurer's financial budget pressure, risk-sharing agreements has be-come the focus of the governments or insurer concerned. This article systematically analyzed Australia, New Zealand, Taiwan risk-sharing agreements from five aspects, including the operation main, scope, classification, application processes and the implementation effects. According to the results of the analysis, we suggests that China should im-prove risk-sharing agreements theoretical basis, diversify risk-sharing agreements models, establish risk-sharing a-greements standardization process and so on.

OBJECTIVETo investigate the resistant effect of houttuyfonate sodium (SH) combined with imipenem (IMP) against Pseudomonas aeruginosa (Pa) biofilms.
METHODThe two-fold dilution method was used to examine the minimum inhibitory concentration (MIC) of the tested drug. The crystal violet staining was applied to detect the effect of the combination of 1/2MIC, 1MIC, 2MIC of SH, single IMP, 1/2MIC of SH and IMP of various concentrations on the clearance rate of adherent bacteria, growth of biofilms and alginate production. Fluorescein diacetate (FDA)-propidium iodide (PI) doubling staining assay was employed to observe the bacterial viability and morphological changes after membrane dispersion of each drug group.
RESULTSodium houttuyfonate could enhance the effect of IMP against pseudomonas aeruginosa biofilms. Particularly, the combination group with the concentration of 2MIC showed the highest effect, with P < 0.001 compared with the negative control group. The above results were proved by the bacterial viability and biofilm morphology under fluorescence microscope.
CONCLUSIONAfter being combined with imipenem, sodium houttuyfonate shows a higher effect against biofilms. It is expected that the combination of the two drugs could improve the clinical efficacy of associated infections.

Objective To assess the effects of fenofibrate on myocardial remodeling in obese rats by echocardiography.Methods Twenty-six SD rats were fed with high fat chow to establish twenty obese rats models,which were randomly divided into two groups:obesity group (OB group,n =10) and fenofibrate group(F group,n =10).The same week-old SD rats group (n =10) was also randomly selected as normal control group.F group was given fenofibrate 60 mg · kg-1 · d-1 for 8 weeks,the other groups were given normal saline.Echocardiographic scan was performed in each group at the beginning and ending of the experiment.Twenty-four weeks later,all rats were executed and the cardiac muscle was used to histological inspect.Results After the experiment,compared with the control group,the body weight,the ventricular thickness,interventricular septal thickness and the left ventricular mass in OB group were significantly increased than those of control group(P <0.01),the E/A ratio was significantly decreased(P <0.01).Histological detection showed that myocardial structure was disordered,and that interstitial collagen was deposited in the myocardium.Compared with OB group,the parameters all above in F group were significantly improved (P <0.01).Left ventricular mass from echocardiography correlated well with the results from pathologic specimen (r =0.98,P <0.01).Conclusions Fenofibrate has beneficial effects on preventing myocardial remodeling.By general echocardiography,the effects can be assessed comprehensively and accurately.

OBJECTIVE To investigate the incidence and pathogens of infection in 1659 consecutive cases in single center hematological unit.METHODS The incidence,pathogen,and outcome of infection in 1659 hospitalized patients with hematological disorders from 1999 to 2006 were retrospectively analyzed.RESULTS The overall incidence of infection was 24.4% according to the person-times of hospitalization,which included 22.1% of nosocomial infection and 2.3% of community acquired infection.Most of the pathogenic bacteria of the nosocomial infection were Gram-negative.The most common bacteria in the sputum samples included Enterobacter cloacae(19.3%) and Pseudomonas aeruginosa(14.8%).The most common bacteria in the blood samples were coagulase negative Staphylococcus(CNS,39.3%),the next was Pseudomonas aeruginosa and Escherichia coli.There were 4.21% bacteria resistant to most of antibiotics in nosocomial infection.There were 114 fungi isolated.Candida albicans was accounted for 35.1%.The mortality due to nosocomial infection was 7.4%.CONCLUSIONS The patients in hematology ward are susceptible to infection.The pathogens of nosocomial infection are most likely G-bacteria.Some bacteria are resistant to almost all antibiotics.The incidence of fungal infection is increasing in the near 8 years.

BACKGROUND:Stroke is the leading cause of death and long-term disability. This study was undertaken to investigate the factors influencing daily activities of patients with cerebral infarction so as to take interventional measures earlier to improve their daily activities. METHODS:A total of 149 patients with first-episode cerebral infarction were recruited into this prospective study. They were admitted to the Encephalopathy Center, Department of Neurology, the First Affiliated Hospital of Wenzhou Medical College in Zhejiang Province from August 2008 to December 2008. The baseline characteristics of the patients and cerebral infarction risk factors on the first day of admission were recorded. White blood cell (WBC) count, plasma glucose (PG), and many others of laboratory targets were col ected in the next morning. Barthel index (BI) was calculated at 2 weeks and 3 months respectively after onset of the disease at the outpatient clinic or by telephone cal . Lung infection, urinary tract infection and atrial fibrillation if any were recorded on admission. The National Institute of Health Stroke Scale (NIHSS) scores and the GCS scores were recorded within 24 hours on and after admission, at the second week, and at the third month after the onset of cerebral infarction respectively. RESULTS:The factors of BI at 2 weeks and 3 months after onset were the initial PG level, WBC count and initial NIHSS scores. Besides, urinary tract infection on admission was also the factor for BI at 3 months. CONCLUSION:Active measures should be taken to control these factors to improve the daily activities of patients with cerebral infarction.
