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.

Medical genetics is one of the important basic courses in medical education. The teaching reform in course content, teaching method and experimental teaching was carried out to arouse their enthusiasm in study, cultivate their capabilities of analyzing of medical practice problem.

With the advent of intellectual economy and information,the progression of rule of law,and the reforming of system of forensic science in China,some aspects of the higher education of forensic medicine are faced with unprecedented chance and challenge and have to be improved in order to adapt to training creative talented person of forensic medicine in our society.The aspects to be improved include the system of student enrollment,the pattern of higher educa-tion and training of forensic doctor,the contents of forensic medicine course,the traditional teaching method of forensic medicine,and the graduates'further education 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 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.

Objective To find out the status of prevention and control of iodine deficiency disorders and evaluate the iodine nutritional status of Jinan residents,to explore appropriate iodine level in drinking water,and to provide a scientific basis for adjustment of intervention strategies.MethodsAccording to the Monitoring Program of the National Iodine Deficiency Disorders (Trial),qualified iodized salt consumption rate,drinking water iodine content and urinary iodine levels of women of childbearing age were determined in iodine deficiency areas from 2003 to 2010.Salt iodine was detected by direct titrimetry,urinary iodine by As-Ce catalytic spectrophotometric assay and iodine in drinking water by cerous sulfate catalytic spectrophotometric method.Results Intake rate of qualified iodized salt was up to 90％ and above from 2003 to 2010,median water iodine was 13.65 μg/L in the 10 counties(cities,districts),of which less than 100 μg/L accounted for 79.82％(4560/5713 ) and ＞ 150 μg/L accounted for 12.73％(727/5713).With the increase of water iodine(0 ～ ＜ 10,10 ～ ＜ 50,50 ～ ＜ 100,100 ～ ＜ 150,150 ～ ＜ 300 and ≥300 μg/L),urinary iodine levels of women of childbearing age increased successively(median 156.56,175.81,267.04,349.00,524.22,583.20 μg/L,respectively,x2 =121.20,P ＜ 0.05),while the ratio of urinary iodine ＜ 100 μg/L was significantly lower.The ratio of urinary iodine between 100 and 300 μg/L was decreased gradually,but the ratio of great than 300 μg/L was gradually increased.ConclusionsIodine deficiency areas in Jinan have reached the standard of elimination of iodine deficiency disorders.We should insist to carry out our measures to suit local conditions,classified guidances and scientific principals of iodine supplementation.

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.
