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.

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.

To observe the curative effect of treating small -incision cataract extraction by intraocular lens implantation combined with trabeculectomy for primary angle-closure glaucoma with cataract.
●METHODS: Totally 44 cases (52 eyes) of primary angle-closure glaucoma combined with cataract were selected to undergo the combined surgery, in order to observe the patients' pre - and postoperative eyesights, intraocular pressures and the postoperative complications.
●RESULTS: The postoperative eyesight was improved significantly as compared with the preoperative eyesight. The intraocular pressure was declined dramatically. The result was of statistical significance (P<0. 05). All the 52 cases' surgeries were performed by the same surgeon. The surgeries were processed smoothly, with 6 postoperative eyes of anterior chamber inflammation cell response, 3 eyes of anterior chamber fibrinoid exudate, 2 eyes of shallow anterior chamber through mydriasis and treatment with glucocorticoids and non - steroidal eyedrops before absorption, and no complications like malignant glaucoma, cyclodialysis, etc. were reported through mydriasis and pressure bandaging before recovery.
● CONCLUSlON: Treating the primary angle - closure glaucoma combined with cataract through the combined surgery has high reliability and desirable curative effect. The surgical method is simple to learn and applicable for promotion on the basic level.

Objective To investigate the clinical, electrophysiological and pathological features of critical illness polyneuropathy and myopathy (CIPNM). Methods The clinical outcomes, electromyogram Results as well as pathological features in nerves and muscles of 3 patients with CIPNM were investigated and analyzed. Results 3 patients were all provided with assisted respiration after tracheal intubation. 7～10 d after intubation, all the patients emerged muscle strength and tendon reflexes of extremities weakening; while 14 days after that, 2 patients appeared amyotrophy of extremities. Electromyogram showed that the conduction of many motor and sensory nerves for extremities decreased, while the amplitude of compound muscle action potential (CMAP) of part of motor nerves decreased. Biopsy for nerves revealed decreased medullated nerve fibers and regeneration phenomenon of auxiliary fibers; while that for muscles showed neuralgic damage and myopathy-like changes. Conclusion CIPNM can complicate after tracheal intubation. The electrophysiological and pathological examinations for nerves and muscles can be helpful for the diagnosis.

Background and purpose:LMP1 was one of the protein encoded by EBV latent gene,which was found to be able to transform cell lines and alter the phenotype of cells due to its oncogenic potential.In human epithelial cells,LMP1 alters many functional properties that are involved in tumor progression and invasions.In this study we investigated the influence of LMP1 silence on AP-1 signal transduction pathway and its downstream factors involved with cell transformation,proliferation and apoptosis.Methods:The chemically synthetic siRNA targeting LMP1 was transfected into EBV positive gastric carcinoma epithelial cell line by lipofectamine 2000 at 50 nmol/L final concentration.The protein expression of c-Jun,JunB and CDK4 was tested by,Western blotting.The mRNA of c-Jun,surviving,CDK4 and MMP9 mRNA were tested by RT-PCR.The expression of survivin were tested by immunohistochemistry.Results:Compared with the cell control,CDK4 mRNA was up regulated(P

Objective To determine whether arsenic has estrogen-like effects,the cell proliferation was measured iil human eervical cancer line(HeLa)in vitro.Methods The HeLa cells were grown in improved RPMI 1640 supplemented respectively with β-estradiol(E2,1 nmol/L),Arsenic trioxide(As2O3,0.5,1.0,5.0 μmol/L),ICI (500 nmol/L),E2(1 nmol/L)+ICI(500 nmol/L),As2O3(1.0 μmol/L)+ICI(500 nmol/L)and control.The growth morphology of HeLa cell was observed under microscope after 72 h.The method of M1Tr was used to study the cell proliferation after 24.48 and 72 h.The technique of flow eytometry was used to measure cell cycle after 48 h. Results HeLa cells in E2 and 0.5 μmoL/L As2O3 treatment were more better growth in morphology than control group.Percentage of HeLa cells proliferation at 24,48,72 h in E2 and 0.5 μmol/L As2O3 treatment were 6.35%, 11.56%,38.33%and 6.35%,8.50%,20.26%respectively.The proliferation effect of HeLa cells was similar in two treatments.The proliferation of HeLa cells were inhibited in other treatments.Compared with control[(41.68± 1.05)%],HeLa cells were promoted go to S phases in E2[(55.72±2.31)%]and 0.5 μmol/L As2O3[(47.82± 1.41)%]treatment.But in other treatments HeLa cells were hold back to S phases.Compared with control,there was a significant differenee(P＜0.05)of cell percentage in S phases in 5.0 μmol/L As2O3[(21.11±4.99)%]and ICI[(20.16±4.76)%]treatments.Conclusion Small amounts of As2O3 impose estrogen.1ike effects and stimulate the proliferation of HeLa cells.

Objective To investigate the prevalence of clonorchiasis among residents of Huachuan Country,Heilongjiang Province and to provide a basis for development of control strategies.Methods From 2011 to 2012,cluster random sampling was performed to survey the incidence of clonorchiasis in Huachuan Country.Fecal specimens were collected and examined the clonorchis sinensis eggs by Kato-Katz method.A questionnaire survey was conducted to collect related information such as age,gender,occupation and eating habits.The infection characteristic was analyzed.Results Totally 884 patients with clonorchiasis were found among 2248 residents,and the infection rate was 39.32％.The infection rate in male[47.15％(611/1296)] was significantly higher than females [28.68％(273/952),x2 =34.55,P ＜ 0.01].The infection rate increased with age,which was higher in the 20-69 years old people,with the highest infection rate in the 50-59 years old groups[45.34％ (219/483)].Of the occupational distribution,farmers had the highest infection rate [47.24％ (420/889)],followed by cadres and staffs[38.38％(190/495)].Of residents with fresh fish eating history,the prevalence of clonorchiasis was 53.38％(150/281).Conclusions The prevalence of clonorchiasis is still high in Huachuan County.To reduce the prevalence of clonorchiasis,comprehensive prevention measures,health education and group chemotherapy should be carried out.
