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 According to the data collected from gastric cancer families comparative study, the influence factors of Hardy-Weinberg (H-W) equilibrium in the association studies of gene polymorphism and disease were analyzed to reveal the reasons that affecting the equilibrium deviation in the group. Methods Varieties of risk genotype for gastric cancer were analyzed and detected with H-W equilibrium, genetic linkage disequilibrium analysis and Cochran-Armitage trend test. Results (1) Significant deviations from H-W equilibrium were observed in IL-1B-31, IL-IB-511, IL-IRN and TNF-A-308 of the cases and controls (P<0.01). MIF-173 tended to be equilibrium in the population. (2)Deviations from expectations of phenotypes combination probability were observed in two-site H-W χ2 tests (P< 0.01). (3)The Cochran-Armitage trend test showed that distribution of IL-1B-511 and IL-1RN were significantly different(P<0.05), suggesting that population stratification might have existed in the group. Conclusions (1)Affected by frequency-dependent selection, under the combination of linkage disequilibrium, mutations and interaction, genotype frequency of IL-1B-31, IL-1B-511, IL-1RN and TNF-A-308 showed deviation from H-W equilibrium in population. (2)Two-site genetic equilibrium test model seemed better to reflect the differences of phenotypic combination fitness. (3)Population stratification was another factor to express the deviation from H-W equilibrium.

Objective To explore the diagnostic values of X-ray and CT examinations for the traumatic diaphragmatic rupture. Methods Totally 17 patients with traumatic diaphragmatic rupture were retrospectively analyzed, who underwent X-ray chest radiograph and 64-slice spiral CT examinations as well as coronal and sagittal imaging by multi-planar reconstruction with GE ADW 4.6 workstation. Results Of the 17 patients, there were 15 ones had the rupture occurred on the left side (93.7%), one case on the right side (6.3%) and the remained one had no diaphragmatic injury;there were 10 ones of diaphragmatic contour discontinuity, 6 ones of intrathoracic hernia, 2 ones of cervical stenosis, one case of hanging sign and two cases of falling viscera sign. Conclusion Routine chest X-ray radiography has difficulty in diagnosing diaphragmatic rupture, while CT multiplanar imaging contributes to determining traumatic diaphragmatic rupture. Diaphragmatic rupture may occur after multiple trauma, and CT with multiplanar reformations has to be used as the routine examination for diagnosing diaphragmatic rupture.
