Objective:To forecast Urban Employees' Basic Medical Insurance ( UEBMI) in the next 85 years based on population size, age and gender distribution, and to calculate its sustainability gap. Methods:According to the population policy of Beijing and economic development of the region;based on the data of the sixth census in Bei-jing, the estimation model was constructed, and its parameters were defined and selected. Based on the period of 2010, the future of UEBMI in the next 85 year was predicted based on the population size, age and gender distribu-tion. Results:The population of UEBMI in Beijing will reach the maximum value in 2020, and then the downward trend will increase. The aging rate of the insured population will accelerate year after year and will reach the peak in the middle of this 21st century. The sustainability gap is predicted to reach at least 9541. 35 Billion dollars, and the Beijing municipal government is expected to level an average of at least 44 . 693 billion yuan per year to set aside the financial funds in order to fill the gap, so sustainable development of the fund is ensured. Conclusion:From the point of view of the insured population, there is a huge financial sustainability risk in the future of UEBMI in Beijing.

Objective To construct the vector pcDNA3.1 containing VEGF165 gene and examine of pcDNA3.1-VEGF165 vector to the angiopoiesis, composition of collagen in rabbit bone defect model. Methods Extract total RNA from the rabbit tissue. Prepare cDNA by inverse transcription and clone the gene by PCR. Clone plasmid pMD18-T/VEGF165 combined with pcDNA3.1 to reconstruct pcDNA3.1- VEGF165. 28 New Zealand white rabbits weighted (2.0?0.130) kg were made bone defect model for 10 mm length in the bilateral radii. Cut down the skin, resect the bone of 10 mm in length in the middle of radius. The pcDNA3.1-VEGF165 0.2 ml (200 ng) plasmid was injected at one defect side randomly. The defect in the other side was served as control group, and injected with absorbable gelatin sponge and sodium chloride 0.2 ml. After the examination by X-ray the local specimens were obtained at 1,2,4,6,8,and 12 weeks respectively. The expression of collagen type Ⅰ and Ⅲ was examined at 4, 12 weeks by immunohistochemical staining techniques. Results The pcDNA3.1-VEGF165 vector was constructed successfully. The roentgenography: there was no difference between the two sides after 1 week operation; 2 weeks after the operation, there were some callus in the experimental group; there was nothing in the control group. After 4 weeks, there were much callus, synostosis and others in the experimental group, all of these were late in the control group. Two groups were healed after 12 weeks, the bone density was lower in the control group. Inflammatory cell infiltrate, cellular interstitialis, fibroblast, collagen and osteoblast were no difference between the two groups only at the first week, but the density of angiogenesis was much more in the experimental group at the following times. Expression of collagen type Ⅰ, Ⅲ were more intensity in the experimental group than the control one at 4,12 weeks. Conclusion Transcription to local bone cells at defect position with pcDNA3.1-VEGF165 plasmid can enhance quantity of the angiopoiesis, extra cellular matrix and the healing of bone defect.

Objective To investigate the early comprehensive intervention on neonatal hypoxic ischemic encephalopathy (HIE) effects and the biological mechanisms.Methods 120 cases of HIE were randomly divided into intervention group and control group.Under the basis of drug treatment,the intervention group were given the different perceptual stimuli,audiovisual stimulation,active and passive limb training early comprehensive intervention,the control group only to normal drug treatment.The mental development index(MDI) and psychomotor develo pmental index (PDI) were applied after 3,6,12,and 18 months.S100B protein levels were detected using enzyme immunoassay.Results MDI score in the intervention group with HIE,from the beginning of the 12 month,was higher than that in the control group,there was significant differences (12th month:(96.6±9.4)vs (86.8±9.5),P<0.01).PDI score from the beginning of the 6 month,was higher in the intervention group with HIE than that in the control group,there were significant differences (6th month:(91.6±9.2)vs (82.2±11.0),P<0.01).Serum S100B protein level has a tendency to fall for all HIE patients with the old growth.Born in two groups of serum S100B protein levels were higher in neonate period,but there was no difference(P>0.05).From the beginning of the 3rd month,serum S100B protein levels in the intervention group were reduced significandy,compared with the control group at each time point level(3rd month:(1.29±0.15)ng/L vs(1.40±0.14)ns/L;6th month:(1.06±0.21)ng/L vs(1.26±0.22)ng/L,P<0.01).Conclusion Early intervention can improve the mental and motor development of children with HIE,and serum S100B protein is involved in the mechanisms.

Objective To assess the human β-defensin-2 ( hBD2 ) gene therapeutic efficacy in a rat urinary tract infection (UTI) model via intravesical liposome-mediated gene transfer.Methods Fifty-six female Wistar rats (class SPF) weighting 1 80 -220 were randomly divided into an experiment group and a control group ( each n =28 ).The animals were administered either 250 μl recombinant pCAGG-hBD2 or control vector pCAGG intravesically.After 48 h,rats in both groups were infected via intravesical inoculation with 200 μl of the bacterial suspension of UTI89 ( 1 × 108 CFU/ml).The rats were sacrificed at 4,24,48,and 72 h post-inoculation.The bladders were aseptically removed and bisected.One half was fixed in neutral buffered formalin for histological analysis.The remaining half-bladders were homogenized and titered for surviving bacteria.The clean-catch urine sample from each rat was collected in sterile before they were killed for bacterial titers determined and WBC counted.Results Numbers of bacterial colony-forming unit in urine and bladders from hBD2 gene treated UTI rats were significantly lower than those from the control vector administered UTI rats at 24,36,and 72 h after infection ( P ＜ 0.05 ).The amount of WBC in urine was significantly less in the defensin group than in the control group.In addition,in vivo expression of hBD2 could reduce mucosa damage,interstitium edema and inflammatory cells infiltration in UTI animals.Conclusions The successful inhibition of UTI progression could be obtained with hBD2 gene therapy.Recombinant beta-defensin-2 could kill UTI89 in vivo and suppress the subsequent infection-induced inflammatory responses.

BACKGROUND: Hydroxyapatite has favorable biocompatibility, can protect pulp tissue and promote the formation of osteoid dentin and the concrescence of pulp tissue. However, hydroxyapatite has no capability of anti-infection. Increasing scholars deem that antibacterials should be added with the hydroxyapatite during the treatment of vital pulp conservation to elevate curative effects.OBJECTIVE: To observe the curative effects of self-solidifying hydroxyapatite/norvancomycin composite as pulp capping material and to make a comparison with calcium hydroxide.DESIGN, TIME AND SETTING: The present randomized controlled observation experiment was performed at the General Dental Clinic, the Ninth People's Hospital, Shanghai Jiao Tong University Medical College between January 2004 and June 2005.PARTICIPANTS AND MATERIALS: A total of 60 patients (60 teeth) that suffered from deep caries or pulp exposure, could return visit on time, and agreed to sign informed consents were selected for this study. These patients comprised of 28 males and 32 females, aged 9-40 years. Diagnosis criteria: Teeth with food impaction pain and/or caloric stimulation pain which can relieve after stimulation removal; in addition, with no spontaneous pain, radiating pain, and hypnalgia. Self-solidifying hydroxyapatite/2.5% norvancomycin composite were prepared in the Department of Dental Material, Shanghai Second Hospital. Self-hardening calcium hydroxide was provided by Dentsply Company, USA.METHODS: All 60 patients were randomly divided into an experimental group and a control group, with 30 patients (30 teeth) per group. Self-solidifying hydroxyapatite/2.5% norvancomycin composite and self-hardening calcium hydroxide were applied as pulp capping agents in the experimental and control groups, respectively. Pulpal tissue reactions were assessed after 8 weeks. Teeth with normal response were restored permanently, and the others were given root canal treatment.MAIN OUTCOME MEASURES: Pulpal tissue reaction of patients.RESULTS: In the experimental group, one case showed vague pain after 1-week pulp capping and received root canal therapy, with success rate of 97%. In the control group, two cases presented with vague pain after 3-day and 1-week pulp capping, respectively, and also received root canal therapy, with success rate of 93%.CONCLUSION: Self-solidifying hydroxyapatite/norvancomycin composite acquires a high success rate of pulp capping, with curative effects similar to calcium hydroxide, it is a good pulp capping agent for vital pulp preservation.
