BACKGROUND: Oriental medicine is a part of medical service in Korea. However, there are no information about the status of infection control program in oriental medical hospitals. The purpose of this study was to investigate the current status of infection control activities in oriental medical hospitals and to provide a data to establish infection control policy in oriental medical hospitals. METHODS: This study was based on the survey questionnaires about infection control program and activities with total 13 oriental medical university hospitals in Korea. Questionnaires were collected from February 1 to March 31, 2011. RESULTS: Nine hospitals (69.2%) had infection control practitioner (ICP). Only 4 hospitals (30.8%) had full-time ICP and infection control office. The 6 hospitals (46.2%) had a position for infection control doctor and half of them were oriental medical doctors. Eight hospitals (61.5%) had an infection control committee and they had a meeting for average 2.5 times a year. Six hospitals (46.2%) performed surveillance and most of them were monitoring site directed infections. Only 4 hospitals have microbiology laboratory. All hospitals were using disposable acupuncture needles. Six hospitals were only using disposable wet cupping. Two hospitals (15.4%) were reusing wet cupping after disinfection. CONCLUSION: Through this study it was able to find out the status of infection control activities in oriental hospitals. There were also many limits on infection control activities in oriental medical hospitals. Based on this study it is needed to develop the infection control guideline and education for associates in oriental hospitals.

BACKGROUND:The cytokine has an effect of immunoregulation and immediate induction in the reconstruction of periodontal tissue. At present, the role and mechanism of hepatocyte growth factor involving the reconstruction of periodontal tissue under orthodontic force are stil unclear.
OBJECTIVE:To explore the mechanism underlying hepatocyte growth factor in the tooth movement and periodontal tissues remodeling under the inflammation periodontal tissue condition.
METHODS:Thirty Sprague-Dawley rats, aged 8 weeks, were used to establish periodontitis model. The obtained model was randomly divided into two groups:inflammatory control group and inflammatory force group. In the force group, rats were treated with the fixed orthodontic appliance by 50 g forces in the maxil ary first molars. After 1, 3, 5, 7 and 14 days of tooth movement, five rats were sacrificed respectively. Hematoxylin-eosin staining and immunohistochemistry methods were used to analyze the expression and distribution of hepatocyte growth factor in the periodontium for rats at different tooth movement stages.
RESULTS AND CONCLUSION:Hematoxylin-eosin staining results showed that, remodeling of periodontal tissues existed in al groups. (2) The immunohistochemical results showed that hepatocyte growth factor had positive expression in periodontal tissue, and the distribution was even in the control group. In the force group, hepatocyte growth factor expression was increased and reached the peak on day 5, then began to decline. Osteoblast, fibroblast and osteoclast were strongly expressed. The findings indicate that, hepatocyte growth factor is involved in the periodontal tissues remodeling under orthodontic force, and inflammation can increase the expression of hepatocyte growth factor in periodontal tissue.

Objectives: Use antisense VEGF to reduce the immunosuppression induced by tumor and enhance the antithumor effect of IL-2. Methods: After the MMT45.Li murine liver cancer cells were modified with antisense VEGF alone, or antisense VEGF combined with IL-2 gene, the tumorigenesis of modified MM45T.Li was studied. The apoptosis of cancer cell induced by antisense VEGF and IL-2 gene in vivo was also studied. The tumors were cryosmeared 3 weeks after the mice bearing tumor were treated correspondingly with Ad-antiVEGF or Ad-Il-2 or Ad-antiVEGF/IL-2 or Ad-lacZ, the immunohistochemical analysis of CD4 + , CD8 + was performed.Results: The tumorigenesis of MM45T. Li was reduced by antisense VEGF, and the number of CD4 + , CD8 + cell was increased in tumor tissue, and the immunosupression was also reduced; At the same time antisense VEGF also enhanced the antithumor effect of IL-2 gene.Conclusions: Antisense VEGF not only can inhibit the neovascularization, but also can reduce the immunosupression induced by tumor, and improve lymphocyte infiltration toward tumor site;when it was combined with Il-2,anti VEGF can enhance the antitumor effect greatly.

Objective To analyze a large number of Cumulative Paternity Index (CPI) data in Single-parentage identification with stochastic simulation method. Methods Using the software in Identifiler, PP18D, AGCU EX20, PP21, AGCU 21+1 system, 1 million groups of STR genotyping of parent-child were analyzed. The average rate of very low CPI (RVLCPI), the median of PI in every loci (MPI), and the average PI of 39 STR loci (PIsolo) were counted out. And calculation formula of the number of STR loci that need more testing (N) was derived. Results RVLCPI in Identiifler, PP18D, AGCU EX20, PP21, AGCU 21+1 system were 24.9%, 6.5%, 1.4%, 0.7%, 0.000 1%. On the premise of inclusion relations between every kits, the number of autosome STR loci is inversely proportional to RVLCPI. PIsolo was 1.843 2. There was a signiifcant positive correlation between MPI and PEduo (r=0.956, P<0.001). The formula of the number of STR loci that need more testing was N=?log1.843 2(10 000/P)?. Conclusion The result and the formula in this paper are effcient in single-parentage identiifcation.

Objective To discover the operating problems through analysis of the financial situations of the rehabilitation institutions. Methods According to the different regions and different levels of rehabilitation institutions, 416 representative institutions from 26 provinc-es, municipalities and autonomous regions were surveyed. Results 329 effective questionnaires were recalled. 57.75%institutions relied on the superior departments in charge of funding, 51.09%institutions were in breakeven state. They were lack of sustainable development pow-er, and the capital expenditure was mainly used for staff salaries and equipment purchase. Conclusion To solve the shortage of funds in the development of rehabilitation institutions, we should establish a long-term mechanism of internal and external compensation.

To improve and optimize marine antimicrobial peptide R-1 production by a newly isolated Brevibacillus laterosporus Lh-1, Plackett-Burman (PB) design and response surface methodology (RSM) using central composite design was adopted in culture conditions. MINITAB 15.0 was used for planning the experiments, data analysis, contour diagrams and response optimizations. In this study, PB design was undertaken to evaluate the effects of the fifteen factors. By the statistical regression analysis, the significant factors affecting the novel antimicrobial peptide R-1 in submerged fermentation by Br. laterosporus Lh-1 were determined as follows: glucose, peptone and CaCl2. Then a RSM was used to optimize the above critical internal factors, and the optical concentration of the variables were deter-mined as: 15.72 g/L glucose, 6.01 g/L peptone and 3.29 g/L CaCl2. The content of R-1 was increased from 82.15 kU/mL to 116.27 kU/mL.

Objective To find out whether Shanghai residents have mastered the knowledge related to iodine deficiency disorders (IDD),and how they choose different kind of salt.Methods Residents were selected by stratified random sampling from all 18 districts(counties) of Shanghai in 2010.Simple random sampling was used at the first level; random function was used at the second level to produce the last 4 numbers of a phone number.People who own the number were selected to be called.Results Totally 219 people completed the investigation.49.3％ (108/219) of the residents only selected iodized salt,and 25.6％(56/219) choose non-iodized salt; 6.8％ (15/219) selected both,and 18.3％ (40/219) don't care.About the reason of choosing iodized salt,25.9％ (28/108) thought it can prevent IDD,6.5％ (7/108) thought it's good to children's intelligence.About the reason of choosing non-iodized salt,35.7％ (20/56) thought they were not iodine deficiency,17.9％ (10/56) thought Shanghai was not an IDD epidemic region.Among the 126 people who had heard of iodine deficiency disorders,7.1％ (9/126) believed that iodine deficiency disorders can lead to varying degrees of mental impairment,65.1％ (82/126) thought it can lead to endemic goiter; 45.2％(57/126) thought eating iodized salt and 33.3％ (42/126) thought eating kelp and laver can prevent IDD.58％(127/219) had no idea of IDD and/or its hazards.Conclusions The resident's knowledge on iodine deficiency disorders is not satisfactory.We should make more effort in health education and help people to choose salt reasonably.
