Brother of regulator of imprinted sites (BORIS), also known as CCCTC binding factor-like (CTCFL), is a relatively newly discovered cancer-testis antigen. Drug development related to BORIS has been carried out in multiple directions, including small molecules, small RNA molecules, polypeptides, vaccines, and cellular therapies. Due to its unique ability to interfere with the higher-order spatial structure of the genome, BORIS may represent a new class of drug targets. Here we systematically review the molecular biology research results related to BORIS, including the diversity of its gene products, the multipartite interactions mediated by BORIS, the subsequent impact on signaling pathways, and current drug development strategies, in order to gain a better understanding of the molecular mechanisms of BORIS in both upstream and downstream regulation networks and to identify potential research directions for further breakthroughs.

OBJECTIVE: To evaluate the curative effect and costs of sequential therapy with cefuroxime for lower respiratory bacterial infection.METHODS: A total of 180 patients with lower respiratory bacterial infection were randomly divided into 3 groups: persistent intravenous drip group,sequential therapy group,and per os group.The therapeutic effects and the adverse drug reactions of the three groups were observed,and the data were subjected to cost-effective analysis in pharmacoeconomics.RESULTS: In persistent intravenous drip group,sequential therapy group,and per os group,the costs were(1 673.00?183.85),(1 268.10?112.25) and(994.80?102.65) yuan,respectively, the clinical effective rates were 93.33%,89.66%,and 69.35%,respectively,the cost-effectiveness were 1 792.56?196.97,1 414.34?125.20,and 1 434.46?109.79,respectively,and the incremental cost-effective ratios were in the intravenous drip group and sequential therapy group were 2 828.19?338.62 and 1 345.64?47.27,respectively as against per os group.CONCLUSION: Among the schemes,sequential therapy is the optimal one.

Aim To investigate the effect of procyanidins on apoptosis in brain of experimental rats with intracerebral hemorrhage(ICH) and its possible mechanisms.Method Rat intracerebral hemorrhage model was established by injecting collagenase into the brain caudate nucleus.Fifty-four health Sprague-Dawley rats were divided into six groups randomly: sham operation group,model group of intracerebral hemorrhage,treatment groups with procyanidins at doses of 50 mg?kg~-1,100 mg?kg~-1 and 200 mg?kg~-1,and positive control group with nimodipine at dose of 10 mg?kg~-1.Twentyfour hours after operation,the content of glutathione(GSH) and activity of catalase(CAT) were measured.The levels of bax and bcl-2 were detected by method of immunohistochemistry,and the apoptosis in brain tissues was detected by method of TUNEL.Result In procyanidins groups(50,100 and 200 mg?kg~-1),the content of GSH and the activity of CAT were significantly higher than those in ICH group(P

In China, fall ranks the top 3 among adverse events in hospital and it is the first cause of death in the elderly aged 65 and above. Fall risk factors and characteristics, nursing assessment and nursing care interventions are reviewed in this paper to explore risk factors and further improve the nursing care interventions for falls in hospitalized elderly patients.

Objective To investigate the effects of β-arrestin1 on proliferation,migration,invasion and apoptosis of human gastric cancer BGC-823 cell line.Methods The expression of β-arrestin1 in human gastric epithelial cell line GES,human gastric cancer cell line BGC-823,MKN-28 and SGC-7901 was detected by realtime-polymerase chain reaction (PCR) and Western blot.The stable β- arrestin1 and negative control interfered BGC-823 cell line were established by RNA interference technology.The cell proliferation,migration,invasion and cell apoptosis of β-arrestin1 stable interfered BGC-823 cell line was examined by cell counting,scratch test,Transwell chamber test and flow cytometry assays.The data were analyzed by t test.Results The expression of β-arrestin1 in cell line GES,MKN-28,SGC-7901 and BGC-823 was 0.001 ± 0.001,0.002 ± 0.000,0.003± 0.002 and 0.005 ± 0.000 respectively.The inhibition ratio of proliferation in β-arrestin1 interfered BGC-823 cells and negative control cells were -30.2 ％ and 100.0 ％.The invasion ability was also inhibited,the number of migratory cells was 126.25±3.24 and 213.50±6.27 (t=0.000,P＜0.01),and the apoptosis rate was (41.350±1.053)％ and (11.497±0.589) ％ (t=0.015,P＜0.05).Conclusions β-arrestin1 is highly expressed in gastric carcinoma,and the expression increased along with the malignancy degree.The cell proliferation,migration and invasion is inhibited by interference of β-arrestin1 in BGC-823 cells,while the cell apoptosis is promoted.

Objective:To study the antihyperglycemic effect of water soluble polysaccharides (MCW) and alkaline soluble polysaccharides (MCB) from Momordica charantia L. on streptozotocin-induced diabetic mice. Method:Twelve mice were selected randomly as control, while the other l08 mice were injected with STZ 200 mg/kg?bw to induce diabetes.The diabetic mice were divided into 4 groups,the model, MCW (300 mg/kg bw), MCB (300 mg/kg bw), Gilbenclamide (15 mg/kg bw). The above components were administered intragastrically for 10 d and then blood samples were taken to determine concentrations of serum glucose and insulin. Results: The blood glucose levels could be obviously decreased by MCW and MCB in the diabetic mice. MCB has the best antihyperglycemic effect, in terms of improving the serum insulin level and decreasing the blood glucose level of diabetic mice. Conclusion:The polysaccharides from Momordica charantia can repair the injured pancreatic islet tissues and enhance insulin secretion so as to reduce blood glucose level of the diabetic mice.

OBJECTIVE:To investigate the utilization of narcotic analgesics in patients with cancerous pain in our hospital. METHODS:The consumption of Morphine and Pethidine in our hospital in 2004～2007 was analyzed statistically. RESULTS:The consumption quantity of Morphine sulfate controlled-release tablets has been on the rise from 2004 to 2007,while that of Morphine Hydrochloride Injection experienced little change and that of Pethidine Hydrochloride Injection showed a downward trend. CONCLUSION:The structure for the use of narcotic analgesics in our hospital tends to be reasonable,which is basically in line with the Guiding Principle of Pain Relief Ladder for Cancer Pain.

Objective To evaluate advantages of the Herbert screw in treating displaced radial head fractures. Methods The Herbert screw was used to treat 25 segmental fractures of the radial head from since 1991 and the results were compared with those of other treatment methods mentioned in the literature. Results A follow up averaging 6 years and 8 months showed that postoperative function was all excellent or good and that most cases recovered to normal absolutely, without complications. Conclusions The Herbert screw provides such rigid internal fixation for displaced radial head fractures that, after operation, a plaster cast is rarely required and most patients are able to return to work within a few weeks. This method of treatment appears to offer significant advantages over conventional techniques.

Objective To investigate graduate students' common compulsory courses settings of the Military Medical University and put forward suggestions.Methods With self-made questionnaires,we investigate with simple random sampling all the concerned principals of teaching about their opinions of English,politics and statistics courses.Results Most of the experts thought graduate students should not be required to study English but test should be required(68.9％),that politics course was more than required (76.0％),and the percentage of the experts who thought the contents in graduate and undergraduate courses were less overlapped and more overlapped is respectively 47.9％ and 46.6％.Conclusion To satisfy scientific research needs of graduate students in military medical university,the common courses should be reformed,including teaching politics in various methods like lectures,taking software studying and experiment design into statistics,implementing the policy of students taking English test in the exemption of English study,etc.
