Objective To construct a scientific and feasible evaluation indicator system of health education effect of our country′s hospitalized patients with diabetes. Methods On the basis of literature review and semi-structured interview combined with group discussion, alternative index system were determined,and then the Delphi method were used for two round consultation with 30 diabetes experts to finally determine indicator evaluation system. Results Positive coefficient of the two rounds consultation were 86.7% (26/30) and 100.0% (26/26) respectively, experts′ authority coefficient was 0.889,and the Kendall W coefficients of concordance were 0.447,0.369 and 0.302 respectively (P<0.01). The evaluation indicator system of health education effect was consisted of 6 fisrt-level indicators, 24 second-level indicators and 55 third-level indicators. Conclusions The evaluation indicator system of health education effect is reliable and scientific, which can provide objective and quantitative standards for health education effect of hospitalized patients with diabetes in our country.

Research topics,ideas and contents of NSFC funded projects are generalized and characteristics,problems and future trends are also analyzed to provide reference for research on drug toxicology.

Objective To transfect PCDNA3.0-HIF1-? into the endothelial progenitor cells(EPCs),in order to provide the foundation for exploring myocardial vascular repairing capacity and angiogenesis of the EPCs transfected with HIF gene.Methods The EPCs were separated by the method of density gradient separation in the human bone marrow,and then the cells were inoculated in the fibronectin-packaged petri dishes complete medium with the concentration of 1?106?mL-1,and cultivated for 14 d. The expressions of the endothelial cell-specific components ecNOS and flk-1 were detected with RT-PCR; the cells were stained with acLDL-Dil and FITC-UEA-1; the PCDNA3.0-HIF1-? plasmid was transfected into the EPCs mediated by LipofectamineTM 2000,the transcription of HIF1-? was determined with RT-PCR; the expression of VEGF was detected with enzyme-linked immunosorbent assay (ELISA); the expression of HIF1-? was detected with Western blotting.Results After cultivated for 5 d,some round monocytes transformated into spindled inherent EPCs;7 d later,there were some cell colonies containing dozens of cells;10 d later,there were obvious cell clones; RT-PCR showed ecNOS band in 548 bp,flk-1 band in 819 bp; acLDL-Dil and FITC-UEA-1 double-staining was positive; RT-PCR showed specific band in 383 bp; ELISA showed the content of VEGF in the supernatant of EPCs transfected with HIF1-? was (20.53?2.33) ?g?L-1,and it was (3.96?1.67) ?g?L-1 in the EPCs transfected without HIF1-?,there was significant difference between two groups (P

Caenorhabditis elegans is a very important model organism in life sciences. C. elegans has been widely used in research on life sciences, especially in drug screening and the mechanism of drugs, thanks to some of their prominent characteristics, including a short life,short generation cycle, and easy culture and observation. Aging is a complex process, which is the result of multiple factors. There are mainly three types of anti-aging signal pathways in C. elegans, including insulin-insulin-like growth factor-1 signal pathway, diet-restricted signaling pathway and mitochondrial respiratory chain/ATP synthesis pathway. In this paper, we reviewed the aging models based on the above three signaling pathways and the progress in anti-aging drugs based on the above aging models. In addition, a number of C. elegans models of aging-related neurodegenerative diseases can be obtained by using transgenic or chemical mutagenesis. Thus, this paper reviewed the transgenic models of C. elegans associated with neurodegenerative diseases, including theα-synuclein transgenic model of Parkinson disease, theβ-amyloid deposition model of Alzheimer disease, and the polyQ of Huntington disease, and summa?rized the effective drugs based on the above disease models. This review will provide reference for the study of C. elegans in the future screening of anti-aging drugs and drug screening for the prevention and treatment of neurodegenerative diseases.

This paper focuses on the current situation of web-based teaching in medical genetics through the analysis of its advantages and characteristics.The prospects and problems of web-based teaching are also discussed.

Paget's disease of the breast is an uncommon disorder that accounts for 1% to 3% of all mammary tumors. The incidence of underlying carcinoma associated with Paget's disease has been reported in 82% to 100% of cases. The finding of underlying carcinoma reaches almost 100% when a palpable lump is also present. In this rare case, we described a patient presenting with Paget's disease but no palpable lump. However, we found 11 independent regions which were all invasive ductal carcinoma after the operation. Considering this patient, we should pay more attention to a multifocal and multicentric breast carcinoma associated with Paget's disease. Furthermore, we believe the mammography examination and a modified radical mastectomy are the most appropriate treatments for this population in clinical practice.

Objective To investigate hospital acquired infections in patients with liver cirrhosis caused by relevant factors.Methods From July 2008 to June 2013,the clinical data of 470 cases of hospital acquired infections patients with chronic hepatitis B virus (HBV) infection were retrospectively analyzed by case-control study for the effective factors.Results Hospital acquired rate was 29.1％ (137/470).By logistic regression analysis,the effective factors were length of stay (OR =27.824,95％ CI 7.187-98.386),invasive operation (OR =17.201,95％ CI 4.245-71.303),a complication (OR =2.138,95％ CI 1.030-4.377),preventive use of antibiotics(OR =2.741,95％CI 1.816-4.010),drinking history(OR=34.248,95％CI 13.045-82.328),serum albumin(OR =17.258,95％ CI 6.242-53.162),quantitative PCR-HBVDNA (OR =4.859,95％ CI 3.214 -7.625),white blood cell (OR =4.271,95 ％ CI 1.520-12.157),c holinesterase (OR =2.761,95 ％ CI 1.523 -3.787) and anti virus medicine(OR=0.128,95％CI 0.041-0.375) (P＜0.05).Conclusion This study shows that length of stay,invasive operation history,complications,low white blood cell,low serum protein,low cholinesterase,the prophylactic use of antibiotics,hormone,high PCR-HBVDNA quantitative and drinking are the important risk of hospital acquired infections infection factors of patients of impact chronic HBV infection.Applications of antiviral drugs are effective in the prevention of chronic HBV infection protection factors of hospital acquired infections infection patients.

Objective:In order to study the morphological diversification in heterotopic liver auxiliary transplantation(HLAT). Methods:HLAT model in rats was established, the status of rats survival and graft function was evaluated postoperatively by rheometer, SPECT electrical microscope etc. Results:Rat HLAT model was feasible, the operative success rate was 93.3%, one week postoperative survival rate was 80%,the survival time without complications was more than 3 months. The function of the native liver was not affected, as the time goes by, the graft become atrophic after 45 days postoperatively. Conclusion:In HLAT model, the function of the native liver was not affected, 45-days-after the transplantation, the graft become atrophic.

Mimecan belongs to a family of leucine-rich proteoglycans that are secreted into the extracellular matrix. In order to investigate the function of mimecan, the coding region of mimecan was amplifed from a human pituitary cDNA by PCR and the recombinant prokaryotic expression vector pGEX-M was constructed. The vactor was transformed into E.coli BL21(DE3)and the GST-M fusion protein of 38 Kd was ecpressed in the bacteria under induction of IPTG. After purification, the fusion protein was infucted into New Zealand rabbits to prepare polyclonal antibody. The antibody was tested by Western blotting for their specificity and sensitivity. Using the antibody it was found the mimecan was expressed highly in certain types of human pituitary tumor tissues. These results make it possible for studying the biological function of mimecan.
