Objective To propose new policies and strategies that will optimize the transformation of medical research achievements at hospital level.Methods In this paper,we systematically analyzed the characteristics and influencing factors of the transformation of medical research achievements based on the status quo in our hospital.Results In our hospital as an example,major problems in the transformation of medical research achievements identified as low investment,low conversion rate,complex procedures,multi-links existed and more multi disciplinary cooperation needed.Conclusions The hospital can take some measurements to optimize the transformation of medical research achievements,such as more stream lined management of scientific research project,establishing and improve the platform for scientific research transfer,increasing the funding,strengthening cooperation among different disciplinaries,building a professional team to promote the transfer and so on.

To control the quality of Maca, the quality standard was established in this study. According to the methods recorded in the Appendix of Chinese Pharmacopoeia (2010 Edition), the water, extract, total ash, acid insoluble substance, and heavy metals inspections in Lepidium meyenii were carried out. N-benzyl-9Z, 12Z-octadecadienamide in L. meyenii was identified by TLC, and it was determined by HPLC. The results showed that the N-benzyl-9Z, 12Z-octadecadienamide identification of TLC was a strong mark and specificity. In content determination experiment, the linearity of N-benzyl-9Z, 12Z-octadecadienamide was in the range of 0.01-2 microg (r = 0.9998), and the average recovery (n=9) was 99.27% (RSD 2.0%). The methods were simple, accurate, with good reproducibility. It is suitable for quality control L. meyenii.

Background and purpose:Chemotherapy plays an important role in the treatment of breast carcinoma by inhibiting the tumor growth and inducing the apoptosis.MAPK transduction pathway is closely related to proliferation and apoptosis of varieties of tumor cells,inhibition of MAPK pathway may increase the efficiency and decrease the toxicity of chemotherapy.Our study was to investigate the effect of MEK inhibitor PD98059 in response of breast cancer cell lines to Epirubicin.Methods:Human breast cancer cell lines MCF-7 and MCF-7/ADR were used as cell models.Epirubicin(EADM),PD98059(inhibitor of MAPK Kinase-MEK),or EADM+PD98059 was added into the culture medium,the expression of MEK2 and p-ERK were measured by Western blot,the growth of the two cell lines were measured by MTT.Results:ERK activity was elevated in MCF-7 after the treatment of EADM,the cells were more sensitive to EADM if combined with PD98059,while in MCF-7/ADR,ERK activity kept unchanged after EADM treatment,and PD98059 has no effect on the sensitivity of cells to EADM.Conclusion:MAPK signal transduction may be activated in some cells treated by EADM,adding inhibitor of MAPK signal transduction could improve the sensitivity of the cells to EADM.

Based on analyzing image edge cloning theory and algorithms, a marginal clone algorithm is proposed with a combination of edge connectivity and noise removal algorithm. Simulation results show that the edge image detected by the algorithm has solved problems of traditional edge discontinuities and tsereve noise. Moreover, it has better edge recognition performance.

Objective To assess the changing trend of serum uric acid (SUA) levles in health check-up subjects of Tianjin municipality 2007-2015.Method Data were collected from 266 043 subjects receiving annual health check-up from 2007 to 2015 in Tianjin municipality.Changing trends of SUA levels and incidence of hyperuricemia were analyzed during the 9 year period.Results From 2007 to 2015 SUA levels in males were increased from (347 ± 73) μmol/L to (373-± 78) μmol/L,while in females were increased from(253 ± 59) μmol/L to (267-± 61) μmol/L.The trend test showed that both for men and woinen the incidence of hypemricemia was increased in each year (men:x2 =270.30,women:x2 =15.10,both P =0.00).The incidence of hyperuricemia by each year was increased more markedly in men than that in women (x2 level:194.80-1 877.00,all P =0.00).The incidence of hyperuricemia in young adults (20-39) was higher than that in middle-ages (40-59),and the latter was higher than that in elderly (＞ 60).For the 7-year (2009-2015) incidence of hyperuricemia in young and middle-aged men,the trend test showed statistical siganificance (x2 level:14.11-233.90,all P =0.00).By contrast,the incidence hyperuricemia in women was increased with aging,and for the 9-year incidence of hyperuricemia in young women,the trend test showed statistical siganificance (x2 level:115.30-480.20,all P =0.00).Conclusion The incidence rates of hyperuricemia are high in Tianjin health check-up subjects,especiallly in young males and old females.There is a time trend of increasing incidence of hyperuricemia in the young and middle-aged subjects.The results indicate that the prevention and control of hyperuricemia in Tianjin are of clinical and social significance.

Objective To investigate the relationships between different dietary patterns and serum uric acid in Tianjin residents. Method By cross-sectional study design, 11282 subjects were studied via lifestyle questionnaires (including a valid food frequency questionnaire), physical examination and laboratory tests. Using factor analysis method to establish the dietary patterns, and relationships between different dietary patterns and serum uric acid were analyzed. Results Factor analysis showed 3 kinds of dietary patterns, including eastern dietary pattern, vegetable diets and Tianjin dietary pattern. There were more males in hyperuricemic population, who have a higher BMI, waist circumference, blood lipids, blood pressure and blood sugar levels, and also higher proportion of metabolic syndrome, smokers and alcohol drinkers. In addition, hyperuricemia patients had a higher level of social status and income. After adjustments for age, sex, BMI, smoking habits, alcohol consumption, hypertension, hyperlipidemia, education level, occupational status, energy intake, physical activity and metabolic syndrome, logistic regression analysis showed the odds ratio (95%confidence interval) for hyperuricemia across the quartiles of 3 dietary patterns as follows: 1.00, 1.07 (0.91, 1.25), 0.96 (0.82, 1.14), 1.12 (0.94, 1.33);1.00, 1.03 (0.88, 1.21), 1.04 (0.88, 1.23), 1.00 (0.84, 1.19); 1.00, 1.28 (1.08, 1.52), 1.40 (1.22, 1.71), 1.37 (1.15, 1.63), respectively. Significantly positive correlation was shown between Tianjin dietary pattern and hyperuricemia. Conclusion Tianjin residents' Tianjin dietary pattern is closely related to serum uric acid levels. Tianjin dietary patterns have characteristics of high calorie, high fat, high protein. Healthy eating habits have significant importance to prevent occurrence of hyperuricemia.

Technological improvement for microorgnism isolation is important since isolation provides substantial materials for the exploitation of new microbial resources. In this study, a new approach, dispersion and differential cetrifugation (DDC), was applied in the isolation of acidophilic and acidoduric streptomycetes from 12 acid soil samples. Contrast with traditional method, the new approach yielded satisfying results with 2 - 20 times isolation efficiency and good selectivity. 45 representatives out of 249 streptomycetes isolates, which belonged to 12 color groups, showed morphology and cell wall type consistent with streptomycetes. The optimum pH range for their growth were between pH 4.5 - 5.5. It is proved that we succeeded in the rare-streptomycetes isolation using DDC approach.

Objective To analyze the relationship between body weight index (BMI) during the different pregnant weeks and the birth weight of newborns. Methods One hundred pregnant women and newborns were selected. BMI in every month during the pregnancy period, birth weight and height were observed and recorded. Then the relationship between BMI of pregnant women and birth weight of newborns was analyzed using Peas,son correlation coefficient. Results The correlation between BMI of pregnancy from the fifth month to the ninth month and the birth weight of newborns had significantly statistical meaning, especially the correlation between BMI of the fifth, the sixth and the eighth months and the birth weight of newborns were more obvious, each showing a positive correlation. Conclusions The higher the BMI of pregnant women, the higher the birth weight of newborns. Therefore the pertinent diet guidance should be given to the pregnant women in the middle to late stages of pregnancy according to the pregnant women's BMI, in order to reduce the incidence of enormous infants and premature infants.
