Objective:To explore the effect of different separation and purification technology on the physical and chemical proper-ties of water extract of ophiopogonin. Methods:The water extraction process of total ophiopogon saponins was optimized by an orthogo-nal test. The macroporous resin adsorption and membrane separation technology were adopted to purify the ophiopogonin water extract. The physical and chemical parameters, such as electrical conductivity, pH value, viscosity and turbidity, and the contents of total sap-onins, proteins, tannins and polysaccharides were determined. Results:The optimum water extraction technology of total saponins was as follows:6-fold amount of water was added, boiling 3 times with 90 min for each time. The electrical conductivity, pH value and vis-cosity of different purified liquid of total saponins had no significant differences, while the contents of total saponins and the three kinds of macromolecules showed significant differences. Conclusion: The content of macromolecules can be used as the reference index of purification process of total saponins water extract. Compared with macroporous resin separation, membrane separation technology is more suitable for the separation and purification of total saponins water extract.

Objective Analyzing the impact of teachers' background characteristics on the Students' evaluation to improve the quality of teaching from the angle of the teachers professional development. Methods Based on the data of students' evaluation of teaching of Shanghai medical college of Fudan University from 2008 to 2011, the article analyzed the teachers' gender, age, job title, diploma, and other relevant background characteristics. Excell2007 was used to build dataset and the data was analyzed statistically by software of SPSS 11.0 and expressed with x±s. The statis-tical method of one-way analysis of variance was used to compare the teachers with different genders, education backgrounds, ages and professional titles, showing statistically significant difference (P<0.05). Results comparative analysis showed that no statistically significant differences existed in fac-ulty teaching evaluation scores among the teachers of different genders or different education back-grounds(P=0.613 9、0.891 0). There were however significant differences in teaching evaluation of teachers of diverse ages and professional ranks(P=0.017 3 and P=0.032 5). Conclusions According to the analysis results of faculty teaching evaluations, associate professors' teaching evaluation scores were lower than intermediate grade teachers', and the score of the teachers between the age of 41 to 45 was lower than that of the teachers between the age of 36 to 40. Therefore individual variations and various social backgrounds of teaching faculties should be taken into consideration and the corre-sponding countermeasures for the professional development of teachers should been put forward. In addition, the cultivation of new teachers, young and middle-aged teachers should be strengthened, and the proportion of teaching evaluation in the Performance Appraisal should be increased.

To optimize the water extraction process for glycyrrhiza. Methods: HPLC was used to determine the con-tents of glycyrrhizic acid and liquiritin. The comprehensive index included the contents of glycyrrhizic acid and liquiritin and the yield of dry extract. The water amount and the extraction time were selected as the independent variables, and the comprehensive index was set as the dependent variable. Design-expert 8. 06 software was used to fit multivariate linear or quadratic multinomial models for the experimental values. Response surface methodology was used to optimize the water extraction process. The prediction was carried out through comparing the observed and predicted values. Results:The regression coefficient of binomial fitting complex model was as high as 0. 979 7. The optimum conditions of extraction process were as follows:12-fold amount of water, extracting 3 times with 90 min for each time. The deviation between the observed and predicted values was -1. 72%. Conclusion: Central composite design-response surface methodology is convenient and highly predictive in optimizing the water extraction process for glycyrrhiza, which can be applied in the further membrane separation and purification.

2 mmx3 mm experimental windows were prepared in adamant slippery surfaces of 7 fresh uprooted permanent teeth. The teeth surfaces in the windows area were demineralized to create artificial caries mould of early stage by aciding the experimental teeth surfaces of 0, 12, 24, 48, 72, 96, 120 hours with demineralized liquid (pH 4.5) in vitro. The demineralized changes on the experimental teeth surfaces were detected by dental Optical Coherence Tomography (OCT) system, which were newly developed by our research group recently, and the detecting results were compared with clinical digital photomicrography and scanning electron microscopy on the same tooth sample, to checkout the efficacy and feasibility of dental OCT for early quantification detecting of artificial enamel demineralization in vitro. The dental OCT system can safelydetect early enamel demineralization of micron level and noninvasively obtain fine resolution quantification information both in surfaces view and sectional view; OCT could accurately detect surface demineralization changes on the experimental windows of artificial dental caries as early as after 12 hours aciding treatment, earlier than the visual inspection and clinical digital photomicrography. OCT could obtain both superficial view and sectional view of quantificational demineralization in early enamel caries homeochronously, and had high correlation to the results of ultramicromorphological changes detected by scanning electron microscopy. Dental OCT system developed by our group could accurately detect early artificial dental caries atraumaticly with high sensitivity and safety. Moreover, it can obtain quantification data in micron level without damaging the experimental teeth samples.
