AIM To establish a RP-HPLC method for the simultaneous content determination of four constituents in Canarii Fructus.METHODS The analysis of Canarii Fructus methanol extract was performed on a 30 ℃ thermostatic Hypersil ODS column (4.6 mm × 200 mm,5 μm),with the mobile phase comprising of acetonitrile0.1％ phosphoric acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 237 nm.RESULTS Gallic acid,protocatechuic acid,chlorogenic acid and epicatechin displayed good linear relationships within the ranges of 0.525-10.500 μg/mL (r =0.999 9),0.700-14.000 μg/mL (r =0.999 9),0.575-11.500 μg/mL (r =0.999 9) and 0.550-11.000 μg/mL (r =0.999 9),whose average recoveries were 99.05％ (RSD=1.4％),98.73％ (RSD=0.8％),98.69％ (RSD=1.3％) and 99.47％ (RSD=1.1％),respectively.CONCLUSION This simple,sensitive and relible method can be used for the quality control of Canarii Fructus.

To compare the merit and shortcoming of treatment and securities with absorbable implants and metallic fixation for fractures of the ankle,45 patients with ankle fractures were enrolled from the the Fifth Hospital of Dalian between February 2000 and May 2004 and treated with absorbable implants(n =21)and metallic fixation(n =24),respectively.All patients were available for an average duration of follow-up of 10-18 months.The results were evaluated by radiographic representations and joint function and showed that all the patients were healed in ankle fractures.The total rate of good and excellent results was 92%(19/21)in absorbable implants group and 92%(22/24)in metallic group.There were no statistic differences between these two methods.Absorbable implants is believed to be a good method for the treatment of ankle fracture instead of metallic implants.

Objective To study the expression and signficance of the osteopontin (OPN) in epithelial ovarian cancer tissue and serum. Methods Immunohistochemistry method and ELISA were used to detect the expression of OPN in 64 cases of epithelial ovarian cancer tissue and serum, 20 cases of ovarian benign tumors and 10 cases of ovarian nomal tissues. Results The OPN expression was associated with the clinical staging and histological grading of epithelial ovarian cancer tissue and serum (P < 0.01). The level of OPN in epithelial ovarian cancer tissue was significantly higher than that in benign ovarian tumor and normal control groups (P < 0.01). Conclusion OPN is remarkably correlated with the carcinogenesis and the development of epithelial ovarian cancer.

Objective Through a survey of medical students in autonomous learning, to understand students' learning motivation and learning strategies and find out the existing problems, and to provide the basis for the school to organize autonomous learning and improve the teaching quality. Methods Convenient sampling method was used to extract 1 500 students' autonomous learning scale who were freshman and sophomore, junior students and 1 467 valid questionnaires were collected. According to the corresponding research situation of Zhejiang Normal University, SPSS 19.0 was used to compare the different types of students in the school, and the t test or q test were also done. Results The situation of college students' autonomous learning was better. The girl's average score was (312.51 ±14.03) which was higher than the boys in the school (286.16 ±13.69)and the girls in the control group (302.67 ±10.37). The difference was statistically significant (P<0.05). The average total score of the junior college students (307.92 ±13.84) was better than that of freshman and sophomore (P<0.05), which suggested that junior students had the strongest independent learning ability. Conclusion Colleges and universities should be based on the actual situation of students and formulate corresponding policies and measures from the autonomous learning motivation, the boys dor-mitory management, to ensure the stability of teaching quality improvement.

Objective To research the feasibility of the prefabrication of skin flap with frozen allogeneic bone.Methods From November 2010 to July 2011,fifteen miniature pigs were randomly divided into three groups(n =5) according to different implanted positions.Rewarming,deep-frozen allogenic bone was implanted in subcutaneous tissue,subfascial compartment and muscle respectively.Emission Computed Tomography (ECT) was used in the 4th week,the 8th week and the 12th week postoperatively.Angiography and pathological examination was used in the 12th week.Results The difference of the result of ECT was statistically significant betweent the 4th week and the 8th week (P ＜ 0.05),and there was not statistically significant difference betweent the 12th week and the 8th week (P ＞ 0.05).Angiography showed that all allogeneic bone was vascularized in each group.Pathological examination showed that the vascularization and the inducing osteogenesis of the allogeneic bone which was implanted in the subfascial compartment or muscle was better than that in the subcutaneous tissue.Conclusion The deep-frozen allogenic bone can be used for the prefabrication of the bone-skin flap.

Objective To investigate the expression of osteopontin ( OPN) in epithelial ovarian cancer tissue and its prognostic value. Methods The immunohistochemistry method was used to detect the expression of OPN in 64 cases of epithelial ovarian cancer tissue, and 20 cases with ovarian benign tumors and 10 normal ovarian tissues as well. The relationship between the OPN expression and clinical pathological characteristics and its prognostic value were analyzed statistically. Results The positive expression of OPN case was confirmed in 52 cases in 64 epithelial ovarian cancer. The expression level of OPN in epithelial ovarian cancer tissue was significantly higher than that in benign ovarian tumor and normal control (P <0. 01). The OPN expression in epithelial ovarian cancer tissues was associated with the pathological grading, lymphatic metastasis and production of ascites. The survival time is longer in OPN negative patients than the positive group. Conclusions OPN plays an important role in the tumorgenesis and development of epithelial ovarian cancer and correlates with its prognosis.

Objective To evaluate the quality of life and influencing factors in patients with breast cancer after breast-conserving surgery, so as to provide theoretical support for preoperative health education and postoperative rehabilitative intervention for these patients. Methods 120 breast conserving surgery (BSC) and 140 modified radical mastectomy (MRM) patients were assessed with Functional Assessment of Cancer Therapy-Breast (FACT-B V4.0) one week after operation. Life quality was evaluated between the two groups, and the influencing factors were also analyzed. Results Postoperative breast cancer patients after breast conserving surgery were with good breast complementary attention, lower emotion state. The other scores of quality of life had no statistical difference. Influencing factors on the quality of life of breast cancer patients were anxiety state, relationship of family members, position of surgery and character type. Conclusions It suggests that nursing specialists should make out corresponding, scientific and reasonable nursing intervention schemes based on the characteristics of different groups of people to ease psychological burden, and elevate the quality of life effectively for postoperative breast conserving surgery patients.
