Objective To explore the value of laparoscopic ovarian-conserving restoration for ovarian cyst torsion . Methods A total of 62 cases of ovarian cyst torsion , 12 of which were combined with pregnancy , between January 2007 and June 2012 were retrospectively analysed .The surgical management involved laparoscopic high ligation of ovary blood vessels , restoration of the ovary, and resection of ovarian cysts . Results All the 62 cases of laparoscopic restoration were successfully performed with ovarian reservation.The cysts twisted for 180°~1080°, including 19 cases of <360°, 21 cases of 360°~720°, and 22 cases of >720°.The cysts were coloured purple black in 26 cases, purple or normal in 36 cases.The operation time was (57 ±23) min, the intraoperative blood loss was 5-130 ml (mean, 50.6 ml), and anal exsufflation time was (24 ±13) hours.No embolism, infection, and abortion occurred during post-operation.The level of estrogen recovered to normal in 1-3 months postoperatively .Ovulation at the procedure side was found in 43 cases in 6-24 months. Conclusions Laparoscopic ovarian-conserving surgery is a safe procedure for ovarian cyst pedicle torsion .High ligation of ovarian blood vessles and resection of ovarian cysts can not only avoid the possibility of thrombosis but also preserve the ovarian functions .The shortage of this operation is complicated to perform .

Purpose:To observe the efficacy of capecitabi ne in the treatment of relapsed breast cancer. Methods:21 patients with relapsed breast cancer were treated. C apecitabine was administered twice a day at the dose of 2 500 mg/(m 2?d) f or two weeks. 21 days was one cycle. Patients could be evaluated after at least 2 cycles treatment. Results:20 patients could be evaluated. There were no complete response but 6 partial response, 8 stable disease and 6 progressive disease in t he group. The response rate was 30.0%. The common toxic effects were hand-foot syndrome (61.1%), nausea and vomiting(66.7%), leucopenia (42.9%) and skin pigm entation (23.8%). Conclusions:Capecitabine is effective for the relapsed breast c ancer patients who have been treated with anthracycline and taxanes. The toxic e ffects are mild and the tolerance is well. Capecitabine can be used as the secon d line regimen for relapsed breast cancer.

AIM: To develop a method of determining notoginsenoside R_1,ginsenoside Rg_1 and Rb_1 contents in Xinnaozhi Capsule(Radix et Rhizoma Notogineseng,Hirudo,Eupolyphaga seu steleophage). METHODS: HPLC was used to determine notoginsenoside R_1,ginsenoside Rg_1 and Rb_1 in Xinnaozhi Capsule.The separation was performed by Zorbax C_(18) colunm with acetonitrile and water using a gradient program at UV 203nm at room temperature.The elution program was 0-3 min,20%-25% acetonitrile,3-15 min,25%-45% acetonitrile. RESULTS: 3 saponins were separated well.Average recoveries were 102.93% for notoginsenoside R_1(RSD=(1.26%));105.68% for ginsenoside Rg_1(RSD=1.52%);104.34% for ginsenoside Rb_1(RSD=0.70%),respectively. CONCLUSION: The method is simple and rapid and with satisfactory results.It is suitable for quality control of Xinnaozhi Capsules.

Objective A HPLC method to determine the content of Baicalein in Tangtai capsule was established. Method The separation was performed by Zorbax C18 column with acetonitrile and 0.5% phosphorice acid. The elution program was 1~15 min, 15%～60% acetonitrile. The flow rate was 1 mL/min and column temperature was 25 ℃. Content was detected at a wavelength of 280 nm. Result The linear range was 0.936～18.72 ?g, regression:Y =4849.53X-0.9593 (r=0.9999). The average recovery rate was 98.29% and RSD was 0.97% (n =5). Conclusion The method is simple, accurate and reproductive, and can be used for determining Baicalein in Tangtai capsule.

Objective To investigate urban residents’ willingness-to-pay (WTP) for ambient air pollution control to avoid the adverse health effects in Qingdao, China. Methods A contingent valuation method (CVM) was employed and a sample of 1 050 residents was randomly chosen, 21st to 27th January, 2007. A series of hypothetical, open-ended scenario questions were designed to elicit the respondents’ WTP with face-to-face interviews. A Probit model on the probability of a positive WTP and a stepwise regression model were established to find the relationship between endogenous variables and WTP. Results 1 008 valid questionnaires were obtained. 73.9% respondents believe that air pollution had adverse effects on health. 54.6% respondents cost 100 to 500 Chinese Yuan (CNY) on treatment of respiratory diseases for their whole family. 94.2% respondents were able to express positive WTP and the median WTP was 600 Chinese Yuan (CNY) per household per year. Conclusion Urban residents’ aggregate WTP accounted for 1.25% of annual household income and 11.9% of government investments for air pollution control in 2005. Residents’ age, job and household income variables had significant influence on the probability of a positive WTP. Residents’ household income, education level, expenditure on treatment of respiratory diseases and age significantly influence WTP value.

Objective To evaluate the outcomes after implementing gestational diabetes mellitus(GDM) specialist practice model. Methods GDM specialist practice model contained four modules(first visit,follow-up visit,hospital-ization,postpartum),eight aspects of practice contents which included specialist evaluation,diet & exercise survey, diet & exercise prescription,GDM health guidance,weight management during pregnancy. Pregnancy outcomes were compared before and after GDM specialist practice. Results GDM specialist practice model was able to signifi-cantly decrease insulin utilization rate,reduce number of hospitalized patients due to poor blood sugar control,short-en length of hospitalization. Conclusion GDM specialist practice model can effectively save medical costs,and GDM specialist nurses play an important role in management of women with GDM.

Studies on the prescription combination regularity based on medicinal tastes focus on the internal relations between the structure and hierarchy of the prescription combination system. In this paper, with the systematic and scientific self-similarity theory as the core ideology, authors systematically interpreted the self-similarity theory of medicinal properties, defined the self-similarity of prescriptions with identical or similar medicinal properties, and built the systematic view of medicinal property theory based on the prescription combination based on the entity grammar system. As a result, the system was conducive to integrating traditional Chinese medicinal knowledge of syndromes, therapeutic principles, efficacies, medicinal properties and tastes and achieving the automatic design and optimization process from symptoms to prescriptions, and providing scientific and feasible methods and technical systems for the application of the medicinal property theory, with a guiding significance to the technology, methodology and theory of decoction pieces compatibility, component compatibility and compound medicine design.

Objective To investigate the methods of isolating collagen from different shark skins and to study its biochemical properties.Methods The collagen from the Blue shark scalp was extracted and purified by enzymolysis after treatment with diluted caustic alkali,and the collagen from the Spanish mackerel skins was extracted and purified by phosphate buffer method,respectively.Subsequently,the relative molecular mass,thermal denatured temperature and secondary structure of extracted collagen were determined.Results The extracted collagen with a yield of 2.9%～4.1% showed three clear bands by SDS-PAGE,and the relative molecular mass were 205,134 and 118KDa.The collagen from Blue shark and Spanish mackerel skins maximal thermal denatured temperature was 69,47℃,respectively.The secondary structures of their collagen were primary with ?-sheet and the random structure,without ?-alix.Conclusion The purified collagen was also extracted by the method of enzymolysis after treatment with diluted caustic alkali and the method of phosphate buffer.The relative molecular mass and the composition of Blue shark collagen and Spanish mackerel collagen were limited.However,the different extracted conditions could affect the specifically biochemical properties of thermal denatured temperature and secondary structure of collagen.
