Objective: To find out the current situation of the reproductive health about countrywomen in west of China,and explore the factor of the reproductive health under social medicine theory framework.Methods: Summarize literature about women reproductive which have been done recently,and do 608 samples survey in Xi'an of Shaanxi,which is about the current situations of social economic,reproductive health,gynecological diseases and mental health.Results: The research clarified the primary connotation about the reproductive health of countrywomen,and identified the current situation of countrywomen reproductive health in Shaanxi province of China.Conclusion: The situation of countrywomen reproductive health is far away from the demand of strategic target of "Everyone enjoys the reproductive care since 2015",and the countrywomen are on the hip in birth control,bearing culture,acquirement of health knowledge and primary diathesis.

Objective To build an evaluation index system of medical practitioners'competency for county-level public hospitals. Methods By means of the Iceberg Model based on competence and professionalism, and following two rounds of consultations of 47 experts, the evaluation indexes and weights of medical practitioners' competency were determined using SPSS frequency, mean, Kendall harmony coefficient and factor analysis. Three county-level public hospitals in Shaanxi province were selected for example verification of service competency. Results The evaluation index system of county-level public hospitals included 4 level-1 indexes and 16 level-2 indexes. The 4 level-1 indexes were diagnosis competency, treatment competency, communication competency and self-development competency. The weights of these indexes were 0.3,0.3,0.2 and 0.2 respectively. Conclusions Such hospitals should start with these competencies to strengthen the cultivation of medical practitioners' competency and constantly improve their comprehensive service level.

ObjectiveTo identify Dendrobium flexicaule and its related species， and analyze the differences in polysaccharide composition and D-mannose content， so as to provide theoretical basis for the accurate identification and quality control of Dendrobium medicinal materials. MethodNine samples of Dendrobium （S1-S9） were identified by DNA barcoding and infrared spectroscopy， and the contents of polysaccharides and D-mannose were determined by ultraviolet spectrophotometry （UV） and high performance liquid chromatography （HPLC）， respectively. UV detection condition was 488 nm， HPLC detection conditions were the mobile phase of 20 mmol·L^-1 ammonium acetate solution-acetonitrile （81.5∶18.5） and the detection wavelength at 250 nm. ResultDNA barcoding results showed that samples S1-S3 were D. nobile， samples S4-S5 were D. officinale， sample S6 was D. huoshanense， and S7-S9 were D. flexicaule. One-dimensional infrared spectroscopy showed that only D. nobile had stable characteristics at the wavenumber of 1 570-1 467 cm^-1， showing a "W" shape， while no absorption peak was found at the wavenumber of 842-740 cm^-1， but the other Dendrobium samples had stable absorption peaks at the wavenumber of 842-740 cm^-1. In the first derivative spectrum， at the wavenumber of 785 cm^-1， D. huoshanense presented a "V" shape， while the rest of Dendrobium presented a "W" shape. At the wavenumber of 1 110 cm^-1， D. flexicaule had a stable characteristic peak. In the second derivative spectrum， at the wavenumber of 1 125 cm^-1， D. officinale presented an "M" shape， and the rest of Dendrobium was approximately "W" shape. The results of determination showed that the contents of polysaccharides in samples S1-S9 were 9.35%， 9.12%， 32.78%， 49.38%， 48.97%， 32.48%， 32.95%， 39.41% and 25.32%， and their contents of D-mannose were 1.39%， 0.47%， 13.57%， 3.04%， 33.85%， 23.57%， 16.64%， 17.47% and 19.49%， respectively. Among them， D. flexicaule had high polysaccharide and D-mannose contents. ConclusionBoth DNA barcoding and infrared spectroscopy can be used to identify D. flexicaule and its related species， and infrared spectroscopy is cost-effective and easy to operate. At the same time， D. flexicaule has high contents of polysaccharides and D-mannose， which can provide a scientific basis for rapid identification of D. flexicaule and its relatives， and provides a reference for its quality control， and resource development and utilization.
