This study was aimed to carry out the research by statistics to analyze the influence of specific clinical function of Dioscorea opposita Thunb. from the viewpoint of prescription in order to summarize its rules. Formula containing D. opposita Thunb. in the classic book of the Formula Dictionary of Traditional Chinese Medicine were recorded. The prescription type of D. opposita Thunb. was taken as the mainline. Excellwas used in the chart analy-sis. The results showed that for the function of reinforcing spleen-stomach, the effect of powder was increased, but the effect of pill was reduced. For the function of reinforcing lung and generating essence, the effect of decoction was significantly increased, but the effect of pill was significantly reduced. For the function of reinforcing kidney-yin, the effect of pill was significantly increased, but the effect of decoction was reduced. For the function of strengthening the kidney and restraining yin, the effect of powder was reduced. It was concluded that preparation had a strong in-fluence on the clinical function of D. opposita Thunb., which provided references for both clinical practice and health cultivation.

This study was aimed to optimize extraction process of formula granules of Clematis chinensis Osbeck and establish its qualitative discrimination method. With oleanolic acid, hederagenin and extract rate as indexes, extraction technology conditions of formula granules of C. chinensis Osbeck were investigated by L9 (34) orthogonal test method. TLC was used in the qualitative discrimination of formula granules of C. chinensis Osbeck. The results showed that optimum extraction technology was: adding 12 times of water; soaking for 0.5 h; cooking for 1 h; and extracting for 3 times. TLC had the diagnostic characteristic for the distinct spot which illustrated the specificity. It was concluded that the extraction process was reasonable, simple and feasible with high extraction efficiency of ef-fective contents, which can be the scientific basis for production and quality control of formula granules of C. chin-ensis Osbeck.

This article was aimed to study on clinical application of Shanyao (Dioscorea opposita Thunb.) in each historical period, which can offer some suggestions for clinical doctors to use Shanyao correctly. A total of 668 pieces of formulae containing Shanyao were recorded from the classic format Dictionary of Traditional Chinese Medicine Formula. And then, statistic analysis was made on the emerging frequency according to its effect. The results showed that different effects of Shanyao started to be widely applied from the Song dynasty. It was most widely applied in the Ming and Qing dynasty. Nowadays, the difference between using Shanyao has been gradually decreased. During the whole historical period, clinical functions of Shanyao are mainly reinforcing the spleen and the stomach, tonifying the kidney and strengthening yin. However, clinical functions of reinforcing the kidney and restraining yin, tonifying the lung and promoting fluid are used secondly. It was concluded that the research analyzed clinical application of Shanyao in each historical period, which can offer scientific basis for clinical practice and health maintenance with the using of Shanyao.

Many datas show that thrombosis related events during chemotherapy in patients with cancer increase obviously.Thromboprophylaxis in patients receiving chemotherapy has been shown to not only improve the hypercoagulable states and effectively prevent thrombosis,but also have the potential antitumor effect and prolong the patients over survival.

Objective To evaluate the efficacy of blue-green light phototherapy for jaundice in preterm newborns.Methods Total 124 preterm newborns with birth-weight below 2000 g were included in this study.Infants in group A (gestation age ≤32 weeks or/and instability,n =72) were treated with bluegreen light (group A1 ) or with single side blue light (group A2) randomly.Infants with gestation age ＞32weeks or/and stability (n =52) were also treated with blue-green light (group B1 ) or with single side blue light ( group B2) randomly.Peak levels of serum bilirubin ( PSB),the withdrawal time of jaundice and the duration of phototherapy were compared between groups.Results Group A:PSB of groupAl was lower than that of groupA2 [ (219 ± 31 ) μmol/L vs.( 257 ± 39 ) μ mol/L,P ＜ 0.01 ].The withdrawal time of jaundice group Al was earlier than that of group A2 [ ( 10.3 ±3.0) d vs.( 16.2 ±4.2) d,P ＜0.01 ].The duration of phototherapy of groupA1 was shorter than that of group A2 [ (87 ±34) h vs.(23 ±49) h,P ＜0.01 ].Group B:There were no differences in PSB and withdrawal time of jaundice between two subgroups ( P ＞0.05).The duration of phototherapy of groupB1 was shorter than that of group B2 [ (59 ±23) h vs.(73 ±74) h,P ＜ 0.05 ].Conclusion Blue-green light phototherapy is more effective than single side of blue light in treatment of jaundice in preterm newborns.

Objective To analyze the shortcomings and explore measures in medical nursing to improve quality. Methods The students were divided into experimental group (29 students) and control group (28 students). For the former group, we put a set of new teaching methods, including enhancing students theoretical knowledge and teachers had to prepare well, helping students learn to use the nursing process, sorting out the characteristics and contacting different diseases. After clinical clerkship, we conducted students to follow the case in order to learn more .The latter group received traditional teaching methods. Results The application part and total scores in examination of experimental group were higher than the traditional group (P<0.05). Conclusion The new teaching measures may improve students' learning initiative, communication skills, and develop their clinical thinking.

Objective To explore the relationship between work engagement and job-person fit among nurses.Methods 465 nurses from five first-class general hospitals in Chengdu were assessed by the Utrecht Work Engagement scale(UWES)and the Areas of Worklife Survey(AWS).Results The mean value of work engagement among nurses was (3.21±1.09).Work engagement and job-person fit were positively related.Regression analysis suggested that job-person fits were significant predictors of nurses'work engagement.Exactly,value fit,workload fit,control fit and fairness fit were effective predictors of vigor.Value fit,fairness fit,reward fit and workload fit were effective predictors of dedication.Value fit,control fit,fairness fit and community fit were effective predictors of absorption.Conclusions The work engagement in nurses was at the moderate level.Job-person fits were powerful predictors of work engagement.Good fit among the six areas of work life can improve the work engagement among nurses.
