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 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.

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.

Objective To investigate the impact of propofol and midazolam on the time course of extubation in patients with mechanical ventilation.Methods The patients were randomly divided into the propofol group(n=37)and the midazolam group(n=52),which were further divided into three sedation stratums.The administration of two drugs were stoped immediately while weaning from the ventilator.The awakening time and extubation time of the two groups were recorded and compared with each other.Results Both awakening time and extubation time of the propofol groups were shorter than those of the midazolam group(P

As two main research methods, qualitative study and quantitative study are different in theoretical basis, research methods, research goal, the relation between researchers and those who are studied as well as applied fields. They should be combined in education research, however, for education is a complicated humanism phenomenon.

OBJECTIVE:To optimize the factors of preparing pheophrobide from silkworm excrement and raise the yield of pheophrobide.METHODS:Based on the extraction rate of chlorophyll,acetone method was compared with alcohol method and the preparing factors of acetone method was optimized by orthogonal design.RESULTS:The best conditions for pheophrobide preparation included grinding silkworm excrement into powder with particle size all below 250μ m,softening the powder more then 5h with water 1/10 the volume of powder,extracting the powder with acetone three times the volume of powder at 70℃ for two times 60min each,regulating pH of the liquid to 2.5 with HCl solution.CONCLUSION:The water and acetone volume was more important than other factors,the yield of pheophrobide was raised 3.6 times after optimization

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.
