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 analyze the condition of Rhodamine 123 staining of human bronchial epithelium in vitro during the wound-repair process induced by fluorouracil(5-FU). Methods The bronchial epithelial cells in normal and 5-FU injurious group were obtained by enzymatic digestion and analyzed by flow cytometry.1.PI staining to identify the percentage of cells in different cell phase;2.Rhodamine 123 staining in live cells was to contrast the percentage of negative cells in two groups. Results 1.Analysis of cell cycle:apoptotic cells in injurious group increased,cells in S+G-2/M phase almost disappeared,majority of the remain live cells of injurious group were in G-0/G-1 phase;with the recover of bronchial epithelium,cells in S+G-2/M phase increased;2.The percentage of Rhodamine 123 negative staining live cells in injurious group was higher than that of normal group,and with the recover of bronchial epithelium,this percentage lowered to nearly normal.Conclusion 5-FU can make the cycling cells apoptosis and reserve quiescent phase cells.Among them there were bronchial stem cells which had the capacity to efflux Rhodamine 123.Just the proliferation and differentiation of these stem cells regenerated bronchial epithelium.Rhodamine 123 staining to sort the remain cells after 5-FU treatment by FACS can be used to enrich and purify bronchial stem cells.

[Objective] To observe the therapeutic effect of Shoutai Pill and Shixiao Powder for the treatment of threatened abortion with kidney deficiency and blood stasis. [Methods] Sixty inpatients and outpatients for quieting fetus in gynecology department of the First Affiliated Hospital of Guangzhou University of TCM were equally divided into 3 groups: group A was treated with Shoutai Pill and Shixiao Powder, group B with human chorionic gonadotropin (HCG) and group C with Shoutai Pill, Shixiao Powder and HCG. The effect on quieting fetus was evaluated by observing the disappearance time of symptoms such as vaginal bleeding, abdominal pain, lumbar ache, lower abdominal heaviness and distension. Changes of blood and urine HCG level and type B ultrasonic image were also examined to observe the effect and safety of Chinese medicine. [Results] The effective rate was 95% in group A, 70% in group B and 100% in group C, the difference being significant ( P0.05) . The result of follow-up showed that no terata was found in the three groups. [Conclusion] Chinese medicine with the actions of tonifying kidney and activating blood-stasis can prevent miscarriage and is safe without toxic and side effects.
