Objective To study the chemical constituents from the roots of Euphorbia sonngarica. Methods Compounds were isolated by Sephadex LH-20,MPLC,and silica gel column chromatographies. Their structures were identified by spectral methods together with physicochemical analysis.Results Eleven compounds were isolated from the roots of E.sonngarica.They were identified as cryptomeridiol (Ⅰ),betulin(Ⅱ),betulinic acid(Ⅲ),3?-hydroxy-olean-12-en-28-oic acid(Ⅳ),7-oxo-?sitosterol (Ⅴ),erythrinasinate(Ⅵ),octaeosanoie acid(Ⅶ),1-octacosene(Ⅷ),24-methene-cycloartenol(Ⅸ),eu- phol(Ⅹ),?-sitosterol(Ⅺ).Conclusion CompoundsⅠ-Ⅷare isolated from this plant for the first time.

Membrane proteins are the main undertakers of biofilm function, and also the most important target group for innovative drug discovery and research. About 60% of drugs targets are membrane proteins. Due to the obvious aggregation and denaturation tendency of membrane proteins in aqueous solution, it is difficult to simulate the membrane like environment to maintain the correct conformation of membrane proteins in vitro, which results in the slower-growing research on the structure and function of membrane proteins and related ligand drugs than that of water-soluble proteins. Membrane protein stabilization technology is the premise of establishing high specificity, high sensitivity and high throughput drug screening methods for membrane protein ligands, which is of great significance. In this paper, some techniques for stable separation and purification of membrane proteins are reviewed, including detergents, artificial membranes, polymers, lentiviral particles and so on, as well as their specific applications in drug screening.

Objective Application of the second metatarpophalangeal joint by traction prolong trans- plant repair the defects in the metacarpophalangeal joint,reconstruct the function of it.Methods By means of the apparatus to prolong finger in advance,then transplant the second metatarpophalangeal joint to recon- struct metacarpophalangeal joint for seven cases of obsolete defects in the metacarpophalangeal joint.Results The average of finger prolong was 2.6 cm,consultation from 1 to 4 years.average 2.5 years,thai the trans- plant joints have all survived and osteal concrescence.Through the criterion Chinese Medical Association,good rate was 85.7%. Conclusion It' s a good method to repair obsolete defects in the metacarpophalangeal joint by transplant traction prolong of the second metatarpophalangeal joint.

To prepare salvianolic acid phospholipid compound. With the compound of salvianolic acids and soybean phospholipid as the index, mono-factor experiment and orthogonal design experiment were conducted to screen its technical parameters. According to the results, the optimal preparation conditions of salvianolic acid phospholipid compound were that THF were taken as the reaction solvent, the concentration time was 3 h, the reactant concentration was 5 g x L(-1), the mass ratio of salvianolic acids and phospholipid was 1: 1.5, and the reaction temperature was 40 degrees C. The oil/water partition coefficient of the prepared salvianolic acid phospholipid compound significant increased in water and buffers with different pH values. The results of phase analysis such as DSC, XRD and FTIR indicated that salvianolic acids existed in phospholipid in an amorphous state.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality of AR. This study supplied a new method for the comparison of extract of herbal drugs.

Professor YU Shu-zhuang is a distinguished acupuncturist in China. He has practiced the TCM acupuncture-moxibustion clinical, educational and scientific research for 60 years in his life. In clinic, he summarized the experiences "five-ming first"; in treatment, he insisted "dredging" and "regulating", protecting the function of spleen and stomach, and needles should be less but specific. In the meanwhile, he made a deep study on the function and clinical effects of specific acupoints, and used the research results of propagated sensation along channel to guide clinical treatment, forming his special academic points. Professor YU has educated a great number of acupuncture-moxibustion talents in China and foreign countries, making great contribution to the popularization of acupuncture-moxibustion in the worldwide.
