Objective:To study the dissolution behavior of panax notoginseng saponins R1 , ginseng saponin Rg1 and ginseng sapo-nin Rb1 in Xuesaitong soft capsules in two different dissolution media. Methods:The dissolution test conditions were confirmed accord-ing to“quality of medical drugs information set” of Japan and the dissolution media were chosen in accordance with the physicochemi-cal properties of Xuesaitong soft capsules, the in vitro dissolution of Xuesaitong soft capsules was inspected respectively in pH 6. 8 phosphate buffer and water. The dissolution rate was determined by HPLC-ELSD, and the similarity of the release curves for the three components was compared with similarity factors ( f2 ) method. Results: The assay displayed a good linearity over the concentration range of 0. 8-16. 0 mg·L-1(r=0. 999 6), 3. 0-60. 0 mg·L-1(r=0. 999 8) and 4. 0-80. 0 mg·L-1(r=0. 999 7) for panax notog-inseng saponins R1 , ginseng saponin Rg1 and ginseng saponin Rb1 , respectively. In pH 6. 8 phosphate buffer and water, f2 of ginseng saponin Rg1 and ginseng saponin Rb1 were both above 50 when compared with panax notoginseng saponins R1 . Conclusion:The meth-od is simple, accurate and reproducible in the dissolution determination of the soft capsules. The dissolution of ginseng saponin Rg1 and ginseng saponin Rb1 has similar characteristics with that of panax notoginseng saponins R1 in Xuesaitong soft capsules.

Objective: To explore the quality of life of children with behavior problems. Method: A sample of 2087 children were administered Conners Scale and Inventory of Subjective of Life Quality, then we compared the quality of life of normal children with that of children with behavior problems. Result: Children with behavior problems had poorer life quality than normal children. Stepwise regression revealed that seven variables offacted subjective satisfaction of the children, including academic achievement, behavior problems, economic condition of the family, father's personality, age, parental coping style for poor behavior, single child family. Conclusion: Behavior problems of children are also problems of the family.

The immunoregulation effect to polysaccharides from Bifidobacterium spp. was investigated on the base of functional assessment standards of health food. Effects of the EPS on immunity were investigated by promoted the proliferation of spleen lymph cells, delayed type hypersensitivity reaction, the HC50 value and macrophage function assay in mice. Data showed that the EPS could obviously increase the ratio of swallowed chicken red blood cell by macrophage and the HC50 value in mice. However, no significant effect was found on the delayed type hypersensitive induced by sheep red blood cell, for only the low dose of 100 mg/(kg?d) EPS promoted the proliferation of spleen lymph cells. Bifidobacterium spp. EPS can certain immunomodulating function.

As the major pathway mediating specific protein degradation in eukaryotes, ubiquitin-proteasome system (UPS) is involved in various physiological and pathological processes such as cell cycle regulation, immune response, signal transduction and DNA-repair. Deubiquitinases (DUB) maintain the balance of UPS and related physiological processes via reversibly removing ubiquitin from the covalently modified protein substrates, which have been implicated in various disease processes in case of their imbalance expression. Because DUB plays critical regulating roles in the UPS pathway, they may be also the ideal drug targets for severe and intractable human diseases, such as cancer and neurodegenerative disease. With the rapid development of proteomic technology, systematical investigation of specific substrates and interacting proteins of varied DUB via mass spectrometry approach may shed light on these DUB's biological function and regulating roles in the physiological and pathogenic states. In this review, we briefly introduce the characteristics of DUB and summarize the recent application and progresses of proteomics in DUB research.

Protein ubiquitination is one of the most important and widely exist protein post-translational modifications in eukaryotic cells, which takes the ubiquitin and ubiquitin chains as signal molecules to covalently modify other protein substrates. It plays an important roles in the control of almost all of the life processes, including gene transcription and translation, signal transduction and cell-cycle progression, besides classical 26S protesome degradation pathway. Varied modification sites in the same substrates as well as different types of ubiquitin linkages in the same modification sites contain different structural information, which conduct different signal or even determine the fate of the protein substrates in the cell. Any abnormalities in ubiquitin chain formation or its modification process may cause severe problem in maintaining the balance of intracellular environment and finally result in serious health problem of human being. In this review, we discussed the discovery, genetic characteristics and the crystal structure of the ubiquitin. We also emphasized the recent progresses of the assembly processes, structure and their biological function of ubiquitin chains. The relationship between the disregulation and related human diseases has also been discussed. These progress will shed light on the complexity of proteome, which may also provide tools in the new drug research and development processes.
