Standards of commodity classes of Chinese materia medica is an important way to solve the "Lemons Problem" of traditional Chinese medicine market. Standards of commodity classes are also helpful to rebuild market mechanisms for "high price for good quality". The previous edition of commodity classes standards of Chinese materia medica was made 30 years ago. It is no longer adapted to the market demand. This article researched progress on standards of commodity classes of Chinese materia medica. It considered that biological activity is a better choice than chemical constituents for standards of commodity classes of Chinese materia medica. It is also considered that the key point to set standards of commodity classes is finding the influencing factors between "good quality" and "bad quality". The article also discussed the range of commodity classes of Chinese materia medica, and how to coordinate standards of pharmacopoeia and commodity classes. According to different demands, diversiform standards can be used in commodity classes of Chinese materia medica, but efficacy is considered the most important index of commodity standard. Decoction pieces can be included in standards of commodity classes of Chinese materia medica. The authors also formulated the standards of commodity classes of Notoginseng Radix as an example, and hope this study can make a positive and promotion effect on traditional Chinese medicine market related research.

The complex production processes and long industrial chain in traditional Chinese medicine (TCM) market result in difficulty in Chinese market microstructure research. Based on the defining the logical relationships among different concepts. This paper divides TCM market into two stages as Chinese materia medica resource market and traditional Chinese Patent Medicines market. Under this foundation, we investigated the supply capacity, approaching rules and motivation system of suppliers in TCM market, analyzed the demand situation in the perspective of demand side, and evaluated the purchasing power in terms of population profile, income, and insurance. Furthermore we also analyzed the price formation mechanism in two stages of TCM market. We hope this study can make a positive and promotion effect on TCM market related research.

As an important neurotransmitter, adenosine displays its functions by acting on the adenosine receptors. Recent studies have shown that the distribution, expression and balance among subtypes of adenosine receptors are closely related with cognitive activities, and changes of adenosine receptors play key roles in neurodegenerative disorders including Alzheimer's disease. It has been pointed out that prolonged activation of adenosine receptors by high level adenosine may lead to the disturbance of balance among adenosine receptor subtypes. This imbalance mainly performed as increased expression of A2a receptor and decreased expression of A1 receptor, and enhancement of the excitatory signals mediated by A2a receptor and weakened inhibitory signals mediated by A1 receptor. Changes of these two subtypes of adenosine receptors may lead to a lot of disorders of neurological activities which developed into dysfunction of cognition to the end. These findings imply that the potential of maintaining the balance among adenosine receptors on the treatment of AD would facilitate both the revealing of the mechanism and the cure of AD.

Objective To study the repair function of united endothelial progenitor cells (EPC)transplantation on injured liver endothelium by bone marrow transplantation (BMT) conditioning.Methods C57BL/6 mice were divided into four groups randomly: normal control group, without any treatment; irradiation alone group, administered a total body irradiation(TBI) pretreatment, without BMT; (3) BMT alone group: C57BL/6 mice were infused with bone marrow mononuclearcells (MNC) 5 × 106/only through caudal vein not more than 4 h after the same TBI pretreatment as the irradiation alone group; united transplantation group: receiving the same way as the BMT alone group, but C57BL/6 mice were infused with EPC 5 × 105/only at the same time. Two, 4, 7, 14, and 21 days after the TBI, the changes of the liver weight were observed regularly. The histopathological examination of liver was done at the 4th, 7th, 14th, and 21st day after the TBI. Results In irradiation alone group, BMT alone group and united transplantation group the liver weight began to increase significantly on the day 2 and peaked at 14th day after the TBI, and the peaks were respectively (1.65±0. 15) times (P<0. 05), (1.61 ±0.06) times (P<0.05), and (1.11 ±0.40)times (P<0. 05) of those in normal control group. At the day 14, the liver weight in irradiation alone group, BMT alone group and united transplantation group began to decrease, and on the day 21 the liver weight in united transplantation group had been completely restored to normal level, however the liver weight in irradiation alone group and BMT alone group were still significantly heavier than that in normal control group (P<0. 05). Liver histopathological examination revealed that there were obvious sinusoidal endothelial cells (SEC) injury, hepatocyte edema and severe inflammatory cell infiltration in irradiation alone group, and on the day 7 the hepatocyte edema and necrosis were significantly worse than before, and almost no alive SEC were found. On the day 14 the injury of SEC in BMT alone group was lighter than before, but on the day 21 the injury had not returned to normal. On the day 7 the injury of SEC, hepatocyte edema and necrosis were alleviated in united transplantation group as compared with irradiation alone group and BMT alone group, and on the day 14 the injury had returned to normal basically. Conclusion The transplantation conditioning could damage recipient liver endothelium and the injury would persist, and united EPC infusion could repair the injured SEC following BMT.
