OBJECTIVE:To provide references for the expanding of Chinese traditional medicine enterprises in USA market.METHODS:The management mode of the botanical preparations in the USA and the related laws and regulations were overviewed from the perspectives of dietary replenisher and drug areas.RESULTS&CONSCLUSION:For the entry of Chi?nese traditional medicine into the USA market,a realistic way of behavior for the time being is to adopt a step-by-step pol?icy,i.e.first of all,a research of the standard botanical extracts should be conducted before entering into the USA market in the status of dietary replenishers,then the clinical research application was raised after marketing in USA market for several years,eventually,new drug application was raised.

OBJECTIVE:To facilitate a better understanding of the European Union(EU)herbal drugs market for Chinese TCM enterprises and to promote the internationalization of Chinese traditional medicines.METHODS:The opportunities and challenges confronted by TCM enterprises in their expanding of their products in the EU herbal medicine market were analyzed based on the knowledge about market size,market segmentation,consumption patters and developmental tendencies of the EU herbal medicine market.RESULTS&CONCLUSIONS:There were both opportunities and challenges for the expanding of traditional Chinese medicines in the EU herbal medicine market,yet on the whole,the opportunities were more than the challenge.Chinese enterprises should strive to further expand the EU herbal medicine market.

PURPOSE To investigate the effects of all trans retinoic acid(ATRA) on the growth of gastric cancer cells and explore the mechanism relevant to enzyme.METHODS With MTT method the growth inhibition of gastric cancer cells was measured;the activity of lactate dehydrogenase(LDH),alkaline phosphatase(ALP) and ? glucuronidase(? G) was measured with metaplate;The activity of succinate dehydrogenase(SDH) was assayed with cytochemical method.RESULTS The growth of MGc80 3, but not MKN 45, was inhibited,which is dependent on the concentration of ATRA.The activity of LDH,ALP and ? G of Mgc80 3 was suppressed and the activity of SDH of Mgc80 3 was enhanced.But all the four enzymes′ activity of MKN 45 were not obviously changed except that introcelluar ? G activity was inhibited.CONCLUSIONS The sensitivity of gastric cancer cells to ATRA is different,which is closely related with the change of enzyme activity.

Objective To construct the suppression subtractive library of hemin-inducing K562 cells for identifying the cDNA genes of globin synthesis regulatory factors expressed in K562 cells induced by hemin. Methods K562 cells were cultured under different concentration of hemin, both the percentage of positive benzidine staining cells and hemoglobin content were measured, the most reasonable concentration of hemin was chosen for inducing incubation of K562 cells. The poly (A) positive RNA (mRNA) was isolated from the hemin-induced K562 cells (tester) and non-induced K562 cells (driver) respectively, and double-strand cDNA molecules were synthesized by reverse transcription. After two times subtractive hybridization followed by two times polymerase chain reaction (PCR) amplification, the forward subtracted PCR products were ligated with pGEM T-Easy vector and the subtracted cDNA library was constructed. The library clones were selected by blue-white screening. The plasmid DNAs of the single positive colony were purified and digested by EcoRⅠ, and the inserts in plasmid were amplified by PCR. Results The maximum of positive benzidine staining cells percentage and hemoglobin content of K562 cells were obtained in 50?mol/L of hemin inducing condition. The suppression subtractive library of hemin-inducing K562 cells was constructed after K562 cells were induced by 50?mol/L of hemin. The library identification showed that the positive clones contain inserts in different length respectively. Conclusions The suppression subtracted cDNA library of hemin-inducing K562 cells were successfully constructed. This subtracted cDNA library combined with bioinformatics analysis can be used to explore structures and functions of hemin-inducing expression genes in K562 cells.
