J6-1 cell line is the first leukemic cell line established in China. It is a multi-clone cell line infected with both EBV and HHV-6. Many cytokines, receptors and other genes were cloned from J6-1 cell line since its establishment 30 years ago. Valuable information on leukemic characteristics and functions were obtained from the studies on this cell line, which could be categorized into several research subjects. These achievements implied the unique research value of multi-clone cell lines. This comment focuses attention on research advance of the J6-1 leukemic cell line in 30 years, including heterogeneity and multi-cloning of J6-1 cells, survival mechanism of J6-1 cell populations, abnormal intercellalar communication of J6-1 cells with its significance and inspiration from J6-1 cell line.

The prescriptions containing pericarpium citri reticulatae that built by Professor. Yan were collected to build a database based on traditional Chinese medicine (TCM) inheritance assist system. After analyzed by data mining, such as apriori algorithm, the frequency of single medicine, the frequency of drug combination, the association rules between drugs and core drug combinations can be get from the database. Through the analysis of 1 027 prescriptions with pericarpium citri reticulatae, these prescriptions were commonly used to treat stomach aches, cough and other syndromes. The most frequency drug combinations were "Citri Reticulatae Pericarpium-Poria", "Paeoniae Radix Rubra-Citri Reticulatae Pericarpium" and so on. The drug association rules that the confidence was 1 were "Glycyrrhizae Radix ex Rhizoma --> Citri Reticulatae Pericarpium", "Paeoniae Alba Radix-Cyperi Rhizoma --> Citri Reticulatae Pericarpium", "Poria --> Citri Reticulatae Pericarpium", and so on. The drugs in the prescriptions containing pericarpium citri reticulatae that built by Professor Yan mostly had the effects of regulating the flow of Qi and invigorate blood circulation, which reflected the clearly thought when making prescriptions.

Relapse, which puzzled several generations of hematologists, is the bottle-neck of radical treatment for leukemias. The progress of Human Microbiome Project at the beginning of 21st century suggested that human body was a super-organism constituted by the core of human cells and symbiotic microorganisms. The elucidation and characterization of endogenous retrovirus and prion protein suggested the possible effects of co-evolutional microorganisms on human health. Recently, the elucidation of the roles of tunneling nanotubes in intercellular communication and transportation suggested a novel way for cellular communication and transport of oncogenic materials. The role and significance of in vivo cell fusion have been studied in more detail. On the other hand, donor cell leukemia was reported. All of these approaches provide novel insights for studying the mechanism of leukemia relapse. Based on previous work, the authors suggest the hypothesis: there are two possible mechanisms for the relapse of leukemias: the minimal residual disease (MRD) and intercellular transportation of oncogenic materials.

Aim To evaluate the effects of pantoprazole on various experimental acute ulcer inrats and mice. Methods The model of a gastric ulcer of rats or mice was caused bystree- induced ulcer and ligatel pylurus-induced ulcer. Results & Conclusions At adose of 5, 10, 20 mg? kg-1 of Pantoprazole can markedly decrease the ulcer index ofstree-induced ulcer. Pantoprazole(4, 8, 16 mg? kg -1 ) significantly decrease the areaof ligated pylorus-induced gastric ulcer. It was also found that pantoprazole caninhibit the output of basic gastric acid.

Sanjie Zhentong capsules were scanned by using a near infrared spectra probe with different drug mass fraction and the spectral information of capsule shells and contents in it were obtained. Then partial least squares (PLS) models were developed for the prediction of mass fraction of Fritillariae Thunbergii Bulbus and Resine draconis in Sanjie Zhentong capsules. The correlation coefficient (r9c)) and root mean standard error( RMSEC) of 0.949 5, 0.958 2 and 4.742 4, 4.135 7. The models obtained correlation coefficient (r(v)) of 0.919 2, 0.936 7 and root mean square error (RMSECV) of 6.158 9, 5.037 3 respectively in the training set. The paired T test analysis of statistics showed that there were no significant difference between predictive values and measure values. The established models reflected a strong prediction performance and can meet the needs of the production.

OBJECTIVETo investigate the immunological activity of Streptomyces polysaccharide (SMP) on normal and immunosuppressed mice.

METHODSThe effect of SMP on the proliferating activity of normal mouse splenocytes was tested in the mixed lymphocyte culture, and the changes of peripheral blood T lymphocytes were evaluated with acid a-naphthyl acetate esterase (ANAE) method. The ratio of Lyt2+ and L3T4+ T cell subsets was measured by flow cytometry.

RESULTSSMP stimulated obvious proliferation of mixed lymphocytes, showed protective effects on T lymphocyte and increased the ratio of Lyt2+ and L3T4+ cell subsets to nearly normal level in immunosuppressed mice.

CONCLUSIONSSMP can regulate the immune function in mice.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.
