The fermentation broth of one actinomycete strain ACMA006 strongly inhibited growth of many tumor cells and some microorganisms, but its cytotoxicity to human normal cells were weak. Strain ACMA006 grow well on most tested media, producing exuberant vegetative hyphae and aerial hyphae. Its optimization temperature is 28?C. Phyloge-netic analysis based on 16S rDNA sequence showed that strain ACMA006 was closely related to one of the genus Streptomycetes (S.cavourensis subsp. washingtonensis) with 16S rDNA sequence similarity values of 100%, but had many differences in other features including its morphology, physiological and biochemical characteristics. The pre-liminary study supported the view that the strain ACMA006 represented a new strain of the S.cavourensis subsp. wash-ingtonensis.

Objective To establish an approach of polymerase chain reaction-sequence special primers(PCR-SSP) to perform polymorphism analysis for multiple genes simultaneously,in order to be used in clinical analysis.Methods The optimized PCR-SSP approach was used to analyze the polymorphism of the following genes:mutation of-308A/G and-238G/A in tumor necrosis factor-?((TNF-?)),-174G/C in interleukin-6(IL-6).Results Polymorphism analysis of multiple genes and many clinical samples could be simultaneously performed with one PCR program,showing clear genotype,quick and accurate genotype.Conclusion The optimized(PCR-SSP) is suitable for polymorphism analysis of the large-sample polygenic mononcleeotide point mutation,and it can be widely applied in clinical test for low cost,quickness and accuracy.

In this study, prescriptions were collected to establish a database based on the traditional Chinese medicine inheritance support system (TCMISS). Such data-mining methods as software's statistical statement module, data analysis module and apriori algorithm were used to analyze the frequency of single drug, the frequency of drug combination, the association rules and the core drug combinations of ostreae concha-containing prescriptions. The results showed that Ostreae Concha-containing prescriptions were frequently used to treat insomnia, vertigo, stomach-ache and other syndromes. The frequently used drugs included Ossis Mastodi Fossilia, Parched Ziziphi Spinosae Semen, Polygoni Multiflori Caulis, Salviae Miltiorrhizae Radix and Paeoniae Rubra Radix. The frequently used drug combinations included "Ostreae Concha and Ossis Mastodi Fossilia", "Ostreae Concha and Parched Ziziphi Spinosae Semen", and "Ostreae Concha and Polygoni Multiflori Caulis". The drug association rules with the confidence coefficient of more than 0. 95 included "Ossis Mastodi Fossilia-->Ostreae Concha", "Cocos Poria-Ossis Mastodi Fossilia-Ostreae Concha", "Ossis Mastodi Fossilia-Parched Ziziphi Spinosae Semen-->Ostreae Concha", and "Salviae Miltiorrhizae Radix-Ossis Mastodi Fossilia--Ostreae Concha".

Analyzed the prescriptions for phlegm retention syndrome that built by Ma Peizhi by the association rules and clustering algorithm, the frequency of drug usage and the relationship between drugs could be get. And from that we could conclude the experiences for phlegm retention syndrome of Ma Peizhi of menghe medical genre. The results of the analysis were that 18 core combinations were dig out, such as Citri Exocarpium Rubrum-Eriobotryae Folium-Citri Reticulatae Pericarpium. And there were 9 new prescriptions were found out such as Aurantii Fructus-Citri Exocarpium Rubium-Eriobotryae Folium-Citri Reticulatae Pericarpium. The results of the analysis were proved that Ma Peizhi of Menghe Medical Genre was good at curing phlegm retention syndrome by using the traditional Chinese medicine of mild and light, such as the medicines of mild tonification, and clearing damp and promoting diuresis.

Based on the data mining methods of association rules and clustering algorithm, the 188 prescriptions for cough that built by Yan Zhenghua were collected and analyzed to get the frequency of drug usage and the relationship between drugs. From which we could conclude the experiences of Yan Zhenghua for the treatment of cough. The results of the analysis were that 20 core combinations were dig out, such as Bambusae Caulis in Taenias-Almond-Sactmarsh Aster. And there were 10 new prescriptions were found out, such as Sactmarsh Aster-Scutellariae Radix-Album Viscum-Bambusae Caulis in Taenian-Eriobotryae Folium. The results of the analysis were proved that Yan Zhenghua was good at curing cough by using the traditional Chinese medicine that can dispel wind and heat from the body, and remove heat from the lung to relieve cough.

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.

OBJECTIVETo introduce the framework of evidence-based practice with a case of castration-resistant prostate cancer (CRPC) as an example.

METHODSA clinical question was formulated according the clinical scenario. A systematic search was conducted for the published literature in the databases of PubMed, EMBASE, Cochrane Library, Clinical Trial Registries, and Web of Knowledge up to Dec 2014. The identified literature was reviewed for quality appraisal before the evidence was applied to clinical practice.

RESULTSThe treatment was effective and the patient achieved disease remission.

CONCLUSIONEvidence-based practice should be integrated with clinical scenario, current evidence, and patients' willingness, and follow a systematic framework.

Heterotrimeric G proteins are classes of signal-transducing proteins that bind to guanine nucleotides and possess GTP hydrolase activity. G proteins are composed of three subunits α, β, and γ, and are considered as the "molecular switch" in the GPCR signaling pathway. The abnormal activation of G protein is strongly related to diseases such as uveal melanoma, asthma, et al., making directly targeting G protein as an promising strategy for combating diseases. In this review, the classification and physiological functions of G protein are briefly described, and the research progress of G proteins in diseases, G protein modulators are reviewed.
