MAPKKK (MEKK1 or ASK1)/MAPKK (SEK1 or MKK7)/JNK signal cascade is an important pathway which mediates apoptosis. MAPK phosphotase can deactivate JNK by dephosphorylation of JNK.The interaction between JNK and c-Jun can also be negatively regulated by NO through S-nitrosylation. SGK1 or Akt can result in deactivation of SEK1 through its phosphorylation at the Ser78 site.The c-FLIPL can block this cascade through binding with MKK7.GST Mu1-1 interferes and suppresses MEKK1-mediated apoptosis. GST Pi 1-1 and TRX have a dose-dependent inhibitory effect on ASK1 through forming protein complex. The deactivation of JNK can enhance drug resistance of tumor cells and counteract the injury from a wide variety of stimulus. Here,how these proteins induce deactivation of the pathway and mediate anti-apoptosis has been discussed.

The new drug of Chinese herbal prescription, which is the best carrier for the syndrome differentiation and treatment of Chinese medicine and is the main form of the new drug research and development, plays a very important role in the new drug research and development. Although there are many sources of the prescriptions, whether it can become a new drug, the necessity, rationality and science of the prescriptions are the key to develop the new drug. In this article, aiming at the key issues in prescriptions design, the source, classification, composition design of new drug of Chinese herbal prescriptions are discussed, and provide a useful reference for research and development of new drugs.

Objective:To culture canine dental pulp stem cells(cDPSCs)in vitro.Methods:Canine pulp cells were isolated and cultured by enzyme digestion and explanted tissue culture respectively.Cell morphology was observed under phase-contrast micro-scope.The clone forming unit(CFU)of the cells was examined by plate clone formation assay.Cell markers and protein-expression were examined by flow cytometry(FC)and immunofluorescence.Odontogenic and adipogenic potential were evaluated by alizarin red staining and oil red O staining.Results:Short spindle fibroblast-like and steadily growing cells were obtained by both methods.The clone assay showed that CFU was 1 5.1 7% ±2.79%.FC observasion showed that the CD90,STRO-1 and CD24 positive cells were 24.43% ±7.1 0%,20.67% ±1 .42% and 2.03% ±0.06% respectively,but CD34 was negative.Immunofluorescence analysis showed positive expression of Nestin,Vimentin,weak expression of ALP and negative expression of DSP of the cells.Differentiation ex-periment confirmed the odontogenic and adipogenic differentiation potential of the cells.Conclusion:cDPSCs can be cultured in vitro.

The index components contents of different time and different stubbles in honeysuckle were measured by HPLC, and were analysis by using the method of SPSS. Results showed that the content of index ingredients of different time had differences, and firstly decreased, then increased with time. The content of index ingredients of different stubbles had significantly differences, and firstly decreased, then increased with time. The chlorogenic acid contents were 2.059%-3.593%. The luteolosid contents were 0.110%-0.171%. Results indicated that the best picking buds time is before seven o'clock in the morning and evening at before and after seven o'clock, the index component content is higher. Picking buds in spring and at autumn index component content is higher; Picking buds in summer index component content is low. The experiment provides theoretical support for quality control in the whole process of the honeysuckle harvested and comprehensive utilization of honeysuckle.

Biotechnology supremacy is a newly-advanced power theory. It is a superior dominance of military biotechnological application based on the microcosm of life structure within a certain period of time. The advancement of biotechnology supremacy and modern biotechnology has created the concept of bio-micro-frontier, which involves information and defense resources of all living ultra-micro-organisms with national and regional characteristics. Being feasible both in theory and practice, the implementation of bio-micro-frontier system is strategically important. This article explores the implementation of bio-micro-frontier in terms of strategy and tactics, which will add a unique dimension to future military transformation and active defense.
