90% in 20 min and more higher than the control tablets or capsule. CONCLUSION: The optimum formulation suits to slightly soluble drugs with different o/w distribution coefficient.It can provide reference for application of the SMEDDS the practical cases.

AIM:To establish the quality standard for Pheretima Dispensing Granules.METHODS:Pheretima Dispensing Granules were identified by TLC.The content of hypoxanthine in Pheretima Dispensing Granules was determined by HPLC,and succinic acid by high performance capillary electrophoresis HPCE.RESULTS:Spots obtained from the test solutions had the same color as amino acid reference solution,Pheretima reference substance and the blank solution had no interference.The contents of hypoxanthine were in the range of 1.6 mg/bag-3.3 mg/bag and succinic acid 23.58 mg/bag-35.38 mg/bag in Pheretima Dispensing Granules,respectively.CONCLUSION:The methods of identification and quantification were accurate,realizable and reproducible.It can be used effectively for the quality control for Dispensing Granules.

Objective:To show whether the Fas Ligand gene induces mast cells apoptosis.Methods:RT-PCR was used to amplify the gene of rat Fas ligand extracelluar domain and transmembrane domain and cloned it into eukaryotic expression plasmid pcDNA3.1.Transcent transfect RBL-2H3,the expression of Fas ligand RBL-2H3 was detected by RT-PCR、Western blot.The Annexin V FCM was used to detect the RBL-2H3 apoptosis after the transfection of Fas Ligand.Results:It is successful to obtain the gene of rat Fas Ligand extracellular domain and transmembrane segment,cloning it into pcDNA3.1,FasL was expressed on the surface of RBL-2H3 and it's supernatant after the transfection of pcDNA3.1/FasL.The cell start to be apoptosis.Conclusion:Our study reveals that Fas Ligand gene transfection in RBL-2H3 can effectively induced apoptosis.It is a promising strategy for Fas Ligand to be used in the therapy of allergic disease.

Objective A state quo survey of laboratory animal resource in Guangdong province is performed to provide reference data for government management decision-making and market assessment of laboratory animals. Methods We used questionnaires focusing on the laboratory animal facilities with authorization by Guangdong Province Government, which mainly included the production and use of laboratory animals,the qualification of employees and the facilities space. Results The total production and use of laboratory animals(except for the eggs)had been increasing in the last four years. 1.57 million laboratory animals were produced and 0.754 million laboratory animals were used in 2016. There were 2352 employees,roughly the same as in 2015. The facilities space for breeding was 121008 m2,and for animal experiment was 73470 m2,which were rising in the past three years. Conclusions In order to reinforce the industry development of laboratory animals in Guangdong province,some suggestions were given in our study,such as facilitating the application of superiority resource including non-human primate and aquatic laboratory animals,supporting the standardization production of several scarce mice and rats, improving relevant employees' overall level and constructing laboratory animal facilities sharing platform.
