During the washing process of coarse bear gall powder extracts, it is necessary to adjust the amount of ethyl acetate according to the properties of raw materials, which aims to improving the yield and purity of the final product. In the research, using NIR spectra to reflect the comprehensive properties of coarse bear gall powder extracts, the process is optimized in a flexible way. Forty batches experiments are designed according to the weight ratio of ethyl acetate and coarse extracts of bear gall powder. The NIR spectra of the coarse extracts of bear gall powder are collected and processed using principal component analysis (PCA) method. The first 8 principal components combined with the amount of the ethyl acetate are used as the input variables, and calibration models are established to predict the yield and purity of the final product 30 batches are used as calibration set, which is used to establish the models, and other 10 batches are used as validation set, which is used for the performance appraisal of the established models. The correlation coefficients of the calibration, inner cross-validation and external validation for the purity model are 0.902, 0.896 and 0.883, respectively, and the RMSEC, RMSECV and RMSEP are 1.22%, 1.48% and 1.59%, respectively. The correlation coefficients of the calibration, inner cross-validation and external validation for the yield model are 0.921, 0.859 and 0.916, respectively, and the RMSEC, RMSECV and RMSEP are 1.39%, 1.65% and 1.53% respectively. This work demonstrated that NIR spectra combined with technology parameter could be used to predict the yield and purity of the final product. Using the established models, the most appropriate amount of the ethyl acetate can be determined according to the properties of the coarse bear gall powder extracts, and the yield and purity of the final product can be improved.

OBJECTIVETo study the relationship between the structure and functional activity of hTNF alpha.

METHODSFour hTNF alpha mutants were constructed, different binding structures and gene responses related with these mutants were studied by the methods of immunoprecipitation and mRNA differential display.

RESULTSThe specific activities and LD50 of the different hTNF alpha mutants indicated their different bioactivities. It was shown that the hTNF alpha mutants had the relative binding affinities to the wild types. The mRNA differential display assay proved that the hTNF alpha mutants stimulated different gene responses.

CONCLUSIONThese results suggest that the specific anti-tumor activities of hTNF alpha mutants are accomplished by inducing different or same gene response at different quantities after its binding to specific receptor.

The high price of the reference substances is an obstacle for the HPLC analysis of Lonicerae Japonicae Flos. To solve this problem, a new method based on the standard reference extract (SRE) was proposed. In this study, the extract of Lonicerae Japonicae Flos was calibrated, and the long-term stability was investigated. Different concentration solutions of SRE were prepared for establishment of the calibration profiles, and 6 organic acids were determined. T-test was used for the comparison of the determination results via reference substances and SRE, and the results demonstrated that there is no significant difference between the two methods. The presented method can be used for the quality control of Lonicerae Japonicae Flos, and will also offer reference to resolve similar problems.

OBJECTIVETo evaluate the feasibility and efficacy of cytocine deaminase-thymidine kinase (CD-TK) fusion double suicide gene therapy using adenovirus mediated CD-TK gene and green fluorescent rotein (GFP) gene combined with ganciclovir(GCV) or 5-flourocytosine(5-FC) in a murine subcutaneous bladder carcinoma model.

METHODSA replication defective adenovirus vector containing CD-TK gene was used. Subcutaneous tumors were established in syngenic C57BL/6 female mice with 1 x 10(6) Mb49 cells. Intratumoral injection of AdCD-TK (1.58 x 10(8) PFU, qd x days) in combination with GCV (40 mg.kg(-1).d(-1), ip, qd x 10 days) or 5-FC (400 mg.kg(-1).d(-1), ip, qd x 10 days) was administered in vivo for the determination of treatment efficacy in separate controlled experiments.

RESULTSIn vivo experiments demonstrated that the mean volume of tumor in the group of AdCD-TK/GCV(326.58+/-109.56 mm(3)), AdCD-TK/5-FC (235.33+/-62.94 mm(3)) and AdCD-TK/(GCV+5-FC) (23.58+/-6.78 mm(3)) was reduced significantly compared with that of control group (993.51+/-158.32 mm(3)) (P=0.00), the mean volume of tumor in the group of AdCD-TK/(GCV+5-FC) was significantly less than that in the group of AdCD-TK/GCV or AdCD-TK/5-FC (P=0.04). Tumor necrosis was revealed by histomorphology compared with control animals.

CONCLUSIONSAdenovirus mediated CD-TK double suicide gene combining with GCV or 5-FC could provide an effective therapy in an experimental murine bladder carcinoma by significantly inhibiting tumor growth. The treatment efficacy of AdCD-TK combining GCV and 5-FC was superior to that of AdCD-TK combining GCV or AdCD-TK combining 5-FC.
