Methods The Vp1 protein was obtained by prokaryotic expression, and monoclonal antibody against this protein was prepared by hybridoma technique. ELISA and Western blot were used to identify monoclonal antibodies. Then,the monoclonal antibody was prepared in quantity by injecting hybridoma cells into the abdominal cavity of BALB/C mice, and purified by using protein G affinity chromatography. Clinical isolates of Chlamydia trachomatis were screened for the chlamydiaphage by immumofluorescence assay using the prepared monoclonal antibody.Results Purified Vp1 protein was obtained. The monoclonal antibody against Vp1 protein was gained after 3times of sub-clone and consistently identified as IgG1. Three hybridoma cell strains that stably secreted monoclonal antibody were generated. Chromosome analysis of hybridoma cells showed that the mean number of chromosome was 96, most of them were telocentric and a few were submetacentric. The titer of purified monoclonal antibody was more than 1: 12 800. Twenty clinical isolates were screened by using the monoclonal antibody and no positive results were obtained. Conclusions The monoclonal antibody against Vp1 protein of chlamydiaphage φCPG1 is successfully prepared, while no chlamydiaphage is detected by immumofluorescence assay using the prepared antibody in 20 clinical isolates of Ct.

Tibetan Herbal medicine has its own complete theory based on five sources doctrine. And the theories of "Liuwei", "Baxing" and "Shiqi Gongxiao" formed the basic core components of the property theory of Tibetan medicine. However, books and literature of Tibetan medicine have never been systematically expounded and discussed about it specially which thus will limit the further development of Tibetan medicine theory. In this thesis, we firstly introduced three basic core components of the property theory-the "Liu Wei", "Baxing", and "Shiqi Gongxiao" and their interactions as well. At the same time, the links and similarities between the theory of Tibetan medicine and Chinese medicine theory were compared. The job of the thesis done above is to lay the foundation for further systematic reveal and development of Tibetan medicine theory.

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.

Absract: Objective To report the result of annual monitoring and analysis of nasopharyngeal virus in children with respiratory tract infections in Nanxiang, Shanghai District. Methods Nasopharyngeal secretions were collected from 4389 children with acute respiratory tract infection in outpatient department from January 2007 to September 2013, 9 common respiratory viruses were analyzed by Multiplex RT-PCR, including inlfuenza virus (FLU), parainlfuenza virus (PIV), respiratory syncytical virus (RSV) , adenovirus (ADV), human bocavirus(HBOV), human coronavirus(Cov), enterovirus(EV), human metapneumovirus(HMPV), and rhinovirus(HRV). The same analysis was done in 123 asymptomatic children during the same period. Results The positive rate of detected respiratory viruses in children with respiratory tract infections in nasopharyngeal secretions were 34.8% (1526/4389), including FLU 10.3% (453/4389), RSV 7.3% (320/4389), PIV 6.2%(274/4389), ADV 3.3%(146/4389), HBOV 2.7%(118/4389), EV 2.5%(110/4389), Cov 2.4%(105/4389), HRV 1.6%(72/4389), HMPV 1.5%(67/4389);two and more combined respiratory viral infection were found in 273 cases (6.2%). The virus detection
rate between age groups was signiifcantly different (χ2=41.91, P<0.001). The school-age group had the lowest positive rate of 23.4%and the positive rates in other three groups were all higher than 35.0%. The infant group had the higher positive rate of RSV and HRV. FLU detection rate in school-age group was 13.6%. Respiratory viruses in children with asthmatic disease has high detection rate. RSV infection rate was the highest 14.8%(30/204) in the asthmatic disease group, followed by HBOV 13.8% (28/204). In nasopharyngeal secretions of 123 asymptomatic children, virus-positive detection rate of 6.5% (8/123), which showed signiifcant difference from that in respiratory virus infection group (χ2=42.60, P<0.001). Conclusions In seven consecutive years of testing, the inlfuenza virus and respiratory syncytial virus play an important role in children with respiratory tract infections in this region. The detection rate of virus showed difference between different age groups and a higher detection rate of RSV in infants with respiratory tract infections was observed. The overall detection rate of virus was decreased with the increase of age excluding the inlfuenza virus.
