Objective To investigate the expression of aquaporin-5(AQP5) in lipo-polysaccharide(LPS)-cigarette smoking inducible SD rats,and the effect of ambroxol chloride(AMB)on its expression. Methods Twenty-one SD rats were randomly divided into three groups: AMB intervention group,model group(LPS-cigarette smoking induction group) and control group.TNF-? was determined from lung homogenate supernatant,bronchial alveolar lavage fluid(BALF) and serum by ELISA.The semi-quantitation of AQP5 transcription and expression were measured by in situ hybridization and immunohistochemistry,respectively. Results TNF-? from lung homogenate supernatant and BALF in model group was more than AMB intervention group and control group(P

Objective To express recombinant Vp1 protein of chlamydiaphage φCPG1, prepare monoclonal antibody against Vp1 protein and utilize it to screen clinical isolates of Chlamydia trachomatis. 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.

Natural products are valuable resources for discovering new drugs. So far, screening bioactive compounds from organism extracts is still an important and challenging task. Traditional biometric guided method involves repeated fractionation steps and bioactivity tests, which are time-consuming, labor-consuming, and inefficient. Ligand fishing is a bioanalysis method for screening ligands from complex organism extracts based on intermolecular affinity interactions. It has the characteristics of strong specificity, high efficiency, and less requirement for sample pretreatment. In this review, we summarize the classification of ligand fishing strategy and its application in enzyme inhibitors screening. Finally, the development prospects of this technology are forecasted.

According to Chinese medicine, the atlantoaxial joint is a composite joint composed of tendons and bones, and the stability of the joint depends on the 'tendon-bone balance' involving tendons, ligaments, atlas and axis. Multiple causes of 'tendon off-position, joint subluxation' will lead to joint 'tendon-bone imbalance', which will evolve into atlantoaxial subluxation (AAS), endangering human health. Chinese therapeutic massage (tuina) is a very effective treatment for AAS in adults, but conventional manipulations are prone to ineffectiveness or accidents due to neglect of the causal relationship of the 'tendon-bone imbalance' and inappropriate manipulations. Compared with conventional manipulations, the rational choice of modified manipulations under the guidance of 'tendon-bone balance' theory is more effective and less risky, and more worthy of clinical promotion. From the 'tendon-bone balance' theory, we considered the shortcomings of conventional manipulations, and introduced several modified manipulations that have their own strengths in 'tendon smoothing' and 'bone setting', in order to provide new ideas for treatment of AAS in adults.
