OBJECTIVETo establish a characterization system of traditional Chinese medicinal properties in line with modern scientific cognition regularity, in order to reveal properties of traditional Chinese medicines distributed along liver meridian and relations of effects of medicinal properties.

METHODBy collecting data about traditional Chinese medicinal properties recorded in the Pharmacopoeia of the People's Republic of China (2005 Edition), literature and data about pharmacological effects of traditional Chinese medicines recorded in the Chinese Materia Medica, by using the method of association rules, the authors dug pharmacological effect rules corresponds to relevant medicinal property combinations, with the medicinal property combination of traditional Chinese medicines distributed along liver meridian as the target.

RESULTIt was found that either obvious different pharmacological effects or identical pharmacological characteristics existed in traditional Chinese medicines distributed along liver meridian.

CONCLUSIONWith the aim to explore the correlations between traditional Chinese medicine medicinal properties and pharmacological effects, the authors linked the traditional Chinese medicine theory with modern research achievements, in order to provide the ideas and methods for interpreting mechanisms of medicinal properties.

Objective To construct cDNA entry library and cDNA expression library of Armillifer agkistrodontis (A.) nymphs and make a preliminary immunoscreening for the cDNA expression library.Methods The nymphs were collected from the Kunming mice infected experimentally with A.agkistrodontis eggs and the total RNA were extracted from the nymphs using TRIzol Reagent.After purifying the mRNA,the synthesized cDNAs were cloned into the donor vector pDONR222 by BP reaction of Gateway technology and the recombinants were transformed into the DH10B cells by electroporation,the cDNA entry library was obtained.Next,the expression vector pDEST17 was ligated with entry clones by LR reaction,and the recombinants were transformed into the BL21 (DE3) cells.Hence,the cDNA expression library was constructed.Then,the expression library was immunoscreened with the mixed sera of mice infected with A.agkistrodontis,and the insertions of positive clones were sequenced.After that,the open reading frame(ORF) of positive slone sequence,the homology of the screened genes and their encoded proteins were analyzed by Finder and BLAST (basic local alignment search tool) program of National Center of Biotechnology Information(NCBI),and the discovered new genes were submitted into the GenBank.Besides,the physico-chemical properties,secondary structure and B cell epitopes of encoded proteins were also analyzed by bioinformatics software.Results The average titer and total clones of the cDNA entry library were 1.45 × 105 CFU/ml(colony-forming unit,CFU) and 1.74 × 106 CFU,respectively,and the range of fragment length of the inserted cDNA was between 0.2-4.0 kb,with an average of 1.4 kb.The total clones of cDNA expression library were 1.00 × 105 CFU,and the fragment length of the inserted cDNA was between 0.3-2.2 kb,with an average of 1.0 kb.Five positive clones,coded S1,S5,A1,D1 and F1,respectively,were obtained through preliminary immunoscreening.The sequence and homology of the five positive clones were sequenced and analyzed by BLAST program.No significant similarities were found in pentastomida species,which meant that they were all novel genes of A.agkistrodontis.The gene sequences were submitted to GenBank,with the accession number from JQ180451 to JQ180455.Also,results obtained by bioinformatics software showed that the predictive encoding proteins were all potential to be valuable recombinant diagnostic antigens.Conclusions The cDNA library of A.agkistrodontis nymphs is successfully constructed,and five new genes of A.agkistrodontis are discovered.The establishment of cDNA library and the discovery of the new genes will lay a foundation for further studying the gene functions and screening the immunodiagnostic antigens.

Objective The aim of our study is to establish and characterize the animal model for au- toimmune myositis.Methods Fifty male SD rats were randomly divided into 2 groups:model group(n=40) and control group(n=10).The model group rats were immunized with muscle homogenate every week for 5 weeks and received an injection of 2?g pertussis toxin at the first and second week.As controls,10 SD rats were injected with an equal volume of normal saline.Tissue specimens from limb skeletal muscles were ob- tained at 1,2,3,4,5 weeks after injection.At the same time,the blood samples were collected,and the level of CPK was measured.Results The model group had significantly elevated serum CPK levels.There were multiple inflammatory lesions in the skeletal muscles.Local degeneration and necrosis of muscle fibers with disappeared transverse striation,mononuelear cell infiltration in the interstitial could be observed.The patho- logic grade was mainly 2a.The infiltrating mononuclear cells were predominantly CD8~+T cells that mainly lo- cated in the endnmysium.MHC classⅠantigen expression on muscle fiber membranes in the model group was upregulated.Conclusion The experimental autoimmune myositis induced by syngeneic skeletal muscle ho- mogenate in SD rat is pathologically similar to human myositis.It can be used as a good model for human myositis and provides the basis for the etiopathology and therapeutical studies.

Objective To compare the efficacy of concurrent chemoradiotherapy versus radiotherapy alone for T3-4 N0-1 M0 and T14 N2-3 M0 nasopharyngeal carcinoma (NPC) after induction chemotherapy.Methods From 2002 to 2005,400 patients with stage Ⅲ and Ⅳa NPC were randomly divided into 2 groups :induction chemotherapy followed by concurrent chemoradiotherapy group (IC/CCRT,201 patients),and induction chemotherapy followed by radiotherapy alone group (IC/RT, 199 patients).Subgroup analysis was conducted for 197 patients with stage T3-4N0-1M0 NPC and 203 with stage T1-4N2-3M0 NPC.Results The follow-up rate were 96.2%, with a median followg-up time of 3.9 years.For T3-4N0-1 M0 NPC patients in IC/CCRT group (104 patients) and IC/RT group (93 patients), the 3-year overall survival, disease-free survival, locoregional recurrence-free survival and distant metastasis-free survival rates were 84.0% and 85.9% (χ2=0.08,P =0.780) ,77.0% and 72.0% (χ2=0.44,P =0.510) ,89.5% and 92.3% (χ2=0.65 ,P = 0.420), and 84.9% and 77.0% (χ2= 1.59, P = 0.210), respectively; For T1-4 N2-3 M0 NPC patients in IC/CCRT group (97 patients) and IC/RT group (106 patients), the corresponding rates were 67.4% and 82.2% (χ2=3.48,P=0.060), 61.5% and 68.0% (χ2= 1.86,P=0.170), 86.2% and 87.0% (χ2=0.57 ,P =0.450) and 66.2% and 75.6% (χ2=2.07 ,P =0.150), respectively.Acute sideeffects were similar except more leucocytopenia in IC/CCRT group than IC/RT group.Conclusions Compared with IC/RT, IC/CCRT dose not improve the overall survival in patients with T3-4N0-1 M0 and T1-4 N2-3 M0 NPC.

Questionnaire survey was conducted among thirty traditional Chinese pharmaceutical companies nationwide. We studied the following factors and how they impose the significance on the culture of big brands, namely, the policies, the access to market, the specialty of the product, the foundation of research, the market, the salesmanship, the resource insurance of product and the security. And these could be referred when the enterprises cultivate the big brands. The findings show that interviewees and different firms hold various opinions on the factors of culture of the big brands. The policies and the access to market always attract the most attention for the enterprises, and whether the product is classified into the catalogue of health insurance or into the basic medicinal directory plays a pivotal role in the development of big brand. The uniqueness of the product can be regarded as a natural advantage, the construction of team of academic experts is more and more emphasized on the development of the product, and the security of the product deserves increasing attention.
