In this paper, optimization of the conditions of microwave technique in extraction process of Guizhi Fuling capsule in the condition of a pilot scale was carried out. First of all, through the single factor experiment investigation of various factors, the overall impact tendency and range of each factor were determined. Secondly, L9 (3(4)) orthogonal test optimization was used, and the contents of gallic acid in liquid, paeoniflorin, benzoic acid, cinnamic acid, benzoyl paeoniflorin, amygdalin of the liquid medicine were detected. The extraction rate and comprehensive evaluation were calculated with the extraction effect, as the judgment basis. Theoptimum extraction process of Guizhi Fuling capsule by microwave technology was as follows: the ratio of liquid to solid was 6: 1 added to drinking water, the microwave power was 6 kW, extraction time was 20 min for 3 times. The process of the three batch of amplification through verification, the results are stable, and compared with conventional water extraction has the advantages of energy saving, time saving, high efficiency advantages. The above results show the optimum extracting technology of high efficiency, stable and feasible.

Objective Through detecting the expression of erbB-2 and erbB-3 of epithelial growth factor receptor family in clinical specimens of salivary adenoid cystic carcinoma, to explore the role of erbB-2 and erbB-3 in the carcinogenesis and development of salivary adenoid cystic carcinoma. Methods Thirty-four specimens of adenoid cystic carcinoma were tested with immunohistochemical assay. Then the relationship between the expressions of erbB-2, erbB-3 and the gender, age of patients, TNM staging, tumor size and nerve invasion were analyzed.Results The positive expression ratios of erbB-2 and erbB-3 were 64. 7% and 32.4% respectively. And 29.4% of tumors were positively stained both by erbB-2 and erbB-3. The expression of erbB-3 was significantly correlated with TNM staging of tumors (P = 0. 026). The correlationship between the expressions of erbB-2 and erbB-3 was also found. Conclusions erbB-3 and erbB-2 may play important roles in the carcinogenesis and development of salivary adenoid cystic carcinoma. The positive expression of erbB-3 was associated with the biological behavior of tumors and prognosis of patients, and might become one of markers to evaluate the prognosis of patients.

Objective To construct the recombinant plasmid pYES6-S and express and purify spike protein of severe acute respiratory syndrome(SANS)coronavirus in Saccharomyces cerevisiae. Methods DNA fragments of SANS coronavirus were obtained by reverse transeription.Four over- lapped fragments of spike protein genes were amplified by polymerase chain reaction(PCR)and ligated into an integral spike protein gene by restriction enzyme digestion.The spike protein gene recombined with pYES6 and cloned into E.coll.The recombinant plasmid pYES6-S was induced and expressed in Saccharomyces cerevisiae(INVScl)by galactose.Results The recombinant plasmid pYES6-S was confirmed that inserted fragment was right in length,direction and base matching by restriction enzyme digestion and sequencing.The purified protein encoded by the whole spike protein gene was about Mr 110?10~3 identified by electrophoresis.Conclusion The whole spike protein gene of SARS coronavirus is cloned into E.coli and the protein is expressed in Saccharomyces cerevisiae successful ly.which can be helpful in SARS vaccine research.

The teaching status of Molecular Pharmacognosy in 28 institutions in China was investigated by questionnaire and the survey data was analyzed by SPSS. Research contents included course beginning years, majors, class hours, characteristics of the course, teaching ways, the theory and practice contents, evaluation modes, selection of teaching material, teaching achievements, teachers and so on for undergraduates and graduates. Research results showed that with 20 years' development, Molecular Pharmacognosy had been offered for both undergraduate and graduate students in at least 20 colleges and universities and Molecular Pharmacognosy education in China showed good development momentum. At the same time, to promote the development of Molecular Pharmacognosy further, investment for it should be increased and practical teaching condition should be improved.

OBJECTIVETo know the antibiotic resistance and molecular characteristics of Listeria monocytogenes in Shandong province and to study the relationship between antibiotic resistance phenotypes and genome types.
METHODSFrom 2009 to 2010, a total of 80 Listeria monocytogenes isolates were collected from raw meat, cooked meat, aquatic products and other foods in 6 cities of Shandong province. The antibiotic susceptibility was measured by broth microdilution method, PFGE was performed for molecular typing and the relationship between antimicrobial resistance and PFGE patterns was analyzed.
RESULTS16.25% (13/80) of the isolates were drug-resistant. Imipenem resistance was the most prevalent (12.50%, 10/80), followed by tetracycline and doxycycline (3.75%, 3/80 and 2.50%, 2/80). A total of the 80 isolates were subtyped into 9 antibiotic resistance patterns and 34 PFGE types which were largely dominated by the type 17 and 29. Antibiotic resistance pattern A corresponded to 79.41% (27/34) of PFGE types.
CONCLUSIONThe antibiotic resistance of Listeria monocytogenes in Shandong province is serious from 2009 to 2010 and there is no correlation between PFGE types and antibiotic resistance patterns.

Taking guizhi fuling capsule (GZFL) for instance, a new method about reference Chinese medicine preparation which was used as standard substance for the quality evaluation of complex Chinese medicine preparation by the fingerprint of reference preparation instead of standard fingerprint was proposed. It could eliminate the errors from different instruments, chromatographic columns and solve the problem of similarity matching in the absence of standard fingerprint. The qualification of reference GZFL was evaluated according to the quality control method of GZFL from Chinese Pharmacopoeia. Then multiple batches of GZFL were estimated, taking fingerprint of reference preparation and standard fingerprint as references, respectively, at different instruments and chromatographic columns. Finally, the packaging and expiration date for reference GZFL were confirmed according to the results of stability investigation. The results indicated that the fingerprint of reference GZFL could be used to assess the quality of GZFL better than standard fingerprint. The data of accelerated stability and long-term stability test demonstrated that reference GZFL was stable in the conditions of double blister package. Therefore, reference GZFL can be used as standard substance in quality control of GZFL.
