Chinese Journal of Nosocomiology 1994;0(01):-
OBJECTIVE To investigate the major pathogens and their antibiotics resistance in surgery wards in Fuwai Cardiovascular Hospital.METHODS The pathogens were classified and their antibiotics resistance was analyzed.RESULTS The pathogens mainly consisted of Gram-negative bacilli,which were sensitive to cefoperazone/sulbactam,pipercillin/tazobactam and amikacin with the sensitive rate of 62.7-97.6%.All Gram negative bacilli were sensitive to imipenem except Pseudomonas aeruginosa,with the sensitive rate of 95.2%~100%.In the Gram-positive bacteria,the susceptibility rates of Enterococcus faecium were lower than E.faecalis.Coagulase negative Staphylococcus and Staphylococcus aureus were mainly resistance to oxacillin and most other antibiotics,all Gram positive bacteria were sensitive to vancomycin.CONCLUSIONS To know the major pathogens and their susceptibility rates can prevent and control nosocomial infections effectively.

Objective:To establish an HPLC-ELSD method for the determination of mahuannin A in ephedrae radix et rhizoma. Methods:The content of mahuannin A was determined by an HPLC-ELSD method on an Alltima TM C18 column (250 mm × 4. 6 mm, 5 μm). The mobile phase was acetonitrile-water (28∶ 72) with a flow rate of 0. 7 ml·min-1, and the column temperature was 30℃. The temperature of drift tube heater was 105℃ and the flow rate of carrier gas was 2. 8 L·min-1 . Results:The linear range of mahua-nnin A was 42. 56-383. 04 μg·ml-1(r=0. 999 8). The average recovery and RSD was 99. 9% and 1. 96%(n=6), respectively. Conclusion:The method is simple and the result is accurate. It can be used for the quality control of ephedrae radix et rhizaoma.

Objective:To optimize the extraction process of the total flavonoids from Ephedrae Radix Et Rhizoma. Methods:The purification method of the total flavonoids from Ephedrae Radix Et Rhizoma was optimized with the yield and content of the total fla-vonoids as the indices. Based on the above research, the process parameters were optimized by an orthogonal test. Results:The opti-mum purification conditions were as follows:the volume fraction of ethanol was 50%, the stirring extraction time was 20 min, and the liquid-solid ratio was 8∶ 1(ml·g-1). Conclusion:The optimum purification technology is simple and reproducible, and suitable for the industrial production.

Objective:To study the fingerprint of Radix Salviae Miltiorrhizae of Xiangdan Injection. Methods : HPLC with UV detector was used to analyze the patterns of the Radix Salviae Miltiorrhizae of Xiangdan Injection. Protocatechuic aldehyde was used as internal standard substance. Results : The fingerprint of Radix Salviae Miltiorrhizae of Xiangdan Injection was set up and the fingerprint of them showed an excellent correlation. Conclusion : The study is helpful for the quality control of Xiangdan Injection.

Objective To construct a subtractive cDNA library of genes transactivated by XTP3 protein with suppression subtractive hybridization technique in order to clone genes associated with transactivation. Methods mRNA was isolated from HepG2 cells transfected by pcDNA3.1(-)-XTP3 and pcDNA3.1(-) empty vector respectively, and then cDNA was synthesized. After restriction enzyme Rsa Ⅰ digestion, small sizes cDNAs were obtained. Then tester cDNA was divided into two groups and ligated to the specific adaptor 1 and adaptor 2 respectively. After being hybridized with driver cDNA twice and underwent two times of nested PCR, tester cDNA was subcloned into T/A plasmid vectors to set up the subtractive library. Amplification of the library was carried out with E.Coli strain JM109. The cDNA was sequenced and analyzed in GenBank with Blast search after PCR. Results The amplified library contained 30 positive clones. Colony PCR showed that 23 clones contained 200-1 000bp inserts. Sequence analysis was performed also. It was found that 20 kinds of known and 2 kinds of novel cDNA sequences may be target genes transactivated by XTP3 protein. Conclusion The subtractive library of genes transactivated by XTP3 protein was constructed successfully. It provides a foundation for the further research on pathogenesis of the viral proteins.
