Objective To explore the efficacy and safety of sodium nilroprusside(SNP) with remifentanil or fentanyl used for controlled hypotension during the pediatric patent ductus arteriosus (PDA) operations. Methods Sixty children undergoing operation were randomly divided into SNP with fentanyl (A group) or remifentanil (B group). Hemodynamic changes in different times and adverse reactions were observed. Results In B group, heart rate was stable and blood pressure declined quickly. The dose of SNP was fewer and hemodynamic changes and recovery from anesthesia were better in B group than in A group. Conclusion Remifentanil could potentiate the hypotensive effect of SNP and decrease adverse reaction.

Objective To establish a simple and rapid method for the extraction and detection of residual acetochlor and atrazine in environment. Methods Acetochlor and atrazine in environment were extracted and enriched efficiently by using automatic solid phase extraction system. The sample concentrations were determined by gas chromatography-mass spectroscopy with electron impact ionization and multipolar mass spectra Msn. Results The recovery rates and RSDs of the method were 79.2%-95.1% and 1.73%-8.31% respectively. The detection limit of acetochlor in water and soil were 0.1 ?g/L and 0.005 mg/kg respectively. The detection limit of atrazine in water and soil were 0.05 ?g/L and 0.002 5 mg/kg respectively. Linear range was 0-5 ?g/ml. Conclusion The SPE-GC-MS method can be used to determine acetochlor and atrazine in environment.

Objective To characterize the molecular characteristics of hemagglutinin (HA) and neuraminidase (NA) of influenza B viruses isolated in Jiangsu province,2011.Methods Thirteen strains of influenza B virus in different areas and epidemic period in Jiangsu province,2011 were selected for whole-genome sequencing,and analysis of molecule epidemic characteristics for HA and NA was carried out by bioinformatics method.Results Of the 13 randomly selected influeuza B strains,10 strains were assorted to Victoria lineage strains with NA genes from Yamagata lineage,and 3 strains belong to Yamagata lineage.Compared nucleotide and amino acid sequences of HA and NA genes with their vaccine strains respectiuely,196/197 glycosylation site appeared on HA1 gene in Yamagata/Victoria isolates virus.Conclusion Both B/Victoria and B/Yamagata lineage viruses co-circulated in Jiangsu province,and reassortant virus of Victoria lineage were predominant virus.

Objective To explore the relationship between serum cccDNA and liver damage in the patients with chronic HBV infection.Methods Serum cccDNA,ALT of 156 patients with chronic HBV infection were measured,and pathology of liver tissue in 85 patients was detected.Results The positive rate of Serum cccDNA and ALT had no significant difference(P＞0.05).Between pathology light,medium and severe group,S0_(～1) and S_(2～4) group,G_(0～1) and G_(2～4) group the serum cccDNA mean was significantly different(P＜0.01).The positive rate of serum cccDNA was significantly different between the group of NAASC and ASC,CH,LC,HCC,and the group of ALT ≤40u/Land 40～80,80～400,≥400u/L(P＜0.01).Conclusion Serum cccDNA and liver inflammation,fibrosis and ALT had no relevance,serum cccDNA with at a low level may be non-active,but should be excluded from serious liver diseases.

Data mining, as known as knowledge discovery in databases, is a non-trivial process of revealing the implied, previously unknown and potentially useful information from the massive data. In recently years, the applications of data mining in the field of pharmaceutical research of traditional Chinese medicine have widespread. Especially in the field of the heritage of experiences of na-tional medical masters, data mining plays an important role. In this study, we would expound of the use of methods of data mining in the heritage of experiences of national medical masters, and analyze their advantages and disadvantages, such as association rules, Bayesian networks, neural networks, and decision trees.

Objective To compare four methods of monitoring vascularization of tissue engineered bone in the rhesus so as to find our the best. Methods Twenty-five lower limbs of 13 rhesuses were used in this study to make models of tibial diaphyseal defect of 20mm which were to be fixed with an AO reconstruction plate of 7 holes. The monkeys were randomly divided into five groups according to defect filling materials: group A:?-tricalcium phosphate (?-TCP) and bone marrow stromal cells (BMSCs) and blood vessel bundles; group B:?-TCP and blood vessel bundles; group C:?-TCP and BMSCs; group D:?-TCP; group E: blank. Perfusion weighted MR imaging (PWMR), X-ray, radionuclide imaging and histological examinations were carried out at weeks 4, 8, 12 postop- eratively. The maximum slope rates of the single intensity-time curve (SS_(max)) and values of baseline (Sl_(?))were calculated at the same time points. Transmittances of the X-ray films were assessed. Ratios between isotope counts in region of interest (ROI) were calculated. Chinese ink perfusion and calculation of blood vessel areas were done for histological examinations, Results Compared with other groups, the SS_(max) in group A was the highest at weeks 4, 8, 12 postoperatively. In group A, the SS_(max) at week eight was significantly higher than that at week four (P= 0. 003), and the SS_(max) and transmittance of X-ray were negatively related at week 12 after operation (rs=-0. 892, P=0. 042), but the SS_(max) and blood vessel area were positively related (rs=0. 894, P=0.041)Conclusions PWMR can be a sensitive, quantitative, noninvasive and non-radiant method to monitor vascularization of tissue engineered bone, because SS_(max) of the single intensity-time curve of PWMR can reflect the most accurately the process of vascularization of tissue engineered bone.

To examine the effects of heterologous expression of ZrGPD1 (encoding glycerol 3-phosphate dehydrogenase ) cloned from osmotolerant yeast Zygosacharomyces rouxii on glycerol production in wild Pichia farinosa,the URA3 gene was amplified from P. farinosa as the homology integrative region. A recombinant plasmid (pUR-ZG) was constructed then transformed into P. farinosa by electroporation. The transformant pfa-gu was obtained by the selectable marker Zeocin TM . Primary results showed that the biomass of pfa-gu was higher than the wild type in the flask and after 72h fermentation the concentration of glycerol of pfa-gu was 37g/L enhanced 30% in comparison with the wild type. It is concluded that heterologous expression of ZrGPD1 is useful for increasing glycerol production and the ability of osmoregulation in P. farinosa.
