Objective To confirm that if the integrality of NF has effect on the shape and distribution of NLY. Methods using SABC monocolon antibody immunohistochemistry,electron microscopy,immunocytochemistry, and enzymocytochemistry to observe the disorder of NF-H and the changes of distribution and shape of NLY after vanadate treated. Results When the integrality of NF was damaged, the proteins of NF gathered towards nuclear accompany with the similar movements of NLY, meanwhile the shape of NLY also changed into round from thread-like shape.Conclusion Through different ways we used, vanadate can over-phosphate NF proteins and destroy the assemble ability. Whether NF has a complete structure is important to the shape and distribution of NLY, which will be changed when the structure of NF is disorganized.

Objective To analyze comparatively the outcome of modified Manipal and DeVega tricuspid annuloplaaty.Methods From Oct.2001 to Aug.2004,the consecutive 123 patients operated with modified Manipal tricuspid annuloplasty for tricuspid re- gurgitation at the time of left cardiac valve replacement(group A)were elected in this study.The other 174 patients operated with De Vega tricuspid annuloplasty at the time of left cardiac valve replacement were elected randomly for control(group B).There were no significant differences of the patient data before surgery between two groups.Results There were overall 11 early deaths(4 in group A,7 in group B),The overall in-hospital mortality rate was 3.7 %.215 of the 286 surviving patients were followed;the overall follow up was 75.2 %.Mean follow-up was(28.4?9.1)months(range from 13 to 49 months).There were ten late deaths and the late mortality rate was 4.7%.There was no significant differences in the patients with 3+~4+ tricuspid regurgitation at follow-up 18,30 and 42 months in group A;but there was an increase of the patients with 3+~4+ tricuspid regurgitation with an incremental follow up term in group B(P

Objective To establish a multiplex loop-mediated isothermal amplification(mLAMP)method for simultaneous detection of Salmonella,Vibrio parahaemolyticus (VPH)and Listeria monocytogenes (LM).Methods Three sets of mLAMP primers were designed to specifically target bcfD of Salmonella and tlh of VPH and iap of LM.The respective single LAMP assay of the three kinds of bacteria was developed,and the ratio of primer concentration was optimized to develop a multiplex LAMP system.The specificity and sensitivity of multiplex LAMP were observed.Results Turbidity monitoring results in real time suggests that the mLAMP was highly specific and amplification could be obtained within 45 min under isothermal conditions.The sensitivity of this mLAMP was found to be 300 fg/μl genomic DNAs for Salmonella and 4.2 pg/μl for VPH and 4.5 pg/μl for LM,which was consistent with conventional PCR.Conclusion The mLAMP described can potentially facilitate simultaneous detection of three kinds of bacteria in a large number of food samples, which could be used as a primary screening method and as a supplement to classical detection methods.

To obtain the key genes for chlorogenic acid biosynthesis of Lonicera hypoglauca, four new genes ware obtained from the our dataset of L. hypoglauca. And we also predicted the structure and function of LHPAL4, LHHCT1 , LHHCT2 and LHHCT3 proteins. The phylogenetic tree showed that LHPAL4 was closely related with LHPAL1, LHHCT1 was closely related with LHHCT3, LHHCT2 clustered into a single group. By Real-time PCR to detect the gene expressed level in different organs of L. hypoglauca, we found that the transcripted level of LHPAL4, LHHCT1 and LHHCT3 was the highest in defeat flowers, and the transcripted level of LHHCT2 was the highest in leaves. These result provided a basis to further analysis the mechanism of active ingredients in different organs, as well as the element for in vitro biosynthesis of active ingredients.

SMART-RACE was performed after isolating the total RNA of Armillariella tabescens to amplify the full-length cDNA of arabinosidase (GenBank Accession No. AJ620046). Bioinformatics analysis was used to analyze the code frame of arabinosidase, to predict its structure and function. Recombinant plasmid pPIC9-AF was constructed and then electroporated into methylotrophic yeast Pichia pastoris GS115. The secreted 6 ? His fusion protein was purified to analyze its enzymology property. This arabinosidase had high activity at 30-35℃ under acid condition, and was stable within wide range of pH and temperature. It maintained about 80% activity at the range of pH4. 0-8.0 and 20-40℃,wider than many other cloned arabinosidase. So it was worthy to go step further to study this enzyme, and recombinant expression provided a chance of highly expressing arabinosidase.
