In this research, Casuarina eguisetifolia Linn was used to verify the broadly suitability of DNA bar-codes in identification of Li-medicine plants and systematic development of species. The genomic DNA of 22 samples collected C. eguisetifolia and its adulterants were amplified by 4 pairs of primers respectively (ITS (inter-nal transcribed spacer), ITS2 (internal transcribed spacer 2), trnH-psbA , rbcL) and sequenced bi-directionally. Obtained sequences were assembled using CodonCode Aligner. The dates were analysised using MEGA5.1 in ac-cordance with the kimura 2-parameter (K2P) model. The neighbor-joining (NJ) phylogenetic trees were construct-ed. Our study demonstrated the efficacy of ITS/ITS2 to distinguish between C. eguisetifolia and other adulterants species at the molecular level. Comparative to the primer of trnH-psbA and rbcL, there was a obviously DNA gap. The NJ trees showed that the several species of Casuarina can be classified to same types to show a obvi-ously monophyly, which the nearest family was Guttiferae. Therefore, ITS/ITS2 regions can accurately distinguish the original plant of Li-medicine. The systematic evolution of Casuarina can be verified in the molecular level.

This research is for the purpose of comparative analysis of the microbial flora structure in the chilled beef with no packing and cling film, which under the same terms of sale. It was used the V3 area fragment of 16S rDNA to carry on PCR-DGGE, Meanwhile used the 16S rDNA sequence to analysis the microbial flora structure of the two samples, according to the technology of clone .The research discovered that the flora structure displays a biggish difference; there was 6 OTU in the chilled beef with cling film, mainly was that Lactococcus(28%), Lactobacillus (26%), Carnobacterium(18%) and Brochothrix (10%); but there was 18 OTU in the chilled beef with no packing, mainly was that Lactococcus(28%), Brchothrix(18%), Acinetobacter (11%). The result indicates that cling film played a certain inhibitory action regarding the Staphylococcus as well as the cold pole bacteria and such bacterium. And it can provide a certain theory ba-sis for the meat processing in the department of microorganism’s control.

To reduce the mismatching and non-matching in the protein two-dimension electrophoresis (2-DE) images, we proposed an auto-matching algorithm based on gray hierarchical and geometric blocking in this study. Firstly, protein spots in the gel images were divided into groups by gray level and geometric position, and then a method based on shape context and normalized correlation was used for coarse matching in protein spots. Secondly, matched pairs in coarse matching were set as feature points, and the precise matching in the rest of not matched protein spots was accomplished by the method of geometric correlation and similarity criterion. Finally, local affine transformation was used in the verification of matching results to remove non-matching and mis-matching points. The algorithm was applied to different 2-DE gel images. The results showed that the new matching algorithm could reduce the non-matching and mis-matching spots, and increase the matching accuracy.

Objective To investigate the pancreaticoenterostomy technique using end to end anastomosis of remianing pancreas and jejunum with jejunum mucus preserved. Methods 28 cases underwent pancreatectomy were observed and analyzed from May 2005 to August 2009. There were 26 cases underwent duodenopancreatectomy and 2 cases underwent the pancreatectomy of pancreas body and tail. All cases used the end to end pancreaticoenterostomy, remnant pancreas was directly anastomosed with jejunum without destroy of jejunal mucosa. During the operation, 2.0 cm~2.5 cm long remnant of pancreas was pulled into jejunum without mucosa destroyed. Then, the cut end of the jejunum was fixed on the pancreatic remnant correspondingly by interrupted suture. Finally, a 7-silk suture was used to bind the jejunum and the pancreatic remnant together 1 cm away from the cut surface of the pancreatic remnant. Results 1 case underwent operated again due to bleeding of the pancreatic remnant. 28 patients recovered and discharged from hospital without having the complication of pancreatic fistula. Conclusions Because of the complicated suturation methods, the conventional pancreaticoenterostomy consumes more time. But it still has rather high incidence of pancreatic fistula.The new pancreaticoenterostomy which we used can shorten the operating time and integrity and binding stomas. It is effective to lower the incidence of pancreatic fistula.
