The shell effect is included in the improved isospin dependent quantum molecular dynamics model in which the shell correction energy of the system is calculated by using the deformed two-center shell model. A switch function is introduced to connect the shell correction energy of the projectile and the target with that of the compound nucleus during the dynamical fusion process. It is found that the calculated capture cross sections reproduce the experimental data quantitatively at the energy near the Coulomb barrier. The capture cross sections for reaction 35 80 Br + 82 208 Pb → 1.7 288 X are also calculated and discussed.

Avian influenza virus（AIV） nonstructural 1.NS1. gene was amplified by real-time polymerse chain reac tion（RT-PCR） and inserted into pET28a, then transformed into E. coli BL21.DE3） competent cell. With the induction of isopropyl-β-D-thiogalactoside（IPTG） and the purification of Ni-NTA column, we finally obtained purified NS1.protein. T7-phage display system was used to screen the proteins that interacted with NS1.from lung cell cDNA li brary. The selected positive clones were identified by DNA sequencing and analyzed by BLAST program in Gene Bank. Two proteins were obtained as NS1.binding proteins, Homo sapiens nucleolar and coiled-body phosphoprotein 1.NOLC1. and Homo sapiens similar to colon cancer-associated antigen. By co-immunoprecipitation and other me thods, Homo sapiens NOLC1.was found to interact with the NS1.protein, the results would provide the basis for fur ther studying biological function of NS1.protein.
