Secondly, three kinds of mathematics model of optical vortex beams were introduced here. Then the propagation dynamics of optical vortex beams through the non-axis symmetry system is studied, this chapter includes the introduction of the symmetry vortex beam and the non- symmetry vortex beam, the deduction of the Collins diffract integral formula for the non-axis symmetry system, and the transformation of the vortex beam passing through the non-axis symmetry system has been described by using the numerical simulation. Then the general calculation for the orbit momentum of vortex beams, the matrix form for the orbit momentum of vortex beams, and the photon method to describe the orbit momentum of vortex beams are also introduced here. Finally, the interference about optical vortex beams was studied.

Methods The total RNA was extracted from the brain of human embryo. The segment of open read frame of DOC-1 was amplified by RT-PCR and was further cloned into the vector, pMD18-T, and the prokaryotic expression vector, pGEX-4T-1, by turns, to produce the new construct pGEX-4T-1-DOC-1. After restriction enzymes digestion analysis and sequenced, pGEX-4T-1-DOC-1 was transformed into E.coli BL21（DE3）. GST-p12 recombinant protein was expressed under IPTG induction and purified by affinity column.
