Some evidence indicates that the combination of extrinsic, intrinsic and genetic factors all play a role to cause the disc degeneration, with a progressive decrease in proteoglycan content leading to dehydration of the nucleus pulposus, and Type Ⅰ collagen begins to appear in the matrix, the ratio between Type Ⅰ and Type Ⅱ increases. All these cause the swelling pressure, disc height and the disc load bearing ability decrease. The disc progressively herniate and cause radiculopathy and myelopathy.

In this study, the DNA fragments coding for amino acids 133~158 of VP1and 20~34 of VP4protein of type Asial FMDV were chemically synthesized and ligated into a tandem repeat 133~158-20~34-133~158. The sequences of signal peptide of Igκ chain and Kozak were fused to the 5'end of this tandem sequence and synthetic oligodeoxynucleotide containing CpG-ISS was fused to downstream of terminal coden of this tandem sequence. And then this long fragment was cloned into the eukaryotic expression plasmid pHook-2, forming a new secreted expression plasmid, named pAS1-E.
