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.

METHODS: Fresh human amnions were clipped to pieces which were sutured in a shape like muff by utilizing epidural tubes as a stent. When 4 cm section of ureter in length was excised to replace the defected ureter. 36 rabbit models were divided medially into the 1-month therapy and 3-month therapy groups. At the end of study, all amnion-ureter were sliced and examined with pathologic method or immunohistochemistry to check expressions of α-actin in smooth muscle cells and CKAE1/AE3 in transitional epithelial cells.
