A hammerhead RZ DNA was designed and synthesized, which can specifically cleave the bcl-2 mRNA. After demonstration of right sequences by sequencing and cleavage activity of RZ by in vitro cleaving experiment, The RZ DNA was recombinated into the pDOR - neo vector to form the recombinant pDOR - RZ. Using lipofectin - mediated DNA transfectionpDOR-RZ was successfully introduced into HL - 60 cells. The RZ expression was observed by Southern, RNA dot blot hybridization and flow cytometry (FCM) . The results demonstrated that (a) the RZ was expressed in 72 hours after transfection; (b) the synthesis of Bel - 2 protein was inhibited by the expression of RZ; (c) apoptotic peak appeared in FCM.

Objective To set up rodent ankylosing spondylitis model. Methods Recombinant natively folded versican G1 domain(VG1) and FCA were injected into BALB/c mice to induce spondylitis and sacroiliitis. Spondylitis and sacroiliitis were determined by pathological examination. Results It was shown that immunity to recombinant VG1 resulted in spondylitis in the lumbar spine and sacroiliitis in 35 0% and 12 5% mice respectively. Accumulation of mononuclear cells was observed in spinal ligaments adjacent to the intervertebral disc, the intervertebral disc and the sacroiliac joints. No clinical peripheral arthritis was observed. Conclusion These observations suggest that immunity to human VG1 is involved in the induction of experimental spondylitis and sacroiliitis in BALB/c mice, which will do some help to probe the pathogenesis of human ankylosing spondylitis
