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

Objective To study the role of transforming growth factor-?1(TGF-?1) and bone morphogenetic protein 2 (BMP2) in the ankylosing spondylitis, and to evaluate whether synovial levels of TGF-?1/ BMP2 mRNA and TGF-?1/BMP2 protein expression correlate with disease activity and macroscopic observation during arthroscopy. Metheds TGF-?1/BMP2 mRNA and protein were detected by in situ hybridization and immunohistochemistry.The vascular morphology of synovial membrane was assessed for vascular morphology, tortuous vessels, straight vessels, vascular density, synovial hypertrophy, by 2 blinded observers and Reece's method using a validated VAS methods. They were significantly higher in AS than that in RA in different synovial regions. Results TGF-?1 mRNA and TGF-?1 expression were significantly higher in early AS than that in early RA in perivascular region and sublining interstitial tissue. BMP2 mRNA and BMP2 expression were significantly higher in AS than that in RA in different synovial regions.No significant relation was found between TGF-?1/BMP2 expression and CRP/ESR/platelet count in early AS. A positive relation was found between the TGF-?1 and synovial hypertrophy in synovium lining layer region, and between TGF-?1 and straight vessels,vascular density in perivascular region, and between BMP2 and synovial hypertrophy in sublining region in early AS. Conclusion Expression of TGF-?1 mRNA and TGF-?1 protein is higher in AS synovial tissue than that in RA. BMP2 mRNA and BMP2 expression are significantly higher in AS than that in RA.

Objective To investigate spinemagnetic resonance imaging(MRI) findings in patients with axial spondyloarthritis (SpA) and to analyze the correlation between imaging and clinical manifestation.Methods The clinical data of patients with axial SpA were recorded.All patients underwent whole spine MRI scanning.The MRI findings of spinal involvement were explored.Moreover,the correlation between lesions in spinal MRI and Bath Ankylosing Spondylitis Disease Activity Index(BASDAI),Bath Ankylosing Spondylitis Functional Index (BASFI),Bath Ankylosing Spondylitis Metrology Index (BASMI),nocturnal pain visual analogue scale (VAS) score,back pain VAS score,global disease activity VAS score,Ankylosing Spondylitis Disease Activity score (ASDAS),erythrocyte sedimentation rate,C-reactive protein was analyzed.Results Thirty-three patients with axial SpA were included in this study.The image abnormalities of the spine were confirmed in 29 axial SpA patients by MRI,including Romanus lesion,Andersson lesion,the inflammation of facet joints and syndesmophyte.In correlation study,BASMI was positively correlated to the numbers of acute Romanus lesions,chronic Romanus lesions,chronic Andersson lesions and whole spinal lesions(r =0.440,P<0.05; r =0.483,P<0.05; r=0.421,P<0.05; r=0.589,P < 0.05 respectively).There was a statistically significant correlation between chronic Andersson lesions and BASFI(r =0.392,P <0.05).But no significant associations were found between MRI lesions and other clinical findings.Conclusions MRI lesions in axial SpA were associated with findings reflecting the spinal function,which can better guide the clinical treatment.

Objective To improve the understanding of severe anaphylactic reactions to infliximab retreatment. Methods Delayed hypersensitivity to infliximab in two patients with ankylosing spondylitis who had previously received infliximab and resumed after discontinuation over 4 years were reported and the related literatures were reviewed. Results Two patients ( 1 male, 1 female ) who were diagnosised with ankylosing spondylitis for more than 10 years, both individuals had received infliximab treatment during a clinical trial approximately 4-5 years prior to further therapy. On day 6 after subsequent infusion, one patient had pruritic skin rash covering her whole body, followed by flustered, dyspnea, hypotension and anaphylactic shock, she was successfully treated with epinephrine and glucocorticoid. Another patient experienced a skin rash and itching 9 days after reinfusion, he was successfully treated with antihistaminics.Conclusion A distant infliximab retreatment is associated with high rates of reinfusion reactions, including fever, urticaria, myalgia, arthralgia,even hypotension, dyspnea, laryngeal edema and anaphylactic shock.We recommend careful monitoring of those patients who receive infliximab retreatment, particularly after a lengthy interval.

Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

Objective:To explore the correlation among serum cardiac troponin I (cTnI),N terminal pro brain natri-uretic peptide (NT-proBNP)and main endpoint events of heart in patients with chronic stable heart failure.Meth-ods:The present study enrolled 95 patients with NYHA cardiac function class III~IV from Feb 2010 to Feb 2011.According to levels of cTnI and NT-proBNP,the patients were divided into cTnI negative group (n=60)and cTnI positive group (n=35);NT-proBNP negative group (n=40)and NT-proBNP positive group (n=55),all patients were followed up for two years,and the main endpoint events were cardiogenic sudden death and rehospitalization caused by acute aggravation of heart failure.Results:Compared with negative group,the hazard ratio (HR)of end-point events was 2.69 and confidence interval (CI)was 1.54~ 4.72,P = 0.002 in cTnI positive group;HR was 2.54 and CI was 1.35~4.78,P =0.003 in NT-proBNP positive group;further interclass crossover analysis found that,when patients'cTnI and NT-proBNP were both positive,the hazard ratio of cardiac endpoint events was the highest (HR=6.34,CI 2.26~17.9,P <0.001).Conclusion:In patients with chronic stable heart failure,serum elevated levels of cardiac troponin I and N terminal pro brain natriuretic peptide are important predictors reflecting prognosis of patients with heart failure.
