Objective To study the feasibility, safety, effectiveness of left atrial circumferential ablation of pulmonary veins for atrial fibrillation(Af) guided by EnsiteNavX mapping system. Methods Seventeen patients with paroxysmal or persistent Af were included. Real time 3-dimensional left artial (LA) and pulmonary veins (PVs) maps were constructed through EnsiteNavX mapping system. Pulmonary veins isolation was performed by encircle the left and right sides PVs at adistance of 1 to 2 cm away from the ostium of PVs. Results Seventeen patients were all reached the endpoint of abalation completely. The mean procedure time and fluoroscopy time were (226.1 ± 36.2) minutes and (41.3 ± 12.8) minutes. Mean radiofrequency energy delivery time was (61.9 ±15.4) minutes. Recur-rence of Af occurred in two patients, one was repeat ablation succnssfully. During 3 ~ 36 months followup, fourteen patients (82.3%) were free of Af without any antiarrhythmic drugs. Recurrence of Af occurred in three(11.7%) patients treated with amiodarone. No complications occurred during the procedure and the following up. Conclusion Left atrial circumferential isolation of pulmonary veins for Af guided by Ensite NavX mapping system was effective and salty.

Magnetoacoustic tomography (MAT) has some advantages such as high sensitivity and high spatial resolution. The generating mechanism of acoustic source is the research foundation of forward and inverse problems. A coustic signals were respectively simulated by using monopole and dipole radiation theory in the experimental conditions, then the differences between their acoustic pressures were discussed, and furthermore the contrast and validation were conducted by physical experiments in this study. The physical experimental results showed that acoustic waveform of MAT had a certain directivity and therefore they indicated that dipole model showed higher approximation to the real facts than monopole model. It can be well concluded that this research has cardinal significance for the accurate algorithm of MAT.

Objective To investigate the influence of perioperative continuing aspirin therapy on tooth extraction surgery in elderly patients with coronary heart disease.Methods A total of 926 patients with coronary heart disease who required tooth extraction were enrolled in this study.Among them,241 patients discontinued aspirin therapy before tooth extraction,685 patients continued aspirin therapy before tooth extraction.The entering rate of operation was evaluated.100 patients continuing aspirin and 100 patients discontinuing aspirin were randomly selected.Systemic pressure,diastolic pressure and heart rate before and after tooth extraction were detected.100 matched healthy elderly patients were selected as normal control group.Multivariate logistic regression analysis was used to estimate the risk for tooth extraction.Results The entering rate of operation was 67.9% (131 cases) in 193 patients with angina pectoris discontinuing aspirin therapy and 82.1 % (312 cases) in 380 patients with angina pectoris continuing aspirin therapy (x2 =14.77,P<0.01).The entering rate of operation was 41.7% (20 cases) in 48 patients undergoing coronary revascularization and discontinuing aspirin therapy,and 80.7% (312 cases) in 305 patients undergoing coronary revascularization and continuing aspirin therapy (x2=33.95,P<0.01).The changes in systolic blood pressure before versus after dental extraction had a significant difference between the discontinuing aspirin group and control group [(15.9±5.5) mmHg vs.(12.2±4.7)mmHg,P<0.05,1 mmHg=0.133 kPa],while had no significant difference between the continuing aspirin group and control group [(13.6±4.5) mmHg vs.(12.2±4.7) mmHg,P>0.05].There were no significant differences in changes in diastolic blood pressure and heart rate in the intraoperative period between the patients and controls (P>0.05).The bleeding rate in patients continuing aspirin therapy was not significantly different as compared with control group (P> 0.05).Multivariate logistic regression analysis revealed that perioperative discontinuing aspirin therapy remained the second significant risk factor for tooth extraction.Conclusions Preoperative administration of aspirin should be continued in dental extraction surgery in elderly patients with coronary heart disease.

To study the specific cytotoxicity T lymphocyte (CTL) effect against tumor cells initiated by DC pulsed with peptide of cancer cell. Methods Development of cells with cytologic features of DC in bone marrow cultures supplemented with granulocyte macrophage-colony stimulus factor (GM-CSF) and IL-4. Determining the DC phenotype and the specific structure by electronic microscopy. The CTL effect against pancreatic carcinoma leading by the DC pulsed with tumor cells lysate in vitro was observed. Results A large number of typical DC was proliferated by supplementing with GM-CSF and IL-4 cytokines. DC had specific cell appearance and structure, and highly expressed various cell surface molecules. TNF-? had the ability of stimulating DC mature, the mature DC had the enhancing abilities of antigen presenting and IL-12 self-secreting, as well as, expressed higher levels of CD54, MHC-Ⅱ and CD86 molecules than control group (P
