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 observe the effect of scalp acupuncture plus body weight support treadmill (BWST) training on motor function and ambulation of lower limbs in spastic cerebral palsy. Method Sixty-six eligible subjects with cerebral palsy were divided by using random number table into group A (n=20), group B (n=23), and group C (n=23). Group A was intervened by regular rehabilitation training, group B was by BWST in addition to the treatment given to group A, and group C was intervened by scalp acupuncture in addition to the treatment given to group B. The dimension D and E of Gross Motor Function Measure (GMFM) scale and Activities of Daily Living (ADL) were adopted for evaluation before treatment and after 3-month treatment. Result Before treatment, there were no significant differences in comparing the indexes among the three groups (P>0.05). After 3-month treatment, the D-dimension scores of GMFM were respectively (25.38±4.85), (29.54±5.70), and (32.37±6.58) in the three groups; the E-dimension scores were respectively (55.35±11.64), (60.80±12.47), and (65.74±13.50); the ADL scores were (60.24±14.49), (68.25±13.74), and (76.30±14.58); the scores were significantly increased in all three groups after intervention (P<0.01), and the D-dimension and E-dimension scores of group B and C were significantly higher than those of group A (P<0.05), and the scores of group C were significantly higher than those of group B (P<0.05). Conclusion Scalp acupuncture plus BWST can improve the motor function and walking ability of lower limbs in spastic cerebral palsy, and thus enhance of ADL of the patients.

Objective To investigate the effects of different pacing sites of right ventricle on serum N terminal Pro brain natriuretic peptide (NT-ProBNP) and left ventricular systolic function.Methods A total of 76 patients with an implanted DDD pacemaker were randomly divided into right ventricular septal pacing group (RVSP group,n=40) and right ventricular apex pacing group (RVAP group,n=36) according to the ventricular leads position.Serum NT-proBNP level,left ventricular end diastolic dimension(LVEDD)and left ventricular ejection fraction(LVEF)were analyzed before and 6 months after operation in the two groups.Results There was no difference in serum NT-proBNP level between the two groups before operation,but the serum NT-proBNP level increased in both groups 6 months after operation,and it was higher in RVAP group than in RVSP group (P<0.05).There were no significant differences in LVEDD and LVEF in RVSP group before and after implantation (P>0.05).Compared with pre-implantation,LVEDD was increased and LVEF was decreased in RVAP group 6 months after implantation (both P<0.05).Linear correlation analysis showed that serum NT-proBNP level was negatively correlated to LVEF (2γ=-0.76,P<0.05).Conclusions Compared with RVAP,RVSP can keep the normal sequence of electrical activity and exert less adverse effects on left ventricular systolic function.Therefore,RVS is an ideal pacing location.
