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.

Functional imaging method of biological electrical characteristics based on magneto-acoustic effect gives valuable information of tissue in early tumor diagnosis, therein time and frequency characteristics analysis of magneto-acoustic signal is important in image reconstruction. This paper proposes wave summing method based on Green function solution for acoustic source of magneto-acoustic effect. Simulations and analysis under quasi 1D transmission condition are carried out to time and frequency characteristics of magneto-acoustic signal of models with different thickness. Simulation results of magneto-acoustic signal were verified through experiments. Results of the simulation with different thickness showed that time-frequency characteristics of magneto-acoustic signal reflected thickness of sample. Thin sample, which is less than one wavelength of pulse, and thick sample, which is larger than one wavelength, showed different summed waveform and frequency characteristics, due to difference of summing thickness. Experimental results verified theoretical analysis and simulation results. This research has laid a foundation for acoustic source and conductivity reconstruction to the medium with different thickness in magneto-acoustic imaging.

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.

ObjectiveTo evaluate the clinical efficacy and safety of astragalus injection on the immune function in patients with senile sepsis.Methods Sixty patients with old age sepsis in Critical Care Medicine Department of Guangdong Provincial Traditional Chinese Medicine Hospital were enrolled and randomly assigned into control and treatment groups according to the table of random numbers, 30 cases in each group. According to 2012 sepsis guidelines for treatment, including antibacterial drug, mechanical ventilation, visceral function support, etc., the therapy was given to the control group; besides the treatment in the control group, intravenous drip of 60 mL astragalus injection(10 mL per ampoule) in 250 mL 0.9% normal saline was additionally given in the treatment group, once a day for 7 days. Before and after treatment, the immunological indexes, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment(SOFA) score, duration of mechanical ventilation and time of stay in intensive care unit(ICU), 28-day mortality and adverse drug reactions were compared between the two groups.Results Before treatment, there were no statistically significant differences in CD3+, CD3+CD4+, CD3+CD8+ and T helper cells /T suppressor cells(Th/Ts)levels between the two groups(allP>0.05), while CD3-NK+ of the control group was significantly higher than that in the treatment group〔(10.47±6.22)% vs. (6.26±4.13)%,P<0.05〕. After treatment in treatment group, CD3+, CD3+CD4+ and CD3-NK+ were increased, CD3+CD8+,Th/Ts were decreased compared with those before treatment; in the control group after treatment, CD3+,CD3+CD8+ and CD3-NK+ were decreased and CD3+CD4+ and Th/Ts increased compared with those before treatment. In the comparisons between the treatment group and control group after treatment, the differences in CD3+, CD3+CD4+ and CD3+CD8+ had statistical significance〔CD3+:(30.30±17.17)% vs.(41.91±22.29)%, CD3+CD4+:(31.54±13.24)% vs.(40.08±15.28)%, CD3+CD8+:(14.25±8.10)% vs.(9.52±9.33)%,allP<0.05〕; while the differences in Th/Ts and CD3-NK+ had no statistical significance(bothP>0.05). After treatment in the treatment group, IgG was increased compared with that in the control group〔IgG(g/L): 13.07±5.43 vs. 10.10±3.96,P<
0.05〕. The differences in IgA, IgM, complement(C3,C4) and total serum complement activity(CH50) in the comparisons between the two groups had no statistical significance after treatment(allP>0.05). The differences in APACHEⅡ score(13.83±6.18 vs. 15.90±7.48), SOFA score(7.38±4.66 vs. 6.89±4.19), time of stay in ICU(day: 11.63±5.13 vs. 13.62±8.08), invasive ventilation time(hour: 155.44±119.68 vs. 224.08±174.15) and noninvasive ventilation time(hour: 55.55±42.24 vs. 98.57±43.17) had no statistical significance in comparisons between the treatment group and control group after treatment(allP>0.05). The difference in 28-day mortality had no statistical significance in comparison between the treatment group and control group〔16.7%(5/30) vs. 20.0%(6/30),P>0.05〕. In 60 cases, there were 2 patients with adverse drug reaction, one diarrhea and another little rashes, the rest of the patients did not appear any drug side effect.ConclusionAstragalus injection combined with conventional western medicine therapy possibly has certain effect on adjustment of disturbance of immunologic functions in old patients with sepsis, and its therapeutic safety is well.
