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.

Objective To assess clinicopathological features and prognosis of patients with combined hepatocellular and cholangiocarcinoma (cHCC-CC). Methods Clinicopathological and follow-up data of 115 cHCC-CC patients confirmed pathologically in Liver Cancer Institute of Fudan University from 1995 to 2007 were analyzed. Kaplan-Meier method was used to calculate 1-,3- and 5-year survival rates and tumor-free survival rates. Survival curves were analyzed using the log-rank test. The factors that impacted the prognosis of cHCC-CC were estimated. Results In 115 cases, one was Allen's type A, one was Allen's type B, and the other 113 were Allen's type C. Being with male in predominance, most of the cHCC-CC patients had liver cirrhosis background. They presented with elevated AFP or CA19-9, vascular invasion, resembling hepatocellular carcinoma(HCC)as well as lymph nodes metastasis. One-, 3-, 5-year survival rates of 115 patients were 68. 1%, 38. 1% and 33.6%, respectively, with median survival time of 13.0 months. Whereas the 1-, 3-, 5-year survival rates in radical resected patients were 78.4 % ,44.4 % and 44.4 % ,respectively, with median survival time of 16.0 months. Tumor free survival time at 1-, 3- and 5-year was 57.8 %, 12.6 % and 0.0 %,respectively,with median recurrent time of 10.0 months. One-, 3-, 5-year survival rates of 10 nonsurgical patients were 10/10,10/10 and 0/10,respectively, with median survival time of 5.3 months.TNM stage was independent factor for prognosis of the patients after resection. Whereas the lymph nodes involvement was independent factor for the tumor free survival time of radical resected patients.Conclusions Although clinicopathological characteristics of cHCC-CC are more similar to those of HCC, the prognosis of cHCC-CC is more unfavorable than that of HCC. TNM stage is an independent determinant of long time outcome for patients after resection.

ObjectiveTo study the protective effects of Qiqiong(QQJN) on focal cerebral ischemia/reperfusion injury and its mechanism. MethodsMiddle cerebral artery occlusion(MCAO) was used to make focal cerebral ischemia/reperfusion model by intravascular nylon filament occlusion. The protective effects of QQJN were evaluated by investigating neurological function score, percentage of cerebral infarction, pathomorphology of brain, the activity of SOD and the content of MDA in hrain tissue,thrombogenesis and platelet aggregation in vitro. ResultsCompared with model group, QQJN(4.4、8.8g/kg)could decrease the neurological score in 8 and 22h after reperfusion, reduce the percentage of cerebral infauction,improve pathomorphology of brain, decrease the length, wet weight and dry weight of thromb and inhibit platelet aggregation. ConclusionQQJN had protective effects on focal cerebral ischemia/reperfusion injury. The role of anti-injury of free radicals,inhibit thrombogenesis and platelet aggregation should contribute to its neuroprotective effects.

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.
