Objective To investigate the correlation between the distribution of lesions on MRI and the findings of computerized tomography angiography (CTA) in patients with posterior circulation infarction.Methods Patients with acute posterior circulation infarction were enrolled in the study.The sites of the infarcts were divided into proximal,middle and distal infarctions according to the results of MRI.All the patients received head and neck CTA.The correlation between the distribution of posterior circulation infarcts and the sites of vertebrobasilar system lesions was analyzed.Results A total of 203 patients with acute posterior circulation infarction were enrolled.Their primary clinical symptoms and signs were unilateral limb weakness (n =77,37.93％),dizziness (n =129,63.55％),dysarthria (n =31,15.27％),nausea and vomiting (n =61,30.05％),headache (n =79,38.92％),gait abnormal (n =50,24.63％),nystagmus (n=34,16.75％),and ataxia (n=21,10.34％).Proximal infarction (n=35,17.24％):medullary infarction (n =28,13.79％),posterior inferior cerebellar artery infarction (n =7,3.45％); middle infarction (n =95,46.79％):pontine infarction (n =80,39.4％),anterior inferior cerebellar infarction (n =15,7.39％); distal infarction (n=73,35.96％):middle cerebral infarction (n=6,2.96％),superior cerebellar infarction (n =16,7.88％),thalamic infarction (n =34,(16.75％),occipital lobe infarction (n =10,4.93％),temporal lobe infarction (n =7,3.44％).Extracranial vertebral artery lesions were most common in the distal infarction group.It reached 53.42％,and was significantly higher than 22.86％ in the proximal infarction group (P =0.003) and 33.68％ in the middle infarction group (P =0.010).Intracranlal vertebral artery lesions were most common in the proximal infarction group.It reached 57.14％,and then followed by the middle infarction (41.05％).They were all significantly higher than 15.07％ in the distal infarction group (all P =0.000).Basilar artery lesions were most common in the middle infarction group.It reached 20.00％ and was significantly higher than 4.11％ in the distal infarction group (P=0.002).Posterior cerebral artery lesions were most common in the distal infarction group.It reached 27.40％ and was significantly higher than 5.71％ in the proximal infarction group (P =0.009) and 5.26％ in the middle infarction group (P=0.000).Conclusions The range of vascular lesions of the distribution of lesions shown on MRI and the findings of CTA on vertebrobasilar artery system in patients with posterior circulation infarction had some connection.During the proximal and middle infarctions,the possibility of having intracranial vertebral artery lesions was greater; during the distal infarction,the possibility of having extracranial vertebral artery and posterior cerebral artery lesions was greater.

Objective To discuss the application of implantation temporary cardiac pacing by balloon-tipped floating catheter for peroperative period patients. Method Thirty-three patients with severe bradyarrhythmia were received the balloon-tipped floating catheter to RV by Seldinger puncture technique.Meantime, the pacing signals of ECG were observed. The threshold and QRS waves to ensure the electrode position were determined. Result All of 33 cases were successfully punctured and 32 cases get paced, except 1 case had the electro - mechanical dissociation (EMD). Pacing threshold was less than 0. 9V, and mean remaining time was 12.47 ～ 161 (67. 05 ±34. 48) hours. Apical pacing was operated in 23 patients,and right ventricular outflow tract pacing in 10 patients. No severe complications were occurred. Conclusion The implantation method of temporary cardiac pacing by balloon-tipped floating catheter was convenient and safe. It could help the patients get safety in anesthesia and peroperative period.

It’s still controversial whether there is specificity of acupoints, because numerous studies showed that stimulation to acupoints and sham acupoints produced parallel clinical efficacies. For example, acupoint specificity was not detected when Visual Analogue Scale was adopted to evaluate pain, while hemodynamic and neuroimaging studies suggested the existence of acupoint specificity. This article reviewed and summarized relevant studies that supported or didn’t support acupoint specificity. Further researches are required to prove the existence of specificity of acupoints.

Objective: To explore the feasibility and safety of three dimensional (3D) electro-anatomical mapping system (Carto3) in treating the patients with paroxysmal supra-ventricular tachycardia (PSVT) by radiofrequency catheter ablation (RCFA).
Methods: A total of 180 PSVT patients were divided into 2 groups, n=90 in each group. 3-D group, the patients received RCFA with 3-D reconstructed valve ring model under Carto3 guidance. 2-D group, the patients received RCFA under conventional X-ray guidance. The procedural and X-ray exposure times, rates of success and complications, tachycardia recurrence at 6 months after procedure and the cost were observed and compared between 2 group.
Results: The procedural time was similar between 2 groups, P=0.1403. The patients in 3-D group had the lower X-ray exposure time (2.1 ± 0.7 vs 7.8 ± 3.6) min, particularly in those with right-sided accessory pathway (3.4 ± 0.7 vs 20.2 ± 7.1) min, and dual atrio-ventricular (A-V) nodal pathways (1.1 ± 0.3 vs 5.5 ±1.7) min, all P<0.0001. There was 1 patient in 3-D group without RCFA and all the others were successes. 2-D group had 3 patients with failed RFCA including 2 of right-sided accessory pathway, 1 of dual A-V nodal pathways and received 2nd RCFA under Carto3 guidance. 3-D group had no complication, no recurrence. In 2-D group, 1 patient suffered from complete A-V block (AVB) during ablation and 1-year later, the Holter showed II° to III° AVB;2 patients with recurrence including 1 of dual A-V nodal pathways and had successful 2nd ablation. The cost was higher in 3-D treatment.
Conclusion: RFCA was feasible for treating PSVT patients under Carto3 guidance, which had the higher success rate with lower X-ray exposure and complication.
