Objective To evaluate feasibility, effectiveness , safety, and complications of superselective bronchial artery embolization with coaxial microcatheter system for hemoptysis. Methods 32 times of superselective bronchial artery embolization were performed for 29 cases with hemoptysis resulted from a variety of causes, age grade from 35 to 71(mean 54) year old. The causes of hemoptysis included bronchiectasis (9 cases), tuberculosis (12 cases), and pulmonary carcinoma (8 cases). All studies were performed with standard percutaneous transfemoral catheterization. Results The success rate of superselective catheterization was 96 9% (32/33). Hemoptysis control was achieved in 96 9% (31/32), with complete control rate of 65.6% (21/32) and partial control rate of 31.3% (10 /32),inefficacy case:only one.One patient with bronchiectasis, 6 patients with pulmonary carcinoma and 3 patients with chronic fibrosis tuberculosis were included in the partial control group. Rebleeding occurred in 7 patients (4 patients with pulmonary carcinoma and 3 patients with chronic fibrosis tuberculosis) during 2 months to 32 months followed-up period. No severe complications occurred in the procedure. Conclusions Superselective bronchial artery embolization for hemoptysis with coaxial microcatheter is a safe, effective way to control hemoptysis, has excellent long term efficacy, and without severe complications.

Objective To evaluate the efficiency, safety and complications of transcatheter closure of atrial septal defect (ASD) using Amplatzer and sideris occluder under the guidance of transthoracic echocardiography and fluoroscopy. Methods Fourteen patients of ASD, 6 male and 8 female, age ranged from 2.6 to 43 years old, were treated by transcatheter closure of ASD with Sideris or Amplatzer occluders. All cases were guided by thansthoracic echocardiography and fluoroscopy. Results The diameter of ASD (balloon stretched diameter) was 14-34 mm (24.16 ? 5.16)mm. The Amplatzer devices were used in 9 cases, all of them were successfully occluded with satisfactory results. Of 5 patients treated by Sideris buttoned devices, 4 had success procedure and one failed, in which unbuttoning occurred and retrieval of the device was performed by emergency surgery. Conclusion Transcatheter closure of ASD is a simple and convenient method with a high success rate and reliable curative effect. The indication of Amplatzer method is much wider and the instant success rate after the procedure is much higher than those of Sideris device. Thansthoracic echocardiography plays a key role for guiding transcatheter closure of ASD in this study.

OBJECTIVE:To study the cytotoxicity of the graft polymer after polyethyleneimine (PEI) had been modified by polyoxyethylene stearate (POES) and the property of the carrier,grafted-polymer/DNA complexes. METHODS: To modify PEI by conjugating PEI to POES with succinimidyl carbonate method. Structural analysis of synthesized polymer was performed by using 1H-NMR. Agarose gel electrophoresis (AGE) behavior of the graft polymer/DNA complexes was observed with particle size and zeta potential measured. The cytotoxicity of the graft polymer was evaluated by MTT method. The pGL3-lus served as a reporter gene,and the luciferase activity was determined to evaluate the transfection efficiency of grafted-polymer/DNA on Hela cells. RESULTS: 1H-NMR showed that the graft polymer had high purity. AGE showed that the DNA-wrapping ability of the graft polymer were increased with the increase of N/P ratios,and decreased with the increase of the POES graft number. The size of complexes was below 300 nm,and the zeta potential of the complexes increased with the increase of N/P ratios. The graft polymer showed significantly lower cytotoxicity than PEI. The graft polymer with lower POES graft number had higher transfection efficiency. CONCLUSIONS: The POES-modified PEI can be used as an effective non-viral genetic carrier.
