Objective To evaluate the effectiveness and safety of transcatheter closure of membranous ventricular septal defect (MVSD) using Amplatzer membranous VSD occluder (AMVSO). Methods The patients, who were clinically diagnosed with VSD were recommended for further transthoracic echocardiographic assessment using multiple standard views. If there were left to right shunts across ventricular septum, the margin of defects to the aortic valve was more than 1mm and that to tricuspid valve was more than 3 mm. If there was an aneurysm, it should not interfere with the function of outlet of right ventricule. Finally, if the diameter of VSDs wasless than 14mm, catheter closure of VSDs was suggested in these patients. The patients, having residual shunt after surgical closure of VSD, were included. All procedures were performed under local or general anesthesia. Transthorac echocardiography and X ray were used continuously to monitor the procedure. Transthoracic echocardiography was performed immediately after the release of devices, 24 hours, and 3 months after the procedure, respectively.Results From June 2002 to March 2003, 32 consecutive patients (15 females), underwent transcatheter closure of MVSD. The mean diameters of VSDs measured by echocardiography was 5.1 mm (3~8 mm) and, while that by angiography was 4.4 mm (3~8 mm). The mean size of the occluder was 7.6 mm(4~12 mm). The successful rate of device implantation was 100% (32/32). The residual shunt immediately after the closure was 11.5%, whereas after 24 hours it was only 7.7%, which was not serious. After 3 months′ follow-up, only 3.8% trivial residual shunt existed. No death occurred during and after the procedure. Atrial tachycardia, ventricular tachycardia, and bundle (right and left bundle) branch block, which was considered to relate to catheter manipulation inside the chamber of ventricle, were common and transient. One aortic regurgitation and tricuspid insufficiency became severe after the procedure, but they were not serious. One patient developed III degree A-V block 24 hours after the procedure, and EKG became LBBB 3 days after the temporary pace making. Hemolysis was observed in one patient, and he recovered 7days after the medication therapy. Conclusion Transthoracic echocardiography was very much effective in catheter closure of MVSD. The asymmetric self-expanding nitinol double-disc Amplatzer device designed for the transcatheter closure of MVSD is implanted easily and stably. Due to low ratio of residual shunt and few serious complications, the Amplatzer device is a good choice for the transcatheter closure of MVSD.

Objective To investigate the relationship between the maturity and function of dendritic cells (DC) and hepatitis B virus covalently closed circular DNA (HBV cccDNA) load in the peripheral blood mononuclear cells (PBMC)/monocyte-derived DC in patients with chronic hepatitis B (CHB). Methods The peripheral blood samples were collected from 29 patients with CHB and 10healthy controls. PBMC were isolated freshly and induced with granulocyte/macrophage colony stimulating factor (GM-CSF) and interleukin-4 (IL-4). A large amount of DC were harvested after seven days of culture. The expressions of CD209, CD80, CD86, human leucocyte antigen (HLA)-DR and CD1a of DC were analyzed by flow cytometry. The HBV cccDNA load in PBMC and DC were measured by real-time polymerase chain reaction (PCR). The interleukin-12 (IL-12) level in the culture supernatant of DC was determined by enzyme linked immunosorbent assay (ELISA). The effects on T lymphocyte proliferation induced by DC were tested by mixed lymphocyte reaction (MLR). The data was compared by t test and analysis of variance. Results HBV cccDNA could be detected in PBMC from 16 patients, but not in DC from all 29 patients. HBV cccDNA load was all negatively correlated with the expressions of CD209 (r= -0. 793, P<0.01), CD80 (r= -0. 581,P<0.05), CD86 (r=-0. 698, P<0.01), HLA-DR (r=-0. 817, P<0.01), CD1a (r=-0. 734, P<0.01), IL-12 level (r=-0. 632, P<0.05) and allogenic T lymphocyte proliferation induced by DC (r=-0. 617, P<0.05). The expressions of CD209, CD80, CD86, CD1a and HLA-DR on DC,IL-12 level in culture supernatant of DC and the allogenic T lymphocyte proliferation induced by DC in patients with positive PBMC HBV cccDNA were all significantly lower compared to those in healthy controls, and the changes of the parameters mentioned above were greater in PBMC HBV cccDNA positive patients than those in PBMC HBV cccDNA negative patients (P < 0. 05 or P < 0. 01).Conclusions The function and maturity of DC are impaired in CHB patients. HBV cccDNA can be detected in PBMC from CHB patients. Moreover, the higher PBMC HBV cccDNA is, the worse DC function and maturity are, which could be one of the important mechanisms of HBV persistent infection.
