Objective To compare the short- and long-term clinical outcomes between sirolimus-eluting stent （ Cypher stent） and paclitaxel-eluting stent （TAXUS stent） in patients with in-stent restenosis （ISR） lesions of the coronary arteries. Methods From December 2002 to March 2005, 253 patients with ISR lesions of the coronary arteries were selected and divided into two groups. Cypher group （152 cases） was treated with Cypher or Cypher Select stents, and TAXUS group （101 cases） with TAXUS stents. A total of 262 ISR lesions in these patients were treated with 308 drog-eluring stents （DESs）, including 176 Cypher or Cypher Select stents and 132 TAXUS stents. All patients were followed up for 10 months. Procedure success rates of DES implantation in both groups were observed. Major adverse cardiac events （MACE） rates in hospital and at 10 months follow-up, as well as in-DES restenosis observed using coronary angiography at follow-up were compared between two groups. Results Success rate of DES implantation was 100% in both groups. No significant difference in MACE rate during hospitalization was found between the two groups. However, at 10 months follow-up, MACE rate was higher in TAXUS group than in Cypher group （ 16.00% vs. 6.67%, P =0. 031 ）. As for coronary angiography at 10 months follow-up, we observed an increasing tendency of in-DES restenosis rate in TAXUS group compared with Cypher group （29.41% vs. 14.04%, P=0.075）. Conclusions Cypher and TAXUS DESs both have good short- and long-term outcomes in treating ISR. Cypher DES proved better long-term clinical outcome than TAXUS DES.

To verify the performance of the neutron total cross-sectional spectrometer, the neutron total cross section of carbon is initially measured in the energy range of 1 eV to 20 MeV using the time-of-flight method. The measurement is performed at the Back-n white neutron source with a 76-m time-of-flight path using the China Spallation Neutron Source. A multilayer fast fission chamber with 235U and 238U is employed as the neutron detector. The diameter and thickness of the natural graphite sample are 70 mm and 40 mm, respectively. Signal waveforms are collected using a data acquisition system. Off-line data processing was used to obtain the neutron time-of-flight spectra and transmissions. The uncertainty of the counting statistics is generally approximately 3% for each bin in the energy range of 1–20 MeV. It is determined that the results for the neutron total cross section of carbon obtained using ^235U cells are in good agreement with the results obtained using 238U cells within limits of statistical uncertainty. Moreover, the measured total cross sections show good agreement with the broadening evaluated data.

Background Drug-eluting stent （DES） could obviously reduce in-stent restenosis, which has been proved by international multi-center clinical trials. However, the types of the lesions for stenting were highly selected in these trials. Up to now, there has been no large scale study on the effect of DES in treating complex lesions in real world. Although REALITY trial was just reported during American College of Cardiology Congress 2005, the entry criteria for lesions were limited to one or two de novo lesions. This study was conducted to compare the short- and mid-term clinical outcomes between sirolimus-eluting stent （CYPHER stent） and paclitaxel-eluting stent （TAXUS stent） in patients with complex lesion. Methods This is a retrospective study. From April 2002 to June 2004, a total of 1061 patients were treated with DES in Fu Wai Hospital, of which, 611 patients （642 lesions with 698 CYPHER stents） were in CYPHER group, and 450 patients （534 lesions with 600 TAXUS stents） were in TAXUS group. There was no significant difference in clinical data and lesion types between CYPHER group and TAXUS group. Results Success rates of stent implantation were 99.2% and 98.8% in CYPHER and TAXUS stent groups respectively. The major adverse cardiac events （MACE） during in-hospital and 6-8-month follow-up were 0.7% and 2.3% in CYPHER stent group versus 1.3% and 3.2% in TAXUS stent group. There was no significant difference in MACE rate between these two groups. Restenosis rate was a little higher in TAXUS stent group than that in CYPHER stent group （14.0% vs 7.3%）, but there was no significant difference. The incidence of acute occlusion of side branch after implanting DES in main vessel was 6.9% in CYPHER group and 11.9% in TAXUS group （P〈0.05） . Conclusions CYPHER and TAXUS DES were safe and effective in patients with complex lesion. Clinical outcomes of CYPHER stent were better than TAXUS stent in bifurcation lesions. There was an increasing tendency in restenosis rate and la

Background Surgical aortic valve replacement is the standard treatment for patients with severe aortic stenosis, but some registries have indicated that 30% to 60% of these patients are not treated surgically, usually due to advanced age and/or comorbidities. This single center study in China investigated the current treatment status in the patients with severe aortic stenosis and evaluated the long term clinical outcome in advanced age patients whether or not undergoing aortic valve replacement. Methods Clinical data of 867 consecutive patients with severe aortic stenosis between January 2000 and December 2006 were retrospectively analyzed. The patients 〉65 years old were followed up by telephone or information from medical records. The primary end-point was all-cause mortality. Results The patients＇ average age was （52±19） years （range, 1-91 years）, and 34% were women. The percentages of the patients aged 〈15 years, between 15 and 34 years, between 35 and 54 years, between 55 and 64 years, between 65 and 74 years, and 〉75 years who underwent surgical aortic valve replacement were 82.3%, 87.2%, 88.8%, 78.2%, 65.3% and 22.2% respectively. In the patients （n=256）〉65 years old, 43.4% had New York Heart Association class III and IV symptoms, 39.1% had hypertension, 33.2% had coronary heart disease, and 3.1% had stroke. In the patients not undergoing aortic valve replacement, 1.6% had renal insufficiency, 4.7% had chronic obstructive pulmonary disease, 2.0% had critical hematopathy, and 0.4% had mammary cancer. A total of 186 （72.7%） patients finished the follow-up, and the average duration of the follow-up was （60±2.6） months. In the patients between 65 and 74 years old, the total deaths and cardiac deaths in the patients undergoing aortic valve replacement decreased significantly compared with those with conservative treatment （10.3% vs. 53.7%, P 〈0.001 and 6.3% vs. 50.7%, P〈0.001）. Similarly, in the patients ≥75 years old, there was a significant difference between

Background A comparison of efficacy and safety between transradial and transfemoral approach for percutaneous coronary intervention （PCI） in bifurcations has not been done. This study evaluated feasibility of transradial PCI （TRI） and compared the immediate and followup results with transfemoral PCI （TFI） in bifurcations. Methods One hundred and thirty-four consecutive patients with bifurcations were treated with PCI in our hospital from April 2004 to October 2005. Of these, there were 60 patients （88 lesions） in TRI group and 74 patients （101 lesions） in TFI group. Bifurcations type was classified according to the Institut Cardiovasculaire Paris Sud Classification. Results TRI group had smaller stent diameter （（3.06±0.37） mm vs （3.18±0.35） mm, P=0.023） and postprocedural in-stent minimum lumen diameter （（2.62±0.37） mm vs （2.74±0.41） mm, P=0.029） than TFI, but there were not significant differences in in-stent subacute thrombosis rate （0% vs 1.0%, P=0.349）, target lesion revascularization （TLR）（0% vs 1.0%, P=0.349） following procedure and thrombosis （2.3% vs 1.0%, P=0.482）, in-stent restenosis （12.5% vs 10.9%, P=0.731）, in-segment restenosis （17.0% vs 14.9%, P=0.681）, TLR （10.2% vs 13.9%, P=0.446） and TLR-free cumulative survival rate （89.8% vs 86.1%, P=0.787） at seven months followup. No death was reported in the two groups. Conclusion Transradial intervention is feasible and appears to be as effective and safe as transfemoral PCI in treatment of true bifurcational lesions.
