Background The Syntax score was recently developed as a comprehensive, angiographic tool grading the complexity of coronary artery disease （CAD）. It aims to assist in patient selection and risk stratification of patients with extensive CAD undergoing revascularization. However, the prognostic value of the Syntax score in patients undergoing percutaneous coronary intervention （PCI） has not been validated. The aim of this study was to evaluate its role in predicting long-term incidences of major adverse cardiac and cerebrovascular events （MACCE） in patients undergoing PCI for 3-vessel *** Two hundred and three consecutive patients with de novo 3-vessel CAD undergoing PCI with sirolimus-eluting stents were studied. Their angiograms were scored according to the Syntax score. The patients were divided into tertiles according to the Syntax score： lowest Syntax score tertile （Syntax score 〈22）, intermediate Syntax score tertile （Syntax score of 23 to 32）, and the highest Syntax score tertile （Syntax score 〉33）. During the 1-year follow-up, the MACCE-free survival curves were estimated by the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relation between the Syntax score and the incidence of MACCE. Performance of the Syntax score was studied with respect to predicting the rate of MACCE by receiver operator characteristic （ROC） curves with an area under the *** The overall Syntax score ranged from 6 to 66 with mean ± standard deviation of 27.9±12.6 and a median of 26. At 1 year, the Syntax score significantly predicted the risk of MACCE （HR 1.07/U increase, 95% Cl 1.04 to 1.11, P 〈0.001）. The rate of MACCE was significantly increased among patients in the highest Syntax score tertile （17.9%） as compared with those with the lowest Syntax score tertile （1.4%, P 〈0.001） or intermediate Syntax score tertile （6.2%, P=0.041）.

Chinese Medical Journal 2016年第7期129卷 763-770页

Background： There are limited data on longer-term outcomes （〉5 years） for patients with unprotected left main coronary artery （ULMCA） disease who underwent percutaneous coronary intervention （PCI） in the drug-eluting stents （DES） era. This study aimed at comparing the long-term （〉5 years） outcomes of patients with ULMCA disease underwent PCI with DES and coronary artery bypass grafting （CABG） and the predictors of adverse events. Methods： All consecutive patients with ULMCA disease treated with DES implantation versus CABG in our center, between January 2003 and July 2009, were screened for analyzing. A propensity score analysis was carried out to adjust for potential confounding between the two groups. Results： Nine hundred and twenty-two patients with ULMCA disease were enrolled for the analyses （DES = 465 vs. CABG = 457）. During the median follow-up of 7.1 years （interquartile range 5.3-8.2 years）, no difference was found between PCI and CABG in the occurrence of death （P = 0.282） and the composite endpoint of cardiac death, myocardial infarction （MI） and stroke （P = 0.294）. Rates of major adverse cardiac and cerebrovascular events were significantly higher in the PCI group （P = 0.014） in large part because of the significantly higher rate of repeat revascularization （P 〈 0.001）. PC/was correlated with the lower occurrence of stroke （P = 0.004）. Multivariate analysis showed ejection fraction （EF）（P = 0.012）, creatinine （P = 0.016）, and prior stroke （P = 0.03 l） were independent predictors of the composite endpoint of cardiac death, MI, and stroke in the DES group, while age （P = 0.026） and EF （P = 0.002） were independent predictors in the CABG group. Conclusions： During a median follow-up of 7.1 years, there was no difference in the rate of death between PCI with DES implantation and CABG in ULMCA lesions in the patient cohort. CABG group was observed to have significantly lower rates of repeat revascularization but higher stroke rates compared with PCI. EF, cre

The ^(232)Th(n,f)cross section is very important in basic nuclear physics and applications based on the Th/U fuel *** the time-of-flight method and a multi-cell fast-fission ionization chamber,a novel measurement of the^(232)Th(n,f)cross sec-tion relative to^(235)U in the 1–200 MeV range was performed at the China Spallation Neutron Source Back-n white neutron source(Back-n).The fission event-neutron energy spectra of^(232)Th and^(235)U fission cells were measured in the single-bunch *** 232Th/235U fission cross-sectional ratios were obtained,and the measurement uncertainties were 2.5–3.7%for energies in the 2–20 MeV range and 3.6–6.2%for energies in the 20–200 MeV ***^(232)Th(n,f)cross section was obtained by introducing the standard cross section of^(235)U(n,f).The results were compared with those of previous theoreti-cal calculations,measurements,and *** measured 232Th fission cross section agreed with the main evaluation results in terms of the experimental uncertainty,and 232Th fission resonances were observed in the 1–3 MeV *** present results provide^(232)Th(n,f)cross-sectional data for the evaluation and design of Th/U cycle nuclear systems.

Back-streaming neutrons from the spallation target of the China Spallation Neutron Source(CSNS)that emit through the incoming proton channel were exploited to build a white neutron beam facility(the so-called Back-n white neutron source),which was completed in March *** Back-n neutron beam is very intense,at approximately 29107 n/cm2/s at 55 m from the target,and has a nominal proton beam with a power of 100 kW in the CSNS-I phase and a kinetic energy of 1.6 GeV and a thick tungsten target in multiple slices with modest moderation from the cooling water through the *** addition,the excellent energy spectrum spanning from 0.5 eV to 200 MeV,and a good time resolution related tothe time-of-flight measurements make it a typical white neutron source for nuclear data measurements;its overall performance is among that of the best white neutron sources in the *** with advanced spectrometers,detectors,and application utilities,the Back-n facility can serve wide applications,with a focus on neutron-induced cross-sectional *** article presents an overview of the neutron beam characteristics,the experimental setups,and the ongoing applications at Backn.
