目的评价腹部X线在检测体内非法藏毒中的诊断效能,以低剂量CT为参考标准。材料与方法本研究通过单位伦理委员会批准,并签署知情同意书。从2007年7月—2010年7月对怀疑吞入包装毒品的330人(男296人,女34人;年龄18～55岁,平均32岁)进行仰卧位腹部X线摄影和低剂量CT检查。报告腹部X线摄影是否发现体内毒品包,以低剂量CT为参考标准。记录低剂量CT中毒品包的密度和数量(≤12或>12),分析确定这些因素是否会对腹部X线的结果有影响。结果低剂量CT在53个(16%)嫌疑人的体内发现了毒品包。腹部X线摄影对于检测毒品包的敏感度是0.77(41/53),特异度是0.96(267/277)。53例毒品包中,低剂量CT发现16例(30%)与肠内容物呈等密度;19例(36%)的毒品包数量小于12个。低剂量CT中的等密度毒品包和较少的毒品包数量(≤12)均与腹部X线摄影的假阴性结果存在明显相关性(P值分别为0.004和0.016)。结论与低剂量CT相比,腹部X线摄影筛查体内藏毒嫌疑人的敏感度有限。低剂量CT是一种腹部X线摄影的有效替代方法。原文载于Radiology,2012,265(3):772-779.

The first search for the doubly heavyΩ^(0)_(bc)baryon and a search for the E^(0)_(bc)baryon are performed using pp collision data collected via the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb^(-1).The baryons are reconstructed via their decays to Λ^(+)_(c)π^(-)and E^(+)_(c)π^(-).No significant excess is fbund for invariant masses between 6700 and 7300 MeV/c^(2),in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** limits are set on the ratio of the Ω^(0)_(bc)and E^(0)_(bc)production cross-section times the branching fraction to Λ^(+)_(c)π^(-)(E^(+)_(c)π^(-))relative to that of the Λ^(0)_(b)(E^(0)_(b))baryon,for different lifetime hypotheses,at 95%confidence *** upper limits range from 0.5 x 10^(-4)to 2.5 x 10^(-4)for theΩ^(0)_(bc)→Λ^(+)_(c)π^(-)(E^(0)_(bc)→Λ^(+)_(c)π^(-))decay,and from 1.4x 10^(-3)to 6.9 x 10^(-3)for theΩ^(0)_(bc)→E^(+)_(c)π^(-)(E^(0)_(bc)→E^(+)_(c)π^(-))decay,depending on the considered mass and lifetime of theΩ^(0)_(bc)(E^(0)_(bc))baryon.

A search for the rare decay b^(0)→J/ψФis performed using Pp collision data collected with the LHCb dete-ctor at centre-of-mass energies of 7,8 and 13 TeV,corresponding to an integrated luminosity of9 *** significant signal of the decay is observed and an upper limitof 1.1x 10^(-7)at 90%confidence level is set on the branching fraction.

The cross sections of e^(+)e^(-)→K^(+)K^(-)J/Ψat center-of-mass energies from 4.127 to 4.600 GeV are measured based on 15.6 fb-1data collected with the bESⅢ detector operating at the bEPCⅡ storage *** resonant structures are observed in the line shape of the cross *** mass and width of the first structure are measured to be(4225.3±2.3±21.5)MeV and(72.9±6.1±30.8)MeV,*** are consistent with those of the established Y(4230).The second structure is observed for the first time with a statistical significance greater than 8σ,denoted as Y(4500).Its mass and width are determined to be(4484.7±13.3±24.1)MeV and(111.1±30.1±15.2)MeV,*** first presented uncertainties are statistical and the second ones are *** product of the electronic partial width with the decay branching fractionΓ(Y(4230)→e^(+)e^(−))b(Y(4230)→K^(+)K^(−)J/Ψ)is reported.
