A first search for the Ξ_(bc)^(+)J/ψΞ_(c)^(+) decay is performed by the LHcb experiment with a data sample of proton-proton collisions, corresponding to an integrated luminosity of 9 fb−1 recorded at centre-of-mass energies of 7, 8, and 13 TeV. Two peaking structures are seen with a local (global) significance of 4.3(2.8) and 4.1(2.4) standard deviations at masses of 6571 and 6694 MeV/c2, respectively. Upper limits are set on the Ξ+bc baryon production cross-section times the branching fraction relative to that of the B+c→J/ψD+s decay at centre-of-mass energies of 8 and 13 TeV, in the Ξ+bc and in the B+c rapidity and transverse-momentum ranges from 2.0 to 4.5 and 0 to 20GeV/c, respectively. Upper limits are presented as a function of the Ξ+bc mass and lifetime.

目的评价局部晚期乳腺癌(LABc)f-脱氧葡萄糖(fDG)PET/cT显像的纹理分析参数在疗效和预后预测中的价值。方法该前瞻性研究包括68例LABc患者,纳入者均有新辅助化疗(nc)指征,并在化疗前行f-fDG PET/cT显像。对乳腺癌穿刺标本依据分子表型进行分组[雌激素受体(ER)、孕激素受体(PR)及人表皮生长因子2(HER2)的表达、细胞增殖核抗原Ki-67指数等)],并在nc结束后将患者分为有效组和无效组。所有患者经标准的随访后得到无病生存时间(DfS)和总生存时间(OS)。利用计算机软件对乳腺癌病灶进行三维(3D)图像分割,随后进行纹理特征分析,获得行程长度矩阵(RLM)和共生矩阵(cM)参数。对不同危险度的纹理特征与各种分子表型的关系进行分析。使用Kaplan-Meier生存分析和cox比例风险分析对纹理参数、分子表型和nc的肿瘤组织学反应等在预测疗效和预后中的作用进行研究。通过受试者工作特征(ROc)曲线分析取得最佳截断值、曲线下面积(AUc)及与OS、DfS相关的灵敏度和特异性。结果 nc对18例患者有效,其DfS和OS分别为(70.87±21.85)个月和(76.77±18.80)个月。长行程增强(LRE)和长行程高灰阶增强(LRHGE)与不同的危险度分层有关,而低灰阶行程增强(LGRE)、LRHGE和行程长度不均匀性(RLnU)均与nc的疗效相关。单因素分析结果表明纹理特征分析各变量与OS和DfS相关。多因素cox回归分析结果显示,短行程高灰阶强化(SRHGE)下的PET分期与OS相关,而PET分期、高灰阶行程强化(HGRE)均与DfS相关。结论f-fDG PET/cT图像的纹理特征分析各变量可预测新辅助化疗的疗效和预后,并在预测OS和DfS时与PET分期具有相关性。
