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.

背景与目的脂肪来源干细胞（adipose-derived stem cells，ADSCs）已成为研究最多的成体干细胞。笔者对人类脂肪组织抽吸物中脂肪细胞、血管间质成分（stromal vascular fraction，SvF）和ADSCs凋亡和坏死进行分析。方法通过标准的吸脂术获取人类脂肪抽吸物（n=8）。将SvF从脂肪细胞中分离出来，并通过培养纯化ADSCs。通过一组干细胞标记物来确认培养的ADSCs的表面表型。从SvF中可分离出3种干细胞亚群（CD90^＋／CIM5^-，CDl05^＋／CD45^-及CD34^＋／CD31^-）。利用流式细胞术分析，通过膜联蛋白v／碘化丙啶检验确定细胞凋亡和细胞死亡。结果由倍增时间以及油红O染色和碱性磷酸酶染色均为阳性证明，培养的ADSCs具有长期增殖和分化的能力。从脂肪抽吸物中获取的各部分细胞中，脂肪细胞出现（19．7±3．7）％凋亡和（1．1±0．3）％坏死；SvF（22．0±6．3）％凋亡和（11．2±1．9）％坏死；SvF的坏死率较脂肪细胞高（P〈0．05）。在SvF细胞中，（51．1±3．7）％细胞表达CD90^＋／CD45^-，（7．5±1．0）％细胞表达CDl05^＋／CD45^-，而（26．4±3．8）％细胞表达CD34^＋／CD31^-。表达CD34^＋／CD31^-与表达CDl05^＋／CD45^-的ADSCs相比，其细胞凋亡和细胞坏死的概率均较低（P〈0．05）。结论与脂肪细胞相比，ADSCs有较高的细胞凋亡和细胞坏死发生概率。而在ADSCs亚群之间，细胞凋亡和细胞坏死的程度也明显不同。

維持性血液透析患者透析充分性相關因素分析

目的探討影響維持性血液透析充分性的相關因素,為臨床護理提供依據。方法回顧性分析患者的透析充分性指標單室尿素清除指數(single pool KT/v SPKT/v)、尿素清除率(urea clearance rate,URR)與透析中超濾量、乾體重、血流量、血紅蛋白等的相關性。選擇2016年7月~2017年3月在本院維持性血液透析的患者60例為研究對象,每個月監測血紅蛋白、肌酐、尿素等10項指標,從His系統中得到至少用同一種機型的7次SPKT/v和URR值,將每人最低一次和最高一次SPKT/v作自身對比,用統計學方法分析探討影響透析充分性的相關因素。結果血紅蛋白與透析充分性呈負相關,血流量與透析充分性呈正相關。結論透析充分性與患者血流量、血紅蛋白等密切相關,提示我們在護理工作中要密切觀察和保證患者的血流量;在病人健康教育方面,強調加強營養的重要性,但也要避免血紅蛋白過高,造成血透時紅細胞在透析器裡蓄積,影響對毒素的清除效果。
