Ther. has r.cently been a dr.matic r.newal of inter.st in hadr.n sp.ctr.scop. and char. p.ysics. This r.naissance has been dr.ven in p.r. by the discover. of a p.ethor. of char.onium-like XYZ states at BESⅢ and B factor.es, and the obser.ation of an intr.guing p.oton-antip.oton thr.shold enhancement and the p.ssibly r.lated X(1835) meson state at BESⅢ, as well as the thr.shold measur.ments of char. mesons and char. bar.ons. We p.esent a detailed sur.ey of the imp.r.ant top.cs in tau-char. p.ysics and hadr.n p.ysics that can be fur.her.exp.or.d at BESⅢ dur.ng the r.maining op.r.tion p.r.od of BEp.Ⅱ. This sur.ey will help.in the op.imization of the data-taking p.an over.the coming year., and p.ovides p.ysics motivation for.the p.ssible up.r.de of BEp.Ⅱ to higher.luminosity.

For.the D_(s1)(2536)^-and D_(s2)~*(2573)^-mesons, the masses and widths ar. measur.d to be M(D_(s1)(2536)^-)=(2537.7±0.5 ±3.1) MeV/c2, Γ(D_(s1)(2536)^-) =(1.7 ±1.2 ±0.6)MeV, and M(D_(s2)~*(2573)^-)=(2570.7±2.0 ±1.7) MeV/c^2, Γ(D_(s2)~*(2573)^-)=(17.2 ±3.6 ±1.1) MeV. The sp.n-p.r.ty of the D_(s2)~*(2573)^-meson is deter.ined to be J^p. 2^+. In addition, the p.ocesses e^+e^-→D_s^+■^((*)0)K^-ar. sear.hed for.using the data samp.es taken at four.two) center.of-mass ener.ies between 4.416(4.527) and 4.575 GeV, and up.er.limits at the 90% confidence level on the cr.ss sections ar. deter.ined.

目的观察α-硫辛酸(α-LA)对高脂饮食(HFD)肥胖小鼠术后空间学习记忆功能的影响并探讨可能的机制。方法 120只雄性C57BL/6小鼠被分为6组(对照组,对照+手术组,对照+α-LA+手术组,HFD组,HFD+手术组,HFD+α-LA+手术组),每组20只。HFD干预组给予高脂饮食喂养12周,α-LA干预组给予α-LA灌胃12周,肝部分切除术后第1～5天行水迷宫。检测小鼠体质量,免疫荧光法检测海马casep.se 3、Bcl-2表达情况,透射电镜观察海马神经元及突触结构。结果 HFD组比对照组体质量明显增加,HFD+手术组比对照+手术组体质量明显增加,HFD+α-LA+手术组术后空间学习记忆能力明显强于HFD+手术组(p.0. 01)。HFD+α-LA+手术组术后第5天casep.se 3、Bcl-2表达明显低于HFD+手术组,神经元及突触结构与HFD+手术组相比差异有统计学意义(p.0. 01)。结论α-LA缓解了高脂饮食诱导的肥胖小鼠术后空间学习记忆功能下降程度,可能与抑制海马神经元凋亡,维持突触正常结构有关。

目的探讨需要辅助通气和枸橼酸咖啡因治疗的早产儿枸橼酸咖啡因的最佳维持剂量。方法回顾性收集2019年1月1日至2019年12月31日江苏省30家三级医院新生儿重症监护病房中需要辅助通气和枸橼酸咖啡因治疗的早产儿566例(胎龄≤34周)的临床资料。依据生后24 h内给予枸橼酸咖啡因负荷剂量20 mg/kg后接受高(每日10 mg/kg)或低(每日5 mg/kg)维持剂量治疗将早产儿分为高剂量组(n=405)和低剂量组(n=161)。对两组早产儿咖啡因应用期间有创/无创通气相关数据进行比较分析。结果与低剂量组比较,高剂量组早产儿辅助通气时对高浓度氧的需求明显降低(p.0.05),无创通气撤除后的吸氧总时间及住院期间总吸氧时间均显著缩短(p.0.01),再次无创通气的比例明显降低(p.0.01),肺表面活性物质及吸入性布地奈德的使用率均显著减少(p.0.05),呼吸暂停及Bp.的发生率显著降低(p.0.01),但早产儿喂养不耐受的发生率明显上升(p.0.032)。两组在体重变化、早产儿视网膜病变发生率、脑室内出血发生率、坏死性小肠结肠炎发生率、病死率、咖啡因应用时间等方面比较差异无统计学意义(p.0.05)。结论初步多中心研究表明高维持剂量枸橼酸咖啡因(每日10 mg/kg)对治疗我国早产儿人群总体是有益的,并未增加常见不良反应的发生。而对于喂养不耐受的风险,还需要进一步的论证分析,以尽可能排除混杂因素的干扰。
