遗传性耳聋是一种常见的遗传性疾病,新生儿的发病率为1‰~3‰。患者终身携带致病突变,导致不可逆性耳聋,至今尚无临床可用的治疗药物。在部分遗传性耳聋动物模型中,基因治疗已被证实为潜在有效的治疗方法。国内外已开展了多项遗传性耳聋基因治疗的临床试验。其中,由东南大学附属中大医院牵头,联合国内多家医院成功开展的遗传性耳聋基因治疗临床试验,取得了显著的疗效,并积累了丰富的经验。为规范遗传性耳聋基因治疗并提供临床研究指导,全国多家医院的耳科专家讨论制定了遗传性耳聋基因治疗临床指南,内容涵盖了伦理审查、遗传性耳聋的诊断和入组标准、临床前准备、药物、疗效与安全性评估标准、术后言语康复等。本指南将为耳聋基因治疗的临床诊疗提供规范的理论和技术指导。

目的:在全国范围内调查机械通气危重症病人EN和PN支持现状和存在问题,为进一步改进危重症病人营养支持策略提供临床依据。方法:国内多中心、前瞻性和观察性研究。本次调查历时100 d,共有15个省市、25所医院、26个ICU共443例病人参与。依据加拿大Heyland研究小组发起的2008年全球ICU危重症病人营养支持应用现状调查的内容,对所得结果进行独立统计学分析。结果:19个ICU(73%)对病人EN期间床头抬高、胃残余量监测、中止喂养或转为小肠喂养指征等具体实施细则有明确的规定。25个ICU(96.2%)有计划应用胰岛素控制病人血糖。早期(入住ICU48 h内)TEN病人仅占38.8%(172/443);EN+PN占20.5%(91/443);因不耐受EN而中途中止的病人共10例(5.8%)。本次调查共观察4 303 d。2 003 d(46.5%)接受TEN,869 d接受EN+PN(20.2%)。72 h内达到80%预计能量病人共82例(47.7%),与未达预计能量病人相比,机械通气时间、入住ICU时间、住院时间和病死率均无显著性差异。接受PN病人共230例,经PN液中添加Gln者占38.3%(88/230);机械通气时间(P=0.001)和入住ICU时间(P=0.005)明显少于未添加Gln组。结论:危重症病人营养支持已得到广泛认可和重视,并通过具体的实施方案规范临床行为。EN仍存在喂养不足和累积能量摄入的缺乏。PN液中添加Gln能缩短病人机械通气和入住ICU的时间。

To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha scattering events, we measure the integrated luminosity of the data sample at each center-of-mass energy point. The total integrated luminosity of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical and the second systematic.

There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESⅢ and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BESⅢ, as well as the threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESⅢ during the remaining operation period of BEPCⅡ. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BEPCⅡ to higher luminosity.

Studies of e^+e~→D_s^+■^((*)0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb^(-1) collected with the BESIII detector at s^(1/2)=4.600 GeV. The processes of e^+e^-→D_s^+■^(*0)K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+D_(s1)(2536)^-and D_s^+D_(s2)~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■^(*0)K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+D_(s1)(2536)^-+c.c.)·B(D_(s1)(2536)^-→■^(*0)K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+D_(s2)~*(2573)^-+ c.c.)·B(D_(s2)~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the D_(s1)(2536)^-and D_(s2)~*(2573)^-mesons, the masses and widths are measured 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 spin-parity of the D_(s2)~*(2573)^-meson is determined to be J^p= 2^+. In addition, the processes e^+e^-→D_s^+■^((*)0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 GeV, and upper limits at the 90% confidence level on the cross sections are determined.
