AIM： To identify possible differences of efficacy, safety predictability, higher-order aberrations and cornea biomechnical parameters after small-incision lenticule extraction（SMILE） and femtosecond lenticule extraction（FLEx）.· METHODS： A systematic literature retrieval was conducted in Medline,Embase and the Cochrane Library up to October, 2015. The included studies were subject to a Meta-analysis. Comparison between SMILE and FLEx was measured as pooled odds ratio（OR） or weighted mean differences（WMD）. Of 95% confidence intervals（CI） were used to analyze data.·RESULTS： A total of seven studies were included Firstly, there were no differences in uncorrected distance visual acuity（UDVA） 20/20 or better（OR, 1.37; 95% CI0.69 to 2.69; P =0.37） and log MAR UDVA（WMD,-0.02;95% CI,-0.05 to 0.01; P =0.17） after SMILE versus FLEx We found no differences in corrected distance visua acuity（CDVA） unchanged（OR, 0.98; 95% CI, 0.46 to 2.11;P =0.97） and log MAR CDVA（WMD,-0.00; 95% CI,-0.01 to 0.01; P =0.90） either. Secondly, we found no differences in refraction within ±1.00 D（OR, 0.98; 95% CI0.13 to 7.28; P =0.99） and ±0.50 D（OR, 1.62; 95% CI0.62 to 4.28; P =0.33） of target postoperatively. Thirdly for higher-order aberrations, we found no differences in the total higher-order aberrations（WMD,-0.04; 95%CI,-0.09 to 0.01;P =0.14）, coma（WMD,-0.04; 95% CI,-0.09 to 0.01; P =0.11）, spherical（WMD, 0.01; 95% CI,-0.02 to0.03; P =0.60） and trefoil（WMD,-0.00; 95% CI,-0.04 to0.03; P =0.76）. Furthermore, for corneal biomechanica parameters, we also found no differences（WMD, 0.08;95% CI,-0.17 to 0.33; P =0.54） after SMILE versus FLEx.·CONCLUSION： There are no statistically differences in efficacy, safety, predictability, higher-order aberrations and corneal biomechnical parameters postoperative between SMILE and FLEx.

目的:回顾分析超高度近视合并孔源性视网膜脱离(rhegmatogenous retinal detachment,RRD)的手术方式、手术效果、术后并发症及处理方法。方法:选择2011-01-01/2016-01-01于我院就诊的超高度近视合并RRD的患者47例47眼,并于我院行巩膜外加压术,玻璃体切除(pars plana vitrectomy,PPV)联合硅油填充术,或玻璃体腔注气术,回顾分析术后6mo内患者的BCVA、眼压、视网膜复位情况、裂孔闭合程度及术后并发症。结果:患者术后6mo时行PPV联合硅油填充的患者视力提高者24眼(71%);单纯行巩膜外加压术的患者视力提高8眼(73%)。统计学检验可见手术治疗能明显改善患者视力,尤其PPV联合硅油填充,但单纯行巩膜外加压术患者视力在本研究中经统计学检验显示无明显意义。PPV联合硅油填充的患者术后高眼压及复视等术后并发症较其他术式更多。结论:超高度近视合并孔源性视网膜脱离的患者需要及时行手术治疗,对术者临床经验及手术要求极高,需要术者根据视网膜裂孔的大小、位置及视网膜脱离范围选择不同的术式,及时恰当处理术后并发症,以争取患者术后裂孔最大程度的闭合、提高视网膜复位率及视功能,提高患者生活质量。

糖尿病视网膜病变(diabetic retinopathy,DR)是最常见的视网膜血管病,是50岁以上人群主要致盲眼病之一。DR早期微血管细胞受到损害,微血管扩张、渗漏,形成微血管瘤,随后微血管闭塞,形成无灌注区,最终视网膜缺血缺氧形成新生血管,进入糖尿病视网膜病变增殖期(proliferative diabetic retinopathy,PDR)。随着病情加重,将造成纤维血管膜的形成、视网膜前膜的纤维化加重,最终将造成牵拉性视网膜脱离。新近研究发现水通道蛋白1(aquaporin-1,AQP1)、水通道蛋白4(aquaporin-4,AQP4)在DR发生发展过程中起重要作用,导致视网膜内外屏障破坏,诱发视网膜水肿,参与新生血管形成,是视网膜新生血管形成过程中不可缺少的因子。

近视是生活中最常见的眼科疾病,它严重威胁着人们的眼部健康。目前,很多研究者应用光学相干断层成像(optical coherence tomography,OCT)以测量近视的视网膜结构变化,视网膜结构变化则是由屈光增加引起的眼轴增长导致的。另外,人们利用多焦视网膜电图进行视网膜功能的测量。全局闪光多焦视网膜电图(multifocal electroretinography,mf-ERG)可以同时测量视网膜内层和外层的功能。有些研究者在同一个研究中联合应用OCT和mf-ERG,以便于更好地了解近视引起的结构与功能变化的联系。我们需要更多的研究以了解二者之间的联系。

Magnetically tunable atom-exchange process involving ultracold weakly bound Feshbach molecules

引用

Science China(Physics,Mechanics & Astronomy) 2020年第5期63卷 31-38页

作者： jue nan Bo Zhao Hefei National Laboratory for Physical Sciences at Microscale and Deparment of Modern Physics University of Science and Technology of ChinaHefei 230026China Shanghai Branch CAS Center for Excellence and Synergetic Innovation Center in Quantum Information and Quantum PhysicsUniversity of Science and Technology of ChinaShanghai 201315China

Chemical reactions at ultracold temperatures have attracted great interest in recent years. The atom-exchange reaction between an atom and a weakly bound Feshbach molecule near overlapping Feshbach resonances presents a simple and ideal example of the controlled ultracold chemistry. The energy released in the reaction can be tuned to be very small and thus the reaction products can be trapped and detected, allowing the study of state-to-state reaction dynamics. The reaction can be tuned from the exothermic regime to the endothermic regime, which allows to study the threshold behavior of an endothermic reaction. In this paper, we review the recent progress in studying the atom-exchange reaction involving Feshbach molecules in ultracold atomic gases.

TRANSVERSAL INERTIAL EFFECT ON RELAXATION/RETARDATION TIME OF CEMENT MORTAR UNDER HARMONIC WAVE

引用

Acta Mechanica Solida Sinica 2008年第1期21卷 44-50页

作者： jue Zhu Yonghui cao Jiankang Chen Mechanics and Materials Science Research Center Ningbo University Ningbo 315211 China

Under dynamic loading, the constitutive relation of the cement mortar will be significantly affected by the transversal inertial effect of specimens with large diameters. In this paper, one-dimensional theoretical analysis is carried out to determine the transversal inertial effect on the relaxation/retardation time of the cement mortar under the harmonic wave. Relaxation time or retardation time is obtained by means of the wave velocity, attenuation coefficient and the frequency of the harmonic wave. Thus, the transversal inertial effect on the relaxation time from Maxwell model, as well as on retardation time from Voigt model is analyzed. The results show that the transversal inertial effect may lead to the increase of the relaxation time, but induce the decrease of the retardation time. Those should be taken into account when eliminating the transversal inertial effect in applications.

Testing the distance-duality relation with a combination of cosmological distance observations

引用

Research in Astronomy and Astrophysics 2011年第10期11卷 1199-1208页

作者： Shuo cao nan Liang Department of Astronomy Beijing Normal University Beijing 100875 China Center for High Energy Physics Peking University Beijing 100871 China

We propose an accurate test of the distance-duality （DD） relation, η = DL（z）（1 ＋ z）^-2/DA（z） = 1 （where DL and DA are the luminosity distances and angular diameter distances, respectively）, with a combination of cosmological observational data of Type Ia Supernovae （SNe Ia） from the Union2 set and the galaxy cluster sample under an assumption of the spherical model. In order to avoid bias brought on by redshift non-coincidence between observational data and to consider redshift error bars of both clusters and SNe Ia in the analysis, we carefully choose the SNe Ia points which have the minimum acceptable redshift difference of the galaxy cluster sample （│△Z│min = σz,SN ＋σz,cluster）. By assuming η to be a constant and defined as functions of the redshift parameterized by six different expressions, we find that there exists no observable evidence for variations in the DD relation based on the collected data, since related statistical tests are well satisfied within the 1σ confidence level for most cases. Further, considering different values of △z as constraints, we also find that the choice of △z may play an important role in this model-independent test of the DD relation for the spherical sample of galaxy clusters.

食品工业科技 2025年第1期46卷 87-96页

作者：黄素艳曹荣刘楠孙永周德庆王珊珊上海海洋大学食品学院上海201306 中国水产科学研究院黄海水产研究所山东青岛266071

以微拟球藻粉为原料,分别采用冻融盐析法、酶提辅助法和碱提酸沉法制备冻融蛋白(nannochloropsis freeze-thawed extraction protein,NFP)、酶提蛋白(nannochloropsis enzyme-assisted extraction protein,NEP)和碱提蛋白(nannochloropsis alkali extraction protein,NAP),并对其理化性质和功能特性进行对比分析。结果表明,碱提酸沉法的提取率为18.70%±0.50%,显著高于其他两种提取方式(P<0.05)。NFP、NEP与NAP中均含有多种人体必需氨基酸,分别占总氨基酸含量的38.75%、38.16%和37.88%;紫外吸收光谱显示三种提取蛋白在200~220 nm处有较强的吸光值;傅里叶变换红外光谱表明三种蛋白均具有典型的蛋白吸收峰,但二级结构发生变化,碱提处理使NAP中β-转角相对含量降低至19.62%±1.48%,β-折叠相对含量增加至32.90%±1.55%;与NEP和NFP相比,NAP的游离巯基含量和Zeta电位绝对值显著上升,粒径显著下降(P<0.05);扫描电镜显示不同提取方式下蛋白的显微结构有差异。功能特性分析显示三种蛋白的溶解性、起泡性及起泡稳定性随pH的变化趋势相似;相比NEP和NAP,NFP具有更好的功能特性。该研究结果为微藻蛋白资源在食品领域的开发利用提供了一定的理论依据。
