The novel CuO-SnO2 nanocomposite oxide photocatalysts were prepared by simple co-precipitation method, and characterized by X- ray diffraction, transmission electron microscopy, N2 adsorption-desorption measurement and UV-Vis diffuse reflectance spectroscopy. The photocatalytic activities of CuO-SnO2, evaluated using the photodegradation of Acid Blue 62 as a probe reaction under the irradiation of Xenon light, were also found to be related to the calcination temperature and the molar ratio of Cu to Sn. The maximum photocatalytic activity of the CuO-SnO2 photocatalyst was observed to be calcined at 500~C for 3 h （the molar ratio of Cu to Sn was 1：1） due to the sample with good crystallization and high surface area. It also showed much higher photocatalytic activity in treatment dye wastewater under simulated sunlight irradiation compared to Degussa P25 TiO2.

Based on a full vector-diffraction theory, a detailed theoretical study is carried out, aiming at providing a clear insight into the effects of different focusing and off-axis parabola parameters on far-field vector-diffraction properties of an offaxis parabolic mirror in the presence of misalignments of the incoming beam. The physical origin of these effects is also explored. The results show that the far-field intensity profile is altered by the distortion-, coma-, and astigmatism-like aberrations, which are caused by oblique incidence rather than inherent aberrations for the off-axis configuration. The radius of 90% encircled energy also increases but does not change monotonically with incident beam size increasing, or rather,it first decreases and then increases. The focal shift strongly depends on the effective focal length and oblique incidence angle, but it is almost independent of the beam size, which affects the focusing spot patterns. The intensity distribution produces a higher astigmatic image with off-axis angle increasing. Coma-like aberration starts to become dominant with beam size increasing and results in larger curved propagation trajectory. The incident polarization also affects the intensity distribution. The variation in the Strehl ratio with oblique incidence angle strongly depends on the misalignment direction and beam size as well. In addition, we find that the difference in locus between the catacaustic and the diffraction focus in the meridian is small. But the locus of the sagittal foci is obviously different from the locus of the meridian foci and the catacaustic focus. Moreover, the peak intensity of the sagittal focus is maximum, and the ratio of the peak intensity to that in the meridian plane is approximately 1.5. Understanding these effects is valuable for assessing a practical focused intensity and describing the motion of charged particles under a strong electric field in ultraintense laser–matter interaction.

The mechanism of the Richtmyer-Meshkov instability was experimentally studied in a vertical rectangular shock tube. The velocity of the interface driven by the shock wave was measured by a self-designed measurement system, which consists of semiconductor lasers, signal amplification circuits, digital oscilloscope and computer. Tests were carded out at several shock wave Mach numbers. In addition, the movement of the interface and the variation of the mixed zone width with time were recorded by high-speed photography. The experimental results show that the interface velocity increases with the increase of the Mach number, and the distance of the interface＇s movement and the width of the mixed zone vary with time in a linear relationship.

In this paper, we present a peculiar tripartite entangled state that is inequivalent to both the GHZ state and the W state, and then propose to implement efficient quantum information processing such as quantum dense coding and teleportation with this entangled state in cavity QED. In this scheme the atoms interact with a highly detuned cavity field with the assistance of a strong classical driven field. It does not require the transfer of quantum information between the atomic system and the cavity, and then our scheme is insensitive to both the cavity decay and the thermal field.

本试验旨在研究酶解羊毛粉(EWM)替代鱼粉并添加胆汁酸(BA)对大口黑鲈幼鱼生长性能及脂质代谢的影响。试验选择180尾大小均匀、初始体重为(10.00±0.02)g的大口黑鲈幼鱼,随机分为3组,每组3个重复,每个重复20尾鱼。对照组(CON组)饲喂以鱼粉和豆粕为蛋白质源的基础饲料,酶解羊毛粉组(EWM组)饲喂在基础饲料中用酶解羊毛粉替代25%鱼粉的试验饲料,酶解羊毛粉+胆汁酸组(EWM+BA组)饲喂在基础饲料中用酶解羊毛粉替代25%鱼粉并添加0.6 g/kg胆汁酸的试验饲料。试验期56 d。结果表明:1)EWM+BA组的末重(FBW)、增重率(WGR)、特定增长率(SGR)均显著高于CON组和EWM组(P<0.05)。2)EWM组的血清甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)含量和肝脏中总胆固醇(TC)、总胆汁酸(TBA)含量均显著高于CON组(P<0.05)。EWM+BA组的肝脏TG、TC、TBA含量和血清TBA含量均显著低于EWM组(P<0.05)。3)EWM组的肝脏乙酰辅酶A羧化酶1(ACC1)、脂肪酸结合蛋白(FABP)、硬脂酰辅酶A去饱和酶(SCD)、甘油三酯脂肪酶(ATGL)的mRNA相对表达水平显著高于CON组(P<0.05)。EWM+BA组的肝脏脂肪酸合成酶(FAS)、ACC1、SCD、固醇调节元件结合蛋白1(SREBP1)、过氧化物酶体增殖激活受体α(PPARα)、脂蛋白脂酶(LPL)和瘦素(LEP)的mRNA相对表达水平显著高于CON组和EWM组(P<0.05)。4)EWM组和EWM+BA组的肝脏法尼醇X受体(FXR)、类视黄醇X受体(RXR)的mRNA相对表达水平显著低于CON组(P<0.05)。EWM组的肝脏小异二聚体伴侣(SHP)的mRNA相对表达水平显著高于CON组和EWM+BA组(P<0.05)。EWM+BA组的肝脏胆固醇7α-羟化酶(CYP7A1)和成纤维细胞生长因子19(FGF19)的mRNA相对表达水平显著高于CON组和EWM组(P<0.05)。由此可见,酶解羊毛粉替代部分鱼粉并添加外源胆汁酸可缓解酶解羊毛粉对大口黑鲈的生长性能、脂质代谢和胆固醇代谢产生的不利影响。

Heat stress transcription factors (Hsfs) are the central regulators of defense response to heat stress. We identified a total of 25 rice Hsf genes by genome-wide analysis of rice (Oryza sativa L.) genome, including the subspecies of O. japonica and O. indica. Proteins encoded by OsHsfs were divided into three classes according to their structures. Digital Northern analysis showed that OsHsfs were expressed constitutively. The expressions of these OsHsfs in response to heat stress and oxidative stress differed among the members of the gene family. Promoter analysis identified a number of stress-related cis-elements in the promoter regions of these OsHsfs. No significant correlation, however, was found between the heat-shock responses of genes and their cis-elements. Overall, our results provide a foundation for future research of OsHsfs function.

目的观察加味金匮肾气丸预防单倍型异基因造血干细胞移植后出血性膀胱炎(HC)的临床疗效。方法对2020年1月至2023年10月接受单倍型异基因造血干细胞移植的65例血液病患者进行前瞻性队列研究,31例接受加味金匮肾气丸(5 g,每日2次口服)为肾气丸组,不接受肾气丸的34例为对照组。比较2组患者HC的累积发生率、临床特征及尿病毒检出率。中位随访时间为277(65,624)d。结果肾气丸组HC累积发生率为(29±3)%,对照组为(53±3)%,肾气丸组显著低于对照组(P0.05)。2组患者移植后尿液BK病毒(BKV)阳性率分别为42%和68%,肾气丸组显著低于对照组(P<0.05)。结论加味金匮肾气丸能够降低单倍型异基因造血干细胞移植后HC的累积发生率,可能与尿路BKV感染率降低有关。
