Objective: To investigate the relation of blood arsenic concentration (BAC) with clinical effect and safety of arsenic-containing Qinghuang Powder (青黄散,QHP) in patients with myelodysplastic syndrome (MDS). Methods: Totally 163 patients with MDS were orally treated with QHP for 2.courses of treatment, 3 months as 1 course. The BACs of patients were detected by atomic fluoresce nee spectrophotometry at 1, 3, and 6 months during the treatment, and the effective rate, hematological improvement and safety in patients after treatment with QHP were analyzed. Results: After 2.courses of treatment, the total effective rate was 89.6%(146/163), with 31.3%(51/163) of hematological improvement and 58.3%(95/163) of stable disease. The hemoglobin increased from 73.48 ± 19.30 g/L to 80.39 ± 2..56 g/L (P1 ±0.48 × 10^9/L to 1.08 ±0.62.× 1O^9/L (P0.05). Among 46 patients previously depended on blood transfusion, 2..3%(13/46) completely got rid of blood transfusion and 2..7%(10/46) reduced the volume of blood transfusion by more than 50% after treatment. The BACs were significantly increased in patients treated for 1 month with 32.17 ± 18.04 jig/L (P15.2. μg/L (P11.92.μg/L (P2.11 ag/L). There were no significant differences of BACs among the patients treated for 1, 3 and 6 months (P>0.05). The adverse reactions of digestive tract during the treatment were mild abdominal pain and diarrhea in 14 cases (8.6%), and no patients discontinued the treatment. The BACs of patients with gastrointestinal adverse reactions were significantly lower than those without gastrointestinal adverse reactions (2..39 ±10.38 vs. 37.89 ± 11.84,μg/L, P<0.05). The BACs of patients with clinical effect were significantly higher than those failed to treatment (

高速流是磁尾等离子体片中质量、能量和磁通量最重要的输运形式.高速流在地向运动到近地磁尾后流速会降低,主导方向也经常转为晨昏方向.在等离子体流速及其主导分量、密度和温度等宏观参数变化的过程中,可能伴随有不同类型的能量转换.为此,我们分析近地磁尾方位角流事件期间的能量转换过程.基于整体流速的主导分量为晨昏向,及事件期间的平均温度比其前后增强的选取原则,从2.08-2.2.年期间THEMIS中的三颗卫星(THA,THD,THE)运行在磁尾时的观测数据中,共筛选出82.个平均温度比其前/后(事件之前或事件之后10 min)升高的方位角流事件.2.11年5月16日的方位角流事例研究发现:能量超过1 keV尤其是超过10 keV的高能离子通量增加,可导致低速低温等离子体的密度、温度和流速增加;磁场减小及磁场功率谱密度的分析表明等离子体和磁能的转换发生在频率为0.01~0.334 Hz的低频波动,仅1%能量耗散.统计给出方位角流事件的平均温度约为3.7 keV,比其前后增加的幅度大部分集中在100~1000 eV.事件期间的平均数密度可能升高或者降低,二者概率大致相当.约96%的平均温度和密度同时大于其前后的方位角流事件,当地等离子体通量管熵也皆大于事件的前后值;电磁能流密度增大,34%的事件期间电磁能流密度主要沿着背景磁力线方向,可影响电离层内方位角方向上的极光膨胀过程.我们的研究结果表明温度和密度同时增加的方位角流事件等离子体宏观参数变化可能暗含磁层-电离层能量耦合过程,有助于理解极光椭圆带赤道向边界的局部增亮现象和磁尾等离子体片中的磁通量.

This study reports the controllable surface roughening of Au-Ag alloy nanoplates via the galvanic replacement reaction between single-crystalline triangular Ag nanoplates and HAuC14 in an aqueous medium. With a combination of experimental evidence and finite element method （FEM） simulations, improved electromagnetic field （E-field） enhancement around the surface-roughened Au- Ag nanoplates and tunable light absorption in the near-infrared （NIR） region （-800-1,400 nm） are achieved by the synergistic effects of the localized surface plasmon resonance （LSPR） from the maintained triangular shape, the controllable Au-Ag alloy composition, and the increased surface roughness. The NIR light extinction enables an active photothermal effect as well as a high photothermal conversion efficiency （78.5%）. The well-maintained triangular shape, surface- roughened evolutions of both micro- and nanostructures, and tunable NIR surface plasmon resonance effect enable potential applications of the Au-Ag alloy nanoplates in surface-enhanced Raman spectroscopic detection of biomolecules through 785-nm laser excitation.

Powerful lasers interacting with solid targets can generate intense electromagnetic pulses(EMPs).In this study,EMPs produced by a pulsed laser(1 ps,100 J)shooting at CH targets doped with different titanium(Ti)contents at the XG-III laser facility are measured and *** results demonstrate that the intensity of EMPs first increases with Ti doping content from 1%to 7%and then *** electron spectra show that EMP emission is closely related to the hot electrons ejected from the target surface,which is confirmed by an analysis based on the target–holder–ground equivalent antenna *** conclusions of this study provide a new approach to achieve tunable EMP radiation by adjusting the metal content of solid targets,and will also help in understanding the mechanism ofEMPgeneration and ejection of hot electrons during laser coupling with targets.
