As part of ongoing environmental investigations of U mining impacts, forty-two sediment samples of a nearly-half-meter-long sediment core retrieved from a natural reservoir near an active uranium (U) mining site, South China were analyzed to quantify the extent of U release and identify U release mechanism within the riverine catchment. Enrichment levels of U was dispersed not only in the surface sediments but also in deep sediments across the depth profile. Further analysis by SEM-EDS and XRD indicated that U partitioning in the depth profile was possibly controlled by complicated interplay of leaching and precipitation cycles of U-bearing minerals. Even with the relative complexity of U dispersal processes within the catchment, the Pb isotopic fingerprinting techniques allowed quantification of source inputs of the sediments by using a binary mixing model. The results revealed that along the depth profile, only 6%-50% of the sediment material is anthropogenically derived from the U ore tailing, with the other predominant proportions originated from geogenically natural weathering of granitic bedrocks. This study highlights the use of Pb isotopes as a powerful tool for quantitatively fingerprinting the sources of U dispersal in the sediment core, and natural-occurring U contamination that may become a hidden geoenvironmental health hazard in this area.

Two new baccharane-type glycosides（1 and 2）, together with seven known baccharane-type glycosides （3u9） hosenkoside A, hosenkoside B, hosenkoside C, hosenkoside F, hosenkoside M, hosenkoside K and hosenko- side G were isolated from the dried seeds of Impatientis balsamina L. The new baccharane-type glycosides were identified as honsenkol A-3-O-β-D-glucopyranosyl-26-O-p-D-glucopyranosyl-28-O-β-D-glucopyranosyl-O-β-D- glucopyranosyl（1） and （3S,4R,17R,20S）17-hydrroxy-3-O-β-D-xylopyranose（12）-β-D-glucopyranosyl-26-O-β-D- glucopyranosyl-28-O-β-D-glucopyranosyl-21,24-epoxybaccharane（2）, respectively, by spectroscopic methods, in- cluding NMR（1D and 2D）, IR and HR-ESI-MS. Compounds 1 and 2 were evaluated for in vitro inhibitory activity against the cell lines. Compound 2 with a new baccharane skeleton had anti-hepatic fibrosis activity against A375 cells in bioassay results, which means the new compounds have potential value in antitumor applications.

High contamination risks of thallium and associated metal(loid)s in fluvial sediments from a steel-making area and implications for environmental management

Thallium (Tl) is an uncommon toxic element, with an even greater toxicity than that of As, Hg and Cd. Steel-making industry has been identified as an emerging new significant source of Tl contamination in China. This paper presents a pilot investigation of the contamination and geochemical transfer of Tl and associated metal (loid)s in river sediments affected by long-term waste discharge from the steel-making industry. The results uncovered an overall Tl contamination (1.96 +/- 0.42 mg/kg) across a sediment profile of approximately 1.5 m in length, even 10 km downstream the steel plant. Highly elevated contents of Pb, Cu, Cd, Zn and Sb were found in the fluvial sediments, displaying strong positive correlations with Tl contents. Elevated levels of geochemically mobile Tl as well as Cd, Zn, Cu and Pb occurred in the fluvial sediments, signifying anthropogenic imprints from steel production activities at high temperature. Levels of contamination and ecological risk were calculated to be moderate to considerable for Tl, Cu, Zn and high to very high for Cd, Pb, Sb. The results highlight that there is a great challenge in view of potentially considerable Tl pollution due to continuous massive steel production in many other parts of China. It is high time to initiate process-based management of Tl contamination control for the ambient aquifer system in the steel-making area.

目的探讨非体外循环下冠状动脉搭桥术(off-pump coronary artery bypass,OPCAB)患者Th1/Th2和Th17/Treg平衡的变化。方法以40例冠状动脉旁路移植术患者为研究对象。分别于麻醉前(T0)、切皮即刻(T1)、给肝素后5 min(T2)、给鱼精蛋白后5 min(T3)、手术结束时(T4)、术后1天(T5)、术后2天(T6)采血,测定肿瘤坏死因子-α(TNF-α)、干扰素-γ(IFN-γ)、白细胞介素-2(IL-2)、白细胞介素-4(IL-4)、白细胞介素-6(IL-6)、白细胞介素-10(IL-10)、调节性生长因子-β(TGF-β)和白细胞介素-17(IL-17)水平。结果与T0相比,IFN-γ仅在T2时升高(P<0.01),而IL-2从T1持续升高至T4,TNF-α持续升高至T5。IL-4、IL-6、IL-10为Th2细胞因子,与T0相比,IL-6从T3开始升高,在T5时达到高峰,然后开始下降(均P<0.01);IL-10和IL-4在T5时均显著升高(P<0.01),IL-4在T6时恢复正常,而IL-10在T6时仍升高。与T0相比,IL-17从T1开始升高,T4时达到高峰,IL-17水平在T6时仍未恢复到正常水平。TGF-β水平从T1开始下降,T2达到最低值,然后开始升高,但在T5和T6时仍低于T0。结论手术破坏了机体的免疫平衡,导致Th1/Th2细胞向Th2细胞偏移,Th17/Treg细胞向Treg细胞偏移。

Recently, heat treatment between 250 °C and 500 °C has been attempted to improve quality factor (Q) of superconducting radio-frequency cavities at FNAL and KEK. Experiments of such medium temperature (mid-T) bake with furnaces have also been carried out at IHEP. Firstly, over ten 1.3 GHz 1-cell cavities were treated with different temperatures at a small furnace, which all demonstrated improvement of Q and anti-Q-slope phenomenon. The average quality factor has reached 3.6×1010 when the gradient is 16 MV/m，while the highest Q is 4.9×1010@16MV/m;the maximum gradients of these 1-cell cavities are between 25.1 and 36.9 MV/m. Then, the recipe of mid-T furnace bake at 300 °C for 3 hours has been applied to six 1.3 GHz 9-cell cavities at a new big furnace, which have all shown higher Q and anti-Q-slope at medium field (16~24 MV/m). The average quality factor has reached 3.8×1010 when the gradient is 16 MV/m. The maximum gradients of the 9-cell cavities are between 22.7 and 26.5 MV/m. © 2020, CC0.

板材在生产、运输或使用过程中易产生缺陷,影响板材的使用并造成安全隐患。采用传感器阵列成像技术能够直观、清晰地显示出缺陷的相关信息。SH0模态在铝板中传播时无频散现象,波速恒定,在对信号进行处理时,不需要考虑频散特性带来的影响,有利于缺陷定位和成像。基于磁致伸缩换能机理,研制出一种能在板中激励接收SH波最低阶模态即SH0模态的磁致伸缩贴片型传感器,并测试其全向性。以工程中应用广泛的铝板作为研究对象,运用研制的全向性SH0模态磁致伸缩贴片型传感器布置成分布式传感器阵列。利用椭圆成像算法,实现了铝板中不同直径的模拟缺陷成像检测,探究了全向性SH0模态磁致伸缩贴片型传感器阵列的检测能力,并基于ROC曲线设定成像通用阈值,提高了缺陷成像质量。
