The Anjiayingzi gold deposit in Chifeng County, Inner Mongolia is located in the central part of the gold mineralization belt of the northern margin of the North China Craton (NCC), and is adjacent to the Paleozoic Inner Mongolia-Da Hinggan Mountains orogenic belt in the north. The Chifeng-Kaiyuan fault, which separates the NCC from this orogenic belt, is considered to be a regional ore-controlling structure. The Anjiayingzi gold deposit is a mediate-size quartz lode-gold deposit and is hosted by the Anjiayingzi quartz monzonite that was emplaced into the basement composed of early Precambrian gneisses. Rhyolitic and porphyritic dikes are generally associated with the gold mineralization. Zircon U-Pb analyses suggest that the Anjia- yingzi granite was emplaced from 132 Ma to 138 Ma, while the rhyolitic dikes that occupy the same fracture system as the gold-bearing quartz veins and locally crosscut the gold lodes crystallized from 125 Ma to 127 Ma. These results constrain the mineralization age between 126 Ma and 132 Ma, early Cretaceous time for the Anjiayingzi gold deposit. This mineralization age is consistent with that of the gold deposits in other major gold-bearing areas of the NCC, such as the Jiaodong Peninsula and the Xiaoqinling Mountain, and specially is roughly coeval with the geodynamic reversion of the NCC in Mesozoic. This coincidence probably indicates that the gold deposits in the NCC, including the Anjiayingzi deposit, formed in a similar geodynamic setting characterized by large-scale thinning of the lithosphere underlying the NCC.

子宫发育异常,即先天性子宫畸形(CUA),是女性生殖系统在胚胎6~20周双侧副中肾管发育、融合和/或吸收异常所导致的先天性子宫形态和功能异常,大多数患者的症状是不孕、反复流产、早产或胎位异常等。子宫内膜异位性疾病(ED)包括子宫内膜异位症(EMT)和子宫腺肌病(AM),常合并存在。当子宫内膜腺体和间质出现在子宫体以外的部位时,称为EMT。当子宫内膜腺体和间质侵入肌层时,称为AM。双子宫合并ED临床不多见,可出现月经异常、痛经、不孕等,本文回顾分析1例先天性双子宫畸形合并ED,并查阅相关文献进行分析总结,探讨双子宫畸形及ED常见的相关临床问题。

带隙可调的钙钛矿材料在室内光伏(IPVs)领域具有广阔的应用前景.然而,与室内光相匹配的宽带隙钙钛矿通常导电性较差,缺陷密度较高,往往不利于电荷提取和传输,限制了其光伏特性.在这里,我们通过调节Br/I比,探究了不同带隙三阳离子钙钛矿的IPVs特性.研究表明,宽带隙钙钛矿能充分利用室内光,在低照度下能获得较高的开路电压,但高Br/I比的钙钛矿具有较高的缺陷密度,不利于获得高短路电流密度和填充因子.通过进一步研究不同带隙钙钛矿的结晶动力学、缺陷密度和电荷传输特性,我们发现主流观念中高效IPVs着重考虑室内光伏材料的带隙是不全面的,我们证明了通过适当降低宽带隙晶体中的Br含量可以获得室内光伏特性更优异的器件.也就是说,室内光伏晶体材料的制备需要兼顾带隙和电荷传输特性.在此工作中,平衡带隙和电荷传输的器件(Br 0.23,1.62 eV)在1035 lux的LED灯照射下取得了40.71%的最佳效率.我们的研究为高效室内光伏的设计提供了新思路.

Circular dichroism（CD） is usually used to study supramolecular chirality. With the development of CD methods, diffuse transmission CD（DTCD） and diffuse reflectance CD（DRCD） have been developed. However, the relationship among CD, DTCD and DRCD has not been well-studied. A chiral low molecular weight gelator was synthesized, which can result in a transparent physical gel in deionized water. The field-emission electron microscopy images show that the gel is able to self-assemble into left-handed helical fibers. The CD and DTCD spectra are al- most identical, but they partially differ from the DRCD spectrum. Based on the TD-DFT calculated CD spectrum, the DRCD spectrum is shown to be more accurate.

Single-handed helical and C-shaped 3-aminophenol-formaldehyde resin nanotubes were prepared via a supramolecular templating approach. The chiral templates and 3-aminophenol were initially organized into helical nanoribbons, followed by the adsorption of formaldehyde onto the surfaces of the helical nanoribbons. Subsequent to polymerization and further thermosetting of the resin oligomers, 3-aminophenol-formaldehyde resin nanotubes were obtained after removing the templates. When low amounts of 3-aminophenol were added, straight C-shaped 3-aminophenol-formaldehyde resin nanotubes were obtained. Increasing the amount of added 3-aminophenol led to the formation of single-handed helical nanotubes instead. When the single-handed helical resin nanotubes were car- bonized at 900 ~C under Ar, single-handed helical carbonaceous nanotubes were obtained. Raman spectrum indicates that this carbon is predominantly amorphous. Circular dichroism spectra illustrate that both the helical resin nanotubes and the carbonaceous nanotubes exhibit optical activity. This work indicates that the added amount and the edge-adsorption mode of the precursors on the templates determine the final morphology and chirality of the products.

目的观察低浓度含Mn^(2+)化合物和自噬抑制药物氯喹长时间共同作用对神经细胞株PC12细胞的毒性作用及机制。方法取对数生长期PC12细胞,分别给予0(对照)、5、10、25、50、100、200μM氯化锰,5、10、25、50、100μM氯喹;染毒24 h。采用噻唑蓝(MTT)法检测氯化锰和氯喹对细胞存活率的影响。并联合给药,观察两种化合物共同作用24、48、72 h对细胞存活率的影响。进一步检测线粒体呼吸功能,探讨氯化锰和氯喹可能的毒性作用机理。结果与空白对照组比较,氯化锰和氯喹单独给药均对细胞增殖活力具有抑制作用,其效应表现为给药剂量不断增加,而细胞存活率逐渐降低。实验选取对细胞增殖活力无显著影响的氯化锰和氯喹浓度分别为40μM和2.5μM;在此浓度下,与空白对照组相比,氯喹单独给药24、48和72 h,其细胞存活率和线粒体呼吸功能没有明显改变;氯化锰单独给药作用72 h,其线粒体呼吸功能未受影响;但氯化锰和氯喹联合给药共同作用72 h后,细胞的存活率和线粒体呼吸功能均显著降低(P<0.05)。结论低浓度的氯化锰和氯喹长时间共同作用对PC12细胞具有明显毒性,其毒性机制可能与其对线粒体功能损伤有关。
