＜正＞In the present work, we will report a novel, efficient and regioselective approach for the thiocyanation of aromatic and heteroaromatic compounds using ammonium thiocyanate as a thiocyanation reagent and oxone （2KHSO5·KHSO4·K2SO4） as an oxidant. The studied substrates were indoles, carbazoles, anilines and pyrrole. Using indoles as substrates, the reaction gave unique 3-thiocyano substituted indoles in high yield:

太子参为石竹科多年生草本植物,以根部入药,药用价值高,市场需求大,但其栽培过程中存在严重的连作障碍问题,连作导致产量品质严重下降,病虫害猖獗,探索太子参连作障碍形成的机制及其消减措施意义重大.本研究以广泛栽培的"柘参2号"为试验材料,采用土壤农化分析、高效液相色谱(HPLC)分析、荧光定量PCR(qPCR)等技术对不同连作年限或不同消减措施下太子参根际土壤的主要养分、酚酸含量动态及特异菌群变化进行分析.结果显示:太子参连作导致产量显著下降,与正茬相比产量下降达43.5%,而水旱轮作和微生物菌肥处理可不同程度缓解其障碍效应.太子参连作土壤主要养分(如速效氮、速效磷、速效钾、全钾)未降反升,但导致土壤酸化.HPLC分析表明,太子参连作下或者随生长时期的推进,土壤酚酸类物质并未表现出明显的积累效应,膨大中期和收获期重茬土壤中大部分酚酸含量甚至低于正茬土壤.进一步荧光定量PCR分析发现,太子参连作导致前期分离筛选到的几类病原菌(如尖孢镰刀菌、踝节霉菌、Kosakonia sacchari)的绝对含量显著上升,而水旱轮作和微生物菌肥处理可有效降低3类病原菌的含量,改善微生态结构.综上认为,太子参连作障碍的发生并非由土壤养分匮乏或者酚酸持续积累直接造成,可能主要与连作下土传病原微生物的大量繁殖爆发有关,本研究结果为深入揭示太子参连作障碍的形成机制及消减修复机制提供了理论依据.

Inverted perovskite solar cells （PSCs） have received great attention owing to the high certificated power conversion efficiency（PCE） reaching 26.7%. However, interfacial charge recombination is far superior to perovskite bulk charge recombination due to the use of fullerenes and their derivatives in inverted perovskite solar cells, which induces devastating open circuit voltage（VOC） losses. For this reason the present work attempts to use 4-chloropiperidine hydrochloride for the upper surface modification of perovskite to construct a quasi-two-dimensional （2D） structure with suitable 2D layer widths （n=2, 3 dominant）,which has a smaller electron carrier transport barrier without sacrificing short-circuit current （JSC） in the device. This strategy effectively passivates the interfacial defect states while promoting energy level alignment to achieve carrier dissociation and equilibrium transport at the interface, which in turn resulted in improved fill factor （FF）. In addition, additional energy levels are provided by 2D perovskites to collect hot carriers, resulting in improved device open circuit voltage （VOC）. As a result, the device PCE increases from 22.37%to 24.11%after the 4CPD treatment. In addition, the 4CPD-treated PSCs maintain 90%of the initial PCE after storage in an N2atmosphere at 50°C for 1,080 h, whereas the control devices show a 15%PCE loss under the same aging conditions. This work provides new opportunities to suppress interfacial charge recombination in inverted devices.

目的通过建立急性肺损伤大鼠模型和体外肺泡巨噬细胞培养体系，观察急性肺损伤中，肺泡巨噬细胞在氨溴索干预前后细胞因子表达的情况，探讨氨溴索可能的肺损伤保护机制。方法一、体内实验：大鼠24只，随机分成3组，每组8只：（1）正常对照组；（2）急性肺损伤组：采用腹腔注射酵母悬液方法复制大鼠急性肺损伤模型；（3）氨溴索治疗组：建立Au大鼠模型后用氨溴索干预。观察指标主要有：肺部病理学改变、测量大鼠肺系数、血氧分压，肺泡巨噬细胞TNF-α、IL-10、IL-24mRNA的表达则采用通过逆转录-聚合酶链式反应（RT-PCR）技术检测。二、体外实验：收集肺泡巨噬细胞后分3组：（1）正常对照组：肺泡巨噬细胞中加无菌生理盐水；（2）LPS组：予LPS 10mg／L刺激肺泡巨噬细胞；（3）LPS＋氨溴索组：予LPS 10mg／L和氨溴索180μmol／L刺激肺泡巨噬细胞。分别于刺激前（0h），刺激后（6、12、24h）留取细胞。通过RT-PCR技术检测肺泡巨噬细胞TNF-α、IL-10、IL-24mRNA的表达变化。结果氨溴索治疗组在病理改变，肺系数，动脉血氧分压等各项指标均优于急性肺损伤组，氨溴索干预治疗组，TNF-α、IL-10、IL-24mRNA表达水平均明显下降，与急性肺损伤组比较差异有统计学意义（P〈0．05），但仍高于正常对照组。体外实验也得出了相同的结论。结论氨溴索可抑制急性肺损伤或LPS刺激的肺泡巨噬细胞TNF-α、IL-10、IL-24细胞因子mRNA的表达水平。
