1儿童NTRK重排间叶源性肿瘤临床病理学观察显示文摘目的:探讨儿童NTRK重排间叶源性肿瘤临床和病理学特征,以提高对该类疾病的认识。方法:收集上海交通大学医学院附属上海儿童医学中心及新加坡KK Women′s and Children′s Hospital从2017年1月至2019年9月5例手术切除标本,采用EnVision法检测免疫组织化学表型,荧光原位杂交(FISH)检测相关基因并对NTRK基因重排进行克隆性分析。结果:该组5例患儿,3例男性,2例女性。年龄从3个月到13岁,部位包括软组织(膝、胸腔、腹壁)和肾,肿瘤大小为4.5~12.5 cm。组织学检查主要呈梭形细胞肿瘤,浸润性生长,可伴有炎性细胞。免疫表型上,肿瘤细胞阳性表达Pan-TRK,分子检测均存在NTRK基因重排,包括DCTN1-NTRK1的发现。除2例目前接受靶向药物治疗,其余均为无疾病进展病例,随访时间9~29个月。结论:NTRK重排间叶源性肿瘤,其肿瘤发生部位广泛,组织学图像多变。免疫组织化学Pan-TRK可以帮助诊断,NTRK基因检测确认其存在重排是诊断的金标准,对不能完整切除或有复发、转移病例建议靶向药物治疗。殷敏智 马靖 何巧 沈萍 陈洁枫 金晓婷 张忠德 Chik Hong Kuick Chen Huiyi Eileen Hui Qi Ng Sze Jet Aw Kenneth Tou En Chang 2020中华病理学杂志2020,49,7:6

3A Novel Dimer──Heteropolytungstate with a Vanadium Atom as the Centre ──Synthesis and Structural Characterization of (H_3O)_4[VW_(12)O_(40)Na(H_2O)_4]_2显示文摘A novel dimer tungstovanadate, (H 3O) 4[VW 12 O 40 Na(H 2O) 4] 2, was hydrothermally synthesized and structurally characterized by single crystal X ray diffraction, IR spectra, TGA DSC thermal analysis and polarograpy. The yellowish crystal crystallized in the triclinic system, space group P1, a =1 464 5(3) nm, b =1 468 6(3) nm, c =1 411 1(3) nm, α=111 82(2)°, β=93 17(3)°, γ=117 47(3)°, V =2 210 6(8) nm 3, Z=1, D c=4 552 g·cm -3 , λ (Mo Kα )=0 071 073 nm, μ =31 402 mm -1 , F(000)=2 648, R =0 078 0. The title compound consists of two Keggin structure units linked together with two hydrated sodium cations to form a dimer with a porous structure with the pore dimension of 0 766 nm×0 778 5 nm.

4Significant loss of soil inorganic carbon at the continental scale显示文摘Widespread soil acidification due to atmospheric acid deposition and agricultural fertilization may greatly accelerate soil carbonate dissolution and CO_(2) release.However,to date,few studies have addressed these processes.Here,we use meta-analysis and nationwide-survey datasets to investigate changes in soil inorganic carbon(SIC)stocks in China.We observe an overall decrease in SIC stocks in topsoil(0-30 cm)(11.33 g C m^(-2)yr^(-1))from the 1980s to the 2010s.Total SIC stocks have decreased by∼8.99±2.24%(1.37±0.37 Pg C).The average SIC losses across China(0.046 Pg C yr^(-1))and in cropland(0.016 Pg C yr^(-1))account for∼17.6%-24.0%of the terrestrial C sink and 57.1%of the soil organic carbon sink in cropland,respectively.Nitrogen deposition and climate change have profound influences on SIC cycling.We estimate that∼19.12%-19.47%of SIC stocks will be further lost by 2100.The consumption of SIC may offset a large portion of global efforts aimed at ecosystem carbon sequestration,which emphasizes the importance of achieving a better understanding of the indirect coupling mechanisms of nitrogen and carbon cycling and of effective countermeasures to minimize SIC loss.Xiao-Dong Song Fei Yang Hua-Yong Wu Jing Zhang De-Cheng Li Feng Liu Yu-Guo Zhao Jin-Ling Yang Bing Ju Chong-Fa Cai Biao Huang Huai-Yu Long Ying Lu Yue-Yu Sui Qiu-Bing Wang Ke-Ning Wu Feng-Rong Zhang Ming-Kui Zhang Zhou Shi Wan-Zhu Ma Gang Xin Zhi-Ping Qi Qing-Rui Chang En Ci Da-Gang Yuan Yang-Zhu Zhang Jun-Ping Bai Jia-Ying Chen Jie Chen Yin-Jun Chen Yun-Zhong Dong Chun-Lan Han Ling Li Li-Ming Liu Jian-Jun Pan Fu-Peng Song Fu-Jun Sun Deng-Feng Wang Tian-Wei Wang Xiang-Hua Wei Hong-Qi Wu Xia Zhao Qing Zhou Gan-Lin Zhang 2022National Science Review2022,9,2:2
