1An overview of the use of plastic-film mulching in China to increase crop yield and water-use efficiency显示文摘Since 1990,crop yields have stagnated in many parts of the world,posing a significant challenge to global food security[1].As such;innovative solutions are needed to increase the resource-use efficiency of cropping systems to produce more grains per unit area.Dongbao Sun Haigang Li Enli Wang Wenqing He Weiping Hao Changrong Yan Yuzhong Li Xurong Mei Yanqing Zhang Zhanxiang Sun Zhikuan Jia Huaiping Zhou Tinglu Fan Xucheng Zhang Qin Liu Fengju Wang Chaochun Zhang Jianbo Shen Qingsuo Wang Fusuo Zhang 2020National Science Review2020,7,10:19
2The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus.Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang 2016Science China(Life Sciences)2016,59,9:5

4PEG-asparaginase in BFM-90 regimen improves outcomes in adults with newly diagnosed lymphoblastic lymphoma显示文摘Objective: Although L-asparaginase(L-ASP) is a standard treatment for lymphoblastic lymphoma(LBL),hypersensitivity reactions by some patients limit its application. Polyethylene glycol-conjugated asparaginase(PEGASP) has a lower immunogenicity and is a standard treatment in all pediatric acute lymphoblastic leukemia(ALL).In this study, we investigated the efficacy and toxicity of PEG-ASP instead of L-ASP as used in the BFM-90regimen(PEG-ASP-BFM-90) for adult LBL.Methods: Between June 2012 and July 2015, we treated 30 adult patients with newly diagnosed LBL, using PEGASP-BFM-90 in a prospective, multicenter and single-arm clinical study at 5 participating institutions in China.Results: All the 30 patients, including 19 males and 11 females with a median age of 30(range: 18–62) years,completed 128 times of the PEG-ASP, with the median of 4(range: 2–6) times. Patients did not receive radiotherapy at this time. The overall response rate was 86.7%(26/30), with 50.0%(15/30) complete response and36.7%(11/30) partial response. The 3-year overall survival was 46.0% [95% confidence interval(95% CI),28.2%–64.8%], and the 3-year progression-free survival was 43.0%(95% CI, 25.7%–62.0%). Major adverse events were myelosuppression, reduced fibrinogen, liver dysfunction and digestive tract toxicities. No allergic reaction and no treatment-related mortality or severe complications were recorded.Conclusions: Our clinical data and observed outcomes indicate that 1 dose of PEG-ASP can replace multiple doses of native L-ASP in BFM-90, with predominantly grade 3–4 neutropenia for adult LBL, and no therapyrelated deaths. The effect is similar to previous reports of PEG-ASP-containing regimens for adult ALL. Major advantages include less serious allergic reactions, 2–3 weeks of action duration, and convenience for patients and physicians.Wen Zheng Hanyun Ren Xiaoyan Ke Mei Xue Yongqing Zhang Yan Xie Ningjing Lin Meifeng Tu Weiping Liu Lingyan Ping Zhitao Ying Chen Zhang Lijuan Deng Xiaopei Wang Yuqin Song Jun Zhu 2017Chinese Journal of Cancer Research2017,29,1:2

8Oxidized phospholipids are ligands for LRP6显示文摘Low-density lipoprotein receptor–related protein 6(LRP6) is a co-receptor for Wnt signaling and can be recruited by multiple growth factors/hormones to their receptors facilitating intracellular signaling activation. The ligands that bind directly to LRP6 have not been identified. Here, we report that bioactive oxidized phospholipids(oxPLs) are native ligands of LRP6, but not the closely related LRP5. oxPLs are products of lipid oxidation involving in pathological conditions such as hyperlipidemia, atherosclerosis, and inflammation. We found that cell surface LRP6 in bone marrow mesenchymal stromal cells(MSCs) decreased rapidly in response to increased oxPLs in marrow microenvironment. LRP6 directly bound and mediated the uptake of oxPLs by MSCs. oxPL-LRP6 binding induced LRP6 endocytosis through a clathrin-mediated pathway, decreasing responses of MSCs to osteogenic factors and diminishing osteoblast differentiation ability. Thus, LRP6 functions as a receptor and molecular target of oxPLs for their adverse effect on MSCs, revealing a potential mechanism underlying atherosclerosis-associated bone loss.Lei Wang Yu Chai Changjun Li Haiyun Liu Weiping Su Xiaonan Liu Bing Yu Weiqi Lei Bin Yu Janet L.Crane Xu Cao Mei Wan 2018Bone Research2018,6,3:1

14Visbreaking of heavy petroleum oil catalyzed by SO_(4)^(2-)/ZrO_(2)solid super-acid doped with Ni^(2+) or Sn^(2+)显示文摘SO_(4)^(2-)/ZrO_(2) solid super-acid catalysts(SZ)doped with Ni^(2+)or Sn^(2+)(Ni^(2+)/SZ,Sn^(2+)/SZ)were prepared for catalytic visbreaking of heavy petroleum oil from Shengli oil field.The visbreaking reactions were carried out at 240uC and 3–4 MPa for 24 h using a heavy petroleum oil to catalyst mass ratio of 100:0.05.The effect of water content on viscosity of heavy petroleum oil was also investigated.Both catalysts can promote thermolysis of heavy petroleum oil and the viscosity was reduced from 0.319 Pa·s to 0.135 Pa?s for Ni^(2+)/SZ and 0.163 Pa·s for(Sn^(2+)/SZ)with visbreaking rates of 57.7% and 48.9%,respectively.After visbreaking,the saturated hydrocarbon content increased while aromatics,resin,asphaltene,sulfur and nitrogen content decreased.The presence of water was disadvantageous to visbreaking of heavy petroleum oil.Ping JING Qingbiao LI Mei HAN Daohua SUN Lishan JIA Weiping FANG 2008Frontiers of Chemical Science and Engineering2008,2,2:0
15Giant Magnetoresistance Effect in Melt Spun CoCu granular Alloys显示文摘granular magnetic Co_(x)Cu_(1-x)(x=0.05-0.5)alloy ribbons were prepared by melt spinning method,and the structural,magnetotransport,magnetic properties and the effects of annealing on these properties were studied by x-ray diffraction,vibrating sample magnetometer,magnetoresistance measurement at room temperature.Giant magnetoresistance was observed over a broad range of Co concentrations with a maximum magnetoresistance(MR)ratio of 7.8%(at x=0.20 and 500℃ annealing)under a magnetic field of 20kOe.The MR ratio increases with the annealing temperature and reaches a maximum at about 500℃ and then drops.The dependence of MR and magnetization on magnetic field for various granule parameters were studied by controlling the nucleation and growth of Co granules.LI Min ZHAO Xuegen ZHAO Tongyun ZHAO Jiangao SHEN Baogen CHAI Weiping GU Yousong MAI Zhenhong MEI Liangmo 1994Chinese Physics Letters1994,11,8:0
16Earthquake-related anomalies recorded by two borehole bulk-strain meters显示文摘This paper gives a report on borehole bulk-strain data recorded at the seismostations of Liuhe and Nantong in Jiangsu Province from January 1, 2003 to December 31, 2008. While the data at Nantong showed much noise possibly due to site instability and no earthquake-related changes, the data at Liuhe showed anomalous changes that began one to several weeks before three earthquakes of magnitude 4.0 to 6.0 at epicentral distances up to 400 km.Zheng Jiangrong Wang Jun Mei Weiping Bao Haiying 2011Geodesy and Geodynamics2011,2,1:0
