3Changes in China’s lakes: climate and human impacts显示文摘Lakes have played a critical role in providing water and ecosystem services for people and other organisms in China for millennia.However,accelerating climate change and economic boom have resulted in unprecedented changes in these valuable lakes.Using Landsat images covering the entity of the country,we explored the changes in China’s lakes and the associated driving forces over the last 30 years(i.e.mid-1980 s to 2015).We discovered that China’s lakes have changed with divergent regional trends:in the sparsely populated Tibetan Plateau,lakes are abundant and the lake area has increased dramatically from 38596 to46831 km^2(i.e.increased by 8235 km^2,or 21.3%),whereas,in the densely populated northern and eastern regions,lakes are relatively scarce and the lake area has decreased from 36659 to 33657 km^2(i.e.decreased by 3002 km^2,or 8.2%).In particular,severe lake decreases occurred in the Mongolia-Xinjiang Plateau and the Eastern Plain(-2151 km^2).Statistical analyses indicated that climate was the most important factor controlling lake changes in the Tibetan Plateau,the Yun-Gui Plateau and the Northeast Plain.However,the strength of climatic control on lake changes was low in the Eastern Plain and the Mongolia-Xinjiang Plateau,where human activities,e.g.impoldering,irrigation and mining,have caused serious impacts on lakes.Further lake changes will exacerbate regional imbalances between lake resources and population distribution,and thus may increase the risk of water-resource crises in China.Shengli Tao Jingyun Fang Suhui Ma Qiong Cai Xinyu Xiong Di Tian Xia Zhao Leqi Fang Heng Zhang Jiangling Zhu Shuqing Zhao 2020National Science Review2020,7,1:14
4Correlation between adult pyrethroid resistance and knockdown resistance(kdr)mutations in Aedes albopictus(Diptera:Culicidae)field populations in China显示文摘Background:Arboviral disease transmitted by Aedes albopictus such as dengue fever is an important threat to human health.Pyrethroid resistance raises a great challenge for mosquito control.A systematic assessment of Ae.albopictus resistance status in China is urgently needed,and the study of correlation between pyrethroid resistance and knockdown resistance(kdr)mutations would provide information to guide the control of the Ae.albopictus vector.Methods:Five field populations of Ae.albopictus were collected from Jinan(JN),Hangzhou(HZ),Baoshan(BS),Yangpu(YP)and Haikou(HK),China in 2017.Insecticide-impregnated papers were prepared with four pyrethroid chemicals,deltamethrin,permethrin,beta-cypermethrin and lambda-cyhalothrin.The susceptibility of Ae.albopictus to pyrethroids was tested by the WHO tube assay.Kdr mutations were identified by PCR and sequencing.Moreover,the correlation analysis between kdr alleles and pyrethroid resistance was performed.Results:All five populations of Ae.albopictus showed resistance to four pyrethroid insecticides.One kdr mutant allele at codon 1532 and three at 1534 were detected with frequency of 5.33%(I1532T),44.20%(F1534S),1.83%(F1534 L)and 0.87%(F1534C),respectively.Both 1532 and 1534 mutation mosquitoes were found in the BS and YP populations.Allele I1532T was negatively correlated with deltamethrin resistance phenotype(OR<1),while F1534S mutation was positively correlated with deltamethrin and permethrin resistance(OR>1).Conclusions:The five field populations of Ae.albopictus adults were all resistant to deltamethrin,permethrin,betacypermethrin and lambda-cyhalothrin.Mutant F1534S was clearly associated with pyrethroid resistance phenotype in Ae.albopictus and this could be developed as a molecular marker to monitor the pyrethroid resistance problem in China.Jing-Peng Gao Han-Ming Chen Hua Shi Heng Peng Ya-Jun Ma 2018Infectious Diseases of Poverty2018,7,1:11

7MicroTom Metabolic Network: Rewiring Tomato Metabolic Regulatory Network throughout the Growth Cycle显示文摘Tomato(Solanum lycopersicum)is a major horticultural crop worldwide and has emerged as a preeminent model for metabolic research.Although many research efforts have focused on the analysis of metabolite differences between varieties and species,the dynamics of metabolic changes during the tomato growth cycle and the regulatory networks that underlie these changes are poorly understood.In this study,we integrated high-resolution spatio-temporal metabolome and transcriptome data to systematically explore the metabolic landscape across 20 major tomato tissues and growth stages.In the resulting MicroTom Metabolic Network,the 540 detected metabolites and their co-expressed genes could be divided into 10 distinct clusters based on their biological functions.Using this dataset,we constructed a global map of the major metabolic changes that occur throughout the tomato growth cycle and dissected the underlying regulatory network.In addition to verifying previously well-established regulatory networks for important metabolites,we identified novel transcription factors that regulate the biosynthesis of important secondary metabolites such as steroidal glycoalkaloids and flavonoids.Our findings provide insights into spatiotemporal changes in tomato metabolism and generate a valuable resource for the study of metabolic regulatory processes in model plants.Yan Li Yang Chen Lu Zhou Shengjie You Heng Deng Ya Chen Saleh Alseekh Yong Yuan Rao Fu Zixin Zhang Dan Su Alisdair R.Fernie Mondher Bouzayen Tao Ma Mingchun Liu Yang Zhang 2020Molecular Plant2020,13,8:10
8Tribological evaluation of surface modified H13 tool steel in warm forming of Ti–6Al–4V titanium alloy sheet显示文摘The H13 hot-working tool steel is widely used as die material in the warm forming of Ti–6Al–4V titanium alloy sheet. However, under the heating condition, severe friction and lubricating conditions between the H13 tools and Ti–6Al–4V titanium alloy sheet would cause difficulty in guaranteeing forming quality. Surface modification may be used to control the level of friction force, reduce the friction wear and extend the service life of dies. In this paper, four surface modification methods(chromium plating, TiAlN coating, surface polishing and nitriding treatment)were applied to the H13 surfaces. Taking the coefficient of friction(CoF) and the wear degree as evaluation indicators, the high-temperature tribological behavior of the surface modified H13 steel was experimentally investigated under different tribological conditions. The results of this study indicate that the tribological properties of the TiAlN coating under dry friction condition are better than the others for a wide range of temperature(from room temperature to 500 C), while there is little difference of tribological properties between different surface modifications under graphite lubricated condition, and the variation law of CoF with temperature under graphite lubricated is opposite to that under the dry friction.Wang Dan Li Heng Yang He Ma Jun Li Guangjun 2014Chinese Journal of Aeronautics2014,27,4:9

10Self-supported high-entropy alloy electrocatalyst for highly efficient H_(2) evolution in acid condition显示文摘Developing non-precious catalysts as Pt substitutes for electrochemical hydrogen evolution reaction(HER)with superior stability in acidic electrolyte is of critical importance for large-scale,low-cost hydrogen production from water.Herein,we report a CoCrFeNiAl high-entropy alloy(HEA)electrocatalyst with self-supported structure synthesized by mechanical alloying and spark plasma sintering(SPS)consolidation.The HEA after HF treatment and in situ electrochemical activation for 4000 cycles of cyclic voltammetry(HF-HEAa2)presents favourable activity with overpotential of 73 mV to reach a current density of 10 mA cm^(2) and a Tafel slope of 39.7 mV dec1.The alloy effect of Al/Cr with Co/Fe/Ni at atomic level,high-temperature crystallization,as well as consolidation by SPS endow CoCrFeNiAl HEA with high stability in 0.5 M H2SO4 solution.The superior performance of HF-HEAa2 is related with the presence of metal hydroxides/oxides groups on HEA.Peiyan Ma Mingming Zhao Long Zhang Heng Wang Junfeng Gu Yuchen Sun Wei Ji Zhengyi Fu 2020Journal of Materiomics2020,6,4:8

12Identification and characterization of rice blast resistance gene Pid4 by a combination of transcriptomic profiling and genome analysis显示文摘Map-based cloning of plant disease resistance (R) genes is time-consuming. Here, we reported the isolation of blast R gene Pid4 using comparative transcriptomic profiling and genome-wide sequence analysis. Pid4 encodes a coiled-coil nucleotide-binding site leucine-rich repeat(CC-NBS-LRR) protein and is constitutively expressed at diverse developmental stages in the rice variety Digu. The Pid4 protein is localized in both the nucleus and cytoplasm. Introduction of Pid4 into susceptible rice cultivars confers race-specific resistance to leaf and neck blast. Amino acid sequence comparison and blast resistance spectrum tests showed that Pid4 is a novel R gene, different from the previously reported R genes located in the same gene cluster. A Pid4 Indel marker was developed to facilitate the identification of Pid4 in different rice varieties. We demonstrated that a plant R gene can be quickly isolated using transcriptomic profiling coupled with genome-wide sequence analysis.Zhixiong Chen Wen Zhao Xiaobo Zhu Chengdong Zou Junjie Yin Mawsheng Chern Xiaogang Zhou Heng Ying Xin Jiang Yongzhen Li Haicheng Liao Mengping Cheng Weitao Li Min He Jing Wang Jichun Wang Bingtian Ma Jirui Wang Shigui Li Lihuang Zhu Xuewei Chen 2018Journal of Genetics and Genomics2018,45,12:7
13Chemokines and their receptors play important roles in the development of hepatocellular carcinoma显示文摘The chemokine system consists of four different subclasses with over 50 chemokines and 19 receptors. Their functions in the immune system have been well elucidated and research during the last decades unveils their new roles in hepatocellular carcinoma(HCC). The chemokines and their receptors in the microenvironment influence the development of HCCby several aspects including:inflammation,effects on immune cells,angiogenesis,and direct effects on HCC cells. Regarding these aspects,pre-clinical research by targeting the chemokine system has yielded promising data,and these findings bring us new clues in the chemokine-based therapies for HCC.Chun-Min Liang Long Chen Heng Hu Hui-Ying Ma Ling-Ling Gao Jie Qin Cui-Ping Zhong 2015World Journal of Hepatology2015,7,10:7
14An INS/GNSS integrated navigation in GNSS denied environment using recurrent neural network显示文摘In view of the failure of GNSS signals,this paper proposes an INS/GNSS integrated navigation method based on the recurrent neural network(RNN).This proposed method utilizes the calculation principle of INS and the memory function of the RNN to estimate the errors of the INS,thereby obtaining a continuous,reliable and high-precision navigation solution.The performance of the proposed method is firstly demonstrated using an INS/GNSS simulation environment.Subsequently,an experimental test on boat is also conducted to validate the performance of the method.The results show a promising application prospect for RNN in the field of positioning for INS/GNSS integrated navigation in the absence of GNSS signal,as it outperforms extreme learning machine(ELM)and EKF by approximately 30%and 60%,respectively.Hai-fa Dai Hong-wei Bian Rong-ying Wang Heng Ma 2020Defence Technology(防务技术)2020,16,2:7

16IGHG1 promotes motility likely through epithelial-mesenchymal transition in ovarian cancer显示文摘Objective: Ovarian cancer(OC) is one of the leading causes of death for female cancer patients. COC166-9 is an OC-specific monoclonal antibody and we have identified immunoglobulin γ-1 heavy chain constant region(IGHG1) as its antigen. We explore the function of IGHG1 in proliferation, apoptosis and motility of OC cells further in this research.Methods: IGHG1 expression in OC specimens was detected through immunohistochemistry. Real-time quantitative polymerase chain reaction(RT-q PCR) or western blotting assay was used to test IGHG1 expression in OC cells. Viability of OC cells was tested by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay. Flow cytometry or western blotting assay was used to detect cell cycle and apoptosis. Cellular motility was analyzed by using transwell assay and the markers of epithelial-mesenchymal transition(EMT) were tested through immunoblots.Results: Although it exerts negligible effect on the viability and apoptosis of OC cells, IGHG1 could promote migration and invasion of malignant cells in vitro. Mechanistically, IGHG1 increases the expression of N-cadherin and Vimentin while decreases E-cadherin expression. Additionally, IGHG1 expression in OC specimens is higher relative to the paired normal counterparts. Further analysis demonstrates that the increased IGHG1 expression correlates positively with the lymph node metastasis of OC.Conclusions: IGHG1 promotes the motility of OC cells likely through executing the EMT program. Increased IGHG1 expression in OC specimens is associated with the lymph node metastasis.Jingfeng Qian Fangxing Ji Xue Ye Hongyan Cheng Ruiqiong Ma Xiaohong Chang Chengchao Shou Heng Cui 2018Chinese Journal of Cancer Research2018,30,2:6
17伤害是可以预测和预防的吗?(英文)显示文摘目的伤害是一个重要的公共卫生问题,无论在发达或是发展中国家,伤害是引起死亡及病残的重要原因,尤其是对儿童和青少年,伤害是引起死亡及病残的主要原因。2005年,全球大约有540万人死于伤害,其中的90%发生在中等及欠发达国家。据联合国估计伤害引起的死亡数在2015年将上升到600万人,在2030年将上升至700万。预计在2020年伤害将从现在的死亡原因的第9位上升至第6位。伤害是可以预测和预防的。在人们的观念中,伤害的发生往往是不可预知。因此伤害通常被称作‘意外伤害’。事实并非如此,根据哈登方阵无论在伤害发生前,发生时或是发生后均可通过个体,工具和环境来预防或是降低伤害。和所有的疾病一样伤害也是通过个体,病原(能量)及环境的相互作用发生的。伤害流行病学在伤害的分布及危险因素判断上有着非常重要的意义。伤害监测系统的建立是伤害预防的关键部分。伤害的预防要求多部门的合作。伤害的预防别于其它疾病的预防,除了卫生部门外它还需要其它部门的参与,如工程,公安,交通和法律部门等。朱善宽 MA Xiao-guang Kenneth Heng 2007中华急诊医学杂志2007,16,10:6
18Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2.HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou 2019Science China(Physics,Mechanics & Astronomy)2019,62,3:6
19Pathological changes in the lungs and lymphatic organs of 12 COVID-19 autopsy cases显示文摘Systematic autopsy and comprehensive pathological analyses of COVID-19 decedents should provide insights into the disease characteristics and facilitate the development of novel therapeutics.In this study,we report the autopsy findings from the lungs and lymphatic organs of 12 COVID-19 decedents—findings that evaluated histopathological changes;immune cell signature and inflammatory factor expression in the lungs,spleen and lymph nodes.Here we show that the major pulmonary alterations included diffuse alveolar damage,interstitial fibrosis and exudative inflammation featured with extensive serous and fibrin exudates,macrophage infiltration and abundant production of inflammatory factors(IL-6,IP-10,TNFo?and IL-I f).The spleen and hilar lymph nodes contained lesions with tissue structure disruption and immune cell dysregulation,including lymphopenia and macrophage accumulation.These findings provide pathological evidence that links injuries of the lungs and lymphatic organs with the fatal systematic respiratory and immune malfunction in critically ill COVID-19 patients.Qian Liu Yu Shi Jun Cai Yaqi Duan Rongshuai Wang Hongyan Zhang Qiurong Ruan Jiansha Li Lei Zhao Yifang Ping Rong Chen Liang Ren Xiaochun Fei Heng Zhang Rui Tang Xi Wang Tao Luo Xindong Liu Xuequan Huang Zhenhua Liu Qilin Ao Yong Ren Jing Xiong Zhicheng He Haibo Wu Wenjuan Fu Pengnan Zhao Xinwei Chen Guoqiang Qu Yunyun Wang Xi Wang Jia Liu Dongfang Xiang Sanpeng Xu Xiaowei Zhou Qingrui Li Jinghong Ma Heng Li Jie Zhang Sizhe Huang Xiaohong Yao Yiwu Zhou Chaofu Wang Dingyu Zhang Guoping Wang Liang Liu Xiu-Wu Bian 2020National Science Review2020,7,12:6
