1Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears.Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG 2021Science China(Information Sciences)2021,64,1:122

4Effects of Subsoiling on Soil Moisture Under No-Tillage for Two Years显示文摘In order to improve the water use efficiency under conservation tillage,the effects of subsoiling on soil moisture under no-tillage were studied. An experiment of 40 cm subsoiling in a field kept under no-tillage for 2 years was operated from 2005 to 2006. Based on the data of the soil moisture and crop yield,the physical basis of subsoiling for water conservation and yield increase was analyzed. The results showed that the soil water storage under subsoiling,from the soil surface to a depth of 100 cm was more than that under no-tillage for the growth season. In the 0-100 cm soil depth,the soil moisture in 50-100 cm depth under subsoiling was more compared with no-tillage,which increased when it's drought and decreased when it's rainy with the increase in soil depth. Compared with no-tillage,subsoiling could reduce the water consumption of oats in the 0-50 cm depth and increase the water consumption in the 50-100 cm depth. Also,subsoiling increased the yield by 18.29% and the water use efficiency by 16.8% in a two-year average. The effects of subsoiling on water conservation and yield increase were affected by precipitation,and a well-proportioned rainfall was better to increase yield and water use efficiency. Meanwhile,subsoiling decreased bulk density,which increased with the available precipitation. Subsoiling under no-tillage is the effective rotation tillage to contain more soil moisture and improve water use efficiency in ecotone of North China.QIN Hong-ling GAO Wang-sheng MA Yue-cun MA Li YIN Chun-mei CHEN Zhe CHEN Chun-lan 2008Agricultural Sciences in China2008,7,1:32
5Effects of probiotics on nonalcoholic fatty liver disease:A meta-analysis显示文摘AIM:To investigate the relationship between the gutliver axis and nonalcoholic fatty liver disease(NAFLD),we performed a meta-analysis to evaluate the effects of probiotic therapy in NAFLD.METHODS:We searched PubMed,Medline,Embase,Web of Science,the Cochrane Library and Chinese Biomedicine Database for all relevant randomized controlled trials on probiotics in patients with NAFLD/nonalcoholic steatohepatitis(NASH).A statistical analysis was performed using RevMan 5.0 software.RESULTS:Four randomized trials involving 134 NAFLD/NASH patients were included.The results showed that probiotic therapy signifcantly decreased alanine aminotransferase(ALT),aspartate transaminase(AST),total-cholesterol(T-chol),high density lipoprotein(HDL),tumor necrosis factor(TNF)-αand homeostasis model assessment of insulin resistance(HOMAIR)[ALT:weighted mean difference(WMD)-23.71,95%CI:-33.46--13.95,P<0.00001;AST:WMD-19.77,95%CI:-32.55--7.00,P=0.002;T-chol:WMD-0.28,95%CI:-0.55--0.01,P=0.04;HDL:WMD-0.09,95%CI:-0.16-0.01,P=0.03;TNF-α:WMD-0.32,95%CI:-0.48--0.17,P<0.0001;HOMA-IR:WMD-0.46,95%CI:-0.73--0.19,P=0.0008].However,the use of probiotics was not associated with changes in body mass index(BMI),glucose(GLU)and low density lipoprotein(LDL)(BMI:WMD 0.05,95%CI:-0.18-0.29,P=0.64;GLU:WMD 0.05,95%CI:-0.25-0.35,P=0.76;LDL:WMD-0.38,95%CI:-0.78-0.02,P=0.06).CONCLUSION:Probiotic therapies can reduce liver aminotransferases,total-cholesterol,TNF-αand improve insulin resistance in NAFLD patients.Modulation of the gut microbiota represents a new treatment for NAFLD.Yan-Yan Ma Lin Li Chao-Hui Yu Zhe Shen Li-Hua Chen You-Ming Li 2013World Journal of Gastroenterology2013,19,40:28
6Astragaloside Ⅳ inhibits pathological functions of gastric cancer-associated fibroblasts显示文摘AIM To investigate the inhibitory effect of astragaloside IV on the pathological functions of cancer-associated fibroblasts,and to explore the underlying mechanism.METHODS Paired gastric normal fibroblast(GNF) and gastric cancer-associated fibroblast(GCAF) cultures were established from resected tissues. GCAFs were treated with vehicle control or different concentrations of astragaloside Ⅳ. Conditioned media were prepared from GNFs,GCAFs,control-treated GCAFs,and astragaloside Ⅳ-treated GCAFs,and used to culture BGC-823 human gastric cancer cells. Proliferation,migration and invasion capacities of BGC-823 cells were determined by MTT,wound healing,and Transwell invasion assays,respectively. The action mechanism of astragaloside Ⅳ was investigated by detecting the expression of micro RNAs and the expression and secretion of the oncogenic factor,macrophage colonystimulating factor(M-CSF),and the tumor suppressive factor,tissue inhibitor of metalloproteinase 2(TIMP2),in different groups of GCAFs. The expression of the oncogenic pluripotency factors SOX2 and NANOG in BGC-823 cells cultured with different conditioned media was also examined.RESULTS GCAFs displayed higher capacities to induce BGC-823 cell proliferation,migration,and invasion than GNFs(P < 0.01). Astragaloside Ⅳ treatment strongly inhibited the proliferation-,migration-and invasion-promoting capacities of GCAFs(P < 0.05 for 10 μmol/L,P < 0.01 for 20 μmol/L and 40 μmol/L). Compared with GNFs,GCAFs expressed a lower level of micro RNA-214(P < 0.01) and a higher level of micro RNA-301 a(P < 0.01). Astragaloside Ⅳ treatment significantly upregulated micro RNA-214 expression(P < 0.01) and down-regulated micro RNA-301 a expression(P < 0.01) in GCAFs. Reestablishing the micro RNA expression balance subsequently suppressed M-CSF production(P < 0.01) and secretion(P < 0.05),and elevated TIMP2 production(P < 0.01) and secretion(P < 0.05). Consequently,the ability of GCAFs to increase SOX2 and NANOG expression in BGC-823 cells was abolished by astragaloside Ⅳ.CONCLUSION Astragaloside Ⅳ can inhibit the pathological functions of GCAFs by correcting their dysregulation of micro RNA expression,and it is promisingly a potent therapeutic agent regulating tumor microenvironment.Zhen-Fei Wang Da-Guang Ma Zhe Zhu Yong-Ping Mu Yong-Yan Yang Li Feng Hao Yang Jun-Qing Liang Yong-Yan Liu Li Liu Hai-Wen Lu 2017World Journal of Gastroenterology2017,23,48:15
7CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric carcinoma显示文摘AIM To investigate the role of CXC chemokine receptor(CXCR)-7 and CXCL12 in lymph node and liver metastasis of gastric carcinoma.METHODS In 160 cases of gastric cancer, the expression of CXCR7 and CXCL12 in tumor and matched tumoradjacent non-cancer tissues, in the lymph nodes around the stomach and in the liver was detected using immunohistochemistry to analyze the relationship between CXCR7/CXCL12 expression and clinicopathological features and to determine whether CXCR7 and CXCL12 constitute a biological axis to promote lymph node and liver metastasis of gastric cancer. Furthermore, the CXCR7 gene was silenced and overexpressed in human gastric cancer SGC-7901 cells, and cell proliferation, migration and invasiveness were measured by the MTT, wound healing and Transwell assays, respectively. RESULTS CXCR7 expression was up-regulated in gastric cancer tissues(P = 0.011). CXCR7/CXCL12 expression was significantly related to poor tumor differentiation, high tumor stage and lymph node(r = 0.338, P = 0.000) and liver metastasis(r = 0.629, P = 0.000). The expression of CXCL12 in lymph node and liver metastasis was higher than that in primary gastric cancer tissues(χ2 = 6.669, P = 0.010; χ2 = 25379, P = 0.000), and the expression of CXCL12 in lymph node and liver metastasis of gastric cancer was consistent with the positive expression of CXCR7 in primary gastric cancer(r = 0.338, P = 0.000; r = 0.629, P = 0.000). Overexpression of the CXCR7 gene promoted cell proliferation, migration and invasion. Silencing of the CXCR7 gene suppressed SGC-7901 cell proliferation, migration and invasion. Human gastric cancer cell lines expressed CXCR7 and showed vigorous proliferation and migratory responses to CXCL12.CONCLUSION The CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric cancer. CXCR7 is considered a potential therapeutic target for the treatment of gastric cancer.Qi Xin Na Zhang Hai-Bo Yu Qin Zhang Yan-Fen Cui Chuan-Shan Zhang Zhe Ma Yan Yang Wei Liu 2017World Journal of Gastroenterology2017,23,17:14

9Carcinogenic potential of duodenal reflux juice from patients with long-standing postgastrectomy显示文摘AIM To determine, whether study on thecarcinogenic potential of reflux juice frompatients with remote gastrectomy could clarifythe inherent relationship between duodenalreflux and gastric stump cancer.METHODS A total of 37 reflux juice samples(13 Billroth T, 24 Billroth Ⅱ ) were employed inthe present study. A two- stage transformationassay using BALB/c 3T3 cells was carried out totest the initiating or promoting activity of thesesamples.RESULTS Two of 18 (11.1%) reflux samplesexerted initiating activities, whereas 9/19(47.4%) samples enhanced the MNNG-initiafingcell transformation, suggesting the duodenalreflux juice might more frequently possess thetumor-promoter activity (P = 0. 029). In addition,there was no difference in initiating activities ofthe samples irrespective of surgical procedures(P=0.488), while Billroth Ⅱ samples exhibitedstronger tumor-promoter activity than Billroth Ⅰsamples (P = 0.027). Furthermore, the promoteractivities were well correlated with thehistological changes of the stomas (rs = 0.625,P = 0.004), but neither their cytotoxicities norinitiating activities had this correlation( Probabilities were 0.523 and 0.085,respectively).CONCLUSION The duodenal reflux juice frompatients with remote postgastrectomy did havecarcinogenic potential, and suggested thattumor-promoting activity should principallyaccount for the high incidence of gastric cancerin gastrectomy patients. In contrast, it isdifficult to explain the high stump-cancerincidence with the 'N-nitroso compounds'theory-a popular theory for the intact stomachcarcinogenesis, and it seemed to be justified tofocus chemoprevention of this cancer on thetumor-promoting potential of reflux juice.Zhe Fu Ma~1 Zhong Yu Wang~1 Jun Ran Zhang~2 Peng Gong~1 Hai Long Chen~1 ~1Departrnent of General Surgery,First Hospital,Dalian Medical University,Dalian 116011,China ~2Department of Radiation Oncology,Massachusetts General Hospital and Harvard Medical School,Charlestown,MA 02129,USADr.Zhe Fu Ma graduated from Shanxi Medical College in 1993,nowPh.D.,M.D.in Department of Surgery,Dalian Medical University,majoring gastroenteric cancer,having 4 papers published.Correspondence to:Dr.Zhe Fu Ma.Department of General Surgery,First Hospital,Dalian Medical University,Dalian 116011,China Tel.0086-411-4720334 2001World Journal of Gastroenterology2001,7,3:9
10Study of HIV-1 Drug Resistance in Patients Receiving Free Antiretroviral Therapy in China显示文摘To investigate the prevalence of drug-resistance mutations,resistance to antiretroviral drugs,and the subsequent virological response to therapy in treatment-naive and antiretroviral-treated patients infected with HIV/AIDS in Henan,China,a total of 431 plasma samples were collected in Queshan county between 2003 and 2004,from patients undergoing the antiretroviral regimen Zidovudine + Didanosine + Nevirapine(Azt+Ddi+Nvp).Personal information was collected by face to face interview.Viral load and genotypic drug resistance were tested.Drug resistance mutation data were obtained by analyzing patient-derived sequences through the HIVdb Program(http://gffzz38c50ed9119344cfhfc00wkxfb5cu6uff.ffgz.tsg.suse.edu.cn).Overall,38.5% of treatment-naive patients had undetectable plasma viral load(VL),the rate significantly increased to 61.9% in 0 to 6 months treatment patients(mean 3 months)(P<0.005)but again significantly decrease to 38.6% in 6 to 12 months treatment patients(mean 9 months)(P<0.001)and 40.0% in patients receiving more than 12 months treatment(mean 16 months)(P<0.005).The prevalence of drug resistance in patients who had a detectable VL and available sequences were 7.0%,48.6%,70.8%,72.3% in treatment-na?ve,0 to 6 months treatment,6 to 12 months treatment,and treatment for greater than 12 months patients,respectively.No mutation associated with resistance to Protease inhibitor(PI)was detected in this study.Nucleoside RT inhibitor(NRTI)mutations always emerged after non-nucleoside RT inhibitor(NNRTI)mutations,and were only found in patients treated for more than 6 months,with a frequency less than 5%,with the exception of mutation T215Y(12.8%,6/47)which occurred in patients treated for more than 12 months.NNRTI mutations emerged quickly after therapy begun,and increased significantly in patients treated for more than 6 months(P<0.005),and the most frequent mutations were K103N,V106A,Y181C,G190A.There had been optimal viral suppression in patients undergoing treatment for less than 6 months in Queshan,Henan.The drug resistance strains were highly prevalent in antiretroviral-treated patients,and increased with the continuation of therapy,with many patients encountering virological failure after 6 months therapy.Xin-ping LIP Hui XING Zhe WANG Xue-feng SI Lian-en WANG Hua CHENG Wei-guo CUI Shu-lin JIANG Ling-jie LIAO Hai-wei ZHOU Jiang-hong HUANG Hong PENG Peng-fei MA Yi-ming SHAO 2007中国病毒学2007,22,3:9
11Transcriptional landscape of rice roots at the single-cell resolution显示文摘There are two main types of root systems in flowering plants,namely taproot systems of dicots and fibrous root systems found in monocots.Despite this fundamental split,our current knowledge of cellular and molecular mechanism driving root development is mainly based on studies of the dicot model Arabidopsis.However,the world major crops are monocots and little is known about the transcriptional programs underlying cell-type specification in this clade.Here,we report the transcriptomes of more than 20000 single cells derived from root tips of two agronomically important rice cultivars.Using combined computational and experimental analyses we were able to robustly identify most of the major cell types and define novel cell-type-specific marker genes for both cultivars.Importantly,we found divergent cell types associated with specific regulatory programs,including phytohormone biosynthesis,signaling,and response,which were well conserved between the two rice cultivars.In addition,we detected substantial differences between the cell-type transcript profiles of Arabidopsis and rice.These species-specific features emphasize the importance of analyzing tissues across diverse model species,including rice.Taken together,our study provides insight into the transcriptomic landscape of major cell types of rice root tip at single-cell resolution and opens new avenues to study cell-type specification,function,and evolution in plants.Qing Liu Zhe Liang Dan Feng Sanjie Jiang Yifan Wang Zhuoying Du Ruoxi Li Guihua Hu Pingxian Zhang Yanfei Ma Jan ULohmann Xiaofeng Gu 2021Molecular Plant2021,14,3:9
12Hard X-ray Imager (HXI) onboard the ASO-S mission显示文摘Hard X-ray Imager(HXI)is one of the three scientific instruments onboard the Advanced Spacebased Solar Observatory(ASO-S)mission,which is proposed for the 25th solar maximum by the Chinese solar community.HXI is designed to investigate the non-thermal high-energy electrons accelerated in solar flares by providing images of solar flaring regions in the energy range from 30 keV to 200 keV.The imaging principle of HXI is based on spatially modulated Fourier synthesis and utilizes about 91 sets of bi-grid sub-collimators and corresponding LaBr3 detectors to obtain Fourier components with a spatial resolution of about 3 arcsec and a time resolution better than 0.5 s.An engineering prototype has been developed and tested to verify the feasibility of design.In this paper,we present background,instrument design and the development and test status of the prototype.Zhe Zhang Deng-Yi Chen Jian Wu Jin Chang Yi-Ming Hu Yang Su Yan Zhang Jian-Ping Wang Yao-Ming Liang Tao Ma Jian-Hua Guo Ming-Sheng Cai Yong-Qiang Zhang Yong-Yi Huang Xiao-Yan Peng Zong-Bin Tang Xuan Zhao Hong-He Zhou Lian-Guo Wang Jing-Xing Song Miao Ma Guang-Zhou Xu Jian-Feng Yang Di Lu Ying-Hong He Jin-You Tao Xiao-Long Ma Bao-Gang Lv Yan-Ping Bai Cai-Xia Cao Yu Huang Wei-Qun Gan 2019Research in Astronomy and Astrophysics2019,19,11:9
13Analysis and Design of Four-Plate Capacitive Wireless Power Transfer System for Undersea Applications显示文摘This paper presents a four-plate undersea capacitive wireless power transfer(CPT)system for underwater applications such as autonomous underwater vehicles(AUVs).Generally,a CPT system transfers the power based on electric fields.The complex resonant compensation networks are used to make the CPT system work in the resonant condition.The resonant voltage is always very high.It will be a big challenge to the human safety.In this paper,a virtual electrons periodic reciprocating flow theory is proposed for the CPT system.In one switching cycle,the electrons firstly flow in the forward direction through the forward path and then flow in the inverse direction through the inverse path.The CPT system has been deeply studied with the vacuum dielectric or the air dielectric.However,for the CPT system,there are few papers to show the underwater application.In this paper,an undersea four-plate CPT system is designed and studied in the underwater condition.The two coupling capacitors and other elements of the CPT system could build a closed-loop path.A small value inductor is adapted as a resonant compensation network for the four-plate CPT system.The DC voltage is inverted to the AC voltage in the primary side with the single-phase full-bridge inverter.The resonant voltage is rectified to the DC voltage in the secondary side with the single-phase full-bridge diode rectifier.A 100 W power level CPT system is constructed to verify the theory analysis and the calculation.The theory analysis is verified by the simulated and experimental results.The stable output voltage and load power are achieved in this paper.Lei Yang Yuanqi Zhang Xiaojie Li Jiale Jian Zhe Wang Jingjing Huang Li Ma Xiangqian Tong 2021CES Transactions on Electrical Machines and Systems2021,5,3:9
14Two-Dimensional Tellurium:Progress,Challenges,and Prospects显示文摘Since the successful fabrication of two-dimensional(2D)tellurium(Te)in 2017,its fascinating properties including a thickness dependence bandgap,environmental stability,piezoelectric effect,high carrier mobility,and photoresponse among others show great potential for various applications.These include photodetectors,field-effect transistors,piezoelectric devices,modulators,and energy harvesting devices.However,as a new member of the 2D material family,much less known is about 2D Te compared to other 2D materials.Motivated by this lack of knowledge,we review the recent progress of research into 2D Te nanoflakes.Firstly,we introduce the background and motivation of this review.Then,the crystal structures and synthesis methods are presented,followed by an introduction to their physical properties and applications.Finally,the challenges and further development directions are summarized.We believe that milestone investigations of 2D Te nanoflakes will emerge soon,which will bring about great industrial revelations in 2D materials-based nanodevice commercialization.Zhe Shi Rui Cao Karim Khan Ayesha Khan Tareen Xiaosong Liu Weiyuan Liang Ye Zhang Chunyang Ma Zhinan Guo Xiaoling Luo Han Zhang 2020Nano-Micro Letters2020,12,8:8
15Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species.Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li 2021Molecular Plant2021,14,6:8
16A novel nomogram individually predicting disease-specific survival after D2 gastrectomy for advanced gastric cancer显示文摘Background:Few studies have shown nomograms that may predict disease-specific survival(DSS)probability after curative D2 gastrectomy for advanced gastric cancer(AGC),particularly among Chinese patients.This study sought to develop an elaborative nomogram that predicts long-term DSS for AGC in Chinese patients.Methods:A retrospective study was conducted on 6753 AGC patients undergoing D2 gastrectomy between January 1,2000 and December 31,2012 from three large medical hospitals in China.We assigned patients from Sun Yat-sen University Cancer Center to the training set,and patients from the First Affiliated Hospital of China Medical University and Tianjin Medical University Cancer Hospital to two separate external validation sets.A multivariate survival analysis was performed using Cox proportional hazards regression model in a training set,and a nomogram was constructed.Harrell’s C-index was used to evaluate discrimination and calibration plots were used to validate similarities between survival probabilities predicted by the nomogram model and actual survival rates in two validation sets.Results:The multivariate Cox regression model identified age,tumor size,location,Lauren classification,lymphatic/venous invasion,depth of invasion,and metastatic lymph node ratio as covariates associated with survival.In the training set,the nomogram exhibited superior discrimination power compared with the 8th American Joint Com-mittee on Cancer TNM classification(Harrell’s C-index,0.82 vs.0.74;P<0.001).In two validation sets,the nomogram’s discrimination power was also excellent relative to TNM classification(C-index,0.83 vs.0.75 and 0.81 vs.0.74,respec-tively;P<0.001 for both).After calibration,the nomogram produced survival predictions that corresponded closely with actual survival rate.Conclusions:The established nomogram was able to predict 3-,5-,and 10-year DSS probabilities for AGC patients.Validation revealed that this nomogram exhibited excellent discrimination and calibration capacity,suggesting its clinical utility.Wei Wang Zhe Sun Jing-Yu Deng Xiao-Long Qi Xing-Yu Feng Cheng Fang Xing-Hua Ma Zhen-Ning Wang Han Liang Hui-Mian Xu Zhi-Wei Zhou 2018Cancer Communications2018,38,1:8
17Outcomes of Adults with Acute Lymphoblastic Leukemia After Autologous Hematopoietic Stem Cell Transplantation and the Significance of Pretransplantation Minimal Residual Disease: Analysis from a Single Center of China显示文摘Zhe Ding Ming-Zhe Han Shu-Lian Chen Qiao-Ling Ma Jia-Lin Wei Ai-Ming Pang Xiao-Yu Zhang Chen Liang Jian-Feng Yao Yi-Geng Cao Si-Zhou Feng Er-Lie Jiang 2015Chinese Medical Journal2015,,15:7
18Advances in crop phenotyping and multi-environment trials显示文摘Efficient evaluation of crop phenotypes is a prerequisite for breeding, cultivar adoption, genomics and phenomics study. Plant genotyping is developing rapidly through the use of high-throughput sequencing techniques,while plant phenotyping has lagged far behind and it has become the rate-limiting factor in genetics, large-scale breeding and development of new cultivars. In this paper,we consider crop phenotyping technology under three categories. The first is high-throughput phenotyping techniques in controlled environments such as greenhouses or specifically designed platforms. The second is a phenotypic strengthening test in semi-controlled environments, especially for traits that are difficult to be tested in multi-environment trials(MET), such as lodging, drought and disease resistance. The third is MET in uncontrolled environments, in which crop plants are managed according to farmer's cultural practices.

19Genomic insights into the fast growth of paulownias and the formation of Paulownia witches' broom显示文摘Paulownias are among the fastest growing trees in the world,but they often suffer tremendous loss of wood production due to infection by Paulownia witches'broom(PaWB)phytoplasmas.In this study,we have sequenced and assembled a high-quality nuclear genome of Paulownia fortunei,a commonly cultivated paulownia species.The assembled genome of P.fortunei is 511.6 Mb in size,with 93.2%of its sequences anchored to 20 pseudo-chromosomes,and it contains 31985 protein-coding genes.Phylogenomic analyses show that the family Paulowniaceae is sister to a clade composed of Phrymaceae and Orobanchaceae.Higher photosynthetic efficiency is achieved by integrating C3 photosynthesis and the crassulacean acid metabolism pathway,which may contribute to the extremely fast growth habit of paulownia trees.Comparative transcriptome analyses reveal modules related to cambial growth and development,photosynthesis,and defense responses.Additional genome sequencing of PaWB phytoplasma,combined with functional analyses,indicates that the effector PaWB-SAP54 interacts directly with Paulownia PfSPLa,which in turn causes the degradation of PfSPLa by the ubiquitin-mediated pathway and leads to the formation of witches'broom.Taken together,these results provide significant insights into the biology of paulownias and the regulatory mechanism for the formation of PaWB.Yabing Cao Guiling Sun Xiaoqiao Zhai Pingluo Xu Liming Ma Minjie Deng Zhenli Zhao Haibo Yang Yanpeng Dong Zhonghai Shang Yujie Lv Lijun Yan Haifang Liu Xibing Cao Bingbing Li Zhe Wang Xiaogai Zhao Haiyan Yu Fan Wang Wen Ma Jinling Huang Guoqiang Fan 2021Molecular Plant2021,14,10:7
20Predictive factors associated with gefitinib response in patients with advanced non-small-cell lung cancer(NSCLC)显示文摘Purpose: A number of different clinical characteristics have been reported to singly correlate with therapeutic activity of epidermal growth factor receptor(EGFR) tyrosine kinase inhibitors(TKIs) in advanced non-small-cell lung cancer(NSCLC). This study aimed to identify predictive factors associated with prognostic benefits of gefitinib.Patients and methods: EGFR gene typing in 33 advanced NSCLC patients received gefitinib(250 mg/day) were analyzed with mutant-enriched PCR assay. Gefitinib response was evaluated with potential predictive factors retrospectively.Results: The overall objective response rate(ORR) and median progression-free survival(PFS) in the 33 patients treated by gefitinib were 45.5% and 3.0(2.0-4.0) months. The ORR and median PFS in EGFR gene mutation patients were significantly higher/longer than those in EGFR gene wild-type patients(P<0.01). Similarly, the ORR and median PFS in non-smoker patients were significantly higher/longer than those in smoker patients(P<0.05, P<0.01, respectively). However, no difference for ORR and median PFS occurred between male and female patients. Logistic multivariate analysis showed that only EGFR mutated gene was significantly associated with the ORR(P<0.01). Both EGFR mutated gene and non-smoker were the major factors that contributed to PFS(P<0.05). Conclusions: EGFR mutated gene and non-smoker status are potential predictors for gefitinib response in NSCLC patients.Lian Chen Rui Chen Zhe Zhu Yichen Zhang Zhengwei Wen Yun Li Xiaoming Li Yuwen Luo Liyu Ma Shuguang Lin Xin Chen 2014Chinese Journal of Cancer Research2014,26,4:7
