1Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices.Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng 2016Light(Science & Applications)2016,5,1:36
2Magnetic resonance diffusion tensor imaging following major ozonated autohemotherapy for treatment of acute cerebral infarction显示文摘Major ozonated autohemotherapy has been shown to promote recovery of upper limb motor function in patients with acute cerebral infarction,but whether major ozonated autohemotherapy affects remote injury remains poorly understood.Here,we assumed that major ozonated autohemotherapy contributes to recovery of clinical function,possibly by reducing remote injury after acute cerebral infarction.Sixty acute cerebral infarction patients aged 30–80 years were equally and randomly allocated to ozone treatment and control groups.Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy(47 mg/L,100 m L ozone) for 10 ± 2 days.Patients in the control group received medical treatment only.National Institutes of Health Stroke Scale score,modified Rankin scale score,and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased,brain function improved,clinical efficiency significantly increased,and no obvious adverse reactions detected in the ozone treatment group compared with the control group.These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury,and additionally,exhibits high safety.Xiao-na Wu Tao Zhang Jun Wang Xiao-yan Liu Zhen-sheng Li Wei Xiang Wei-qing Du Hong-jun Yang Tie-gen Xiong Wen-ting Deng Kai-run Peng Su-yue Pan 2016Neural Regeneration Research2016,11,7:32
3Crosstalk between tumor cells and microenvironment via Wnt pathway in colorectal cancer dissemination显示文摘Invasion and metastasis are the deadly face of malignant tumors. Considering the high rate of incidence and mortality of colorectal cancer, it is critical to determine the mechanisms of its dissemination. In the parallel investigation of the invasive front and tumor center area of colorectal cancer (CRC), observation of heterogeneous β-catenin distribution and epithelial-mesenchymal transition (EMT) at the invasive front suggested that there might be a crosstalk between tumor cells and the tumor microenvironment. Wnt signaling pathway is also involved in the cancer progression due to its key role in CRC tumorigenesis. Moreover, in recent years, there is increasing evidence that the regulators of microenvironment, including extracellular matrix, growth factors and inflammatory factors, are associated with the activation of Wnt pathway and the mobility of tumor cells. In this review, we will try to explain how these molecules trigger metastasis via the Wnt pathway.Dan Huang, Xiang Du, Department of Pathology, Cancer Hospital of Fudan University Department of Oncology, Shanghai Medical College, Fudan University, Shanghai 200032, China 2008World Journal of Gastroenterology2008,14,12:22

5Noncoding RNAs in gastric cancer: Research progress and prospects显示文摘Noncoding RNAs(nc RNAs) have attracted much attention in cancer research field. They are involved in cellular development, proliferation, differentiation and apoptosis. The dysregulation of nc RNAs has been reported in tumor initiation, progression, invasion and metastasis in various cancers, including gastric cancer(GC). In the past few years, an accumulating body of evidence has deepened our understanding of nc RNAs, and several emerging nc RNAs have been identified, such as PIWI-interacting RNAs(pi RNAs) and circular RNAs(circ RNAs). The competing endogenous RNA(ce RNA) networks include m RNAs, micro RNAs, long nc RNAs(lnc RNAs) and circ RNAs, which play critical roles in the tumorigenesis of GC. This review summarizes the recent hotspots of nc RNAs involved in GC pathobiology and their potential applications in GC. Finally, we briefly discuss the advances in the ce RNA network in GC.Meng Zhang Xiang Du 2016World Journal of Gastroenterology2016,22,29:20

7CD133:A cancer stem cells marker, is used in colorectal cancers显示文摘Colorectal cancer is one of the most common malignant tumors worldwide. A model of cancer development involving cancer stem cells has been put forward because it provides a possible explanation of tumor hierarchy. Cancer stem cells are characterized by their proliferation, tumorigenesis, differentiation, and selfrenewal capacities, and chemoradiotherapy resistance. Due to the role of cancer stem cells in tumor initiation and treatment failure, studies of cancer stem cell markers, such as CD133, have been of great interest. CD133, a five-transmembrane glycoprotein, is widely used as a marker to identify and isolate colorectal cancer stem cells. This marker has been investigated to better understand the characteristics and functions of cancer stem cells. Moreover, it can also be used to predict tumor progression, patient survival, chemoradiotherapy resistance and other clinical parameters. In this review, we discuss the use of CD133 in the identification of colorectal cancer stem cell, which is currently controversial. Although the function of CD133 is as yet unclear, we have discussed several possible functions and associated mechanisms that may partially explain the role of CD133 in colorectal cancers. In addition, we focus on the prognostic value of CD133 in colorectal cancers. Finally, we predict that CD133 may be used as a possible target for colorectal cancer treatment.Fei Ren Wei-Qi Sheng Xiang Du 2013World Journal of Gastroenterology2013,19,17:19
8KRAS mutation testing in metastatic colorectal cancer显示文摘The KRAS oncogene is mutated in approximately 35%-45% of colorectal cancers, and KRAS mutational status testing has been highlighted in recent years. The most frequent mutations in this gene, point substitutions in codons 12 and 13, were validated as negative predictors of response to anti-epidermal growth factor receptor antibodies. Therefore, determining the KRAS mutational status of tumor samples has become an essential tool for managing patients with colorectal cancers. Currently, a variety of detection methods have been established to analyze the mutation status in the key regions of the KRAS gene; however, several challenges remain related to standardized and uniform testing, including the selection of tumor samples, tumor sample processing and optimal testing methods. Moreover, new testing strategies, in combination with the mutation analysis of BRAF , PIK3CA and loss of PTEN proposed by many researchers and pathologists, should be promoted. In addition, we recommend that microsatellite instability, a prognostic factor, be added to the abovementioned concomitant analysis. This review provides an overview of KRAS biology and the recent advances in KRAS mutation testing. This review also addresses other aspects of status testing for determining the appropriate treatment and offers insight into the potential drawbacks of mutational testing.Cong Tan Xiang Du 2012World Journal of Gastroenterology2012,18,37:17
9Vascularity of hepatic VX2 tumors of rabbits: Assessment with conventional power Doppler US and contrast enhanced harmonic power Doppler US显示文摘AIM: To investigate the characteristics of the vascularity ofhepatic metastasis.METHODS: Six New Zealand rabbits, weighing averagely2.7±0.4 kg, were selected and operated to establish hepaticVX2 tumor carrier model. Hepatic VX2 tumors were thenimaged with conventional B mode US, second harmonicimaging (SHI), color Doppler flow imaging (CDFI), powerDoppler imaging (PDI) and harmonic PDI by a transducerS8 connected to HP-5 500 ultrasound system. A kind of selfmade echo contrast agent was intravenously injected at adose of 0.01 mL/kg through ear vein, and then the venouspassage was cleaned with sterilized saline.RESULTS: Totally, 6 hypoechoic lesions and 3 hyperechoiclesions were found in the six carrier rabbits with a mean sizeabout 2.1±0.4 cm under conventional B mode ultrasound, theywere oval or round in shape with a dear outline or a hypoechoichalo at the margin of the lesions. Contrast agent could notchange the echogenicity of the lesions under conventional Bmode and SHI, however, it could greatly increase the flowsensitivity of the lesions under PDI and harmonic PDI. Nutrientartery of these metastatic lesions might also be well depictedunder contrast enhanced PDI and harmonic PDI.CONCLUSION: Our result suggested that contrast enhancedPDI, especially harmonic PDI, was a promised method inthe detection of vascularity of hepatic tumor nodules.Wen-Hua Du Wei-Xiao Yang Xiang Wang Xiu-Qin Xiong Yi Zhou Tao Li Department of US, Daping Hospital & Research Institute of Surgery, the Third Military Medical University, Chongqing 400042, China 2003World Journal of Gastroenterology2003,9,2:17

11Vision,application scenarios,and key technology trends for 6G mobile communications显示文摘With the global commercialization of the fifth-generation(5G)network,many countries,including China,USA,European countries,Japan,and Korea,have started exploring 6G mobile communication network,following the tradition of“planning the next while commercializing one generation”.Currently,studies on 6G networks are at the infancy stage.Research on the vision and requirements for 6G is still ongoing,and the industry is yet to clarify the key enabling technologies for 6G.However,6G will certainly build on the success of 5G.Therefore,developing high-quality 5G networks and seamlessly integrating 5G with verticals are the priorities before 2030,when 6G is projected to be commercialized.Also,global 5G standards will keep evolving to better support vertical applications.As a milestone,the Third-Generation Partnership Project(3GPP)published Release 16 in July 2020,which continuously enhanced the capabilities of mobile broadband service based on Release 15 and realized the support for low-delay and high-reliability applications,such as Internet of Vehicles and industrial Internet.Currently,3GPP is working on Releases 17 and 18,focusing on meeting the demands of medium-and high-data-rate machine communication with low-cost and high-precision positioning,which will be published in June 2022.Thus,6G networks will further expand the application fields and scope of the Internet of Things to accommodate those services and applications that are beyond the capabilities of 5G networks.Herein,we present our vision,application scenarios,and key technological trends for 6G networks.Furthermore,we propose several future research opportunities in 6G networks with regard to industrialization and standardization.Zhiqin WANG Ying DU Kejun WEI Kaifeng HAN Xiaoyan XU Guiming WEI Wen TONG Peiying ZHU Jianglei MA Jun WANG Guangjian WANG Xueqiang YAN Jiying XIANG He HUANG Ruyue LI Xinhui WANG Yingmin WANG Shaohui SUN Shiqiang SUO Qiubin GAO Xin SU 2022Science China(Information Sciences)2022,65,5:17
12Resistance to apoptosis should not be taken as a hallmark of cancer显示文摘In the research community, resistance to apoptosis is often considered a hallmark of cancer. However, pathologists who diagnose cancer via microscope often see the opposite. Indeed, increased apoptosis and mitosis are usually observed simultaneously in cancerous lesions. Studies have shown that increased apoptosis is associated with cancer aggressiveness and poor clinical outcome. Furthermore, overexpression of Bcl-2, an antiapoptotic protein, is linked with better survival of cancer patients. Conversely, Bax, CD95, Caspase-3, and other apoptosis-inducing proteins have been found to promote carcinogenesis. This notion of the role of apoptosis in cancer is not new; cancer cells were found to be short-lived 88 years ago. Given these observations, resistance to apoptosis should not be considered a hallmark of cancer.Rui-An Wang Zeng-Shan Li Qing-Guo Yan Xiu-Wu Bian Yan-Qing Ding Xiang Du Bao-Cun Sun Yun-Tian Sun Xiang-Hong Zhang 2014Chinese Journal of Cancer2014,33,2:15
13Myocardial infarction secondary prevention study (MISPS)显示文摘Background Traditional Chinese medicine (TCM), especially herbal medicine, has been widely used in China and now is also being increasingly used in other countries for the treatment of cardiovascular diseases. Although many studies have demonstrated that certain Chinese herbal products are effective and safe for the treatment of cardiovascular diseases, most of these lack sufficient quality. Therefore, large randomized clinical trials and further scientific research to determine its safety, effectiveness are necessary.QiShen YiQi Dripping Pills (QSYQDP) is a herbal preparation clinically used in the treatment and prevention of coronary artery disease. Preliminary observations have shown its safety and effectiveness. Methods/Design This randomized, controlled trial will recruit 3600 patients with a history of myocardial infarction. Patients will be randomized into two groups by a Centr-Randomized System. One group receives QSYQDP, the other group receive aspirin. This trial protocol will describe eligibility criteria, detailed information on the treatment definition, blinding, endpoints, statistical methods, sample size determination, data management, legal aspects, and the current status of the trial. Discussion This trial is one of the first randomized, controlled clinical trial to evaluate the efficacy and safety of traditional Chinese herbal medicine in the treatment and secondary prevention of coronary artery disease. The results of this study should help to define the role of TCM in modern medical care, as well as to provide the management strategy for CAD patients in China and other countries.Hongcai SHANG Guohua DAI Junhua HANG Yaozu XIANG Yang WANG Junping ZHANG Wuxun DU Jingyuan MAO Chen YAO Weiliang WENG Tiancai WEN Boli ZHANG 2006Journal of Geriatric Cardiology2006,3,2:14
14Variations of Laohugou Glacier No.12 in the western Qilian Mountains, China, from 1957 to 2015显示文摘Glaciers were solid reservoirs and important water resources in western China,but they were retreating significantly in context of global warming.Laohugou Glacier No.12 was the largest valley glacier in Qilian Mountains.In this study,realtime kinematic(RTK)data,topographic map and World View-2 satellite imagery were used to measure changes in terminus,extent and volume of Laohugou Glacier No.12.Results showed that Laohugou Glacier No.12 was shrinking significantly since 1957.From1960 to 2015,the terminus reduction of Laohugou Glacier No.12 was 402.96 m(3.99%)in total,and glacier length decreased to 9.7 km from 10.1 km.Reduction of glacier area and volume were the most obvious.From 1957 to 2015,glacier area and volume decreased by 1.54 km^2(7.03%)and 0.1816 km^3,respectively.Reduction trend of terminus and area was slowing in 1950-1980s,even stable for a period in the mid-1980s,and then accelerated.Ice core analysis result and nearly meteorological station data shown an increasing trend of temperature in 1957-2015,it was a main reason of continuous retreating of Laohugou Glacier No.12.LIU Yu-shuo QIN Xiang CHEN Ji-zu LI Zhen-lin WANG Jing DU Wen-tao GUO Wan-qin 2018Journal of Mountain Science2018,15,1:14

16A Prospective Randomized Multicenter Controlled Trial on Salvianolate for Treatment of Unstable Angina Pectoris in A Chinese Elderly Population显示文摘Objective: To evaluate the efficacy and safety of salvianolate in elderly patients with unstable angina pectoris(UAP). Methods: A prospective double-blind randomized placebo-controlled multicenter trial in elderly patients with UAP from 13 third-grade class-A hospitals in China was performed. A total of 318 patients were randomly allocated in a 1:1 ratio to an experimental group(160 patients) and a control group(158 patients). The experimental group was treated with salvianolate for 14 days on the basis of conventional medicine, and the control group was given a placebo for 14 days with the same criteria. Follow-up was lasted 28 days in both groups. The primary endpoint was biweekly frequency of angina pectoris attacks. The secondary endpoints included biweekly dosage of nitroglycerin, the Seattle Angina Questionnaire, angina pectoris severity and duration, myocardial injury markers, high-sensitivity C-reactive protein(hs-CRP) and N-terminal pro-B-type natriuretic peptide(NT-proBNP), as well as major adverse cardiovascular events(MACEs). Safety was assessed according to adverse events and serious adverse events. Results: Baseline characteristics were similar between treatment groups. Compared with those in the control group, the frequency of biweekly angi na attacks(2.92 vs. 4.08, P =0.025), th e biweekly dosage of nitroglycerin, as well as the severity and duration of angina attacks(P <0.01) were reduced by salvianolate. The Seattle Angina Questionnaire score was also significantly improved in the experimental group than in the control group(P <0.05). No significant differences were observed between the two groups with respect to the incidence of MACEs. Salvianolate was well tolerated. Conclusions: Salvianolate appear to have efficacy and well tolerated for elderly patients with UAP.CUI Hua LI Xiao-ying GAO Xue-wen LU Xiang WU Xiu-ping WANG Xiao-fei ZHENG Xiang-qing HUANG Kui LIU Feng LUO Zhi YUAN Hui-shu SUN Gang KONG Jian DU Xiao-hong ZHENG Jin LIU Hong-ying ZHANG Wen-ju 2019Chinese Journal of Integrative Medicine2019,25,10:13
17Cropland redistribution to marginal lands undermines environmental sustainability显示文摘Cropland redistribution to marginal land has been reported worldwide;however,the resulting impacts on environmental sustainability have not been investigated sufficiently.Here we investigated the environmental impacts of cropland redistribution in China.As a result of urbanization-induced loss of high-quality croplands in south China(~8.5 t ha^(-1)),croplands expanded to marginal lands in northeast(~4.5 t ha^(-1)) and northwest China(~2.9 t ha^(-1)) during 1990-2015 to pursue food security.However,the reclamation in these low-yield and ecologically vulnerable zones considerably undermined local environmental sustainability,for example increasing wind erosion(+3.47%),irrigation water consumption(+34.42%),fertilizer use(+20.02%) and decreasing natural habitats(-3.11%).Forecasts show that further reclamation in marginal lands per current policies would exacerbate environmental costs by 2050.The future cropland security risk will be remarkably intensified because of the conflict between food production and environmental sustainability.Our research suggests that globally emerging reclamation of marginal lands should be restricted and crop yield boost should be encouraged for both food security and environmental benefits.Wenhui Kuang Jiyuan Liu Hanqin Tian Hao Shi Jinwei Dong Changqing Song Xiaoyong Li Guoming Du Yali Hou Dengsheng Lu Wenfeng Chi Tao Pan Shuwen Zhang Rafiq Hamdi Zherui Yin Huimin Yan Changzhen Yan Shixin Wu Rendong Li Jiuchun Yang Yinyin Dou Wenbin Wu Liqiao Liang Bao Xiang Shiqi Yang 2022National Science Review2022,9,1:13
18Long Distance Transmission of SARS-CoV-2 from Contaminated Cold Chain Products to Humans——Qingdao City,Shandong Province,China,September 2020显示文摘Summary What is already known about this topic?Though coronavirus disease 2019(COVID-19)has largely been controlled in China,several outbreaks of COVID-19 have occurred from importation of cases or of suspected virus-contaminated products.Though several outbreaks have been traced to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)isolated on the outer packaging of cold chain products,live virus has not been obtained.Huilai Ma Zhaoguo Wang Xiang Zhao Jun Han Yong Zhang Hong Wang Cao Chen Ji Wang Fachun Jiang Jie Lei Jingdong Song Shaofeng Jiang Shuangli Zhu Huihui Liu Dongyan Wang Yao Meng Naiying Mao Yanhai Wang Zhen Zhu Zhixiao Chen Bingling Wang Qinqin Song Haijun Du Qun Yuan Dong Xia Zhiqiang Xia Peipei Liu Yuchao Wu Zijian Feng Ruqin Gao George F.Gao Wenbo Xu 2021China CDC weekly2021,3,30:13
19Effects of gas supersaturation on lethality and avoidance responses in juvenile rock carp(Procypris rabaudi Tchang)显示文摘Laboratory experiments were conducted to determine the effects of total dissolved gas(TDG) supersaturation on acute lethality and avoidance responses in juvenile rock carp(Procypris rabaudi Tchang).The juvenile rock carp were exposed to water with different levels of supersaturation(105%,115%,120%,125%,130%,135%,140%,and 145%) and depth of 0.20 m at 25 °C for 60 h.Median lethal time(LT50) was used to assess the lethal responses corresponding to different levels of gas supersaturation.The results show that half of the juvenile rock carp died at the 120%,125%,130%,135%,140%,and 145% levels of supersaturation,and the LT50 corresponding to different levels of supersaturation was 18.7,15.4,8.2,6.6,3.5,and 1.7 h.When the level of supersaturated water is below 115%,the mortality is negligible.Avoidance responses were observed 5 min after the fish were put into equilibrated water(99%,0.08 m deep) and water with different supersaturated levels(105%,115%,125%,135%,and 145%,0.08 m deep) at 25 °C.The fish exhibited strong avoidance responses in supersaturated water when the gas supersaturation was above 135%.However,they exhibited an obvious preference to supersaturated water when the gas supersaturation was below 115%.Thus,the juvenile rock carp can likely survive in water with a supersaturated level of 115%.Xiang HUANG Ke-feng LI Jun DU Ran LI 2010Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010,11,10:13
