| 8 | Anisotropic 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 | 2016 | Light(Science & Applications)2016，5，1： | 36 |

| 10 | Preliminary results pertaining to coseismic displacement and preseismic strain accumulation of the Lushan M_S7.0 earthquake,as reflected by GPS surveying显示文摘This paper presents the coseismic displacement and preseismic deformation fields of the Lushan MS7.0 earthquake that occurred on April 20,2013.The results are based on GPS observations along the Longmenshan fault and within its vicinity.The coseismic displacement and preseismic GPS results indicate that in the strain release of this earthquake,the thrust rupture is dominant and the laevorotation movement is secondary.Furthermore,we infer that any possible the rupture does not reach the earth’s surface,and the seismogenic fault is most likely one fault to the east of the Guanxian-Anxian fault.Some detailed results are obtainable.(1)The southern segment of the Longmenshan fault is locked preceding the Lushan earthquake.After the Wenchuan earthquake,the strain accumulation rate in the southeast direction accelerates in the epicenter of the Lushan earthquake,and the angle between the principal compressional strain and the seismogenic fault indicates that a sinistral deformation background in the direction of the seismogenic fault precedes the Lushan earthquake.Therefore,it is evident that the Wenchuan MS8.0 earthquake accelerated the pregnancy of the Lushan earthquake.(2)The coseismic displacements reflected by GPS data are mainly located in a region that is 230 km(NW direction)×100 km(SW direction),and coseismic displacements larger than 10 mm lie predominantly in a100-km region(NW direction).(3)On a large scale,the coseismic displacement shows thrust characteristics,but the associated values are remarkably small in the near field(within 70 km)of the earthquake fault.Meanwhile,the thrust movement in this70-km region does not correspond with the attenuation characteristics of the strain release,indicating that the rupture of this earthquake does not reach the earth’s surface.(4)The laevorotation movements are remarkable in the 50-km region,which is located in the hanging wall that is close to the earthquake fault,and the corresponding values in this case correlate with the attenuation characteristics of the strain release. | WU YanQiang JIANG ZaiSen WANG Min CHE Shi LIAO Hua LI Qiang LI Peng YANG YongLin XIANG HePing SHAO ZhiGang WANG WuXing WEI WenXin LIU XiaoXia | 2013 | Chinese Science Bulletin2013，58，28： | 33 |
| 11 | Electro-acupuncture regulates the cholinergic anti-inflammatory pathway in a rat model of chronic obstructive pulmonary disease显示文摘Objective: Acupuncture has a definite therapeutic effect on chronic obstructive pulmonary disease(COPD), and the cholinergic anti-inflammatory pathway(CAP) has been shown to be involved in regulation of inflammation. In this study, we investigated whether electro-acupuncture(EA) affects the CAP in COPD.Methods: Sprague-Dawley rats were induced into COPD through exposure to cigarette smoke combined with lipopolysaccharide. EA treatment was applied at Zusanli(ST36) and Feishu(BL13) points for 30 min/d for 7 d. Seventy-two rats were randomly divided into six study groups, including normal, normal + EA,normal + α-bungarotoxin(a-BGT)(the antagonist of the nicotinic acetylcholine receptor a7 subunit(a7 nAChR)) + EA, COPD, COPD + EA, and COPD + α-BGT + EA. Lung function, pathology and vagus nerve discharge were tested. The levels of acetylcholine(ACh), acetylcholinesterase(AChE), interleukin-6(IL-6) and tumor necrosis factor-a(TNF-a) in bronchoalveolar lavage fluid(BALF) and lung tissue were measured by enzyme-linked immunosorbent assay. The mRNA and protein expression and immunoreactivity of a7 nAChR and its postreceptor inflammation signal pathway, including janus kinase 2(JAK2), signal transducers and activators of transcription 3(STAT3), nuclear factor-KB(NF-κB), were observed by quantitative reverse transcription-polymerase chain reaction, Western blot and immunohistochemistry.Results: Compared with normal rats, there were a significant decline in lung function and discharge of the vagus nerve(P < 0.01), a marked sign of lung inflammation and an increase of ACh, AChE, IL-6 and TNF-a level in BALF or lung tissue(P < 0.05, P < 0.01) and higher expression of a7 nAChR, JAK2, STAT3 and NF-κB(P<0.05, P<0.01) in the COPD rats. In rats receiving EA, the lung function and vagal discharge were enhanced(P < 0.01), lung inflammation was improved and the levels of ACh, AChE, IL-6 and TNF-a were decreased(P<0.01). Further, the expression of a7 nAChR, JAK2, STAT3 and NF-κB was downregulated(P < 0.05, P < 0.01). However, the above effects of EA were blocked in rats injected with α-BGT(P < 0.01).Conclusion: EA treatment can reduce the lung inflammatory response and improve lung function in COPD, which may be related to its involvement in the regulation of CAP. | Xin-fang Zhang Shui-ying Xiang Wen-ye Geng Wen-juan Cong Jing Lu Chuan-wei Jiang Kun Wang Zi-bing Liu | 2018 | Journal of Integrative Medicine2018，16，6： | 32 |

| 13 | Human urokinase-type plasminogen activator gene-modifiedbone marrow-derived mesenchymal stem cells attenuateliver fibrosis in rats by down-regulating the Wnt signalingpathway显示文摘AIM: To evaluate the therapeutic effects of bone marrow-derived mesenchymal stem cells(BMSCs) with human urokinase-type plasminogen activator(u PA) on liver fibrosis, and to investigate the mechanism of gene therapy.METHODS: BMSCs transfected with adenovirusmediated human urokinase plasminogen activator(Adu PA) were transplanted into rats with CCl4-induced liver fibrosis. All rats were sacrificed after 8 wk, and their serum and liver tissue were collected for biochemical, histopathologic, and molecular analyzes. The degree of liver fibrosis was assessed by hematoxylin and eosin or Masson's staining. Western blot and quantitative reverse transcription-polymerase chain reaction were used to determine protein and m RNA expression levels.RESULTS: Serum levels of alanine aminotransferase, aminotransferase, total bilirubin, hyaluronic acid, laminin, and procollagen type Ⅲ were markedly decreased, whereas the levels of serum albumin were increased by u PA gene modified BMSCs treatment. Histopathology revealed that chronic CCl4-treatment resulted in significant fibrosis while u PA gene modified BMSCs treatment significantly reversed fibrosis. By quantitatively analysing the fibrosis area of liver tissue using Masson staining in different groups of animals, we found that model animals with CCl4-induced liver fibrosis had the largest fibrotic area(16.69% ± 1.30%), while fibrotic area was significantly decreased by BMSCs treatment(12.38% ± 2.27%) and was further reduced by u PA-BMSCs treatment(8.31% ± 1.21%). Both protein and m RNA expression of β-catenin, Wnt4 and Wnt5 a was down-regulated in liver tissues following u PA gene modified BMSCs treatment when compared with the model animals.CONCLUSION: Transplantation of u PA gene modified BMSCs suppressed liver fibrosis and ameliorated liver function and may be a new approach to treating liver fibrosis. Furthermore, treatment with u PA gene modified BMSCs also resulted in a decrease in expression of molecules of the Wnt signaling pathway. | Zhi-Gang Ma Xiao-Dan Lv Ling-Ling Zhan Lan Chen Qi-Yuan Zou Ji-Qiao Xiang Jiao-Li Qin Wei-Wei Zhang Zhao-Jing Zeng Hui Jin Hai-Xing Jiang Xiao-Ping Lv | 2016 | World Journal of Gastroenterology2016，22，6： | 21 |
| 14 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020，7，9： | 20 |

| 17 | Cancer stem cell markers correlate with early recurrence and survival in hepatocellular carcinoma显示文摘AIM:To investigate whether expression of cancer stem cell(CSC)markers is associated with recurrence and survival in hepatocellular carcinoma(HCC)patients.METHODS:A consecutive series of 90 HCC patients who underwent curative hepatectomy between April2007 and April 2009 were analyzed.Of the 90 patients,38(42%)experienced recurrence within two years of surgery.To adjust for baseline differences between this early recurrence group and the other patients,propensity-score matching was used to generate 25 pairs of patients.Immunohistochemistry was used to compare expression of CD133,CD90,and epithelial cell adhesion molecule(EpCAM)in liver tissues from propensity score-matched patients and from 10 healthy adults.Associations of the three markers with HCC,clinicopathological characteristics,early recurrence,and survival time were explored.RESULTS:The expression of all three CSC markers was significantly higher in HCC tissue than in healthy liver tissue(P<0.001 for all).Among the HCC clinicopathology characteristics examined,the absence of tumor capsule was associated with CD133 expression(P=0.005);higher histopathology grade and larger tumor size were associated with CD90 expression(P=0.010 and 0.034,respectively);and elevated serum alpha-fetoprotein levels were associated with EpCAM expression(P=0.021).Expression of CD90 and EpCAM was significantly higher in the early recurrence group than in other patients(P=0.001 and 0.045,respectively),whereas CD133 expression was not significantly different between the two groups(P=0.440).Multivariate analysis identified only CD90 expression as significantly associated with early recurrence.Log-rank analysis identified expression of both CD90 and EpCAM as significantly associated with survival time of HCC patients.Cox regression identified EpCAM expression as an independent predictor of survival time.CONCLUSION:Expression of CD133,CD90,and EpCAM CSC markers may be linked to HCC tumor onset and/or progression.In addition,EpCAM expression is associated with shorter survival time,while CD90 expression is associated with early HCC recurrence. | Zhe Guo Le-Qun Li Jing-Hang Jiang Chao Ou Li-Xia Zeng Bang-De Xiang | 2014 | World Journal of Gastroenterology2014，20，8： | 18 |
| 18 | Blood neutrophil-lymphocyte ratio predicts survival after hepatectomy for hepatocellular carcinoma: A propensity score-based analysis显示文摘AIM: To investigate whether an elevated preoperative neutrophil-to-lymphocyte ratio(NLR) can predict poor survival in patients with hepatocellular carcinoma(HCC).METHODS: We retrospectively reviewed 526 patients with HCC who underwent surgery between 2004 and 2011.RESULTS: Preoperative NLR ≥ 2.81 was an independent predictor of poor disease-free survival(DFS, P < 0.001) and overall survival(OS, P = 0.044). Compared with patients who showed a preoperative NLR < 2.81 and postoperative increase, patients who showed preoperative NLR ≥ 2.81 and postoperative decrease had worse survival(DFS, P < 0.001; OS, P < 0.001). Among patients with preoperative NLR ≥ 2.81, survival was significantly higher among those showing a postoperative decrease in NLR than among those showing an increase(DFS, P < 0.001; OS, P < 0.001). When elevated, alpha-fetoprotein(AFP) provided no prognostic information, and so preoperative NLR ≥ 2.81 may be a good complementary indicator of poor OS whenever AFP levels are low or high.CONCLUSION: Preoperative NLR ≥ 2.81 may be an indicator of poor DFS and OS in patients with HCC undergoing surgery.

| 19 | Effects of particle size on crushing and deformation behaviors of rockfill materials显示文摘Strength and deformation behaviors of rockfill materials,key factors for determining the stability of dams,pertain strongly to the grain crushing characteristics.In this study,single-particle crushing tests were carried out on rockfill materials with nominal particle diameters of 2.5 mm,5 mm and 10 mm to investigate the particle size effect on the single-particle strength and the relationship between the characteristic stress and probability of non-failure.Test data were found to be described by the Weibull distribution with the Weibull modulus of 3.24.Assemblies with uniform nominal grains were then subjected to one-dimensional compression tests at eight levels of vertical stress with a maximum of 100 MPa.The yield stress in one-dimensional compression tests increased with decreasing the particle size,which could be estimated from the single-particle crushing tests.The void ratio-vertical stress curve could be predicted by an exponential function.The particle size distribution curve increased obviously with applied stresses less than 16 MPa and gradually reached the ultimate fractal grading.The relative breakage index became constant with stress up to 64 MPa and was obtained from the ultimate grading at the fractal dimension(a?2:7).A hyperbolical function was also found useful for describing the relationship between the relative breakage index and input work during one-dimensional compression tests. | Yang Xiao Minqiang Meng Ali Daouadji Qingsheng Chen ZhijunWu Xiang Jiang | 2020 | Geoscience Frontiers2020，11，2： | 17 |
| 20 | COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented. | Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu | 2021 | China CDC weekly2021，3，21： | 16 |
