3Anisotropic 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

9Induces Resistance Against Fusarium and Pink Rots by Acibenzolar-S-Methyl in Harvested Muskmelon (cv.Yindi)显示文摘Acibenzolar-S-methyl (ASM) is a chemical activator of systematic resistance in many plants. The effect of preharvest and postharvest application of ASM was evaluated for its ability to induce resistance in muskmelon fruit. The results indicated that 50 and 100 mg L-1 ASM or 1 mL L-1 imazalil at 1 week or 1 day before harvest were effective in reducing the lesion area with 100 mg L-1 ASM the most effective. No treatment inhibited the infection rate. The postharvest results showed that 50 and 100 mg L-1 ASM,and 0.1 mL L-1 imazalil were effective in reducing the lesion area with 100 mg L-1 ASM the most effective. No treatment inhibited the infection rate. There was a clear time-dependent response of the fruit to postharvest ASM treatment,in which treatments applied 1,3,and 5 day before inoculation provided the best results. ASM did not demonstrate any fungicide effect in vitro and suppressed lesion area in treated muskmelons,indicating that disease resistance was induced. The protection of ASM was associated with the activation of peroxidase (POD) in treated muskmelons.GE Yong-hong BI Yang LI Xuan LI Mei 2008Agricultural Sciences in China2008,7,1:19
10Connective tissue diseases in primary biliary cirrhosis:A population-based cohort study显示文摘AIM:To establish the frequency and clinical features of connective tissue diseases(CTDs)in a cohort of Chinese patients with primary biliary cirrhosis(PBC).METHODS:Three-hundred and twenty-two Chinese PBC patients were screened for the presence of CTD,and the systemic involvement was assessed.The differences in clinical features and laboratory findings between PBC patients with and without CTD were documented.The diversity of incidence of CTDs in PBC of different countries and areas was discussed.For the comparison of normally distributed data,Student’s t test was used,while non-parametric test(Wilcoxon test)for the non-normally distributed data and 2×2χ2or Fisher’s exact tests for the ratio.RESULTS:One-hundred and fifty(46.6%)PBC patients had one or more CTDs.The most common CTD was Sj gren’s syndrome(SS,121 cases,36.2%).There were nine cases of systemic sclerosis(SSc,2.8%),12of systemic lupus erythematosus(SLE,3.7%),nine of rheumatoid arthritis(RA,2.8%),and 10 of polymyositis(PM,3.1%)in this cohort.Compared to patients with PBC only,the PBC+SS patients were more likely to have fever and elevated erythrocyte sedimentation rate(ESR),higher serum immunoglobulin G(IgG)levels and more frequent rheumatoid factor(RF)and interstitial lung disease(ILD)incidences;PBC+SSc patients had higher frequency of ILD;PBC+SLE patients had lower white blood cell(WBC)count,hemoglobin(Hb),platelet count,γ-glutamyl transpeptidase and immunoglobulin M levels,but higher frequency of renal involvement;PBC+RA patients had lower Hb,higher serum IgG,alkaline phosphatase,faster ESR and a higher ratio of RF positivity;PBC+PM patients had higher WBC count and a tendency towards myocardial involvement.CONCLUSION:Besides the common liver manifestation of PBC,systemic involvement and overlaps with other CTDs are not infrequent in Chinese patients.When overlapping with other CTDs,PBC patients manifested some special clinical and laboratory features which may have effect on the prognosis.Li Wang Feng-Chun Zhang Hua Chen Xuan Zhang Dong Xu Yong-Zhe Li Qian Wang Li-Xia Gao Yun-Jiao Yang Fang Kong Ke Wang 2013World Journal of Gastroenterology2013,19,31:18
11The influence of stage at diagnosis and molecular subtype on breast cancer patient survival: a hospital.based multi.center study显示文摘Background: Stage at diagnosis and molecular subtype are important clinical factors associated with breast cancer patient survival. However, subgroup survival data from a large study sample are limited in China.To estimate the survival differences among patients with different stages and various subtypes of breast cancer, we conducted a hospital-based multi-center study on breast cancer in Beijing, China.Methods: All resident patients diagnosed with primary, invasive breast cancer between January 1,2006 and December 31,2010 from four selected hospitals in Beijing were included and followed up until December 31,2015. Hospitalbased data of stage at diagnosis, hormone receptor status, and selected clinical characteristics, including body mass index(BMI), menopausal status, histological grade, and histological type, were collected from the medical records of the study subjects. Overall survival(OS) and cancer-specific survival(CSS) were estimated. Cox proportional hazards models were employed to evaluate the associations of stage at diagnosis and molecular subtype with patient survival.Results: The 5-year OS and CSS rates for all patients were 89.4% and 90.3%. Survival varied by stage and molecular subtype. The 5-year OS rates for patients with stage I, Ⅱ, Ⅲ, and IV diseases were 96.5%, 91.6%, 74.8%, and 40.7%,respectively, and the corresponding estimates of 5-year CSS rates were 97.1%, 92.6%, 75.6%, and 42.7%, respectively.The 5-year OS rates for patients with luminal A, luminal B, HER2, and triple-negative subtypes of breast cancer were92.6%, 88.4%, 83.6%, and 82.9%, respectively, and the corresponding estimates of 5-year CSS rates were 93.2%, 89.1 %,85.4%, and 83.5%, respectively. Multivariate analysis showed that stage at diagnosis and molecular subtype were important prognostic factors for breast cancer.Conclusions: Survival of breast cancer patients varied significantly by stage and molecular subtype. Cancer screening is encouraged for the early detection and early diagnosis of breast cancer. More advanced therapies and health care policies are needed on HER2 and triple-negative subtypes.Tingting Zuo Hongmei Zeng Huichao Li Shuo Liu Lei Yang Changfa Xia Rongshou Zheng Fei Ma Lifang Liu Ning Wang Lixue Xuan Wanqing Chen 2017Chinese Journal of Cancer2017,36,11:18
12Soil Erosion Changes over the Past Five Decades in the Red Soil Region of Southern China显示文摘This paper reports the dynamic changes of soil and water loss in the red soil region of Southern China since the 1950s. The red soil region covers eight provinces: Jiangxi, Zhejiang, Fujian, Anhui, Hubei, Hunan, Guangdong and Hainan. From the 1950s to 1986, the annual rate of soil erosion increased by 3.4%. From 1986 to 1996 and from 1996 to 2000, the annual rates of soil erosion decreased by 2.0% and 0.32%, respectively. Field surveys showed that from 2000 to 2005, the area of soil and water loss decreased annually by 1.2%. This decrease was a result of large-scale erosion control activities across China. Although the eroded soil has been restored, the restoration process is very slow and full restoration will take a long time. Our report suggests that controlling soil and water loss is a challenging task, and additional measures must be taken to effectively control the soil erosion in the red soil region.LIANG Yin LI Decheng LU Xixi YANG Xuan PAN Xianzhang MU Huan SHI Deming ZHANG Bin 2010Journal of Mountain Science2010,7,1:18
13Blocking FSH inhibits hepatic cholesterol biosynthesis and reduces serum cholesterol显示文摘Menopause is associated with dyslipidemia and an increased risk of cardio-cerebrovascular disease.The classic view assumes that the underlying mechanism of dyslipidemia is attributed to an insufficiency of estrogen.In addition to a decrease in estrogen, circulating follicle-stimulating hormone (FSH)levels become elevated at menopause.In this study,we find that blocking FSH reduces serum cholesterol via inhibiting hepatic cholesterol biosynthesis.First,epidemiological results show that the serum FSH levels are positively correlated with the serum total cholesterol levels,even after adjustment by considering the effects of serum estrogen,in addition,the prevalence of hypercholesterolemia is significantly higher in peri-menopausal women than that in premenopausal women.Furthermore,we generated a mouse model of FSH elevation by intraperitoneally injecting exogenous FSH into ovariectomized (OVX)mice,in which a normal level of estrogen (E2)was maintained by exogenous supplementation. Consistently,the results indicate that FSH,independent of estrogen,increases the serum cholesterol level in this mouse model. Moreover,blocking FSH signaling by anti-FSHβ antibody or ablating the FSH receptor (FSHR)gene could effectively prevent hypercholesterolemia induced by FSH injection or high-cholesterol diet feeding.Mechanistically,FSH,via binding to hepatic FSHRs, activates the Gi2α/β-arrestin-2/Akt pathway and subsequently inhibits the binding of FoxO1 with the SREBP-2 promoter,thus preventing FoxO1 from repressing SREBP-2 gene transcription.This effect,in turn,results in the upregulation of SREBP-2,which drives HMGCR nascent transcription and de novo cholesterol biosynthesis,leading to the increase of cholesterol accumulation.This study uncovers that blocking FSH signaling might be a new strategy for treating hypercholesterolemia during menopause, particularly for women in peri-menopause characterized by FSH elevation only.Yanjing Guo Meng Zhao Tao Bo Shizhan Ma Zhongshang Yuan Wenbin Chen Zhao He Xu Hou Jun Liu Zhenhai Zhang Qiang Zhu Qiangxiu Wang Xiaoyan Lin Zhongli Yang Min Cui Lu Liu Yujie Li Chunxiao Yu Xiaoyi Qi Qian Wang Haiqing Zhang Qingbo Guan Lifang Zhao Shimeng Xuan Huili Yan Yanliang Lin Li Wang Qihang Li Yongfeng Song Ling Gao Jiajun Zhao 2019Cell Research2019,29,2:16

15Clinical signif icance of C-reactive protein values in antibiotic treatment for pyogenic liver abscess显示文摘AIM:To investigate the clinical signifi cance of C-reactive protein (CRP) values in determining the endpoint of antibiotic treatment for liver abscess after drainage. METHODS: The endpoints of antibiotic treatment in 46 patients with pyogenic liver abscess after complete percutaneous drainage were assessed by performing a retrospective study. After complete percutaneous drainage, normal CRP values were considered as the endpoint in 18 patients (experimental group), and normal body temperature for at least 2 wk were considered as the endpoints in the other 28 patients (control group). RESULTS:The duration of antibiotic treatment after complete percutaneous drainage was 15.83 ± 6.45 d and 24.25 ± 8.18 d for the experimental and the control groups, respectively (P=0.001), being significantly shorter in the experimental group than in the control group. The recurrence rate was 0% for both groups.However, we could not obtain the follow-up data about 3 patients in the control group. CONCLUSION: CRP values can be considered as an independent factor to determine the duration of the antibiotic treatment for pyogenic liver abscess after complete percutaneous drainage.Hai-Nv Gao Wen-Xia Yuan Mei-Fang Yang Hong Zhao Jian-Hua Hu Xuan Zhang Jun Fan Wei-Hang Ma 2010World Journal of Gastroenterology2010,16,38:14

17Impact of anthropogenic activities on the sediment microbial communities of Baiyangdian shallow lake显示文摘Microorganisms are recognized as sensors of external disturbance in freshwater ecosystems.In this study,sediment samples from regions with strong human activity interference(four sites),moderate human activity interference(five sites)and minor human activity interference(five sites)in Baiyangdian Lake were collected;and their physiological and chemical properties and heavy metals contents were analyzed.The structures of bacterial and fungal communities were tested using 16S ribosomal Ribonucleic Acid(rRNA)and Internal Transcribed Spacer 2(ITS2)high-throughput sequencing technologies.The results indicated that Proteobacteria was the most abundant bacterial phylum.Ascomycota,Basidiomycota and Ciliophora were the dominant phyla of fungi.Obvious differences of microbial genera among the three regions were observed,especially fungal genera.With intensified disturbance by human activities,the Simpson and Shannon indices of bacteria significantly decreased.The fungal communities were clustered into three groups in accordance with the different human disturbance levels.The bacterial communities of sediment samples under moderate and minor human disturbance appeared similar,but different from those under strong human disturbance.Redundancy analysis indicated that zinc,total phosphorus,copper,and lead were the dominant factors that influenced the bacterial community.Nitrifiers and sulfate-reducing bacteria were influenced by pH,nitrate(NO3 ),and total nitrogen.The fungal community was significantly affected by total phosphorus.This study reveals that sediment microbial community structures among different regions of a shallow lake are mainly impacted by human activities.Wenjun Wang Yujun Yi Yufeng Yang Yang Zhou Shanghong Zhang Xuan Wang Zhifeng Yang 2020International Journal of Sediment Research2020,35,2:14
