1Incidence and mortality of stomach cancer in China,2014显示文摘Objective: In this study,we aimed to estimate the updated incidence and mortality rate of stomach cancer based on the cancer registration data in 2014,collected by the National Central Cancer Registry of China(NCCRC).Methods: In 2017,339 registries' data were qualified based on the criteria of data quality control of the NCCRC.Cases of stomach cancer were retrieved from the national database.We estimated numbers of stomach cancer cases and deaths in China using age-specific rates and corresponding national population stratified by area,sex,agegroup(0,1–4,5–9,10–14,…,85+).Chinese standard population in 2000 and Segi's world population were applied for age-standardized incidence and mortality rates.Results: In 2014,410,400 new stomach cancer cases and 293,800 cancer-associated deaths were estimated to have occurred in China.The crude incidence rate of stomach cancer was 30.00/100,000,age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 19.62/100,000 and19.51/100,000,respectively.The crude mortality rate of stomach cancer was 21.48/100,000,age-standardized mortality rates by Chinese(ASMRC) and by world standard population(ASMRW) were 13.44/100,000 and13.30/100,000,respectively.Incidence and mortality rates in rural areas were both higher than that in urban areas.Stomach cancer has a strong relationship with gender and age.The disease has occurred more frequently among men than women with a male to female ratio of 2.4 for ASIRC.After age group of 40-44 years,incidence rates are substantially higher in men than in women,same pattern was seen for age-specific mortality rates.Conclusions: There is still a heavy burden of stomach cancer in China.The incidence and mortality patterns of stomach cancer show substantial gender and regional disparities.Great effort is needed to provide more accessible health services,sufficient financial resources,and adequate cancer-care infrastructure for the Chinese population,especially for people living in rural areas.Lei Yang Rongshou Zheng Ning Wang Yannan Yuan Shuo Liu Huichao Li Siwei Zhang Hongmei Zeng Wanqing Chen 2018Chinese Journal of Cancer Research2018,30,3:114
2Gastric cancer: Epidemiology, risk factors and prevention strategies显示文摘Gastric cancer(GC) is a global health problem, with more than 1 million people newly diagnosed with GC worldwide each year. GC is more prevalent in less developed countries than in more developed countries. About half of all GC cases worldwide occur in East Asia, notably China. Globally, overall incidence rates of GC are declining, which is potentially attributed to a decrease in Helicobacter pylori(H. pylori) infection and the use of refrigeration to preserve foods rather than salt. GC is a multifactorial disease, and its occurrence and development were impacted by environmental and genetic factors. H. pylori infection is the primary risk factor for GC, especially for non-cardia. The prognosis of GC is poor due to stages at the first diagnosis. The 5-year survival rate is less than 10% when patients are diagnosed at an advanced stage, but the rate is as high as 85% if patients are detected at an earlier stage. Endoscopic screening can potentially prevent GC by early diagnosis and early treatment and has been widely adopted in screening programs in East Asian countries, such as Japan and Korea. This review summarizes updated epidemiological aspects, risk factors, and prevention strategies of GC in recent years to help researchers determine the most effective intervention strategies for reducing risk of GC.Lei Yang Xiangji Ying Shuo Liu Guoqing Lyu Zekuan Xu Xi Zhang Huichao Li Qingyu Li Ning Wang Jiafu Ji 2020Chinese Journal of Cancer Research2020,32,6:52
3Programmable time-domain digital-coding metasurface for non-linear harmonic manipulation and new wireless communication systems显示文摘Optical non-linear phenomena are typically observed in natural materials interacting with light at high intensities, and they benefit a diverse range of applications from communication to sensing. However,controlling harmonic conversion with high efficiency and flexibility remains a major issue in modern optical and radio-frequency systems. Here, we introduce a dynamic time-domain digital-coding metasurface that enables efficient manipulation of spectral harmonic distribution. By dynamically modulating the local phase of the surface reflectivity, we achieve accurate control of different harmonics in a highly programmable and dynamic fashion, enabling unusual responses, such as velocity illusion. As a relevant application, we propose and realize a novel architecture for wireless communication systems based on the time-domain digital-coding metasurface, which largely simplifies the architecture of modern communication systems, at the same time yielding excellent performance for real-time signal transmission. The presented work, from new concept to new system, opens new pathways in the application of metamaterials to practical technology.Jie Zhao Xi Yang Jun Yan Dai Qiang Cheng Xiang Li Ning Hua Qi Jun Chen Ke Guo Dong Bai Shuo Liu Shi Jin Andrea Alù Tie Jun Cui 2019National Science Review2019,6,2:46
4Solid-state additive manufacturing and repairing by cold spraying:A review显示文摘High-performance metal additive manufacturing(AM) has been extensively investigated in recent year because of its unique advantages over traditional manufacturing processes. AM has been applied to form complex components of Ti, Fe or Ni alloys. However, for other nonferrous alloys such as Al alloys, Mg alloys and Cu alloys, AM may not be appropriate because of its melting nature during processing by laser electron beam, and/or arc. Cold spraying(CS) has been widely accepted as a promising solid-state coating technique in last decade for its mass production of high-quality metals and alloys, and/or metal matrix composites coatings. It is now recognized as a useful and powerful tool for AM, but the related research work has just started. This review summarized the literature on the state-of-the-art and problems for C as an AM and repairing technique.Wenya Li Kang Yang Shuo Yin Xiawei Yang Yaxin Xu Rocco Lupoi 2018Journal of Materials Science & Technology2018,34,3:35
5Anisotropic 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
6Broadband diffusion of terahertz waves by multi-bit coding metasurfaces显示文摘The terahertz region is a special region of the electromagnetic spectrum that incorporates the advantages of both microwaves and infrared light waves.In the past decade,metamaterials with effective medium parameters or gradient phases have been studied to control terahertz waves and realize functional devices.Here,we present a new approach to manipulate terahertz waves by using coding metasurfaces that are composed of digital coding elements.We propose a general coding unit based on a Minkowski closed-loop particle that is capable of generating 1-bit coding(with two phase states of 0 and 180°),2-bit coding(with four phase states of 0,90°,180°,and 270°),and multi-bit coding elements in the terahertz frequencies by using different geometric scales.We show that multi-bit coding metasurfaces have strong abilities to control terahertz waves by designing-specific coding sequences.As an application,we demonstrate a new scattering strategy of terahertz waves—broadband and wide-angle diffusion—using a 2-bit coding metasurface with a special coding design and verify it by both numerical simulations and experiments.The presented method opens a new route to reducing the scattering of terahertz waves.Li-Hua Gao Qiang Cheng Jing Yang Shao-Jie Ma Jie Zhao Shuo Liu Hai-Bing Chen Qiong He Wei-Xiang Jiang Hui-Feng Ma Qi-Ye Wen Lan-Ju Liang Biao-Bing Jin Wei-Wei Liu Lei Zhou Jian-Quan Yao Pei-Heng Wu Tie-Jun Cui 2015Light(Science & Applications)2015,4,1:31
7CLINICAL APPLICATION OF BODY DIFFUSION WEIGHTED MR IMAGING IN THE DIAGNOSIS AND PREOPERATIVE N STAGING OF CERVICAL CANCER显示文摘Objective To evaluate the clinical impact of body diffusion weighted imaging (DWI) on the diagnosis and preoperative N staging of cervical cancer. Methods Twenty-four patients (mean age 37.9 years old) with proved cervical cancer by cervical biopsy and 24 female patients with other suspected pelvic abnormalities received preoperative body DWI scan. Results of body DWI were compared with pathological findings. The apparent diffusion coefficient (ADC) values of normal cervix and different pathological types of cervical cancer were compared. ADC value of normal or inflammatory lymph nodes was also compared with that of metastatic ones. Student's t test was used for statistical analysis. Results There were 5 adenocarcinomas and 19 epitheliomas showed with biopsy results, and DWI showed 21 cervical lesions out of them (87.5%). ADC values of the normal cervix (n = 24), epithelioma (n = 19), and adenocar- cinoma (n = 5) were (1.73 ± 0.31) ×10-3, (0.88 ± 0.22) ×10-3, and (1.08 ± 0.12) ×10-3 mm2/s, respectively. Statistical analysis showed significant difference in ADC value between normal cervical tissue and either tumor tissues (both P < 0.01). In patients had lymphadenectomy (n = 24), totally 67 lymph nodes including 16 metastatic lymph nodes were pathologically analyzed, and DWI showed 66 (98.5%) out of them. ADC values of normal/inflammatory and metastatic lymph nodes were (1.07 ± 0.16) ×10-3 and (0.77 ± 0.13) ×10-3 mm2/s (P < 0.01). Receiver operating characteristic (ROC) curve of ADC value of metastatic lymph node showed that area under curve was 0.961. Conclusions ADC value in cervical carcinoma is lower than that in normal cervix, and ADC may have predictive value in subtype discrimination. ADC value may improve the preoperative characterization of lymph node metastasis. And at least abdominal and pelvic DWI scan is suggested for N staging evaluation in such patients.Hua-dan Xue Shuo Li Fei Sun Hong-yi Sun Zheng-yu Jin Jia-xin Yang Mei Yu 2008Chinese Medical Sciences Journal2008,23,3:28
8A Survey of 16 Rare Earth Elements in the Major Foods in China显示文摘Objective The aim of this survey was to inves gate the level of contamina on of the most consumed foods in China with 16 rare earth elements (REEs),and to provide the basic data for establishing and revising food safety standards for REEs.Methods Sixteen REEs in foods were measured by induc vely coupled plasma-mass spectrometry (ICP-MS) in the labs of the Centers for Disease Control and Preven on of four provinces and two municipali es,during 2009-2010.Results 1 231 samples were analyzed and 19 121 concentra on data of 16 REEs were collected.The REEs levels in the inves gated foods varied significantly.The concentra ons of cerium (Ce),dysprosium (Dy),y rium (Y),lanthanum (La),and neodymium (Nd) were rela vely high,while the remaining eleven REEs were at low levels.The mean values of total rare earth element oxides (REOs) in cereals,fresh vegetables,fresh aqua c products,fresh meats and eggs varied from 0.052 mg/kg to 0.337 mg/kg.Conclusion 16 REEs in the major foods were at very low contamina on levels in the inves gated regions.JIANG Ding Guo YANG Jie ZHANG Shuo YANG Da Jin 2012Biomedical and Environmental Sciences2012,25,3:28
9Air pollution characteristics and their relationship with emissions and meteorology in the Yangtze River Delta region during 2014–2016显示文摘With rapid economic growth and urbanization, the Yangtze River Delta(YRD) region in China has experienced serious air pollution challenges. In this study, we analyzed the air pollution characteristics and their relationship with emissions and meteorology in the YRD region during 2014–2016. In recent years, the concentrations of all air pollutants, except O3,decreased. Spatially, the PM2.5, PM10, SO2, and CO concentrations were higher in the northern YRD region, and NO2 and O3 were higher in the central YRD region. Based on the number of non-attainment days(i.e., days with air quality index greater than 100), PM2.5 was the largest contributor to air pollution in the YRD region, followed by O3, PM10, and NO2.However, particulate matter pollution has declined gradually, while O3 pollution worsened.Meteorological conditions mainly influenced day-to-day variations in pollutant concentrations. PM2.5 concentration was inversely related to wind speed, while O3 concentration was positively correlated with temperature and negatively correlated with relative humidity.The air quality improvement in recent years was mainly attributed to emission reductions.During 2014–2016, PM2.5, PM10, SO2, NOx, CO, NH3, and volatile organic compound(VOC)emissions in the YRD region were reduced by 26.3%, 29.2%, 32.4%, 8.1%, 15.9%, 4.5%, and0.3%, respectively. Regional transport also contributed to the air pollution. During regional haze periods, pollutants from North China and East China aggravated the pollution in the YRD region. Our findings suggest that emission reduction and regional joint prevention and control helped to improve the air quality in the YRD region.Tao Ma Fengkui Duan Kebin He Yu Qin Dan Tong Guannan Geng Xuyan Liu Hui Li Shuo Yang Siqi Ye Beiyao Xu Qiang Zhang Yongliang Ma 2019Journal of Environmental Sciences2019,31,9:26
10Increased globulin and its association with hemorrhagic transformation in patients receiving intra-arterial thrombolysis therapy显示文摘Previous studies have identified a diverse set of predisposing factors for the occurrence of hemorrhagic transformation(HT), but the independent clinical predictors of HT after intraarterial thrombolysis have not been determined.In this retrospective study, we investigated the characteristics of patients with or without HT who had received intra-arterial thrombolysis therapy, using biochemical analysis, renal function test, routine blood test, blood lipid test, coagulation blood test,liver function test, random blood glucose test, timewindow for intra-arterial thrombolysis, recanalization,National Institutes of Health Stroke Scale(NIHSS)score and systolic blood pressure before intra-arteria thrombolysis. The mortality rates were similar in the HT and non-HT groups(P = 0.944). In the singlefactor analysis, patients with a higher globulin leve(P <0.002), prothrombin time activity percentage(PTA; P = 0.026), and NIHSS score(P = 0.002),had a significantly increased risk of developing HT.In the multifactor logistic regression model involving globulin level, PTA, white blood cell count, and NIHSS score, the globulin level(P <0.001; OR,1.185; 95% confidence interval [CI], 1.090–1.288),PTA(P = 0.018; OR, 1.016; 95% CI, 1.003–1.029),white blood cell count(P = 0.025; OR, 1.097; 95%CI, 1.012–1.190) and NIHSS score(P = 0.003; OR,1.097; 95% CI, 1.031–1.166) were significantlyincreased in the HT group. The increase in globulin level is an independent risk factor for HT in patients receiving intra-arterial thrombolysis. The possible mechanisms may involve inflammatory cytokines, matrix metalloproteinase 9, and positive acute-phase reactants synthesized by the liver.Yingqi Xing Zhen-Ni Guo Shuo Yan Hang Jin Shouchun Wang Yi Yang 2014Neuroscience Bulletin2014,30,3:21
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

14Experimental Study of Wastewater Treatment of Reactive Dye by Phys-Chemistry Method显示文摘Wastewater, which involves easy-soluble reactive dyes, especially non-degradable dyes, is very difficult to decolor efficiently by normal processes such as coagulation process and biological treatment. The high chromaticity se- riously hinders the reuse of reactive dye waste water. In this paper, a new method by bentonite adsorption and coagulation (PAC) is employed for removing color from synthetic dye waste water which contains reactive red K-2G, K-RN blue, K-GR blue, X-3B red, K-GN orange, KB-3G yellow, K-2BP red, K-RN yellow and K-6G yellow. Bentonite pre- treated by 4% CTMAB and milled to 160 order screen is proven to the best decoloring agent. For a 100 mL reactive red K-2G sample (CODcr 400 mg/L, 25 000 chromaticity color), 0.5 g bentonite pretreated and 2.5 mL PAC is enough to decolor wastewater up to 99.92% and the sediment time is short. Non-degradable dyes such as active red X-3B and K-GN orange are declored completely as well. Raw sewage (low chromaticity color) is decolored completely at a ben-tonite dosage of 0.001g. More researches prove the high practical value of this process.YANG Yan-wu ZHOU Tong-ling QIAO Qi-cheng CHEN Shuo 2007Journal of China University of Mining and Technology2007,17,1:15
15Ammonium removal pathways and microbial community in GAC-sand dual media filter in drinking water treatment显示文摘A GAC-sand dual media filter(GSF) was devised as an alternative solution for drinking water treatment plant to tackle the raw water polluted by ammonium in place of expensive ozone-GAC processes or bio-pretreatments.The ammonium removal pathways and microbial community in the GSFs were investigated.The concentrations of ammonium,nitrite and nitrate nitrogen were monitored along the filter.Total inorganic nitrogen(TIN) loss occurred during the filtration.For 1 mg ammonium removal,the TIN loss was as high as 0.35 mg,DO consumption was 3.06 mg,and alkalinity consumption was 5.55 mg.It was assumed that both nitrification and denitrification processes occur in the filters to fit the TIN loss and low DO consumption.During the filtration,nitritation,nitrification and nitritation-anaerobic ammonium oxidation processes probably occur,while traditional nitrification and denitrification and simultaneous nitrification and denitrification processes may occur.In the GSFs,Nitrosomonas and Nitrospira are likely to be involved in nitrification processes,while Novosphingobium,Comamonadaceae and Oxalobacteraceae may be involved in denitrification processes.Shuo Feng Shuguang Xie Xiaojian Zhang Zhiyu Yang Wei Ding Xiaobin Liao Yuanyuan Liu Chao Chen 2012Journal of Environmental Sciences2012,24,9:14
16Development of real-time laser-scanning system to detect tree canopy characteristics for variable-rate pesticide application显示文摘Improving pesticide application efficiency is increasingly important in orchard spraying.In this study,a laser-scanning system was designed to acquire gridding volumes of a tree to quantify the geometry characteristics of the tree canopy in real-time.A laser-scanning sensor mounted on a linear guide was utilized to measure the structure of a target tree canopy.A computer was used to receive measurement data from the laser scanner and obtain the movement distance of the laser-scanning sensor from a controller.An algorithm written with VC#program was designed to calculate gridding volumes of trees by recognizing valid measurement data from the laser scanner.Laboratory evaluations were conducted on three kinds of regular objects,and the maximum relative errors of section volumes of the cuboid,triangular prism and cylinder objects were 3.3%,7.9%and 9.4%,respectively,which illustrated that the algorithm could calculate the section volumes in different parts of the objects with high accuracy.A conifer tree and an apple tree were chosen to verify detecting accuracy of the laser-scanning system at variable speeds and grid sizes.The variation coefficients of total volumes for each kind of the tree were 0.078 and 0.041,respectively,which indicated that the laser-scanning system could be applied to provide the gridding volumes of different canopy densities in real-time with good reliability for guiding a variable-rate sprayer.Cai Jichen Wang Xiu Song Jian Wang Songlin Yang Shuo Zhao Chunjiang 2017International Journal of Agricultural and Biological Engineering2017,10,6:14
17Influence of dexamethasone on mesenteric lymph node of rats with severe acute pancreatitis显示文摘AIM: To study the influence and mechanisms of dexamethasone on mesenteric lymph node of rats with severe acute pancreatitis (SAP). METHODS: The SAP rats were assigned to model, treated or sham-operated groups. The mortality, pathological changes of mesenteric lymph nodes, expression levels of NF-kB, P-selectin, Bax, Bcl-2 and caspase-3 protein and changes in apoptotic indexes in lymph nodes were observed at 3, 6 and 12 h after operation. The blood levels of endotoxin, superoxide dismutase (SOD), malondialdehyde (MDA), and endothelin-1 (ET-1) in blood were determined. RESULTS: SOD content, expression of Bax protein and apoptotic index were significantly higher in the treated group than in the model group at different time points (P < 0.05 or P < 0.01). Other blood-detecting indexes and histopathological scores of mesenteric lymphnodes were lower in the treated than in the model group (P < 0.05, P < 0.01 or P < 0.01). NF-kB protein expression was negative in all groups. Comparing P-selectin and caspase-3 expression levels among all three groups, there was no marked difference between the model and treated group. CONCLUSION: Dexamethasone can protect mesen-teric lymph nodes. The mechanism may be by reducing the content of inflammatory mediators in the blood and inducing lymphocyte apoptosis.Xi-Ping Zhang Hong-Miao Xu Yi-Yu Jiang Shuo Yu Yang Cai Bei Lu Qi Xie Tong-Fa Ju 2008World Journal of Gastroenterology2008,14,22:14
