| 1 | Double contrast-enhanced two-dimensional and three-dimensional ultrasonography for evaluation of gastric lesions显示文摘AIM:To investigate the value of two-dimensional(2D) and three-dimensional(3D) double contrast-enhanced ultrasonography(DCUS) imaging for evaluation of gastric lesions.METHODS:2D and 3D DCUS imaging with both oral and intravenous administrations of contrast agents was used to assess gastroscopiclly-confirmed gastric lesions in 46 patients with benign and malignant diseases.Initially,liquid-based ultrasound contrast agent(Xinzhang) was given orally at dose of 500-600 mL for conventional ultrasound examination of the gastric lesions,and then a microbubble-based contrast agent(SonoVue) was injected intravenously at dose of 1.2-2.4 mL in bolus fashion to assess the perfusion pattern of the lesions using contrast imaging modes.The parameters derived from time-intensity curves including the arrival time(AT),time to peak(TTP),peak intensity(PI) and enhanced intensity(EI) were measured on the 2D DCUS imaging.3D DCUS of the lesions was acquired to demonstrate the value of this imaging mode.RESULTS:There were 22 cases with benign lesions including chronic gastritis(n = 5),gastric ulcer(n = 9),gastric polyps(n = 3),gastric stromal tumors(n = 5),and 24 cases with malignant lesions including gastric cancer(n = 20),gastric cardia carcinoma(n = 3) and post-operative recurrent gastric cancer(n = 1) in the study.The oral contrast-enhanced ultrasonography(CEUS) imaging of the stomach clearly demonstrated the anatomy of the stomach and morphologic features of gastric lesions.With optimal scanning window and imaging display under oral CEUS,intravenous CEUS clearly showed the perfusion of gastric lesions with various characteristic manifestations.Both 2D and 3D DCUS images clearly demonstrated normal gastric wall as a three-layer structure,from the inside out,hyperechoic mucosa,hypoechoic muscularis and hyperechoic serosa,respectively.There were statistical significant differences of AT(8.68 ± 2.06 vs 10.43 ± 2.75,P = 0.017),PI(34.64 ± 6.63 vs 29.58 ± 8.22,P = 0.023) and EI(29.72 ± 6.69 vs 22.66 ± 7.01,P = 0.001) between malignant lesions and normal gastric wall.However,no differences of AT,PI and EI between benign lesions and normal gastric wall tissue were found.3D DCUS could intuitively display morphological features and vascularities of the lesions with multiplanar and volume views.3D DCUS imaging provided comprehensive information complementary to 2D imaging.The crater or wellhead appearances and feeding vessels as well as distorted nourishing vasculature of gastric carcinoma were better seen with 3D imaging than 2D imaging.CONCLUSION:DCUS imaging can simultaneously display the anatomic and perfusion features of gastric lesions.3D DCUS can provide additional information to 2D DCUS for evaluation of gastric lesions. | Hong Shi Xiu-Hua Yu Xin-Zhang Guo Yuan Guo Hong Zhang Bin Qian Zhang-Rui Wei Li Li Xian-Chen Wang Zi-Xiang Kong | 2012 | World Journal of Gastroenterology2012，18，31： | 36 |

| 3 | Sr-Nd isotopic compositions of the Changjiang sediments: Implications for tracing sediment sources显示文摘The suspended particulate and fine-grained floodplain sediments were collected from the main stream and tributaries of the Changjiang River for Sr-Nd isotopic measurements. The εNd(0) values gradually decrease downstream from -10.8 on average in the upper reaches to -12.3 in the lower reaches, whereas the 87Sr/86Sr ratios increase correspondingly, averaging 0.721899 and 0.725826 respectively in the upper and middle-lower reaches. The compositional variations primarily reflect the complex con- trols of provenance rocks, chemical weathering, and sediment characters between different catchments, among which the abnormal Sr-Nd isotopic compositions of the Yalong, Fujiang, Tuojiang and Yuanjiang rivers indicate the sediment provenance contributions from the Emeishan Basalt in the upper reaches and the old metamorphic and siliceous rocks in the middle-lower reaches. The Sr-Nd isotopic ratios of the Changjiang sediments can better reflect the average composition of weathered continental crust compared to other major rivers in the world because of the unique source rock types in the Changjiang drainage basin. The recognition of the Sr-Nd isotopic systematics of the Changjiang sediments will contribute to our understanding of the Changjiang evolution history and continental weathering processes during the Cenozoic, and also to reconstructing the paleoenvironmental changes in East China and the marginal seas. | YANG ShouYe1?, JIANG ShaoYong2, LING HongFei2, XIA XiaoPing3, SUN Min3 & WANG DeJie4 1 State Key Laboratory of Marine Geology, Tongji University, Shanghai 200092, China 2 State Key Laboratory for Mineral Deposit Research, Nanjing University, Nanjing 210093, China 3 Departmen of Earth Sciences, The University of Hong Kong, Hong Kong SAR, China 4 Development Research Center, China Geological Survey, Beijing 100083, China | 2007 | Science China Earth Sciences2007，50，10： | 32 |
| 4 | The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity. | Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping | 2016 | Biomedical and Environmental Sciences2016，29，1： | 29 |
| 5 | Environmental records of lacustrine sediments in different time scales:Sediment grain size as an example显示文摘Sediment grain size is a conventional proxy of climatic changes. Larger sediment grain size is often interpreted to indicate dry climate during lower lake level while smaller sedi- ment grain size implies wet climate during higher lake level. Through detailed study on sediment grain sizes in Lake Erhai and Lake Chenghai, this paper reveals the different indication signifi- cances of sediment grain sizes in different time scales, different resolution investigations. For long time-scale and low resolution (102a or 103a) studies, larger sediment grain size indicates lower lake level, smaller lake area and drier climate while smaller sediment grain size indicates higher lake level, larger lake area and wetter climate. For short time-scale and high resolution (a or 10a) studies, larger sediment grain size reflects more rainfall and wetter climate while smaller sediment grain size reflects less rainfall and drier climate. Environmental information revealed by lacustrine sediment records is often different in different time scales because of the variance of sedimentation resolution, sampling resolution and dating precision. Therefore, paleoclimate im- plications of environmental proxies in long time-scale and low resolution investigations could not be mechanically applied to short time-scale and high resolution studies. Only after synthetically analyzing the influence manner and extent of all factors on the sediment records in different time scales, can credible conclusions be obtained. | CHEN Jing’an1, WAN Guojiang1, David Dian Zhang2, ZHANG Feng1 & HUANG Ronggui1 1.

| 6 | Ability of Agrogyron elongatum to accumulate the single metal of cadmium, copper, nickel and lead and root exudation of organic acids显示文摘Agrogyron elongatum were grown in nutrient solution containing moderate to high amounts of separate heavy metal of Cd, Cu, Ni and Pb in a greenhouse for a 9-day. Cd, Cu, Ni and Pb generally led to decrease in the elongation of roots although the length of seedlings exposed to Cd and Pb at 0.05 and 0 5 mg/L showed to be slightly greater than that of controls. Of the four metals in the experiment, Pb was absorbed and accumulated to the highest level, with the concentrations of 92754 mg/kg dry weight (DW) in roots and 11683 mg/kg DW in shoots. Cd was moderately accumulated in Agrogyron elongatum, but the maximum bioaccumulation coefficients (BCs) for roots and shoots were observed. The patterns for Cu and Ni uptake and distribution in plants differed from those of Pb and Cd, as it was showed that the shoot accumulation of Cu and Ni was significantly higher than in roots. A. elongatum had the highest Ni concentration in shoots (30261 mg/kg DW) at the external concentration of 250 mg/L. Cu ranked second, with a shoot concentration of 12230 mg/kg DW when 50 mg/L Cu in solution was applied. For the four trace elements tested, the highest concentrations in shoots decreased by the order of Ni>Cu>Pb>Cd (mg/kg DW), and those in roots were Pb>Cd>Ni>Cu (mg/kg DW). Malic, oxalic and citric acids exuded by roots exposed to 1 and 50 mg/L of the metals were detected. Release of organic acids from plants significantly differed among the metal treatments. Cu was most effectively in inducing root exudation of the three types of organic acids. Cd, and Ni were also the inducers of secretion of malic and oxalic acids. With reference of Pb, a small amounts of malic and oxalic acids were detected in the root exudates, but few quantities of citric acid were found. However, no correlation between alternations in root exudation of organic acids and metal accumulation could be established. | YANG Hong 1, Jongathan W.C.Wong 2, YANG Zhi min\+1, ZHOU Li xiang 1(1.

| 10 | Expediting redox kinetics of sulfur species by atomic-scale electrocatalysts in lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S)batteries have extremely high theoretical energy density that make them as promising systems toward vast practical applications.Expediting redox kinetics of sulfur species is a decisive task to break the kinetic limitation of insulating lithium sulfide/disulfide precipitation/dissolution.Herein,we proposed a porphyrinderived atomic electrocatalyst to exert atomic-efficient electrocatalytic effects on polysulfide intermediates.Quantifying electrocatalytic efficiency of liquid/solid conversion through a potentiostatic intermittent titration technique measurement presents a kinetic understanding of specific phase evolutions imparted by the atomic electrocatalyst.Benefiting from atomically dispersed“lithiophilic”and“sulfiphilic”sites on conductive substrates,the finely designed atomic electrocatalyst endows Li–S cells with remarkable cycling stablity(cyclic decay rate of 0.10%in 300 cycles),excellent rate capability(1035 mAh g−1 at 2 C),and impressive areal capacity(10.9 mAh cm−2 at a sulfur loading of 11.3 mg cm−2).The present work expands atomic electrocatalysts to the Li–S chemistry,deepens kinetic understanding of sulfur species evolution,and encourages application of emerging electrocatalysis in other multielectron/multiphase reaction energy systems. | Bo-Quan Li Long Kong Chang-Xin Zhao Qi Jin Xiao Chen Hong-Jie Peng Jin-Lei Qin Jin-Xiu Chen Hong Yuan Qiang Zhang Jia-Qi Huang | 2019 | InfoMat2019，1，4： | 18 |
| 11 | Sedimentary Evolution of the Holocene Subaqueous Clinoform off the Southern Shandong Peninsula in the Western South Yellow Sea显示文摘Based on the stratigraphic sequence formed since the last glaciation and revealed by 3000 km long high-resolution shallow seismic profiles and the core QDZ03 acquired recently off the southern Shandong Peninsula, we addressed the sedimentary characteristics of a Holocene subaqueous clinoform in this paper. Integrated analyses were made on the core QDZ03, including sedimentary facies, sediment grain sizes, clay minerals, geochemistry, micro paleontology, and AMS 14 C dating. The result indicates that there exists a Holocene subaqueous clinoform, whose bottom boundary generally lies at 15–40 m below the present sea level with its depth contours roughly parallel to the coast and getting deeper seawards. The maximum thickness of the clinoform is up to 22.5 m on the coast side, and the thickness contours generally spread in a banded way along the coastline and becomes thinner towards the sea. At the mouths of some bays along the coast, the clinoform stretches in the shape of a fan and its thickness is evidently larger than that of the surrounding sediments. This clinoform came into being in the early Holocene(about 11.2 cal kyr BP) and can be divided into the lower and upper depositional units(DU 2 and DU 1, respectively). The unit DU 2, being usually less than 3 m in thickness and formed under a low sedimentation rate, is located between the bottom boundary and the Holocene maximum flooding surface(MFS), and represents the sediment of a post-glacial transgressive systems tract; whereas the unit DU 1, the main body of the clinoform, sits on the MFS, belonging to the sediment of a highstand systems tract from middle Holocene(about 7–6 cal kyr BP) to the present. The provenance of the clinoform differs from that of the typical sediments of the Yellow River and can be considered as the results of the joint contribution from both the Yellow River and the proximal coastal sediments of the Shandong Peninsula, as evidenced by the sediment geochemistry of the core. As is controlled mainly by coactions of multiple factors such as the Holocene sea-level changes, sediment supplies and coastal dynamic conditions, the development of the clinoform is genetically related with the synchronous clinoform or subaqueous deltas around the northeastern Shandong Peninsula and in the northern South Yellow Sea in the spatial distribution and sediment provenance, as previously reported, with all of them being formed from the initial stage of the Holocene up to the present. | QIU Jiandong LIU Jian SAITO Yoshiki YANG Zigeng YUE Baojing WANG Hong KONG Xianghuai | 2014 | Journal of Ocean University of China2014，13，5： | 17 |

| 13 | THE IMPROVEMENT OF ELECTRON FIELD EMISSION FROM AMORPHOUS CARBON FILMS DUE TO HYDROGEN PLASMA CHEMICAL ANNEALING EFFECT显示文摘Hydrogenated amorphous carbon films were fabricated by using layer-by-layer deposition method and hydrogen dilution method in a small d.c.-assisted plasma enhanced chemical vapor deposition system. It was found that the hydrogen plasma treatment could change the sp2/sp3 ratio to some extent by chemical etching. The improvements of field emission characteristics were observed compared with that from conventionally deposited a-C films, which can be attributed to the large field enhancement effect due to the inhomogeneous distribution of nanometer scale sp2 clusters and the reduction of the surface emission barrier due to the hydrogen termination. | J.

| 15 | Sleep deprivation increase the expression of inducible heat shock protein 70 in rat gastric mucosa显示文摘AIM To .investigate if sleep deprivation is able to increase the expression of inducible heat shock protein 70 in gastric mucosa and its possible role in mucosal defense.METHODS Rats for sleep disruption were placed inside a computerized rotating drum, gastric mucosa was taken from rats with 1, 3 and 7 d sleep deprivation. RT-PCR,immunohistochemistry and Western blotting were used to determine the expression of heat shock protein 70.Ethanol (500 mL@ L 1, I.g.) was used to induce gastric muceea damage.RESULTS RT-PCR, Western blotting and immunostaining confirmed that the sleep deprivation as a stress resulted in significantly greater expression of inducible heat shock protein 70 in gastric mucosa of rats. After the 500mL@ L-1 ethanol challenge, the ulcer area found in the rats with 7 d sleep deprivation (19.15 ± 4.2) mm2 was significantly lower (P<0.01) than the corresponding control (53.7 ± 8.1) mm2.CONCLUSION Sleep deprivation as a stress, in addition to lowering the gastric mucosal barrier, is able to stimulate the expression of inducible heat shock protein 70 in gastric mucosa of rats, the heat shock protein 70 may play an important role in gastric mucosal protection. | Xi-Zhong Shen Marcel W.L.

| 16 | Characteristics of the microbial communities in the integrated vertical-flow constructed wetlands显示文摘Microorganisms play an important role in removing pollutants from constructed wetlands.We investigated the microbial characteristics in a novel integrated vertical-flow constructed wetland(IVCW) ,which has been in operation in Wuhan,China since 1998.We used phospholipid fatty acid(PLFA) and amoA gene to analyze the structure and diversity of the microbial community within the IVCW.PLFA results suggested that the amount of bacterial PLFA was significantly higher than that of fungal PLFA,but the total microbial biomass represented by PLFA index was low in the system.Microbial spatial distribution showed significantly higher bacterial(both G+and G-) and fungal biomass in the surface than in the subsurface layers.The ratios of monounsaturated to branched PLFA demonstrated that an anaerobic layer sandwiched by two aerobic layers existed in the IVCW,consistent with the redox potential results.Analysis of the amoA revealed the presence of Nitrosomonas-like sequences in the surface substrate of the downflow chamber and apparent diversities of ammonia-oxidizing bacteria in the system.These results suggest that microorganisms,despite their relatively low biomass,have inhabited the IVCW,and the results will offer some valuable information on microbe to system designers and managers. | ZHOU Qiaohong,HE Feng,Zhang Liping,WANG Yanfen,WU Zhenbin State Key Laboratory of Freshwater Ecology and Biotechnology,Institute of Hydrobiology,Chinese Academy of Sciences,Wuhan 430072,China Department of Biology and Chemistry,City University of Hong Kong | 2009 | Journal of Environmental Sciences2009，21，9： | 14 |

| 18 | High-speed colour-converting photodetector with all-inorganic CsPbBr_(3) perovskite nanocrystals for ultraviolet light communication显示文摘Optical wireless communication(OWC)using the ultra-broad spectrum of the visible-to-ultraviolet(UV)wavelength region remains a vital field of research for mitigating the saturated bandwidth of radio-frequency(RF)communication.However,the lack of an efficient UV photodetection methodology hinders the development of UV-based communication.The key technological impediment is related to the low UV-photon absorption in existing silicon photodetectors,which offer low-cost and mature platforms.To address this technology gap,we report a hybrid Sibased photodetection scheme by incorporating CsPbBr_(3) perovskite nanocrystals(NCs)with a high photoluminescence quantum yield(PLQY)and a fast photoluminescence(PL)decay time as a UV-to-visible colourconverting layer for high-speed solar-blind UV communication.The facile formation of drop-cast CsPbBr_(3) perovskite NCs leads to a high PLQY of up to ~73% and strong absorption in the UV region.With the addition of the NC layer,a nearly threefold improvement in the responsivity and an increase of ~25% in the external quantum efficiency(EQE)of the solar-blind region compared to a commercial silicon-based photodetector were observed.Moreover,timeresolved photoluminescence measurements demonstrated a decay time of 4.5 ns under a 372-nm UV excitation source,thus elucidating the potential of this layer as a fast colour-converting layer.A high data rate of up to 34 Mbps in solar-blind communication was achieved using the hybrid CsPbBr_(3)-silicon photodetection scheme in conjunction with a 278-nm UVC light-emitting diode(LED).These findings demonstrate the feasibility of an integrated high-speed photoreceiver design of a composition-tuneable perovskite-based phosphor and a low-cost silicon-based photodetector for UV communication. | Chun Hong Kang Ibrahim Dursun Guangyu Liu Lutfan Sinatra Xiaobin Sun Meiwei Kong Jun Pan Partha Maity Ee-Ning Ooi Tien Khee Ng Omar F.Mohammed Osman M.Bakr Boon S.Ooi | 2019 | Light(Science & Applications)2019，8，1： | 14 |
| 19 | Empirical likelihood confidence regions of the parameters in a partially linear single-index model显示文摘In this paper, a partially linear single-index model is investigated, and three empirical log-likelihood ratio statistics for the unknown parameters in the model are suggested. It is proved that the proposed statistics are asymptotically standard chi-square under some suitable conditions, and hence can be used to construct the confidence regions of the parameters. Our methods can also deal with the confidence region construction for the index in the pure single-index model. A simulation study indicates that, in terms of coverage probabilities and average areas of the confidence regions, the proposed methods perform better than the least-squares method. | XUE Liugen~1 & ZHU Lixing~2 1.
