3Positive impact of adding No.14v lymph node to D2 dissection on survival for distal gastric cancer patients after surgery with curative intent显示文摘Background:D2 lymphadenectomy has been increasingly regarded as standard surgical procedure for advanced gastric cancer(GC),while the necessity of No.14 v lymph node(14v) dissection for distal GC is still controversial.Methods:A total of 920 distal GC patients receiving at least a D2 lymph node dissection in Department of Gastric Cancer,Tianjin Medical University Cancer Institute and Hospital were enrolled in this study,of whom,243 patients also had the 14 v dissected.Other 677 patients without 14 v dissection were used for comparison.Results:Forty-five(18.5%) patients had 14 v metastasis.There was no significant difference in 3-year overall survival(OS) rate between patients with and without 14 v dissection.Following stratified analysis,in TNM stages I,II,IIIa and IV,14 v dissection did not affect 3-year OS;in contrast,patients with 14 v dissection had a significant higher 3-year OS than those without in TNM stages IIIb and IIIc.In multivariate analysis,14 v dissection was found to be an independent prognostic factor for GC patients with TNM stage IIIb/IIIc disease [hazard ratio(HR),1.568;95% confidence interval(CI):1.186-2.072;P=0.002].GC patients with 14 v dissection had a significant lower locoregional,especially lymph node,recurrence rate than those without 14 v dissection(11.7 % vs.21.1%,P=0.035).Conclusions:Adding 14 v to D2 lymphadenectomy may be associated with improved 3-year OS for distal GC staged TNM Ⅲb/Ⅲc.Yuexiang Liang Liangliang Wu Xiaona Wang Xuewei Ding Hongmin Liu Bin Li Baogui Wang Yuan Pan Rupeng Zhang Ning Liu Han Liang 2015Chinese Journal of Cancer Research2015,27,6:22

5Quantitative description of characteristics of high-capacity channels in unconsolidated sandstone reservoirs using in situ production data显示文摘Quantitative description of the high-capacity channels in unconsolidated sandstone reservoirs,into which water was injected to improve oil recovery,is a hot topic in the fi eld of reservoir development. This paper presents a novel approach to describing quantitatively the characteristics of connected macropores in unconsolidated sandstone reservoirs using in situ production data. Based on physical simulation for formation mechanisms of high capacity channels and interwell tracer test data,a mathematical model was established to describe high-capacity channels by grey correlation theory,glow mechanism of fluid in porous media and reservoir engineering,and a program was developed to describe quantitatively the channel characteristics. The predicted results were consistent with fi eld monitoring data(80%) ,so this model could be economically and effectively used to identify high-capacity channels.Wang Xuezhong Wang Jianyong Wang Chuanfei Zeng Liufang Liu Xuewei 2010Petroleum Science2010,7,1:15

9Improving CLM4.5 Simulations of Land–Atmosphere Exchange during Freeze–Thaw Processes on the Tibetan Plateau显示文摘Soil is heterogeneous and has different thermal and hydraulic properties, causing varied behavior in heat and moisture transport. Therefore, soil has an important effect on land–atmosphere interactions. In this study, an improved soil parameterization scheme that considers gravel and organic matter in the soil was introduced into CLM4.5(Community Land Model). By using data from the Zoige and Madoi sites on the Tibetan Plateau, the ability of the model to simultaneously simulate the duration of freeze–thaw periods, soil temperature, soil moisture, and surface energy during freeze–thaw processes, was validated. The results indicated that:(1) the new parameterization performed better in simulating the duration of the frozen, thawing, unfrozen, and freezing periods;(2) with the new scheme, the soil thermal conductivity values were decreased;(3) the new parameterization improved soil temperature simulation and effectively decreased cold biases;(4) the new parameterization scheme effectively decreased the dry biases of soil liquid water content during the freezing, completely frozen, and thawing periods, but increased the wet biases during the completely thawed period; and(5) the net radiation, latent heat flux, and soil surface heat flux of the Zoige and Madoi sites were much improved by the new organic matter and thermal conductivity parameterization.Siqiong LUO Xuewei FANG Shihua LYU Yu ZHANG Boli CHEN 2017Journal of Meteorological Research2017,31,5:13
10Orderly Porous Covalent Organic Frameworks-based Materials:Superior Adsorbents for Pollutants Removal from Aqueous Solutions显示文摘Covalent organic frameworks(COFs)are a new type of crystalline porous polymers known for chemical stability,excellent structural regularity,robust framework,and inherent porosity,making them promising materials for capturing various types of pollutants from aqueous solutions.This review thoroughly presents the recent progress and advances of COFs and COF-based materials as superior adsorbents for the efficient removal of toxic heavy metal ions,radionuclides,and organic pollutants.Information about the interaction mechanisms between various pollutants and COF-based materials are summarized from the macroscopic and microscopic standpoints,including batch experiments,theoretical calculations,and advanced spectroscopy analysis.The adsorption properties of various COF-based materials are assessed and compared with other widely used adsorbents.Several commonly used strategies to enhance COF-based materials’adsorption performance and the relationship between structural property and sorption ability are also discussed.Finally,a summary and perspective on the opportunities and challenges of COFs and COF-based materials are proposed to provide some inspiring information on designing and fabricating COFs and COF-based materials for environmental pollution management.Xiaolu Liu Hongwei Pang Xuewei Liu Qian Li Ning Zhang Liang Mao Muqing Qiu Baowei Hu Hui Yang Xiangke Wang 2021The Innovation2021,2,1:12
11Fractal model of lightning channel for simulating lightning strikes to transmission lines显示文摘How to accurately evaluate the direct-strike lightning protection is one of the key issues in the design of transmission lines. In this paper, three important issues in applying the fractal simulation to the lightning protection of transmission lines were discussed, including the criteria and implementation of upward leader inception, the connection with the magnitude of lightning current, and the calculation and control of fractal dimensions. Then we conducted the simulation iterately, leading to statistical results, which indicate that even if the transmission line satisfies the perfect shielding condition, shielding failure fault remains possible. Furthermore, we calculated the shielding failure fault rates of an EHV line with different ground obliquities and distribution of strike points over the interval between two neighboring towers along a UHV-DC line to find out the weak point of transmission-line lightning protection. This work provides a promising approach for improving the lightning protection property of transmission lines by optimizing the configuration of shielding wires and phase or pole conductors.HE JinLiang ZHANG XueWei DONG Lin ZENG Rong LIU ZeHong 2009Science China(Technological Sciences)2009,52,11:12
12Numerical simulation of bubble plumes in overlying water of gas hydrate in the cold seepage active region显示文摘To study the seismic responses produced by gas hydrate bubble plumes in the cold seepage active region, we constructed a plume water body model based on random medium theory and acoustic velocity model of bubble medium. The plume water body model was forward simulated by finite difference. Seismic records of single shot show the scattered waves produced by the plume. The scattered wave energy is strong where the plume exists. Where the scattered wave energy is stronger, the minimum of travel time is always above the plume, which has no relationship with the shot's position. Seismic records of shot gathers were processed by prestack time migration. The migration section shows that the scattered waves produced by plumes can be imaged distinctly with higher accuracy. These researches laid a foundation for further study on the seismic responses produced by plumes and provided a new approach for the identification of gas hydrate.LI CanPing LIU XueWei GOU LiMin WANG XiangChun YIN JunJie XIE ChengLiang 2013Science China Earth Sciences2013,56,4:11

15Decellularized extracellular matrix scaffolds:Recent trends and emerging strategies in tissue engineering显示文摘The application of scaffolding materials is believed to hold enormous potential for tissue regeneration.Despite the widespread application and rapid advance of several tissue-engineered scaffolds such as natural and synthetic polymer-based scaffolds,they have limited repair capacity due to the difficulties in overcoming the immunogenicity,simulating in-vivo microenvironment,and performing mechanical or biochemical properties similar to native organs/tissues.Fortunately,the emergence of decellularized extracellular matrix(dECM)scaffolds provides an attractive way to overcome these hurdles,which mimic an optimal non-immune environment with native three-dimensional structures and various bioactive components.The consequent cell-seeded construct based on dECM scaffolds,especially stem cell-recellularized construct,is considered an ideal choice for regenerating functional organs/tissues.Herein,we review recent developments in dECM scaffolds and put forward perspectives accordingly,with particular focus on the concept and fabrication of decellularized scaffolds,as well as the application of decellularized scaffolds and their combinations with stem cells(recellularized scaffolds)in tissue engineering,including skin,bone,nerve,heart,along with lung,liver and kidney.Xuewei Zhang Xi Chen Hua Hong Rubei Hu Jiashang Liu Changsheng Liu 2022Bioactive Materials2022,7,4:10
16Clopidogrel with aspirin in High- risk patients with Acute Non- disabling Cerebrovascular Events II (CHANCE-2): rationale and design of a multicentre randomised trial显示文摘Background In patients with a minor ischaemic stroke or transient ischaemic attack(TIA),separate trials have shown that dual antiplatelet therapy with clopidogrel plus aspirin(clopidogrel-aspirin)or ticagrelor plus aspirin(ticagrelor-aspirin)are more effective than aspirin alone in stroke secondary prevention.However,these two sets of combination have not been directly compared.Since clopidogrel was less effective in stroke patients who were CYP2C19 loss-of function(LOF)allele carriers,whether ticagrelor-aspirin is clinically superior to clopidogrel-aspirin in this subgroup of patients with stroke is unclear.Aim To describe the rationale and design considerations of the Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events(CHANCE-2)trial.Design CHANCE-2 is a randomised,double-blind,double-dummy,placebo-controlled,multicentre trial that compares two dual antiplatelet strategies for minor stroke or TIA patients who are CYP2C19 LOF allele carriers:ticagrelor(180 mg loading dose on day 1 followed by 90 mg twice daily on days 2-90)or clopidogrel(300 mg loading dose on day 1 followed by 75 mg daily on days 2-90),plus open-label aspirin with a dose of 75-300 mg on day 1 followed by 75 mg daily on day 2-21.All will be followed for 1 year.Study outcomes The primary efficacy outcome is any stroke(ischaemic or haemorrhagic)within 3 months and the primary safety outcome is any severe or moderate bleeding event within 3 months.Discussion The CHANCE-2 trial will evaluate whether ticagrelor-aspirin is superior to clopidogrel-aspirin for minor stroke or TIA patients who are CYP2C19 LOF allele carriers.Yongjun Wang Claiborne Johnston Philip M Bath Xia Meng Jing Jing Xuewei Xie Anxin Wang Yuesong Pan Anding Xu Qiang Dong Yilong Wang Xingquan Zhao Zixiao Li Hao Li 2021Stroke & Vascular Neurology2021,6,2:10
17Further studies on the numerical simulation of bubble plumes in the cold seepage active region显示文摘Using the occurrence characteristics of bubble plumes in the South China Sea as a reference, this paper continues to study the seismic responses produced by bubble plumes in the cold seepage active region. To make the plume modelling scheme more reasonable, we modified the original modelling scheme and reconstructed a plume water body model based on the variation of its radius as bubbles rise in seawater. The plume seismic records of shot gathers were obtained by forward simulation. The seismic records of single shot show obvious characteristics of a scattering wave field and the periodic characteristics of the model. Seismic records of shot gathers were processed using prestack depth migration. The boundary of its imaging section has a good convergence effect.The migration sections can be imaged distinctly with higher accuracy. The aforementioned studies once again laid a foundation for the further study of the seismic responses produced by plumes. They also gradually probed a more suitable seismic data processing method for plumes and provided a theoretical guidance for the identification of plumes.LI Canping GOU Limin YOU Jiachun LIU Xuewei OU Chuling 2016Acta Oceanologica Sinica2016,35,1:8
18Multi-scale simulation of single crystal hollow turbine blade manufactured by liquid metal cooling process显示文摘Liquid metal cooling(LMC) process as a powerful directional solidification(DS) technique is prospectively used to manufacture single crystal(SC) turbine blades. An understanding of the temperature distribution and microstructure evolution in LMC process is required in order to improve the properties of the blades. For this reason, a multi-scale model coupling with the temperature field, grain growth and solute diffusion was established. The temperature distribution and mushy zone evolution of the hollow blade was simulated and discussed.According to the simulation results, the mushy zone might be convex and ahead of the ceramic beads at a lower withdrawal rate, while it will be concave and laggard at a higher withdrawal rate, and a uniform and horizontal mushy zone will be formed at a medium withdrawal rate. Grain growth of the blade at different withdrawal rates was also investigated. Single crystal structures were all selected out at three different withdrawal rates.Moreover, mis-orientation of the grains at 8 mm/min reached ~30°, while it was ~5° and ~15° at 10 mm/min and 12 mm/min, respectively. The model for predicting dendritic morphology was verified by corresponding experiment. Large scale for 2D dendritic distribution in the whole sections was investigated by experiment and simulation, and they presented a well agreement with each other.Xuewei Yan Hang Zhang Ning Tang Changbo Sun Qingyan Xu Baicheng Liu 2018Progress in Natural Science:Materials International2018,28,1:8
19Prognostic significance of lymphovascular infiltration in overall survival of gastric cancer patients after surgery with curative intent显示文摘Objective: Lymphovascular infiltration(LVI) is frequently detected in gastric cancer(GC) specimens. Studies have revealed that GC patients with LVI have a poorer prognosis than those without LVI.Methods: In total, 1,007 patients with curatively resected GC at Department of Gastric Cancer, Tianjin Medical University Cancer Institute and Hospital were retrospectively enrolled. The patients were categorized into two groups based on the LVI status: a positive group(PG;presence of LVI) and a negative group(NG;absence of LVI). The clinicopathological factors corrected with LVI and prognostic variables were analyzed. Additionally, a pathological lymphovascular-node(lvN) classification system was proposed to evaluate the superiority of its prognostic prediction of GC patients compared with that of the eighth edition of the N staging system.Results: Two hundred twenty-four patients(22.2%) had LVI. The depth of invasion and lymph node metastasis were independently associated with the presence of LVI. GC patients with LVI demonstrated a significantly lower overall survival(OS) rate than those without LVI(42.8% vs. 68.9%, respectively;P<0.001). In multivariate analysis,LVI was identified as an independent prognostic factor for GC patients(hazard ratio: 1.370;95% confidence interval: 1.094-1.717;P=0.006). Using strata analysis, significant prognostic differences between the groups were only observed in patients at stage I-IIIa or N0-2. The lvN classification was found to be more appropriate to predict the OS of GC patients after curative surgery than the pN staging system. The-2 log-likelihood of lvN classification(4,746.922) was smaller than the value of pN(4,765.196), and the difference was statistically significant(χ^2=18.434, P<0.001).Conclusions: The presence of LVI influences the OS of GC patients at stage Ⅰ-Ⅲ a or N0-2. LVI should be incorporated into the pN staging system to enhance the accuracy of the prognostic prediction of GC patients.Liangliang Wu Yuexiang Liang Chen Zhang Xiaona Wang Xuewei Ding Chongbiao Huang Han Liang 2019Chinese Journal of Cancer Research2019,31,5:8
20Identification and characterization of rice blast resistance gene Pid4 by a combination of transcriptomic profiling and genome analysis显示文摘Map-based cloning of plant disease resistance (R) genes is time-consuming. Here, we reported the isolation of blast R gene Pid4 using comparative transcriptomic profiling and genome-wide sequence analysis. Pid4 encodes a coiled-coil nucleotide-binding site leucine-rich repeat(CC-NBS-LRR) protein and is constitutively expressed at diverse developmental stages in the rice variety Digu. The Pid4 protein is localized in both the nucleus and cytoplasm. Introduction of Pid4 into susceptible rice cultivars confers race-specific resistance to leaf and neck blast. Amino acid sequence comparison and blast resistance spectrum tests showed that Pid4 is a novel R gene, different from the previously reported R genes located in the same gene cluster. A Pid4 Indel marker was developed to facilitate the identification of Pid4 in different rice varieties. We demonstrated that a plant R gene can be quickly isolated using transcriptomic profiling coupled with genome-wide sequence analysis.Zhixiong Chen Wen Zhao Xiaobo Zhu Chengdong Zou Junjie Yin Mawsheng Chern Xiaogang Zhou Heng Ying Xin Jiang Yongzhen Li Haicheng Liao Mengping Cheng Weitao Li Min He Jing Wang Jichun Wang Bingtian Ma Jirui Wang Shigui Li Lihuang Zhu Xuewei Chen 2018Journal of Genetics and Genomics2018,45,12:7
