| 2 | Prognostic factors of refractory NSCLC patients receiving anlotinib hydrochloride as the third-or further-line treatment显示文摘Objective:Anlotinib hydrochloride is a multitarget tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor,fibroblast growth factor receptor,platelet-derived growth factor receptor,c-Kit,and c-MET;therefore,it exhibits both antitumor and anti-angiogenetic activities.A phase III trial has shown that anlotinib improved progression-free survival(PFS)and overall survival(OS)in patients with advanced non-small cell lung cancer(NSCLC),who presented with progressive disease or intolerance after standard chemotherapy.This study aimed to analyze the characteristics of patients receiving anlotinib treatment to determine the dominant populations who are fit for the treatment.Methods:Data were collected from March 2015 to January 2017 from a randomized,double-blind,placebo-controlled,multicenter,phase III trial of anlotinib(ALTER0303).A total of 437 patients were enrolled and randomly allocated(2:1)to the anlotinib and placebo groups.Kaplan–Meier analysis and log-rank test were performed to compare PFS and OS.Cox proportional hazards model was adopted for multivariate prognostic analysis.Results:Multivariate analysis indicated that high post-therapeutic peripheral blood granulocyte/lymphocyte ratio and elevated alkaline phosphatase levels were independent risk factors for PFS.Meanwhile,elevated thyroid-stimulating hormone,blood glucose,and triglyceride levels;hypertension;and hand–foot syndrome were independent protective factors of PFS.High posttherapeutic peripheral blood granulocyte/lymphocyte ratio,an Eastern Cooperative Oncology Group(ECOG)score≥2,and the sum of the maximal target lesion length at baseline were independent risk factors of OS,and hypertriglyceridemia was an independent protective factor of OS.Conclusions:This study preliminarily explored the possible factors that affected PFS and OS after anlotinib treatment in patients with advanced refractory NSCLC,and the baseline characteristics of the therapeutically dominant populations were then identified. | Jing Wang Yizhuo Zhao Qiming Wang Li Zhang Jianhua Shi Zhehai Wang Ying Cheng Jianxing He Yuankai Shi Hao Yu Yang Zhao Weiqiang Chen Yi Luo Xiuwen Wang Kejun Nan Faguang Jin Jian Dong Baolan Li Zhujun Liu Baohui Han Kai Li | 2018 | Cancer Biology & Medicine2018，15，4： | 46 |

| 4 | Bow-tie topological features of metabolic networks and the functional significance显示文摘Exploring the structural topology of genome-based large-scale metabolic network is essential for in- vestigating possible relations between structure and functionality.Visualization would be helpful for obtaining immediate information about structural organization.In this work,metabolic networks of 75 organisms were investigated from a topological point of view.A spread bow-tie model was proposed to give a clear visualization of the bow-tie structure for metabolic networks.The revealed topological pattern helps to design more efficient algorithm specifically for metabolic networks.This coarse- grained graph also visualizes the vulnerable connections in the network,and thus could have important implication for disease studies and drug target identifications.In addition,analysis on the reciprocal links and main cores in the GSC part of bow-tie also reveals that the bow-tie structure of metabolic networks has its own intrinsic and significant features which are significantly different from those of random networks. | ZHAO Jing TAO Lin YU Hong LUO JianHua CAO ZhiWei LI YiXue | 2007 | Chinese Science Bulletin2007，52，8： | 19 |
| 5 | Effect of temperature on corrosion behavior of 3003 aluminum alloy in ethylene glycol–water solution显示文摘The effect of temperature on the corrosion behavior of 3003 aluminum alloy in ethylene glycol–water solution was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy(EIS) techniques. The surface characterization was observed and determined by scanning electron microscopy(SEM), atomic force microscopy(AFM) and energy dispersive spectrometer(EDS). The results demonstrate that the anodic aluminum dissolution and the cathodic oxygen reduction were accelerated by the increased temperature. However, as temperature was over60 °C, the solubility and concentration of oxygen decreased, resulting in the inhibition of cathodic reaction. The cathodic reaction rate of 3003 aluminum alloy rose to the maximum at 60 °C. The Warburg impedance in Nyquist diagram diminished and then was replaced by a negative capacitance caused by the absorption of intermediate corrosion product on electrode. On the other hand,after potentiodynamic measurements, 3003 aluminum alloy suffered pitting corrosion. The dissolution of aluminum alloy around secondary phase particles expanded both horizontally and vertically. | Chen Xin Tian Wenming Li Songmei Yu Mei Liu Jianhua | 2016 | Chinese Journal of Aeronautics2016，29，4： | 14 |
| 6 | Patterns,magnitude,and controlling factors of hydraulic redistribution of soil water by Tamarix ramosissima roots显示文摘Tamarix spp.(Saltcedar)is a facultative phreatophyte that can tolerate drought when groundwater is not accessed.In addition to deep water uptake,hydraulic redistribution(HR)is another factor contributing to the drought tolerance of Tamarix spp.In this study,data on soil volumetric moisture content(θ),lateral root sap flow,and relevant climate variables were used to investigate the patterns,magnitude,and controlling factors of HR of soil water by roots of Tamarix ramosissima Ledeb.in an extremely arid land in Northwest China.Results showed evident diurnal fluctuations in θ at the depths of 30 and 50 cm,indicating 'hydraulic lift'(HL).θ increased remarkably at 10 and 140 cm but decreased at 30 and 50 cm and slightly changed at 80 cm after rainfall,suggesting a possible 'hydraulic descent'(HD).However,no direct evidence was observed in the negative flow of lateral roots,supporting HR(including HL and HD)of T.ramosissima.The HR pathway unlikely occurred via lateral roots;instead,HR possibly occurred through adventitious roots with a diameter of 2-5 mm and a length of 60-100 cm.HR at depths of 20-60 cm ranged from 0.01-1.77 mm/d with an average of 0.43 mm/d,which accounted for an average of 22% of the estimated seasonal total water depletion at 0-160 cm during the growing season.The climate factors,particularly vapor pressure deficit and soil water potential gradient,accounted for at least 33% and 45% of HR variations with depths and years,respectively.In summary,T.ramosissima can be added to the wide list of existing species involved in HR.High levels of HR may represent a considerable fraction of daily soil water depletion and substantially improve plant water status.HR could vary tremendously in terms of years and depths,and this variation could be attributed to climate factors and soil water potential gradient. | TengFei YU Qi FENG JianHua SI HaiYang XI Wei LI | 2013 | Journal of Arid Land2013，5，3： | 12 |
| 7 | Experiment in metal disturbance during advanced detection using a transient electromagnetic method in coal mines显示文摘Tunneling machines, or excavators, are large and good conductors and affect the reliability of data gathering and inter-pretation in advanced detection using transient electromagnetic methods. In our experiment, we used a coincident-loop and central loop type of configuration, where the coil plane 1) vertical to and 2) parallel to the working face. A SIROTEM instrument at differ-ent locations was used to observe the transient electromagnetic responses of the excavator and to analyze the response amplitudes. The result shows that the tunneling machine affects the advanced detection data and is related to the way the coil is coupled. When the excavator is 6 m from the observatory, the interference of tunneling machine can be ignored. | JIANG Zhihai YUE Jianhua YU Jingcun | 2010 | Mining Science and Technology2010，20，6： | 12 |

| 10 | Numerical simulations of land surface physical processes and land-atmosphere interactions over oasis-desert/Gobi region显示文摘A land-surface physical process model was coupled with a mesoscale atmospheric model. This cou- pled model was then used to simulate the interactions between land and the atmosphere, including surface temperature, net radiation, sensible heat flux and latent heat flux over a desert/Gobi with an oasis in northwestern semiarid regions in China. Comparisons between observations and simulations were made over the oasis and the desert/Gobi, respectively. Both cold island effect and wet island ef- fect, the so-called oasis effect, were observed and simulated. Lower temperature, higher specific hu- midity and weaker turbulent transfer were present over the oasis than the desert/Gobi. A subsidence occurred over the oasis, leading to a thermally-generated mesoscale circulation. | LIU ShuHua LIU HePing HU Yu ZHANG ChengYi LIANG FuMing WANG JianHua | 2007 | Science China Earth Sciences2007，50，2： | 9 |

| 12 | Response of Populus euphratica Oliv.sap flow to environmental variables for a desert riparian forest in the Heihe River Basin,Northwest China显示文摘Being an important desert riparian forest in the lower reaches of the Heihe River Basin,Populus euphratica Oliv.forest functions as a natural barrier in maintaining and preserving the stability of local oases.Accordingly,accurately estimating the water use of P.euphratica is important for vegetation protection and water resource allocation.To date,little data are available for evaluating the hysteretic effects between sap flow and environmental variables,and for estimating the water use of desert riparian forest.In this study,we measured the sap flow velocity(V_s)of P.euphratica using the heat ratio method during the growing season of 2012.Based on the response of V_s to solar radiation(R_s)and vapor pressure deficit(VPD),we estimated the hourly Vsand daily V_s using the multivariable linear regression and a modified Jarvis-Stewart(JS)model,respectively.Hysteretic response of V_s to environmental variables was then evaluated using a sap flow model.We found the thresholds of V_s responses to R_s and VPD at both hourly and daily scales during the growing season,and successfully estimated the seasonal variations of hourly V_s and daily V_s using the JS model.At an hourly scale,the maximum V_s occurred earlier than the maximum VPD by approximately 0.5 h but later than the maximum R_s by approximate 1.0 h.At a daily scale,the maximum V_s lagged behind the maximum VPD by approximately 2.5 h while occurred earlier than the maximum R_s by approximately 2 h.However,hysteretic response of V_swas weakened when R_s and VPD were measured together using the JS model at both hourly and daily scales.Consequently,short-term and intensive field campaigns,where V_s and environmental variables can be measured,may be used to estimate short-run sap flow and stand transpiration using only two environmental variables. | LI Wei SI Jianhua YU Tengfei LI Xiaoyan | 2016 | Journal of Arid Land2016，8，4： | 9 |
| 13 | Weekly albumin-bound paclitaxel/cisplatin versus gemcitabine/cisplatin as first-line therapy for patients with advanced non-small-cell lung cancer:A phase II open-label clinical study显示文摘Objective: The aim of this trial was to compare both the efficacy and the safety of a weekly nanoparticle albumin-bound paclitaxel(nab-paclitaxel) plus cisplatin vs. gemcitabine plus cisplatin in patients with advanced non-small-cell lung cancer(NSCLC).Methods: A total of 84 participants received either 100 mg/m^2 nab-paclitaxel each week on d 1, 8 and 15 of a 28 day cycle, as well as cisplatin 75 mg/m^2 on d 1 every three weeks(nab-TP arm); or gemcitabine 1,000 mg/m^2 on d 1 and 8, plus cisplatin 75 mg/m^2 on d 1 every three weeks(GP arm). The primary end point was progression-free survival(PFS). The secondary end points were overall response rate(ORR) and overall survival(OS).Results: According to our analysis, the median PFS was 4.8 months for the nab-TP arm vs. 5.2 months for the GP arm(P=0.55). Analysis showed the median OS was 14.6 months for participants who were in the nab-TP arm vs. 15.1 months for those in the GP arm(P=0.94). Besides, nab-TP showed OS advantages over GP in patients harboring epidermal growth factor receptor(EGFR) mutation(26.7 vs. 15.3 months, P=0.046) and patients with a performance status of 0(23.5 vs. 14.7 months, P=0.020). It was found that incidences of drug-related grade 3 or 4 toxicities were comparable between the two treatment arms.Conclusions: Therefore, it can be seen that weekly nab-TP treatment has a similar efficacy and tolerability to GP treatment for patients who are undergoing their first-line treatment for NSCLC. It could be that survival differences among platinum doublets in the context of both EGFR mutation and performance status have the potential to be the basis for our further clinical trials. | Shanshan Qin Hui Yu Xianghua Wu Zhiguo Luo Huijie Wang Si Sun Mingzhu Huang Jia Jin Zhonghua Tao Jie Qiao Yu Feng Jialei Wang Jianhua Chang | 2019 | Chinese Journal of Cancer Research2019，31，2： | 9 |
| 14 | Embedded reservoir and constructed wetland for drinking water source protection:Effects on nutrient removal and phytoplankton succession显示文摘An embedded reservoir that provides an efficient nutrient removal system protects drinking water.However,embedded reservoirs are rarely used in eutrophic shallow lakes because of their undetermined nutrient retention efficiency and unknown effects by the phytoplankton community.In this study,we aim to investigate the nutrient retention and algae succession in an embedded reservoir and adjacent wetland from April 2017 to September 2018 in the eastern part of Lake Taihu,China.More than 40%of total phosphorus(TP)and 45%of particulate phosphorous entering the reservoir were retained semiannually,and the highest TP removal efficiency was achieved in the reservoir during autumn with an average value of 53.3%±9.9%.The overall nitrogen retention efficiency(21.7%±37.8%)was lower than that of TP(41.8%±27.8%).Similar trends were obtained in the wetland area.An important pathway for phosphorus removal is through particulate matter retention.Our study revealed that nutrient retention mechanisms in the reservoir were primarily via macrophyte absorption,particulate substance sedimentation,and prolonged water residence time.Consequently,the phytoplankton biomass(Chl-a)in the reservoir decreased(from 48.0 to 25.2μg/L)and water transparency improved,due to the decreased P level and transformation of the phytoplankton group into simple structures with good ecological status.Therefore,the combination of embedded reservoir and constructed wetland ecosystem can be used successfully to protect surface water.The results will be advantageous to groups seeking to preserve drinking water sources. | Changtao Yang Jing Nan Huaiyong Yu Jianhua Li | 2020 | Journal of Environmental Sciences2020，32，1： | 9 |
| 15 | Failure modes of coal containing gas and mechanism of gas outbursts显示文摘In order to explain the mechanism for gas outburst, the process of evolving fractures in coal seams is described using system dynamics with variable boundaries. We discuss the failure modes of coal containing gas and then established the flow rules after failure. The condition under which states of deformation convert is presented and the manner in which these convert is proposed. In the end, the process of gas outbursts is explained in detail. It shows that a gas outburst is a process in which the boundaries of coal seams are variable because of coal failure. If the fractures are not connected or even closed owing to coal/rock stress, fractured zones will retain a certain level of carrying capacity because of the self-sealing gas pressure. When the accumulation of gas energy reaches its limit, coal seams will become unstable and gas outbursts take place. | HUANG Wei CHEN Zhanqing YUE Jianhua ZHANG Yu YANG Min | 2010 | Mining Science and Technology2010，20，4： | 9 |
| 16 | Trends of Overweight and Obesity in Yi People between 1996 and 2007:An Yi Migrant Study显示文摘Objective To evaluate trends of overweight and obesity prevalence between 1996 and 2007 in Yi farmers and Yi migrants.Methods An Yi migrant study was conducted in Liangshan Yi Autonomous Prefecture,Sichuan Province,China from 1996 to 2007.Data were collected with identical methods,including standardized questionnaire and body measurements.Results Age‐ and sex‐specific body mass index (BMI) significantly increased from 20.02 in 1996 to 22.36 in 2007,among Yi farmers,which was significantly different from those among Yi migrants (23.67 in 2007 and 20.90 in 1996) (P<0.05).Prevalence of obesity rose from 1.21 % in 1996 to 4.55 % in 2007 (OR=1.15,P<0.001) in Yi migrants,while that in Yi farmers from none in 1996 to 0.12 % in 2007 (P>0.05).Prevalence of overweight rose significantly to 26.24 %in 2007 from 17.24 % in 1996 (OR=1.06,P<0.001) in Yi migrants,while that in Yi farmers from 1.29 % in 1996 to 4.45 % in 2007 (OR=1.14,P<0.001).Yi migrants appeared to have a 5.52‐fold higher risk ondeveloping overweight and obesity than Yi farmers have.Conclusion The Yi migrants had a steeper increase of overweight with year and consequently caused more obesity.Change in lifestyle may contribute most likely to higher prevalence of overweight and obesity in Yi migrants. | SHAN GuangLiang WEI DaYing WANG ChunXiu ZHANG JianHua Wang Bin MA MingJu PAN Li YU Tao XUE Fang WU ZhengLai | 2011 | Biomedical and Environmental Sciences2011，24，5： | 9 |
| 17 | Modeling micro-particle deposition in human upper respiratory tract under steady inhalation显示文摘A representative human upper respiratory tract (URT) with idealized oral region and asymmetric tracheo-bronchial (TB) airway has been modeled, and laminar-to-turbulent airflow for typical inhalation modes as well as micro-particle transport and deposition has been simulated using CFX10.0 software from Ansys Inc. on a personal computer. The asymmetric TB airway could not be replaced by an extended straight tube as outlet of the oral region while investigating the tracheal airflow field and particle deposition. Compared to an idealized oral airway with an extended straight tube, several differences could be noted: (i) The laryngeal jet extends further down the trachea and inclines towards the anterior wall; (ii) the turbulence level in trachea is less and decays more quickly; (iii) three recirculation zones are visible with intense adverse current after the glottis; (iv) deposition of small particles in trachea is reduced due to lower turbulence. Refined unstructured mesh with densified boundary layer mesh could be a proper substitute for the structured mesh in the human URT model with asymmetric TB airway. Based on the refined unstructured mesh, the physiological structure of uvula in the soft palate is properly simulated in the present human URT model. | Jianhua Huang Lianzhong Zhang Suyuan Yu | 2011 | Particuology2011，9，1： | 9 |
| 18 | Effect of air bubble size on cavitation erosion reduction显示文摘Over the past 60 years, the air concentration in water has been considered as a control index of cavitation erosion reduction and widely used in the designs of hydraulic structures. However, the mechanism of air entrainment against cavitation erosion has been paid good attention to. In the present work, the effect of air bubble size on cavitation erosion reduction was experimentally investigated. A device with micron-scale orifice diameters(10, 20 and 50 μm in size) was specially designed to introduce air bubbles into water. The experiments about the effect of air bubble size were conducted by means of a vibratory apparatus, including the behavior of formation and movement for single air bubble, the characteristics of cavitation erosion reduction at different air entrainment conditions. The findings demonstrate that high air concentration has significant effects on cavitation erosion reduction.But, a notable problem was that the size of air bubbles is of outstanding effect on cavitation erosion reduction. Small air bubbles support to alleviate cavitation erosion, even at same air concentration. | WU JianHua SU KunPeng WANG Yu GOU WenJuan | 2017 | Science China(Technological Sciences)2017，60，4： | 8 |
| 19 | Sintilimab versus docetaxel as second-line treatment in advanced or metastatic squamous non-small-cell lung cancer:an open-label,randomized controlled phase 3 trial(ORIENT-3)显示文摘Background:Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer(sqNSCLC)after failure of first-line chemotherapy are limited.This study(ORIENT-3)aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC.Methods:ORIENT-3 was an open-label,multicenter,randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy.Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m^(2) of docetaxel intravenously every 3 weeks,stratified by the Eastern Cooperative Oncology Group performance status.The primary endpoint was overall survival(OS)in the full analysis set(FAS).Secondary endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),duration of response(DoR)and safety.Results:Between August 25,2017,and November 7,2018,290 patients were randomized.For FAS,10 patients fromthe docetaxel armwere excluded.Themedian OS was 11.79(n=145;95%confidence interval[CI],10.28-15.57)months with sintilimab versus 8.25(n=135;95%CI,6.47-9.82)months with docetaxel(hazard ratio[HR]:0.74;95%CI,0.56-0.96;P=0.025).Sintilimab treatment significantly prolonged PFS(median 4.30 vs.2.79 months;HR:0.52;95%CI,0.39-0.68;P<0.001)and showed higher ORR(25.50%vs.2.20%,P<0.001)and DCR(65.50%vs.37.80%,P<0.001)than the docetaxel arm.The median DoRwas 12.45(95%CI,4.86-25.33)months in the sintilimab arm and 4.14(95%CI,1.41-7.23)months in the docetaxel arm(P=0.045).Treatment-related adverse events of grade≥3were reported in 26(18.1%)patients in the sintilimab arm and 47(36.2%)patients in the docetaxel arm.Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors,including OVOL2(HR:0.35;P<0.001)and CTCF(HR:3.50;P<0.001),for sintilimab treatment.Conclusions:Compared with docetaxel,sintilimab significantly improved the OS,PFS,and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC. | Yuankai Shi Lin Wu Xinmin Yu Puyuan Xing Yan Wang Jianying Zhou Airong Wang Jianhua Shi Yi Hu Ziping Wang Guangyu An Yong Fang Sanyuan Sun Caicun Zhou Changli Wang Feng Ye Xingya Li Junye Wang Mengzhao Wang Yunpeng Liu Yanqiu Zhao Ying Yuan Jifeng Feng Zhendong Chen Jindong Shi Tao Sun Gang Wu Yongqian Shu Qisen Guo Yi Zhang Yong Song Shucai Zhang Yuan Chen Wei Li Hongrui Niu Wenwei Hu Lijun Wang Jianan Huang Yang Zhang Ying Cheng Zhengdong Wu Bo Peng Jiya Sun Christoph Mancao Yanqi Wang Luyao Sun | 2022 | Cancer Communications2022，42，12： | 8 |
| 20 | Land-Use Spatial Optimization Based on PSO Algorithm显示文摘The optimization of land-use spatio-structure is one of the most important areas of land use management;constructing a spatial optimization model that is based on the micro spatial unit in a bottom-up mode plays an important role in coupling the quan-tity structure and spatial structure effectively.The objective of this research is to develop a land use spatial optimization model based on particle swarm optimization to make spatial decision in land use management.The model is implemented using real data-sets to emulate the process of spatial structure optimization in order to get the best landscape pattern under the control of decision environments.Simulation results revealed that the particle swarm optimization model has the ability to utilize the quantity and spa-tial structure.Furthermore,the result demonstrated that it can be used to stimulate the landscape pattern in designing the appropriate optimization environment,which could land quantity target to the basic spatial units effectively and provide appropriate spa-tio-structure for regional land use space layout decision making. | MA Shifa HE Jianhua LIU Feng YU Yan | 2011 | Geo-Spatial Information Science2011，14，1： | 8 |
