| 1 | Curative effect of Dingqi analgesic patch on cancer pain:a single-blind randomized controlled trail显示文摘OBJECTIVE:To observe the curative effect of an acupoint application with a Dingqi analgesic patch on moderate to severe pain caused by liver cancer.METHODS:Forty patients with moderate to severe pain caused by liver cancer were randomly divided intoatreatmentgroup(TG)andacontrolgroup(CG).Patients with moderate pain were given 100 mg qd of a sustainably released tablet of tramadol hydrochloride;patientswithseverepainweregiven4.2mg q3d of the fentanyl transdermal system.The ashi points Ganshu(BL 18),Danshu(BL 19) and Qimen(LR 14) were chosen for the acupoint application intervention.CG patients were given a sham patch and TG patients were given a Dingqi analgesic patch.A visual analogue scale(VAS) was used before treatment and after 1,3,6,9 and 12 days of treatment.The Karnofsky score was measured before treatment and after 12 days of treatment.Any main adverse reactions(e.g.nausea,constipation,dizziness and headache) were recorded after 6 and 12 days of treatment.Any skin side effects(i.e.skin irritation and allergic reactions) were recorded.RESULTS:The VAS in TG was significantly lower than that in CG after 3,6,9 and 12 days of treatment(P<0.05).There was no significant difference in the Karnofsky score before treatment and after 12 days of treatment between CG and TG.There were also no significant differences in the main adverse reactions or skin side effects after 6 and 12 days of treatment between CG andTG(P>0.05).CONCLUSION:The Dingqi analgesic patch can enhance the analgesic effect of tramadol and fentanyl. | Changjun Wang Wei Tan Xuhui Huang Tingting Fu Juze Lin Junmin Bu Guojian Wei Yu Du | 2013 | Journal of Traditional Chinese Medicine2013，33，2： | 9 |
| 2 | Field measurements of settling velocities of fine sediments in Three Gorges Reservoir using ADV显示文摘The Three Gorges Reservoir(TGR) is suffering from unexpected fine sediment deposition,to better understand the fine sediment transport processes,field measurements were conducted at the Zhongxian and Fengjie reaches.A method based on the sediment diffusion equation was proposed to measure the settling velocities using the Acoustic Doppler Velocimeter(ADV).The backscatter acoustic intensities(BSI) received from the ADV were calibrated against the sediment concentrations measured via water sampling,suggesting a linear relationship in double logarithmic coordinate system.The instantaneous sediment concentration was calculated using the derived relationship,and then the settling velocity was obtained through the proposed procedure.The settling velocities of the fine particles in the TGR were found to vary with the water depth.Most of the effective settling velocities were within the range of 0.1-10 mm/s,which were larger than those of the primary particles,indicating that the flocculation was likely to occur in the TGR.Additionally,it is suggested that the turbulent motion played an important role in the flocculation in the TGR. | Wenjie Li Shengfa Yang Jiang Hu Xuhui Fu Peng Zhang | 2016 | International Journal of Sediment Research2016，31，3： | 6 |
| 3 | Experimental investigation on propagating characteristics of sinusoidal unsteady flow in open-channel with smooth bed显示文摘A high accuracy experimental system has been established for unsteady open-channel flow.Then 40 experiments were conducted to study the propagating characteristics of unsteady open-channel flow.From the experimental data,the variation law of propagating velocity,wave deformation rate,flow depth of wave peak and bottom,and other parameters were obtained.The experimental results show the followings.1) The propagating velocity of unsteady open-channel flows can be expressed by the sum of flow velocity and micro-amplitude wave velocity at wave peak.2) The waveform of an unsteady flow would deform when it propagates,with the rising stage becoming longer and the falling stage shorter;the deformation rate is a function of distance,period and relative amplitude of discharge.3) The flow depths of wave peak and bottom have a close relationship with the period of the unsteady flow.When the period is short,water depths of wave peak and bottom are both close to those of the average discharge in the condition of uniform flow.For a long period unsteady flow,the water depth of wave peak is close to that of the maximal discharge in the condition of uniform flow,while at the flow wave bottom,it is close to the depth of the minimum discharge in an uniform flow.4) Propagating characteristic of discharge is analogous to that of flow depth for unsteady flow. | HU Jiang YANG ShengFa FU XuHui | 2012 | Science China(Technological Sciences)2012，55，7： | 4 |
| 4 | QTL analysis across multiple environments reveals promising chromosome regions associated with yield-related traits in maize under drought conditions显示文摘Drought is one of the most critical abiotic stresses influencing maize yield. Improving maize cultivars with drought tolerance using marker-assisted selection requires a better understanding of its genetic basis. In this study, a doubled haploid(DH) population consisting of 217 lines was created by crossing the inbred lines Han 21(drought-tolerant) and Ye 478(drought-sensitive). The population was genotyped with a 6 K SNP assay and 756 SNP(single nucleotide polymorphism) markers were used to construct a linkage map with a length of 1344 c M. Grain yield(GY), ear setting percentage(ESP), and anthesis–silking interval(ASI) were recorded in seven environments under well-watered(WW) and water-stressed(WS) regimes. High phenotypic variation was observed for all traits under both water regimes. Using the LSMEAN(least-squares mean) values from all environments for each trait, 18 QTL were detected, with 9 associated with the WW and 9 with the WS regime. Four chromosome regions,Chr. 3: 219.8–223.7 Mb, Chr. 5: 191.5–194.7 Mb, Chr. 7: 132.2–135.6 Mb, and Chr. 10: 88.2–89.4 Mb, harbored at least 2 QTL in each region, and QTL co-located in a region inherited favorable alleles from the same parent. A set of 64 drought-tolerant BC_3F_6 lines showed preferential accumulation of the favorable alleles in these four regions, supporting an association between the four regions and maize drought tolerance. QTL-by-environment interaction analysis revealed 28 ed QTL(environment-dependent QTL) associated with the WS regime and 22 associated with the WW regime for GY, ESP, and ASI. All WS QTL and55.6% of WW QTL were located in the ed QTL regions. The hotspot genomic regions identified in this work will support further fine mapping and marker-assisted breeding of drought-tolerant maize. | Xinmin Hu Guihua Wang Xuemei Du Hongwei Zhang Zhenxiang Xu Jie Wang Guo Chen Bo Wang Xuhui Li Xunji Chen Junjie Fu Jun Zheng Jianhua Wang Riliang Gu Guoying Wang | 2021 | The Crop Journal2021，9，4： | 3 |
| 5 | Estimating instantaneous concentration of suspended sediment using acoustic backscatter from an ADV显示文摘The measurement of instantaneous sediment concentration remains a challenging task. In this study, a three-step procedure is proposed to estimate instantaneous sediment concentration using acoustic backscatter from Acoustic Doppler Velocimeter (ADV). The influences of acoustic noise and particle diameter on an ADV's performance was first tested in the laboratory, then the three-step procedure was verified based on field measurements in the Zhongxian and Fengjie reaches in the Three Gorges Reservoir. The first step involves reconstructing the backscatter signal time series. Due to contamination from both the noise floor and spurious spikes, the denoising-despiking method was applied instead of the traditional velocity-despiking methods, and this approach performed well based on spectrum ana-lysis. The second step involves calibrating the sediment concentration against the backscatter signal. A linear relation, whose slope and intercept were calibrated to be dependent on particle diameter, is proposed in double logarithmic coordinates. The third step involves calculating the instantaneous sediment concentration using reconstructed instantaneous backscatter based on the proposed relation. The accuracy of the proposed method was evaluated through consideration of the concentration spec-trum and sediment flux, indicating that the proposed three-step procedure is effective for the mea-surement of instantaneous sediment concentration. | Wenjie Li Shengfa Yang Wei Yang Yi Xiao Xuhui Fu Shuaishuai Zhang | 2019 | International Journal of Sediment Research2019，34，5： | 2 |

| 7 | A variational successive corrections approach for the sea ice concentration analysis显示文摘The sea ice concentration observation from satellite remote sensing includes the spatial multi-scale information.However,traditional data assimilation methods cannot better extract the valuable information due to the complicated variability of the sea ice concentration in the marginal ice zone.A successive corrections analysis using variational optimization method,called spatial multi-scale recursive filter(SMRF),has been designed in this paper to extract multi-scale information resolved by sea ice observations.It is a combination of successive correction methods(SCM)and minimization algorithms,in which various observational scales,from longer to shorter wavelengths,can be extracted successively.As a variational objective analysis scheme,it gains the advantage over the conventional approaches that analyze all scales resolved by observations at one time,and also,the specification of parameters is more convenient.Results of single-observation experiment demonstrate that the SMRF scheme possesses a good ability in propagating observational signals.Further,it shows a superior performance in extracting multi-scale information in a two-dimensional sea ice concentration(SIC)experiment with the real observations from Special Sensor Microwave/Imager SIC(SSMI). | Xuefeng Zhang Lu Yang Hongli Fu Dong Li Zheqi Shen Lianxin Zhang Xuhui Hu | 2020 | Acta Oceanologica Sinica2020，39，9： | 1 |

| 9 | International Meridian Circle Program显示文摘The Earth is buffered from the ferocious onslaught of the solar wind by a thin layer of matter known as the atmosphere and geospace.This layer absorbs energy from irradiance and outburst from the Sun,as well as from disasters,transient phenomena and anthropogenic emissions originated from Earth.Through complicated physics,the absorbed energy changes the atmospheric and geospace state and sometimes gets re-released to power extreme events such as space weather.Taking place globally,these complicated processes cannot be understood unless they are studied globally.The Chinese scientists have proposed the International Meridian Circle Program(IMCP)to meet this demand.By operating nearly 1000 instruments encompassing all latitudes along with the 120°E–60°W longitudes,IMCP aims,for the first time,to construct comprehensive 3D data representation of the atmosphere and geospace on a global scale and empower interdisciplinary research to tackle key questions related to Earth’s environment and climate change. | LIU William WANG Chi SHEN Xuhui WU Jian BLANC Michel YAN Yihua FU Suiyan YUE Xinan LEI Jiuhou GONG Wei ZHANG Shaodong ZHANG Qinghe WANG Xin YANG Jing ZHANG Xiaoxin GAO Jing XU Jiyao YANG Guotao LI Hui REN Liwen YANG Fang | 2020 | 空间科学学报2020，40，5： | 1 |
| 10 | Study on the optical system for the record of the pulsed acoustic field and the scattering of the cylindrical-like objects buried in underwater sand显示文摘The response of the two working mode of the optical systems, the schlieren mode and shadowgraph mode, for taking of optical photograph of the pulsed acoustic field in liquid are studied. It shows that, the response of the optical intensity on the screen to the acoustic pressure is linear for shadowgraph mode and nonlinear for the schlieren mode. Because the function of shadowgraph mode has no limit on working frequency, it is suitable for the studies of the acoustic field of laboratory model of the seabed or the buried objects at low ultrasonic range. The ultrasonic pulse scattered by the cylindrical-like objects buried in underwater sand was studied experimentally by the shadowgraph mode at low ultrasonic frequency. There are five kinds of the scattered waves from the half-buried object and three kinds of the waves from the full-buried objects were recorded. The two kinds of creeping waves (the longitudinal wave and the shear wave of the object) appear in both of the two cases. | ZHU Guozhen LU Ke’an YANG Xuhui FU Deyong(Department of Physics, Tsinghua University Beijing 100084) | 2002 | Chinese Journal of Acoustics2002，21，3： | 0 |
| 11 | The View of Micropropulsion Technology for China’s Advanced Small Platforms in Deep Space显示文摘In this paper,micropropulsion systems are analyzed in conjunction with the various mission requirements of China’s deep space exploration.As a great challenge facing the world,deep space exploration can be enabled only in a few countries with a success rate of around 50%.With the advancement of spacecraft and scientific instruments,it is now feasible to build small and low-cost spacecraft for a variety of deep space missions.As spacecraft become smaller,there is a need for proper micropropulsion systems.Examples of propulsion system selections for deep space exploration are discussed with a focus on products developed by Beijing Institute of Control Engineering(BICE).The requirements for propulsion systems are different in lunar/interplanetary exploration and gravitational wave detection.Chemical propulsion is selected for fast orbit transfer and electric propulsion for increasing scientific payloads.Cold gas propulsion and microelectric propulsion are good choices for space-based gravitational wave detection due to the capability of variable thrust output at the micro-Newton level.The paper also introduces the sub-1-U micropropulsion modules developed by BICE with satisfactory performance in flight tests,which are promising propulsion systems for small deep space platforms.A small probe with an electric sail propulsion system has been proposed for the future solar system boundary exploration of China.The electric sail serves as not only a propellant-free thruster but also a detector probing the properties of the space medium. | Yanming Wei Hao Yan Xuhui Liu Yang Yu Jinyue Geng Tao Chen Tuoqu Fu Gaoshi Su Yu Hu Daoman Han | 2022 | Space(Science & Technology)2022，，1： | 0 |
