| 1 | Preparation and coagulation efficiency of polyaluminium ferric silicate chloride composite coagulant from wastewater of high-purity graphite production显示文摘The aim of the present work was to produce a polyaluminium ferric silicate chloride (PAFSiC) coagulant from acidic and alkaline wastewater of purifying graphite by roasting, and subsequently to evaluate coagulation efficiency of the reagent by treating surface water from the Yellow River as well as municipal wastewater in comparison with the conventional coagulant polyaluminium chloride (PAC). The PAFSiC coagulant was prepared by co-polymerization. The effects of (Al+Fe)/Si molar ratio, OH/(Al+Fe) molar ratio (i.e., γ value), coagulant dosage and pH value of test suspension on the coagulation behavior of FAFSiC and the stability of the PAFSiC were also examined. Results showed that PAFSiC performed more efficiently than PAC in removing turbidity, chemical oxygen demand (COD), and total phosphate (TP). The PAFSiC with a γ value of 2.0 and (Al+Fe)/Si ratio of 5 (PAFSiC 2.0/5) showed excellent coagulation effect for both turbidity and COD, while PAFSiC 1.0/5 was the best for TP. The optimum coagulation pH range of PAFSiC 2.0/5 was 5.0–9.0, slightly wider than that of PAC (6.0–8.0). The process can be easily incorporated into high-purity graphite production plants, thereby reducing wastewater pollution and producing a valuable coagulant. | Xiaoxia Niu Xili Li Jihong Zhao Yigang Ren Yanqin Yang | 2011 | Journal of Environmental Sciences2011，23，7： | 23 |
| 2 | Effect of Bufei granule on stable chronic obstructive pulmonary disease: a randomized, double blinded, placebo-controlled, and multicenter clinical study显示文摘OBJECTIVE: To study the therapeutic effect Bufei granule, which is a traditional Chinese drug that can enhance the immune function of the lung, on patients with stable chronic obstructive pulmonary disease(COPD).METHODS: This is a randomized, double blinded,placebo-controlled, and multicenter clinical study.Three medical centers in Tianjin, China, participated in the trial. A total of 140 patients with stable COPD were enrolled and randomized into two groups, with 70 patients in each. The treatment group was treated with Bufei granule, while the control group received Bufei placebo. The pharmacological treatment lasted for 12 weeks from the date of enrollment. Then, the indexes of patients were observed. Data were analyzed to study the effect of Bufei granule, with the frequency of acute exacerbation as the primary outcome. Traditional Chinese Medicine syndromes,Modified British Medical Research Council dyspnea scale score, St.George's respiratory questionnaire scores, pulmonary function, and serum inflammatory marker levels [including interleukin-6(IL-6), interleukin-8, tumor necrosis factor-α, and transformation growth factor-β1]were the secondary outcomes.RESULTS: During the 12-week treatment, treatment and control groups had no adverse reactions.The analysis of the indexes obtained from all patients showed that the therapeutic effect in the treatment group was significantly better than that in the control group because most of the similar probabilities of primary and secondary outcomes were less than 0.05,except for the level of IL-6.CONCLUSION: Bufei granule can treat patients with stable COPD by lowering the frequency of acute exacerbation, improving the quality of life,and alleviating the severity of inflammation. | Sijia Guo Zengtao Sun Enshun Liu Jihong Feng Min Fu Yuechuan Li Qi Wu | 2014 | Journal of Traditional Chinese Medicine2014，34，4： | 19 |
| 3 | CPS Modeling of CNC Machine Tool Work Processes Using an Instruction-Domain Based Approach显示文摘Building cyber-physical system(CPS) models of machine tools is a key technology for intelligent manufacturing. The massive electronic data from a computer numerical control(CNC) system during the work processes of a CNC machine tool is the main source of the big data on which a CPS model is established. In this work-process model, a method based on instruction domain is applied to analyze the electronic big data, and a quantitative description of the numerical control(NC) processes is built according to the G code of the processes. Utilizing the instruction domain, a work-process CPS model is established on the basis of the accurate, real-time mapping of the manufacturing tasks, resources, and status of the CNC machine tool. Using such models, case studies are conducted on intelligent-machining applications, such as the optimization of NC processing parameters and the health assurance of CNC machine tools. | Jihong Chen Jianzhong Yang Huicheng Zhou Hua Xiang Zhihong Zhu Yesong Li Chen-Han Lee Guangda Xu | 2015 | Engineering2015，1，2： | 17 |

| 5 | DCAD:a Dual Clustering Algorithm for Distributed Spatial Databases显示文摘Spatial objects have two types of attributes: geometrical attributes and non-geometrical attributes, which belong to two different attribute domains (geometrical and non-geometrical domains). Although geometrically scattered in a geometrical domain, spatial objects may be similar to each other in a non-geometrical domain. Most existing clustering algorithms group spatial datasets into different compact regions in a geometrical domain without considering the aspect of a non-geometrical domain. However, many application scenarios require clustering results in which a cluster has not only high proximity in a geometrical domain, but also high similarity in a non-geometrical domain. This means constraints are imposed on the clustering goal from both geometrical and non-geometrical domains simultaneously. Such a clustering problem is called dual clustering. As distributed clustering applications become more and more popular, it is necessary to tackle the dual clustering problem in distributed databases. The DCAD algorithm is proposed to solve this problem. DCAD consists of two levels of clus- tering: local clustering and global clustering. First, clustering is conducted at each local site with a local clustering algorithm, and the features of local clusters are extracted. Second, local features from each site are sent to a central site where global clustering is obtained based on those features. Experiments on both artificial and real spatial datasets show that DCAD is effective and efficient. | ZHOU Jiaogen GUAN Jihong LI Pingxiang | 2007 | Geo-Spatial Information Science2007，10，2： | 14 |
| 6 | Multi-scale design and optimization for solid-lattice hybrid structures and their application to aerospace vehicle components显示文摘By integrating topology optimization and lattice-based optimization,a novel multi-scale design method is proposed to create solid-lattice hybrid structures and thus to improve the mechanical performance as well as reduce the structural weight.To achieve this purpose,a two-step procedure is developed to design and optimize the innovative structures.Initially,the classical topology optimization is utilized to find the optimal material layout and primary load carrying paths.Afterwards,the solid-lattice hybrid structures are reconstructed using the finite element mesh based modeling method.And lattice-based optimization is performed to obtain the optimal crosssection area of the lattice structures.Finally,two typical aerospace structures are optimized to demonstrate the effectiveness of the proposed optimization framework.The numerical results are quite encouraging since the solid-lattice hybrid structures obtained by the presented approach show remarkably improved performance when compared with traditional designs. | Chuang WANG Jihong ZHU Manqiao WU Jie HOU Han ZHOU Lu MENG Chenyang LI Weihong ZHANG | 2021 | Chinese Journal of Aeronautics2021，34，5： | 14 |
| 7 | Wideband electromagnetic characteristics modeling and analysis of missile targets in ballistic midcourse显示文摘The wideband electromagnetic characteristics of missile targets in midcourse are the foundation of midcourse attack-defense confrontation.This paper proposes a novel electromagnetic scattering modeling method for midcourse targets based on a precise scattering center model,in which the nonideal scattering phenomenon,shielding effect and micro-motion are taken into consideration for the first time.Firstly,a precise scattering center model incorporating both the sliding scattering and anisotropic scattering is established.Then the change rule of the target attitude is generalized,and a checking method of the scattering center shielding effect is proposed for rotationally symmetric targets.Afterwards,a novel dynamic electromagnetic scattering model is presented,where the scattering center model updates along with the variation of the target attitude and can characterize the change of the electromagnetic characteristics of midcourse targets exactly.Finally,in light of the established model,the dynamic electromagnetic characteristics within different attitude angle bounds are analyzed by stages,and some useful conclusions are obtained.Experiment results from the measured data in anechoic chamber verify the validity of the proposed modeling method and relevant analysis. | XU ShaoKun LIU JiHong WEI XiZhang LI Xiang GUO GuiRong | 2012 | Science China(Technological Sciences)2012，55，6： | 11 |
| 8 | Distribution, features, and influence factors of the submarine topographic boundaries of the Okinawa Trough显示文摘Based on multiple types of data, the topographical features of the Okinawa Trough(OT) have been characterized and a computation method has been proposed to determine the break point of continental shelf(BOS), foot point of the continental slope(FOS), the central axial point, and the maximum depth point. A total of 48 topographical profiles that crosscut the continental slope have been used to determine the trends of the BOS and FOS(the BOS and FOS lines) in the East China Sea(ECS). The trend of central axial points in the OT has been similarly determined by analyzing 39 topographical profiles across the axis of the trough. The BOS line forms the boundary between the continental shelf and slope. In the ECS, the BOS line roughly follows the 200 m isobath, continuously in the northern and middle parts of the OT, but jumping about somewhat in the south. The FOS line is the boundary between the continental slope and the bottom of the trough. The depth of the FOS increases gradually from north to south in the OT. Intense incisions by canyons into the slope in the southern part of the trough have led to the complex distribution of FOS. Topographical profiles crosscutting the northern, middle, and southern parts of the OT exhibit features that include: a single W-shape, a composite W-shape, and a U-shape, respectively, which suggests that in the middle and northern parts of the trough the central axial points are always located on seamount peaks or ridges associated with linear seamounts, whereas in the south they are found in the center of en echelon depressions. The line formed by the central axial points is the east-west dividing line of the OT, which indicates that the trough is a natural gap that prevents the extension of ECS continental shelf to the east. The distributions of the BOS and FOS lines are influenced by fluctuation of sea levels and submarine canyons, whereas the distribution of axis lines is controlled by tectonics and deposition. | WU ZiYin LI JiaBiao JIN XiangLong SHANG JiHong LI ShouJun JIN XiaoBing | 2014 | Science China Earth Sciences2014，57，8： | 11 |
| 9 | Distribution,formation and evolution of sand ridges on the East China Sea shelf显示文摘Based on the integrated results of multiple data types including MBES (Multi-Beam Echo Sounding) and historical topography maps,the LSR (Linear Sand Ridges) on the ECS (East China Sea) shelf are identified,divided into subareas,and classified.The distribution of sand ridge crests is also established.The strikes of the LSR on the ECS shelf fall in a normal distribution with the center point being 155° azimuth with additional peak points at 125°,130°,140°,and 180° azimuth.The distribution of the ECS shelf sand ridges is congested in the central area,sparse in the south and north ends,divergent and bifurcated in the eastern area,and densely convergent in the western area.The LSR are divided into seven subzones according to the strikes and distribution of the sand ridges;estuary mouth ridges and open shelf sand ridges are identified and marked out.The high amplitude change of sea level resulting from the glacial-interglacial cycle is the main cause of the vast development of sand ridges on the ECS shelf.Abundant sediments on the shelf carried by the PYR (Paleo-Yangtze River) are the material source for the LSR formation,and the negative seafloor topography influences the strikes of LSR.Based on the effects of LSR distribution,change of sea level,and the simulation of ancient tidal currents,the evolution of the LSR on the ECS shelf is divided into four main stages:Stage Ⅰ before 14.5 ka BP,Stage Ⅱ between 12 and 14 ka BP,Stage Ⅲ from 1.5 to 9.5 ka BP,and Stage Ⅳ after 9 ka BP. | WU ZiYin JIN XiangLong CAO ZhenYi LI JiaBiao ZHENG YuLong SHANG JiHong | 2010 | Science China Earth Sciences2010，53，1： | 9 |

| 11 | Risk-based security-constrained economic dispatch in power systems显示文摘Based on a new perspective in coordinating with the traditional'N-1'criteria and system risk,a real-time electricity market model is presented,in which the system risk is employed to model the system’s overall security level.This new model is called the risk-based security-constrained economic dispatch(RB-SCED).Relative to the securityconstrained economic dispatch(SCED)used in the power industry today,the RB-SCED finds more secure and economic operating conditions.It does this by obtaining solutions that achieve a better balance between post-contingency flows on individual branches and the overall system risk.The method exploits the fact that,in a SCED solution,some postcontingency branch flows which exceed their limits impose little risk while other post-contingency branch flows which are within their limits impose significant risk.The RB-SCED softens constraints for the former and hardens constraints for the latter,thus achieving simultaneous improvement in both security and economy.In this work,the basic concept and the mathematical formulation of the RB-SCED model are systematically described.Experimental results on a 9-bus system and the ISO New England actual system have demonstrated the advantages of RB-SCED over SCED. | Qin WANG Aimin YANG Fushuan WEN Jihong LI | 2013 | Journal of Modern Power Systems and Clean Energy2013，1，2： | 8 |
| 12 | Effect of Squeeze Casting on Microstructure and Mechanical Properties of Hypereutectic Al-xSi Alloys显示文摘The effect of squeeze casting on microstructure and mechanical properties of hypereutectic Al-xS i alloys(x = 15, 17.5, 22 wt%) was investigated in this study. Results show that microstructure of the hypereutectic Al-x Si alloys was obviously improved by squeeze casting. The amount of coarse primary Si phase decreased, while that of ?ne primary α-Al dendrites increased with the increase of squeeze casting pressure. Due to the decrease of coarse primary Si particles, cracking of the matrix was reduced, whilst the?ne microstructure, and mechanical properties of the squeeze casting alloys were improved. Compared with gravity casting alloys, mechanical properties of the hypereutectic Al-xS i alloys solidi?ed at 600 MPa were improved signi?cantly. Hardness of the squeeze casting hypereutectic Al-(15, 17.5, 22 wt%) Si alloys was improved by 15.91%, 12.23%, 17.48%, ultimate tensile strength was improved by 37.85%, 32.27%, 22.74%,and elongation was improved by 55.83%, 167.86%, 126.76%, respectively. Due to the uniform distribution of Si phases in squeeze casting Al-x Si alloys, their wear resistance was markedly enhanced. | Runxia Li Lanji Liu Lijun Zhang Jihong Sun Yuanji Shi Baoyi Yu | 2017 | Journal of Materials Science & Technology2017，33，4： | 8 |
| 13 | Effects of insoluble dietary fiber from wheat bran on noodle quality显示文摘Benefiting from its favorable effects in promoting intestinal peristalsis,increasing satiety and reducing postprandial blood sugar,wheat bran insoluble dietary fiber(IDF)could be added to noodles to improve the nutrition value of noodle products.However,the addition of IDF usually results in an adverse effect on the quality characteristics of fiber fortified products,leading to unfavorable texture and consumption drop.It was found that IDF could weaken dough characteristics,thereby causing the quality deterioration of noodles,but the mechanism is unclear as yet.This study aimed to investigate the effects of different amounts of IDF on the texture quality and cooking quality of noodles.The water distribution,rheological properties,pasting properties and cooking properties of the noodles were determined by low-field nuclear magnetic resonance(LF-NMR),dynamic rheometer,and rapid visco-analyzer.The results of the LF-NMR showed that the increased IDF in the noodles resulted in a contraction of relaxation time and an increase in the proportion of loosely bound water.At a high amount of IDF,the water absorption and tensile distance of the noodles significantly decreased and the cooking loss rate increased,with a downward trend in peak viscosity,final viscosity and setback values.Moreover,IDF could improve the storage modulus and loss modulus of sheeted dough and enhance the texture of noodles.Furthermore,the correlations between IDF addition amounts and rheological properties as well as cooking properties were analyzed,and the results confirmed that noodles with the IDF amount of 2%–4%had higher nutrition and quality.This study provides the basis for future development and improvement of IDF-enriched health foods. | Mengxu Lei Jihong Huang Xiaoling Tian Peng Zhou Qi Zhu Limin Li Li Li Sen Ma Xiaoxi Wang | 2021 | Grain & Oil Science and Technology2021，4，1： | 8 |

| 15 | Carbon sequestration processes and mechanisms in coastal mariculture environments in China显示文摘China is the global leader in mariculture production. Increasing sequestered marine carbon(also known as blue carbon) via mariculture activities is a promising approach for mitigating climate change and promoting the development of a low-carbon economy. Mariculture blue carbon is also considered an important component of China's 'sea granary'. In addition to shellfish and macroalgae yields, which represent carbon removed from mariculture environment, blue carbon also includes other important components, which have been largely neglected in the past, such as the carbon transformed by microbes,dissolved organic carbon(mainly referred to as recalcitrant dissolved organic carbon), and sedimentary particulate carbon. Hence,from different aspects, a comprehensive study on the formation processes and mechanisms of carbon sequestration is of great significance for comprehensively unveiling the carbon sequestration capability in coastal mariculture environment, which will contribute to the sustainable development of the fishery economy and construction of an ecological civilization. Moreover, it may add significant economic benefits to the future carbon-trading market. | ZHANG YongYu ZHANG JiHong LIANG YanTao LI HongMei LI Gang CHEN Xiao ZHAO Peng JIANG ZengJie ZOU DingHui LIU XiaoYong LIU JiHua | 2017 | Science China Earth Sciences2017，60，12： | 7 |
| 16 | Complete three-dimensional coseismic displacements due to the 2021 Maduo earthquake in Qinghai Province,China from Sentinel-1 and ALOS-2 SAR images显示文摘On 22 nd May 2021(local time),an earthquake of M_(s)7.4 struck Maduo county in Qinghai Province,China.This was the largest earthquake in China since the 2008 Wenchuan earthquake.In this study,ascending/descending Sentinel-1 and advanced land observation satellite-2(ALOS-2)synthetic aperture radar(SAR)images were used to derive the three-dimensional(3-D)coseismic displacements of this earthquake.We used the differential interferometric SAR(In SAR,DIn SAR),pixel offset-tracking(POT),multiple aperture In SAR(MAI),and burst overlap interferometry(BOI)methods to derive the displacement observations along the line-of-sight(LOS)and azimuth directions.To accurately mitigate the effect of ionospheric delay on the ALOS-2 DIn SAR observations,a polynomial fitting method was proposed to optimize range-spectrum-split-derived ionospheric phases.In addition,the 3-D displacement field was obtained by a strain model and variance component estimation(SM-VCE)method based on the high-quality SAR displacement observations.Results indicated that a left-lateral fault slip with the largest horizontal displacement of up to 2.4 m dominated this earthquake,and the small-magnitude vertical displacement with an alternating uplift/subsidence pattern along the fault trace was more concentrated in the near-fault regions.Comparison with the global navigation satellite system data indicated that the SM-VCE method can significantly improve the accuracy of the displacements compared to the classical weighted least squares method,and the incorporation of the BOI displacements can substantially benefit the accuracy of north-south displacement.In addition to the displacements,three coseismic strain invariants calculated based on the strain model parameters were also investigated.It was found that the eastern and western parts of the faults suffered more significant strains compared with the epicenter region. | Jihong LIU Jun HU Zhiwei LI Zhangfeng MA Lixin WU Weiping JIANG Guangcai FENG Jianjun ZHU | 2022 | Science China Earth Sciences2022，65，4： | 6 |
| 17 | Electroacupuncture reduces injury to the blood-brain barrier following cerebral ischemia/reperfusion injury显示文摘This study used electroacupuncture at Renzhong (DU26) and Baihui (DU20) in a rat model of cerebral ischemia/reperfusion injury. Neurological deficit scores, western blotting, and reverse transcription-PCR results demonstrated that electroacupuncture markedly reduced neurological deficits, decreased corpus striatum aquaporin-4 protein and mRNA expression, and relieved damage to the blood-brain barrier in a rat model of cerebral ischemia/reperfusion injury. These results suggest that electroacupuncture most likely protects the blood-brain barrier by regulating aquaporin-4 expression following cerebral ischemia/reperfusion injury. | Yongjun Peng Hesheng Wang Jianhua Sun Li Chen Meijuan Xu Jihong Chu | 2012 | Neural Regeneration Research2012，7，36： | 6 |
| 18 | Trastuzumab plus adjuvant chemotherapy for human epidermal growth factor receptor 2(HER2)-positive early-stage breast cancer: A real-world retrospective study in Chinese patients显示文摘Objective: To assess the long-term effectiveness and safety of trastuzumab in adjuvant therapy for Chinese patients with early-stage human epidermal growth factor 2(HER2)-positive breast cancer in a real-world setting.Methods: This retrospective observational study analyzed the medical records of HER2-positive breast cancer patients between 2000 and 2012 at the Chinese Academy of Medical Sciences. Patients who received adjuvant chemotherapy alone or adjuvant chemotherapy followed by/combined with trastuzumab were included. The Kaplan-Meier method was used to estimate disease-free survival(DFS) and overall survival(OS). Hazard ratios(HR) and 95% confidence intervals(95% CI) were calculated using the Cox regression model.Results: Of the 1,348 patients analyzed, 909 received chemotherapy alone and 439 received chemotherapy plus trastuzumab. The 3-year, 5-year and 10-year DFS rates were 83.70%, 76.38% and 68.94%, respectively, in the chemotherapy-alone cohort, and 90.21%, 86.19% and 83.45% in the chemotherapy plus trastuzumab cohort. The3-year, 5-year and 10-year OS rates were 96.10%, 91.40% and 81.88% in the chemotherapy-alone cohort, and98.17%, 94.91% and 90.01% in the chemotherapy plus trastuzumab cohort. The chemotherapy plus trastuzumab group had a significantly lower risk of disease recurrence and death than the chemotherapy-alone group(DFS:HR=0.50, 95% CI, 0.37-0.68;P<0.001;OS: HR=0.53, 95% CI, 0.34-0.81;P=0.004) after adjusting for covariates.In the 439 patients treated with trastuzumab, multivariate analysis suggested that lymph node positivity, higher T stages, and hormone receptor-negative status were significantly associated with higher risks of disease recurrence,and lymph node positivity and hormone receptor-negative status were significantly associated with higher risks of death. Grade 3/4 adverse events(incidence ≥1%) were more common in patients receiving trastuzumab(54.44% vs.15.73%).Conclusions: Early-stage HER2-positive breast cancer patients treated with trastuzumab plus adjuvant chemotherapy have a significant survival benefit compared with chemotherapy-alone in real-world settings. Lymph node positivity, hormone receptor-negative status, and higher T stages may be associated with higher risks of recurrence, and effective therapy for patients with these factors is required. | Jihong Guo Qing Li Pin Zhang Peng Yuan Jiayu Wang Fei Ma Ying Fan Ruigang Cai Yang Luo Qiao Li Binghe Xu | 2019 | Chinese Journal of Cancer Research2019，31，5： | 6 |
| 19 | Low frequency oscillation characteristics of East China Power Grid after commissioning of Huai-Hu ultra-high voltage alternating current project显示文摘The low frequency oscillation characteristics of East China Power Grid after commissioning of the first ultra-high voltage alternating current(UHVAC)project-the Huai-Hu UHVAC project are studied.Several low frequency oscillation cases occurred in East China Power Grid in the past few years are reviewed and summarized.Based on the analysis of the different typical operation modes,the main low frequency oscillation modes in East China Power Grid in the early stages of development of ultra-high voltage(UHV)are summarized,and the impacts of the significant power grid maintenance on low frequency oscillation characteristics are analyzed.Besides,the oscillation mode of UHV generators to East China Power Grid is researched,and the importance of the power system stabilizator(PSS)is emphasized.Furthermore,the comparative analysis between the time domain and the frequency domain is carried out,and the influences of the governing system on low frequency oscillation characteristics are revealed.Finally,both the focus and the direction of low frequency oscillation research are presented. | Chao WANG Yang LV Hongyang HUANG Jing ZHANG Jihong LI Yingyi LI Weizhen SUN Yong CHANG | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，3： | 6 |
| 20 | Changing the strategy and culture of stroke awareness education in China: implementing Stroke 1-2-0显示文摘This project implemented the Stroke1-2-0 stroke awareness programme across China and investigated its impact over a 2-year period.We initiated the Stroke1-2-0 educational campaign and Stroke1-2-0 special task forces(STF)across the nation.Massive media coverage,community-based educational sessions with videos and other related materials and induction of Stroke1-2-0 STF were the major means of promotion.We delivered a survey at the end of 2016 and 2018 to evaluate the impact of our effort.A total of 3066 participants responded to the first survey in 2016,and 15207 participants responded in 2018 across China.The acceptance rate for Stroke1-2-0 versus FAST(an English-language stroke awareness tool)was 50.2%versus 19.1%in 2016,and changed significantly to 82.2%versus 8.0%in 2018(p<0.001).Stroke1-2-0 was well accepted by all ages and by people with different academic qualifications.Only 6.5%of survey respondents were aware that there was a therapeutic window for thrombolytic therapy in 2016,but this awareness increased significantly to 32.8%in 2018.Only 12.6%of people in 2016 indicated that they would send patients with stroke to the nearest hospital capable of performing thrombolytic therapy,but there was a nearly threefold increase(52.5%)in this number by 2018.More than 1000 major hospitals joined the Stroke1-2-0 STF,and more than 20000‘stroke warriors’have joined our stroke awareness improvement effort so far.Stroke1-2-0 stroke awareness programme is well-implemented and accepted,and is generating profound improvement in stroke awareness in China. | Jing Zhao Xutong Li Xiaochuan Liu Yuming Xu Jihong Xu Anding Xu Yongjun Wang Renyu Liu | 2020 | Stroke & Vascular Neurology2020，5，4： | 6 |
