| 1 | Understanding SARS-CoV-2-Mediated Inflammatory Responses: From Mechanisms to Potential Therapeutic Tools显示文摘Currently there is no effective antiviral therapy for SARS-CoV-2 infection, which frequently leads to fatal inflammatory responses and acute lung injury. Here, we discuss the various mechanisms of SARS-CoV-mediated inflammation. We also assume that SARS-CoV-2 likely shares similar inflammatory responses. Potential therapeutic tools to reduce SARS-CoV-2-induced inflammatory responses include various methods to block FcR activation. In the absence of a proven clinical FcR blocker, the use of intravenous immunoglobulin to block FcR activation may be a viable option for the urgent treatment of pulmonary inflammation to prevent severe lung injury. Such treatment may also be combined with systemic anti-inflammatory drugs or corticosteroids. However, these strategies, as proposed here, remain to be clinically tested for effectiveness. | Yajing Fu Yuanxiong Cheng Yuntao Wu | 2020 | Virologica Sinica2020，35，3： | 54 |

| 3 | Allogeneic hematopoietic stem cell transplantation for patients with acute leukemia显示文摘Objective: The purposes of this study were to assess the efficacy of allogeneic hematopoietic stem cell transplantation (HSCT) for acute leukemia (AL) and analyze the factors affecting the prognosis of these patients. Methods: The clinical and follow-up data of 93 AL patients (median age, 30 years) undergoing allogeneic HSCT in Xiangya Hospital over the past 12 years were collected, and the potential factors affecting the efficacy and prognosis of allogeneic HSCT patients were determined. Results: Hematopoietic reconstitution was achieved in 90 patients. At the last follow-up, the incidences of severe acute graft versus host disease (aGvHD) and extensive chronic GvHD (cGvHD) were 14.0% and 20.0%, the 3-year cumulative incidence of transplantation related mortality (TRM) and relapse rate were 16.8%±6.1% and 21.3%±6.7%, and the estimated 3-year overall survival (OS) and disease-free survival (DFS) of the patients were 64.6%±5.4% and 56.5%±5.5%, respectively. Univariate analysis indicated that age older than 40 years, HLA mismatch, and severe lung infection within the first 100 days after transplantation were risk factors for severe aGvHD, age older than 40 years, HLA mismatch, severe lung infection within the first 100 days after transplantation, and severe aGvHD were risk factors for TRM, high-risk AL and lack of cGvHD were risk factors for relapse (all P<0.05). Survival estimation showed that HLA mismatch, severe lung infection occurring within the first 100 days post-transplantation, high-risk AL severe aGvHD and lack of cGvHD were risk factors associated with poor prognosis (all P<0.05). Further multivariate analyses revealed that severe lung infection within the first 100 days post-transplantation, severe aGvHD and lack of cGvHD were independent risk factors for unfavorable outcomes (all P<0.05). Conclusions: Allogeneic HSCT can improve the DFS of AL patients, and severe lung infection within the first 100 days post-transplantation, severe aGvHD and lack of cGvHD are independent risk factors affecting the prognosis. | Yan Chen Yajing Xu Gan Fu Yi Liu Jie Peng Bin Fu Xiaoyu Yuan Hongya Xin Yan Zhu Qun He Dengshu Wu Yigang Shu Xiaolin Li Xielan Zhao Fangping Chen | 2013 | Chinese Journal of Cancer Research2013，25，4： | 3 |
| 4 | Flotation performance of a novel Gemini collector for kaolinite at low temperature显示文摘How to sustainably produce bauxite by effective reverse froth flotation of kaolinite at low temperature is an urgent problem to be solved in the field of mineral processing.In this work,a novel amino-based Gemini surfactant butadiyl-1,4-bis(dimethyl dodecylammonium bromide)(BBDB) was prepared and first utilized as a novel collector for kaolinite flotation.Its flotation performance for kaolinite was compared with that of the common monomolecular surfactant 1-dodecylamine(DDA) by micro-flotation tests.The tests results indicated that 95% kaolinite recovery was obtained using 2.0×10^(-4) mol/L BBDB at 25℃ which was half of the dosage when DDA obtained the maximum kaolinite recovery of81%.At extremely low temperature(0℃),3.0×10^(-4) mol/L BBDB could still collect 91% kaolinite,while DDA showed a frustrating ability.The contact angle tests indicated that BBDB could still significantly improve the hydrophobicity of the kaolinite surface(contact angle 71.7°) than DDA(contact angle only25.8°) at 0℃.The Krafft point comparison tests indicated that BBDB had a much lower Krafft point(below0℃) than DDA.Fourier transform infrared spectroscopy(FTIR)-spectrum analysis and zeta potential measurements showed that BBDB was physically adsorbed on the surface of kaolinite through electrostatic interaction. | Shiyong Zhang Zhiqiang Huang Hongling Wang Rukuan Liu Chen Cheng Shuyi Shuai Yajing Hu Zhiqun Guo Xinyang Yu Guichun He Weng Fu | 2021 | International Journal of Mining Science and Technology2021，31，6： | 2 |
| 5 | 2021 Chinese consensus on the diagnosis and management of primary immune thrombocytopenia in pregnancy显示文摘Immune thrombocytopenia(ITP)is an acquired disease characterized by isolated thrombocytopenia,which is one of the most common causes of thrombocytopenia during pregnancy.Women with ITP who have severe thrombocytopenia are at an increased risk for life-threatening obstetric complications.Therefore,we established this consensus statement on the diagnosis and management of ITP during pregnancy(detailed information is available in the Supplementary File,http://gffzz16e312a87a7141a5hc5qkpuq9vf0p6b0u.ffgz.tsg.suse.edu.cn/A978). | Zhang Xiaohui Chen Fangping Chen Xiequn Cheng Yunfeng Fang Meiyun Feng Jianming Fu Haixia Gao Hong Han Yue He Aili Hou Ming Hu Yu Huang Ruibin Huang Wenrong Jing Zhicheng Kong Peiyan Liang Aibin Liang Meiying Liu Daihong Liu Junling Liu Lin Liu Xiaowei Ma Liangming Mei Heng Ni Heyu Niu Ting Peng Jun Qiao Jianlin Ren Jinhai Song Yongping Tang Liang V Tong Tong Wang Shaoyuan Wang Xin Wang Zhao Wei Hui Wu Depei Wu Guangsheng Xu Caigang Xu Xue Xu Yajing Yang Linhua Yang Renchi Yang Tonghua Yin Chenghong Yu Li Zhang Guangsen Zhang Lei Zhang Liansheng Zhang Xi Zhao Weili Zhao Yongqiang Zhou Daobin Zhou Hu Zhou Zeping Zhu Tienan Wang Jianliu Huang Xiaojun | 2022 | Chinese Medical Journal2022，，8： | 2 |
| 6 | Process of Analyzing Pig Inbreeding Coefficient Using SAS Program显示文摘The paternity index is one of the important parameters which paternity determination depends on.Inbreeding is an indispensable and effective means to improve herds and breeds and breed new strains and breeds.It can fix good traits and improve herd genetic uniformity.The INBREED module of SAS statistical analysis software can be used to calculate the inbreeding coefficients of the offspring and their parents in the pig herd pedigree.In this study,we used actual data as an example to compile and operate an SAS program for calculating the inbreeding coefficients of a pig herd.Compared with the dedicated software for calculating inbreeding coefficients developed in recent years,such as BASIC+database dBASE,Visual Basic+database SQ L Serve method,DFREMLI,MTDF EMLI,VCE,ASREML,DMU,GBS and Herdsman,calculating inbreeding coefficients with SAS programs has the advantages of low cost,simple programming language,and easy operation.For livestock breeders who are not provided with special computing software,the use of SAS to calculate the inbreeding coefficients of pigs is of great significance to planned breed selection and assortative mating. | Xuelin FU Junyong HU Yajing CHEN Tingting WU Wanghong LIU | 2021 | Agricultural Biotechnology2021，10，3： | 1 |

| 8 | Study on the Accuracy of Different CASA Systems in the Quality Detection of Fresh Boar Semen显示文摘[Objectives]This study was conducted to compare and analyze the accuracy of computer-aided sperm analysis(CASA)and manual method for detecting the quality of fresh boar semen at room temperature.[Methods]Statistical methods such as analysis of variance,ZB score and Z score were used to compare the accuracy of five different brands of CASA systems and manual method to detect the vitality and density of fresh boar semen at room temperature.[Results]After setting the parameters of five CASA systems the same as follows:VCL(curvilinear velocity),VSL(straight-line velocity)≥5μm/s,STR(straightness)=VSL(straight-line velocity)/VAP(average path velocity)≥25%,the sperm motility of six parts of boar semen was tested at normal temperature using different brands of special fixed-volume slides with a uniform chamber height[(20±2)μm].There were no significant differences in sperm vitality detected by the five CASA systems(P>0.05).The ZB scores of the vitality obtained by observers or instrument engineers who did not have a job certificate from the quality inspection department showed that the results of three observers or instrument engineers were unsatisfactory(∣ZB∣>3),but there were no significant differences in vitality between the CASA systems and the inspector with a job certificate(P>0.05).Regarding sperm density detection,when the sperm density was less than 280×106/ml,there were no significant differences between the results displayed by the instruments and the results of the manual hemocytometer counting(P>0.05).[Conclusions]The accuracy of the CASA systems set to uniform parameters was consistent with the accuracy of the visual vitality obtained by an inspector with a job certificate.When the semen was diluted with 3%NaCl solution to a sperm density<280×10^6/ml,the sperm density detected by the CASA systems was consistent in reliability with that obtained by the hemocytometer detection.The CASA systems are faster and more efficient and objective than manual detection,and have the advantages of strong operability and easy promotion. | Xuelin FU Hongjie YANG Yajing CHEN Xin XIA Manting WU Tingting WU Wanghong LIU | 2020 | Agricultural Biotechnology2020，9，6： | 1 |
| 9 | Analysis of York Pigs Feeding Behavior Using Stepwise Regression and Principal Component Regression显示文摘A statistical analysis was conducted on the feeding behavior of 106 York breeding pigs.Pearson correlation analysis,principal component correlation analysis and multiple stepwise regression equation methods were applied to establish regression equations of the York breeding pigs total feed intake per time and average feed intake per time with corrected fat thickness,feed conversion rate,and corrected daily gain.The results showed that:①there were three peak feed intake periods for the pigs,and the correlation coefficient between the feed intake and the corrected fat thickness of the pigs in the 24 h period was positive or negative,that is,increasing the number of feeding times and the feed intake was not necessarily conducive to the fat thickness accumulation,but the breeding goal of fat thickness could be achieved by controlling the feeding times and feed intake;②the average feed intake of pigs in the 60-90 kg body weight stage was 30%-50%higher than that of the 30-60 kg body weight stage,but the number of feeding times decreased,the peak feeding time was more concentrated,and the feeding duration per time was 3.0 min longer,indicating that as the weight of pigs increased,the feed intake increased significantly;and③the stepwise regression equations and the principal component equations showed that the feeding behavior of York pigs in the 30-90 kg growth stage was not only affected by the feeding time within 24 h,but also by environmental factors such as temperature and humidity.The feeding behavior of York pigs is a complex process of interaction between environmental factors and animal factors. | Xuelin FU Yajing CHEN Manting WU Junyong HU Wanghong LIU | 2021 | Agricultural Biotechnology2021，10，2： | 1 |
| 10 | Efficient Processing of Skyline Group Queries over a Data Stream显示文摘In this paper, we study the skyline group problem over a data stream. An object can dominate another object if it is not worse than the other object on all attributes and is better than the other object on at least one attribute. If an object cannot be dominated by any other object, it is a skyline object. The skyline group problem involves finding k-item groups that cannot be dominated by any other k-item group. Existing algorithms designed to find skyline groups can only process static data. However, data changes as a stream with time in many applications,and algorithms should be designed to support skyline group queries on dynamic data. In this paper, we propose new algorithms to find skyline groups over a data stream. We use data structures, namely a hash table, dominance graph, and matrix, to store dominance information and update results incrementally. We conduct experiments on synthetic datasets to evaluate the performance of the proposed algorithms. The experimental results show that our algorithms can efficiently find skyline groups over a data stream. | Xi Guo Hailing Li Aziguli Wulamu Yonghong Xie Yajing Fu | 2016 | Tsinghua Science and Technology2016，21，1： | 1 |
| 11 | Photosynthetic Characteristics in Two Near Isogenic Lines of Winter Wheat显示文摘The development of near isogenic lines(NILs) is an important tool for physiological dissection of drought resistance in wheat. To better understand the potential for improving grain yield, a split-plot experiment was conducted under a mobile rain shelter using NILs of winter wheat with significant differences in the photosynthetic rate: the 908120 line with a high photosynthetic rate and the 908206 line with a low photosynthetic rate. The results indicated that the net photosynthesis rate(Pn), stomatal conductance, and transpiration rate in flag leaves in line 908120 were significantly higher than that in line 908206 under uniform water treatments during the reproductive phase in replicated pooled-culture trials. The maximum quantum yield Fv/Fm value and ribulose-1,5-bisphosphate carboxylase/oxygenase(RuBPCase) activity value were higher in line 908120 than that in line 908206, whereas the intercellular CO_2 and cell membrane permeability in line 908120 were lower than that in line 908206. Higher leaf Pn, transpiration rate, and RuBPCase activity and lower membrane ion leakage rate ensured the robustness of line 908120 during times of irrigation and drought, which contributed to the maintenance of its high grain yield. Drought had a negative effect on these factors, resulting in decreased yield, and the photosynthesis rate of flag leaves markedly affected the yield in NILs of winter wheat. NILs are an important strategy for wheat adaptation to drought stress, but might not be the only mechanism causing the significant grain yield increase. Collectively, the characteristics of line 908120 resulted in a higher grain yield compared with that of line 908206. Further dissection of the drought avoidance mechanisms in wheat, as well as analysis and identification of the genes involved may be necessary. | Guirong HUANG Xinying ZHANG Yajing WANG Fu FENG Xurong MEI Xiuli ZHONG | 2019 | Agricultural Biotechnology2019，8，2： | 0 |
| 12 | 3D Printing Technology for Short-continuous Carbon Fiber Synchronous Reinforced Thermoplastic Composites:A Comparison between Towpreg Extrusion and In Situ Impregnation Processes显示文摘Three-dimensional(3D)printing of carbon fiber-reinforced thermoplastic composites(CFRTPs)provides an ef-fective method for manufacturing the CFRTPs parts with complex structures.To increase the mechanical per-formance of these parts,a 3D printing technology for short-continuous carbon fiber synchronous-reinforced thermoplastic composites(S/C-CFRTPs)has been proposed.However,the synchronous reinforcement that ex-isted only at particular positions led to a limited improvement in the mechanical performance of the 3D-printed S/C-CFRTP part,which made it challenging to meet the engineering requirements.To solve this problem,two methods for achieving synchronous reinforcement at all the positions of the 3D-printed S/C-CFRTP part are pro-posed.To determine a suitable printing process for the S/C-CFRTP part,a comprehensive comparison between the two methods was conducted through theoretical analysis and experimental verification,involving the print-ing mechanism,fiber content,impregnation percentage,and mechanical performance.The results indicated that the towpreg extrusion process was suitable for manufacturing the 3D-printed S/C-CFRTP part.Compared with the in situ impregnation process,the towpreg extrusion process led to a fiber content increase of approximately 7%and void rate reduction of approximately 6%,resulting in 19%and 20%increases in the tensile and flexural strengths of the 3D-printed S/C-CFRTPs,respectively.Additionally,an optimized process parameter setting for fabricating an S/C-CFRTP prepreg filament with excellent mechanical performance was proposed.The findings of this study can provide a new approach for further improving the mechanical performance of the 3D-printed advanced composites. | Fuji Wang Gongshuo Wang Hongquan Wang Rao Fu Yajing Lei Jianing He | 2023 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2023，2，3： | 0 |

| 17 | Dual-metal zeolite imidazolate framework for efficient lithium storage boosted by synergistic effects and self-assembly 2D nanosheets显示文摘Metal-organic framework materials(MOFs),such as zeolitic imidazolate framework(ZIF),have been widely used in energy storage due to their advantages such as high structural stability,large specific surface,more active sites and skeleton structures.Herein,a novel two-dimensional(2D)Co Cu-ZIF was synthesized by a facile solvothermal method.The as-prepared Co Cu-ZIF nanosheets exhibit an ultrahigh reversible capacity of 2287.4 m Ah/g and remains at 1172.1 m Ah/g after 300 cycles at a current density of 100 m A/g,far better than that of the single Co-ZIF and Cu-ZIF.Additionally,the specific discharge capacity of Co Cu-ZIF nanosheets can maintain at about 590 m Ah/g after 1000 cycles at the current density of 2 A/g.Owing to the synergistic effect of two metals,function of nitrogen in the molecular and selfassembly 2D nanosheets,our research can provide strong support for the practical application of Co Cu-ZIF materials in lithium ion batteries. | Ming Yue Yajing Fu Canping Zhang Junxiao Fu Shiquan Wang Jianwen Liu | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
| 18 | Unmanned aerial vehicle based intelligent triage system in mass-casualty incidents using 5G and artificial intelligence显示文摘BACKGROUND:Rapid on-site triage is critical after mass-casualty incidents(MCIs)and other mass injury events.Unmanned aerial vehicles(UAVs)have been used in MCIs to search and rescue wounded individuals,but they mainly depend on the UAV operator’s experience.We used UAVs and artificial intelligence(AI)to provide a new technique for the triage of MCIs and more efficient solutions for emergency rescue.METHODS:This was a preliminary experimental study.We developed an intelligent triage system based on two AI algorithms,namely OpenPose and YOLO.Volunteers were recruited to simulate the MCI scene and triage,combined with UAV and Fifth Generation(5G)Mobile Communication Technology real-time transmission technique,to achieve triage in the simulated MCI scene.RESULTS:Seven postures were designed and recognized to achieve brief but meaningful triage in MCIs.Eight volunteers participated in the MCI simulation scenario.The results of simulation scenarios showed that the proposed method was feasible in tasks of triage for MCIs.CONCLUSION:The proposed technique may provide an alternative technique for the triage of MCIs and is an innovative method in emergency rescue. | Jiafa Lu Xin Wang Linghao Chen Xuedong Sun Rui Li Wanjing Zhong Yajing Fu Le Yang Weixiang Liu Wei Han | 2023 | World Journal of Emergency Medicine2023，14，4： | 0 |
| 19 | High strength and deformation stability achieved in CrCoNi alloy containing deformable oxides显示文摘Hard secondary phases usually strengthen alloys at the expense of ductility.In this work,we made a dual-phase CrCoNi-O alloy containing a face centered cubic matrix and chromium oxide.On one side,the dispersed chromium oxide nano-particles impeded dislocation movement and increased the strength of the alloy.On another side,the spreading lattice distortion in CrCoNi-O high entropy solution locally relieved the severe interfacial mismatch and led to nanoscale variation of interfacial strain at the matrix-oxide interface,which facilitated dislocations’transmission from one phase to another.Consequently,unlike the strong but brittle oxide nanoparticles used before,the oxide phase here can afford significant dislocation activities during material’s plastic deformation.Comparing the mechanical properties of CrCoNi-O alloys with and without chromium oxide particles,it was found that the yield strength of the dual-phase samples was twice of the single phase CrCoNi-O alloy and strong strain hardening was obtained with ultra-high deformation stability.High density of nanotwins formed in dual-phase samples under high stress,resulting in significant strain hardening according to the well-known twinning-induced plasticity(TWIP)effect.Our results shed light on optimizing the combination of strength and plasticity of compounds by modulating the variation of interfacial strain field based on the spreading lattice distortion. | Jiawei Zou Xiaoqian Fu Yajing Song Tianxin Li Yiping Lu Ze Zhang Qian Yu | 2023 | Journal of Materials Science & Technology2023，，3： | 0 |
