| 1 | Mesenchymal stem cell treatment improves outcome of COVID-19 patients via multiple immunomodulatory mechanisms显示文摘The infusion of coronavirus disease 2019(COVID-19)patients with mesenchymal stem cells(MSCs)potentially improves clinical symptoms,but the underlying mechanism remains unclear.We conducted a randomized,single-blind,placebo-controlled(29 patients/group)phase II clinical trial to validate previous findings and explore the potential mechanisms.Patients treated with umbilical cord-derived MSCs exhibited a shorter hospital stay(P=0.0198)and less time required for symptoms remission(P=0.0194)than those who received placebo.Based on chest images,both severe and critical patients treated with MSCs showed improvement by day 7(P=0.0099)and day 21(P=0.0084).MSC-treated patients had fewer adverse events.MSC infusion reduced the levels of C-reactive protein,proinflammatory cytokines,and neutrophil extracellular traps(NETs)and promoted the maintenance of SARS-CoV-2-specific antibodies.To explore how MSCs modulate the immune system,we employed single-cell RNA sequencing analysis on peripheral blood.Our analysis identified a novel subpopulation of VNN2+hematopoietic stem/progenitorlike(HSPC-like)cells expressing CSF3R and PTPRE that were mobilized following MSC infusion.Genes encoding chemotaxis factors—CX3CR1 and L-selectin—were upregulated in various immune cells.MSC treatment also regulated B cell subsets and increased the expression of costimulatory CD28 in T cells in vivo and in vitro.In addition,an in vivo mouse study confirmed that MSCs suppressed NET release and reduced venous thrombosis by upregulating kindlin-3 signaling.Together,our results underscore the role of MSCs in improving COVID-19 patient outcomes via maintenance of immune homeostasis. | Rongjia Zhu Tingdong Yan Yingmei Feng Yan Liu Hongcui Cao Gongxin Peng Yanlei Yang Zhen Xu Jingqi Liu Wei Hou Xiaoyue Wang Zhe Li Luchan Deng Shihua Wang Jing Li Qin Han Hongling Li Guangliang Shan Yinghao Cao Xingyan An Jianshe Yan Zhonghui Zhang Huafei Li Xuebin Qu Jiaqi Zhu Shumin Zhou Jiao Wang Fengchun Zhang Jinming Gao Ronghua Jin Dayong Xu Yan-Qing Ma Tao Huang Shuang Peng Zhi Zheng Ilia Stambler Eric Gilson Lee Wei Lim Alexey Moskalev Antonio Cano Sasanka Chakrabarti Brun Ulfhake Huanxing Su Haoying Xu Sihuan Xu Feng Wei Holly MBrown-Borg Kyung-Jin Min Georgina Ellison-Hughes Calogero Caruso Kunlin Jin Robert Chunhua Zhao | 2021 | Cell Research2021，31，12： | 5 |

| 3 | The temporal dynamics of antimicrobial-resistant Salmonella enterica and predominant serovars in China显示文摘Salmonella enterica is one of the most common bacterial pathogens in humans and animals.Systematic studies on the trends and geographical distribution of antimicrobial-resistant Salmonella and dominant serovars have been well studied in European and American countries while not in China.Here,taking the One-Health strategy,we used>35000 Salmonella enterica isolates to explore the temporal and spatial dynamics of dominant serovars in China.We found that Salmonella Typhimurium was the dominant serovar causing human infection in China,which was consistent with Australia but inconsistent with North American and European countries.The proportion of Salmonella serovars Typhimurium,London,Rissen,Corvallis,Meleagridis,Kentucky,and Goldcoast showed an increasing trend during 2006-2019.We randomly selected 1962 isolates for comparative genomics and antimicrobial resistance studies and found that the number of antibiotic resistance genes(ARGs)per isolate increased 1.84 and 2.69 times of human and non-human origins,respectively,spanning 14 years.The proportion of antimicrobial-resistant Salmonella isolates had an increasing trend during 2006-2019,especially beta-lactam,quinolone,tetracycline,and rifampicin resistance.Moreover,we found that higher diversity of sequence types(STs)in S.Typhimurium than in other serovars,ST34 from pig and ST 19 from chicken origin,were mainly associated with isolates causing child and adult gastro-infection,respectively.Our results fill in the data gap on the trends of dominant serovars and antimicrobial resistance of Salmonella enterica in China.These data provide useful information for public health decision-makers prioritizing interventions for foodborne diseases and food safety. | Yanan Wang Yue Liu Na Lyu Zhiyuan Li Sufang Ma Demin Cao Yuanlong Pan Yongfei Hu Hua Huang George F.Gao Xuebin Xu Baoli Zhu | 2023 | National Science Review2023，10，3： | 4 |
| 4 | Transforming growth factor β1 is a differentially expressed candidate protein of congestive heart failure with Qi-deficiency-blood-stasis syndrome显示文摘OBJECTIVE: To investigate the role of tongue coating fluid protein in regulation of congestive heart failure(CHF) in Qi-deficiency-blood-stasis syndrome.METHODS: We studied patients with CHF(3 patients with Qi-deficiency-blood-stasis syndrome and 3 without Qi-deficiency-blood-stasis syndrome) to investigate differentially expressed proteins. We also included a control group. A biotin label-based antibody array was used for testing tongue coating fluid samples from patients. Net-work analysis of these differentially expressed proteins was conducted using the STRING database,which can predict the relations between differentially expressed proteins and CHF with Qi-deficiency-blood-stasis syndrome.RESULTS: A total of seven differentially expressed proteins were identified, and among these, transforming growth factor β1(TGF-β1) gets a particular attention for us has drawn specific attention.Network analysis showed a homologous relationship of TGF-β1 with bone morphogenetic protein15, which is associated with myocardial fibrosis.CONCLUSION: Occurrence and development of CHF may result from certain DE-proteins and associated signaling pathways. TGF-β1 protein may be a candidate marker for assessing the risk of CHF in Qideficiency-blood-stasis syndrome. | Li Xiaoqian Huang Pinxian Wang Shijun Cao Xuebin He Jiancheng | 2020 | Journal of Traditional Chinese Medicine2020，40，2： | 3 |
| 5 | Effects of strain rates on dynamic deformation behavior of Cu-20Ag alloy显示文摘Copper alloy is widely used in high-speed railway,aerospace and other fields due to its excellent electrical conductivity and mechanical properties.High speed deformation and dynamic loading under impact load is a complex service condition,which widely exists in the field of national defense,military and industrial application.Therefore,the dynamic deformation behavior of the Cu-20Ag alloy was investigated by Split Hopkinson Pressure Bar(SHPB)with the strain rates of 1000-25000 s^(-1),high-speed hydraulic servo material testing machine with the strain rates of 1-500 s^(-1).The effect of strain rate on flow stress and adiabatic shear sensitivity was analyzed.The results show that the increase of strain rate will increase the flow stress and critical strain,that is to say,the increase of strain rate will reduce the adiabatic shear sensitivity of the Cu-20Ag alloy.The Cu-Ag interface has obvious orientation relationship with;(111)_(Cu)//(111)_(Ag):(^(-)111)_(Cu)//(^(-)111)_(Ag):(^(-)200)_(Cu)//(^(-)200)_(Ag) and [0^(-)11]_(Cu)//[0^(-)11]_(Ag) with the increase of strain rate.The increase of strain rate promotes the precipitation of Ag and increases the number of interfaces in the microstructure,which hinders the movement of dislocations and improves the stress and yield strength of the Cu-20Ag alloy.The concentration and distribution density of dislocations and the precipitation of Ag were the main reasons improve the flow stress and yield strength of the Cu-20Ag alloy. | Kexing Song Yongfeng Geng Yijie Ban Yi Zhang Zhou Li Xujun Mi Jun Cao Yanjun Zhou Xuebin Zhang | 2021 | Journal of Materials Science & Technology2021，，20： | 3 |

| 7 | Rice seeds identification based on back propagation neural network model显示文摘Rice quality directly affects the final rice yield.In order to achieve rapid,non-destructive testing of rice seeds,this paper combines the three-dimensional laser scanning technology and back propagation(BP)neural network algorithm to build a rice seeds identification platform.The information on rice seed surface is collected from four angles and processed using Geomagic Studio software.Based on the noise filtering,smoothing of the point cloud,vulnerability repair,and downsampling,the three-dimensional(3D)morphological characteristics of a rice seed surface,and the projection features of the main plane cross-section are obtained through the calculation of the features.The experiments were performed on five rice varieties,including Da Hua aromatic glutinous,Hong ShiⅠ,Tian You VIII,Xin Dao X,and Yu Jing VI.The resulting input vector consisted respectively of:(1)nine 3D morphological surface features,(2)nine projection features of the main cross-section plane of rice,and(3)all of the above features.The results showed that for an input vector consisting of nine surface 3D morphological features,the recognition rate of the five rice varieties was 95%,96%,87%,93%,and 89%,respectively;for an input vector consisting of nine projection features of the main cross-section plane of rice seeds,the recognition rate was 96%,96%,90%,92%,and 89%,respectively;and lastly,for an input vector consisting of all the features,the highest recognition rate of 96%,97%,91%,94%,and 90%,respectively,was achieved.The analysis showed that rice varieties could be identified by using 3D laser scanning.Therefore,the proposed method can improve the accuracy of rice varieties identification. | Xuebin Feng Peijun He Huaxi Zhang Wenqing Yin Yan Qian Peng Cao Fei Hu | 2019 | International Journal of Agricultural and Biological Engineering2019，12，6： | 1 |
| 8 | Optimization of different intensities of exercise preconditioning in protecting exhausted exercise induced heart injury in rats显示文摘This study was to optimize the exercise preconditioning(EP)intensity in protecting from exhaustive exercise-induced cardiac injury(EECI).A total of 98 male Sprague-Dawley rats were divided into 7 groups(n=14):the control group(C),the exhaustive exercise group(EE)and the EP+EE groups,which include the V10(53.0%VO_(2max)),V15(58.4%VO_(2max)),V20(67.0%VO_(2max)),V26(74.0%VO_(2max))and V30(80.0%VO_(2max))groups.Except the C group,the other groups were subjected to treadmill running.The serum contents of N terminal pro B type natriuretic peptide(NT-proBNP)and cardiac troponin I(cTn-I)were detected by the enzyme-linked immunosorbent assay method,ECG was recorded,heart function was detected by pressure volume catheter and the activities of mitochondrial electron transfer pathway(ET pathway)complexesⅠ,ⅡandⅣwere measured by high-resolution respiration instrument.Compared to the EE group,the EP groups have shown decrease of NT-proBNP and cTn-I,improvement of mitochondrial respiratory function and car-diac function.Compared to other EP groups,the V26 group has shown significant decrease of myocardial enzymes and improvement of mitochondrial function.The correlation analysis showed the EP effect was proportional to EP intensity in the range of 53.0%VO_(2max)-74.0%VO_(2max).High intensity and long duration of exhaustive exercise caused cardiac injury and EP could decrease serum level of NT-proBNP and cTn-I,improve electrical derangement and the left ventricular function,and raise the activities of ET pathway complexesⅠ,ⅡandⅣ.The protection of EP on EECI was improved as the EP intensity was increased from 53.0%VO_(2max)to 74.0%VO_(2max)and when EP intensity was 74.0%VO_(2max),the effect was the most obvious among all the setting EP groups. | Zheng Ping Weijia Qiu Mei Yang Xiaoli Zhang Dongying Wang Peng Xu Ziwen Wang Xuebin Cao | 2021 | Sports Medicine and Health Science2021，3，4： | 0 |
| 9 | The early percutaneous coronary intervention in elderly patients with acute coronary syndrome显示文摘It is challenging to undo early percutaneous intervention(PCI)in the elderly with acute coronary syndrome(ACS).Fifteen patients older than 65 years with ACS within 24 hours of the event were admitted from April 4,2004 to December 12,2005.All the patients had early percutaneous coronary intervention and were followed up for 6-12 months by telephone or in the out-patient department.Nine of the 15 patients exhibited acute myocardial infarction(AMI).Six exhib-ited unstable angina(UA).All the patients had early PCI.The average door-to-balloon time was 78 minutes(40-110 minutes).The average PCI time was 99 minutes(68-120 minutes).Nineteen of 36 lesions in the fifteen angioplasty patients were treated and 20 stents were implanted in total.All the procedures were considered successful.Neither deaths nor recurrent angina occurred in the 6-12 months of follow-up.It was shown that early PCI might be an effective and safe method to treat eld-erly patients with ACS. | Xiong HUANG Xuebin CAO Gang ZHANG | 2008 | Frontiers of Medicine2008，2，1： | 0 |
| 10 | Incidence of Major Adverse Cardiovascular and Cerebrovascular Events in Chinese Patients Undergoing Percutaneous Coronary Intervention with Iodixanol: An Observational Postauthorization Study显示文摘Objective:This study aimed to evaluate the major adverse cardiovascular and cerebrovascular events(MACCEs)and overall safety profile associated with iodixanol in Chinese patients undergoing percutaneous coronary intervention(PCI).Methods:Patients at 30 centers in China registered in the OpenClinic v3.6 database from October 30,2013,to October 7,2015,were included in the study.The primary endpoint was in-hospital MACCEs including target lesion revascularization(TLR),stroke,stent thrombosis,cardiac death,and PCI-related myocardial infarction(MI)within 72 h post-PCI.Secondary endpoints were MACCEs from 72 h to 30 d post-PCI and other safety events within 30 d post-PCI.Results:A total of 3,042 patients were enrolled.The incidence of MACCEs within 72 h post-PCI was 2.33%(n=71),including cardiac death(0.03%,n=1)and PCI-related MI(2.30%,n=70).The incidence of MACCEs from 72 h to 30 d post-PCI was 0.16%(n=5),including cardiac death(0.10%,n=3),PCI-related MI(0.03%,n=1),and TLR for stent thrombosis(0.03%,n=1).The incidence of composite angiographic or procedural complications was 2.86%(n=87);233(7.86%)patients had results suggesting contrast-induced acute kidney injury.Conclusions:These findings indicate that the use of iodixanol in Chinese patients undergoing PCI is associated with a low incidence of MACCEs,confirming its safety in this population. | Xiaozeng Wang Dengfeng Ma Tianchang Li Bao Li Xi Su Yanqing Wu Zhimin Du Zheng Ji Ping Yang Baisong Yang Xuebin Cao Junxia Li Fengxia Hou Ziping Cheng Banglong Xu Yaling Han | 2023 | Cardiology Discovery2023，3，2： | 0 |
