1Guidelines for evaluation and management of cerebral collateral circulation in ischaemic stroke 2017显示文摘Collateral circulation plays a vital role in sustaining blood flow to the ischaemic areas in acute,subacute or chronic phases after an ischaemic stroke or transient ischaemic attack.Good collateral circulation has shown protective effects towards a favourable functional outcome and a lower risk of recurrence in stroke attributed to different aetiologies or undergoing medical or endovascular treatment.Over the past decade,the importance of collateral circulation has attracted more attention and is becoming a hot spot for research.However,the diversity in imaging methods and criteria to evaluate collateral circulation has hindered comparisons of findings from different cohorts and further studies in exploring the clinical relevance of collateral circulation and possible methods to enhance collateral flow.The statement is aimed to update currently available evidence and provide evidence-based recommendations regarding grading methods for collateral circulation,its significance in patients with stroke and methods under investigation to improve collateral flow.Liping Liu Jing Ding Xinyi Leng Yuehua Pu Li-An Huang Anding Xu Ka Sing Lawrence Wong Xin Wang Yongjun Wang 2018Stroke & Vascular Neurology2018,3,3:37
2miR-503-3p promotes epithelialemesenchymal transition in breast cancer by directly targeting SMAD2 and E-cadherin显示文摘Although progress in clinical and basic research has significantly increased our understanding of breast cancer, little is known about the molecular mechanism underlying breast cancer metastasis. Identification of effective therapeutic targets to prevent breast cancer metastasis is urgently needed. The function of mi R-503-3p has been investigated in other cancers, but its role in breast cancer remains undefined.Here, we found that mi R-503-3p was overexpressed in breast cancer tissue and plasma compared with adjacent normal breast tissue and with plasma from healthy individuals. Moreover, we identified mi R-503-3p to be an oncogene of breast cancer cell proliferation, migration and invasion. Upregulation of mi R-503-3p in breast cancer cells inhibited expression of epithelialemesenchymal transition(EMT)-related protein SMAD2 and the epithelial marker protein E-cadherin by directly binding to their m RNA30 untranslated region, whereas increased expression of mesenchymal marker proteins, including vimentin and N-cadherin. Taken together, our findings support a critical role for mi R-503-3p in induction of breast cancer EMT and suggest that plasma mi R-503-3p may be a useful diagnostic biomarker for breast cancer.Zitong Zhao Xinyi Fan Lanfang Jiang Zhongqiu Xu Liyan Xue Qimin Zhan Yongmei Song 2017Journal of Genetics and Genomics2017,44,2:15

6Dosage effect of multiple genes accounts for multisystem disorder of myotonic dystrophy type 1显示文摘Multisystem manifestations in myotonic dystrophy type 1(DM1)may be due to dosage reduction in multiple genes induced by aberrant expansion of CTG repeats in DMPK,including DMPK,its neighboring genes(SIX5 or DMWD)and downstream MBNLh However,direct evidence is lacking.Here,we develop a new strategy to generate mice carrying multigene heterozygous mutations to mimic dosage reduction in one step by injection of haploid embryonic stem cells with mutant Dmpk,Six5 and Mbnll into oocytes.The triple heterozygous mutant mice exhibit adult-onset DM1 phenotypes.With the additional mutation in Dmwd,the quadruple heterozygous mutant mice recapitulate many major manifestations in congenital DM1.Moreover,muscle stem cells in both models display reduced sternness,providing a unique model for screening small molecules for treatment of DM1.Our results suggest that the complex symptoms of DM1 result from the reduced dosage of multiple genes.Qi Yin Hongye Wang Na Li Yifu Ding Zhenfei Xie Lifang Jin Yan Li Qiong Wang Xinyi Liu Liuqing Xu Qing Li Yongjian Ma Yanbo Cheng Kai Wang Cuiqing Zhong Qian Yu Wei Tang Wanjin Chen Wenjun Yang Fan Zhang Chen Ding Lan Bao Bin Zhou Ping Hu Jinsong Li 2020Cell Research2020,30,2:7
7Regulation of non-classical immune parameters in immune thrombocytopenic purpura mice by a spleen-invigorating,qi-replenishing and blood-containing formula显示文摘Objective:This study investigated the regulatory effect of non-classical immune parameters on immune thrombocytopenic purpura(ITP)mice by a spleen-invigorating,qi-replenishing and blood-containing formula(SQBF).Method:A total of 80 BALB/c mice were randomly divided into four equal groups(20 mice each):control group,model group,prednisone group and spleen-invigorating,qi-replenishing and blood-containing(SQBF)group.Mice in the model group,prednisone group,and SQBF group were administered anti-platelet serum to induce ITP.The dynamic variations of platelet counts in ITP mice were measured with an automatic blood analyzer before modeling and 48 h,and 8,12 and 15 days following APS injection.Levels of b-endorphin(b-EP),vasoactive intestinal peptide(VIP)and salivary IgA(SIgA)were detected by enzyme-linked immunosorbent assay(ELISA)on 15th day of experiment.Results:SQBF enhanced peripheral blood platelet counts in ITP mice similar to that of prednisone,and both groups showed a statistically significant response compared with the model group(P<.01).The SQBF significantly decreased b-EP levels compared with the model and prednisone intervention groups(P<.05),significantly increased the levels of VIP and SIgA in ITP mice compared with the model group(P<.05)and had significant protective effects on the thymus of ITP mice compared with the model group(P<.01).Conclusions:The SQBF had a similar effect to prednisone with regards to enhancing peripheral blood platelet counts in ITP mice.Furthermore,it decreased b-EP levels and increased VIP and SIgA,and protected the thymus.This shows that,on base of the brain-gut axis functions,some non-classical immune vascular active factors or neurotransmitters are also involved in immune responses,and also have relationship with the onset of ITP and bleeding and/or hemostasis.It needs further study to determine whether a change in these active factors is related to immediate hemostasis.Tiantian Li Hao He Li Hou Yue Xu Xiaoyong Wu Yanping Sun Lei Zheng Zhixiong Chen Xinyi Chen Bei Qin 2015Journal of Traditional Chinese Medical Sciences2015,2,2:6
8Vertical displacement loading tides and self-attraction and loading tides in the Bohai, Yellow, and East China Seas显示文摘The loading tides are calculated by means of the Green's function method based on a high-resolution regional ocean tide model, the TOPO7.0 global ocean tide model, and the Gutenberg-Bullen A Earth model. The results show that the maximal amplitude of M2 vertical displacement loading (VDL) tide in the Bohai, Yellow, and East China Seas exceeding 28mm appears 150km off the Zhejiang coast; the second maximum exceeding 20mm appears in Inchon Bay; and the third maximum exceeding 14mm is located in the northeast of the North Yellow Sea. The maximal amplitudes of S2 VDL tide at the above three locations exceed 10, 8, and 4mm, respectively. The maximal amplitudes of the K1 and O1 VDL tides, exceeding 13 and 10 mm respectively, appear near the central and north Ryukyu Islands; the amplitudes tend to decease toward the inward areas. The phases of semidiurnal VDL tides are basically opposite to those of corresponding ocean tides. The phases of diurnal VDL tides are basically opposite to those of corresponding ocean tides in the most part of the East China Sea and the eastern part of the South Yellow Sea. This anti-phase relationship generally does not hold in the rest parts of the Bohai and Yellow Seas. The distribution patterns of self-attraction and loading (SAL) tides are very similar to those of VDL tides. The SAL tides have amplitudes about 1.2-1.7 times of the corresponding VDL tides and their phases are basically opposite to the corresponding VDL tides. The maximal amplitude of M2 SAL tide also appears off the Zhejiang coast, with a magnitude exceeding 42mm.FANG GuoHong XU XiaoQing WEI ZeXun WANG YongGang WANG XinYi 2013Science China Earth Sciences2013,56,1:6

10Multi-level multi-area hybrid automatic voltage control system and its trial operation in Northeast China Grid显示文摘In order to coordinate automatic voltage control(AVC)systems of a large interconnected system,a multi-level multi-area hybrid automatic voltage control(MLMA-HAVC)system was constructed.This system began its trial operation in the Northeast China Grid in January 2010,and for the first time in China and abroad it realized automatic close-loop control of multi-area and multi-level interconnected power grid and multi-objective self-approaching optimization in aspects of security,high quality and economic operation.This system has three breakthroughs in theory and engineering application:1)Established the MLMA-HAVC theory to solve multi-objective optimization of large-scale system;2)proposed reactive power/voltage coordination control method to inhibit or further eliminate regional oscillations;3)presented advanced state estimation algorithm to guarantee acquisition of high reliability data.This paper summarizes the basic principle of MLMA-HAVC,and reports engineering realization of MLMA-HAVC system in the Northeast China Grid.ZHANG XueMin MEI ShengWei SU XinYi WANG Gang JIA Wei SHAO GuangHui XU XingWei 2011Science China(Technological Sciences)2011,54,9:6
11Cotidal charts and tidal power input atlases of the global ocean from TOPEX/Poseidon and JASON-1 altimetry显示文摘The global distributions of eight principal tidal constituents, M_2 , S_2 , K_1 , O_1 , N_2 , K_2 , P_1 , and Q_1 , are derived using TOPEX/Poseidon and JASON-1(T/P-J) satellite altimeter data for 16 a. The intercomparison of the derived harmonics at 7000 subsatellite track crossover points shows that the root mean square (RMS) values of the tidal height differences of the above eight constituents range from 1.19 cm to 2.67 cm, with an average of about 2 cm. The RMS values of the tidal height differences between T/P-J solutions and the harmonics from ground measurements at 152 tidal gauge stations for the above constituents range from 0.34 cm to 1.08 cm, and the relative deviations range from 0.031 to 0.211. The root sum square of the RMS differences of these eight constituents is 2.12 cm, showing the improvement of the present model over the existing global ocean tidal models. Based on the obtained tidal model the global ocean tidal energetics is studied and the global distribution of the tidal power input density by tide-generating force of each constituent is calculated, showing that the power input source regions of semidiurnal tides are mainly concentrated in the tropical belt between 30 S and 30 N, while the power input source regions of diurnal tides are mainly concentrated off the tropic oceans. The global energy dissipation rates of the M_2 , S_2 , K_1 , O_1 , N_2 , P_1 , K_2 and Q_1 tides are 2.424, 0.401, 0.334, 0.160, 0.113, 0.035, 0.030 and 0.006 TW, respectively. The total global tidal dissipation rate of these eight constituents amounts to 3.5 TW.WANG Yihang FANG Guohong WEI Zexun WANG Yonggang WANG Xinyi XU Xiaoqing 2012Acta Oceanologica Sinica2012,31,4:5
12Changes in Global Cloud Cover Based on Remote Sensing Data from 2003 to 2012显示文摘As is well known,clouds impact the radiative budget,climate change,hydrological processes,and the global carbon,nitrogen and sulfur cycles.To understand the wide-ranging effects of clouds,it is necessary to assess changes in cloud cover at high spatial and temporal resolution.In this study,we calculate global cloud cover during the day and at night using cloud products estimated from Moderate Resolution Imaging Spectroradiometer(MODIS)data.Results indicate that the global mean cloud cover from 2003 to 2012 was 66%.Moreover,global cloud cover increased over this recent decade.Specifically,cloud cover over land areas(especially North America,Antarctica,and Europe)decreased(slope=–0.001,R^2=0.5254),whereas cloud cover over ocean areas(especially the Indian and Pacific Oceans)increased(slope=0.0011,R^2=0.4955).Cloud cover is relatively high between the latitudes of 36°S and 68°S compared to other regions,and cloud cover is lowest over Oceania and Antarctica.The highest rates of increase occurred over Southeast Asia and Oceania,whereas the highest rates of decrease occurred over Antarctica and North America.The global distribution of cloud cover regulates global temperature change,and the trends of these two variables over the 10-year period examined in this study(2003–2012)oppose one another in some regions.These findings are very important for studies of global climate change.MAO Kebiao YUAN Zijin ZUO Zhiyuan XU Tongren SHEN Xinyi GAO Chunyu 2019Chinese Geographical Science2019,29,2:5
13ROS-responsive cyclodextrin nanoplatform for combined photodynamic therapy and chemotherapy of cancer显示文摘Cyclodextrin(CD) has special spatial structure and well biological safety,so it has been widely used for constructing CD-based na noplatforms.Through functionalization,cyclodextrin can form various stimulusresponse nanoplatforms,such as pH,temperature,redox,light and magnetic fields.In this study,we designed a highly sensitive reactive oxygen species(ROS)-responsive polymer PCP which encapsulated doxorubicin(DOX) and purpurin 18(P18) to achieve the syne rgy of photodynamic and chemotherapy.The high content of reactive oxygen species(ROS) in the tumor microenvironment(TME) triggers the cleavage of the borate bond of MPEG-CD-PHB(PCP),thereby promoting the re lease of drugs.When irradiated with nea rinfrared laser,the photosensitizer P18 released by polymer micelles can produce reactive oxygen species to promote cell apoptosis.Compared with monotherapy,a series of experiments confirmed that our micelles had enhanced anti-cancer activity.This work was beneficial to the design of ROS-responsive materials and provides an effective strategy for the application of collaborative anti-tumor therapy.Die Jia Xianbin Ma Yi Lu Xinyi Li Shengxin Hou Yuan Gao Peng Xue Yuejun Kang Zhigang Xu 2021Chinese Chemical Letters2021,32,1:4
14A universal pipeline for mobile mRNA detection and insights into heterografting advantages under chilling stress显示文摘Heterografting has long been used to enhance the chilling tolerance of temperature-sensitive crops,including watermelon,whose mechanism is known to involve bidirectional long-distance mRNA movements.Despite several studies reporting on mobile mRNA(mb-mRNA)profiles in plants,accurate identification of mb-mRNAs is challenging owing to an array of technical problems.Here,we developed a bioinformatical pipeline that took most of the known technical concerns into consideration and is considered to be a universal tool for mb-mRNA detection in heterografts.By applying this pipeline to a commercial watermelon–bottle gourd heterografting system,we detected 130 and 1144 mb-mRNAs upwardly and 167 and 1051 mb-mRNAs downwardly transmitted under normal and chilling-stress conditions,respectively.Quantitative real-time PCR indicated a high accuracy rate(88.2%)of mb-mRNA prediction with our pipeline.We further revealed that the mobility of mRNAs was not associated with their abundance.Functional annotation and classification implied that scions may convey the stress signal to the rootstock,subsequently triggering energy metabolism reprogramming and abscisic acid-mediated stress responses by upward movement of effective mRNAs,ultimately leading to enhanced chilling tolerance.This study provides a universal tool for mb-mRNA detection in plant heterografting systems and novel insights into heterografting advantages under chilling stress.Ying Wang Lingping Wang Nailin Xing Xiaohua Wu Xinyi Wu Baogen Wang Zhongfu Lu Pei Xu Ye Tao Guojing Li Yuhong Wang 2020Horticulture Research2020,7,1:3
15Rapid,visual,and equipment-free point-of-care testing for Staphylococcus aureus by direct recombinase polymerase amplification with SYBR GreenΙ显示文摘Food-borne diseases mainly caused by bacterial pathogens and the safety of genetically modified(GM)food have become global concerns[1].As a leading bacterial pathogen,Staphylococcus aureus can not only cause a variety of diseases[2]but also contaminate different kinds of animal food products[3].In addition,GM foods whose impact on human health and the natural environment is still a matter of controversy have gradually entered the commercial markets[4].Therefore,many countries have decided to implement labeling regulations for authorized genetically modified organisms(GMOs)to protect the consumers’right to know[5].Hence,it is critical to develop a rapid,simple,equipment-free,and on-site testing method to detect the GM contents in food samples and pathogen to ensure food safety.Xiaorui Fan Fangti Han Binan Zhao Yan Xu Xiao Zhao Xinyi Pu Yanan Du Qi Zhang Xiaoxia Zhang Wanjing Zhang Wenjing Wu Zhiwei Chen Kai Zhao 2021Acta Biochimica et Biophysica Sinica2021,53,9:3
16Retrieval of Land-surface Temperature from AMSR2 Data Using a Deep Dynamic Learning Neural Network显示文摘It is more difficult to retrieve land surface temperature(LST) from passive microwave remote sensing data than from thermal remote sensing data, because the emissivities in the passive microwave band can change more easily than those in the thermal infrared band. Thus, it is very difficult to build a stable relationship. Passive microwave band emissivities are greatly influenced by the soil moisture, which varies with time. This makes it difficult to develop a general physical algorithm. This paper proposes a method to utilize multiple-satellite, sensors and resolution coupled with a deep dynamic learning neural network to retrieve the land surface temperature from images acquired by the Advanced Microwave Scanning Radiometer 2(AMSR2), a sensor that is similar to the Advanced Microwave Scanning Radiometer Earth Observing System(AMSR-E). The AMSR-E and MODIS sensors are located aboard the Aqua satellite. The MODIS LST product is used as the ground truth data to overcome the difficulties in obtaining large scale land surface temperature data. The mean and standard deviation of the retrieval error are approximately 1.4° and 1.9° when five frequencies(ten channels, 10.7, 18.7, 23.8, 36.5, 89 V/H GHz) are used. This method can effectively eliminate the influences of the soil moisture, roughness, atmosphere and various other factors. An analysis of the application of this method to the retrieval of land surface temperature from AMSR2 data indicates that the method is feasible. The accuracy is approximately 1.8° through a comparison between the retrieval results with ground measurement data from meteorological stations.MAO Kebiao ZUO Zhiyuan SHEN Xinyi XU Tongren GAO Chunyu LIU Guang 2018Chinese Geographical Science2018,28,1:3
17Silicon prepared by electro-reduction in molten salts as new energy materials显示文摘Silicon has a large impact on the energy supply and economy in the modern world. In industry, high purity silicon is firstly prepared by carbothermic reduction of silica with the produced raw silicon being further refined by a modified Siemens method. This process suffers from the disadvantages of high cost and contaminant release and emission. As an alternative, the molten salt electrolysis approach, particularly the FFC Cambridge Process(FFC: Fray-Farthing-Chen), could realize high purity silicon products with morphology-controllable nanostructures at low or mild temperatures(generally 650–900 ℃). In this article, we review the development, reaction mechanisms, and electrolysis conditions of silicon production by the FFC Cambridge Process. Applications of the silicon products from electrolysis in molten salts are also discussed in terms of energy applications, including using them as the photovoltaic element in solar cells and as the charge storage phase in the negative electrode(negatrode) of lithium ion batteries.Tingting Jiang Xinyi Xu George Z.Chen 2020Journal of Energy Chemistry2020,29,8:3
18A comprehensive analysis of the Bencao(herbal)small RNA Atlas reveals novel RNA therapeutics for treating human diseases显示文摘Cross-kingdom herbal mi RNA was first reported in 2012.Using a modified herbal extraction protocol,we obtained 73,677,287sequences by RNA-seq from 245 traditional Chinese Medicine(TCM),of which 20,758,257 were unique sequences.We constructed a Bencao(herbal)small RNA(s RNA)Atlas(http://gffzz4a3adbfa122d4a47h6pnucqcbvn5c60cc.ffgz.tsg.suse.edu.cn),annotated the sequences by sequence-based clustering,and created a nomenclature system for Bencao s RNAs.The profiles of 21,757 mi RNAs in the Atlas were highly consistent with those of plant mi RNAs in mi RBase.Using software tools,our results demonstrated that all human genes might be regulated by s RNAs from the Bencao s RNA Atlas,part of the predicted human target genes were experimentally validated,suggesting that Bencao s RNAs might be one of the main bioactive components of herbal medicines.We established roadmaps for oligonucleotide drugs development and optimization of TCM prescriptions.Moreover,the decoctosome,a lipo-nano particle consisting of 0.5%–2.5%of the decoction,demonstrated potent medical effects.We propose a Bencao(herbal)Index,including small-molecule compounds(SM),protein peptides(P),nucleic acid(N),non-nucleic and non-proteinogenic large-molecule compounds(LM)and elements from Mendeleev's periodic table(E),to quantitatively measure the medical effects of botanic medicine.The Bencao s RNA Atlas is a resource for developing gene-targeting oligonucleotide drugs and optimizing botanical medicine,and may provide potential remedies for the theory and practice of one medicine.Yinghao Cao Yexuan Lin Na Sun Xinyi Du Yixin Dong Song Mei Xingyu Deng Xiaobei Li Shaoting Guo Kegong Tang Jiaqi Liu Xiangyu Qiao Dandan Zhao Yuhao Qin Cong Zhang Tianyi Xin Xiaohu Shi Congzhao Zhou Tao Dong De-an Guo Benedikt MKessler Dong Xu Jingyuan Song Fengming Huang Xiaoyue Wang Chengyu Jiang 2023Science China(Life Sciences)2023,66,10:2
19METTL3-mediated m^(6)A RNA methylation regulates dorsal lingual epithelium homeostasis显示文摘The dorsal lingual epithelium,which is composed of taste buds and keratinocytes differentiated from K14^(+)basal cells,discriminates taste compounds and maintains the epithelial barrier.N6-methyladenosine(m^(6)A)is the most abundant mRNA modification in eukaryotic cells.How METTL3-mediated m^(6)A modification regulates K14^(+)basal cell fate during dorsal lingual epithelium formation and regeneration remains unclear.Here we show knockout of Mettl3 in K14^(+)cells reduced the taste buds and enhanced keratinocytes.Deletion of Mettl3 led to increased basal cell proliferation and decreased cell division in taste buds.Conditional Mettl3 knock-in mice showed little impact on taste buds or keratinization,but displayed increased proliferation of cells around taste buds in a protective manner during post-irradiation recovery.Mechanically,we revealed that the most frequent m^(6)A modifications were enriched in Hippo and Wnt signaling,and specific peaks were observed near the stop codons of Lats1 and FZD7.Our study elucidates that METTL3 is essential for taste bud formation and could promote the quantity recovery of taste bud after radiation.Qiuchan Xiong Caojie Liu Xin Zheng Xinyi Zhou Kexin Lei Xiaohan Zhang Qian Wang Weimin Lin Ruizhan Tong Ruoshi Xu Quan Yuan 2022International Journal of Oral Science2022,14,3:2
20Requirement and Development of Hydrogel Micromotors towards Biomedical Applications显示文摘With controllable size,biocompatibility,porosity,injectability,responsivity,diffusion time,reaction,separation,permeation,and release of molecular species,hydrogel microparticles achieve multiple advantages over bulk hydrogels for specific biomedical procedures.Moreover,so far studies mostly concentrate on local responses of hydrogels to chemical and/or external stimuli,which significantly limit the scope of their applications.Tetherless micromotors are autonomous microdevices capable of converting local chemical energy or the energy of external fields into motive forces for self-propelled or externally powered/controlled motion.If hydrogels can be integrated with micromotors,their applicability can be significantly extended and can lead to fully controllable responsive chemomechanical biomicromachines.However,to achieve these challenging goals,biocompatibility,biodegradability,and motive mechanisms of hydrogel micromotors need to be simultaneously integrated.This review summarizes recent achievements in the field of micromotors and hydrogels and proposes next steps required for the development of hydrogel micromotors,which become increasingly important for in vivo and in vitro bioapplications.Xinyi Lin Borui Xu Hong Zhu Jinrun Liu Alexander Solovev Yongfeng Mei 2020Research2020,,1:2
