| 2 | Impact of gas pressure on particle feature in Fe-based amorphous alloy powders via gas atomization:Simulation and experiment显示文摘Gas atomization is now an important production technique for Fe-based amorphous alloy powders used in additive manufacturing,particularly selective laser melting,fabricating large-sized Fe-based bulk metallic glasses.Using the realizable k-εmodel and discrete phase model theory,the flow dynamics of the gas phase and gas-melt two-phase flow felds in the close-wake condition were investigated to establish the correlation between high gas pressure and powder particle characteristics.The locations of the recirculation zones and the shapes of Mach disks were analyzed in detail for the type of discrete-jet closed-coupled gas atomization nozzle.In the gas-phase flow feld,the vortexes,closed to the Mach disk,are found to be a new deceleration method.In the two-phase flow feld,the shape of Mach disk changes from“S”-shape to“Z”-shape under the impact of the droplet flow.As predicted by the wave model,with the elevation of gas pressure,the size of the particle is found to gradually decrease and its distribution becomes more concentrated.Simulation results were compliant with the Fe-based amorphous alloy powder preparation tests.This study deepens the understanding of the gas pressure impacting particle features via gas atomization,and contributes to technological applications. | Yutong Shi Weiyan Lu Wenhai Sun Suode Zhang Baijun Yang Jianqiang Wang | 2022 | Journal of Materials Science & Technology2022，，10： | 4 |

| 5 | Carboxyl-functionalized Nanocellulose Reinforced Nanocomposite Proton Exchange Membrane显示文摘Nanocellulose(NCC) was prepared through the acid hydrolysis of microcellulose(MCC) and was reacted with maleic anliydride to obtain carboxyl-functionized nanocellulose(MA-NCCs). The presence of .OH and .SO3H on the surface of rod-like MA-NCC was confirmed by Fourier transfonn infrared spectrometry(FTIR). Sulfonated poly(aryl ether ether ketone ketone)(Ph-SPEEKK) was synthesized with bis(4-fluorophenyl-methanone) and 2-phenylhydroquinone as monomer. MA-NCC/Ph-SPEEKK nanocomposite membranes with different MA-NCCs content were prepared, and their properties were characterized. Compared with Ph-SPEEKK, MA-NCC/Ph-SPEEKK nanocomposite membrane showed better mechanical and thermal properties and higher proton conductivity. The proton conductivity of the composite membrane with 4%(mass fraction) MA-NCCs under 80℃ was 0.095 S/cm. And its tensile strength reached 30.3 MPa, which was 21.2% higher than that of Ph-SPEEKK pure polymer membrane. | YANG Xue WEI Yingcong CHU Xuefeng ZHAO Qi YAN Wenling DONG Chenjun LIU Baijun SUN Zhaoyan HU Wei ZHANG Niaona | 2019 | Chemical Research in Chinese Universities2019，35，4： | 0 |

| 7 | Bioinformatic Analysis and Experimental Verification of QJHGD on Caerulein-induced Inflammatory Response in SAP Model Rats Based on TLR4/NF-κB/My D88 Pathway显示文摘[Objectives]To conduct bioinformatic analysis and experimental verification of Qingjie Huagong Decoction(QJHGD)on caerulein-induced inflammatory response in severe acute pancreatitis(SAP)model rats based on TLR4/NF-κB/MyD88 pathway.[Methods]The effective component groups and potential targets of QJHGD were collected by the network pharmacology method.A drug-component-target network was constructed.The GO and KEGG of targets were enriched and analyzed with the aid of Metascape database,and the target pathway related to SAP inflammation was screened.The SAP rat model was established by caerulein combined with lipopolysaccharide,and QJHGD was intragastrically administered.Pancreatic tissue was observed by HE staining.In addition,enzyme-linked immunosorbent assay and immunohistochemistry were used to verify the anti-inflammatory effect of QJHGD on SAP rats and its regulatory effect on TLR4/NF-κB/MyD88 target pathway.[Results]A total of 105 active components of QJHGD and 148 key targets of SAP were predicted and screened;KEGG was enriched in 320 different pathways including toll-like receptor and NF-κB classical pathways.Animal experiment verified that QJHGD reduced serum amylase,serum lipase activity,IL-6,TNF-αlevels in SAP rats;HE staining showed the effect of QJHGD on the pathological changes of pancreas,and QJHGD inhibited the positive expression of key proteins of TLR4,NF-κB and MyD88 in the inflammatory transduction pathway.[Conclusions]The mechanism of QJHGD improving pancreatic injury in SAP rats may be related to down-regulating the expression of key proteins in the TLR4/NF-κB/MyD88 pathway. | Baijun QIN Xiping TANG Xin YANG Xianzhong BU Wenhao GONG Yueqiao CHEN Guozhong CHEN | 2022 | Medicinal Plant2022，13，4： | 0 |
| 8 | Identifying the potential transcriptional regulatory network in Hirschsprung disease by integrated analysis of microarray datasets显示文摘Objective Hirschsprung disease(HSCR)is one of the common neurocristopathies in children,which is associated with at least 20 genes and involves a complex regulatory mechanism.Transcriptional regulatory network(TRN)has been commonly reported in regulating gene expression and enteric nervous system development but remains to be investigated in HSCR.This study aimed to identify the potential TRN implicated in the pathogenesis and diagnosis of HSCR.Methods Based on three microarray datasets from the Gene Expression Omnibus database,the multiMiR package was used to investigate the microRNA(miRNA)-target interactions,followed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses.Then,we collected transcription factors(TFs)from the TransmiR database to construct the TF-miRNA-mRNA regulatory network and used cytoHubba to identify the key modules.Finally,the receiver operating characteristic(ROC)curve was determined and the integrated diagnostic models were established based on machine learning by the support vector machine method.Results We identified 58 hub differentially expressed microRNAs(DEMis)and 16 differentially expressed mRNAs(DEMs).The robust target genes of DEMis and DEMs mainly enriched in several GO/KEGG terms,including neurogenesis,cell-substrate adhesion,PI3K-Akt,Ras/mitogen-activated protein kinase and Rho/ROCK signaling.Moreover,2 TFs(TP53and TWIST1),4 miRNAs(has-miR-107,has-miR-10b-5p,has-miR-659-3p,and has-miR-371a-5p),and 4 mRNAs(PIM3,CHUK,F2RL1,and CA1)were identified to construct the TF-miRNA-mRNA regulatory network.ROC analysis revealed a strong diagnostic value of the key TRN regulons(all area under the curve values were more than 0.8).Conclusion This study suggests a potential role of the TF-miRNA-mRNA network that can help enrich the connotation of HSCR pathogenesis and diagnosis and provide new horizons for treatment. | Wenyao Xu Hui Yu Dian Chen Weikang Pan Weili Yang Jing Miao Wanying Jia Baijun Zheng Yong Liu Xinlin Chen Ya Gao Donghao Tian | 2023 | World Journal of Pediatric Surgery2023，6，2： | 0 |
| 9 | Devitrification-induced an Ultrahigh Strength Al-based Composite Maintaining Ductility显示文摘A new Al-based composite consisting of submicron-sized α-Al matrix embedded with precipitated intermetallic phases was developed by controlling the devitrification process of an Al-Ni-Y-Co-La amorphous alloy.Such a homogeneous composite structure presented an ultrahigh strength of about 1.34 GPa and a large compressive plastic strain up to 22%.The unique mechanical properties during compression are mainly attributed to the dislocation slip deformation of ductile a-AI matrix and the shear-induced refinement of strengthening intermetallic phases. | Dong Kan Xiaopeng Li Baijun Yang Hongwang Yang Jianqiang Wang | 2015 | Journal of Materials Science & Technology2015，31，5： | 0 |
| 10 | Deformation behavior of Al-rich metallic glasses under nanoindentation显示文摘To clarify the deformation behavior of Al-rich metallic glasses(MGs), two kinds of Al-rich MGs(i.e. bulk and ribbon samples) with different frozen-in excess volume have been analyzed under nanoindentation.It was found that, with the decrease of frozen-in excess volume, the serration behavior becomes inconspicuous together with the increase of hardness. Further, shear transformation zones(STZs), related to the occurrence of shear banding, have been evaluated by different methods: the cooperative shearing model(CSM), the rate-jump method(RJM) and the dynamic-mechanical response(DMR). In contrast,the STZ volumes, calculated by the RJM, increase from 2.77 nm^3 in the bulk to 3.59 nm^3 in the ribbon,which are in good agreement with 2.60 nm^3 obtained from the icosahedral supercluster medium-range order structure model in Al-rich MGs. This result reflects that an intrinsic correlation exists between the formation of STZs and the medium-range orders(MROs). Moreover, the variation trend of the STZ volume was analyzed in terms of the frozen-in excess volume content. | Hui Guo Chuanbin Jiang Baijun Yang Jianqiang Wang | 2017 | Journal of Materials Science & Technology2017，33，11： | 0 |
| 11 | Indications,strategies,and development on prostate targeted biopsy:Report of the Panjiayuan Consensus Conference 2022显示文摘Prostate biopsy is the gold standard for diagnosing prostate cancer(PCa).Prostate targeted biopsy(TB)having a higher rate of detecting clinically significant PCa(csPCa)than traditional systematic biopsy(SB)is supported by high-quality evidence.However,the TB indications and strategies are controversial.The National Cancer Center/Cancer Hospital,Chinese Academy of Medical Sciences,invited a panel of recognized urology experts in PCa to address these topics at the Panjiayuan Consensus Conference 2022.The conference results on prostate TB are presented herein.The National Cancer Center/Cancer Hospital,Chinese Academy of Medical Sciences identified 10 key areas of prostate biopsy:(1)selection of imaging examination;(2)indications of TB;(3)transperineal and transrectal prostate biopsy;(4)TB pathways;(5)TB and SB;(6)three techniques of TB;(7)the number of TB cores needed for one lesion;(8)core number for SB;(9)free-hand TB;(10)future development of TB/prostate diagnosis.Thus,a panel of 25 recognized urologists and 2 radiologists from China were invited to attend this conference.The panel voted anonymously on 14 predetermined questions.Voting was based on the panelists'clinical practice and opinion,rather than high-level evidence.The voting outcomes were supported by the panel unequally,and details of the voting results were reported.The voting results can help clinicians to decide on biopsy timing and proper strategies,for which guidelines are sparse.We also focused on the future development of TB and SB,such as the combined pathway of TB and SB,techniques of TB,biopsy cores,free-hand TB,and prostate-specific membrane antigen positron emission tomography/computed tomography. | Gang Song Yajian Li Huimin Hou Yichen Wang Xuejuan Wang Shaoxi Niu Xiang Tu Hongliang Shen Zhien Zhou Yinbing Wang Ruiyi Yan Ning Xu Gejun Zhang Hailong Hao Shudong Zhang Ben Liu Bin Yang Baojun Wang Haifeng Wang Haifeng Huang Qian Zhang Baijun Dong Yonghong Li Jianbin Bi Weigang Yan Hongqian Guo Yuanjie Niu Guosheng Yang Ming Liu Qiang Wei Nianzeng Xing | 2023 | UroPrecision2023，1，1： | 0 |
| 12 | Thermally Conductive Study of Polyethylene/Al2O3 Composite Networks Cross-linked by Electron Beam Irradiation显示文摘The surface-modifled Al2O3 particles were introduced into polyethylene(PE)to enhance the thermal conductivity,and PE/Al2O3 cross-linked networks with improved thermal and mechanical properties were prepared through electron beam(EB)irradiation technology.The incorporation of reactive irradiation sensitizer was useful in fabricating a high degree of cross-linking(DC)PE networks under a low irradiation dose.In the PE sample containing 2%sensitizer,DC ca.67.1%could be obtained under 60 kGy(1 kGy=1000 J/kg).EB-irradiation greatly improved thetensile stress of PE-based samples,and the tensile stresses of the samples with 0.2—5%TMPTA(trimethylolpr pane triacrvlate)under 60 kGy were 24.61—27.77 MPa.All the EB-irradiated samples had higher Vicat softening temperatures than the samples without irradiation.After treatment at 120 kGy,the Vicat softening temperatures of PE-Al2O3-44/TMPTA-2 increased from 127℃to 130.4℃.SEM images revealed that PE-Al2O3-5O samples with increased amount of Al2O3 particles showed a conduction'pathway,'and thennal conductivity reached 0.67 W/(m·K).Thus,high-performance pipes were extruded,which could satisfy the static hydraulic blasting test and exhibit improved thennal conduction capability. | SHI Chengying YANG Jiayu LIU Yang WANG Yanmiao XU Wenge XU Yiquan HU Wei LIU Baijun | 2020 | Chemical Research in Chinese Universities2020，36，5： | 0 |
