| 2 | The biological role of the CXCL12/CXCR4 axis in esophageal squamous cell carcinoma显示文摘Esophageal cancer is the eighth most common malignant tumor and the sixth leading cause of cancer-related death worldwide.Esophageal squamous cell carcinoma(ESCC)is the main histological type of esophageal cancer,and accounts for 90%of all cancer cases.Despite the progress made in surgery,chemotherapy,and radiotherapy,the mortality rate from esophageal cancer remains high,and the overall 5-year survival rate is less than 20%,even in developed countries.The C-X-C motif chemokine ligand 12(CXCL12)is a member of the CXC chemokine subgroup,which is widely expressed in a variety of tissues and cells.CXCL12 participates in the regulation of many physiological and pathological processes by binding to its specific receptor,C-X-C motif chemokine receptor type 4(CXCR4),where it causes embryonic development,immune response,and angiogenesis.In addition,increasing evidence indicates that the CXCL12/CXCR4 axis plays an important role in the biological processes of tumor cells.Studies have shown that CXCL12 and its receptor,CXCR4,are highly expressed in ESCC.This abnormal expression contributes to tumor proliferation,lymph node and distant metastases,and worsening prognosis.At present,antagonists and imaging agents against CXCL12 or CXCR4 have been developed to interfere with the malignant process and monitor metastasis of tumors.This article summarizes the structure,function,and regulatory mechanism of CXCL12/CXCR4 and its role in the malignancy of ESCC.Current results from preclinical research targeting CXCL12/CXCR4 are also summarized to provide a reference for the clinical diagnosis and treatment of ESCC. | Xianxian Wu Hongdian Zhang Zhilin Sui Yang Wang Zhentao Yu | 2021 | Cancer Biology & Medicine2021，18，2： | 9 |
| 3 | In situ scanning electron microscopy observation of deformation and fracture behavior of Ti-3Zr-2Sn-3Mo-25Nb alloy显示文摘The plastic deformation and fracture processes of Ti-3Zr-2Sn-3Mo-25Nb alloy for surgical implants were directly observed by in situ scanning electron microscopy(SEM).The effect of phase transformations on deformation-induced martensitic transformation accompanying the cyclic tensile fracture processes was investigated.The results reveal that the metastable alpha martensites(α″) promotes deformation-induced martensitic transformation to ductile fracture,whereas the omega(ω) and alpha(α) phases drastically prevent slip dislocation and deformation-induced martensitic transformation to brittle fracture. | Ma, Xiqun Yu, Zhentao Han, Yong Song, Xiping Sun, Qiaoyan | 2012 | Rare Metals2012，31，4： | 9 |
| 4 | Processing of a Novel Zn Alloy Micro-Tube for Biodegradable Vascular Stent Application显示文摘In recent years, zinc based alloys as a new biodegradable metal material aroused intensive interests.However, the processing of Zn alloys micro-tubes(named slender-diameter and thin-walled tubes) is very difficult due to their HCP crystal structure and unfavorable mechanical properties. This study aimed to develop a novel technique to produce micro-tube of Zn alloy with good performance for biodegradable vascular stent application. In the present work, a processing method that combined drilling, cold rolling and optimized drawing was proposed to produce the novel Zn–5Mg–1Fe(wt%) alloy microtubes. The micro-tube with outer diameter of 2.5 mm and thickness of 130 μm was fabricated by this method and its dimension errors are within 10 μm. The micro-tube exhibits a fine and homogeneous microstructure, and the ultimate tensile strength and ductility are more than 220 MPa and 20% respectively. In addition, the micro-tube and stents of Zn alloy exhibit superior in vitro corrosion and expansion performance. It could be concluded that the novel Zn alloy micro-tube fabricated by above method might be a promising candidate material for biodegradable stent. | Chang Wang Zhentao Yu Yajun Cui Yafeng Zhang Sen Yu Gongqi Qu Haibo Gong | 2016 | Journal of Materials Science & Technology2016，32，9： | 5 |
| 5 | Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety. | Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 4 |
| 6 | High-throughput development and applications of the compositional mechanical property map of the β titanium alloys显示文摘By a combination of the nanoindentation and electron probe microanalysis(EPMA)techniques,the traditional diffusion couple technique is extended to map the mechanical property of β-type Ti alloys over a wide composition range,which can be utilized to develop very versatile novel bio-Ti alloys for hard tissue re placements in arti ficial bones,joints,and dental implants.To create complete single-phase composition ranges of Ti-based bcc solid solution,12 types of bcc Ti-Nb-Zr-Mo/Ti-Nb-Zr-Ta quaternary diffusion couples were fabricated and annealed at 1273 K for 25 h.In this way,the composition-mechanical property relationships in the vast composition space of Ti-based alloys were established using EPMA and nanoindentation probes.Notably,the measured composition-dependent Young’s moduli,hardness,and elastic recovery as well as the derived ratio of hardness to Young’s modulus,and the ratio of the cube of hardness to the square of Young’s modulus,in the developed compositional mechanical property database,were visualized in a five-dimensional scatter plot.This enables an effective tool to screen the Ti-Nb-Zr-based alloys fororthopedic and dental applications according to different clinical requirements,and to rationalize the fundamental mechanical relationships in the rapid development of β-Ti alloys. | Jinfeng Ling Dandan Huang Kewu Bai Wei Li Zhentao Yu Weimin Chen | 2021 | Journal of Materials Science & Technology2021，，12： | 3 |
| 7 | Enhanced bioactivity and interfacial bonding strength of Ti3Zr2Sn3Mo25Nb alloy through graded porosity and surface bioactivation显示文摘The gradient porous Ti3Zr2Sn3Mo25Nb(TLM)alloy rods were fabricated through sintering the alloyed powder to a solid core.The porous sample was then modified by a Micro Arc Oxidation(MAO)treatment in an electrolyte containing calcium and phosphate,a hydrothermal treatment enabled secondary microporous hydroxyapatite(HA)coating,and a further bone morphogenetic protein-2(BMP-2)loading treatment through immersion and freeze-drying.The treatment led to an orderly secondary microporous coating containing HA nano-particles and evenly distributed BMP-2 in the porous coatings.As a result,osteoblasts could adhere and grow well on the coatings with a high cell adhesion rate and cell functional activity.The in-situ shear testing indicated that the interfacial strength had been enhanced significantly.Improvement of the bond formation and osseointegration with the titanium implant is attributed to increased surface area for the cell to attach,creating voids for the cell to grow in,and activating titanium surface by introducing bioactive ingredients such as HA and BMP-2. | Sen Yu Zhe Yu Dagang Guo Hui Zhu Minghua Zhang Jianye Han Zhentao Yu Yemin Cao Gui Wang | 2022 | Journal of Materials Science & Technology2022，，5： | 3 |

| 9 | Reactive Inorganic Vapor Deposition of Perovskite Oxynitride Films for Solar Energy Conversion显示文摘The synthesis of perovskite oxynitrides,which are promising photoanode candidates for solar energy conversion,is normally accomplished by high-temperature ammonolysis of oxides and carbonate precursors,thus making the deposition of their planar films onto conductive substrates challenging.Here,we proposed a facile strategy to prepare a series of perovskite oxynitride films.Taking SrTaO_(2)N as a prototype,we prepared SrTaO_(2)N films on Ta foils under NH_(3) flow by utilizing the vaporized SrCl_(2)/SrCO_(3) eutectic salt.The SrTaO_(2)N films exhibit solar water-splitting photocurrents of 3.0 mA cm^(-2) at 1.23 V vs.RHE(reversible hydrogen electrode),which increases by 270%compared to the highest photocurrent(1.1 mA cm^(-2) at 1.23 V vs.RHE)of SrTaO_(2)N reported in the literature.This strategy may also be applied to directly prepare a series of perovskite oxynitride films on conductive substrates such as ATaO_(2)N(A=Ca,Ba)and ANbO_(2)N(A=Sr,Ba). | Tao Fang Huiting Huang Jianyong Feng Yingfei Hu Qinfeng Qian Shicheng Yan Zhentao Yu Zhaosheng Li Zhigang Zou | 2019 | Research2019，，1： | 2 |

| 11 | Surpassing electrocatalytic limit of earth-abundant Fe^(4+)embedded in N-doped graphene for(photo)electrocatalytic water oxidation显示文摘Developing highly active,cost-effective,and environmental friendly oxygen evolution reaction(OER)electrocatalysts facilitates various(photo)electrochemical processes.In this work,Fe3N nanoparticles encapsulated into N-doped graphene nanoshells(Fe_(3)N@NG)as OER electrocatalysts in alkaline media were reported.Both the experimental and theoretical comparison between Fe_(3) N@NG and Fe_(3)N/NG,specifically including in situ Mossbauer analyses,demonstrated that the NG nanoshells improved interfacial electron transfer process from Fe_(3)N to NG to form high-valence Fe^(4+)ions(Fe^(4+)@NG),thus modifying electronic properties of the outer NG shells and subsequently electron transfer from oxygen intermediate to NG nanoshells for OER catalytic process.Meanwhile,the NG nanoshells also protected Fe-based cores from forming OER inactive and insulated Fe_(2)O_(3),leading to high OER stability.As a result,the as-formed Fe^(4+)@NG shows one of the highest electrocatalytic efficiency among reported Fe-based OER electrocatalysts,which can as well highly improve the photoelectrochemical water oxidation when used as the cocatalysts for the Fe_(2)O_(3) nanoarray photoanode. | Wenjia Xue Feng Cheng Menglu Li Wenjian Hu Congping Wu Bing Wang Kuowei Liao ZhenTao Yu Yingfang Yao Wenjun Luo Zhigang Zou | 2021 | Journal of Energy Chemistry2021，30，3： | 2 |

| 20 | Synthesis of alumina-nitrogen-doped carbon support for CoMo catalysts in hydrodesulfurization process显示文摘More stringent environmental legislation imposes severe requirements to reduce the sulfur content in diesel to ultra-low levels with high efficient catalysts.In this paper,a series of CoMo/NDC@alumina catalysts were synthesized by combination of the chemical vapor deposition of nitrogen-doped carbon(NDC)using 1,10-phenanthroline and co-impregnation of Mo and Co active components.The optimal catalyst with additive of 25%1,10-phenanthroline was screened by a series of property characterization and the hydrodesulfrization(HDS)active test.The amount of“CoMoS”active phase of the optimal CoMo/C3 catalyst increased 5.3%as compared with the CoMo/c-Al_(2)O_(3).The introduction of NDC improved the sulfidation degree of Mo by 21.8%as compared to the CoMo/c-Al_(2)O_(3) catalyst,which was beneficial to form more active sites.The HDS conversion of the NDC supported catalysts are higher than CoMo/c-Al_(2)O_(3) whether for the dibenzothiophene(DBT)or 4,6-dimethyl dibenzothiophene(4,6-DMDBT).Further hydroprocessing evaluation with Dagang diesel revealed that the CoMo/C3 catalyst possessed higher HDS property and the removal rate of DBTs in the diesel increased by 4%–11%as compared to the CoMo/c-Al_(2)O_(3) catalyst. | Zhentao Chen Yaxin Liu Jian Chen Yang Zhao Tao Jiang Fangyu Zhao Jiahuan Yu Haoxuan Yang Fan Yang Chunming Xu | 2022 | Chinese Journal of Chemical Engineering2022，35，1： | 1 |
