| 2 | Thulium laser treatment for bladder cancer显示文摘Recent innovations in thulium laser techniques have allowed application in the treatment of bladder cancer.Laser en bloc resection of bladder cancer is a transurethral procedure that may offer an alternative to the conventional transurethral resection procedure.We conducted a review of basic thulium laser physics and laser en bloc resection procedures and summarized the current clinical literature with a focus on complications and outcomes.Literature evidence suggests that thulium laser techniques including smooth incision,tissue vaporization,and en bloc resection represent feasible,safe,and effective procedures in the treatment of bladder cancer.Moreover,these techniques allow improved specimen orientation and accurate determination of invasion depth,facilitating correct diagnosis,restaging,and reevaluation of the need for a second resection.Nonetheless,large-scale multicentre studies with longer follow-up are warranted for a robust assessment.The present review is meant as a quick reference for urologists. | Wei Wang Haitao Liu Shujie Xia | 2016 | Asian Journal of Urology2016，3，3： | 16 |
| 3 | Centimeter-scale-diameter Co-based bulk metallic glasses with fracture strength exceeding 5000 MPa显示文摘Co48-xFexCr15Mo14C15B6Er2 (x = 2.5 and 5) bulk metallic glasses (BMGs) with critical size (dc) up to 15 mm in diameter were synthesized by copper mold casting. Co43Fe5Cr15Mo14C15B6Er2 BMG has a wide supercooled liquid region (84 K) and ultrahigh fracture strength exceeding 5000 MPa,which is the highest value for reported metallic glasses with dc exceeding 1 cm. Furthermore,the Poisson ratio,Young modulus,shear modulus and bulk modulus of this alloy were evaluated to be 0.31,217 GPa,82 GPa and 214 GPa,respectively. The ideal configurational entropy of Co48-xFexCr15Mo14C15B6Er2 (x = 0 and 5) has been calculated. The introduction of the similar element Fe in the Fe-free Co-Cr-Mo-C-B-Er alloy will be beneficial to increasing the ideal config-urational entropy and depressing the critical cooling rate to achieve greater glass-forming ability. The combination of superior glass-forming ability and ultrahigh fracture strength makes the present Co48-xFexCr15Mo14C15B6Er2 (x = 2.5 and 5) BMGs promising candidates as advanced structural materials. | ZHANG Tao YANG Qin JI YunFei LI Ran PANG ShuJie WANG JianFeng XU Tao | 2011 | Chinese Science Bulletin2011，56，36： | 10 |
| 4 | The effect of nanohybrid materials on the pour-point and viscosity depressing of waxy crude oil显示文摘The pipeline transportation of waxy crude oil is a problem both at home and abroad.In this paper,a novel nanohybrid pour-point depressant (PPD) was used to decrease the pour point and viscosity of waxy crude oil.The pour point and apparent viscosity of waxy crude oil was decreased significantly upon addition of the nanohybrid PPD,and the long-term stability of the nanohybrid PPD was superior to that of a conventional ethylene-vinyl acetate copolymer PPD.Polarized optical microscopy and X-ray diffraction were used to study the effect of the nanohybrid PPD on the crystallization of crude oil.Addition of the nanohybrid PPD reduced the amount of wax crystals,prevented their aggregation,and reduced the temperature at which the crude oil started to crystallize.The significant effect of this nanohybrid PPD on the pour point and viscosity depressing of crude oil is of great importance for facilitating the safe,efficient and energy-minimized transportation of waxy crude oil. | WANG Feng ZHANG DongMin DING YanFen ZHANG LiXin YANG MingShu JIANG BaoLiang ZHANG ShiMin AI MuYang LIU GuangWen ZHI ShuJie HUO LianFeng OUYANG Xin LI Li | 2011 | Chinese Science Bulletin2011，56，1： | 9 |

| 6 | High-speed Rail and Urban Economic Growth in China after the Global Financial Crisis显示文摘High-speed rail(HSR)has been an important driver of China s economic expansion over the last decade.Using data of 285 prefecture-level cities over 2010-2014,this paper proposes an endogenous economic growth model to explain how and why HSR may have propelled China s economic growth by reducing the time-space between cities.The research results show that HSR has a potent effect on urban economic growth and regional convergence.Ceteris paribus,HSR appears to have accelerated economic growth by more than 0.6 percent and the pace of regional economic convergence by approximately 2 percent per annum over the data period.Our research findings have important policy implications for the sustainability of China s economic development,backed by HSR. | Shujie Yao Fan Zhang Feng Wang Jinghua Ou | 2019 | China & World Economy2019，27，2： | 7 |
| 7 | Effect of Ni addition on the glass-forming ability and soft-magnetic properties of FeNiBPNb metallic glasses显示文摘The effect of Ni addition on the glass-forming ability (GFA) and soft-magnetic properties of an (Fe1-xNix)75.5B14.5P7Nb3 (x=0-0.6) alloy system were investigated. We found that the addition of Ni was effective in allowing the alloy to approach a eutectic point as well as increasing the thermal stability of the supercooled liquid. By increasing the amount of Ni,the supercooled liquid region (ΔTx),the reduced glass transition temperature Trg (Tg/Tl) and the Y parameter [Tx/(Tg+Tl)] increased from 49 to 75 K,0.540 to 0.594 and 0.373 to 0.405,respectively. As a result,novel (Fe1-xNix)75.5B14.5P7Nb3 bulk metallic glass (BMG) rods with a maximum diameter of 1 mm were synthesized with a composition of x=0.5 and x=0.6 by copper mold casting. These metallic glasses have a moderate saturation magnetization of 0.37-1.20 T with good soft-magnetic properties,i.e. a low coercivity of 1.4-3.3 A/m and a high effective permeability of 13100-20900 at 1 kHz. The simultaneous achievement of a high GFA and good soft-magnetic properties for the FeNi-based alloy system is promising for the future development of BMGs. | WANG AnDing ZHANG MingXiao ZHANG JianHua MEN He SHEN BaoLong PANG ShuJie ZHANG Tao | 2011 | Chinese Science Bulletin2011，56，36： | 7 |
| 8 | Ultrasensitive and stable X-ray detection using zero-dimensional lead-free perovskites显示文摘Sensitive and reliable X-ray detectors are essential for medical radiography,industrial inspection and security screening.Lowering the radiation dose allows reduced health risks and increased frequency and fidelity of diagnostic technologies for earlier detection of disease and its recurrence.Three-dimensional(3 D)organic-inorganic hybrid lead halide perovskites are promising for direct X-ray detection-they show improved sensitivity compared to conventional X-ray detectors.However,their high and unstable dark current,caused by ion migration and high dark carrier concentration in the 3 D hybrid perovskites,limits their performance and long-term operation stability.Here we report ultrasensitive,stable X-ray detectors made using zero-dimensional(0 D)methylammonium bismuth iodide perovskite(MA3Bi2I9)single crystals.The 0 D crystal structure leads to a high activation energy(Ea)for ion migration(0.46 e V)and is also accompanied by a low dark carrier concentration(~10^6 cm^-3).The X-ray detectors exhibit sensitivity of 10,620μC Gy-1 air cm-2,a limit of detection(Lo D)of 0.62 nG yairs-1,and stable operation even under high applied biases;no deterioration in detection performance was observed following sensing of an integrated X-ray irradiation dose of^23,800 m Gyair,equivalent to>200,000 times the dose required for a single commercial X-ray chest radiograph.Regulating the ion migration channels and decreasing the dark carrier concentration in perovskites provide routes for stable and ultrasensitive X-ray detectors. | Xiaojia Zheng Wei Zhao Peng Wang Hairen Tan Makhsud I.Saidaminov Shujie Tie Ligao Chen Yufei Peng Jidong Long Wen-HuZhang | 2020 | Journal of Energy Chemistry2020，29，10： | 7 |
| 9 | Protective effects of human umbilical cord mesenchymal stem cell-derived conditioned medium on ovarian damage显示文摘Chemotherapeutic agents are extensively used to treat malignancies.However,chemotherapy-induced ovarian damage and reduced fertility are severe side effects.Recently,stem cell transplantation has been reported to be an effective strategy for premature ovarian insufficiency(POI)treatment,but safety can still be an issue in stem cell-based therapy.Here,we show the protective effects of human umbilical cord mesenchymal stem cell-derived conditioned medium(hUCMSC-CM)on a cisplatin(Cs)-induced ovarian injury model.hUCMSC-CM can relieve Cs-induced depletion of follicles and preserve fertility.In addition,hUCMSC-CM can decrease apoptosis of oocytes and granulosa cells induced by Cs.RNA sequencing analysis reveals the differentially expressed genes of ovaries after Cs and hUCMSC-CM treatments,including genes involved in cell apoptosis.Furthermore,we show that the granulocyte colony-stimulating factor(G-CSF)/phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)pathway plays an important role in protecting granulosa cells from Cs-induced apoptosis.Together,we confirm the protective effects of hUCMSC-CM on ovarian reserve and fertility in mice treated with Cs,highlighting the remarkable therapeutic effects of hUCMSC-CM. | Liming Hong Long Yan Zhimin Xin Jie Hao Wenjing Liu Shuyu Wang Shujie Liao Hongmei Wang Xiaokui Yang | 2020 | Journal of Molecular Cell Biology2020，12，5： | 7 |
| 10 | 5-Ethynyl-2′-deoxyuridine as a molecular probe of cell proliferation for high-content siRNA screening assay by “click” chemistry显示文摘Labelling and identification of proliferating cells is important for the study of physiological or pathological processes in high-content screening (HCS) assays. Here we describe ethynyl deoxyuridine (EdU) as a biomarker for the assessment of cell proliferation and clearly demonstrate the feasibility of the EdU-labelling method for use in HCS assays. EdU detection is highly robust, reproducible, technically simple, and well suited for automated segmentation, which provides an excellent al- ternative for setting up multiplexed HCS assays of siRNA, miRNA and small-molecule libraries. | CHEN MiaoJuan QU DeZhong CHI WeiLin WANG Wei REN XiaoShuai CONG ShuJie LIANG PeiZhou FENG ShiPeng ZHANG BiLiang | 2011 | Science China Chemistry2011，54，11： | 6 |
| 11 | Construction of an electronic physical map of Magnaporthe oryzae using genomic position-ready SSR markers显示文摘Magnaporthe oryzae is a model for plant pathogenic filamentous fungi. We have assembled a simple sequence repeat (SSR)-based physical map of the species, using in silico sequence data. A set of 120 SSR markers was developed from the genomic sequence of the reference isolate 70-15. These markers were readily amplified from the genomic DNA of other isolates, and high levels of allelic variation characterised the parental isolates of the two crosses tested. All the markers were locatable to one of the seven M. oryzae chromosomes. An SSR-based physical in silico map was constructed, and pre-existing SSR and RFLP loci were integrated into the map, along with 23 Avr (avirulence) genes and two other genes of importance to the plant/pathogen interaction. This map provides a platform for population genetics and functional genomics studies in the model pathogen, and even in other evolu- tionally related pathogens. | FENG ShuJie MA JunHong LIN Fei WANG Ling PAN QingHua | 2007 | Chinese Science Bulletin2007，52，24： | 5 |
| 12 | Genetic and physical mapping of AvrPi7, a novel avirulence gene of Magnaporthe oryzae using physical position-ready markers显示文摘Rice blast, caused by the fungal pathogen Magnaporthe oryzae, is one of the most devastating crop diseases worldwide. The avirulence gene corresponding to rice blast resistance gene Pi7 in field isolate CHL346 was inherited as a single gene, designated AvrPi7, in a segregating population consisting of 189 ascospore progenies derived from a cross between field isolates CHL346 and CHL42. In order to determine the chromosomal location of the AvrPi7 locus, a total of 121 simple sequence repeat (SSR) markers were developed based on the whole-genome sequence of reference isolate 70-15 of M. oryzae. Linkage analysis of the locus with these SSR markers showed that eight SSR markers on chromosome 1 were linked to the locus, among which the closest flanking markers MS1-9 and MS1-15 were 3.2 and 16.4 cM from the locus, respectively. For fine mapping, additional PCR-based makers including eight SSR markers and three candidate avirulence gene (CAG) markers were developed in the region flanking both markers. The AvrPi7 locus was genetically delimited within a 1.6-cM region flanked by markers MS1-21 and MS1-22, and co-segregated with the marker CAG2. To construct a physical map of the AvrPi7 locus, molecular markers linked to the Avr gene were mapped on the supercontigs of the ref-erence isolate 70-15 through bioinformation analysis (BIA). Consequently, the AvrPi7 locus was delim-ited to a 75-kb interval flanked by markers MS1-21 and MS1-22 based on the reference sequence. Merodiploids observed in this study are also discussed. | FENG ShuJie WANG Ling MA JunHong LIN Fei PAN QingHua | 2007 | Chinese Science Bulletin2007，52，7： | 5 |
| 13 | Mechanical Characteristics of Typical Plant Leaves显示文摘Plant leaf is a natural composite biomaterial, and its strength is closely related to the microstructure. In this paper, themechanical characteristics of eight species of plant leaves were investigated and analyzed. The ultimate strength of leaves andthe hardness of leaf surfaces were measured by using universal testing machine and nanoindenter tester, respectively. The tensilestrength of the parallel microstructure was investigated based on its cross-sectional mechanical model. The results of tensiontests indicate that the ultimate strength of a leaf is related to the material composition and structure. The coriaceous leavesusually exhibit higher tensile strength. For example, the Phyllostachys pubescens leaf can achieve the maximum ultimatestrength of 5.9091 N·mm-2. It is concluded from the results of hardness tests that material components of leaf surface caninfluence the surface hardness evidently. The leaf surface composed of more lignin and cellulose materials shows a highersurface hardness than that composed of more carbohydrates materials. | Shujie Wang, Luquan Ren, Yan Liu, Zhiwu Han, Yue Yang The Key Laboratory of Bionic Engineering (Ministry of Education, China), Jilin University, Changchun 130022, P.

| 14 | A qualitative study on nurses'reactions to inpatient suicide in a general hospital显示文摘Aims:To explore the impact of inpatient suicides on nurses working in front-line,the patterns of regulation and their needs for support.Methods:Data were collected through purposive sampling by conducting semi-structured and individual in-depth interviews in a tertiary referral hospital in China.Colaizzi's sevenstep phenomenological method was simultaneously used by two interviewers.Results:Reactions to inpatient suicides revealed three central themes:(1)inpatients were highly likely to commit suicide,(2)inpatient suicide was difficult to prevent,and(3)nurses lacked the necessary suicide prevention skills.Psychological responses mainly included shock and panic,self-accusation or guilt,sense of fear,and frustration.The impacts on practice were stress,excessive vigilance,and burnout.Avoidance and sharing of feelings played key roles in the regulation patterns of nurses.Conclusions:Nurses who experienced inpatient suicide became stressed.Effective interventions must be implemented to improve the coping mechanisms of nurses against the negative consequences of inpatient suicide.The findings of this study will allow administrators to gain insight into the impacts of inpatient suicides on nurses in general hospitals.Such information can be used to develop effective strategies and provide individual support and ongoing education.Consequently,nurses will acquire suicide prevention skills and help patients achieve swift recovery. | Shujie Wang Xiaoping Ding Deying Hu Keke Zhang Di Huang | 2016 | International Journal of Nursing Sciences2016，3，4： | 4 |
| 15 | TRIM35 mediates protection against influenza infection by activating TRAF3 and degrading viral PB2显示文摘Tripartite motif(TRIM)family proteins are important effectors of innate immunity against viral infections.Here we identified TRIM35 as a regulator of TRAF3 activation.Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon(IFN)in response to viral infection.777m35-deficient mice were more susceptible to influenza A virus(IAV)infection than were wild-type mice.TRIM35 promoted the RIG-Imediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1.IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3.TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2,thereby antagonizing its suppression of TRAF3 activation.Our in vitro and in vivo findings thus reveal novel roles of TRIM35,through catalyzing Lys63-or Lys48-linked polyubiquitination,in RIG-I antiviral immunity and mechanism of defense against IAV infection. | Nan Sun Li Jiang Miaomiao Ye Yihan Wang Guangwen Wang Xiaopeng Wan Yuhui Zhao Xia Wen Libin Liang Shujie Ma Liling Liu Zhigao Bu Hualan Chen Chengjun Li | 2020 | Protein & Cell2020，11，12： | 4 |
| 16 | Snowdrift effect on snow deposition:Insights from a comparison of a snow pit profile and meteorological observations in east Antarctica显示文摘A high-frequency and precise ultrasonic sounder was used to monitor precipitated/deposited and drift snow events over a 3-year period(17 January 2005 to 4 January 2008) at the Eagle automatic weather station site,inland Antarctica.Ion species and oxygen isotope ratios were also generated from a snow pit below the sensor.These accumulation and snowdrift events were used to examine the synchronism with seasonal variations of δ^(18)O and ion species,providing an opportunity to assess the snowdrift effect in typical Antarctic inland conditions.There were up to 1-year differences for this 3-year-long snow pit between the traditional dating method and ultrasonic records.This difference implies that in areas with low accumulation or high wind,the snowdrift effect can induce abnormal disturbances on snow deposition.The snowdrift effect should be seriously taken into account for high-resolution dating of ice cores and estimation of surface mass balance,especially when the morphology of most Antarctic inland areas is similar to that of the Eagle site. | DING MingHu ZHANG Tong XIAO CunDe LI ChuanJin JIN Bo BIAN LinGen WANG ShuJie ZHANG DongQi QIN DaHe | 2017 | Science China Earth Sciences2017，60，4： | 3 |
| 17 | Mineralogical characteristics of polymetallic sulfides from the Deyin-1 hydrothermal field near 15°S, southern Mid-Atlantic Ridge显示文摘A seafloor hydrothermal field, named Deyin-1 later, near 15°S southern Mid-Atlantic Ridge(SMAR) was newly found during the 22 nd cruise carried out by the China Ocean Mineral Resources Research & Development Association(COMRA). Sulfide samples were collected at three stations from the hydrothermal field during the26 th cruise in 2012. In this paper, mineralogical characteristics of the sulfides were analyzed with optical microscope, X-ray diffractometer, scanning electron microscope and electron microprobe to study the crystallization sequence of minerals and the process of hydrothermal mineralization. According to the difference of the ore-forming metal elements, the sulfide samples can be divided into three types:(1) the Ferich sulfide, which contains mainly pyrite and chalcopyrite;(2) the Fe-Cu-rich sulfide consisting predominantly of pyrite, chalcopyrite and isocubanite, with lesser amount of sphalerite, marmatite and pyrrhotine; and(3) the Fe-Zn-rich sulfide dominated by pyrite, sphalerite and marmatite, with variable amounts of chalcopyrite, isocubanite, pyrrhotine, marcasite, galena and gratonite. Mineral precipitations in these sulfides are in the sequence of chalcopyrite(isocubanite and possible coarse pyrite), fine pyrite,sphalerite(marmatite), galena, gratonite and then the minerals out of the dissolution. Two morphologically distinct generations(Py-I and Py-II) of pyrite are identified in each of the samples; inclusions of marmatite tend to exist in the coarse pyrite crystals(Py-I). Sphalerite in the Fe-Zn-rich sulfide is characterized by a'chalcopyrite disease' phenomenon. Mineral paragenetic relationships and a wide range of chemical compositions suggest that the environment of hydrothermal mineralization was largely changing. By comparison, the Fe-rich sulfide was formed in a relatively stable environment with a high temperature, but the conditions for the formation of the Fe-Cu-rich sulfide were variable. The Fe-Zn-rich sulfide was precipitated during the hydrothermal venting at relatively low temperature. | WANG Shujie LI Huaiming ZHAI Shikui YU Zenghui SHAO Zongze CAI Zongwei | 2017 | Acta Oceanologica Sinica2017，36，2： | 3 |
| 18 | ZbAGL11, a class D MADS-box transcription factor of Zanthoxylum bungeanum, is involved in sporophytic apomixis显示文摘Apomixis is a reproductive model that bypasses sexual reproduction,so it does not require the combination of paternal and maternal gametes but instead results in the production of offspring directly from maternal tissues.This reproductive mode results in the same genetic material in the mother and the offspring and has signi fi cant applications in agricultural breeding.Molecular and cytological methods were used to identify the reproductive type of Zanthoxylum bungeanum(ZB).Fluorescence detection of the ampli fi ed products of 12 pairs of polymorphic SSR primers showed consistent fl uorescence signals for mother and offspring,indicating that no trait separation occurred during reproduction.In addition,the cytological observation results showed differentiation of ZB embryos(2n)from nucellar cells(2n)to form inde fi nite embryonic primordia and then form adventitious embryos(2n),indicating that the apomictic type of ZB is sporophytic apomixis.The MADS-box transcription factor ZbAGLll was highly expressed during the critical period of nucellar embryo development in ZB.Unpollinated ZbAGLll-OE Arabidopsis produced fertile offspring and exhibited an apomictic phenotype.The overexpression of ZbAGL11 increased the callus induction rate of ZB tissue.In addition,the results of the yeast two-hybrid experiment showed that ZbAGL11 could interact with the ZbCYP450 and ZbCAD11 proteins.Our results demonstrate that ZbAGL11 can cause developmental disorders of Arabidopsis fl ower organs and result in apomixis-like phenotypes. | Xitong Fei Qianqian Shi Yichen Qi Shujie Wang Yu Lei Haichao Hu Yulin Liu Tuxi Yang Anzhi Wei | 2021 | Horticulture Research2021，8，1： | 3 |
| 19 | Development and application of wellbore heat transfer model considering variable mass flow显示文摘Dual-gradient drilling technology is being increasingly used in formations with narrow pressure margins.For dual-gradient drilling based on downhole separation,hollow spheres are separated into the annulus at the separator position,resulting in variable mass flow in the wellbore.Thus,existing heat transfer models are no longer suitable for describing wellbore temperature profiles in dual-gradient drilling.This study focused on developing a wellbore heat transfer model that fully considers separated hollow spheres entering the annulus,complex casing programs,and heat sources,for dual-gradient drilling based on downhole separation.The model was solved using an iterative method.Then,the accuracy of the model was verified using temperature data measured from two wells.Finally,the difference in the annular temperature distributions between dual-gradient drilling and conventional single-gradient drilling were investigated,as were the wellbore heat transfer characteristics for dual-gradient drilling.The following major conclusions were drawn:(1)for dualgradient drilling based on downhole separation,at the separator location,the annular fluid temperature does not decrease,but rather increase in the flow direction because of the inflow of hollow spheres;(2)a clear inflection point exists in the annular fluid temperature curve at the location where the separator would be;(3)the magnitude of the mutation of the temperature curve at the inflection point is considerably affected by the heat capacities of the hollow spheres and the pure drilling fluid;(4)under the same change in separation efficiency,distance between the bit and separator,flow rate,and thermal conductivity of formation,the variation range of the fluid temperature at the bottom hole is greater than that at the wellhead. | Jiangshuai Wang Jun Li Gonghui Liu Shujie Liu Meipeng Ren Kuidong Luo Shanxun Tao | 2021 | Underground Space2021，6，3： | 3 |
| 20 | Effect of xanthan gum on the quality of low sodium salted beef and property of myofibril proteins显示文摘The effects of xanthan gum (0 % and 0.3 %) on the quality of low sodium (2.0 %, 2.4 %, 2.8 %, 3.2 %, 3.6 % and 4.0 %) salted beef and property of myofibril proteins (MP) extracted from salted beef were researched. Changes in the salting absorptivity, cooking loss, shear force, color and sensory analysis showed that xanthan gum had a positive effect on the quality of salted beef with low salinity (2.0 %, 2.4 % and 2.8 %). MP of salted beef treated with xanthan gum had higher solubility, lower hydrogen bond than that without it (P < 0.05). The decrease of surface hydrophobicity and intrinsic fluorescence intensity indicated that the chromophore of protein was brought into a hydrophobic environment in the presence of xanthan gum. The electrophoresis showed that xanthan gum could improve the concentration of myosin heavy chain, paramyosin and actin after tumble-salting. The data suggested that salted beef and its MP treated with xanthan gum and 2.8 % salt (XS3) had the best properties. Together, xanthan gum could be considered as a sodium salt substitute for the development of low sodium meat products. | Zirui Zhao Shujie Wang Dayu Li Yajun Zhou | 2021 | Food Science and Human Wellness2021，10，1： | 3 |
