1Synthesis of Porous NiO Nanocrystals with Controllable Surface Area and Their Application as Supercapacitor Electrodes显示文摘We report a facile way to grow various porous NiO nanostructures including nanoslices,nanoplates,and nanocolumns,which show a structure-dependence in their specific charge capacitances.The formation of controllable porosity is due to the dehydration and re-crystallization of β-Ni(OH)_(2) nanoplates synthesized by a hydrothermal process.Thermogravimetric analysis shows that the decomposition temperature of the β-Ni(OH)_(2) nanostructures is related to their morphology.In electrochemical tests,the porous NiO nanostructures show stable cycling performance with retention of specific capacitance over 1000 cycles.Interestingly,the formation of nanocolumns by the stacking of β-Ni(OH)_(2) nanoslices/plates favors the creation of small pores in the NiO nanocrystals obtained after annealing,and the surface area is over five times larger than that of NiO nanoslices and nanoplates.Consequently,the specific capacitance of the porous NiO nanocolumns(390 F/g)is significantly higher than that of the nanoslices(176 F/g)or nanoplates(285 F/g)at a discharge current of 5 A/g.This approach provides a clear illustration of the process-structure-property relationship in nanocrystal synthesis and potentially offers strategies to enhance the performance of supercapacitor electrodes.Xiaojun Zhang Wenhui Shi Jixin Zhu Weiyun Zhao Jan Ma Subodh Mhaisalkar Tuti Lim Maria Yanhui Yang Hua Zhang Huey Hoon Hng Qingyu Yan 2010Nano Research2010,3,9:24
2Tiller Bud Formation Regulators MOC1 and MOC3 Cooperatively Promote Tiller Bud Outgrowth by Activating F0N1 Expression in Rice显示文摘Tillering in rice is one of the most important agronomic traits.Rice tiller development can be divided into two main processes: the formation of the axillary bud and its subsequent outgrowth.Several genes critical for bud formation in rice have been identified by genetic studies;however,their molecular functions and relationships are still largely unknown.Here,we report that MONOCULM 1 (MOC1) and MONOCULM 3/ TILLERS ABSENT 1/STERILE AND REDUCED TILLERING 1 (MOC3/TAB1/SRT1),two vital regulators for tiller formation in rice,physically interact to regulate tiller bud outgrowth through upregulating the expression of FLORAL ORGAN NUMBER 1 (FON1),the homolog of CLAVATA1 in rice.We found that M0C3 is able to directly bind the promoter ofFONI and subsequently activate FON1 expression.MOC1 functions as a coactivator of MOC3,whereas it could not directly bind the FON1 promoter,and further activated FON1 expression in the presence of MOC3.Accordingly,FON1 is highly expressed at axillary meristems and shows remarkably decreased expression levels in mod and moc3 mutants.Loss-of-function mutants of FON1 exhibit normal bud formation but defective bud outgrowth and reduced tiller number.Collectively,these results shed light on a joint transcriptional regulatory mechanim by MOC1 and MOC3,and establish a new framework for the control of tiller bud formation and outgrowth.Gaoneng Shao Zefu Lu Jinsong Xiong Bing Wang Yanhui Jing Xiangbing Meng Guifu Liu Haiyan Ma Yan Liang Fan Chen Yonghong Wang Jiayang Li Hong Yu 2019Molecular Plant2019,12,8:15
3Variations in stem radii of Larix principis-rupprechtii to environmental factors at two slope locations in the Liupan Mountains,northwest China显示文摘Relationships between stem growth and climatic and edaphic factors,notably air temperatures and soil moisture for different slopes,are not completely understood.Stem radial variations were monitored at the bottom and top slope positions in a Larix principis-rupprechtii plantation during the 2017 and 2018 growing seasons.Total precipitation during the growing season in 2017 and 2018 was 566 mm and 728 mm,respectively.Stem contractions typically occurred after mid-morning followed by swelling in the late afternoon in both plots,reflecting the diurnal cycle of water uptake and loss.Trees at the two locations showed the same growth initiation(mid-May)because of the small differences in air and soil temperatures.There were no significant differences in cumulative stem radial growth between the bottom plot(1.57±0.34 mm)and the top plot(1.55±0.26 mm)in 2018.However,in 2017,the main growth period of the bottom plot ceased 17 days earlier than in the top plot,while cumulative seasonal growth of the bottom plot(1.08±0.25 mm)was significantly less than the top plot(1.54±0.43 mm).Maximum daily stem shrinkage was positively correlated with air and soil temperatures,solar radiation,vapor pressure deficits,and negatively correlated with volumetric soil moisture content.The maximum daily shrinkage reflected transpiration rates as affected by environmental factors.Daily radial stem increment was correlated with precipitation and volumetric soil moisture in both years,but with air temperatures only in 2017.The seasonal growth of L.principis-rupprechtii Mayr thus shows interannual dynamics,while precipitation constitutes a key driving factor.Jing Ma Jianbin Guo Yanhui Wang Zebin Liu Di Gao Liu Hong Ziyou Zhang 2021Journal of Forestry Research2021,32,2:6
4QTL mapping in A-genome diploid Asiatic cotton and their congruence analysis with AD-genome tetraploid cotton in genus Gossypium显示文摘Asiatic cotton(Gossypium arboreum L.) is an Old World cultivated cotton species.The sinense race was planted extensively in China.Due to the advances in spinning technology during the last century,the species was replaced by the New World allotetraploid cotton G.hirsutum L.Gossypium arboreum is still grown in India and Pakistan and also used as an elite in current cotton breeding programs.In addition,G.arboreum serves as a model for genomic research in Gossypium.In the present study,we generated an A-genome diploid cotton intraspecific genetic map including 264 SSR loci with three morphological markers mapped to 13 linkage groups.The map spans 2,508.71 cM with an average distance of 9.4 cM between adjacent loci.A population containing 176 F2:3 families was used to perform quantitative trait loci(QTL) mapping for 17 phenotypes using Multiple QTL Model(MQM) of MapQTL ver 5.0.Overall,108 QTLs were detected on 13 chromosomes.Thirty-one QTLs for yield and its components were detected in the F2 population.Forty-one QTLs for yield and its components were detected in the F2:3 families with a total of 43 QTLs for fiber qualities.Two QTLs for seed cotton weight/plant and lint index and three QTLs for seed index were consistently detected both in F2 and F2:3.Most QTLs for fiber qualities and yields were located at the same interval or neighboring intervals.These results indicated that the negative correlation between fiber qualities and yield traits may result from either pleiotropic effect of one gene or linkage effects of multiple closely linked genes.Xuexia Ma Yezhang Ding Baoliang Zhou Wangzhen Guo Yanhui Lv Xiefei Zhu Tianzhen Zhang 2008Journal of Genetics and Genomics2008,35,12:5
5Preparation of poly(glutamic acid) shielding micelles self-assembled from polylysine-b-polyphenylalanine for gene and drug codelivery显示文摘A novel amphiphilic cationic block copolymer polylysine-b-polyphenylalanine(PLL-b-PPhe)was synthesized and self-assembled into micelles in aqueous solution,then shielded with poly(glutamic acid)(marked as PG/PLL-b-PPhe)to codeliver gene and drug for combination cancer therapy.Here,doxorubicin(DOX)was selected to be loaded into PLL-b-PPhe micelles and the drug loading efficiency was 8.0%.The drug release studies revealed that the PLL-b-PPhe micelles were pH sensitive and the released DOX could reach to 53.0%,65.0%,72.0%at pH 7.4,6.8 and 5.0,respectively.In order to reduce positive charge and cytotoxicity of PLL-b-PPhe micelles,PG was used as shelding,simultaneously condensed with Bcl2 siRNA to form gene carrier system.Compared with PEI,PG/PLL-b-PPhe had excellent gene transfection efficiency,especially when the molar ratio of PLL to PPhe was 30:60 and the mixed mass ratio of PLL-b-PPhe to gene was 5:1.More importantly,DOX and Bcl2 siRNA gene codelivery system displayed remarkable cytotoxicity against B16 F10 cells.Confocal laser scanning microscopy(CLSM)and flow cytometry were used to characterize endocytosis of the codelivery system,and confirmed that both DOX and Bcl2 siRNA had been endocytosed into B16 F10 cells.The above results indicated that gene and drug codelivery was a promising strategy in future cancer therapy.Jing Ma Jingpeng Zhang Lin Chi Chong Liu Yanhui Li Huayu Tian 2020Chinese Chemical Letters2020,31,6:4
6Fargeted elimination of mutant mitochondria DNA in MELAS-iPSCs by mitoTALENs显示文摘Yi Yang Han Wu Xiangjin Kang Yanhui Liang Ting Lan Tianjie Li Tao Tan Jiangyun Peng Quanjun Zhang Geng An Yali Liu Qian Yu Zhenglai Ma Ying Lian Boon Seng Soh Qingfeng Chen Ping Liu Yaoyong Chen Xiaofang Sun Rong Li Xiumei Zhen Yang Yu Xiaoping Li Yong Fan 2018Protein & Cell2018,9,3:4
7A study on the changes of dynamic feature code when fixing bugs: towards the benefits and costs of Python dynamic features显示文摘Dynamic features in programming languages support the modification of the execution status at runtime, which is often considered helpful in rapid development and prototyping. However, it was also reported that some dynamic feature code tends to be change-prone or error-prone. We present the first study that analyzes the changes of dynamic feature code and the roles of dynamic features in bug-fix activities for the Python language. We used an AST-based differencing tool to capture fine-grained source code changes from 17926 bug-fix commits in 17 Python projects. Using this data, we conducted an empirical study on the changes of dynamic feature code when fixing bugs in Python. First, we investigated the characteristics of dynamic feature code changes, by comparing the changes between dynamic feature code and non-dynamic feature code when fixing bugs, and comparing dynamic feature changes between bug-fix and non-bugfix activities. Second, we explored 226 bug-fix commits to investigate the motivation and behaviors of dynamic feature changes when fixing bugs. The study results reveal that(1) the changes of dynamic feature code are significantly related to bug-fix activities rather than non-bugfix activities;(2) compared with non-dynamic feature code, dynamic feature code is inserted or updated more frequently when fixing bugs;(3) developers often insert dynamic feature code as type checks or attribute checks to fix type errors and attribute errors;(4) the misuse of dynamic features introduces bugs in dynamic feature code, and the bugs are often fixed by adding a check or adding an exception handling. As a benefit of this paper, we gain insights into the manner in which developers and researchers handle the changes of dynamic feature code when fixing bugs.Zhifei CHEN Wanwangying MA Wei LIN Lin CHEN Yanhui LI Baowen XU 2018Science China(Information Sciences)2018,61,1:4

9The calmodulin-dependent protein kinase II inhibitor KN-93 protects rat cerebral cortical neurons from N-methyl-D-aspartic acid-induced injury显示文摘In this study, primary cultured cerebral cortical neurons of Sprague-Dawley neonatal rats were treated with 0.25, 0.5, and 1.0 μM calmodulin-dependent protein kinase II inhibitor KN-93 after 50 μM N-methyl-D-aspartic acid-induced injury. Results showed that, compared with N-methyl-D-aspartic acid-induced injury neurons, the activity of cells markedly increased, apoptosis was significantly reduced, leakage of lactate dehydrogenase decreased, and intracellular Ca(2+) concentrations in neurons reduced after KN-93 treatment. The expression of caspase-3, phosphorylated calmodulin-dependent protein kinase II and total calmodulin-dependent protein kinase II protein decreased after KN-93 treatment. And the effect was apparent at a dose of 1.0 μM KN-93. Experimental findings suggest that KN-93 can induce a dose-dependent neuroprotective effect, and that the underlying mechanism may be related to the down-regulation of caspase-3 and calmodulin-dependent protein kinase II expression.Xuewen Liu Cui Ma Ruixian Xing Weiwei Zhang Buxian Tian Xidong Li Qiushi Li Yanhui Zhang 2013Neural Regeneration Research2013,8,2:3

11Ascorbate peroxidase 1 confers resistance to southern corn leaf blight in maize显示文摘Southern corn leaf blight (SCLB), caused by Bipolarismaydis, is one of the most devastatingdiseases affecting maize production. However,only one SLCB resistance gene, conferring partialresistance, is currently known, underscoring theimportance of isolating new SCLB resistancerelatedgenes. Here, we performed a comparativeproteomic analysis and identified 258 proteinsshowing differential abundance during the maizeresponse to B. maydis. These proteins included anascorbate peroxidase (Zea mays ascorbate peroxidase1 (ZmAPX1)) encoded by a gene locatedwithin the mapping interval of a previously identifiedquantitative trait locus associated with SCLBresistance. ZmAPX1 overexpression resulted inlower H_(2)O_(2) accumulation and enhanced resistanceagainst B. maydis. Jasmonic acid (JA)contents and transcript levels for JA biosynthesisand responsive genes increased in ZmAPX1-overexpressing plants infected with B. maydis,whereas Zmapx1 mutants showed the oppositeeffects. We further determined that low levels of H_(2)O_(2) are accompanied by an accumulation of JAthat enhances SCLB resistance. These resultsdemonstrate that ZmAPX1 positively regulatesSCLB resistance by decreasing H_(2)O_(2) accumulationand activating the JA-mediated defensesignaling pathway. This study identified ZmAPX1as a potentially useful gene for increasing SCLBresistance. Furthermore, the generated datamay be relevant for clarifying the functions ofplant APXs.Jinghua Zhang Xingmeng Jia Guan-Feng Wang Shijun Ma Shunxi Wang Qin Yang Xueyan Chen Yuqian Zhang Yajing Lyu Xiaoxu Wang Jiawei Shi Yangtao Zhao Yanhui Chen Liuji Wu 2022Journal of Integrative Plant Biology2022,64,6:2
12Geochemical characteristics of platinum-group elements in polymetallic nodules from the Northwest Pacific Ocean显示文摘Polymetallic nodules and cobalt (Co)-rich crusts are enriched in platinum-group elements (PGEs),especially platinum (Pt) and may be important sinks of PGEs.At present,little information is available on PGEs in polymetallic nodules,and their geochemical characteristics and the causes of PGEs enrichment are unclear.Here PGEs of polymetallic nodules from abyssal basin in the Marcus-Wake Seamount area of the Northwest Pacific Ocean are reported and compared with the published PGEs data of polymetallic nodules and Co-rich crusts in the Pacific.The total PGEs (ΣPGE) content of polymetallic nodules in study area is 258×10^–9) in average,markedly higher than that of Clarion-Clipperton Zone (CCZ) nodules (ΣPGE=127×10^–9) and lower than that of Co-rich crusts in the Marcus-Wake Seamount (ΣPGE=653×10^–9),similar to that of Co-rich crusts in the South China Sea(ΣPGE=252×10^~–9).The CI chondrite-normalized PGEs patterns in different regions of polymetallic nodules and cobalt-rich crusts are highly consistent,with all being characterized by positive Pt and negative Pd anomalies These results,together with those of previous studies,indicate that PGEs in polymetallic nodules and Co-rich crusts are mainly derived directly from seawater.Pt contents of polymetallic nodules from the study area are negatively correlated with water depth,and Pt/ΣPGE ratios in nodules there are also lower than those of the Corich crusts in the adjacent area,indicating that sedimentary water depth and oxygen fugacity of ambient seawater are the possible important controlling factors for Pt accumulation in crusts and nodules.Zhongrong Qiu Yanhui Dong Weilin Ma Weiyan Zhang Kehong Yang Hongqiao Zhao 2020Acta Oceanologica Sinica2020,39,8:2
13Geochemistry and age of seamounts in the West Pacific: mantle processes and petrogenetic implications显示文摘Research on seamounts provides some of the best constraints for understanding intraplate volcanism, and samples from seamounts reveal crucial evidence about the geochemical makeup of the oceanic mantle. There are still many seamounts in the West Pacific Seamount Province(WPSP) that have not been studied, meaning their ages and geochemistry remain unknown. A better understanding of these seamount trails and their evolutionary history, investigated with age and geochemistry data, will enable better understanding of the geological processes operating underneath the Pacific Ocean Plate. Here, new ^(40)Ar/^(39) Ar ages and trace element and Sr-Nd-Pb isotopic data for seven basalt rocks from four seamounts in the WPSP are provided. Chemically, these rocks are all Oceanic Island Alkali basalt(OIA type); analysis of olivine phenocrysts shows that the magmas experienced strong olivine fractionation and changed from olivine + plagioclase to olivine + plagioclase + clinopyroxene cotectic during their evolution. Rare earth element(REE) patterns and a spider diagram of the samples in this study show OIB(Ocean Island Basalt) like behavior. The range of ^(87)Sr/^(86) Sr values is from 0.704 60 to 0.706 24, the range of ^(206)Pb/^(204) Pb values is from 18.241 to 18.599, and the range of ^(143)Nd/^(144) Nd values is from 0.512 646 to 0.512 826; together, these values indicate magma sources ranging from EMI to EMII. Finally, new ^(40)Ar/^(39) Ar age data show that these seamounts formed at ~97 and ~106 Ma, indicating that some may have undergone the same formation processes as seamounts in the eastern part of the Magellan Seamount Trail, but other seamounts likely have different origins.Limei Tang Yanhui Dong Fengyou Chu Ling Chen Weilin Ma Yonggang Liu 2019Acta Oceanologica Sinica2019,38,1:2
14The entropy characters of point mutation显示文摘The biological diversity, which depends on the genetic material DNA, is the foundation for a species to survive and evolve. The entropy is the best measurement of biological diversity. Based on the sin-gle-parameter and the two-parameter models, here we established some differential equations about the point mutation of a DNA sequence with finite length, as well as some functions describing the processes of the variation in quantities of 4 kinds of bases (A, T, G and C) in the DNA sequence. At the molecular level, we discussed the entropy characteristics of point mutation. The results proved that a species maintained its entropy and evolved in the direction of the increasing biological diversity. In order to testify the theoretical results, we did a series of computer simulations of random point muta- tion in Matlab environment. The results were well consistent with the theoretical researches.MA GuoJi LIANG LiJing FAN YanHui WANG WenJuan DAI JiaQing YUAN ZhiFa 2008Chinese Science Bulletin2008,53,19:2
15Structure and properties of nanoporous FePt fabricated by dealloying a melt-spun Fe(60)Pt(20)B(20)alloy and subsequent annealing显示文摘A nanoporous FePt alloy has been fabricated by dealloying a melt-spun Fe(60)Pt(20)B(20)alloy composed of nanoscale amorphous and face-centered-cubic FePt(fcc-FePt)phases in H2 SO4 aqueous solution.The nanoporous alloy consists of single fcc-FePt phase with an Fe/Pt atomic ratio of about 55.3/44.7,and possesses a uniform interpenetrating ligament-channel structure with average ligament and pore sizes of 27 nm and 12 nm,respectively.The nanoporous fcc-FePt alloy shows soft magnetic characteristics with a saturation magnetization of 37.9 emu/g and better electrocatalytic activity for methanol oxidation than commercial Pt/C in acidic environment.The phase transformation from disordered fcc-Fe Pt into ordered face-centered-tetragonal FePt(L10-FePt)in the nanoporous alloy has been realized after annealing at823-943 K for 600 s.The volume fraction of the L10-FePt phase in the alloy increases with the rise of annealing temperature,which results in the enhancements of coercivity and saturation magnetization from 0.14 kOe and 38.5 emu/g to 8.42 kOe and 51.4 emu/g,respectively.The ligament size of the samples is increased after annealing.Dianguo Ma Yingmin Wang Yanhui Li Rie Y·Umetsu Shuli Ou Kunio Yubuta Wei Zhang 2020Journal of Materials Science & Technology2020,36,1:2
16The cancer-testis gene,MEIOB,sensitizes triple-negative breast cancer to PARP1 inhibitors by inducing homologous recombination deficiency显示文摘Objective:The newly defined cancer-testis(CT)gene,MEIOB,was previously found to play key roles in DNA double-strand break(DSB)repair.In this study,we aimed to investigate the effects and mechanisms of MEIOB in the carcinogenesis of triple-negative breast cancers(TNBCs).Methods:The Cancer Genome Atlas database was used to quantify the expression of MEIOB.Cox regression analysis was used to evaluate the association between MEIOB expression and the prognosis of human TNBC.The effects of MEIOB on cell proliferation and migration in TNBCs were also assessed in vitro.Patient-derived xenograft(PDX)models were used to assess the sensitivity of breast cancers with active MEIOB to PARP1 inhibitors.Results:We confirmed MEIOB as a CT gene whose expression was restricted to the testes and breast tumors,especially TNBCs.Its activation was significantly associated with poor survival in breast cancer patients[overall,hazard ratio(HR)=1.90(1.16–2.06);TNBCs:HR=7.05(1.16–41.80)].In addition,we found that MEIOB was oncogenic and significantly promoted the proliferation of TNBC cells.Further analysis showed that MEIOB participated in DSB repair in TNBCs.However,in contrast to its function in meiosis,it mediated homologous recombination deficiency(HRD)through the activation of poly ADP-ribose polymerase(PARP)1 by interacting with YBX1.Furthermore,activated MEIOB was shown to confer sensitivity to PARP inhibitors,which was confirmed in PDX models.Conclusions:MEIOB played an oncogenic role in TNBC through its involvement in HRD.In addition,dysregulation of MEIOB sensitized TNBC cells to PARP inhibitors,so MEIOB may be a therapeutic target of PARP1 inhibitors in TNBC.Yayun Gu Cheng Wang Rongxuan Zhu Jianshui Yang Wenwen Yuan Yanhui Zhu Yan Zhou Na Qin Hongbing Shen Hongxia Ma Hongxia Wang Xiaoan Liu Zhibin Hu 2021Cancer Biology & Medicine2021,18,1:2
17Effect of solution treatment on microstructures and mechanical properties of AISI 321 service显示文摘A detailed knowledge of changes in microstructures and mechanical properties that occur in AISI 321 stainless steels service before and after solution treatment is of great interest,since the ductility and toughness of AISI 321 stainless steels may change drastically after service for a long time.After solution treatment at 1050 ℃,the microstructures of AISI 321 stainless steels service for 80 000 h at 700 ℃ indicate that the content of sigma phase significantly decreased,the grains of austenite grew and the amount of twins together with the size increased with solution treatment time.The results of mechanical properties tests show that the impact toughness at room temperature was superior at solution treatment,and there was no obvious change in the impact toughness between different times of solution treatment at room temperature.Yanhui ZHAO Haitao MA Lai WANG Changhai SUN Chao GUO 2011Acta Metallurgica Sinica(English Letters)2011,24,3:2
18Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors.Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang 2019Asian Journal of Urology2019,6,1:2
