| 1 | AFLP analysis revealed differences in genetic diversity of four natural populations of Manila clam (Ruditapes philippinarum) in China显示文摘The amplified fragment length polymorphism (AFLP) technology was used to analyze the genetic diversities in four natural populations of Manila clam (Ruditapes philippinarum), distributed in four sea areas of China, i.e., the Bohai Sea, the Huanghai Sea, the East China Sea and the South China Sea. Two hundred and sixty-four AFLP loci were analysed in 195 individuals and revealed high levels of genetic diversity. The percentage of polymorphic loci ranged from 92.13% to 96.06% and the Shannon’s information index was from 0.256 8 to 0.275 6. By analyzing molecular variance (AMOVA), it was found that there were high levels of genetic differentiation between populations of Qingdao and the other three sea areas. Cluster analysis by Nei’s pairwise distances grouped specimens by geographical origin, except the population of Qingdao. A conclusion can be drawn that there are high genetic diversities in the four natural populations of Manila clam in China and some distinct differences existed among and between the four populations. The results also indicated that human cultivation activities will have great influence on the genetic structure of the population of Qingdao. | LIU Xiangquan BAO Zhenmin HU Jingjie WANG Shi ZHAN Aibin LIU Hui FANG Jianguang WANG Rucai | 2007 | Acta Oceanologica Sinica2007，26，1： | 18 |
| 2 | Microstructure characterization and corrosion behavior of Mg-Y-Zn alloys with different long period stacking ordered structures显示文摘Mg-Y-Zn alloys with long period stacking ordered(LPSO)structure have received much attention recently and exhibit great potential in applications such as automotive,aerospace and in bio-medical fields.This paper aimed to investigate the effect of different phase constitution of LPSO structures on corrosion rate of bio-medical Mg-Y-Zn alloys.The results showed that as-cast Mg98.5Y1Zn0.5 alloys containing only 18R structure exhibited the highest corrosion resistance with the corrosion rate of 2.78 mm/year.The precipitation of 14H lamellas within a-Mg grains during solid solution treatment introduced the crystallographic orientation corrosion by accelerating micro-galvanic corrosion.The increase of 18R/14H interfaces deteriorated the corrosion resistance,and the grain boundaries also suffered from severe electrochemical dissolution.This work suggested that Mg-Y-Zn alloys with single LPSO structure(either 18R or 14H)exhibited better corrosion resistance than alloys with co-existence 18R and I4H LPSO structures. | Lisha Wang Jinghua Jiang Huan Liu Bassiouny Saleh Aibin Ma | 2020 | Journal of Magnesium and Alloys2020，8，4： | 11 |
| 3 | Potential of multi-pass ECAP on improving the mechanical properties of a high-calcium-content Mg-Al-Ca-Mn alloy显示文摘In this study,the multi-pass equal channel angular pressing(ECAP)was employed on a high-calcium-content Mg-Al-Ca-Mn alloy to tailor its microstructure and mechanical properties.The obtained results showed that the network-shaped Mg2Ca and(Mg,Al)2Ca eutectic compounds in as-cast alloy were gradually crushed into ultra-fine particles after ECAP,which exhibited a bimodal particle size distribution and most aggregated at original grain boundaries.Dynamic recrystallization(DRX)of α-Mg occurred during hot deformation via a particle stimulated mechanism,and the almost complete DRX with an average grain size around 1.5μm was obtained after 12p-ECAP.Moreover,abundant nano-sized acicular and spherical precipitates were dynamically precipitated withinα-Mg grains during ECAP.Tensile test results indicated that the maximum strength and ductility were acquired for 12p-ECAP alloy with ultimate tensile strength of 372 MPa and fracture elongation of 8%.The enhanced strength of the alloy could be ascribed to fine DRX grains,ultra-fine Ca-containing particles and dynamically precipitated nano-precipitates,while the improved ductility was mainly due to the refined and homogeneous microstructure,and weak texture with high average Schmid factors. | He Huang Huan Liu Ce Wang Jiapeng Sun Jing Bai Feng Xue Jinghua Jiang Aibin Ma | 2019 | Journal of Magnesium and Alloys2019，7，4： | 10 |
| 4 | Improving toughness of a Mg_(2)Ca-containing Mg-Al-Ca-Mn alloy via refinement and uniform dispersion of Mg_(2)Ca particles显示文摘In this work,two wrought Mg-3.66Al-4.25Ca-0.43 Mn(wt%)alloys with different morphology and distribution of Mg_(2)Ca particles were fabricated by hot extrusion and multi-pass(32)equal channel angular pressing(ECAP).The as-extruded alloy exhibits a banded microstructure with alternately arranged Mg_(2)Ca particle bands,fine α-Mg dynamically recrystallized(DRX)grain bands,and coarse α-Mg deformed grain bands.The Mg_(2)Ca bands are composed of broken Mg_(2)Ca particles which are aggregated and aligned along extrusion direction.The microstructure of ECAP alloy contains complete α-Mg DRX grains and refined Mg_(2)Ca particles which are dispersedly distributed at grain boundaries.Tensile test results show that the as-extruded alloy possesses high ultimate tensile strength(UTS)of 420 MPa and poor fracture elongation of 7%,while the ECAP alloy exhibits improved toughness with UTS of 347 MPa and fraction elongation of 16%.The higher strength of as-extruded alloy is mainly ascribed to the contribution of coarse deformed grains with strong texture,and its poor toughness is resulted from the formation of Mg_(2)Ca bands within which microcracks could form and extend rapidly.On the contrary,the refined and dispersedly distributed Mg_(2)Ca particles are effective to retard crack initiation and impede crack propagation,thereby enhancing the toughness of ECAP alloy significantly. | Huan Liu Chao Sun Ce Wang Yuhua Li Jing Bai Feng Xue Aibin Ma Jinghua Jiang | 2020 | Journal of Materials Science & Technology2020，59，24： | 7 |

| 7 | Permeability Heterogeneity in a Fractured Sandstone-Mudstone Rock Mass in Xiaolangdi Dam Site,Central China显示文摘Heterogeneity of permeability in fractured media is a hot research topic in hydrogeology. Numerous approaches have been proposed to characterize heterogeneity in the last several decades. However,little attention has been paid to correlate permeability heterogeneity with geological information.In the present study,several causes of permeability heterogeneity,that is,lithology, tectonism,and depth,are identified.The unit absorption values(denoted asω),which are results obtained from the packer test,are employed to represent permeability.The variability of permeability in sandstone-mudstone is so significant that the value of unit absorptions span 3-4 orders of magnitude at any depth with several test sections.By declustering,it has been found that under a similar tectonic history,the means of permeability differ greatly at different formations as a result of different mudrock contents.It has also been found that in the same formation,permeability can be significantly increased as a result of faulting.The well-known phenomenon,the decrease in permeability with depth,is found to be caused by the fractures in the rock mass,and the relationship between permeability and depth can be established in the form of logω-logd.After subtracting the trend ofωwith absolute depth,the mean of the residual value at each relative depth can be well correlated with the distribution of mudstone. The methods proposed in this paper can be utilized to research in similar study areas. | JIANG Xiaowei WAN Li WANG Xusheng KANG Aibin HUANG Jun HUANG Guoxing | 2009 | Acta Geologica Sinica(English Edition)2009，83，5： | 4 |
| 8 | Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC. | Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 无 | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 4 |
| 9 | Correlation of Leaf and Root Senescence During Ripening in Dry Seeded and Transplanted Rice显示文摘Dry seeding is a resource-saving rice establishment method. With an equivalent yield, dry seeded flooded rice(DSR) has been considered as a replacement for traditional transplanted flooded rice(TFR). However, the differences in leaf and root senescence during grain filling between DSR and TFR were seldom identified. In this study, the root length, root tip number and leaf senescence of rice varieties Huanghuazhan and Yangliangyou 6 during ripening were compared between DSR and TFR. Results showed that top three leaves in DSR had the characteristics of relatively lower SPAD value, lower N content and premature leaf senescence. In addition, both the total root length and total root tip number of DSR were significantly lower than those of TFR. In conclusion, premature and quick leaf senescence was related with inadequate root length and root tip number during ripening, which might result from the deficiency of nitrogen supply in DSR. Techniques on improving leaf nitrogen status and delaying the leaf senescence during grain-filling in DSR should be developed in future researches. | LIU Hongyan WANG Weiqin HE Aibin NIE Lixiao | 2018 | Rice science2018，25，5： | 4 |
| 10 | 2022 Chinese expert consensus and guidelines on clinical management of toxicity in anti-CD19 chimeric antigen receptor T-cell therapy for B-cell non-Hodgkin lymphoma显示文摘Adoptive cellular immunotherapy with chimeric antigen receptor(CAR)T cells has emerged as a novel modality for treating relapsed and/or refractory B-cell non-Hodgkin lymphoma(B-NHL).With increasing approval of CAR T-cell products and advances in CAR T cell therapy,CAR T cells are expected to be used in a growing number of cases.However,CAR T-cell-associated toxicities can be severe or even fatal,thus compromising the survival benefit from this therapy.Standardizing and studying the clinical management of these toxicities are imperative.In contrast to other hematological malignancies,such as acute lymphoblastic leukemia and multiple myeloma,anti-CD19 CAR T-cell-associated toxicities in B-NHL have several distinctive features,most notably local cytokine-release syndrome(CRS).However,previously published guidelines have provided few specific recommendations for the grading and management of toxicities associated with CAR T-cell treatment for B-NHL.Consequently,we developed this consensus for the prevention,recognition,and management of these toxicities,on the basis of published literature regarding the management of anti-CD19 CAR T-cell-associated toxicities and the clinical experience of multiple Chinese institutions.This consensus refines a grading system and classification of CRS in B-NHL and corresponding measures for CRS management,and delineates comprehensive principles and exploratory recommendations for managing anti-CD19 CAR T-cell-associated toxicities in addition to CRS. | Ping Li Yang Liu Yun Liang Jian Bo Sujun Gao Yongxian Hu Yu Hu He Huang Xiaojun Huang Hongmei Jing Xiaoyan Ke Jianyong Li Yuhua Li Qifa Liu Peihua Lu Heng Mei Ting Niu Yongping Song Yuqin Song Liping Su Sanfang Tu Jianxiang Wang Depei Wu Zhao Wang Kailin Xu Zhitao Ying Qingming Yang Yajing Zhang Fengxia Shi Bin Zhang Huilai Zhang Xi Zhang Mingfeng Zhao Weili Zhao Xiangyu Zhao Liang Huang Jun Zhu Wenbin Qian Weidong Han Aibin Liang | 2023 | Cancer Biology & Medicine2023，20，2： | 3 |
| 11 | Rare earth elements and yttrium in ferromanganese deposits from the South China Sea:distribution,composition and resource considerations显示文摘Ferromanganese nodules and crusts contain relatively high concentration of rare earth elements(REE) and yttrium(REY),with a growing interest in exploitation as an alternative to land-based REY resources.On the basis of comprehensive geochemical approach,the abundance and distribution of REY in the ferromanganese nodules from the South China Sea are analyzed.The results indicate that the REY contents in ferromanganese deposits show a clear geographic regularity.Total REY contents range from 69.1×10^(–6) to 2 919.4×10^(–6),with an average value of 1 459.5×10^(–6).Especially,the enrichment rate of Ce content is high,accounting for almost 60% of the total REY.This REE enrichment is controlled mainly by the sorption of ferromanganese oxides and clay minerals in the nodules and crusts.Moreover,the total REY are higher in ferromanganese deposits of hydrogenous origin than of diagenetic origin.Finally,Light REE(LREE) and heavy REE(HREE) oxides of the ferromanganese deposits in the study area can be classified into four grades: non-enriched type,weakly enriched type,enriched type,and extremely enriched type.According to the classification criteria of rare earth resources,the Xisha and Zhongsha platform-central deep basin areas show a great potential for these rare earth metals. | ZHONG Yi CHEN Zhong GONZALEZ Francisco Javier ZHENG Xufeng LI Gang LUO Yun MO Aibin XU Antao WANG Shuhong | 2018 | Acta Oceanologica Sinica2018，37，7： | 3 |
| 12 | Fabrication of cellular Zn–Mg alloy foam by gas release reaction via powder metallurgical approach显示文摘By using CaCO_3 as the 'blowing agent', Zn–(10–50) wt% Mg alloy foams with close-pore structure were fabricated by the powder metallurgical route. The key of successful foaming is Mg addition and the proper sintering treatment, which lead to the formation of intermetallic compounds and can make the gas release reaction between Mg melt and CaCO_3 happen the during foaming process. | Donghui Yang Jianqing Chen Weiping Chen Lei Wang Hui Wang Jinghua Jiang Aibin Ma | 2017 | Journal of Materials Science & Technology2017，33，10： | 3 |
| 13 | Molecular identification of scallop planktonic larvae using species-specific microsatellites显示文摘The identification of scallop larvae is essential to understand the population structure and community dynamics and to assess the potential environmental impacts caused by scallop larvae released or escaped. However,the larvae identification by morphological characteristics is notoriously difficult,mainly due to the small size (usually being less than 150 μm) and vague morphological characteristics among different scallop species. A simple and accurate molecular method was developed to identify four economically farmed scallop species,the Zhikong scallop Chlamys farreri,the noble scallop C. nobilis,the bay scallop Argopecten irradians and the Yesso scallop Mizuhopecten yessoensis. The tests used the high degree of species-specific microsatellite markers,which was specified by transferability analyses,assessed by reference individuals and evaluated by BLAST searches. The sensitivity test indicated that the species-specific microsatellites were sensitive enough for the detection of 1%~2% larvae in mixed plankton samples. Larvae collected from scallop hatcheries and their effluents and from the artificially controlled crosses were well identified to the species/hybrid level. The results demonstrated that the one-step PCR-based assay was technically simple,inexpensive and robust in identification analyses,and also less sensitive to initial quality of template DNA extracted from the ethanol-preserved samples for several years. | ZHAN Aibin HU Xiaoli BAO Lisui LU Wei PENG Wei WANG Mingling HU Jingjie | 2008 | Acta Oceanologica Sinica2008，27，5： | 3 |

| 15 | Constitutive equation and hot deformation characteristic of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy with equiaxed microstructure显示文摘The hot deformation behavior of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy with equiaxed microstructure was characterized in the temperature range of 900~1060 ℃ and strain rate range of 10-3~10 s-1.The experimental results indicate that the plastic deformation behavior of the titanium alloys is rather sensitive to temperature and strain rate.In the α+β phase temperature region,all of the stress-strain curves exhibit different degrees of the flow softening after a peak stress.In the β phase temperature region,the titanium alloy shows a stress softening at high strain rates and a steady flow stress at low strain rates.On the basis of the peak stress data,the constitutive equations were constructed in the α+β phase temperature region and β phase temperature region,respectively.Activation energy parameters were calculated to be 344.923 kJ·mol-1 in the β phase temperature region and 628.3 kJ·mol-1 in the α+β phase temperature region.Microstructure of the compressed specimens in water-quenched conditions was found to be quite dependent on the conditions of deformation. | HUANG Lujun,GENG Lin,LI Aibin,WANG Guisong,and SHI Lei School of Materials Science and Engineering,Harbin Institute of Technology,Harbin 150001,China | 2007 | Rare Metals2007，26，S1： | 3 |
| 16 | The model of cytokine release syndrome in CAR T-cell treatment for B-cell non-Hodgkin lymphoma显示文摘Chimeric antigen receptor T(CAR T)cell therapy has demonstrated efficacy in the treatment of haematologic malignancies.However,the accompanying adverse events,the most common of which is cytokine release syndrome(CRS),substantially limit its wide application.Due to its unique physiological characteristics,CRS in CAR T-cell treatment for B-cell non-Hodgkin lymphoma(BNHL)may exhibit some special features.Although existing guidelines had greatly promoted the recognition and management of CRS,many recommendations are not fully applicable to B-NHL.Therefore,it is imperative to identify responses that are specific to CRS observed following CAR T treatment for B-NHL.Based on underlying biological processes and known pathophysiological mechanisms,we tentatively propose a new model to illustrate the occurrence and evolution of CAR T-cell-therapy-related CRS in BNHL.In this model,tumour burden and bone marrow suppression are considered determinants of CRS.Novel phenomena after CAR T-cell infusion(such as local inflammatory response)are further identified.The proposed model will help us better understand the basic biology of CRS and recognize and manage it more rationally. | Jianshu Wei Yang Liu Chunmeng Wang Yajing Zhang Chuan Tong Guanghai Dai Wei Wang John E.J.Rasko J.Joseph Melenhorst Wenbin Qian Aibin Liang Weidong Han | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |
| 17 | Development and Characterization of Microsatellite Markers for the Pacific Abalone (Haliotis discus) via EST Database Mining显示文摘The EST database of the Pacific abalone (Haliotis discus) was mined for developing microsatellite markers. A total of 1476 EST sequences were registered in GenBank when data mining was performed. Fifty sequences (approximately 3.4%) were found to contain one or more microsatellites. Based on the length and GC content of the flanking regions, cluster analysis and BLASTN, 13 microsatellite-containing ESTs were selected for PCR primer design. The results showed that 10 out of 13 primer pairs could amplify scorable PCR products and showed polymorphism. The number of alleles ranged from 2 to 13 and the values of Ho and He varied from 0.1222 to 0.8611 and 0.2449 to 0.9311, respectively. No significant linkage disequilibrium (LD) between any pairs of these loci was found, and 6 of 10 loci conformed to the Hardy-Weinberg equilibrium (HWE). These EST-SSRs are therefore potential tools for studies of intraspecies variation and hybrid identification. | ZHAN Aibin BAO Zhenmin WANG Mingling CHANG Dan YUAN Jian WANG Xiaolong HU Xiaoli LIANG Chengzhu HU Jingjie | 2008 | Journal of Ocean University of China2008，7，2： | 2 |

| 20 | Multi-technique integration separation frameworks after steam reforming for coal-based hydrogen generation显示文摘Coal-based H2 generation has abruptly increased in recent years.The PSA-VPSA-SC process is the matured and standard framework for H2 purification and CO_(2) capture in many existing plants,including normal and vacuum pressure swing adsorption units in series(PSA-VPSA),and shallow condensation unit(SC).However,this standard process is frequently subjected to low H2 recovery ratio and high purification cost.In this work,H2-selective and C02-selective membrane units,i.e.,HM and CO_(2) M,are attempted to support the standard process and ameliorate constraints.In the beginning,HM unit is arranged after VPSA to enhance H2 recovery from the decarbonized stream,i.e.,the PSA-VPSA-SC/HM process.As a result,H2 recovery ratio can be enhanced significantly from 83%to 98%.In the following,VPSA is replaced with CO_(2) M unit to reduce investment and operation cost,i.e.,the PSA-CO_(2) M-SC/HM process.Accordingly,the specific purification cost is diminished from 33.46 to 32.02 USD·(103 m^(3) H_(2))-1,saved by 4.3%,meanwhile the construction cost is falling back and just a little higher than that for the standard process.In the end,another CO_(2) M unit is launched before PSA,i.e.,the CO_(2) M-PSA-CO_(2) M-SC/HM process,which could unbundle CO_(2) enrichment partially from H2 purification,and then save more investment and operation cost.In comparison with the standard process,this ultimate retrofitted process can be superior in all the three crucial indices,i.e.,recovery ratio,investment,and specific purification cost.On the whole,coal-based H2 generation can be ameliorated significantly through high efficient H2-selective and CO_(2)-selective membrane units. | Xuehua Ruan Wenbo Huo Jiaming Wang Minggang Guo Wenji Zheng Yun Zou Aibin Huang Jianxiang Shou Gaohong He | 2021 | Chinese Journal of Chemical Engineering2021，34，7： | 1 |
