1Coupling mechanism of roof and supporting wall in gob-side entry retaining in fully-mechanized mining with gangue backfilling显示文摘We analyzed the deformation characteristics of overlying stratum in backfilling with fully-mechanized and retaining roadways along the gob area coal mining technology, and established a mechanical model for the roof key stratum of retaining roadways along gob under the conditions of backfilling and fully- mechanized coal mining technology. Using Winkler elastic foundation theory, we analyzed a part of the key stratum under the action of elastic foundation coupling problem, and derived deflection analyt- ical expressions. Combined with specific conditions, we obtained the deflection curves for the roof key stratum of retaining roadways along gob under the conditions of backfilling and fully-mechanized coal mining technology. On this basis, we adopted the Coulomb's earth pressure theory to solve the problem of lateral pressure of the gangue filling area on the supporting wall beside the roadway and to provide the theoretical basis for reasonable selection of the distance between gangue concrete wall and roof and fur- ther discussion on the supporting stability of roadway.Ma Zhanguo Gong Peng Fan Jinquan Geng Minmin Zhang Guowei 2011Mining Science and Technology2011,21,6:15

3Urban expansion in China and its effect on cultivated land before and after initiating'Reform and Open Policy'显示文摘Urbanization in China has expanded at an unprecedented speed since the declaration of 'Reform and Open Policy'and presented many challenges. Unbalanced regional development, appearance of super megacities and concomitant problems,and conflicts between urbanization and cultivated land protection are three critical problems that Chinese urbanization has to face. To develop new plans for foreseeable future urbanization in China, it is critical to understand the evolving history of cities across China. This study maps urban expansion of 60 typical Chinese cities based on large amount of remote sensing data and the labor-intensive image interpretation method, in order to understand the history of urban expansion from the 1970 s to 2013.Results showed that area of cities expanded 5.23 times compared to their area in the 1970 s. Urban expansion in China accelerated three times(1988–1996, 1999–2006, and 2009–2011) and decelerated three times(1997–1998, 2007–2008, and 2012–2013) over the 40 years. The urban area of South China expanded most significantly 9.42 times, while the urban area in Northeast China expanded only 2.37 times. The disparity among different administrative ranks of cities was even greater than(3.81 times) the differences among different regions. Super megacities have been continuously expanding at a fast rate(8.60-fold), and have not shown obvious signs of slowing down. The proportion of cultivated land among the land sources for urban expansion decreased to a small extent in the 1990 s, but cultivated land continues to be the major land source for urban expansion. Effective future urbanization needs controlling the expansion scale of large cities and reasonably developing medium and small cities, as well as balancing regional development.ZHANG ZengXiang WEN QingKe LIU Fang ZHAO XiaoLi LIU Bin XU JinYong YI Ling HU ShunGuang WANG Xiao ZUO LiJun LI Na LI MinMin SHI LiFeng ZENG Tian JU HongRun 2016Science China Earth Sciences2016,59,10:12
4MXene-coated silk-derived carbon cloth toward flexible electrode for supercapacitor application显示文摘Flexible supercapacitors are promising energy storage devices in wearable smart electronics. Exploring cost-efficient electrodes with high capacitance would promote the wide-scale application of such capacitors. Herein, in order to explore a methodology for preparing low cost, flexible, tough, and up-scalable supercapacitor electrodes, silk textile is directly carbonized to make a conductive free-standing textile substrate. Through mildly baking the surfactant-free Ti_3C_2T_x flakes suspension loaded on the carbonized silk cloth, a uniform and adhesive coating consisting of nanometer-thick Ti_3C_2T_x flakes is well established on the conductive fabric support, forming a MXene-coated flexible textile electrode. The fabricated electrode exhibits a high areal capacitance of 362 m F/cm^2 with excellent cyclability and flexibility. Moreover,capacitance changes neglegibly under the bending deformation mode. This study elucidates the feasibility of using silk-derived carbon cloth from biomss for MXene-based flexible supercapacitor.Minmin Hu Tao Hu Renfei Cheng Jinxing Yang Cong Cui Chao Zhang Xiaohui Wang 2018Journal of Energy Chemistry2018,27,1:10
5LORELEI-LIKE GPI-ANCHORED PROTEINS 2/3 Regulate Pollen Tube Growth as Chaperones and Coreceptors for ANXUR/BUPS Receptor Kinases in Arabidopsis显示文摘Pollen tube growth is crucial for successful fertilization.In Arabidopsis thaliana,the ANXUR(ANX)/BUPS receptor kinase complex controls and maintains pollen tube growth in response to autocrine rapid alkalin-ization factor 4/19(RALF4/19)signaling;however,the molecular and cellular mechanisms underlying the ANX/BUPS-mediated regulation of pollen tube growth remain unclear.In this study,we found that pollen-specific LORELEI-like GPI-anchored proteins 2 and 3(LLG2/3)promote pollen tube growth in vitro and in vivo.LLG2/3 interacte with ANX/BUPS in a RALF4-concentration-dependent manner,suggesting that ANX/BUPS and LLG2/3 might form a receptor-coreceptor complex for perceiving RALF peptide signals.Disruption of the ANX/BUPS-LLG2/3 interaction led to the cytoplasmic retention of ANX1/2,in either llg2/3 knockdown mutants or in anx1/2 mutants lacking the J region,which mediates the ANX/BUPS-LLG2/3 interaction.Moreover,we found that RALF4 induced the production of reactive oxygen species(ROS),which stimulate pollen tube growth and reduce pollen burst rate.ROS levels are reduced in the pollen tubes of LLG2/3 RNAi lines,and application of exogenous H2O2 could partially rescue the defective pollen tube growth of LLG2/3 RNAi lines.Taken together,our study identifies LLG2/3 as novel regulatory components of pollen tube growth,and shows that they chaperone ANX/BUPS for secretion to the apical plasma membrane of pollen tube and act as coreceptors of ANX/BUPS in the acti-vation of ROS production for promoting pollen tube growth.Hanqian Feng Chen Liu Rong Fu Minmin Zhang Hui Li Lianping Shen Qiqi Wei Xiang Sun Lin Xu Bin Ni Chao Li 2019Molecular Plant2019,12,12:10
6Genomic landscape and genetic manipulation of the black soldier fly Hermetia illucens,a natural waste recycler显示文摘The black soldier fly(BSF),Hermetia illucens(Diptera:Stratiomyidae),is renowned for its bioconversion of organic waste into a sustainable source of animal feed.We report a high-quality genome of 1.1 Gb and a consensus set of 16,770 gene models for this beneficial species.Compared to those of other dipteran species,the BSF genome has undergone a substantial expansion in functional modules related to septic adaptation,including immune system factors,olfactory receptors,and cytochrome P450s.We further profiled midgut transcriptomes and associated microbiomes of BSF larvae fed with representative types of organic waste.We find that the pathways related to digestive system and fighting infection are commonly enriched and that Firmicutes bacteria dominate the microbial community in BSF across all diets.To extend its potential practical applications,we further developed an efficient CRISPR/Cas9-based gene editing approach and implemented this to yield flightless and enhanced feeding capacity phenotypes,both of which could expand BSF production capabilities.Our study provides valuable genomic and technical resources for optimizing BSF lines for industrialization.Shuai Zhan Gangqi Fang Minmin Cai Zongqing Kou Jun Xu Yanghui Cao Liang Bai Yixiang Zhang Yongmao Jiang Xingyu Luo Jian Xu Xia Xu Longyu Zheng Ziniu Yu Hong Yang Zhijian Zhang Sibao Wang Jeffery K.Tomberlin Jibin Zhang Yongping Huang 2020Cell Research2020,30,1:9
7Pollution characteristics, sources and lung cancer risk of atmospheric polycyclic aromatic hydrocarbons in a new urban district of Nanjing, China显示文摘This paper focused on the pollution characteristics,sources and lung cancer risk of atmospheric polycyclic aromatic hydrocarbons(PAHs) in a new urban district of Nanjing,China.Gaseous and aerosol PM_(2.5)(particulate matter with aerodynamic diameter smaller than2.5 urn) samples were collected in spring of 2015.Sixteen PAHs were extracted and analyzed after sampling.Firstly,arithmetic mean concentrations of PAHs and BaP_(eq)(benzo[a]pyrene equivalent) were calculated.The mean concentrations of PAHs were 29.26±14.13,18.14±5.37 and 48.47±16.03 ng/m^3 in gas phase,particle phase and both phases,respectively.The mean concentrations of BaP_(eq) were 0.87±0.51,2.71±2.17 and 4.06±2.31 ng/m^3 in gas phase,particle phase and both phases,respectively.Secondly,diagnostic ratios and principal component analysis were adopted to identify the sources of PAHs and the outcomes were the same:traffic exhaust was the predominant source followed by fuel combustion and industrial process.Finally,incremental lung cancer risk(ILCR) induced by whole year inhalation exposure to PAHs for population groups of different age and gender were estimated based on a Monte Carlo simulation.ILCR values caused by particle phase PAHs were greater than those caused by gas phase PAHs.ILCR values for adults were greater than those for other age groups.ILCR values caused by total(gas + particle) PAHs for diverse groups were all greater than the significant level(10~6),indicating high potential lung cancer risk.Sensitivity analysis results showed that cancer slope factor for BaP inhalation exposure and BaP_(eq) concentration had greater impact than body weight and inhalation rate on the ILCR.Tao Wang Zhonghuan Xia Minmin Wu Qianqian Zhang Shiqi Sun Jing Yin Yanchi Zhou Hao Yang 2017Journal of Environmental Sciences2017,29,5:7
8Adsorptive hemofiltration for sepsis management: expert recommendations based on the Asia Pacific experience显示文摘To the Editor:In sepsis,bacterial endotoxins play a central role by inducing a dysregulated and exaggerated release of inflammatory mediators and cytokines,often described as the“cytokine storm”or“cytokinemia.”[1]Both endotoxins and cytokines have been implicated in the development of organ dysfunction,including acute kidney injury(AKI).[2]Removing circulating endotoxins and excess cytokines from the circulation restores chemotactic gradients,localizing the immune response to the principal site of infection and re-establishing a regulated immune response.[1,3]Therefore,using hemofilters with enhanced endotoxin and cytokine adsorptive properties may bring about additional therapeutic benefits compared with conventional continuous renal replacement therapy(CRRT)filters.Ling Zhang Matthew Cove Binh G.Nguyen Nuttha Lumlertgul Kartik Ganesh Alfred Chan Giang T.H.Bui Chunwen Guo Junhua Li Songqiao Liu Mian Peng Kit W.Foong Jian Zhang Minmin Wang Jacques Goldstein Kai Harenski 2021Chinese Medical Journal2021,,18:6
9The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus.Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang 2016Science China(Life Sciences)2016,59,9:5
10Biochemistry of mammalian ferritins in the regulation of cellular iron homeostasis and oxidative responses显示文摘Ferritin,an iron-storage protein,regulates cellular iron metabolism and oxidative stress.The ferritin structure is characterized as a spherical cage,inside which large amounts of iron are deposited in a safe,compact and bioavailable form.All ferritins readily catalyze Fe(II)oxidation by peroxides at the ferroxidase center to prevent free Fe(II)from participating in oxygen free radical formation via Fenton chemistry.Thus,ferritin is generally recognized as a cytoprotective stratagem against intracellular oxidative damage.The expression of cytosolic ferritins is usually regulated by iron status and oxidative stress at both the transcriptional and post-transcriptional levels.The mechanism of ferritin-mediated iron recycling is far from clarified,though nuclear receptor co-activator 4(NCOA4)was recently identified as a cargo receptor for ferritin-based lysosomal degradation.Cytosolic ferritins are heteropolymers assembled by H-and L-chains in different proportions.The mitochondrial ferritins are homopolymers and distributed in restricted tissues.They play protective roles in mitochondria where heme-and Fe/S-enzymes are synthesized and high levels of ROS are produced.Genetic ferritin disorders are mainly related to the L-chain mutations,which generally cause severe movement diseases.This review is focused on the biochemistry and function of mammalian intracellular ferritin as the major iron-storage and anti-oxidation protein.Jianlin Zhang Xuehui Chen Juanji Hong Aifa Tang Yang Liu Ni Xie Guohui Nie Xiyun Yan Minmin Liang 2021Science China(Life Sciences)2021,64,3:5
11Numerical investigation on adiabatic film cooling effectiveness and heat transfer coefficient for effusion cooling over a transverse corrugated surface显示文摘Three-dimensional numerical computations are conducted to investigate the effects of the blowing ratio and corrugation geometry on the adiabatic film cooling effectiveness as well as the heat transfer coefficient over a transverse corrugated surface.It is noticeable that the adiabatic wall temperature on the wavy valley of the transverse corrugated surface is relatively lower than that on the wavy peak.Surface corrugation has a relatively obvious influence on the laterallyaveraged adiabatic film cooling effectiveness in the region where the effusion film layer is developed,but has little influence in the front region.Compared to a flat surface,the transverse corrugated surface produces a smaller adiabatic film cooling effectiveness and a higher heat transfer coefficient ratio.The effusion cooling difference between the flat and corrugated surfaces behaves more obviously under a small aspect ratio of the wavy corrugation.Qu Lihong Zhang Jingzhou Tan Xiaoming Wang Minmin 2017Chinese Journal of Aeronautics2017,30,2:5
12Carbon-based nanozymes for biomedical applications显示文摘Nanozymes are nanomaterials with enzyme-like properties that have attracted significant interest owing to their capability to address the limitations of traditional enzymes such as fragility,high cost,and impossible mass production.Over the past decade,a broad variety of nanomaterials have been found to mimic the enzyme-like activity by engineering the active centers of natural enzymes or developing multivalent elements within nanostructures.Carbon nanomaterials with well-defined electronic and geometric structures have served as favorable surrogates of traditional enzymes by mimicking the highly evolved catalytic center of natural enzymes.In particular,by combining the unique electronic,optical,thermal,and mechanical properties,carbon nanomaterials-based nanozymes can offer a variety of multifunctional platforms for biomedical applications.In this review,we will introduce the enzymatic characteristics and recent advances of carbon nanozymes,and summarize their significant applications in biomedicine.Hui Ding Bing Hu Bin Zhang Han Zhang Xiyun Yan Guohui Nie Minmin Liang 2021Nano Research2021,14,3:4
13Analysis of Aroma Volatile Compounds in Fuji Apple Using SPME with Different Fiber Coatings显示文摘The aroma volatile compounds in Fuji apple were isolated by solid-phase microextraction( SPME),and detected by gas chromatography-mass spectrometry( GC-MS). The results showed that the optimal retention time of the heating up of capillary columns was 5 min. Of the seven fibers used in this work,DVB/CAR/PDMS was found to be the most suitable to extract the aroma volatile compounds in Fuji apple. A total number of 43 volatile compounds were identified according to their retention time on capillary columns and their mass spectra,including eleven esters,ten alcohols,ten aldehydes,seven alkenes,two anhydrides,one ketone,one phenol and one ether. This detection method will provide a new foundation for analysis of volatile compounds in apple were identified.Jie LI Jicheng HAN Haie ZHANG Chaohong ZHANG Minmin LI Yu WANG 2020Agricultural Biotechnology2020,9,3:4
14Extraction of Basic Trends of Urban Expansion in China over Past 40 Years from Satellite Images显示文摘If urban sprawl is to be avoided in China in the next ten years, it is not only crucial to understand the overall history, current status, and future trends of urban expansion there, but also these differences, and this is presently lacking. In this study, remotely sensed images with approximately 30 m spatial resolution were used to quantitatively assess the spatial and temporal patterns of urban expansion of 60 Chinese cities(1973–2013). Urban-expansion-process curves of the cities studied were drawn using annual expansion area as an indicator. Curve similarity analysis generated four basic process modes of urban expansion in China. These included cities that: 1) peaked around 2004 and then decelerated; 2) peaked around 2010 and then decelerated; 3) showed sustained acceleration, and 4) showed continued deceleration. Four basic process modes represented cities under different levels of development stage. Geographic location was found to be the most related characteristic to urban expansion process. Regional development policies at the national level in each region also showed highly temporal consistency with fluctuation characteristics of urban expansion process. Urban characteristic such as population size and administrative level were not found to be significantly related to urban expansion-process modes. Understanding the basic process-mode categories well is extremely important for future regional-balance planning and development of macroeconomic policies.WEN Qingke ZHANG Zengxiang SHI Lifeng ZHAO Xiaoli LIU Fang XU Jinyong YI Ling LIU Bin WANG Xiao ZUO Lijun HU Shunguang LI Na LI Minmin 2016Chinese Geographical Science2016,26,2:4

16Tetrahydroisoquinolines as novel histone deacetylase inhibitors for treatment of cancer显示文摘Histone acetylation is a critical process in the regulation of chromatin structure and gene expression.Histone deacetylases(HDACs)remove the acetyl group,leading to chromatin condensation and transcriptional repression.HDAC inhibitors are considered a new class of anticancer agents and have been shown to alter gene transcription and exert antitumor effects.This paper describes our work on the structural determination and structure-activity relationship(SAR)optimization of tetrahydroisoquinoline compounds as HDAC inhibitors.These compounds were tested for their ability to inhibit HDAC 1,3,6 and for their ability to inhibit the proliferation of a panel of cancer cell lines.Among these,compound 82 showed the greatest inhibitory activity toward HDAC 1,3,6 and strongly inhibited growth of the cancer cell lines,with results clearly superior to those of the reference compound,vorinostat(SAHA).Compound 82 increased the acetylation of histones H3,H4 and tubulin in a concentration-dependent manner,suggesting that it is a broad inhibitor of HDACs.Danqi Chen Aijun Shen Guanghua Fang Hongchun Liu Minmin Zhang Shuai Tang Bing Xiong Lanping Ma Meiyu Geng Jingkang Shen 2016Acta Pharmaceutica Sinica B2016,6,1:4
17Microencapsulation of stearic acid with polymethylmethacrylate using iron(Ⅲ) chloride as photo-initiator for thermal energy storage显示文摘Aiming to identify the validity of fabricating microencapsulated phase change material(PCM) with polymethylmethacrylate(PMMA) by ultraviolet curing emulsion polymerization method using iron(III) chloride as photoinitiator,SA/PMMA microcapsules were prepared and various techniques were employed to determine the ignition mechanism,structural characteristics and thermal properties of the composite.The results shown that the microcapsules containing SA with maximum percentage of 52.20 wt% formed by radical mechanism and only physical interactions existed in the components both in the prepared process and subsequent use.The phase change temperatures and latent heats of the microencapsulated SA were measured as 55.3 °C and 102.1 J·g^(-1) for melting,and 48.8 °C and 102.8 J·g^(-1) for freezing,respectively.Thermal gravimetric analysis revealed that SA/PMMA has good thermal durability in working temperature range.The results of accelerated thermal cycling test are all shown that the SA/PMMA have excellent thermal reliability and chemical stability although they were subjected 1000 melting/freezing cycles.In summary,the comparable thermal storage ability and good thermal reliability facilitated SA/PMMA to be considered as a viable candidate for thermal energy storage.The successful fabrication of SA/PMMA capsules indicates that ferric chloride is a prominent candidate for synthesizing PMMA containing PCM composite.Ting Zhang Minmin Chen Yu Zhang Yi Wang 2017Chinese Journal of Chemical Engineering2017,25,10:3
18Tuning the luminous properties and optical thermometry of Cs_(2)SnCl_(6) phosphor microcrystals via Bi and Sb codoping显示文摘The toxicity and instability of lead halide perovskite seriously limit its commercial application in lighting,although it has high photoluminescence(PL)efficiency and adjustable emission.Here,lead-free bismuth(Bi)and antimony(Sb)codoped Cs_(2)SnCl_(6)(BSCSC)microcrystals(MCs)are prepared successfully by a solvothermal method.The PL spectrum is composed of dual emission bands with the peak at 485 and 650 nm,of which relative intensity can be tunable through the change of Bi and Sb feeding contents,respectively.Because of the phonon–electron interaction,the PL intensity is enhanced as the temperature rises within the range of 80–260 K.Then,the nonradiative transition is intensified until 380 K,which results in decrease in PL intensity.Simultaneously,combining with time-resolved PL,it is concluded that the emission peak at 485 nm is attributed to the[Bi_(Sn)+V_(Cl)]as the luminescent centers with the lifetime of hundreds of nanoseconds,and the emission peak at 650 nm is attributed to microsecond-timescale self-trapped excitons.The maximum values of relative sensitivity(S_(R))and absolute sensitivity(S_(A))values obtained are 3.82%K^(-1) and 5.11 ns·K^(-1),which for the first time to our knowledge demonstrate that BSCSC MCs can be novel luminescent materials for developing better optical thermometry.Whitelight-emitting diodes(WLEDs)are constructed using BSCSC MCs only combined with an LED chip,the Commission Internationale de L’Eclairage color coordinates of which are(0.30,0.37).It provides a novel scheme for the lighting field to realize WLEDs without adding additional commercial phosphors.SHUNFA GONG RUIRUI WU SEN YANG LIFANG WU MINMIN ZHANG QIUJU HAN WENZHI WU 2021Photonics Research2021,9,11:2
19Chiral polymer-based biointerface materials显示文摘Chirality is a unique phenomenon in nature. Chiral interactions play an important role in biological and physiological processes, which provides much inspiration for scientists to develop chiral materials. As a breakthrough from traditional materials, biointerface materials based on chiral polymers have attracted increasing interest over the past few years.
