| 4 | Temporal changes in SSR allelic diversity of major rice cultivars in China显示文摘Forty simple sequence repeats (SSRs) were used to assess the changes of diversity in 310 major Chinese rice cultivars grown during the 1950s-1990s. Of the 40 SSR loci, 39 were polymorphic. A total of 221 alleles were detected with an average of 5.7 alleles per locus (Na). The Nei’s genetic diversity index (He) varied drastically among the loci (0.207 to 0.874, mean 0.625). Comparing the temporal changes in Na and He, the cultivars from the 1950s had more alleles and higher He scores than the cultivars from the other four decades Analysis of molecular variance (AMOVA) indicated that the genetic differentiation among the five decades was not significant in the whole set, but significant within indica and japonica. More changes among the decades were revealed in indica cultivars than in japonica cultivars. Some alleles had been lost in current rice cultivars in the 1990s, occurring more frequently in indica. These results suggest that more elite alien genetic resources should be explored to widen the genetic backgrounds of rice cultivars currently grown in China. | Xinghua Wei Xiaoping Yuan Hanyong Yu Yiping Wang Qun Xu Shengxiang Tang | 2009 | Journal of Genetics and Genomics2009，36，6： | 16 |
| 5 | Ubiquitination of Rheb governs growth factor-induced mTORC1 activation显示文摘Mechanistic target of rapamycin mTOR complex 1 (mTORC1)plays a key role in the integration of various environmental signals to regulate cell growth and metabolism,mTORC1 is recruited to the lysosome where it is activated by its interaction with GTP-bound Rheb GTPase.However,the regulatory mechanism of Rheb activity remains largely unknown.Here,we show that ubiquitination governs the nucleotide-bound status of Rheb.Lysosome-anchored E3 ligase RNF152 catalyzes Rheb ubiquitination and promotes its binding to the TSC complex.EGF enhances the deubiquitination of Rheb through AKT-dependent USP4 phosphorylation,leading to the release of Rheb from the TSC complex.Functionally,ubiquitination of Rheb is linked to mTORC1-mediated signaling and consequently regulates tumor growth.Thus,we propose a mechanistic model whereby Rheb-mediated mTORC1 activation is dictated by a dynamic opposing act between Rheb ubiquitination and deubiquitination that are catalyzed by RNF152 and USP4 respectively. | Lu Deng Lei Chen Linlin Zhao Yan Xu Xiaoping Peng Xinbo Wang Lin Ding Jiali Jin Hongqi Teng Yanming Wang Weijuan Pan Fei Yu Lujian Liao Li Li Xin Ge Ping Wang | 2019 | Cell Research2019，29，2： | 16 |
| 6 | Low-dose decitabine enhances the effect of PD-1 blockade in colorectal cancer with microsatellite stability by re-modulating the tumor microenvironment显示文摘PD-1 blockade has demonstrated impressive clinical outcomes in colorectal cancers that have high microsatellite instability.However,the therapeutic efficacy for patients with tumors with low microsatellite instability or stable microsatellites needs further improvement.Here,we have demonstrated that low-dose decitabine could increase the expression of immune-related genes such as major histocompatibility complex genes and cytokine-related genes as well as the number of lymphocytes at the tumor site in CT26 colorectal cancer-bearing mice.A more significant inhibition of tumor growth and a prolongation of survival were observed in the CT26 mouse model after treatment with a combination of PD-1 blockade and decitabine than in mice treated with decitabine or PD-1 blockade alone.The anti-tumor effect of the PD-1 blockade was enhanced by low-dose decitabine.The results of RNA sequencing and whole-genome bisulfite sequencing of decitabine-treated CT26 cells and tumor samples with microsatellite stability from the patient tumor-derived xenograft model have shown that many immune-related genes,including antigen-processing and antigen-presenting genes,were upregulated,whereas the promoter demethylation was downregulated after decitabine exposure.Therefore,decitabine-based tumor microenvironment re-modulation could improve the effect of the PD-1 blockade.The application of decitabine in PD-1 blockade-based immunotherapy may elicit more potent immune responses,which can provide clinical benefits to the colorectal cancer patients with low microsatellite instability or stable microsatellites. | Ganjun Yu Yanfeng Wu Wenying Wang Jia Xu Xiaoping Lv Xuetao Cao Tao Wan | 2019 | Cellular & Molecular Immunology2019，16，4： | 14 |

| 8 | Relationship between nutrients and plankton biomass in the turbidity maximum zone of the Pearl River Estuary显示文摘Nutrients,dissolved and particulate organic carbon and plankton(bacterio-,phyto-and zoo-)were compared in the turbidity maximum zone(TMZ) and adjacent areas(non-TMZ) in the Pearl River estuary.Our results showed that high levels of suspended substances had marked effect on dynamics of nutrients and plankton in the TMZ.Based on the cluster analysis of total suspended solids(TSS) concentrations,all stations were divided into two groups,TMZ with average TSS of 171 mg/L and non-TMZ of 45 mg/L.Suspended substances adsorbed PO^(3-)_4 and dissolved organic carbon,resulting in higher particulate phosphorus and organic carbon(POC)and lower PO^(3-)_4 and DOC in the TMZ,compared to the non-TMZ.However,suspended substances had limited effect on nitrogenous nutrients.Phytoplankton growth was light-limited due to high concentrations of suspended substances in the TMZ and a peak of phytoplankton abundance appeared in the non-TMZ.In contrast,the highest bacterial abundance occurred in the TMZ,which was likely partly responsible for low DOC levels.Two peaks of zooplankton abundance observed in the TMZ and non-TMZ in the Pearl River estuary were primarily supported by bacteria and phytoplankton,respectively.Our finding implied that high levels of suspended solids in the TMZ affect the trophic balance. | Zhen Shi Jie Xu Xiaoping Huang Xia Zhang Zhijian Jiang Feng Ye Ximei Liang | 2017 | Journal of Environmental Sciences2017，29，7： | 12 |
| 9 | Simulation of the piezoelectric high-speed on/off valve显示文摘The development trend and unsolved problems of the high-speed valve are given briefly, and the excellent characteristics and some key technologies of the piezoelectric high-speed on/off valve are introduced. An innovative high-speed on/off valve based on piezoelectric actuators is outlined, where the performance of the high frequency and high instant force is employed to kick off the poppet. The micro displacement amplification and temperature dependence of the piezoelectric actuator are solved. Furthermore, the mathematical model of the piezoelectric high-speed on/off valve is built and related simulation results are discussed.

| 10 | Holocene aeolian stratigraphic sequences in the eastern portion of the desert belt(sand seas and sandy lands) in northern China and their palaeoenvironmental implications显示文摘This paper presents the environmental history and its responses to palaeoclimatic changes since the start of the Holocene in the eastern portion of the desert belt(sand seas and sandy lands) in northern China by comparing the aeolian sandpalaeosol sequences and their palaeoclimatic proxies. The optically stimulated luminescence(OSL) ages of the aeolian sandpalaeosol sedimentary sequences and a series of palaeoenvironmental proxies show that:(1) The large-scale dune landscape currently in the Kubuqi Sand Sea was formed during the Holocene in general;and the palaeosol was generally developed during the period of 4–2 ka, indicating conditions favorable for vegetation growth, soil development, and organic carbon accumulation due to increased precipitation or effective moisture and weakened aeolian activities;the large-scale expansion of dunes in the recent 2 ka is closely linked to human activities. The variable discharge of the Yellow River with diversions for irrigation may have resulted in a more consistent supply of aeolian particles for dune field expansion.(2) The dune landscape of the Hunshandake Sandy Land was likely formed around 12 ka, and before this, the western part of the Hunshandake Sandy Land would have been covered by a single large lake;it was obviously wetter than today in the sandy land during the period of 9.6–3 ka and the palaeosols were developed at the same time. But the aeolian activities have not been completely dormant in this long-lasting wetter epoch;because the Holocene wetter period was likely time-transgressive across the region.(3) The palaeosol of the Hulunbuir Sandy Land began to develop as early as 14.5 ka, probably continuing until the last 2 ka. The palaeosol development of various dune fields in the eastern portion of the desert belt(sand seas and sandy lands) in northern China is spatially heterogeneous, and even the palaeosol development time in different locations within each sandy land is inconsistent. During the middle Holocene(especially the 7.5–3.5 ka), all the sandy lands were stabilized in general and the intensity of aeolian activities was significantly weakened. The number of palaeoenvironmental records in the eastern portion of the desert belt(sand seas and sandy lands) in northern China has increased rapidly in the past decade, but the amount of published data still does not match the vast extent of the dune fields. It does require much more in-depth palaeoenvironmental studies for a full understanding of the relationship between aeolian activities and climate change in northern China. | Xiaoping YANG Peng LIANG Deguo ZHANG Hongwei LI Patrick RIOUAL Xulong WANG Bing XU Zhibang MA Qianqian LIU Xiaozong REN Fangen HU Yuxin HE Gang RAO Ninghua CHEN | 2019 | Science China Earth Sciences2019，62，8： | 10 |
| 11 | MicroRNA in vivo precipitation identifies miR-151-3p as a computational unpredictable miRNA to target Stat3 and inhibits innate IL-6 production显示文摘MicroRNAs(miRNAs)function as important regulators in the immune response and inflammation.Several approaches have been reported to computationally predict miRNAs and their potential targets.However,there are still many miRNA–target interactions that are unpredictable by using the current computational algorithms.We established a miRNA in vivo precipitation method(miRIP)to identify unpredictable miRNAs with definite targets in these cells.Because Stat3 is a well-known transcription factor involved in innate immunity and inflammation,we utilized the miRIP method to identify miRNAs that bind Stat3 mRNA in macrophages.Among the captured miRNAs,miR-151-3p was confirmed to interact with Stat3 mRNA 3′-UTR and downregulate the Stat3 protein levels.LPS stimulation decreased miR-151-3p expression,thereby increasing IL-6 production.Therefore,we found that miR-151-3p inhibited LPS-induced IL-6 production by targeting Stat3.These data further confirmed miRIP as an efficient method to identify unpredictable miRNAs and explore miRNAs-mediated regulation in innate immunity and inflammation. | Xiang Liu Xiaoping Su Sheng Xu Huamin Wang Dan Han Jiangxue Li Mingyan Huang Xuetao Cao | 2018 | Cellular & Molecular Immunology2018，15，2： | 8 |
| 12 | Application of Active Flow Control Technique for Gust Load Alleviation显示文摘A new gust load alleviation technique is presented in this paper based on active flow control. Numerical studies are conducted to investigate the beneficial effects on the aerodynamic characteristics of the quasi 'Global Hawk' airfoil using arrays of jets during the gust process. Based on unsteady Navier-Stokes equations, the grid-velocity method is introduced to simulate the gust influence, and dynamic response in vertical gust flow perturbation is investigated for the airfoil as well. An unsteady surface transpiration boundary condition is enforced over a user specified portion of the airfoil’s surface to emulate the time dependent velocity boundary conditions. Firstly, after applying this method to simulate typical NACA0006 airfoil gust response to a step change in the angle of attack, it shows that the indicial responses of the airfoil make good agreement with the exact theoretical values and the calculated values in references. Furthermore, gust response characteristic for the quasi 'Global Hawk' airfoil is analyzed. Five kinds of flow control techniques are introduced as steady blowing, steady suction, unsteady blowing, unsteady suction and synthetic jets. The physical analysis of the influence on the effects of gust load alleviation is proposed to provide some guidelines for practice. Numerical results have indicated that active flow control technique,as a new technology of gust load alleviation, can affect and suppress the fluid disturbances caused by gust so as to achieve the purpose of gust load alleviation. | XU Xiaoping ZHU Xiaoping ZHOU Zhou FAN Ruijun | 2011 | Chinese Journal of Aeronautics2011，24，4： | 8 |

| 14 | Investigation of influence of coal properties on dense-phase pneumatic conveying at high pressure显示文摘Experiments of dense-phase pneumatic conveying of pulverized coal using nitrogen were carried out in a test facility at pressures of up to 3.7 MPa to study the effects of coal type, particle size and moisture content on flow characteristics. The Jenike shear test and scanning electron microscopy (SEM) were employed to provide a better understanding of effects of the material properties on flow characteristics. Two kinds of pulverized coals, Yanzhou and Datong, with similar particle size, moisture content and density, were used in the test. Pressure drop increases with increasing the particle size at similar solid-gas ratio, superficial velocity and pressure in the receiving hopper, and pressure drops through different test sections decrease firstly and then rise with increasing the conveying velocity for the same particle size, mass flow rate and pressure in the receiving hopper. The flowability of pulverized coal decreases with increasing the moisture content in the range from 3.24% to 8.18%. Unconfined yield strength (UYS) increases and flow function (FF) decreases with increasing the moisture content. Results of the shearing tests are consistent with the results of the conveying study. Pressure drops through different test sections are discussed and analyzed. | Cai Liang Xiaoxu Xie Pan Xu Xiaoping Chen Changsui Zhao Xin Wu | 2012 | Particuology2012，10，3： | 8 |

| 16 | Measurement of terrace deformation and crustal shortening of some renascent fold zones within Kalpin nappe structure显示文摘The Kalpin nappe structure is a strongest thrust and fold deformation belt in front of the Tianshan Mountains since the Cenozoic time. The tectonic deformation occurred in 5―6 striking Meso-zoic-Cenozoic fold zones, and some renascent folds formed on the recent alluvial-proluvial fans in front of the folded mountains. We used the total station to measure gully terraces along the longitudinal to-pographic profile in the renascent fold zones and collected samples from terrace deposits for age de-termination. Using the obtained formation time and shortening amount of the deformed terraces, we calculated the shortening rate of 4 renascent folds to be 0.1±0.03 mm/a, 0.12±0.04 mm/a, 0.59±0.18 mm/a, and 0.26±0.08 mm/a, respectively. The formation time of the renascent folds is some later than the major tectonic uplift event of the Qinghai-Tibet Plateau 0.14 Ma ago. It may be the long-distance effect of this tectonic event on the Tianshan piedmont fold belt. | YANG XiaoPing RAN YongKang CHENG JianWu CHEN LiChun XU XiWei | 2007 | Science China Earth Sciences2007，50，1： | 7 |
| 17 | Investigation of meso-failure behaviors of Jinping marble using SEM with bending loading system显示文摘In this study, the meso-failure mechanism and fracture surface of Jinping marble were investigated by means of scanning electron microscope(SEM) with bending loading system and laser-scanner equipment. The Yantang and Baishan marbles specimens from Jinping II hydropower station were used. Test results show that the fracture toughness and mechanical behaviors of Yantang marble were basically higher than those of Baishan marble. This is mainly due to the fact that Baishan marble contains a large percentage of dolomite and minor mica. Crack propagation path and fracture morphology indicated that the direction of tensile stress has a significant effect on the mechanical behaviors and fracture toughness of Baishan marble. For Yantang and Baishan marbles, a large number of microcracks around the main crack tip were observed when the direction of tensile stress was parallel to the bedding plane.Conversely, few microcracks occurred when the direction of tensile stress was perpendicular to the bedding plane. The presence of a large number of microcracks at the main crack tip decreased the global fracture toughness of marble. The results of three-point bending tests showed that the average bearing capacity of intact marble is 3.4 times the notched marble, but the ductility property of the defective marble after peak load is better than that of the intact marble. Hence, large deformation may be generated before failure of intact marbles at Jinping II hydropower station. The fractal dimension of fracture surface was also calculated by the cube covering method. Observational result showed that the largest fractal dimension of Yantang marble is captured when the direction of tensile stress is parallel to the bedding plane. However, the fractal dimension of fracture surface of Yantang and Baishan marbles with tensile stress vertical to the bedding plane is relatively small. The fractal dimension can also be used to characterize the roughness of fracture surface of rock materials. | Jianping Zuo Xu Wei Jianliang Pei Xiaoping Zhao | 2015 | Journal of Rock Mechanics and Geotechnical Engineering2015，7，5： | 6 |
| 18 | Cu Partitioning Behavior and Its Effect on Microstructure and Mechanical Properties of 0.12C-1.33Mn-0.55Cu Q&P Steel显示文摘Cu, as an austenitic stable element, is added to steel in order to suppress the adverse effects of high content of C and Mn on welding. Based on C partitioning, Cu and Mn partitioning can further improve the stability of retained austenite in the intercritical annealing process. A sample of low carbon steel containing Cu was treated by the intercritical annealing, then quenching process(I&Q). Subsequently, another sample was treated by the intercritical annealing, subsequent austenitizing, then quenching and partitioning process(I&Q&P). The effects of element partitioning behavior in intercritical region on the microstructure and mechanical properties of the steel were studied. The results showed that after the I&Q process ferrite and martensite could be obtained, with C, Cu and Mn enriched in the martensite. When intercritically heated at 800 ℃, Cu and Mn were partitioned from ferrite to austenite, which was enhanced gradually as the heating time was increased. This partitioning effect was the most obvious when the sample was heated at 800 ℃ for 40 min. At the early stage of α→γ transformation, the formation of γ was controlled by the partitioning of carbon, while at the later stage, it was mainly affected by the partitioning of Cu and Mn. After the I&Q&P process, the partitioning effect of Cu and Mn element could be retained. C was assembled in retained austenite during the quenching and partitioning process. The strength and elongation of I&Q&P steel was increased by 5 305 MPa% compared with that subjected to Q&P process. The volume fraction of retained autensite was increased from 8.5% to 11.2%. Hence, the content of retained austenite could be improved significantly by Mn and Cu partitioning, which increased the elongation of steel. | 陈连生 HU Baojia XU Jinghui 田亚强 ZHENG Xiaoping SONG Jinying XU Yong | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，5： | 6 |
| 19 | Cross-cultural adaption and psychometric properties of the Chinese version of the Diabetes Behavior Rating Scale: a pilot study显示文摘Self-care behavior plays a major role in diabetic management. However, in China, a satisfactory instrument has not yet been developed to evaluate the compliance of self-care behavior for young patients with type 1 diabetes mellitus(T1 DM). The Diabetes Behavior Rating Scale(DBRS) has a potential to be the first mature instrument. The purpose of this study is to cross-culturally adapt the DBRS, and preliminarily evaluate its psychometric properties. The instrument translation included translation, back translation and culture adaptation. Psychometric properties were assessed in a sample of 116 young patients with T1 DM adapting insulin injection therapy. The Chinese version of the DBRS was divided to four subscales. Cronbach's α for the total scale was 0.92. The mean inter-item and item-total correlations were 0.35 and 0.54 respectively. Test-retest reliability showed good temporal stability(r=0.81, P=0.001). Negative correlations were found between DBRS scores with the Diabetes Distress Scale scores(r=.0.32, P=0.003) and hemoglobin A1 c(HbA1 c) levels(r=.0.36, P=0.002). Higher DBRS scores correlated with better glycemic control. The Chinese insulin injection therapy version of the DBRS is well translated and culturally adapted. It shows good overall reliability and validity and appears to be a valuable tool for assessing the diabetic self-care behaviors for young patients with T1 DM. | Jing Zhu Jingjing Xu Yang Chen Yong Gu Li Ji Yufeng Zhou Min Zhu Hsiang-Ting Hsu Xiaoping Huang Cuiping Yuan Yun Shi Dan Yan Lili Xie Shuang Chen Tao Yang Wei He | 2018 | Science China(Life Sciences)2018，61，3： | 6 |
| 20 | Active blocks and strong seismic activity in North China region显示文摘The active North China block consists of three second-order blocks: Ordos, North China Plain, and East Shandong-Huanghai Sea blocks. Two active tectonic zones, the Anyang-Heze- Linyi and Tangshan-Cixian zones, exist in the active North China Plain block and have separated the active block into 3 third-order active blocks, Taihangshan, Hebei-Shandong, and Henan-Huai blocks. The 3 third-order active blocks are characterized by their entire motion and are clearly different in their Cenozoic structures and deep structures. The active boundary tectonic zones between the third-order active blocks are less than those between the first- and second-order active blocks in their movement strength, extent, and seismic activity. The density of M ≥ 6 earthquakes in the boundary zones between active blocks is higher than that within the blocks by 9-22 times in the North China region, up to one order of magnitude on average. M ≥ 7 earthquakes occurred basically in the boundary zones between active blocks. The difference is not occasional, but reflects the nature of intraplate movement and the characteristics of strong seismic activity and is the powerful evidence for hypothesis of active blocks. | HAN Zhujun (韩竹军) XU Jie (徐 杰) RAN Yongkang (冉勇康) CHEN Lichun (陈立春) YANG Xiaoping (杨晓平) | 2003 | Science China Earth Sciences2003，46，z2： | 6 |
