1Clinical significance of serum miR-21 in breast cancer compared with CA153 and CEA显示文摘Objective:MicroRNA-21(miR-21)has been shown to be a key regulator of carcinogenesis.There were few reports about the comparison of serum miR-21 with conventional tumor markers.This study aimed to explore the diagnostic value of circulating miR-21 as a tumor marker in breast cancer(BC)and compare it with CA153 and carcinoembryonic antigen(CEA).Methods:Circulating miR-16 and miR-21 were amplified and quantitatively detected by real-time PCR in 89 BC patients and 55 healthy controls.The levels of CA153 and CEA were measured through electrochemiluminescence assays.Then the sensitivity in diagnosis of BC was compared among miR-21,CA153 and CEA.Results:The level of serum miR-21 was significantly higher in BC patients than controls(P<0.001).The sensitivity and specificity of miR-21 were 87.6%and 87.3%,respectively,whereas the sensitivities of CEA and CA153 were only 22.47%and 15.73%.Conclusions:Compared with CEA and CA153,serum miR-21 has a higher sensitivity in diagnosis of BC.Although not correlated with the status of ER,PR and clinical stages,serum miR-21 may be a potential diagnostic indicator for BC,especially for the early stage.Jianjian Gao Qingyun Zhang Jianjun Xu Lijuan Guo Xuefeng Li 2013Chinese Journal of Cancer Research2013,25,6:36

5Acquisition of deleterious mutations duringpotato polyploidization显示文摘Potatoes(Solanum tuberosum L.) represent an important tuber crop, worldwide. During its prolonged clonal propagation, numerous deleterious mutations have accumulated in the potato genome,leading to severe inbreeding depression; however,the shaping of this mutation burden during polyploidization and improvement is largely unknown.Here, we sequenced 20 diploid landraces of the Stenotomum group, eight tetraploid landraces, and 20 tetraploid modern cultivars, to analyze variations in their deleterious mutations. We show that deleterious mutations accumulated rapidly during the polyploidization of tetraploid potatoes. This study provides a foundation for future potato improvement.Qun Lian Die Tang Zhiyan Bai Jianjian Qi Fei Lu Sanwen Huang Chunzhi Zhang 2019Journal of Integrative Plant Biology2019,61,1:8
6Effect of shrub-grass vegetation coverage and slope gradient on runoff and sediment yield under simulated rainfall显示文摘Evaluating the benefits of sediment and runoff reduction in different vegetation types is essential for studying the mechanisms of soil and water conservation on the Loess Plateau.The experiment was conducted in shrub-grass plots with nine levels of mixed vegetation coverage from 0%to 70%,three slopes(10,15,and 20)and two rainfall intensities(1.0 and 2.5 mm/min).The results showed that the vegetation coverage and slope gradient significantly affect runoff and sediment yield.Shrub-grass vegetation coverage had a significant effect on the runoff start-time,runoff flow velocity,runoff rate,and soil erosion rate on hillslopes.Mixed vegetation coverage could effectively delay the runoff starttime and decrease the runoff flow velocity.However,the effects of the slope gradient on runoff and sediment yield are opposite to those of vegetation coverage.Shrub-grass vegetation coverage could effectively increase runoff and sediment yield reduction benefits,while their benefits were affected by the rainfall intensity.At the 1.0 mm/min rainfall intensity,the reduction in the sediment production rate was greater than that under the 2.5 mm/min intensity.However,when the shrub-grass vegetation coverage exceeded 42%,the runoff reduction benefit was more obvious at higher rainfall intensities.The cumulative sediment yield increased with increasing cumulative runoff,and the rate of increase in the cumulative runoff was greater than that of the cumulative sediment yield with increasing of shrub-grass vegetation coverage.Moreover,there was a power function relationship between cumulative sediment yield and cumulative runoff yield(P<0.05).Our paper is expected to provide a good reference on the ecological environment and vegetation construction on the Loess Plateau.Dandan Han Jingcheng Deng Chaojun Gu Xingmin Mu Peng Gao Jianjian Gao 2021International Journal of Sediment Research2021,36,1:8

11The Influence of Regional SSTs on the Interdecadal Shift of the East Asian Summer Monsoon显示文摘自从 1970 年代末,东亚经历了重要 interdecadal 气候移动。这移动被全球 SST 的一个十的变化伴随。以前的研究建议了全球 SST 背景地位的十的移动在如此的气候的移动起了一个实质的作用。然而,不同地区性的 SST 的单个角色仍然保持不清楚。在这研究,我们用一个大气的一般发行量模型,的整体实验调查了这些角色 GFDL (地球物理的液体动力学实验室) AM2。二种整体被执行。第一是模型与观察 climatological SST 在被驾驶的一个控制整体。第二是模型在分开的海洋区域与观察 climatological SST 正 interdecadal SST 背景移动在被驾驶的一个试验性的整体。结果建议在热带的 SST 移动在 extratropics 比那些施加了更重要的影响,尽管后者平常地贡献移动。夏天 monsoonal 发行量系统的变化包括南方亚洲人高度,向西和平的副热带的高度,和降低水平的空气流动,被分析。结果证明与热带以外的 SST 导致的那些比较,热带 SST 导致的移动忍受更多的类似到观察并且到模拟,全球 SST 规定了。特别地,在热带太平洋的观察 SST 移动,而非印度洋,自从 1970 年代,显著地作出贡献到东方亚洲夏天季风的移动。FU Jianjian LI Shuanglin 2013Advances in Atmospheric Sciences2013,30,2:5
12The diffusive fluxes of inorganic nitrogen across the intertidal sediment-water interface of the Changjiang Estuary in China显示文摘Ammonium and nitrate concentrations were analyzed in near-bottom water and pore water collected from ten stations of the intertidal flat of the Changjiang Estuary during April, July, November and February. The magnitudes of the benthic exchange fluxes were determined on the basis of concentration gradients of ammonium and nitrate at the near-bottom water and interstitial water interface in combination with calculations of a modified Fick’s first law. Ammonium fluxes varied from-5.05 to 1.43 μg/(cm 2 ·d) and were greatly regulated by the production of ammonium in surface sediments, while nitrate fluxes ranged from-0.38 to 1.36 μg/(cm 2 ·d) and were dominated by nitrate concentrations in the tidal water. It was found that ammonium was mainly released from sediments into water columns at most of stations whereas nitrate was mostly diffused from overlying waters to intertidal sediments. In total, 823.75 t/a ammonium-N was passed from intertidal sediments to water while about 521.90 t/a nitrate-N was removed from overlying waters to intertidal sediments. This suggests that intertidal sediments had the significant influence on modulating inorganic nitrogen in the tidal water.HOU Lijun LIU Min XU Shiyuan LU Jianjian OU Dongni YU Jie 2006Acta Oceanologica Sinica2006,25,3:5

14MOF-derived molybdenum selenide on Ti_(3)C_(2)T_(x) with superior capacitive performance for lithium-ion capacitors显示文摘Two-dimensional Ti_(3)C_(2)T_(x) exhibits outstanding rate property and cycle performance in lithium-ion capacitors(LICs)due to its unique layered structure,excellent electronic conductivity,and high specific surface area.However,like graphene,Ti_(3)C_(2)T_(x) restacks during electrochemical cycling due to hydrogen bonding or van der Waals forces,leading to a decrease in the specific surface area and an increase in the diffusion distance of electrolyte ions between the interlayer of the material.Here,a transition metal selenide MoSe_(2) with a special three-stacked atomic layered structure,derived from metal-organic framework(MOF),is introduced into the Ti_(3)C_(2)T_(x) structure through a solvo-thermal method.The synergic effects of rapid Li+diffusion and pillaring effect from the MoSe_(2) and excellent conductivity from the Ti_(3)C_(2)T_(x) sheets endow the material with excellent electrochemical reaction kinetics and capacity.The composite Ti_(3)C_(2)T_(x)@MoSe_(2) material exhibits a high capacity over 300 mAh·g^(-1) at 150 mA·g^(-1) and excellent rate property with a specific capacity of 150 mAh·g^(-1) at 1500 mA·g^(-1).Addition-ally,the material shows a superior capacitive contribution of 86.0%at 2.0 mV·s^(-1) due to the fast electrochemical reactions.A Ti_(3)C_(2)T_(x)@MoSe_(2)//AC LIC device is also fabricated and exhibits stable cycle performance.Jianjian Zhong Lu Qin Jianling Li Zhe Yang Kai Yang Mingjie Zhang 2022International Journal of Minerals,Metallurgy and Materials2022,29,5:4
15Trans-regional transmission of large-scale hydropower: problems and solutions in receiving power grid显示文摘Large-capacity hydropower transmission from southwestern China to load centers via ultra-high voltage direct current(UHVDC) or ultra-high voltage alternating current(UHVAC) transmission lines is an important measure of the accommodation of large-scale hydropower in China. The East China Grid(ECG) is the main hydropower receiver of the west–east power transmission channel in China. Moreover, it has been subject to a rapidly increasing rate of hydropower integration over the past decade. Currently, large-scale outer hydropower is one of the primary ECG power sources. However, the integration of rapidly increasing outer hydropower into the power grid is subject to a series of severe drawbacks. Therefore, this study considered the load demands and hydropower transmission characteristics for the analysis of several major problems and the determination of appropriate solutions. The power supply-demand balance problem, hydropower transmission schedule problem, and peakshaving problem were considered in this study. Correspondingly, three solutions are suggested in this paper, which include coordination between the outer hydropower and local power sources, an inter-provincial power complementary operation, and the introduction of a market mechanism. The findings of this study can serve as a basis to ensure that the ECG effectively receives an increased amount of outer hydropower in the future.Jianyu Lu Jianjian Shen Chengguo Su Qianqian Shen 2019Global Energy Interconnection2019,2,4:4
16Seasonal dependency of controlling factors on the phytoplankton production in Taihu Lake, China显示文摘In this study, 44 profiles of gross primary productivity(GPP) and sunlight, along with water temperature, Chlorophyll-a(Chla) and nutrients, were observed in Meiliang Bay of Taihu Lake, China, in the spring, summer, and fall seasons. Effects of water temperature, light,and nutrient concentration were examined in relation to the GPP-unit-Chla(GPP of algae per Chla). The results showed that the optimum temperature for the GPP of phytoplankton was 27.9°C, the optimal PNA-unit-Chla(photon number absorbed by phytoplankton per Chla) was 0.25(mol), and the HSCN-unit-Chla and HSCP-unit-Chla(half-saturation constants of nitrogen and phosphorus of algae per Chla) were 0.005(mg/L) and 0.0004(mg/L), respectively. The seasonal dependency of the effect of different factors on the GPP was analyzed. Compared with temperature and nutrients, light was found to be the most important factor affecting the GPP during the three seasons. The effect of temperature and nutrients on the GPP of phytoplankton has obvious seasonal change. In spring, temperature was the secondary factor affecting the GPP of phytoplankton, and the effect of nutrients may be negligible in the eutrophic lake on account of temperature limit, which showed that the GPP of algae was only affected by the physical process. In summer and fall, temperature didn't affect the GPP of algae, and the presence of nutrients was the secondary factor affecting the GPP of phytoplankton. From summer to fall, effect of phosphorus was weakened and effect of nitrogen was enhanced.Qiaohua Zhao Jing Wang Jianjian Wang Julian X.L.Wang 2019Journal of Environmental Sciences2019,31,2:4
17An Aware-Scheduling Security Architecture with Priority-Equal Multi-Controller for SDN显示文摘Current SDN controllers suffer from a series of potential attacks. For example, malicious flow rules may lead to system disorder by introducing unexpected flow entries. In this paper, we propose Mcad-SA, an aware decision-making security architecture with multiple controllers, which could coordinate heterogeneous controllers internally as a 'big' controller. This architecture includes an additional plane, the scheduling plane, which consists of transponder, sensor, decider and scheduler. Meanwhile it achieves the functions of communicating, supervising and scheduling between data and control plane. In this framework, we adopt the vote results from the majority of controllers to determine valid flow rules distributed to switches. Besides, an aware dynamic scheduling(ADS) mechanism is devised in scheduler to intensify security of Mcad-SA further. Combined with perception, ADS takes advantage of heterogeneity and redundancy of controllers to enable the control plane operate in a dynamic, reliable and unsteady state, which results in significant difficulty of probing systems and executing attacks. Simulation results demonstrate the proposed methods indicate better security resilience over traditional architectures as they have lower failure probability when facing attacks.Chao Qi Jiangxing Wu Guozhen Cheng Jianjian Ai Shuo Zhao 2017China Communications2017,14,9:4
