| 1 | The first metagenome of activated sludge from full-scale anaerobic/anoxic/oxic(A2O) nitrogen and phosphorus removal reactor using Illumina sequencing显示文摘The anaerobic/anoxic/oxic(A2O) process is globally one of the widely used biological sewage treatment processes. This is the first report of a metagenomic analysis using Illumina sequencing of full-scale A2O sludge from a municipal sewage treatment plant.With more than 530,000 clean reads from different taxa and metabolic categories, the metagenome results allow us to gain insight into the functioning of the biological community of the A2O sludge. There are 51 phyla and nearly 900 genera identified from the A2O activated sludge ecosystem. Proteobacteria, Bacteroidetes, Nitrospirae and Chloroflexi are predominant phyla in the activated sludge, suggesting that these organisms play key roles in the biodegradation processes in the A2O sewage treatment system.Nitrospira, Thauera, Dechloromonas and Ignavibacterium, which have abilities to metabolize nitrogen and aromatic compounds, are most prevalent genera. The percent of nitrogen and phosphorus metabolism in the A2O sludge is 2.72% and 1.48%, respectively. In the current A2O sludge, the proportion of Candidatus Accumulibacter is 1.37%, which is several times more than that reported in a recent study of A2O sludge. Among the four processes of nitrogen metabolism, denitrification related genes had the highest number of sequences(76.74%), followed by ammonification(15.77%), nitrogen fixation(3.88%) and nitrification(3.61%). In phylum Planctomycetes, four genera(Planctomyces, Pirellula, Gemmata and Singulisphaera) are included in the top 30 abundant genera, suggesting the key role of ANAMMOX in nitrogen metabolism in the A2O sludge. | Mei Tian Fangqing Zhao Xin Shen Kahou Chu Jinfeng Wang Shuai Chen Yan Guo Hanhu Liu | 2015 | Journal of Environmental Sciences2015，27，9： | 20 |
| 2 | Spatial patterns of ecosystem vulnerability changes during 2001–2011 in the three-river source region of the Qinghai-Tibetan Plateau, China显示文摘The three-river source region(TRSR, including Yangtze, Yellow and Lancang rivers), located in the Qinghai-Tibetan Plateau, China, is a typical alpine zone with apparent ecosystem vulnerability and sensitivity. In this paper, we introduced many interdisciplinary factors, such as landscape pattern indices(Shannon diversity index and Shannon evenness index) and extreme climate factors(number of extreme high temperature days, number of extreme low temperature days, and number of extreme precipitation days), to establish a new model for evaluating the spatial patterns of ecosystem vulnerability changes in the TRSR. The change intensity(CI) of ecosystem vulnerability was also analyzed. The results showed that the established evaluation model was effective and the ecosystem vulnerability in the whole study area was intensive. During the study period of 2001–2011, there was a slight degradation in the eco-environmental quality. The Yellow River source region had the best eco-environmental quality, while the Yangtze River source region had the worst one. In addition, the zones dominated by deserts were the most severely deteriorated areas and the eco-environmental quality of the zones occupied by evergreen coniferous forests showed a better change. Furthermore, the larger the change rates of the climate factors(accumulative temperature of ≥10°C and annual average precipitation) are, the more intensive the CI of ecosystem vulnerability is. This study would provide a scientific basis for the eco-environmental protection and restoration in the TRSR. | GUO Bing ZHOU Yi ZHU Jinfeng LIU Wenliang WANG Futao WANG Litao YAN Fuli WANG Feng YANG Guang LUO Wei JIANG Lin | 2016 | Journal of Arid Land2016，8，1： | 16 |
| 3 | Temporal and spatial variability response of groundwater level to land use/land cover change in oases of arid areas显示文摘这份报纸由使用地理信息系统(GIS ) 在 Sangong 河分水岭在干旱绿洲在地下水水平的时间、空间的可变性上在陆地使用 / 盖住变化(LUCC ) 的影响上进行案例研究,遥感(RS ) 和 geostatistical 方法。在在 1978, 1987 和 1998 的分水岭的地下水水平的时间、空间的可变性是由使用 semivariogram 模型和 Kriging 插值的 regressed。在 1978 从天线图象导出的 LUCC 分类地图,在 1987 的 Landsat TM 图象和在 1998 的 Landsat ETM 图象被用来迭加并且与地下水深度的不同等值线图在这些区域分析 LUCC 类型的变换关系。结果证明地下水的变化再装不在整个绿洲是那么重要的,但是时间、空间的 LUCC 在从 1978 ~ 1998 的 20 年的时期期间在正常流动时期或在高流动时期是重要的,并且在他们之间有靠近的关联。通常有地下水水平(33.4%) 的中等空间关联,并且空间自相关距离是 17.78 km。地下水水平严厉地被改变的区域也是陆地资源逐渐地被利用的区域,它主要包括农田,树林,和大楼的利用,工业并且采矿陆地。学习表明 LUCC 强烈在干旱绿洲影响地下水水平的时间、空间的可变性。学习结果具有为讲道理地利用浅地下水资源并且维持干旱绿洲的稳定性的直接、实际的意义。 | YAN Jinfeng CHEN Xi LUO Geping GUO Quanjun | 2006 | Chinese Science Bulletin2006，51，A01： | 12 |
| 4 | Two-photon-excited near-infrared emissive carbon dotsas multifunctional agents for fluorescence imaging andphotothermal therapy显示文摘C dots (CDs) have shown great potential in bioimaging and phototherapy.However, it is challenging to manipulate their fluorescent properties andtherapeutic efficacy to satisfy the requirements for clinic applications. In thisstudy, we prepared S, Se-codoped CDs via a hydrothermal method anddemonstrated that the doping resulted in excitation wavelength-independentnear-infrared (NIR) emissions of the CDs, with peaks at 731 and 820 nm.Significantly, the CDs exhibited a photothermal conversion efficiency of -58.2%,which is the highest reported value for C nanostructures and is comparable tothat of Au nanostructures. Moreover, the CDs had a large two-photon absorptioncross section (-30,045 GM), which allowed NIR emissions and the photothermalconversion of the CDs through the two-photon excitation (TPE) mechanism. Invitro and in vivo tests suggested that CDs can function as new multi functionalphototheranostic agents for the TPE fluorescence imaging and photothermaltheraov of cancer cells. | Minhuan Lan Shaojing Zhao Zhenyu Zhang Li Yan Liang Guo Guangle Niu Jinfeng Zhang Junfang Zhao Hongyan Zhang Pengfei Wang Guangyu Zhu Chun-Sing Lee Wenjun Zhang | 2017 | Nano Research2017，10，9： | 9 |
| 5 | SAD2 in Arabidopsis Functions in Trichome Initiation through Mediating GL3 Function and Regulating GL1,TTG1 and GL2 Expression显示文摘Most genes identified that control Arabidopsis trichome initiation and formation are transcription factors or regulatory com- ponents in transcriptional networks and include GLABROUS1 (GL1), GLABRA2 (GL2), GLABRA3 (GL3) and TRANSPARENT TESTA GLABRA1 (TTG1). Herein, we report that an importin β-like protein, SENSITIVE TO ABA AND DROUGHT2 (SAD2), is required for trichome initiation. Mutations in SAD2 disrupted trichome initiation resulting in reduced trichome number, but had no effect on trichome development or root hair number and development. Expression levels of GL1, MYB23, GL2 and TTG1 were reduced in shoots of sad2 mutants while expression levels of GL3 and ENHANCER OF GLABRA3 (EGL3) were enhanced. Overexpression of GL3 increased trichome numbers in wild type but not in sad2 mutants, indicating that the function of the GL3 protein is altered in the sad2 mutants. In contrast, overexpression of GFP-GL1 decreased trichome number in both wild type and sad2. Double mutant analysis of gl1 sad2 and gl3 sad2 indicated that SAD2 functions genetically, at least in part, in the same pathway with these two genes. Co-immunoprecipitation indicated that the sad2 mutation does not disrupt formation of the TTG1-GL3-GL1 complex. Analysis of GFP fusions of GL1, GL2, GL3 and TTG1 suggested that these proteins are most likely not direct cargo of SAD2. Our data suggest that SAD2 is involved in trichome initiation by regulating these nuclear genes. | Ying Gao Ximing Gong Wanhong Cao Jinfeng Zhao Liqin Fu XuechenWang Karen S.

| 6 | Simultaneous quantification of ginsenoside Rg1 and its metabolites by HPLC–MS/MS:Rg1 excretion in rat bile, urine and feces显示文摘Ginsenoside Rg1(Rg1), the major effective component of ginseng, has been shown to have multiple bioactivities, but low oral bioavailability. The aim of this study was to develop a simple, sensitive and rapid high performance liquid chromatography–tandem mass spectrometry(LC–MS/MS) method, which could be used to validate and quantify the concentrations of Rg1 and its metabolites in Sprague-Dawley rat bile,urine, and feces after oral administration(25 mg/kg). Calibration curves offered satisfactory linearity(r40.995)within the determined ranges. Both intra-day and inter-day variances were less than 15%, and the accuracy was within 80–120%. The excretion recoveries of Rg1, ginsenoside Rh1(Rh1), and protopanaxatriol(Ppt) in bile,urine, and feces combined were all greater than 70%. The fecal excretion recoveries of Rg1, Rh1, and Ppt were40.11%, 22.19%, and 22.88%, respectively, whereas 6.88% of Rg1 and 0.09% of Rh1 were excreted in bile.Urinary excretion accounted for only 0.04% of Rg1. In conclusion, the observed excretion profiles for Rg1 and its metabolites after oral administration are helpful for understanding the poor oral bioavailability of Rg1 and will aid further investigations of Rg1 as a pharmacologically active component. | Chiyu He Ru Feng Yupeng Sun Shifeng Chu Ji Chen Chao Ma Jie Fu Zhenxiong Zhao Min Huang Jiawen Shou Xiaoyang Li Yuzhu Wang Jinfeng Hu Yan Wang Juntian Zhang | 2016 | Acta Pharmaceutica Sinica B2016，6，6： | 6 |
| 7 | A spatial geostatistical analysis of impact of land use development on groundwater resources in the Sangong Oasis Region using remote sensing imagery and data显示文摘In this study, the relationship between land use and cover change (LUCC) and variation of groundwater level and quality in the Sangong Oasis Region was investigated using a spatial geostatistical approach. Specifically, interactions among groundwater, surface water, and LUCC were analyzed through the utilization of geographical information system (GIS), remote sensing (RS) Imagery processing, and geostatistics. Study outputs indicated that recharging into the ground-water did not change significantly during the period from 1978 to 1998. However, both LUCC and groundwater level changed substantially in the Sangong Oasis Region, and their variations were closely correlated to each other spatially and temporally over the past two decades. It confirmed that urbanization process and increased industrial activities were the direct reasons of groundwater table descending and the deterioration of water quality. The results of this research provided a scientific basis for understanding sustainability-related problems and solution options in the oasis areas of western China. | Chen, Xi Yan, JinFeng Chen, Zhi Luo, GePing Song, Qing Xu, WenQiang | 2009 | Journal of Arid Land2009，1，1： | 6 |

| 9 | Detection of cognitive impairment in patients with obstructive sleep apnea hypopnea syndrome using mismatch negativity显示文摘In this experiment,97 patients with obstructive sleep apnea hypopnea syndrome were divided into three groups(mild,moderate,severe) according to minimum oxygen saturation,and 35 healthy subjects were examined as controls.Cognitive function was determined using the mismatch negativity paradigm and the Montreal Cognitive Assessment.The results revealed that as the disease worsened,the mismatch negativity latency was gradually extended,and the amplitude gradually declined in patients with obstructive sleep apnea hypopnea syndrome.Importantly,mismatch negativity latency in severe patients with a persistent time of minimum oxygen saturation < 60 seconds was significantly shorter than that with a persistent time of minimum oxygen saturation > 60 seconds.Correlation analysis revealed a negative correlation between minimum oxygen saturation latency and Montreal Cognitive Assessment scores.These findings indicate that intermittent night-time hypoxemia affects mismatch negativity waveforms and Montreal Cognitive Assessment scores.As indicators for detecting the cognitive functional status of obstructive sleep apnea hypopnea syndrome patients,the sensitivity of mismatch negativity is 82.93%,the specificity is 73.33%,the accuracy rate is 81.52%,the positive predictive value is 85.00%,the negative predictive value is 70.21%,the positive likelihood ratio is 3,and the negative likelihood ratio is 0.23.These results indicate that mismatch negativity can be used as an effective tool for diagnosis of cognitive dysfunction in obstructive sleep apnea hypopnea syndrome patients. | Xiaohui Wen Ningyu Wang Jinfeng Liu Zhanfeng Yan Zhonghai Xin | 2012 | Neural Regeneration Research2012，7，20： | 6 |
| 10 | Numerical simulation of tumor-induced angiogenesis influenced by the extra-cellular matrix mechanical environment显示文摘To investigate tumor-induced angiogenesis underthe influence of the mechanical environments inside and outsidethe tumor, mathematical model of tumor angiogenesiswas developed. In the model, extra-cellular matrix (ECM)was treated as a thin plane. The displacement of ECM isobtained from the force balance equation consisted of theECs traction, the ECM visco-elastic forces and the externalforces. Simulation results show that a layered capillarynetwork is obtained with a well vascularized region at theperiphery of the tumor. The present model can be used asa valid theoretical method in the basic researches in tumor-inducedangiogenesis. | Yan Cai Kalkabay Gulnar Hongyi Zhang Jinfeng Cao Shixiong Xu Quan Long | 2009 | Acta Mechanica Sinica2009，25，6： | 5 |
| 11 | Atypical Occlusion Process Caused by the Merger of a Sea-breeze Front and Gust Front显示文摘An atypical occlusion process that occurred in North China on 14 July 2011 is studied based on both observations and a real-data Weather Research and Forecasting(WRF) model simulation. The results show that this atypical occlusion process was significantly different from the traditional,synoptic-scale occlusion process that occurs within extratropical cyclones. It was caused by the merger of two cold-type mesoscale fronts. One of the fronts developed from the gust front of convective storms,while the other was a sea-breeze front. As the two fronts moved towards each other,the warm air between them was squeezed and separated from the surface. An atypical occluded front was formed when the two fronts merged,with the warm air forced aloft. This kind of occlusion is termed a 'merger' process,different from the well-known 'catch-up'and 'wrap-up' processes. Moreover,local convection was found to be enhanced during the merger process,with severe convective weather produced in the merger area. | Abuduwaili ABULIKEMU XU Xin WANG Yuan DING Jinfeng WANG Yan | 2015 | Advances in Atmospheric Sciences2015，32，10： | 5 |

| 13 | Local inhibition of GABA affects precedence effect in the inferior colliculus显示文摘The precedence effect is a prerequisite for faithful sound localization in a complex auditory environment,and is a physiological phenomenon in which the auditory system selectively suppresses the directional information from echoes.Here we investigated how neurons in the inferior colliculus respond to the paired sounds that produce precedence-effect illusions,and whether their firing behavior can be modulated through inhibition with gamma-aminobutyric acid(GABA).We recorded extracellularly from 36 neurons in rat inferior colliculus under three conditions: no injection,injection with saline,and injection with gamma-aminobutyric acid.The paired sounds that produced precedence effects were two identical 4-ms noise bursts,which were delivered contralaterally or ipsilaterally to the recording site.The normalized neural responses were measured as a function of different inter-stimulus delays and half-maximal interstimulus delays were acquired.Neuronal responses to the lagging sounds were weak when the inter-stimulus delay was short,but increased gradually as the delay was lengthened.Saline injection produced no changes in neural responses,but after local gamma-aminobutyric acid application,responses to the lagging stimulus were suppressed.Application of gamma-aminobutyric acid affected the normalized response to lagging sounds,independently of whether they or the paired sounds were contralateral or ipsilateral to the recording site.These observations suggest that local inhibition by gamma-aminobutyric acid in the rat inferior colliculus shapes the neural responses to lagging sounds,and modulates the precedence effect. | Yanjun Wang Ningyu Wang Dan Wang Jun Jia Jinfeng Liu Yan Xie Xiaohui Wen Xiaoting Li | 2014 | Neural Regeneration Research2014，9，4： | 4 |

| 17 | Low intensity near-infrared light promotes bone regeneration via circadian clock protein cryptochrome 1显示文摘Bone regeneration remains a great clinical challenge. Low intensity near-infrared(NIR) light showed strong potential to promote tissue regeneration, offering a promising strategy for bone defect regeneration. However, the effect and underlying mechanism of NIR on bone regeneration remain unclear. We demonstrated that bone regeneration in the rat skull defect model was significantly accelerated with low-intensity NIR stimulation. In vitro studies showed that NIR stimulation could promote the osteoblast differentiation in bone mesenchymal stem cells(BMSCs) and MC3T3-E1 cells, which was associated with increased ubiquitination of the core circadian clock protein Cryptochrome 1(CRY1) in the nucleus. We found that the reduction of CRY1 induced by NIR light activated the bone morphogenetic protein(BMP) signaling pathways, promoting SMAD1/5/9 phosphorylation and increasing the expression levels of Runx2 and Osterix. NIR light treatment may act through sodium voltage-gated channel Scn4a, which may be a potential responder of NIR light to accelerate bone regeneration. Together, these findings suggest that low-intensity NIR light may promote in situ bone regeneration in a CRY1-dependent manner, providing a novel, efficient and non-invasive strategy to promote bone regeneration for clinical bone defects. | Jinfeng Peng Jiajia Zhao Qingming Tang Jinyu Wang Wencheng Song Xiaofeng Lu Xiaofei Huang Guangjin Chen Wenhao Zheng Luoying Zhang Yunyun Han Chunze Yan Qian Wan Lili Chen | 2022 | International Journal of Oral Science2022，14，4： | 2 |
| 18 | A New Indicator for Global Food Security Assessment: Harvested Area Rather Than Cropland Area显示文摘Cropland area has long been used as a key indicator of food security.However,grain yield is not solely controlled by the area of the cropland.Therefore,we proposed a new indicator to assess food security.Results show that from 1992 to 2004,the global cropland area increased by 840200 km^(2)(99.4%),but the grain yield increased only by 310 million t(29.1%);and from 2004 to 2015,the cropland area decreased by 39000 km^(2)(4.64%),but the grain yield increased by 370 million t(70.84%).This result showed that grain yield was not linearly correlated with cropland area,and delimiting the threshold of cropland protection may not guarantee food security.Combined with further correlation analysis,we found that the increase in the global grain yield was more closely related to the harvested area(R^(2)=0.94),which indicated that the harvested area is a more scientific and accurate indicator than cropland area in terms of guaranteeing food security.Therefore,if governments want to ensure the food security,they should choose a new and more accurate indicator:harvested area rather than cropland area. | SONG Fengjiao WANG Shijie BAI Xiaoyong WU Luhua WANG Jinfeng LI Chaojun CHEN Huan LUO Xuling XI Huipeng ZHANG Sirui LUO Guofeng YAN Mengqi ZHEN Qingqing | 2022 | Chinese Geographical Science2022，32，2： | 2 |
| 19 | High efficiency ternary organic solar cells enabled by compatible dual-donor strategy with planar conjugated structures显示文摘Ternary organic solar cells(OSCs) have received extensive attention for improving the power conversion efficiency(PCE) of organic photovoltaics(OPVs). In this work, a novel donor material(ECTBD) consisting of benzodithiophene(BDT) central electron donor unit was developed and synthesized. The small molecular donor has the same central unit as PM6. The addition of ECTBD into PM6:Y6 system could improve the morphology of active blend layer. In addition, ECTBD showed good morphologically compatibility when blending with PM6:Y6 host, resulting in the improvement of fill factor and current density. As a result, the ternary devices based on PM6:ECTBD:Y6 ternary system achieved a highest PCE of 16.51% with fill factor of 76.24%, which was much higher than that of the binary devices(15.7%). Overall, this work provided an effective strategy to fabricate highly efficient ternary organic solar cells through design of the novel small molecular donor as the third component. | Sanhui Chen Tingting Yan Billy Fanady Wei Song Jinfeng Ge Qiang Wei Ruixiang Peng Guohui Chen Yingping Zou Ziyi Ge | 2020 | Science China Chemistry2020，63，7： | 2 |
| 20 | Critical Cooling Rate for the Glass Formation of Ferromagnetic Fe_(80)P_(13)C_7 Alloy显示文摘In this paper the critical cooling rate, Rc, for the glass formation of Fe80P13C7 alloy has been determined using both Uhlmann's and Barandiaran-Colmenero's method. In Uhlmann's method, all kinds of the expressions of △Gl-s (T) and η (T) determined using the different modes and methods had been investigated. It is indicated that the R c for the glass formation of Fe80P13C7 alloy can be estimated to be 349 K/s by Uhlmann's method based on the appropriate expressions of △Gl-s (T) and η (T). The calculated result accords with our experimental result. The R c for the glass formation of Fe80P13C7 alloy has also been determined to be 0.49 K/s using Barandiaran-Colmenero's method. This resultant R c is unreasonable low and it indicates that Barandiaran-Colmenero's method does not suit to Fe-based alloy. | Kai XU Yan WANG Jinfeng LI Qiang LI | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，1： | 2 |
