| 1 | A review of ecological restoration techniques in fluvial rivers显示文摘Rivers play an important role in people's living and agricultural production,however,intense human activities have broken the original ecological balance,and affected structures and functions of the river ecosystem.To restore the damaged river ecosystem back to a healthy status,effective ecological restoration measures need to be implemented.The main problems that the damaged rivers face are either the locally altered hydrological processes affected by construction of hydraulic facilities,or the deterioration of water quality resulted from pollution emissions,or both.In this study,ecological restoration techniques of the rivers affected by engineering control or pollution are reviewed respectively.In addition,three kinds of methods,i.e.physical,chemical and biological-ecological methods are introduced in details for the rivers affected by water pollution.At present,the development of river restoration techniques shows the following trends:1) the scale of ecological restoration is becoming larger;2) ecological restoration measures are required to meet multiple objectives;and 3) the management of water environment is changing from water quality management to aquatic ecosystem management. | Baozhu Pan Jianping Yuan Xinhua Zhang Zhaoyin Wang Jiao Chen Jinyou Lu Wenjun Yang Zhiwei Li Na Zhao Mengzhen Xu | 2016 | International Journal of Sediment Research2016，31，2： | 18 |
| 2 | An exploratory analysis of benthic macroinvertebrates as indicators of the ecological status of the Upper Yellow and Yangtze Rivers显示文摘这研究在黄和长江的来源区域介绍水的关於生命的集合的第一系统的分析的调查结果。它向一个起始的基础提供作为指示物选择代表性的有机体在这个区域估计河的水的生态的地位。Macroinvertebrates 被认为随着时间的过去由于他们的限制范围和坚持是长期的环境变化的好指示物。macroinvertebrates 的领域调查在长江的来源区域在黄河的来源区域,并且在 2010 年 7 月在 2009 年 8 月被进行。属于 29 个家庭和 59 个类的 macroinvertebrates 的总的来说 68 taxa 被识别。在他们之中是 8 个环节动物, 5 个软体动物, 54 个节肢动物和 1 个另外的动物。在 macroinvertebrates 的黄河, taxa 数字,密度和生物资源的来源区域是 50, 329 个人 m2 和 0.3966 g 分别地弄干重量 m2。为长江的来源区域的相等的数字是 29, 59 个人 m2 和 0.0307 g 弄干重量 m2。在长江的来源区域的更低的 benthic 动物资源被归功于到更高的高度,更高的沉积集中和沼泽地降级。这探索研究的初步的调查结果显示水力发电的发电站在 benthic 居民上有弱影响,但是一系列人的活动引起的沼泽地降级在 macroinvertebrates 的幸存上有灾难的影响。象保守放牧和植被管理那样的生态的保护措施被要求最小化草地降级和 desertification,并且减少土壤侵蚀率和河沉积分泌物。 | PAN Baozhu WANG Zhaoyin LI Zhiwei YU Guo-an XU Mengzhen ZHAO Na Gary BRIERLEY | 2013 | Journal of Geographical Sciences2013，23，5： | 14 |
| 3 | Effect of streambed sediment on benthic ecology显示文摘Benthic macroinvertebrates have been commonly used as indicator species for assessment of aquatic ecology. Streambed sediment, or substrate, plays an important role in habitat conditions for macroinvertebrate communities. Field investigations were done to study the benthic diversity and macroinvertebrate compositions in various stream substrata. Sampling sites with different bed sediment, latitude, and climate were selected along the Yangtze River, the Yellow River, the East River, and the Juma River, in China. The results show that benthic community structures found in different substrata clearly differ, while those found in substrata of similar composition and flow conditions but in different macroclimates are similar. The study, thus, demonstrates that the benthic macroinvertebrate community is mainly affected by substrate composition and flow conditions, but is generally unaffected by latitudinal position and macroclimate. Taxa richness of the macroinvertebrate community was found to be the highest on hydrophyte-covered cobbles, high on moss-covered bedrock, and low on clay beds and cobble beds devoid of plant biomass. Sandy beds are compact and unstable, thus, no benthic macroinvertebrates were found colonizing such substrata. Aquatic insects account for most of the macroinvertebrates collected in these rivers. Different insects dominate in different types of substrata: mainly EPT species (Ephemeroptera, Plecoptera, Trichoptera) in cobble, gravel, and moss-covered bedrock; and Chironomidae larvae in clay beds. The relation between the number of species in the samples and the size of the sampling area fits a power function of the species area. One square meter (1m2) is suggested as the minimum sampling area. A substrate suitability index is proposed by integrating the suitability of sediment, periphyton, and benthic organic materials for macroinvertebrates. The biodiversity of macroinvertebrates increases linearly with the substrate suitability index. Benthic taxa richness increases linearly with the suitability index. | Xuehua DUAN Zhao-Yin WANG Mengzhen XU Kang ZHANG | 2009 | International Journal of Sediment Research2009，24，3： | 12 |
| 4 | The assemblage characteristics of benthic macroinvertebrates in the Yalutsangpo River, the highest major river in the world显示文摘因为与高高度联系的特定的地形学和环境参数,高地河的水的生态系统与低高度河的那些不同。Yalutsangpo, Brahmaputra 河的上面的功课,是在世界上的最高主要的河,越过西藏从西方流动到东方,中国并且流进印度。Macroinvertebrates 被取样从 Yalutsangpo 和它的支流,拉萨, Niyang,和 Parlong Tsangpo 河,从 2009 年 10 月到 2010 年 6 月,学习高地的人物水的生态系统。总的来说,属于 57 个家庭的 110 macroinvertebrate taxa 和 102 个类从盆被识别。macroinvertebrate 集合的生物多样性和作文被高度坡度强烈影响。taxa 丰富和改进 Shannon 牛肉熏香肠索引代表的本地差异在 3,3003,700 m,产地的适用性由于水温度,溶解的氧,和水的植被的更好综合的环境条件在之中是更高的高度高,等等。Macroinvertebrates 根据他们的喂的行为被组织进切碎机, scrapers,食肉动物, collector-filterers,和 collector-gatherers。功能的喂组的分布与产地高度变化了,这被发现。当 scrapers 主要住在 3,5004,500 m 的高度时,切碎机在 2,9004,400 m 的高度是在场的,并且 collector-filterers 比较喜欢 3,5004,000 m。尽管本地 taxa 丰富不在每个地点高,集合的分类作文和密度在不同地点之中极大地变化了,导致与有类似的流动和底层条件的低地河相比的许多更高的地区性的差异。Yalutsangpo 的地区性的累积 taxa 丰富减少了,当高度增加了,更多的家庭被失去。然而,当高度增加了,是最新在场的一些家庭为支撑高地区性的生物多样性是必要的。从 Detrended 通讯分析获得的分类图显示了那高度,河模式,河床结构,河岸结构,和流动条件是在 Yalutsangpo 盆影响了 macroinvertebrate 集合的主要因素。 | Mengzhen XU Zhaoyin WANG Baozhu PAN Guoan YU | 2014 | Frontiers of Earth Science2014，8，3： | 2 |
| 5 | 北方半干旱草原生态系统光合参数的季节和年际变异显示文摘生态系统表观量子效率(α)、最大光合速率(P_(max))和暗呼吸速率(R_(d))不仅反映了生态系统水平光合生理特征,同时也是碳循环模型中光合过程模拟的关键参数。气候和植被因子都会影响光合参数的季节和年际变异,但二者在光合参数调控过程中的相对贡献和作用途径尚不清晰。本研究基于连续12年(2006-2017)的涡度相关观测数据,分析了内蒙古半干旱典型草原光合参数的季节和年际变化规律利用回归分析和结构方程模型(SEM)方法明晰了环境和生理调控的作用途径及相对贡献。结果发现,光合参数(α、P_(max)和R)均表现出单峰的季节变化趋势,并呈现明显的年际波动。温度(T_(a))和土壤含水量(SWC)的变化共同影响光合参数的季节变化,而SWC主导了其年际变异。α和R_(d)的变化主要由T_(a)决定,而P_(max)的变化主要受SWC的影响。SEM模型分析表明,除了直接作用外,环境因子主要通过影响冠层水平气孔导度(gc)对光合参数和碳同化生理过程进行调控。此外,叶面积指数对光合参数特别是Pmax的季节和年际变异起主要调控作用。以上结果明确了环境和植被共同决定了生态系统水平光合参数的季节和年际变异,并强调了在水分受限的草原生态系统中,植被生理调控在光合碳同化能力和碳汇功能评估中的重要作用。 | Cuihai You Yanbing Wang Xingru Tan Bingwei Zhang Tingting Ren Boyu Chen Mengzhen Xu Shiping Chen | 2022 | Journal of Plant Ecology2022，15，5： | 1 |

| 8 | Construction of apricot variety search engine based on deep learning显示文摘Apricot has a long history of cultivation and has many varieties and types. The traditional variety identification methods are timeconsuming and labor-consuming, posing grand challenges to apricot resource management. Tool development in this regard will help researchers quickly identify variety information. This study photographed apricot fruits outdoors and indoors and constructed a dataset that can precisely classify the fruits using a U-net model (F-score:99%), which helps to obtain the fruit's size, shape, and color features. Meanwhile, a variety search engine was constructed, which can search and identify variety from the database according to the above features. Besides, a mobile and web application (ApricotView) was developed, and the construction mode can be also applied to other varieties of fruit trees.Additionally, we have collected four difficult-to-identify seed datasets and used the VGG16 model for training, with an accuracy of 97%, which provided an important basis for ApricotView. To address the difficulties in data collection bottlenecking apricot phenomics research, we developed the first apricot database platform of its kind (ApricotDIAP, http://gffzz2a5b87b2dfb54266ho6wk5wvqqv6566xu.ffgz.tsg.suse.edu.cn/) to accumulate, manage, and publicize scientific data of apricot. | Chen Chen Lin Wang Huimin Liu Jing Liu Wanyu Xu Mengzhen Huang Ningning Gou Chu Wang Haikun Bai Gengjie Jia Tana Wuyun | 2024 | Horticultural Plant Journal2024，10，2： | 0 |
| 9 | Optical pulse repetition rate multiplication based on series-coupled double-ring resonator显示文摘In this paper, optical pulse repetition rate multiplication based on a series-coupled double-ring resonator is proposed. First, the spectral characteristic of the series-coupled double-ring resonator is simulated and the optimum coupling coefficients to achieve a periodic flat-top passband are obtained. Then, high-quality pulse repetition rate multiplication is realized by periodically filtering out spectral lines of the input pulse train. Different multiplication factors N 2, 3, 4, 5 can be obtained by adjusting the ring radii. In addition, compared with a single-ring resonator, the multiplied output pulse train by a series-coupled double-ring resonator exhibits much better power uniformity. | Xiaowei Dong Mengzhen Xu Qiangqiang Zhang | 2016 | Photonics Research2016，4，2： | 0 |
| 10 | LncRNA KCNQ1OT1:Molecular mechanisms and pathogenic roles in human diseases显示文摘Long non-coding RNAs(lncRNAs)exhibit a length more than 200 nucleotides and they are characterized by non-coding RNAs(ncRNA)not encoded into proteins.Over the past few years,the role and development of lncRNAs have aroused the rising attention of researchers.To be specific,KCNQ1OT1,the KCNQ1 opposite strand/antisense transcript 1,is clearly classified as a regulatory ncRNA.KCNQ1OT1 is capable of interacting with miRNAs,RNAs and proteins,thereby affecting gene expression and various cell functions(e.g.,cell proliferation,migration,epithelialemesenchymal transition(EMT),apoptosis,viability,autophagy and inflammation).KCNQ1OT1 is dysregulated in a wide range of human diseases(e.g.,cardiovascular disease,cancer,diabetes,osteoarthritis,osteoporosis and cataract),and it is speculated to act as a therapeutic target for treating various human diseases.On the whole,this review aims to explore the biological functions,underlying mechanisms and pathogenic roles of KCNQ1OT1 in human diseases. | Fangqi Xia Yaqi Wang Mengzhen Xue Leiqi Zhu Dengke Jia Yue Shi Yan Gao Luoying Li Yuanyang Li Silong Chen Guangfu Xu Ding Yuan Chengfu Yuan | 2022 | Genes & Diseases2022，9，6： | 0 |
| 11 | Sn-decorated CeO_(2) with different morphologies for direct dehydrogenation of ethylbenzene显示文摘Three Sn-decorated ceria catalysts with various morphologies(rods,particles,and cubes)were prepared and applied to the direct dehydrogenation of ethylbenzene.Multi-technology characterizations,including X-ray photoelectro n spectroscopy(XPS),H_(2)-tempe rature programmed reduction(H_(2)-TPR),and Raman spectroscopy,prove that the oxygen vacancies are the active sites for ethylbenzene dehydrogenation,which can be regulated by engineering CeO_(2) morphology and enhanced via introducing metal Sn.Given the results of activity test,the catalytic activities for ethylbenzene dehydrogenation over different samples are closely dependent on the amount of oxygen vacancies.The reduced Sn-decorated CeO_(2) catalyst with nanoparticles morphology exhibits better dehydrogenation performance than the other two studied catalysts at 600℃.This work provides an effective approach to regulate the active oxygen vacancies and further enhance the dehydrogenation activities through engineering the surface morphology of the catalyst and introducing suitable additives. | Kai Zhang Guoju Cui Mengzhen Yuan Huiwen Huang Ning Li Jiale Xu Guowei Wang Chunyi Li | 2024 | Journal of Rare Earths2024，42，1： | 0 |
| 12 | A hybrid organic-inorganic perovskite with robust SHG switching显示文摘Owing to the diversity of structure and potential applications in the field of electrics,sensors,and light-emitting diodes,lead halide perovskites have attracted great attention in recent years.Especially those lead halide perovskites with non-centrosymmetric crystal structures usually exhibit nonlinear optical(NLO) characteristics,which may endow them photoelectricity switching functionality.In this work,a lead-based hybrid organic-inorganic perovskite(HOIP) material,trimethyliodomethylammonium lead trichloride(TMIM·PbCl_(3)),is obtained on the basis of tetramethylammonium lead chloride through halogen substitution on the cation part.It shows dual-phase-transition behavior around 345 and 358 K, which is significantly improved.TMIM·PbCl_(3)crystallizes in the chiral space group,P2_(1)2_(1)2_(1), and shows a welldefined second harmonic generation(SHG) response,and good switching endurance,which makes it an excellent candidate for SHG switching material.This work highlights the importance of halogen substitution for crystal engineering and may pave way for the further exploration of the optoelectronic devices. | Mengjuan Yang Hao Cheng Yuqiu Xu Mengzhen Li Yong Ai | 2022 | Chinese Chemical Letters2022，33，4： | 0 |
| 13 | A new multi-source remote sensing image sample dataset with high resolution for flood area extraction:GF-FloodNet显示文摘Deep learning algorithms show good prospects for remote sensingflood monitoring.They mostly rely on huge amounts of labeled data.However,there is a lack of available labeled data in actual needs.In this paper,we propose a high-resolution multi-source remote sensing dataset forflood area extraction:GF-FloodNet.GF-FloodNet contains 13388 samples from Gaofen-3(GF-3)and Gaofen-2(GF-2)images.We use a multi-level sample selection and interactive annotation strategy based on active learning to construct it.Compare with otherflood-related datasets,GF-FloodNet not only has a spatial resolution of up to 1.5 m and provides pixel-level labels,but also consists of multi-source remote sensing data.We thoroughly validate and evaluate the dataset using several deep learning models,including quantitative analysis,qualitative analysis,and validation on large-scale remote sensing data in real scenes.Experimental results reveal that GF-FloodNet has significant advantages by multi-source data.It can support different deep learning models for training to extractflood areas.There should be a potential optimal boundary for model training in any deep learning dataset.The boundary seems close to 4824 samples in GF-FloodNet.We provide GF-FloodNet at http://gffzz32f81fe4765d4826so6wk5wvqqv6566xu.ffgz.tsg.suse.edu.cn/datasets/pengliuair/gf-floodnet and http://gffzzfe5ad979a04a470aso6wk5wvqqv6566xu.ffgz.tsg.suse.edu.cn/s/1vdUCGNAfFwG5UjZ9RLLFMQ?pwd=8v6o. | Yuwei Zhang Peng Liu Lajiao Chen Mengzhen Xu Xingyan Guo Lingjun Zhao | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 14 | Lepr^(+)mesenchymal cells sense diet to modulate intestinal stem/progenitor cells via Leptin-lgf1 axis显示文摘Diet can impact on gut health and disease by modulating intestinal stem cells(ISCs).However,it is largely unknown if and how the ISC niche resp onds to diet and influe nces ISC functi on.Here,we dem on strate that Lepr+mesen chymal cells(MCs)surrounding intestinal crypts sense diet change and provide a novel niche signal to maintain ISC and progenitor cell proliferation.The abundance of these MCs in creases upon admi nistration of a high-fat diet(HFD)but dramatically decreases upon fasting.Depletion of Lepr^(+)MCs resulted in fewer intestinal stem/progenitor cells,compromised the architecture of crypt-villus axis and impaired intestinal regeneration.Furthermore,we showed that IGF1 secreted by Lepr^(+)MCs is an important effector that promotes proliferati on of ISCs and progenitor cells in the intestinal crypt.We con elude that Lepr MCs sense diet alteratio ns and,in turn,modulate intestinal stem/progenitor cell function via a stromal IGF1-epithelial IGF1R axis.These findings reveal that Lepr^(+)MCs are im porta nt mediators lin king systemic diet changes to local ISC function and might serve as a no vel therapeutic target for gut diseases. | Min Deng Christian F.Guerrero-Juarez Xiaole Sheng Jiuzhi Xu Xi Wu Kai Yao Mengzhen Li Xu Yang Guilin Li Jintao Xiao Xiaowei Liu Kaichun Wu Fazheng Ren Qing Nie Maksim V.Plikus Zhengquan Yu Cong Lv | 2022 | Cell Research2022，32，7： | 0 |
| 15 | Reactivation of PPARαalleviates myocardial lipid accumulation and cardiac dysfunction by improving fatty acidβ-oxidation in Dsg2-deficient arrhythmogenic cardiomyopathy显示文摘Arrhythmogenic cardiomyopathy(ACM),a fatal heart disease characterized by fibroadipocytic replacement of cardiac myocytes,accounts for 20%of sudden cardiac death and lacks effective treatment.It is often caused by mutations in desmosome proteins,with Desmoglein-2(DSG2)mutations as a common etiology.However,the mechanism underlying the accumulation of fibrofatty in ACM remains unknown,which impedes the development of curative treatment.Here we investigated the fat accumulation and the underlying mechanism in a mouse model of ACM induced by cardiac-specific knockout of Dsg2(CS-Dsg2^(-/-)).Heart failure and cardiac lipid accumulation were observed in CSDsg2^(-/-)mice.We demonstrated that these phenotypes were caused by decline of fatty acid(FA)β-oxidation resulted from impaired mammalian target of rapamycin(m TOR)signaling.Rapamycin worsened while overexpression of m TOR and 4EBP1 rescued the FAβ-oxidation pathway in CS-Dsg2^(-/-)mice.Reactivation of PPARa by fenofibrate or AAV9-Ppara significantly alleviated the lipid accumulation and restored cardiac function.Our results suggest that impaired m TOR-4EBP1-PPARa-dependent FAβ-oxidation contributes to myocardial lipid accumulation in ACM and PPARa may be a potential target for curative treatment of ACM. | Yubi Lin Ruonan Liu Yanling Huang Zhe Yang Jianzhong Xian Jingmin Huang Zirui Qiu Xiufang Lin Mengzhen Zhang Hui Chen Huadong Wang Jiana Huang Geyang Xu | 2023 | Acta Pharmaceutica Sinica B2023，13，1： | 0 |
