| 1 | Major advances in studies of the physical geography and living environment of China during the past 70 years and future prospects显示文摘The natural environment provides material essentials for human survival and development. The characteristics,processes, regional differentiation and forcing mechanisms of the elements of the natural environment(e.g. geomorphology,climate, hydrology, soil, etc.) are the main objects of research in physical geography. China has a complex natural environment and huge regional differentiation and therefore it provides outstanding reserach opportunities in physical geography. This review summarizes the most important developments and the main contributions of research in the physical geography and human living environment in China during the past 70 years. The major topics addressed are the uplift of the Tibetan Plateau and the evolution of its cryosphere, the development of fluvial systems, the acidification of the vast arid region of the Asian interior, variations in the monsoon and westerly climate systems on multiple timescales, the development of lakes and wetlands, the watershed system model, soil erosion, past human-environment interactions, biogeography, and physical geographic zonality. After briefly introducing international research developments, we review the history of research in physical geography in China, focusing on the major achievements and major academic debates, and finally we summarize the status of current research and the future prospects. We propose that in the context of the national demand for the construction of an ecological civilization, we should make full use of the research findings of physical geography, and determine the patterns and mechanisms of natural environmental processes in order to continue to promote the continued contribution of physical geography to national development strategies, and to further contribute to the theory of physical geography from a global perspective. | Fahu CHEN Bojie FU Jun XIA Duo WU Shaohong WU Yili ZHANG Hang SUN Yu LIU Xiaomin FANG Boqiang QIN Xin LI Tingjun ZHANG Baoyuan LIU Zhibao DONG Shugui HOU Lide TIAN Baiqing XU Guanghui DONG Jingyun ZHENG Wei YANG Xin WANG Zaijun LI Fei Wang Zhenbo HU Jie WANG Jianbao LIU Jianhui CHEN Wei HUANG Juzhi HOU Qiufang CAI Hao LONG Ming JIANG Yaxian HU Xiaoming FENG Xingguo MO Xiaoyan YANG Dongju ZHANG Xiuhong WANG Yunhe YIN Xiaochen LIU | 2019 | Science China Earth Sciences2019，62，11： | 11 |
| 2 | Review of operational management in intelligent agriculture based on the Internet of Things显示文摘This review aims to gain insight into the current research and application of operational management in the area of intelligent agriculture based on the Internet of Things(IoT),and consequently,identify existing shortcomings and potential issues.First,we use the Java application CiteSpace to analyze co-citation networks in the literature related to the operational management of IoT-based intelligent agriculture.From the literature analysis results,we identify three major fields:(1)the development of agricultural IoT(Agri-IoT)technology,(2)the precision management of agricultural production,and(3)the traceability management of agricultural products.Second,we review research in the three fields separately in detail.Third,on the basis of the research gaps identified in the review and from the perspective of integrating and upgrading the entire agricultural industry chain,additional research directions are recommended from the following aspects:The operational management of agricultural production,product processing,and product sale and after-sale service based on Agri-IoT.The theoretical research and practical application of combining operational management theories and IoT-based intelligent agriculture will provide informed decision support for stakeholders and drive the further development of the entire agriculture industry chain. | Xiangpei HU Lijun SUN Yaxian ZHOU Junhu RUAN | 2020 | Frontiers of Engineering Management2020，7，3： | 4 |

| 6 | circRNAs deregulation in exosomes derived from BEAS-2B cells is associated with vascular stiffness induced by PM_(2.5)显示文摘As an environmental pollutant,ambient fine particulate matter (PM_(2.5)) was linked to cardiovascular diseases.The molecular mechanisms underlying PM_(2.5)-induced extrapulmonary disease has not been elucidated clearly.In this study the ambient PM_(2.5)exposure mice model we established was to explore adverse effects of vessel and potential mechanisms.Long-term PM_(2.5)exposure caused reduced lung function and vascular stiffness in mice.And chronic PM_(2.5)induced migration and epithelial-mesenchymal transition (EMT) phenotype in BEAS-2B cells.After PM_(2.5)treatment,the circRNAs and mRNAs levels of exosomes released by BEAS-2B cells were detected by competing endogenous RNA (ceRNA) array,which contained 1664 differentially expressed circRNAs (DE-circRNAs) and 308 differentially expressed m RNAs (DE-mRNAs).By bioinformatics analysis on host genes of DE-circRNAs,vascular diseases and some pathways related to vascular diseases including focal adhesion,tight junction and adherens junction were enriched.Then,ceRNA network was constructed,and DE-mRNAs in ceRNA network were conducted functional enrichment analysis by Ingenuity Pathway Analysis,which indicated that hsa_circ_0012627,hsa_circ_0053261and hsa_circ_0052810 were related to vascular endothelial dysfunction.Furthermore,it was verified experimentally that Exo^(PM2.5)could induce endothelial dysfunction by increased endothelial permeability and decreased relaxation in vitro.In present study,we investigated in-depth knowledge into the molecule events related to PM_(2.5) toxicity and pathogenesis of vascular diseases. | Qingping Liu Yaling Zhang Bin Han Mengruo Wang Huaifang Hu Jie Ning Wentao Hu Meiyu Chen Yaxian Pang Yuanyuan Chen Lei Bao Yujie Niu Rong Zhang | 2024 | Journal of Environmental Sciences2024，，3： | 0 |
