| 1 | Identification of long-range transport pathways and potential sources of PM2.5 and PM10 in Beijing from 2014 to 2015显示文摘Trajectory clustering, potential source contribution function(PSCF) and concentration-weighted trajectory(CWT) methods were applied to investigate the transport pathways and identify potential sources of PM_(2.5)and PM_(10) in different seasons from June 2014 to May 2015 in Beijing.The cluster analyses showed that Beijing was affected by trajectories from the south and southeast in summer and autumn. In winter and spring, Beijing was not only affected by the trajectories from the south and southeast, but was also affected by trajectories from the north and northwest. In addition, the analyses of the pressure profile of backward trajectories showed that backward trajectories, which have important influence on Beijing, were mainly distributed above 970 h Pa in summer and autumn and below 950 h Pa in spring and winter. This indicates that PM_(2.5)and PM_(10) were strongly affected by the near surface air masses in summer and autumn and by high altitude air masses in winter and spring. Results of PSCF and CWT analyses showed that the largest potential source areas were identified in spring, followed by winter and autumn,then summer. In addition, potential source regions of PM_(10) were similar to those of PM_(2.5). There were a clear seasonal and spatial variation of the potential source areas of Beijing and the airflow in the horizontal and vertical directions. Therefore, more effective regional emission reduction measures in Beijing's surrounding provinces should be implemented to reduce emissions of regional sources in different seasons. | Deping Li Jianguo Liu Jiaoshi Zhang Huaqiao Gui Peng Du Tongzhu Yu Jie Wang Yihuai Lu Wenqing Liu Yin Cheng | 2017 | Journal of Environmental Sciences2017,29,6: | 22 |
| 2 | Effectiveness of Jinying capsule on pelvic inflammatory disease in patients with symptom pattern of damp and heat accumulation: a double-blinded, multicenter, randomized, placebo-controlled clinical trial显示文摘OBJECTIVE: To evaluate the therapeutic effectiveness and safety of Jinying capsule on pelvic inflammatory disease(PID) in patients with symptoms identified as the pattern of damp and heat accumulation in terms of Traditional Chinese Medicine(TCM).METHODS: We conducted a double-blinded, multicenter, randomized, placebo-controlled clinical trial which included 155 patients diagnosed with PID and identified as symptom pattern of damp and heat accumulation. They were randomly divided into experimental group(n = 78) and control group(n = 77) according to a random number table. The treatment lasted for a period of 28 d. The experimental group was given Jinying capsules and oral levofloxacin plus oral metronidazole for first 7 d.They continued with Jinying capsules and levofloxacin placebo and metronidazole placebo for another 7 d. For the remaining 14 d, they continued with Jinying capsules only. Whereas, the control group was treated with oral levofloxacin and metronidazole and Jinying capsule placebo for the first 14 d in the same way as the experimental group and then continued with Jinying capsule placebo only for the remaining 14 d. The clinical efficacy was assessed using McCormack scale, TCM symptom pattern scores, physicochemical indexes including white blood cell and erythrocyte sedimentation rate, C-reaction protein, smear of vaginal discharge,and pelvic ultrasound.RESULTS: Comparing McCormack scale between both groups after treatment, the difference in curative effect between both groups was significant (P = 0.0269). The cure rate of the experimental group and control group is 76.32% and 59.46% respectively at week 4. Comparing TCM symptom pattern scores between both groups before and after treatment, the differences in total effective rate were both significant(P < 0.05). The curative effect rate of experimental group is 2.63% and 13.70% of the control group at week 1(P = 0.0131), and73.33% of the experimental group and 56.94% of the control group at week 4(P = 0.0369). No significant differences were found between the two groups on the Physicochemical indexes(all P >0.05). No adverse events or reactions occurred in the experimental groups.CONCLUSION: Jinying capsule can reduce the dosage of antibiotics needed for PID treatment, and improve the symptoms in PID patients. | Yang Yan Lu Yao Zhou Deping Pei Fenglan Li Qin Chen Shuqiong Wang Qiufeng Wang Yanting Jin Zhe Liu Yanxia | 2020 | Journal of Traditional Chinese Medicine2020,40,3: | 10 |

| 4 | Hyaluronic acid facilitates bone repair effects of calcium phosphate cement by accelerating osteogenic expression显示文摘Calcium phosphate cements(CPC)are widely anticipated to be an optimum bone repair substitute due to its satisfied biocompatibility and degradability,suitable to be used in minimally invasive treatment of bone defects.However the clinical application of CPC is still not satisfied by its poor cohesiveness and mechanical properties,in particular its osteoinductivity.Hyaluronic acid reinforced calcium phosphate cements(HA/CPC)showed extroadinary potential not only enhancing the compressive strength of the cements but also significantly increasing its osteoinductivity.In our study,the compressive strength of HA/CPC increased significantly when the cement was added 1%hyaluronic acid(denoted as 1-HA/CPC).In the meantime,hyaluronic acid obviously promoted ALP activity,osteogenic related protein and mRNA expression of hBMSCs(human bone marrow mesenchymal stem cells)in vitro,cement group of HA/CPC with 4%hyaluronic acid adding(denoted as 4-HA/CPC)showed optimal enhancement in hBMSCs differentiation.After being implanted in rat tibial defects,4-HA/CPC group exhibited better bone repair ability and bone growth promoting factors,comparing to pure CPC and 1-HA/CPC groups.The underlying biological mechanism of this stimulation for HA/CPC may be on account of higher osteogenic promoting factors secretion and osteogenic genes expression with hyaluronic acid incorporation.These results indicate that hyaluronic acid is a highly anticipated additive to improve physicochemical properties and osteoinductivity performance of CPCs for minimally invasive healing of bone defects. | Xu Cui Chengcheng Huang Zhizhen Chen Meng Zhang Chunyu Liu Kun Su Jianyun Wang Li Li Renxian Wang Bing Li Dafu Chen Changshun Ruan Deping Wang William W.Lu Haobo Pan | 2021 | Bioactive Materials2021,6,11: | 6 |
| 5 | Strontium modulates osteogenic activity of bone cement composed of bioactive borosilicate glass particles by activating Wnt/β-catenin signaling pathway显示文摘There is a need for synthetic grafts to reconstruct large bone defects using minimal invasive surgery.Our previous study showed that incorporation of Sr into bioactive borate glass cement enhanced the osteogenic capacity in vivo.However,the amount of Sr in the cement to provide an optimal combination of physicochemical properties and capacity to stimulate bone regeneration and the underlying molecular mechanism of this stimulation is yet to be determined.In this study,bone cements composed of bioactive borosilicate glass particles substituted with varying amounts of Sr(0 mol%to 12 mol%SrO)were created and evaluated in vitro and in vivo.The setting time of the cement increased with Sr substitution of the glass.Upon immersion in PBS,the cement degraded and converted more slowly to HA(hydroxyapatite)with increasing Sr substitution.The released Sr2+modulated the proliferation,differentiation,and mineralization of hBMSCs(human bone marrow mesenchymal stem cells)in vitro.Osteogenic characteristics were optimally enhanced with cement(designated BG6Sr)composed of particles substituted with 6mol%SrO.When implanted in rabbit femoral condyle defects,BG6Sr cement supported better peri-implant bone formation and bone-implant contact,comparing to cements substituted with 0mol%or 9mol%SrO.The underlying mechanism is involved in the activation of Wnt/β-catenin signaling pathway in osteogenic differentiation of hBMSCs.These results indicate that BG6Sr cement has a promising combination of physicochemical properties and biological performance for minimally invasive healing of bone defects. | Xu Cui Yadong Zhang Jianyun Wang Chengcheng Huang Yudong Wang Hongsheng Yang Wenlong Liu Ting Wang Deping Wang Guocheng Wang Changshun Ruan Dafu Chen William W.Lu Wenhai Huang Mohamed N.Rahaman Haobo Pan | 2020 | Bioactive Materials2020,5,2: | 3 |
| 6 | The amazing potential of fungi:50 ways we can exploit fungi industrially显示文摘Fungi are an understudied,biotechnologically valuable group of organisms.Due to the immense range of habitats that fungi inhabit,and the consequent need to compete against a diverse array of other fungi,bacteria,and animals,fungi have developed numerous survival mechanisms.The unique attributes of fungi thus herald great promise for their application in biotechnology and industry.Moreover,fungi can be grown with relative ease,making production at scale viable.The search for fungal biodiversity,and the construction of a living fungi collection,both have incredible economic potential in locating organisms with novel industrial uses that will lead to novel products.This manuscript reviews fifty ways in which fungi can potentially be utilized as biotechnology.We provide notes and examples for each potential exploitation and give examples from our own work and the work of other notable researchers.We also provide a flow chart that can be used to convince funding bodies of the importance of fungi for biotechnological research and as potential products.Fungi have provided the world with penicillin,lovastatin,and other globally significant medicines,and they remain an untapped resource with enormous industrial potential. | Kevin D.Hyde Jianchu Xu Sylvie Rapior Rajesh Jeewon Saisamorn Lumyong Allen Grace T.Niego Pranami D.Abeywickrama Janith V.S.Aluthmuhandiram Rashika S.Brahamanage Siraprapa Brooks Amornrat Chaiyasen K.W.Thilini Chethana Putarak Chomnunti Clara Chepkirui Boontiya Chuankid Nimali I.de Silva Mingkwan Doilom Craig Faulds Eleni Gentekaki Venkat Gopalan Pattana Kakumyan Dulanjalee Harishchandra Hridya Hemachandran Sinang Hongsanan Anuruddha Karunarathna Samantha C.Karunarathna Sehroon Khan Jaturong Kumla Ruvishika S.Jayawardena Jian-Kui Liu Ningguo Liu Thatsanee Luangharn Allan Patrick G.Macabeo Diana S.Marasinghe Dan Meeks Peter E.Mortimer Peter Mueller Sadia Nadir Karaba N.Nataraja Sureeporn Nontachaiyapoom Meghan O’Brien Watsana Penkhrue Chayanard Phukhamsakda Uma Shaanker Ramanan Achala R.Rathnayaka Resurreccion B.Sadaba Birthe Sandargo Binu C.Samarakoon Danushka S.Tennakoon Ramamoorthy Siva Wasan Sriprom T.S.Suryanarayanan Kanaporn Sujarit Nakarin Suwannarach Thitipone Suwunwong Benjarong Thongbai Naritsada Thongklang Deping Wei S.Nuwanthika Wijesinghe Jake Winiski Jiye Yan Erandi Yasanthika Marc Stadler | 2019 | Fungal Diversity2019,,4: | 3 |

| 9 | Congestive heart failure in COX2 deficient rats显示文摘Non-steroidal anti-inflammatory drugs(NSAIDs)inhibit prostaglandin(PG)formation by targeting cyclooxygenase(COX)1 and 2.Long-term use of NSAIDs that selectively inhibit COX2 increases the risk for thrombotic events,cardiac failure,and hypertension.However,the underlying mechanisms remain unclear.In this study,COX1-and COX2-deficient rats were created via Cas9/RNA-mediated gene targeting.DNA genotyping and Western blot analysis confirmed successful generation of COX1^(-/-) and COX2^(-/-) rats.Adult COX1^(-/-) rats grew normally,while more than 70%of COX2^(-/-) rats after wean died within 2 months.Echocardiography showed markedly reduced left ventricular ejection fraction and fractional shortening in adult COX2^(-/-) rats compared to those in wildtype(WT)controls.Histological analysis revealed accumulation of inflammatory cells and severe interstitial and perivascular fibrosis in COX2^(-/-)cardiac tissues.Moreover,cardiac ATP and acetyl-Co A production was dramatically decreased in COX2^(-/-) rats.Consistently,the expression of genes related to mitochondrial oxidation,such as those that encode for subunits of pyruvate dehydrogenase complex and acyl Co A dehydrogenases,were downregulated,while glycolytic hexokinase 1(HK1)was upregulated in COX2^(-/-) heart tissues.These observations indicate that COX2-deficient rats developed spontaneously heart failure,likely as a result of dysregulated cardiac energy metabolism. | Qiangyou Wan Deping Kong Qian Liu Shumin Guo Chenchen Wang Yan Zhao Zun-Ji Ke Ying Yu | 2021 | Science China(Life Sciences)2021,64,7: | 3 |
| 10 | Genome-wide profiling of RNA editing sites in sheep显示文摘Background: The widely observed RNA-DNA differences(RDDs) have been found to be due to nucleotide alteration by RNA editing. Canonical RNA editing(i.e., A-to-I and C-to-U editing) mediated by the adenosine deaminases acting on RNA(ADAR) family and apolipoprotein B mRNA editing catalytic polypeptide-like(APOBEC)family during the transcriptional process is considered common and essential for the development of an individual.To date, an increasing number of RNA editing sites have been reported in human, rodents, and some farm animals;however, genome-wide detection of RNA editing events in sheep has not been reported. The aim of this study was to identify RNA editing events in sheep by comparing the RNA-seq and DNA-seq data from three biological replicates of the kidney and spleen tissues.Results: A total of 607 and 994 common edited sites within the three biological replicates were identified in the ovine kidney and spleen, respectively. Many of the RDDs were specific to an individual. The RNA editing-related genes identified in the present study might be evolved for specific biological functions in sheep, such as structural constituent of the cytoskeleton and microtubule-based processes. Furthermore, the edited sites found in the ovine BLCAP and NEIL1 genes are in line with those in previous reports on the porcine and human homologs, suggesting the existence of evolutionarily conserved RNA editing sites and they may play an important role in the structure and function of genes.Conclusions: Our study is the first to investigate RNA editing events in sheep. We screened out 607 and 994 RNA editing sites in three biological replicates of the ovine kidney and spleen and annotated 164 and 247 genes in the kidney and spleen, respectively. The gene function and conservation analysis of these RNA editing-related genes suggest that RNA editing is associated with important gene function in sheep. The putative functionally important RNA editing sites reported in the present study will help future studies on the relationship between these edited sites and the genetic traits in sheep. | Yuanyuan Zhang Deping Han Xianggui Dong Jiankui Wang Jianfei Chen Yanzhu Yao Hesham Y.A.Darwish Wansheng Liu Xuemei Deng | 2019 | Journal of Animal Science and Biotechnology2019,10,2: | 2 |

| 15 | Performance improvement of light-emitting diodes with double superlattices confinement layer显示文摘In this study, the effect of double superlattices on GaN-based blue light-emitting diodes(LEDs) is analyzed numerically. One of the superlattices is composed of InGaN/GaN, which is designed before the multiple quantum wells(MQWs). The other one is AlInGaN/AlGaN, which is inserted between the last QB(quantum barriers) and p-GaN. The crucial characteristics of double superlattices LEDs structure, including the energy band diagrams, carrier concentrations in the active region, light output power, internal quantum efficiency, respectively,were analyzed in detail. The simulation results suggest that compared with the conventional AlGaN electronblocking layer(EBL) LED, the LED with double superlattices has better performance due to the enhancement of electron confinement and the increase of hole injection. The double superlattices can make it easier for the carriers tunneling to the MQWs, especially for the holes. Furthermore, the LED with the double superlattices can effectively suppress the electron overflow out of multiple quantum wells simultaneously. From the result, we argue that output power is enhanced dramatically, and the efficiency droop is substantially mitigated when the double superlattices are used. | Cheng Cheng Yan Lei Zhiqiang Liu Miao He Zhi Li Xiaoyan Yi Junxi Wang Jinmin Li Deping Xiong | 2018 | Journal of Semiconductors2018,39,11: | 1 |
| 16 | Fast and stable K-ion storage enabled by synergistic interlayer and pore-structure engineering显示文摘Carbon-based material has been regarded as one of the most promising electrode materials for potassium-ion batteries(PIBs).However,the battery performance based on reported porous carbon electrodes is still unsatisfactory,while the in-depth K-ion storage mechanism remains relatively ambiguous.Herein,we propose a facile“in situ self-template bubbling”method for synthesizing interlayer-tuned hierarchically porous carbon with different metallic ions,which delivers superior K-ion storage performance,especially the high reversible capacity(360.6 mAh·g^(−1)@0.05 A·g^(−1)),excellent rate capability(158.6 mAh·g^(−1)@10.0 A·g^(−1))and ultralong high-rate cycling stability(82.8%capacity retention after 2,000 cycles at 5.0 A·g^(−1)).Theoretical simulation reveals the correlations between interlayer distance and K-ion diffusion kinetics.Experimentally,deliberately designed consecutive cyclic voltammetry(CV)measurements,ex situ Raman tests,galvanostatic intermittent titration technique(GITT)method decipher the origin of the excellent rate performance by disentangling the synergistic effect of interlayer and pore-structure engineering.Considering the facile preparation strategy,superior electrochemical performance and insightful mechanism investigations,this work may deepen the fundamental understandings of carbon-based PIBs and related energy storage devices like sodium-ion batteries,aluminum-ion batteries,electrochemical capacitors,and dual-ion batteries. | Deping Li Qing Sun Yamin Zhang Xinyue Dai Fengjun Ji Kaikai Li Qunhui Yuan Xingjun Liu Lijie Ci | 2021 | Nano Research2021,14,12: | 1 |
| 17 | The Sedimentation and Formation Mechanism of Lacustrine Endogenic Debris Flow显示文摘The debris flow formed by mass transportation of lacustrine deltaic sediments is quite unique comparedwith subaerial one, and is called 'endogenic debris flow' in this paper. The major diagnostic features ofendogenic debris flow sediments are muddy rip-ups, sandy lumps, randomly distributed carbonaceous plantleaves and rhyotaxitic structure. However, such debris flow can not be completely generalized by the conclu-sion that larger granules are supported by cohesive strength of the matrix. The fact that sediments can betransported in plastic state is considered to be related with two different functions of combined clay-water ma-terials: serving as a matrix in texture and as an adhesive between grains. This paper also discusses the originand sediment types of endogenic debris flow as well as the general concepts of matrix and debris flow. From the viewpoint of 'true debris flow', this paper attempts to generalize and illustrate the basic featuresand variation of endogenic debris flow sediments on the basis of the Bingham (Coulomb-viscosity) model. | Wang Deping Institute of Geology, Shengli Petroleum Administration, Dongying, Shandong Liu Linqun | 1992 | Acta Geologica Sinica(English Edition)1992,66,2: | 1 |

| 19 | Surface Modification of SrAl_2O_4:Eu^(2+),Dy^(3+) and Sr_4Al_(14)O_(25):Eu^(2+),Dy^(3+) Long Lasting Phosphors and Their Application in Water-borne Paint显示文摘In this paper, strontium aluminate phosphors of Sr Al2O4: Eu2+, Dy3+ and Sr4Al14O25: Eu2+, Dy3+ were prepared via solid state reactions and subsequent surface modification with Si O2 by a chemical precipitation method. The strontium aluminate phosphors were characterized by measurement-ray diffraction. According to the analysis by transmission electron microscopy, a continuous Si O2 coating layer with a thickness of 50 nm can be formed on the surface of Si O2-coated phosphor. The covalent bond that attached the phosphor and the Si O2 coating was determined by Fourier transform infrared spectroscopy. The water resistance and optical measurements indicate that the optimum ratio of Si O2 coating to phosphors is 30% by mass. Also, the Si O2-coated phosphors could be used in a water-borne paint with the superior luminous performance. | ZHENG Tong YE Song WANG Deping LI Kang WANG Yue LIU Zhiyuan WANG Hanxuan | 2015 | Journal of the Chinese Ceramic Society2015,,1: | 1 |
| 20 | A Review of the History and Development of Integrated Pest Management(IPM)显示文摘The evolvement of IPM has experienced several significant stages. IPM is an ecosystem as a governance unit. It allows the presence of low numbers of pests because a direct or indirect relationship between biological species and their associated environmental living conditions could keep a long-term ecological balance. IPM also emphasizes overall benefits; it is necessary to integrate all kinds of safe, effective, economic, and simple managements as far as possible. When synthesizing and coordinating various managements, effective control object, effective time limit, effective scope, and effective degree of the individual method should be analysed first. The ultimate goal of IPM is for the sustainable development of agriculture. In the future IPM system engineering, crop resistance, the role of natural enemies, agricultural control, and the application of biological control technologies will be greatly strengthened, and the role of chemical pesticides will be significantly reduced. Safe, effective, and long-lasting control of pest populations will be below the level of harm caused, which could protect the ecological environment and the health of people and livestock, and promote the development of production. | Gong Deping Liu Yongquan Gong Wenliu | 2019 | Plant Diseases and Pests2019,10,2: | 1 |
