| 1 | Knowledge domain and emerging trends in Alzheimer’s disease: a scientometric review based on CiteSpace analysis显示文摘Alzheimer’s disease is the most common cause of dementia.It is an increasingly serious global health problem and has a significant impact on individuals and society.However,the precise cause of Alzheimer’s disease is still unknown.In this study,11,748 Web-of-Science-indexed manuscripts regarding Alzheimer’s disease,all published from 2015 to 2019,and their 693,938 references were analyzed.A document co-citation network map was drawn using CiteSpace software.Research frontiers and development trends were determined by retrieving subject headings with apparent changing word frequency trends,which can be used to forecast future research developments in Alzheimer’s disease. | Shuo Liu Ya-Ping Sun Xu-Ling Gao Yi Sui | 2019 | Neural Regeneration Research2019，14，9： | 59 |
| 2 | Exotic origin of the Chinese continental shelf: new insights into the tectonic evolution of the western Pacific and eastern China since the Mesozoic显示文摘The effect of paleo-Pacific subduction on the geological evolution of the western Pacific and continental China is likely complex. Nevertheless, our analysis of the distribution of Mesozoic granitoids in the eastern continental China in space and time has led us to an interesting conclusion: The basement of the continental shelf beneath East and South China Seas may actually be of exotic origin geologically unrelated to the continental lithosphere of eastern China. By accepting the notion that the Jurassic–Cretaceous granitoids in the region are genetically associated with western Pacific subduction and the concept that subduction may cease to continue only if the trench is being jammed, then the termination of the granitoidmagmatism throughout the vast region at *88 ± 2 Ma manifests the likelihood of ‘‘sudden'', or shortly beforehand(*100 Ma), trench jam of the Mesozoic western Pacific subduction. Trench jam happens if the incoming‘‘plate'' or portion of the plate contains a sizeable mass that is too buoyant to subduct. The best candidate for such a buoyant and unsubductable mass is either an oceanic plateau or a micro-continent. We hypothesize that the basement of the Chinese continental shelf represents such an exotic, buoyant and unsubductable mass, rather than seaward extension of the continental lithosphere of eastern China. The locus of the jammed trench(i.e., the suture) is predictably located on the shelf in the vicinity of, and parallel to, the arc-curved coastal line of the southeast continental China. It is not straightforward to locate the locus in the northern section of the East China Sea shelf because of the more recent(\20 Ma) tectonic re-organization associated with the opening of the Sea of Japan. We predict that the trench jam at *100 Ma led to the re-orientation of the Pacific plate motion in the course of NNW direction as inferred from the age-progressive Emperor Seamount Chain of Hawaiian hotspot origin(its oldest unsubdued Meiji and Detroit seamounts are *82 Ma),making the boundary between the Pacific plate and the newly accreted plate of eastern Asia a transform fault at the location east of the continental shelf of exotic origin. This explains the apparent *40 Myr magmatic gap from *88to *50 Ma prior to present-day western Pacific subduction initiation. We propose that basement penetration drilling on well-chosen sites is needed to test the hypothesis in order to reveal the true nature of the Chinese continental shelf basement. This testing becomes critical and cannot longer be neglected in order to genuinely understand the tectonic evolution of the western Pacific and its effect on the geology of eastern China since the Mesozoic, includingthe cratonic lithosphere thinning, related magmatism/mineralization, and the mechanism of the subsequent South China Sea opening, while also offering novel perspectives on aspects of the plate tectonics theory. We also suggest the importance of future plate tectonic reconstruction of the western Pacific to consider the nature and histories of the Chinese continental shelf of exotic origin as well as the probable transform plate boundary from *100 to*50 Ma. Effort is needed to reveal the true nature and origin of the *88 ± 2 Ma granitic gneisses in Taiwan and the 110–88 Ma granitoids on the Hainan Island. | Yaoling Niu Yi Liu Qiqi Xue Fengli Shao Shuo Chen Meng Duan Pengyuan Guo Hongmei Gong Yan Hu Zhenxing Hu Juanjuan Kong Jiyong Li Jinju Liu Pu Sun Wenli Sun Lei Ye Yuanyuan Xiao Yu Zhang | 2015 | Science Bulletin2015，60，18： | 32 |
| 3 | CLINICAL APPLICATION OF BODY DIFFUSION WEIGHTED MR IMAGING IN THE DIAGNOSIS AND PREOPERATIVE N STAGING OF CERVICAL CANCER显示文摘Objective To evaluate the clinical impact of body diffusion weighted imaging (DWI) on the diagnosis and preoperative N staging of cervical cancer. Methods Twenty-four patients (mean age 37.9 years old) with proved cervical cancer by cervical biopsy and 24 female patients with other suspected pelvic abnormalities received preoperative body DWI scan. Results of body DWI were compared with pathological findings. The apparent diffusion coefficient (ADC) values of normal cervix and different pathological types of cervical cancer were compared. ADC value of normal or inflammatory lymph nodes was also compared with that of metastatic ones. Student's t test was used for statistical analysis. Results There were 5 adenocarcinomas and 19 epitheliomas showed with biopsy results, and DWI showed 21 cervical lesions out of them (87.5%). ADC values of the normal cervix (n = 24), epithelioma (n = 19), and adenocar- cinoma (n = 5) were (1.73 ± 0.31) ×10-3, (0.88 ± 0.22) ×10-3, and (1.08 ± 0.12) ×10-3 mm2/s, respectively. Statistical analysis showed significant difference in ADC value between normal cervical tissue and either tumor tissues (both P < 0.01). In patients had lymphadenectomy (n = 24), totally 67 lymph nodes including 16 metastatic lymph nodes were pathologically analyzed, and DWI showed 66 (98.5%) out of them. ADC values of normal/inflammatory and metastatic lymph nodes were (1.07 ± 0.16) ×10-3 and (0.77 ± 0.13) ×10-3 mm2/s (P < 0.01). Receiver operating characteristic (ROC) curve of ADC value of metastatic lymph node showed that area under curve was 0.961. Conclusions ADC value in cervical carcinoma is lower than that in normal cervix, and ADC may have predictive value in subtype discrimination. ADC value may improve the preoperative characterization of lymph node metastasis. And at least abdominal and pelvic DWI scan is suggested for N staging evaluation in such patients. | Hua-dan Xue Shuo Li Fei Sun Hong-yi Sun Zheng-yu Jin Jia-xin Yang Mei Yu | 2008 | Chinese Medical Sciences Journal2008，23，3： | 28 |
| 4 | APPLICATION OF WHOLE BODY DIFFUSION WEIGHTED MR IMAGING FOR DIAGNOSIS AND STAGING OF MALIGNANT LYMPHOMA显示文摘Objective To evaluate the clinical impact of whole body diffusion weighted imaging (WB-DWI) on diagnosis and staging of malignant lymphoma. Methods Thirty-one patients with suspected lymphadenopathy were enrolled. WB-DWI was performed by using short TI inversion recovery echo-planar imaging sequence with free breathing and built-in body coil. Axial T2- weighted imaging images of the same location were used as reference. The results of WB-DWI were compared with pathological results and other imaging modalities. The mean apparent diffusion coefficient (ADC) values of different kinds of lymph nodes were compared. Results WB-DWI was positive in all 18 cases with lymphoma, 5 cases with metastatic lymph nodes and 4 of 8 cases with benign lymphadenopathy. The mean ADC value of lymphomatous, metastatic and benign lymph nodes was (0.87 ± 0.17) × 10-3, (0.98 ± 0.09) × 10-3 and (1.20 ± 0.10) × 10-3 mm2/s. There was significant difference in ADC value between benign lymph nodes and other two groups (P < 0.01). The sensitivity, specificity and accuracy of WB-DWI in diagnosis of lymphoma were 100% (18/18), 30.8% (4/13) and 71.0% (22/31). When an ADC value of 1.08 × 10-3 mm2/s was used as the threshold value for differentiating malignant from benign lymph nodes, the best results were obtained with sensitivity of 87.8% and specificity of 91.3%. Sixteen of eighteen cases (88.9%) of lymphoma were accurately staged in accordance with clinical staging. Conclusions WB-DWI is a sensitive, but less specific technique for diagnosis of lymphoma. It is difficult to differentiate lymphomatous from metastatic lymph nodes using WB-DWI. However, it is a valuable imaging modality for staging of patients with malignant lymphoma. | Shuo Li Hua-dan Xue Jian Li Fei Sun Bo Jiang Dong Liu Hong-yi Sun Zheng-yu Jin | 2008 | Chinese Medical Sciences Journal2008，23，3： | 18 |
| 5 | Phylogeny and Classifcation of Prunus sensu lato (Rosaceae)显示文摘The classifcation of the economically important genus Prunus L.sensu lato(s.l.)is controversial due to the high levels of convergent or the parallel evolution of morphological characters.In the present study,phylogenetic analyses of ffteen main segregates of Prunus s.l.represented by eighty-four species were conducted with maximum parsimony and Bayesian approaches using twelve chloroplast regions(atpB-rbcL,matK,ndhF,psbA-trnH,rbcL,rpL16,rpoC1,rps16,trnS-G,trnL,trnL-F and ycf1)and three nuclear genes(ITS,s6pdh and SbeI)to explore their infrageneric relationships.The results of these analyses were used to develop a new,phylogeny-based classifcation of Prunus s.l.Our phylogenetic reconstructions resolved three main clades of Prunus s.l.with strong supports.We adopted a broad-sensed genus,Prunus,and recognised three subgenera corresponding to the three main clades:subgenus Padus,subgenus Cerasus and subgenus Prunus.Seven sections of subgenus Prunus were recognised.The dwarf cherries,which were previously assigned to subgenus Cerasus,were included in this subgenus Prunus.One new section name,Prunus L.subgenus Prunus section Persicae(T.T.Yü&L.T.Lu)S.L.Zhou and one new species name,Prunus tianshanica(Pojarkov)S.Shi,were proposed. | Shuo Shi Jinlu Li Jiahui Sun Jing Yu Shiliang Zhou | 2013 | Journal of Integrative Plant Biology2013，55，11： | 18 |
| 6 | Simple and cost-effective methods for precise analysis of trace element abundances in geological materials with ICP-MS显示文摘Inductively coupled plasma mass spectrometry(ICP-MS) is the most commonly used technique to determine the abundances of trace elements in a wide range of geological materials. However, incomplete sample digestion, isobaric interferences and instrumental drift remain obvious problems that must be overcome in order to obtain precise and accurate results. For this reason, we have done many experiments and developed a set of simple, cost-effective and practical methods widely applicable for precise and rapid determination of trace element abundances in geological materials using ICP-MS. Commonly used high-pressure digestion technique is indeed effective in decomposing refractory phases, but this inevitably produces fluoride complexes that create new problems. We demonstrate that the fluoride complexes formed during high-pressure digestion can be readily re-dissolved using high-pressure vessel at 190 °C for only 2 h for 50 mg sample. In the case of isobaric interferences, although oxide(e.g., MO+/M+) and hydroxide(e.g., MOH+/M+) productivity is variable between runs, the(MO+/M+)/(Ce O+/Ce+)and(MOH+/M+)/(Ce O+/Ce+) ratios remain constant, making isobaric interference correction for all other elements of interest straightforward, for which we provide an easy-to-use off-line procedure. We also show that mass-time-intensity drift curve is smooth as recognized previously, for which the correction can be readily done by analyzing a quality-control(QC) solution and using off-line Excel VBA procedure without internal standards. With these methods, we can produce data in reasonable agreement with recommended values of international rock reference standards with a relative error of <8% and precision generally better than 5%. Importantly, compared to the widely used analytical practice, we can effectively save >60% of time(e.g., <24 h vs. >60 h). | Shuo Chen Xiaohong Wang Yaoling Niu Pu Sun Meng Duan Yuanyuan Xiao Pengyuan Guo Hongmei Gong Guodong Wang Qiqi Xue | 2017 | Science Bulletin2017，62，4： | 17 |
| 7 | Trocar-site hernia after gynecological laparoscopic surgery: a 20-year, single-center experience显示文摘Background:Trocar-site hernia(TSH)is a serious complication after laparoscopic procedures.Although it is a rare entity,it have life-threatening consequences.This study aimed to retrospectively analyze the potential associated factors for TSH following gynecologic laparoscopy and summarize prevention strategies based on our experience.Methods:We searched for gynecological laparoscopic surgeries in the medical records system of Peking Union Medical College Hospital(PUMCH)from August 1998 to July 2018 and further sifted through the results for cases involving TSH.All included patients were divided into different groups according to patient characteristics,and the rate of TSH was compared among groups.Moreover,the detailed information of all patients with TSH was recorded and analyzed.Statistical analyses were performed with GraphPad Prism 6.Results:The approximate total rate of post-operative TSH among gynecologic laparoscopy procedures performed at PUMCH in the last 20 years was 0.016%(9/55,244).The rate of TSH was significant higher in elder patients(>60 years old;3/2686,0.112%)than in younger patients(<60 years old,6/52,558;0.011%,P=0.008).Moreover,the approximate rate of TSH was significantly higher after single-incision laparoscopic surgery(SILS,2/534,0.357%)than conventional laparoscopic surgery(7/54,710,0.013%,P=0.003).The average age of patients with TSH was 53.4 years(range,35.0-79.0 years).Two of the nine patients had late-onset TSH following SILS;the other seven had early-onset TSH following conventional laparoscopy.Five TSH cases occurred at right lateral port sites,and the remaining three occurred at the umbilical port site.All patients underwent repair surgery,and one required small bowel resection.Conclusion:Older age and SILS are potential associated factors for TSH development,while reducing excessive manipulation and improving suturing skills,especially at the umbilical trocar site following SILS and the right lateral trocar site,can avoid herniation. | Ya-Pei Zhu Shuo Liang Lan Zhu Zhi-Jing Sun Jing-He Lang | 2019 | Chinese Medical Journal2019，，22： | 16 |
| 8 | MR DIFFUSION WEIGHTED IMAGING FOR EVALUATION OF RADIOTHERAPEUTIC EFFECTS ON RABBIT VX2 TUMOR MODEL显示文摘Objective To investigate the feasibility of magnetic resonance (MR) diffusion weighted imaging (DWI) for evaluation of radiotherapeutic effects on rabbit VX2 tumor model. Methods Sixteen New Zealand white rabbits received a subcutaneous implantation of VX2 tumor cell suspension 0.5 mL (4×107 cells/mL) in their right thighs to set up tumor model. And 2 weeks later they were randomly divided into therapy group (Group T, n = 10) and control group (Group C, n = 6). Group T received radiotherapy at a single dose of 10 Gy. MR imaging (MRI) scan including short TI inversion recovery echo-planar imaging DWI, T1-weighted imaging (T1WI) and T2-weighted imaging (T2WI) sequences were performed 1 day prior to as well as 1 day, 2 days, 3 days and 7 days after radiotherapy. Group C received only MRI scan at the same time points without any treatment. MRI appearance on T2WI, T1WI, and DWI images was compared and tumor volume was calculated. Apparent diffusion coefficient (ADC) values of the tumor were evaluated in all cases. HE staining was used for pathological study. Results Necrosis (n = 8) and hemorrhage (n = 2) were seen gradually on T2WI and T1WI images of Group T after time point of day 2 after irradiation. In Group C, no obvious necrosis was found until day 7. There was no significant difference in tumor volume between the two groups before radiotherapy. After radiotherapy, tumors in Group T showed a gradual growth but not as obvious as Group C. There was a significant difference in tumor volume between the two groups from day 2 on (P < 0.05). ADC value changed dramatically right from the 1st day after radio- therapy in Group T [(0.99 ± 0.15) ×10-3 mm2/s for 1 day before radiotherapy, (1.23 ± 0.08) ×10-3, (1.45 ± 0.07) ×10-3, (1.63 ± 0.06) ×10-3, and (2.02 ± 0.18) ×10-3 mm2/s for day 1, 2, 3, and 7]; and ADC value had no significant changes after radiotherapy in Group C except day 7 [(1.07 ± 0.08) ×10-3 mm2/s for 1 day before radiotherapy, (1.03 ± 0.04) × 10-3, (1.05 ± 0.02) ×10-3, (1.05 ± 0.05) ×10-3, and (0.95 ± 0.07) ×10-3 mm2/s for day 1, 2, 3, and 7]. There was significant difference in ADC value between the two groups for each time point after radiotherapy (P < 0.01). Pathological study showed that the number of viable tumor cells in Group T decreased 1 day after radiotherapy, and the inflammatory cell infiltration was marked and almost all viable tumor cells disappeared by day 7 after radiotherapy. Conclusions DWI is a new promising technique for monitoring radiotherapy outcomes. ADC value may give a prior clue on physiological changes of radiotherapy before routine MRI could tell. | Shuo Li Hua-dan Xue Xin-hai Wang Fei Sun Bo Jiang Dong Liu Jing Lei Zheng-yu Jin | 2008 | Chinese Medical Sciences Journal2008，23，3： | 15 |

| 13 | Genome Characteristics and Evolution of Pseudorabies Virus Strains in Eastern China from 2017 to 2019显示文摘Since late 2011,outbreaks of pseudorabies virus(PRV)have occurred in southern China causing major economic losses to the pig industry.We previously reported that variant PRV forms and recombination in China could be the source of continued epidemics.Here,we analyzed samples from intensive pig farms in eastern China between 2017 and 2019,and sequenced the main glycoproteins(gB,gC,gD,and gE)to study the evolution characteristics of PRV.Based on the gC gene,we found that PRV variants belong to clade 2 and detected a founder effect during by the PRV epidemic.In addition,we detected inter-and intra-clade recombination;in particular,inter-clade recombination in the gB genes of strains FJ-ZXF and FJ-W2,which were recombinant with clade 1 strains.We also found specific amino-acid changes and positively selected sites,possibly associated with functional changes.This analysis of the emergence of PRV in China illustrates the need for continuous monitoring and the development of vaccines against specific variants of PRV. | Xiaofeng Zhai Wen Zhao Kemang Li Cheng Zhang Congcong Wang Shuo Su Jiyong Zhou Jing Lei Gang Xing Haifeng Sun Zhiyu Shi Jinyan Gu | 2019 | Virologica Sinica2019，34，6： | 12 |
| 14 | Effect of Chinese Medicine on No or Slow Reflow after Percutaneous Coronary Intervention in Myocardial Infarction Patients: A Systematic Review and Meta-Analysis显示文摘Objective:To systematic review the effect of Chinese medicine(CM)on no or slow reflow after percutaneous coronary intervention(PCI)in myocardial infarction(MI)patients.Methods:The Pub Med,EMBASE databases,Cochrane Central Register of Controlled Trials(CENTRAL),Web of Science,China National Knowledge Infrastructure(CNKI),Chinese BioMedical Literature Database(CBM),Wanfang Knowledge Service Platform(Wanfang Database)and Chinese Scientific Journal Database(VIP)were searched up to December 2017.Randomized controlled trials(RCTs)which evaluated the effect of CM therapies on no or slow reflow after PCI in MI patients were included.The primary outcome was the effect of reperfusion.Secondary outcomes were left ventricular ejection fraction,incidence of major adverse cardiovascular events and adverse effect.Results:Ten RCTs covering 814 patients were included.Two studies revealed that the incidence of no or slow reflow was less in Shenmai Injection(参麦注射液)group than in the control group measured by thrombolysis in myocardial infarction(TIMI)2(risk ratio=0.55,95%confidence interval 0.38 to 0.81,P=0.003,I^2=37%).Two studies indicated that Salvianolate Injection showed no additional benefit on no or slow reflow measured by corrected TIMI frame count compared with the conventional treatment(mean difference–4.24,95% confidence interval–13.03 to 4.54,P=0.34,I^2=86%).In addition,Tongxinluo Capsules(通心络胶囊),Danhong Injection(丹红注射液)and Xuesaitong Injection(血塞通注射液)may have the potential to reduce no or slow reflow measured during or after PCI in individual studies.Conclusions:Current evidence from RCTs are not sufficient to evaluate the effect of CM adjuvant therapies on no or slow reflow after PCI for MI patients.The included studies are limited by small sample size and unclear baseline conditions.Further rigorously designed researches and verification studies with sufficient number of patients are warranted. | ZHANG Xiao-yu SUN Yang YANG Xin-yu HU Jia-yuan ZHENG Rui CHEN Shi-qi LI Min LI Cheng-yu JIANG Yin LIU Shuo ZHAO Chen XING Yan-wei SHANG Hong-cai | 2020 | Chinese Journal of Integrative Medicine2020，26，3： | 11 |

| 16 | Crustal accretion and reworking processes of micro-continental massifs within orogenic belt:A case study of the Erguna Massif,NE China显示文摘This paper summarizes the geochronological, geochemical and zircon Hf isotopic data for Mesozoic granitoids within the Erguna Massif, NE China, and discusses the spatial-temporal variation of zircon Hf isotopic compositions, with the aim of constraining the accretion and reworking processes of continental crust within the Erguna Massif, and shedding light on the crustal evolution of the eastern segment of the Central Asian Orogenic Belt. Based on the zircon U-Pb dating results, the Mesozoic granitic magmatisms within the Erguna Massif can be subdivided into five stages: Early-Middle Triassic(249–237 Ma), Late Triassic(229–201 Ma), Early-Middle Jurassic(199–171 Ma), Late Jurassic(155–149 Ma), and Early Cretaceous(145–125 Ma).The Triassic to Early-Middle Jurassic granitoids are mainly I-type granites and minor adakitic rocks, whereas the Late Jurassic to Early Cretaceous granitoids are mainly A-type granites. This change in magmatism is consistent with the southward subduction of the Mongol-Okhotsk oceanic plate and subsequent collision and crustal thickening, followed by post-collision extension. Zircon Hf isotopic data indicate that crustal accretion of the Erguna Massif occurred in the Mesoproterozoic and Neoproterozoic. ZirconεHf(t) values increase gradually over time, whereas two-stage model(TDM2) ages decrease throughout the Mesozoic. The latter result indicates a change in the source of granitic magmas from the melting of ancient crust to more juvenile crust. Zircon εHf(t)values also exhibit spatial variations, with values decreasing northwards, whereas TDM2 ages increase. This pattern suggests that,moving from south to north, there is an increasing component of ancient crustal material within the lower continental crust of the Erguna Massif. Even if at the same latitude, the zircon Hf isotopic compositions are also inconsistent. These results reveal lateral and vertical heterogeneities in the lower continental crust of the Erguna Massif during the Mesozoic, which we use as the basis of a structural and tectonic model for this region. | SUN ChenYang TANG Jie XU WenLiang LI Yu ZHAO Shuo | 2017 | Science China Earth Sciences2017，60，7： | 10 |
| 17 | Multilocular Cystic Renal Cell Carcinoma:A Series of 8 Cases and Review of the Literature显示文摘OBJECTIVE To study the clinical,pathologic and imaging features of multilocular cystic renal cell carcinoma(MCRCC)and to review the diagnosis and treatment of this subtype of renal cell carcinoma(RCC). METHODS The data from 8 cases(mean age,49.4;5 men and 3 women) who had been treated from 2004 to 2006,were reviewed retrospectively. Radiologic and pathologic documents were evaluated.For treatments,radi- cal nephrectomy was conducted in 4 patients,partial nephrectomy in 2 and laparoscopic nephrectomy in 2. RESULTS Postoperative pathological findings confirmed the diagnosis of MCRCC.The stage of al 8 cases was pT1.For pathologic grade,7 cases were G1 and 1 case was G2.Seven patients available for follow-up had sur- vived tumor-free during the mean time of 8 months. CONCLUSION MCRCC is an uncommon subtype of RCC,it has a lower malignant potential and a better prognosis compared with other types of RCC.Nephron-sparing surgery may be an appropriate treatment options for MCRCC. | Shuo Liu Guang Sun Zhanjun Guo Xiaodong Li | 2007 | Chinese Journal of Clinical Oncology2007，4，2： | 9 |
| 18 | Physicochemical analysis of individual atmospheric fine particles based on effective surface-enhanced Raman spectroscopy显示文摘Fine particles associated with haze pollution threaten the health of more than 400 million people in China. It is therefore of great importance to thoroughly investigate and understand their composition. To determine the physicochemical properties in atmospheric fine particles at the micrometer level, we described a sensitive and feasible surface-enhanced Raman scattering(SERS) method using Ag foil as a substrate. This novel method enhanced the Raman signal intensities up to 10,000 a.u. for ν(NO_3^-) in fine particles.The SERS effect of Ag foil was further studied experimentally and theoretically and found to have an enhancement factor of the order of ~10~4. Size-fractionated real particle samples with aerodynamic diameters of 0.4–2.5 μm were successfully collected on a heavy haze day,allowing ready observation of morphology and identification of chemical components, such as soot, nitrates, and sulfates. These results suggest that the Ag-foil-based SERS technique can be effectively used to determine the microscopic characteristics of individual fine particles, which will help to understand haze formation mechanisms and formulate governance policies. | Zhenli Sun Fengkui Duan Kebin He Jingjing Du Liu Yang Hui Li Tao Ma Shuo Yang | 2019 | Journal of Environmental Sciences2019，31，1： | 9 |
| 19 | PPC-based Reactive Hot Melt Polyurethane Adhesive(RHMPA)--Efficient Glues for Multiple Types of Substrates显示文摘Tens of billion metric tons of anthropogenic CO_2 discharged from the burning of fossil fuels lead to an enormous environmental and resource burden. It is charming to transform CO_2 to desirable, economical chemicals and materials. Poly(propylene carbonate)(PPC) is an emerging CO_2-based material. Herein, we report the design, synthesis and characterization of the reactive hot melt polyurethane adhesive(RHMPA) based on PPC polyol. The resultant RHMPAs exhibit good adhesion properties to multiple substrates including plastics(PC, PMMA, ABS) and metals(aluminium, steel), which is comparable to or even better than conventional RHMPAs prepared from petro-based polyol. Furthermore, the PPC-based RHMPAs have tunable mechanical properties, and are thermally stable in the typical working range of bonding process(up to 270 °C). The study is expected to expand the applications of PPC and provide a new type of CO_2-based renewable and eco-friendly materials. | Zeng-He Liu Ji-Qing Huang Li-Jie Sun Dong Lei Jing Cao Shuo Chen Wen-Chang Shih Feng-Ling Qing Zheng-Wei You | 2018 | Chinese Journal of Polymer Science2018，36，1： | 7 |
| 20 | MmNet:Identifying Mikania micrantha Kunth in the wild via a deep Convolutional Neural Network显示文摘Mikania micrantha Kunth is an invasive alien weed and known as a plant killer around the world.Accurately and rapidly identifying M.micrantha in the wild is important for monitoring its growth status,as this helps management officials to take the necessary steps to devise a comprehensive strategy to control the invasive weed in the identified area.However,this approach still mainly depends on satellite remote sensing and manual inspection.The cost is high and the accuracy rate and efficiency are low.We acquired color images of the monitoring area in the wild environment using an Unmanned Aerial Vehicle(UAV)and proposed a novel network-MmNet-based on a deep Convolutional Neural Network(CNN)to identify M.micrantha in the images.The network consists of AlexNet Local Response Normalization(LRN),along with the GoogLeNet and continuous convolution of VGG inception models.After training and testing,the identification of 400 testing samples by MmNet is very good,with accuracy of 94.50%and time cost of 10.369 s.Moreover,in quantitative comparative analysis,the proposed MmNet not only has high accuracy and efficiency but also simple construction and outstanding repeatability.Compared with recently popular CNNs,MmNet is more suitable for the identification of M.micrantha in the wild.However,to meet the challenge of wild environments,more M.micrantha images need to be acquired for MmNet training.In addition,the classification labels need to be sorted in more detail.Altogether,this research provides some theoretical and scientific basis for the development of intelligent monitoring and early warning systems for M.micrantha and other invasive species. | QIAO Xi LI Yan-zhou SU Guang-yuan TIAN Hong-kun ZHANG Shuo SUN Zhong-yu YANG Long WAN Fang-hao QIAN Wan-qiang | 2020 | Journal of Integrative Agriculture2020，19，5： | 7 |
