| 1 | Carcinogenic potential of duodenal reflux juice from patients with long-standing postgastrectomy显示文摘AIM To determine, whether study on thecarcinogenic potential of reflux juice frompatients with remote gastrectomy could clarifythe inherent relationship between duodenalreflux and gastric stump cancer.METHODS A total of 37 reflux juice samples(13 Billroth T, 24 Billroth Ⅱ ) were employed inthe present study. A two- stage transformationassay using BALB/c 3T3 cells was carried out totest the initiating or promoting activity of thesesamples.RESULTS Two of 18 (11.1%) reflux samplesexerted initiating activities, whereas 9/19(47.4%) samples enhanced the MNNG-initiafingcell transformation, suggesting the duodenalreflux juice might more frequently possess thetumor-promoter activity (P = 0. 029). In addition,there was no difference in initiating activities ofthe samples irrespective of surgical procedures(P=0.488), while Billroth Ⅱ samples exhibitedstronger tumor-promoter activity than Billroth Ⅰsamples (P = 0.027). Furthermore, the promoteractivities were well correlated with thehistological changes of the stomas (rs = 0.625,P = 0.004), but neither their cytotoxicities norinitiating activities had this correlation( Probabilities were 0.523 and 0.085,respectively).CONCLUSION The duodenal reflux juice frompatients with remote postgastrectomy did havecarcinogenic potential, and suggested thattumor-promoting activity should principallyaccount for the high incidence of gastric cancerin gastrectomy patients. In contrast, it isdifficult to explain the high stump-cancerincidence with the 'N-nitroso compounds'theory-a popular theory for the intact stomachcarcinogenesis, and it seemed to be justified tofocus chemoprevention of this cancer on thetumor-promoting potential of reflux juice. | Zhe Fu Ma~1 Zhong Yu Wang~1 Jun Ran Zhang~2 Peng Gong~1 Hai Long Chen~1 ~1Departrnent of General Surgery,First Hospital,Dalian Medical University,Dalian 116011,China ~2Department of Radiation Oncology,Massachusetts General Hospital and Harvard Medical School,Charlestown,MA 02129,USADr.Zhe Fu Ma graduated from Shanxi Medical College in 1993,nowPh.D.,M.D.in Department of Surgery,Dalian Medical University,majoring gastroenteric cancer,having 4 papers published.Correspondence to:Dr.Zhe Fu Ma.Department of General Surgery,First Hospital,Dalian Medical University,Dalian 116011,China Tel.0086-411-4720334 | 2001 | World Journal of Gastroenterology2001，7，3： | 9 |

| 3 | Seasonal variation of nitrogen and phosphorus in Xiaojiang River-A tributary of the Three Gorges Reservoir显示文摘A yearlong monitoring program in the backwater area of Xiaojiang River(XBA)was launched in order to investigate the eutrophication of backwater areas in tributaries of the Yangtze River in the Three Gorges Reservoir(TGR)in China,starting after the impoundment water level of the TGR reached 156 m.From March 2007 to March 2008,the average concentration of total nitrogen(TN)and total phosphorus(TP)were(1553484)μg·L^(–1)and(6231)μg·L^(–1),respectively.The mean value of chlorophyll was(9.070.91)μg·L^(–1).The trophic level of XBA was meso-eutrophic,while the general nutrient limitation was phosphorus.The results indicated that XBA has a strong ability to purify itself and has non-point source pollution from terrestrial runoff.The variation of TN/TP ratio was caused by a variation in TN rather than in TP when TN/TP<22.N-fixation from cyanobacteria occurred and became an important process in overcoming the nitrogen deficit under a low TN/TP ratio.When TN/TP≥22,the variation of TP affected the TN/TP ratio more significantly than TN.The increase of TP in XBA was caused mainly by particulate phosphorus,which could originate from a non-point source as adsorptive inorganic forms after heavy rainfall and surface runoff.An increase in the river’s flow could also contribute to an unstable environment for the growth of phytoplankton. | Zhe LI Jinsong GUO Man LONG Fang FANG Jinping SHENG Hong ZHOU | 2009 | Frontiers of Environmental Science & Engineering2009，3，3： | 8 |
| 4 | microRNA-218 suppresses the proliferation, invasion and promotes apoptosis of pancreatic cancer cells by targeting HMGB1显示文摘Objective: To detect the expression profiles of micro RNA-218(mi R-218) in human pancreatic cancer tissue(PCT) and cells and their effects on the biological features of human pancreatic cancer cell line PANC-1 and observe the effect of mi R-218 on the expression of the target gene high mobility group box 1(HMGB1), with an attempt to provide new treatment methods and strategies for pancreatic cancer.Methods: The expressions of mi R-218 in PCT and normal pancreas tissue as well as in various pancreatic cancer cell lines including As PC-1, Bx PC-3, and PANC-1 were determined with quantitative real-time reverse transcription polymerase chain reaction(q RT-PCR). The change of mi R-218 expression in PANC-1 cells was detected using qR T-PCT after the transfection of miR-218 mimic for 48 h. Cell Counting Kit-8(CCK-8) was applied for detecting the effect of mi R-218 on the activity of PANC-1 cells. The effects of mi R-218 on the proliferation and apoptosis of PANC-1 cells were analyzed using the flow cytometry. The effect of mi R-218 on the migration of PANC-1 cells was detected using the Trans-well migration assay. The HMGB1 was found to be a target gene of mi R-218 by luciferase reporter assay, and the effect of mi R-218 on the expression of HMGB1 protein in cells were determined using Western blotting.Results: As shown by q RT-PCR, the expressions of mi R-218 in PCT and in pancreatic cancer cell line significantly decreased when compared with the normal pancreatic tissue(NPT)(P<0.01). Compared with the control group, the miR-218 expression significantly increased in the PANC-1 group after the transfection of mi R-218 mimic for 48 h(P<0.01). Growth curve showed that the cell viability significantly dropped after the overexpression of mi R-218 in the PANC-1 cells for two days(P<0.05). Flow cytometry showed that the S-phase fraction significantly dropped after the overexpression of mi R-218(P<0.01) and the percentage of apoptotic cells significantly increased(P<0.01). As shown by the Trans-well migration assay, the enhanced mi R-218 expression was associated with a significantly lower number of cells that passed through a Transwell chamber(P<0.01). Luciferase reporter assay showed that, compared with the control group, the relative luciferase activity significantly decreased in the mi R-218 mimic group(P<0.01). As shown by the Western blotting, compared with the control group, the HMGB1 protein expression significantly decreased in the PANC-1 group after the transfection of mi R-218 mimic for 48 h(P<0.01).Conclusions: The mi R-218 expression decreases in human PCT and cell lines. mi R-218 can negatively regulate the HMGB1 protein expression and inhibit the proliferation and invasion of pancreatic cancer cells. A treatment strategy by enhancing the mi R-218 expression may benefit the patients with pancreatic cancer. | Zhe Liu Yuanhong Xu Jin Long Kejian Guo Chunlin Ge Ruixia Du | 2015 | Chinese Journal of Cancer Research2015，27，3： | 7 |
| 5 | Effect of tin addition on corrosion behavior of a low-alloy steel in simulated costal-industrial atmosphere显示文摘The effect of tin addition on the atmospheric corrosion behavior of a low-alloy steel in sim ulated coastalindustrial atm osphere has been investigated by indoor wet/dry cyclic corrosion test (CCT). The results indicate that tin addition can obviously make the steel substrate more resistant to atmospheric corrosion by suppressing the cathodic H^+ reduction reaction, and but tin addition is not of obvious beneficial effect when the steel is covered with a thicker rust layer during long-term corrosion process. The reason lies in the fact that the presence of un-reduced H^+ can lower the electrolyte pH value and lead to a loose and porous rust layer on tin-containing steel sample than that on tin-free steel sample. In addition, the 120 CCT cycles corrosion process of the two steels can be divided into three stages. Both the tin-free and tin-containing steels show an increasing corrosion rate during the initial corrosion stage and then exhibit a decreasing corrosion rate during the second and third corrosion stages. Moreover, tin addition makes the tin-containing steel rust layer have a higher amount of α-FeOOH and lower am ount of γ-FeOOH and Fe3O4 than the tin-free steel rust layer. | Bo Liu Xin Mu Ying Yang Long Hao Xueyong Ding Junhua Dong Zhe Zhang Huaxing Hou Wei Ke | 2019 | Journal of Materials Science & Technology2019，35，7： | 6 |
| 6 | Desertification: China provides a solution to a global challenge显示文摘Desertification has been caused by various factors and is a major environmental problem and development bottleneck faced by the world. It is also a serious threat to ecological security and to sustainable economic and social development. As a stubborn world problem, focused on by the United Nations 2030 sustainable development goal 15.3, China aims to combat desertification by implementing the 'eight-column fourbeam' strategy, and also suggest the 'four-medicine'approach for global desertification governance. This includes the development of the United Nations Convention to Combat Desertification protocol, unified global compliance and compliance metrics; building a global observation network, and monitoring land changes based on remote sense; preparing the global natural desert(heritage) list, leaving the original deserts for future generations; initiating the global action of combating desertification, and striving to achieve a land degradationneutral world by 2030. | Yingshuang BAO Leilei CHENG Yanfeng BAO Liu YANG Lina JIANG Chao LONG Zhe KONG Peng PENG Jun XIAO Qi LU | 2017 | Frontiers of Agricultural Science and Engineering2017，4，4： | 3 |
| 7 | BMI and BMI Changes to All-cause Mortality among the Elderly in Beijing: a 20-year Cohort Study显示文摘Objective To explore the association between body mass index(BMI)and all-cause mortality among the elderly in Beijing.Methods This analysis was based on the Beijing multidimensional longitudinal study of aging(BLSA),which included 2,090 subjects over 55 years old and was followed-up from 1992 to 2012.BMI-mortality curves were drawn to find the optimal BMI range with the lowest mortality.Cox proportional hazard models were used to obtain the hazard ratios(HRs)for BMI and BMI changes in the overall population and in specific stratified populations.Results During follow-up,1,164 deaths were recorded;BMI-mortality curve was U-shaped,with the lowest mortality at a BMI of approximately 25 kg/m^2.After adjusting for gender,age,smoking,drinking and some pre-existing diseases,HRs for underweight,overweight and obesity compared with normal weight were 1.372(95%CI:1.154-1.631),0.767(95%CI:0.666-0.884)and 0.871(95%CI:0.830-1.246),respectively.HR for BMI drop was 3.245(95%CI:0.824-12.772)in the underweight group and 1.892(95%CI:0.830-1.246)in the normal weight group,HR for BMI rise was 1.795(95%CI:1.243-2.591)in normal weight group and 1.962(95%CI:1.202-3.203)in the overweight group.Conclusion Keeping BMI in an overweight status and stable is related to a reduced mortality. | WANG Yun Feng TANG Zhe GUO Jin TAO Li Xin LIU Long LI Hai Bin LI Di Tian GUO Xiu Hua YANG Xing Hua | 2017 | Biomedical and Environmental Sciences2017，30，2： | 3 |
| 8 | Supergravity separation of Pb and Sn from waste printed circuit boards at different temperatures显示文摘Printed circuit boards(PCBs) contain many toxic substances as well as valuable metals, e.g., lead(Pb) and tin(Sn). In this study, a novel technology, named supergravity, was used to separate different mass ratios of Pb and Sn from Pb–Sn alloys in PCBs. In a supergravity field, the liquid metal phase can permeate from solid particles. Hence, temperatures of 200, 280, and 400°C were chosen to separate Pb and Sn from PCBs. The results depicted that gravity coefficient only affected the recovery rates of Pb and Sn, whereas it had little effect on the mass ratios of Pb and Sn in the obtained alloys. With an increase in gravity coefficient, the recovery values of Pb and Sn in each step of the separation process increased. In the single-step separation process, the mass ratios of Pb and Sn in Pb–Sn alloys were 0.55, 0.40, and 0.64 at 200, 280, and 400°C, respectively. In the two-step separation process, the mass ratios were 0.12 and 0.55 at 280 and 400°C, respectively. Further, the mass ratio was observed to be 0.76 at 400°C in the three-step separation process. This process provides an innovative approach to the recycling mechanism of Pb and Sn from PCBs. | Long Meng Zhe Wang Yi-wei Zhong Kui-yuan Chen Zhan-cheng Guo | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，2： | 3 |
| 9 | Single-End Adaptive Optics Compensation for Emulated Turbulence in a Bi-Directional 10-Mbit/s per Channel Free-Space Quantum Communication Link Using Orbital-Angular-Momentum Encoding显示文摘A single-end adaptive-optics(AO)module is experimentally demonstrated to mitigate the emulated atmospheric turbulence efects in a bi-directional quantum communication link,which employs orbital angular momentum(OAM)for data encoding.A classical Gaussian beam is used as a probe to detect the turbulence-induced wavefront distortion in the forward direction of the link.Based on the detected wavefront distortion,an AO system located on one end of the link is used to simultaneously compensate for the forward and backward channels.Specifcally,with emulated turbulence and when the probe is turned on,the mode purity of photons carrying OAMℓ=1 is improved by∼21%with AO mitigation.We also measured the performance when encoding data using OAM{ℓ=−1,+2}and{ℓ=−2,+1}in the forward and backward channels,respectively,at 10 Mbit/s per channel with one photon per pulse on average.For this case,we found that the AO system could reduce the turbulence efects increased quantum-symbolerror-rate(QSER)by∼76%and∼74%,for both channels in the uni-directional and bi-directional cases,respectively.Similar QSER improvement is observed for the opposite direction channels in the bi-directional case. | Cong Liu Kai Pang Zhe Zhao Peicheng Liao Runzhou Zhang Haoqian Song Yinwen Cao Jing Du Long Li Hao Song Yongxiong Ren Guodong Xie Yifan Zhao Jiapeng Zhao Seyed M.H.Rafsanjani Ari N.Willner Jeffrey H.Shapiro Robert W.Boyd Moshe Tur Alan E.Willner | 2019 | Research2019，，1： | 3 |
| 10 | Genetic parameters and trends for production and reproduction traits of a Landrace herd in China显示文摘The objectives of this study were to estimate the genetic parameters and the breeding progress in a Landrace herd in China, and to predict the potential benefits by applying new breeding technology. Hereby, the performance records from a Landrace swine herd in China, composing over 33 000 pigs born between 2001 and 2013, were collected on six economically important traits, i.e., average daily gain between 30–100 kg(ADG), adjusted backfat thickness at 100 kg(BF), adjusted days to 30 kg(D30), adjusted days to 100 kg(D100), number born alive(NBA), and total number born(TNB). The genetic parameters were estimated by restricted maximum likelihood via DMU, and realized genetic trends were analyzed. Based on the real population structure and genetic parameters obtained from this herd, the potential genetic trends by applying genomic selection(GS) were predicted via a computer simulation study. Results showed that the heritability estimates in this Landrace herd were 0.55(0.02), 0.42(0.01), and 0.12(0.01), for BF, D100, and TNB, respectively. Favorable genetic trends were obtained for D100, BF, and TNB due to direct selection, for ADG and NBA due to indirect selection. Long-term selection against D100 did not improve D30, though they are highly genetically correlated(0.64). Appling GS in such a swine herd, the genetic gain can be increased by 25%, or even larger for traits with low heritability or individuals without phenotypes before selection. It can be concluded that conventional breeding strategy was effective in the herd studied, while applying GS is promising and hence the road ahead in swine breeding. | ZHANG Zhe ZHANG Hao PAN Rong-yang WU Long LI Ya-lan CHEN Zan-mou CAI Geng-yuan LI Jia-qi WU Zhen-fang | 2016 | Journal of Integrative Agriculture2016，15，5： | 3 |
| 11 | Enhancing bifunctionality of CoN nanowires by Mn doping for long-lasting Zn-air batteries显示文摘Tailoring the nanostructure and composition of transition metal nitrides is highly important for their use as potent low-cost electrocatalysts. Cobalt nitride(CoN) exhibits strong catalytic activity for oxygen evolution reaction(OER). However, its poor catalytic efficiency for oxygen reduction reaction(ORR) hinders its application in rechargeable zinc-air batteries(ZABs) as the air cathode. In this work, we deploy the effective strategy of Mn doping to improve both OER and ORR activity of CoN nanowires as the cathode material for ZAB. Theoretical calculation predicts that moderate Mn doping in cobalt nitride results in a downshift of the d-band center and reduces the adsorption energy of reaction intermediates. With ~10 at% Mn dopants, stronger catalysis activities for both OER and ORR are achieved compared to pure CoN nanowires. Subsequently, both aqueous and flexible quasi-solid-state ZABs are constructed using the Mn-doped CoN nanowires array as additive-free air cathode. Both types of devices present large open circuit potential, high power density and long-cycle stability. This work pushes forward the progress in developing cost-effective ZABs. | Yongqi Zhang Bo Ouyang Guankui Long Hua Tan Zhe Wang Zheng Zhang Weibo Gao Rajdeep Singh Rawat Hong Jin Fan | 2020 | Science China Chemistry2020，63，7： | 3 |
| 12 | Reliability Evaluation of Machine Center Components Based on Cascading Failure Analysis显示文摘In order to rectify the problems that the component reliability model exhibits deviation, and the evaluation result is low due to the overlook of failure propagation in traditional reliability evaluation of machine center components, a new reliability evaluation method based on cascading failure analysis and the failure influenced degree assessment is proposed. A direct graph model of cascading failure among components is established according to cascading failure mechanism analysis and graph theory. The failure influenced degrees of the system components are assessed by the adjacency matrix and its transposition, combined with the Pagerank algorithm.Based on the comprehensive failure probability function and total probability formula, the inherent failure probability function is determined to realize the reliability evaluation of the system components. Finally, the method is applied to a machine center, it shows the following: 1)The reliability evaluation values of the proposed method are at least 2.5% higher than those of the traditional method; 2) The difference between the comprehensive and inherent reliability of the system component presents a positive correlation with the failure influenced degree ofthe system component, which provides a theoretical basis for reliability allocation of machine center system. | Ying-Zhi Zhang Jin-Tong Liu Gui-Xiang Shen Zhe Long Shu-Guang Sun | 2017 | Chinese Journal of Mechanical Engineering2017，30，4： | 3 |

| 14 | Orbital-angular-momentum-based reconfigurable optical switching and routing显示文摘Orbital angular momentum(OAM) has gained interest due to its potential to increase capacity in optical communication systems as well as an additional domain for reconfigurable networks. This is due to the following:(i) coaxially propagated OAM beams with different charges are mutually orthogonal,(ii) OAM beams can be efficiently multiplexed and demultiplexed, and(iii) OAM charges can be efficiently manipulated. Therefore, multiple data-carrying OAM beams could have the potential capability for reconfigurable optical switching and routing. In this paper, we discuss work involving reconfigurable OAM-based optical add/drop multiplexing, space switching,polarization switching, channel hopping, and multicasting. | Alan E.Willner Long Li Guodong Xie Yongxiong Ren Hao Huang Yang Yue Nisar Ahmed Moshe J.Willner Asher J.Willner Yan Yan Zhe Zhao Zhe Wang Cong Liu Moshe Tur Solyman Ashrafi | 2016 | Photonics Research2016，4，5： | 2 |
| 15 | Superplastic deformation behavior of Mg alloys: A-review显示文摘The magnesium alloys are the next-generation lightweight metal materials;however, the production of the complex shape components of thermo-mechanical processed magnesium alloys is very limited in comparison to their die-casted counterparts. Both high strain rate and low-temperature processing are required to save time and cost for the project. Uniaxial tensile testing has been vastly used for determining the plasticity of magnesium alloys at elevated temperatures. Therefore, this review article sheds light on superplastic behaviors under the uniaxial tensile loading of different magnesium alloys. This review also emphasizes low and high-temperature superplasticity, high strain rate superplasticity, deformation mechanism, thermal stability, texture evaluation, and fracture mechanism of extruded/rolled and severe plastic deformed magnesium alloys. At the end of the review, some technical issues have been addressed which can be beneficial for further enhancement in the superplasticity of magnesium alloys. | Faisal Nazeer Jianyu Long Zhe Yang Chuan Li | 2022 | Journal of Magnesium and Alloys2022，10，1： | 2 |
| 16 | Iterative assist-as-needed control with interaction factor for rehabilitation robots显示文摘Rehabilitation robots for stroke patients have drawn considerable attention because they can reduce the economic and labor costs brought by traditional rehabilitation. Control methods for rehabilitation robots have been developed to stimulate the active motion of patients and to improve the effectiveness of rehabilitation care. However, current control methods can only roughly adjust the system’s stiffness and may fail in achieving satisfactory performance. To this end, this paper introduces a novel cost function consisting of the tracking error term and the stiffness term. The cost function contains an interaction factor that represents the patient’s motion intention to balance the weight of these two terms. When the patients try to actively do training tasks, the weight of stiffness term increases, which leads to the larger allowable tracking error and lower stiffness eventually. An iterative updating law of the stiffness matrix is given to reduce the proposed cost function. Theoretical analysis based on the Lyapunov theory is given to ensure the feasibility of the proposed algorithm. Furthermore, a force estimation is used to improve interaction control performance. Finally, simulation experiments are provided to show the effectiveness of the proposed algorithm. | CAO Ran CHENG Long YANG ChenGuang DONG Zhe | 2021 | Science China(Technological Sciences)2021，64，4： | 2 |
| 17 | microRNA-218 promotes gemcitabine sensitivity in human pancreatic cancer cells by regulating HMGB1 expression显示文摘Objective: The purpose of this study was to examine the effect of gemcitabine(GEM) on micro RNA-218(mi R-218) expression in human pancreatic cancer cells.Methods: Quantitative reverse transcription polymerase chain reaction(q RT-PCR) was performed to examine the differences in mi R-218 expression between the GEM-sensitive Bx PC-3 pancreatic cancer cells and GEM-resistant PANC-1 cells. The effect of GEM on the expression of mi R-218 in PANC-1 cells was also investigated. PANC-1 cells were transfected either with HMGB1 si RNA to knock down the expression of HMGB1 or with the recombinant HMGB1 expression vector(pc DNA3.1-HMGB1) to overexpress HMGB1. The effect of ectopic expression of HMGB1 on the apoptosis of mi R-218-transfected and GEMtreated PANC-1 cells was examined by flow cytometric analysis.Results: The mi R-218 expression level was lower in GEM-resistant PANC-1 cells compared to GEMsensitive Bx PC-3 cells(P<0.05). The percentage of apoptotic PANC-1 cells was significantly increased in the mi R-218 mimic + GEM group compared to the mimic ctrl + GEM group and the normal control group(P<0.01). The HMGB1 expression level was markedly decreased in PANC-1 cells transfected with HMGB1 si RNA but was significantly increased in PANC-1 cells transfected with the recombinant HMGB1 expression vector, pc DNA3.1-HMGB1(P<0.01). The proportion of apoptotic PANC-1 cells was significantly lower in the mi R-218 mimic + GEM + pc DNA3.1-HMGB1 group compared to the mi R-218 mimic + GEM + HMGB1 si RNA group(P<0.01).Conclusions: The expression level of mi R-218 was downregulated in the GEM-resistant cell line. mi R-218 promoted the sensitivity of PANC-1 cells to GEM, which was achieved mainly through regulating the expression of HMGB1 in PANC-1 cells. | Zhe Liu Ruixia Du Jin Long Kejian Guo Chunlin Ge Shulong Bi Yuanhong Xu | 2015 | Chinese Journal of Cancer Research2015，27，3： | 2 |
| 18 | Huge peripheral primitive neuroectodermal tumor of the small bowel mesentery at nonage:A case report and review of the literature显示文摘Extraskeletal Ewing's sarcoma/peripheral primitive neuroectodermal tumor(E-EWS/pP NET) is a rare aggressive malignant small round cell tumor. In this report, we present the case of a 15-year-old boy who suffered from acute abdominal pain accompanied by hematemesis and melena, and was eventually diagnosed with E-EWS/p PNET. To date, there have been only five reported cases of E-EWS/pP NET of the small bowel including the patient in this report. To the best of our knowledge, this is the first documentation of a pP NET of the small bowel mesentery at nonage. All these have made this report rare and significant. | Zhe Liu Yuan-Hong Xu Chun-Lin Ge Jin Long Rui-Xia Du Ke-Jian Guo | 2016 | World Journal of Clinical Cases2016，4，9： | 2 |
| 19 | Roles of furfural during the thermal treatment of bio-oil at low temperatures显示文摘The reactive O-containing species in bio-oil could induce the polymerization of bio-oil during its thermal treatment, which affects the relevant utilization of bio-oil significantly. Furans, as the highly reactive Ocontaining species in bio-oil, play important roles during the thermal treatment of bio-oil. In this study,furfural was chosen as the representative of the furans in bio-oil to investigate its roles during the thermal treatment of bio-oil. The raw bio-oil with and without the addition of extra furfural(10 wt% of bio-oil) and pure furfural were pyrolyzed in a fixed-bed reactor at 200–500 ℃. The results show that the interactions among furfural and bio-oil components can take place prior to the evaporation of furfural(<140 ℃) to form the intermediates, then these intermediates could be further polymerized to form large molecular compounds, and coke can be formed via the interactions at temperatures ≥ 300 ℃. At temperatures ≤ 300 ℃, furfural mainly interacts with anhydrosugars. As the temperature further increases, the aromatics are involved in the interactions to form coke. The increased percentage of the coke formed via the interactions is in a linear relation with the conversion of furfural during the pyrolysis at 300–500 ℃(no coke formed at 200 ℃). Meanwhile, more non-aromatic light components(≤ C6) and less aromatics in the tars could be formed due to the interactions. | Zhe Xiong Yuanjing Chen Muhammad Mufti Azis Xun Hu Wei Deng Hengda Han Long Jiang Sheng Su Song Hu Yi Wang Jun Xiang | 2020 | Journal of Energy Chemistry2020，29，11： | 2 |
| 20 | TRAF4 mediates activation of TGF-β signaling and is a biomarker for oncogenesis in breast cancer显示文摘The tumor-promoting arm of transforming growth factor beta(TGF-β)receptor signaling contributes to advanced cancer progression and is considered a master regulator of breast cancer metastasis.In mammals,there are six distinct members in the tumor-necrosis factor receptor(TNFR)-associated factor(TRAF)family(TRAF1–TRAF6),with the function of TRAF4 not being extensively studied in the past decade.Although numerous studies have suggested that there is elevated TRAF4 expression in human cancer,it is still unknown in which oncogenic pathway TRAF4 is mainly implicated.This review highlights TGF-β-induced SMAD-dependent signaling and non-SMAD signaling as the major pathways regulated by TRAF4 involved in breast cancer metastasis. | ZHOU Fang Fang LI Fang XIE Feng ZHANG Zheng Kui HUANG Hui Zhe ZHANG Long | 2014 | Science China(Life Sciences)2014，57，12： | 2 |
