1Corrosion Resistance of Graphene-Reinforced Waterborne Epoxy Coatings显示文摘Graphene(G) was dispersed uniformly in water and used as an inhibitor in waterborne epoxy coatings.The effect of dispersed G on anticorrosion performance of epoxy coatings was evaluated.The composite coatings displayed outstanding barrier properties against H_2O molecule compared to the neat epoxy coating.Open circuit potential(OCP),Tafel and electrochemical impedance spectroscopy(EIS)analysis con-?rmed that the corrosion rate exhibited by composite coatings with 0.5 wt%G was an order of magnitude lower than that of neat epoxy coating.Salt spray test results revealed superior corrosion resistance offered by the composite coating.Shuan Liu Lin Gu Haichao Zhao Jianmin Chen Haibin Yu 2016Journal of Materials Science & Technology2016,32,5:67
2Multiple genetic alterations and behavior of cellular biology in gastric cancer and other gastric mucosal lesions:H.pylori infection,histological types and staging显示文摘AIM To investigate the expression of multiplegenes and the behavior of cellular biology ingastric cancer(GC)and other gastric mucosallesions and their relations to Helicobacter pylori(H.pylori)infection,tumor staging andhistological subtypes.METHODS Three hundred and twenty-sevenspecimens of gastric mucosa obtained viaendoscopy or surgical resection,and ABCimmunohistochemical staining were used todetect the expression of p53,p16,Bcl-2 andCOX-2 proteins.H.pylori was determined byrapid urea test combined with pathologicalstaining or14C urea breath test.Cellular image analysis was performed in 66 patients withintestinal metaplasia(IM)and/or dysplasia(Dys).In 30 of them,both cancer and theparacancerous tissues were obtained at the timeof surgery.Histological pattern,tumor staging,lymph node metastasis,grading ofdifferentiation and other clinical data werestudied in the medical records.RESULTS p16 expression of IM or Dys wassignificantly lower in positive H.pylori chronicatrophic gastritis(CAG)than those withnegative H.pylori(CAG:54.8% vs 88.0%,IM:34.4% vs 69.6%,Dys:23.8% vs 53.6%,allP<0.05),Bcl-2 or COX-2 expression of IM orDys in positive H.pylori cases was significantlyhigher than that without H.pylori(Bcl-2:68.8%vs23.9%,90.5% vs 60.7%;COX-2:50.0% vs10.8%,61.8% vs 17.8%;all P<0.05).Themean number of most parameters of cellularimage analysis in positive H.pylori group wassignificantly higher than that in negative H.pylori group(Ellipser:53±14,40±12μm,Area1:748±572,302±202 μm2,Area2:3050±1661,1681±1990 μm2,all P<0.05;Ellipseb:79±23,58±15 μm,Ratio1:22%±5%,13%±4%,Ratio2:79%±17%,53%±20%,all P<0.01).There was significant correlation between Bcl-2and histologic pattern of gastric carcinoma,andbetween COX-2 and tumor staging or lymph nodemetastasis(Bcl-2:75.0% vs 16.7%;COX-2:76.0% vs 20.0%,79.2% vs 16.7%;allP<0.05).CONCLUSION p1l6, Bcl-2, and COX-2 but not p53 gene may play a role in the early genesis/ progression of gastric carcinoma and are associated with H. pylori infection. p53 gene is relatively late event in gastric tumorigenesis and mainly relates to its progression. There is more cellular-biological behavior of malignant tumor in gastric mucosal lesions with H. pylori infection. Aberrant Bcl-2 protein expression appears to be preferentially associated with the intestinal type cancer. COX-2 seems to be related to tumor staging and lymph node metastasis.Heng Jun Gao Lian Zhen Yu Jian Feng Bai Yan Shen Peng Gu Sun Han Lin Zhao Kun Miu Xiu Zhen Lü Xiao Yong Zhang Zhi Quan Zhao 2000World Journal of Gastroenterology2000,6,6:52

4Controlling N-doping type in carbon to boost single-atom site Cu catalyzed transfer hydrogenation of quinoline显示文摘Single-atom site(SA)catalysts on N-doped carbon(CN)materials exhibit prominent performance for their active sites being M-Nx.Due to the commonly random doping behaviors of N species in these CN,it is a tough issue to finely regulate their doping types and clarify their effect on the catalytic property of such catalysts.Herein,we report that the N-doping type in CN can be dominated as pyrrolic-N and pyridinic-N respectively through compounding with different metal oxides.It is found that the proportion of distinct doped N species in CN depends on the acidity and basicity of compounded metal oxide host.Owing to the coordination by pyrrolic-N,the SA Cu catalyst displays an enhanced activity(two-fold)for transfer hydrogenation of quinoline to access the valuable molecule tetrahydroquinoline with a good selectivity(99%)under mild conditions.The higher electron density of SA Cu species induced by the predominate pyrrolic-N coordination benefits the hydrogen transfer process and reduces the energy barrier of the hydrogenation pathway,which accounts for the improved catalytic effeciency.Jian Zhang Caiyan Zheng Maolin Zhang Yajun Qiu Qi Xu Weng-Chon Cheong Wenxing Chen Lirong Zheng Lin Gu Zhengpeng Hu Dingsheng Wang Yadong Li 2020Nano Research2020,13,11:29
5Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy.Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen 2021Cancer Communications2021,41,11:29

7The antitumor effect of tanshinone IIA on antiproliferation and decreasing VEGF/VEGFR2 expression on the human non-small cell lung cancer A549 cell line显示文摘The effects of tanshinone IIA on the proliferation of the human non-small cell lung cancer cell line A549 and its possible mechanism on the VEGF/VEGFR signal pathway were investigated.The exploration of the interaction between tanshinone IIA and its target proteins provides a feasible platform for studying the anticancer mechanism of active components of herbs.The CCK-8 assay was used to evaluate the proliferative activity of A549 cells treated with tanshinone IIA(2.5 80 μmol/L) for 24,48 and 72 h,respectively.Flow cytometry was used for the detection of cell apoptosis and cell cycle perturbation.VEGF and VEGFR2 expression were studied by Western blotting.The binding mode of tanshinone IIA within thecrystal structure of the VEGFR2 protein was evaluated with molecular docking analysis by use of the CDOCKER algorithm in Discovery Studio 2.1.The CCK-8 results showed that tanshinone IIA can significantly inhibit A549 cell proliferation in a dose-and time-dependent manner.Flow cytometry results showed that the apoptosis rate of tested group was higher than the vehicle control,and tanshinone IIAtreated cells accumulated at the S phase,which was higher than the vehicle control.Furthermore,the expression of VEGF and VEGFR2 was decreased in Western blot.Finally,molecular docking analysis revealed that tanshinone IIA could be stably docked into the kinase domain of VEGFR2 protein with its unique modes to form H-bonds with Cys917 and π–π stacking interactions with Val848.In conclusion,tanshinone IIA may suppress A549 proliferation,induce apoptosis and cell cycle arrest at the S phase.This drug may suppress angiogenesis by targeting the protein kinase domains of VEGF/VEGFR2.Jun Xie Jiahui Liu Heng Liu Shihui Liang Meigui Lin Yueyu Gu Taoli Liu Dongmei Wang Hui Gee Sui-lin Mo 2015Acta Pharmaceutica Sinica B2015,5,6:26
8Metallogenesis related to Mesozoic Granitoids in the Nanling Range, South China and Their Geodynamic Settings显示文摘Affected by the compressive stress from the South-Central (Indo-China) Peninsula, the Indosinianorogenesis, characterized by collision, thrust and uplifting, took place inside the South China Plate during 250?230 Ma.The ages of the Indosinian granitoids in the Nanling Range and vicinity areas are mostly 240?205 Ma, indicating that theywere emplaced in both late collision and post-collision geodynamic environments. No important granite-relatedmetallogenesis occurred in this duration. A post-orogenic setting started at the beginning of the Yanshanian Period, whichcontrolled large-scale granitic magmatism and related metallogenesis. This paper makes the first attempt to divide theYanshanian Period into three sub-periods, i.e. the early, middle and late Yanshanian Periods, based mainly on the featuresof magmatism, especially granitoids and related metallogenesis and their geodynamic environments. The magmaticassociation of the Early Yanshanian (about 185?170 Ma) comprises four categories of magmatism, i.e. basalt, bimodalvolcanics, A-type granite and intraplate high-K calc-alkaline (HKCA) magmatism, which indicates an extension-thinningof lithosphere and upwelling of mantle material to a relative small and local extent. Pb-Zn, Cu and Au mineralizationsassociated with HKCA magmatism represents the first high tide of Mesozoic metallogenesis in the Nanling Range area.During the middle Yanshanian, the lithosphere was subjected to more extensive and intensive extending and thinning, andhence mantle upwelling and basaltic magma underplating caused a great amount of crust remelting granitoids. This periodcan be further divided into two stages. The first stage (170?150 Ma) is represented by large-scale emplacement of crustremelting granites with local tungsten mineralization at its end. The second stage (150?140 Ma) is the most important timeof large-scale mineralizations of non-ferrous and rare metals, e.g. W, Sn, Nb-Ta, Bi, Mo, Be, in the Nanling Range area.The late Yanshanian (140?65 Ma) was generally characterized by full extension and breakup of the lithosphere of SouthChina. However, owing to the influence of the Pacific Plate movement, the eastern part of South China was predominatedby subduction-related compression, which resulted in magmatism of calc-alkaline and shoshonite series and relatedmetallogeneses of Au, Ag, Pb-Zn, Cu and (Mo, Sn), followed by extension in its late stage. In the Nanling Range area, thelate Yanshanian magmatism was represented by granitic volcanic-intrusive complexes and mafic dikes, which aregenetically related to volcanic-type uranium and porphyry tin deposits, and the mobilization-mineralization of uraniumfrom pre-existing Indosinian granites.HUA Renmin CHEN Peirong ZHANG Wenlan YAO Junming LIN Jinfu ZHANG Zhanshi GU Shengyan LIU Xiaodong QI Huawen 2005Acta Geologica Sinica(English Edition)2005,79,6:22

16Advanced Space-based Solar Observatory(ASO-S):an overview显示文摘The Advanced Space-based Solar Observatory(ASO-S)is a mission proposed for the 25 th solar maximum by the Chinese solar community.The scientific objectives are to study the relationships between the solar magnetic field,solar flares and coronal mass ejections(CMEs).Three payloads are deployed:the Full-disk vector Magneto Graph(FMG),the Lyman-αSolar Telescope(LST)and the Hard X-ray Imager(HXI).ASO-S will perform the first simultaneous observations of the photospheric vector magnetic field,non-thermal imaging of solar flares,and the initiation and early propagation of CMEs on a single platform.ASO-S is scheduled to be launched into a 720 km Sun-synchronous orbit in 2022.This paper presents an overview of the mission till the end of Phase-B and the beginning of Phase-C.Wei-Qun Gan Cheng Zhu Yuan-Yong Deng Hui Li Yang Su Hai-Ying Zhang Bo Chen Zhe Zhang Jian Wu Lei Deng Yu Huang Jian-Feng Yang Ji-Jun Cui Jin Chang Chi Wang Ji Wu Zeng-Shan Yin Wen Chen Cheng Fang Yi-Hua Yan Jun Lin Wei-Ming Xiong Bin Chen Hai-Chao Bao Cai-Xia Cao Yan-Ping Bai Tao Wang Bing-Long Chen Xin-Yu Li Ye Zhang Li Feng Jiang-Tao Su Ying Li Wei Chen You-Ping Li Ying-Na Su Hai-Yan Wu Mei Gu Lei Huang Xue-Jun Tang 2019Research in Astronomy and Astrophysics2019,19,11:17
17Single whispering-gallery mode lasing in polymer bottle microresonators via spatial pump engineering显示文摘Single-mode lasing in whispering-gallery mode(WGM)microresonators is challenging to achieve.In bottle microresonators,the highly non-degenerated WGMs are spatially well-separated along the long-axis direction and provide mode-selection capability.In this work,by engineering the pump intensity to modify the spatial gain profiles of bottle microresonators,we demonstrate a simple and general approach to realizing single-mode WGM lasing in polymer bottle microresonators.The pump intensity is engineered into an interference distribution on the bottle microresonator surface.By tuning the spacing between axial positions of the interference pump patterns,the mode intensity profiles of single-bottle WGMs can be spatially overlapped with the interference stripes,intrinsically enabling single-mode lasing and selection.Attractive advantages of the system,including high sidemode suppression factors 420 dB,large spectral tunability 48 nm,low-lasing threshold and reversible control,are presented.Our demonstrated approach may have a variety of promising applications,ranging from tunable single-mode lasing and sensing to nonlinear optics.Fuxing Gu Fuming Xie Xing Lin Shuangyi Linghu Wei Fang Heping Zeng Limin Tong Songlin Zhuang 2017Light(Science & Applications)2017,6,1:17
18Incidence trends and age distribution of colorectal cancer by subsite in Guangzhou,2000-2011显示文摘Introduction:Colorectal cancer(CRC) is the third most common cancer in China.The incidence of CRC has been increasing in recent years.The aim of this study was to explore the incidence trends and the age distribution of CRC by subsite in Guangzhou between 2000 and 2011.Methods:A total of 22,432 incident cases of CRC between 2000 and 2011 from Guangzhou Cancer Registry were identified.Crude incidence and age-standardized rates(ASRs),using the Segi’s world standard population,were calculated for CRC and CRC subsites.The incidence trend was analyzed and the annual percentage change(APC) in incidence was calculated by using JoinPoint software.Results:The crude incidence increased significantly from 23.4/10~5 in 2000 to 37.4/10~5 in 2011 for males and from20.9/10~5 to 30.5/10~5 for females.The ASRs of CRC incidence stabilized during the period of 2000-2011 for both males and females.The ages at the onset of CRC for both males and females during 2010-2011 were significantly higher compared with those during 2000-2002(males:f = 1.95,P = 0.05;females:f = 6.03,P < 0.01).For males aged50-64 years,the CRC incidence increased by 8.50%annually(P = 0.04) during 2000-2004 and by 1.68%annually(P = 0.03) during 2005-2011.For females aged 65 years and older,the CRC incidence increased by 5.77%annually(P = 0.03) during 2000-2004.There were no significant changes for the CRC incidences in males aged 49 and younger and 65 years and older and females aged 64 years and younger during 2000-2004,or for those in all females as well as males aged 49 years and younger and 65 years and older during 2005-2011.The percentage of colon cancer in all CRCs increased significantly for both males and females between the periods of 2000-2002 and 2010-2011.The ASRs of descending colon and sigmoid colon cancer incidences increased significantly for females during 2005-2011(APC,5.51%and 1.08%,respectively,both P < 0.05).Conclusions:The crude incidence of CRC increased significantly between 2000 and 2011 because of the aging,whereas the ASRs kept stable.The percentage of colon cancer in all CRCs increased significantly.Further surveillance,research,and intervention are needed to identify the causes of these changes and to reduce the incidence and mortality of CRC.Qin Zhou Ke Li Guo-Zhen Lin Ji-Chuan Shen Hang Dong Yu-Ting Gu Hua-Zhang Liu 2015Chinese Journal of Cancer2015,34,8:17
