| 1 | Land-atmosphere-ocean coupling associated with the Tibetan Plateau and its climate impacts显示文摘This paper reviews recent advances regarding land-atmosphere-ocean coupling associated with the Tibetan Plateau(TP)and its climatic impacts.Thermal forcing over the TP interacts strongly with that over the Iranian Plateau,forming a coupled heating system that elevates the tropopause,generates a monsoonal meridional circulation over South Asia and creates conditions of large-scale ascent favorable for Asian summer monsoon development.TP heating leads to intensification and westward extension(northward movement)of the South Asian High(Atlantic Intertropical Convergence Zone),and exerts strong impacts on upstream climate variations from North Atlantic to West Asia.It also affects oceanic circulation and buoyancy fields via atmospheric stationary wave trains and air-sea interaction processes,contributing to formation of the Atlantic Meridional Overturning Circulation.The TP thermal state and atmospheric-oceanic conditions are highly interactive and Asian summer monsoon variability is controlled synergistically by internal TP variability and external forcing factors. | Yimin Liu Mengmeng Lu Haijun Yang Anmin Duan Bian He Song Yang Guoxiong Wu | 2020 | National Science Review2020，7，3： | 21 |
| 2 | An individualized immune signature of pretreatment biopsies predicts pathological complete response to neoadjuvant chemoradiotherapy and outcomes in patients with esophageal squamous cell carcinoma显示文摘No clinically available biomarkers can predict pathological complete response(pCR)for esophageal squamous cell carcinomas(ESCCs)with neoadjuvant chemoradiotherapy(nCRT).Considering that antitumor immunity status is an important determinant for nCRT,we performed an integrative analysis of immune-related gene profiles from pretreatment biopsies and constructed the first individualized immune signature for pCR and outcome prediction of ESCCs through a multicenter analysis.During the discovery phase,14 differentially expressed immune-related genes(DEIGs)with greater than a twofold change between pCRs and less than pCRs( | Chaoqi Zhang Guochao Zhang Nan Sun Zhen Zhang Liyan Xue Zhihui Zhang Haijun Yang Yuejun Luo Xiaoli Zheng Yonglei Zhang Yufen Yuan Ruixue Lei Zhaoyang Yang Bo Zheng Le Wang Yun Che Feng Wang Sihui Wang Shugeng Gao Qi Xue Yi Zhang Jie He | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 7 |
| 3 | esveratrol inhibits necroptosis by mediating the TNF-α/RIP1/RIP3/MLKL pathway in myocardial hypoxia/reoxygenation injury显示文摘Resveratrol(RES)protects myocardial cells from hypoxia/reoxygenation(H/R)-caused injury.However,the mechanism of this effect has not been clarified.Thus,in this study,we aimed to determine whether RES attenuates H/R-induced cell necroptosis by inhibiting the tumor necrosis factor-alpha(TNF-α)/receptor-interacting protein kinase 1(RIP1)/RIP3/mixed-lineage kinase domain-like(MLKL)signaling pathway.Rat myocardial ischemia/reperfusion(I/R)models and H/R-injured cell models were constructed.Our study showed that myocardial H/R injury significantly increased the levels of TNF-α,RIP1,RIP3,and p-MLKL/MLKL by western blot analysis.Cell viability assay and 4,6-dianmidino-2-phenylindole(DAPI)-propidium iodide staining showed that the cell viability was decreased,and necroptosis was increased after myocardial H/R injury.The expressions of TNF-α,RIP1,RIP3,and p-MLKL/MLKL in H/R myocardial cells treated with different concentrations of RES were significantly downregulated.In addition,we also found that the cell viability was increased and necroptosis was decreased in dose-dependent manners when H/R-injured cells were treated with RES.In addition,the enhanced effect of TNF-αon necroptosis in myocardial H/R-injured cells was improved by RES,and the effect of RES was confirmed in vivo in I/R rats.This study also showed that RES suppresses necroptosis in H9c2 cells,which may occur through the inhibition of the TNF-α/RIP1/RIP3/MLKL signaling pathway.Our data suggest that necroptosis is a promising therapeutic target and may be a promising therapeutic target for the treatment of myocardial I/R injury. | Yongjun Hu Hongwei Pan Jianqiang Peng Jin He Mingxiang Tang Sulan Yan Jingjing Rong Junshan Li Zhaofen Zheng Haijun Wang Yanfu Liu Xin Zhong | 2021 | Acta Biochimica et Biophysica Sinica2021，53，4： | 6 |
| 4 | Containment of soft wall casing wrapped with Kevlar fabric显示文摘Aramid fabrics have been commonly used in the civil turbofan engine fan blade containment system for its excellent performance. To investigate the behavior and capability of soft wall containment casing, a series of fan blade released tests were conducted on the high-speed spin tester.The soft wall casing was fabricated by wrapping multiple layers of Kevlar49 plain woven fabric around a thin steel ring. Casings with different inner metal ring and outer fabric layers number were compared. The method of using the explicit dynamic software LS-DYNA to establish the finite element analysis model for the quantitative analysis of the containment process was developed and conducted. The simulation results are in good agreement with the test results. It is shown that the containment process of the soft wall casing can be divided into three impact stages. The casing with low-stiffness inner metal ring will get severe overall deformation and lose the structural integrity when it suffers the blade impact. Kevlar fabric layers will appear large bulge on outside surface and absorb the most impact dynamic energy of the high speed released fan blade. By summing up the results of the test and simulation, an empirical critical equation was derived to describe the relationship between the released blade dynamic energy and the Kevlar fabric thickness. | Zekan HE Haijun XUAN Conger BAI Manli SONG Zhuoshen ZHU | 2019 | Chinese Journal of Aeronautics2019，32，4： | 5 |
| 5 | Containment ability and groove depth design of U type protection ring显示文摘High-energy rotor uncontained failure can cause catastrophic damage effects to aircraft systems if not addressed in design. In this paper, numerical simulations of three high-energy rotor disk fragments impacting on U type protection rings are carried out using LS-DYNA. Protection rings with the same mass and different groove depths are designed to study the influence of the groove depth. Simulation results including kinetic energy and impact force variation of single fragment are presented. It shows that the groove depth infects both the axial containment ability of the protection ring and the transfer process of energy. The depth of groove ought to be controlled to an appropriate value to meet both the requirement of axial containment and higher safety factor. Verification test on high-speed spin tester has been conducted and shows that protection ring with appropriate U structure can resist the impact of the disk burst fragments. The ring is inflated from a circular to an oval-triangle shape. The corresponding simulation shows good agreement with the test. | Bai Conger Xuan Haijun Huang Xiannian He Zekan Hong weirong | 2016 | Chinese Journal of Aeronautics2016，29，2： | 5 |
| 6 | ZmSRL5 is involved in drought tolerance by maintaining cuticular wax structure in maize显示文摘Cuticular wax is a natural barrier on terrestrial plant organs,which protects plants from damages caused by a variety of stresses.Here,we report the identification and functional characterization of a cuticular-wax-related gene,Zea mays L.SEMI-ROLLED LEAF 5(ZmSRL5).The loss-of-function mutant srl5,which was created by a 3,745 bp in-sertion in the first intron that led to the premature tran-script,exhibited abnormal wax crystal morphology and distribution,which,in turn,caused the pleiotropic pheno-types including increased chlorophyll leaching and water loss rate,decreased leaf temperature,sensitivity to drought,as well as semi-rolled mature leaves.However,total wax amounts showed no significant difference between wild type and semi-rolled leaf5(srl5)mutant.The phenotype of srl5 was confirmed through the generation of two allelic mutants using CRISPR/Cas9.ZmSRL5 encodes a CASPARIAN-STRIP-MEMBRANE-DOMAIN-LIKE(CASPL)protein located in plasma membrane,and highly expressed in developing leaves.Further analysis showed that the expressions of the most wax related genes were not affected or slightly al-tered in srl5.This study,thus,primarily uncovers that ZmSRL5 is required for the structure formation of the cu-ticular wax and could increase the drought tolerance by maintaining the proper cuticular wax structure in maize. | Zhenyuan Pan Min Liu Hailiang Zhao Zengdong Tan Kun Liang Qin Sun Dianming Gong Haijun He Wenqi Zhou Fazhan Qiu | 2020 | Journal of Integrative Plant Biology2020，62，12： | 5 |
| 7 | Exosomes derived from 3D-cultured MSCs improve therapeutic effects in periodontitis and experimental colitis and restore the Th17 cell/Treg balance in inflamed periodontium显示文摘Although mesenchymal stem cell-derived exosomes(MSC-exos)have been shown to have therapeutic effects in experimental periodontitis,their drawbacks,such as low yield and limited efficacy,have hampered their clinical application.These drawbacks can be largely reduced by replacing the traditional 2D culture system with a 3D system.However,the potential function of MSC-exos produced by 3D culture(3D-exos)in periodontitis remains elusive.This study showed that compared with MSC-exos generated via 2D culture(2D-exos),3D-exos showed enhanced anti-inflammatory effects in a ligature-induced model of periodontitis by restoring the reactive T helper 17(Th17)cell/Treg balance in inflamed periodontal tissues.Mechanistically,3D-exos exhibited greater enrichment of miR-1246,which can suppress the expression of Nfat5,a key factor that mediates Th17 cell polarization in a sequence-dependent manner.Furthermore,we found that recovery of the Th17 cell/Treg balance in the inflamed periodontium by the local injection of 3D-exos attenuated experimental colitis.Our study not only showed that by restoring the Th17 cell/Treg balance through the miR-1246/Nfat5 axis,the 3D culture system improved the function of MSC-exos in the treatment of periodontitis,but also it provided a basis for treating inflammatory bowel disease(IBD)by restoring immune responses in the inflamed periodontium. | Yong Zhang Jiayao Chen Haijun Fu Shuhong Kuang Feng He Min Zhang Zongshan Shen Wei Qin Zhengmei Lin Shuheng Huang | 2021 | International Journal of Oral Science2021，13，4： | 4 |
| 8 | Monitoring of atmospheric radionuclides from the Fukushima nuclear accident and assessing their impact on Xi'an, China显示文摘Aerosol radionuclides (131I, 134Cs, 137Cs) and gaseous radioactive xenon (133Xe) were monitored at Xi'an, China following the accident at the Fukushima nuclear power plant in March 2011. The additional annual effective dose attributable to the Fukushima emissions was much lower than the public annual effective dose from natural radiation, according to Chinese national standards. The monitoring results were compared with data from other countries as well as with the radionuclide concentrations observed in Xi'an after the Chernobyl nuclear accident in 1986. Possible transport pathways of the released radionuclides from Fukushima to Xi'an were investigated. The occurrence of an anticyclone in the Pacific Ocean region and the extended period over which the radionuclides were released made the determination transport pathways complex, but divergence in the plume and easterly flow evidently brought the initial suite of radionuclides to Xi'an. | LIU LongBo WU Shan CAO JunJi XIE Feng SHI QuanLin ZHANG ChangYun TANG HanBing HE XiaoBin ZHANG Rong CHEN LiYun WEI GuanYi ZHANG ZhiHong ZHANG JiaMei DANG HaiJun | 2013 | Chinese Science Bulletin2013，58，13： | 4 |
| 9 | Characteristics and mechanisms of turboshaft engine axial compressor casing containment显示文摘To investigate the containment characteristics and mechanisms of axial compressor blade and casing in turboshaft engine,experimental and simulation research is conducted on Titanium alloy axial compressor blades and stainless steel simulator casings in this paper.Experiments for four thicknesses(from 0.8 mm to 1.4 mm)of casings are presented on high-speed spin tester.Perforation,ricochet with and without failure of the casings are obtained in test results.Three obvious bulges or dishing region are observed,petaling failure occurs in the first bulge or the third deformation region.Parabolic and elongated dimples are observed at the fracture surface.Finite Element(FE)models with calibrated Johnson-Cook material behavior law are built and analyzed by using explicit dynamic software for a better understanding on the containment behavior.Good agreement is obtained between the experimental observations and numerical predictions.The evolution of the impact force,energy absorption,temperature increase and the cracks’propagation are analyzed.Three force peaks occur in the impact process.Energy analysis reveals that penetration condition of ricochet with failure leads to most internal energy of the casing. | Zekan HE Xiaojun GUO Haijun XUAN Xiaoming SHAN Xiaojing FAN Chuanyong CHEN Weirong HONG | 2021 | Chinese Journal of Aeronautics2021，34，1： | 4 |
| 10 | On the low reproducibility of cancer studies显示文摘INTRODUCTION Previous reports have suggested that close to 90% of cancer biology publications are irreproducible.The low number has recently been corroborated by five detailed replication studies in eLife,which have been commented on in Nature (Replication studies offer much more than technical details. Nature 2017;541:259-60).While the irreproducibility is often attributed to human factors,which are remediable,the reason might be biological and the irreproducibility is intrinsic to such studies. The low reproducibility,reflecting the diversity in the evolutionary pathways of tumourigenesis,will likely significantly impact clinical strategies. | Haijun Wen Hurng-Yi Wang Xionglei He Chung-I Wu | 2018 | National Science Review2018，5，5： | 3 |
| 11 | Infrared drying kinetics and moisture diffusivity modeling of pork显示文摘This study investigated the drying kinetics of pork slice in infrared drying condition.Drying temperature,slice thickness and initial moisture content were selected as influencing factors on the drying characteristics and drying rate of pork slice.Drying curves obtained from the experimental data were fitted to semi theoretical and/or empirical thin layer drying models.The effects of drying temperature and slice thickness on the model constants were evaluated by the multiple regression method.All the models were compared according to three statistical indexes,i.e.,root mean square error,chi-square and modeling efficiency.The slice thickness,drying temperature and initial moisture content have significant influences on the effective diffusivity coefficient of pork.The results showed that the drying rate of pork slices increased with the increases of drying temperature and initial moisture content.The decreases of slice thickness also led to an increase of drying rate.The Henderson and Pabis model can best describe the drying curves of pork. | Ling Jing Teng Zhaosheng Lin Haijun Wen He | 2017 | International Journal of Agricultural and Biological Engineering2017，10，3： | 3 |
| 12 | On the founder effect in COVID-19 outbreaks:how many infected travelers may have started them all?显示文摘How many incoming travelers(I0 at time 0,equivalent to the‘founders’in evolutionary genetics)infected with SARS-CoV-2 who visit or return to a region could have started the epidemic of that region?I0 would be informative about the initiation and progression of epidemics.To obtain I0,we analyze the genetic divergence among viral populations of different regions.By applying the‘individual-output’model of genetic drift to the SARS-CoV-2 diversities,we obtain I0<10,which could have been achieved by one infected traveler in a long-distance flight.The conclusion is robust regardless of the source population,the continuation of inputs(It for t>0)or the fitness of the variants.With such a tiny trickle of human movement igniting many outbreaks,the crucial stage of repressing an epidemic in any region should,therefore,be the very first sign of local contagion when positive cases first become identifiable.The implications of the highly‘portable’epidemics,including their early evolution prior to any outbreak,are explored in the companion study(Ruan et al.,personal communication). | Yongsen Ruan Zhida Luo Xiaolu Tang Guanghao Li Haijun Wen Xionglei He Xuemei Lu Jian Lu Chung-I Wu | 2021 | National Science Review2021，8，1： | 3 |
| 13 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |
| 14 | First results on ^(76)Ge neutrinoless double beta decay from CDEX-1 experiment显示文摘We report the first results on ^(76)Ge neutrinoless double beta decay from stage one of the China dark-matter experiment(CDEX).A p-type point-contact high-purity germanium detector with a mass of 994 g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304 kg d has been analyzed over a wide spectral band from 500 keV to 3 MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039 MeV energy range. The half-life of ^(76)Ge neutrinoless double beta decay derived based on this result is T^(0ν)1/2>6.4×10^(22) yr(90% C.L.). An upper limit on the effective Majorana-neutrino mass of 5.0 eV has been achieved. | Li Wang Qian Yue KeJun Kang JianPing Cheng YuanJing Li TszKing Henry Wong ShinTed Lin JianPing Chang JingHan Chen QingHao Chen YunHua Chen Zhi Deng Qiang Du Hui Gong Li He QingJu He JinWei Hu HanXiong Huang TengRui Huang LiPing Jia Hao Jiang HauBin Li Hong Li JianMin Li Jin Li Jun Li Xia Li XueQian Li YuLan Li FongKay Lin ShuKui Liu Hao Ma JingLu Ma XingYu Pan Jie Ren XiChao Ruan ManBin Shen Vivek Sharma Lakhwinder Singh Manoj Kumar Singh Manoj Kumar Singh Arun Kumar Soma ChangJian Tang WeiYou Tang ChaoHsiung Tseng JiMin Wang Qing Wang ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue LiTao Yang SongWei Yang Nan Yi ChunXu Yu HaiJun Yu WeiHe Zeng XiongHui Zeng Zhi Zeng Lan Zhang YunHua Zhang MingGang Zhao Wei Zhao JiFang Zhou ZuYing Zhou JingJun Zhu WeiBin Zhu ZhongHua Zhu | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，7： | 3 |
| 15 | Noncontrast-enhanced MRI-based Noninvasive Score for Portal Hypertension(CHESS1802):An International Multicenter Study显示文摘Background and Aims:This study aimed to determine the performance of the non-invasive score using noncontrastenhanced MRI(CHESS-DIS score)for detecting portal hy-pertension in cirrhosis.Methods:In this international multicenter,diagnostic study(ClinicalTrials.gov,NCT03766880),patients with cirrhosis who had hepatic venous pressure gradient(HVPG)measurement and noncontrast-enhanced MRI were prospectively recruited from four university hospitals in China(n=4)and Turkey(n=1)between December 2018 and April 2019.A cohort of patients was retrospectively recruited from a university hospital in Italy between March 2015 and November 2017.After segmentation of the liver on fat-suppressed T1-weighted MRI maps,CHESS-DIS score was calculated automatically by an in-house developed code based on the quantification of liver surface nodularity.Results:A total of 149 patients were included,of which 124 were from four Chinese hospitals(training cohort)and 25 were from two international hospitals(validation cohort).A positive correlation between CHESS-DIS score and HVPG was found with the correlation coefficients of 0.36(p<0.0001)and 0.55(p<0.01)for the training and validation cohorts,respectively.The area under the receiver operating characteristic curve of CHESS-DIS score in detection of clinically significant portal hypertension(CSPH)was 0.81 and 0.9 in the training and validation cohorts,respectively.The intra-class correlation coefficients for assessing the inter-and intra-observer agreement were 0.846 and 0.841,respectively.Conclusions:A non-invasive score using noncontrast-enhanced MRI was developed and proved to be significantly correlated with invasive HVPG.Besides,this score could be used to detect CSPH in patients with cirrhosis. | Yanna Liu Tianyu Tang NecatiÖrmeci Yifei Huang Jitao Wang Xiaoguo Li Zhiwei Li Weimin An Dengxiang Liu Chunqing Zhang Changchun Liu Jinqiang Liu Chuan Liu Guangchuan Wang Cristina Mosconi Alberta Cappelli Antonio Bruno Seray Akçalar EmrecanÇelebioğlu EvrenÜstüner Sadık Bilgiç Zeynep Ellik ÖzgünÖmer Asiller Lei Li Haijun Zhang Ning Kang Dan Xu Ruiling He Yan Wang Yang Bu Ye Gu Shenghong Ju Rita Golfieri Xiaolong Qi | 2021 | Journal of Clinical and Translational Hepatology2021，9，6： | 3 |
| 16 | Progress in octahedral spherical hohlraum study显示文摘In this paper,we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study.From our theoretical study,the octahedral spherical hohlraums with 6 Laser Entrance Holes(LEHs)of octahedral symmetry have robust high symmetry during the capsule implosion at hohlraum-to-capsule radius ratio larger than 3.7.In addition,the octahedral spherical hohlraums also have potential superiority on low backscattering without supplementary technology.We studied the laser arrangement and constraints of the octahedral spherical hohlraums,and gave a design on the laser arrangement for ignition octahedral hohlraums.As a result,the injection angle of laser beams of 50°-60°was proposed as the optimum candidate range for the octahedral spherical hohlraums.We proposed a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields,in order to increase the laser coupling efficiency and improve the capsule symmetry and to mitigate the influence of the wall blowoff on laser transport.We studied on the sensitivity of the octahedral spherical hohlraums to random errors and compared the sensitivity among the octahedral spherical hohlraums,the rugby hohlraums and the cylindrical hohlraums,and the results show that the octahedral spherical hohlraums are robust to these random errors while the cylindrical hohlraums are the most sensitive.Up till to now,we have carried out three experiments on the spherical hohlraum with 2 LEHs on Shenguang(SG)laser facilities,including demonstration of improving laser transport by using the cylindrical LEHs in the spherical hohlraums,spherical hohlraum energetics on the SGIII prototype laser facility,and comparisons of laser plasma instabilities between the spherical hohlraums and the cylindrical hohlraums on the SGIII laser facility. | Ke Lan Jie Liu Zhichao Li Xufei Xie Wenyi Huo Yaohua Chen Guoli Ren Chunyang Zheng Dong Yang Sanwei Li Zhiwen Yang Liang Guo Shu Li Mingyu Zhang Xiaoying Han Chuanlei Zhai Lifei Hou Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Feng Wang Guanghui Yuan Haijun Zhang Bobin Jiang Lizhen Huang Wei Zhang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Xuewei Deng Dongxia Hu Wei Zhou Huaiting Jia Yongkun Ding Wanguo Zheng Xiantu He | 2016 | Matter and Radiation at Extremes2016，1，1： | 2 |
| 17 | Enhanced photocatalytic properties of ultra-long nanofiber synthesized from pure titanium powders显示文摘Using Ti powder as reagent,ultra-long TiO2 nanofibers were prepared via hydrothermal method in NaOH solution.The samples were char-acterized respectively by means of field emission scanning electron microscopy (FESEM),transmission electron microscopy (TEM) with selected area electron diffraction (SAED),and X-ray diffraction (XRD).The diameter and the length of the ultra-long TiO2 nanofiber were ~100 nm and >200μm,respectively.The ultra-long TiO2 nanofibers were anatase after heat treatment at 450 ?C for 1 h.Moreover,the optical properties of the products were investigated by UV-visible light absorption spectrum.Furthermore,methyl orange was used as a target molecule to estimate the photocatalytic activity of the specimens.Under the same testing conditions,the photocatalytic activity of the ultra-long TiO2 nanofibers was higher than that of P25.Direct electrical pathway and improved light-harvesting efficiency were crucial for the superior photocatalytic activity of the ultra-long TiO2 nanofibers. | Tao, Jie Dong, Xiang Zhu, Hong Tao, Haijun He, Pingting | 2012 | Rare Metals2012，31，1： | 2 |

| 19 | Three-Dimensional Conformal Radiotherapy for Rectal Cancer and the Changes in Cancer Multi-biomarkers显示文摘OBJECTIVE To investigate the clinical efficacy of three-dimensional conformal radiotherapy(3D-CRT)for local y advanced or postoperatively relapsed rectal cancer,and to examine the changes in cancer multi-biomarkers. METHODS Sixty patients with locally advanced or postoperatively relapsed rectal cancer were randomly divided into two groups after 40 Gy external radiation,namely a late-course 3D-CRT group and a conventional radiotherapy group that served as the control.There were 30 patients in each group.For patients in the 3D-CRT group,multi-biomarkers were measured before and after radiotherapy and after relapse. RESULTS Response rates in the 3D-CRT and the control groups were 86.7%(26/30)and 70%(21/30)respectively,without a significant difference (P>0.05).The 1-,2-and 3-year survival rates were 80%,53.3%and 36.7% in the 3D-CRT group;in the control group the rates were 56.7%,40%and 13.3%respectively,with a significant difference(P=0.0213).CEA,CA19-9, CA242 and FER decreased after radiotherapy in the 3D-CRT group,P<0.01, indicating a significant difference.The values after relapse were higher than those without relapse,P<0.01,indicating a significant difference. CONCLUSION Conventional radiotherapy with a 3D-CRT boost gives better therapeutic effect to patients with locally advanced or postoperatively local y relapsed rectal cancer.A multi-biomarker protein chip diagnosis system can be utilized as an effective tool to determine the therapeutic effect and prognosis. | Rui Wei Yangde Zhang Jiantai He Liangfang Shen Jidong Hong Haijun Wu | 2007 | Chinese Journal of Clinical Oncology2007，4，6： | 2 |
