| 2 | The abnormal expression of retinoic acid receptor-β,p53 and Ki67 protein,n normal,premalignant and malignant esophageal tissues显示文摘AIM: Esophageal cancer remains a significant healthiproblem worldwide. It is important to investigate alterationsin expression of retinoic acid receptor-β, p53 and Ki67proteins in esophageal carcinogenesis.METHODS: To find biomarkers for early identification ofesophageal cancer, we analyzed the retinoic acid receptor-j3,p53 protein and the proliferation marker Ki67 in surgicalspecimens of normal, mildly, and severely dysplastic andmalignant esophageal tissues by in situ hybridization ofRNA and immunohistochemistry.RESULTS: RAR-β was expressed in 94.3 %(33/35) of normalmucosae, 67.8 %(19/28) of the mild, 58.1% (18/31) of thesevere ieaions and 53.2 % (116/218) of tumor samples. RAR-β mRNA was expressed in 62.7 % (42/67), 55.1% (43/78) and29.2 % (7/24) of well, moderated and poorly differentiatedSSCs. The p53 and Ki67 proteins were 5.9 % (2/34) of thenormal mucosa. P53 and Ki67 stained positively in 10.7 % (3/28) and 21.4 % (6/28) of mild dysplasia, and 51.6 %(16/31)and 58. 1% (18/31) of severely dysplasia respectively.Samples from esophageal cancer showed no higher levers ofp53 and Ki67 expression than seen in severely dysplasticlesions. There was significant difference of RAR-β、 p53 andKi67 expression between normal mucosa and dysplatictissue or esophageal cancer.CONCLUSION: Loss of RAR-β expression and acctnulation ofp53 and Ki67 proteins may serve as biomarkers for earlyidentification of esophageal cancer in the high-riskpopulations. | Min Xu Sheng-Zu Chen,Department of Nuclear Medcine,Cancer Hospital(Institute),Peking Union Medical College and Chinese Academy of Medical Sciences,Beijing 10002,1,China Yu-Lan Jin Jun Fu Hong Huang Ping Qu Hai-Mei Tian ZhaoYang Liu Wei Zhang,Central Laboratory for Tumor Biology,Cancer Hospital(Institute),Peking Union Medical College and Chinese Academy of Medical Sciences,Beijing 100021,China | 2002 | World Journal of Gastroenterology2002，8，2： | 34 |

| 6 | Os isotopic compositions of a cobalt-rich ferromanganese crust profile in Central Pacific显示文摘187Os/188Os ratios in all sub-layers of the Co-rich ferromanganese crust MP5D17 from Line Seamount in Central Pacific have been systematically determined. The 187Os/188Os values in this crust are highly variable, ranging from 0.4262 to 1.0155. From the bottom to the top, the os-mium isotopic ratios of the crust display a regular variation trend, which correlates well with its changes in structure and texture in the vertical profile. In comparison with the evolu-tion curve of Os isotopic composition in seawater over the past 80 Ma, a similar evolution tendency can be found with respect to the Os isotopic composition of the crust in this study. It is preliminarily concluded that the crust MP5D17 began to grow at about 72 Ma, and underwent three growth hiatuses, corresponding to the geological ages of 64, 53 and 37 Ma, respectively. | FU Yazhou PENG Jiantang QU Wenjun HU Ruizhong SHI Xuefa DU Andao | 2005 | Chinese Science Bulletin2005，50，18： | 13 |
| 7 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |

| 9 | CO2 hydrogenation to methanol over Cu/CeO2 and Cu/ZrO2 catalysts:Tuning methanol selectivity via metal-support interaction显示文摘Copper-based catalysts for CO2 hydrogenation to methanol are supported on ZrO2 and CeO2,respectively.Reaction results at 3.0 MPa and temperatures between 200 and 300°C reveal that Cu catalysts supported on ZrO2 and CeO2 exhibit better activity and selectivity than pure Cu catalyst due to Cu-support(ZrO2 and CeO2)interaction.Combining the structural characterizations with in-situ diffuse reflectance infrared Fourier transform spectroscopy(in-situ DRIFTS),Cu/CeO2 shows the higher methanol selectivity due to the formation of main carbonates intermediates,which are closely related with the oxygen vacancies over Cu/CeO2.In contrast,bicarbonate and carboxyl species are observed on Cu/ZrO2,which originates from the hydroxyl groups presented on catalyst surfaces.Difference in CO2 adsorption intermediates results in the distinct methanol selectivity over the two catalysts. | Weiwei Wang Zhenping Qu Lixin Song Qiang Fu | 2020 | Journal of Energy Chemistry2020，29，1： | 11 |
| 10 | Effect of cooling rates on dendrite spacings of directionally solidified DZ125 alloy under high thermal gradient显示文摘The dendrite morphologies and spacings of directionally solidified DZ125 superalloy were investigated under high thermal gradient about 500 K/cm. The results reveal that, with increasing cooling rate, both the spacings of primary and secondary dendrite arms decrease, and the dendrite morphologies transit from coarse to superfine dendrite. The secondary dendrite arms trend to be refined and be well developed, and the tertiary dendrite will occur. The predictions of the Kurz/Fisher model and the Hunt/Lu model accord basically with the experimental data for primary dendrite arm spacing. The regression equation of the primary dendrite arm spacings λ1 and the cooling rate Vc is λ1=0.013Vc-0.32. The regression equation of the secondary dendrite arm spacing λ2 and the cooling rate Vc is λ2=0.00258Vc-0.31, which gives good agreement with the Feurer/Wunderlin model. | ZHANG Weiguo LIU Lin ZHAO Xinbao HUANG Taiwen YU Zhuhuan QU Min FU Hengzhi | 2009 | Rare Metals2009，28，6： | 11 |

| 14 | A 2-kb Mycovirus Converts a Pathogenic Fungus into a Beneficial Endophyte for Brassica Protection and Yield Enhancement显示文摘Mycoviruses are viruses that infect fungi,and hypovirulence-associated mycoviruses have the potential to control fungal diseases.However,it is unclear how mycovirus-mediated hypovirulent strains live and survive in the field,and no mycovirus has been applied for field crop protection.In this study,we found that a previously identified small DNA mycovirus(SsHADV-1)can convert its host,Sclerotinia sclerotiorum,from a typical necrotrophic pathogen to a beneficial endophytic fungus.SsHADV-1 downregulates the expression of key pathogenicity factor genes in S.sclerotiorum during infection.When growing in rapeseed,the SsHADV-1-infected strain DT-8 significantly regulates the expression of rapeseed genes involved in defense,hormone signaling,and circadian rhythm pathways.As a result,plant growth is promoted and disease resistance is enhanced.Field experiments showed that spraying DT-8 at the early flowering stage can reduce the disease severity of rapeseed stem rot by 67.6%and improve yield by 14.9%.Moreover,we discovered that SsHADV-1 could also infect other S.sclerotiorum strains on DT-8-inoculated plants and that DT-8 could be recovered from dead plants.These findings suggest that the mycoviruses may have the ability to shape the origin of endophytism.Our discoveries suggest that mycoviruses may influence the origin of endophytism and may also offer a novel strategy for disease control in which mycovirus-infected strains are used to improve crop health and release mycoviruses into the field. | Hongxiang Zhang Jiatao Xie Yanping Fu Jiasen Cheng Zheng Qu Zhenzhen Zhao Shufen Cheng Tao Chen Bo Li Qianqian Wang Xinqiang Liu Binnian Tian David B.Collinge Daohong Jiang | 2020 | Molecular Plant2020，13，10： | 9 |
| 15 | Simulation and experimental investigation of inner-jet electrochemical grinding of GH4169 alloy显示文摘GH4169 alloy is one of the most commonly used materials in aero engine turbine blades,but its machinability is poor because of its excellent strength at high temperatures. Electrochemical machining(ECM) has become a common method for machining this alloy and other difficult-tomachine materials. Electrochemical grinding(ECG) is a hybrid process combining ECM and conventional grinding. In this paper, investigations conducted on inner-jet ECG of GH4169 alloy are described. Two types of inner-jet ECG grinding wheels were used to machine a flat bottom surface.The machining process was simulated using COMSOL software, and machining gaps under different machining parameters were obtained. In addition, maximum feed rates and maximum material removal rates under different machining parameters were studied experimentally. The maximum sizes and the uniformity of the distributions of the gaps machined by the two grinding wheels were compared. The effects of different applied voltages on the machining results were also investigated. | Hansong LI Shuxing FU Qingliang ZHANG Shen NIU Ningsong QU | 2018 | Chinese Journal of Aeronautics2018，31，3： | 9 |

| 17 | Six-long non-coding RNA signature predicts recurrence-free survival in hepatocellular carcinoma显示文摘BACKGROUND Recent evidence shows that long non-coding RNAs(lncRNAs) are closely related to hepatogenesis and a few aggressive features of hepatocellular carcinoma(HCC). Increasing studies demonstrate that lncRNAs are potential prognostic factors for HCC. Moreover, several studies reported the combination of lncRNAs for predicting the overall survival(OS) of HCC, but the results varied. Thus,more effort including more accurate statistical approaches is needed for exploring the prognostic value of lncRNAs in HCC.AIM To develop a robust lncRNA signature associated with HCC recurrence to improve prognosis prediction of HCC.METHODS Univariate COX regression analysis was performed to screen the lncRNAs significantly associated with recurrence-free survival(RFS) of HCC in GSE76427 for the least absolute shrinkage and selection operator(LASSO) modelling. The established lncRNA signature was validated and developed in The Cancer Genome Atlas(TCGA) series using Kaplan-Meier curves. The expression values of the identified lncRNAs were compared between the tumor and non-tumor tissues. Pathway enrichment of these lncRNAs was conducted based on the significantly co-expressed genes. A prognostic nomogram combining the lncRNA signature and clinical characteristics was constructed.RESULTS The lncRNA signature consisted of six lncRNAs: MSC-AS1, POLR2 J4, EIF3 J-AS1,SERHL, RMST, and PVT1. This risk model was significantly associated with the RFS of HCC in the TCGA cohort with a hazard ratio(HR) being 1.807(95%CI[confidence interval]: 1.329-2.457) and log-rank P-value being less than 0.001. The best candidates of the six-lncRNA signature were younger male patients with HBV infection in relatively early tumor-stage and better physical condition but with higher preoperative alpha-fetoprotein. All the lncRNAs were significantly upregulated in tumor samples compared to non-tumor samples(P < 0.05). The most significantly enriched pathways of the lncRNAs were TGF-β signaling pathway, cellular apoptosis-associated pathways, etc. The nomogram showed great utility of the lncRNA signature in HCC recurrence risk stratification.CONCLUSION We have constructed a six-lncRNA signature for prognosis prediction of HCC.This risk model provides new clinical evidence for the accurate diagnosis and targeted treatment of HCC. | Jing-Xian Gu Xing Zhang Run-Chen Miao Xiao-Hong Xiang Yu-Nong Fu Jing-Yao Zhang Chang Liu Kai Qu | 2019 | World Journal of Gastroenterology2019，25，2： | 9 |
| 18 | New Re-Os Isotopic Constrains on the Formation of the Metalliferous Deposits of the Lower Cambrian Niutitang Formation显示文摘The Terreneuvian Epoch(541–521 Ma)is also an important period for metallogenesis in South China, as was represented by the widespread occurrences of Ni-Mo polymetallic layers on the antecedent shallow platform margin and the V-enriched black shales in deeper slope-basin settings. In this study, we have measured Re-Os isochron ages of Ni-Mo polymetallic layers(Songlin, Niuchang, Sancha, Chuanpengwan), V-rich black shales(Bahuang), and non-metalliferous black shales(Shuidong) in the basal Niutitang Formation in Guizhou and Hunan province, South China. The Ni-Mo polymetallic layers and V-enriched black shales have similar Re-Os isochron ages, suggesting concurrent deposition of these two types of metalliferous ores. This suggestion is consistent with the traditional stratigraphic correlation by using the nodular phosphorite bed directly underlying these metalliferous layers as a stratigraphic marker. Furthermore, the metalliferous ores and non-metalliferous black shales have similar initial ^(187)Os/^(188) Os ratios of 0.8–0.9, arguing for a dominant seawater origin with minor contribution of hydrothermal activity. Furthermore, Re-Os isotopic data also imply that Ni-Mo and V ore might have derived from the same source. We suggest that the spatial distribution of metalliferous ores can be explained by the development of non-sulfidic anoxic-suboxic wedge(NSASW) in the slope-basin and sulfidic wedge in the previous platform margin. Upwelling of deep water first transects the mildly reduced, organic rich NSASW, in which V(V) is reduced to V(IV), and is preferentially removed from seawater by organometallic complex formation. As a result, V-rich black shale deposits in the slope-basin of Yangtze Platform. Further movement of deep water into the sulfidic platform margin results in Ni-Mo polymetallic layer formation. | Yong Fu Lin Dong Chao Li Wenjun Qu Haoxiang Pei Wenlang Qiao Bing Shen | 2016 | Journal of Earth Science2016，27，2： | 9 |
| 19 | On the number of rotation symmetric Boolean functions显示文摘Rotation symmetric Boolean functions (RSBFs) have been used as components of different cryptosystems. This class of functions are invariant under circular translation of indices. In this paper, we investigated balanced RSBFs and 1st order correlation immune RSBFs. Based on constructive techniques, we give an accurate enumeration formula for n-variable balanced RSBFs when n is a power of a prime. Furthermore, an original and efficient method to enumerate all n-variable (n prime) 1st order correlationimmune functions is presented. The exact number of 1st order correlation immune RSBFs with 11 variables is 6925047156550478825225250374129764511077684773805520800 and the number of 13 variables has 189 digits. Then for more variables, we also provide a significant lower bound on the number of 1st order correlation immune RSBFs. | FU ShaoJing LI Chao QU LongJiang | 2010 | Science China(Information Sciences)2010，53，3： | 8 |
| 20 | CAS9 is a genome mutator by directly disrupting DNA-PK dependent DNA repair pathway显示文摘With its high efficiency for site-specific genome editing and easy manipulation,the clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR associated protein 9(CAS9)system has become the most widely used gene editing technology in biomedical research.In addition,significant progress has been made for the clinical development of CRISPR/CAS9 based gene therapies of human diseases,several of which are entering clinical trials.Here we report that CAS9 protein can function as a genome mutator independent of any exogenous guide RNA(gRNA)in human cells,promoting genomic DNA double-stranded break(DSB)damage and genomic instability.CAS9 interacts with the KU86 subunit of the DNA-dependent protein kinase(DNA-PK)complex and disrupts the interaction between KU86 and its kinase subunit,leading to defective DNA-PK-dependent repair of DNA DSB damage via non-homologous end-joining(NHEJ)pathway.XCAS9 is a CAS9 variant with potentially higher fidelity and broader compatibility,and dCAS9 is a CAS9 variant without nuclease activity.We show that XCAS9 and dCAS9 also interact with KU86 and disrupt DNA DSB repair.Considering the critical roles of DNA-PK in maintaining genomic stability and the pleiotropic impact of DNA DSB damage responses on cellular proliferation and survival,our findings caution the interpretation of data involving CRISPR/CAS9-based gene editing and raise serious safety concerns of CRISPR/CAS9 system in clinical application. | Shuxiang Xu Jinchul Kim Qingshuang Tang Qu Chen Jingfeng Liu Yang Xu Xuemei Fu | 2020 | Protein & Cell2020，11，5： | 8 |
