| 1 | 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 |

| 3 | Influence of Atmospheric Refraction on Horizontal Angle Surveying显示文摘Side-refraction is the main error source of horizontal angle surveying, but it has little influence on the sides by analyzing the influence of atmospheric-infraction on the ultrahigh-precision side and angle surveying. Choosing oriented direction is crucial to distance and angle measurement in triangulateration network. How to select the oriented direction during angle measurement is presented, and the means to check the quality of auto-surveying with Georobot is brought forward as well. At last some solutions to reduce the influence of side-refraction while disposing and surveying ultrahigh-precision triangulateration network are put forward. | ZHANG Zhenglu DENG Yong LUO Changlin MEI Wensheng | 2006 | Geo-Spatial Information Science2006，9，3： | 3 |
| 4 | Chemical synthesis of Ub-AMC via ligation of peptide hydrazides显示文摘The C-terminal conjugate of ubiquitin with 7-amino-4-methylcoumarin (Ub-AMC) is an important probe for fluorescencebased analysis of deubiquitinating enzyme (DUB) activity. It is important to develop more efficient methods for the preparation of Ub-AMC because the currently available technology is still expensive for scaled-up production. In the present work we report an efficient strategy for total chemical synthesis of Ub-AMC through ligation of peptide hydrazides. Three peptide segments are assembled via N-to-C sequential ligation and the resulting product is converted to Ub-AMC via TCEP-mediated desulfurization. The synthetic Ub-AMC is shown to have expected biological functions | LIANG Jun FANG GeMin HUANG XiuLiang MEI ZiQing LI Juan TIAN ChangLin LIU Lei | 2013 | Science China Chemistry2013，56，9： | 2 |

| 12 | Darbepoetin alfa injection versus epoetin alfa injection for treating anemia of Chinese hemodialysis patients with chronic kidney failure:A randomized,open-label,parallel-group,non-inferiority Phase III trail显示文摘Background:Erythropoietin is a glycoprotein that mainly regulates erythropoiesis.In patients with chronic renal failure with anemia,darbepoetin alfa can stimulate erythropoiesis,correct anemia,and maintain hemoglobin levels.This study was designed to demonstrate the efficacy and safety of darbepoetin alfa injections as being not inferior to epoetin alfa injections(Recombinant Human Erythropoietin injection,rHuEPO)when maintaining hemoglobin(Hb)levels within the target range(10.0-12.0 g/dL)for the treatment of renal anemia.Methods:Ninety-five patients were enrolled in this study from April 15,2013 to April 10,2014 at 25 sites.In this study,patients(n=95)aged 18-70 years were randomized into a once per week intravenous darbepoetin alfa group(n=56)and a twice or three times per week intravenous epoetin alfa group(n=39)for 28 weeks,who had anemia with hemoglobin levels between 6 g/dL and 10 g/dL due to chronic kidney disease(CKD)and were undergoing hemodialysis or hemofiltration with ESA-naive(erythropoiesis stimulating agent-naive).The primary efficacy profile was the mean Hb level(the non-inferiority margin was-1.0 g/dL,week 21-28);the secondary efficacy profiles were the Hb increase rate(week 0-4),the target Hb achievement cumulative rate and time,the change trends of the Hb levels,and the target Hb maintenance ratio.Adverse events(AEs)were observed and compared,and the efficacy and safety were analyzed between the two treatment groups.Additionally,the frequencies of dose adjustments between the darbepoetin alfa and epoetin alfa groups were compared during the treatment period.SAS?software version 9.2 was used to perform all statistical analyses.Descriptive statistics were used for all efficacy,safety,and demographic variable analyses,including for the primary efficacy indicators.Results:The mean Hb level was 11.3 g/dL in the darbepoetin alfa group and 10.7 g/dL in the epoetin alfa group,respectively;the difference of the lower limits of the 95%confidence intervals(CI)between the two groups was 0.1 g/dL(>-1.0 g/dL),and non-inferiority was proven;the Hb levels started to increase in the first four weeks at a similar increase rate;no obvious differences were observed between the groups in the target Hb achievement cumulative rates,and the Hb levels as well as the target Hb level maintenance rate changed over time.The incidence of AEs was 62.5%in the darbepoetin alfa group and 76.9%in the epoetin alfa group.All the adverse events observed in the study were those commonly associated with hemodialysis.Conclusion:Darbepoetin alfa intravenously once per week can effectively increase Hb levels and maintain the target Hb levels well,which makes it not inferior to epoetin alfa intravenously twice or three times per week.Darbepoetin alfa shows an efficacy and safety comparable to epoetin alfa for the treatment of renal anemia. | Nan Chen Changying Xing Jianying Niu Bicheng Liu Junzhou Fu Jiuyang Zhao Zhaohui Ni Mei Wang Wenhu Liu Jinghong Zhao Ling Zhong Xiongfei Wu Wenge Li Yuqing Chen Wei Shi Jianghua Chen Aiping Yin Ping Fu Rong Wang Gengru Jiang Fanfan Hou Guohua Ding Jing Chen Gang Xu Yuichiro Kondo Yuliang Su Changlin Mei | 2022 | Chronic Diseases and Translational Medicine2022，8，1： | 1 |
