| 1 | Identification of a novel coronavirus causing severe pneumonia in human:a descriptive study显示文摘Background:Human infections with zoonotic coronaviruses(CoVs),including severe acute respiratory syndrome(SARS)-CoV and Middle East respiratory syndrome(MERS)-CoV,have raised great public health concern globally.Here,we report a novel batorigin CoV causing severe and fatal pneumonia in humans.Methods:We collected clinical data and bronchoalveolar lavage(BAL)specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital,Hubei province,China.Nucleic acids of the BAL were extracted and subjected to next-generation sequencing.Virus isolation was carried out,and maximum-likelihood phylogenetic trees were constructed.Results:Five patients hospitalized from December 18 to December 29,2019 presented with fever,cough,and dyspnea accompanied by complications of acute respiratory distress syndrome.Chest radiography revealed diffuse opacities and consolidation.One of these patients died.Sequence results revealed the presence of a previously unknownβ-CoV strain in all five patients,with 99.8%to 99.9%nucleotide identities among the isolates.These isolates showed 79.0%nucleotide identity with the sequence of SARS-CoV(GenBank NC_004718)and 51.8%identity with the sequence of MERS-CoV(GenBank NC_019843).The virus is phylogenetically closest to a bat SARS-like CoV(SL-ZC45,GenBank MG772933)with 87.6%to 87.7%nucleotide identity,but is in a separate clade.Moreover,these viruses have a single intact open reading frame gene 8,as a further indicator of bat-origin CoVs.However,the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV,indicating that these viruses might use the same receptor.Conclusion:A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans. | Li-Li Ren Ye-Ming Wang Zhi-Qiang Wu Zi-Chun Xiang Li Guo Teng Xu Yong-Zhong Jiang Yan Xiong Yong-Jun Li Xing-Wang Li Hui Li Guo-Hui Fan Xiao-Ying Gu Yan Xiao Hong Gao Jiu-Yang Xu Fan Yang Xin-Ming Wang Chao Wu Lan Chen Yi-Wei Liu Bo Liu Jian Yang Xiao-Rui Wang Jie Dong Li Li Chao-Lin Huang Jian-Ping Zhao Yi Hu Zhen-Shun Cheng Un-Lin Liu Zhao-Hui Qian Chuan Qin Qi Jin Bin Cao Jian-Wei Wang | 2020 | Chinese Medical Journal2020，，9： | 99 |
| 2 | Evaluation of Tubal Patency with Transvaginal Three-dimensional Hysterosalpingo-contrast Sonography显示文摘Objective To investigate diagnostic efficacy of transvaginal three-dimensional hysterosalpingo-contrast sonography(3D-Hy Co Sy) in assessing tubal patency with chromolaporoscopy. Methods A total of 157 infertile women underwent 3D-Hy Co Sy to evaluate tubal patency. Among these patients, 39 patients were also examined by chromolaporoscopy. The concordance of the two clinical assessment methods was analyzed by the Kappa coefficient test. Results Among the 306 oviducts examined by 3D-Hy Co Sy, 99(32.4%) were patent, 126(41.2%) partially obstructed, and 81(26.5%) completely obstructed. Diagnostic results with 3D-Hy Co Sy were not statistically different from those obtained in the 39 women(78 oviducts) who also underwent chromolaporoscopy, and the two methods showed a high concordance(κ=0.747, P=0.000). The 3D-Hy Co Sy procedure had a sensitivity of 84.8%(28/33), a specificity of 96.2%(25/26), and positive and negative predictive values of 93.3%(28/30) and 86.2%(25/29) respectively. Conclusion Transvaginal 3D-Hy Co Sy can accurately reveal the spatial path and morphology of the oviduct and is a safe and effective method to evaluate tubal patency. | Qi Cheng Sha-sha Wang Xian-sheng Zhu Fan Li | 2015 | Chinese Medical Sciences Journal2015，30，2： | 11 |
| 3 | Secretory/releasing proteome-based identification of plasma biomarkers in HBV-associated hepatocellular carcinoma显示文摘For successful therapy, hepatocellular carcinoma (HCC) must be detected at an early stage. Herein, we used a proteomic approach to analyze the secretory/releasing proteome of HCC tissues to identify plasma biomarkers. Serum-free conditioned media (CM) were collected from primary cultures of cancerous tissues and surrounding noncancerous tissues. Proteomic analysis of the CM proteins permitted the identification of 1365 proteins. The enriched molecular functions and biological processes of the CM proteins, such as hydrolase activity and catabolic processes, were consistent with the liver being the most important metabolic organ. Moreover, 19% of the proteins were characterized as extracellular or membrane-bound. For validation, secretory proteins involved in transforming growth factor-β signaling pathways were validated in plasma samples. Alphafetoprotein (AFP), metalloproteinase (MMP)1, osteopontin (OPN), and pregnancy-specific beta-1-glycoprotein (PSG)9 were significantly increased in HCC patients. The overall performance of MMP1 and OPN in the diagnosis of HCC remained greater than that of AFP. In addition, this study represents the first report of MMP1 as a biomarker with a higher sensitivity and specificity than AFP. Thus, this study provides a valuable resource of the HCC secretome with the potential to investigate serological biomarkers. MMP1 and OPN could be used as novel biomarkers for the early detection of HCC and to improve the sensitivity of biomarkers compared with AFP. | YANG Lei RONG WeiQi XIAO Ting ZHANG Ying XU Bin LIU Yu WANG LiMing WU Fan QI Jun ZHAO XiuYing WANG HongXia HAN NaiJun GUO SuPing WU JianXiong GAO YanNing CHENG ShuJun | 2013 | Science China(Life Sciences)2013，56，7： | 9 |

| 5 | Zika virus infection induces RNAi-mediated antiviral immunity in human neural progenitors and brain organoids显示文摘The re-emergence of Zika virus(ZIKV)in the Western Hemisphere has resulted in global public health crisis since 2015.ZIKV preferentially infects and targets human neural progenitor cells(hNPCs)and causes fetal microcephaly upon maternal infection.hNPCs not only play critical roles during fetal brain development,but also persist in adult brain throughout life.Yet the mechanism of innate antiviral immunity in hNPCs remains largely unknown.Here,we show that ZIKV infection triggers the abundant production of virus-derived small interfering RNAs in hNPCs,but not in the more differentiated progenies or somatic cells.Ablation of key RNAi machinery components significantly enhances ZIKV replication in hNPCs.Furthermore,enoxacin,a broad-spectrum antibiotic that is known as an RNAi enhancer,exerts potent anti-ZIKV activity in hNPCs and other RNAi-competent cells.Strikingly,enoxacin treatment completely prevents ZIKV infection and circumvents ZIKV-induced microcephalic phenotypes in brain organoid models that recapitulate human fetal brain development.Our findings highlight the physiological importance of RNAi-mediated antiviral immunity during the early stage of human brain development,uncovering a novel strategy to combat human congenital viral infections through enhancing RNAi. | Yan-Peng Xu Yang Qiu Boya Zhang Guilai Chen Qi Chen Miao Wang Fan Mo Jiuyue Xu Jin Wu Rong-Rong Zhang Meng-Li Cheng Na-Na Zhang Bao Lyu Wen-Liang Zhu Meng-Hua Wu Qing Ye Da Zhang Jiang-Hong Man Xiao-Feng Li Jie Cui Zhiheng Xu Baoyang Hu Xi Zhou Cheng-Feng Qin | 2019 | Cell Research2019，29，4： | 8 |
| 6 | Dosage effect of multiple genes accounts for multisystem disorder of myotonic dystrophy type 1显示文摘Multisystem manifestations in myotonic dystrophy type 1(DM1)may be due to dosage reduction in multiple genes induced by aberrant expansion of CTG repeats in DMPK,including DMPK,its neighboring genes(SIX5 or DMWD)and downstream MBNLh However,direct evidence is lacking.Here,we develop a new strategy to generate mice carrying multigene heterozygous mutations to mimic dosage reduction in one step by injection of haploid embryonic stem cells with mutant Dmpk,Six5 and Mbnll into oocytes.The triple heterozygous mutant mice exhibit adult-onset DM1 phenotypes.With the additional mutation in Dmwd,the quadruple heterozygous mutant mice recapitulate many major manifestations in congenital DM1.Moreover,muscle stem cells in both models display reduced sternness,providing a unique model for screening small molecules for treatment of DM1.Our results suggest that the complex symptoms of DM1 result from the reduced dosage of multiple genes. | Qi Yin Hongye Wang Na Li Yifu Ding Zhenfei Xie Lifang Jin Yan Li Qiong Wang Xinyi Liu Liuqing Xu Qing Li Yongjian Ma Yanbo Cheng Kai Wang Cuiqing Zhong Qian Yu Wei Tang Wanjin Chen Wenjun Yang Fan Zhang Chen Ding Lan Bao Bin Zhou Ping Hu Jinsong Li | 2020 | Cell Research2020，30，2： | 7 |
| 7 | Computer-aided ionic liquid design for alkane/cycloalkane extractive distillation process显示文摘A computer-aided ionic liquid design(CAILD) study is presented for the frequently encountered alkane/cycloalkane separations in petrochemical industry. Exhaustive experimental data are first collected to extend the UNIFAC-IL model for this system, where the proximity effect in alkanes and cycloalkanes is considered specifically by defining distinct groups. The thermodynamic performances of a large number of ILs for 4 different alkane/cycloalkane systems are then compared to select a representative example of such separations. By applying n-heptane/methylcyclohexane extractive distillation as a case study, the CAILD task is cast as a mixed-integer nonlinear programming(MINLP) problem based on the obtained task-specific UNIFAC-IL model and two semi-empirical models for IL physical properties. The top 5 IL candidates determined by solving the MINLP problem are subsequently introduced into Aspen Plus for process simulation and economic analysis, which finally identify 1-hexadecyl-methylpiperidinium tricyanomethane([C_(16)MPip][C(CN)_3]) as the best entrainer for this separation. | Zhen Song Xinxin Li He Chao Fan Mo Teng Zhou Hongye Cheng Lifang Chen Zhiwen Qi | 2019 | Green Energy & Environment2019，4，2： | 6 |
| 8 | Effects of artificially induced complete mixing on dissolved organic matter in a stratified source water reservoir显示文摘Naturally complete mixing promotes the spontaneous redistribution of dissolved oxygen(DO),representing an ideal state for maintaining good water quality,and conducive to the biomineralization of organic matter.Water lifting aerators(WLAs)can extend the periods of complete mixing and increase the initial mixing temperature.To evaluate the influence of artificial-induced continuously mixing on dissolved organic matter(DOM)removal performance,the variations of DOM concentrations,optical characteristic,environmental factors were studied after approaching the total mixing status via WLAs operation.During this process,the dissolved organic carbon reduced by 39.18%,whereas the permanganate index decreased by 20.47%.The optical properties indicate that the DOM became more endogenous and its molecular weight decreased.Based on the results of the Biolog Eco Plates,the microorganisms were maintained at a relatively high metabolic activity in the early stage of induced mixing when the mixing temperature was relatively high,whereas DOM declined at a high rate.With the continuous decrease in the water temperature,both the metabolic capacity and the diversity of aerobic microorganisms significantly decreased,and the rate of organic matter mineralization slowed down.The results of this study demonstrate that the artificial induced mixing largely enhanced the removal DOM performance by providing a long period of aerobic conditions and higher initial temperature. | Lingyun Zhao Nan Li Tinglin Huang Haihan Zhang Fan Si Kai Li Yunzhi Qi Fengyao Hua Cheng Huang | 2022 | Journal of Environmental Sciences2022，34，1： | 5 |
| 9 | The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus. | Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang | 2016 | Science China(Life Sciences)2016，59，9： | 5 |
| 10 | The Variation of Stone Cell Content in 236 Germplasms of Sand Pear(Pyrus pyrifolia)and Identification of Related Candidate Genes显示文摘Stone cells have been described to substantially influence pear fruit quality,as lignin and cellulose are the main components of stone cells.However,there are limited studies on the relationship between the variation and molecular basis of stone cells,lignin and cellulose content among different pear varieties.Here,to reveal the variation of stone cell content within different cultivated species,we collected 236 germplasms of sand pear(Pyrus pyrifolia)at 50 days after flower blooming(DAFB),the key stage of stone cell formation.In our results,we measured the content of stone cells,lignin and cellulose and found that these contents ranged from2.82%to 29.00%,8.84%to 55.30%and 11.52%to 30.55%,respectively.Further analysis showed that the variation coefficient of stone cell,lignin and cellulose content was 39.10%,28.03%and 16.71%,respectively.Additionally,a significant correlation between stone cell,lignin and cellulose content were detected,and the correlation coefficient between the contents of stone cell and lignin(0.912)was higher than between the contents of stone cell and cellulose(0.796).Moreover,the average lignin content(29.73%)was higher than the average cellulose content(18.03%)in stone cells in pear fruits,indicating that lignin is the main component of stone cell in pears.Finally,on the basic of the transcriptome data,we identified 10 transcription factors belonging to bHLH,ERF,MYB,and NAC transcript families,which might be involved in lignin formation in stone cells.qRT-PCR experiments verified coincident trends between expression of candidate genes and stone cell content.This research laid foundation for future studies on genetic variation of stone cells in pear fruits and provided important gene resources for stone cell regulation. | Jiaying Zhang Jiaming Li Cheng Xue Runze Wang Mingyue Zhang Kaijie Qi Jing Fan Hongju Hu Shaoling Zhang Jun Wu | 2021 | Horticultural Plant Journal2021，7，2： | 3 |

| 12 | Detection and Initial Response to a Type 2 Vaccine-Derived Poliovirus—Sichuan Province,China,2019显示文摘What is already known about this topic?After the type 2 strain of the live,attenuated poliovirus vaccine was withdrawn globally in 2016,any identification of a type 2 poliovirus is a Public Health Emergency of International Concern.A vaccinederived type 2 poliovirus(VDPV2)was identified in Sichuan,prompting an urgent,comprehensive investigation and response.What is added by this report?Type 2 monovalent,live,attenuated oral poliovirus vaccine(mOPV2)is being used to respond to the numerous VDPV2 outbreaks seen around the world.In contrast,the response in Sichuan used Sabin strain inactivated poliovirus(sIPV)to stop circulation of the VDPV2.In the 6 months following the vaccination response,there have been no VDPV2s detected in Sichuan,despite extensive search.What are the implications for public health practices?Further search for the VDPV2 must continue in order to determine whether transmission has been stopped.The ongoing investigation and response to the Sichuan VDPV2 is providing evidence to the Global Polio Eradication Initiative on managing VDPV2 outbreaks. | Jiushun Zhou Ning Wen Yong Zhang Qi Qi Chunxiang Fan Dongmei Yan Xiaoping Zhu Lixin Hao Shuangli Zhu Yu Liu Xiaozhen Ma Chao Ma Lei Nan Yong Chen Qianli Ma Cheng Wang Kun Deng Lei Cao Ge Shao Xianxiang Ding Hong Yang Zhijie An Lance ERodewald Aiqiang Xu Huaqing Wang Zijian Feng Zundong Yin Xianping Wu Wenbo Xu | 2020 | China CDC weekly2020，2，11： | 3 |
| 13 | Analysis of the relationship between postoperative ophthalmic complications and dialysis time of prekidney transplantation显示文摘AIM:To determine the influence of the dialysis time before kidney transplantation on postoperative ophthalmic comp-lications.· METHODS:One hundred and eighty three patients who were given the follow-up after kidney transplantation were selected,including 124 males and 59 females.The dialysis time before kidney transplantation was(2.9±2.1) years.Among them,there were 93 cases having cadaveric renal transplantation and 90 cases having living relative renal transplantation.The conditions of ophthalmic complications in all the patients after kidney transplantation were investigated and the incidence rate on ophthalmic complications having different dialysis time before kidney transplantation was given Chi-square test and Chi-square linear trend test.· RESULTS:Among 183 patients with kidney transplantation,95 patients(51.9%) had at least one ophthalmic complication and the rest 88 patients(48.1%) had no significant abnormality at the eye region.The most common ophthalmic complications were pinguecula/conjunctival degeneration(31 cases),the following was caligo lentis(24 cases).The main manifestations were grayish white granule and plaque turbidity occurred in posterior capsule at the posterior pole of crystaline lens.The angulus iridocornealis of 5 patients(5.3%) with cataract and glaucoma were all open-angle through the detection by gonioscope.Through visual field examination,there were 2 patients with paracentral scotoma,2 patients with arcuate scotoma and one case with nasal step.· CONCLUSION:The experiments verify that the incidence of glaucomawas relates to the dialysis time before kidney transplantation,and the incidence rate might be higher if the dialysis time is longer. | Yao-Lei Wang Fan Qi Jin-Liang Xie Lin Qi Cheng Zhou Xiang-Rong Zhu Xiang Ding Bo Yang and Peng Jin | 2012 | International Journal of Ophthalmology(English edition)2012，5，3： | 3 |
| 14 | Effect of spacer length on the liquid crystalline property of azobenzene-containing ABA-type triblock copolymers via ATRP显示文摘The effect of flexible spacer length on the liquid crystalline property of ABA-type triblock copolymers containing azobenzene groups was investigated.For the study,the monomers,n-[4-(4-ethoxyphenylazo)phenoxy]alkyl methacrylates with varying methylene groups(n=0,2,6)were used to synthesize a series of azobenzene-containing amphiphilic triblock copolymers PAnC-PEG-PAnC by atom transfer radical polymerization(ATRP).Differential scanning calorimetry(DSC),polarizing optical microscopy(POM),and one-dimensional X-ray diffraction(1D WAXD)have shown that the glass transition temperatures of these copolymers decreased with increasing n,PAOC-PEG-PAOC has no mesophase,while both PA2C-PEG-PA2C and PA6C-PEG- PA6C have a nematic mesophase.These differences derive from the length of spacer groups between the polymer backbone and side-chain LC monomers. | Xin De Tang Long Cheng Gao Xing He Fan Qi Feng Zhou | 2007 | Chinese Chemical Letters2007，18，9： | 2 |
| 15 | Postoperative adjuvant therapy for hepatocellular carcinoma with microvascular invasion显示文摘Hepatocellular carcinoma(HCC)is one of the most lethal tumors in the world.Liver resection(LR)and liver transplantation(LT)are widely considered as radical treatments for early HCC.However,the recurrence rates after curative treatment are still high and overall survival is unsatisfactory.Microvascular invasion(MVI)is considered to be one of the important prognostic factors affecting postoperative recurrence and long-term survival.Unfortunately,whether HCC patients with MVI should receive postoperative adjuvant therapy remains unknown.In this review,we summarize the therapeutic effects of transcatheter arterial chemoembolization,hepatic arterial infusion chemotherapy,tyrosine protein kinase inhibitor-based targeted therapy,and immune checkpoint inhibitors in patients with MVI after LR or LT,aiming to provide a reference for the best adjuvant treatment strategy for HCC patients with MVI after LT or LR. | Jiang Li Fan Yang Jian Li Zhi-Yong Huang Qi Cheng Er-Lei Zhang | 2023 | World Journal of Gastrointestinal Surgery2023，15，1： | 2 |

| 17 | A chromosome-level genome assembly of rugged rose (Rosa rugosa) provides insights into its evolution, ecology, and floral characteristics显示文摘Rosa rugosa,commonly known as rugged rose,is a perennial ornamental shrub.It produces beautiful flowers with a mild fragrance and colorful seed pods.Unlike many other cultivated roses,R.rugosa adapts to a wide range of habitat types and harsh environmental conditions such as salinity,alkaline,shade,drought,high humidity,and frigid temperatures.Here,we produced and analyzed a high-quality genome sequence for R.rugosa to understand its ecology,floral characteristics and evolution.PacBio HiFi reads were initially used to construct the draft genome of R.rugosa,and then Hi-C sequencing was applied to assemble the contigs into 7 chromosomes.We obtained a 382.6Mb genome encoding 39,704 protein-coding genes.The genome of R.rugosa appears to be conserved with no additional whole-genome duplication after the gamma whole-genome triplication(WGT),which occurred~100 million years ago in the ancestor of core eudicots.Based on a comparative analysis of the high-quality genome assembly of R.rugosa and other high-quality Rosaceae genomes,we found a unique large inverted segment in the Chinese rose R.chinensis and a retroposition in strawberry caused by post-WGT events.We also found that floral development-and stress response signaling-related gene modules were retained after the WGT.Two MADS-box genes involved in floral development and the stress-related transcription factors DREB2A-INTERACTING PROTEIN 2(DRIP2)and PEPTIDE TRANSPORTER 3(PTR3)were found to be positively selected in evolution,which may have contributed to the unique ability of this plant to adapt to harsh environments.In summary,the high-quality genome sequence of R.rugosa provides a map for genetic studies and molecular breeding of this plant and enables comparative genomic studies of Rosa in the near future. | Fei Chen Liyao Su Shuaiya Hu Jia-Yu Xue Hui Liu Guanhua Liu Yifan Jiang Jianke Du Yushan Qiao Yannan Fan Huan Liu Qi Yang Wenjie Lu Zhu-Qing Shao Jian Zhang Liangsheng Zhang Feng Chen Zong-Ming(Max)Cheng | 2021 | Horticulture Research2021，8，1： | 2 |

| 19 | Measurement of the neutron total cross section of carbon at the Back-n white neutron beam of CSNS显示文摘To verify the performance of the neutron total cross-sectional spectrometer, the neutron total cross section of carbon is initially measured in the energy range of 1 eV to 20 MeV using the time-of-flight method. The measurement is performed at the Back-n white neutron source with a 76-m time-of-flight path using the China Spallation Neutron Source. A multilayer fast fission chamber with 235U and 238U is employed as the neutron detector. The diameter and thickness of the natural graphite sample are 70 mm and 40 mm, respectively. Signal waveforms are collected using a data acquisition system. Off-line data processing was used to obtain the neutron time-of-flight spectra and transmissions. The uncertainty of the counting statistics is generally approximately 3% for each bin in the energy range of 1–20 MeV. It is determined that the results for the neutron total cross section of carbon obtained using ^235U cells are in good agreement with the results obtained using 238U cells within limits of statistical uncertainty. Moreover, the measured total cross sections show good agreement with the broadening evaluated data. | Xing-Yan Liu Yi-Wei Yang Rong Liu Jie Wen Zhong-Wei Wen Zi-Jie Han Zhi-Zhou Ren Qi An Huai-Yong Bai Jie Bao Ping Cao Qi-Ping Chen Yong-Hao Chen Pin-Jing Cheng Zeng-Qi Cui Rui-Rui Fan Chang-Qing Feng Min-Hao Gu Feng-Qin Guo Chang-Cai Han Guo-Zhu He Yong-Cheng He Yue-Feng He Han-Xiong Huang Wei-Ling Huang Xi-Ru Huang Xiao-Lu Ji Xu-Yang Ji Hao-Yu Jiang Wei Jiang Han-Tao Jing Ling Kang Ming-Tao Kang Bo Li Lun Li Qiang Li Xiao Li Yang Li Yang Li Shu-Bin Liu Guang-Yuan Luan Ying-Lin Ma Chang-Jun Ning Bin-Bin Qi Jie Ren Xi-Chao Ruan Zhao-Hui Song Hong Sun Xiao-Yang Sun Zhi-Jia Sun Zhi-Xin Tan Hong-Qing Tang Jing-Yu Tang Peng-Cheng Wang Qi Wang Tao-Feng Wang Yan-Feng Wang Zhao-Hui Wang Zheng Wang Qing-Biao Wu Xiao-Guang Wu Xuan Wu Li-Kun Xie Han Yi Li Yu Tao Yu Yong-Ji Yu Guo-Hui Zhang Jing Zhang Lin-Hao Zhang Li-Ying Zhang Qing-Min Zhang Qi-Wei Zhang Xian-Peng Zhang Yu-Liang Zhang Zhi-Yong Zhang Ying-Tan Zhao Liang Zhou Zu-Ying Zhou Dan-Yang Zhu Ke-Jun Zhu Peng Zhu | 2019 | Nuclear Science and Techniques2019，30，9： | 2 |
| 20 | Synthesis and characterization of H-type amphiphilic liquid crystalline block copolymers by ATRP显示文摘H-type amphiphilic liquid crystalline block copolymers containing azobenzene were synthesized by atom transfer radical polymerization (ATRP). Macroinitiators prepared by the esterification between poly(ethylene oxide) (PEG) and 2,2-dichloroacetyl chloride were utilized to initiate the polymerization of 6-[4-(4-ethoxyphenylazo)phenoxy]hexyl methacrylate (M6C). The resulting macroinitiators and block copolymers were characterized by 1H NMR, gel permeation chromatography (GPC). Polarizing optical microscopy (POM) and differential scanning calorimetry (DSC) preliminarily revealed the liquid crystalline property of these block copolymers. This series of liquid crystalline block copolymers are promising in some areas, such as optical data storage, optical switch, and molecular devices. | Xin De Tang Long Cheng Gao Xing He Fan Qi Feng Zhou | 2008 | Chinese Chemical Letters2008，19，2： | 2 |
