| 1 | Surveillance, epidemiology, and pathogen spectrum of hand, foot, and mouth disease in mainland of China from 2008 to 2017显示文摘Hand,foot and mouth disease(HFMD)was reported in May 2,2008 to be the 38th legally notifiable disease in China's National Notifiable Disease Reporting and Surveillance System.In order to solve the infection,an extensive three-level HFMD surveillance laboratory network was established.In this study,the framework of that network is assessed and the incidence of HFMD in China from 2008 to 2017 is reported using a descriptive epidemiologic method.During these 10 years,a series of techniques have been widely applied in all the network laboratories.Using information and material obtained from the network,a virus bank and database containing 18,238 viruses were established.Nationally,18,184,834 HFMD cases,including 152,436 severe cases and 3633 fatal cases,were reported in mainland of China.The average annual incidence in the population was 133.99/100,000 people,with a maximum incidence of 205.06/100,000 people in 2014.The incidence and mortality rates of HFMD were the highest in children aged 1–2 years.The numbers of reported cases fluctuated,with a high incidence observed every 2 years.An overall increase in the number of reported cases was also observed throughout the study period.Despite this,the incidence of severe cases and the mortality rate have been decreasing.High-risk regions are located in southern,eastern,and central China.Two peaks of HFMD infection cases were observed annually except for Northeast China.Different proportions of enterovirus serotypes were observed during the studied years.The predominant enterovirus varies from year to year,but the disease severity is always closely related to the specific serotype.EV-A71 is the dominant serotype associated with severe and fatal cases,with constituent ratios of 70.03%and 92.23%,respectively.The studied highly sensitive and efficient surveillance network provides information that is critical for prevention and control of the disease.It is extremely necessary and important to continuously conduct extensive virological surveillance for HFMD. | Tianjiao Ji Taoli Han Xiaojuan Tan Shuangli Zhu Dongmei Yan Qian Yang Yang Song Aili Cui Yan Zhang Naiying Mao Songtao Xu Zhen Zhu Dandan Niu Yong Zhang Wenbo Xu | 2019 | Biosafety and Health2019，1，1： | 26 |
| 2 | Risk factors for proton pump inhibitor refractoriness in Chinese patients with non-erosive reflux disease显示文摘AIM:To analyze risk factors for refractoriness to proton pump inhibitors(PPIs) in patients with non-erosive reflux disease(NERD).METHODS:A total of 256 NERD patients treated with the PPI esomeprazole were enrolled.They were classified into symptom-free and residual symptoms groups according to Quality of Life in Reflux and Dyspepsia(QolRad) scale.All subjects completed questionnaires on psychological status(self-rating anxiety scale;selfrating depression scale) and quality of life scale(Short Form 36).Multivariate analysis was used to determine the predictive factors for PPI responses.RESULTS:According to QolRad,97 patients were confirmed to have residual reflux symptoms,and the remaining 159 patients were considered symptom free.There were no significant differences between the two groups in lifestyle factors(smoking and alcohol consumption),age,Helicobacter pylori infection,and hiatal hernia.There were significant differences between the two groups in relation to sex,psychological distress including anxiety and depression,body mass index(BMI),and irritable bowel syndrome(IBS)(P < 0.05).Logistic regression analysis found that BMI < 23,comorbid IBS,anxiety,and depression were major risk factors for PPI resistance.Symptomatic patients had a lower quality of life compared with symptom-free patients.CONCLUSION:Some NERD patients are refractory to PPIs and have lower quality of life.Residual symptoms are associated with psychological distress,intestinal disorders,and low BMI. | Xiao-Ping Niu Bao-Ping Yu Yun-Dong Wang Zhen Han Shao-Fen Liu Chi-Yi He Guo-Zheng Zhang Wan-Chun Wu | 2013 | World Journal of Gastroenterology2013，19，20： | 18 |
| 3 | Coinfection with influenza A virus enhances SARS-CoV-2 infectivity显示文摘The upcoming flu season in the Northern Hemisphere merging with the current COVID-19 pandemic raises a potentially severe threat to public health.Through experimental coinfection with influenza A virus(IAV)and either pseudotyped or live SARS-CoV-2 virus,we found that IAV preinfection significantly promoted the infectivity of SARS-CoV-2 in a broad range of cell types.Remarkably,in vivo,increased SARS-CoV-2 viral load and more severe lung damage were observed in mice coinfected with IAV.Moreover,such enhancement of SARS-CoV-2 infectivity was not observed with several other respiratory viruses,likely due to a unique feature of IAV to elevate ACE2 expression.This study illustrates that IAV has a unique ability to aggravate SARS-CoV-2 infection,and thus,prevention of IAV infection is of great significance during the COVID-19 pandemic. | Lei Bai Yongliang Zhao Jiazhen Dong Simeng Liang Ming Guo Xinjin Liu Xin Wang Zhixiang Huang Xiaoyi Sun Zhen Zhang Lianghui Dong Qianyun Liu Yucheng Zheng Danping Niu Min Xiang Kun Song Jiajie Ye Wenchao Zheng Zhidong Tang Mingliang Tang Yu Zhou Chao Shen Li Zhou Yu Chen Huan Yan Ke Lan Ke Xu | 2021 | Cell Research2021，31，4： | 16 |
| 4 | COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented. | Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu | 2021 | China CDC weekly2021，3，21： | 16 |
| 5 | Implementation and security analysis of practical quantum secure direct communication显示文摘Rapid development of supercomputers and the prospect of quantum computers are posing increasingly serious threats to the security of communication.Using the principles of quantum mechanics,quantum communication offers provable security of communication and is a promising solution to counter such threats.Quantum secure direct communication(QSDC)is one important branch of quantum communication.In contrast to other branches of quantum communication,it transmits secret information directly.Recently,remarkable progress has been made in proof-of-principle experimental demonstrations of QSDC.However,it remains a technical feat to bring QSDC into a practical application.Here,we report the implementation of a practical quantum secure communication system.The security is analyzed in the Wyner wiretap channel theory.The system uses a coding scheme of concatenation of lowdensity parity-check(LDPC)codes and works in a regime with a realistic environment of high noise and high loss.The present system operates with a repetition rate of 1 MHz at a distance of 1.5 kilometers.The secure communication rate is 50 bps,sufficient to effectively send text messages and reasonably sized files of images and sounds. | Ruoyang Qi Zhen Sun Zaisheng Lin Penghao Niu Wentao Hao Liyuan Song Qin Huang Jiancun Gao Liuguo Yin Gui-Lu Long | 2019 | Light(Science & Applications)2019，8，1： | 15 |

| 7 | Biocompatibility and Immunotoxicology of the Preclinical Implantation of a Collagen-based Artificial Dermal Regeneration Matrix显示文摘Objective Graft rejection, with the possibility of a violent immune response, may be severe and life threatening. Our aim was to thoroughly investigate the biocompatibility and immunotoxicology of collagen-based dermal matrix(DM) before assessment in clinical trials. Methods DM was subcutaneously implanted in BALB/c mice in two doses to induce a potential immune response. The spleen and lymph nodes were assessed for shape, cell number, cell phenotype via flow cytometry, cell activation via CCK8 kit, Annexin V kit, and Ki67 immunostaining. Serum samples were used to measure antibody concentration by enzyme-linked immunosorbent assay. Local inflammation was analyzed by histology and immunohistochemistry staining. Data analysis was performed by one-way ANOVA and non-parametric tests. Results Our data illustrate that the spleen and lymph node sizes were similar between the negative control mice and mice implanted with DM. However, in the high-dose DM(DM-H) group, the total cell populations in the spleen and lymph nodes, T cells and B cells in the spleen had slight increases in prophase, and the low-dose DM(DM-L) group did not display gross abnormities. Moreover, DM-H initiated moderate cell activation and proliferation in the early phase post-immunization, whereas DM-L did not. Neither DM-H nor DM-L implantation noticeably increased IgM and IgG serum concentrations. Examination of the local cellular response revealed only benign cell infiltration and TNF-α expression in slides of DM in the early phase. Conclusion Overall, DM-H may have induced a benign temporary acute immune response post-implantation, whereas DM-L had quite low immunogenicity. Thus, this DM can be regarded as a safe product. | WANG Wei ZHANG Lin SUN Lei SHE Zhen Ding TAN Rong Wei NIU Xu Feng | 2018 | Biomedical and Environmental Sciences2018，31，11： | 14 |

| 9 | Adakites related to subduc-tion in the northern margin of Junggar arc for the Late Paleozoic:Products of slab melting显示文摘Volcanic rocks with adakitic compositional signature have been recognized in the northern margin of ancient Junggar island arc for the Late Paleozoic. These adakites for the early Devonian from the Tuoranggekudouke Group (D1t) are characteristic of high Sr, Sr/Y and (La/Yb)N but low Y, Yb and HREE. Their compositional characteristics are much similar to those of the typical adakites in the world but distinct from those of the normal arc volcanic rocks from the same Group. We conclude that these adakitic volcanic rocks were produced by slab melting during the early period of Paleoasia-ocean lithosphere subduction. This infers that the Paleoasia Ocean in the north Junggar area began a new subduction process in the early Devonian. | Jifeng Xu Houjun Mei Xueyuan Yu Zhenghua Bai Hecai Niu Fanrong Chen Zuoping Zhen Qiang Wang | 2001 | Chinese Science Bulletin2001，46，15： | 11 |

| 11 | Amentoflavone protects hippocampal neurons: anti-inflammatory, antioxidative, and antiapoptotic effects显示文摘Amentoflavone is a natural biflavone compound with many biological properties, including anti-inflammatory, antioxidative, and neuroprotective effects. We presumed that amentoflavone exerts a neuroprotective effect in epilepsy models. Prior to model establishment, mice were intragastrically administered 25 mg/kg amentoflavone for 3 consecutive days. Amentoflavone effectively prevented pilocarpine-induced epilepsy in a mouse kindling model, suppressed nuclear factor-κB activation and expression, inhibited excessive discharge of hippocampal neurons resulting in a reduction in epileptic seizures, shortened attack time, and diminished loss and apoptosis of hippocampal neurons. Results suggested that amentoflavone protected hippocampal neurons in epilepsy mice via anti-inflammation, antioxidation, and antiapoptosis, and then effectively prevented the occurrence of seizures. | Zhen Zhang Tao Sun Jian-guo Niu Zhen-quan He Yang Liu Feng Wang | 2015 | Neural Regeneration Research2015，10，7： | 9 |
| 12 | A Novel Surgery Classification for Endoscopic Approaches to Middle Ear Cholesteatoma显示文摘This study aimed to develop a novel surgery classification for an endoscopic approach to middle ear cholesteatoma.We retrospectively analyzed the surgical approaches and outcomes of patients with middle ear cholesteatoma.Middle ear cholesteatoma surgeries were divided into four types and two special types as follows:type I,attic retraction pocket,which only requires tympanostomy tube placement or retraction pocket resection and cartilage reconstruction;typeⅡ,cholesteatoma which is limited to the attic or in which endoscopy can confirm complete removal of mastoid cholesteatoma lesions,including type Ⅱa,requiring only use of a curette,and type Ⅱ b,requiring use of an electric drill or chisel;type Ⅲ,cholesteatoma not limited to the attic,in which endoscopy cannot confirm complete removal of mastoid cholesteatoma lesions,requiring the combined use of endoscope and microscope to perform endoscopic tympanoplasty and'Canal Wall Up'mastoidectomy;type Ⅳ,extensive involvement of mastoid cavity cholesteatoma lesions and/or cases with a potential risk of complications,removal of which can only be performed under a microscope for'Canal Wall Down'mastoidectomy.In addition,there were two special types:'difficult external auditory canal'and congenital cholesteatoma in children.In our system,type I and type U middle ear cholesteatoma surgery was completely performed under an endoscope alone.However,estimating the extent of the lesions,determining the choice of mastoid opening and reestablishing ventilation are the key points for an endoscopic approach to middle ear cholesteatoma.The classification of endoscopic middle ear cholesteatoma surgery may benefit the selection of surgical indications. | Yu SUN En-hao WANG Jin-tao YU Gang ZHONG Li-xin ZHU-Yi WANG Niu XUN Hong YU Wen ZHOU Zhen XIE Kun ZHANG Guo-run FAN Yi ZHONG Hong-jun XIAO Wei-jia KONG | 2020 | Current Medical Science2020，40，1： | 8 |

| 15 | The Research on 220GHz Multicarrier High-Speed Communication System显示文摘This paper presents our investigation into a 220 GHz multicarrier highspeed communication system based on solid state transceivers.The proposed system has eased the demand of high sampling rate analog-to-digital converter(ADC)by providing several signal carriers in microwave band and converting them to 220 GHz channel.The system consists of a set of 220 GHz solid-state transceiver with 2 signal carriers,two basebands for 4 GSPS ADCs.It has achieved 12.8 Gbps rate real-time signal transmission using 16QAM modulation over a distance of 20 m without any other auxiliary equipment or test instruments.The baseband algorithm overcomes the problem of frequency difference generates by non-coherent structure,which guarantees the feasibility of long-distance transmission application.Most importantly,the proposed system has already carried out multi-channel 8K video parallel transmission through switch equipment,which shows the multicarrier high-speed communication system in submillimeter wave has great application prospects.To the best of the authors’knowledge,this is the first all-solid-state electronics multicarrier communication system in submillimeter and terahertz band. | Zhongqian Niu Bo Zhang Jiale Wang Ke Liu Zhi Chen Ke Yang Zhen Zhou Yong Fan Yaohui Zhang Dongfeng Ji Yinian Feng Yang Liu | 2020 | China Communications2020，17，3： | 5 |
| 16 | Perioperative rh-endostatin with chemotherapy improves the survival of conventional osteosarcoma patients: a prospective non-randomized controlled study显示文摘Objective: Anti-angiogenic drugs are an emerging treatment option against malignant tumors. The aim of this study was to determine whether the addition of perioperative rh-endostatin to chemotherapy could improve the probability of distant metastasis-free survival(DMFS) and overall survival(OS) in patients newly diagnosed with non-metastatic conventional osteosarcoma.Methods: This was a controlled non-randomized clinical study that included 388 patients without clinically detectable metastatic disease enrolled from January 2008 to April 2012. The control treatment group had 272 patients; 180 were male and 92, female,with a median age of 17 years. The treatment group had 58 patients; 36 were male and 22, female, with a median age of 16 years.The control group received preoperative chemotherapy followed by surgery and postoperative chemotherapy. The treatment group received 4 cycles of rh-endostatin perioperatively in addition to chemotherapy as per the control group. Patients were followed up from 6-101 months with a median follow-up period of 50.2 months.Results: The 5-year DMFS of the control group(61%) was significantly lower than that of the rh-endostatin group(79%)(P = 0.013). The 5-year OS of the control group(74%) was significantly lower than that of the rh-endostatin treatment group(87%)(P = 0.029). No difference in adverse drug reactions was found between these 2 groups.Conclusions: The addition of perioperative rh-endostatin to chemotherapy could significantly improve the DMFS and OS of patients with non-metastatic osteosarcoma. | Hairong Xu Zhen Huang Yuan Li Qing Zhang Lin Hao Xiaohui Niu | 2019 | Cancer Biology & Medicine2019，16，1： | 5 |
| 17 | Study on structure-activity relationship of mutation-dependent herbicide resistance acetohydroxyacid synthase through 3D-QSAR and mutation显示文摘Seventy-four sulfonylureas were synthesized and tested for their inhibitory activity against the whole enzyme of E. coli acetohydroxyacid synthase (AHAS, EC 2.2.1.6) isoenzyme II, and 3D-QSAR analyses were performed based on these inhibitory activities. The binding conformation of chlorimuron-ethyl, a commercial herbicide of AHAS, in the crystal structure of AHAS complex was extracted and used as template to build the initial three-dimensional structure of other sulfonylureas, and then all structures were fully geometry optimized. After systematic optimization of the alignment rule, molecular orienta- tion, grid space and attenuation factor, two satisfactory models with excellent performances (CoMFA: q2 = 0.735, r2 = 0.954, n = 7, r 2 pred = 0.832; CoMSIA: q2 = 0.721, r2 = 0.913, n = 8, r 2pred = 0.844) were estab- lished. By mapping the 3D contour maps of CoMFA and CoMSIA models into the possible inhibitory active site in the crystal structure of catalytic subunit of yeast AHAS, a plausible binding model for AHAS, with best fit QSAR in the literature so far, was proposed. Moreover, the results of 3D-QSAR were further utilized to interpret resistance of site-directed mutants. A relative activity index (RAI) for AHAS enzyme mutant was defined for the first time to relate the 3D-QSAR and resistance of mutants. This study, for the first time, demonstrated that combination of 3D-QSAR and enzyme mutation can be used to decipher the molecular basis of ligand-receptor interaction mechanism. This study refined our understanding of the ligand-receptor interaction and resistance mechanism in AHAS-sulfonylurea system, and provided basis for designing new potent herbicides to combat the herbicide resistance. | YU ZhiHong NIU CongWei BAN ShuRong WEN Xin XI Zhen | 2007 | Chinese Science Bulletin2007，52，14： | 5 |

| 19 | Impact of 5-Fu/oxaliplatin on mouse dendritic cells and synergetic effect with a colon cancer vaccine显示文摘Objective: The aim of the present study was to investigate the effects of 5-fluorouracil(5-Fu) and oxaliplatin on the function and activation pathways of mouse dendritic cells(DCs), and to clarify whether 5-Fu/oxaliplatin combined with the CD1d-MC38/α-galactosylceramide(α-GC) tumor vaccine exhibits synergistic effects on the treatment of colon cancer in mice.Methods: The combination of the Toll like receptor(TLR) ligands and/or 5-Fu/oxaliplatin was added into myeloid-derived DCs in vitro culture. DC phenotypic changes were detected by flow cytometry, and the secretion of DC cytokines was detected by cytometric bead array(CBA). A MC38 mouse colon cancer model was constructed and the DCs were isolated from the spleen, tumor tissue and lymph nodes following intraperitoneal injection of 5-Fu/oxaliplatin. The cell phenotypes were detected by flow cytometry. The tumor infiltrating leukocytes,splenocytes and lymph node cells were co-cultured with the dead MC38 tumor cells, and the secretion levels of interferon-γ(IFN-γ) were detected. 5-Fu/oxaliplatin combined with our previously developed CD1d-MC38/α-GC tumor vaccine was used to inhibit the growth of MC38 colon cancer in mice, and the tumor growth rate and survival time were recorded.Results: 5-Fu/oxaliplatin exerted no significant effect on the expression of the stimulating phenotypes of DCs in vitro, while it could reduce the expression of programmed death ligand 1/2(PD-L1/L2) and promote interleukin-12(IL-12) secretion by DCs. Furthermore 5-Fu/oxaliplatin was beneficial to the differentiation of T-helper 1(Th1) cells. 5-Fu/oxaliplatin further enhanced the stimulating phenotypic expression of DCs in tumor bearing mice, decreased PD-L1/L2 expression, and specifically activated the lymphocytes. The CD1d-MC38/α-GC tumor vaccine combined with 5-Fu/oxaliplatin could exert a synergistic role that resulted in a significant delay of the tumor growth rate, and an increase in the survival time of tumor bearing mice.Conclusions: 5-Fu/oxaliplatin decreased the expression of the DC inhibitory phenotypes PD-L1/L2, promoted DC phenotypic maturation in tumor bearing mice, activated the lymphocytes of tumor bearing mice, and exerted synergistic effects with the CD1d-MC38/α-GC colon cancer tumor vaccine. | Xinqiang Hong Tiangeng Dong Tuo Yi Jianwei Hu Zhen Zhang Shengli Lin Weixin Niu | 2018 | Chinese Journal of Cancer Research2018，30，2： | 4 |
| 20 | Back-n white neutron source at CSNS and its applications显示文摘Back-streaming neutrons from the spallation target of the China Spallation Neutron Source(CSNS)that emit through the incoming proton channel were exploited to build a white neutron beam facility(the so-called Back-n white neutron source),which was completed in March 2018.The Back-n neutron beam is very intense,at approximately 29107 n/cm2/s at 55 m from the target,and has a nominal proton beam with a power of 100 kW in the CSNS-I phase and a kinetic energy of 1.6 GeV and a thick tungsten target in multiple slices with modest moderation from the cooling water through the slices.In addition,the excellent energy spectrum spanning from 0.5 eV to 200 MeV,and a good time resolution related tothe time-of-flight measurements make it a typical white neutron source for nuclear data measurements;its overall performance is among that of the best white neutron sources in the world.Equipped with advanced spectrometers,detectors,and application utilities,the Back-n facility can serve wide applications,with a focus on neutron-induced cross-sectional measurements.This article presents an overview of the neutron beam characteristics,the experimental setups,and the ongoing applications at Backn. | Jing-Yu Tang Qi An Jiang-Bo Bai Jie Bao Yu Bao Ping Cao Hao-Lei Chen Qi-Ping Chen Yong-Hao Chen Zhen Chen Zeng-Qi Cui Rui-Rui Fan Chang-Qing Feng Ke-Qing Gao Xiao-Long Gao Min-Hao Gu Chang-Cai Han Zi-Jie Han Guo-Zhu He Yong-Cheng He Yang Hong Yi-Wei Hu Han-Xiong Huang Xi-Ru Huang Hao-Yu Jiang Wei Jiang Zhi-Jie Jiang Han-Tao Jing Ling Kang Bo Li Chao Li Jia-Wen Li Qiang Li Xiao Li Yang Li Jie Liu Rong Liu Shu-Bin Liu Xing-Yan Liu Ze Long Guang-Yuan Luan Chang-Jun Ning Meng-Chen Niu Bin-Bin Qi Jie Ren Zhi-Zhou Ren Xi-Chao Ruan Zhao-Hui Song Kang Sun Zhi-Jia Sun Zhi-Xin Tan Xin-Yi Tang Bin-Bin Tian Li-Jiao Wang Peng-Cheng Wang Zhao-Hui Wang Zhong-Wei Wen Xiao-Guang Wu Xuan Wu Li-Kun Xie Xiao-Yun Yang Yi-Wei Yang Han Yi Li Yu Tao Yu Yong-Ji Yu Guo-Hui Zhang Lin-Hao Zhang Qi-Wei Zhang Xian-Peng Zhang Yu-Liang Zhang Zhi-Yong Zhang Lu-Ping Zhou Zhi-Hao Zhou Ke-Jun Zhu 无 | 2021 | Nuclear Science and Techniques2021，32，1： | 4 |
