| 1 | A life support-based comprehensive treatment regimen dramatically lowers the in-hospital mortality of patients with fulminant myocarditis: a multiple center study显示文摘Fulminant myocarditis(FM) has unacceptable high mortality. This study aimed to evaluate the therapeutic efficacy of a life support-based comprehensive treatment regimen(LSBCTR), a completely novel treatment regimen, for FM. A total of 169 FM patients recruited from January 2008 to December 2018 were divided into two groups: patients receiving LSBCTR(81 cases),which includes(i) mechanical life support(positive pressure respiration, intra-aortic balloon pump with or without extracorporeal membrane oxygenation),(ii) immunomodulation therapy using sufficient doses of glucocorticoids and immunoglobulins, and(iii) application of neuraminidase inhibitors, and those receiving conventional treatment(88 cases). The endpoints were in-hospital death and heart-transplantation. Of all the population, 44 patients(26.0%) died in hospitals. Inhospital mortality was 3.7%(3/81) for LSBCTR group and 46.6%(41/88) for traditional treatment(P<0.001). Early application of LSBCTR, mechanical life support, neuraminidase inhibitors, and immunomodulation therapy significantly contributed to reduction in in-hospital mortality. This study describes a novel treatment regimen for FM patients that dramatically reduces inhospital mortality. Its generalization and clinical application will efficiently save lives although further optimization is needed.This study offers an insight that virus infection induced inflammatory waterfall results in cardiac injury and cardiogenic shock and is the therapeutic target. | Sheng Li Shengyong Xu Chenze Li Xiao Ran Guanglin Cui Mengying He Kun Miao Chunxia Zhao Jiangtao Yan Rutai Hui Ning Zhou Yan Wang Jiangang Jiang Jing Zhang Daowen Wang | 2019 | Science China(Life Sciences)2019,62,3: | 43 |
| 2 | Chinese expert consensus statement on the diagnosis and treatment of fulminant myocarditis显示文摘Fulminant myocarditis is primarily caused by infection with any number of a variety of viruses. It arises quickly, progresses rapidly, and may lead to severe heart failure or circulatory failure presenting as rapid-onset hypotension and cardiogenic shock,with mortality rates as high as 50%–70%. Most importantly, there are no treatment options, guidelines or an expert consensus statement. Here, we provide the first expert consensus, the Chinese Society of Cardiology Expert Consensus Statement on the Diagnosis and Treatment of Fulminant Myocarditis, based on data from our recent clinical trial(NCT03268642). In this statement, we describe the clinical features and diagnostic criteria of fulminant myocarditis, and importantly, for the first time,we describe a new treatment regimen termed life support-based comprehensive treatment regimen. The core content of this treatment regimen includes(i) mechanical life support(applications of mechanical respirators and circulatory support systems,including intraaortic balloon pump and extracorporeal membrane oxygenation),(ii) immunological modulation by using sufficient doses of glucocorticoid, immunoglobulin and(iii) antiviral reagents using neuraminidase inhibitor. The proper application of this treatment regimen may and has helped to save the lives of many patients with fulminant myocarditis. | Daowen Wang Sheng Li Jiangang Jiang Jiangtao Yan Chunxia Zhao Yan Wang Yexin Ma Hesong Zeng Xiaomei Guo Hong Wang Jiarong Tang Houjuan Zuo Li Lin Guanglin Cui Section of Precision Medicine Group of Chinese Society of Cardiology,Editorial Board of Chinese Journal of Cardiology &Working Group of Adult Fulminant Myocarditis | 2019 | Science China(Life Sciences)2019,62,2: | 18 |

| 5 | Development of high-temperature superconducting filters operating at temperatures above 90 K显示文摘This paper represents the development of a high temperature superconducting (HTS) filter, the highest operating temperature of which is up to 93 K. The filter is designed for S band with 4% fractional bandwidth and fabricated using thallium-barium-calcium-copper oxide (Tl2Ba2CaCu2O8) thin films. At 93 K, the measurements of the filter show that the insertion loss in the passband is less than 0.22 dB, the return loss is better than 20 dB, and the out-of-band rejection is more than 80 dB. The analysis on the characteristics of the filter operating at different temperatures shows that the filter can work well at temperatures around 90 K. The temperature of 93 K is the highest among the previous reports for HTS filters. The result reported in this paper is significant for HTS filters to be used in the field of microwave communication requiring high sensitivity. | XIA HouHai ZHOU ChunXia ZUO Tao HE Ming JI Lu ZHOU TieGe ZHAO XinJie FANG Lan YAN ShaoLin | 2009 | Chinese Science Bulletin2009,54,19: | 9 |
| 6 | High-Resolution Genome-wide Association Study Identifies Genomic Regions and Candidate Genes for Important Agronomic Traits in Wheat显示文摘Wheat(Triticum aestivum)is a major staple food crop worldwide.Genetic dissection of important agronomic traits is essential for continuous improvement of wheat yield to meet the demand of the world's growing population.We conducted a large-scale genome-wide association study(GWAS)using a panel of 768 wheat cultivars that were genotyped with 327609 single-nucleotide polymorphisms generated by genotyping-by-sequencing and detected 395 quantitative trait loci(QTLs)for 12 traits under 7 environments.Among them,273 QTLs were delimited to≤1.0-Mb intervals and 7 of them are either known genes(Rht-D,Vrn-B1,and Vrn-D1)that have been cloned or known QTLs(TaGA2ox8,APO1,TaSus1-7B,and Rht12)that were previously mapped.Eight putative candidate genes were identified for three QTLs that enhance spike seed setting and grain size using gene expression data and were validated in three bi-parental populations.Protein sequence analysis identified 33 putative wheat orthologs that have high identity with rice genes in QTLs affecting similar traits.Large r^2 values for additive effects observed among the QTLs for most traits indicated that the phenotypes of these identified QTLs were highly predictable.Results from this study demonstrated that significantly increasing GWAS population size and marker density greatly improves detection and identification of candidate genes underlying a QTL,solidifying the foundation for large-scale QTL fine mapping,candidate gene validation,and developing functional markers for genomics-based breeding in wheat. | Yunlong Pang Chunxia Liu Danfeng Wang Paul St.Amand Amy Bernardo Wenhui Li Fang He Linzhi Li Liming Wang Xiufang Yuan Lei Dong Yu Su Huirui Zhang Meng Zhao Yunlong Liangi Hongze Jia Xitong Shen Yue Lu Hongming Jiang Yuye Wu Anfei Li Honggang Wang Lingrang Kong Guihua Bai Shubing Liu | 2020 | Molecular Plant2020,13,9: | 8 |
| 7 | The use of fire at Zhoukoudian:evidence from magnetic susceptibility and color measurements显示文摘In order to provide direct evidence for the use of fire by humans at Locality 1,Zhoukoudian,we examine the burnt and unburnt sediments of newly excavated area in Layer 4 by detailed measurements of magnetic susceptibility,color,and diffuse reflectance spectrum.Results show that the magnetic susceptibility and redness of the burnt sediments are remarkably higher than those of other areas on the same level:up to*22 times for magnetic susceptibility and*3 times for redness of those of the adjacent unburnt sediments.Fine-grained(superparamagnetic/stable single-domain)magnetite and hematite grains make dominant contributions to the distinctly high values of magnetic susceptibility and redness in the burnt sediments.Diffuse reflectance spectroscopy results show that the burnt sediments contain more hematite than those of other areas and localities 2 and 3.High-temperature magnetic susceptibility measurements demonstrate that the burnt sediments have been heated above 700°C.Those changes in low-frequency magnetic susceptibility and redness are impossibly resulted from natural fires,thus most likely signaling the human activities of controlled use of fire.However,further work is needed to confirm whether or not these heat-affected sediments were produced in situ. | Yan Zhang Zhengtang Guo Chenglong Deng Shuangquan Zhang Haibin Wu Chunxia Zhang Junyi Ge Deai Zhao Qin Li Yang Song Rixiang Zhu | 2014 | Chinese Science Bulletin2014,59,10: | 6 |
| 8 | Uncommon EGFR mutations in a cohort of Chinese NSCLC patients and outcomes of first-line EGFR-TKIs and platinum-based chemotherapy显示文摘Objective: Data on the clinical activity of epidermal growth factor receptor(EGFR) tyrosine kinase inhibitors(TKIs) in patients with non-small-cell lung cancer(NSCLC) and uncommon EGFR mutations remain insufficient.This study aimed to investigate the effect of first-line EGFR-TKIs or platinum-based chemotherapy in NSCLC patients with uncommon EGFR mutations.Methods: We retrospectively enrolled 504 patients with EGFR-mutant NSCLC.The clinical characteristics and treatment outcomes were collected and compared between patients with common and uncommon EGFR-mutant NSCLC.Results: Seventy patients(13.9%) harboring uncommon EGFR mutations were included.Thirty of these patients received EGFR-TKIs and 40 received platinum-based chemotherapy as first-line therapy.The objective response rate(ORR) and median progression-free survival(m PFS) of patients treated with TKIs in the uncommon mutation group was significantly inferior to that in the common mutation group(ORR: 23.3% vs.51.8%,P=0.003; m PFS:7.1 vs.10.9 months,P<0.001).In the uncommon group,m PFS was similar between first-line EGFR-TKIs treatment and platinum-based chemotherapy(7.1 vs.6.1 months,P=0.893).In patients with EGFR G719 X or L861 Q mutations,the m PFS was longer in the first-line EGFR-TKIs treatment group than in the chemotherapy group,but the difference was not statistically significant(G719 X: 8.2 vs.5.8 months,P=0.061; L861 Q: 7.6 vs.4.1 months,P=0.872).Multivariate analyses identified adenocarcinoma(P=0.003) as the independent predictive factor for PFS in patients with uncommon EGFR mutations who were treated with first-line EGFR-TKIs.Conclusions: The current study demonstrated that the effect of first-line EGFR-TKIs was similar to that of platinum-based chemotherapy in patients with uncommon EGFR-mutant NSCLC.Adenocarcinoma was the independent predictive factor for PFS in uncommon EGFR-mutant NSCLC patients treated with first-line EGFRTKIs. | Jinpeng Shi Hui Yang Tao Jiang Xuefei Li Chao Zhao Limin Zhang Sha Zhao Xiaozhen Liu Yijun Jia Yan Wang Lei Xi Shijia Zhang Chunxia Su Shengxiang Ren Caicun Zhou | 2017 | Chinese Journal of Cancer Research2017,29,6: | 6 |
| 9 | A study on service capacity of primary medical and health institutions for cervical cancer screening in urban and rural areas in China显示文摘Objective: To provide a decision-making basis for sustainable and effective development of cervical cancer screening.Methods: This cross-sectional study assesses the service capacity to conduct cervical cancer screening with a sample of 310 medical staff, medical institutions and affiliated township health centers from 20 countylevel/district-level areas in 14 Chinese provinces in 2016.Results: The county-level/district-level institutions were the main prescreening institutions for cervical cancer screening. More medical staff have become engaged in screening, with a significantly higher amounts in urban than in rural areas(P<0.05). The number of human papillomavirus(HPV) testers grew the fastest(by 225% in urban and 125% in rural areas) over the course of the project. HPV testing took less time than cytology to complete the same number of screening tasks in both urban and rural areas. The proportion of mid-level professionals was the highest among the medical staff, 40.0% in urban and 44.7% in rural areas(P=0.406), and most medical staff had a Bachelor’s degree, accounting for 76.3% in urban and 52.0% in rural areas(P<0.001). In urban areas, 75.0% were qualified medical staff, compared with 68.0% in rural areas, among which the lowest proportion was observed for rural cytology inspectors(22.7%). The medical equipment for cervical pathology diagnosis in urban areas was better(P<0.001). HPV testing equipment was relatively adequate(typing test equipment was 70% in urban areas, and non-typing testing equipment was 70% in rural areas).Conclusions: The service capacity of cervical cancer screening is insufficient for the health needs of the Chinese population. HPV testing might be an optimal choice to fill the needs of cervical cancer screening given current Chinese medical health service capacity. | Yang Li Li Ma Chunxia Yang Zhangya Chen Yuqian Zhao Le Dang Jinghe Lang Youlin Qiao | 2019 | Chinese Journal of Cancer Research2019,31,5: | 5 |
| 10 | Comparison of nonhuman primates identified the suitable model for COVID-19显示文摘Identification of a suitable nonhuman primate(NHP)model of COVID-19 remains challenging.Here,we characterized severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection in three NHP species:Old World monkeys Macaca mulatta(M.mulatta)and Macaca fascicularis(M.fascicularis)and New World monkey Callithrix jacchus(C.jacchus).Infected M.mulatta and M.fascicularis showed abnormal chest radiographs,an increased body temperature and a decreased body weight.Viral genomes were detected in swab and blood samples from all animals.Viral load was detected in the pulmonary tissues of M.mulatta and M.fascicularis but not C.jacchus.Furthermore,among the three animal species,M.mulatta showed the strongest response to SARS-CoV-2,including increased inflammatory cytokine expression and pathological changes in the pulmonary tissues.Collectively,these data revealed the different susceptibilities of Old World and New World monkeys to SARS-CoV-2 and identified M.mulatta as the most suitable for modeling COVID-19. | Shuaiyao Lu Yuan Zhao Wenhai Yu Yun Yang Jiahong Gao Junbin Wang Dexuan Kuang Mengli Yang Jing Yang Chunxia Ma Jingwen Xu Xingli Qian Haiyan Li Siwen Zhao Jingmei Li Haixuan Wang Haiting Long Jingxian Zhou Fangyu Luo Kaiyun Ding Daoju Wu Yong Zhang Yinliang Dong Yuqin Liu Yinqiu Zheng Xiaochen Lin Li Jiao Huanying Zheng Qing Dai Qiangming Sun Yunzhang Hu Changwen Ke Hongqi Liu Xiaozhong Peng | 2020 | Signal Transduction and Targeted Therapy2020,5,1: | 5 |
| 11 | New Layered SOA-Based Architecture for Multi-robots Cooperative Online SLAM显示文摘A new layered multi-robots architecture for cooperative online simultaneous localization and mapping based on Service-oriented architecture(SOA) is proposed. This architecture is constructed by the concepts of service-oriented and loosely coupled center scheduling.These methods make robots' underlying function realization be transparent in cooperation and avoid the impact affected by robot heterogeneous characteristics, which will be beneficial to the system construction, expansion, restructuring and maintenance. All data packages follow the SOA unified data format, which can avoid the impact affected by sensor heterogeneous characteristics. The point to point serving model reduces the path of data transmission which can improve the timeliness of the system. All of these features can satisfy the requirements of multi-robots cooperative online SLAM. The simulation results show the feasibility, applicability and practicability of this architecture. | CAI Yunfei TANG Zhenmin ZHAO Chunxia | 2014 | Chinese Journal of Electronics2014,23,1: | 5 |
| 12 | Economic evaluation of cervical cancer screening strategies in urban China显示文摘Objective:This study evaluated the feasibility of different cervical cancer screening strategies in urban China.Methods:A Markov model was constructed to simulate a hypothetical cohort of 100,000 females aged 30-59 years in a 20-year period.Screening strategies included liquid-based cytology(LBC)every three years,human papillomavirus(HPV)DNA testing every three and five years,respectively,and a combination of HPV DNA testing and LBC(HPV+LBC)every three and five years,respectively.Model outcomes included cumulative incidence over 20 years,cumulative risk of cervical cancer,costs,life year saved(LYS),quality-adjusted life years(QALYs)and benefits.The cost-effectiveness ratios(CERs),incremental cost-effectiveness ratios(ICERs),costutility ratios(CURs),and benefit-cost ratios(BCRs)were used as outcomes in the health economic evaluation analysis.Univariate sensitivity analyses were performed to examine the stability of the results.Results:The cumulative incidence of the five screening strategies ranged from 833.02 to 1,158.07 cases per100,000 females.HPV DNA testing was most effective in reducing the cumulative risk of cervical cancer,saving life years and QALYs and gaining benefits.The CERs of HPV DNA testing every three and five years,and LBC every three years were considered to be very cost-effective if they were below China's GDP per capita.The CERs of HPV+LBC were considered to be cost-effective if they were below three times GDP per capita.The incremental cost-effectiveness analysis showed that HPV DNA testing every three and five years,LBC every three years and HPV+LBC every five years were dominant strategies.Conclusions:The findings of this study indicated that HPV DNA testing every five years or LBC every three years should be recommended in urban China. | Li Ma Yuying Wang Xiaohong Gao Yi Dai Yu Zhang Zhaojing Wang Xiaoxia Wang Limin Wang Jing Jiang Xinhua Jing Chunxia Yang Fanghui Zhao Jinghe Lang Youlin Qiao | 2019 | Chinese Journal of Cancer Research2019,31,6: | 4 |
| 13 | Near-infrared luminescent Nd^(3+)/Yb^(3+)-codoped metal-organic framework for ratiometric temperature sensing in physiological range显示文摘Self-calibrating luminescent thermometry employing luminescence within the optical transparency windows provides a promising prospect for temperature measurement in the biological fields.In this work,a new Nd^(3+)/Yb^(3+)-codoped metal-organic framework Nd_(0.95)Yb_(0.05)BPTC showing threedimensional anionic network,obtained by reacting ligand[1,1’-biphenyl]-3,3’,5,5’-tetracarboxylic acid(H4BPTC)with Nd^(3+)and Yb^(3+)ions under solvothermal conditions,is reported.Upon 808 nm photoexcitation,Nd_(0.95)Yb_(0.05)BPTC simultaneously emits the characteristic near-infrared luminescence of Nd^(3+)and Yb^(3+)ions based on the efficient energy transfer from Nd^(3+)to Yb^(3+)ions.In addition,the emission intensity ratio of Yb^(3+)and Nd^(3+)shows good exponential-like response to temperature in the physiological range of 293-323 K.The feature properties of Nd_(0.95)Yb_(0.05)BPTC include near-infrared absorption and emission,favorable temperature sensitivity and accurate temperature uncertainty,as well as good chemical stability,making such system useful in biomedical applications. | Chao Gu Yanyun Ding Xinghua Quan Mengyao Gong Jiulong Yu Dian Zhao Chunxia Li | 2021 | Journal of Rare Earths2021,39,9: | 4 |
| 14 | Development of X-band high temperature superconducting filters显示文摘A synthesized design method is proposed to design microstrip band-pass filters. The impact of the box structure to the filter performance is considered besides the structure of microstrip. An X-band high temperature superconducting (HTS) microstrip filter for deep space network is designed using this method. The six-pole microstrip band-pass filter at frequency of 9500 ± 500 MHz is realized using TBCCO HTS thin film grown on 0.5 mm thick LaAlO3 substrate. The filter shows very high rejection of 90 dB in the stopband and extremely low loss less than 0.2 dB. The measured results are close to the simulated results without any post-production tuning. | ZHOU ChunXia XIA HouHai ZUO Tao ZHAO XinJie FANG Lan YAN ShaoLin | 2010 | Chinese Science Bulletin2010,55,2: | 3 |

| 16 | LncRNA NORAD promotes the progression of myocardial infarction by targeting the miR-22-3p/PTEN axis显示文摘NORAD is a newly identified long non-coding RNA(lncRNA)that plays an important role in cancers.NORAD has been found to be highly expressed in the mouse model of acute myocardial infarction(AMI).However,the role of NORAD in the regulation of AMI remains unknown.In the present study,we aimed to investigate the function of NORAD in AMI and explore the potential regulatory mechanisms.A mouse model of AMI was established and NORAD was knocked-down.The infarcted size of heart tissues and the cardiac function were evaluated.In addition,two cardiomyocyte cell lines were treated with hypoxia/re-oxygenation(H/R)to mimic AMI in vitro.Luciferase reporter assay,RNA pull-down assay,fluorescence in situ hybridization,qRT-PCR,and western blot analysis were performed.Apoptotic cells and the levels of L-lactate dehydrogenase(LDH)and malondialdehyde(MDA)were detected.Our results show that downregulation of NORAD efficiently attenuates heart damage in the AMI mouse model.NORAD interacts with miR-22-3p.Knock-down of NORAD inhibits H/R-induced cell apoptosis and reduces LDH and MDA levels,while its effects are abolished by miR-22-3p inhibitor.MiR-22-3p interacts with PTEN and inhibits its expression.Overexpression of miR-22-3p inhibits H/R-induced cell apoptosis and reduces LDH and MDA levels,while its effects are abolished by overexpression of PTEN.Finally,overexpression of NORAD inhibits the AKT/mTOR signaling pathway,and its effects are attenuated by overexpression of miR-22-3p.Taken together,our study reveals that NORAD promotes the progression of AMI by regulating the miR-22-3p/PTEN axis,and the AKT/mTOR signaling may also be involved in the regulatory processes. | Chunxia Li Lihui Zhang Xingpeng Bu Guofang Chu Xiaofang Zhao Yaru Liu | 2022 | Acta Biochimica et Biophysica Sinica2022,54,4: | 3 |

| 19 | Gelation behavior of Antheraea pernyi silk fibroin显示文摘The sol-gel transition behavior of Antherae pernyi silk fibroin(Ap-SF) has not been systematically investigated.In this work,the influence of environmental temperature,pH,the concentration of Ap-SF,K+ and Ca2+ on the gelation time,and the structural changes of Ap-SF in sol-gel transformation were studied.The results indicated that the gelation time of the Ap-SF aqueous solution decreased with the increase of the Ap-SF concentration and environmental temperature.The sol-gel transformation of Ap-SF was much more rapid than that of Bombyx mori silk fibroin under the same conditions.The Ap-SF was sensitive to changes in the concentration of Ca2+ and K+.Upon gelation,the random coil structure of the Ap-SF was significantly transformed into the β-sheet structure. | YAN ShuQin,ZHAO ChunXia,WU XiuFang,ZHANG Qiang & LI MingZhong National Engineering Laboratory for Modern Silk College of Textile and Clothing Engineering,Soochow University,Suzhou 215123,China | 2010 | Science China Chemistry2010,53,3: | 2 |
| 20 | AATYK is a Novel Regulator of Oligodendrocyte Differentiation and Myelination显示文摘Oligodendrocytes(OLs) are myelinating glial cells that form myelin sheaths around axons to ensure rapid and focal conduction of action potentials. Here, we found that an axonal outgrowth regulatory molecule, AATYK(apoptosis-associated tyrosine kinase), was up-regulated with OL differentiation and remyelination. We therefore studied its role in OL differentiation. The results showed that AATYK knockdown inhibited OL differentiation and the expression of myelin genes in vitro. Moreover, AATYKdeficiency maintained the proliferation status of OLs but did not affect their survival. Thus, AATYK is essential for the differentiation of OLs. | Chunxia Jiang Wanqing Yang Zhihong Fan Peng Teng Ruyi Mei Junlin Yang Aifen Yang Mengsheng Qiu Xiaofeng Zhao | 2018 | Neuroscience Bulletin2018,34,3: | 2 |
