| 1 | Trend of declining stroke mortality in China:reasons and analysis显示文摘Introduction There is a downward trend of stroke-related mortality in the USA.By reviewing all published articles on stroke mortality in China,we analysed its trend and possible factors that have influenced the trend.Methods Both English and Chinese literatures were searched on the mortality of stroke or cerebrovascular diseases in China.Potential papers related to this topic were identified from PubMed,Medline,Embase,Cochrane Library,Wanfang Database,SINOMED and China National Knowledge Infrastructure databases.Results Comparing the results from the most recent population-based epidemiological survey and databank from the national Center for Disease Control and Prevention,the age-adjusted stroke mortality rate has shown a downward trend among both urban and rural population in the past 30 years in China.Comparing with 30 years ago,the rate of stroke mortality has decreased by more than 31%in urban/suburban population and 11%in rural population.In men,the age-adjusted stroke mortality rate decreased by 18.9%and in women by 24.9%between 1994 and 2013.Factors that may have contributed to the trend of decreased stroke mortality rate include(1)improved healthcare coverage and healthcare environment;(2)improved treatment options and medical technology;(3)support by government to educate the public on stroke and stroke prevention;and(4)improved public knowledge on stroke.Conclusions The age-adjusted stroke mortality rate in China has shown a downward trend among both urban and rural population in the past 30 years.The major influencing factors that helped in reducing stroke mortality in China included improved healthcare coverage,healthcare environment,the updated treatment options and modern medical technology. | Wenzhi Wang David Wang Hongmei Liu Haixin Sun Bin Jiang Xiaojuan Ru Dongling Sun Zhenghong Chen Yongjun Wang | 2017 | Stroke & Vascular Neurology2017，2，3： | 52 |
| 2 | Earth surface processes and their effects on human behavior in monsoonal China during the Pleistocene-Holocene epochs显示文摘There is a wide diversity of landforms in China.The topography of three major terraces,decreasing in height stepwise from west to east,was formed by the early Miocene.With the commencement of the Great Northern Hemisphere Glaciations(GHGs)and the glacial-interglacial cycles in the Pleistocene,thick loess deposits accumulated in north China,and fluvial terraces were formed and lakes expanded and contracted in eastern and central China.The earliest evidence of hominins in China is dated to ~1.7 Ma;they occupied the monsoon-dominated region for a long interval,until the late Pleistocene,~50 ka.In this study,we investigated a large area rich in the relics and artifacts of early man.The results indicate that the early humans occupied riverine areas,especially medium-sized fluvial basins,and lake shores.Even in the relatively recent geological past,the occupation and abandonment of settlements were directly forced by the shifting of sand dune fields in the desert-loess transitional zone,which in turn was closely associated with variations in the monsoon climate and vegetation patterns.Our observations indicate that landforms were one of the main determinants of early human behavior,in that loess tableland,large alluvial plains,desert-Gobi areas,and the Tibetan Plateau,were not suitable environments for early human settlement.We infer that the early humans in China adapted their behavior to specific landforms and landform processes.The monsoon climate,which shapes the large-scale step-like pattern of fluvial landforms,promotes vegetation coverage and dominates soil formation,provides a crucial context for early human adaptation.The adaptation of early humans to earth surface processes in East Asia is investigated for the first time in this study.Future investigations will provide further information that will increase our understanding of the linkage between early human behavior and landform processes in East Asia. | LU Huayu ZHUO Haixin ZHANG Wenchao WANG Shejiang ZHANG Hongyan SUN Xuefeng JIA Xin XU Zhiwei WANG Xianyan | 2017 | Journal of Geographical Sciences2017，27，11： | 12 |
| 3 | Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders:executive summary and 2019 update of the management of high-risk population显示文摘Aim Cerebrovascular disease is the leading cause of death and disability in China,causing a huge burden among patients and their families.Hence,stroke prevention is critical,especially in the high-risk population.Here,we present the evidence-based guideline suitable for the Chinese population.Methods Literature search of PubMed and Cochrane library(from January 1964 to June 2019)was done.After thorough discussion among the writing group members,recommendations were listed and summarised.This guideline was reviewed and discussed by the fellow writing committees of the Chinese Stroke Association’s Stroke.Results This evidence-based guideline was written in three parts:controlling the risk factors of stroke,utilisation of antiplatelet agents and assessing the risks of first-ever stroke.All recommendations were listed along with the recommending classes and levels of evidence.Conclusions This guideline provides recommendations for primary prevention of cerebrovascular disease among high-risk population in China.Controlling related risk factors,appropriately using antiplatelet agents,assessing the risk of developing first-ever stroke should help reduce the rate of cerebrovascular disease in China. | Yilong Wang Shangrong Han Haiqiang Qin Huaguang Zheng Bin Jiang Yong Cao Yuan Gao Ling Guan Qian Jia Yong Jiang Yuming Jiao Shuya Li Yapeng Li Zixiao Li Wei Liu Xiaojuan Ru Dongling Sun Haixin Sun Penglian Wang Tingting Wang Lixia Zong Lei Guo Xuewei Xie Yuming Xu Yuyuan Xu Xiaomeng Yang Yingying Yang Mengyuan Zhou Wenzhi Wang Chinese Stroke Association Stroke Council Guideline Writing Committee | 2020 | Stroke & Vascular Neurology2020，5，3： | 11 |
| 4 | Carrier frequency offset and impulse noise estimation for underwater acoustic orthogonal frequency division multiplexing显示文摘The carrier frequency offset(CFO)and impulse noise always affect the performance of underwater acoustic communication_systems.The CFO and impulse noise could be estimated by using the null subcarriers to cancel the effects of the two types of interference.The null subcarriers estimation methods include optimal separate estimation and joint estimation.The separate estimation firstly estimates the CFO value and then estimates the impulse noise value.However,the CFO and impulse noise always affect each other when either of them is estimated separately.The performance could be improved by using the joint estimation.The results of simulations and experiments have showed that these two optimization methods have good performance and the joint estimation has better performance than the separate estimation method.There is 3 dB performance gain at the BER value of 10^(-2)when using the joint estimation method.Thus these methods could improve the system robustness by using the CFO compensation and impulse noise suppression. | SUN Haixin XU Xiaoka MA Li KUAI Xiaoyan CHENG En CHEN En | 2014 | Chinese Journal of Acoustics2014，33，3： | 8 |
| 5 | Iterative Block DFE for Underwater Acoustic Single Carrier System显示文摘In order to gain a better performance and reduce the computational complexity of the filter design in the underwater acoustic single carrier system, a new Iterative Block DFE (IBDFE) is proposed, which operates iteratively on blocks of the received signal, and fully implements its filtering operations by Discrete Fourier Transforms (DFTs). Two design methods are considered for IBDFE: one is HD-IBDFE, and the other is SD-IBDFE. In this paper, the first one is adopted. In this scheme, hard detected data are used as input of the feedback, and filters are designed according to the correlation between detected and transmitted data. In the simulations and experiments, the method of the HD-IBDFE is introduced, and for comparison, the performance of H-DFE is shown, as well as that of ZF, MMSE and Matched-Filter-Bound (MFB). From the results of the simulations on a Rayleigh fading channel, it is easily found that on average, the HD-IBDFE outperforms H-DFE. When the number of iteration is 4, HD-IBDFE outperforms ZF, MMSE and H-DFE by about 11dB, 5dB and 0.7dB respectively at BER=10-4. As for MFB, the HD-IBDFE still has a degradation of 1.6 dB. In addition, the experimental results in both experiment pool and shallow water also verify the achievement. The simulation and experiment results indicate that the IBDFE outperforms other equalization schemes. What's more, it exhibits a reduction of the computational complexity. | Sun Haixin Guo Yuhui Kuai Xiaoyan Cheng En | 2012 | China Communications2012，9，7： | 4 |
| 6 | Genome-wide analysis identified 17 new loci influencing intraocular pressure in Chinese population显示文摘Intraocular pressure(IOP) is a major risk factor for glaucoma. Genetic determinants of intraocular pressure can provide critical insights into the genetic architecture of glaucoma and, as a result, open new avenues for therapeutic intervention. We performed a genome-wide association study and replication analysis of 8,552 Chinese participants. In the genome-wide association study, we identified 51 loci that surpassed the significance of P<9×10^(-7), and we formally replicated these loci. A combined discovery and replication meta-analysis identified 21 genome-wide loci that surpassed the genome-wide significance of P<5×10^(-8), including 4 previously reported loci: rs145063132(7 p21.2, ETV1/DGKB), rs548030386(7 q31.2, ST7 near CAV1/CAV2), rs7047871(9 p24.2, GLIS3), and rs2472494(9 q31.1, ABCA1/SLC44 A1). Of the 17 newly identified loci, five were reported to have ocular related phenotypes: PTCH2(rs7525308 in 1 p34.1), LRIF1/DRAM2(rs1282146 in 1 p13.3), COLEC11(rs201143466 in 2 p25.3),SPTBN1(rs4514918 in 2 p16.2), and CRK(rs11078446 in 17 p13.3). The genetic loci identified in this study not only increase our understanding of the genes involved in intraocular pressure but also provide important genetic markers to improve future genetic screening and drug discovery for intraocular pressure disorders. | Lulin Huang Yuhong Chen Ying Lin Pancy O.S.Tam Yilian Cheng Yi Shi Bo Gong Fang Lu Jialiang Yang Haixin Wang Yi Yin Yong Cao Dan Jiang Ling Zhong Bai Xue Jing Wang Fang Hao Dean-Yao Lee Chi-Pui Pang Xinghuai Sun Zhenglin Yang | 2019 | Science China(Life Sciences)2019，62，2： | 4 |
| 7 | Tranexamic acid for acute intracerebral haemorrhage growth based on imaging assessment (TRAIGE): a multicentre, randomised, placebo- controlled trial显示文摘Background Studies show tranexamic acid can reduce the risk of death and early neurological deterioration after intracranial haemorrhage.We aimed to assess whether tranexamic acid reduces haematoma expansion and improves outcome in intracerebral haemorrhage patients susceptible to haemorrhage expansion.Methods We did a prospective,double-blind,randomised,placebo-controlled trial at 10 stroke centres in China.Acute supratentorial intracerebral haemorrhage patients were eligible if they had indication of haemorrhage expansion on admission imaging(eg,spot sign,black hole sign or blend sign),and were treatable within 8 hours of symptom onset.Patients were randomly assigned(1:1)to receive either tranexamic acid or a matching placebo.The primary outcome was intracerebral haematoma growth(>33% relative or>6 mL absolute)at 24 hours.Clinical outcomes were assessed at 90 days.Results Of the 171 included patients,124(72.5%)were male,and the mean age was 55.9±11.6 years.89 patients received tranexamic acid and 82 received placebo.The primary outcome did not differ significantly between the groups:36(40.4%)patients in the tranexamic acid group and 34(41.5%)patients in the placebo group had intracranial haemorrhage growth(OR 0.96,95% CI 0.52 to 1.77,p=0.89).The proportion of death was lower in the tranexamic acid treatment group than placebo group(8.1%vs 10.0%),but there were no significant differences in secondary outcomes including absolute intracranial haemorrhage growth,death and dependency.Conclusions Among patients susceptible to haemorrhage expansion treated within 8 hours of stroke onset,tranexamic acid did not significantly prevent intracerebral haemorrhage growth.Larger studies are needed to assess safety and efficacy of tranexamic acid in intracerebral haemorrhage patients. | Jingyi Liu Ximing Nie Hongqiu Gu Qi Zhou Haixin Sun Ying Tan Dacheng Liu Lina Zheng Jiahui Zhao Yan Wang Yibin Cao Haomeng Zhu Yunpeng Zhang Lijin Yi Yuehua Pu Miao Wen Zhonghua Yang Shengjun Sun Wenzhi Wang Xingquan Zhao Liping Liu Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，2： | 3 |

| 13 | Electrospun gelatin/chitosan nanofibers containing curcumin for multifunctional food packaging显示文摘Recently,food grade nanofiber-based materials have received growing attentions in food packaging.In this work,novel active and intelligent packaging nanofibers based on gelatin/chitosan with curcumin(GA/CS/CUR)were developed via electrospinning technique.Effects of the incorporation of CUR content(0.1%-0.3%,m/m)on the microstructure and functional properties of the electrospun nanofibers were investigated.Morphological studies using scanning electron microscopy indicated that loading CUR can affect the average diameter of nanofiber mats,which remained around 160-180 nm.The addition of an appropriate level CUR(0.2%,m/m)led to a stronger intermolecular interaction,and thus enhanced the thermal stability and tensile strength of the obtained nanofibers.Meanwhile,the incorporation of CUR significantly improved antioxidant activity and the antimicrobial activity of GA/CS/CUR nanofibers.Moreover,the sensitivity of nanofibers to ammonia results indicated that GA/CS nanofibers containing 0.2%CUR(GA/CS/CURⅡ)presented high sensitivity of colorimetric behavior to ammonia(within 3 min).These results suggest GA/CS/CURⅡnanofibers has great potential as a multifunctional packaging to protect and monitor the freshness of proteinrich animal foods,such as meat and seafood. | Mengxia Duan Jishuai Sun Yequn Huang Haixin Jiang Yaqin Hu Jie Pang Chunhua Wu | 2023 | Food Science and Human Wellness2023，12，2： | 1 |

| 15 | NONLINEAR DIFFUSION FOR ORIENTATION ESTIMATION显示文摘This letter presents an image orientation estimation method which is based on a combination of two techniques: quadrature filtering and nonlinear diffusion. The quadrature filters are used to get the orienta-tion tensors for edges, then the orientation tensors are smoothed through nonlinear diffusion. Experimental re-sults and analysis show the robustness of the proposed method. | Shao Xiaofang Sun Jixiang Chen Haixin | 2006 | Journal of Electronics(China)2006，23，4： | 1 |
| 16 | Method for the extraction of circulating nucleic acids based on MOF reveals cell-free RNA signatures in liver cancer显示文摘Cell-free RNA(cf RNA) allows assessment of health, status, and phenotype of a variety of human organs and is a potential biomarker to non-invasively diagnose numerous diseases. Nevertheless, there is a lack of highly efficient and bias-free cf RNA isolation technologies due to the low abundance and instability of cf RNA.Here, we developed a reproducible and high-efficiency isolation technology for different types of cell-free nucleic acids(containing cf RNA and viral RNA) in serum/plasma based on the inclusion of nucleic acids by metal-organic framework(MOF) materials, which greatly improved the isolation efficiency and was able to preserve RNA integrity compared with the most widely used research kit method. Importantly, the quality of cf RNA extracted by the MOF method is about 10-fold that of the kit method, and the MOF method isolates more than three times as many different RNA types as the kit method. The whole transcriptome mapping characteristics of cf RNA in serum from patients with liver cancer was described and a cf RNA signature with six cf RNAs was identified to diagnose liver cancer with high diagnostic efficiency(area under curve = 0.905 in the independent validation cohort) using this MOF method. Thus, this new MOF isolation technique will advance the field of liquid biopsy, with the potential to diagnose liver cancer. | Yuqing Sun Haixin Yu Shaoqing Han Ruoxi Ran Ying Yang Yongling Tang Yuhao Wang Wenhao Zhang Heng Tang Boqiao Fu Boshi Fu Xiaocheng Weng Song-Mei Liu Hexiang Deng Shuang Peng Xiang Zhou | 2024 | National Science Review2024，11，1： | 0 |
| 17 | Tolerance and acceptance of hepatic venous pressure gradient measurement in cirrhosis(CHESS1904):An international multicenter study显示文摘Aim:To determine the tolerance and acceptance of hepatic venous pressure gradient(HVPG)measurements in patients with liver cirrhosis.Methods:This prospective international multicenter study included 271 patients with cirrhosis who were scheduled to undergo HVPG measurement between October 2019 and June 2020.Data related to the tolerance and acceptance of HVPG measurements were collected using descriptive questionnaires.Results:HVPG measurements were technically successful in all 271 patients,with 141(52.0%)undergoing HVPG measurement alone.The complication rate was 0.4%.Postoperative pain was significantly lower than preoperative expected pain(p<0.001)and intraoperative pain(p<0.001),and intraoperative pain was also significantly lower than preoperative expected pain(p=0.036).No,mild,moderate,severe,and intolerable discomfort scores were reported by 36.9%,44.6%,11.1%,6.3%,and 0.4%of these patients,respectively,during HVPG measurement and by 54.6%32.5%,11.4%,1.5%,and 0%,respectively,after HVPG measurement.Of these patients,39.5%had little understanding and 10%had no understanding of the value of HVPG measurement,with 35.1%and 4.1%regarding HVPG measurements as being of little or no help,respectively.Most patients reported that they would definitely(15.5%),probably(46.9%),or possibly(29.9%)choose to undergo additional HVPG measurements again,and 62.7%regarded the cost of the procedure as acceptable.Conclusion:HVPG measurement was safe and well‐tolerated in patients with cirrhosis,but patient education and communication are warranted to improve the acceptance of this procedure. | Jun‐Hui Sun He Zhao Haijun Zhang Lei Li NecatiÖrmeci Zi‐Niu Yu Xun Li Shuangxi Li Xujun Yang Huaping Wei Xiaoliang Zhu Zhengcong Zhang Yajin Wang Zhongwei Zhao Jianting Mao Qiaohong Wu Xiaole Sun Huiling Xiang Kefeng Jia Chao Yang Wei Wu Xiuqing Lin Haixin Yao Changzeng Zuo Jitao Wang Bo Zhang Chunqing Zhang Xiaoling Wu Guangchuan Wang Shengjuan Yao Ruihang Wang Li Zhou Hui Huan Qingli Tu Xue Pu Feng Zhang Qin Yin Linpeng Zhang Ying Guo Jian Wang Kohei Kotani Sawako Uchida‐Kobayashi Norifumi Kawada He Zhu Li Li Wei Wang Guo Zhang Lei Yu Xudong Cui Qingliang Zhu Hailong Zhang Xiaoli Hu Rafael OXimenes Adriano Gonçalves de Araújo Giulliano Gardenghi Yubao Zheng Zebin Wu Mingsheng Huang Xiaoyong Chen Jun Wu Feng Xie Yang Bo Shengjuan Hu Linke Ma Xiao Li Xiaolong Qi | 2022 | Portal Hypertension & Cirrhosis2022，1，1： | 0 |

| 19 | Solubility of iron(Ⅲ) and nickel(Ⅱ) acetylacetonates in supercritical carbon dioxide显示文摘As a common precursor for supercritical CO_(2)(scCO_(2))deposition techniques,solubility data of organometallic complexes in scCO_(2)is crucial for the preparation of nanocomposites.Recently,metal acetylacetonates have shown great potential for the preparation of single-atom catalytic materials.In this study,the solubilities of iron(Ⅲ)acetylacetonate(Fe(acac)3)and nickel(Ⅱ)acetylacetonate(Ni(acac)2)were measured at the temperature from 313.15 to 333.15 K and in the pressure range of 9.5–25.2 MPa to accumulate new solubility data.Solubility was measured using a static weight loss method.The semi-empirical models proposed by Chrastil and Sung et al.were used to correlate the solubility data of Fe(acac)3 and Ni(acac)2.The equations obtained can be used to predict the solubility of the same system in the experimental range. | Haixin Sun Jianlei Qi Jianfei Sun Lin Li Kunpeng Yu Jintao Wu Jianzhong Yin | 2024 | Chinese Journal of Chemical Engineering2024，65，1： | 0 |
| 20 | Subinhibitory Levels of Fluoroquinolones Result in Enrichment of the Membrane Proteome of Staphylococcus aureus显示文摘Staphylococcus aureus is a common marine foodborne pathogen.In this study,antibiotics ciprofloxacin and enrofloxacin were used to induce drug-resistance in S.aureus.The differentially expressed proteins(DEPs)were analyzed and compared with those in the bacteria cultured without antibiotics.The primary proteomic alterations were in the levels of cell membrane components and proteins related to lysine and folic acid biosynthesis,which were all significantly up-regulated.The minimal inhibitory concentrations(MIC)for both test drugs were elevated to 10μg m L^(-1)following serial passaging.These results indicated that,for both ciprofloxacin and enrofloxacin,drug-resistance were developed even in the subinhibitory levels and the primary response was a major alteration in the cell membrane proteome.These changes were similar to those observed in S.aureus cultured with super-MIC levels of these antibiotics.The current study provides a theoretical basis for in-depth study of the related changes of marine foodborne pathogens in subinhibitory concentrations that are commonly found in situ. | XU Xiaoxiao LIN Hong GUO Jiamin LIU Pei SUN Haixin | 2023 | Journal of Ocean University of China2023，22，5： | 0 |
