| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Sonodynamic therapy(SDT): a novel strategy for cancer nanotheranostics显示文摘Sonodynamic therapy(SDT) is a promising non-invasive therapeutic modality. Compared to photo-inspired therapy, SDT provides many opportunities and benefits, including deeper tissue penetration, high precision, less side effects, and good patient compliance. Thanks to the facile engineerable nature of nanotechnology, nanoparticles-based sonosensitizers exhibit predominant advantages, such as increased SDT efficacy, binding avidity, and targeting specificity. This review aims to summarize the possible mechanisms of SDT, which can be expected to provide the theoretical basis for SDT development in the future. We also extensively discuss nanoparticle-assisted sonosensitizers to enhance the outcome of SDT. Additionally, we focus on the potential strategy of combinational SDT with other therapeutic modalities and discuss the limitations and challenges of SDT toward clinical applications. | Xueting Pan Hongyu Wang Shunhao Wang Xiao Sun Lingjuan Wang Weiwei Wang Heyun Shen Huiyu Liu | 2018 | Science China(Life Sciences)2018，61，4： | 26 |
| 3 | Promotional effect of Si-doped V_2O_5/TiO_2 for selective catalytic reduction of NOx by NH_3显示文摘TiO2 supports doped with different amounts of Si were prepared by a sol-gel method, and 1 wt% vanadia (V2O5) loaded on Si-doped TiO2 was obtained by an impregnation method. The mole ratio of Si/Ti was 0.2, NOx conversion exceeds 94% at 300℃ and GHSV of 41,324 hr-1 , which is about 20% higher than pure V2O5/TiO2 . The catalysts were characterized by XRD, BET, TEM, FT-IR, NH3-TPD, XPS, H2-TPR, Raman and in situ DRIFTS. The results of FT-IR and XPS indicated that Si was doped into the TiO2 lattice successfully and a solid solution was obtained. V2O5 active component could be dispersed well on the support with the increasing of surface area of the catalyst, which was confirmed by Raman and XRD results. Above all, the numbers of acid sites (especially the Br nsted-acid) and oxidation properties were enhanced for Si-doped V2O5/TiO2 catalysts, which improved the deNOx catalytic activity. | Yanxiao Pan Wei Zhao Qin Zhong Wei Cai Hongyu Li | 2013 | Journal of Environmental Sciences2013，25，8： | 13 |
| 4 | Concurrent intracranial and extracranial artery stenosis and the prognosis of transient ischaemic symptoms or imaging-negative ischaemic stroke显示文摘Background and purpose Transient ischaemic attack(TIA),transient symptoms with infarction(TSI)and diffusion-weighted imaging(DWI)-negative acute ischaemic stroke(AIS)share similar aetiologies but are considered to have a rather benign prognosis.We intended to investigate the association between intracranial atherosclerotic stenosis(ICAS),extracranial atherosclerotic stenosis(ECAS)and the prognosis of patients with TIA,TSI and DWI-negative AIS.Methods Clinical and imaging data of eligible participants were derived from the Chinese Intracranial Atherosclerosis study,according to symptom duration,acute infarction on DWI and discharge diagnosis.Based on the severity and location of arterial atherosclerosis,we categorised the study population into four groups:no or<50% ICAS and no ECAS;≥50% ICAS but no ECAS;no or<50%ICAS with ECAS;and concurrent≥50% ICAS and ECAS.Using multivariable Cox regression models,we analysed the relationship between the severity and distribution of large artery atherosclerosis and the prognosis of TIA,TSI and DWI-negative AIS.Results A total of 806 patients were included,67.3% of whom were male.The median age of the study participants was 63 years.Patients in the concurrent≥50% ICAS and ECAS subgroup had both a significantly higher 1-year recurrence rate(adjusted HR 3.4(95%CI 1.15 to 10.04),p=0.027)and a higher risk of composite vascular events(adjusted HR 3.82(95%CI 1.50 to 9.72),p=0.005).Conclusions Concurrent ICAS and ECAS is associated with a higher possibility of 1-year recurrent stroke or composite vascular events.Large artery evaluation is necessary to assess patients with transient ischaemic symptoms or DWI-negative AIS.Progress in shortening the time interval between symptom onset and large vessel evaluation is needed. | Yue Suo Jing Jing Yuesong Pan Weiqi Chen Hongyu Zhou Hao Li Yuehua Pu Liping Liu Xingquan Zhao Yilong Wang Xia Meng Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，1： | 10 |
| 5 | Effect of Salinity on Hemolymph Osmotic Pressure,Sodium Concentration and Na^+-K^+-ATPase Activity of Gill of Chinese Crab,Eriocheir sinensis显示文摘The effects of salinity on hemolymph osmotic pressure, Na+ concentration and Na+-K+-ATPase activity of gill of Chinese crab Eriocheir sinensis were studied. The results showed that hemolymph osmotic pressure and Na+ concentration increased signifi- cantly (P<0.05), and the Na+-K+-ATPase activity of gills decreased significantly (P<0.05) when salinity increased from 0 to 16. The hemolymph osmotic pressure and Na+ concentration in each treatment group rose remarkably at 0.125 d or 0.25 d, while the Na+-K+-ATPase activity of gill reduced gradually with increased experiment time in 3 d. Then the three parameters remained at a constant level after 0.25 d, 0.125 d and 3 d, respectively, and higher hemolymph osmotic pressure, higher Na+ concentration and lower Na+-K+-ATPase activity of gill occurred at higher salinity. The effect of salinity change on protein concentration of hemolymph was indistinct (P>0.05); However, the protein concentration decreased gradually with the increase of salinity from 0.25 d to 1 d, and then tended to be stable from day 1 to day 15. | LIU Hongyu PAN Luqing LU Fu | 2008 | Journal of Ocean University of China2008，7，1： | 6 |
| 6 | Effect of Salinity on the Biosynthesis of Amines in Litopenaeus vannamei and the Expression of Gill Related Ion Transporter Genes显示文摘This study examined the effect of salinity on the expression of Na+/K+-ATPase(NKA) α-subunit and vacuolar-type H+-ATPase(V-ATPase) β-subunit gene in the gill of Litopenaeus vannamei. Semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR) assay showed that the expression of NKA α-subunit and V-ATPase β-subunit gene was significantly influenced by salinity. It was found that the NKA activity significantly varied with salinity in time and dose dependent manner; whereas the V-ATPase activity did not. The abundance of NKA α-subunit gene transcript increased rapidly when the salinity decreased from 26 b to 21, and slowly when the salinity decreased from 26 to 31 within the first 24 h. When the salinity decreased from 26 to 21, the transcription of NKA α-subunit gene in gill epithelium was higher at 12 h than that at 0 h, which was consistent with the result of immunoblotting assay of NKA α-subunit. In addition, salinity had a significant time- and dose-dependent effect on the concentration of biogenic amines in both hemolymph and gill. As compared to other parameters, the concentration of dopamine(DA) and 5-hydroxytryptamine(5-HT) varied in different patterns when the salinity decreased from 26 to 21 or increased from 26 to 31, suggesting that DA and 5-HT played different regulatory roles in osmotic adaption and modulation of shrimp when salinity varies. | PAN Luqing LIU Hongyu ZHAO Qun | 2014 | Journal of Ocean University of China2014，13，3： | 5 |
| 7 | Fe3C-N-doped carbon modified separator for high performance lithium-sulfur batteries显示文摘A new Fe3C-N-doped reduced graphene oxide(Fe3C-N-rGO)prepared by a facile method is used as a separator for high performance lithium-sulfur(Li-S)batteries.The Fe3C-N-rGO is coated on the surface of commercial polypropylene separator(Celgard 2400)close to the sulfur cathode.The special nanotubes are in-situ catalyzed by Fe3C nanoparticles.They could entrap lithium polysulfides(Li PSs)to restrain the shuttle effect and reduce the loss of active material.The battery with the modified separator and sulfur cathode shows an excellent cycle performance.It has a high rate performance,580.5 mAh/g at the high current rate of 4 C relative to 1075 mAh/g at 0.1 C.It also has an initial discharge capacity of 774.8 m Ah/g measured at 0.5 C and remains 721.8 mAh/g after 100 cycles with a high capacity retention of 93.2%.The outstanding performances are notable in recently reports with modified separator. | Hongyu Pan Zhong Tan Haihui Zhou Lanlan Jiang Zhongyuan Huang Qjaoxia Feng Qiang Zhou Shuai Ma Yafei Kuang | 2019 | Journal of Energy Chemistry2019，28，12： | 5 |
| 8 | High performance of La-doped Y2O3 transparent ceramics显示文摘As an optical material,Y2O3 transparent ceramics are desirable for application as laser host materials.However,it is difficult to sinter and dense of Y2O3 hinders the preparation of high-quality optical ceramics via traditional processes.In this work,we use La2O3 as a sintering aid for fabricating high-transparency Y2O3 ceramics using a vacuum sintering process.It is demonstrated that the in-line optical transmittance of 15.0 at%La-doped Y2O3 at a wavelength of 1100 nm achieves a transmittance of 81.2%.A sintering kinetics analysis reveals that a grain-boundary-diffusion-controlled mechanism dominates the faster densification at high La3+concentrations.It is also shown that both the mechanical and thermal properties of Y2O3 transparent ceramics are significantly improved upon the increase of La2O3 sintering additives.The results indicate that a La-doped Y2O3 transparent ceramic is a promising candidate for a laser host material. | Lei Zhang Jun Yang Hongyu Yu Wei Pan | 2020 | Journal of Advanced Ceramics2020，9，4： | 3 |
| 9 | The effect of Al3+ coordination structure on the propane dehydrogenation activity of Pt/Ga/Al2O3 catalysts显示文摘The effect of the Al2O3 structure on the performance of Pt/Ga/Al2O3 catalysts is investigated for the direct dehydrogenation of propane. The study unveils that the structure of Al3+determines the bulk structure of catalysts, particularly a high content of coordinatively unsaturated Al3+sites(penta-coordinated Al3+,denoted as Al3+penta) could lead to a remarkably improved dehydrogenation activity of the catalyst. The bulk characterization reveals that the sufficient amount of Al3+pentain Al2O3 benefit the dispersion of Pt and Ga2O3 on the Al2O3 support. At the same time, TPR results reveal that the presence of Pt facilitates the reduction of Ga2O3, likely due to the hydrogen spillover between the well dispersed Pt and Ga2O3,which consequently enhances the synergistic function between Pt and Ga2O3 in the dehydrogenation of propane. Recyclability tests demonstrate that the dehydrogenation activity stabilizes after three cycles over the Pt/Ga/Al2O3 catalyst. | Qinqin Yu Tie Yu Hongyu Chen Guangzong Fang Xiulian Pan Xinhe Bao | 2020 | Journal of Energy Chemistry2020，29，2： | 3 |
| 10 | Early Activation of Astrocytes does not Affect Amyloid Plaque Load in an Animal Model of Alzheimer's Disease显示文摘Astrocytes are closely associated with Alzheimer's disease(AD). However, their precise roles in AD pathogenesis remain controversial. One of the reasons behind the different results reported by different groups might be that astrocytes were targeted at different stages of disease progression. In this study, by crossing h APP(human amyloid precursor protein)-J20 mice with a line of GFAP-TK mice, we found that astrocytes were activated specifically at an early stage of AD before the occurrence of amyloid plaques, while microglia were not affected by this crossing. Activation of astrocytes at the age of 3–5 months did not affect the proteolytic processing of hAPP and amyloid plaque loads in the brains of hAPP-J20 mice. Our data suggest that early activation of astrocytes does not affect the deposition of amyloid b in an animal model of AD. | Dongpi Wang Xiaoqin Zhang Mingkai Wang Dongming Zhou Hongyu Pan Qiang Shu Binggui Sun | 2018 | Neuroscience Bulletin2018，34，6： | 3 |
| 11 | Effects of Na^+/K^+ Ratio of Groundwaters on the Gill Ion-Transport Enzyme Activity,Plasma Osmolality and Growth of Cynoglossus semilaevis Juveniles显示文摘The effects of environmental Na+/K+ ratio on the gill ion-transport enzyme activity,plasma osmolality and growth of Cynoglossus semilaevis juveniles were investigated. The results showed that,plasma osmolality was similar among flounder adapted to different Na+/K+ ratios of saline groundwaters (P>0.05),while the growth,gill Na+,K+-ATPase and HCO3--ATPase activities were affected by Na+/K+ ratio significantly (P<0.05). The gill Na+,K+-ATPase activity reached its maximum on day 3,then decreased gradually from day 3 to day 9 and remained constant from day 9 to day 15. The peak values of gill Na+,K+-ATPase activity were detected on day 3 for all Na+/K+ ratios of saline groundwaters,then the enzyme activities descended,and on day 9 the enzyme activi-ties achieved steady state,and the gill HCO3--ATPase activity increased rapidly and achieved steady state after one day. During steady state,the gill Na+,K+-ATPase and HCO3--ATPase activity of Na+/K+ ratios 20 and 40 treatments were significantly higher than those in the control group (Na+/K+ ratio 27.5),while there were no significant differences between the Na+/K+ ratio 30 treatment and the control group; the gill Na+,K+-ATPase activity of Na+/K+ ratio 20 and 40 treatments were significantly higher than that for ratio 30 treatment,but there were no significant differences of gill HCO3--ATPase activity among these treatments. At the end of the 15-day experiment,the weight gain (%) and specific growth rate (SGR) of flounders maintained in seawater were significantly higher than those in groundwaters; significant differences also occurred among the treatments; Na+/K+ ratio 30 treatment had the highest values (33.7% and 1.94 respectively),which were significantly higher than those under Na+/K+ ratios 20 and 40 treatments. There-fore,for the saline groundwater used in this experiment,it is suggested that the Na+/K+ ratio be adjusted to approximately 30,i.e.,as close to that of natural seawater as possible in the culture of flounder. | YANG Huizan PAN Luqing HU Fawen LIU Hongyu | 2008 | Journal of Ocean University of China2008，7，4： | 2 |

| 13 | Integration of preparation of K,Na-embedded activated carbon and reduction of Zn-bearing dusts显示文摘Large amounts of solid wastes and flue gases are generated in iron and steel production process,probably leading to serious environmental pollution without duly handle.An innovative and green process of simultaneous reduction of zinc-bearing dusts and activation of low-rank coal was developed and its mechanism was clarified in this paper.Under the optimal conditions,the reduced zinc-bearing dusts containing low harmful elements(0.02%Zn,0.015%K and 0.03%Na)could be made as high-quality burden for blast furnace while the low-rank coal was transferred into K,Na-embedded activated carbon,which can be used as effective adsorbent for purification of SO_(2) and NO-containing flue gases.The solid wastes were successfully utilized to treat the flue gases through the process.The synergetic activation and reduction mechanism in the process was revealed.The coupling effect between reduction reactions of metal oxides in the dusts and activation reaction of carbon in the coal promoted the simultaneous reduction and activation process.In the meanwhile,part of the potassium and sodium from the zinc-bearing dusts could be adsorbed by the activated carbon and played a catalytic role in the activation process. | Dingzheng Wang Deqing Zhu Jian Pan Zhengqi Guo Congcong Yang Hongyu Tian Yuxiao Xue | 2022 | International Journal of Mining Science and Technology2022，32，3： | 1 |
| 14 | Effect of sex differences on prognosis of intravenous thrombolysis: data from the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China (TIMS- China)显示文摘Background and purpose Previous studies have reported conflicting results as to whether women have poorer functional outcome than men after thrombolytic therapy.This study aims to investigate the relationship between sex differences and the prognosis of intravenous thrombolysis in Chinese patients with acute ischaemic stroke.Methods The patients enrolled in this study were from the Chinese Acute Ischemic Stroke Thrombolysis Monitoring and Registration study.The primary outcome was poor functional outcome,defined as a 3-month modified Rankin score of 3-6.The safe outcome was symptomatic intracranial haemorrhage(SICH)and mortality within 7 days and 90 days.Multiple Cox regression model was used to correct the potential covariates to evaluate the association between sex disparities and prognosis.Furthermore,the interaction of preonset Rankin scores,baseline National Institute of Health Stroke Scale(NIHSS)scores and Trial of Org 10172 in Acute Stroke Treatment(TOAST)types was statistically analysed.results A total of 1440 patients were recruited,including 541 women and 899 men.The baseline information indicated that women were older at the time of onset(66.2±11.2 years vs 61.0±11.3 years,p<0.001),and more likely to have a history of atrial fibrillation(25.3%vs 11.2%,p<0.001),and had a higher NIHSS score on admission(12.3±6.8 vs 11.6±6.7,p=0.04).According to the prognosis analysis of unsatisfactory functional recovery,there was no significant difference between women and men(45.9%vs 37.1%;adjusted OR 1.01,95%CI 0.75 to 1.37).As for the safe outcome,the proportion of SICH and mortality in women is relatively high but did not reach statistical significance.There was no significant interaction with sex,age,preonset Rankin score,NIHSS score,TOAST classification and the prognosis of intravenous thrombolysis.Conclusions For Chinese patients with ischaemic stroke,although women are older and more severe at the time of onset,the prognosis after intravenous thrombolysis is not significantly different from men. | Hongyu Zhou Weiqi Chen Yuesong Pan Yue Suo Xia Meng Hao Li Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，1： | 1 |

| 19 | A comparative study on the performances of synthetic diamond made by belt press & cubic press显示文摘There are mainly two kinds of equipment to produce synthetic diamond,namely belt press & cubic press.It has been customary in the industry to regard synthetic diamond produced by cubic press is inferior to that made by belt press.With the on-going improvement in technology,know-how & accumulated experiences, perhaps it’ s time for us to review the qualities & performances of synthetic diamond made by the cubic press more objectively.Studies were carried out on the performances of the two kinds of diamond by choosing from top brands & top qualities,with coarser mesh sizes 20/30 & 30/40.Comparisons were made on parameters, such as TI,TTI,PPC,bulk density,compact,roughness and arealight.And the diamonds chosen were used to produce the relevant diamond core drill bits and saw blades,their respective cutting performances such as cutting efficiency,segments consumption were measured and reported in this paper.The report demonstrates that producing the high quality diamond does not depend on the type of presses(Belt or Cubic) but rather on the know-how,technology and what it is made. | Jia Pan~1,Lu Canhua~1,Ye Hongyu~2,Li Zhihong~3 (1.Nanyang Zhongnan Diamond Co.,Ltd.Nanyang,China) (2.Wuhan Wanbang Laser Diamond Tools Co.,Wuhan,China) (3.Industrial Diamond Association of China,Zhengzhou 450013,China ) | 2008 | 金刚石与磨料磨具工程2008，28，S1： | 1 |
| 20 | Effect mechanism of aluminum occurrence and content on the induration characteristics of iron ore pellets显示文摘With the intensified depletion of high-grade iron ores,the increased aluminum content in iron ore concentrates has become unavoidable,which is detrimental to the pelletization process.Therefore,the effect mechanism of aluminum on pellet quality must be identified.In this study,the influence of aluminum occurrence and content on the induration of hematite(H)and magnetite(M)pellets was investigated through the addition of corresponding Al-containing additives,including alumina,alumogoethite,gibbsite,and kaolinite.Systematic mineralogical analysis,combined with the thermodynamic properties of different aluminum occurrences and the quantitative characterization of consolidation behaviors,were conducted to determine the related mechanism.The results showed that the alumina from various aluminum occurrences adversely affected the induration characteristics of pellets,especially at an aluminum content of more than 2.0wt%.The thermal decomposition of gibbsite and kaolinite tends to generate internal stress and fine cracks,which hinder the respective microcrystalline bonding and recrystallization between Fe2O3particles.The adverse effect on the induration characteristics of fired pellets with different aluminum occurrences can be relieved to varying degrees through the formation of liquid phase bonds between the hematite particles.Kaolinite is more beneficial to the induration process than the other three aluminum occurrences because of the formation of more liquid phase,which improves pellet consolidation.The research results can further provide insights into the effect of aluminum occurrence and content in iron ore concentrates on downstream processing and serve as a guide for the utilization of high-alumina iron ore concentrates in pelletization. | Hongyu Tian Deqing Zhu Jian Pan Congcong Yang Weiqun Huang Mansheng Chu | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，12： | 0 |
