| 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 | The Chinese Stroke Association scientific statement:intravenous thrombolysis in acute ischaemic stroke显示文摘The most effective medical treatment for acute ischaemic stroke(AIS)is to offer intravenous thrombolysis during the ultra-early period of time after the onset.Even based on the Consensus of Chinese Experts on Intravenous Thrombolysis for AIS in 2012 and 2014 Chinese Guidelines on the Diagnosis and Treatment of AIS,the rate of thrombolysis for AIS in China remained around 2.4%,and the rate of intravenous tissue plasminogen activator usage was only about 1.6%in real world.The indication of thrombolysis for AIS has been expanded,and contraindications have been reduced with recently published studies.In order to facilitate the standardisation of treating AIS,improve the rate of thrombolysis and benefit patients who had a stroke,Chinese Stroke Association has organised and developed this scientific statement. | Qiang Dong Yi Dong Liping Liu Anding Xu Yusheng Zhang Huaguang Zheng Yongjun Wang 无 | 2017 | Stroke & Vascular Neurology2017，2，3： | 56 |
| 3 | The age of the base of the Paleoproterozoic Hutuo Group in the Wutai Mountains area, North China Craton: SHRIMP zircon U-Pb dating of basaltic andesite显示文摘Basalt and basaltic andesite metamorphosed at greenschist facies occurs with conglomerate layers at the bottom of the Paleoproterozoic Hutuo Group in the Wutai Mountains area, North China Craton. Detailed geological surveying confirms that these volcanic rocks are conformable within the neighboring sedimentary rocks. The SHRIMP results on basaltic andesite are divided into two groups. In one group the 207Pb/206Pb ages are from 2433 to 2558 Ma, which is consistent with the basement crustal age in Fuping and Wutai areas. In the other group, 13 grains yielded a weighted mean 207Pb/206Pb age of 2140±14 Ma. The latter is interpreted as the eruption age of the basaltic andesite, and gives the age of the base of the Hutuo Group. This result further suggests that the Hutuo Group formed in the middle Paleoproterozoic, not the early Palaeoproterozoic or late Archaean, as thought before, and is related to a 2.2-2.1 Ga rifting event in the Central North China Craton. | DU LiLin YANG ChongHui GUO JingHui WANG Wei REN LiuDong WAN YuSheng GENG YuanSheng | 2010 | Chinese Science Bulletin2010，55，17： | 43 |

| 5 | Detrital zircon age model of Ordovician Wenquan quartzite south of Lungmuco-Shuanghu Suture in the Qiangtang area, Tibet: Constraint on tectonic affinity and source regions显示文摘Early to Middle Ordovician strata, including Wenquan quartzite, occur widely in the Himalaya, Lhasa, and south Qiangtang blocks. The Wenquan quartzite occurs on the south side of the Lungmuco-Shuanghu Suture in the Qiangtang area, Tibet. A total of 145 analyses on detrital zircons from the quartzite show five age ranges of 520-700, ca. 800, 900-1100, 1800-1900, and 2400-2500 Ma, with particularly distinct age peaks of 625 and 950 Ma. The reliable youngest detrital zircon age is 525 Ma, and the oldest, 3180 Ma. Detrital zircons show large variations in Hf isotope composition, with depleted mantle model ages t DM (Hf) ranging from 750 to 3786 Ma. Based on data obtained in this study and by others, the main conclusions are as follows: 1) Low-grade metamorphic sedimentary rocks are distributed extensively in the south of the Lungmuco-Shuanghu Suture and are Phanerozoic in age; 2) Pan-African and Grenville-Jinning tectono-thermal events were well developed in the source region of the Wenquan quartzite; 3) the source region shows crustal addition and recycling of different periods; 4) Wenquan quartzite was derived from the Gondwana metamorphic basement, suggesting that the Qiangtang block is a Gondwanan fragment. | DONG ChunYan LI Cai WAN YuSheng WANG Wei WU YanWang XIE HangQiang LIU DunYi | 2011 | Science China Earth Sciences2011，54，7： | 39 |

| 7 | A novel m6A reader Prrc2a controls oligodendroglial specification and myelination显示文摘While N6-methyladenosine (m6A), the most abundant internal modification in eukaryotic mRNA, is linked to cell differentiation and tissue development, the biological significance of m6A modification in mammalian glial development remains unknown. Here, we identify a novel m6A reader, Prrc2a (Proline rich coiled-coil 2A), which controls oligodendrocyte specification and myelination. Nestin-Cre-mediated knockout of Prrc2a induces significant hypomyelination, decreased lifespan, as well as locomotive and cognitive defects in a mouse model. Further analyses reveal that Prrc2a is involved in oligodendrocyte progenitor cells (OPCs) proliferation and oligodendrocyte fate determination. Accordingly, oligodendroglial-lineage specific deletion of Prrc2a causes a similar phenotype of Nestin-Cre-mediated deletion. Combining transcriptome-wide RNA-seq, m6A-RIP-seq and Prrc2a RIP-seq analysis, we find that Olig2 is a critical downstream target gene of Prrc2a in oligodendrocyte development. Furthermore, Prrc2a stabilizes Olig2 mRNA through binding to a consensus GGACU motif in the Olig2 CDS (coding sequence) in an m6A-dependent manner. Interestingly, we also find that the m6A demethylase, Fto, erases the m6A modification of Olig2 mRNA and promotes its degradation. Together, our results indicate that Prrc2a plays an important role in oligodendrocyte specification through functioning as a novel m6A reader. These findings suggest a new avenue for the development of therapeutic strategies for hypomyelination-related neurological diseases. | Rong Wu Ang Li Baofa Sun Jian-Guang Sun Jinhua Zhang Ting Zhang Yusheng Chen Yujie Xiao Yuhao Gao Qingyang Zhang Jun Ma Xin Yang Yajin Liao Wei-Yi Lai Xiaolong Qi Shukun Wang Yousheng Shu Hai-Lin Wang Fengchao Wang Yun-Gui Yang Zengqiang Yuan | 2019 | Cell Research2019，29，1： | 32 |
| 8 | U-Th-Pb behavior of zircons under high-grade metamorphic conditions:A case study of zircon dating of meta-diorite near Qixia,eastern Shandong显示文摘This paper carried out a study on U—Th—Pb behavior of zircons in a'dry'rock system during high-grade metamorphism in the Archean basement of eastern Shandong.The studied sample has a mineral assemblage of plagioclase + K-feldspar + clinopyroxene + biotite + quartz and its protolith is considered to be diorite.The zircons are stubby,equant or irregular in shape and show fir-leaf, sectorial,banded or oscillatory zoning.They contain inclusions,including mineral assemblages of clinopyroxene + orthopyroxene + hornblende + quartz and plagioclase + K-feldspar + biotite + quartz. Fifty SHRIMP analyses were performed on 34 zircon grains,which commonly yielded high Th/U ratios (mostly>0.5).Most analyses are distributed along concordia from 2.54 to 2.25 Ga,with the youngest age being~1.95 Ga.Compositions and ages show large variations even in a same zircon grain.Combined with early studies,conclusions can be drawn as follows:1) the diorite underwent two episodes of high-grade metamorphism.at the end of the Neoarchean and the Paleoproterozoic(~2.50 Ga and~1.95 Ga or slightly later):2) high-grade metamorphism in a'dry'rock system may partially reset the U—Th—Pb system of zircons and.in this case,the ages between the oldest and youngest | Yusheng Wan Dunyi Liu Chunyan Dong Shoujie Liu Shijin Wang | 2011 | Geoscience Frontiers2011，2，2： | 27 |
| 9 | Explicit diagnosis of the local ozone production rate and the ozone-NOx-VOC sensitivities显示文摘In the troposphere, ozone is a harmful gas compound to both human health and vegetation. Ozone is produced from the reaction of NO_x(@NO + NO_2) and VOCs(volatile organic compounds) with light. Due to the highly nonlinear relationships between ozone and its precursors, proper ozone mitigation relies on the knowledge of chemical mechanisms. In this study, an observation-based method is used to simulate ozone formation and elucidate its controlling factors for a rural site on the North China Plain. The instantaneous ozone production rate is calculated utilizing a box model using the dataset obtained from the Wangdu campaign. First, the model was operated in a time-dependent mode to calculate the ozone production rate at each time stamp. The calculated ozone formation rate showed a diurnal average maximum value of 17 ppbv/h(1-h diurnal averaged). The contribution of individual peroxy radicals to ozone production was analyzed. In addition, the functional dependence of calculated P(O_3) reveals that ozone production was in a NO_x-limited regime during the campaign. Furthermore, the missing peroxy radical source will further extend NO_x-limited conditions to earlier in the day, making NO_xlimitation dominate more of a day than the current chemical model predicts. Finally, a multiple scenarios mode,also known as EKMA(empirical kinetic modeling approach), was used to simulate the response of P(O_3) to the imaginary change in precursor concentrations. We found that ozone production was in the NO_x-limited region. However, the use of NO_2 measured by the molybdenum converter and/or the absence of a peroxy radical source in the current chemical model could over-emphasize the VOC-limited effect on ozone production. | Zhaofeng Tan Keding Lu Huabin Dong Min Hu Xin Li Yuhan Liu Sihua Lu Min Shao Rong Su Haichao Wang Yusheng Wu Andreas Wahner Yuanhang Zhang | 2018 | Science Bulletin2018，63，16： | 25 |
| 10 | Shear Alteration, Mass Transfer and Gold Mineralization: An Example from Jiaodong Ore Deposit Concentrating Area, Shandong, China显示文摘Taking the gold ore deposit concentrating area of Jiaodong area in Shandong, China for an example, based on geological analysis, and applying Gresens’ equation, Grant’s isocon diagram and O’hara microelement calculation method, a thorough study on shear alteration, mass transfer and gold mineralization was carried out. The authors also made mathematic simulation and geochemical analysis. The work reveals temporal spatial changing regularities of temperature field and velocity field of fluids, and also reveals fluid transport chemical reaction coupling metallogenic dynamics of the Jiaojia gold ore concentrating area. During shear alteration process of the Jiaodong gold ore concentrating area, all kinds of components transferred with different amounts, fluid rock ratio was rather high and volume strain was of dilation type. Fast flow of ore forming fluid favors the occurrence of mixed fluid. Shear fractured zones are places where there was strong transportation reaction coupling mineralization. Ore bodies were located in dilation space of shear structure where there was the greatest fluid flux. After the emplacement of the rock body, a convex heat field was formed around the rock body. It is one of the main metallogenic forces. The major reason for mineralization is the mobilization, migration and enrichment of ore forming elements induced by shear compressive extensional tectonism. Inclusion gold dominant low grade ores were formed in the early ore forming stage, while high grade ores, which contained fissure gold and polymetallic veinlets, were formed in late ore forming stage. | Deng Jun Zhai Yusheng Wang Jianping Faculty of Earth Sciences and Mineral Resources, China University of Geosciences, Beijing 100083, China Yang Liqiang Institute of Geophysics, Chinese Academy of Sciences, Beijing 100101, China Fang Yun Faculty of | 2000 | Journal of Earth Science2000，19，3： | 18 |
| 11 | U-Pb dating of zircon from the Central Zone of the East Kunlun Orogen and its implications for tectonic evolution显示文摘LA-ICP-MS and SHRIMP U-Pb dating of zircons from orthogneisses and amphibolite from the Central Zone of the Kunlun Orogen is reported in this paper. One orthogneiss sample has metamorphic zircons yielding weighted average 206Pb/238U age of 517.0 +5.0/-6.0 Ma, and the other orthogneiss sample con- tains zircons with inherited magmatic cores giving three population 207Pb/206Pb ages of 955 Ma, 895 Ma and 657 Ma for the magmatic protolith, and metamorphic recrystallized rims with peak 206Pb/238U ages of 559 +12/?17 Ma and 516 ± 13 Ma. The amphibolite yielded three populations of weighted average 206Pb/238U age of 482.0 +10/?8.0 Ma, 516.2 ± 5.8 Ma and 549 ± 10 Ma for the metamorphic zircons. These dating results recorded the tectonothermal events that occurred in the early Paleozoic and the Pre- cambrian time. The records of the Cambrian magmatic-metamorphic event in the Qinling Orogen, the Altyn Tagh belt, north margin of the Qaidam Block and the Kunlun Orogen suggest that continental assembly probably occurred in the early evolutionary history of the Proto-Tethys. | CHEN NengSong SUN Min WANG QinYan ZHANG KeXin WAN YuSheng CHEN HaiHong | 2008 | Science China Earth Sciences2008，51，7： | 13 |
| 12 | Elimination of senescent cells byβ-galactosidase-targeted prodrug attenuates inflammation and restores physical function in aged mice显示文摘Cellular senescence,a persistent state of cell cycle arrest,accumulates in aged organisms,contributes to tissue dysfunction,and drives age-related phenotypes.The clearance of senescent cells is expected to decrease chronic,low-grade inflammation and improve tissue repair capacity,thus attenuating the decline of physical function in aged organisms.However,selective and effective clearance of senescent cells of different cell types has proven challenging.Herein,we developed a prodrug strategy to design a new compound based on the increased activity of lysosomalβ-galactosidase(β-gal),a primary characteristic of senescent cells.Our prodrug SSK1 is specifically activated byβ-gal and eliminates mouse and human senescent cells independently of senescence inducers and cell types.In aged mice,our compound effectively cleared senescent cells in different tissues,decreased the senescence-and age-associated gene signatures,attenuated low-grade local and systemic inflammation,and restored physical function.Our results demonstrate that lysosomalβ-gal can be effectively leveraged to selectively eliminate senescent cells,providing a novel strategy to develop anti-aging interventions. | Yusheng Cai Huanhuan Zhou Yinhua Zhu Qi Sun Yin Ji Anqi Xue Yuting Wang Wenhan Chen Xiaojie Yu Longteng Wang Han Chen Cheng Li Tuoping Luo Hongkui Deng | 2020 | Cell Research2020，30，7： | 12 |
| 13 | Liraglutide alleviates cardiac fibrosis through inhibiting P4hα-1 expression in STZ-induced diabetic cardiomyopathy显示文摘Diabetic cardiomyopathy is an important contributor to morbidity and mortality of diabetic patients by causing heart failure.Interstitial and perivascular fibrosis plays a crucial role in diabetic cardiomyopathy.However,there is a lack of effective specific treatments available for diabetic cardiomyopathy.In the present study,we aim to explore the effects of Liraglutide,a GLP-1 analogue,on diabetic cardiomyopathy in STZ-induced diabetic rats fed with high-fat diet.A total of 60 male Wistar rats were randomly assigned to three groups,i.e.normal group,model group,and Liraglutide group,with 20 rats in each group.Serum levels of TC,TG,LDL-C,NEFA,and hydroxyproline were measured using commercial kits.Cardiac function was evaluated by QRS waves,LVEDd,LVESd,and LVEF.Myocardial fibrosis was measured by immunohistochemistry.Our results demonstrated that chronic administration of Liraglutide decreased the level of blood glucose and significantly alleviated lipid metabolic disturbance compared with the model group.Furthermore,Liraglutide was found to improve the damaged cardiac function.In line with this,we also found that the alleviation of cardiac dysfunction was associated with the decreased fibrosis in diabetic myocardial tissues,which was reflected by the decreased expressions of P4hα-1,COL-1,COL-3,MMP-1,and MMP-9.Our results thus suggest that Liraglutide might have a myocardial protective effect by inhibiting P4hα-1-mediated myocardial fibrosis. | Tong Zhao Huiqiang Chen Fei Xu Juan Wang Yusheng Liu Xiaowei Xing Linlin Guo Mingxiang Zhang Qinghua Lu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，3： | 9 |
| 14 | Provenance of the Paleoproterozoic Hutuo Group basal conglomerates and Neoarchean crustal growth in the Wutai Mountains,North China Craton:Evidence from granite and quartzite pebble zircon U-Pb ages and Hf isotopes显示文摘Zircon U-Pb ages(SHRIMP and LA-ICPMS) and Lu-Hf isotope data(LA-ICPMS) are presented for two granite and two quartzite pebbles from the basal conglomerates of the Sijizhuang Formation in the Hutuo Group from the Wutai Mountains area in the North China Craton.These two granite pebbles give zircon 207 Pb/206 Pb ages of 2513±8 Ma and 2527±8 Ma respectively,which are consistent with the emplacement ages of the Wangjiahui grey granite and Guangmingsi or Shifo granite in the Wutai Mountains.Detrital zircons from those two quartzite pebbles are mostly 2550-2490 Ma old with lesser number of 2800-2550 Ma grains,which is similar to the ages of detrital zircons from quartzites in the Gaofan Subgroup of the Neoarchean Wutai Group.Thus,the pebbles in the Hutuo Group basal conglomerates were derived locally from Wutai Mountains Neoarchean sources.Zircons from the Sijizhuang Formation conglomerate granite and quartzite pebbles mostly have positive ε Hf(t) values,a minority with ε Hf(t) values like model depleted mantle(DM) of the same age,but with most showing DM model ages 200-100 Ma.This indicates that most of the source materials were derived from the mantle within the previous 200 million years,whereas some are derived from 2550-2510 Ma juvenile crustal additions.This additional evidence suggests that in the North China Craton there was important initial polycyclic crustal formation and cratonization in the late Neoarchaean,prior to superimposed Palaeoproterozoic orogenic cycles. | DU LiLin YANG ChongHui WANG Wei REN LiuDong WAN YuSheng SONG HuiXia GAO LinZhi GENG YuanSheng HOU KeJun | 2012 | Science China Earth Sciences2012，55，11： | 8 |
| 15 | Correlation of CD105 and Vascular Endothelial Growth Factor in Laser-induced Choroidal Neovascularization in Rats显示文摘Purpose: Choroidal neovascularization (CNV) plays an important role in pathogenesis of age-related macular degeneration (AMD), ocular histoplasmosis syndrome (OHS) and so on. However, mechanisms of CNV formation are not fully understood. The aim of this study is to investigate the correlation between expressions of CD105 and vascular endothelial growth factor (VEGF) in experimental laser-induced CNV in rats. Methods: CNV model was established by 532 nm laser photocoagulation in Brown-Norway rats. The expression of CD105 and VEGF in CNV was observed by immunohistochemistry at 3, 7, 14, 21, 28 and 56 days after laser photocoagulation. The image analysis was performed with the professional software of Image-Pro Plus. Results: Fluorescein angiography showed fluorescein leakage in CNV from days 7 to 56 after photocoagulation. VEGF expression was mainly observed in vascular endothelial cells, ganglion cells, inner nuclear layers and retinal pigment epithelial cells in normal retina and vascular endothelial cells in normal choroid of the rats. On day 3 after photocoagulation, VEGF began to express in laser-induced lesions. VEGF was strongly expressed in CNV after 7 days (P<0.05) and decreased after 14 days (P>0.05). CD105 was initially presented in CNV at 7 days and obviously expressed at 14 days after photocoagulation (P<0.05). Four weeks later, when angiogenesis tended toward inactive status, expression of CD105 was markedly decreased (P>0.05). There was notablely direct correlation between CD105-positive-microvessel density and positively semiquantitative scoring of VEGF in the CNV(r=0.989, P<0.01). Conclusions: There is direct correlation between the expression of CD105 and VEGF in the laser-induced CNV in rat. It suggests that CD105 and VEGF might participate in the new blood vessel formation and promote the growth of CNV. | Jianfeng Xu Yusheng Wang Xiumei Yang Peng Zhang Lijun Chen | 2006 | 眼科学报2006，22，3： | 8 |

| 17 | Decision Support System for Adaptive Restoration Control of Transmission System显示文摘The power system restoration control has a higher uncertainty level than the preventive control of cascading failures. In order to ensure the feasibility of the decision support system of restoration control, a decision support framework for adaptive restoration control of transmission system is proposed, which can support the coordinated restoration of multiple partitions, coordinated restoration of units and loads, and coordination of multi-partition decision-making process and actual restoration process. The proposed framework is divided into two layers, global coordination layer and partition optimization layer. The upper layer partitions the transmission system according to the power outage scenario, constantly and dynamically adjusts the partitions during the restoration process, and optimizes the time-space decision-making of inter-partition connectivity. For each partition, the lower layer pre-selects restoration targets according to the estimated restoration income, optimizes the corresponding restoration paths, and evaluates the restoration plans according to the expected net income per unit of power consumption. During the restoration process, if the restoration operation such as energizing the outage branch fails, the current restoration plan will be adaptively switched to the sub-optimal one or re-optimized if necessary. The framework includes two operation modes, i.e., the on-line operation mode and training simulation mode, and provides an information interaction interface for collaborative restoration with related distribution systems. The effectiveness and adaptability of the proposed framework is demonstrated by simulations using the modified IEEE 118-bus system. | Ze Li Yusheng Xue Haohao Wang Lili Hao | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，4： | 6 |
| 18 | An antibody against Siglec-15 promotes bone formation and fracture healing by increasing TRAP^(+)mononuclear cells and PDGF-BB secretion显示文摘Osteoporosis(OP)is a common age-related disease characterized by a deterioration of bone mass and structure that predisposes patients to fragility fractures.Pharmaceutical therapies that promote anabolic bone formation in OP patients and OP-induced fracture are needed.We investigated whether a neutralizing antibody against Siglec-15 can simultaneously inhibit bone resorption and stimulate bone formation.We found that the multinucleation of osteoclasts was inhibited in SIGLEC-15 conditional knockout mice and mice undergoing Siglec-15 neutralizing antibody treatment.The secretion of platelet-derived growth factor-BB(PDGF-BB),the number of tartrate-resistant acid phosphatase-positive(TRAP+)mononuclear cells,and bone formation were significantly increased in the SIGLEC-15 conditional knockout mice and antibody-treated mice.The anabolic effect of the Siglec-15 neutralizing antibody on bone formation was blunted in mice with Pdgfb deleted in TRAP-1'cells.These findings showed that the anabolic effect of the Siglec-15 neutralizing antibody was mediated by elevating PDGF-BB production of TRAP4 mononuclear cells.To test the therapeutic potential of the Siglec-15 neutralizing antibody,we injected the antibody in an ovariectomy-induced osteoporotic mouse model,which mimics postmenopausal osteoporosis in women,and in two fracture healing models because fracture is the most serious health consequence of osteoporosis.The Siglec-15 neutralizing antibody effectively reduced bone resorption and stimulated bone formation in estrogen deficiency-induced osteoporosis.Of note,the Siglec-15 neutralizing antibody promoted intramembranous and endochondral ossification at the damaged area of cortical bone in fracture healing mouse models.Thus,the Siglec-15 neutralizing antibody shows significant translational potential as a novel therapy for OP and bone fracture. | Gehua Zhen Yang Dan Ruomei Wang Ce Dou Qiaoyue Guo Melissa Zarr Linda N.Liu Lieping Chen Ruoxian Deng Yusheng Li Zengwu Shao Xu Cao | 2021 | Bone Research2021，9，4： | 6 |
| 19 | A 23 GHz high-temperature superconducting microstrip filter for radio astronomy显示文摘This paper reports a 6-pole high-temperature superconducting (HTS) microstrip bandpass filter for radio astronomy applications. The filter has a center frequency of 23 GHz and a bandwidth the 2 GHz. We have made many efforts, such as adopting 0.25-mm-thick substrate, carefully designing the housing box and filter layout, to solve the problems in realizing a K-band planar filter. A special straight-line half-wavelength resonator (center-widen resonator) was also designed to reduce the insertion loss of the filter. The measured results showed a midband insertion loss of 0.11 dB with a ripple of 0.4 dB, and a return loss better than 11.5 dB. Good agreement was obtained between simulated and measured results. | GAO Lu GUO Jin WANG YueHui YU Tao ZHANG Qiang LI ChunGuang ZHANG XueQiang LI Hong LI JunJie LI WuXia GU ChangZhi MENG JiBao FENG Ji HE YuSheng | 2009 | Chinese Science Bulletin2009，54，19： | 6 |
