| 1 | KaKs_Calculator 2.0:A Toolkit Incorporating Gamma-Series Methods and Sliding Window Strategies显示文摘We present an integrated stand-alone software package named KaKs_Calculator 2.0 as an updated version.It incorporates 17 methods for the calculation of nonsynonymous and synonymous substitution rates;among them,we added our modified versions of several widely used methods as the gamma series including γ-NG,γ-LWL,γ-MLWL,γ-LPB,γ-MLPB,γ-YN and γ-MYN,which have been demonstrated to perform better under certain conditions than their original forms and are not implemented in the previous version.The package is readily used for the identification of positively selected sites based on a sliding window across the sequences of interests in 5' to 3' direction of protein-coding sequences,and have improved the overall performance on sequence analysis for evolution studies.A toolbox,including C++ and Java source code and executable files on both Windows and Linux platforms together with a user instruction,is downloadable from the website for academic purpose at http://gffzz6ccd80d7270b40f2swu0ofvkfop966x9b.ffgz.tsg.suse.edu.cn/projects/kakscalculator2/. | Dapeng Wang Yubin Zhang Zhang Zhang Jiang Zhu Jun Yu | 2010 | Genomics, Proteomics & Bioinformatics2010，8，1： | 79 |
| 2 | Risk factors for cervical lymph node metastasis in papillary thyroid microcarcinoma: a study of 1,587 patients显示文摘Objective: The purposes of this study were to identify risk factors for cervical lymph node metastasis and to examine the association between BRAF^(V600E) status and clinical features in papillary thyroid microcarcinoma(PTMC).Methods: A total of 1,587 patients with PTMC, treated in Tianjin Medical University Cancer Institute and Hospital from January2011 to March 2013, underwent retrospective analysis. We reviewed and analyzed factors including clinical results, pathology records, ultrasound results, and BRAF^(V600E) status.Results: Multivariate logistic regression analyses demonstrated that gender(male) [odds ratio(OR) = 1.845, P = 0.000], age(< 45 years)(OR = 1.606, P = 0.000), tumor size(> 6 mm)(OR = 2.137, P = 0.000), bilateralism(OR = 2.011, P = 0.000) and extrathyroidal extension(OR = 1.555, P = 0.001) served as independent predictors of central lymph node metastasis(CLNM).Moreover, CLNM(OR = 29.354, P = 0.000) served as an independent predictor of lateral lymph node metastasis(LLNM). Among patients with a solitary primary tumor, those with tumor location in the lower third of the thyroid lobe or the isthmus were more likely to experience CLNM(P < 0.05). Univariate analyses indicated that CLNM, LLNM, extrathyroidal extension, and multifocality were not significantly associated with BRAF^(V600E) mutation.Conclusions: The present study suggested that prophylactic neck dissection of the central compartment should be considered in patients with PTMC, particularly in men with tumor size greater than 6 mm, age less than 45 years, extrathyroidal extension, and tumor bilaterality. Among patients with PTMC, BRAF^(V600E) mutation is not significantly associated with prognostic factors. For a better understanding of surgical management of PTMC and the risk factors, we recommend multicenter research and long-term follow-up. | Xiangqian Zheng Chen Peng Ming Gao Jingtai Zhi Xiukun Hou Jingzhu Zhao Xi Wei Jiadong Chi Dapeng Li Biyun Qian | 2019 | Cancer Biology & Medicine2019，16，1： | 54 |
| 3 | Ultrafast epitaxial growth of metre-sized single-crystal graphene on industrial Cu foil显示文摘A foundation of the modern technology that uses single-crystal silicon has been the growth of highquality single-crystal Si ingots with diameters up to 12 inches or larger. For many applications of graphene, large-area high-quality(ideally of single-crystal) material will be enabling. Since the first growth on copper foil a decade ago, inch-sized single-crystal graphene has been achieved. We present here the growth, in 20 min, of a graphene film of(5 ×50) cm^2 dimension with >99% ultra-highly oriented grains.This growth was achieved by:(1) synthesis of metre-sized single-crystal Cu(1 1 1) foil as substrate;(2)epitaxial growth of graphene islands on the Cu(1 1 1) surface;(3) seamless merging of such graphene islands into a graphene film with high single crystallinity and(4) the ultrafast growth of graphene film.These achievements were realized by a temperature-gradient-driven annealing technique to produce single-crystal Cu(1 1 1) from industrial polycrystalline Cu foil and the marvellous effects of a continuous oxygen supply from an adjacent oxide. The as-synthesized graphene film, with very few misoriented grains(if any), has a mobility up to ~23,000 cm^2 V^(-1)s^(-1)at 4 K and room temperature sheet resistance of ~230 Ω/□. It is very likely that this approach can be scaled up to achieve exceptionally large and high-quality graphene films with single crystallinity, and thus realize various industrial-level applications at a low cost. | Xiaozhi Xu Zhihong Zhang Jichen Dong Ding Yi Jingjing Niu Muhong Wu Li Lin Rongkang Yin Mingqiang Li Jingyuan Zhou Shaoxin Wang Junliang Sun Xiaojie Duan Peng Gao Ying Jiang Xiaosong Wu Hailin Peng Rodney S.

| 4 | Research progress on silicon/carbon composite anode materials for lithium-ion battery显示文摘Silicon(Si) has been considered as one of the most promising anode material for the next generation lithium-ion batteries(LIBs) with high energy densities, due to its high theoretical capacity, abundant availability and environmental friendliness. However, silicon materials with low intrinsic electric and ionic conductivity suffer from huge volume variation during lithiation/delithiation processes leading to the pulverization of Si and subsequently resulting in severe capacity fading of the electrodes. Coupling of Si with carbon(C) realizes a favorable combination of the two materials properties, such as high lithiation capacity of Si and excellent mechanical and conductive properties of C, making silicon/carbon composite(Si/C) ideal candidates for LIBs anodes. In this review, recent progresses of Si/C materials utilized in LIBs are summarized in terms of structural design principles, material synthesis methods, morphological characteristics and electrochemical performances by highlighting the material structures. The mechanisms behind the performance enhancement are also discussed. Moreover, other factors that affect the performance of Si/C anodes, such as prelithiation, electrolyte additives, and binders, are also discussed. We aim to present a full scope of the Si/C-based anodes, and help understand and design future structures of Si/C anodes in LIBs. | Xiaohui Shen Zhanyuan Tian Ruijuan Fan Le Shao Dapeng Zhang Guolin Cao Liang Kou Yangzhi Bai | 2018 | Journal of Energy Chemistry2018，27，4： | 29 |
| 5 | Stenting for symptomatic intracranial arterial stenosis in China:1-year outcome of a multicentre registry study显示文摘background and purpose A multicentre prospective registry study of individually tailored stenting for a patient with symptomatic intracranial atherosclerotic stenosis(ICAS)combined with poor collaterals in China showed that the short-term safety and efficacy of stenting was acceptable.However,it remained uncertain whether the low event rate could be of a long term.We reported the 1-year outcome of this registry study to evaluate the long-term efficacy of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Methods Patients with symptomatic ICAS caused by 70%-99% stenosis located at the intracranial internal carotid,middle cerebral,intracranial vertebral or basilar arteries combined with poor collaterals were enrolled.Balloon-mounted stent or balloon plus self-expanding stent were selected based on the ease of vascular access and lesion morphology determined by the operators.The primary outcome was the rate of 30-day stroke,transient ischaemic attack and death,and 12-month ischaemic stroke within the same vascular territory,haemorrhagic stroke and vascular death after stenting.results From September 2013 to January 2015,300 patients(ages 58.3±9.78 years)were recruited.Among them,159 patients were treated with balloon-mounted stent and 141 with balloon plus self-expanding stent.During the 1-year follow-up,25 patients had a primary end point event.The probability of primary outcome at 1 year was 8.1%(95% CI 5.3% to 11.7%).In 76 patients with digital subtraction angiography follow-up,27.6%(21/76)had re-stenosis≥50% and 18.4%(14/76)had re-stenosis≥70%.No baseline characteristic was associated with the primary outcome.Conclusion The event rate remains low over 1 year of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Further randomised trial of comparing individually tailored stenting with best medical therapy is needed. | Ning Ma Yong Zhang Jie Shuai Changchun Jiang Qiyi Zhu Kangning Chen Li Liu Baomin Li Xiangqun Shi Lianbo Gao Yajie Liu Feng Wang Yongli Li Tieyan Liu Hongbo Zheng Dapeng Mo Feng Gao Yilong Wang Yongjun Wang Lei Feng Zhongrong Miao | 2018 | Stroke & Vascular Neurology2018，3，3： | 29 |

| 10 | Deep Structural Framework and Genetic Analysis of Gold Concentration Areas in the Northwestern Jiaodong Peninsula, China: A New Understanding based on High-Resolution Reflective Seismic Survey显示文摘The gold concentration areas in the northwestern Jiaodong Peninsula constituted an important gold metallogenetic region in Eastern China during the Mesozoic. The deep geological bodies' texture characteristic is important for exploring the resources thoroughly and understanding the metallogenic process. The detailed textures were revealed using high-resolution seismic profiles through the three major ore-controlling structures-Sanshandao fault zone, Jiaojia fault zone and Zhaoping fault zone. This study aims to establish a deep structural framework of this area. Based on their formation mechanism, the fault structures developed in the area can be divided into regional and local fault structures. The structural styles are characterised by superimposing their compressional, strike-slip and extensional multi-stage activities. The crust is cut by vertical structures corresponding to a left-lateral strike-slip fault system on the surface. Nearby these structures are the arc-shape structures formed by multi-stage magma intrusions into the upper crust. Bounded by the Tancheng–Lujiang and Muping–Jimo fault zones, the current Jiaodong block, developed a series of NE-trending strike-slip fault systems, was probably formed by the assemblage of several obliquely aligned blocks. The intensive magmatism and hydrothermal activity between the blocks induced large-scale mineralisation. It provides a new angle of view for understanding the cratonic destruction and large ore-concentration formed during the Mesozoic. | YU Xuefeng SHAN Wei XIONG Yuxin GENG Ke SUN Yuqin CHI Naijie GUO Baokui LI Dapeng LI Hongkui SONG Yingxin YANG Deping | 2018 | Acta Geologica Sinica(English Edition)2018，92，5： | 19 |
| 11 | Transplantation of neurotrophin-3-transfected bone marrow mesenchymal stem cells for the repair of spinal cord injury显示文摘Bone marrow mesenchymal stem cell transplantation has been shown to be therapeutic in the repair of spinal cord injury. However, the low survival rate of transplanted bone marrow mesenchymal stem cells in vivo remains a problem. Neurotrophin-3 promotes motor neuron survival and it is hypothesized that its transfection can enhance the therapeutic effect. We show that in vitro transfection of neurotrophin-3 gene increases the number of bone marrow mesenchymal stem cells in the region of spinal cord injury. These results indicate that neurotrophin-3 can promote the survival of bone marrow mesenchymal stem cells transplanted into the region of spinal cord injury and potentially enhance the therapeutic effect in the repair of spinal cord injury. | Yuzhen Dong Libin Yang Lin Yang Hongxing Zhao Chao Zhang Dapeng Wu | 2014 | Neural Regeneration Research2014，9，16： | 16 |

| 15 | Paleozoic sedimentary record of the Xing-Meng Orogenic Belt, Inner Mongolia: Implications for the provenances and tectonic evolution of the Central Asian Orogenic Belt显示文摘The Xing-Meng Orogenic Belt is the eastern extension of the Central Asian Orogenic Belt, which marks the boundary between the North China and Siberian blocks. Key information on the collision between these two blocks and the evolution of this orogenic belt at the end of the Paleozoic are preserved in the widely distributed Paleozoic sedimentary sequences. Petrographic studies of the clastic sedimentary rocks from the Ordovician to the Permian in this region have shown that the rocks are mainly greywackes and arkosic sandstones characterized by low maturity, poor sorting and a large number of lithic fragments. Provenances of Paleozoic sandstones are mainly newly accreted crustal materials. Nd model ages range from the Neoproterozoic to the Late Mesoproterozoic. These ages are very different from those of the North China Block, but the change of εNd(t) (from the initial εNd value) is similar to that of igneous rocks in the Xing-Meng Orogen. This result indicates that provenances of these Paleozoic sedimentary rocks mainly arise from the Xing-Meng Orogen itself. These clastic sedimentary rocks mainly consist of inputs of juvenile accreted crustal materials and limited recycled old crusts. Their provenance is controlled by the following three end members: a felsic basement, a partially melted mafic, and a mafic end member. From the point view of lithology, these three end members must have mixed in a ratio of 53:41:5 to form the average composition of the clastic sedimentary rocks. The depositional environment began to change from an arc to an orogen during the Permian, and therefore the collision was complete before the Triassic. This interpretation is consistent with the argument that the final collision time was at the end of the Permian or beginning of the Triassic. | LI DaPeng CHEN YueLong WANG Zhong LIN Yu ZHOU Jian | 2012 | Chinese Science Bulletin2012，57，7： | 15 |

| 17 | Recognition on the forming-vanishing process and underlying mechanisms of the hypoxia off the Yangtze River estuary显示文摘On the basis of compiled multidisciplinary historical data in 2006–2007 and incorporation of relevant simulation results and remote sensing data, we performed an in-depth study of the generation and dissipation process of the hypoxic zone and its distribution morphology and structure off the Yangtze River estuary. Based on the hydrological circulation dynamics, reproduction of phytoplankton(leading to the decomposition of organic matter), and other factors, we comprehensively and systematically investigated the generation and dissipation of the hypoxic zone and underlying mechanisms for the seasonal variation in its position, explored the multi-factorial synergistic reactions during the generation and dissipation process of the hypoxic zone, and revealed the controlled mechanism for the morphology and structure of the hypoxic zone's distribution. Our studies indicate that in the winter and spring seasons, the hydrological environment off the Yangtze River estuary provides a water body with relatively low contents of dissolved oxygen(DO), which is the background for the formation of a hypoxic zone. After entering into the summer season, the hypoxic zone gradually develops towards the north and becomes mature. Because of the impact of the terrain, local decomposition of organic matter, and upwelling of the Kuroshio subsurface water in July–August, the hypoxic zone off the Yangtze River estuary exhibits the characteristics of discontinuous distribution in space and has a south and north 'dual-core' structure in the inner continental shelf. In addition, there is a hypoxic core in the eastern outer continental shelf. The degrees of hypoxia vary for different areas; they are strongest overall in the north, next strongest in the south; they are weakest on the outer continental shelf. In summer, the hypoxic zone in the north is related to the northward differentiation of the southern hypoxic zone and results from local development and intensification. In August, the hypoxic zone in the north reaches its peak, and after September, it rapidly retreats southward and disappears because of weakening stratification. In the fall, there is hypoxic zone along the coast of Zhejiang in the south, and there is also a low-DO area to the southwest of Jeju Island, with both zones disappearing rapidly. In addition, the change of dynamic environment also causes the low-DO area of the outer continental shelf to move outward in the fall. The variation in the intensity of the stratification and its cumulative effects as a barrier of vertical DO transportation over long periods of time have a significant impact on the degree of hypoxia in the hypoxic zone. In addition, the seasonal variations in the size of the stratified region, intensity of each current system/water mass, upwelling, front, and high-value area of phytoplankton biomass jointly restrict the extension of the hypoxic zone in the inner continental shelf and latitudinal(south-north direction) movement of its location off the Yangtze River estuary. The combined effect of dynamic factors, such as that of the Kuroshio subsurface water, causes a low-DO core in the outer continental shelf. The bottom cold water to the north of the East China Sea is the dynamic basis for the formation of the low-DO area to the southwest of Jeju Island during the fall season. The special seabed topography and mud area distribution off the Yangtze River estuary have a certain degree of influence on the development of the hypoxic zone. The generation and dissipation of the hypoxic zone and its distribution morphology off the Yangtze River estuary, and seasonal variation of its structure and position are a result of the synergistic effects of various factors. | WEI QinSheng WANG BaoDong CHEN JianFang XIA ChangShui QU DaPeng XIE LinPing | 2015 | Science China Earth Sciences2015，58，4： | 15 |
| 18 | Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders: executive summary and 2019 update of clinical management of cerebral venous sinus thrombosis显示文摘Aim Cerebral venous sinus thrombosis(CVST)is a less common cerebrovascular disease that predominantly affects young patients.The incidence of CVST is 2-5/10000000/year,accounting for 0.5%-1%of all stroke.To reduce mortality and morbidity associated with CVST,Chinese Stroke Association commissioned the authors to write the current guideline on the management of CVST.Methods PubMed(MEDLINE),CNKI and Wanfang database were searched for studies related to CVST from 1 January 1990 to 31 July 2019.Data were synthesised by evidence tables.Each recommendation was fully discussed by the writing group members and reviewed by Chinese Stroke Association Stroke Fellow Committees.Levels of evidence grading algorithm of Chinese Stroke Association was used to grade each recommendation.results This guideline mainly focuses on the diagnostic evaluation,therapeutic strategies and secondary prevention of CVST.CT/CTV and MRI/MRV are recommended in the initial imaging evaluation of patients with suspected CVST.Anticoagulation therapy with low-molecular weight heparin should be initiated in patients with CVST immediately.After the acute stage,warfarin is recommended for 3-6 months to prevent the recurrence of CVST and other venous thromboembolic events.Conclusions The guideline summarises the current evidence regarding the management of CVST,and provides references for diagnosis,treatment and secondary prevention of CVST in China. | Yuhua Fan Jian Yu Hongbing Chen Jian Zhang Jiangang Duan Dapeng Mo Wenhao Zhu Bo Wang Fubing Ouyang Yicong Chen Linfang Lan Jinsheng Zeng Chinese Stroke Association Stroke Council CVST Guideline Writing Committee | 2020 | Stroke & Vascular Neurology2020，5，2： | 14 |
| 19 | Staged carotid artery angioplasty and stenting for patients with high-grade carotid stenosis with high risk of developing hyperperfusion injury:a retrospective analysis of 44 cases显示文摘Background:Hyperperfusion syndrome(HPS)is a rare but potentially a life-threatening complication after carotid artery angioplasty and stenting(CAS).Staged CAS has been an alternative to prevent HPS.Materials and methods:44 of 908 patients with high-grade internal carotid artery stenosis or near occlusion were at risk of HPS because of poor collateral flow and impaired cerebral blood flow(CBF).They were treated with first(stage 1),followed by a full CAS(stage 2)1 month later.Their 30-day outcomes were tabulated and analysed.Results:During follow-up,1 of the 44(2.2%)patients developed HPS immediately,3(7%)had postprocedural HPS(ie,transcranial Doppler(TCD)>120%)without clinical symptoms and 3(7%)required stenting at stage 1 for carotid dissections.After stage 1,there were significant improvement between the preprocedural and postprocedural CBF(0.98±0.06 vs 0.85±0.05,p<0.05),mean transit time(MTT;1.05±0.05 vs 1.15±0.05,p<0.05),time to peak(TTP;1.04±0.06 vs 1.20±0.06,p<0.05)on CT perfusion(CTP),and CBF(66.41±7.41 vs 44.44±6.43,p<0.05)on TCD.After stage 2,improvement was seen in CBF(1.01±0.07 vs 0.98±0.06,p<0.05),MTT(1.01±0.05 vs 1.05±0.05,p<0.05),TTP(0.99±0.06 vs 1.04±0.06,p<0.05)on CTP and CBF(66.41±7.41 vs 93.78±18.81,p<0.05)on TCD.2 had postoperative increase of middle cerebral artery mean flow velocity of 120%after stage 2 without clinical symptoms.Conclusion:Staged carotid artery stenting probably decreased the chance of developing HPS in this group of selected patients.Although requiring a 2-step intervention,staged CAS may be a safe and effective alternative. | Dapeng Mo Gang Luo Bo Wang Ning Ma Feng Gao Xuan Sun Xiaotong Xu Zhongrong Miao | 2016 | Stroke & Vascular Neurology2016，1，4： | 14 |
| 20 | Varietal identification of tea(Camellia sinensis)using nanofluidic array of single nucleotide polymorphism(SNP)markers显示文摘Apart from water,tea is the world’s most widely consumed beverage.Tea is produced in more than 50 countries with an annual production of approximately 4.7 million tons.The market segment for specialty tea has been expanding rapidly owing to increased demand,resulting in higher revenues and profits for tea growers and the industry.Accurate varietal identification is critically important to ensure traceability and authentication of premium tea products,which in turn contribute to on-farm conservation of tea genetic diversity.Using a set of single nucleotide polymorphism(SNP)markers developed from the expressed sequence tag(EST)database of Camilla senensis,we genotyped deoxyribonucleic acid(DNA)samples extracted from a diverse group of tea varieties,including both fresh and processed commercial loose-leaf teas.The validation led to the designation of 60 SNPs that unambiguously identified all 40 tested tea varieties with high statistical rigor(p<0.0001).Varietal authenticity and genetic relationships among the analyzed cultivars were further characterized by ordination and Bayesian clustering analysis.These SNP markers,in combination with a high-throughput genotyping protocol,effectively established and verified specific DNA fingerprints for all tested tea varieties.This method provides a powerful tool for variety authentication and quality control for the tea industry.It is also highly useful for the management of tea genetic resources and breeding,where accurate and efficient genotype identification is essential. | Wan-Ping Fang Lyndel W Meinhardt Hua-Wei Tan Lin Zhou Sue Mischke Dapeng Zhang | 2014 | Horticulture Research2014，1，1： | 13 |
