| 2 | The Reference Genome Sequence of Scutellaria baicalensis Provides Insights into the Evolution of Wogonin Biosynthesis显示文摘Scutellaria baicalensis Georgi is important in Chinese traditional medicine where preparations of dried roots,'Huang Qin,' are used for liver and lung complaints and as complementary cancer treatments. We report a high-quality reference genome sequence for S. baicalensis where 93% of the 408.14-Mb genome has been assembled into nine pseudochromosomes with a super-N50 of 33.2 Mb. Comparison of this sequence with those of closely related species in the order Lamiales, sesamum indicum and Salvia splendens,revealed that a specialized metabolic pathway for the synthesis of 4'-deoxyflavone bioactives evolved in the genus Scu-tellaria. We found that the gene encoding a specific cinnamate coenzyme A ligase likely obtained its newfunc- tion following recent mutations, and that four genes encoding enzymes in the 4'-deoxyflavone pathway are present as tandem repeats in the genome of S. baicalensis. Further analyses revealed that gene duplications, segmental duplication, gene amplification, and point mutations coupled to gene neo- and subfunctionaliza-tions were involved in the evolution of 4'-deoxyflavone synthesis in the genus Scutellaria. Our study not only provides significant insight into the evolution of specific flavone biosynthetic pathways in the mint family, Lamiaceae, but also will facilitate the development of tools for enhancing bioactive productivity by metabolic engineering in microbes or by molecular breeding in plants. The reference genome of S. baicalensis is also useful for improving the genome assemblies for other members of the mint family and offers an important foundation for decoding the synthetic pathways of bioactive compounds in medicinal plants. | Qing Zhao Jun Yang Meng-Ying Cui Jie Liu Yumin Fang Mengxiao Yan Wenqing Qiu Huiwen Shang Zhicheng Xu Reheman Yidiresi Jing-Ke Weng Tomas Pluskal Marielle Vigouroux Burkhard Steuernagel Yukun Wei Lei Yang Yonghong Hu Xiao-Ya Chen Cathie Martin | 2019 | Molecular Plant2019,12,7: | 23 |
| 3 | Anti-inflammatory and anti-thrombogenic effects of atorvastatin in acute ischemic stroke显示文摘Atorvastatin decreases inflammation and thrombogenesis in patients with carotid artery plaque. Atorvastatin is administered to lower lipid levels, but its anti-inflammatory and anti-thrombogenic effects remain unclear. Eighty-nine patients from northeastern China with acute ischemic stroke caused by large-artery atherosclerosis were randomly divided into the study and control groups. All patients received routine treatment, including antiplatelet therapy, circulatory support, and symp-tomatic treatment. The study group (n=43) also received daily atorvastatin 20 mg/d, and the control group (n=46) received daily placebo pills containing glucose. After 4 weeks, the levels of C-reactive protein, fibrinogen, and D-dimer were significantly lower in the study group than in the control group. Decreases in the levels of C-reactive protein, fibrinogen, and D-dimer were not associated with de-creases in the levels of triacylglycerol and low-density lipoprotein cholesterol. These results suggest that atorvastatin reduces inflammation and thrombogenesis independent of its lipid-lowering effects in patients with acute ischemic stroke caused by large-artery atherosclerosis. | Lianqiu Min Shuai Shao Xiaoning Wu Lin Cong Ping Liu Haiping Zhao Yumin Luo | 2013 | Neural Regeneration Research2013,8,23: | 19 |
| 4 | Correlation between tongue manifestations and glucose, total cholesterol, and high-density lipoprotein cholesterol in patients with acute cerebral infarction显示文摘OBJECTIVE: To analyze the association between tongue manifestations and the levels of glucose (GLU), total cholesterol(TCH), and high-density lipoprotein cholesterol(HDL-C) in subjects with acute cerebral infarction.METHODS: Hospitalized patients with first unilateral cerebral infarction in the Neurological Department of Xuanwu Hospital were included and the correlation between tongue fur color, fur nature,and the levels of GLU,TCH, HDL-C were analyzed.RESULTS: HDL level in the thin fur group was higher than that in the thick fur group(P=0.02). The difference in the levels of GLU,TCH, and HDL-C among the groups was significant(P<0.05), classified in terms of slippery, moist, and dry fur. Further comparison between the groups by Student-Newman-Keuls test showed that GLU level in the dry fur group was the highest. Moreover, the TCH level in the slippery fur group was higher than the other two groups.CONCLUSION: A correlation between tongue manifestations and GLU, TCH, HDL-C was identified in the patients with acute cerebral infarction. | Ping Liu Li Gao Juexian Song Haiping Zhao XiaoguangWu Liyuan Huang Pingping Wang Yumin Luo | 2014 | Journal of Traditional Chinese Medicine2014,34,2: | 14 |

| 7 | A methodology for 3D modeling and visualization of geological objects显示文摘Geological body structure is the product of the geological evolution in the time dimension, which is presented in 3D configuration in the natural world. However, many geologists still record and process their geological data using the 2D or 1D pattern, which results in the loss of a large quantity of spatial data. One of the reasons is that the current methods have limitations on how to express underground geological objects. To analyze and interpret geological models, we present a layer data model to organize different kinds of geological datasets. The data model implemented the unification expression and storage of geological data and geometric models. In addition, it is a method for visualizing large-scaled geological datasets through building multi-resolution geological models rapidly, which can meet the demand of the operation, analysis, and interpretation of 3D geological objects. It proves that our methodology is competent for 3D modeling and self-adaptive visualization of large geological objects and it is a good way to solve the problem of integration and share of geological spatial data. | ZHANG LiQiang TAN YuMin KANG ZhiZhong RUI XiaoPing ZHAO YuanYuan LIU Liu | 2009 | Science China Earth Sciences2009,52,7: | 9 |
| 8 | Creep behavior of EPS composite soil显示文摘EPS composite soil is one type of premixed lightweight fills studied by numerous researchers.However,one aspect that has not been fully understood is the creep behaviors which may have significant effect on the design and application of EPS composite soil.In this paper,the results of a series of oedometer creep tests and triaxial undrained creep tests on EPS composite soil were presented.Four main influencing factors were identified and their effects on the creep behaviors of EPS composite soil were studied.Three well established creep models,namely,Findley model,Singh & Mitchell model,and Mesri model,were used to simulate the creep behavior of EPS composite soil.This study shows that the Findley creep model fits the test results the best.A semi-empirical creep model was also proposed to model the creep behavior under axisymmetric conditions.In this model,the creep strain was divided into instant and viscous elastic strain as well as instant and viscous plastic strain which were simulated by element models and empirical equations,respectively.It was shown that the proposed creep model was able to precisely predict the creep strain of EPS composite soil. | GAO HongMei CHEN YuMin LIU HanLong LIU JinYuan CHU Jian | 2012 | Science China(Technological Sciences)2012,55,11: | 7 |
| 9 | A constitutive model for the state-dependent behaviors of rockfill material considering particle breakage显示文摘The particle breakage during specimen compaction had more significant influence on the position of the breakage critical-state line(BCSL)of Tacheng rockfill material(TRM)in the e-lnp’plane than the particle breakage during shearing,based on the large-scale triaxial compression tests on TRM in a wide range of densities and pressures.The state-dependent dilatancy and the plastic modulus were correlated to the breakage index,based on the formulations of the BCSL of TRM in the e-lnp’plane.The state-dependent model considering particle breakage was proposed for TRM within the framework of the generalized plasticity theory.The proposed model contained fourteen material constants.The test data of TRM from Group A were adopted to determine these material constants,while the test data from Group B were used independently to validate the model predictive capacity.The comparisons between model simulations and test data illustrated that the model with consideration of particle breakage could well represent the stress-strain behaviors of TRM,e.g.,the strain hardening and volumetric contraction behaviors at a loose state and the strain softening and volumetric expansion behaviors at a dense state,and also the particle breakage behaviors of TRM. | XIAO Yang LIU HanLong YANG Gui CHEN YuMin JIANG JingShan | 2014 | Science China(Technological Sciences)2014,57,8: | 6 |
| 10 | An experiment-library least-squares method on on-line coal element contents analysis显示文摘A new experiment-library least-squares(experiment-LLs) method used in the neutron inelastic-scattering and thermal-capture analysis(NITA) technique for on-line coal analysis was developed,which has significantly decreased the non-linear radiation effects.In this method,sixty samples with preset elemental contents were made,from whose experimental spectra twenty single-element spectrum libraries corresponding to twenty kinds of coal were built using the least-squares method.The spectrum of the unknown sample was analyzed based on these twenty libraries to estimate its element contents.With the initial estimated result,the procedure of developing library and analysis was iterated to build a new library with the closest element contents to the unknown sample.Hence the experiment-LLs method can reduce non-linear radiation effects.The experiment-LLs method was performed on an improved coal analysis system which was equipped with a long-life 14 MeV pulsed-neutron generator,a bulk BGO detector with a temperature controller,a moisture meter and coal-smoothing device.The precisions of this system for ash content,water content,volatile content and calorific value have reached 1.0wt%,0.5wt%,1.0wt%,350 kJ/kg,respectively. | WANG HuiDong LU JingBin LU YuPing YANG Dong MA KeYan YANG Kang LIU YuMin CHENG DaoWen | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,11: | 6 |
| 11 | Distinct beneficial effect of Sn on the corrosion resistance of Cr-Mo low alloy steel显示文摘In this work,the beneficial effect of Sn addition on the corrosion resistance mechanism of Cr-Mo low alloy steel was studied.Results demonstrated that Sn improves the corrosion resistance of the steel matrix mainly by influencing the microstructural transformation.Sn addition and the synergistic effect of Sn,Cr,and Mo promote the formation of α-FeOOH,SnO_(2),SnO,Cr(OH)_(3),and molybdates,lead to the improved protection and stability of the rust layer.This synergistic effect also endows the inner rust layer with cation selectivity,preventing the further penetration of Cl-and inhibiting the localized corrosion of steel. | Meihui Sun Xiaojia Yang Cuiwei Du Zhiyong Liu Yong Li Yumin Wu Hongyu San Xiandong Su Xiaogang Li | 2021 | Journal of Materials Science & Technology2021,,22: | 6 |
| 12 | Protective effects of remote ischemic preconditioning in rat hindlimb on ischemia- reperfusion injury显示文摘Three cycles of remote ischemic pre-conditioning induced by temporarily occluding the bilateral femoral arteries (10 minutes) prior to 10 minutes of reperfusion were given once a day for 3 days before the animal received middle artery occlusion and reperfusion surgery. The results showed that brain infarct volume was significantly reduced after remote ischemic pre-conditioning. Scores in the forelimb placing test and the postural reflex test were significantly lower in rats having undergone remote ischemic pre-conditioning compared with those who did not receive remote ischemic pre-conditioning. Thus, neurological function was better in rats having undergone remote ischemic pre-conditioning compared with those who did not receive remote ischemic pre-conditioning. These results indicate that remote ischemic pre-conditioning in rat hindlimb exerts protective effects in ischemia-reperfusion injury. | Ying Zhang Xiangrong Liu Feng Yan Lianqiu Min Xunming Ji Yumin Luo | 2012 | Neural Regeneration Research2012,7,8: | 5 |
| 13 | Whole-genome resequencing of Osmanthus fragrans provides insights into flower color evolution显示文摘Osmanthus fragrans is a well-known ornamental plant that has been domesticated in China for 2500 years.More than 160 cultivars have been found during this long period of domestication,and they have subsequently been divided into four cultivar groups,including the Yingui,Jingui,Dangui,and Sijigui groups.These groups provide a set of materials to study genetic evolution and variability.Here,we constructed a reference genome of O.fragrans‘Liuyejingui’in the Jingui group and investigated its floral color traits and domestication history by resequencing a total of 122 samples,including 119 O.fragrans accessions and three other Osmanthus species,at an average sequencing depth of 15×.The population structure analysis showed that these 119 accessions formed an apparent regional cluster.The results of linkage disequilibrium(LD)decay analysis suggested that varieties with orange/red flower color in the Dangui group had undergone more artificial directional selection;these varieties had the highest LD values among the four groups,followed by the Sijigui,Jingui,and Yingui groups.Through a genome-wide association study,we further identified significant quantitative trait loci and genomic regions containing several genes,such as ethylene-responsive transcription factor 2 and Arabidopsis pseudoresponse regulator 2,that are positively associated with petal color.Moreover,we found a frameshift mutation with a 34-bp deletion in the first coding region of the carotenoid cleavage dioxygenase 4 gene.This frameshift mutation existed in at least one site on both alleles in all varieties of the Dangui group.The results from this study shed light on the genetic basis of domestication in woody plants,such as O.fragrans. | Hongguo Chen Xiangling Zeng Jie Yang Xuan Cai Yumin Shi Riru Zheng Zhenqi Wang Junyi Liu Xinxin Yi Siwei Xiao Qiang Fu Jingjing Zou Caiyun Wang | 2021 | Horticulture Research2021,8,1: | 5 |
| 14 | Injectable dual glucose-responsive hydrogel-micelle composite for mimicking physiological basal and prandial insulin delivery显示文摘For type 1 and advanced type 2 diabetic patients, insulin replacement therapy with simulating on-demand prandial and basal insulin secretion is the best option for optimal glycemic control. However, there is no insulin delivery system yet could mimic both controlled basal insulin release and rapid prandial insulin release in response to real-time blood glucose changes. Here we reported an artificial insulin delivery system, mimicking physiological basal and prandial insulin secretion, to achieve real-time glycemic control and reduce risk of hypoglycemia. A phenylboronic acid(PBA)/galactosyl-based glucose-responsive insulin delivery system was prepared with insulin-loaded micelles embedded in hydrogel matrix. At the hyperglycemic state, both the hydrogel and micelles could swell and achieve rapid glucose-responsive release of insulin, mimicking prandial insulin secretion.When the glucose level returned to the normal state, only the micelles partially responded to glucose and still released insulin gradually. The hydrogel with increased crosslinking density could slow down the diffusion speed of insulin inside, resulting in controlled release of insulin and simulating physiological basal insulin secretion. This hydrogel-micelle composite insulin delivery system could quickly reduce the blood glucose level in a mouse model of type 1 diabetes, and maintain normal blood glucose level without hypoglycemia for about 24 h. This kind of glucose-responsive hydrogel-micelle composite may be a promising candidate for delivery of insulin in the treatment of diabetes. | Juan Lv Gang Wu Ying Liu Chang Li Fan Huang Yumin Zhang Jinjian Liu Yingli An Rujiang Ma Linqi Shi | 2019 | Science China Chemistry2019,62,5: | 5 |
| 15 | Novel slack-based robust scheduling rule for a semiconductor manufacturing system with uncertain processing time显示文摘The NP-hard scheduling problems of semiconductor manufacturing systems(SMSs) are further complicated by stochastic uncertainties. Reactive scheduling is a common dynamic scheduling approach where the scheduling scheme is refreshed in response to real-time uncertainties. The scheduling scheme is overly sensitive to the emergence of uncertainties because the optimization of performance(such as minimum make-span) and the system robustness cannot be achieved simultaneously by conventional reactive scheduling methods. To improve the robustness of the scheduling scheme, we propose a novel slack-based robust scheduling rule(SR) based on the analysis of robustness measurement for SMS with uncertain processing time. The decision in the SR is made in real time given the robustness. The proposed SR is verified under different scenarios, and the results are compared with the existing heuristic rules. Simulation results show that the proposed SR can effectively improve the robustness of the scheduling scheme with a slight performance loss. | Juan LIU Fei QIAO Yumin MA Weichang KONG | 2018 | Frontiers of Engineering Management2018,5,4: | 5 |
| 16 | Effectiveness of flesh-moistening paste in psoriasis vulgaris patients with symptom pattern of blood stasis:a randomized and parallel-controlled trial显示文摘OBJECTIVE:To evaluate the efficacy and safety of flesh-moistening paste for treating psoriasis vulgaris in patients with blood stasis pattern in terms of Traditional Chinese Medicine(TCM).METHODS:Eudipleural rashes on both the left and right side of the same patients with psoriasis vulgaris,diagnosed via TCM as blood stasis pattern,were selected as the targeted skin lesions.A randomized,double-blind,parallel-controlled,multicenter controlled trial was conducted.The targeted skin lesions were categorized into either the treatment or control group.The treatment group used the flesh-moistening paste;the control group used a placebo.Both the paste and the placebo were topically applied twice daily for eight weeks.The patients were examined biweekly to evaluate the effects.The two groups were compared in terms of the psoriasis area and severity index(PASI)of the targeted skin lesions,which is scored according to erythema,desquamation,infiltration,area,pruritus,and improvement of skin barrier function.Adverse events were recorded during the study period.SPSS 21.0 was used to analyze the data.RESULTS:Fifty-six patients were enrolled between February 2016 and October 2017.Two were complicated by cardio-cerebrovascular disease and were excluded;thus,54 outpatients were finally enrolled in the study.Four dropped out during the study period:three failed to complete their follow-up visits for unknown reasons,and one exited due to an adverse event.The final trial comprised 50 of the 56 originally selected patients,with a 92.6%completion rate.After 8 weeks of treatment,the targeted skin lesion scores differed significantly(P<0.05).The PASI scores of the targeted skin lesions differed significantly beginning at week 6(P<0.05).The treatment group presented better results than those of the control group.Only one patient had an adverse reaction associated with the treatment.Improvements in skin barrier function differed significantly(P<0.05).CONCLUSION:The flesh-moistening paste demonstrated a reliable curative effect and safety for treating psoriasis vulgaris in patients with blood stasis patterns.The topical paste improved the barrier function of the skin lesions. | Guo Xinwei Lang Na Li Guanru Li Ping Qu Jianhua Zhou Dongmei Wang Ping Cang Zhang Deng BingXu Lou Weihai Xu Jingna Lan Haibing Liu Yumin Zhang Weishu Sun Liyun | 2020 | Journal of Traditional Chinese Medicine2020,40,6: | 4 |
| 17 | Evolution and Domestication Footprints Uncovered from the Genomes of Coix显示文摘Coix lacryma-jobi,a plant species closely related to Zea and Sorghum,is an important food and medicinal crop in Asia.However,no reference genome of this species has been reported,and its exact phylogeny within the Andropogoneae remains unresolved.Here,we generated a high-quality genome assembly of coix comprising~1.73 Gb with 44485 predicted protein-coding genes.We found coix to be a typical diploid plant with an overall 1-to-1 syntenic relationship with the Sorghum genome,despite its drastic genome expansion(~2.3-fold)due mainly to the activity of transposable elements.Phylogenetic analysis revealed that coix diverged with sorghum~10.41 million years ago,which was~1.49 million years later than the divergence between sorghum and maize.Resequencing of 27 additional coix accessions revealed that they could be unambiguously separated into wild relatives and cultivars,and suggested that coix experienced a strong genetic bottleneck,resulting in the loss of about half of the genetic diversity during domestication,even though many traits have remained undomesticated.Our data not only provide novel comparative genomic and evolutionary insights into the Andropogoneae lineage,but also an important resource that will greatly benefit molecular breeding of this important crop. | Hongbing Liu Junpeng Shi Zexi Cai Yumin Huang Menglu Lv Huilong Du Qiang Gao Yi Zuo Zhaobin Dong Wei Huang Rui Qin Chengzhi Liang Jinsheng Lai Weiwei Jin | 2020 | Molecular Plant2020,13,2: | 4 |
| 18 | Circular RNA circCCNB1 inhibits the migration and invasion of nasopharyngeal carcinoma through binding and stabilizing TJP1 mRNA显示文摘Nasopharyngeal carcinoma(NPC)is a malignant tumor that usually occurs in people from Southeast Asia and Southern China.NPC is prone to migration and invasion,leading to poor prognosis.A large number of circular RNAs(circ RNAs)exacerbate the process of metastasis in NPC;however,their underlying mechanisms remain unclear.We found that the circular RNA circ CCNB1,encoded by the oncogene CCNB1,was downregulated in NPC biopsies and cell lines.In vitro assays show that circ CCNB1 inhibits NPC cell migration and invasion.Moreover,circ CCNB1 induces a protein,nuclear factor 90(NF90),to bind and prolong the half-life of tight junction protein 1(TJP1)m RNA.Upregulation of TJP1 enhances tight junctions between cancer cells and inhibits NPC cell migration and invasion.This study reveals a novel biological function of circ CCNB1 in the migration and invasion of NPC by enhancing the tight junctions of cancer cells by binding to NF90 proteins and TJP1 m RNA,and may provide a potential therapeutic target for NPC. | Mengyao Zhao Yian Wang Fenghua Tan Lingyun Liu Xiangchan Hou Chunmei Fan Le Tang Yongzhen Mo Yumin Wang Qijia Yan Zhaojian Gong Zheng Li Qianjin Liao Can Guo He Huang Xi Zeng Guiyuan Li Zhaoyang Zeng Wei Xiong Fuyan Wang | 2022 | Science China(Life Sciences)2022,65,11: | 4 |

| 20 | All-dielectric three-element transmissive Huygens’ metasurface performing anomalous refraction显示文摘Metasurfaces have pioneered a new avenue for advanced wave-front engineering.Among the various types of metasurfaces,Huygens'metasurfaces are thought to be a novel paradigm for flat optical devices.Enabled by spectrally overlapped electric resonance and magnetic resonance,Huygens'metasurfaces are imparted with high transmission and full phase coverage of 2π,which makes them capable of realizing high-efficiency wave-front control.However,a defect of Huygens'metasurfaces is that their phase profiles and transmissive responses are often sensitive to the interaction of neighboring Huygens'elements.Consequently,the original assigned phase distribution can be distorted.In this work,we present our design strategy of transmissive Huygens'metasurfaces performing anomalous refraction.We illustrate the investigation of Huygens'elements,realizing the overlapping between an electric dipole and magnetic dipole resonance based on cross-shaped structures.We find that the traditional discrete equidistant-phase design method is not enough to realize a transmissive Huygens'surface due to the interaction between neighboring Huygens'elements.Therefore,we introduce an extra optimization process on the element spacing to palliate the phase distortion resulting from the element interaction.Based on this method,we successfully design unequally spaced three-element transmissive metasurfaces exhibiting anomalous refraction effect.The anomalous refractive angle of the designed Huygens'metasurface is 30°,which exceeds the angles of most present transmissive Huygens'metasurfaces.A transmissive efficiency of 83.5%is numerically derived at the operating wavelength.The far-field electric distribution shows that about 93%of transmissive light is directed along the 30°refractive direction.The deflection angle can be tuned by adjusting the number of Huygens'elements in one metasurface unit cell.The design strategies used in this paper can be inspiring for other functional Huygens'metasurface schemes. | CHANG LIU LEI CHEN TIESHENG WU YUMIN LIU JING LI YU WANG ZHONGYUAN YU HAN YE LI YU | 2019 | Photonics Research2019,7,12: | 3 |
