| 1 | Water quality assessment in Qu River based on fuzzy water pollution index method显示文摘A fuzzy improved water pollution index was proposed based on fuzzy inference system and water pollution index. This method can not only give a comprehensive water quality rank,but also describe the water quality situation with a quantitative value, which is convenient for the water quality comparison between the same ranks. This proposed method is used to assess water quality of Qu River in Sichuan, China. Data used in the assessment were collected from four monitoring stations from 2006 to 2010. The assessment results show that Qu River water quality presents a downward trend and the overall water quality in 2010 is the worst. The spatial variation indicates that water quality of Nanbashequ section is the pessimal. For the sake of comparison, fuzzy comprehensive evaluation and grey relational method were also employed to assess water quality of Qu River. The comparisons of these three approaches' assessment results show that the proposed method is reliable. | Ranran Li Zhihong Zou Yan An | 2016 | Journal of Environmental Sciences2016，28，12： | 30 |
| 2 | The wide-area difference system for the regional satellite navigation system of COMPASS显示文摘The regional satellite navigation system of COMPASS (Phase I) provides both open services and authorized services. Authorized services offer differential corrections and integrity information to users to support higher positioning, navigation and timing precision. Experimenting with real data, positioning accuracy is estimated with a 3GEO/4IGSO COMPASS constellation. The results show that with dual-frequency and single-frequency pseudo-range measurements, the positioning errors are respectively 8 and 10 m (RMS) for open service users, while for authorized users, the errors are 4 and 5 m (RMS), respectively. The COMPASS constellation geometry may cause large error to occur in the height component by 7-9 m for dualor single-frequency users, which can be effectively reduced with the differential corrections supplied by the authorized services. Multipath errors are identified and corrected for COMPASS, resulting in 25% positioning accuracy improvement for dual-frequency users and 10% improvement for single-frequency users. | CAO YueLing HU XiaoGong WU Bin ZHOU ShanShi LIU Li SU RanRan CHANG ZhiQiao HE Feng ZHOU JianHua | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，7： | 21 |
| 3 | Prenatal and early life home environment exposure in relation to preschool children's asthma, allergic rhinitis and eczema in Taiyuan, China显示文摘Prenatal and early life home environment might be related to children’s asthma or allergic diseases later in life.A cross-sectional epidemiological study was designed and a questionnaire survey was performed in 3700 preschool children in urban areas in Taiyuan,Shanxi Province,China.Questions on children’s asthma and allergic diseases from the International Study on Asthma and Allergies in Childhood(ISAAC)were integrated with questions on home environment from the Swedish Dampness in Buildings and Health(DBH)study,appropriately modified for Chinese life habits.By multivariate regression analyses controlling for age,gender,heredity,location in urban/suburban or rural areas,environmental tobacco smoke(ETS)and breastfeeding,we found that home new furniture(HNF)before birth(referring to 1 year before pregnancy and during pregnancy)was positively associated with wheezing ever(odds ratio(OR)1.23 with 95%CI of 1.03–1.48)and wheezing last 12 months(1.24,1.00–1.54),allergic rhinitis(AR)(1.26,1.06–1.51),and eczema(1.42,1.01–1.99).HNF between 0–1 years old was also positively associated with wheezing last 12 months.Home new decoration(HND)during 0–1 years old was positively associated with AR symptoms and eczema symptoms,more in the last 12 months.Stronger positive associations were found for signs of home mold and dampness with almost all children’s asthmatic and allergic symptoms(OR ranging from 1.23–1.85,P<0.05).By mutual adjustment between HNF before children’s birth and home mold or dampness,all the significance remained unchanged.Prenatal HNF and home mold or dampness was independently associated with children’s asthmatic and allergic diseases later in life. | ZHAO ZhuoHui ZHANG Xin LIU RanRan NORBACK Dan WIESLANDER Gunilla CHEN Jie SUNDELL Jan | 2013 | Chinese Science Bulletin2013，58，34： | 13 |
| 4 | Gene expression signatures for phlegm-dampness constitution of Chinese Medicine显示文摘Dear Editor,The term'individualized medicine'was first used in Biochemistry Individuality in 1956 by Williams(Williams et al.,1956).With the emergence of the post-genome era in the21st century,individualized precision medicine has attracted increasing attention.In traditional Chinese medicine(TCM),there is also concept of individualized medicine,which is known as the Chinese constitutional theory,proposed in the1970s(Wang,2012).According to this theory,the | Lingru Li Juan Feng Haiqiang Yao Lan Xie Yu Chen Lingling Yang Shujuan Hou Shipeng Zhao Ranran Sun Yanling Wu Tongtong Bai Yingshuai Li Ruoxi Yu Ji Wang Qi Wang | 2017 | Science China(Life Sciences)2017，60，1： | 13 |
| 5 | Morphology of platelet Golgi apparatus and their significance after acute cerebral infarction显示文摘Blood samples were harvested from the antecubital vein of 20 fasting patients with acute cerebral infarction at 1, 7 and 15 days after onset to prepare blood platelet suspension. Fasting antecubital vein blood was collected from an additional 20 normal adults as controls. Under transmission elec-tron microscope, platelet Golgi tubules and vesicles became significantly thickened, enlarged, and irregular after acute cerebral infarction. Alpha granules in platelets significantly reduced in number, especially 1 day after cerebral infarction. Under immunoelectron microscopy, a few alpha granules aggregated around Golgi tubules and vesicles after infarction. These results suggested that platelet Golgi apparatus displayed significant morphological changes, which were possibly associated with enhanced synthetic and secretory functions of activated platelets after acute cerebral infarction. This study used Golgi apparatus blocking agent Brefeldin A to block Golgi apparatus in an aim to study the effects of Golgi apparatus on CD40L expression on the surface of activated platelets. Flow cytometry revealed that CD40L expression on activated platelet surfaces decreased significantly when Golgi apparatus was blocked, which indicated that Golgi apparatus participated in the syn-thesis and transport of CD40L to the platelet surface. | Wei Lu Dong Xu Ranran Tu Zhiping Hu | 2013 | Neural Regeneration Research2013，8，23： | 13 |

| 8 | Efficacy and safety of Yinchenwuling powder for hyperlipidemia: a systematic review and Meta-analysis显示文摘OBJECTIVE:To assess the clinical effectiveness and adverse effects of Yinchenwuling powder(YCWLP)in the treatment of hyperlipidemia using Meta-analysis.METHODS:Seven electronic databases were searched for randomized controlled trials designed to evaluate the clinical effectiveness of YCWLP for hyperlipidemia published in any language prior to February 2015.Two reviewers independently identified articles,extracted data,assessed quality,and cross-checked the results.Revman 5.3 was used to analyze the data.RESULTS:Only five randomized controlled trials with poor methodology were included in the analy-sis.The five trials compared YCWLP with conventional lipid-lowering drugs.Meta-analysis indicated that YCWLP was more effective at the levels of total cholesterol and triglycerides,while increasing the level of high-density lipoprotein cholesterol without serious adverse effects.However,it was not more effective than lipid-lowering drugs in reducing low-density lipoprotein cholesterol and improving hemorheology.CONCLUSION:YCWLP appeared to improve lipid levels.However,given the high risk of bias among the trials,we could not conclude that YCWLP was beneficial to patients with hyperlipidemia.More rigorous trials are required to provide stronger evidence for the conclusion. | Yao Haiqiang Zhang Zengliang Wang Ji Zuo Jiacheng Chen Yu Zhu Libing Li Xiaoke Yang Zheng Wang Zisong Sun Ranran Xu Xuanxuan Li Changming Wu Yanling Li Lingru Wang Qi | 2016 | Journal of Traditional Chinese Medicine2016，36，2： | 11 |
| 9 | Synthesis and characterization of NaA zeolite particle as intumescent fiame retardant in chloroprene rubber system显示文摘NaA zeolite with average particle size of 1 m was successfully synthesized by microwave heating. Inu-ences of pre-crystallization time,microwave power and microwave heating time on the synthesis of NaA zeolite were investigated. The as-synthesized sample was characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM) and particle size distribution(PSD) . Thermal and fiame retardant properties as intumescent fiame retardant(IFR) in chloroprene rubber(CR) system,such as thermo-gravimetry(TG),limiting oxygen index(LOI),burning rate(BR) and specic extinction area(SEA) were further investigated by adding NaA zeolite particles to CR. Experimental results show that the thermal stability and LOI value increased while BR and SEA decreased by adding 5 phr NaA zeolite into the 40 phr IFR filled CR system. | Wenhui Yuana Huarong Chen Ranran Chang Li Li | 2011 | Particuology2011，9，3： | 11 |
| 10 | In-situ fabrication of PtSe2/GaN heterojunction for self-powered deep ultraviolet photodetector with ultrahigh current on/off ratio and detectivity显示文摘The research of ultraviolet photodetectors(UV PDs)have been attracting extensive attention,due to their important applications in many areas.In this study,PtSe2/GaN heterojunction is in-situ fabricated by synthesis of large-area vertically standing two-dimensional(2D)PtSe2 film on n-GaN substrate.The PtSe2/GaN heterojunction device demonstrates excellent photoresponse properties under illumination by deep UV light of 265 nm at zero bias voltage.Further analysis reveals that a high responsivity of 193 mA·W^-1,an ultrahigh specific detectivity of 3.8 × 10^14 Jones,linear dynamic range of 155d B and current on/off ratio of^10^8,as well as fast response speeds of 45/102μs were obtained at zero bias voltage.Moreover,this device response quickly to the pulse laser of 266 nm with a rise time of 172 ns.Such high-performanee PtSe2/GaN heteroj u nction UV PD demonstrated in this work is far superior to previously reported results,suggesting that it has great potential for deep UV detection. | Ranran Zhuo Longhui Zeng Huiyu Yuan Di Wu Yuange Wang Zhifeng Shi Tingting Xu Yongtao Tian Xinjian Li Yuen Hong Tsang | 2019 | Nano Research2019，12，1： | 11 |
| 11 | Electrochemical synthesis of nitric acid from air and ammonia through waste utilization显示文摘Commercial nitric acid(HNO3) and ammonia(NH3) are mostly produced through the Ostwald process and the Haber-Bosch process, respectively. However, high energy demand and enormous greenhouse gas accompy these processes. The development of economical and green ways to synthesize HNO3 and NH3 is highly desirable for solving the global energy and environmental crisis. Here, we present two energy-efficient and environmentally friendly strategies to synthesize HNO3 and NH3 at distributed sources, including the electrocatalytic oxidation of N2 in air to HNO3 and the electrocatalytic reduction of residual NO3- contamination in water to NH3. The isotope-labeling studies combined with theoretical calculation reveal the reaction path of the two proposed strategies, confirming the origin of the electrochemical products. Importantly, the electrooxidation-generated NO3- ions may also serve as reactants for the electroreduction synthesis of NH3 in the future. Our work may open avenues for energy-efficient and green production of HNO3 and NH3 at distributed sources. | Yuting Wang Yifu Yu Ranran Jia Chao Zhang Bin Zhang | 2019 | National Science Review2019，6，4： | 10 |
| 12 | Trends in herbgenomics显示文摘From Shen Nong's Herbal Classic(Shennong Bencao Jing) to the Compendium of Materia Medica(Bencao Gangmu) and the first scientific Nobel Prize for the mainland of China, each milestone in the historical process of the development of traditional Chinese medicine(TCM) involves screening, testing and integrating. After thousands of years of inheritance and development,herbgenomics(bencaogenomics) has bridged the gap between TCM and international advanced omics studies, promoting the application of frontier technologies in TCM. It is a discipline that uncovers the genetic information and regulatory networks of herbs to clarify their molecular mechanism in the prevention and treatment of human diseases. The main theoretical system includes genomics, functional genomics, proteomics, transcriptomics, metabolomics, epigenomics, metagenomics, synthetic biology, pharmacogenomics of TCM, and bioinformatics, among other fields. Herbgenomics is mainly applicable to the study of medicinal model plants, genomic-assisted breeding, herbal synthetic biology, protection and utilization of gene resources, TCM quality evaluation and control, and TCM drug development. Such studies will accelerate the application of cutting-edge technologies, revitalize herbal research, and strongly promote the development and modernization of TCM. | Tianyi Xin Yu Zhang Xiangdong Pu Ranran Gao Zhichao Xu Jingyuan Song | 2019 | Science China(Life Sciences)2019，62，3： | 10 |
| 13 | Comparative Genome Analysis of Scutellaria baicalensis and Scutellaria barbata Reveals the Evolution of Active Flavonoid Biosynthesis显示文摘Scutellaria baicalensis(S.baicalensis)and Scutellaria barbata(S.barbata)are common medicinal plants of the Lamiaceae family.Both produce specific flavonoid compounds,including baicalein,scutellarein,norwogonin,and wogonin,as well as their glycosides,which exhibit antioxidant and antitumor activities.Here,we report chromosome-level genome assemblies of S.baicalensis and S.barbata with quantitative chromosomal variation(2 n=18 and 2 n=26,respectively).The divergence of S.baicalensis and S.barbata occurred far earlier than previously reported,and a whole-genome duplication(WGD)event was identified.The insertion of long terminal repeat elements after speciation might be responsible for the observed chromosomal expansion and rearrangement.Comparative genome analysis of the congeneric species revealed the species-specific evolution of chrysin and apigenin biosynthetic genes,such as the S.baicalensis-specific tandem duplication of genes encoding phenylalanine ammonia lyase and chalcone synthase,and the S.barbata-specific duplication of genes encoding 4-Co A ligase.In addition,the paralogous duplication,colinearity,and expression diversity of CYP82 D subfamily members revealed the functional divergence of genes encoding flavone hydroxylase between S.baicalensis and S.barbata.Analyzing these Scutellaria genomes reveals the common and species-specific evolution of flavone biosynthetic genes.Thus,these findings would facilitate the development of molecular breeding and studies of biosynthesis and regulation of bioactive compounds. | Zhichao Xu Ranran Gao Xiangdong Pu Rong Xu Jiyong Wang Sihao Zheng Yan Zeng Jun Chen Chunnian He Jingyuan Song | 2020 | Genomics, Proteomics & Bioinformatics2020，18，3： | 10 |

| 16 | Hypoxia-stressed cardiomyocytes promote early cardiac differentiation of cardiac stem cells through HIF-1α/Jagged1/Notch1 signaling显示文摘Hypoxia is beneficial for the differentiation of stem cells transplanted for myocardial injury,but mechanisms underlying this benefit remain unsolved. Here, we report the impact of hypoxia-induced Jagged1 expression in cardiomyocytes(CMs) for driving the differentiation of cardiac stem cells(CSCs).Forced hypoxia-inducible factor 1α(HIF-1α) expression and physical hypoxia(5% O_2) treatment could induce Jagged1 expression in neonatal rat CMs. Pharmacological inhibition of HIF-1α by YC-1 attenuated hypoxia-promoted Jagged1 expression in CMs. An ERK inhibitor(PD98059), but not inhibitors of JNK(SP600125), Notch(DAPT), NF-κB(PTDC), JAK(AG490), or STAT3(Stattic) suppressed hypoxiainduced Jagged1 protein expression in CMs. c-Kit^+ CSCs isolated from neonatal rat hearts using a magnetic-activated cell sorting method expressed GATA4, SM22α or vWF, but not Nkx2.5 and cTnI.Moreover, 87.3% of freshly isolated CSCs displayed Notch1 receptor expression. Direct co-culture of CMs with BrdU-labeled CSCs enhanced CSCs differentiation, as evidenced by an increased number of BrdU^+/Nkx2.5^+ cells, while intermittent hypoxia for 21 days promoted co-culture-triggered differentiation of CSCs into CM-like cells. Notably, YC-1 and DAPT attenuated hypoxia-induced differentiation.Our results suggest that hypoxia induces Jagged1 expression in CMs primarily through ERK signaling,and facilitates early cardiac lineage differentiation of CSCs in CM/CSC co-cultures via HIF-1α/Jagged1/Notch signaling. | Keke Wang Ranran Ding Yanping Ha Yanan Jia Xiaomin Liao Sisi Wang Rujia Li Zhihua Shen Hui Xiong Junli Guo Wei Jie | 2018 | Acta Pharmaceutica Sinica B2018，8，5： | 7 |
| 17 | Analysis of RDSS positioning accuracy based on RNSS wide area differential technique显示文摘The BeiDou Navigation Satellite System(BDS) provides Radio Navigation Service System(RNSS) as well as Radio Determination Service System(RDSS).RDSS users can obtain positioning by responding the Master Control Center(MCC) inquiries to signal transmitted via GEO satellite transponder.The positioning result can be calculated with elevation constraint by MCC.The primary error sources affecting the RDSS positioning accuracy are the RDSS signal transceiver delay,atmospheric trans-mission delay and GEO satellite position error.During GEO orbit maneuver,poor orbit forecast accuracy significantly impacts RDSS services.A real-time 3-D orbital correction method based on wide-area differential technique is raised to correct the orbital error.Results from the observation shows that the method can successfully improve positioning precision during orbital maneuver,independent from the RDSS reference station.This improvement can reach 50% in maximum.Accurate calibration of the RDSS signal transceiver delay precision and digital elevation map may have a critical role in high precise RDSS positioning services. | XING Nan SU RanRan ZHOU JianHua HU XiaoGong GONG XiuQiang LIU Li HE Feng GUO Rui REN Hui HU GuangMing ZHANG Lei | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，10： | 6 |
