2Mesozoic contraction deformation in the Yanshan and northern Taihang mountains and its implications to the destruction of the North China Craton显示文摘Mesozoic contraction deformation in the Yanshan and Taihang mountains is characterized by basement-involved thrust tectonics,basement-cored buckling anticlines and ductile thrust and nappe tectonics.Most of these deformations are orientated west-east,west-northwest and northeast to north-northeast.The contraction deformations began in the Permian,continued through the Triassic and Jurassic and terminated in the Early Cretaceous,and constitute an important part of the destruction of the North China Craton.It is estimated,from balanced cross-section reconstructions,that the north-south shortening of the central part of the Yanshan belt before 135 Ma was around 38%.The initial crust thickness,pre-dating the major contraction deformation in late Paleozoic and early Mesozoic,was estimated to be around 35 km based on paleogeographic characteristics.Assuming that the inferred depth of ductile thrusting deformation,20-25 km,was the crust thickness involved in the contraction deformation,and also assuming that the N-S contraction deformation was accommodated by vertical crust thickening,the thickness of the crust after the contraction deformation was expected to be around 47-50 km.This was the approximate crust thickness required for the eclogitization of the lower crust for delamination.The gravity potential accumulated by the isostatic uplift of the thickened crust,together with the decrease in crustal strength caused by the coeval magmatisms associated with the contraction deformation,led to the subsequent extensional collapse of the middle and upper crust although the regional stress regime associated with the plate interactions remained constant.It is inferred that the Mesozoic contraction deformations in the Yanshan and Taihang mountains were not only a significant tectonic process contributing to the destruction of the craton in middle and upper crust but also stimulated delamination at a deep level and the extension of the shallow crust.In other words,both the suspected delamination of the lower crust and upper mantle and the well constrained extension deformations of the shallow crust in the eastern North China Craton during the late Mesozoic are a consequence of crust thickening due to previous contractions.Extensional deformations could be expected to occur independently in the shallow crust,and are not necessarily associated with or responding to delamination at a deep level.ZHANG ChangHou LI ChengMing DENG HongLing LIU Yang LIU Lei WEI Bo LI HanBin LIU Zi 2011Science China Earth Sciences2011,54,6:40
3An emerging hemorrhagic fever in China caused by a novel bunyavirus SFTSV显示文摘Severe fever with thrombocytopenia syndrome(SFTS) is an emerging hemorrhagic fever in rural areas of China and is caused by a new bunyavirus,SFTSV,named after the disease.The transmission vectors and animal hosts of SFTSV are unclear.Ticks are the most likely transmission vectors and domestic animals,including goats,dogs,and cattle,are potential amplifying hosts of SFTSV.The clinical symptoms of SFTS are nonspecific,but major symptoms include fever,gastrointestinal symptoms,myalgia,dizziness,joint pain,chills,and regional lymphadenopathy.The most common abnormalities in laboratory test results are thrombocytopenia(95%),leukocytopenia(86%),and elevated levels of serum alanine aminotransferase,aspartate aminotransferase,creatine kinase,and lactate dehydrogenase.The fatality rate for SFTS is 12% on average,and the annual incidence of the disease is approximately five per 100000 of the rural population.ZHANG XiaoShuang LIU Yan ZHAO Li LI Bing YU Hao WEN HongLing YU Xue-Jie 2013Science China(Life Sciences)2013,56,8:28

5A Transcriptional Network Promotes Anthocyanin Biosynthesis in Tomato Flesh显示文摘Dietary anthocyanins are important health-promoting antioxidants that make a major contribution to the quality of fruits. It is intriguing that most tomato cultivars do not produce anthocyanins in fruit. However, the purple tomato variety Indigo Rose, which has the dominant Aft locus combined with the recessive atv locus from wild tomato species, exhibits light-dependent anthocyanin accumulation in the fruit skin. Here, we report that Aft encodes a functional anthocyanin activator named SlAN2-like, while atv encodes a nonfunctional version of the anthocyanin repressor SlMYBATV. The expression of SlAN2-like is responsive to light, and the functional SlAN2-like can activate the expression of both anthocyanin biosynthetic genes and their regulatory genes, suggesting that SlAN2-like acts as a master regulator in the activation of anthocyanin biosynthesis. We further showed that cultivated tomatoes contain nonfunctional alleles of SlAN2-like and therefore fail to produce anthocyanins. Consistently, expression of a functional SlAN2-like gene driven by the fruit-specific promoter in a tomato cultivar led to the activation of the entire anthocyanin biosynthesis pathway and high-level accumulation of anthocyanins in both the peel and flesh. Taken together, our study exemplifies that efficient engineering of complex metabolic pathways could be achieved through tissue-specific expression of master transcriptional regulators.Chuanlong Sun Lei Deng Minmin Du Jiuhai Zhao Qian Chen Tingting Huang Hongling Jiang Chang-Bao Li Chuanyou Li 2020Molecular Plant2020,13,1:17
6IL-23-induced macrophage polarization and its pathological roles in mice with imiquimod-induced psoriasis显示文摘Macrophages acquire distinct phenotypes during tissue stress and inflammatory responses.Macrophages are roughly categorized into two different subsets named inflammatory M1 and anti-inflammatory M2 macrophages.We herein identified a unique pathogenic macrophage subpopulation driven by IL-23 with a distinct gene expression profile including defined types of cytokines.The freshly isolated resting mouse peritoneal macrophages were stimulated with different cytokines in vitro,the expression of cytokines and chemokines were detected by microarray,real-time PCR,ELISA and multiple colors flow cytometry.Adoptive transfer of macrophages and imiquimod-induced psoriasis mice were used.In contrast to M1-and M2-polarized macrophages,IL-23-treated macrophages produce large amounts of IL-17A,IL-22and IFN-γ.Biochemical and molecular studies showed that IL-23 induces IL-17A expression in macrophages through the signal transducer and activator of transcription 3(STAT3)-retinoid related orphan receptor-γ T (RORyT)pathway.T-bet mediates the IFN-γ production in IL-23-treated macrophages.Importantly,IL-23-treated macrophages signifi- cantly promote the dermatitis pathogenesis in a psoriasis-like mouse model.IL-23-treated resting macrophages express a distinctive gene expression prolife compared with M1 and M2 macrophages.The identification of IL-23-induced macrophage polarization may help us to understand the contribution of macrophage subpopulation in Th17-cytokines-related pathogenesis.Yuzhu Hou Linnan Zhu Hongling Tian Hai-Xi Sun Ruoyu Wang Lianfeng Zhang Yong Zhao 2018Protein & Cell2018,9,12:16
7Effect of electroacupuncture on brain-derived neurotrophic factor mRNA expression in mouse hippocampus following cerebral ischemia-reperfusion injury显示文摘OBJECTIVE:This work aims to observe the effects of electroacupuncture on brain-derived neurotrophic factor(BDNF) mRNA expression in mouse hippocampus following cerebral ischemia-reperfusion injury.METHODS:The models of mouse cerebral ischemia-reperfusion injury were established.A total of 96 healthy mice were randomly assigned into 4 groups,namely,the sham surgery,model,model + electroacupuncture,and mode + hydergine groups.Mice in the model + electroacupuncture group were treated through electroacupuncture at the Shenshu(BL 23),Geshu(BL 17),and Baihui(GV 20) acupoints.Mice in the model+hydergine group were intragastrically administered with hydergine(0.77 mg/kg-1 · day-1).The levels of BDNF mRNA expressions in the hippocampus were analyzed through a semi-quantitative reverse transcription-polymerase chain reaction assay on days 1 and 7 after the surgeries.RESULTS:BDNF mRNA expressions in the mouse hippocampus of the model group on days 1 and 7 after the surgery were higher than those of the sham surgery group(both P<0.01).On days 1 and 7 of the electroacupuncture treatment,BDNF mRNA expression in the mouse hippocampus of the model + electroacupuncture group was significantly elevated compared with the model group(both P< 0.01) or the model + hydergine group(both P< 0.01).On days 1 and 7 of the hydergine treatment,BDNF mRNA expression in the mouse hippocampus of the model + hydergine group tended to increase compared with the model group;however,statistical significance was not achieved(both P> 0.05).CONCLUSION:Electroacupuncture treatment enhances endogenous BDNF expression,which may improve the survival environment for intracerebral neurons and inhibit the apoptosis of hippocampal cells.Jianxin Zhao Huazhou Xu Yuanxiang Tian Manxiang Hu Hongling Xiao 2013Journal of Traditional Chinese Medicine2013,33,2:14
8Arbuscular mycorrhizal fungal colonization of Glycyrrhiza glabra roots enhances plant biomass,phosphorus uptake and concentration of root secondary metabolites显示文摘Arbuscular mycorrhizal(AM)fungi penetrate the cortical cells of the roots of vascular plants,and are widely distributed in soil.The formation of these symbiotic bodies accelerates the absorption and utilization of mineral elements,enhances plant resistance to stress,boosts the growth of plants,and increases the survival rate of transplanted seedlings.We studied the effects of various arbuscular mycorrhizae fungi on the growth and development of licorice(Glycyrrhiza glabra).Several species of AM,such as Glomus mosseae,Glomus intraradices,and a mixture of fungi(G.mosseae,G.intraradices,G.cladoideum,G.microagregatum,G.caledonium and G.etunicatum)were used in our study.Licorice growth rates were determined by measuring the colonization rate of the plants by the fungi,plant dry biomass,phosphorus concentration and concentration of secondary metabolites.We established two cloned strains of licorice,clone 3(C3)and clone 6(C6)to exclude the effect of genotypic variations.Our results showed that the AM fungi could in fact increase the leaf and root biomass,as well as the phosphorus concentration in each clone.Furthermore,AM fungi significantly increased the yield of certain secondary metabolites in clone 3.Our study clearly demonstrated that AM fungi play an important role in the enhancement of growth and development of licorice plants.There was also a significant improvement in the secondary metabolite content and yield of medicinal compounds from the roots.HongLing LIU Yong TAN Monika NELL Karin ZITTER-EGLSEER Chris WAWSCRAH Brigitte KOPP ShaoMing WANG Johannes NOVAK 2014Journal of Arid Land2014,6,2:13

10Efficient generation of pink-fruited tomatoes using CRISPR/Cas9 system显示文摘Tomato(Solanum lycopersicum)is the leading vegetable crop worldwide and an essential component of a healthy diet(Lin et al.,2014;Du et al.,2017).Fruit color is regarded as one of the most important commercial traits in tomato(The Tomato Genome Consortium,2012).Consumers in different regions have different color preferences.For example,European andLei Deng Hang Wang Chuanlong Sun Qian Li Hongling Jiang Minmin Du Chang-Bao Li Chuanyou Li 2018Journal of Genetics and Genomics2018,45,1:13
11Pediatric reference intervals in China(PRINCE):design and rationale for a large,multicenter collaborative cross-sectional study显示文摘There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory measurands.The project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants. The operation of the PRINCE project has been modified based on the findings in the pilot study toward improving the validity of the PRINCE project and promoting its openness and transparency.Xin Ni Wenqi Song Xiaoxia Peng Ying Shen Yaguang Peng Qiliang Li Yan Wang Lixin Hu Yanying Cai Hong Shang Min Zhao Hong Jiang Yaoguo Huang Runqing Mu Wenxiang Chen Mingting Peng Chuanbao Zhang Jie Zeng Chenbin Li Hongling Yang Yongmei Jiang Jin Xu Guixia Li Hongbing Chen Yun Xiang Sancheng Cao Zhenxin Guo Dapeng Chen 2018Science Bulletin2018,63,24:12
12Mesenchymal stem cells and immune disorders: from basic science to clinical transition显示文摘As a promising candidate seed cell type in regenerative medicine, mesenchymal stem cells (MSCs) have attracted considerable attention. The unique capacity of MSCs to exert a regulatory effect on immunity in an autologous/allergenic manner makes them an attractive therapeutic cell type for immune disorders. In this review, we discussed the current knowledge of and advances in MSCs, including its basic biological properties, i.e., multilineage differentiation, secretome, and immunomodulation. Specifically, on the basis of our previous work, we proposed three new concepts of MSCs, i.e.,“subtotipotent stem cell” hypothesis, MSC system, and “Yin and Yang” balance of MSC regulation, which may bring new insights into our understanding of MSCs. Furthermore, we analyzed data from the Clinical Trials database (http://gffzzd3f38a9638994581h50pwfuoqpofv6vw5.ffgz.tsg.suse.edu.cn) on registered clinical trials using MSCs to treat a variety of immune diseases, such as graft-versus-host disease, systemic lupus erythematosus, and multiple sclerosis. In addition, we highlighted MSC clinical trials in China and discussed the challenges and future directions in the field of MSC clinical application.Shihua Wang Rongjia Zhu Hongling Li Jing Li Qin Han Robert Chunhua Zhao 2019Frontiers of Medicine2019,13,2:12
13Bottom Factors Applied to the Zoning Study of the Risk Levels of Landslides in the Three Gorges Reservoir Area显示文摘Without taking inducing factors into consideration, this paper adopts a quantitative analysis of the bottom factors in the Three Gorges Reservoir area, studies the relationship between the bottom factors and the development of landslides, and then zones the area according to risk levels. The bottom factors adopted in this paper include lithological characters(U_ 1 ), gradient(U_ 2 ), slope form(U_ 3 ), difference of height(U_ 4 ), and slope orientation(U_ 5 ). In 4 650 km 2 of the studied area, the areas of the very high, high, medium and low hazard degree area respectively were 57.94 km 2 , 2 305.15 km 2 , 1 241.6 km 2 , 1 045.31 km 2 . The methodological steps are ① inversion statistic analysis, ② the analysis of contribution ratio and weighing, ③ getting results via fuzzy evaluation of risk levels.QIAO Jianping ZHU Axing WU Caiyan TIAN Hongling 2006Wuhan University Journal of Natural Sciences2006,11,4:12
14Analyses of trends and causes for variations in runoff and sediment load of the Yellow River显示文摘Due to the impacts of globe climate change and human activities,dramatic variations in runoff and sediment load were observed for the Yellow River.Analyses of nearly 65 years' data measured at main hydrologic-stations on the Yellow River from 1950 to 2014 indicated that,except for the Tangnaihai station in the head region,sharp downward trends existed in both the annual runoff and annual sediment load according to the Mann-Kendal trend test;and their abrupt changes occurred in 1986 and in1980,respectively,according to the rank sum test.Factors affecting the changes in the runoff and sediment load were very complicated.Results indicated that the reducing precipitation and the increasing water consumption were the main causes for the runoff decline,while the impoundment of the Longyangxia Reservoir and its combined operation with the Liujiaxia Reservoir exerted a direct bearing on the abrupt change in the annual runoff.In addition to the sediment load decrease associated with the runoff reduction,the reduced storm intensity,the conducted soil erosion control,and the constructed dam buildings all played an important role in the trends and abrupt changes of sediment load decline.Hongling Shi Chunhong Hu Yangui Wang Cheng Liu Huimei Li 2017International Journal of Sediment Research2017,32,2:11

16Identification and Typing of Respiratory Adenoviruses in Guangzhou, Southern China Using a Rapid and Simple Method显示文摘Human adenoviruses (HAdVs), especially HAdV-B3, -E4 and -B7, are associated with Acute Respiratory Disease in Chinese children, and occasionally in adults. In order to establish and document the profiles of the respiratory adenovirus pathogen among children in Guangzhou, Southern China, a rapid, simple and practical method for identification and typing of respiratory adenoviruses was developed and evaluated. One pair of universal PCR primers was designed according to the conserved region of the hexon gene, which can detect not only HAdV-B3, -E4 and -B7, but also HAdV-B14, -F40 and -F41, with a specific 300bp PCR product. Three pairs of type-specific PCR primers were also designed according to the hypervariable regions of the hexon gene to type HAdV-B3, -E4 and -B7 by three independent PCR reactions, making it easy to optimize the PCR conditions. By using this method, one hundred throat swab specimens collected during Oct 2010 to Dec 2011 and suspected of being positive for adenoviral infection were identified and typed for adenoviruses. Of these samples, fifty-five were adenovirus-positive. The most common HAdV type was HAdV-B3, identified in 92.7% of samples, which is not only consistent with the data reported in 2004-2006, but also consistent with the recent report in Hangzhou, eastern China, indicating that HAdV-B3 has been circulating in Guangzhou, and maybe in eastern China, for many years. The method for the respiratory adenovirus identification and typing we developed is rapid, simple and practical, which has a potential in the real-time surveillance of circulating adenovirus strains and also to provide etiological evidence for the adenovirus-relative disease control and prevention in China.Guiyuan Han Hongling Niu Suhui Zhao Bing Zhu Changbing Wang Yungang Liu Mingjie Zhang Shu Yang Feitong Liu Chengsong Wan Qiwei Zhang 2013Virologica Sinica2013,28,2:10

20Chemical comparison of dried rehmannia root and prepared rehmannia root by UPLC-TOF MS and HPLC-ELSD with multivariate statistical analysis显示文摘To identify the chemical differences which lead to the different therapeutic effects of dried rehmannia root(DRR)and prepared rehmannia root(PRR),we compared the chemical composition of decoctions of randomly purchased DRR and PRR using ultra performance liquid chromatography(UPLC)coupled with time-of-fight mass spectrometry and high performance liquid chromatography(HPLC)coupled with evaporative light scattering detection(ELSD)with the aid of multivariate statistical analysis.Both approaches clearly revealed compositional and quantitative differences between DRR and PRR.UPLC-MS data indicated stachyose,rehmaiono-side A(or rehmaionoside B),acteoside(or forsythiaside,or isoacteoside),6-O-coumaroylajugol(or 6-O-E-feruloylajugol,or 6-O-Z-feruloylajugol)as important discriminators between DRR and PRR decoctions.HPLC-ELSD analysis showed that the content of fructose in the decoctions of PRR was about four times greater than that of DRR(P<10^(-5)),while sucrose content in the decoctions of PRR was only about one seventh of that in DRR(P<0.01).Our results suggest that some compounds,such as fructose,stachyose and rehmaionoside,may be responsible for the differing therapeutic effects of DRR and PRR.Furthermore,improvements in quality control for PRR,which is currently lacking in the Chinese Pharmacopoeia,are recommended.Qiande Liang Jing Ma Zengchun Ma Yuguang Wang Hongling Tan Chengrong Xiao Ming Liu Beibei Lu Boli Zhang Yue Gao 2013Acta Pharmaceutica Sinica B2013,3,1:8
