1Coding metamaterials, digital metamaterials and programmable metamaterials显示文摘Metamaterials are artificial structures that are usually described by effective medium parameters on the macroscopic scale,and these metamaterials are referred to as‘analog metamaterials’.Here,we propose‘digital metamaterials’through two steps.First,we present‘coding metamaterials’that are composed of only two types of unit cells,with 0 and p phase responses,which we name‘0’and‘1’elements,respectively.By coding‘0’and‘1’elements with controlled sequences(i.e.,1-bit coding),we can manipulate electromagnetic(EM)waves and realize different functionalities.The concept of coding metamaterials can be extended from 1-bit coding to 2-bit coding or higher.In 2-bit coding,four types of unit cells,with phase responses of 0,p/2,p,and 3p/2,are required to mimic the‘00’,‘01’,‘10’and‘11’elements,respectively.The 2-bit coding has greater freedom than 1-bit coding for controlling EM waves.Second,we propose a unique metamaterial particle that has either a‘0’or‘1’response controlled by a biased diode.Based on this particle,we present‘digital metamaterials’with unit cells that possess either a‘0’or‘1’state.Using a field-programmable gate array,we realize digital control over the digital metamaterial.By programming different coding sequences,a single digital metamaterial has the ability to manipulate EM waves in different manners,thereby realizing‘programmable metamaterials’.The above concepts and physical phenomena are confirmed through numerical simulations and experiments using metasurfaces.Tie Jun Cui Mei Qing Qi Xiang Wan Jie Zhao Qiang Cheng 2014Light(Science & Applications)2014,3,1:130
2Scutellaria baicalensis, the golden herb from the garden of Chinese medicinal plants显示文摘Scutellaria baicalensis Georgi, or Chinese skullcap, has been widely used as a medicinal plant in China for thousands of years, where the preparation from its roots is called Huang-Qin. It has been applied in the treatment of diarrhea, dysentery, hypertension, hemorrhaging, insomnia,inflammation and respiratory infections. Flavones such as baicalin, wogonoside and their aglycones baicalein wogonin are the major bioactive compounds extracted from the root of S. baicalensis. These flavones have been reported to have various pharmacological functions, including anti-cancer,hepatoprotection, antibacterial and antiviral, antioxidant,anticonvulsant and neuroprotective effects. In this review,we focus on clinical applications and the pharmacological properties of the medicinal plant and the flavones extracted from it. We also describe biotechnological and metabolic methods that have been used to elucidate the biosynthetic pathways of the bioactive compounds in Scutellaria.Qing Zhao Xiao-Ya Chen Cathie Martin 2016Science Bulletin2016,61,18:59
3Trends in Lipids Level and Dyslipidemia among Chinese Adults, 2002-2015显示文摘Objective To investigate the trends of lipid profiles and dyslipidemia among Chinese adults from 2002 to 2015.Methods Data were collected from three nationally representative cross-sectional surveys.Fasting venous blood samples were collected and serum lipids were tested by biochemical analysis and enzymatic determination.Lipid levels and the prevalence of dyslipidemia among adults were analyzed with complex sampling weighting adjustment for age and gender.Results The weighted means of TC, TG, and LDL-c significantly increased linearly from 3.93, 1.12, and 2.12 mmol/L in 2002 to 4.59, 1.41, and 2.78 mmol/L in 2010 and then to 4.63, 1.47, and 2.87 mmol/L in 2015, respectively;by contrast, HDL-c levels decreased significantly from 1.30 mmol/L to 1.26 mmol/L over the same period.Similar trends in mean non-HDL-c and lipid-related ratios were observed.The weighted dyslipidemia prevalence linearly increased;in particular, hypercholesterolemia increased from 1.6% to 5.6% and then to 5.8%, hypertriglyceridemia increased from 5.7% to 13.6% and then to 15.0%, low HDL-c increased from 18.8% to 35.5% and then to 24.9%, and high LDL-c increased from 1.3% to 5.6% and then to 7.2%(P for trend <0.001).Conclusion Dyslipidemia increased among Chinese adults from 2002 to 2015.Development of a comprehensive strategy to decrease lipid levels in this population is urgently required.SONG Peng Kun MAN Qing Qing LI Hong PANG Shao Jie JIA Shan Shan LI Yu Qian HE Li ZHAO Wen Hua ZHANG Jian 2019Biomedical and Environmental Sciences2019,32,8:45

6Effect of hepatocyte apoptosis induced by TNF-α on acute severe hepatitis in mouse models显示文摘AIM To study the effect of hepatocyteapoptosis and necrosis induced by TNF-α on thepathogenesis of acute severe hepatitis(ASH).METHODS The model of ASH was prepared inD-galactosamine(GAIN)sensitized BALB/c miceby injection of either endotoxin(ET)or tumornecrosis factor-α(TNF-α).Morphologicalchanges of apoptotic hepatocytes were studiedby both light and electron microscope and in siteend labeling method(ISEL).Molecular biologicalchanges of DNA ladder were observed byelectrophoresis of extract from liver tissues.Biochemical changes were measured by alanineaminotransferase(ALT),asparticaminotransferase(AST)and TNF-α.The relationbetween apoptosis and necrosis was evaluatedsimultaneously.RESULTS The sequence of hepatocyteapoptosis,necrosis,and final death from ASHwas observed both in GAIN/ET and GAIN/TNF-agroup.Apoptosis was prominent at 3.5 h and 5 hafter injection of inducer,while necrosis becamedominant at 9 h after challenge.The appearanceof apoptosis was earlier in GAIN/TNF-α groupthan that in GAIN/ ET group.Pretreatment ofmice with antiTNF IgG1 may completely preventthe liver injury induced by GalN/ET.CONCLUSION TNF-α can cause liver damageby inducing hepatic apoptosis and necrosis inmice with endotoxemia.Guo Qing Zang Xia Qiu Zhou Hong Yu Qing Xie Guo Ming Zhao Bin Wang Qing Guo Yue Qin Xiang Dan Liao Department of Infectious Diseases,Rujin Hospital,Shanghai Second Medical University,Shanghai 200025,China 2000World Journal of Gastroenterology2000,6,5:30
7The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity.Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping 2016Biomedical and Environmental Sciences2016,29,1:29

11Human umbilical cord mesenchymal stem cells promote peripheral nerve repair via paracrine mechanisms显示文摘Human umbilical cord-derived mesenchymal stem cells(h UCMSCs) represent a promising young-state stem cell source for cell-based therapy. h UCMSC transplantation into the transected sciatic nerve promotes axonal regeneration and functional recovery. To further clarify the paracrine effects of h UCMSCs on nerve regeneration, we performed human cytokine antibody array analysis, which revealed that h UCMSCs express 14 important neurotrophic factors. Enzyme-linked immunosorbent assay and immunohistochemistry showed that brain-derived neurotrophic factor, glial-derived neurotrophic factor, hepatocyte growth factor, neurotrophin-3, basic fibroblast growth factor, type I collagen, fibronectin and laminin were highly expressed. Treatment with h UCMSC-conditioned medium enhanced Schwann cell viability and proliferation, increased nerve growth factor and brain-derived neurotrophic factor expression in Schwann cells, and enhanced neurite growth from dorsal root ganglion explants. These findings suggest that paracrine action may be a key mechanism underlying the effects of h UCMSCs in peripheral nerve repair.Zhi-yuan Guo Xun Sun Xiao-long Xu Qing Zhao Jiang Peng Yu Wang 2015Neural Regeneration Research2015,10,4:26

13Indoor Allergen Levels and Household Distributions in Nine Cities Across China显示文摘Objective Chinese allergic subjects have high levels of sensitization to house dust mite(HDM) and other indoor allergens. This study quantifies common indoor allergen levels in Chinese households. Methods Dust samples were collected from nine cities. Major allergens Der p 1 and Der f 1 from Dermatophagoides pteronyssinus and D. farinae, and specific antigens of Blomia tropicalis, Tyrophagus putrescentiae, Acarus siro, and cockroach species Blattella germanica and Periplaneta americana were measured by ELISA. Results HDM allergens were found in dust samples from bedding in 95% of the Chinese households. The median levels varied from <0.006 to 9.2 μg/g of dust, depending on the city. The percentages of households having HDM allergen levels associated with the risk of developing allergy sensitization and asthma were 65% and 25%, respectively. Specific antigens of the storage mite and cockroach were only found in samples from the southern and tropical regions of China. Levels of mite allergens were generally higher in samples from bedding compared to samples from the living room, even for storage mites, whereas levels of cockroach antigens were higher in the living room samples. Conclusion HDM allergens are present in bedding dust samples from most Chinese households. Cities in southern and central China have relatively high levels of HDM major allergens compared to cities in northern and western China. Antigens of storage mites and cockroaches are not as common as HDM allergens.ZHENG Yi Wu LAI Xu Xin ZHAO De Yu ZHANG Chun Qing CHEN Jian Jun ZHANG Luo WEI Qing Yu CHEN Shi LIU En Mei NORBACK Dan GJESING Birgitte ZHONG Nan Shan SPANGFORT D.Michael 2015Biomedical and Environmental Sciences2015,28,10:24
14Expert consensus on the diagnosis and treatment of heat stroke in China显示文摘Heat stroke(HS)is a fatal disease caused by thermal damage in the body,and it has a very high mortality rate.In 2015,the People’s Liberation Army Professional Committee of Critical Care Medicine published the first expert consensus on HS in China,Expert consensus on standardized diagnosis and treatment for heat stroke.With an increased understanding of HS and new issues that emerged during the HS treatment in China in recent years,the 2015 consensus no longer meet the requirements for HS prevention and treatment.It is necessary to update the consensus to include the latest research evidence and establish a new consensus that has broader coverage,is more practical and is more in line with China’s national conditions.This new expert consensus includes new concept of HS,recommendations for laboratory tests and auxiliary examinations,new understanding of diagnosis and differential diagnosis,On-site emergency treatment and In-hospital treatment,translocation of HS patients and prevention of HS.Shu-Yuan Liu Jing-Chun Song Han-Ding Mao Jin-Bao Zhao Qing Song 2020Military Medical Research2020,7,1:24
15Recent advances in biosynthesis of bioactive compounds in traditional Chinese medicinal plants显示文摘Plants synthesize and accumulate large amount of specialized(or secondary) metabolites also known as natural products, which provide a rich source for modern pharmacy. In China, plants have been used in traditional medicine for thousands of years. Recent development of molecular biology, genomics and functional genomics as well as high-throughput analytical chemical technologies has greatly promoted the research on medicinal plants. In this article, we review recent advances in the elucidation of biosynthesis of specialized metabolites in medicinal plants,including phenylpropanoids, terpenoids and alkaloids. These natural products may share a common upstream pathway to form a limited numbers of common precursors, but are characteristic in distinct modifications leading to highly variable structures. Although this review is focused on traditional Chinese medicine, other plants with a great medicinal interest or potential are also discussed. Understanding of their biosynthesis processes is critical for producing these highly value molecules at large scale and low cost in microbes and will benefit to not only human health but also plant resource conservation.Lei Yang Changqing Yang Chenyi Li Qing Zhao Ling Liu Xin Fang Xiao-Ya Chen 2016Science Bulletin2016,61,1:23
16Constraining quantitatively the timing and process of continent-continent collision using magmatic record: Method and examples显示文摘Based on the main driving force of plate motion(the slab pull force generated by the descent of the oceanic plate in subduction zones) and the three primary mechanisms for magma generation(adding fluid, increasing temperature, and decreasing pressure), the continent-continent collisional process has been divided into three stages, including initial collision, ongoing collision, and tectonic transition. These stages are characterized by normal calc-alkaline andesitic magma(dehydration of the oceanic crust to release fluids), the migration of calc-alkaline magma toward the trench(dehydration of the oceanic crust or an increase in temperature) or small-scale crust-derived peraluminous magma(heat from intra-crustal shearing), and extensive magmatism with compositional diversity induced by slab break-off(increasing temperature and decreasing pressure), respectively.On the basis of the obtained age of slab break-off, the timing of the initial continent-continent collision can be quantitatively back-dated using the convergence rate, depth of slab break-off, and subduction angle. The spatio-temporal migration of the magmatic activity of the Gangdese Batholith, the onset of magmatic flare-up, and the increase of magma temperature at 52–51Ma documented by the volcanic rocks of the Linzizong Pana Formation were most likely the result of the break-off of the Yarlung-Zangbo Neo-Tethyan oceanic lithosphere at approximately 53 Ma. This proposed age of slab break-off suggests that the initial India-Asia collision likely occurred at approximately 55–54 Ma, which is consistent with the collision ages constrained by other abundant geological data(60–55 Ma). This magmatic method has been applied to the Bitlis orogenic belt in southern Turkey in the Arabia-Eurasia continental collision zone, yielding an age range of approximately 29–22 Ma for the initial Arabia-Asia continental collision that is close to the collision ages recently obtained by apatite fission-track dating(approximately20 Ma) and regional tectonic shortening(approximately 27 Ma). The intense folding of the Upper Cretaceous and the angular unconformity between the overlying Linzizong volcanic rocks in the southern Lhasa Terrane(90.69 Ma) are not related to the initial continental collision between India and Asia, but can be interpreted as the consequences of the strong coupling between the hot and young subducting oceanic crust immediately south of the spreading ridge and the overriding lithosphere or the subduction of the Neo-Tethys oceanic plateaux or seamounts. The tectonic event documented by the angular unconformity between the Linzizong Dianzhong Formation and the Nianbo Formation lasted approximately 3 Ma and likely marks the initial India-Asia collision. The significant deceleration of the Indian continent at approximately 51 Ma can be attributed to the disappearance of the slab pull force in the subduction zone due to the break-off of the Yarlung-Zangbo Neo-Tethyan oceanic lithosphere. The descent of the eclogitized lower crust of the northern Indian continent provides the main driving force for the current northward motion of Indian plate. The weak deformation of the lithospheric plate in the overriding plate of the India-Asia collisional zone between 60 and 40 Ma can be attributed to the high-angle subduction related to the rollback of the Yarlung-Zangbo Neo-Tethyan oceanic lithosphere after the initial India-Asia continental collision, the presence of the thick crust and high elevation on the southern margin of the Lhasa Terrane, and the decoupling between the mid-upper and lower crust and between the lower crust and lithospheric mantle of the Indian continent.ZHU DiCheng WANG Qing ZHAO ZhiDan 2017Science China Earth Sciences2017,60,6:23
17The 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 2019Molecular Plant2019,12,7:23

20Isolation and characterization of dengue virus serotype 2 from the large dengue outbreak in Guangdong, China in 2014显示文摘Dengue has been well recognized as a global public health threat,but only sporadic epidemics and imported cases were reported in recent decades in China.Since July 2014,an unexpected large dengue outbreak has occurred in Guangdong province,China,resulting in more than 40000 patients including six deaths.To clarify and characterize the causative agent of this outbreak,the acute phase serum from a patient diagnosed with severe dengue was subjected to virus isolation and high-throughput sequencing(HTS).Traditional real-time RT-PCR and HTS with Ion Torrent PGM detected the presence of dengue virus serotype 2(DENV-2).A clinical DENV-2 isolate GZ05/2014 was obtained by culturing the patient serum in mosquito C6/36 cells.The complete genome of GZ05/2014 was determined and deposited in Gen Bank under the access number KP012546.Phylogenetic analysis based on the complete envelope gene showed that the newly DENV-2 isolate belonged to Cosmopolitan genotype and clustered closely with other Guangdong strains isolated in the past decade.No amino acid mutations that are obviously known to increase virulence or replication were identified throughout the genome of GZ05/2014.The high homology of Guangdong DENV-2 strains indicated the possibility of establishment of local DENV-2 circulation in Guangdong,China.These results help clarify the origin of this epidemic and predict the future status of dengue in China.ZHAO Hui ZHAO Ling Zhai JIANG Tao LI Xiao Feng FAN Hang HONG Wen Xin ZHANG Yu ZHU Qin YE Qing TONG Yi Gang CAO Wu Chun ZHANG Fu Chun QIN Cheng Feng 2014Science China(Life Sciences)2014,57,12:21
