1Immunoregulatory Effects of Ethyl-acetate Fraction of Extracts from Tetrastigma Hemsleyanum Diels et. Gilg on Immune Functions of ICR Mice显示文摘Objective To evaluate the effects of ethyl-acetate fraction (EAF) of extracts from Tetrastigma hemsleyanum Diels et. Gilg (TDG) on immune functions of ICR mice. Methods ICR mice were exposed to different doses of EAF for 15 or 30 days and then their immune functions were analyzed, including ConA-induced splenic lymphocyte transformation, SRBC- induced delayed type hypersensitivity response, serum hemolysin analysis, antibody-producing cells, peritoneal macrophage phagocytized chicken red blood cells, natural killer cell activity, and serum level of cytokines. Results EAF of extracts from TDG at different doses had various effects on immune functions of ICR mice. As compared with the controls, it increased the mouse spleen lymphocyte transformation induced by ConA, the left-hind voix pedis thickness and the number of plague forming cells (PFCs) at the dose of 1.82 mg/mL, 5.48 mg/mL, and 9.12 mg/mL, respectively; increased the ink clearance ability at the dose of 0.91 mg/mL, 1.82 mg/mL, 5.48 mg/mL, and 9.12 mg/mL, respectively; increased the phagocytosis index of mononuclear-macrophages and production of serum interferon-gamma (IFN-γ) at the dose of 5.48 mg/mL; and could promote the production of serum tumor necrosis factor-alpha (TNF-α) at the dose of 9.12 mg/mL. Conclusion EAF of extracts from TDG can regulate mouse immune functions in vivo.CAI-JU XU GANG-QIANG DING JIAN-YUN FU JIA MENG RONG-HUA ZHANG XIAO-MING LOU 2008Biomedical and Environmental Sciences2008,21,4:49
2Massive individual orbital angular momentum channels for multiplexing enabled by Dammann gratings显示文摘Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.Orbital angular momentum(OAM)in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems,with OAM beams acting as information carriers for OAM division multiplexing(OAM-DM).We demonstrate independent collinear OAM channel generation,transmission and simultaneous detection using Dammann optical vortex gratings(DOVGs).We achieve 80/160 Tbit s^(-1) capacity with uniform power distributions along all channels,with 1600 individually modulated quadrature phase-shift keying(QPSK)/16-QAM data channels multiplexed by 10 OAM states,80 wavelengths and two polarizations.DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s^(-1) level.Ting Lei Meng Zhang Yuru Li Ping Jia Gordon Ning Liu Xiaogeng Xu Zhaohui Li Changjun Min Jiao Lin Changyuan Yu Hanben Niu Xiaocong Yuan 2015Light(Science & Applications)2015,4,1:47

6Toripalimab combined with lenvatinib and GEMOX is a promising regimen as first-line treatment for advanced intrahepatic cholangiocarcinoma:a single-center,single-arm,phase 2 study显示文摘Advanced intrahepatic cholangiocarcinoma(ICC)has a dismal prognosis.Here,we report the efficacy and safety of combining toripalimab,lenvatinib,and gemcitabine plus oxaliplatin(GEMOX)as first-line therapy for advanced ICC.Thirty patients with pathologically confirmed advanced ICC received intravenous gemcitabine(1 g/m2)on Days 1 and 8 and oxaliplatin(85 mg/m2)Q3W for six cycles along with intravenous toripalimab(240 mg)Q3W and oral lenvatinib(8 mg)once daily for one year.The expression of programmed death-ligand 1(PD-L1)and genetic status was investigated in paraffin-embedded tissues using immunohistochemistry and whole-exome sequencing(WES)analysis.The primary endpoint was the objective response rate(ORR).Secondary outcomes included safety,overall survival(OS),progression-free survival(PFS),disease control rate(DCR)and duration of response(DoR).As of July 1,2022,the median follow-up time was 23.5 months,and the ORR was 80%.Twenty-three patients achieved partial response,and one achieved complete response.Patients(21/30)with DNA damage response(DDR)-related gene mutations showed a higher ORR,while patients(14/30)with tumor area positivity≥1(PD-L1 staining)showed a trend of high ORR,but without significant difference.The median OS,PFS,and DoR were 22.5,10.2,and 11.0 months,respectively.The DCR was 93.3%.Further,56.7%of patients experienced manageable grade≥3 adverse events(AEs),commonly neutropenia(40.0%)and leukocytopenia(23.3%).In conclusion,toripalimab plus lenvatinib and GEMOX are promising first-line regimens for the treatment of advanced ICC.A phase-III,multicenter,double-blinded,randomized study to validate our findings was approved by the National Medical Products Administration(NMPA,No.2021LP01825).Guo-Ming Shi Xiao-Yong Huang Dong Wu Hui-Chuan Sun Fei Liang Yuan Ji Yi Chen Guo-Huan Yang Jia-Cheng Lu Xian-Long Meng Xin-Ying Wang Lei Sun Ning-Ling Ge Xiao-Wu Huang Shuang-Jian Qiu Xin-Rong Yang Qiang Gao Yi-Feng He Yang Xu Jian Sun Zheng-Gang Ren Jia Fan Jian Zhou 2023Signal Transduction and Targeted Therapy2023,8,4:12
7Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
8Water regime-nitrogen fertilizer incorporation interaction:Field study on methane and nitrous oxide emissions from a rice agroecosystem in Harbin, China显示文摘Water regime and nitrogen(N) fertilizer are two important factors impacting greenhouse gases(GHG) emission from paddy field, whereas their effects have not been well studied in cold region. In this study, we conducted a two-year field experiment to study the impacts of water regime and N fertilizer on rice yields and GHG emissions in Harbin, China, a cold region located in high latitudes. Our results showed that intermittent irrigation significantly decreased methane(CH_4) emission compared with continuous flooding, however,the decrement was far lower than the global average level. The N_2O emissions were very small when flooded but peaked at the beginning of the disappearance of floodwater. The N fertilizer treatments increased CH_4 emissions at low level(75 kg N/ha). But both CH_4 and N_2O emissions were uninfluenced at the levels of 150 kg N/ha and 225 kg N/ha. Rice yields increased under intermittent irrigation and were highest at the level of 150 kg N/ha. From our results, we recommended that the intermittent irrigation and 150 kg N/ha as the ideal water regime-nitrogen fertilizer incorporation for this area to achieve low GHG emissions without impacting rice yields.Wenjun Dong Jia Guo Lijun Xu Zhifeng Song Jun Zhang Ao Tang Xijuan Zhang Chunxu Leng Youhong Liu Lianmin Wang Lizhi Wang Yang Yu Zhongliang Yang Yilei Yu Ying Meng Yongcai Lai 2018Journal of Environmental Sciences2018,30,2:12
9The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
10Hippo/YAP signaling pathway is involved in osteosarcoma chemoresistance显示文摘Background:Osteosarcoma is the most common bone malignancy in children and adolescents,and 20%-30%of the patients suffer from poor prognosis because of individual chemoresistance.The Hippo/yes-associated protein(YAP) signaling pathway has been shown to play a role in tumor chemoresistance,but no previous report has focused on its involvement in osteosarcoma chemoresistance.This study aimed to investigate the role of the Hippo/YAP signaling pathway in osteosarcoma chemoresistance and to determine potential treatment targets.Methods:Using the Cell Titer-Glo Luminescent cell viability assay and flow cytometry analysis,we determined the proliferation and chemosensitivity of YAP-overexpressing and YAP-knockdown osteosarcoma cells.In addition,using western blotting and the real-time polymerase chain reaction technique,we investigated the alteration of the Hippo/YAP signaling pathway in osteosarcoma cells treated with chemotherapeutic agents.Results:Mammalian sterile 20-like kinase 1(MST1) degradation was increased,and large tumor suppressor kinase1/2(LAT51/2) total protein levels were decreased by methotrexate and doxorubicin,which increased activation and nuclear translocation of YAP.Moreover,YAP increased the proliferation and chemoresistance of MG63 cells.Conclusions:The Hippo/YAP signaling pathway plays a role in osteosarcoma chemoresistance,and YAP is a potential target for reducing chemoresistance.Dong-Yu Wang Ya-Nan Wu Jun-Qi Huang Wei Wang Meng Xu Jin-Peng Jia Gang Han Bei-Bei Mao Wen-Zhi Bi 2016Chinese Journal of Cancer2016,35,7:10
11Renal Protective Activity of Hsian-tsao Extracts in Diabetic Rats显示文摘Objective To investigate the renal protective activity of Hsian-tsao Mesona procumbens Hemsl. water extracts in diabetic rats. Methods Thirty Sprague-dawley female rats were randomly divided into three groups (n=10 each), 'control group' with intraperitoneal saline injection, 'diabetic group' with 60 mg of intraperitoneal streptozotocin injection per kg of body weight and 'Hsian-tsao group' with intragastric administration of Hsian-tsao extraction everyday for 4 weeks after intraperitoneal streptozotocin injection. The body weight and blood sugar were measured before and after model induction in the three groups. Thrombospondin-1 (TSP-1) expressions in the kidney were monitored by immunohistochemistry. Kidney ultrastructural changes were also analyzed by using transmission electron microscopy. Results Before diabetic model induction, there were no significant differences among the three groups in body weight and blood sugar. Four weeks after the induction of diabetes, the differences became statistically significant. Electron microscopy also revealed disruption of the foot processes of the podocytes and other damages in diabetic group. These damages were significantly less severe in Hsian-tsao group when compared with the diabetic group. TSP-1 expressions in the kidney were significantly increased in both the diabetic group and Hsian-tsao group, but it was relatively lower in Hsian-tsao group than in diabetic group. Conclusion Our results showed that Hsian-tsao treatment in the diabetic rats effectively prevented the pathological alterations in the kidney and decreased the TSP-1 expression. It was suggested that Hsian-tsao had protective effect on the kidneys of the diabetic rats.MIN YANG ZHENG-PING XU CAI-JU XU JIA MENG GANG-QIANG DING XIAO-MING ZHANG YAN WENG 2008Biomedical and Environmental Sciences2008,21,3:10
12Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world.Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong 2022Science China(Life Sciences)2022,65,9:9
13Alleviation by abscisic acid of Al toxicity in rice bean is not associated with citrate efflux but depends on ABI5-mediated signal transduction pathways显示文摘Under conditions of aluminum(Al) toxicity,which severely inhibits root growth in acidic soils, plants rapidly alter their gene expression to optimize physiological fitness for survival. Abscisic acid(ABA) has been suggested as a mediator between Al stress and gene expression, but the underlying mechanisms remain largely unknown. Here,we investigated ABA-mediated Al-stress responses, using integrated physiological and molecular biology approaches.We demonstrate that Al stress caused ABA accumulation in the root apex of rice bean(Vigna umbellata [Thunb.] Ohwi &Ohashi), which positively regulated Al tolerance. However,this was not associated with known Al-tolerance mechanisms. Transcriptomic analysis revealed that nearly one-third of the responsive genes were shared between the Al-stress and ABA treatments. We further identified a transcription factor, ABI5, as being positively involved in Al tolerance. Arabidopsis abi5 mutants displayed increased sensitivity to Al, which was not related to the regulation of AtALMT1 and AtMATE expression. Functional categorization of ABI5-mediated genes revealed the importance of cell wall modification and osmoregulation in Al tolerance, a finding supported by osmotic stress treatment on Al tolerance. Our results suggest that ABA signal transduction pathways provide an additional layer of regulatory control over Al tolerance in plants.Wei Fan Jia Meng Xu Pei Wu Zhi Xin Yang He Qiang Lou Wei Wei Chen Jian Fen Jin Shao Jian Zheng Jian Li Yang 2019Journal of Integrative Plant Biology2019,61,2:9

15Expression of cyclooxygenase in hyperdynamic portal hypertensive rats显示文摘BACKGROUND: By detecting hemodynamic changes, concentration of plasm prostacyclin ( PGI2) and expression of cyclooxygenase( COX) in vasculature and splanchnic tissues, we evaluated the relative contributions of PGI2 and COX mRNA expression to the hyperdynamic circulatory state in chronic portal hypertensive rats. METHODS: Fifty male Sprague-Dawley rats were divided into 3 groups: intrahepatic portal hypertension (IHPH, n = 18) by injection of CCl4, prehepatic portal hypertension (PHPH, n = 18) by partial stenosis of the portal vein, and sham-operated controls (SO, n =14). Splanchnic hemodynamics was measured by radioactive microsphere techniques and the concentration of PGI2 was detected by specific radioimmunoassay for its stable hydrolysis product 6-keto-PGF1α. Semi-quantitive reverse transcriptase-polyme-rase chain reaction (RT-PCR) was performed to measure the levels of COX-1 mRNA and COX-2 mRNA in the thoracic aorta, superior mesenteric artery( SMA),and small intestine of IHPH, PHPH and SO rats, respectively. RESULTS: Hyperdynamic circulatory state was characterized by increased splanchnic blood flow and decreased splanchnic vascular resistance in IHPH and PHPH rats. The concentration of plasma 6-keto-PGF1α ( pg/ml) in IHPH (1093.75 ± 142.15) and PHPH (897. 42 ± 53. 29) rats was significantly higher than that in SO rats (730.13 ± 98. 67) (P <0.05). The expression of COX-1 mRNA in the thoracic aorta, SMA and small intestine was enhanced, whereas COX-2 mRNA expression was not detected in either of these vessels or the small intestine. The plasma 6-keto-PGF1α concentration and the expression of COX-1 mRNA in these vessels and the small intestine were closely correlated with such hemodynamic parameters as portal venous inflow (PVI), splanchnic vascular resistance (SVR) and free portal venous pressure (FPP) (P<0.05). CONCLUSION: The expression of COX-1 mRNA and the levels of PGI2 were closely related to the hyperdynamic circulatory state of portal hypertensive rats.Hui Cao, Jia Xu, Rong Hua, Fang-Bin Meng, Jiang-Feng Qiu and Zhi-Yong Wu Department of Surgery, Renji Hospital, Shanghai Second Medical University, Shanghai 200127, China 2006Hepatobiliary & Pancreatic Diseases International2006,5,2:8
16Whole genome sequencing of 10K patients with acute ischaemic stroke or transient ischaemic attack: design, methods and baseline patient characteristics显示文摘Background and purpose Stroke is the second leading cause of death worldwide and the leading cause of mortality and long-term disability in China,but its underlying risk genes and pathways are far from being comprehensively understood.We here describe the design and methods of whole genome sequencing(WGS)for 10914 patients with acute ischaemic stroke or transient ischaemic attack from the Third China National Stroke Registry(CNSR-III).Methods Baseline clinical characteristics of the included patients in this study were reported.DNA was extracted from white blood cells of participants.Libraries are constructed using qualified DNA,and WGS is conducted on BGISEQ-500 platform.The average depth is intended to be greater than 30×for each subject.Afterwards,Sentieon software is applied to process the sequencing data under the Genome Analysis Toolkit best practice guidance to call genotypes of single nucleotide variants(SNVs)and insertion-deletions.For each included subject,21 fingerprint SNVs are genotyped by MassARRAY assays to verify that DNA sample and sequencing data originate from the same individual.The copy number variations and structural variations are also called for each patient.All of the genetic variants are annotated and predicted by bioinformatics software or by reviewing public databases.Results The average age of the included 10914 patients was 62.2±11.3 years,and 31.4%patients were women.Most of the baseline clinical characteristics of the 10914 and the excluded patients were balanced.Conclusions The WGS data together with abundant clinical and imaging data of CNSR-III could provide opportunity to elucidate the molecular mechanisms and discover novel therapeutic targets for stroke.Si Cheng Zhe Xu Yang Liu Jinxi Lin Yong Jiang Yilong Wang Xia Meng Anxin Wang Xinying Huang Zhimin Wang Guohua Chen Songdi Wu Zhengchang Jia Yongming Chen Xuerong Qiu Jun Wu Binbin Song Weizhong Ji Zhongping An Wenjun Xue Lili Zhao Yu Geng Hongyan Li Hao Li Yongjun Wang 2021Stroke & Vascular Neurology2021,6,2:8

18Design,methodology,and baseline of whole city‑million scale children and adolescents myopia survey(CAMS)in Wenzhou,China显示文摘Background:Myopia is the most common visual impairment in children and adolescents worldwide.This study described an economical and effective population-based screening pipeline and performed the project of a million scale children and adolescents myopia survey(CAMS),which will shed light on the further study of myopia from the level of epidemiology and precision medicine.Methods:We developed a novel population-based screening pattern,an intelligent screening process and internetbased information transmission and analysis system to carry out the survey consisting of school children in Wenzhou,China.The examination items include unaided distance visual acuity,presenting distance visual acuity,and noncycloplegic autorefraction.Myopia and high myopia were defined as spherical equivalent(SE)≤−1.00 diopters(D)and SE≤−6.00 D,respectively.Next,the reports of the vision checking were automatically sent to parents and the related departments.The CAMS project will be done two to four times annually with the support of the government.An online eyesight status information management system(OESIMS)was developed to construct comprehensive and efficient electronic vision health records(EVHRs)for myopia information inquiry,risk pre-warning,and further study.Results:The CAMS completed the first-round of screening within 30 days for 99.41%of Wenzhou students from districts and counties,in June 2019.A total of 1,060,925 participants were eligible for CAMS and 1,054,251(99.37%participation rate)were selected through data quality control,which comprised 1305 schools,and 580,609,251,050 and 170,967 elementary,middle,and high school students.The mean age of participants was 12.21±3.32 years(6-20 years),the female-to-male ratio was 0.82.The prevalence of myopia in elementary,middle,and high school students was 38.16%,77.52%,and 84.00%,respectively,and the high myopia incidence was 0.95%,6.90%,and 12.98%.Conclusions:The CAMS standardized myopia screening model involves automating large-scale information collection,data transmission,data analysis and early warning,thereby supporting myopia prevention and control.The entire survey reduced 90%of staff,cost,and time consumption compared with previous surveys.This will provide new insights for decision support for public health intervention.Liangde Xu Youyuan Zhuang Guosi Zhang Yunlong Ma Jian Yuan Changseng Tu MiaoMiao Li Wencan Wang Yaru Zhang Xiaoyan Lu Jing Li Xinting Liu Zhengbo Xue Meng Zhou Jie Sun Jinhua Bao Ming Li Fan Lu Hong Wang Jianzhong Su Jia Qu 2021Eye and Vision2021,8,1:7
19Influence of nitric oxide synthase and cyclooxygenase blockade on expression of cyclooxygenase and hemodynamics in rats with portal hypertension显示文摘BACKGROUND : The importance of nitric oxide (NO) in the pathogenesis of portal hypertension (PHT) has been extensively studied, but whether or not prostacyclin (PGI2) plays a role in formation and development of hyperdynamic circutatory state in PHT has not been verified. The present study was undertaken to investigate the possible interaction between prostacyclin (PGI2) and nitric oxide (NO) in the hyperdynamic circulatory state of rats with chronic portal hypertension (PHT), by measuring the hemodynamic changes and expression of cyclooxygenase (COX) mRNA in vessels and small intestine after administration of Nω- nitro-L-arginine (L-NNA) or indomethacin (INDO) either in the short-term (7 days) or long-term (15 days). METHODS: Ninety-seven male Sprague-Dawley rats were divided into three groups: intrahepatic portal hypertension (IHPH) induced by injection of CCl4, prehepatic portal hypertension (PHPH) induced by partial stenosis of the portal vein, and sham-operated controls (SO). Animals of each group received L-NNA or INDO either for 7 or 15 days, with saline as control. Splanchnic hemodynamics was measured by the radioactive microsphere technique. The concentration of NO in serum was determined as the nitrate; nitrite ratio (NO2-/NO3-, μmol/L) by a colorometric method, and that of PGI2 was measured by specific radioimmunoassay for its stable hydrolysis product 6-keto-PGF1α (pg/ml). The reverse transcription- polymerase chain reaction measured the levels of COX-1 mRNA in the superior mesenteric artery, thoracic aorta, and small intestine of these rats.RESULTS: Compared with SO rats, COX-1 mRNA expression and the concentrations of plasma 6-keto- PGF1α and serum NO2-/NO3- were enhanced in both IHPH and PHPH rats; splanchnic vascular resistance (SVR) decreased, but portal venous inflow (PVI) markedly increased (P<0.05). Seven or 15 days of L-NNA treatment reduced COX-1 mRNA expression in these vessels and the small intestine, concomitant with a significant decrease in the concentration of plasma PGI2 and serum NO in IHPH and PHPH rats (P<0.05). At the same time, PVI decreased but SVR increased significantly (P<0.05). In both IHPH and PHPH rats, the COX-1 mRNA expression and the concentration of plasma PGI2 after No synthase (NOS) blockade for 15 days were higher than those for 7 days, whereas the hyperdynamic circulatory state was improved after NOS blockade for 15 days compared with 7 days. The concentration of PGI2 treated by INDO for 15 days was not significantly different from that after 7-day COX blockade, and hemodynamics restored hyperdynamic circulatory state. CONCLUSIONS: The hyperdynamic circulatory state in rats with PHT is correlated with the concentration of serum NO. There is a possible interaction between PGI2 and NO in the hyperhemodynamics of PHT. PGI2 is probably not the mediator in the formation and development of the hyperdynamic circulatory state in rats with chronic PHT.Hui Cao, Jia Xu, Hua Liu, Fang-Bin Meng, Jiang-Feng Qiu and Zhi-Yong Wu Department of Surgery, Renji Hospital, College of Medicine, Shanghai Jiaotong University, Shanghai 200127, China 2006Hepatobiliary & Pancreatic Diseases International2006,5,4:6
20A transcription factor STOP1-centered pathway coordinates ammonium and phosphate acquisition in Arabidopsis显示文摘Phosphorus(P)is an indispensable macronutrient required for plant growth and development.Natural phosphate(Pi)reserves are finite,and a better understanding of Pi utilization by crops is therefore vital for worldwide food security.Ammonium has long been known to enhance Pi acquisition efficiency in agriculture;however,the molecular mechanisms coordinating Pi nutrition and ammonium remains unclear.Here,we reveal that ammonium is a novel initiator that stimulates the accumulation of a key regulatory protein,STOP1,in the nuclei of Arabidopsis root cells under Pi deficiency.We show that Pi deficiency promotes ammonium uptake mediated by AMT1 transporters and causes rapid acidification of the root surface.Rhizosphere acidification-triggered STOP1 accumulation activates the excretion of organic acids,which help to solubilize Pi from insoluble iron or calcium phosphates.Ammonium uptake by AMT1 transporters is downregulated by a CIPK23 protein kinase whose expression is directly modulated by STOP1 when ammonium reaches toxic levels.Taken together,we have identified a STOP1-centered regulatory network that links external ammonium with efficient Pi acquisition from insoluble phosphate sources.These findings provide a framework for developing possible strategies to improve crop production by enhancing the utilization of non-bioavailable nutrients in soil.Wen Hao Tian Jia Yuan Ye Meng Qi Cui Jun Bo Chang Yu Liu GuiXin Li Yun Rong Wu Ji Ming Xu Nicholas P.Harberd Chuan Zao Mao Chong Wei Jin Zhong Jie Ding Shao Jian Zheng 2021Molecular Plant2021,14,9:5
