| 1 | Combined serum hepatoma-specific alpha-fetoprotein and circulating alpha-fetoprotein-mRNA in diagnosis of hepatocellular carcinoma显示文摘BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide, its prognosis is poor, and early detection is of utmost importance. Although alpha-fetoprotein (AFP) is a useful marker for detecting and monitoring HCC development, the false-negative or false-positive rates with AFP alone may be as high as 30%-40% for patients with small HCCs. To enhance the specificity and accuracy of AFP measurements for HCC, we analyzed AFP expression states in livers, detected the hepatoma-specific AFP (HS-AFP) fraction and AFP-mRNA from peripheral blood mononuclear cells, and explored their clinical implications for HCC diagnosis. METHODS: AFP expression and hepatocyte distributions in liver specimens were investigated by an immunohistoche- mical assay. Total RNAs were extracted from circulating blood, synthesized to cDNA through random primers and reverse transcriptase, and fragments of the AFP gene were amplified by a nested-PCR assay. The HS-AFP fraction was separated by lectin-affinity chromatography and its level was detected by radioimmunoassay. RESULTS: The incidence of AFP was 73.3% in HCC tissues and its expression in HCCs with moderate or low differentiation was significantly stronger than that of HCCs with high differentiation (P<0.05). The incidence of AFP gene fragments was 100% in HCCs, and 60% in paracancerous tissues (P<0.01). In the HCC and liver cirrhosis groups, the incidence of HS-AFP was 91.7% and 18% (P<0.01), and of AFP-mRNA was 56.7% and 16% (P<0.01), respectively, and neither was found in controls.HS-AFP or AFP-mRNA was not significantly related to size or number of HCC, but to its differentiation, metastasis, and relapse (P<0.05). CONCLUSIONS: Different AFP expression is present in different parts of HCC tissues. HS-AFP and AFP-mRNA fragments improve sensitivity and specificity, and both are useful markers to diagnose HCC or monitor metastasis and relapse. | Wei Wu, Deng-Fu Yao, Yong-Mei Yuan, Ji-Wei Fan, Xiu-Feng Lu, Xiao-Hua Li, Li-Wei Qiu, Lei Zong and Xin-Hua Wu Research Center of Clinical Molecular Biology, Affiliated Hospital of Nantong University, Nantong 226001, China | 2006 | Hepatobiliary & Pancreatic Diseases International2006,5,4: | 26 |
| 2 | Overview of Citrin Deficiency:SLC25A13 Mutations and the Frequency显示文摘Citrin deficiency,autosomal recessive disorder,caused by mutation of SLC25A13 gene on chromosome 7q21.3 has two major phenotypes:neonatal intrahepatic cholestatic hepatitis(NICCD)and adult-onset type Ⅱ citrullinemia(CTLN2).So far,we have identified 52 SLC25A13 mutations and diagnosed the patients not only in Japan(166 CTLN2 and 238 NICCD) but also in other countries.We have detected 76 Chinese,13 Korean and 15 Vietnamese patients with the same mutations as Japanese,and 13 patients(from Israel,UK,USA or Czech)with mutations different from those found in Japanese,indicating a wide distribution of citrin deficiency.DNA diagnoses of 13 known SLC25A13 mutations revealed that the carrier frequency was high in East Asian populations:Chinese(73/4 600=1/63),Japanese(21/1 372=1/65) and Korean(25/2 690=1/108),suggesting that near by 100 000 East Asians are homozygotes.It is important to find out patients with citrin deficiency,to treat them,and to prevent onset of severe CTLN2. | Keiko Kobayashi Miharu Ushtkai Yuan - Zong Song Hong - Zhi Gao Jian - Sheng Sheng Ayako Tabata Furnihiko Okumura Sayaka lkeda Takeyori Saheki | 2008 | 实用儿科临床杂志2008,23,20: | 26 |

| 5 | Effects of Xinfeng capsule on pulmonary function based on treg-mediated notch pathway in a rat model of adjuvant arthritis显示文摘OBJECTIVE:To observe the impact of xinfeng xapsule(XFC) on pulmonary function in a rat model of adjuvant arthritis(AA) and to investigate the mechanism of action.METHODS:Forty rats were randomly divided into four groups of ten:normal control(NC);model control(MC);tripterygium glycosides tablet(TPT);and xinfeng capsule(XFC).Except for the NC group,AA was induced in all rats by intracutaneous injection of 0.1 mL Freund's complete adjuvant in the right paw on the 19th day.NC and MC groups were given(0.9%) physiological saline.The TPT and XFC groups were given TPT(10 mg/kg) and XFC(1.2 g/kg),respectively.Thirty days after administration,changes in paw edema(E),the arthritis index(AI),pulmonary function,levels of regulatory T-cells(Treg),ultrastructure of lung tissue,and expression of Notch receptors and ligands in lung tissue were observed.RESULTS:In the MC group,E and the AI were increased and pulmonary function significantly decreased;the structure of alveolar type-II cells was damaged;ratios of Treg in peripheral blood were reduced;and expression of Notch receptors such as Notch3 and Notch4 and ligands such as Delta1 in lung tissue were significantly increased whereas expression of Notch1,Jagged1 and Jagged2 were significantly decreased.After intervention with XFC,E and the AI were decreased;pulmonary function was enhanced;the structure of alveolar type-II cells was improved;and expression of Treg,Notch1,Jagged1,Jagged2 was elevated,whereas that of Notch3,Notch4 and Delta1 was reduced.CONCLUSION:XFC can not only inhibit E and the AI and improve joint symptoms,it can also improve pulmonary function and reduce inflammation in lung tissue.These actions could be carried out through increases in the expression of Treg,Notch receptors(Notch1) and ligands(Jagged1,Jagged2),and reductions in the expression of Notch3,Notch4 and Delta1.These phenomena would reduce the deposition of immune complexes and the inflammatory response in lung tissue,thereby improving joint symptoms and pulmonary function. | Lei Wan Jian Liu Chuanbing Huang Yuan Wang Xi Shen Wandong Zhang Guizheng Wang Haixia Fan Yao Ge Ruilian Chen Yunxiang Cao Ruikai Zong Li Lei | 2012 | Journal of Traditional Chinese Medicine2012,32,3: | 17 |
| 6 | Phase 1 clinical trial demonstrated that MUC1 positive metastatic seminal vesicle cancer can be effectively eradicated by modified Anti-MUC1 chimeric antigen receptor transduced T cells显示文摘Recent progress in chimeric antigen receptor-modified T-cell(CAR-T cell) technology in cancer therapy is extremely promising, especially in the treatment of patients with B-cell acute lymphoblastic leukemia. In contrast, due to the hostile immunosuppressive microenvironment of a solid tumor, CAR T-cell accessibility and survival continue to pose a considerable challenge, which leads to their limited therapeutic efficacy. In this study, we constructed two anti-MUC1 CAR-T cell lines. One set of CAR-T cells contained SM3 single chain variable fragment(sc Fv) sequence specifically targeting the MUC1 antigen and co-expressing interleukin(IL) 12(named SM3-CAR). The other CAR-T cell line carried the SM3 sc Fv sequence modified to improve its binding to MUC1 antigen(named p SM3-CAR) but did not co-express IL-12. When those two types of CAR-T cells were injected intratumorally into two independent metastatic lesions of the same MUC1+ seminal vesicle cancer patient as part of an interventional treatment strategy, the initial results indicated no side-effects of the MUC1 targeting CAR-T cell approach, and patient serum cytokines responses were positive. Further evaluation showed that p SM3-CAR effectively caused tumor necrosis, providing new options for improved CAR-T therapy in solid tumors. | Fengtao You Licui Jiang Bozhen Zhang Qiang Lu Qiao Zhou Xiaoyang Liao Hong Wu Kaiqi Du Youcai Zhu Huimin Meng Zhishu Gong Yunhui Zong Lei Huang Man Lu Jirong Tang Yafen Li Xiaochen Zhai Xiangling Wang Sisi Ye Dan Chen Lei Yuan Lin Qi Lin Yang | 2016 | Science China(Life Sciences)2016,59,4: | 16 |
| 7 | High precision in-situ Pb isotopic analysis of sulfide minerals by femtosecond laser ablation multi-collector inductively coupled plasma mass spectrometry显示文摘An in-situ microanalysis of Pb isotopic compositions in sulfide minerals is carried out by using femtosecond laser-ablation multi-collector inductively coupled plasma mass spectrometry(fs LA-MC-ICP-MS).High-temperature-activated carbon was used to filter Hg contained in the carrier gas,which reduced the Hg background signal by 48%and also lowered the detection limit of the analysis.Fractionation and mass discrimination effects existing in the ICP-MS analytical processes were corrected using an internal reference Tl in conjunction with an external reference NIST SRM 610.The proposed method was used to analyze the Pb isotopic compositions of chalcopyrite,pyrite,and sphalerite from the Dulong Sn-Zn-In polymetallic ore district.The results showed that in this ore district,the sulfide minerals and different grains of the same sulfide mineral show a large variation in Pb content up to 1000-fold.The studied pyrites show relatively higher Pb contents and homogeneous Pb isotopic compositions,whereas the sphalerites have low Pb contents but most variable Pb isotopic compositions.It is suggested that the large variation of Pb isotopic composition may reflect a late hydrothermal superimposition on the primary sulfide formation.In addition,radiogenic Pb accumulated by radioactive decay of trace amounts of U over time in the host minerals may also be one of the causes for the large variation range of Pb content and Pb isotopic composition of those low-Pb sphalerites.Chalcopyrite and sphalerite grains with Pb content greater than 10 ppm presented a consistent Pb isotopic distribution,whereas all the sulfide grains with Pb content greater than 100 ppm had consistent Pb isotopic composition within 2s measurement uncertainties.The in-situ analysis of Pb isotopic composition agreed well with the results obtained by conventional chemical methods within2s measurement uncertainties,indicating that the data obtained by fs LA-MC-ICP-MS are reliable.Additionally,this study indicates that the Pb isotopic composition could truthfully record the source of ore-forming minerals only for sulfide minerals with high Pb content.On the contrary,the Pb isotopic composition of low-Pb sulfide minerals may be affected by trace amounts of U in the host minerals that may lead to a highly radiogenic Pb isotope ratio.Alternatively,it is also possible that late fluid metasomatic overprinting may alter the Pb isotopic compositions. | YUAN HongLin YIN Cong LIU Xu CHEN KaiYun BAO ZhiAn ZONG ChunLei DAI MenNing LAI ShaoCong WANG Rong JIANG ShaoYong | 2015 | Science China Earth Sciences2015,58,10: | 14 |
| 8 | Potential key technologies for 6G mobile communications显示文摘The standard development of 5G wireless communication culminated between 2017 and 2019,followed by the worldwide deployment of 5G networks,which is expected to result in very high data rate for enhanced mobile broadband,support ultrareliable and low-latency services and accommodate massive number of connections.Research attention is shifting to future generation of wireless communications,for instance,beyond 5G or 6G.Unlike previous studies,which discussed the use cases,deployment scenarios,or new network architectures of 6G in depth,this paper focuses on a few potential technologies for 6G wireless communications,all of which represent certain fundamental breakthrough at the physical layer—technical hardcore of any new generation of wireless communications.Some of them,such as holographic radio,terahertz communication,large intelligent surface,and orbital angular momentum,are of revolutionary nature and many related studies are still at their scientific exploration stage.Several technical areas,such as advanced channel coding/modulation,visible light communication,and advanced duplex,while having been studied,may find more opportunities in 6 G. | Yifei YUAN Yajun ZHAO Baiqing ZONG Sergio PAROLARI | 2020 | Science China(Information Sciences)2020,63,8: | 13 |

| 10 | Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders. | XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu | 2015 | Science China(Life Sciences)2015,58,9: | 12 |
| 11 | Fast acceleration of “killer” electrons and energetic ions by interplanetary shock stimulated ULF waves in the inner magnetosphere显示文摘Energetic electrons and ions in the Van Allen radiation belt are the number one space weather threat. Understanding how these energetic particles are accelerated within the Van Allen radiation belt is one of the major challenges in space physics. This paper reviews the recent progress on the fast acceleration of 'killer' electrons and energetic ions by ultralow frequency (ULF) waves stimulated by the interplanetary shock in the inner magnetosphere. Very low frequency (VLF) wave-particle interaction is considered to be one of the primary electron acceleration mechanisms because electron cyclotron resonances can easily occur in the VLF frequency range. Recently, using four Cluster spacecraft observations, we have found that, after interplanetary shocks impact the Earth’s magnetosphere, energetic electrons in the radiation belt are accelerated almost immediately and continue to accelerate for a few hours. The time scale (a few days) for traditional acceleration mechanisms, based on VLF wave-particle interactions to accelerate electrons to relativistic energies, is too long to explain our observations. Furthermore, we have found that interplanetary shocks or solar wind pressure pulses, with even small dynamic pressure changes, can play a non-negligible role in radiation belt dynamics. Interplanetary shocks interaction with the Earth’s magnetosphere manifests many fundamental space physics phenomena including energetic particle acceleration. The mechanism of fast acceleration of energetic electrons in the radiation belt responding to interplanetary shock impacts consists of three contributing parts: (1) the initial adiabatic acceleration due to strong shock-related magnetic field compression; (2) followed by the drift-resonant acceleration with poloidal ULF waves excited at different L-shells; and (3) particle acceleration due to the quickly damping electric fields associated with ULF waves. Particles end up with a net acceleration because they gain more energy in the first half of this cycle than they lose in the second. The results reported in this paper cast a new light on understanding the acceleration of energetic particles in the Earth’s Van Allen radiation belt. The results of this study can likewise be applied to interplanetary shock interaction with other planets such as Mercury, Jupiter, Saturn, Uranus and Neptune, and other astrophysical objects with magnetic fields. | ZONG QiuGang WANG YongFu YUAN ChongJing YANG Biao WANG ChenRui ZHANG XiangYun | 2011 | Chinese Science Bulletin2011,56,12: | 11 |
| 12 | Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders:executive summary and 2019 update of the management of high-risk population显示文摘Aim Cerebrovascular disease is the leading cause of death and disability in China,causing a huge burden among patients and their families.Hence,stroke prevention is critical,especially in the high-risk population.Here,we present the evidence-based guideline suitable for the Chinese population.Methods Literature search of PubMed and Cochrane library(from January 1964 to June 2019)was done.After thorough discussion among the writing group members,recommendations were listed and summarised.This guideline was reviewed and discussed by the fellow writing committees of the Chinese Stroke Association’s Stroke.Results This evidence-based guideline was written in three parts:controlling the risk factors of stroke,utilisation of antiplatelet agents and assessing the risks of first-ever stroke.All recommendations were listed along with the recommending classes and levels of evidence.Conclusions This guideline provides recommendations for primary prevention of cerebrovascular disease among high-risk population in China.Controlling related risk factors,appropriately using antiplatelet agents,assessing the risk of developing first-ever stroke should help reduce the rate of cerebrovascular disease in China. | Yilong Wang Shangrong Han Haiqiang Qin Huaguang Zheng Bin Jiang Yong Cao Yuan Gao Ling Guan Qian Jia Yong Jiang Yuming Jiao Shuya Li Yapeng Li Zixiao Li Wei Liu Xiaojuan Ru Dongling Sun Haixin Sun Penglian Wang Tingting Wang Lixia Zong Lei Guo Xuewei Xie Yuming Xu Yuyuan Xu Xiaomeng Yang Yingying Yang Mengyuan Zhou Wenzhi Wang Chinese Stroke Association Stroke Council Guideline Writing Committee | 2020 | Stroke & Vascular Neurology2020,5,3: | 11 |
| 13 | Oxidative Stress and Apoptotic Changes of Rat Cerebral Cortical Neurons Exposed to Cadmium in Vitro显示文摘Objective To investigate the cytotoxic mechanism of cadmium(Cd) on cerebral cortical neurons.Methods The primary cultures of rat cerebral cortical neurons were treated with different concentrations of cadmium acetate(0,5,10,and 20 μmol/L),and then the cell viability,apoptosis,ultrastructure,intracellular [Ca2+]i and reactive oxygen species(ROS) levels,mitochondrial membrane potential(ΔΨ),activities of catalase(CAT) and superoxide dismutase(SOD) were measured.Results A progressive loss in cell viability and an increased number of apoptotic cells were observed.In addition,Cd-induced apoptotic morphological changes in cerebral cortical neurons were also demonstrated by Hoechst 33258 staining.Meanwhile,ultrastructural changes were distortion of mitochondrial cristae and an unusual arrangement.Simultaneously,elevation of intracellular [Ca2+]i and ROS levels,depletion of ΔΨ were revealed in a dose-dependent manner during the exposure.Moreover,CAT and SOD activities in the living cells increased significantly.Conclusion Exposure of cortical neurons to different doses of Cd led to cellular death,mediated by an apoptotic mechanism,and the apoptotic death induced by oxidative stress may be a potential reason.And the disorder of intracellular homeostasis caused by oxidative stress and mitochondrial dysfunction may be a trigger for apoptosis in cortical neurons. | YUAN Yan BIAN Jian Chun LIU Xue Zhong ZHANG Ying SUN Ya LIU Zong Ping | 2012 | Biomedical and Environmental Sciences2012,25,2: | 10 |
| 14 | Use of Xinfeng capsule to treat abarticular pathologic changes in patients with rheumatoid arthritis显示文摘OBJECTIVE: To observe the influence of Xinfengcapsule(XFC) on abarticular pathologic changes(APCs) and other indices of patients with rheumatoid arthritis(RA) and explore the mechanism of action of XFC in improving such changes.METHODS: Three-hundred RA patients were divided randomly into a treatment group(n=150) and control group(n=150). A normal control(NC)group(n=90) was also created. Changes in cardiac function, pulmonary function, anemia indices and platelet parameters of RA patients were measured.Curative effects of the two groups were compared,and comparison carried out with the NC group.RESULTS: In 300 RA patients, late diastolic peak flow velocity(A peak) was much higher(P<0.01)and early diastolic peak flow velocity(E peak), E/A,and left ventricular fraction shortening much lower(P<0.01) than those in the NC group. Vital capacity(VC), forced vital capacity in one second, forced vital capacity(FVC), maximal voluntary ventilation(MVV), maximal expiratory flow in 50% of VC(FEF50) and FEF75 were lowered remarkably(P<0.05 or P<0.01). Platelet count(PLT), plateletcrit(PCT) and mean platelet volume(MPV) increased markedly(P<0.05 or P<0.01), and hemoglobin(Hb)level decreased significantly(P<0.05). After XFC treatment, the A peak and PLT and PCT were much lower(P<0.05), and E/A and the number of red blood cells as well as Hb level were much higher(P<0.05), as were FVC, MVV and FEF50(P<0.05 or P<0.01), in the treatment group than those in the NC group. Total score of pain and swelling in joints,uric-acid level and high-sensitivity C-reactive protein level were much lower, and superoxide dismutase level as well as the number of CD4 +CD25+ regulation T cells(Treg) and CD4+CD25+CD127- Treg were much higher(P<0.05 or P<0.01)in the treatment group than those in the NC group.CONCLUSION: RA patients with pathologic changes in joints also suffer from lower cardiac and pulmonary functions and from parameters of anemia and platelet factors. XFC can improve the symptoms of RA patients, ameliorate their cardiac and pulmonary functions and reduce the parameters of anemia and platelet factors. XFC lowers the immune inflammatory reaction to improve APCs in RA patients. | Jian Liu Yunxiang Cao Chuanbing Huang Yuan Wang Xi Chen Wandong Zhang Guizhen Wang Haixia Fan Yao Ge Ruilian Chen Ruikai Zong Yajun Qi Yue Sun Yifei Liu Fang Wang | 2014 | Journal of Traditional Chinese Medicine2014,34,5: | 10 |
| 15 | Dynamic variations of the outer radiation belt during magnetic storms for 1.5–6.0 MeV electrons显示文摘The CME’s structure of solar wind(interplanetary magnetic field)is different from CIR’s.The two processes in which plasma and solar wind energy are injected into the Earth’s inner magnetosphere are not the same.So,the variations of energetic elec- trons flux in the radiation belts are different between the storms associated with CMEs and CIRs.By using data from SAMPEX(Solar,Anomalous,and Magnetospheric Particle Explorer)satellite,we have investigated the dynamic variations of the outer radiation belt for 1.5–6.0 MeV electrons during 54 CME-driven storms and 26 CIR-driven recurrent storms.According to the superposed epoch analysis,for CME-and CIR-driven storms,when the Dst index reaches the minimum,the locations of the outer boundary move to L=4 and L=5.5,respectively.In the recovery phases,the locations of the outer boundary of the outer radiation belt are generally lower than and slightly higher than those before CME-and CIR-driven storms,respectively.We have found that the logarithmically decaying 1/e cut-off L-shell is a satisfying indicator of the outer boundary of the outer radiation belt.Furthermore,our study shows that the logarithmically decaying 1/e cut-off latitude is dependent on the Kp index in the main phases of CME-and CIR-driven storms,while in the recovery phases,there is no obvious correlation.In ad- dition,it has been shown that the locations of the peak electron flux are controlled by the minimum Dst index in the main phases of CME-driven storms.The influences of multiple storms on the electron flux of outer radiation belt have also been in- vestigated. | YUAN ChongJing ZONG QiuGang | 2011 | Science China(Technological Sciences)2011,54,2: | 9 |
| 16 | Expert consensus on the glycemic management of critically ill patients显示文摘Introduction The incidence of hyperglycemia is 40-60%in critically ill patients and is up to 60-80%in those who have undergone car-diac surgery.[1]The results of an epidemiological study in the United States showed that 28.6%of diabetic patients and 9.3%of non-diabetic patients had elevated mean daily glucose on the day of ICU admission.[2]In critically ill patients,elevated blood glucose is primarily the result of stress,and stress-induced hy-perglycemia is an independent risk factor associated with prog-nosis,regardless of a previous diagnosis of diabetes.Nutritional therapy has become an integral treatment option for patients in the ICU,[3,4]though nearly 30%of patients with enteral nu-trition and 44-50%with parenteral nutrition(PN)experience elevated glucose.[5,6]Intensive insulin therapy(IIT)is an impor-tant treatment for controlling hyperglycemia in critically ill pa-tients,but it also carries a corresponding risk of hypoglycemia. | Zhixiong Wu Jiao Liu Dong Zhang Kai Kang Xiangrong Zuo Qianghong Xu Aijun Pan Wei Fang Fen Liu You Shang Haiyan Yin Juntao Hu Jinglun Liu Jiangquan Fu Wei Zhang Yuan Zong Min Shao Feng Zhao Mei Meng Yanfei Mao Yingchuan Li Dechang Chen | 2022 | Journal of Intensive Medicine2022,2,3: | 9 |
| 17 | Development of genome-wide insertion/deletion markers in rice based on graphic pipeline platform显示文摘DNA markers play important roles in plant breeding and genetics.The Insertion/Deletion(InDel) marker is one kind of co-dominant DNA markers widely used due to its low cost and high precision.However,the canonical way of searching for InDel markers is time-consuming and laborintensive.We developed an end-to-end computational solution(InDel Markers Development Platform,IMDP) to identify genome-wide InDel markers under a graphic pipeline environment.IMDP constitutes assembled genome sequences alignment pipeline(AGA-pipe) and next-generation resequencing data mapping pipeline(NGS-pipe).With AGA-pipe we are able to identify 12,944 markers between the genome of rice cultivars Nipponbare and 93-11.Using NGS-pipe,we reported 34,794 InDels from re-sequencing data of rice cultivars Wu-Yun-Geng7 and Guang-Lu-Ai4.Combining AGApipe and NGS-pipe,we developed 205,659 InDels in eight japonica and nine indica cultivars and 2,681 InDels showed a subgroup-specific pattern.Polymerase chain reaction(PCR)analysis of subgroup-specific markers indicated that the precision reached 90%(86 of 95).Finally,to make them available to the public,we have integrated the InDels/markers information into a website(Rice InDel Marker Database,RIMD,http://202.120.45.71/).The application of IMDP in rice will facilitate efficiency for development of genome-wide InDel markers,in addition it can be used in other species with reference genome sequences and NGS data. | Yang L Xiao Cui Rui Li Piaopiao Huang Jie Zong Danqing Yao Gang Li Dabing Zhang Zheng Yuan | 2015 | Journal of Integrative Plant Biology2015,57,11: | 9 |

| 19 | Cadmium Activates Reactive Oxygen Species-dependent AKT/mT OR and Mitochondrial Apoptotic Pathways in Neuronal Cells显示文摘Objective To examine the role of Cd-induced reactive oxygen species(ROS)generation in the apoptosis of neuronal cells.Methods Neuronal cells(primary rat cerebral cortical neurons and PC12 cells)were incubated with or without Cd post-pretreatment with rapamycin(Rap)or N-acetyl-L-cysteine(NAC).Cell viability was determined by MTT assay,apoptosis was examined using flow cytometry and fluorescence microscopy,and the activation of phosphoinositide 3'-kinase/protein kinase B(Akt)/mammalian target of rapamycin(m TOR)and mitochondrial apoptotic pathways were measured by western blotting or immunofluorescence assays.Results Cd-induced activation of Akt/m TOR signaling,including Akt,m TOR,p70 S6 kinase(p70 S6K),and eukaryotic initiation factor 4E binding protein 1(4E-BP1).Rap,an m TOR inhibitor and NAC,a ROS scavenger,blocked Cd-induced activation of Akt/m TOR signaling and apoptosis of neuronal cells.Furthermore,NAC blocked the decrease of B-cell lymphoma 2/Bcl-2 associated X protein(Bcl-2/Bax)ratio,release of cytochrome c,cleavage of caspase-3 and poly(ADP-ribose)polymerase(PARP),and nuclear translocation of apoptosis-inducing factor(AIF)and endonuclease G(Endo G).Conclusion Cd-induced ROS generation activates Akt/m TOR and mitochondrial pathways,leading to apoptosis of neuronal cells.Our findings suggest that m TOR inhibitors or antioxidants have potential for preventing Cd-induced neurodegenerative diseases. | YUAN Yan WANG Yi HU Fei Fei JIANG Chen Yang ZHANG Ya Jing YANG Jin Long ZHAO Shi Wen GU Jian Hong LIU Xue Zhong BIAN Jian Chun LIU Zong Ping | 2016 | Biomedical and Environmental Sciences2016,29,2: | 8 |
| 20 | Radial propagation of magnetospheric substorm-injected energetic electrons observed using a BD-IES instrument and Van Allen Probes显示文摘In cases where substorm injections can be observed simultaneously by multiple spacecraft,they can help elucidate the potential mechanisms of particle transport and energization,of great importance to understanding and modeling the magnetosphere.In this paper,using data returned from the BeiDa-IES(BD-IES) instrument onboard a satellite in an inclined(55°) geosynchronous orbit(IGSO),in combination with two geo-transfer orbiting(GTO) satellite Van Allen Probes(A and B),we analyze a substorm injection event that occurred on the 16 th of October 2015.During this substorm injection,the IGSO onboard BD-IES was outbound,while both Van Allen Probe satellites(A and B) were inbound,a configuration of multiple trajectories that provides a unique opportunity to simultaneously investigate both the inward and outward radial propagation of substorm injection.Indicated by AE/AL indices,this substorm was closely related to an IMF/solar wind discontinuity that showed a sharp change in IMF Bz direction to the north.The innermost signature of this substorm injection was detected by Van Allen Probes A and B at L-3.7,while the outermost signature was observed by the onboard BD-IES instrument at L~\0.These data indicate that the substorm had a global,rather than just local,effect.Finally,we suggest that electric fields carried by fast-mode compressional waves around the substorm injection are the most likely candidate mechanism for the electron injection signatures observed in the inner- and outermost inner magnetosphere. | ZONG QiuGang HAO YiXin ZOU Hong FU SuiYan ZHOU XuZhi REN Jie WANG LingHua YUAN ChongJing LIU ZhiYang JIA XiangHong QUAN Lin LIU Ying WANG YongFu | 2016 | Science China Earth Sciences2016,59,7: | 8 |
