1Microbialite of anoxic condition from Permian-Triassic transition in Guizhou,China显示文摘Spherical microfossils are present in the Hindeodus parvus zone of the Lower Triassic in Ziyun,Guizhou Province. They generally range from 0.15 to 0.30 mm across,with micritic wall and filled by micro-sparry calcites,and are evenly scattered in micritic matrix. Their abundance makes the rock as-signed to microbialites. The accompanied organisms include ostracods and algal mat,but no gastro-pods or bivalves. Presence of small (<7 μm) pyrite framboids indicates that this bed formed in anoxic conditions. In some sections,this bed is overlain and underlain by tidal-flat micritic limestone with microgastropods and small burrows. Occurrence only in deposits on reef top indicates that the micro-bial organism was benthic,and needed sunlight in life. The size of the microbial fossil exceeds that of any bacteria or cyanobacteria. Thus,it does not belong to these two phyla. It may belong to lower green algae,and is assigned to a new species in a new genus,Ziyunosphaeridium sinensis gen. et sp. nov. Up to now,the rocks described as microbialites from the Permian-Triassic transition include six types: (1) porous micritic limestone such as that descried from Japan by Sano and Nakashima (1997),(2) limestone with rich globular microfossils such as that described from the Nanpanjiang Basin in China by Lehrmann (1999),(3) dendroidal limestone such as that described from the vicinity of Chongqing by Kershaw et al. (1999),(4) spherical microbial limestone adapted to anoxic environments described from Ziyun,Guizhou reported in this paper,(5) limestone with cyanobacterial fossils such as that described by Wang et al. (2005),and (6) stromatolites. All these microbialites are not reefs in the proper sense,and the argument that Permian reef ecosystems extended into the Mesozoic is incorrect.WU YaSheng JIANG HongXia YANG Wan FAN JiaSong 2007Science China Earth Sciences2007,50,7:18

4Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation.Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu 2019Cancer Biology & Medicine2019,16,1:14
5Extinction pattern of reef ecosystems in latest Permian显示文摘Studies of two Permian-Triassic boundary (PTB) sections on top of a Changhsingian reef in Ziyun, Guizhou Province, southwestern China indicate that the end-Permian mass extinction of reef ecosystems occurred in two steps. The first step is the extinction of all stenotropic organisms such as calcisponges and fusulinids in the latest Permian (in the Clarkina yini conodont zone). The biota after the first extinction is simple, comprising eurytropic organisms including microgastropods, ostracods, and some small burrowing organisms, or only algal mats. At the beginning of the Early Triassic (i.e. the beginning of the Hindeodus parvus zone), the environments became anoxic, and the microgastropod dominated biota or algal mats disappeared, which constituted the second episode of the mass extinction. The biota after the second extinction comprises small spherical microproblematica, some kinds of specialized organisms tolerant of anoxic or oxygen-poor conditions. As the environments became oxygenated, the specialized biota was replaced by a microgastropod-dominated simple biota. When the environmental conditions improved further, the simple biota was replaced by a diverse biota with normal-sized ammonoids, bivalves, and gastropods, representing restoration of normal oceanic condi- tions. Comparison with PTB sections in Dolomites, Italy and Meishan, Zhejiang Province shows that non-reef ecosystems had a similar first episode of mass extinction in the latest Permian. In the case that oceanic anoxia happened, non-reef ecosystems had a second extinction episode similar to that of reef ecosystems.WU YaSheng FAN JiaSong JIANG HongXia YANG Wan 2007Chinese Science Bulletin2007,52,4:11
6Secretory/releasing proteome-based identification of plasma biomarkers in HBV-associated hepatocellular carcinoma显示文摘For successful therapy, hepatocellular carcinoma (HCC) must be detected at an early stage. Herein, we used a proteomic approach to analyze the secretory/releasing proteome of HCC tissues to identify plasma biomarkers. Serum-free conditioned media (CM) were collected from primary cultures of cancerous tissues and surrounding noncancerous tissues. Proteomic analysis of the CM proteins permitted the identification of 1365 proteins. The enriched molecular functions and biological processes of the CM proteins, such as hydrolase activity and catabolic processes, were consistent with the liver being the most important metabolic organ. Moreover, 19% of the proteins were characterized as extracellular or membrane-bound. For validation, secretory proteins involved in transforming growth factor-β signaling pathways were validated in plasma samples. Alphafetoprotein (AFP), metalloproteinase (MMP)1, osteopontin (OPN), and pregnancy-specific beta-1-glycoprotein (PSG)9 were significantly increased in HCC patients. The overall performance of MMP1 and OPN in the diagnosis of HCC remained greater than that of AFP. In addition, this study represents the first report of MMP1 as a biomarker with a higher sensitivity and specificity than AFP. Thus, this study provides a valuable resource of the HCC secretome with the potential to investigate serological biomarkers. MMP1 and OPN could be used as novel biomarkers for the early detection of HCC and to improve the sensitivity of biomarkers compared with AFP.YANG Lei RONG WeiQi XIAO Ting ZHANG Ying XU Bin LIU Yu WANG LiMing WU Fan QI Jun ZHAO XiuYing WANG HongXia HAN NaiJun GUO SuPing WU JianXiong GAO YanNing CHENG ShuJun 2013Science China(Life Sciences)2013,56,7:9

8Matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 expression in early focal cerebral infarction following urokinase thrombolysis in rats显示文摘Activity of matrix metalloproteinase-9 increases following cerebral ischemia/reperfusion,and is associated with cerebral microvascular permeability,blood-brain barrier destruction,inflammatory cell infiltration and brain edema.Matrix metalloproteinase-9 also likely participates in thrombolysis.A rat model of middle cerebral artery infarction was established by injecting autologous blood clots into the internal carotid artery.At 3 hours following model induction,urokinase was injected into the caudal vein.Decreased neurological severity score,reduced infarct volume,and increased expression of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 were observed in the cerebral cortex 24 hours after urokinase thrombolysis.These results suggest that urokinase can suppress damage in the acute-early stage of cerebral infarction.Yuqiang Song Hongli Zou Guofeng Wang Hongxia Yang Zhaohong Xie Jianzhong Bi 2012Neural Regeneration Research2012,7,17:6

11Recent advancements in metal-organic frameworks for green applications显示文摘A series of environmental and energy issues,such as global warming,water pollution,acid rain,and energy shortage,have to be settled urgently.Metal-organic frameworks(MOFs)are compounds consisting of metal ions or clusters coordinated to organic ligands,which show great promise for alleviating or mitigating these challenges owing to their outstanding physical and chemical properties.In this review,we summarize the recent advances of MOFs in the fields of green applications,including carbon capture,harmful gas removal,sewage treatment,and green energy storage.In addition,the challenges and prospects of the large-scale commercialized use of MOFs in handling environmental issues are also discussed.Chongxiong Duan Yi Yu Jing Xiao Yuanyuan Li Pengfei Yang Fei Hu Hongxia Xi 2021Green Energy & Environment2021,6,1:6
12Hot deformation behavior and workability characteristic of a fine-grained Mg–8Sn–2Zn–2Al alloy with processing map显示文摘The hot deformation behavior of a fine-grained Mg–8 Sn–2 Zn–2 Al(TZA822, in wt%) alloy was investigated in the temperature range of 150–350°C and the strain rate of 0.01–10 s^-1 employing thermomechanical simulator. In most of the cases, the material showed typical dynamic recrystallization(DRX) features i.e., a signal peak value followed by a gradual decrease or to reach a steady state. The work hardening rate was found to increase with decreasing temperature and increasing strain rate, while strain rates had great effects on work hardening behavior. Meanwhile, the constitutive analysis indicated that cross-slip of dislocations was likely to be the dominant deformation mechanism. In addition, the processing map at the strain of 0.1–0.7 showed two stability domains with high power dissipation efficiencies and the optimum hot working parameters for the studied alloy was determined to be 350°C/0.01 s^-1 and 350°C/10 s^-1, at which continuous DRX(CDRX) and discontinuous DRX(DDRX) as main softening mechanism. The instability regions occurred at 200–250°C/10 s^-1 and the main flow instability mechanism was twinning and/or flow localization bands, which were prone to induce cracks and caused in-consistent mechanical properties of the alloy.Weili Cheng Yang Bai Shichao Ma Lifei Wang Hongxia Wang Hui Yu 2019Journal of Materials Science & Technology2019,35,6:5
13Breast cancer-specific serum peptide profiles显示文摘Early detection of breast cancer is paramount to successful clinical therapy. Yet, early-stage breast cancer lacks specific symptoms or biomarkers. With the emerging of the mass spectrometric (MS) -based signatures as biomarkers, we investigated breast cancer-related serum profile pattern through class prediction and independent validation, and used Fourier transfer MS to identify breast cancer signature. We now show a distinctive serum peptide pattern that discriminates breast cancer from healthy controls with 93.2% sensitivity and 95.4% specificity. m/z 5901.70 and 4465.74 of ion fragment of FPA and alpha1-antichymotrypsin are found in the signatures that predominantly discriminate breast cancer from healthy individuals. These novel findings identify an MS-based serum peptide pattern of breast cancer that may have direct clinical utility in future.WANG Na WEN XinYu WANG Jie LI AiLing LI WeiHua LI Tao Li Yan ZHANG XueMin WANG HongXia YANG SongCheng ZHOU Tao GONG WeiLi TIAN YaPing HE Kun 2009Chinese Science Bulletin2009,54,3:4

15Effect of Jianpiyiqi granule on ocular myasthenia gravis in children prepared with a formula from Traditional Chinese Medicine显示文摘OBJECTIVE: To investigate the effect of Jianpiyiqi granule, prepared according to a Traditional Chinese Medicine(TCM) formula, on the ocular type of myasthenia gravis(MG) caused by a defect in synaptic transmission at the neuromuscular junction.METHODS: A total of 155 children with ocular MG were recruited from January 2008 to January 2015.All individuals received ineffective glucocorticoid treatment prior to admission, and were given Jianpiyiqi granules(two doses per day) for 12 months.Plasma levels of acetylcholine receptor autoantibodies(ACh R-Ab), cytokines, immune parameters and clinical score were analyzed.RESULTS: After intervention with Jianpiyiqi granule for 12 months, the levels of cytokines [including interleukin(IL)-6, IL-12, IL-17], immune parameters[including immunoglobulin G(Ig G), Ig M, free triiodothyronine, free thyroxine] and ACh R-Ab were sig-nificantly decreased(P = 0.042, P = 0.049, P = 0.011,P = 0.02, P = 0.04, P = 0.03, P = 0.01; F = 21.60, P =0.000). In contrast, IL-4 levels were significantly increased(P = 0.049). The absolute clinical score after treatment declined significantly compared with before treatment(F = 33.24, P = 0.000). The effective cure rate and the total effective rate gradually increased to a maximum of 149(96.2%) and 151(97.4%) in MG patients after 12 months of treatment, respectively.CONCLUSION: The Jianpiyiqi granule treatment lowered ACh R-Ab levels and improved cytokine and other immune parameter levels, which suggests that the granule could be an ancillary treatment for ocular MG in children caused by a defect in synaptic transmission at the neuromuscular junction.Qi Guoyan Liu Peng Gu Shanshan Yang Hongxia Dong Huimin Xue Yinping 2017Journal of Traditional Chinese Medicine2017,37,4:4
16A novel ESD power supply clamp circuit with double pull-down paths显示文摘Electrostatic-discharge(ESD)protection design is one of the key challenges of advanced CMOS processes.RC-triggered and MOSFET-based power supply ESD clamp circuits have been widely used to obtain the desired ESD protection ability.In this paper,a MOSFET-based ESD power clamp circuit with only10 ns RC time constant for 0.18-μm process is presented.A double pull-down path is proposed to avoid false triggering,reject power supply noise and reduce energy consumption.The performance of the novel clamp circuit is excellent,consuming very small layout area.The simulation results show that this clamp circuit can be used in industry.LIU HongXia YANG ZhaoNian LI Li ZHUO QingQing 2013Science China(Information Sciences)2013,56,10:4
17CD146 as a promising therapeutic target for retinal and choroidal neovascularization diseases显示文摘Blood vessel dysfunction causes several retinal diseases,including diabetic retinopathy,familial exudative vitreoretinopathy,macular degeneration and choroidal neovascularization in pathological myopia.Vascular endothelial growth factor(VEGF)-neutralizing proteins provide benefits in most of those diseases,yet unsolved haemorrhage and frequent intraocular injections still bothered patients.Here,we identified endothelial CD146 as a new target for retinal diseases.CD146 expression was activated in two ocular pathological angiogenesis models,a laser-induced choroid neovascularization model and an oxygeninduced retinopathy model.The absence of CD146 impaired hypoxia-induced cell migration and angiogenesis both in cell lines and animal model.Preventive or therapeutic treatment with anti-CD146 antibody AA98 significantly inhibited hypoxia-induced aberrant retinal angiogenesis in two retinal disease models.Mechanistically,under hypoxia condition,CD146 was involved in the activation of NFκB,Erk and Akt signalling pathways,which are partially independent of VEGF.Consistently,anti-CD146therapy combined with anti-VEGF therapy showed enhanced impairment effect of hypoxia-induced angiogenesis in vitro and in vivo.Given the critical role of abnormal angiogenesis in retinal and choroidal diseases,our results provide novel insights into combinatorial therapy for neovascular fundus diseases.Bai Xue Ping Wang Wenzhen Yu Jing Feng Jie Li Rulian Zhao Zhenglin Yang Xiyun Yan Hongxia Duan 2022Science China(Life Sciences)2022,65,6:3
18Three-Dimensional Quantitative Structure-Activity Relationships of flavonoids and estrogen receptors based on docking显示文摘Flavonoids are endocrine disrupting compounds that occur ubiquitously in foods of plant origin.The Three-Dimensional Quantitative Structure-Activity Relationships (3D-QSAR) model based on ligand-receptor docking is established between 20 flavonoids and estrogen receptor alpha (ERα),which may provide further theoretical basis for research on the relationship between flavones and estrogen.Comparative molecular field analysis (CoMFA) was employed and the best results of cross-validation and non cross validation were 0.845 and 0.988,respectively.Correspondingly,molecular similarity index analysis (CoMSIA) was employed and the results of cross-validation and non cross validation were 0.670 and 0.990,respectively.The CoMFA/CoMSIA and docking results reveal the structural features for estrogen activity and key amino acid residues in binding pocket,and provide an insight into the interaction between the ligands and these amino acid residues.WU Yang WANG Yong ZHANG AiQian YU HongXia WANG LianSheng 2010Chinese Science Bulletin2010,55,15:3
19Hypoxia-controlled matrix metalloproteinase-9 hyperexpression promotes behavioral recovery after ischemia显示文摘Matrix metalloproteinase-9(MMP-9) plays a beneficial role in the sub-acute phase after ischemic stroke.However,unrestrained MMP-9 may disrupt the blood-brain barrier(BBB),which has limited its use for the treatment of brain ischemia.In the present study,we constructed lentivirus mediated hypoxiacontrolled MMP-9 expression and explored its role after stroke.Hypoxia response element(HRE)was used to confine MMP-9 expression only to the hypoxic region of mouse brain after 120-min transient middle cerebral artery occlusion.Lentiviruses were injected into the peri-infarct area on day 7 after transient ischemia.We found hyperexpression of exogenous HRE-MMP-9 under the control of hypoxia,and its expression was mainly located in neurons and astrocytes without aggravation of BBB damage compared to the CMV group.Furthermore,mice in the HRE-MMP-9 group showed the best behavioral recovery compared with the normal saline,GFP,and SB-3CT groups.Therefore,hypoxia-controlled MMP-9 hyperexpression during the sub-acute phase of ischemia may provide a novel promising approach of gene therapy for stroke.Hongxia Cai Zhihao Mu Zhen Jiang Yongting Wang Guo-Yuan Yang Zhijun Zhang 2015Neuroscience Bulletin2015,31,5:3
20Low leakage 3×VDD-tolerant ESD detection circuit without deep N-well in a standard 90-nm low-voltage CMOS process显示文摘A new low leakage 3×VDD-tolerant electrostatic discharge(ESD)detection circuit using only low-voltage device without deep N-well is proposed in a standard 90-nm 1.2-V CMOS process.Stacked-transistors technique is adopted to sustain high-voltage stress and reduce leakage current.No NMOSFET operates in high voltage range and it is unnecessary to use any deep N-well.The proposed detection circuit can generate a 38 mA current to turn on the substrate triggered silicon-controlled rectifier(STSCR)under the ESD stress.Under normal operating conditions,all the devices are free from over-stress voltage threat.The leakage current is 88 nA under 3×VDD bias at 25°C.The simulation result shows the circuit can be successfully used for 3×VDD-tolerant I/O buffer.YANG ZhaoNian LIU HongXia WANG ShuLong 2013Science China(Technological Sciences)2013,56,8:3
