| 1 | Ages, Trace Elements and Hf-Isotopic Compositions of Zircons from Claystones around the Permian-Triassic Boundary in the Zunyi Section, South China: Implications for Nature and Tectonic Setting of the Volcanism显示文摘证据的成长身体证明二叠三叠纪的边界(PTB ) 附近的那个火山作用可能在触发 PermianTriassic (PTr ) 是关键的集体扑灭。因此,在华南的 PTB 附近的灰床可以在这个事件上带信息。三暴烈的灰层,改变了到泥土,在在 Zunyi 节的 PTB 床上的 outcropped,贵州省,西南中国。从这三张灰床的锆石谷物的 U-Pb 年龄,踪迹元素,和 Hf 同位素作文用 LA-ICPMS 和 LA-MC-ICPMS 被分析。锆石主要除了二 inherited/xenocrystic 锆石(939 和 2 325 妈) 是在起源(241-279 妈) 的 magmatic。这些 magmatic 锆石的年龄显示发生在中间附近的 magmatism 的三个事件 -- 晚二叠的边界(~ 261.5 妈, MLPB ) , Wuchiapingian-Changhsingian 边界(~ 254.5 妈, WCB ) ,并且 PTB (~ 250.5 妈) 分别地。MLPB 和 WCB 附近的 magmatism 的开始的二个事件可以被归因于 magmatic 继承或重新免职。所有 magmatic 锆石分享类似的踪迹元素和 Hf 同位素作文。他们有 Y, Hf, Th 和 U 内容和 Nb/Ta 比率典型地代表从硅的计算碱的岩浆的锆石。这些锆石也与 -11.4 的 Hf (t) 价值展出充实的 Hf 同位素作文到 +0.2,它建议三个 magmatic 事件涉及大陆人外壳融化。更多的充实的 Hf 同位素作文(床 ZY13 的 Hf (t)=-11.4--4.8)(~ 250.5 妈) 在岩浆暗示古老的外壳的材料的更多的输入。magmatic 锆石的 Hf 同位素和踪迹元素作文的集成建议 magmatism 的这三个事件可以由于 Palaeo-Tethys 海洋的闭合沿着会聚的大陆边缘发生在或在西南的华南附近。 | Qiuling Gao Zhong-Qiang Chen Ning Zhang William L.Griffin Wenchen Xia Guoqing Wang Tengfei Jiang Xuefei Xia Suzanne Y.O'Reilly | 2015 | Journal of Earth Science2015，26，6： | 8 |
| 2 | Reexamination of Radiolarian Biostratigraphy in Permian in Pelagic Chert Sequences at Dachongling Section, South China显示文摘Permian radiolarian biostratigraphy was reexamined in the bedded chert section in Qinzhou area of southeast Guangxi Zhuang Autonomous Region, South China. On the basis of the analyses of characteristic radiolarian composition, six radiolarian zones are recognized, namely, Pseudoalbaillella longtanensis Zone, Pseudoalbaillella globosa Zone, Follicucullus monacanthus Zone, Follicucullus scholasticus Zone, Follicucullus charveti Zone and Neoalbaillella ornithoformis Zone, in ascending order. Correlation of these radiolarian zones with those in Japan is presented. The Neoalbaillella ornithoformis Zone was firstly discovered in Dachongling Section, which may indicate that pelagic chert of the late Permian existed there, according to the co occurring conodonts. | Sun Dongying Xia Wenchen Liu Dongjie Faculty of Earth Sciences, China University of Geosciences, Wuhan 430074 | 2002 | Journal of China University of Geosciences2002，13，3： | 3 |
| 3 | Periostin mediates epithelial-mesenchymal transition through the MAPK/ERK pathway in hepatoblastoma显示文摘Objective: The aim of the present study was to analyze the prognostic factors in patients with hepatoblastoma(HB) in our single center and to evaluate periostin(POSTN) expression in HB and its association with clinicopathological variables. In addition, the underlying mechanism of how POSTN promotes HB progression was discussed.Methods: POSTN expression was investigated in HB tumors by immunohistochemistry(IHC), immunofluorescence(IF) and Western blot(WB). The association among POSTN expression, clinicopathological features and overall survival(OS) was also evaluated. The migration and adhesion ability of HB cells were measured using chemotaxis and cell-matrix adhesion assays,respectively. Epithelial-mesenchymal transition(EMT)-associated markers and activation of the ERK pathway were detected by WB.Results: HB patients had poor prognosis which displayed lymph node metastasis, vascular invasion, POSTN and vimentin expression. POSTN expression was also associated with lymph node metastasis. Furthermore, overexpressed POSTN promoted migration and the adhesive ability of HB cells in vitro. In addition, we demonstrated that POSTN activated the MAPK/ERK pathway, upregulated the expression of Snail and decreased the expression of OVOL2. Finally, POSTN promoted the expression of EMT-associated markers.Conclusions: POSTN might modulate EMT via the ERK signaling pathway, thereby promoting cellular migration and invasion.Our study also suggests that POSTN may serve as a therapeutic biomarker in HB patients. | Lu Chen Xiangdong Tian Wenchen Gong Bo Sun Guangtao Li Dongming Liu Piao Guo Yuchao He Ziye Chen Yuren Xia Tianqiang Song Hua Guo | 2019 | Cancer Biology & Medicine2019，16，1： | 3 |
| 4 | Characteristics of Albaillella (Albaillellarian,Radiolarian) Fauna from Guadalupian to Lopingian Series in Permian,South China显示文摘On the basis of establishment of radiolarian biostratigraphy and conodont biostratigraphy, a radiolarian Albaillella fauna in the transitional environment from Guadalupian to Lopingian Series in Permian was found at a pelagic chert section in southeast Guangxi, South China. Radiolarian Albaillella is one of the most sensitive biology to the transitional environment. The Albaillella fauna shows an ecological evolutionary process from Guadalupian to Lopingian: declined stage-recovery stage-flourishing stage. The study of characteristics of the Albaillella fauna in the transitional environment may provide more information, not only for the subdivision and correlation of a high-resolution biostratigraphy, but also for influence of radiolarian Albaillella fauna on the pre-Lopingian mass extinction. | Sun Dongying Xia Wenchen Faculty of Earth Sciences, China University of Geosciences, Wuhan 430074 | 2003 | Journal of China University of Geosciences2003，14，4： | 2 |
| 5 | Conodont Biostratigraphy across the Permian-Triassic Boundary at the Xinmin Section,Guizhou,South China显示文摘A continuous sedimentation at the Xinmin Section, Anshun, Guihzou Province, with the Upper Permian Talung Formation dominated by bedded siliceous rocks, and the Lower Triassic Luolou Formation consisting mudstones and marls as well as siliceous mudstones at its basal part indicates that it represents a deeper-water basinal facies across the Permian-Triassic boundary. Based on a systematic conodont biostratigraphic work, nine conodont species belong to two genera have been identified in this study. It enable us to establish five conodont zones at this section, in ascending order, they are: Clarkina changxingensis Zone(beds 1-3–4-2), Clarkina yini Zone(beds 4-3–5-1-1), Clarkina meishanensis Zone(beds 5-1-2–5-2), Hindeodus changxingensis Zone(beds 5-3-1–5-3-2) and Hindeodus parvus Zone(beds 5-3-3–5-3-4), respectively. According to the first occurrence of Hindeodus parvus in bed 5-3-3, the Permian-Triassic boundary is placed at the base of bed 5-3-3. This conodont zonation of the Xinmin Section provides precise biostratigraphic framework for further investigations on the geological events across the Permian-Triassic boundary at this section. In addition, the new conodont data also reveals that several siliceous beds occurred at the basal Triassic. It provides an exception of Early Triassic Chert Gap. | Ning Zhang Haishui Jiang Wenli Zhong Haohao Huang Wenchen Xia | 2014 | Journal of Earth Science2014，25，5： | 2 |

| 8 | Evolution of the Extensional Rifted Yunnan-Guizhou-Guangxi Oceanic Basin During the Late Hercynian to Middle Indosinian Stage显示文摘On the basis of exhaustive researches on the facies sequences and depositlonal evolutionary process of various depositional systems, the genetic stratigraphic framework of the extensional rifted oceanic basin, which has undergone strong structural destruction, has been reconstructed by means of dynamic genetic stratigraphic analysis. Five depositional episodes have been distinguished from various isochronous stratigraphic boundaries and stratigraphic sequences with the three-dimensional structure of each depositional episode analysed in detail. The tectonic paleogeographic environment corresponding to different stages of each depositional episode has been reconstructed for individual depositional system tracts. And the evolution history of this rifted basin has been divided into four stages’ initial rifting and oceanization of continental crust, stretching and spreading of the basin, subduction and basin differentiation, and convergence and collision.
