| 1 | Plate tectonic control on the formation and tectonic migration of Cenozoic basins in northern margin of the South China Sea显示文摘The tectonic evolution history of the South China Sea(SCS) is important for understanding the interaction between the Pacific Tectonic Domain and the Tethyan Tectonic Domain,as well as the regional tectonics and geodynamics during the multi-plate convergence in the Cenozoic.Several Cenozoic basins formed in the northern margin of the SCS,which preserve the sedimentary tectonic records of the opening of the SCS.Due to the spatial non-uniformity among different basins,a systematic study on the various basins in the northern margin of the SCS constituting the Northern Cenozoic Basin Group(NCBG) is essential.Here we present results from a detailed evaluation of the spatial-temporal migration of the boundary faults and primary unconformities to unravel the mechanism of formation of the NCBG.The NCBG is composed of the Beibu Gulf Basin(BBGB),Qiongdongnan Basin(QDNB),Pearl River Mouth Basin(PRMB) and Taixinan Basin(TXNB).Based on seismic profiles and gravity-magnetic anomalies,we confirm that the NE-striking onshore boundary faults propagated into the northern margin of the SCS.Combining the fault slip rate,fault combination and a comparison of the unconformities in different basins,we identify NE-striking rift composed of two-stage rifting events in the NCBG:an early-stage rifting(from the Paleocene to the Early Oligocene) and a late-stage rifting(from the Late Eocene to the beginning of the Miocene).Spatially only the late-stage faults occurs in the western part of the NCBG(the BBGB,the QDNB and the western PRMB),but the early-stage rifting is distributed in the whole NCBG.Temporally,the early-stage rifting can be subdivided into three phases which show an eastward migration,resulting in the same trend of the primary unconformities and peak faulting within the NCBG.The late-stage rifting is subdivided into two phases,which took place simultaneously in different basins.The first and second phase of the early-stage rifting is related to back-arc extension of the Pacific subduction retreat system.The third phase of the earlystage rifting resulted from the joint effect of slab-pull force due to southward subduction of the proto-SCS and the back-arc extension of the Pacific subduction retreat system.In addition,the first phase of the late-stage faulting corresponds with the combined effect of the post-collision extension along the Red River Fault and slab-pull force of the proto-SCS subduction.The second phase of the late-stage faulting fits well with the sinistral faulting of the Red River Fault in response to the Indochina Block escape tectonics and the slab-pull force of the proto-SCS. | Pengcheng Wang Sanzhong Li Yanhui Suo Lingli Guo Guangzeng Wang Gege Hui M.Santosh Ian D.Somerville Xianzhi Cao Yang Li | 2020 | Geoscience Frontiers2020，11，4： | 10 |
| 2 | Linkage between reactivation of the sinistral strike-slip faults and 28 September 2018 Mw7.5 Palu earthquake, Indonesia显示文摘On September 28, 2018, a Mw7.5 earthquake occurred near Sulawesi, Indonesia as a result of strike-slip faulting at shallow depth within the interior of the Molucca Sea Microplate that forms a part of the broader Sunda Plate. Focal mechanism solutions and distribution for the earthquakes indicate rupture occurred on a left-lateral NNW-SSE-to N-S-striking fault. This region has been characterized by complex tectonics in which motions of numerous small microplates are accommodating large-scale convergence between the Australia, Sunda, Pacific and Philippine Sea plates. In this paper, the Coulomb stress calculation verified the WNW-, nearly E-W-trending sinistral strike slip receiver fault in Sulawesi, which is consistent with the giant sinisterly strike-slip fault system across New Guinea, Pacific Tectonic System and the Tethys Tectonic System caused by the oblique convergence. The result has been reconciled within the modern GPS velocity field. | Gege Hui Sanzhong Li Pengcheng Wang Yanhui Suo Qian Wang Ian D.Somerville | 2018 | Science Bulletin2018，63，24： | 1 |
| 3 | A novel silicone derivative of natural osalmid(DCZ0858)induces apoptosis and cell cycle arrest in diffuse large B-cell lymphoma via the JAK2/STAT3 pathway显示文摘Diffuse large B-cell lymphoma(DLBCL)is a highly heterogeneous malignant tumor characterized by diffuse growth.DCZ0858 is a novel small molecule with excellent antitumor effects in DLBCL.This study explored in depth the inhibitory effect of DCZ0858 on DLBCL cell lines.Cell Counting Kit-8(CCK-8)and plate colony formation assays were used to evaluate cell proliferation levels.Flow cytometry was employed to analyze apoptosis and the cell cycle,and western blotting was used to quantify the expression of cell cycle regulators.The results indicated that DCZ0858 inhibited cell growth in a concentration-dependent and time-dependent manner while inducing no significant toxicity in normal cells.Moreover,DCZ0858 initiated cell apoptosis via both internal and external apoptotic pathways.DCZ0858 also induced cell cycle arrest in the G0/G1 phase,thereby controlling cell proliferation.Further investigation of the molecular mechanism showed that the JAK2/STAT3 pathway was involved in the DCZ0858-mediated antitumor effects and that JAK2 was the key target for DCZ0858 treatment.Knockdown of JAK2 partly weakened the DCZ0858-mediated antitumor effect in DLBCL cells,while JAK2 overexpression strengthened the effect of DCZ0858 in DLBCL cells.Moreover,a similar antitumor effect was observed for DCZ0858 and the JAK2 inhibitor ruxolitinib,and combining the two could significantly enhance cancer-suppressive signaling.Tumor xenograft models showed that DCZ0858 inhibited tumor growth in vivo and had low toxicity in important organs,findings that were consistent with the in vitro data.In summary,DCZ0858 is a promising drug for the treatment of DLBCL. | Kang Lu Bo Li Hui Zhang Zhijian Xu Dongliang Song Lu Gao Haiguo Sun Liping Li Yingcong Wang Qilin Feng Gege Chen Liangning Hu Rong Wei Yongsheng Xie Dandan Yu Xiaosong Wu Weiliang Zhu Jumei Shi | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 0 |
