| 4 | A new way to generate seismic waves for continental crustal exploration显示文摘An airgun experiment was conducted in a reservoir,with the total volume of the airgun array being 6000 cubic inch. The energy released by one excitation was estimated to be 6.68×106 J,which corresponded to a 3.4 kg TNT explosion. A 180 km long profile composed of 100 portable short period seismometers was deployed as a receiver system of the airgun signals. Two remarkable results can be drawn from the experiment: (1) the airgun explosion is harmless to the dam and the fish,and this kind of airguns can be regarded as a green and environmental protection seismic source on land; (2) seismic wave gener-ated by this airgun source can be recorded by permanent stations with offset larger than 200 km. And the wave amplitudes recorded by nearby and remote stations are equivalent to the wave generated by 800 kg dynamite explosion. The airguns can be used as a light to illuminate the continental crustal structure of an area of about 100000 km2. | CHEN Yong ZHANG XianKang QIU XueLin GE HongKui LIU BaoJin WANG BaoShan | 2007 | Chinese Science Bulletin2007，52，16： | 24 |

| 6 | Tectonic Taphrogenesis and Paleoseismic Records from the Yishu Fault Zone in the Initial Stage of the Caledonian Movement显示文摘The Yishu fault zone (mid-segment of the Tanlu fault zone) was formed in the Presinian. Periodic tectonic activities and strong seismic events have occurred along the fault zone. During the initial stage of the Caledonian Movement, with the proceeding of the marine transgression from the Yishu paleo-channel to the western Shandong, uneven thick sediments, composed mainly of sand, mud and carbonates of littoral, lagoon, and neritic facies, were deposited in the Yishu fault zone and western Shandong, and constructed the bottom part of the Lower Cambrian consisting of the Liguan and Zhushadong formations. Through field observations and the lab-examinations, various paleoseismic records have been discovered in the Liguan Formation and the Zhushadong Formations of the Yishu fault zone and its vicinity, including some layers with syn-sedimentary deformation structures that were triggered by strong earthquakes (i.e. seismite, seismo-olistostrome, and seismo-turbidite). Paleoseismic records developed in the Zhushadong Formation are mainly seismites with soft-sediment deformation structures, such as liquefied diapir, small liquefied-carbonate lime-mud volcano, liquefied vein, liquefied breccia, convolute deformation (seismic fold), graded fault, soft siliceous vein, and deformation stromatolite, as well as seismites with brittle deformation structures of semiconsolidated sediments. Paleoseismic records preserved in the Liguan Formation are not only seismo-olistostrome with a slump fold, load structure, and ball-and-pillows, but also seismo-turbidite with convolution bedding, graded bedding and wavy-bedding. However, in the western Shandong area, the closer to the Yishu fault zone, the greater the thickness of the Liguan Formation and the Zhushadong Formation, the greater the number and type of layers with paleoseismic records, and the higher the earthquake intensity reflected by associations of seismic records. This evidence indicates that tectonic taphrogenesis accompanied by strong earthquake events occurred in the Yishu fault zone during the initial stage of the Caledonian Movement, which embodied the break-up of the Sino-Korean Plate along the Paleo-Tanlu fault zone at that time. | TIAN Hongshui ZHANG Zengqi ZHANG Banghua ZHU Jiewang SANG Zhongxi LI Hongkui | 2013 | Acta Geologica Sinica(English Edition)2013，87，4： | 18 |

| 8 | A two-step lineage reprogramming strategy to generate functionally competent human hepatocytes from fibroblasts显示文摘Terminally differentiated cells can be generated by lineage reprogramming,which is,however,hindered by incomplete conversion with residual initial cell identity and partial functionality. Here, we demonstrate a new reprogramming strategy by mimicking the natural regeneration route, which permits generating expandable hepatic progenitor cells and functionally competent human hepatocytes. Fibroblasts were first induced into human hepatic progenitor-like cells (hHPLCs), which could robustly expand in vitro and efficiently engraft in vivo. Moreover, hHPLCs could be efficiently induced into mature human hepatocytes (hiHeps) in vitro, whose molecular identity highly resembles primary human hepatocytes (PHHs). Most importantly, hiHeps could be generated in large quantity and were functionally competent to replace PHHs for drug-metabolism estimation, toxicity prediction and hepatitis B virus infection modeling. Our results highlight the advantages of the progenitor stage for successful lineage reprogramming. This strategy is promising for generating other mature human cell types by lineage reprogramming. | Bingqing Xie Da Sun Yuanyuan Du Jun Jia Shicheng Sun Jun Xu Yifang Liu Chengang Xiang Sitong Chen Huangfan Xie Qiming Wang Guangya Li Xuehui LYU Hui Shen Shiyu Li Min Wu Xiaonan Zhang Yue Pu Kuanhui Xiang Weifeng Lai Peng Du Zhenghong Yuan Cheng Li Yan Shi Shichun Lu Hongkui Deng | 2019 | Cell Research2019，29，9： | 9 |
| 9 | Establishment of intestinal organoid cultures modeling injury-associated epithelial regeneration显示文摘The capacity of 3D organoids to mimic physiological tissue organization and functionality has provided an invaluable tool to model development and disease in vitro.However,conventional organoid cultures primarily represent the homeostasis of self-organizing stem cells and their derivatives.Here,we established a novel intestinal organoid culture system composed of 8 components,mainly including VPA,EPZ6438,LDN193189,and R-Spondin 1 conditioned medium,which mimics the gut epithelium regeneration that produces hyperplastic crypts following injury;therefore,these organoids were designated hyperplastic intestinal organoids(Hyper-organoids).Single-cell RNA sequencing identified different regenerative stem cell populations in our Hyper-organoids that shared molecular features with in vivo injury-responsive Lgr5+stem cells or Clu+revival stem cells.Further analysis revealed that VPA and EPZ6438 were indispensable for epigenome reprogramming and regeneration in Hyper-organoids,which functioned through epigenetically regulating YAP signaling.Furthermore,VPA and EPZ6438 synergistically promoted regenerative response in gut upon damage in vivo.In summary,our results demonstrated a new in vitro organoid model to study epithelial regeneration,highlighting the importance of epigenetic reprogramming that pioneers tissue repair. | Molong Qu Liang Xiong Yulin Lyu Xiannian Zhang Jie Shen Jingyang Guan Peiyuan Chai Zhongqing Lin Boyao Nie Cheng Li Jun Xu Hongkui Deng | 2021 | Cell Research2021，31，3： | 9 |
| 10 | Impending HRT wave precursors to the Wenchuan M_s8.0 earthquake and methods of earthquake impending prediction by using HRT wave显示文摘We deployed four geo-electric monitoring stations in Sichuan and Yunnan provinces from 2004, using the new generation of equipment (PS-100) and technologies to capture the HRT wave earthquake precursor. Before the Wenchuan Ms8.0 earthquake, we recorded the HRT wave precursor at the only operating station in Hongge (HG, Δ=465 km) and found that significant impending signal had been recorded at the station in the early morning ( 0―5 am) of 12th of May, 2008. The precursor for this earthquake is consistent with precursors recorded for other strong earthquakes. The measured physical properties (geo-resistivity and telluric-current) show tidal wave period oscillations from several days to several months before the earthquakes and the amplitude of such HT oscillation increases significantly towards the occurrence of an earthquake. These HT and RT waves from the epicenter have a causal relationship with the earthquakes that happened several days later. The arrival time of two RT waves is proportional to the distance from the station to the epicenter. The estimated natural decay of the amplitude is correlated with the natural period (T0) of the earthquake fault, which is proportional to the fault length. From this relationship, we can predict the earthquake magnitude. For magnitude 6―9 earthquakes, the natural period is about 1―6 hours. Such oscillation comes from the epicenter area and they can propagate several thousand kilometers in the Earth's crust. Before a strong earthquake in the shallow crust, the conductive pore fluid will experience major changes before the fault rapture. Such fluid change will emit an oscillation in the pore fluid pressure. This is the mechanism for the HRT wave generation. Since the China Earthquake Administration funded the HRT wave short-term earth-quake prediction project in 2003, the first record of HRT precursor wave has been recorded from the 2004-12-26 Sumatra Mw9.0 earthquake with the largest epicentre distance Δ=2900 km. Thereafter, we have captured HRT waves from more than twenty strong earthquakes, which are well-matched and show repeatability, consistency and regularity. All our observation with the HRT waves demonstrate that HRT wave precursors to earthquakes indeed exist. Strong earthquakes can be predicted and short-term and impending earthquake prediction is achievable in the very near future. From all the observations, including the ones at HG station from Wenchuan Ms8.0 earthquake, we conclude that using HRT wave to predict earthquakes is feasible. | QIAN FuYe ZHAO BiRu QIAN Wei ZHAO Jian HE ShiGen ZHANG HongKui LI ShiYu LI ShaoKun YAN GuLiang WANG ChengMin SUN ZhenKai ZHANG DongNing LU Jun ZHANG Ping YANG GuoJun SUN JiaLin GUO ChunSheng TANG YuXiong XU JianMing XIA KunTao JU Hang YIN BangHong LI Ming YANG DongSheng QI WeiLuo HE TaiMing GUAN HuaPing ZHAO YuLin | 2009 | Science China Earth Sciences2009，52，10： | 8 |

| 13 | Study of the Reservoir Damage during Cyclic Injection and Extraction Process in the Hutubi Gas Storage显示文摘During the injection and extraction process in gas storage,cyclic loading stress is applied to the reservoir pore structure,affecting the capacity and service life of gas storage. To study the influence of cyclic injection and extraction on reservoir physical property,a finite-element model of reservoir elastoplastic damage under the effect of pore pressure is established based on elastoplastic mechanics and fatigue-damage mechanics. Considering the mechanical property of the Hutubi reservoir and the injection-extraction mode of gas storage,the finite-element model is used to study the pore pressure and porosity change,fault safety,and ground surface deformation. The results show that the change in pore pressure and porosity,the deformation of the Hutubi fault,as well as the uplift and sink of the grounds surface are controlled by the fatigue damage of the reservoir pore structure during the injection-extraction process. After a 6-year service life, the cumulative deformation of the reservoir pore reaches its limit,causing pore structure collapse and porosity decrease. As a result,storage capacity declines and the ground surface starts to sink. Through this study,the safety of the Hutubi gas storage is evaluated,and some suggestions for field operations are offered. | Wang Jianbo Ge Hongkui Wang Xiaoqiong Liu Tongyuan Liu Dunqing Zhang Yanjun Wu Shan | 2018 | Earthquake Research in China2018，32，2： | 4 |

| 18 | Construction of Dual-Biofunctionalized Chitosan/Collagen Scaffolds for Simultaneous Neovascularization and Nerve Regeneration显示文摘Biofunctionalization of artificial nerve implants by incorporation of specific bioactive factors has greatly enhanced the success of grafting procedures for peripheral nerve regeneration.However,most studies on novel biofunctionalized implants have emphasized the promotion of neuronal and axonal repair over vascularization,a process critical for long-term functional restoration.We constructed a dual-biofunctionalized chitosan/collagen composite scaffold with Ile-Lys-Val-Ala-Val(IKVAV)and vascular endothelial growth factor(VEGF)by combining solution blending,in situ lyophilization,and surface biomodification.Immobilization of VEGF and IKVAV on the scaffolds was confirmed both qualitatively by staining and quantitatively by ELISA.Various single-and dual-biofunctionalized scaffolds were compared for the promotion of endothelial cell(EC)and Schwann cell(SC)proliferation as well as the induction of angiogenic and neuroregeneration-associated genes by these cells in culture.The efficacy of these scaffolds for vascularization was evaluated by implantation in chicken embryos,while functional repair capacity in vivo was assessed in rats subjected to a 10mm sciatic nerve injury.Dual-biofunctionalized scaffolds supported robust EC and SC proliferation and upregulated the expression levels of multiple genes and proteins related to neuroregeneration and vascularization.Dual-biofunctionalized scaffolds demonstrated superior vascularization induction in embryos and greater promotion of vascularization,myelination,and functional recovery in rats.These findings support the clinical potential of VEGF/IKVAV dual-biofunctionalized chitosan/collagen composite scaffolds for facilitating peripheral nerve regeneration,making it an attractive candidate for repairing critical nerve defect.The study may provide a critical experimental and theoretical basis for the development and design of new artificial nerve implants with excellent biological performance. | Guicai Li Qi Han Panjian Lu Liling Zhang Yuezhou Zhang Shiyu Chen Ping Zhang Luzhong Zhang Wenguo Cui Hongkui Wang Hongbo Zhang | 2020 | Research2020，，1： | 2 |
