| 1 | Preliminary Results of In-situ Stress Measurements along the Longmenshan Fault Zone after the Wenchuan M_s 8.0 Earthquake显示文摘Four months after the Wenchuan M_s 8 earthquake in western Sichuan,China,in situ stress measurements were carried out along the Longmenshan fault zone with the purpose of obtaining stress parameters for earthquake hazard assessment.In-situ stresses were measured in three new boreholes by using overcoring with the piezomagnetic stress gauges for shallow depths and hydraulic fracturing for lower depths.The maximum horizontal stress in shallow depths(~20 m) is about 4.3 MPa,oriented N19°E,in the epicenter area at Yingxiu Town,about 9.7 MPa,oriented N51°W,at Baoxing County in the southwestern Longmenshan range,and about 2.6 MPa,oriented N39°E,near Kangding in the southernmost zone of the Longmenshan range.Hydraulic fracturing at borehole depths from 100 to 400 m shows a tendency towards increasing stress with depth.A comparison with the results measured before the Wenchuan earthquake along the Longmenshan zone and in the Tibetan Plateau demonstrates that the stress level remains relatively high in the southwestern segment of the Longmenshan range,and is still moderate in the epicenter zone.These results provide a key appraisal for future assessment of earthquake hazards of the Longmenshan fault zone and the aftershock occurrences of the Wenchuan earthquake. | WU Manlu ZHANG Yueqiao LIAO Chunting CHEN Qunce MA Yinsheng WU Jinsheng YAN Junfeng OU Mingyi | 2009 | Acta Geologica Sinica(English Edition)2009，83，4： | 31 |
| 2 | Spatial and temporal change patterns of net primary productivity and its response to climate change in the Qinghai–Tibet Plateau of China from 2000 to 2015显示文摘The vegetation ecosystem of the Qinghai–Tibet Plateau in China,considered to be the′′natural laboratory′′of climate change in the world,has undergone profound changes under the stress of global change.Herein,we analyzed and discussed the spatial-temporal change patterns and the driving mechanisms of net primary productivity(NPP)in the Qinghai–Tibet Plateau from 2000 to 2015 based on the gravity center and correlation coefficient models.Subsequently,we quantitatively distinguished the relative effects of climate change(such as precipitation,temperature and evapotranspiration)and human activities(such as grazing and ecological construction)on the NPP changes using scenario analysis and Miami model based on the MOD17A3 and meteorological data.The average annual NPP in the Qinghai–Tibet Plateau showed a decreasing trend from the southeast to the northwest during 2000–2015.With respect to the inter-annual changes,the average annual NPP exhibited a fluctuating upward trend from 2000 to 2015,with a steep increase observed in 2005 and a high fluctuation observed from 2005 to 2015.In the Qinghai–Tibet Plateau,the regions with the increase in NPP(change rate higher than 10%)were mainly concentrated in the Three-River Source Region,the northern Hengduan Mountains,the middle and lower reaches of the Yarlung Zangbo River,and the eastern parts of the North Tibet Plateau,whereas the regions with the decrease in NPP(change rate lower than–10%)were mainly concentrated in the upper reaches of the Yarlung Zangbo River and the Ali Plateau.The gravity center of NPP in the Qinghai–Tibet Plateau has moved southwestward during 2000–2015,indicating that the increment and growth rate of NPP in the southwestern part is greater than those of NPP in the northeastern part.Further,a significant correlation was observed between NPP and climate factors in the Qinghai–Tibet Plateau.The regions exhibiting a significant correlation between NPP and precipitation were mainly located in the central and eastern Qinghai–Tibet Plateau,and the regions exhibiting a significant correlation between NPP and temperature were mainly located in the southern and eastern Qinghai–Tibet Plateau.Furthermore,the relative effects of climate change and human activities on the NPP changes in the Qinghai–Tibet Plateau exhibited significant spatial differences in three types of zones,i.e.,the climate change-dominant zone,the human activity-dominant zone,and the climate change and human activity interaction zone.These research results can provide theoretical and methodological supports to reveal the driving mechanisms of the regional ecosystems to the global change in the Qinghai–Tibet Plateau. | GUO Bing ZANG Wenqian YANG Fei HAN Baomin CHEN Shuting LIU Yue YANG Xiao HE Tianli CHEN Xi LIU Chunting GONG Rui | 2020 | Journal of Arid Land2020，12，1： | 12 |

| 4 | Co-seismic Faults and Geological Hazards and Incidence of Active Fault of Wenchuan Ms 8.0 Earthquake,Sichuan,China显示文摘There are two co-seismic faults which developed when the Wenchuan earthquake happened. One occurred along the active fault zone in the central Longmen Mts.and the other in the front of Longmen Mts.The length of which is more than 270 km and about 80 km respectively.The co-seismic fault shows a reverse flexure belt with strike of N45°-60°E in the ground,which caused uplift at its northwest side and subsidence at the southeast.The fault face dips to the northwest with a dip angle ranging from 50°to 60°.The vertical offset of the co-seismic fault ranges 2.5-3.0 m along the Yingxiu-Beichuan co-seismic fault,and 1.5-1.1 m along the Doujiangyan-Hanwang fault.Movement of the coseismic fault presents obvious segmented features along the active fault zone in central Longmen Mts. For instance,in the section from Yingxiu to Leigu town,thrust without evident slip occurred;while from Beichuan to Qingchuan,thrust and dextral strike-slip take place.Main movement along the front Longmen Mts.shows thrust without slip and segmented features.The area of earthquake intensity more thanⅨdegree and the distribution of secondary geological hazards occurred along the hanging wall of co-seismic faults,and were consistent with the area of aftershock,and its width is less than 40km from co-seismic faults in the hanging wall.The secondary geological hazards,collapses,landslides, debris flows et al.,concentrated in the hanging wall of co-seismic fault within 0-20 km from co-seismic fault. | MA Yinsheng LONG Changxing TAN Chengxuan WANG Tao GONG Mingquan LIAO Chunting WU Manlu SHI Wei DU Jianjun PAN Feng | 2009 | Acta Geologica Sinica(English Edition)2009，83，4： | 7 |
| 5 | SARS-CoV-2 promotes RIPK1 activation to facilitate viral propagation显示文摘Coronavirus disease 2019(COVID-19),caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),is the ongoing global pandemic that poses substantial challenges to public health worldwide.A subset of COVID-19 patients experience systemic inflammatory response,known as cytokine storm,which may lead to death.Receptor-interacting serine/threonine-protein kinase 1(RIPK1)is an important mediator of inflammation and cell death.Here,we examined the interaction of RIPK1-mediated innate immunity with SARS-CoV-2 infection.We found evidence of RIPK1 activation in human COVID-19 lung pathological samples,and cultured human lung organoids and ACE2 transgenic mice infected by SARS-CoV-2.Inhibition of RIPK1 using multiple smallmolecule inhibitors reduced the viral load of SARS-CoV-2 in human lung organoids.Furthermore,therapeutic dosing of the RIPK1 inhibitor Nec-1s reduced mortality and lung viral load,and blocked the CNS manifestation of SARS-CoV-2 in ACE2 transgenic mice.Mechanistically,we found that the RNA-dependent RNA polymerase of SARS-CoV-2,NSP12,a highly conserved central component of coronaviral replication and transcription machinery,promoted the activation of RIPK1.Furthermore,NSP12323L variant,encoded by the SARS-CoV-2 C14408T variant first detected in Lombardy,Italy,that carries a Pro323Leu amino acid substitution in NSP12,showed increased ability to activate RIPK1.Inhibition of RIPK1 downregulated the transcriptional induction of proinflammatory cytokines and host factors including ACE2 and EGFR that promote viral entry into cells.Our results suggest that SARS-CoV-2 may have an unexpected and unusual ability to hijack the RIPK1-mediated host defense response to promote its own propagation and that inhibition of RIPK1 may provide a therapeutic option for the treatment of COVID-19. | Gang Xu Ying Li Shengyuan Zhang Haoran Peng Yunyun Wang Dekang Li Taijie Jin Zhuohao He Yilun Tong Chunting Qi Guowei Wu Kangyun Dong Jizhou Gou Yang Liu Tongyang Xiao Jing Qu Liang Li Liang Liu Ping Zhao Zheng Zhang Junying Yuan | 2021 | Cell Research2021，31，12： | 6 |
| 6 | Piezomagnetic In-situ Stress Monitoring and its Application in the Longmenshan Fault Zone显示文摘The relative change of in-situ stress is an inevitable outcome of differential movement among the crust plates. Conversely, changes of in-situ stress can also lead to deformation and instability of crustal rock mass, trigger activity of faults, and induce earthquakes. Hence, monitoring real-time change of in-situ stress is of great significance. Piezomagnetic in-situ stress monitoring has good and longtime applications in large engineering constructions and geoscience study fields in China. In this paper, the new piezomagnetic in-situ stress monitoring system is introduced and it not only has overall improvements in measuring cell's structure and property, stressing and orienting way, but also enhances integration and intelligence of control and data transmission system, in general, which greatly promotes installing efficiency of measuring probe and quality of monitoring data. This paper also discusses the responses of new piezomagnetic system in large earthquake events of in-situ stress monitoring station at Qiaoqi of Baoxing and Wenxian of Gansu. The monitoring data reflect adjustments and changes of tectonic stress field at the southwestern segment of and the northern area near the Longmenshan fault zone, which shows that the new system has a good performance and application prospect in the geoscience field. Data of the Qiaoqi stress-monitoring station manifest that the Lushan Earthquake did not release stress of the southwestern segment of the Longmenshan fault zone adequately and there still probably exists seismic risk in this region in the future. Combined with absolute in-situ stress measurement, carrying out long-term in-situ stress monitoring in typical tectonic position of important regions is of great importance for researchers to assess and study regional crust stability. | ZHANG Chongyuan WU Manlu CHEN Qunce LIAO Chunting | 2014 | Acta Geologica Sinica(English Edition)2014，88，5： | 4 |
| 7 | Single-shot AAV-vectored vaccine against SARS-CoV-2 with fast and long-lasting immunity显示文摘Due to the insufficient long-term protection and significant efficacy reduction to new variants of current COVID-19 vaccines,the epidemic prevention and control are still challenging.Here,we employ a capsid and antigen structure engineering(CASE)strategy to manufacture an adenoassociated viral serotype 6-based vaccine(S663V-RBD),which expresses trimeric receptor binding domain(RBD)of spike protein fused with a biological adjuvant RS09.Impressively,the engineered S663V-RBD could rapidly induce a satisfactory RBD-specific IgG titer within 2 weeks and maintain the titer for more than 4 months.Compared to the licensed BBIBP-CorV(Sinopharm,China),a single-dose S663V-RBD induced more endurable and robust immune responses in mice and elicited superior neutralizing antibodies against three typical SARS-CoV-2 pseudoviruses including wild type,C.37(Lambda)and B.1.617.2(Delta).More interestingly,the intramuscular injection of S663V-RBD could overcome pre-existing immunity against the capsid.Given its effectiveness,the CASE-based S663VRBD may provide a new solution for the current and next pandemic. | Fuhua Wu Shuang Luo Yongshun Zhang Yangsen Ou Hairui Wang Zhaofei Guo Chunting He Shuting Bai Penghui He Min Jiang Xiaoyan Chen Guangsheng Du Xun Sun | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 2 |
