| 1 | Late Mesozoic extensional tectonics of the Liaodong Peninsula massif:Response of crust to continental lithosphere destruction of the North China Craton显示文摘Unlike most Precambrian cratons that have thick sub-continental lithospheric roots,the Archean lithosphere beneath the North China Craton is thin (reduced from 200 km to about 80 km),and has been replaced by a geochemically juvenile lithospheric mantle.This is a unique regional geological event,which has attracted worldwide attention.In the North China Block,Late Mesozoic extensional tectonics is evident by low-angle detachment faults,syntectonic plutons bounded by ductile faults,metamorphic core complexes (MCC) and widespread Jurassic to Cretaceous half-grabens filled by continental terrigenous deposits and volcanic rocks.At a regional scale,these structures share the same NW-SE extensional direction,while maintaining their own individual kinematics.In other words,the MCC feature a top-to-the-NW sense of shear,and syntectonic plutons are typified by a top-to-the-SE shearing deformations.Geochronological results indicate that the extensional structures were formed between 130-120 Ma.These extensional events lead to magmatic rock emplacement,distributed at the footwall of the detachment faults.Two different exhumation stages can be identified based on regional structural and magmatic interpretation:a Jurassic slow or negligible exhumation and a Cretaceous fast one assisted by normal faulting.These two cooling stages correspond to distinct geodynamic processes that occurred during the Jurassic and Cretaceous.Extensional tectonics appear to have been insignificant before the Early Cretaceous,and the process may be demonstrated by partial melting of the crust.The second stage,dominated by an extensional regime,developed after ca 120 Ma,and is tentatively correlated with crustal extension caused by lithospheric removal of the North China Craton. | LIN Wei WANG QingChen WANG Jun WANG Fei CHU Yang CHEN Ke | 2011 | Science China Earth Sciences2011，54，6： | 24 |

| 3 | TGF-β1-supplemented decellularized annulus fibrosus matrix hydrogels promote annulus fibrosus repair显示文摘Annulus fibrosus(AF)repair remains a challenge because of its limited self-healing ability.Endogenous repair strategies combining scaffolds and growth factors show great promise in AF repair.Although the unique and beneficial characteristics of decellularized extracellular matrix(ECM)in tissue repair have been demonstrated,the poor mechanical property of ECM hydrogels largely hinders their applications in tissue regeneration.In the present study,we combined polyethylene glycol diacrylate(PEGDA)and decellularized annulus fibrosus matrix(DAFM)to develop an injectable,photocurable hydrogel for AF repair.We found that the addition of PEGDA markedly improved the mechanical strength of DAFM hydrogels while maintaining their porous structure.Transforming growth factor-β1(TGF-β1)was further incorporated into PEGDA/DAFM hydrogels,and it could be continuously released from the hydrogel.The in vitro experiments showed that TGF-β1 facilitated the migration of AF cells.Furthermore,PEGDA/DAFM/TGF-β1 hydrogels supported the adhesion,proliferation,and increased ECM production of AF cells.In vivo repair performance of the hydrogels was assessed using a rat AF defect model.The results showed that the implantation of PEGDA/DAFM/TGF-β1 hydrogels effectively sealed the AF defect,prevented nucleus pulposus atrophy,retained disc height,and partially restored the biomechanical properties of disc.In addition,the implanted hydrogel was infiltrated by cells resembling AF cells and well integrated with adjacent AF tissue.In summary,findings from this study indicate that TGF-β1-supplemented DAFM hydrogels hold promise for AF repair. | Qiang Wei Dachuan Liu Genglei Chu Qifan Yu Zhao Liu Jiaying Li Qingchen Meng Weishan Wang Fengxuan Han Bin Li | 2023 | Bioactive Materials2023，，1： | 3 |

Methods: A total of 453 people who met the inclusion criteria were investigated using a high-normal blood pressure human mass survey questionnaire. Results: of the 453 constitution types of high-normal blood pressure patients in Hebei area, 184 were the constitution of yin-yang harmony, accounting for 40.62% of the total;73 were the constitution of yang asthenia, accounting for 16.11% of the total;59 were the constitution of damp-heat, accounting for 13.02% of the total;52 were the constitution of qi asthenia, accounting for 11.48% of the total;8 were the allergic constitution, accounting for 1.77% of the total. In addition, of their syndrome types, the syndrome of liver-fire hyperactivity were accounting for 30.24%;the syndrome of excessive phlegm-dampness were accounting for 26.71%;the syndrome of yin-deficiency and yang-predominance were accounting for 23.18%;the syndrome of deficiency of both yin and yang were accounting for 19.87%. Conclusion: Among the high-normal blood pressure people in Hebei area, the proportion of the constitution of yin-yang harmony is the highest, followed by the constitution of yang asthenia, the constitution of damp-heat, and the constitution of qi asthenia, with the lowest percentage being the allergic constitution. In addition, when it comes to the syndrome of them, the proportion of the syndrome of liver-fire hyperactivity is the highest, followed by the syndrome of yin-deficiency and yang-predominance, and the lowest is the syndrome of deficiency of both yin and yang. | Qingchen Sun Xianbing Hou Hui Zhao Jiangjing Chu Yanjun Wang | 2018 | Journal of Advances in Medicine Science2018，1，3： | 0 |
