Understanding the behavior of matter at extreme pressures of the order of a megabar(Mbar)is essential to gain insight into various physical phenomena at macroscales—the formation of planets,young stars,and the cores of super-Earths,and at microscales—damage to ceramic materials and high-pressure plastic transformation and phase transitions in *** dynamic compression of solids up to Mbar pressures,even a solid with high strength exhibits plastic properties,causing the induced shock wave to split in two:an elastic precursor and a plastic shock *** phenomenon is described by theoretical models based on indirect measurements of material *** advent of x-ray free-electron lasers(XFELs)has made it possible to use their ultrashort pulses for direct observations of the propagation of shock waves in solid materials by the method of phase-contrast ***,there is still a lack of comprehensive data for verification of theoretical models of different ***,we present the results of an experiment in which the evolution of the coupled elastic-plastic wave structure in diamond was directly observed and studied with submicrometer spatial resolution,using the unique capabilities of the x-ray free-electron laser(XFEL).The direct measurements allowed,for the first time,the fitting and validation of the 2D failure model for diamond in the range of several *** experimental approach opens new possibilities for the direct verification and construction of equations of state of matter in the ultra-high-stress range,which are relevant to solving a variety of problems in high-energy-density physics.

目的68Ga-1,4,7,10-四氮杂环十二烷-N,N′,N″,N′″-乙底酸-奥曲肽(DOTATOC)PET/CT显像有益于神经内分泌肿瘤(NET)患者。功能性NETs可自行分泌相关激素,从而引起临床症状。某些器官会对68Ga-DOTATOC有生理性摄取,但激素水平升高是否会影响这种生理性摄取尚不得而知。该研究的目的是探讨激素水平升高对68Ga-DOTATOC生理性摄取的影响。方法纳入167例已知或疑有NET的患者,其中促肾上腺皮质激素(ACTH)升高组10例、胃泌素升高组25例、胰岛素升高组7例、无激素升高组125例。比较各组患者不同器官的最大标准摄取值(SUVmax)。结果 ACTH升高组患者中,垂体、胰腺钩突及肾上腺SUVmax较无激素升高组SUVmax低(5.7±1.9与8.4±3.1, P=0.015; 4.7±3.5与6.4±2.8, P=0.037; 10.8±4.8与13.9±4.7,P=0.020)。各组甲状腺、胰腺体部、肝脏、脾脏、肠道及肾脏的68Ga-DOTATOC生理性摄取未见差异。结论 ACTH升高组的NET患者垂体、胰腺钩突及肾上腺的68Ga-DOTATOC生理性摄取显著降低,其他器官的摄取未受激素水平影响。
