光学技术在生物医学中扮演着越来越重要的角色,其非电离辐射、高分辨率、高对比度和对生物组织异变高度灵敏等特性使其非常适用于生物组织的研究,包括成像、传感、治疗、刺激以及控制等。然而由于光折射因子在生物组织中的分布是不均匀的,光在生物组织中的传播会受到很强的散射影响,故纯光学技术的穿透深度和空间分辨率是“鱼和熊掌不可兼得”;高分辨率光学成像应用仅限于样品浅表层,当成像深度增加时分辨率急剧下降。实现光在深层生物组织里的高分辨率成像或应用是人们期盼已久的目标。近年来,为解决这一问题,研究者提出了不同的方法,例如切换到更长的光波长以减小组织散射系数,在信号检测时将漫射光转换为散射不明显的超声信号,逆转或者预先补偿由光的多次散射所带来的相位畸变,或借助光纤等微创光学通道实现深层生物组织的高分辨率光学成像、刺激等。基于团队在深层生物组织光学相关领域多年的耕耘,从光在生物组织中的传播特性出发,梳理和总结了近年来研究人员在光-声结合和光学波前整形技术等方面展开的诸多探索,以及在生物组织操控、成像、光学计算以及人工智能等领域中的应用尝试。虽然尚有诸多不足,但随着硬件设备的更新和计算技术的发展,在不远的将来有望实现活体深层生物组织光学高分辨率应用。在这一求索过程中,新方法和新能力将不断激发新的应用灵感,为光学尤其是生物医学光子学带来全新的理念和机遇。

The silicon (3560 m Ah/g) anode delivers a 10-times-higher specific capacity than that of the graphite counterpart (372m Ah/g). However, the large volumechange of Si during lithiation and delithiation processes always result in poor cycling stability. Lots of studies have been focused on the nanoengineering of Si [1],

Accelerated Exhumation During the Cenozoic in the Dabie Mountains: Evidence from Fission-Track Ages

引用

Acta Geologica Sinica(English Edition) 1998年第4期72卷 409-419页

作者： WANG Guocan YANG weiran Faculty of Earth Science China University of Geosciences Wuhan Hubei 430074

Abstract: Zircon and apatite fission-track dating indicates that the exhumation of the Dabie Mountains tended to be accelerated in the Cenozoic and that the exhumation of the eastern Dabie Mountains was more and more intense from south to north, which is in accordance with the more and more intense dissection from south to north, as is reflected by the modern geomorphologic features of the Dabie Mountains. The accelerated exhumation during the Cenozoic was related to the high elevation of the Dabie Mountains resulting from Late Cretaceous-Palaeogene detachment faulting and subsequent fault-block uplift and subsidence. The average elevation at that time was at least about 660 m higher than that at the present. The intense exhumation lagged behind intense uplift.

Geochronological Study of Caledonian Granulite and High-Pressure Gneiss in the Dabie Mountains

: Using the single—zircon evaporation technique and U—Pb method, the authors have conducted an isotope geochonological study of the Huilanshan granulite and Shima garnet-bearing plagioclase gneiss (“country rocks” of the Shima eclogite) in the Dabie Mountains. The study shows that these rocks have peak metamorphic ages of 443–455 Ma, which are essentially consistent with that of the Caledonian high—ultrahigh pressure eclogites. This indicates the existence of the Caledonian collisional orogeny in the Dabie Mountains.

Effects of L-lactic acid and D,L-lactic acid on viability and osteogenic differentiation of mesenchymal stem cells

引用

Chinese Science Bulletin 2013年第20期58卷 2404-2412,1-3页

作者： HE Yao WANG weiran DING JianDong State Key Laboratory of Molecular Engineering of Polymers Department of Macromolecular Science Advanced Materials Laboratory Fudan University

Poly(lactic acid) (PLA) and other aliphatic polyesters containing the unit of lactic acid are very popular biodegradable materials. While the degradation products, lactic acids, have been worried to bring with negative influence on biocompatibility, the focused experimental studies are less reported. This study is aimed at an in vitro examination of cytotoxicity of both L-lactic acid and D,L-lactic acid. Mesenchymal stem cells (MSCs) derived from rat bone marrow are employed to test the cytotoxicity of the lactic acids. Considering that the addition of lactic acids not only introduces lactate groups but also alters medium pH and ion strength, these three candidate effects are examined in a decoupled way by setting different comparison groups. The results confirm that the change of medium pH is the predominant factor. It has also been found that D-lactate is more cytotoxic than L-lactate at high concentrations. Yet, either L-or D,L-lactic acids seem acceptable in most of medical applications, because the cytotoxicity is significant only when the concentrations are as high as 20 mmol/L for both of them.

Tectonic Evolution of the North Depression of the South Yellow Sea Basin Since Late Cretaceous

引用

Journal of Ocean University of China 2016年第6期15卷 967-976页

作者： LI Nan LI weiran LONG Haiyan College of Marine Geoscience Ocean University of China

Abstract On the basis of subsidence history analysis and balanced cross-section analysis, the vertical uplift/subsidence history and horizontal extension/compression history of the north depression of the south Yellow Sea basin are quantitatively studied. The results show that the tectonic evolution of the north depression of the south Yellow Sea basin since late Cretaceous can be divided into a rifting phase （late Cretaceous to Paleogene） and a post-rifting phase （Neogene to Quaternary）. The rifting phase can be further subdivided into an initial rifting stage （late Cretaceous）, an intensive rifting stage （Paleocene）, a rifting termination stage （Eocene）, and an inversion-uplifting stage （Oligocene）. Together, this division shows the characteristics of an episodic-evolved intracontinental rift-depression basin. The deformation of the north depression of the south Yellow Sea basin since late Cretaceous was mainly fault-related. The horizontal extension and tectonic subsidence were controlled by the activity of faults. The differential evolution of faults also caused variations in local uplift/subsidence movements and the regional heterogeneity in extension. The late Cretaceous initial rifting of the north depression of the south Yellow Sea basin is related to the Pacific-Eurasia convergence. From the Paleocene intensive rifting stage to present, the Pacific-Eurasia convergence and India-Eurasia convergence have played important roles in the evolution of this region.
