| 1 | Near-resonance enhanced label-free stimulated Raman scattering microscopy with spatial resolution near 130 nm显示文摘High-resolution optical microscopes that can break 180 nm in spatial resolution set to conventional microscopies are much-needed tools.However,current optical microscopes have to rely on exogenous fluorescent labels to achieve high resolution in biological imaging.Herein,we report near-resonance enhanced label-free stimulated Raman scattering(SRS)microscopy with a lateral resolution near 130 nm,in which the high-resolution image contrast originates directly from a low concentration of endogenous biomolecules,with sensitivity gains of approximately 23 times.Moreover,by using a 0.3-m-long optical fiber,we developed hyperspectral SRS microscopy based on spectral focusing technology.Attributed to enhancements in spatial resolution and sensitivity,we demonstrated highresolution imaging of three-dimensional structures in single cells and high-resolution mapping of large-scale intact mouse brain tissues in situ.By using enhanced high-resolution hyperspectral SRS,we chemically observed sphingomyelin distributed in the myelin sheath that insulates single axons.Our concept opens the door to biomedical imaging with~130 nm resolution. | Yali Bi Chi Yang Yage Chen Shuai Yan Guang Yang Yaozu Wu Guoping Zhang Ping Wang | 2018 | Light(Science & Applications)2018，7，1： | 4 |
| 2 | Quality assessment of Chrysanthemum indicum Flower by simultaneous quantification of six major ingredients using a single reference standard combined with HPLC fingerprint analysis显示文摘Chrysanthemum indicum Flower is usually consumed as functional food. This paper described an improved total quality assessment method for Chrysanthemum indicum Flower by simultaneous quantitation using a single standard to determine multi-components method combined with high performance liquid chromatography fingerprint analysis. Six main components of Chrysanthemum indicum Flower including two flavonoids and four phenolic acids were simultaneously quantified using linarin as the internal reference standard. The method was fully validated with respect to linearity, precision, accuracy, robustness and stability.The validated method was successfully applied to the analysis of thirty three batches of Chrysanthemum indicum Flower samples. Under the same chromatographic conditions, fingerprint analysis in combination with Similarity analysis and principal component analysis was performed to identify the samples from different regions. In general, an effective assessment using a single standard to determinate multi-components method combined with fingerprint analysis make the reliable qualitation and quantitation analysis of Chrysanthemum indicum Flower available. | Jiao He Xiaoxue Wu Yali Kuang Tianyang Wang Kaishun Bi Qing Li | 2016 | Asian Journal of Pharmaceutical Sciences2016，11，2： | 3 |

| 5 | Geological characteristics and models of fault-foldfracture body in deep tight sandstone of the second member of Upper Triassic Xujiahe Formation in Xinchang structural belt of Sichuan Basin,SW China显示文摘In the second member of the Upper Triassic Xujiahe Formation(T_(3)x_(2))in the Xinchang area,western Sichuan Basin,only a low percent of reserves has been recovered,and the geological model of gas reservoir sweet spot remains unclear.Based on a large number of core,field outcrop,test and logging-seismic data,the T_(3)x_(2) gas reservoir in the Xinchang area is examined.The concept of fault-fold-fracture body(FFFB)is proposed,and its types are recognized.The main factors controlling fracture development are identified,and the geological models of FFFB are established.FFFB refers to faults,folds and associated fractures reservoirs.According to the characteristics and genesis,FFFBs can be divided into three types:fault-fracture body,fold-fracture body,and fault-fold body.In the hanging wall of the fault,the closer to the fault,the more developed the effective fractures;the greater the fold amplitude and the closer to the fold hinge plane,the more developed the effective fractures.Two types of geological models of FFFB are established:fault-fold fracture,and matrix storage and permeability.The former can be divided into two subtypes:network fracture,and single structural fracture,and the later can be divided into three subtypes:bedding fracture,low permeability pore,and extremely low permeability pore.The process for evaluating favorable FFFB zones was formed to define favorable development targets and support the well deployment for purpose of high production.The study results provide a reference for the exploration and development of deep tight sandstone oil and gas reservoirs in China. | LIU Junlong LIU Zhongqun LIU Zhenfeng LIU Yali SHEN Baojian XIAO Kaihua BI Youyi WANG Xiaowen WANG Ail FAN Lingxiao LI Jitongl | 2023 | Petroleum Exploration and Development2023，50，3： | 0 |
