| 2 | Identification and differentiation of major components in three different “Sheng-ma” crude drug species by UPLC/Q-TOF-MS显示文摘Cimicifugae Rhizoma(Sheng ma) is a Ranunculaceae herb belonging to a composite family and well known in China,has been widely used in traditional Chinese medicine.The Pharmacopoeia of the People's Republic of China contains three varieties(Cimicifuga dahurica(Turcz.),Cimicifuga foetida L.and Cimicifuga heracleifolia Kom.) which have been used clinically as 'Sheng-ma'.However,the chemical constituents of three components of 'Sheng-ma' have never been documented.In this study,a rapid method for the analysis of the main components of 'Sheng-ma' was developed using ultra-high performance liquid chromatography with quadrupole-time-of-flight mass spectrometry(UPLC/Q-TOF-MS).The present study reveals the major common and distinct chemical constituents of C.dahurica,C.foetida and C.heracleifolia and also reports principal component and statistical analyses of these results.The components were identified by comparing the retention time,accurate mass,mass spectrometric fragmentation characteristic ions and matching empirical molecular formula with that of the published compounds.A total of 32 common components and 8 markers for different 'Sheng-ma' components were identified.These findings provide an important basis for the further study and clinical utilities of the three 'Sheng-ma' varieties. | Mengxue Fan Kunming Qin Fei Ding Yuting Huang Xiaoli Wang Baochang Cai | 2017 | Acta Pharmaceutica Sinica B2017，7，2： | 4 |

| 6 | A Study on Shear Wave Splitting for the Sequence of the Aftershocks of the Yao'an M_S6.5 Earthquake in Yunnan Province显示文摘The shear wave splitting study is based on data of the 3 component digital seismograms. This was recorded at 3 sets of stations, which were set up after the Yaoan M S6 5 earthquake, near its epicenter. The results indicate the following:①Shear wave splitting has been observed through analyzing 236 aftershock recordings within the shear wave window. ②The time delay was mostly in the range of 3 5~10 5ms/km and the average was 7 0ms/km.③The polarization direction of the fast split S wave was mostly in the range of N140°E~N164°E and the average was N152 4°E. ④The preferred polarization direction for the fast shear wave was different from the direction of the seismogenic structure of the mainshock (Maweijing fault) and the direction of the rupture of the aftershocks, but similar to the principal compressional axis of the regional stress field. ⑤Shear wave splitting for sequence of the aftershocks of the Yaoan earthquake was the result of anisotropy of EDA cracks controlled by stress field. | Qian Xiaodong, Li Baiji and Qin JiazhengSeismological Bureau of Yunnan Province, Kunming 650041, China | 2003 | Earthquake Research in China2003，17，1： | 0 |
| 7 | Analysis on the Regional Features of Coda Attenuation Before and After the 1992 Qina (M_S= 5.4, 5.1) Earthquakes in WYEPSA显示文摘Using the theoretical model of coda scattering from local earthquakes, we have studied the features of time-space variations of the attenuation rate β of coda amplitude and coda Qc-1 values before and after the Qina earthquakes (MS5.4 and MS5.1) in Dec. 1992 in West Yunnan Earthquake Prediction Study Area (WYEPSA). The study results show that the attenuation rate of coda amplitude has remarkable regional inhomogeneity in the near-field (△ <50 km) around the main shock: β = 0.0076 s-1 and Qc-1 = 0.0056 during the main shock while (3 = 0.0209 s-1 and Qc-1 = 0.0153 during the aftershock. The Qc-1 value shows an approximate 3-foid variation before and after the main shock. We have also obtained the regional averages of β = 0.0235 s-1 and Qc-1 = 0.0153, which show that the coda attenuation in surrounding areas (△ > 50 km) far away from the epicenter of the main shock did not change much before and after the main shock. The evolution of Qc-1 values of the main seismic sequence with time has passed | Qin Jiazheng, Liu Zuyin, and Long Xiaofan Seismological Bureau of Yunnan Province, Kunming 650041, China | 1996 | Earthquake Research in China1996，10，2： | 0 |
| 8 | NLRP3 inflammasome activation is involved in manganeseinduced immunotoxicity显示文摘Manganese(Mn)is an essential trace element for the normal development of human body.It plays an important role in the regulation of cellular energy level,blood sugar balance,function of immunity,and bone growth,and works as an essential part of many indispensable enzyme functions.Meanwhile,overexposure to divalent manganese(Mn2+)could cause a series of physiological and pathological dysfunctions,and Mn has been recognized as an environmental toxicant and an occupational hazard[1].With the increasing exposure risk in environmental settings,such as contaminated food and polluted water and soil,Mn2+-induced toxicities have become an important public health issue. | Jing Ji Haiyi Yu Lei Liao Jiaojiao Li Kunming Qin Jinyang Shen Bo Guo Xiaofu Shao Jinming Ma Jingquan Dong Song Gao | 2022 | Acta Biochimica et Biophysica Sinica2022，54，2： | 0 |
