| 1 | Structures of Syn-deformational Granites in the Longquanguan Shear Zone and Their Monazite Electronic Microprobe Dating显示文摘The Longquanguan shear zone is an important structural belt in the North China Craton, separating the underlying Fuping complex from the overlying Wutai complex. This shear zone has experienced three episodes of deformation: the first and main episode is a ductile top-to-ESE shear along the gently northwest-west dipping foliations, while the other two episodes are later collapse sliding. Prolonged granites parallel to the shear foliations make one of the main compositions of the Longquanguan shear zone. These granites experienced deformation to form mylonitic rocks when they emplaced during the first episode of deformation. Structural characters of the granites and their contacts to the country rocks indicate that these granites possibly resulted from in-situ partial re- melting by shearing, i.e., they are syn-deformational granites. Monazites in these mylonitic granites are magmatic minerals and their crystallization ages may represent ages of the magmatic events, and also the ages for the main deformation of the Longquanguan shear zone. Monazite electronic microprobe dating were carried on two samples of granite, which gives multiple peak ages, among which 1,846 Ma and 1,877 Ma are the main peak ages for the two samples. These ages represent the main deformation of the Longquanguan shear zone, which is consistent with the main regional geological event at about 1,850 Ma caused by the collision between the Eastern and Western Blocks in North China. The good match between the monazite ages and the corresponding regional tectono-thermal events shows the feasibility and reliability of monazite electronic microprobe dating. | ZHANG Jinjiang*, ZHAO Lan and LIU Shuwen The Key Laboratory of Orogenic Belts and Crustal Evolution, Ministry of Education School of Earth and Space Sciences, Peking University, Beijing 100871 | 2006 | Acta Geologica Sinica(English Edition)2006，80，6： | 9 |

| 10 | Effects of gentamicin on choline acetyltransferase expression in paraolivary nucleus neurons of guinea pigs显示文摘BACKGROUND:It is generally accepted that gentamicin can damage the cochlear nerve and acoustic nerve. In recent years,scholars have focused on neuronal changes and neurochemical information in the brainstem primary auditory center. OBJECTIVE: To explore morphological changes of choline acetyltransferase (ChAT)-positive neurons in the paraolivary nucleus (PON) of guinea pigs,and the effect on hearing following gentamicin injection. DESIGN,TIME AND SETTING: Randomized grouping and morphological observational study was performed at Animal Experimental Center of General Hospital of Shenyang Military Area Command of Chinese PLA from January to August 2007. MATERIALS: A total of 48 healthy guinea pigs were randomly divided into model (n=40) and control (n= 8) groups. The model group was divided into five subgroups at five time points of 1 and 3 days,1,2,and 3 weeks. METHODS: Guinea pigs in the model group were intraperitoneally injected with gentamicin,and those in the control group were intraperitoneally injected with the same volume of saline. MAIN OUTCOME MEASURES: Auditory brainstem-evoked potential was used to record auditory threshold; distribution and morphological changes of ChAT-positive neurons in the PON were observed with immunohistochemistry; section area and gray value of ChAT-positive neurons were measured with Quantimet 570 image-analyzing system. RESULTS: ChAT-positive neurons were diffusedly distributed in the PON. The majority was composed of large,round cells,with positive neurites that could be clearly observed. Following gentamicin injection,the positive neurons displayed an irregular outline,and their neurites began to shorten and disappear. The gray value increased with prolonged gentamicin administration (P<0.05). In addition,the somatic cross-sectional area was enlarged in the model group at 1 and 3 days after injection (P<0.05),whereas cell number significantly decreased at three weeks after injection (P<0.05). Starting at 3-4 days,behavioral features and auditory degrees became gradually aggravated with prolonged gentamicin administration (P<0.05). CONCLUSION: Gentamicin damaged ChAT-positive neurons in the PON,and long-term gentamicin treatment aggravated hearing impairment. | Mingguang Zhao Xiaochen Wang Yong Liang Peng Xie Xuejun Guo Jinjiang Li WeiWang | 2008 | Neural Regeneration Research2008，3，11： | 0 |
| 11 | Hydration of concrete containing calcium-enriched fly ash at subzero temperature显示文摘The compressive strength,hydration products and microstructure of concrete with calcium-enriched fly ash(CEFA) at different temperature were investigated.The result indicates that the hydration products age of 7 d at-15 ℃ are mainly ettringite and C-S-H,and fly ash particles remain original state.Standard curing was adapted after 7 d curing at-15 ℃.At the age of 35 d,C-S-H was found on the surface of fly ash particles.The hydration product of CEFA is mainly C-S-H gel,which can densify the microstructure of concrete. | ZHAO Yading,BA Hengjing,CUI Jinjiang,and HOU Zhiwei School of Materials Science and Engineering,Harbin Institute of Technology,Harbin 150001,China | 2007 | Rare Metals2007，26，S1： | 0 |
