1Preface显示文摘Kaschin-Beck disease (KBD) is regarded as an endemic, chronic, high incidence and degenerative osteoarthropathie disease. The areas of endemic KBD are relatively stable and are correlated with specific geographical environments. In China, estimation of KBD patients in 1985 indicated more than 2 million people were severely affected in a broad region inhibited by over 30 million people. KBD endemic areas form a broad belt extending from northeast to southwest. The disease mostly appears in mountainous and hilly regions, and farmers are the major potentially affected ones. Hence KBD has been designated a national health priori-ty problem in China since 60’s.Peng AnProfessor Research Center for Eco-Environmental Sciences,Chinese Academy o Sciences 1991Journal of Environmental Sciences1991,3,4:5
2Oligomeric Procyanidins Induce Generation of Reactive Oxygen Species and Collapse of Mitochchondrial Membrane Potential in Glioblastoma Cell Lines显示文摘Objective The aim of the present study was to clarify the mechanism underlying glioma cell death upon oligomeric procyanidins (F2) exposure. Methods The cytotoxicity of F2 on U87 (human malignant glioblastoma cell line) and C6 (rat glioma cell line) cancer cells was evaluated, and changes of mitochondrial membrane potential (MMP) and production of reactive oxygen species (ROS) in drug-treated cells were monitored. Moreover, morphological changes associated with F2-induced cells death were examined. Results F2 induced a concentration-dependent increase in ROS production and decrease in MMP. Furthermore, pre-incubation with N-acetylcysteine (NAC) and rotenone (Rt), resulted in partial inhibition of F2-induced ROS generation and marked attenuation of cell death and the cytoplasmic vacuolization induced by F2. In addition, pretreatment with Rt markedly attenuated the MMP loss in F2-treated cells. However, pretreatment with NAC only markedly attenuated the MMP loss in F2-treated C6 cells. Conclusion The increase in ROS level is at least one of mechanisms associated with F2-induced glioma cell death as well as the cytoplasmic vacuolization formation that contribute to the cytotoxicity of F2 in glioma cells.ZHANG Feng-jiao1, YANG Jing-yu1, MOU Yan-hua1, SUN Bao-shan2, WANG Ji-ming3, WANG Fang1, WU Chun-fu1 1.

3Correlative ionospheric disturbances in the sunlit hemisphere during the flare on July 14,2000显示文摘Using GPS data obtained from GPS sites located on the sunlit hemisphere during the flare on July 14, 2000, the ionospheric response to the flare was analyzed. A kind of tiny correlative ionospheric fluctuations were revealed from the temporal total electron content (TEC) curves derived from GPS measurements, and the values of this kind of disturbances are about 1015 m-2. A comparative analysis of these disturbances and soft X-ray flux detected at GOES satellite during the flare is done. It is found that this kind of disturbances revealed in the temporal TEC curves did occur in a very large area of sunlit ionosphere and its behavior is mainly controlled by the characteristics of the flare’s extra radiation. Because the similar fluctuations are not found in the curve of soft X-ray flux, it is concluded that the flare extra radiation in EUV band should have corresponding fluctuations and it is the fluctuations that cause the TEC disturbances. The height, where the disturbances occur, should be in the FZHANG Donghe & XIAO ZuoDepartment of Geophysics, Peking University, Beijing 100871, China Qingdao Research Center, Chinese Research Institute of Radio-wave Propagation, Qingdao 266071, China Center for Space Science and Applied Research, Chinese Academy o 2002Chinese Science Bulletin2002,47,12:2

12Almandine megacrysts from Yingfengling Cenozoic basalt in Leizhou Peninsula and their parental magma origin显示文摘The garnet megacrysts from Yingfengling basalts are characterlzed by high FeO (>20%), CaO (7.02% -8.16%) and low MgO (5.88%-10.87%). Significant composition variations are observed in these megacrysts, of which Ni, V, Sc, Co, and HREE are positively correlated with their Mg# and Zr, Hf, Ga, Y, Sr, Nb, Zn and LREE-MREE are negatively correlated with Mg#. Megacryst parent magma is a highly evolved residual melt with strongl depletion in Ti, Sr, Hf, Nb and HREE. This parental magma was generated by more than 60% of crystallization fractionation of clinopyroxene, garnet, plagioclase and ilmenite from quartz tholeiitic magma. It has not erupted to the surface, but stayed at the upper mantle and formed the megacrystic cumulate. Megacrysts and their host basalt are in disequilibrium.YU Jinhai & S. Y. O’Reilly1.

17Water Vapor Variability in the Tropical Western Pacific from 20-year Radiosonde Data显示文摘The 20-year (1976-1995) daily radinsonde data at 17 stations in the tropical western Pacific was ana- lyzed. The analysls shows that the atmosphere is more humid in a warmer climate on seasonal,inter-annual and long-term (20-year) time scales, implying a positive water vapor feedback The vertlcal structure of the long-term trends in relative humidity (RH) is distinct from that on short-term (seasonal and inter-annual) time scales, suggesting that observed water vapor changes on short time scales could not be considered as a surrogate of long-term climate change. The increasing trend of RH (3%-5% / decade) in the upper troposphere is stronger than that in the lower troposphere (1 %-2% / decade). Such verthal structure would amplify positive water vapor feedback in comparison to the common assumption of constant RH changes vertically. The empicical orthogonal function (EOF) analysis of vertical structure of RH varmtions shows distinct features of the vert1cal structure of the first three EOFs. The first three EOFs are optimal for repre- sentation of water vapor profiles and provide some hints on physical mechanisms respons1ble for observed humidity variability. Vaisala radiosondes were used at nine stations, and VIZ radiosondes used at other eight stations The Vaisala data are corrected for temperature-dependence error using the correction siheme developed by NCAR / ATD and Vaisala. The comparison of Vaisala and VIZ data shows that the VIZ-measured RHs after October 1993 have a moist bias of - 10% at RHs < 20%. During 1976-1995, several changes in- cluding both instruments and reporting practice have been made at Vaisala stations and introduce errors to long-term RH variations.Junhong Wang, Harold L.

19Dilepton production in baryon-rich quark-gluon matter显示文摘From the full stopping scenario and considered the Drell-Yang background, the rapidity dependence of the dilepton production from the central collision 197Au + 197Au has been studied in the baryon-rich quark-gluon matter by using a relativistic hydrodynamic model.It can be found that the dilepton yield is strongly suppressed as increasing the rapidity. Such a characteristic signaling the formation of the baryon-rich quark-gluon matter can be tested in future experiments at CERN and Brookhaven.He Ze-Jun Zhang Jia-Ju Jiang Wei-Zhou and Liu Bo (CCAST World Laboratory P.
