1血清乙型肝炎病毒DNA水平的生物学梯度与肝细胞肝癌的风险性相关显示文摘Context: Serum hepatitis B virus (HBV) DNA level is a marker of viral replication and efficacy of antiviral treatment in individuals with chronic hepatitis B. Objective: To evaluate the relationship between serum HBV DNA level and risk of hepatocellular carcinoma. Design, Setting, and Participants: Prospective cohort study of 3653 participants (aged 30-65 years), who were seropositive for the hepatitis B surface antigen and seronegative for antibodies against the hepatitis C virus, recruited to a community-based cancer screening program in Taiwan between 1991 and 1992. Main Outcome Measure: Incidence of hepatocellular carcinoma during follow-up examination and by data linkage with the national cancer registry and the death certification systems. Results: There were 164 incident cases of hepatocellular carcinoma and 346 deaths during a mean follow-up of 11.4 years and 41 779 person-years of follow-up. The incidence of hepatocellular carcinoma increased with serum HBV DNA level at study entry in a dose-response relationship ranging from 108 per 100 000 person-years for an HBV DNA level of less than 300 copies/mL to 1152 per 100 000 person-years for an HBV DNA level of 1 million copies/mL or greater. The corresponding cumulative incidence rates of hepatocellular carcinoma were 1.3%and 14.9%, respectively. The biological gradient of hepatocellular carcinoma by serum HBV DNA levels remained significant (P< .001) after adjustment for sex, age, cigarette smoking, alcohol consumption, serostatus for the hepatitis B e antigen (HBeAg), serum alanine aminotransferase level, and liver cirrhosis at study entry. The dose-response relationship was most prominent for participants who were seronegative for HBeAg with normal serum alanine aminotransferase levels and no liver cirrhosis at study entry. Participants with persistent elevation of serum HBV DNA level during follow-up had the highest hepatocellular carcinoma risk. Conclusion: Elevated serum HBV DNA level (>10 000 copies/mL) is a strong risk predictor of hepatocellular carcinoma independent of HBeAg, serum alanine aminotransferase level, and liver cirrhosis.Chen C.-J.

6Spatial-Temporal Pattern and Driving Forces of Land Use Changes in Xiamen显示文摘Using Landsat TM data of 1988, 1998 and 2001, the dynamic process of the spatial-temporal characteristics of land use changes during 13 years from 1988 to 2001 in the special economic zone of Xiamen, China was analyzed to improve understanding and to find the driving forces of land use change so that sustainable land utilization could be practiced. During the 13 years cropland decreased remarkably by nearly 11304.95 ha. The areas of rural-urban construction and water body increased by 10 152.24 ha and 848.94 ha, respectively. From 1988 to 2001, 52.5% of the lost cropland was converted into rural-urban industrial land. Rapid urbanization contributed to a great change in the rate of cropland land use during these years. Land-reclamation also contributed to a decrease in water body area as well as marine ecological and environmental destruction. In the study area 1) urbanization and industrialization, 2) infrastructure and agricultural intensification, 3) increased affluence of the farming community, and 4) policy factors have driven the land use changes. Possible sustainable land use measures included construction of a land management system, land planning, development of potential land resources, new technology applications, and marine ecological and environmental protection.QUAN Bin CHEN Jian-Fei QIU Hong-Lie M.

7Variability in rainfall threshold for debris flow after the Chi-Chi earthquake in central Taiwan,China显示文摘The purpose of this study is to analyze variability in rainfall threshold for debris flow(critical rainfall for debris flow triggering) after the ML 7.3 Chi-Chi earthquake in central Taiwan in 1999. Two study sites with different geological conditions were surveyed in the earthquake area. Streambed surveys were conducted to continuously monitor debris flows between 1999 and 2006. During the 7-year study period,every debris flow event was identified,and the streambed characterized. Results show that the rainfall threshold for debris flow was remarkably lower just after the Chi-Chi Earthquake,but gradually recovered. To date,this rainfall threshold is still lower than the original level prior to the earthquake. This variability in rainfall threshold is closely related to the amount of sediment material in the initiation area of debris flow,which increased rapidly due to landslides resulting from the earthquake. With the increase in sediment material,the rainfall threshold was lowered severely during the first year following the Chi-Chi earthquake. However,heavy rainfalls mobilized the sediment material,causing debris flows and transporting sediment downstream. With the decrease in sediment material,the rainfall threshold recovered gradually over time. Furthermore,debris flows occurred only in the subbasins that had sufficient sediment material to cause significant movement. Hence,these results confirm that the sediment material in the initiation area of debris flow is a crucial component of the rainfall threshold for debris flow.C. L. SHIEH Y. S. CHEN Y. J. TSAI J. H.

11Blockade of cholecystokinin-2 receptor and cyclooxygenase-2 synergistically induces cell apoptosis, and inhibits the proliferation of human gastric cancer cells in vitro显示文摘Gastrin and cyclooxygenase-2(COX-2) playimportant roles in the carcinogenesis and progression ofgastric cancer.However,it remains unknown whether the combination of cholecystokinin-2(CCK-2) receptor antagonist plus COX-2 inhibitor exerts synergistic anti-tumor effects on human gastric cancer.Here,we demonstrated that the combination of AG-041R(a CCK-2 receptor antagonist) plus NS-398(a selective COX-2 inhibitor) treatment had synergistic effects on proliferation inhibition,apoptosis induction,down-regulation of Bcl-2 and up-regulation of Bax expression in MKN-45 cells.These results indicate that simultaneous targeting of CCK-2 receptor and COX-2 may inhibit gastric cancer development more effectively than targeting either molecule alone.(C)2008 Elsevier Ireland Ltd.All rights reserved.Sun, W.

16Land Suitability Assessment and Land Use Change in Fujian Province,China显示文摘To present the current status of land quality and distribution and the trends in land use change, the physical suitability of cropland and forestland and the associated changes in Fujian Province were evaluated and analyzed using data obtained from geographical information systems (GIS) and remote sensing (RS).Of the total land area of Fujian Province,first class suitable cropland accounted for only 4.21%, whereas unsuitable cropland accounted for 84.78%. The percentage of first class suitable cropland in the southeastern region (5.32%) was much higher than that in the northwestern area (2.91%).Only 13.63% of the existing cropland area consisted of first class cropland and 70.08% was classified as unsuitable for cultivation.Of the total land area of Fujian Province,the first class forestland comprised 55.25% and the unsuitable forestland (including third class) comprised 21.2%.The percentage of unsuitable forest area in the existing forestland was only 5.5%.From 1996 to 2001, cropland and unused land decreased significantly, whereas forestland and land used for urban and transport increased rapidly.Therefore,the major tasks ahead will be the land development for full grain production potential,the better coordination of allocating land to different uses, and the regulation inappropriate activities that damage agricultural ecosystems.QUAN Bin ZHU He-Jian CHEN Song-Lin M.

19A Review of the Functional and Anatomical Default Mode Network in Schizophrenia显示文摘Schizophrenia is a severe mental disorder characterized by impaired perception,delusions,thought disorder,abnormal emotion regulation,altered motor function,and impaired drive. The default mode network(DMN),since it was first proposed in 2001,has become a central research theme in neuropsychiatric disorders,including schizophrenia. In this review,first we define the DMN and describe its functional activity,functional and anatomical connectivity,heritability,and inverse correlation with the task positive network. Second,we review empirical studies of the anatomical and functional DMN,and anti-correlation between DMN and the task positive network in schizophrenia. Finally,we review preliminary evidence about the relationship between antipsychotic medications and regulation of the DMN,review the role of DMN as a treatment biomarker for this disease,and consider the DMN effects of individualized therapies for schizophrenia.Mao-Lin Hu Xiao-Fen Zong J.

20TREATMENT OF METALS, POLYMER FILMS, AND FABRICS WITHA ONE ATMOSPHERE UNIFORM GLOW DISCHARGE PLASMA(OAUGDP) FOR INCREASED SURFACE ENERGY AND DIRECTIONAL ETCHING显示文摘Direct exposure of samples to the active species of air generated by a One Atmosphere Uniform Glow Discharge Plasma (OAUGDP) has been used to etch and to increase the surface energy of metallic surfaces, photoresist, polymer films, and nonwoven fab- rics. The OAUGDP is a non-thermal plasma with the classical characteristics of a DC normal glow discharge that operates in air (and other gases) at atmospheric pres- sure. Neither a vacuum system nor batch processing is necessary. A wide range of applications to metals, photoresist, films, fabrics, and polymeric webs can be accom- modated by direct exposure of the workpiece to the plasma in parallel-plate reactors. This technolopy is simple, it produces effects that can be obtained in no other way at one atmosphere; it generates minimal pollutants or unwanted by-products; and it is suitable for individual sample or online treatment of metallic surfaces, wafers, films, and fabrics. Early exposures of solid materials to the OAUGDP required minutes to produce rela- tively small increases of surface energy. These durations appeared too long for com- mercial application to fast-moving webs. Recent improvements in OAUGDP gas com- position, power density, plasma quality, recireulating gas flow, and impedance match- ing of the power supply to the parallel plate plasma reactor have made it possible to raise the surface energy of a variety of polymeric webs (PP, PET PE etc.) to levels of 60 to 70 dynes/cm with one second of exposure. In air plasmas, the high surface ener- gies are not durable, and fall to 50 dynes/cm after periods of weeks to months. Here, we report the exposure of metallic surfaces, photoresist, polymeric films, and nonwo- ven fabrics made of PP and PET to an impedance matched parallel plate OAUGDP for durations ranging from one second to several tens of seconds. Data will be re- ported on the surface energy, wettability, wickability, and aging effect of polymeric films and fabrics as functions of time of exposure, and time after exposure; the rate and uniformity of photoresist etching; and the production of sub-micron structures by OAUGDP etching at one atmosphere.J.
