2Prevalence of HPV Infection And Cervical Intraepithelial Neoplasia And Attitudes towards HPV Vaccination among Chinese Women Aged 18-25 in Jiangsu Province显示文摘Objective:Few data are available on the epidemiology of HPV and cervical cancer among Chinese women younger than 25 years old.This study aimed to estimate the HPV infection rate and the prevalence of cervical intraepithelial neoplasia(CIN) in women aged 18-25,as well as their knowledge of and attitudes towards HPV vaccination.Methods:A population-based cervical cancer screening study was conducted on women aged 18-25 in Jiangsu province in 2008.Participants provided socio-demographic,reproductive and behavioral information and completed a survey about their knowledge of and attitudes towards HPV vaccination.Women then underwent a gynecologic exam to provide two cervical exfoliated cell samples for high risk HPV DNA testing and liquid-based cytology(LBC) as well as visual inspection with acetic acid(VIA).Women testing positive for any test were referred to colposcopy and biopsy.The gold standard for diagnosis of cervical lesions was directed or random biopsies.Results:Within the sample of 316 women,3.4% of them were diagnosed with CIN grade 2 or worse lesions and 17.1% were found to be positive for HPV DNA.Among these young women,extra-marital sexual behavior of them(OR=2.0,95%CI:1.1-3.8) or their husbands(OR=2.6,95%:1.4-4.7) were associated with an increased risk of HPV positivity.Although overall HPV awareness was low,after a brief educational intervention,98.4% reported they would electively receive HPV vaccination and would also recommend that their daughters be vaccinated.However,most urban and rural women reported their ideal maximum out-of-pocket contribution for HPV vaccination to be less than 500 RMB and 50-100 RMB,respectively.Conclusion:Our study indicates cervical disease burden is relatively high among sampled Chinese women aged 18-25.Appropriate educational interventions for female adolescents and strategies to subsidize vaccine costs are definitely needed to ensure the effectiveness of vaccination campaigns in China.Shang-ying Hu Ying Hong Fang-hui Zhao Adam K.

3REE geochemistry of suspended sediments from the rivers around the Yellow Sea and provenance indicators显示文摘Rare earth element (REE) compositions of the suspended sediments from the rivers around the Yellow Sea were different in that Korean river sediments (Han, Keum and Yeongsan Rivers) yield stronger fractionations than Chinese river sediments (Changjiang, Huanghe and Yalujiang), shown by obvious enrichments of LREE (light rare earth element) relative to UCC (upper continental crust). Variations of source rock compositions in the drainage basins are responsible for the differences of REE compositions between the river sediments. REE fractionation parameters including (La/Yb)UCC and (Gd/Yb)UCC as well as the ratios of La/Sc and Th/Sc can be treated as proper proxies for identifying the Chinese river sediments from those Korean river matters, and furthermore, for studying the provenances and paleoenvironmental changes of the marginal seas of China.YANG Shouye LI Congxian C.

4Environmental Problems From Tea Cultivation in Japan and a Control Measure Using Calcium Cyanamide显示文摘A field experiment, involving lime N (calcium cyanamide, CaCN2) fertilization as a control measure, was conducted to study environmental problems induced by long-term heavy N application in Japanese tea fields. Long-term tea cultivation caused serious soil acidification. Seventy-seven percent of the 70 tea fields investigated had soil pH values below 4.0, and 9% below 3.0, with the lowest value of 2.7. Moreover, excess N application in tea fields put a threat to plant growth, induced serious nitrate contamination to local water, and caused high nitrous oxide loss. Compared with the conventional high N application treatment (1100 kg N ha-1) without lime N, the low N application (400 kg N ha-1) with calcium cyanamide effectively stopped soil acidification as well as achieved the same or slightly higher levels in tea yield and in total N and amino acid contents of tea shoots. The application of calcium cyanamide could be a suitable fertilization for the prevention of environmental problems in tea cultivation.K. OH T. KATO LI Zhong-Pei LI Fa-Yun 2006Pedosphere2006,16,6:26
5Impact of Land Use and Soil Fertility on Distributions of Soil Aggregate Fractions and Some Nutrients显示文摘The size distribution of water-stable aggregates and the variability of organic C,N and P contents over aggregate size fractions were studied for orchard,upland,paddy,and grassland soils with high,medium,and low fertility levels.The results showed that > 5 mm aggregates in the cultivated upland and paddy soils were 44.0% and 32.0%,respectively,less than those in the un-tilled orchard soil.Organic C and soil N in different size aggregate fractions in orchard soil with high fertility were significantly higher than those of other land uses.However,the contents of soil P in different size aggregates were significantly greater in the paddy soil as compared to the other land uses.Soil organic C,N and P contents were higher in larger aggregates than those in smaller ones.The amount of water-stable aggregates was positively correlated to their contribution to soil organic C,N and P.For orchard and grassland soils,the > 5 mm aggregates made the greatest contribution to soil nutrients,while for upland soil,the 0.25-0.053 mm aggregates contributed the most to soil nutrients.Therefore,the land use with minimum disturbance was beneficial for the formation of a better soil structure.The dominant soil aggregates in different land use types determined the distribution of soil nutrients.Utilization efficiency of soil P could be improved by converting other land uses to the paddy soil.LIU Xiao-Li HE Yuan-Qiu H.

11Temporal Variability in Soil CO_2 Emission in an Orchard Forest Ecosystem显示文摘Temporal variability in soil CO2 emission from an orchard was measured using a dynamic open-chamber system for measuring soil CO2 efflux in Heshan Guangdong Province, in the lower subtropical area of China. Intensive measurements were conducted for a period of 12 months. Soil CO2 emissions were also modeled by multiple regression analysis from daily air temperature, dry-bulb saturated vapor pressure, relative humidity, atmospheric pressure, soil moisture, and soil temperature. Data was analyzed based on soil moisture levels and air temperature with annual data being grouped into either hot-humid season or relatively cool season based on the precipitation patterns. This was essential in order to acquire simplified exponential models for parameter estimation. Minimum and maximum daily mean soil CO2 efflux rates were observed in November and July, with respective rates of 1.98 ± 0.66 and 11.04 ± 0.96 μmol m-2 s-1 being recorded. Annual average soil CO2 emission (FCO2) was 5.92 μmol m-2 s-1. Including all the weather variables into the model helped to explain 73.9% of temporal variability in soil CO2 emission during the measurement period. Soil CO2 efflux increased with increasing soil temperature and soil moisture. Preliminary results showed that Q10, which is defined as the difference in respiration rates over a 10 -C interval, was partly explained by fine root biomass. Soil temperature and soil moisture were the dominant factors controlling soil CO2 efflux and were regarded as the driving variables for CO2 production in the soil. Including these two variables in regression models could provide a useful tool for predicting the variation of CO2 emission in the commercial forest soils of South China .LI Yue-Lin D. OTIENO K.

13Recovery and Leaching of ^(15)N-Labeled Coated Urea in a Lysimeter System in the North China Plain显示文摘The effectiveness of polyolefin-coated urea (Meister-5 and Meister-10; CU) in a wheat (Triticum aestivum L.)-maize (Zea mays L.) rotation system was studied in lysimeter plots located in the North China Plain for three consecutive maize- wheat-maize cropping seasons. An isotopic method was used to compare the fate of CU to that of non-coated urea (NCU), and N application rates of 0, 100, 150 and 225 kg N ha-1 were evaluated. The results showed that the nitrogen use effciency (15NUE) of CU was 13.3%–21.4% greater than that of NCU for the first crop. Alternatively, when the difference method was applied (apparent NUE), no significant variations were observed among treatments in all three seasons. Although inorganic N leached from the 1.3 m layer was less than 1% of the total applied N, unidentified losses of 15N (losses of 15N = 15N applied as fertilizer – 15N absorbed by crops – 15N remaining in the 0–0.2 m layer – 15N leached from the 1.3 m layer) in CU-treated plots were 24.2%–26.5% lower than those of NCU-treated plots. The nitrate concentration in the 0–1.3 m layer of CU plots at the end of the experiment was 53% lower than that of NCU-treated plots. Thus, CU increased crop N uptake from fertilizer and reduced unidentified losses of applied N, which can reduce the risk of groundwater pollution.LI Gui-Hua ZHAO Lin-Ping ZHANG Shu-Xiang Y. HOSEN K.

15Estimating emissions of HCFC-22 and CFC-11 in China by atmospheric observations and inverse modeling显示文摘This paper presents the estimation of Chinese emissions of HCFC-22 and CFC-11 in 2009 by an inverse modeling method based on in-situ measurement data from the Shangdianzi Global Atmosphere Watch (GAW) Regional Station (SDZ) and atmospheric transport simulations. After inversion (a-posteriori) estimates of the Chinese emissions in 2009 increased by 6.6% for HCFC-22 from 91.7 (± 83.6) to 98.3 (± 47.4) kt/yr and by 22.5% for CFC-11 from 13 (±12.6) to 15.8 (±7.2) kt/yr compared to an a-priori emission. While the model simulation with a-priori emissions already captured the main features of the observed variability at the measurement site, the model performance (in terms of correlation and mean-square-error) improved using a-posteriori emissions. The inversion reduced the root-mean-square (RMS) error by 4% and 10% for HCFC-22 and CFC-11, respectively.AN XingQin HENNE Stephan YAO Bo VOLLMER Martin K.
