Abstract: 根据2000年6月至7月夏季藻华期在11个监测站10个航次获取的表层浮游植物和现场测定的理化参数数据,采用多元分析方法揭示浮游植物聚群在污染胁迫下的动态特征。结果表明:(1)该区调查期间浮游植物群落的物种多样性时空变异显著,各站多样性指数值(H′)变动在0.45—4.23之间;(2)聚类分析和多维排序(MDS)结果显示,浮游植物聚群可分为3个与浮游植物阶段性演替以及各水域间不同的理化特征相关联的群落。群落Ⅰ系2000年6月赤潮暴发时主要出现于西海域的低盐港湾群落,由微型(nano一)浮游植物组成,包括硅藻门的角毛藻、骨条藻等属种类以及金藻门的单鞭金藻属种类等,如中肋骨条藻(Skeletonema costatum)、聚生角毛藻(Chaetoceros socialis)等和一种单鞭金藻(Chromulina sp.)(未鉴定到种,藻径3~5μm),它们是赤潮原因种。群落Ⅱ和群落Ⅲ都以小型(micro-)浮游植物占优势。群落Ⅱ为赤潮前后广泛出现于调查区各水域的亚热带近岸广布群落,代表种有具槽帕拉藻(Paralia sulcata)、翼鼻状藻(Proboscia alata)、菱形海线藻(Thalassionema nitzschioides)和冰河拟星杆藻(Asterionellopsis glacialis).群落Ⅲ主要分布于本海区东一东北部,由我国东南沿海常见的近海广布性种类组成,包括旋链角毛藻(Chaetoceros curvisetus)、地中海细柱藻(Leptocylindrus mediterraneus)、尖刺伪菱形藻(Pseudonitzschia pungens)、优美施罗藻(Schroederella delicatula)和斯氏几内亚藻(Guinardia striata)等;(3)丰度-生物量曲线(ABC)分析结果显示,当微藻赤潮出现时,数值丰度的K-优势曲线位于生物量K-优势曲线上方,而无赤潮时2条曲线大体上重叠。其模式可指示厦门海区西部海域污染严重以及东-东北部中度污染的状况;(4)根据各航次全部调查数据所作的PCA分析得到的前3个最主要成分,包括浮游植物丰度和溶解氧,铵氮和磷酸盐,盐度和温度等,大约解析本调查总差异的78.5%。

Abstract: 根据1999年夏季(7~8月)我国首次北极科学考察期间“雪龙”号考察船在楚科奇海(66°0.3′~75°18.6′N,153°36.5′~174°59.5′W)和白令海(55°59.8′~66°0.3′N,173°21.1′E~175°53.9′W)49个站采集的样品研究了该区网采浮游植物的分布特征。结果显示,两个调查区的浮游植物多样性指数和均匀度平均值几乎相等且都较低,分别变动在1.88~1.90和0.43~0.45之间。然而,两个区存在明显的空间异质性。就丰富度和种类组成而言,楚科奇海的细胞密度和物种总数量远高于白令海,前者为9122.56×104cells.m-3和103种,而后者为161.78×104cells.m-3和71种。上述生态学指标不同站点间的变异也大。用多元分析方法对浮游植物群聚的分布异质性加以讨论。主成分分析(PCA)结果表明,解析调查区浮游植物分布方差的33.0%的两个最主要成分(即主要物种变量)分别是北极-北方浅海群落(泛北极群落)和北方大洋群落的主要种群。前者包括某些圆心硅藻,如旋链角毛藻(Chaeto-ceroscurvisetus)、柔弱角毛藻(C.debilis)、聚生角毛藻(C.socialis)、叉尖角毛藻(C.furcellatus)等多种寡色体类角毛藻以及冷淡劳德藻(Lauderiaglacialis)、丹麦细柱藻(Leptocylindrusdanicus)、诺登海链藻(Thalassiosiranordenskioldii)和脆杆链藻(Bacteriosirafragilis)等;后者主要有小环毛藻(Corethroncriophilum)、平截鼻状藻(Probosciatruncata)、无刺鼻状藻(P.inermis)、西氏细齿状藻(Denteculaseminae)和一些多色暗角毛类角毛藻,如大西洋角毛藻(Chaetocerosat-lanticus)等。泛北极群落主要分布于楚科奇海南部和中部,而北方大洋群落的主要分布区在白令海调查区的西南部。通过聚类分析还辨认出7个包含不同群落的主要网采浮游植物分布区,但是由于不同水系的不同程度影响,以及极具不确定性的浮冰的位置及其物理状态(聚集、开裂和消融等)也会在短时间内给调查区生物过程导入变异性,从而使得这些分布区的归类复杂化,尤其在楚科奇海。

Abstract: Schistosomiasis japonica remains a significant public-health problem in China. This study evaluated cost-effectiveness of a comprehensive schistosomiasis control program (2003–2006). The comprehensive control program was implemented in Zhangjia and Jianwu (cases); while standard interventions continued in Koutou and Xiajia (controls). Incurred costs were documented and the schistosomiasis comprehensive impact index (SCI) and cost-effectiveness ratio (Comprehensive Control Program Cost/SCI) were applied. In 2003, prevalence of Schistosoma japonicum infection was 11.3% (Zhangjia), 6.7% (Jianwu), 6.5% (Koutou), and 8.0% (Xiajia). In 2006, the comprehensive control program in Zhangjia and Jianwu reduced infection to 1.6% and 0.6%, respectively; while Koutou and Xiajia had a schistosomiasis prevalence of 3.2% and 13.0%, respectively. The year-by-year SCIs in Zhangjia were 0.28, 105.25, and 47.58, with an overall increase in cost-effectiveness ratio of 374.9%–544.8%. The SCIs in Jianwu were 16.21, 52.95, and 149.58, with increase in cost-effectiveness of 226.7%–1,149.4%. Investment in Koutou and Xiajia remained static (US$10,000 unit cost). The comprehensive control program implemented in the two case villages reduced median prevalence of schistosomiasis 8.5-fold. Further, the cost effectiveness ratio demonstrated that the comprehensive control program was 170% (Zhangjia) and 922.7% (Jianwu) more cost-effective. This work clearly shows the improvements in both cost and disease prevention effectiveness that a comprehensive control program-approach has on schistosomiasis infection prevalence.

Abstract: Objective To explore the expression levels of KAI1/CD82 gene in the cell lines of human nasopharyngeal carcinoma(NC) with different metastatic potency,and to determine the expression of KAI1/CD82 proteins in both nontumorous nasopharyngeal tissue and NC.Methods Immunohistochemical technique and Western blot were used to detect the location and expression of KAI1/CD82 protein in 5 cell lines of NC.The expression levels of KAI1/CD82 protein were assessed in 70 NC cases and 30 cases of nontumorous nasopharyngeal tissues by immunohistochemistry.Results Western blotting indicated that the expression level of KAI1/CD82 protein decreased gradually(P < 0.05) with the increased metastatic potentiality.Immunohistochemical detection revealed that KAI1/CD82 was expressed in plasma membrane and/or cytoplasm of NC cells.The expression of KAI1/CD82 protein was lower in NC(44.3%) than in nontumorous nasopharyngeal tissues(70.0%) with significant difference(P < 0.05).4.No correlation existed in the expression level of KAI1/CD82 protein in NC tissues with the following factors: sex,age,pathological type,T stage and other clinical parameters(P > 0.05).The positive expression rate of KAI1/CD82 protein in NC stage of N0,N1,N2 and N3 was 68.4%,43.8%,33.3% and 25%,respectively,and it gradually declined with the progression of N stage.The expression rates were significantly higher(P < 0.05) in the group without lymph node metastasis(N0)(68.4%) than in those groups with lymph node metastasis(N1-3)(35.3%).No significant difference(P > 0.05) was found in the expression rate of KAI1/CD82 protein among the 3 groups with lymph node metastasis(N1,N2,N3).Conclusions KAI1/CD82 gene may play an important role in inhibiting the tumor metastasis.The expression rate of KAI1/CD82 gene is lower in NC tissue than in normal nasopharyngeal tissue,implying that the gene may have played an important role on the development of NC.For NC cases,the expression of KAI1/CD82 protein may be inhibited and the expressive level declines along with NC metastasis and the progression of the N stage,implying that the expression of KAI1/CD82 protein may closely related with metastasis of NC.

Abstract: 利用高精度和稳定的AIRS/Aqua(Atmospheric InfraRed Sounder on board Aqua)数据对SVISSR/FY- 2C(Stretched Visible and Infrared Spin Scan Radiometer onboard FengYun 2C)的两个分裂窗通道IR1(InfraRed 1, 10.9 μm)和IR2(InfraRed 2, 11.9μm)进行交叉辐射定标的方法, 并利用赤道附近2006年12月和2007年12月的AIRS和SVISSR数据完成了交叉辐射定标, 结果表明, SVISSR数据与卷积得到的AIRS数据高度线性相关, SVISSR/FY-2C传感器的两个分裂窗通道不仅存在定标误差, 而且定标误差随时间的变化呈现增大的趋势。相对于AIRS/Aqua测量值, 当SVISSR的通道亮温从220 K变化到340 K时, 2006年12月IR1通道的温度调整量从5.8 K变化到-4.4 K, 而2007年12月IR1通道的温度调整量从6.9 K变化到-5.1 K; 2006年12月IR2通道的温度调整量从2.2 K变化到-1.5 K, 而2007年12月IR2通道的温度调整量从6.3 K变化到-6.1 K。

Abstract: Seventeen foreign ships (including 8 container ships and 9 bulks) entering ports in coast of southeast of China were randomly selected as the monitoring objects. Temperature, salinity, abd plankton species diversity and abundance in the ballast waters were measured. At least 309 taxa from seven plant phyla and five animal phyla were found. The distribution characteristics and survival states of organisms were correlated with the age and salinity of ballast waters. Release of ballast water from ships is a major vector for the introduction of exotic aquatic species. Results of this study indicate that the potential risk for organisms invasion from ballast waters discharged from foreign bulk Carriers harboring in coasts of Southeast China should receive greater attention than those from foreign container vessels.

Abstract: MODIS image is a kind of new and important data for global change research. After analyzing in the depth causes of MODIS data distortion, an optimal method to remove the geometric distortion is developed. The longitude and latitude coordinates, obtained by MODIS sensor, are used to remove the distortion of the 1km resolution MODIS data; For 250m and 500m resolution MODIS data, the same resolution coordinates are calculated by the spline interpolation, then the geometric distortion is removed. Because of the spatial irregularity of MODIS 1B data, a method with forward gridding approach and the inverse gridding approach is utilized to allocate a pixel's position of the geometrically corrected data in the original image. By computing the overlap degree of the current position, the number of the pixels used to calculate the value of the output pixels, the search window sizes and the accurate position of the windows are decided. The value of output pixels is calculated by the distance inverse weight method. All optimal approaches above will improve the processed image's quality and the processing efficiency. The software based on the above approaches is developed in the Visual C 6.0 environment. From the result, the conclusion that the approaches are practical and reasonable can be made.
