Methods Marshland areas near high endemic villages of schistosomiasis in the Poyang Lake region were selected. Corresponding map was digitized and (Landsat 5 TM) the image was corrected according to the digital map. The image where water and land shifted during floody and dry seasons was extracted and classified by unsupervised method. The image in dry seasons was calculated by both Normalized Difference Vegetation Index and Tasseled Cap model. Traditional snail survey was done at the same areas and recorded the geographic position by Geographic Position System. Some cultured lands inside the embankment and water pound in marshland areas were selected as control group. Results The image of pilot areas was classified into 10 classes.

方法选择鄱阳湖区内3个洲岛型血吸病重度流行村周围的洲滩地图进行数字化，在数字化地图的基础上分别对两张Landsat 5TM卫星遥感片进行校正，并提取出冬陆夏水洲滩部分，运用ERDAS IMAGINE软件对此洲滩进行计算机非监督分类、校正植被指数(Normalized Difference Vegetation Index， NDVI)和穗帽湿度变换指数(Tasseled Cap， TC)模型计算；用传统方法进行螺情调查，卫星定位仪记录有钉螺点的经纬度，同时选择部分堤内的农田和水溏作为对照点。

Methods We electronically searched The Cochrane Library (Issue 4, 2009), PubMed (1980 to 2009), Ovid MEDLINE (1950 to 2009), Ovid EBM Database (1991 to 2009), EMbase (1980 to 2009), CBM (1978 to 2009) and CNKI (1979 to 2009) to collect literature about intravertebral analgesia for extern al cephalic version. We screened randomized cont rolled trials according to the predefined inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies, and then performed meta-analyses by using RevMan 5.0.13 software.

计算机检索Cochrane Library （2009年第4期）、PubMed (1980~2009)、Ovid MEDLINE (1950~2009)、Ovid循证医学数据库(1991~2009)、EMbase (1980~2009)、CBM (1978~2009)和CNKI (1979~2009)，按纳入和排除标准筛选椎管内镇痛在外倒转胎位术中应用的随机对照试验，提取资料及评价文献质量后，采用RevMan5.0.13软件对数据进行Meta分析。
