里下河并不是一条河,而是一个区域,一片河湖纵横的水乡泽国,也是江苏地势最低洼的地区.rn对于江苏的地域划分有很多种,最简单的一种,便是以长江为界,江之南为苏南,江之北为苏北.作为苏北地区相对独立的地理单元,里下河地区的具体范围是苏北灌溉总渠以南,里运河以东,通扬运河以北,串场河(通榆运河)以西,地图上近似一个“口”字形.涉及扬州、泰州、淮安、盐城、南通等市,总面积约13500平方公里.

目的:研制同型半胱氨酸冰冻人血清国家标准品,用于血清中同型半胱氨酸检测的正确度评价及标准化研究.方法:收集合同型半胱氨酸的外观清澈、无溶血黄疸和乳糜的人血清,经多重滤过及除菌后分装处理,制备成正常(水平Ⅰ)和异常(水平Ⅱ)两水平的标准品,放置于-70℃或以下保存.标准品的均匀性采用单因素方差分析法评估;稳定性采用线性回归分析法评估.选择4家实验室采用同位素稀释质谱参考方法定值,同时评估标准品的不确定度及互通性.结果:共制备了2900套同型半胱氨酸标准品.均匀性评估中,水平Ⅰ和水平Ⅱ的F值分别为1.3749
