Flow cytometric method to measure urea-resistant alkaline phosphatase from blood neutrophils for use in the prenatal screening of Down's syndrome

The histochemical measurement of urea-resistant alkaline phosphatase from maternal blood neutrophils is known to have a high detection rate for the prenatal detection of Down's syndrome pregnancies. However, because the histochemical method is laborious and subjective to use, it has not gained widespread acceptance in prenatal screening programmes. We present a simple and objective method for the measurement of urea-resistant alkaline phosphatase by flow cytometry. The method should allow the design of larger studies aimed at evaluating the role of neutrophil urea-resistant alkaline phosphatase in the prenatal screening for Down's syndrome.     

Expanding multiple marker screening for Down's syndrome to include Edward'S syndrome

Information on maternal age and maternal serum alpha-fetoprotein, unconjugated oestriol (uE₃), and human chorionic gonadotrophin (hCG) levels was used to investigate retrospectively the effect of estimating Edward's syndrome risk in women having multi-marker screening for Down's syndrome. The screened population comprised 15 pregnancies affected by Edward's syndrome, 15 with Down's syndrome and 5472 unaffected pregnancies. The use of all three markers to estimate Edward's syndrome risk would have led to the detection of 10–12 (67–80 per cent) cases with a false-positive rate of 0.3–0.6 per cent depending on the risk cut-off. A further case would have been detected as a result of screening for Down's syndrome alone. Similar results were obtained when the Edward's syndrome risk was based on uE₃ and hCG only. These data suggest that extending Down's syndrome screening to include Edward's syndrome risk will yield a high detection rate with only a small increase in the false-positive rate.     

关于小于检出限监测结果表示方法的探讨

在环境监测中，在上报结果小于检出限时，以“未检出”、“零”、“无”或“０００…ｎ”等来表示都是不妥当的，会给环境管理和数据使用带来不良影响，甚至会误导出错误的结论。对于此类结果，应以“小于检出限”表示为好。     

环境侵权损害确立的客观基础及事实分类

环境侵权越来越成为我国的一大社会问题。在阐述损害的构成与历史发展的基础上，分析了确立环境损害的客观必然性，同时对环境侵权损害后果作出较为准确的分类。     

全球环境变化与全球不平等南北方的不同立场

全球环境变化给发展中国家和南北关系带来深刻影响，理解环境问题的全球不平等需要以发展中国家80年代开始的经济结构调整和沉重债务为背景。南方的环境政策优先在很大程度上与其生活的可持续性相连，而不是通常与全球环境变化的长期性风险相关，然而，全球环境变化又与发展中国家贫困人口的日常生活紧密相关。从南方的立场看，当“问题”对他们不十分迫切时，就很难同意采取措施，仅此原因，北方对全球环境变化的关切要得到成功回应，真正的全球契约就需要解决基本“发展”问题，主要是贫困。     

功能区排放负荷污染系数百分比分配法研究

在考虑了总量控制区风频、风速和各功能区位置及污染源“影响范围”等影响因素的条件下，提出了“平均下风距离”的概念，从而建立了一种更为科学、合理的总量控制区内功能区排放负荷分配新方法。通过与 总量控制A值法所提出的面积分配方法相比较，验证了新方法的合理性和有效性。
