Prenatal ultrasound diagnosis of Toriello–Carey syndrome

Toriello–Carey syndrome is a rare malformative complex, described for the first time in 1988, characterized by agenesis of the corpus callosum, facial anomalies, cardiac defects and hypotonia. Relatively few neonatal cases have been reported. We describe here the first prenatal ultrasound diagnosis of the syndrome based on the detection of agenesis of the corpus callosum and spongious cardiomyopathy in a 22-week-old fetus of a couple with positive family history. The first sib of the couple was diagnosed with Toriello–Carey syndrome at 1 year of age, and had, in addition to the typical facial anomalies not detectable by ultrasound, agenesis of the corpus callosum and the same heart lesion (spongious cardiomyopathy). This report demonstrates that prenatal diagnosis of Toriello–Carey syndrome is feasible in the second trimester of pregnancy. Copyright © 2002 John Wiley & Sons, Ltd.     

Fe0/厌氧微生物联合体系处理2,4,6-三氯酚影响因素的研究

利用Fe⁰/厌氧微生物联合体系对2,4,6-三氯酚(2,4,6-TCP)进行降解研究。结果表明，Fe0/厌氧微生物联合体系可以有效降解2,4,6-TCP，Fe⁰与厌氧微生物之间存在明显的协同效应。Fe⁰/厌氧微生物联合体系处理2,4,6-TCP的最优条件为：微生物接种量0.434 g VSS/L，Fe⁰投加量15 g/L，体系初始pH值7.0～8.0。

Prenatal diagnosis of congenital cystic adenomatoid malformation of the lung by fetal lung biopsy

A case of type III congenital cystic adenomatoid malformation of the lung was successfully diagnosed prenatally by fetal lung biopsy. We performed this procedure at 22 weeks of gestation, using a biopsy gun system under ultrasound guidance. The pregnancy was undisturbed by the procedure but as the condition was incompatible with life, an abortion was performed. The diagnosis was confirmed at post-mortem examination. Fetal lung biopsy appears to be a useful method for prenatal diagnosis of fetal lung disorders.     

三峡工程与长江中游沿江产业带建设

讨论了长江中游沿江产业带发展条件、限制因素和未来发展，指出三峡工程的建设将对长江中游产业的布局和经济发展带来深刻的变化；防洪作用促进中游两岸大型工业项目的兴建，调整现有沿江城镇的布局，使之结构趋于合理化；电力供应经解能源的紧张状态，改善航运条件，发挥长江黄金水道的综合效益。当然，由于坝下河道冲刷，对现有的码头带来一定的影响，由于冬季水位抬升引起两岸低湖田地下水位上升，加剧两岸土壤潜育化和沼泽化。     

2002年3-6月国内安全事故数据

统计了2002年3-6月国内发生的各种安全事故871起,包括矿业事故、交通事故、爆炸事故、火灾、毒物泄露和中毒及其他事故.统计表明,在这些事故中,矿业事故最多,占61. 8%,平均每天4.5起事故,其次是交通事故(16.3%)、爆炸事故(6.7%)、火灾(6.0%)、其他事故(5.6%)、毒物泄露和中毒(3.7%).871起事故共死亡2 197人,伤3 321人,死亡人数的百分比分别为矿业事故53.7%、交通事故28.0%、火灾6.1%、爆炸事故5.9%、其他事故5.1%、泄露中毒1.2%;受伤人数的百分比分别为泄露中毒37.4%、交通事故26.9%、爆炸事故14.2%、矿业事故11.8%、其他事故5.3%、火灾4.4%.     

Effect of Climatic Factors on the Growth of Representatives of the Genus Pinus (Pinaceae) under Conditions of Introduction

Four introduced and one aboriginal species of the genus Pinus L. have been studied in the middle taiga subzone of southern Karelia. Significant interspecific differences in the dates of onset, cessation, and peak of the growth of shoots and needles have been revealed. It has been shown that their annual increment depends on the rate of growth, rather than on its duration. The dynamics of shoot and needle growth in introduced and aboriginal species, though largely similar, differ in some respects. These differences reflect species-specific responses to hydrothermal conditions in a certain growing season.

南水北调的资源、环境和社会效应

建设南水北调工程，对中国的水资源在地区间进行合理调配，将带动其他资源的合理配置与利用，还可改善环境，是社会发展的需要，又受社会条件制约，一旦突破建成，将促使社会生产力发生新的飞跃并持续发展。     

湖北省雨涝灾害的风险评估与区划

随着我国灾害科学研究的不断深入及经济建设的日益发展，从风险角度分析灾害已成为灾害分析的一种新视角，它有助于决策者进行灾害管理和制定减灾策略时有针对性地选择最优技术政策，防患于末然。雨涝灾害是湖北省最严重的气象灾害之一，据统计，湖北省平均每年受雨涝危害的农田面积为80．62万hm^2，成灾面积为47．07万hm^2，特别是20世纪80年代以来湖北省工农业生产重地江汉平原和鄂东雨涝事件明显增多，严重威胁和制约着我省国民经济持续稳定发展。依据自然灾害风险分析原理，在分析湖北省雨涝灾害孕灾环境、致灾因子、承灾体密度和经济发展水平及承灾体的抗灾能力的基础上，综合评价了湖北省雨涝灾害风险程度的地域差异，以能综合体现风险程度的风险指数作为指标，将湖北省雨涝灾害分为极重度、重度、中度和轻度四个风险区，并提出了相应的对策措施，为有关部门灾害管理和减灾决策制定提供了参考依据。
