目的分析Prader—Willi综合征（PWS）患儿的临床特征及分子诊断方法，以提高儿科医师对本病的认识。方法收集白求恩国际和平医院新生儿科存在肌张力低、喂养困难，生长发育过程中不明原因的发育延迟、身材矮小、肥胖等特征怀疑为PWS的4例患儿，采用临床结合多重连接探针扩增技术（MLPA）对P245和ME028进行序贯检测。结果共送检4例，其中婴幼儿期3例，新生儿期1例；男2例，女2例；以运动发育迟缓为主要表现2例，以出生后哭声差为主要表现1例，以走路不稳为主要表现11例；检测出缺失型患儿3例，另1例临床疑似患儿经ME028检测阴性。结论新生儿期无明显诱因存在喂养困难、肌张力低等表现，发育过程中有不同程度的运动智力发育落后表现的婴幼儿需考虑PWS，进一步通过MLPA检测P245结合临床辨析及ME028补充检测，可以实现该病的快速诊断，对PWS的临床诊疗有积极意义。

Adsorption of acetanilide herbicides on soil and its components Ⅱ. Adsorption and catalytic hydrolysis of diethatyl-ethyl on saturated Na^+-, K^+-, Ca^(2+)-, and Mg^(2+)- montmorillonite

Journal of Environmental Sciences 2001年第2期13卷 137-142页

作者： liu wei ping 1, fang Zhuo 2, liu Hui jun 1, YANG wei chun 1(1.Institute of Environmental Science, Zhejiang University at Yuquan Campus, Hangzhou 310027, China. E mail: wpliu@*** 2.Institute of Industry Environmental Design, Zhejiang P

Adsorption and catalytic hydrolysis of the herbicide diethatyl ethyl [N chloroacetyl N (2,6 diethylphenyl)glycine ethyl ester] on homoionic Na + , K + , Ca 2+ , and Mg 2+ montmorillonite clays were investigated in water solution. The Freundlich adsorption coefficient, K f, got from isotherms on clay followed the order of Na +≈K +>Mg 2+ ≈Ca 2+ . Analysis of FT IR spectra of diethatyl ethyl adsorbed on clay suggests probable bonding at the carboxyl and amide carbonyl groups of the herbicide. The rate of herbicide hydrolysis in homoionic clay suspensions followed the same order as that for adsorption, indicating that adsorption may have preceded and thus caused hydrolysis. Preliminary product identification showed that hydrolysis occurred via nucleophilic substitution at the carboxyl carbon, causing the cleavage of the ester bond and formation of diethatyl and its dechlorinated derivative, and at the amide carbon, yielding an ethyl ester derivative and its acid. These pathways also suggest that hydrolysis of diethatyl ethyl was catalyzed by adsorption on the clay surface.

利用南北地震带2014-2017年期间的流动重力观测资料,系统分析了区域重力场变化及其与2017年8月8日四川九寨沟7.0级地震发生的关系.结果表明:①区域重力场异常变化与北西西向塔藏断裂和南北向岷江断裂带在空间上关系密切,反映了沿控震断裂在2013-2017年期间发生了引起地表重力变化效应的地壳变形和构造活动.②九寨沟地震前,测区内出现了大空间范围的区域性重力异常,而震源区附近产生了局部重力异常,沿塔藏断裂带形成了重力变化高梯度带,其中,甘肃玛曲、迭部、青海河南蒙古族自治县、四川若尔盖、九寨沟一带重力差异变化达100×10^(-8)m·s^(-2)以上;这些可能反映九寨沟地震前,区域及震源区附近均产生与该地震孕育、发生有关的构造运动或应力增强作用.③九寨沟地震震中位于重力差异运动剧烈的鞍部等值线附近,与断裂走向基本一致的重力变化高梯度带零值线上,这一观测事实进一步佐证了重力场动态变化图像对强震地点预测具有重要的指示意义.

Studying molecular recognition in aqueous environments is crucial for understanding biological processes. Herein, we present a series of N-doped endo-functionalized anthracene-based cavities by introducing inward-directed pyridine units. The subtle modifications can significantly affect the binding properties of these receptors, which is similar to the mutations in biological systems. Combining theoretical calculations and molecular recognition experiments demonstrated that these “mutations” have an impact on the hydrophobicity and charge distribution of the hosts, consequently significantly influencing molecular *** is crucial for understanding the intricate mechanisms of molecular-level interactions in biological receptors.
