Recurrent pregnancy loss (RPL) is a condition with complex etiologies, to which both genetic and environmental factors may contribute. During the last decade, studies indicated that the expression patterns of the prokineticin receptor (PKR1 and PKR2) are closely related to early pregnancy. However, there are few studies on the role of PKR1 and PKR2 in RPL. In this study, we purpose to investigate the association between polymorphisms of the prokineticin receptor (PKR1 rs4627609 and PKR2 rs6053283) and RPL on a group of 93 RPL cases and 169 healthy controls. Genotyping of the single nucleotide polymorphisms (SNPs) was performed using a Sequenom MassARRAY iPLEX system. The results revealed a significant association between PKR2 rs6053283 polymorphism and RPL (P=0.003), whereas no association was observed between PKR1 rs4627609 polymorphism and RPL (P=0.929) in the Chinese Han population.  相似文献   

易地扶贫搬迁群众心理适应困境对策探究     

曹雪梅 《安顺学院学报》2017,19(5)

易地扶贫搬迁是"十三五"期间精准扶贫、脱贫致富的一项重大工程,搬迁群众在心理适应方面或多或少存在着一些问题,单从国家、政府及搬迁群众个人三个角度来看,都存在着封闭心理、排斥心理、抵触心理、不信任心理等困境.结合精准扶贫及易地搬迁相关政策,从国家、政府及搬迁群众个人三个维度来调适存在的心理困境,确保搬迁群众"稳得住"不返迁不另迁、"能致富",实现可持续发展.  相似文献

企业中层培训的误区及对策     

司强  曹振杰 《现代企业教育》2003,(9):26-27

培训理念误区VS对策 在培训的理念上,很多企业片面强调高层培训,严重忽视中层培训.目前我国企业正在兴起培训热潮,不重视培训的企业越来越少.特别是在大中型企业,培训已被提上工作日程,越来越多的企业做出了培训预算,建成了培训体系.这是由于多年的市场竞争洗礼,企业认识到转变观念、接受新知的必要性和迫切性.但是,企业往往将培训预算放在高层管理者培训上,而忽视对中层管理者的正式培训.高层管理者热衷于参加各种总裁(CEO)研讨班、高级论坛、花费颇多.但对中层培训却吝于投资.其原因有三:一是经费限制;二是用管理代替培训,以为只要决策者观念和决策正确,令中层管理者执行即可;三是担心中层管理者技能提高,不安于现状.  相似文献   

家族、生存和人性的悲剧——重评张爱玲的小说《金锁记》   总被引：2，自引：0，他引：2  

曹书文 《河南师范大学学报(哲学社会科学版)》2000,27(3):120-123

《金锁记》自问世以来就受到读者和批评家的普遍关注．人们对作品中主人公曹七巧的评价也逐渐达成了共识,即曹七巧是人性恶的典型,而她对金钱的贪婪是造成其悲剧的主要原因,本文对此说提出质疑,认为曹七巧是一位融人性的普恶美丑于一体且具丰富内蕴的艺术典型。她的悲剧,既是家族制度的悲剧,又是生存和人性的悲剧。  相似文献   

Motilin levels and electrogastroenterogram studies in hypothyroidism     

Wang Hang-yong  Cao Qian  Li You-ming 《浙江大学学报(A卷英文版)》2001,2(4):453-455

To study the relationship between gastrointestinal dysfunction and motilin in patients with hypothyroidism. The plasma motilin concentration was measured by radiommunoassay (RIA) in 30 patients with hypothyroidism and also in 30 controls. At the same time, the electrogastroenterogram was also taken. Among the hypothyroidism patients, 56.6% had decreased gastric motility, especially in gastric body and greater gastric curvature; 86.6% had decreased colonic motility, especially in the left half of the colon. There were no significant differences of plasma motilin concentration between patients with hypothyroidism and controls (P>0.05). There were also no differences between pre-treatment and post-treatment individuals, but significant differences were observed in the electrogastroenterogram. We conclude that the plasma motilin concertration in hypothyroidism patients was the same as that in normal patients, and that electrogastroenterogram studies in patients with gastrointestinal dysfunction may be valuable.  相似文献   

自由能—氧化态图的应用     

曹心德  陈庆榆 《安徽科技学院学报》1991,(2)

自由能—氧化态图是A、A、Frost于1950年首先提出来的,它是以金属单质为基准(△G°=0),在PH=0时各氧化态物质的标准吉布斯自由能(△G°)作为纵坐标,以其相应的氧化态值(N)作为横坐标的曲线图,通常简称为△G°—N图。例如,图一为锰元素的△G°—N图。这一图解对于元素的不同氧化态的水溶液化学性质都能给出明确的半定量的说明。本文在分析图象的基础上,总结规律,归纳该图在无机化学教学中的一些主要应用。  相似文献   

WVD的快速计算     

曹家麟  陈光化 《上海大学学报(英文版)》2003,7(3):265-269

The paper proposes a new method for computation of the Wigner-Ville distribution (WVD) taking account of the conjugate symmetry of the WVD kernel function and the periodicity and symmetry of the trigonometric function. The method transfers the computation of WVD into real field from complex field to remove the redundancies in the fast Fourier transform(FFT) computation. The realization of fast cosine operation and fast sine operation considerably reduces the computation cost. Theoretical analysis shows that  相似文献   

The effect of distributed monitoring exercises and feedback on performance, monitoring accuracy, and self-efficacy     

John L. Nietfeld  Li Cao  Jason W. Osborne 《Metacognition and Learning》2006,1(2):159-179

Monitoring one’s own study processes accurately is important in self-regulated learning. This study compared a treatment (N = 45) and comparison class (N = 39) on the effects of monitoring exercises and feedback on calibration and test performance over a 16-week undergraduate course. Path analyses revealed a significant influence of the intervention on class performance, calibration, and self-efficacy. The results suggest the appropriateness of integrating distributed metacognitive exercises in class content and the fundamental role of monitoring ability in performance-based course outcomes and self-efficacy.  相似文献
