多型性

In SCD survivors, sustained monomorphic ventricular tachycardia is inducible by electrophysiologic testing in 40 to 50% and polymorphic VT in 10 to 20%; in 30 to 50%,no sustained arryhthmia is induced.

在心源性猝死生还者中， 40~50%电生理试验能诱导持续单一型室性心动过速，10~20%能诱导多型的，30~50%不能诱导持续的节律异常。

Sensitiity and specificity were 73%(95% CI 60-86) and 91%(79-100) for neuromyelitis optica and 58%(30-86) and 100%(66-100) for optic-spinal multiple sclerosis. NMO-IgG was detected in half of patients with high-risk syndromes.

视神经脊髓炎的敏感性和特异性分别为73%和91%，视神经-脊髓型多法性硬化的敏感性和特异性则分别为58%和100%。

Objective: To study the clinical characteristics and treatment of the patients with pleomorphic xanthoastrocytoma.

目的：探讨多形性黄色瘤型星形细胞瘤患者的临床特征及治疗。

Methods: The clinical data of 8 patients with pleomorphic xanthoastrocytoma were retrospectively analyzed.

回顾8例多形性黄色瘤型星形细胞瘤患者的临床资料。

Polymorphism includes data referencing and sharing, program matching and linking and code resuing etc.

笔者认为，多态性是指程序中同一个语法单位，可以有多种语义、诱发多种型态。

The qualitative and quantitative analysis of schizophrenia and single nucleotide polymorphism of catechol-O-methyltransferase , Proline Dehydrogenase and DYSBINDIN genes were done by using transmission disequilibrium test . Results:(1) The symptoms of first-episode schizophrenia were divided into four independent symptom dimensions: psychomotor poverty, reality distortion, disorganisation and depression-anxiety.

4采用传递不平衡检验、单倍型传递不平衡检验和定量性状传递不平衡检验的方法对6号、22号染色体上3个候选基因，即儿茶酚氧位甲基转移酶(catechol-O-methyltransferase，COMT)、脯氨酸脱氢酶(Proline Dehydrogenase，PRODH)和DYSBINDIN基因的9个单核苷酸多态性(single nucleotide polymorphism，SNP)位点与精神分裂症、神经认知功能、人格特质和临床症状表现的关系进行了定性和定量的遗传学分析。

In this study we mapped a grain length controlling gene named Lk-4 with SSR and CAPs markers by screening 800 recessive plants in a BC2F2 population derived from a cross of Shuhui527×Xiaoli and backcrossed with Xiaoli as the donor parent.

对F2和BC2F2 群体籽粒大小形状和千粒重的遗传分析表明，回交能将大部分对目的基因效应具有干扰修饰作用的微效基因多态性除去，从而有利于对目的基因型的准确鉴定；在F2和BC2F2群体中只发现两类籽粒长短表现型，即短粒和长粒，并且二者分离比例符合3：1的典型一对等位基因分离比例。

The results showed that NaN3 had great effects on TCL growth. Some TCL after treatment got white or browning and died and grew slowly, and the number of regenerated plantlets was reduced, and the regenerated plantlets became abnormal with leaves crimpled and thicker. The RAPD reaction with 10 primers indicated that the molecule maps of RAPD had some polymorphisms which meant the sequence of DNA was changed.

结果表明，NaN3对类原球茎薄切片生长产生重要影响，部分薄切片白化或褐化死亡，再生类原球茎生长受到抑制，再生苗数量减少，部分再生苗畸变，叶片皱缩、变厚。10条RAPD引物的PCR检测发现，再生苗DNA序列发生了一定程度的变异，产生RAPD图谱带型多态性。

In the experiment ,a study on the polymorphisms of the 62bp of Prepro-orexin gene in ten breeds including Erhualian, Large White and Landrance × Large White × Erhualian crossbreeds was performed by mean of PCR-SSCP and PCR-RFLP.The litter size and growth performance between different genotype of some breeds were analysized.

本实验用PCR-SSCP和PCR-RFLP两种方法在二花脸、大约克及长·杂种猪等十个猪群内进行了Prepro-orexin基因第62bp位点处的多态性的检测，并且分析各基因型与繁殖性状、生长性状之间的相关性。

Methods A PCR-based RFLP procedure was employed to detect the genotypes of 168 family trios of Han descent population in the North of China.

采用PCR技术和限制性内切酶片段长度多态性的方法，检测中国北方汉族168个核心家系的基因型。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
