Association study based on population level may find the possible SNP and/or haplotype associated with the disease.

系统地在群体水平上筛查鉴定SNP，特别是编码区和基因调控区的SNP，并通过病例-对照组间的比较和统计学分析，有可能获得与疾病相关联的SNP位点或单倍型。

Our data supported the presence of a gene-dose effect only for haplotype but not for the single polymorphism sites.

总之，我们的结果支持基因剂量效应可能存在于单倍型中，而不与单个位点直接关联。

Patients were not remission or combined with hematolysis, and there was not a donor coincided with human leukocyte antigen matching. If after Bu-CTX2 preconditioning, ciclosporin A plus methopterin schema is used for preventing graft versus host disease, many complications, low success rate or high reoccurrence rate can be detected.

受者为未缓解、合并溶血病例，且无人类白细胞抗原配型相合的血缘供者，如予Bu-CTX2方案预处理，单用环孢素A+甲氨蝶呤方案预防移植物抗宿主病，则面临并发症多、移植成功率低或移植后易复发等难题。

The heterogenicity of mitochondrial DNA has impact on the system performance of the examination system mainly in identifying monoploid of examination samples and calculating the probability of individual recognition.

线粒体DNA异质性的出现，对检测体系的系统效能存在着影响，主要表现在对所检测样本的单倍型的认同及个体识别概率的计算上。

After the platelet transfusion, the antibodies of all the cases of the homotype platelet transfusion were negative, but the antibodies in 2 cases of the control group were positive, and there was antibody to HPA-3a in one of the antibodies positive cases.

血液病人接受单采血小板输注后，HPA-3同型输注组血小板抗体阴性，而对照组有2例存在血小板抗体，其中1例为HPA-3a抗体。

Flooding,as a kind of disturbance events,occurred with higher and higherfrequency over the world.To investigate the effects of flooding disturbance ongrassland vegetation and the soil,a comparatively thorough study was conducted onAneurolepidium chinense grassland in Songnen plain,Northeast China.The studysite was located in Sanjiadian National Rangeland in the territory of Da'an city,Jilirprovince,which was partly flooded in 1998.On the study site,Several transectssubjected to different flooding durations and intensities were designed for thecomparative study among them on such aspects as vegetation characteristics,seedbanks,vegetative propagation of rhizomatous plants,distribution patterns ofpopulations,interspecific relations,and physio-chemical properties of soil.Theresults were as follows:(1)Of the functional group composition of the vegetation,with the elongation of the flooding duration or the increase of flooding severity,theratio of hygric and hygro-mesic plants increase,while that of mesic and mesoxericplants decrease,of Therophytes changed unimodally,of Geophytes increased,whileof Hemicryptophytes decreased.

为弄清草地植被及其土壤环境对水淹干扰的响应，在松嫩平原羊草草地1998年部分遭受水淹的吉林省大安市三家甸子草场内设置了经历不同水淹干扰持续时间和不同水淹强度的样带，并在这些样带之间从植被特征、种子库特征、根茎植物的营养繁殖性能、种群分布格局、种间关系及土壤的理化性质等多个方面展开对比研究，主要结果如下：(1)在植被的功能群组成中，随干扰强度的增加和水淹干扰持续时间的延长，湿生、湿中生类植物功能群的优势度比例基本上是逐渐增加的，中生、中旱生类植物功能群的优势度比例则逐渐减小，而一年生植物的优势度比例呈单峰型变化，地下芽植物比例增加，地面芽植物比例减小。

The boiler is all steel structural ∏ type drum boiler of a subcritical parameter, pump circulation, single reheat, single furnace balance draft, dry slagging and hypaethral placement.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
