异常发育

An otherwise healthy 12-month-old girl presented for evaluation of reduced abduction of the left eye detected at 6 months of age. The remainder of the examination was unremarkable. A special MRI sequence-fast imaging employing steady-state acquisition-visualized the right but not the left sixth nerve cisternal segment. This is the first reported use of the MRI FIESTA sequence to diagnose aplasia of the sixth cranial nerve.

应用快速平衡稳态取像核磁技术检测第六颅神经发育不全：本研究首次报道利用 MRI FIESTA 诊断第六颅神经发育不全，一例12个月的婴儿其他各项指标正常，在6个月时发现左眼诱导注视减少，其他的检查未见明显异常，利用 MRI FIESTA 可检测到右侧第六颅神经，但左侧部分检测不到。

Hypohidrosis ectodermal dysplasia is a rare congenital disorder that results in abnormalities in the structures of ectodermal origin tissues, such as teeth, eccrine sweat glands, hair and nails.

少汗型外胚层发育不良症是一种罕见的起源于外胚层组织，如牙、汗腺、毛发等发育异常的遗传性疾病。

The growth growth high peak period that corrected and cured to contribute to make use of a kid in early days stopped excrescent growth growth trend and led to it is as usual.

早期矫治有助于利用孩子的生长发育高峰期阻断异常的生长发育趋势，将其导向正常。

1Unequal number of univalents with decreased degree of synapsis and lagging chromosomes occurred in meiosis.The abnormal chromosomal behavior correlated with heterogenicity gave rise to unequal allocation of homogenous chromosomes to daughter cells and resulted in the deletion of functional chromosoms,thus led to the occurence of a certion proportion of aborted pollens.(2)The interaction between genetic imbalance and such environmental factors as temperature,etc.,further drew forth physiological and even structrural imbalance,with abnormal development of pollen mother cells and tapetal cells,and consequently resulted in no or very few production of pollens.The difference in the interaction between environment and genotype reflected on the unstability of pollen abortion in different years.

1在减数分裂中有数目不等的联合程度较差的单价体以及落后染色体出现，这种与异质性相关的染色体行为异常，导致同源染色体向子细胞的不均衡分配，造成具功能染色体的缺失，从而引起毛白杨一定比率的败育花粉的产生；(2)遗传上的不平衡与温度等环境因子相互作用，进一步引发毛白杨生理乃至结构上的不平衡，花粉母细胞和绒毡层细胞发育异常，从而造成不产粉或产粉较少；环境与基因型互作的差异性导致了花粉败育的年度不稳定性。

We believe that these lesions overlap histomorphologically with higher-grade dysplastic nevi and de novo intraepidermal epithelioid melanocytic dysplasia.

我们认为，这些病变与分级较高的发育异常痣和新生表皮内上皮样黑色素细胞发育不良存在着组织形态学的重叠。

Among them,27babies were well developed,but23were hypogenetic,with abnormal blood flow,point out intrauterine growth retardation.

另50例胎儿出生时体重小于2500g，其中27例新生儿虽体重较正常儿偏小，但发育正常；另23例胎儿血流动力学指标异常，提示胎儿宫内窘迫，导致异常分娩，新生儿生存率低。

The average weight of the other group of50fetus-es is less than2500g when they were born.Among them,27babies were well developed,but23were hypogenetic,with abnormal blood flow,point out intrauterine growth retardation.

The cause of macromastia is not well understood and may be related to the mistakes in gene expression during puberty or pregnancy. There are a lot of researches focusing on the molecular mechanism of breast cancer and lactation, but seldom on macromastia. The size of an organ is determined by the size of the cells and the number of the cells, which depends on cell division and cell death.

巨乳症的成因可能是由於青春期或怀孕期乳房发育基因的表现异常而造成，但目前的研究对此并没有很详细的研究，与巨乳症相关的研究大多集中於病患的心理生理评估及手术方法的比较，乳房发育的相关研究目前都集中於乳癌与泌乳退乳的机制。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
