Methods The clinical data of 35 patients（69 eyes）with ROP in zone one who diagnosed by examination of indirect ophthalmoscopy were retrospectively analyzed.

所有患儿均经过间接检眼镜检查确诊，根据病变在视网膜的位置分为前部1区和后部1区，分别为49、20只眼。69只眼中急进性ROP12只眼，前部1区4只眼，后部1区8只眼。

In this experiment, effects of local electrolytic lesion of bilateral anteventral or posterior or antedorsal hippocampus on learning and memory of dark avoidance behavior in rats were observed respectively. The results show that local lesion of different part of hippocampus more or less block rat's learning and memory of this behovioral pattern, particularly anteventral lesion, but their instinct of light avoidance and liking dark is not influenced.

本实验分别观察了局部电解损伤双侧海马的腹前部、后部和背前部对大白鼠避暗行为的学习和记忆的影响，结果表明：局部损伤海马各部可以不同程度地阻碍这种行为模式的学习和记忆，其中以损伤腹前部最为严重，依次是损伤后部和背前部，但是对大白鼠避光嗜暗的本能没有影响。

One line from inferior edge of anteroinferior iliac spine to the crossing point of posterior gluteal line and posterior iliac crest was defined as A line, which was parallel to the Chiotic line (the crossing point of Chiotic line and posterior iliac crest called CLIC point).

设定髂前下棘下缘向后经过臀后线与骼嵴后部交叉点的连线截面为A线截面，此线与Chiotic线平行（Chiotic线与髂嵴后部交叉点称为CLIC点）。

The posterior cingulated gyrus of patients with Alzheimers disease is impaired and the extent of damage should has a strong correlation with rCMRglc. The selective impairment might reflect the cortico-cortical and cortico-subcortical disconnections in the pathomechanism of Alzheimer's disease. DTI technique should be used to monitor the disease progression and as a surrogate marker for evaluation of drug efficacy in vivo.

AD患者表现为扣带回后部各向异性损害，且损害程度与葡萄糖代谢率呈负相关；这种损害反应了AD病理机制中皮质－皮质及皮质－皮质下联系的丢失；扣带回后部FA、MD值可以用来监测疾病的进展情况及评价AD治疗药物的临床疗效。

Objective In order to provide early valuable information in diagnosis, prediction and treatment, the ratio between the expansion of orbital volume behind the axis of the globe and the degree of the enophthalmos was studied,and the time and degree of enophthalmos were observed.

目的：通过测量眼眶爆裂性骨折伴有眼眶扩大患者的后部眼眶容积、观察眼球内陷出现的时间及程度，研究后部眶容积扩大与眼球内陷的关系比值，为病情预测和眶内填充手术提供比较精确的参考数据。

Conclution Enophthalmos usually appeared in the second and third week, and it tended to steady until the third month. The ratio is 1.0 between the expansion of the orbital volume behind the axis of the globe and the degree of enophthalmos. The ratio measurement may predict the occurrence and the final degree of the enophthalmos , may provide precise parameter for implant's volume . It has very important clinical significance.

眼球内陷通常于伤后2周～3周出现，3个月时趋向稳定；后部眶容积增大与眼球内陷产生比值为1.0，呈正相关；后部眶容积扩大与眼球内陷比值可预测发生眼球内陷的可能性和程度，为手术矫正眼球内陷提供可靠、精确的参考，具有十分重要的临床指导意义。

Methods 96 cases were devied into early stage group (60 cases, within three weeks )and later period group(36 cases, over three weeks).In early stage group, the time and degree of enophthalmos were observed. In later period group, the orbital volume behind the axis of the globe and degree of the enophthalmos were measured. The relation between the changes of orbital volume behind the axis of the globe and the degree of the enophthalmos was assessed by using Pearson correlation coefficients.

将96例患者按发病时间分为早期病例组（60例、受伤时间1周以内）和晚期病例组（36例、受伤时间3个月以上），早期组除进行后部眼眶容积测量外，分别于1周、2周、3周测定眼球突出度（相差＞1mm为阳性），记录眼球内陷出现时间，用卡方检验进行统计学分析；晚期组测量后部眶容积增大值和眼球内陷量，对其相关性采用Pearson统计方法进行统计学分析，并得出回归方程及相关系数。

Results In early stage group, 5 of 60 cases appeared enophthalmos in first week(8.33%), 48(80%)cases appeared in second week, 53(88.33%)cases appeared in third week. No significant difference was found in second week and third week（χ2＝1.563, P＜0.001. There were significant difference between the first week and second week（χ2＝62.484,P＜0.001 ,the first week and third week（χ2＝76.885,P＜0.001）. There was significant linear correlation between expansion of the orbital volume behind the axis of the globe and the degree of enophthalmos（r=0.994,P＜0.001,with each 1.0ml expansion in the orbital volume behind the axis of the globe causing approximately 1.0mm enophthalmos.

结果：早期组60例患者中，5（8.33%）例患者在1周内出现眼球内陷，48（80%）例在2周内出现内陷， 3周时有53（88.33%）例呈现出内陷；2周时出现眼球内陷的例数与1周时有显著性差异（χ2＝62.484， P＜0.001），2周时出现眼球内陷例数与3周时无差异（χ2＝1.563， P＞0.05），1周时出现眼球内陷例数与3周时有显著差异（χ2＝76.885，P＜0.001），后部眶容积增大与眼球内陷的比值约为1.0，两者之间呈正相关（r=0.994，P＜0.001），即后部眶容积每增加1ml，产生1.0mm的眼球内陷。

Although classic neuroimaging features of RPLS with involvement of the posterior head regions are easily recognized, features that may generally be regarded as atypical were often present in our patients, such as significant anterior involvement, cortical lesions, recurrent RPLS episodes, foci of permanent injury, hemorrhage into lesions, and unilaterality (Figure 1). High signal intensity on T2-weighted image lesions can occur in regions other than the parieto-occipital areas, frequently involving the frontal lobes, basal ganglia, thalami, or brainstem.

可逆性后部白质脑病综合征典型的神经影像学表现为大脑后部受累，尽管这一点很早就被公认；但可逆性后部白质脑病综合征不典型的神经影像学表现，在本文的患者中则更常见，如：大脑前部明显受累、皮层出现病灶、可逆性后部白质脑病综合征再次发作、脑永久性损伤灶形成、病灶内出血、仅见单侧病灶（图1）；T2像常可于额叶、基底节区、丘脑、脑干等顶-枕叶以外的区域见高信号病灶。

It suggests that the horizontal momentum of the meso-cyclone was brought down to the surface by heavy rain. At the right edge of meso-cyclone the momentum and RIF have the same direction, the two airflows overlay together and make the wind increase, so damage wind occurred.

分析认为，弓状回波后部存在较强后部下沉入流，由于强降水的拖曳作用，将中层中气旋的水平动量带到地面，中气旋右侧动量的方向与弓状回波后部的强下沉入流方向一致，两者叠加，使地面风速加大，造成灾害性大风。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
