解剖

Placenta as a key temporary organ for maintaining oxygen and nutritive substance exchange in universe and foetus contained immature embryon and adult stem cells that trended to maturity no matter from anatomic structure or growth, besides, placenta could not be related to ethics.

胎盘作为胚胎发育中维系母体和胎儿氧气及营养物质交换的重要暂时性器官，无论从解剖结构还是在发育行为上，都包含了较为幼稚的胚胎及趋于成熟的成体干细胞成分，而且胎盘不会涉及伦理道德问题，目前已成为寻找人类间充质干细胞新来源及提高临床应用效果的研究热点。

A substantial proportion of early embryo death and miscarriages are caused by chromosomal, anatomical and endocrinological abnormalities, up to 40% of fetal losses remain a consequence of unexplained aetiology.

有一定比例的早期胚胎死亡与胚胎染色体畸变、性器官解剖病变及母体内分泌紊乱有关，但是超过40%的早期胚胎死亡原因不明。

Anatomical studies of femoral endosteal geometry suggest that exact fit of a prosthesis within the cortex is implausible because of large ariations in anatomy and age-related changes in the diameter of the canal.

对股骨髓腔几何形状的解剖学研究表明，由于髓腔的解剖变异相当大并且其直径随年龄而发生改变，故要达到假体与骨皮质完全密贴是不太可能的。

Diplopia and disturbance of ocular movement are related to the incarceration of the extraocular muscles and the displacement of orbital wall, and the management is simple relatively. However, the treatment of enophthalmos is difficult because the orbital reconstruction is made to be complicated by the complex morphous of orbital wall and the limited operative area. This study introduced the use of CAD/CAM technique in orbital reconstruction, and the result is more satisfactory than traditional methods.

眶壁重建是其矫治的首要条件，然而，眶壁形态复杂，并有视神经由眶尖通过，加之术野受限，使精确的解剖复位很难完成，本文应用CAD/CAM技术，术前成型钛网并行眶壁重建，通过CT分析和眼科检查，证实该技术在眶壁重建的精确性上均较传统方法有明显提高，其中，眶内壁的修复程度和眶底修复形态的对称性，以及眶容积缩小程度反映了其形态修复的精确性，而置入深度则体现了在缺损修复范围设计中的优越性。

Nevertheless, even if the affected bowel loops at the abnormal anatomic location are not dilated and small internal hernias with low-grade obstruction are detected, we recommend that surgical colleagues use appropriate care to decrease hernial strangulation. Examples of such care include carefully monitoring the patient's vital signs and physical examination results or performing follow-up CT or gastrointestinal studies enhanced with intraluminal contrast material, including CT enteroclysis.

尽管处于异常解剖部位的受累肠管没有扩张，腹内疝较小，梗阻程度较轻，我们也推荐外科同事给予适当的护理减小疝性绞窄，例如详细的监护病人生命体征、进行体格检查、复查CT、使用管腔内造影剂的胃肠增强检查，包括CT肠造影术。

When any impairment occurs, the barrier can no longer exist and may result in enterogenous infection and multiple system organ failure and the burn patient may be in a serious state.

结果：完整的胃肠粘膜屏障应包括胃肠道完整的解剖结构，正常的生物菌群和健全的免疫功能，一方受到损害，胃肠屏障即不存在，直接后果是肠源性感染和多脏器功能不全综合征的发生，烧伤旋即进入持续性危重状态。

Interestingly, AQP4 distribution in glial cells and ependymal cells showed certain directivity, but the former was mainly in the membrane side contacting with capillary endothelial cells and the latter mostly in the basolateral membrane of ependymal cells.

AQP4在正常兔脊髓内具有广泛的表达，其表达的解剖定位提示AQP4在脊髓内主要参与水分子的转运及平衡调节、电解质代谢，并受局部调节以适应特殊的功能需求。

The anatomic location, gross desc ription and photos uploaded so far of the tumor are consistent with ependymoma, but I have to point out that the quality of photos is suboptimal and insufficient for rendering a definite diagnosis.

这个肿瘤的解剖位置、大体描述以及目前上传上来的照片符合室管膜瘤。但是我不得不指出照片的质量并不理想，不足以得出一个明确的诊断。

Histological characteristics of reproductive gland,were described and its relations to the cantharidin stored and transferred within or between the adults were discussed. Epicauta mannerheimi ; Mylabris phalerata ; reproductive gland ; histological characteristics ; cantharidin

作者在进行两种芫菁生殖腺解剖后，又初步探究大斑芫菁生殖腺的组织学特征，目的在于为芫菁的精子贮存、运送、授精、芫菁素传递等过程提供初步理论依据。1 材料和方法1 。1 材料细纹豆芫菁于 1 999年 6月中旬采自福州市郊高

The salty gland of Messerschmidia sibirica is developed from epidermic cell of stem and leaf.

利用石蜡切片法研究了砂引草茎叶的解剖结构，尤其是对泌盐腺的位置、泌盐腺的形态结构及泌盐腺的发生发育过程进行了系统的研究，结果表明：砂引草茎的初生结构维管束是外韧的，且其有10-12束，大小不等，髓和髓射线发达；叶的上下表皮细胞各一层，栅栏组织与海绵组织分化明显。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
