Hirayama disease should be considered for young patient,especially male patient,with asymmetrical amyasthenia and amyotrophy in the hand and forearm.Hirayama disease can be diagnosed if MR abnormalities of the lower cervical dural sac and spinal cord are seen in a fully flexed position.

当遇到青少年出现手及前臂不对称的肌无力和萎缩而无感觉障碍时，应首先考虑有平山病的可能，可进一步行屈颈MR检查，出现下颈髓及其硬膜囊的特征性表现可确诊。

The mice were sacrificed on 7, 10, 14, 21 and 28 days post-inoculation and then the hearts were aseptically removed. Pathological changes in the myocardium were observed by light microscopy and the expression of the CD4+ T lymphocyte in the myocardium was determined by immunohistochemistry. ResultsThe CD4+ T lymphocyte was found in the myocardium in the CVB3 infection group.

分别于接种病毒后第7、10、14、21、28d随机取正常对照组小鼠3只、病毒感染组小鼠8只断髓处死，无菌条件下取心脏，光镜下观察心肌组织的病理变化并计算心肌病理组织学积分，应用免疫组化方法检测CD4+ T细胞在心肌中的表达，并与心肌病理组织学积分作相关性分析。

An analysis of correlation between the expression of MUC1 and other clinic parameters showed that increased MUC1 antigen expression was associated with some poor prognostic factors such as extramedullary infiltration and the age of older than 60-year-old patients with AML.

在AML中MUC1高表达与患者的年龄及髓外浸润呈正相关，而与患者的性别、白细胞计数、乳酸脱氢酶含量及缓解率无明显相关。

These clinical presentation were different from that of chronic inflammatory demyelinating polyneuropathy.

RGBS应属多次发作的典型的急性GBS，每次发作之间无明显相关，与慢性炎症性脱髓鞘性多神经病不同，诊断时需认真鉴别。

The newly discovered endogenous vasodilating and diuretic peptide adrenomedullinwas considered to be of attractive value in clinical treatment of hypertension and congestive heart failure.

为探索通过体内表达肾上腺髓质素(adrenomedullin， AM)治疗高血压和慢性心衰的可能性，本实验构建了重组AM真核表达载体，并在无内源性AM表达的凡62细胞株上进行了体外表达实验。

Methods. Bovine nucleus pulposus cells were serially passaged in the presence or absence of FGF-2 (1 and 10 ng/mL).

研究方法：在有或无FGF-2的条件下，传代培养牛的髓核细胞。

Methods. Boine nucleus pulposus cells were serially passaged in the presence or absence of FGF-2 (1 and 10 ng/mL).

研究方法：在有或无FGF-2的条件下，传代培养牛的髓核细胞。

Fig 1 At the experimental side, two weeks after operation (HE ×100) Many pieces of cartilage cells and spindle-shaped mesenchymal cells were found, by light microscope Fig 2 At the experimental side, twelve weeks after operation (HE ×100) Medullary cavity had formed, which contained hemoblasts and adipocytes, but the trabculae was not typical, by light microscope Fig 3 At the experimental side, twenty-four weeks after operation (HE ×100) The typical cancellous bone had formed, by light microscope Fig 4 At the control side, twenty-four weeks after operation (HE ×100) A large part of CXB was degraded, resorbed and replaced by fibrous tissue, but there was'not any new formed bone, by light mocroscope

图1 实验侧术后2周(HE ×100)镜下可见很多软骨细胞条索和团块生成及大量梭形间充质细胞图2 实验侧术后12周(HE ×100)镜下可见有髓腔形成，内含有造血和脂肪细胞，骨小梁尚不典型图3 实验侧术后24周(HE ×100)镜下可见形成典型的松质骨结构图4 对照侧术后24周(HE ×100)镜下可见大部分CXB被降解吸收，为纤维组织替代，无新骨形成

The thymuses of ZD rats appeared atrophy, with thin cortex, unclear boundary of thymus cortex and mudulla, and decreased thymocytes.

3显微镜下观察，ZD组大鼠胸腺明显萎缩，皮质变薄、疏松，皮、髓质分界模糊，胸腺细胞明显减少，胸腺小体的数量也明显减少。补锌后，ZS组胸腺的病理结构有明显恢复，与ZA〓组无明显差异。

METHODS: Eleven specimens of medulloblastoma were acutely dissociated and triturated into single cells without trypsin digestion.

本研究旨在利用简化的无血清培养基和悬浮培养方法，从人髓母细胞瘤中分离培养脑肿瘤干细胞，观察其在体外的增殖、分化。

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。
