Histologically,the resected tumor was composed of epithelioid cells,without vascular or lipomatous component,and was characterized by HMB45 positive on immunohistochemistry.

组织学上由单一上皮样细胞构成，不含血管及脂肪成分，免疫组化呈特征性黑色素生成（HMB-45）阳性。

If a child suffered from precocious puberty or gelasmus epilepsy,together with CT and MRI characteristics of the mass near the tuber cinereum or mammillary body,the diagnosis of hypothalamic hamartoma might be considered first.

如患儿临床上表现为性早熟和痴笑样癫痫，影像学上显示灰结节或乳头体肿块，具有典型CT和MRI表现，应首先考虑本病。

All the study subjects had known colonic disease (a history of colorectal cancer or adenomatous polyps, ulcerative colitis, or positive radiographic findings) or were suspected to have it based on signs and symptoms such as rectal bleeding, hematochezia, melena, or positive fecal occult blood test.

所有受试者都患有结肠疾病（结直肠癌，腺样息肉，溃疡性结肠炎或影像学阳性发现），或根据症状和体征（如直肠出血，便血，黑便，或者大便潜血阳性），疑似患有上述疾病。

The atomic architecture of a spine, from the fibril-forming segment GNNQQNY of the yeast prion protein Sup35, was recently revealed by X-ray microcrystallography.

最近通过X射线微晶学揭示了淀粉样原纤维的原子构造核心：从原纤维形成酵母prion蛋白质Sup35的GNNQQNY片段。

DST showed that the pretreatment with dexamethasone can not repress the total number of CRF immunoreactive neurons in the rat model induced by CUMS, by contrast with a normal repression in the number of CRF neurons in rat induced by acute stress. In brief, the rat model induced by CUMS represented decreased body weight, obvious depression-like behavior, hyperactivity in HPA axis and nonsuppression on the DST, which fits the criteria and neurobiological feature of depression.

简而言之，CUMS诱导的大鼠模型有典型的抑郁症样行为和表现、HPA轴活性升高、DST的失抑制，符合抑郁症模型的行为学标准和主要神经生物学特征，是抑郁症稳定可靠的模型，也是研究应激诱导的糖皮质激素升高所带来的神经生物学效应的良好模型。

DH level, CD4+ T lymphocyte count below 100 × 106/L, and interstitial pneumonia or ground-glass shadow in chest images, the diagnosis of PCP could be made presumptively. It is difficult to make a nosogenic diagnosis of PCP, but TBB considerably increases the positive rate of pneumocystis. Compound sulfamethoxazole is recommended as the first selected drug. In severe cases, corticosteroid and assisted mechanical ventilation combined with compound sulfamethoxazole could remarkably improve the prognosis of PCP.

当AIDS患者出现发热、咳嗽、呼吸困难、低氧血症、LDH增高及CD4+T淋巴细胞＜100×106/L时，结合胸部影像间质性肺炎或磨砂玻璃样改变，临床需考虑PCP；病原学诊断困难，但TBB肺孢子菌检出率高；治疗首选SMZ-TMP，重症病例辅以糖皮质激素和机械辅助通气可改善预后。

Results :Osteoblastoma may present stori form and angiomalike changes besides the classical histological feature.

骨母细胞瘤除出现经典的组织学特征外，尚可出现车辐状排列及血管瘤样变化。

Objective To improve MR Imagine diagnoses of Ovarial Tumor -like lesion and clinic diagnostic value.

目的：提高MR对卵巢瘤样病变影像学诊断的认识及其临床诊断价值。

Bacteriological examination, Pasteurellosis dye concentration polarization can be detected in the bacteria, but this disease can be detected in a similar kind of Brevibacterium sp.

细菌学检查，巴氏杆菌病可检出两极浓染的杆菌，而本病可检出类似球菌样的短杆菌。

Petrographically,the CaO content in ash and the magnetive petrographic characteristics of coal samples were analyzed.

利用煤岩学的理论和方法，对煤灰分中氧化钙含量与煤样煤岩特征的关系进行了探讨。

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。
