METHODS: Fourteen patients proved pathologically as brain abscess and 17 cystic/necrotic metastatic tumor underwent conventional MRI and DWI examinations. DWI signal and ADC value were evaluated in cerebritis stage, capsule formation stage, and evolution stage of brain abscess and compared with those of cystic/necrotic metastatic tumor.

病理及临床证实脑脓肿14例，坏死囊变脑转移瘤17例，经常规磁共振检查及弥散加权检查，在脑脓肿脑炎期、包膜期及吸收期进行弥散信号及ADC值的测量，并与坏死囊变脑转移瘤相比较，统计学分析采用χ2检验和t检验。

Human melanoma A375 cells express Cox-2 protein and MMP-1 protein. Celecoxib may be a potential chemotherapeutics for the proliferation of melanoma.

人黑素瘤A375细胞表达Cox-2蛋白和MMP-1蛋白，Celecoxib是一种有潜力的抑制黑素瘤增殖的药物。

This head CT scan demonstrates a mass with irregular margins in the region of the sella. Such a mass may impinge upon the optic chiasm, just like a pituitary adenoma.

头颅CT显示颅咽管瘤，在蝶鞍可见边缘不规则的大肿块，象垂体腺瘤一样压迫视交叉。

Symptoms inquring,nasal respiratory,X ray,CTand MRI images were no valuable for the diagosis of chondroma.Their diagnosis was made based on pathohistology.The chondroma were often damaged in the most of the cases.Suryery is an effective method on chondroma.

鼻窦鼻咽部软骨瘤病因不明，多数学者认为可能是来源于异位的软骨胚芽及头颅软骨遗基的残余，如果只靠症状及鼻腔检查、X线摄片、 CT及MRI扫描一般不能诊断本病，病理是诊断软骨瘤的金指标，治疗则以手术为主。

Quantitative chromatics analysis of large bowel tumorous adenoma and adenocarci-noma was made by the methods of computer image processing.

本文通过对大肠腺瘤和腺癌组织进行计算机图像定量分析，表明大肠腺瘤和腺癌的腺上皮细胞以正常杯状细胞和柱状细胞的色度学特征分布为基准可划分为两大类：杯状细胞性腺上皮和柱状细胞性腺上皮。

Microscopy revealed apoptotic characteristics,including chromatin condensation and cell nucleus fragmentation, demonstratingthat ardipusilloside I induced apoptosis.

ArdipusillosideⅠ治疗后的瘤细胞在显微镜下显示出明显的凋亡特征，包括染色质浓缩边集，细胞核分裂；这表明ArdipusillosideⅠ诱导了瘤细胞凋亡。

Lesion contrast conspicuity, lesion, homogeneity, and delineation of lesion margin. Results The positive rate of microadenoma was 94% for dynamic?

临床拟诊的垂体微腺瘤50例行快速自旋回波对比剂动态增强扫描，接着行常规增强扫描，比较动态增强和常规增强两种办法对垂体微腺瘤的检出率。

Methods 50 cases of clinically suspected microadenoma were examined with dynamic enhanced mr imaging, and standard imaging with unenhanced and contrast enhanced spin echo sequences were obtained. the threesequences were evaluated retrospectively and graded for gland lesion contrast conspicuity, lesion, homogeneity, and delineation of lesion margin.

临床拟诊的垂体微腺瘤50例行快速自旋回波对比剂动态增强扫描，接着行常规增强扫描，分析比较动态增强和常规增强两种方法对垂体微腺瘤的检出率。

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。
