我妈妈因为左边乳房不舒服，上周3月12日去做了Mammogram和ultrasound,结果出来了
，很不好，现在把结果贴出来，请各位XDJM帮忙看看：
“Color flow and real-time ultrasound were performed on the left breast.
Same day ultrasound perform for evalution of mammographic abnormality
demonstrades a 4.5x 2.4x4.2 cm lobulated solid mss with internal flow within
the left breast 2-3 o'clock.
Conclusion: ACR BI-RADS CATEGORY 4C: MODERATE SUSPICION FOR MALIGNANCY
The lobulated mass with flow in the left breast seen on mammogram and
ultrasound is at a moderated ... 阅读全帖 |

那个兄弟姐妹帮我看看下面说的是什么。名词太多，看不懂。
谢谢。

FINDINGS:
Limited images of the lower brain demonstrate no gross abnormality. In the
axial plane, there is an apparent ring enhancing 7 mm lesion in the left
cerebellum, but sagittal images suggest that this appearance is created by a
looping tortuous vessel rather than a true focal lesion.
Rounded soft tissue densities in the left maxillary sinus and left nasal

严重一些，不知哪位能帮忙解读一下。万分感谢
Findings: There is significant thrombus within the right lower lobe
pulmonary artery, which distends the artery somewhat and is nearly occlusive
. There are several vessels distal to this, which also appear to contain
thrombus. Contrast does, however, pass beyond this into the more distal
branches. There is what appears to be peripheral consolidation, which has a
lobulated,slightly ill-defined contour, which could represent focal
infa... 阅读全帖 |

Tubular adenoma: most common polyp, the head of the stalked polyp has a
lobulated, mushroom-like appearance.
This is consitent with the figure presented in the question. The stalk of
the polyp is just under the mushroom-like head.
The adenoma has a great chance to develop into maglinant carcinoma since the
adenoma >2cm. |

2. don't know. Sorry.
Megaloblastic anemia=multi-lobulated neutrophil+macrocytic anemia
Alcohol inhibit folate acid absorption, also interfere with Heme synthesis.

I could be wrong on both. Welcome other experts! |

发帖数: 106 | 11 多谢君荷，我对关于magloblastic and macrocytic一直都没搞清楚过，再请教一下，
看我理解是否正确：1，magloblastic是专对于有骨髓抑制而言的，正因为骨髓抑制，
才会出现multi-lobulated neutrophil（发育不全？）。5FU若也引起骨髓抑制，那也
会引起magloblastic，所以这不是绝对的，当然真实情况可能发生几率较小。2，相对
于骨髓抑制，红细胞对DNA损伤比较敏感(可能是新成代谢比别的血细胞快？），所以有
些药物可引起macrocytic, 却还
没到magloblastic的程度。 |

发帖数: 530 | 13 美国塔夫茨大学医学院的研究人员通过对老鼠研究发现两种与乳腺细胞分化有关的前体
细胞中，其中一种或许是导致管腔
型的乳腺癌的前体细胞。这项研究发表在1月19日的《Cancer Cell》杂志上，或将对治
疗乳腺癌提供一种新的治疗靶标。
乳腺癌一般分为两类：一类是管腔型(Luminal-like)乳腺癌，这种乳腺癌对激素十分敏
感，生长缓慢，是乳腺癌中最常见的
一种；另一种是具有侵润性的基底细胞样型(Basal-like)乳腺癌,这种乳腺癌对激素不
敏感，一般预后较差。之前有研究人员
认为这两种癌症可能是由不同的前提细胞分化而来。
最近，塔夫茨大学Charlotte Kuperwasser主持的课题组对老鼠研究，发现了不同类型
的乳腺前体细胞，而管腔型乳腺癌
细胞来自于小叶前体细胞(lobule progenitors)的分化。研究人员还发现，这类前体细
胞与一种参与细胞自我更新和分化的
蛋白质cyclin D1的活性有关。研究人员使模式老鼠中cyclin D1蛋白失活，与对照组小
鼠相比，cyclin D1蛋白失活组老鼠
小叶祖细胞的数量很少，且不出现管腔型乳腺肿瘤。
