objective:to explore the clinical value of digital mammography on diagnosis of small breast cancer.methods:we retrospectively analyzed the representation of molybdenum target x-ray in 40 patients with small breast cancer diagnosed by biopsy.result:the molybdenum target x-ray showed nodosity tumor in 17 cases,calcification in 13 cases,density in 8 cases,focal grand architectural distortion in 6 case,single dilated in 3 cases and blood vessel line thickening in 6 case.conclusions:digital mammography is the most important means in the diagnosis of small breast cancer,which can distinguish between different kinds of breast density of different tissues and find small breast lump.the mammography has a high sensitivity in the diagnosis of small breast cancer.

目的：提高对小乳癌影像学的认识。方法：回顾性分析40例经病理证实的小乳癌患者的x线片。结果：x线表现为肿块17例，钙化13例，致密影8例，局部结构紊乱6例，单支导管扩张3例，血管影增多、增粗6例。结论：影像学是小乳癌诊断的最主要手段，能区别乳房各种不同组织的不同密度，能发现较小的乳腺肿块，对于乳腺癌的诊断，乳腺x线钼靶摄片具有较高的灵敏度。

CT findings of active tuberculosis appears as consolidation (17.4%),single cavity and small mutible cavities (13.1%),ground-glass opacity(10.9%),tree-in-bud sign(17.4%) in this study,but nodosity and mass (30.4%) were not rare,7 cases of which as border enhancement.23(82.1%) patients were diagnosed correctly and other 5 (17.9%) patients were misdiagnosed.

CT征象多表现为活动性病变，其中大片状实变影(17.4%)、空洞影包括1例多发小空洞(13.1%)、磨玻璃征(10.9%)和树芽状支气管播散病灶(17.4%)，但结节和肿块影(30.4%)也不少见，并且其中7例病灶呈边缘强化。本组CT正确诊断23例(82.1%)，误诊5例(17.9%)。

目的 探讨脑内动静脉畸形CT、MRI、CTA、MRA、DSA等影像学诊断及其与病理学表现的相关性方法本文收集颅内动静脉畸形54例，其中脑动静脉畸形45例，脑膜动静脉畸形1例，硬脑膜动静脉畸形1例，硬脑膜动静脉瘘7例，并经过CT、MRI、CTA、MRA、DSA及手术明确诊断。

Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

本研究观察了从鸡胚到出壳后的不同生长发育阶段法氏囊的组织结构，结果表明：胚胎13日龄时，法氏囊开始发育，粘膜上皮下形成结节状细胞集团；胚胎15日龄，聚集的细胞集团形成初始的淋巴滤泡；胚胎18日龄到出壳后1日龄，滤泡内淋巴细胞数量增多，多数滤泡髓质和皮质界限仍不明显；7日龄雏鸡法氏囊髓质皮质分界清晰，滤泡数量显著增多；21日龄到35日龄，滤泡由多边形逐渐转变成长方形；在35日龄时，粘膜上皮细胞逐渐增多，排列紧密，细胞核紧密排列成直线位于基底部。
