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。

Polymarase Chain Reaction may be the better method of detecting M.tuberculosis than other methods and lead us to carry out a series of research on this problem. This thesis is composed of five parts:(1)systematic evaluation for the first time of the ability of five defferent PCR methods to detect M. tuberculosis;(2) using the endonuclease and southern blot by a radioactive and a nonradioactive labeled probe, to confirm the specificity of the PCR products and to analyse the sensitivity of detection by southern blot method using digoxigenin-labeled probe;(3) evaluation of acid-fast staining, bacterial culture and PCR for the detection of M. tuberculosis in sputum, pleural and peritoneal effusion samples;(4) The feasibility of PCR for detection of M tuberculosis on formalin-fixed paraffin embedded tissues;(5) 26 cases of sarcoidosis were retrospectively studiedwith PCR for M. tuberculosis and nontuberculosis Mycobacterium and the problems on histopatholoical diagnosis of sarcoidosis are discussed.
