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。

The ELISA titre was 1:2000.By cell fusion, 46 hybridoma cell lines were screened,and 10 lines were cloned with limited dilution method.16 lines secreting anti-bFGF monoclonal antibody were been developed, and 2 lines targeted fusion protein. Sensitive ELISA and dot-ELISA for bFGF was developed with this mAb. The detection limit of them were 0.1 ng/well and 0.5 ng/well. The expression level of anti-bFGF mAb by different rebuilt engineering cells were identified by western blot and to direct rebuild recombiment engineering cell. The dose and character of anti-bFGF mAb inhibiting bFGF biology activity were searched by 3T3 cell line. Searching 20 tissue of liver cancer, liver cancer cell lines and general tissue of liver, finding bFGF were highly expressed in tissues of liver cancer and liver cancer cell lines. Affinity chromatography purifying bFGF was set up by mAb binging CNBr-pepharose 4B, and the purification was 95%. We found that the titer of anti-bFGF antibody was very high in serum of neuropathic amyotrophia.
