In our study, we found menadione has anticancer potential on human breast adenocarcinoma MDA MB 231 by weather cell cycle arrest, anti proliferation, or apoptosis. Low concentration of menadione (5.8μM) significant inhibited growth curve on breast cancer cells (MDA MB 231) but not breast cells (MCF 10A) by performing MTT and trypan blue cell counting. RT-PCR and western blotting showed menadione increase p21 gene and protein expressions but decrease cyclin E and CDK2 protein expression resulting in cell cycle G0/G1 arrest by flow cytometry.

MTT及生长曲线的实验，发现menadione在低浓度且长时间作用情况下，对在於人类乳腺上皮细胞癌(MDA-MB 231)是有明显的抑制作用，而在正常乳腺细胞(MCF-10A)则没有影响，在分子转录上及蛋白质表现方面也发现低浓度menadione处理24时能使MDA-MB 231诱发p21基因及蛋白表现量增加及cyclin E、CDK2抑制，再经由流式细胞仪分析也发现低浓度 menadione 处理24小时能使MDA-MB 231细胞周期GO/G1比例上升，造成细胞周期停滞，进而抑制细胞生长。

Methods 56cases were choosed,which were female patient,and were diagnosed as parenchymatous tumor by ultrasound,were punctured guided by high frequency with au-tomatic biopsy gun and18G puncture needle made in Japan.2pieces sampled and tested for pathology.

Results 3 cases were systic masses under nipple tie 4cases were small multi systic masses in the breast gland 7 cases were mixed echoic masses; 5cases were hypo-echoic masses which maintained breast gland structure and 2 cases were hypoechoic masses.

结果 21例可消退性乳腺肿块，表现为乳头下囊性肿块3例，乳腺内多发性小囊肿4例，乳腺内混合性肿块7例，保持腺体结构的回声减低肿块5例，低回声肿块2例。

In this paper, we define quadratic spline as wavelet, do the two dimentional dyadic wavelet transform on near-infrared galactophore image, and get local modulus maxima from wavelet transforms results----rnodulus and angles, so we can find the blood vessel edge image in each scales, at last, we compute a good edge image which synthesize the characters in each scale.

本文中用二次样条小波作为小波基函数，对乳腺近红外图像进行二维二进小波变换，计算小波变换结果的局部模极大值点，得到各个尺度下的乳腺近红外图像血管的边缘，最后得到综合了各个尺度特征的较好的血管图像的边缘。

A small benign intraductal papilloma appears here in a breast duct, typically in one of the main lactiferous ducts beneath the areola.

Thirty two point six percent (42/129) of menopausetransition women and 18.9％(60/318) of menopause women had breast structure changes,〓=9.26, P＜0.01. The frequency of breast structure changes decreased with decreasing ofserum of 〓 level and increasing of age. Four (4/29, 13.8％) in HRT group had breaststructure changes, which disappeared after discontinuing HRT or reducing the dose of HRTin 3 subjects. Conclusions: Most of normal menstrual women and menopause transitionwomen experienced Mastalgia; Mastalgia occurred in 89.7％ of subjects and lasted forabout 2 M. in the 1-year ccHRT; Image of breast ultrasound changed following menstrualcycle in normal menstrual women; Breast pain and breast structure change may be causedby higher 〓 and P level in luteal phase; The breast structure changes of HRT user weresimilar to that in normal women and were reversible.

大部分正常月经妇女和绝经过渡期妇女有周期性乳房胀疼，绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年中大部分使用者有持续约两个月的乳房胀疼；乳腺体层厚度随体内雌孕激素水平的下降和年龄的增加而逐渐萎缩，绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年后，对乳腺体层的厚度没有明显的影响；超声下乳腺结构改变主要受体内雌孕激素水平的影响，正常月经妇女中1／3的乳腺结构改变具有可逆性，绝经过渡期和绝经后妇女中有一半的乳腺结构改变的特征类似正常月经妇女具有可逆性的乳腺结构改变；绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年后，少数使用者出现的乳腺结构改变可随药物剂量的调整或停药而恢复；对长期HRT使用者仍需加强乳腺的监测，长期HRT对乳腺的影响值得进一步研究。
