Materials Methods: Beast ultrasound was performedduring luteal phase and late follicular phase in 50 women, aged 25～45, with normalmenstrual cycle and no distinct breast disease; Serum estradiol and progesteronelevel were measured by enzyme immunoassay on the day of ultrasound performed. Onehundred of twenty nine menopause transition women and 318 menopause women wereselected. All of them had ultrasound of breast and serum estradiol report. Breast pain wererecorded. Sixty menopausal women aged 56.8 yr. and menopausal aged 8.2 yr. participated1-year double-blind, randomized, placebo-controlled and 2mg 17β-estradiol continuouscombined with 1mg norethindrone acetate clinical study. Mastalgia was diaried. Breaststructure changes tested by high-resolution ultrasound at the 0 and 12 M.

资料和方法：征集身体健康，没有明显乳腺疾病的正常月经妇女53名，分别在月经的晚卵泡期和黄体期进行超声检查和测血清雌二醇和孕酮水平；收集有HRT前乳腺超声检查和血清雌二醇水平结果的绝经过渡期妇女129名和绝经后妇女318名，记录既往乳腺胀疼、过渡期乳腺胀疼、绝经后乳腺胀疼和既往乳腺病史。17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗和安慰剂随机双盲平行对照临床研究1年的60名参加者，分别在用药前后各进行一次乳腺超声检查，乳腺症状按同一表格由病人日记及经培训的一名医生定期随诊记录乳腺胀疼出现、消失的日期及持续的天数；超声检查用同一方法测量乳腺腺体层厚度、导管宽度、乳腺腺体结构及血流。

Objective To analyse the correlation between changes of liver hemodynamies and liver fibrosis markers in patients with trichloroethylene medicamentous dermatitis and furthermore study the prognosis of these patients with liver disfunction.

目的 探讨三氯乙烯药疹样皮炎患者肝脏血流动力学参数改变与肝纤维化指标的关系，为判断三氯乙烯药疹样皮炎肝损害的程度知预后提供依据。

Methods 30 patients with trichloroethylene medicamentous dermatitis and 30 normal persons were selected as the observation group and the control group respectively; color Doppler was used to detect the spleen thickness and longitudinal length, spleen vein and artery diameters, the maximum blood velocity and blood flow of spleen vein and artery; RIA was applied to determine the serum levels of HA, LN, PCⅢ, CⅣ and CG; relevant analysis was made on the linear relationship between serum indices of hepatic fibrosis and spleen hemodynamics of the two groups.

选择30例三氯乙烯药疹样皮炎患者作为观察组，30例同时期健康体检者作为对照组，用彩色多普勒超声仪，检测脾脏厚度及长径、脾动静脉直径、脾动静脉血流量和脾静脉最大流速SPV(下标 x。用放射免疫法检测肝纤维化指标透明质酸、层粘连蛋白、Ⅲ型前胶原、Ⅳ型胶原和甘胆酸的水平，并对观察组与对照组的脾血流动力学参数与肝纤维化指标进行相关分析。

The CBF of both Megachiropteran and Microchiropteran decreased with the depression of Tb.

大小蝙蝠的脑血流都随体温的降低也有所降低。

Abstract］ Objective To explore the ultrasonic feature of Color Doppler flow imaging in the diagnosis of vitreous membranaceous pathological changes.

目的 探讨彩色多普勒血流成像技术对玻璃体内膜样病变的超声诊断特征。

Methods With CDFI 42 cases (47 eyes included) of vitreous membranaceous pathological changes were analyzed,and compared with the results after operations,combining with the image features of 2-D ultrasonography and the blood flow distributing of color Doppler flow imaging.

应用CDFI对42例(47只眼)玻璃体内膜样病变进行探查，结合二维（2D）形态特征和CDFI血流分布特点，与手术结果进行对比分析。
