PartⅡDiffusion-weighted MR Imaging of breast mass and non-mass lesionPurpose:To evaluate Diffusion-weighted MR Imaging of breast mass and non-mass lesion in lesion characterization by comparing ADCs of malignanty with benignancy.

第二部分磁共振扩散加权成像在乳腺肿块性病变和非肿块性病变中应用价值的对比研究目的：对比乳腺良、恶性病变的表观弥散系数(apparent diffusioncoefficient，ADC)，探讨DWI在乳腺肿块性病变和非肿块性病变中的诊断价值。

Materials and Methods:236 pathology-confirmed breast lesions(155 malignanty,81 benignancy) and 221 disease-free contralateral breast tissues were examined using EPI-DWIb values=0,1000 s/mm~2TR/TE=8400ms/93.8ms; FOV=30×30cm;matrix=128×128;ASSET=2,slice thickness=4mm.DCE-MR imaging was also performed for accurate location of the lesion using VIBRANT sequence.The mean ADC values of malignant and benign lesions and the disease-flee contralateral breast tissues were calculated from the ADC map for each patient.One-way analysis of variance was applied to compare the mean ADCs of malignant lesions with benign lesions and disease-flee contralateral breast tissues.The threshold ADC value for malignant lesion was determined using a receiver operating characteristic(ROC curve analysis.Each lesion was classified into two major types:mass and non-mass lesion.The diagnostic performance of DWI was compared in breast mass and non-mass lesions.Results:155 malignant and 81 benign lesions were confirmed in 236 lesions.

材料与方法：搜集术前行乳腺MR检查并经穿刺或手术病理证实的236例乳腺病变，以对侧正常乳腺腺体作为正常对照，采用横轴位的平面回波-扩散加权成像序列，TR=8400ms，TE=93.8ms，层厚=4mm，激励次数=2：视野=30×30cm，矩阵=128×128，ASSET=2，b值=0和1000s/mm~2；参考动态增强图像准确定位，测量病变区和对侧正常乳腺腺体的ADC值，应用t检验比较良、恶性病变及正常腺体ADC值的差异，采用接收者工作特征曲线(receiver operating characteristic curve，ROC)确定良恶性病变的ADC界值；根据BI-RADS MRI将乳腺病变按照形态学表现分为肿块性病变和非肿块性病变两组，比较ADC值在肿块和非肿块性病变中定性诊断的效能。

Professor of Medicine Department of Peking University, Beijing Ditan Hospital director of the Center for STD and AIDS in Tsui Hark-yi "Life Times" said in an interview with reporters, said the tradition of the past, we only five kinds of STDs, including gonorrhea, syphilis, chancroid, sexually transmitted diseases of lymphatic granuloma And groin granuloma. 1975, the World Health Organization extended to the concept of sexually transmitted diseases,"sexually transmitted diseases," and now is mainly through sexual transmission of a group of infectious diseases.

北京大学医学部教授、北京地坛医院性病艾滋病中心主任徐克沂在接受《生命时报》记者采访时表示，以往我们所说的传统性病只有5种，包括淋病、梅毒、软下疳、性病性淋巴肉芽肿和腹股沟肉芽肿。1975年，世界卫生组织把性病概念扩展到"性传播疾病"上，现是指主要通过性接触传染的一组传染性疾病。

Drivers,attendants,individual operators and people who were unemployed get extramarital infection of STD easily with the low utilization rate of condoms.74.5 percent to seek medical help because of having the symptoms;Only 82.7 percent,62.2 percent,57.1 percent and 30.0 percent STD patients indicated that they would encourage their spouse,cohabitant,unlicensed prostitute and temporary sexual partners to be detected for sexually transmitted diseases.

驾驶员、服务员、个体经营者和无业人员等职业人群易从非婚性接触感染性病，且安全套使用率低。74.5％因为出现临床症状才求医；分别只有82.7％、62.2％、57.1％和30.0％性病患者表示会鼓励其配偶、同居者、暗娼和临时性伴就诊作性病检测。

"Venereal disease" has to be used, not only will those who are suffering from sexually transmitted diseases, a mental pressure, but also those who did not have the sexually transmitted from person to person,"allergy."

"性病"这个字眼，不仅会让患有性病的人感到一种精神上的压力，而且还会让那些并没得性病的人产生"过敏"。

to show basic knowledge and disservice of venereal diseases to the officers and soldiers are important.

在官兵中加强性病基本知识的宣传，强调性病的危害对部队防治性病很有必要。

The society aims to promote the interest in and a better understanding of dermatology and venereology, to provide a venue for discussion of problems related to dermatology and venereology, to improve the standard of dermatological and venereological care, and to provide a means of liaison with workers in dermatology and venereology in other parts of the world.

该学会主要目的有：提高人们对皮肤病和性病的兴趣和理解；提供一个讨论与皮肤病和性病相关话题的通道；促进皮肤病和性病治疗的水平；促进各地皮肤病和性病工作者的相互联系。

Objective To report the application of syndromic approach for STIs management in private and public clinics in three rural towns in Hainan and Guangxi provinces.

目的报告在海南省和广西壮族自治区三个农村城镇的公立和私立诊所，开展性病病征处理和性病预防培训后性病病征处理的应用情况。

objective to study the prevention and treatment of veneeal diseases in the troops.methods the officers and soldiers in four camps were investigated randomly by ten questions dlsigned for veneral diseases.results the majority of officers and soldiers have got the basic knowledge of venereal diseases,but else of them have not yet.

设计10个与性病有关的问题，对随机抽样某师4个营官兵现场无记名调查。结果有关性病的基本知识已被大部分官兵所认知，但也有一部分官兵对性病缺乏了解，甚至误解。

PART 1 EXPRESSION OF MMP/TIMP IN SKELETAL MUSCLE OF ARTERIAL OCCLUSION DISEASE MODELS OF DOG'S HIND LIMB Objective To study the distribution changes of typeⅠand typeⅢcollagen in skeletal muscle of arterial occlusion disease models of dog's hind limb and the expression of MMP-2/TIMP-2 in skeletal muscle of arterial occlusion disease models of dog's hind limb. To investigate the significances of collagen metabolism and MMPs in skeletal muscle remodeling due to ischemia.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
