简介：近年来,性病已成为发病率较高的传染病,已引起社会各界的普遍关注。随之而来的一些不法游医、个体开业医和一些未经批准诊治皮肤性病的医疗机构一哄而起,到处开设皮肤性病专科门诊。不论城市的大街小巷和农村集市随处可见“皮肤性病专科”、“祖传秘方治性病”、“精治、包治各种皮肤病”的广告招牌,电视、报刊刊播的医疗广告也多为皮肤性病广告。部分地区还

简介：乳房外Paget病（EMPD）是一种罕见的，发生于乳房外的一种表皮内存在Paget细胞的湿疹样癌。可发生于外阴、阴囊、腹股沟、阴茎、肛周等大汗腺丰富的部位，常常与表皮内肿瘤和内脏肿瘤有关，由于表现多种多样易出现误诊。在病理上应与Bowen病，浅表型恶性黑色素瘤区别，发生于外阴的乳房外Paget病在临床上更易误诊为湿疹，脂溢性皮炎。本文介绍了2例被误诊的Paget病，同时复习了国内外有关本病的一些诊断和治疗方面的进展。

简介：性对于人类本来是普遍的问题,早在先秦时代就有学者把性解释为“饮食男女”等。提出这种观点者首先是孔门儒学传人,由此可以认为,在中国把性当作“科学”来研究,并努力阐发有关的性教育观念,当属先秦儒家代表人物的有益作为。回瞻今世,在我们生活的星球上有不少成年男性和女性,(他们不分国别、地区),总在贪婪地寻求着性的系列“服务或刺激”(指卖淫、嫖娼……),由此导致世界上性病不断泛滥,人与人之间的道德伦理日益沦丧。正由于这些存在于人类间的丑恶现象,才使世间

简介：英语"青春期"(puberty)一词来自拉丁语"pubeffas",其含义是"具有生殖能力",是指儿童逐渐长大为成年人的一个过渡期,是根据第二性征的出现和生殖器官功能逐渐发育成熟而指称的一个特定阶段.世界卫生组织(WHO)将青春期的年龄范围定为10岁～20岁,是少男少女从小学生到中学生的成长期.伴随身体迅速发展的是心理急剧变化.

简介：目的研究单纯疱疹病毒2型(HSV-2)对人单核细胞表达HLA-Ⅱ类抗原(HLA—DR、HLA-DQ)的影响，探讨单核细胞及HLA-Ⅱ类抗原在单纯疱疹病毒2型感染中的作用。方法用单纯疱疹病毒2型(333株)感染人单核细胞，于感染后1、3、5、7天分别收集细胞，用APAAP法检洲单核细胞HLA—DR、HLA-DQ表达水平。结果单纯疱疹病毒2型感染后1天，单核细胞表达HLA-KR、HLA—DQ抗原水平明显降低，以后逐渐升高，至7天达到对照组水平。结论单纯疱疹病毒2型感染早期能抑制单核细胞表达HLA—Ⅱ类抗原，HSV-2抑制单核细胞表达HLA-Ⅱ类抗原可能是HSV-2入侵机体的手段之。HLA-Ⅱ类抗原在单纯疱疹病毒2型致病及免疫过程中可能起重要作用。
