简介:目的:调查了解当前90后护理专业女大学生的择偶观现状,以便发现不良问题,及时进行教育引导。方法:围绕择偶时对方的相貌、身体、贞洁、年龄、经济、社会地位、肤色、性格等在大一到大三的女护生中开展调查,全部问卷按照年级进行分组,采用多组卡方检验。结果P〈0.05为有统计学意义。结果:3组女护生在“贞洁”(x2=24.91,P=0.000〈0.01)、“年龄”(x2=16.45,P=0.012〈0.05)、“经济”(x2=42.17,P=0.000〈0.001)3个方面存在显著差异。而其他方面无显著性差异,P〉0.05。结论:90后女大学生择偶观随个人喜好而定,但随着年龄的增长她们的择偶观有所变化,开始考虑现实问题,走向成熟与理智。
简介:目的检测活化型表皮生长因子受体(EGFR)和转录调节因子E2F在尖锐湿疣中的表达。方法采用免疫荧光方法观察活化型EGFR和E2F在尖锐湿疣(CA)皮损中的表达情况。结果活化型EGFR在CA皮损角质形成细胞膜上的表达较正常对照组显著增强(P<0.01)。而且,活化型EGFR和E2F在CA皮损中的双重阳性表达较正常对照组显著增强(P<0.01)。结论活化型EGFR表达的增强导致核内转录因子的激活而参与CA的增殖病变。
简介:报告2例上皮样血管瘤,分别为18岁女性和10岁男性患者,临床表现均为皮肤出现丘疹、结节、质硬肿物。病理表现均为真皮浅层血管增生、扩张,血管内皮细胞肿胀,凸出管腔,形成墓碑状,真皮下层血管增生,管周不等量淋巴组织细胞、嗜酸性粒细胞浸润,并可见淋巴滤泡形成。诊断符合上皮样血管瘤。并对其病因、临床特征、诊断和治疗进行综述。
