简介：AbstractIntroduction:Genital herpes is one of the most common sexually transmitted infections worldwide. Most genital herpes occur on the genitalia, perineum, buttocks, upper thighs, or perianal areas. However, there were reports of rare cases of genital herpes on urethral orifice.Herein, we report a case of a patient who was diagnosed with urethral orifice genital herpes, a place likely to be ignored.Case presentation:A 53-year-old woman presented with vagina pruritus at first, with subsequent burning sensation around urethra. Mycostatin and mycospor were administered for the treatment of the pruritus. Then levofloxacin was prescribed. Finally, the patient was given treatment with acyclovir. Different from other cases, the investigation showed herpes simplex virus type 1 DNA positive and herpes simplex virus type 2 DNA negative by PCR. The patient was therefore diagnosed with genital herpes.Discussion:Most genital herpes happen on the genitalia, perineum, buttocks, upper thighs, or perianal areas. Few cases have been reported that genital herpes occurred on urethral orifice till now.Conclusion:If there is no typical symptoms that patient present with herpes simplex virus type 1 or 2 positive, urethral orifice genital herpes should be considered.

简介：摘要目的本研究从血清学及临床保护角度探讨单纯疱疹病毒1型(herpes simplex virus type 1，HSV-1)和HSV-2免疫交叉反应的特征，以期为控制及预防这两种病毒引起的疾病提供数据资料。方法HSV-1减毒株M3免疫小鼠，检测其诱导产生以中和抗体为指征的特异性免疫应答情况。免疫28 d后分别用HSV-1野毒株和HSV-2野毒株经不同途径对小鼠进行攻击感染，观察M3免疫小鼠抵御HSV-1/2病毒感染的情况。结果HSV-1减毒株M3免疫小鼠不能诱导产生特异性的抗HSV-2中和抗体，免疫28 d后接受不同途径的HSV-2攻击，病毒载量显著增加，但未出现明显的异常临床表现，同时组织病理损伤也仅表现为较轻微的炎性反应。HSV-1减毒株M3免疫小鼠能够诱导产生特异性的抗HSV-1中和抗体，并且在HSV-1野毒攻击后表现出明显的保护效果。结论HSV-1减毒株M3免疫小鼠后所诱导的免疫应答对HSV-1野毒株感染攻击表现出以中和抗体为特征的、可限制病毒在体内增殖的免疫保护作用，然而对HSV-2野毒株攻击则表现出不以抗体形式中和病毒而是以控制病毒的增长为主要模式的临床交叉免疫保护能力。

简介：单纯疱疹病毒（HSV）感染是人类一种常见病、多发病。目前主要的治疗方法为全身及局部抗病毒治疗,能使病情得到不同程度的控制,但远没有达到根治及控制传播的目的,因此通过抗HSV疫苗的接种,诱导针对病毒的特异性自动免疫是最有效途径,尤其是DNA疫苗,更是今后重要的研究方向。

简介：摘要目的比较单纯性疱疹病毒(HSV)抗原和HSV-2型IgM抗体检测法诊断生殖性疱疹感染的临床效果。方法回顾性分析我站收治的188例生殖性疱疹疑似病例经直接免疫荧光法(DFA)检测疱液样本中的HSV抗原和ELISA法检测血清中的HSV-2IgM的检测结果，以免疫印迹法(WB)为标准，比较HSV-2IgM抗体检测法和DFA敏感度及特异性。结果188例患者确诊106例为阳性，其中原发感染30例，复发感染76例；在原发感染诊断中HSV-2IgM抗体检测法与DFA敏感度和特异性比较，差异无统计学意义(P＞0.05)；在复发感染诊断中HSV-2IgM抗体检测法与DFA敏感度比较，差异具有统计学意义(P＜0.01)；HSV-2IgM抗体检测法与DFA总敏感度比较，差异具有统计学意义(P＜0.01)。结论DFA反应迅速、操作简单，在生殖性疱疹感染诊断中敏感度和特异性均较高；HSV-2IgM抗体检测法对于原发感染诊断敏感度和特异性较高，可将两种方法结合诊断效果更佳。

简介：在HSV颜色空间的人的皮肤的特征广泛地基于内容在图象检索的区域被使用。因为它的价值为肤色有一个狭窄的范围，H作为基本识别参数被选择并且当照明紧张或皮肤表面的弯曲正在变化时，能保持稳定。有在HSV颜色空格的照明的变化的参数的规则被学习。当照明紧张被改变时，/2能使稳定的浸透和价值或皮肤表面(S+V)的平均数被变化，这第一被发现，并且(S+V)/2随着肤色变化，但是变化的趋势与H的相反。因此，(S+V)/H能被用作能提高HSV能力认出人的皮肤的一个新识别参数。CLC数字TN911.73

简介：每一种人种皮肤彩色分布在一个较窄的频带上。一般所用的RGB彩色模型对光线的亮暗程度比较敏感,而在HSV彩色模型中,色相H分量表示了图像的彩色信息,受到光线变化的影响缓慢。鉴于此,采用在HSV彩色模型下建立肤色模型,并对其进行训练,从而用训练后的模型对图像进行人脸检测。实验结果表明,提出的方法是有效而快速的。
