简介:获得性反应性穿通性胶原病属于穿通性疾病中的穿通性胶原病,其临床表现为中心出现脐凹的丘疹,覆以不易剥脱的痂皮,组织病理学可见表皮局部缺损,痂皮内可见变性的胶原纤维,真皮乳头可见胶原束穿出。本文报道3例获得性反应性穿通性胶原病并对其临床诊断、病理学改变及鉴别诊断进行归纳。
简介:Objective:AllelicpolymorphismsofCCR5△32、CCR2b-64I,CX3CR1-249I280MandSDF1-3’AassociatedwithHIV-1infectionanddiseaseprogressionwereinvestigatedinindigenousUygurpopulationsfromtheXinjiangUygurAutonomousRegionofChina.Mithods:Thestudypopulationcomprised316healthyUygursubjectswithanagerangeof1-80yearsold,fromwhomwholeperipheralbloodsampleswerecollectedandnonewereHIV-1seropositive.GenomicDNAsampleswerepurifiedusingaQiagenBloodKit.GenotypingoftheaforementionedfouralleleswasperformedusingPCRorPCR/RFLPassay,andfurtherconfirmedbydirectDNAsequencing.Results:TheallelicfrequenciesinChineseUygurpopulationwereasfollows:3.48%forCCR5△32;19.45%forCCR2b-64I;13.8%forCX3CRI-249I280Mhaplotype,and20.41%forSDFI-3’A.MutantalleledistributionsamongUygurpopulationswereinaccordancewiththeHardy-Weinbergequilibrium.NostatisticaldifferencewasfoundbetweenthefrequencyofthethreeHIVcoreceptorsandtheirrespectiveligandgenes.Conclusion:ThefrequencyofSDF1-3’AandCX3CR1-249I280MhaplotypemorecloselymatchedthehanChinese.ThefequencyofCCR5△32inUygurpopulationswasbetweenCaucasianandHanfrequencies,themorecloselymatchingthefrequencyinMedi-Asiapeople.NogeneticlinkagebetweenanytwoofthethreeHIVcoreceptorgeneswasfound,butobviousgeneticlinkagesexistedbetweenCX3CR1-249IandCX3CR1-280M,withevenhigherlinkagedegreesthanCaucasianpeople.
简介:目的观察比较液氮冷冻、电灼和Nd:YAG激光3种治疗方法对化脓性肉芽肿的治疗效果及术后瘢痕情况。方法2001年以来门诊收治的186例化脓性肉芽肿惠儿,分别采用液氮冷冻、电灼和Nd:YAG激光3种方法进行治疗,观察分析其疗效。结果3种方法治疗有效率比较差异无统计学意义(P〉0.05),液氮冷冻组与电灼组、激光组在一次性治愈率方面比较差异有统计学意义(P〈0.01)。液氮冷冻组术后瘢痕形成最轻,电灼组最重。结论3种治疗方法对化脓性肉芽肿均有良好疗效,一次性治愈率电灼组和激光组优于液氮冷冻;液氮冷冻组对组织损伤较小,瘢痕形成较轻,激光组次之。
简介:水通道蛋白(AQP)是一类能快速转运水的膜整合蛋白,目前发现其在哺乳动物中有13个亚型,不同AQP亚型的分布具有组织、细胞、亚细胞特异性。皮肤上分布的水通道蛋白主要是AQP3。AQP3介导的水、甘油运输对于皮肤功能具有十分重要的意义。它的功能缺陷可导致皮肤干燥、弹性下降和屏障作用减弱等皮肤损伤。
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:报告3例以生殖器疱疹为首症的艾滋病。例1,女,35岁,外阴溃疡伴疼痛2月余;例2,女,27岁,外阴肛周溃疡反复4月,伴发热咳嗽气促、体重下降;例3,男,37岁,尿道口反复糜烂1年,龟头包皮阴茎多处糜烂4天。3例患者均表现为多发严重难以愈合的糜烂溃疡,经免疫印迹法确诊HIV-1抗体阳性,CD4^+T细胞、CD4^+/CD8^+比值明显下降,HSV-Ⅱ-DNA定量检测阳性。提示对以多发难以愈合的溃疡为表现的生殖器疱疹患者,应仔细询问病史并进行必要的检查以排除艾滋病。
