血汗症是指在无破损的皮肤黏膜表面有发作性溢血现象,中医又称"肌衄"、"血剑"、"汗血"等;西方宗教称之为"圣痕".该病极为罕见,迄今文献中仅有80例报道[1],且多为19世纪前病例,其可靠性较低,因本病需排除自残、毛细血管扩张或色汗症的可能性[2,3].21世纪以来,国内外报道了6例[4~9].血汗症的病因不清,Holoubek等[1]按病因分为:(1)伴发系统性疾病;(2)替代月经;(3)过度劳累;(4)心理因素;(5)特发性. 相似文献

INTRODUCTIONAngiogenesis is the process of new blood vesselformation from existing blood vessels and a natural re-sponse of tissues to ischemia[1]. The steps of angio-genesis involve proteolytic degradation of extracelluarmatrix, endothelial cell-matrix adhesion, migration,proliferation, and differentiation[2]. This biological re-action is often associated with some diseases, such assolid tumor[3], diabetic retinopathy[4], and rheumatoidarthritis[5].Tumor formation requires the developm… 相似文献

新冠肺炎是由新型冠状病毒感染引起的一种急性呼吸道传染病[1].患者从疑似、隔离到确诊,不仅要承受身体痛苦,还承受着巨大的精神痛苦,从而加大了治疗难度[2-3].为保证患者积极配合新冠肺炎的治疗,早日康复,需要同时关注其心理感受,必要时联合精神药物以有效控制患者的精神症状[4].四川大学华西医院"阳光医院"项目始创于2012年,目标是在综合医院中调整原有的服务理念、模式和流程,整合心理服务的内容,增强临床护理人员的心理社会性关怀能力,真正体现生物-心理-社会的医学模式[5].在该项目的具体实施中,一方面护理人员需要接受系统的心理知识培训,并掌握华西医院自主研发的"华西心晴指数问卷"等快速评估工具;另一方面医院也建立并逐步推广综合医院非精神科患者心理问题的分级处理流程.此次我们将这一模式运用到抗疫一线,以帮助重症新冠肺炎患者重建健康心理,获得了良好效果,现报道如下. 相似文献

Phytoestrogen genistein decreases contractile response of aortic artery in vitro and arterial blood pressure in vivo 总被引:12,自引:2,他引:10
INTRODUCTION Phytoestrogens are naturally found in many plants,particularly soy beans, and they are defined as plantsubstances that are structurally or functionally similarto estradiol[1,2]. Genistein, a phytoestrogen, may haveestrogenic cardioprotective actions[3]. Epidemiologicaldata suggest a reduction in the incidence of coronaryheart disease in humans who have a high intake ofphytoestrogens[4]. Increased plasma levels of thephytoestrogen genistein are suggested as an explana-tion for… 相似文献
