目的评价支架裂隙对支架植入病人远期发生支架内冠状动脉再狭窄的影响。方法对进行多层螺旋CT检查的347例病人进行随访,共植入781个支架,进行支架裂隙和支架内再狭窄的评价。根据临床及支架特征,病人被分为有支架裂隙和没有支架裂隙两组。在后续研究中,对82例病人共175个支架进行评价(26例评估通过常规冠状动脉造影,其中6例通过电话调查,46例通过CT血管成像检查,10例进行了常规冠状动脉造影及CT血管成像两项检查),在有支架裂隙和没有支架裂隙两组间进行支架内再狭窄发生率比较。结果 3例病人和13个支架被排除在外,12.5%的病人和8.6%的支架被发现有支架裂隙。CTA检查发现,21.2%的有支架裂隙的病人发生支架内再狭窄,占发生支架内再狭窄的23.7%,支架数目、长度、位置、重叠方式及支架弯曲角度为支架裂隙的影响因素。有支架裂隙病人在接下来的15个月中,支架内再狭窄的发生率明显高于没有支架裂隙组(43.8%/14.9%由CCA进行评价,33.3%/10.1%由CTA及CCA进行评价)。结论 CTA发现有支架裂隙的支架植入病人支架内再狭窄的发生率较高,说明长期或进一步的干预是必要的。的翻译是:

硫化氢(hydrogen sulfide,H2S)作为新的气体信号分子参与多系统生理及病理生理功能的调节,并受到学术界广泛关注。但迄今为止,血液中H2S浓度的检测依旧是本领域的一大难题。本文旨在建立一种简易的改良亚甲基蓝分光光度计法,提高亚甲基蓝法检测H2S浓度的敏感性。亚甲基蓝法测定血浆H2S时,大量血浆蛋白会影响测定结果。本方法先加入过量醋酸锌溶液使血浆中游离H2S、HS、S2形成ZnS沉淀,并使血浆蛋白变性析出;加入5mol/L NaOH强碱溶解变性的蛋白,而ZnS沉淀不溶于强碱;离心去除大量蛋白质;再加入0.2%N,N-二甲基对苯二胺盐酸盐溶液使ZnS完全溶解,用三氯乙酸沉淀剩余蛋白质,最后用分光光度计法测定H2S浓度。结果显示,各种离子甚至硫酸根离子以及硫代硫酸根离子不影响该方法检测的特异性。而向样本中添加4.5%白蛋白可降低检测数值,表明H2S与蛋白质结合影响本方法的检测,而且该方法不能检测全部与蛋白结合的H2S。该方法回收率为81.9%,表明该方法的精确度基本达到要求。利用该方法检测到65名健康志愿者的冻存血浆样本H2S浓度为(13.93±4.98)μmol/L,且SD大鼠新鲜和冻存后血浆H2S...的翻译是:

验证码输入错误,请重新输入血痰中的艾滋病毒会引起感染吗
一次吃快餐的时候,在菜里面吃到了类似血痰的东西,当时因为前天吃面烫伤了上颚,都蜕皮了,很疼的,当时没敢吐出来,直接吃了进去,我对面坐着一位男士,请问如果那痰里面有血,血里面又有艾滋病毒,我会感染吗?

我也有相同经历&&到底会不会被感染啊&急死人了!
请登录后再发表评论!艾滋病病毒感染者虽然外表和正常人一样,但他们的血液、精液、阴道分泌物、皮肤粘膜破损或炎症溃疡的渗出液里都含有大量艾滋病病毒,具有很强的传染性;乳汁也含病毒,有传染性。唾液、泪水、汗液和尿液中也能发现病毒,但含病毒很少,传染性不大。脑脊液、骨髓、中枢神经系统和皮肤均可分离到病毒。
  已经证实的艾滋病传染途径主要有三条,其核心是通过性传播和血传播,一般的接触并不能传染艾滋病,所以艾滋病患者在生活当中不应受到歧视,如空气、食物食具、共同进餐、饮水、握手、日常用具等都不会传染艾滋病。
  (1)性接触传播 包括同性及异性之间的性接触。肛交、口交有着更大的传染危险。与HIV性传播有关的高危人群为:男性同性恋者、妓女、嫖娼者、多个性伙伴者、性乱者。美国调查发现,同性恋者的HIV感染率高达20-30%。西方国家70%的HIV感染者为男性同性恋者。在非洲、东南亚一些国家,80%以上HIV感染者因异性性接触所致,女患者中81%为妓女。在经济条件差的妓女中,HIV抗体阳性率高达66%。在这些国家中,异性性活动是HIV的主要传播方式。
  (2)血液传播 包括:①输入污染了HIV的血液或血液制品;在未对献血者进行HIV抗体检测之前,输血及血制品具有感染HIV的极大危险性。在非洲30%的HIV感染儿童是输血所致。使用从大量献血者血浆中提取VIII凝血因子治疗血友病患者发生感染的危险性最大。②静脉药瘾者共用受HIV污染的、未消毒的针头及注射器;1986年美国调查发现,AIDS患者中25%有静脉注射毒品吏。在西方国家注射毒品是感染HIV的第二大因素。③共用其他医疗器械或生活用具(如与感染者共用牙刷、剃刀)也可能经破损处传染,但罕见。④注射器和针头消毒不彻底或不消毒,特别是儿童预防注射未做到一人一针一管危险更大;口腔科器械、接生器械、外科手术器械、针刺治疗用针消毒不严密或不消毒;理发、美容(如纹眉、穿耳)、纹身等的刀具、针具、浴室的修脚刀不消毒;和他人共用刮脸刀、剃须刀、或共用牙刷;输用未经艾滋病病毒抗体检查的供血者的血或血液制品,以及类似情况下的输骨髓和器官移值;救护流血的伤员时,救护者本身破损的皮肤接触伤员的血液。
  (3)母婴传播 也称围产期传播,即感染了HIV的母亲在产前、分娩过程中及产后不久将HIV传染给了胎儿或婴儿。可通过胎盘,或分娩时通过产道,也可通过哺乳传染。在非洲有2-15%的AIDS病例由母婴传播。HIV感染的孕妇所生婴儿有30-70%在围产期被HIV感染。一般认为,婴儿在产道感染HIV的机会在于经胎盘感染。
  最近认为性病患者,特别是有生殖器溃疡者(如梅毒、软下疳、生殖器疱疹)也应列为艾滋病的高危人群。
