病情描述:请问面部3度烧伤多久会痊愈。痊愈之后会不会留疤痕。
医生建议:你好.建议可以用碘伏局部清洁消毒.用无菌针管穿刺肿泡抽出泡里面的液体就可以了.适当可以服用一些抗生素如过是成年人可以用氧氟沙星胶囊等.

病情描述:现在我有一个朋友,不知道怎么回事,出了意外,出现了这种烧伤,而且是大面积烧伤,如何护理才好?
医生建议:如果烧伤病人特别严重的话,那么在护理的时候一定要注意,这个时候是绝对要预防细菌的,如果稍微有一点细菌感染,那么就有可能会导致伤口发炎,甚至还有可能会发生溃烂,而且当受伤之后做一些护理,一定要经常换洗衣服,还要经常换纱布,要经常给皮肤消毒。

病情描述:我已经烧伤2年多到哪里整形好呢
医生建议:很多整形手术不可能一次做完,一次做一部分,要知道手术也有创伤,费用不同级别医院不同地区也不同,不好说。埋置扩张器就是埋置水囊,定期打水,扩张疤痕周围皮肤,40多天后取出,切除疤痕,正常临近皮肤覆盖,建议当地烧伤整形医院就诊,好有个确切答复。

All chemical eye burns in alkali burn injury is the most serious. A large amount of research to discover, matrix metal albumen enzyme (MMP) after alkali burn cornea ulcer produce process of growth can have an important role. Since always, people are trying to find the illusion of external and internal matrix metal albumen is enzymatic restrain agent (TIMP) to prevent alkali burn after the adverse effect, now have access to the more of the eve of the pause, but the excretion of alkali burn what era MMP arrived at the busiest and MMP content and corneal ablation can simultaneously produce and what age use TIMP consequences best there is no clear conclusion. This experiment through the process to establish a big rat corneal alkali burn model to observations after alkali burn in different time of corneal MMP 1 and its restraining agent expression, understand the difference in after alkali burn cornea ablation in the course of action, in order to for clinical reasonable use of TIMP to prevent corneal ulcer for actual according to need. The test plant of Ankang SD big 35 rats. Rabbit anti - big rat MMP 1 polyclonal antibody and Goat anti - Big Rats TMMP a 1 polyclonal antibody and peroxidase Goat anti rabbit IgG and Rabbit anti goat IgG and SP kit with important reagents and equipments, the immune group of computer image analysis system. Test methods of experimental group rats to establish a model of corneal alkali burn. After alkali burns according to test packets at the death of rats were taken for HE and agile, backward immunohistochemical detection of MMP 1 and TIMP 1 in different expression and alteration after alkali burn cornea of the era. Over the same period by fluorescein staining, in the slit lamp observation of corneal shape changes. Results the expression of MMP4 and its inhibitors in normal rat cornea. 1 day after experimental brain injury, corneal epithelium missing, matrix fiber swelling thickening, limbal emerge in large numbers of inflammator the 4J day stromal ulceration gradually deepened, large quantity of inflammatory cell infiltration, emerging stroma bad died, burn after the 14 day ulcer of fastigium, corneal fire bad financial death reduced, inflammatory cell infiltra the Zi Mao 8 days, ulcer slowly repaired, visible fiber matrix adhesion. Immunohistochemical showed that MMPl after injury first days beginning 14 days decreased, reached the highest, then decreased trend, but still higher than the normal contrast. TIMP * late expression and thereafter activity was reduced gradually, day 14 after injury fell to lowest degree, later rising again, 21 days reached the highest. A discussion after alkali burn corneal ulcer very largely affect the results of protein hydrolase. In many protein hydrolase, the most important for the matrix metalloproteinases, referred to as MMPS. MMPs is in recent years to invent in the structure and function of the coherent containing zinc Endopeptidases family, based on differences in its structure and substrate effect. MMPs can be divided into a, medium MMP a after alkali burn of corneal ulcer constitute grew to have main effect. In recent years to invent a set of multiple effect factor family organization type matrix metal albumen enzyme restraint. TIMPS currently has invention of four members. The TIMP * for MMP of endogenous restraint, and activated the expression of MMP1 in a 1:1 ratio of joint and specific Baltic of its activity. OCM extracellular matrix (ECM) keep on the steady state has main effect. The mechanism of the expression of MMPI and its inhibitors detection of corneal tissue after alkali burn in contribute to a profound study of corneal alkali burn. The test by immunohistochemical methods and pathological image analysis system on the mmpl and TIMP related research notes, the expression of H in clinical pathological process after alkali burn differences within the time difference and and corneal ablation with synchronization. Through the study of.2.TIMP1 process for early prevention and treatment of alkali supply new way of corneal perforation after burn, with the potential value in the treatment of alkali burn. Part of the mechanism of MMP and TIMP * * activation and restraint, and for the prevention and treatment of corneal ulcer perforation to fair conditioning between the two balance pending further study. Conclusion 1, corneal ablation fastigium emerged in Fourteenth days after alkali burn. H, fourteenth days after alkali burn of MMPl excretion peak, TIMP1 excretion reached the lowest point. The clinical and pathological process of MMPl and TIMPd excretion 3, closely related to corneal ablation.目录:一、 中文摘要3-6二、 英文摘要6三、 英文缩略语10-11四、 前言11-12五、 实验材料12六、 实验方法12-14七、 实验结果(附论文图表)14-20八、 讨论20-24九、 结论24-25十、 本研究新见解25-26十一、 参考文献26-28十二、 致谢28-29十三、 综述29-40十四、 个人简介40-41十五、 在学期间发表论文41分享到:相关文献|&&&免费论文

编者按北京联盟 /眼表化学性烧伤是眼科常见的致盲性眼病,尤其是重度碱烧伤,治疗困难,预后极差,导致视力丧失,是临床上治疗非常棘手的难题,如何恢复患者的部分视功能,是目前急需解决的问题,在第15届全国角膜及眼表疾病学术大会暨第8届全国角膜屈光手术大会上,来自上海交通大学医学院附属第九人民医院的傅瑶教授与我们分享了1例双眼重度碱烧伤通过眼表重建和人工角膜移植后恢复光明的病例,提出了人工角膜的应用,给不适合接受常规角膜移植的患者带来复明的希望。北京联盟 /专家简介北京联盟 /北京联盟 /傅瑶,中华医学会眼科学分会青年委员、中华医学会眼科学分会角膜病学组委员,国家自然基金评审专家。主攻眼表疾病、角膜病和眼整形,擅长诊治难治性眼表疾病,尤其是对于严重睑球粘连患者,采用联合眼表重建和角膜移植手术方法,改善外观的同时达到增视的效果。发表论文30余篇,SCI收录10余篇;主持国家自然科学基金3项、上海市科委基础重点项目等5项。入选上海市浦江人才计划。北京联盟 /北京联盟 /病例介绍北京联盟 /北京联盟 /患者陈**,男,22岁,2012年6月不慎被“碱性物质”烧伤头面部及颈部,双眼失明,半年后来上海交通大学医学院附属第九人民医院就诊,诊断为双眼碱烧伤,右眼下睑缺损,右眼结膜囊狭窄,左眼睑缘融合状态(图1AB)。北京联盟 /北京联盟 /图1. 术前眼前节照片北京联盟 /北京联盟 /诊疗经过北京联盟 /北京联盟 /首先对患者进行了右眼眼睑重建和眼表重建,应用羊膜和口唇粘膜重建眼表基本结构(图2A),半年后再选择波士顿Ⅰ型人工角膜进行复明手术(图2B)。北京联盟 /术后早期视力即恢复到0.1。患者在人工角膜移植半年后出现镜后膜,予以YAG激光切除;术后一年发生了部分角膜植片溶解,经过板层角膜修补后维持稳定,随访2年视力维持在0.1。北京联盟 /北京联盟 /图2. 右眼眼表重建术后及人工角膜移植术后北京联盟 /北京联盟 /北京联盟 /讨论分析北京联盟 /北京联盟 /多年来,很多临床医生对眼部碱烧伤的治疗进行了各种不同类型的尝试,如结膜移植术、角膜移植术、角膜缘干细胞移植术及羊膜移植术等,但是由于眼表环境在碱烧伤过程中的破坏,此类治疗往往得不到满意的治疗效果。有文献报道,碱性化学伤传统的穿透性角膜移植长期透明率低于20%,尤其对于重度碱烧伤后并发严重角膜瘢痕血管化、广泛的结膜疤痕缩窄、睑球粘连及睑裂闭锁的患者,往往预后极差。因此对于此类患者首要的处理措施就是对患者的眼表进行重建,眼表状态相对稳定后可以考虑进一步进行人工角膜移植手术。1789年 法国眼科医生Guillaume Pellier de Quengsy 首次提出人工角膜(Keratoprosthesis,Kpro)的概念,目前全世界应用较广泛的人工角膜有Boston人工角膜、骨齿型人工角膜(OOKP)等。Boston-Kpro随着设计的改进,适应证越来越广。其主要结构是由一个前板,一个后板以及中间连接的镜柱构成,镜柱材料为聚甲基丙烯酸甲酯(polymethyl methacrylate,PMMA),后板通过C型钛环可以锁紧,而整个人工角膜需要安装存一片新鲜的供体角膜片上(图3)。截止目前波士顿Ⅰ型人工角膜已在全球累计使用超过9000例,给许多失明的患者带来了光明,文献报导45%~89% 的患者术后视力(BCSVA) 20/200;留存率 65%~100%(随访2~47月)。北京联盟 /北京联盟 /图3. Boston-Kpro原理北京联盟 /北京联盟 /本例患者,青年男性,双眼重度碱烧伤后半年,初诊时已经发生双眼结膜闭锁,眼表环境极差,应用羊膜和口唇黏膜行眼表重建后,双眼视力可以达到眼前手动,但是平日走路需要家人搀扶,无法自理。由于患者双眼角膜已瘢痕化结膜化,大量新生血管长入其中,传统的穿透性角膜移植术成功的可能性很小。综合考虑上述因素,选择对其使用波士顿Ⅰ型人工角膜移植术来尝试使患者复明,以期能够使患者获得一个较好的生活状态。术后随访2年结果显示人工角膜植片维持稳定,右眼视力从眼前手动提高到0.1,患者的生活状态从完全不能自理到生活自理甚至看书写字。北京联盟 /因此,重度碱烧伤造成严重的眼表角膜结构功能破坏后可通过眼表重建和人工角膜移植恢复部分视功能,但眼表的状态和稳定仍是人工角膜留存和成功的关键因素。同时,人工角膜也有很高的几率发生较为严重的并发症,如角膜溶解以及眼内炎等,这些并发症处理较为棘手,因此人工角膜移植需要掌握严格的指征,选择仍需慎重。北京联盟 /
