烟曲霉致病相关因子的研究进展

毒力因子是在病原体适应生存环境的过程中产生.烟曲霉毒力是多因素相关的,包括微小的孢子结构使之能够吸入到达宿主的肺泡,耐热特征,疏水性,快速的繁殖速度以及抵抗氧化应激反应的能力.此外,烟曲霉适应环境及代谢相关的蛋白、通路信号分子、脂类代谢产物、毒素等均可看作毒力因子.     

舌正中岛状瓣修复口底缺损

目的：总结应用舌正中岛状瓣修复口底缺损的经验。方法：5例中小型口底缺损患者采用舌正中岛状瓣修复重建。在舌背正中部位制备舌肌黏膜瓣,通过切开舌尖或舌组织隧道以岛状瓣的方式转移修复口底缺损。结果：5例患者术后舌瓣均成活良好,无舌瓣坏死,1例术后一侧舌尖部分坏死。术后随访3-6个月,患者发音及吞咽功能无明显异常。结论：舌正中岛状瓣是一种修复中小型口底缺损的好方法。     

面动脉岛状肌皮瓣修复舌癌术后组织缺损12例

目的:探讨下颌下区面动脉岛状肌皮瓣修复舌癌根治术后组织缺损的可靠性及效果。方法 :选择2009-01—2012-01,韶关市第一人民医院口腔颌面外科收治的舌癌患者12例,其中男性7例,女性5例,全部采用下颌下区面动脉岛状肌皮瓣同期修复舌癌根治性切除术后半舌缺损,术后观察组织瓣成活情况、外形和功能、患者的生存状态以及癌瘤复发等情况。结果:12例患者中,皮瓣完全成活11例,1例皮瓣部分坏死。术后随访6～36个月,患者舌部皮瓣形态、质地良好,语言及吞咽功能理想。1例患者出现颈部肿瘤复发。结论:下颌下区面动脉岛状肌皮瓣可作为半舌缺损修复较理想的皮瓣,该术式简单,易成功,适合同期修复舌癌根治术后半舌缺损。     

粪肠球菌主要毒力因子研究进展

粪肠球菌为条件性致病菌,是许多国家医院内感染的主要病原菌,也是一种新的人畜共患病病原体。粪肠球菌感染和致死主要是由其毒力因子引起的,本文概述了粪肠球菌主要毒力因子尤其是溶血素的研究进展,为粪肠球菌致病机制的研究奠定基础。     

颏下岛状皮瓣在舌癌术后组织缺损修复中的临床应用

目的：总结颏下岛状皮瓣修复舌癌术后组织缺损的临床经验。方法：对我科收治的11例舌癌术后缺损患者进行颏下岛状瓣修复,其中男性7例,女性4例,全部病例行舌癌扩大切除术,舌缺损采用颏下动脉岛状皮瓣同期修复。术后观察组织瓣生长情况以及修复效果。结果：10例皮瓣存活,皮瓣形态自然美观,舌活动灵活,基本恢复解剖形态和生理功能。术后随访12个月,未发现复发和转移。1例男性患者组织瓣上有胡须生长。1例出现皮瓣远端部分坏死,二期愈合。结论：应用颏下岛状皮瓣修复舌癌术后缺损操作简单,修复效果良好,是一种有效的修复方法。     

IDIOPATHIC ISOLATED BILATERALLY SYMMETRICAL BRACHYMETACARPIA OF THE FIFTH METACARPAL: Case report

We report a rare case of a 32-year-old woman with idiopathic isolated bilaterally symmetrical brachymetacarpia of the fifth metacarpal bone, which had been present since the age of 14. Movement, and sensory and motor function were within normal limits, and she had no symptoms. No treatment was recommended. We know of no similar case reports.     

Lactobacillus fermentum,a pathogen in documented cholecystitis

INTRODUCTIONLactobacillus species are probiotics proven to exhibit various preventative as well as therapeutic properties. While lactobacillus species have been implicated in the formation of dental caries, endocarditis and bacteremia, their role as pathogens in cholecystitis has not been reported. We present a rare case of Lactobacillus fermentum working as a pathogen in cholecystitis.PRESENTATION OF CASEAn 81-year old male was admitted with right upper quadrant abdominal pain. His signs, symptoms, laboratory values and imaging were consistent with a diagnosis of cholecystitis with ascending cholangitis. In view of his co-morbidity and severe sepsis, the patient was treated non-operatively with antibiotics and cholecystostomy. L. fermentum, which was vancomycin resistant, was identified from the cholecystostomy aspirate and from anaerobic blood culture. The patient went into septic shock, developed multi-organ dysfunction syndrome and eventually died.DISCUSSIONCommensal bacteria such as L. fermentum are known to modulate immunity, reduce the pathogenicity of gastrointestinal organisms and play a therapeutic role in various disease processes. We isolated L. fermentum as a pathogen in a documented case of cholecystitis with ascending cholangitis.CONCLUSIONWhile the routine use lactobacillus species as a probiotic is supported in the literature, understanding its potential role as a pathogen may allow more judicious use of these bacteria and encourage research to elucidate the pathogenicity of lactobacillus species.     

指背逆行岛状皮瓣修复指端软组织缺损

目的探讨指背逆行岛状皮瓣修复指端软组织缺损的手术方法及疗效。方法 2010年1月~2015年4月,应用指背逆行岛状皮瓣修复指端软组织缺损41例45指,其中男性32例,女性9例;年龄17~57岁,平均37岁。41例患者45指均有指骨外露,缺损面积1.8cm×1.5cm~3.0cm×2.5cm。皮瓣切取范围2.0cm×1.8cm~3.2cm×2.8cm。皮瓣旋转点于远指间关节以近,逆行旋转覆盖指端缺损区。结果 45指皮瓣均成活。39指随访5~20个月,平均12.5个月,皮瓣颜色、皮肤质地及弹性良好,外形佳,皮瓣两点辨别觉为8~10mm,皮瓣供区外观满意,手指运动功能满意。结论指背逆行岛状皮瓣手术操作简单,不伤及指间动脉及神经,血管蒂长,皮瓣蒂携带皮条,旋转弧度大,成功率高,疗效满意,是修复指端软组织缺损的有效方法之一。
