目的:探讨溃疡性结肠炎(UC)患者肠道菌群分布和种类的变化及其与白细胞介素23(IL-23)/IL-17轴的关系。方法 :收集20例UC活动期患者和20例健康对照者的新鲜粪便标本,采用直接涂片镜检和传统细菌培养鉴定法分析菌群分布;利用real-time PCR检测菌群种类的变化;常规检测血红蛋白、白蛋白、血沉和C反应蛋白水平;经结肠镜活检取UC患者正常及病变肠黏膜组织,进行Mayo评分和Baron分级,HE染色观察组织病理变化;免疫组化及Western Blot观察IL-17和IL-23表达的改变。结果:(1)与对照组比,活动期UC患者菌群失调程度明显升高(P<0.05);(2)需氧培养结果表明,活动期UC患者的大肠杆菌数量较正常人显著降低(P<0.01),肠球菌数量明显增加(P<0.01);厌氧培养结果发现,活动期UC患者的拟杆菌、双歧杆菌和乳酸杆菌数量较正常人显著减少(P<0.01);(3)目标菌属定量分析表明,UC患者粪便中大肠杆菌、拟杆菌、双歧杆菌和乳酸杆菌相对定量较正常人显著降低,肠球菌数量明显升高(P<0.01);(4)与对照组相比,UC患者血红蛋白无明显改变,白蛋白明显降低(P<0.05),血沉和C反应蛋白明显增高(P<0.01);(5)UC患者Mayo评分显著升高(P<0.01),Baron分级显著增加(P<0.01),结肠组织病理改变明显(P<0.01);(6)与对照组比较,UC患者表达丰富的IL-17和IL-23(P<0.01);(7)相关性分析表明,IL-17和IL-23表达的平均吸光度与Baron分级(r=0.717,P=0.02;r=0.849,P=0.016)和病理组织学评分(r=0.660,P=0.030;r=0.675,P=0.032)呈正相关;同时,IL-23表达的平均吸光度与大肠杆菌数量呈明显负相关(r=-0.669,P=0.025),与肠球菌数量呈正相关(r=0.872,P=0.010),IL-17表达的平均灰度值与肠球菌数量呈正相关(r=0.764,P=0.046),但二者与其它目标菌属的数量无明显相关性。结论:活动期UC患者存在明显的肠道菌群失调,改变的细菌与患者炎症程度密切相关。IL-23/IL-17轴作为UC发生发展的关键因子,与肠道菌群含量的变化可能存在一定关联,其相互作用在UC的病理过程中起到重要作用。

辣椒(Capsicum annuum)是美洲最古老的驯化作物之一,在全世界被广泛种植。本研究对CM334(墨西哥地方品种)进行了全基因组测序和组装(覆盖度为186.6×),同时还对另外两个栽培种和一个野生种分别进行了重测序和从头(de novo)测序。结果表明辣椒基因组大小约为番茄的4倍,辣椒基因组上存在大量gypsy转座子和花椰菜病毒家族元件的积累。结合转录组综合分析认为,辣椒素合成酶基因表达模式的改变及新功能化是导致辣椒素生物合成的原因,研究还发现辣椒与番茄在乙烯合成及果实成熟调控方面存在明显不同的分子模式。辣椒参考基因组的发布为辣椒营养品质和药用价值的改善提供了重要平台。

为了防止智齿拔除后并发症的发生,采用临床研究的方法,选择双侧下颌第3磨牙阻生的病人65例,按牙位随机分为3组。拔除阻生牙后,第1组在拔牙窝内,放置口腔组织补片;第2组放置骨粉和口腔组织补片;第3组为空白对照组。观察术后近期和远期并发症。结果显示,两组都不同程度地减少了拔牙后近期和远期并发症,但第2组能更加有效地减轻磨牙拔除后牙槽骨吸收。说明引导骨组织再生术有助于保持患牙相邻磨牙长期稳定,提高咀嚼效率以及保持牙槽嵴的原有形态。
