J Clin Periodontol:慢性牙周炎与血小板因子4(PF4)分泌相关

2017-10-28 MedSci MedSci原创

血小板与慢性炎症相关,但它们在牙周炎中的作用尚不清楚。本研究的目的是比较健康和炎性牙周组织中的血小板募集和激活。

血小板与慢性炎症相关,但它们在牙周炎中的作用尚不清楚。本研究的目的是比较健康和炎性牙周组织中的血小板募集和激活。

从健康牙周组织,牙龈炎和牙周炎的位点获取龈沟液(GCF)样本。通过染色和显微镜定量测定GCF中的血小板。通过ELISA测定GCF中血小板因子4(PF4)[PF4] GCF和糖蛋白IIbIIIa([GPIIbIIIa] GCF)的浓度。从三个患者组获取血液样本。从全血中分离血小板并用来自牙龈卟啉单胞菌的脂多糖(LPS)进行刺激,以评估和比较LPS诱导的PF4释放。与对照组相比,基于血小板计数和[GPIIbIIIa] GCF,牙龈炎和牙周炎位点的血小板募集增加。 [PF4] GCF在牙周袋中升高,但牙龈炎或健康位点没有升高。广泛性牙周炎(SP)患者的PF4循环血浆水平较牙龈炎或健康牙周者高。牙龈卟啉菌LPS诱导下,从SP患者分离的血小板中比牙龈炎或牙周健康患者含有并释放更多的PF4。

结论:牙周炎与局部和全身的血小板激活和PF4释放增加有关。

Arch Oral Biol:新型壳聚糖-二甲双胍复合物可有效治疗牙周炎

本研究旨在研发一种基于壳聚糖-二甲双胍的嵌入式牙膜(CMIDF),用于治疗牙周炎及牙周炎所致的牙槽骨丧失。通过溶剂铸造技术制造CMIDF嵌入物,并对其进行物理特性评估,例如折叠耐力,表面pH,粘膜粘附强度,二甲双胍含量均匀性和释放情况。结果显示,在壳聚糖存在下,X射线衍射分析显示二甲双胍无结晶,证实二甲双胍成功地嵌入至CMIDF。傅里叶变换红外光谱显示,CMIDF的稳定性较好,二甲双胍和壳聚糖之间

研究进一步揭示肥胖与牙周炎关联的潜在机制

世界范围内,肥胖症是非常普遍的慢性疾病,可增加牙周炎的易感性。本文旨在提供肥胖与牙周病之间关联的系统评价,并确定这种关系的潜在的机制。研究人员检索了PubMed-Medline和Embase数据库中相关文祥,选择对照临床试验和观察性研究,确定牙周和身体组成参数。对每篇文章都进行了数据提取和质量评估。结果共检索了284篇相关文章,预选纳入其中64篇,最终纳入28篇文献进行审查。除了两篇文章显示没有关

虾青素是具有很强抗氧化作用的酮类胡萝卜素。本研究旨在评估虾青素对结扎诱导的牙周炎大鼠牙槽骨丢失和组织病理学变化的影响。将Wistar大鼠分为4个实验组:未结扎(C,n = 6);仅结扎(L,n = 6);结扎和虾青素(1mg/kg/天虾青素,AS1组,n = 8);结扎和虾青素(5mg/kg/天虾青素,AS5组,n = 8)。丝线结扎部位为下颌第一磨牙。研究时间为11天,结束后处死大鼠。临床评估牙

Biosci Rep:IL-12介导的人牙周膜细胞MMPs的表达涉及NF-κB的活化

白介素(IL-12)是一种促炎细胞因子,其水平的增加与牙周炎的严重程度相关。然而,IL-12在牙周病变发病机制中的作用是有争议的,目前尚未得到充分的阐明。本研究旨在研究IL-12是否影响人牙周膜成纤维细胞(hPDLFs)中基质金属蛋白酶(MMPs)和金属蛋白酶组织抑制剂(TIMP)的表达。使用IL-12处理hPDLFs不同时间后,分别采用实时荧光定量PCR和蛋白质印迹法检测MMP-1,MMP-2,
