文题释义:

辅酶Q10:它以泛醌的形式广泛存在于所有的生物膜中,是结构类似于脂溶性维生素类化合物。正常情况下,所有细胞都可以通过自身合成来满足对辅酶Q10的生理需要水平。目前经研究已知的辅酶Q10的功能包括参与呼吸链电子传递,还原态辅酶Q10具有重要的抗氧化功能,减少细胞的凋亡,增强免疫系统的抗炎功能。

白细胞介素:是由多种细胞产生并作用于多种细胞的一类细胞因子。最初指由白细胞产生又在白细胞间起调节作用的细胞因子。目前至少发现了38个白细胞介素,其功能复杂,成网络,复杂重叠。白细胞介素在传递信息,激活与调节免疫细胞,介导T、B细胞活化、增殖与分化及在炎症反应中起重要作用,此外它们还参与机体的多种生理及病理反应。 

 

背景:辅酶Q10参与呼吸链的电子传递,具有抗氧化、减少细胞凋亡和抗炎的功能,已经在心血管病、糖尿病、肿瘤等方面取得了良好的效果,在糖尿病牙周炎领域的应用可能也具有一定的应用价值。

目的:观察伴2型糖尿病牙周炎大鼠牙龈组织白细胞介素17及白细胞介素23表达的变化。

方法:将48只Wistar健康雄性大鼠随机分为3组:空白对照组,牙周炎+糖尿病+生理盐水组,牙周炎+糖尿病+辅酶Q10组。空白对照组正常饮食,其他2组采用丝线结扎的方法建立伴牙周炎模型,采用高脂高糖饮食+腹腔注射链脲佐菌素的方法建立2型糖尿病模型。造模成功后辅酶Q10组大鼠连续8周灌胃辅酶Q10,生理盐水组大鼠给同等剂量的生理盐水,分别于给药前,给药第2,4,8周末随机处死4只,采用免疫组织化学法检测牙龈组织中白细胞介素17及白细胞介素23表达水平。

结果与结论:第8周末,生理盐水组白细胞介素17、白细胞介素23的阳性表达率显著高于辅酶Q10组(P < 0.05)。辅酶Q10可以降低伴2型糖尿病牙周炎大鼠牙龈组织白细胞介素17、白细胞介素23的表达,减轻牙周组织炎症反应。

Abstract:

BACKGROUND: Coenzyme Q10 participates in the electron transport of respiratory chain and possesses antioxidant, anti-apoptotic and anti-inflammatory properties. It has achieved good outcomes in cardiovascular disease, diabetes and cancer. Coenzyme Q10 may also have a certain application value in the fields of diabetes and periodontitis.
OBJECTIVE: To observe the effect of coenzyme Q10 on the expression of interleukin-17 and interleukin-23 in gingival tissue of type 2 diabetic rats with periodontitis. 
METHODS: Forty-eight healthy male Wistar rats were randomly divided into 3 groups: control, periodontitis+ diabetes+physiological saline and periodontitis+diabetes+coenzyme Q10. Rats in the control group were fed with normal diet and water. Rats in the periodontitis+diabetes+physiological saline and periodontitis+diabetes+ coenzyme Q10 groups were subjected to induction of periodontitis using the method of silk ligation and type 2 diabetes by feeding a high-fat and high-sugar diet and intraperitoneal injection of streptozotocin. After successful modeling, rats in the periodontitis+diabetes+coenzyme Q10 group were intragastrically administered coenzyme Q10 for 8 successive weeks. Rats in the periodontitis+diabetes+physiological saline group were administered equal amount of physiological saline. At the end of 2nd, 4th and 8th weeks after drug administration, four rats were randomly selected and sacrificed. The expression levels of interleukin-17 and interleukin-23 in gingival tissue were detected by immunohistochemistry.
RESULTS AND CONCLUSION: At the end of 8th week, interleukin-17- and interleukin-23-positive expression in the periodontitis+diabetes+physiological saline group was significantly higher than that in the periodontitis+ diabetes+coenzyme Q10 group (P < 0.05). Coenzyme Q10 can reduce the expression levels of interleukin-17 and interleukin-23 in gingival tissue of type 2 diabetic rats with periodontitis, and alleviate periodontal tissue inflammation of type 2 diabetic rats with periodontitis.
