目的:观察不同类型慢性根尖周病组织中肥大细胞( mast cells, MCs)的分布情况,并分析白细胞介素1β(interleukin-1β,IL-1β)和白细胞介素17(interleukin-17,IL-17)在MCs上的表达情况,探讨MCs IL-1β和IL-17在根尖周病发病机制中的作用。方法:本实验共收集102例样本,分为3组:(1)根尖肉芽肿组32例;(2)根尖囊肿组35例;(3)正常对照组35例。组织标本经4%中性甲醛缓冲液固定48 h以上;石蜡包埋,组织连续切片,HE染色,在光学显微镜下观察其组织学改变;采用免疫荧光双染色法,在荧光显微镜下观察各组标本组织表达IL-1β和IL-17的MCs数目。结果:两组慢性根尖周病的炎症反应程度明显高于正常对照组( P<0.01);根尖囊肿组与根尖肉芽肿组之间炎症反应程度无显著差异(P>0.05)。与正常对照组相比,两组慢性根尖周病组织中IL-1β和IL-17阳性MCs数目均显著增多(P<0.01);根尖囊肿组与根尖肉芽肿组IL-1β和IL-17阳性MCs密度无显著性差异(P>0.05)。经Pearson相关分析,3组标本组织中IL-1β和IL-17阳性MCs密度与组织炎症反应程度存在直线的正相关关系(P<0.01)。结论:慢性根尖周病组织中MCs数目明显增多,同时IL-1β和IL-17阳性的MCs密度显著增高。 IL-1β和IL-17阳性MCs密度与根尖周病的炎症程度趋势相一致。这提示IL-1β和IL-17阳性MCs可能在慢性根尖周病的致病机制中发挥重要作用。
目的:觀察不同類型慢性根尖週病組織中肥大細胞( mast cells, MCs)的分佈情況,併分析白細胞介素1β(interleukin-1β,IL-1β)和白細胞介素17(interleukin-17,IL-17)在MCs上的錶達情況,探討MCs IL-1β和IL-17在根尖週病髮病機製中的作用。方法:本實驗共收集102例樣本,分為3組:(1)根尖肉芽腫組32例;(2)根尖囊腫組35例;(3)正常對照組35例。組織標本經4%中性甲醛緩遲液固定48 h以上;石蠟包埋,組織連續切片,HE染色,在光學顯微鏡下觀察其組織學改變;採用免疫熒光雙染色法,在熒光顯微鏡下觀察各組標本組織錶達IL-1β和IL-17的MCs數目。結果:兩組慢性根尖週病的炎癥反應程度明顯高于正常對照組( P<0.01);根尖囊腫組與根尖肉芽腫組之間炎癥反應程度無顯著差異(P>0.05)。與正常對照組相比,兩組慢性根尖週病組織中IL-1β和IL-17暘性MCs數目均顯著增多(P<0.01);根尖囊腫組與根尖肉芽腫組IL-1β和IL-17暘性MCs密度無顯著性差異(P>0.05)。經Pearson相關分析,3組標本組織中IL-1β和IL-17暘性MCs密度與組織炎癥反應程度存在直線的正相關關繫(P<0.01)。結論:慢性根尖週病組織中MCs數目明顯增多,同時IL-1β和IL-17暘性的MCs密度顯著增高。 IL-1β和IL-17暘性MCs密度與根尖週病的炎癥程度趨勢相一緻。這提示IL-1β和IL-17暘性MCs可能在慢性根尖週病的緻病機製中髮揮重要作用。

AIM:To identify and quantify the expression of IL-1βand IL-17 in mast cells ( MCs) in different types of human pericapical diseases using double immunofluorescence staining .METHODS: The specimens ( n=102 ) , including healthy control ( n=35 ) , periapical cyst ( n=35 ) and periapical granuloma ( n=32 ) , were involved in the present study .The tissue samples were fixed in 10% buffered formalin for at least 48 h and then embedded in paraffin . Serial 5-μm-thick sections were deposited onto SuperFrost/Plus microscope glasses .Routine staining of the sections using hematoxylin&eosin ( HE) was performed for morphological evaluation .The number of IL-1βand IL-17 positive MCs was identified by double immunofluorescence staining .RESULTS:Compared with the healthy controls , the inflammation score of periapical lesions was significantly increased in the periapical patients (P<0.01).The density of IL-1βand IL-17 posi-tive MCs in the periapical lesions were obviously higher than that in the healthy controls (P<0.01).However, no signifi-cant difference between periapical cyst and periapical granuloma was observed .The Pearson correlation analysis showed that there was a positive correlation between the density of IL-1βand IL-17 double positive MCs and inflammation score in dif-ferent groups of specimens (P<0.01).CONCLUSION:There is significantly increased number of MCs , along with in-creased density of IL-1βand IL-17 positive MCs in human periapical lesions .The increased density of IL-1βand IL-17 positive MCs has the similar tendency as the severity of tissue inflammation in human periapical lesions , suggesting that IL-1βand IL-17 positive MCs may play an important role in the pathogenesis of human periapical diseases .
