目的研究糖皮质激素受体( glucocorticoid receptor ,GR)亚型α和β在口腔扁平苔藓( oral li-chen planus ,OLP)中的表达特点,探讨GR与OLP发生及临床分型的关系。方法分别采用RT-PCR和免疫组化法检测GR亚型α和β在32例OLP患者(斑纹型18例,糜烂型14例)局部病损口腔黏膜和12例健康口腔黏膜的表达情况,并分析GRα/GRβ比值的差异。结果 GRα和GRβ均主要表达于OLP角质形成细胞。 OLP病变口腔黏膜中GRαmRNA的表达水平降低( P=0.000),GRα/GRβ比值下降( P=0.000),而GRβmRNA的表达水平与健康对照组无统计学差异( P=0.07)。 GRαmRNA、GRβmRNA及GRα/GRβ比值在斑纹型和糜烂型OLP中的表达均无统计学差异(分别为P=0.263,P=0.729,P=0.150)。结论 OLP中GR主要表达于局部病损区的角质形成细胞,GR亚型表达改变可能与OLP局部病损的发生有关。此外,GR亚型的表达水平可能与OLP病情的严重程度无关。
目的研究糖皮質激素受體( glucocorticoid receptor ,GR)亞型α和β在口腔扁平苔蘚( oral li-chen planus ,OLP)中的錶達特點,探討GR與OLP髮生及臨床分型的關繫。方法分彆採用RT-PCR和免疫組化法檢測GR亞型α和β在32例OLP患者(斑紋型18例,糜爛型14例)跼部病損口腔黏膜和12例健康口腔黏膜的錶達情況,併分析GRα/GRβ比值的差異。結果 GRα和GRβ均主要錶達于OLP角質形成細胞。 OLP病變口腔黏膜中GRαmRNA的錶達水平降低( P=0.000),GRα/GRβ比值下降( P=0.000),而GRβmRNA的錶達水平與健康對照組無統計學差異( P=0.07)。 GRαmRNA、GRβmRNA及GRα/GRβ比值在斑紋型和糜爛型OLP中的錶達均無統計學差異(分彆為P=0.263,P=0.729,P=0.150)。結論 OLP中GR主要錶達于跼部病損區的角質形成細胞,GR亞型錶達改變可能與OLP跼部病損的髮生有關。此外,GR亞型的錶達水平可能與OLP病情的嚴重程度無關。

Objective To investigate the expression characteristic of glucocorticoid receptor ( GR) isoformsαandβon oral lichen planus ( OLP) and the correlation with morbidity and clinical forms .Methods Thirty-two OLP cases ( including 18 cases of reticular-plaque forms and 14 cases of erosive forms ) and 12 normal subjects were selected.The excisional oral mucosae were detected for glucocorticoid receptor isoforms and their ratio by RT -PCR and IHC.Results Both GRαand GRβstaining were found mainly in epithelial keratinocytes of OLP .The expression of GRαmRNA was significantly lower in OLP than that in normal tissues ( P=0.000 ) .So was the ratio of GRαand GRβ( P=0.000 ) .But no differences of GRβmRNA were detected between OLP and normal samples ( P=0.473 ) . And the expression of GRαmRNA and GRβmRNA, and the ratio of GRαand GRβhad no differences between reticular-plaque forms and erosive forms of OLP ( P=0.263 ,0.729 ,0.150 respectively ) .Conclusion GR mainly expresses in the keratinocyte of OLP ,and the change of GR isoforms may closely correlated with occurrence of OLP . Moreover ,the expression of GR isoforms may be not associate with severity of OLP .
