摘要 目的探讨慢性风湿性心脏病(RHD)患者心脏二尖瓣瓣膜上Th17细胞轴相关细胞因子白细胞介素(IL)-17、IL-21、IL-6、IL-23表达水平的改变。方法选择20例RHD患者及12例非RHD对照组二尖瓣瓣膜组织(NRHD组),应用苏木素-伊红(HE)染色和免疫组化法对IL-17、IL-21、IL-6、IL-23表达水平进行检测。结果 RHD组HE染色可见瓣膜组织部分出现纤维化和钙化,局灶性散在的慢性炎性细胞浸润,以淋巴细胞、浆细胞为主。免疫组织化学染色可见慢性炎性细胞、成纤维细胞、血管内皮细胞存在IL-17、IL-21、IL-6、IL23的表达且定位于细胞质中,炎性细胞主要位于血管旁。RHD组IL-17、IL-21、IL-6、IL23表达阳性细胞比例及其乘积评分均明显高于NRHD组(P<0.05)。结论 RHD患者瓣膜中Th17细胞相关细胞因子的表达明显增高,高Th17表达可能是引起RHD持续瓣膜损害的一个潜在机制。
