简介：【 摘要】 目的 : 探讨白介素 － 6( IL- 6 ) ， 白介素 － 8( IL－ 8 ) 与胎膜早破 的关系 。 方法 : 收集 2018年 1月 -2019年 1月的 160例胎膜早破孕妇作为病例组 ; 随机抽取同期正常孕妇160例作为对照组 。 两组孕妇入院后即抽取静脉血提 取血清 ，采用 ELISA 法检测血清中IL－ 6 、IL－ 8的含量 ，统计分析病例组和对照组感染绒毛膜羊膜炎的几率 ，采用 western blot 测定胎盘组织中 IL－ 6 、IL－ 8含量 。结果 : 病例组血清中 IL－ 6 ,IL－ 8 的含量明显高于对照组 , 差异有统计学意义 ;病例组感染绒毛膜羊膜炎的几率明显高于对照组 ， 差异有统计学意义 ; 结论 :IL－ 6 ,IL－ 8 可能全程参与妊娠过程 ，因此联合监测 IL－ 6 、IL－ 8 的含量对于预测胎膜早破新生儿的预后有一定的作用 ， 尤其在降低新生儿死亡率 、预防远期并发症等方面有一定价值 。

简介：目的:分析过敏性鼻炎(allergic rhinitis，AR)患者外周血CD4 ＋Th17细胞中IL-18、IL-18结合蛋白a(IL-18-binding protein a, IL-18BPa)和IL-18受体α(IL-18 receptor α，IL-18Rα)的表达水平及过敏原对其表达的影响。 方法:选择2019年10月—2020年9月锦州医科大学附属第一医院过敏反应科门诊AR患者45例和该医院体检中心体检者23例(健康对照组)为研究对象。根据皮肤点刺试验结果，将患者分为阳性组(AR组，24例)和阴性组(nAR组，21例)。收集受试者血液样本，流式细胞术检测过敏原对CD4 ＋Th17细胞中IL-18、IL-18BPa和IL-18Rα蛋白质表达水平的影响。Bioplex检测血浆中IL-17A水平，并分析其与IL-18 ＋Th17细胞比例的相关性。 结果:与健康对照组比较，AR组患者CD4 ＋Th17细胞和IL-18 ＋Th17细胞比例均增加( P<0.01)，IL-18BPa ＋Th17细胞比例降低( P

简介：【摘要】康复新液是一种通利血脉，养阴生肌的纯中药制剂。临床可辅助胃黏膜修复，但其副作用尚不清楚。我们将康复新液用于2例由于痛风长期服用非甾体消炎药所致的胃溃疡患者，偶然间发现康复新液诱发了痛风性关节炎的急性发作。回顾病史及查阅文献，我们猜测可能是由于其昆虫成分增加血尿酸有关。本病案记载了康复新液的潜在不良反应，为临床其相关禁忌症提供参考。
