目的:观察磷脂酰肌醇3激酶(PI3K)特异性抑制剂LY294002对CD3mAb活化的T细胞及Mtb-Ag激活γδT细胞的影响,探讨PI3K在CD3mAb活化的T细胞及Mtb-Ag启动的γδT细胞TCR途径信号转导中作用.方法:分离获取健康人外周血单个核细胞(PBMC),用CD3mAb(CD3单克隆抗体)、PMA+IM(佛波醇酯+离子霉素)、Mtb-Ag(结核杆菌低分子多肽抗原)刺激PBMC,采用流式细胞术检测CD3+T细胞和γδT细胞不同时间的CD69分子的表达情况;PBMC经LY294002处理后再刺激培养,用CD3PE/CD69FITC、γδPE/CD69FITC双染后,检测CD3+T细胞和γδT细胞CD69的表达情况;计数培养扩增10天的细胞数量.

目的:观察溃肠宁治疗溃疡性结肠炎的临床疗效.方法:将64例患者按就诊顺序分为治疗组34例、对照组30例,治疗组予溃肠宁口服并灌肠;对照组口服柳氮磺吡啶肠溶片.疗程均10周.结果:在诱导缓解率、证候改善有效率、症状体征改善、安全性、远期疗效方面,治疗组优于对照组(P<0.05).结论:溃肠宁多靶点治疗溃疡性结肠炎脾胃虚弱夹湿热、肝郁、血瘀证型的效果较单纯西药治疗佳,值得进一步研究及临床推广.

溃疡性结肠炎为现代难治性疾病之一,属中医"痢疾"、"泄泻"和"腹痛"范畴,潘洋教授根据多年临床经验运用中医辨证论治理论,认为本病辨证应以虚实为纲,实证以湿热下注为主,虚证以脾肾阳虚为主,确立清热化湿,益气健脾,温阳补肾,止血生肌为治则,采用中药内服配合中药灌肠的方法治疗溃疡性结肠炎,经大量临床观察疗效显著、具有毒副作用小、复发率低的优势。
