The World Health Organization classifies DMPM into three types： epithelioid, sarcomatoid, and biphasic types. DMPM remains suffering poor prognosis and the diagnosis should always be based on adequate, representative tissue samples. There still remains a considerable number of patients with DMPM who are misdiagnosed after a complete investigation including thoracoscopic biopsies.展开更多
文摘将34只C57BL/6小鼠随机分成4组:正常对照组(PBS组,n=5)、假手术对照组(Sham组,n=5)、脓毒症组(CLP组,n=12)以及坏死细胞处理组(Nec组,n=12)。PBS组为正常小鼠,腹腔注射200μL的PBS 1次,Sham组小鼠手术分离盲肠末端后,不进行结扎穿孔;CLP组小鼠用盲肠结扎穿孔法(Cecal ligation and puncture,CLP)建立脓毒症模型;Nec组小鼠预先腹腔注射2×107个坏死细胞,第0天再行盲肠结扎穿孔。所有小鼠于制备CLP模型后2周处死,流式细胞仪检测外周血、脾脏和胸腺中CD4+IFN-γ+Th1细胞以及CD4+IL-4+Th2细胞比例。结果显示,CLP组小鼠外周血Th1/Th2比例显著高于Sham组及PBS组(P<0.05),同时脾脏中Th1/Th2比例则低于Sham组(P<0.01)。Nec组小鼠外周血Th1/CD4+T细胞比例及Th1/Th2比例显著低于CLP组(P<0.05),但脾脏中Th1/Th2比例则显著高于CLP组(P<0.01)。结果表明,预先输注坏死细胞可以逆转脓毒症小鼠体内Th1/Th2比例失衡。
