Peritoneal loose bodies are usually small, white or pale gray, pea-shaped objects with a smooth glistening surface, oecasionally found during laparotomy or autop-sy. They usually lie free in the peritoneal cavity, 0.5 - 2.5 cm in diameter. We reported herein a case of a giant loose body measuring 9.5 cm, and discussed how such a large mass can develop and the related problems.展开更多
目的探讨不同时间点内毒素(LPS)对CD4+CD25+调节性T细胞(CD4+CD25+regulatory T cell,Treg)的影响及连翘(forsythia suspensa,FS)干预后CD4+CD25+调节性T细胞的变化。方法体外培养Wistar大鼠脾脏淋巴细胞,分为对照组、LPS(10ng/ml)组、L...目的探讨不同时间点内毒素(LPS)对CD4+CD25+调节性T细胞(CD4+CD25+regulatory T cell,Treg)的影响及连翘(forsythia suspensa,FS)干预后CD4+CD25+调节性T细胞的变化。方法体外培养Wistar大鼠脾脏淋巴细胞,分为对照组、LPS(10ng/ml)组、LPS(10ng/ml)+多黏菌素B组(10μg/ml)、LPS(10ng/ml)+连翘(12.5、25、50mg/ml)组,分别于3、6、12h收集标本,流式细胞术检测CD4+CD25+调节性T细胞在淋巴细胞中的百分比,荧光定量RT-PCR法检测Foxp3mRNA表达,酶联免疫吸附试验(ELISA)法检测TNF-α、IL-10分泌水平。结果脾脏淋巴细胞中CD4+CD25+Treg的百分比和Foxp3mRNA的表达在12h较3、6h明显升高(P<0.01);TNF-α、IL-10的分泌随时间点的延长均显著升高(P<0.01);随连翘剂量增加,TNF-α、IL-10分泌水平,Foxp3mRNA表达和CD4+CD25+Treg百分比均明显降低(P<0.05)。结论内毒素参与并诱导了CD4+CD25+Treg在淋巴细胞中的变化,其随内毒素作用时间延长呈上升趋势。连翘能显著降低CD4+CD25+Treg在淋巴细胞中的百分比。展开更多
