参麦注射液对树突状细胞免疫活性的影响 总被引:2,自引:0,他引:2
目的 研究参麦注射液对树突状细胞(DC)免疫活性的影响,并初步探讨其作用机理.方法 从人外周血分离单核细胞,对照组用GM-CSF和IL-4诱导DC,参麦组另加参麦注射液,两组均自第5天起加TNFa促成熟,倒置显微镜观察细胞形态;收集培养10天的DC用流式细胞仪做表型检测;用MTT法检测DC诱导T细胞增殖的作用;用ELISA法测定DC上清中IL-12分泌量.结果 外周血单核细胞经细胞因子及参麦注射液干预诱导10天,表现出典型DC形态,对照组和参麦组DC形态无差异;两组DC的CDla、CD40、CD80等表面分子表达无显著差异;参麦组DC诱导T细胞增殖的能力增强;参麦组DC分泌IL-12的量高于对照组.结论 参麦注射液对DC表面分子的表达无明显影响,但可增加IL-12的表达,增强DC的免疫活性. 相似文献

We conducted a retrospective study of the accuracy of liver biopsies in 392 patients with liver lesions. Postbiopsy diagnosis was 297 cases of primary liver cancers, 79 cases of secondary malignant tumors, 2 cases of non-Hodgkin's lymphoma, 10 cases of focal nodular hyperplasia, 2 cases of chronic inflammation, 1 tuberculosis case and 1 schistosomiasis case. Biopsy provided histological diagnosis in 100% of cases, sensibility and specificity of Ultra-Cut biopsy was 98.95% and 100% for the diagnosis of malignancy respectively; positive predictive value, 100%; negative predictive value, 71.43%; and accuracy, 98.98%. We identified no major procedure related complications despite the presence of thrombocytopenia in 37.5% of cases. Pain was the only reported adverse effect of liver biopsy (10.97%), and 11 patients required analgesics. We concluded that Ultra-Cut liver biopsy was a safe and effective technique, and was invaluable in the investigation and management of patients with liver lesions. 相似文献

谈如何提高供电可靠性管理 总被引:15,自引:0,他引:15
加强供电可靠性管理是电力企业的中心工作任务,是企业自身发展的要求,直接反映基层管电组织的综合管理水平。是开拓电力市场,提高企业效益的需要;是深化企业优质服务,树立良好的企业形象的需要,对加强低压配电网的管理有积极的推动作用。然而,如何保障配电网络的供电可靠性,确保电网的安全运行和广大农民生命财产安全,让企业、人民真正用上“舒心电、放心电”,将成为供电企业研究的新课题。 相似文献
