多器官功能不全综合征患者外周血单核细胞炎性细胞因子分泌水平的动态观察

为探讨多器官功能不全综合征（ｍｕｌｔｉｐｌｅｏｒｇａｎｄｙｓｆｕｎｃｔｉｏｎｓｙｎｄｒｏｍｅ，ＭＯＤＳ）或多脏器衰竭的发病机理，对６８例ＭＯＤＳ患者外周血单核细胞分泌肿瘤坏死因子（ＴＮＦ）、白细胞介素１（ＩＬ１）及白细胞介素６（ＩＬ６）水平进行了动态观察。采用不同细胞因子生长依赖细胞株生长指数（ＭＴＴ法）测定方法，检测ＭＯＤＳ患者发病时及治疗３、５、７、１０及１５天后外周血单核细胞分泌ＴＮＦ、ＩＬ１及ＩＬ６水平。结果：ＭＯＤＳ患者发病后外周血单核细胞分泌ＴＮＦ、ＩＬ１及ＩＬ６的水平显著升高（Ｐ＜０．０１），并随着病情的进展逐渐增加，经治疗后于第５天逐渐下降，至第１５天时降至接近发病初期水平。由此表明：ＭＯＤＳ发病与细胞因子参与的机体过度炎症反应及超强免疫反应过程密切相关，细胞因子的分泌水平可作为ＭＯＤＳ病情轻重的客观判定指标之一。

RESEARCH ON THE KINETIC EFFECT OF INFLAMMATORY CYTOKINES PRODUCTION IN THE MONOCYTES OF MULTIPLE SYSTEM ORGAN FAILURE PATIENTS

The synthesis and secretion of inflammatory cytokines in the monocytes of 68 cases of multiple system organ failure (MSOF) patients was investigated by the method of MTT stained in cytokines dependent defferential cell strain. The data showed that the serum levels of tumor necrosis factor, interleukine 1 and interleukine 6 were increased ( P <0.01) in the monocytes of MSOF patients. The synthesis and secretion of these inflammatory cytokines gradually increased in the monocytes after onset of MSOF. After 5 days of treatment with antibiotics and electrolytes intravenous infusion, the secretion of TNF, IL 1 and IL 6 were decreased respectively. These results suggested that the TNF, IL 1 and IL 6 are integrated into system inflammatory responese and caused the injury to the tissues and organs. The production levels of these cytokines can be regarded as the index of MSOF and its severity.
