【摘要】 目的　探讨脑脊液和血清S 10 0b蛋白含量对Guillain Barre综合征 (GBS)患者施万细胞损伤的评估价值。方法　采用酶联免疫吸附试验双抗体夹心法对 5 0例GBS患者 (重型组 19例 ,轻型组 31例 )和 2 2名正常人的脑脊液和血清S 10 0b蛋白含量进行检测 ,同时行脑脊液细胞学检查。对GBS患者还进行了脑脊液和血清的动态检测。结果　 (1)两组GBS患者脑脊液S 10 0b蛋白含量均高于对照组 (均P <0 0 1) ,重型组与轻型组差异亦有显著意义 (P <0 0 1) ;血清S 10 0b蛋白含量重型组患者高于轻型组和对照组 (均P <0 0 5 ) ,轻型组与对照组差异无显著意义 (P >0 0 5 )。 (2 )重型组患者脑脊液单核细胞比例明显高于轻型组和对照组 (均P <0 0 1) ,轻型组与对照组间差异无显著意义(P >0 0 5 )。 (3)GBS患者脑脊液S 10 0b蛋白含量随脑脊液单核细胞比例增减及病情的轻重而发生相应的变化。结论　脑脊液和血清S 10 0b蛋白含量与GBS患者病情严重程度相关。更多还原

【Abstract】 Objective To investigate the concentration of S-100 protein presenting in cerebrospinal fluid (CSF) and blood serum in patients with Guillain-Barré syndrome (GBS), and discuss the value of assessment in measuring S-100 protein level to Schwann′s cell insult. Methods S-100 beta protein was measured dynamically by ELISA in CSF and blood serum from 50 patients with GBS and 22 referencesThe patients were divided into two categories by disease severity: the severe group and the mild groupMeanwhile, CSF cytology was also detected. Results (1) The level of CSF S-100 beta protein in both severe and mild groups were higher than that of the control group (P<0.01)The level of CSF S-100 beta protein in severe group was also higher than that of the mild group (P<0.01)The S-100 beta protein level in blood serum in severe group was higher than that of the mild and the control groups (P<0.05)Statistically, there was no difference between the mild and the control groups (P>0.05)(2) The percentage of CSF monocyte in severe group was higher than that of the mild and the control groups(P<0.01)There were no statistical differences between the mild and the control(P>0.05)(3) There was a dynamic change of CSF S-100 beta protein level in GBS patients correlated with the percentage of CSF monocyte and the severity of disease. Conclusions CSF and blood serum S-100 beta protein level in patients with GBS may be related to the severity of the disease.更多还原
