Abstract:
Objective To detect the ratio of CD19+-CD25+ and CD19+-CD25-B lymphocytes and content of IgA,IgG,IgM and complement C3 in patients with acute cerebral infarction and study their clinical significance. Methods Disease were diagnosed according to the history and cranlal computer tomography or magnetic resonance imagine.Venous blood of 69 cases with acute cerebral infarction and 115 cases with cerebral hemorrhage, 41 cases in normal control group was extrdcted. The ratio of CDl9+-CD25+and CD19+-CD25-B lymphocytes was determined by flow cytometry and content of IgA,IgG,IgM and C3 was measured with scattering turbidimetry.Changes in humoral immunological function were compared among patients with different courses of disease, imaging scores and neurological function scores. Results Differences in CD19+-CD25+and CD19+-CD25-B lymphocytes, IgA, IgG,IgM and C3 were not significant at the acute stage between cerebral infarction and cerebral hemorrhage (P＞0.05,for all).The ratio of CD19+-CD25+B lymphocytes and content of IgG and C3 at the acute stage of cerebral infarction were all higher than that at the recovery stage and in the control group (P＜0.05, for all). There was no statistical signmcance in humoral immunological indices between that at the recovery stage of cerebral infarction and in the control group (P＞0.05, for all). The ratio of CD19+-CD25+ and CD19+-CD25-B lymphocytes was significantly different among patients with different imaging scores (P＜0.05,for all).Neurological function scores at the acute stage of cerebrdl inflarction were not correlated with humoral immunological indices(P＞0.05,for all). Conclusions Same changes occur to humoral immunological function in patients with cerebral infarction and cerebral hemomlage, which might be related with stress,and location and scope of lesions.The larger the lesion of cerebral infarction is,the more obvious changes of humoral immunological function become; with the disappearing of stress,humoral immunological function gradually recovers.
