Correlation studies of P-glycoprotein and lymphocyte subgroup in patients with immune thrombocytopenia / 国际检验医学杂志

ABSTRACT

Objective To discuss the correlation of P-glycoprotein(P-gp) and lymphocyte subgroup(CD4+,CD8+) in patients with immune thrombocytopenia.Methods A total of 20 patients with immune thrombocytopenia were selected from August 2015 to September 2016 in the Eighth Hospital Affiliated to Sun Yat-sen University.According to the platelet count,all patients were divided into mild group and severe group,20 cases of health persons were selected at the same period as the healthy group,flow cytometry technique was used to detect the plasma lymphocyte subsets(CD4+,CD8+) and P-gp level of all the objects.Pearson correlation analysis was used to analyze the relationship between plasma P-gp and plasma CD4+,CD8+,CD4+ / CD8+ level,analyzed all the objects plasma platelet count,P-gp and CD4+,CD8+,CD4+ / CD8+ levels.Results Plasma CD4+,CD8+,CD4+ / CD8+ and P-gp level of severe group were significant higher than those of mild group(t=3.587,2.957,2.315,2.646,P<0.05),plasma CD4+,CD8+,CD4+ / CD8+ and P-gp level of mild group patients were significant higher than those of healthy group(t=5.479,2.921,4.536,7.750,P<0.05).Pearson correlation analysis results showed that the plasma levels of P-gp and plasma CD4+,CD8+,CD4+ / CD8+ levels were positively correlated(r=0.683,0.617,0.548,P<0.05).Conclusion Plasma CD4+,CD8+,CD4+/CD8+and P-gp level is associated with immune thrombocytopenia patients condition,plasma levels of P-gp closely links with abnormal immune function in patients with hyperthyroidism,prompting detection the level of change could help doctors to assess patients medication curative effect.
