Abstract:
Objective: To study the expression of interleukin-2(IL-2), soluble interleukin-2 receptor (sIL-2R), determine the alteration of erythrocytic immunity and T cell subgroup in the blood of outer circulation in patients with hypertensive cerebral hemorrhage so and to probe into the relationship between them, and to explore the clinical significance. Methods: Enzyme linked immnunosorbent assay (ELISA) was used to determine the content of IL-2 and sIL-2R. The immunoadsorption was employed to examine the erythrocytic immune activity and its regulating function. Streptavidin-peroxidase(S-P) was used to determine the cell number of CD3 (cluster of differentiation3), CD4 and CD8. Results: The content of IL-2 in the group with hypertensive cerebral hemorrhage was significantly lower than that in the control group (P<0.01), and the content of sIL-2R increased. Red blood cell C3b receptor (RBC. C 3bR) and RBC immune adherence enhancing factor (RFEB) dropped greatly (P<0.01), while RBC immune complex rosette (RBC. ICR) and RBC immune adherence inhibiting factor (RFIR) increased greatly. The cell number of CD3 and CD4 decreased (P<0.01) and there was no obvious change in CD8 (P<0.05). Conclusion: The decrease of immune function was observed in patients with hypertensive cerebral hemorrhage. The determination of the content of IL-2, sIL-2R, erythrocytic immunity and the activity of T subgroup has an important clinical significance in the occurrence, development, treatment, and prognosis of hypertensive cerebral hemorrhage.
