The results showed that RGH patients at acute period had a lower percentage of Tcl subsets in peripheral blood than that of healthy controls （P〈0. 001）, especially a remarkable decreased percentage of Tc1 subsets （P〈0. 001） among those RGH patients with recurrent number more than 3 in the recent half a year. Tc1/Tc2 ratio in the RGH patients at acute period was significantly decreased as conapared with normal control group （P〈0.05）. The recurrent number of acute patients in the recent half a year was significantly correlated with the percentage of Tc1 subsets and the ratio of Tc1/Tc2 （P〈 0.05）. A decreased percentage of Tc1 subsets was found among the RGH patients with recurrent number more than 3 in the recent half a year at recovery period in comparison with healthy volunteers （P〈0.05）, and it was significantly correlated with the recurrent number in the recent half a year （P〈0.05）. It is concluded that there are Tc1/Tc2 imbalance and a low level of Tc1 subsets in RGH patients who are relapsing repeatedly in the near period. The low level of Tc1 subsets may be an important factor for the recurrence of RGH and the reactivation of latent herpesvirus infection.展开更多

Methods: A two-color immunofluorescent staining of cellsurface antigen and intracellular cytokines for flowcytometric analysis was used for CD_3, IL-2, IL-10, IL-12,IFN-γ and TNF-α in CD_3^+ T-lymphocytes in activatedperipheral blood mononuclear cells of patients with RGH. Results: Compared to controls, patients with RGHshowed fewer CD_3^+ T cells (P<0.05) and IL-2 producing andIFN-γ producing T cells (P<0.02 and P<0.001, respectively)after in vitro stimulation with PMA and ionomycin in thepresence of a protein transport inhibitor. More IL-10producing and IL-12 producing T cells were found inpatients with RGH (P<0.01). There was no significantdifference in the number of TNF-α producing cells betweenRGH patients and controls (P<0.05). Conclusion: RGH patients showed relatively more Th2cytokines. The imbalance between Th1 and Th2 cytokinesresults in inhibitory effects on a series of cell-immuneresponses, which may play an important role in thepathogenesis of RGH.展开更多
