Objective To explore the clinical significance of immunocyte subsets before and after immunosuppressive therapy in the peripheral blood of patients with immune thrombocytopenic purpura (ITP).MethodsThe percentages of immunocyte subsets in the peripheral blood of 35 patients with ITP and 20 healthy controls were detected by flow cytometry,including CD3+,CD4+,CD8+,CD56+,CD19+ lymphocytes and CD4+/CD8+.Results The percentages of CD3+ T lymphocyte (61.58 ± 6.45 ) %,CD4+ T lymphocyte (28.38 ±4.89)% and the ratio of CD4+/CD8+ 0.99 0.22 in patients with ITP were lower than those in healthy controls[( 67.85 ± 4.68 ) %,( 38.00 ± 3.37 ) %,1.54 ± 0.13,all P < 0.05].After immunosuppressive therapy,the percentages of CD3+ T lymphocyte ( 69.41 ± 5.03 ) %,CD4+ T lymphocyte (38.17 ±3.18)% and the ratio of CD4+/CD8+ 1.60 ±0.15 recovered to control levels.The percentages of CD8+ T lymphocyte (29.20 ±4.50)% and CD19+B lymphocyte ( 17.74 ±4.14)% were higher than those in healthy controls[( 24.82 ± 2.93 ) % and ( 12.09 ± 3.51 ) %,all P < 0.05].After the immunosuppressive therapy,the percentages of CD8+ T lymphocyte ( 24.06 ± 3.02 ) % and CD19+ B lymphocyte ( 10.90 ± 3.55 ) %recovered to control levels.There were no significant difference of the percentage of CD56+ lymphocyte among ITP patients ( 15.80 ± 2.85 )%,ITP patients after immunosuppressive therapy ( 15.16 ± 2.77 )% and healthy controls ( 16.36 ± 2.75 ) %.ConclusionThe aberrant immunocyte subsets are involved in the pathogenesis of ITP,and detection of immunocyte subsets might be helpful for the diagnosis and determination of therapeutic outcome of ITP.

AIM: To study the effect of Qingqi Liangying Injection on febrile rats induced by zymonsa and on content of PGE_2 as well as cAMP in rat hypothalamus. METHODS: The rat febrific model induced by 10% zymonsa solution was used to observe QingqiLiangying Injection's effect on the rat temperature, and the radioimmunoassay(RIA) was used to determin the content of PGE_2 and cAMP in hypothalamus of rats. RESULTS: Qingqi Liangying Injection had an obvious antipyretic effect on febrile rats; Qingqi Liangying Injection could significantly reduce the content of PGE_2 and cAMP. CONCLUSION: Qingqi Liangying Injection can obviously reduce the rat body temperature and the content of PGE_2 and cAMP in hypothalamus of rats.
