Objective To study the possible mechanism of Bushenqiangdu recipe in treatment of ankylosing spondylitis(AS). Methods 30 out-patients were treated by Bushenqiangdu recipe for 6 months. The expression level of IL-18,IFN-?,IL-4 mRNA in outer-circumference blood of as patients and healthy volunteers were studied,as well as the change expression level of IL-18,IFN-?,IL-4 mRNA of as patients outer-circumference blood before and after treatment. Result The expression level of IL-18,IFN-?mRNA in AS patients PBMC group is higher prominently than control PBMC group(P

Objective To investigate the changes of silver-stainng protein of nuclear organizer regions(AgNORs)expression of T lymphocytes and helper T (Th) cell subsets in peripheral mononuclear cells (PBMC) from cancer patients and to analyze the relationship between them.Methods AgNORs expression in T cells activated by a multiple clonal activator was examined using a special image system. After activation of PBMC with ionomycin plus PMA for 5 h, both interferon-? (IFN ?) and interleukin-4 (IL-4)producing cell frequencies were detected by enzyme-linked immunospot assay (ELISPOT). The stimulated with ionomycin plus PMA for 24 h, the IFN ?-and IL-4-production were assayed by ELISA.Resuts AgNORs expression of activated T cells in PBMC from cancer patients (n=86) and healthy persons (n=44) was (4.90?1.20) I.S% and (7.82?1.28) I.S% respectively. Th2 frequency was significantly higher and the ratio of Th1 to Th2 frequency was more lower in cancer patient group. Moreover, the IFN ? and IL-4 production in cancer patient group were changed in the way similar to Th subset frequencies. In lung cancer patients the AgNORs expression, Th1 frequency, Th1/Th2 ratio and IFN ? production were significantly decreased in metastasis or in recurrence status,AgNORs expression in cancer patients correlated with their Th1 frequencies, Th1/Th2 ratio, IFN ? production levels and Karnofsky′s estimators.Conclusions In analyzed cancer patient cases, the expression of AgNORs and the function of Th1 cell were significantly decreased and correlated.
