The control group received prednisone combined with azathioprine for routine immunotherapy, and the observation group received Buyi prescription combined with prednisone and azathioprine therapy. 12 weeks after treatment, the serum was collected to determine the levels of liver damage marker molecules, liver fibrosis marker molecules and T cell-related cytokines, and the peripheral blood was collected to determine the PD-1 and PD-L1 expression in CD4+T cells. Results:12 weeks after treatment, fluorescence intensity of CD4+PD-1+ and CD4+PD-L1+T cells in the peripheral blood of the observation group were significantly lower than those of the control group;serum ALT,γ-GT, PC-III, C-IV, IFN-γ and IL-17 levels were significantly lower than those of the control group while IL-4 and IL-10 levels were significantly higher than those of the control group.Conclusion:Buyi prescription combined with immunotherapy can reduce the expression of PD-1/PD-L1, adjust the CD4+T cell function, reduce the liver damage, inhibit the liver fibrosis and treat AIH effectively.展开更多

Methods: A total of 78 patients with advanced non-small cell lung cancer who were diagnosed and treated in our hospital between August 2015 and January 2017 were reviewed and then divided into the routine group (n=41) who received chemoradiotherapy alone and the Yiqi Yangyin Prescription group (n=37) who received chemoradiotherapy combined with Yiqi Yangyin Prescription therapy. The differences in serum levels of tumor markers, Th1/Th2 cytokines and Th17/Treg cytokines were compared between the two groups before and after treatment. Results: After treatment, serum tumor markers CA15-3, Cyfra21-1, HSP90 and CEA levels of Yiqi Yangyin Prescription group were lower than those of routine group;serum Th1 cytokines IFN-γ and IL-2 levels were higher than those of routine group while Th2 cytokines IL-4 and IL-5 levels were lower than those of routine group;serum Th17 cytokines IL-17 and IL-23 as well as Treg cytokines IL-10 and TGF-β levels were lower than those of routine group. Conclusion: Routine chemoradiotherapy combined with Yiqi Yangyin Prescription therapy can effectively reduce the tumor load and optimize the anti-tumor immune function in patients with advanced non-small cell lung cancer.展开更多

Methods: Data obtained from the Finnish Diabetic Nephropathy Study were linked with the Drug Prescription Register (purchases of medications 1995-2009). Generalized linear mixed models under gamma distribution were used to evaluate the medication costs. Results: The total costs of medication decreased (Group 1 from€11,290 to €8760;Group 2 from €12,800 to €9790)during the follow-up (P< 0.0001). The sametrend was observed for immunosuppressive drugcosts (P< 0.0001). Although the cost profiles were similar for the groups (P= 0.9), the cost level in Group 2 was higher than in Group 1 (P< 0.0001). In Group 1 the most common immunosuppressive combination was cyclosporine, azathioprine and corticosteroid, while cyclosporine, mycophenolate mofetil (MMF) with/without corticosteroid was the most common in Group 2. The estimated average costs of cyclosporine in combination withMMFwere 84% (€4130) higher than with azathioprine. Conclusions: Since diabetes or other drugs had only marginal impact on the total costs, the decreasing trend wasmainly due to the costs of immunosuppressants.This finding is consistent with the recent guidelines which recommend reducing doses of immunosuppressants over time to minimize sideeffects.The cost levels differed depending on the combinations of immunosuppressive drugs in use. Those who had MMF in the regimen generated higher costs.展开更多
