ABSTRACT
Objecfive To study T cell subsets distribution in peripheral blood from patients with ankylosing spondylitis(AS)and the role of cell immunity in AS.Methods 30 patients with untreated active phase AS and 30 healthy volunteers were enrolled.The expression of CD4+ and CD8+ T cell subsets were evaluated by flow eytome try.The correlation among T cell subsets and Bath AS function index(BASFI).Bath AS measurement index(BASMI),course of disease,age,ESR,hyper-sensitive C-reactive protein (hs-CRP) were analyzed.Results The level of CD4+ T cell and CD4/CD8+ratio were significantly lower than that of healthy volunteers[(29.24±9.22)% vs.(40.09±6.86) %,(0.96±0.49 ) vs.(1.70±0.67 ),P ＜ 0.01 ],and CD8+ T cell were significantly higher than that of healthy volunteers [(32.91±6.86) % vs.(25.60± 5.97 ) %,P ＜ 0.01 ].The level of CD4+ T cell subsets in peripheral blood of AS patients was negatively correlated with BASMI (r =-0.479,P ＜ 0.01 ),and CD8+ T cell subsets were positively correlated with ESR,hs-CRP,BASFI and BASMI ( r = 0.373,0.430,0.462,0.530,P ＜0.05 ).The ratio of CD4+/CD8+ was negatively correlated with hs-CRP,BASFI and BASMI (r = -0.465,- 0.473,- 0.426,P ＜ 0.05 ).CD4+,CD8+,ratio of CD4/CD8 were not significantly correlated with age and course of disease in patients with AS.Conclusion T cell subsets are significantly abnormal in peripheral blood of patients with AS,and the imbalance degree of T cell is correlated with severity and activity of AS,suggesting that T cell subsets imbalance plays an important role in the pathologensis of AS.
ABSTRACT
[Objective] To investigate the therapeutic effect of Honghua injection plus prednisone and cyclophosphamine on refractory nephrotic syndrom.[Methods] 38 patients with refractory nephrotic syndrom were given intravenous Honghua and cyclophosphamine plus oral prednisone.Serum total cholesterol,triglyceride,liver and renal function,blood routine test,24h protennuria were observed.[Results] Total effective ratio was 92.1%.Cure ratio was 73.68%.Partly cure ratio was 18.42% and ineffective ratio was 7.89%.[Conclusions] Patients with refractory nephrotic syndrom were treated by Honghua injection plus prednisone and cyclophosphamine,which could reduce the application of prednisone,its side effects and enforce its therapeutic effect.What is more,this treatment could lessen therapeutic process,prevent relapse and recoil,protect effectively the retreat syndrom of prednisone as well.
ABSTRACT
To reveal the involvement of oxidative stress in hypertension and insulin resistance. Angiotensin Ⅱ was given to adrenomedullin-knockout mice for 4 weeks. 4-Hydroxy-TEMPOL, a superoxide scavenger mimetic was also employed. The results suggested that adrenomedullin may exert a protective effect against insulin resistance via its intrinsic antioxidant effect.
