title: [Effects of qingyang toujie mixture in combination with prednisone tablet on Th1/Th2 cytokines in patients suffering from systemic lupus erythematosus].
abstract: OBJECTIVE
  To research the effects of Qingyang Toujie Mixture (QTM) in combination with prednisone tablet on the balance of Th1 and Th2 (Th1/Th2) of systemic lupus erythematosus (SLE) patients of yin deficiency syndrome (YDS).
  
  
  METHODS
  Totally 42 patients with SLE were recruited from clinics of internal medicine and hospitalization department of First Hospital Affiliated to Guangzhou University of Traditional Chinese Medicine from August 2009 to March 2011. They were randomly assigned to the treatment group (22 cases) and the control group (20 cases) according to the random digit table. Another 12 healthy subjects were recruited as the healthy control group from employees of First Hospital Affiliated to Guangzhou University of Traditional Chinese Medicine and healthy students in physical examinations. All patients took prednisone tablet. The dosage was adjusted according to the severity of SLE activity index and the condition: 40 -60 mg per day for severe active stage; 20-40 mg per day for moderate active stage; 15 -20 mg per day for light active stage; and less than 15 mg per day for those in the stable stage, respectively. When patients' condition had been stabilized for 1 to 2 weeks, the dosage was gradually reduced according to the method of hormone reduction. In case of the recurrence of symptoms or when complicated with lupus nephritis or lupus encephalitis uncontrollable, standard shock therapy with Cyclophosphamide Injection (0.5-1 g/m2 body surface area, intravenous dripping, once every 4 weeks) was performed. Patients in the treatment group took QTM additionally, one dose daily, taken in two portions, once in the morning and once in the evening. Those in the control group took placebos additionally, one dose daily, taken in two portions, once in the morning and once in the evening. The therapeutic course was 6 months for all. No measure was taken for those in the healthy control group. Venous blood was withdrawal before and after treatment. Th1 cytokines (IFN-gamma, IL-12) and Th2 cytokines (IL-10, IL-4) were detected by ELISA.
  
  
  RESULTS
  Compared with the healthy control group, the serum Th1 cytokines such as IL-12 and IFN-gamma, Th2 cytokines such as IL-10 and IL-4 increased, the Th1/Th2 ratios such as IFN-gamma/IL-4 and IL-12/IL-10 decreased in the treatment group and the control group before treatment (P < 0.01). Compared with before treatment in the same group, the serum Th1 cytokines such as IL-12 and IFN-gamma decreased, the serum Th2 cytokines such as IL-10 and IL-4 decreased, the ratios of Th1/Th2 cytokines such as IFN-gamma/IL-4 and IL-12/IL-10 increased in the treatment group (all P < 0.05). Compared with the control group after treatment, IL-4 decreased, and the ratio of IFN-gamma/IL-4 increased in the treatment group (P < 0.05). Fewer patients suffered from adverse reactions in the treatment group than in the control group (P < 0.01).
  
  
  CONCLUSIONS
  QTM in combination with prednisone tablet was effective to improve the balance of Th1/Th2 cytokines, and alleviate the toxic and adverse reactions of hormone or immune inhibitors.
