Detailed Description

Objective: To evaluate the modulation of immunity-related gene expression for the Sjögren's syndrome under Chinese herbal medicine (SS-1) treatment.

Method:

The evidence of the regulation of oxidative-related cytokines and the antioxidant capacity could be provided from the previous randomized, double-blinded, placebo-controlled, cross-over design, two-center clinical trial for evaluating the effect of Chinese herbal medicine (SS-1) for the Sjögren's syndrome patients. However, the clinical trail could not find out the modulation of immunity-related gene expression for SS-1 treatment, and it did set up a healthy control group for SS-1 comparison. This study want to establish a healthy control group for evaluating the normal range of oxidative stress and cytokines, which this work could be used to compare with the 72 SS-1 subjects in previous study. And This study also want to analyze the 770 immunity-related gene expression for the Sjögren's syndrome under the SS-1 treatment: (1) The best 20 (at least) efficacy SJS subjects who were evaluated before and after SS-1 treatments. (2) The 10 (at least) healthy control subjects. The findings could provide the evidence on the modulation of immunity-related gene expression for clinical manifestation, oxidative stress and cytokine in Sjögren's syndrome patients.

Expected Results:

  1. Establish the normal range of oxidative stress and cytokines for healthy control group.
  2. To evaluate the regulatory effect on oxidative stress and cytokine secretion between SS-1 group and healthy control group.
  3. To evaluate the immunity-related gene expression for the Sjögren's syndrome under the SS-1 treatment.
  4. To evaluate the immunity-related gene expression among the best efficacy SJS subjects and healthy control subjects.
  5. To evaluate the immunity-related gene expression with the characteristic of TCM tongue diagnosis.
  6. To analyze the correlation among clinical manifestations, Sjögren's syndrome -related clinical questionnaires and immunity-related gene expression.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: SS-1
SS-1 is composed of the powder of Gan-Lu-Yin, Sang-Ju-Yin and Xuefu-Zhuyu-Decoction with the ratio of 2:1:1. Patients take 6 gram of experiment medicine three times per day.
The patients will be divided into two groups (A and B) at random and all of them keep the routine treatment in the rheumatology OPD. Group A patients will receive 12 weeks SS-1 treatment first, and then stop the SS-1 for 4 weeks for wash-out phase, and then receive 12 weeks placebo treatment. Group B patients receive 12 weeks placebo first, and then stop the placebo treatment for 4 weeks for wash-out phase, and then receive 12 weeks SS-1 treatment. SS-1 is composed of 3 traditional Chinese herbal formula: Gan-Lu-Yin, Sang-Ju-Yin and Xuefu-Zhuyu-Decoction with the ratio of 2:1:1. The placebo is composed with corn starch, pigment and minimal dose of 1% SS-1. Patients in both groups take 6 gram of SS-1/Placebo three times per day.
