Effect of Chinese Herbal Medicines for Nourishing Yin,Supplementing Qi,and Activating Blood on Reproductive Endocrine Activity and Immune Functions in Patients with Primary Sjogren's Syndrome

ABSTRACT Objective： To investigate the effect of Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood on the reproductive endocrine-immune network and its mechanisms in patients with primary Sjogren＇s syndrome （pSS）. Methods： Seventy pSS patients were randomly assigned to two groups using a randomized digital table： the integrative therapy group （36 cases） and the control group （34 cases）. Thirty healthy subjects were taken as a normal group. The control group was treated with hydroxychloroquine sulfate tablets alone, and the integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets. The treatment course was 6 months for both groups. Before and after treatment, serum estradiol （E2）, testosterone （T）, luteinizing hormone （LH）, prolactin （PRL） by radioimmunoassay and immunoglobulin （IgG） by immunodiffusion, erythrocyte sedimentation rate （ESR） by Westergren, interferon-γ （IFN-γ） and interleukin-4 （IL-4） by enzyme linked immunosorbent assay were determined. Results： E2 and T levels in all patients were lower than those of normal subjects before treatment （P〈0.05） and were increased significantly after 6-month treatment （P〈0.05）. ESR, FSH, LH, IgG, IFN - γ, IL - 4 and ratios of E2/T, and IFN --γ/IL in the patients were higher than those of normal subjects before the treatments （P〈0.05）, and were reduced significantly after the treatments （P〈0.05）. The T and IFN -γ levels and E2/T ratio in the patients treated with integrative therapy were reduced significantly compared with the control group （P〈0.05）. However, the PRL levels before and after treatment were not significantly changed in the two groups （P〉0.05）. The ratios of E2/T and IFN -γ/IL-4, and levels of IgG and ESR were positively correlated before and after treatment （P〈0.05）. Conclusions： The ratios of E2/T and IFN - γ/ IL-4 might be used as indicators of pSS activity. Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with Western medicine could improve the therapeutic effect by regulating the reproductive endocrine-immune network in pSS patients.

Effect of Chinese Herbal Medicine for Nourishing Yin,Supplementing Qi,and Activating Blood on the Th1/Th2 Immune Balance in Peripheral Blood in Patients with Primary Sjogren's Syndrome

Objective： To observe the effect of Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood on the expression of interferen- γ （IFN-γ,）/interleukin-4 （IL-4） in peripheral blood and disease activity in primary Sjogren＇s syndrome （pSS） patients, and to study the relationship between the immune balance of Th1/Th2 and the disease activity. Methods： A total of 66 pSS patients were randomized with tossing coins method into two groups： the integrative therapy group （34 cases） and the control group （32 cases）; and 28 healthy subjects were taken as the normal group. The integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets and the control group was treated with hydroxychloroquine sulfate tablets. The treatment course was 3 months for both groups. The levels of serum immunoglobulin G （IgG）, erythrocyte sedimentation rate （ESR）, IFN-γand IL-4 in peripheral blood were measured before and after treatment. Results： Compared with the normal group, the levels of IgG, ESR, IFN- γ and IL-4 were significantly increased in pSS patients （P〈0.05）. Remarkably, after 3 months of treatment, these levels were dramatically decreased in both the integrative therapy group and the control group, although still higher than the normal group. The levels of IgG, ESR, IFN- and IL-4 in the integrative therapy group were lower than the control group and the same group before treatment （P〈0.05）. The ratio of IFN-γ/IL-4 also significantly decreased after treatment. Moreover, the level of IFN- γ, and the ratio of IFN- γ/IL-4 in the integrative theraphy group were significantly lower than the control group （P〈0.05）. For all patients the ratio of IFN-γ/IL-4 before and after treatment was positive correlated with the levels of IgG and ESR. Conclusion： Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood can alleviate the disease activity of pSS by regulating the immune balance of Th1/Th2.
