Alisma Shugan Decoction attenuates hepatic fibrosis and endoplasmic reticulum stress in mice with carbon tetrachloride-induced fibrosis.

Background: Over the years, Alisma Shugan Decoction (ASD), because of its potent anti-inflammation activity, has been used in traditional Chinese medicine (TCM) for treatment of many inflammation-associated disorders including those of the heart, blood vessel and brain. Methods: Herein, we examined the probable therapeutic effect of ASD in carbon tetrachloride (CCl4)-induced liver injury and fibrosis mice models. Results: Our results demonstrate that ASD dose-dependently reduced the fibrosis-related increased collagen deposition secondary to liver tissue exposure to CCl4. Data from our biochemical analyses showed significantly less liver damage biomarkers including ALT, AST and hydroxyproline in the ASD-treated samples, suggesting hepato-protective effect of ASD. Furthermore, we demonstrated that treatment with ASD significantly reversed CCl4-induced elevation of TNF-α, IL-6, IL-1ß and MP-1. Interestingly, NF-κB signalling, a principal regulator of inflammation was markedly suppressed by ASD treatment. In addition, treatment with ASD deregulated stress signalling pathways by suppressing the expression of markers of unfolded protein response, such as ATF6, IRE and GRP78. Conclusion: In conclusion, the present study provides preclinical evidence for the use of ASD as an efficacious therapeutic option in cases of chemical-induced liver damage and/or fibrosis. Further large-cohort validation of these findings is warranted.

[Effect of combination of Chinese and Western medicines on sinus rhythm maintenance in patients with auricular fibrillation after conversion].

OBJECTIVE: To investigate the curative effects of irbesartan, amiodarone and Wenxin Granule (WG), applied alone or in combination, on sinus rhythm maintenance in patients with auricular fibrillation (AF) after conversion. METHODS: Forty-one patients of persistent AF, after their fibrillation being converted, were divided into three groups randomly, and treated with amiodarone (group A, n=14), irbesartan and amiodarone (group B, n=15), and WG plus irbesartan and amiodarone (group C, n=12) respectively for 6 months. RESULTS: Compared with that before treatment, the inner diameter of atria sinistrum reduced in group B and C, and the reduction in the latter was superior to that in the former (P < 0.05); the diameter of left ventricle also reduced in group C (P < 0.05); and the maintenance rate of sinus rhythm was higher in group C than that in group A (P < 0.05). CONCLUSION: Combined therapy of Chinese and Western medicines shows synergistic effect of anti-arrhythmia.
