Jiangzhi Granule attenuates non-alcoholic steatohepatitis by suppressing TNF/NFκB signaling pathway-a study based on network pharmacology.

Jiangzhi Granule is a commonly used traditional Chinese medicine for treating non-alcoholic fatty liver disease. However, its key ingredients and underlying mechanisms for attenuating nonalcoholic steatohepatitis (NASH) remain unclear. To address this issue, UPLC-TOF-MS based chemical profiling, network pharmacology and animal experimental validation were employed. First, a total of 56 main ingredients of Jiangzhi Granule and 38 ingredients in the blood and liver (after oral administration) were identified. Then, 170 potential targets of the absorbed ingredients and 50 targets of NASH were identified, and 10 overlapped genes were identified as candidate targets of Jiangzhi Granule for NASH treatment. A Jiangzhi Granule-ingredients-targets-disease network was constructed using Cytoscape software, which included eight main ingredients (such as emodin, resveratrol and quercetin) and 10 candidate targets (such as TNF, IL6 and CCL2). Functional enrichment indicated that the candidate targets were enriched in multiple pathways (such as the TNF signaling pathway). Furthermore, a NASH mice model was constructed and intervened with Jiangzhi Granule. The results revealed that Jiangzhi Granule could ameliorate NASH characteristics, such as histopathological changes and liver cholesterol level. Meanwhile, Jiangzhi Granule significantly decreased the mRNA and protein expression of TNFα in NASH mice liver, suppressed NFκB activation, and inhibited the expression of macrophage activation marker F4/80 and M1-type polarization marker CD11b/CD11c. ELISA assay indicated that Jiangzhi Granule reduced pro-inflammatory cytokines (including TNFα, IL-1ß and IL-6) in the liver. Collectively, our results suggested that Jiangzhi Granule could attenuate NASH by suppressing TNF/NFκB signaling mediated macrophage M1-type polarization.

Clinical Efficacy of Modified Yanghe Decoction in Ankylosing Spondylitis: A Randomized Controlled Trial.

BACKGROUND This study evaluated the effects of Modified Yanghe Decoction on pain, disease activity, and functional capacity, and its safety in subjects with ankylosing spondylitis (AS). MATERIAL AND METHODS A randomized, controlled study of subjects with AS was conducted over 8 weeks to compare the efficacy of the Modified Yanghe Decoction to celecoxib-sulfasalazine therapy. Subjects were evaluated at visit 1, and at weeks 4 and 8 of the trial. The Bath ankylosing spondylitis disease activity index (BASDAI), nocturnal back pain (NBP), total back pain (TBP), patient global disease activity (PGDA), the Bath ankylosing spondylitis functional index (BASFI), and the Bath ankylosing spondylitis metrology index (BASMI) were measured at each time point. Safety was monitored throughout the study through blood, urine, and stool samples, along with heart, liver, and kidney function tests. The ASAS 20 improvement criteria were used as efficacy criteria. RESULTS A total of 80 subjects were included. Both treatment groups were effective: 32 subjects (80%) in the Modified Yanghe Decoction group and 34 (85%) in celecoxib-sulfasalazine group met ASAS 20 improvement criteria; no statistically significant difference between groups was observed (P>0.05). Two subjects in the Modified Yanghe Decoction group reported mild diarrhea during the trial. In the celecoxib-sulfasalazine group, 8 subjects experienced upper-abdominal pain; in 3 subjects this was combined with lowered white blood cell count and in 1 subject it was combined with mild proteinuria. This represents a statistically significant difference in safety (P<0.05) between the 2 treatments. CONCLUSIONS This study demonstrates the efficacy and safety of the Modified Yanghe Decoction in AS treatment, especially for patients who have poor clinical responses, severe adverse reactions, or for patients unable to afford the standard clinical options.
