According to TCM theory, SF can invigorate Qi in the liver and other visceral organs through the meridian system. Furthermore, the liver’s pivotal role in regulating the functions of various visceral organs helps explain how SF can promote holistic health benefits. The main active ingredient of SF, schisandrin B (Sch B), has been found to improve mitochondrial ATP production and enhance glutathione redox status in multiple organs. This could account for the overall protective effects of Sch B on organs. Due to its stronger impact on liver function, the positive influence of Sch B on different organs may be facilitated by signal molecules originating from the liver.展开更多

This may be because beneficial bacteria in the intestine metabolize polysaccharides produce short chain fatty acids such as lactic acid and acetic acid, which reduces the pH value in the intestine and inhibits the growth of enterococcus and Escherichia coli. In conclusion, SCFP can treat and protect intestinal diseases to a certain extent, which provides a favorable basis for the treatment of intestinal diseases.展开更多

Methods: Primary cortical neurons were isolated from embryonic(E17-18) cortices of Institute of Cancer Research(ICR) mouse fetuses. Primary microglia and astroglia were isolated from the frontal cortices of newborn ICR mouse. Different cells were cultured in specific culture medium. Cells were divided into 5 groups: control group, LPS group(treated with 1 μg/mL LPS only) and EFSC groups(treated with 1 μg/mL LPS and 100, 200 or 400 mg/mL EFSC, respectively). The effect of EFSC on cells viability was tested by methylthiazolyldiphenyltetrazolium bromide(MTT) colorimetric assay. EFSC-mediated inhibition of LPS-induced production of pro-inflammatory mediators, such as nitrite oxide(NO) and interleukin-6(IL-6) were quantified and neuron-protection effect against microglia-mediated inflammation injury was tested by hoechst 33258 apoptosis assay and crystal violet staining assay. The expression of pro-inflammatory marker proteins was evaluated by Western blot analysis or immunofluorescence. Results: EFSC(200 and 400 mg/mL) reduced NO, IL-6, inducible nitric oxide synthase(iN OS) and cyclooxygenase 2(COX-2) expression in LPS-induced BV-2 cel s(P<0.01 or P<0.05). EFSC(200 and 400 mg/mL) reduced the expression of NO in LPS-induced primary microglia and astroglia(P<0.01). In addition, EFSC al eviated cel apoptosis and inflammation injury in neurons exposed to microglia-conditioned medium(P<0.01). The mechanistic studies indicated EFSC could suppress nuclear factor(NF)-κB phosphorylation and its nuclear translocation(P<0.01). The anti-inflammatory effect of EFSC occurred through suppressed activation of mitogen-activated protein kinase(MAPK) pathway(P<0.01 or P<0.05). Conclusion: EFSC acted as an anti-inflammatory agent in LPS-induced glia cel s. These effects might be realized through blocking of NF-κB activity and inhibition of MAPK signaling pathways.展开更多
