Danggui Sini decoction alleviates oxaliplatin-induced peripheral neuropathy by regulating gut microbiota and potentially relieving neuroinflammation related metabolic disorder.

Background: Danggui Sini decoction (DSD), a traditional Chinese medicine formula, has the function of nourishing blood, warming meridians, and unblocking collaterals. Our clinical and animal studies had shown that DSD can effectively protect against oxaliplatin (OXA)-induced peripheral neuropathy (OIPN), but the detailed mechanisms remain uncertain. Multiple studies have confirmed that gut microbiota plays a crucial role in the development of OIPN.

[Injury of human gastric epithelial GES-1 cells by MNNG and its effects on Wnt/β-catenin signaling pathway].

The aim of this study was to investigate the mechanisms of mono-functional alkylating agent MNNG to damage human gastric epithelial GES-1 cells and roles of Wnt/β-catenin signaling pathway in the process. The GES-1 cells were treated with MNNG (2 × 10 mol/L) for 24 h. The morphological changes of the GES-1 cells were observed under inverted microscope 2 d after treatment.
