Gliomas are the mostly observed form of primary brain tumor, and glioblastoma multiforme (GBM) shows the highest incidence. The survival rate of GBM is fairly poor; thus, discovery of effective treatment options is required. Among several suggested targets for therapy, the Axl/IL-6/STAT3 signaling pathway has gained recent interest because of its important role within cancer microenvironment. ⋯ In addition, gene expression, protein expression, and half-life of synthesized Axl protein were all suppressed by quercetin. By applying shRNA for knockdown of Axl, we could confirm that the role of Axl was crucial in the apoptotic effect of quercetin on GBM cells. In conclusion, we suggest quercetin as a potential anticancer agent, which may improve cancer microenvironment of GBM via the Axl/IL-6/STAT3 pathway.

To investigate the therapeutic efficacy of Scutellarin (SCU) on neurite growth and neurological functional recovery in neonatal hypoxic-ischemic (HI) rats. Primary cortical neurons were cultured to detect the effect of SCU on cell viability of neurons under oxygen-glucose deprivation (OGD). Double immunofluorescence staining of Tuj1 and TUNEL then observed the neurite growth and cell apoptosis in vitro,and double immunofluorescence staining of NEUN and TUNEL was performed to examine the neuronal apoptosis and cell apoptosis in brain tissues after HI in vivo. ⋯ Meanwhile, 20 mg/kg SCU treatment improved neurological functions and decreased the expression of astrocytes and microglia in the cortex and hippocampus of HI rats. Additionally, SCU treatment depressed the elevated levels of autophagy-related proteins and the p75 neurotrophin receptor (p75NTR) in both cortex and hippocampus. This study demonstrated the potential therapeutic efficacy of SCU by enhancing neurogenesis and restoring long-term neurological dysfunctions, which might be associated with p75NTR depletion in HI rats.

Citri Reticulatae Pericarpium (CRP), also known as Chenpi in Chinese, is the dry mature peel of Citrus reticulata Blanco or its cultivated varieties. CRP as the health-care food and dietary supplement has been widely used in various diseases. However, the potential pharmacological mechanisms of CRP to predict and treat various diseases have not yet been fully elucidated. ⋯ The 121 targets are closely related to various diseases of the cardiovascular system, respiratory system, gastrointestinal system, etc. These targets are further mapped to compound-target, target-disease, and target-pathway networks to clarify the therapeutic mechanism of CRP at the system level. The current study sheds light on a promising way for promoting the discovery of new botanical drugs.

Effects of Berberine on Gut Microbiota in Patients with Mild Metabolic Disorders Induced by Olanzapine.
Secondary metabolic disturbances in patients with schizophrenia or bipolar disorder may be attributed to olanzapine. It is important to prevent mild metabolic disorders progressing to metabolic syndrome. This study aims to investigate the effects of berberine on intestinal flora in patients with mild metabolic disorders induced by olanzapine. ⋯ The abundance of firmicutes and coliform were significantly lower and the abundance of bacteroides significantly higher in patients who received berberine compared to placebo after 12 weeks of treatment ([Formula: see text]< 0.05). In patients who received berberine, the abundance of firmicutes was significantly decreased, and the abundance of bacteroides was significantly increased, and in patients who received placebo, the abundance of firmicutes was significantly increased post-treatment, compared to baseline (both [Formula: see text]< 0.05). In conclusions, berberine may regulate intestinal flora and metabolism in patients with schizophrenia or bipolar disorder and mild metabolic disturbances induced by olanzapine.

The incidence of diabetes worldwide continues to rise, placing a huge economic and medical burden on human society. More than 90% of diabetic cases are type 2 diabetes (T2D). At present, the pathogenesis of T2D is not yet fully understood. ⋯ Traditional Chinese Medicine (TCM) presents unique advantages in the treatment of T2D. Multiple metabolites and metabolic pathways have been identified in the treatment of TCM, providing valuable biomarkers and novel targets for drug therapy and pharmacological mechanism. Therefore, this paper reviews the modern achievements of metabolomics in T2D research and the progress of TCM management in recent years, in order to provide valuable information for related research.
