Colorectal cancer, characterized by its high incidence, concealed early symptoms, and poor prognosis at advanced stages, ranks as the third leading cause of cancer-related deaths worldwide. Astragalus membranaceus (AM) refers to the dried roots of Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao and Astragalus membranaceus (Fisch.) Bge. In the theory of Traditional Chinese Medicine (TCM), it is believed to have the functions of tonifying qi and lifting yang, as well as generating body fluids and nourishing blood. ⋯ Moreover, it offers a synergistic enhancement when used in combination with chemotherapy, radiotherapy, targeted therapy, or surgical treatment. AM also has great potential in treating colorectal cancer when combined with other herbs. This review summarizes the relevant research findings on the treatment of colorectal cancer with AM, as well as its main pharmacological effects and molecular mechanisms, aiming to provide guidance for the development of new drugs, and offer direction for the conduct of more related research and promoting the development and application of AM.

Epimedium has been widely used in traditional Chinese medicine for several thousands of years. This plant is known for tonifying kidney Yang, strengthening muscles and bones, and dispelling wind and dampness. It is worth noting that icaritin, a prenylated flavonoid isolated from Epimedium, has received increasing attention in recent years due to its wide range of pharmacological activities. ⋯ Icaritin was approved by the State Food and Drug Administration in January 2022 for the treatment of advanced HCC, and has various clinical drug prospects. Although it has some disadvantages, including poor solubility, and low bioavailability, icaritin is still a prospective candidate for the development of naturally derived drugs, especially in the treatment of tumors and inflammatory diseases. This review aims to update and deepen the understanding of icaritin, and provide a theoretical basis for its further study.

Ginkgolic acids (GAs) are distinctive secondary metabolites of Ginkgo biloba (G. biloba) primarily found in its leaves and seeds, with the highest concentration located in the exotesta. GAs are classified as long-chain phenolic compounds, and exhibit structural similarities to lignoceric acid. Their structural diversity arises from variations in the length of side chains and their number of double bonds, resulting in six distinct forms within G. biloba extracts (GBE). ⋯ Currently, there is no definitive evidence supporting the mutagenic toxicity of GAs. This review primarily synthesizes recent advancements in understanding the pharmacological and toxicological effects of GAs, along with their underlying mechanisms. It is anticipated that this review will stimulate scholarly discourse and elicit valuable insights.

The accumulation of aging cells significantly contributes to chronic inflammatory diseases such as atherosclerosis. Human carotid artery single-cell sequencing has shown that large numbers of aging foam cells are present in the plaques of human patients. Berberine (BBR) has been shown to inhibit cell senescence, however, the mechanisms involved in its treatment of atherosclerotic senescence have not yet been determined. ⋯ Additionally, the anti-aging impact of BBR on atherosclerosis was negated when macrophage-specific RXR[Formula: see text] was knocked down using lentivirus (pLVCD68-shRNA RXR[Formula: see text]) in ApoE[Formula: see text] mice. BBR activated PPAR[Formula: see text] through RXR[Formula: see text]-PPAR[Formula: see text] immune complex in macrophage-derived foam cells, increased NEDD4 transcriptional activity, promoted ubiquitination of GATA4-p62 complex, and inhibited SASP-related inflammation. These findings suggest the potential of BBR as a novel approach to addressing SASP-associated inflammation in atherosclerosis.

This study aimed to clarify the protective effect of Glycyrrhizic acid (GL) against Diosbulbin B (DB) - induced liver injury in mice and investigate its mechanisms of action. A liver injury DB was established in mice through the oral administration of DB for 15 days. At the same time, GL was administered to the mice for treatment. ⋯ Furthermore, analysis of 16S rDNA gene sequencing revealed that GL effectively restored the relative abundance of beneficial bacteria, reduced the relative abundance of harmful bacteria, and reinstated the structure of the intestinal flora. Additionally, correlation analyses between BA and intestinal flora indicated that Firmicutes, Bacteroidota, TDGA, DGA, UDGA, GDGA, THDGA, and HDGA could serve as major markers for DB-induced liver injury. In conclusion, GL significantly improved DB-induced liver injury by increasing the expression of Nrf2/FXR-BSEP/MRP2/P-gp/UGT1A1, promoting BA efflux, regulating intestinal flora, and alleviating inflammation and oxidative stress.
