The treatment of cardiovascular diseases and obesity, two diseases posing a major risk to human health, has been plagued by the scarcity of potent and effective medication with fewer side effects. To address this problem, numerous efforts, and some progress, have been made. Among possible treatments are some medicinal herbs; particularly promising is Alisma orientale (AO). ⋯ Results from the research currently available reveal that active constituents of AO, such as alisol B 23-acetate, alisol A 24-acetace, and alisol A, have been proven to be effective for treating cardiovascular diseases by modulating the lipid metabolism of macrophages, improving the biological behavior of vascular smooth muscle cells (VSMCs), and enhancing anti-inflammatory effects. Moreover, the active constituents of AO can also intervene in obesity by modulating abnormal glucose and lipid metabolism and fat decomposition of the body by activating the AMPK- and PPAR-related signaling pathways. In summation, based upon our research of available literature, this review reveals that AO and its active constituents have a great potential to be used as drugs for treating cardiovascular diseases and ameliorating obesity.

Ischemic stroke is a serious health hazard that lacks effective treatment strategies. This study aims to investigate baicalin's effect on tight junctions and immune cell infiltration after ischemic stroke injury. Rat brain microvascular endothelial cells (BMECs) were treated with OGD/R to establish an in vitro model. ⋯ Baicalin decreased the neurological function score, infarct volume, and brain water content, relieved brain morphological changes, and inhibited immune cell infiltration in vivo. In conclusion, baicalin could reduce BMECs apoptosis, protect tight junctions, and resist immune cell infiltration, thereby alleviating ischemic stroke. Our findings potentially provide a novel treatment strategy for ischemic stroke.

Pulmonary fibrosis (PF) is a progressive pulmonary disease with no effective treatment and high mortality. Resveratrol has shown promising benefits in the treatment of PF. However, the probable efficacy and underlying mechanism of resveratrol in PF treatment remain unclear. ⋯ The protein and mRNA expression levels of TGF-[Formula: see text], Smad, and p-ERK correlated positively with the lung index, while the protein and mRNA expression levels of ERK correlated negatively with the lung index. These results reveal that resveratrol may have therapeutic effects on PF by reducing collagen deposition, oxidation, and inflammation. The mechanism is associated with the regulation of the TGF-[Formula: see text]/Smad/ERK signaling pathway.

Prostate cancer (PCa) is the second most prevalent cancer in men worldwide. The majority of PCa incidences eventually progress to castration-resistant PCa (CRPC), thereby establishing an urgent need for new effective therapeutic strategies. This study aims to examine the effects of morusin, a prenylated flavonoid isolated from Morus alba L., on PCa progression and identify the regulatory mechanism of morusin. ⋯ Morusin also attenuated tumor growth in a xenograft murine model. The results of RNA-seq indicated that morusin regulated PCa cells through the Akt/mTOR signaling pathway, while our western blot results confirmed that morusin suppressed phosphorylation of AKT, mTOR, p70S6K, and downregulation of the expression of Raptor and Rictor in vitro and in vivo. These results suggest that morusin has antitumor activities on regulating PCa progression, including migration, invasion, and formation of metastasis, and might be a potential drug for CRPC treatment.

Breast cancer is one of the most common malignancies in women, and exhibits high metastasis, recurrence and fatality rates. Novel therapies for breast cancer are constantly emerging, such as targeted therapy, oncolytic virotherapy, and immunotherapy. Despite their potential, these new therapies are still in their infancy, and chemotherapy remains the standard treatment for breast cancer. ⋯ Additionally, senescence, autophagy, angiogenesis, and glycolysis mechanisms were observed to play a role in their antibreast cancer activity. Furthermore, multiple signaling pathways contributed to the antitumor effects of S. baicalensi, such as the NF-[Formula: see text]B, Wnt/[Formula: see text]-catenin, SATB1, Bcl2 family proteins, Caspase, PI3K/Akt, mTOR, ERK, p38-MAPK, TGF-[Formula: see text]/Smad, and Hippo/YAP pathways. This review provides valuable insights into the role of S. baicalensis as a breast cancer treatment and acts as a foundation for further investigations in this field.
