AIM:Atherosclerotic calcification is highly linked with plaque instability and cardiovascular events .Adenosine monophosphate-activated protein kinase ( AMPK) has been involved in the pathogenesis of various cardiovascular disease .The contributions of AMPKαsubunits to the development of atherosclerotic calcification in vivo remained unknown .We hypothesized that AMPKαsubunits may play a role in the development of atherosclerotic calcification .METHODS: Atherosclerotic calcification was generated by 24-week fed of western diet in ApoE-/-background mice .Calcification was evaluated in aortic roots and innominate arteries of ApoE-/-mice or in mice with dual deficiencies of ApoE and AMPKαsubunits globally ( AMPKα1 and AMPKα2 ) , or vascular smooth muscle cell ( VSMC)-specific or macrophage-specific knockout of AMPKα1 with atherosclerotic calcification pone diet . The mechanism of AMPKα1 in regulating Runx2 was further explored in human aortic VSMC .RESULTS: Ablation of AMPKα1 but not AMPKα2 in ApoE-/-background promoted atherosclerotic calcification with increased Runt -related transcription factor ( Runx2 ) expression in VSMC compared with ApoE-/-mice.Conversely, chronic administration of metformin, which activated AMPK, markedly reduced ath-erosclerotic calcification and Runx2 expression in ApoE-/-mice but had less effects in ApoE-/-/AMPKα1 -/-mice.Furthermore, VSMC-but not macrophage-specific deficiency of AMPKα1 in ApoE-/-background promoted atherosclerotic calcification in vivo com-pared with the controls .AMPKα1 silencing in human aortic VSMC prevented Runx 2 from proteasome degradation to trigger osteoblastic differentiation of VSMC .Conversely , activation of AMPK led to Runx 2 instability by inducing its small ubiquitin-like modifier modifi-cation (SUMOylation).Protein inhibitor of activated STAT-1 (PIAS1), the SUMO E3-ligase of Runx2, was directly phosphorylated by
AMPKα1 at serine 510, to enhance its SUMO E3-ligase activity.Ablation of PIAS1 serine 510 phosphorylation inhibited metformin-in-duced Runx2 SUMOylation, and subsequently prevented the effect of metformin on reducing oxLDL-triggered Runx2 expression in hu-man aortic VSMC.CONCLUSION:Deficiency of AMPKα1 in VSMC increases Runx2 expression and promotes atherosclerotic calcifi-cation in vivo.AMPKα1 phosphorylates PIAS1 to enhance Runx2 SUMOyalation and subsequent degradation .

OBJECTIVE:
To investigate the effect of calenduloside E on lipopolysaccharide (LPS)-induced inflammatory response in RAW264.7 cells and explore the underlying molecular mechanism.
METHODS:
CCK-8 assay was used to examine the effect of different concentrations of calenduloside E (0-30 μg/mL) on the viability of RAW264.7 cells. The release of the pro-inflammatory cytokines tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in RAW264.7 cells in response to pretreatment with 6, 8, and 10 μg/mL calenduloside E for 2 h followed by stimulation with 100 ng/mL LPS was detected using enzyme-linked immunosorbent assay (ELISA). The expression levels of iNOS and COX-2 and the activation of JAK-stats, MAPKs and NF-кB signaling pathways in the treated cells were determined using Western blotting. A reactive oxygen species (ROS) detection kit was used to detect ROS production in the cells, and the nuclear translocation of the transcription factor stat3 was observed by laser confocal microscopy.
RESULTS:
Calenduloside E below 20 μg/mL did not significantly affect the viability of RAW264.7 cells. Calenduloside E dose-dependently decreased the expression levels of iNOS and COX-2 induced by LPS, inhibited LPS-induced release of TNF-α and IL-1β, and suppressed LPS-induced JAK1-stat3 signaling pathway activation and stat3 nuclear translocation. Calenduloside E also significantly reduced ROS production induced by LPS in RAW264.7 cells.
CONCLUSIONS
Calenduloside E inhibits LPS-induced inflammatory response by blocking ROS-mediated activation of JAK1-stat3 signaling pathway in RAW264.7 cells.

Gastric cancer (GC) is a digestive tract tumor that occurs in the epithelial tissues of the gastric mucosa, seriously affecting the life and health of patients, and its mortality rate ranks the third among malignancies. Although medical technology has made great progress in recent years, the progression of GC still cannot be effectively controlled by surgery, chemotherapy, and targeted therapy. The pathogenesis of GC is extremely complex and is closely related to the tumor microenvironment, chronic inflammation, and immune escape, among which the reduction of tumor cell apoptosis is one of the important mechanisms for the occurrence and development of GC. Apoptosis refers to the process of spontaneous termination of cell life caused by genes under specific physiological or pathological conditions, which is of great significance for maintaining the stability of the internal environment. Researchers have found that in the GC state, mitochondrial endogenous apoptosis, endoplasmic reticulum stress, external death receptors, and other apoptosis pathways are regulated by multiple signaling pathways and genes, which together lead to the decline of GC cell apoptosis rate and thus promote the progression of GC. Chinese medicine is advantageous and characterized by multiple components, multiple targets, synergistic effect, and few adverse reactions. A large number of studies have shown that polysaccharide components, as effective components of Chinese medicine, have biological activities such as cancer inhibition, blood sugar control, anti-inflammation, antioxidant damage, and anti-virus, and can effectively inhibit the deterioration of GC by inducing cell apoptosis, gradually becoming a hot spot in GC drug research and development. However, systematic reviews on the apoptosis of GC induced by Chinese medicine polysaccharides are rarely reported. Therefore, this paper analyzed and summarized the studies of Chinese medicine polysaccharides in promoting apoptosis and interfering with GC, in order to provide a theoretical basis for the basic research, new drug development, and clinical application of Chinese medicine polysaccharides in the intervention of GC.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease with complex etiology. The pathogenesis of this disease, due to a combination of factors, is complex and has not yet been elucidated. Among them, intestinal mucosal barrier damage is the basic pathological change of UC. As a non-destructive response of cells, autophagy regulates intestinal mucosal immunity, inflammation, oxidative stress, and bacterial homeostasis through degradation and reabsorption to actively repair damaged intestinal mucosal barrier, exerting a key role in the occurrence and development of UC. The disease is mainly treated clinically with aminosalicylic acid preparations, glucocorticoids, and immunosuppressants. Western medicine treatment of the disease has a fast onset of effect, and the short-term efficacy is definite, but the long-term application is easy to be accompanied by more adverse reactions. Moreover, some drugs are expensive, bringing great physical and mental pain and economic burden to patients. Therefore, it is urgent to explore new therapies with stable efficacy and mild adverse effects. In recent years, a large number of studies have shown that Chinese medicine can regulate autophagy of the intestinal mucosa with multiple targets and effects and repair the intestinal mucosal barrier function, thereby inhibiting the development of UC. Many experiments have shown that the active ingredient or monomers and compound formulas of Chinese medicine can improve the immunity of the intestinal mucosa, inflammation, oxidative stress, and flora by regulating the level of autophagy to maintain the normal function of the intestinal mucosal barrier to effectively intervene in UC, providing a new measure for the prevention and treatment of UC. However, there is a lack of systematic review of Chinese medicine in regulating the level of autophagy in the intestinal mucosa for the prevention and treatment of UC. Therefore, based on the current research on UC, autophagy process, and Chinese medicine treatment, this article reviewed the relationship of autophagy and its key target proteins with UC to clarify the key role of autophagy in UC production and systematically summarized Chinese medicines targeting the regulation of autophagy to treat UC in recent years to provide new ideas for the treatment and drug development of UC.
