The search, conducted from November/2022-October/2024 was performed on EBSCO, CABI, CNKI, Cochrane Library, DOAJ, PUBMED, SCOPUS, and WEB OF SCIENCE databases using Hypertension AND Olea europaea L. Eligible studies included those evaluating the effect of Olea europaea L. on systolic/diastolic blood pressure in hypertensive or pre-hypertensive adults. Exclusion criteria were multi-preparation interventions. Data on reference, country, sample, intervention/control details, duration, and differences in systolic and diastolic blood pressure, adverse effects, and medication use were extracted manually. The mean differences, heterogeneity (I<sup>2</sup>) and quality of the studies were assessed using Review Manager (version 5.4).

The main etiology of CU is a type I allergic reaction mediated by immunoglobulin (Ig)E. This study mainly explored the therapeutic effect of quercetin in ovalbumin (OVA)-induced CU mice and investigated its target and mechanism in vitro. The CU symptom-alleviating effect of quercetin was assessed by the CU model. The possible molecular mechanisms of quercetin were initially inferred through bioinformatic and multi-database analyses. Quercetin targets were examined using mast cell activation experiments with CD300f knockdown. RT-PCR and western blot experiments were performed to verify the molecular mechanisms of quercetin. Quercetin relieved wheal and scratching times on the back skin of mice as well as reduced eosinophilic infiltration and mast cell degranulation in the skin lesions and inhibited the release of IgE, histamine, TNF-α, MCP-1, and IL-13 in the serum of mice. In addition, it exhibited potential therapeutic effects on CU through the PI3K-Akt signaling pathway. Meanwhile, quercetin upregulated CD300f in the skin of CU, activated CD300f, and induced downstream SHP-1 phosphorylation. Of note, quercetin bound to CD300f to prevent IgE-mediated LAD2 cell β-hexosaminidase release, histamine release, Ca<sup>2+</sup> influx, mast cell degranulation, and F-actin cytoskeleton remodeling by inhibiting the AKT/IKK/NF-κB inflammatory pathway.

This study investigates the therapeutic potential of Portulaca oleracea L. (POL) extract and its active constituent Oleracein E (OE) in attenuating Ang II-induced pathological cardiac remodeling and subsequent heart failure progression. An experimental model of hypertensive heart failure was established in C57BL/6 mice through continuous subcutaneous infusion of Ang II for 4 weeks, with Oleracein E (OE) intervention administered during the final 2 weeks of the protocol. To elucidate the molecular mechanisms underlying OE's cardioprotective effects, we employed an integrated approach combining RNA sequencing analysis, molecular docking simulations, and target validation through drug affinity response target stability (DARTS) and cellular thermal shift assay (CETSA) techniques. The experimental results demonstrated that both POL extract and its active component OE exerted significant cardioprotective effects against Ang II-induced cardiac dysfunction in murine models, primarily through attenuation of pathological cardiac hypertrophy and suppression of inflammatory responses. Transcriptomic profiling via RNA sequencing identified the MAPK signaling pathway as a critical mediator of these protective effects. Subsequent transcription factor analysis revealed STAT2 as a key regulatory component in this pathway. Importantly, OE treatment effectively mitigated inflammatory responses in both in vivo cardiac tissues and in vitro cultured cardiomyocytes by specifically inhibiting the Ang II-activated MAPKs/STAT2 signaling cascade. Genetic ablation experiments further confirmed the essential role of this pathway, as the anti-inflammatory efficacy of OE was completely abolished in cardiomyocytes with MAPKs or STAT2 deficiency. Molecular interaction studies employing in silico docking simulations combined with experimental validation through DARTS and CETSA techniques provided direct evidence of physical binding between OE and the STAT2 protein. Our findings demonstrate that Oleracein E (OE) confers cardioprotection against Ang II-induced myocardial injury through a novel mechanism involving STAT2 targeting and subsequent suppression of MAPK signaling-mediated inflammatory cascades.

Fisetin, a flavonoid extracted from cotinus coggygria scop, has shown potential in alleviating aging by clearing SCs. This study investigated the unexplored mechanisms and efficacy of fisetin in alleviating T2DM-related aortic aging. The T2DM mouse model was induced using a high-fat diet and low-dose streptozotocin injection. Chronic fisetin treatment's protective effects against aortic aging were assessed via senescence-associated beta-galactosidase (SA-β-Gal) staining, histopathology, and vasomotor function. RNA-sequencing and western blotting identified relevant signaling pathways and protein expression. Fisetin's effects on SCs and senescence-associated secretory phenotype (SASP) factors were evaluated through cell viability, apoptosis, and co-culture assays. Docking simulations suggested fisetin as a potential Phosphoinositide 3-kinase (Pi3k) inhibitor. In vivo, chronic fisetin treatment reduced aortic SCs burden, alleviating T2DM-related and natural aortic aging. In vitro, fisetin selectively induced apoptosis of senescent endothelial cells via regulating the Pi3k-Protein Kinase B (Akt)-B-cell lymphoma (Bcl)-2/Bcl-xl pathway and suppressed SASP and its detrimental effects.

However, TCM also has its limitations.
