Ethnopharmacological Relevance: Taohong Siwu Decoction (THSWD) is a classic prescription of traditional Chinese medicine that is mainly used for promoting blood circulation and alleviating blood stasis. THSWD is composed of Prunus persica (L.) Batsch, Carthamus tinctorius L., Ligusticum chuanxiong hort, Angelica sinensis (Oliv.) Diels, Rehmannia glutinosa (Gaertn.) DC, and Paeoniae Radix Alba. This prescription eliminates blood stasis, supplements blood, and dredges the body as an auxiliary treatment.
Aim Of The Study: To investigate the mechanistic effects of THSWD in the treatment of cerebral ischemia.
Materials And Methods: we downloaded 39 blood components for THSWD from the PharmMapper database for target prediction studies and identified the targets of cerebral ischemia. We identified the intersection between the components and targets, constructed a protein-protein interaction (PPI) network, carried out GO and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. a rat model of cerebral ischemia was established in rats, and the results of network pharmacology were verified by in vivo experiments.
Results: Established a component-target-pathway network, further transcriptomics analysis identified a total of 11 target genes (Plau, Fabp4, Mmp9, Mmp12, Cfd, Lcn2, Trem1, Lgals3, Hmox1, Selp and Slc6a4), a total of seven pathways (focal adhesion, complement and coagulation cascades, Staphylococcus aureus infection, malaria, transcriptional dysregulation in cancer, progesterone-mediated oocyte maturation, and the PI3K-Akt signaling pathway), because both targets genes and the complement and coagulation cascade signaling pathways mediate inflammatory responses, the signaling pathways associated with the complement and coagulation cascades were selected for experimental verification. We detected inflammatory factors and several key proteins in the complement and coagulation cascade signaling pathway (C1qb, C1qc, C3ar1, C5ar1, and Cfd). Analysis showed that THSWD can reduce the release of inflammatory factors and inhibit activation of the complement signaling pathways, thereby protecting against ischemic stroke disease.
Conclusions: Our findings provide preliminary clarification of the predominant mechanism of action of THSWD when used to treat ischemic stroke.

Hereditary angioedema (HAE) is a rare,unpredictable,autosomal dominant disorder characterized by recurrent swelling in subcutaneous and submucosal tissue.In recent years,the pathophysiology and pathogenesis of HAE have been continuously studied and elucidated.In addition to the genes encoding complement 1 esterase inhibitors,new pathogenic variants have been identified in the genes encoding coagulation factor Ⅻ,plasminogen,angiopoietin-1,kininogen,heparan sulfate 3-O-sulfotransferase 6,and myoferlin in HAE.

Background: Cardiac AL and ATTR are potentially fatal cardiomyopathies. Current therapies do not address mechanisms of tissue dysfunction because these remain unknown. Our prior work focused on the amyloid plaque proteome, which may not capture tissue-wide proteomic alterations.

Background: High-density lipoprotein (HDL) modulates the blood-brain barrier and cerebrovascular integrity, likely influencing the risk of Alzheimer's disease (AD), neurodegeneration, and cognitive decline.
Objective: This study aims to identify HDL protein cargo associated with brain amyloid deposition and brain volume in regions vulnerable to AD pathology in older adults.
Methods: HDL was separated from the plasma of 65 non-demented participants of the Atherosclerosis Risk in Communities (ARIC) study using a fast protein liquid chromatography method.

Despite the unique properties of clay nanocomposites for cardiovascular applications, there are few data on the hemocompatibility of these nanomaterials. This study represents the first comprehensive investigation of the hemo/biocompatibility of clay nanocomposites . Nanocomposite coatings of polylactic acid (PLA)-polyethylene glycol (3 wt %)-Cloisite20A nanoclay (3 wt %) were produced using electrospraying technique as potential drug-eluting stent (DES) coatings.

Ticks have coevolved with their hosts over millions of years, developing the ability to evade hemostatic, inflammatory, and immunological responses. Salivary molecules from these vectors bind to cytokines, chemokines, antibodies, complement system proteins, vasodilators, and molecules involved in coagulation and platelet aggregation, among others, inhibiting or blocking their activities. Initially studied to understand the complexities of tick-host interactions, these molecules have been more recently recognized for their potential clinical applications.
