Abstract Objectives Increasing attention has been paid to a range of botanical food supplement that help to maintain vascular health. Multiple components in botanical foods are expected to be working in concert with various targets. In a previous our animal study, Phellinus baumii and Salvia miltiorrhiza Bunge (PS) ameliorated endothelial and vascular dysfunction in a platelet activation rat model. This study aimed to provide the components, target molecules, phenotypes, signaling pathways, and investigate the mechanism of PS on vascular health. Methods Network biology analysis was based on the data from two clinical trials. The first clinical trial was performed in healthy subjects using high-fat-induced vascular dysfunction model. The second clinical trial was performed in healthy smokers. Differential markers obtained from clinical data, Affymetrix microarray, metabolomics, together with ingredient of PS, were mapped onto the network platform termed the context-oriented directed associations. A network of “component-target-phenotype-pathway” was constructed. Results The resulting vascular health network demonstrates that the components of PS are linked various target molecules for adhesion molecule production, platelet activation, endothelial inflammation, vascular dilation, and mitochondrial metabolism and detoxification, implicated with various metabolic pathways. Conclusions Using network biology methods, this study revealed the components and their target molecules, phenotypes, signaling pathways and provided wider information to support the synergistic mechanisms of PS on vascular health.

Health-promoting effects of plant foods have been emphasized in the last few decades and ascribed to the bioactive phytochemicals present therein—in particular, phenylpropanoids. The latter have been investigated for a number of preclinical biological activities, including their antioxidant power. Due to the paucity of human studies, in this randomized intervention trial, we investigated whether the acute intake of pigmented rice could increase the plasma bioactive levels and antiradical power in twenty healthy subjects. A crossover randomized controlled clinical trial was conducted on 19 volunteers. Artemide and Venere black rice cultivars were tested, while brown rice Carnaroli was used as a control. Each patient received randomly one serving (100 g) of rice on three different experimental days, separated by a 7-day washout period. After baseline blood withdrawal, time-course changes of plasma polyphenols, flavonoids and radical-scavenging capacity were determined at 30, 60, 120 and 180 min post rice intake. Compared to Carnaroli rice, the two black rice cultivars significantly increased the plasma levels of polyphenols and flavonoids at 60 and 120 min and, correspondingly, the plasma antiradical power at 60 min after consumption. Pigmented rice consumption can contribute to diet-related health benefits in humans.

Context: Antagonism of protein kinase Cβ (PKCβ) restores endothelial function in experimental models of diabetes and prevents vascular dysfunction in response to hyperglycemia in healthy humans. Objective: We tested the hypothesis that PKCβ antagonism would improve vascular function in subjects with type 2 diabetes compared with healthy control subjects. Design: The effect of PKCβ was evaluated in a randomized, placebo-controlled, double-blinded crossover trial. Setting: The study was performed in the outpatient setting of a university medical center. Participants: Thirteen subjects with type 2 diabetes without evidence of cardiovascular disease and 15 healthy control subjects were recruited via newspaper advertisement. Intervention: Subjects underwent a randomized, double-blind, crossover, placebo-controlled trial of the selective PKCβ antagonist ruboxistaurin mesylate. Subjects received each treatment for 14 d. Main Outcome Measure: Endothelium-dependent and endothelium-independent vasodilation of forearm resistance vessels was measured with mercury-in-silastic, strain-gauge plethysmography during intraarterial administration of methacholine chloride and verapamil, respectively. Markers of inflammation, fibrinolysis, endothelial damage, and oxidative stress were measured after each treatment. Results: Endothelium-dependent vasodilation of forearm resistance vessels was attenuated in diabetic subjects when compared with healthy subjects (P = 0.001). Endothelium-independent vasodilation did not differ between groups (P value not significant). Ruboxistaurin did not significantly change endothelium-dependent or endothelium-independent vasodilation or blood-based markers of inflammation, fibrinolysis, endothelial damage, and oxidative stress in either diabetic or healthy subjects. Conclusion: Endothelial dysfunction of forearm resistance vessels was not improved by 2 wk of selective PKCβ inhibition in patients with diabetes. These results suggest that PKCβ does not contribute significantly to vascular dysfunction in otherwise healthy patients with type 2 diabetes.
