Zedoarondiol Inhibits Neovascularization in Atherosclerotic Plaques of ApoE Mice by Reducing Platelet Exosomes-Derived MiR-let-7a.

Objective: To investigate the effect of zedoarondiol on neovascularization of atherosclerotic (AS) plaque by exosomes experiment.

Methods: ApoE mice were fed with high-fat diet to establish AS model and treated with high- and low-dose (10, 5 mg/kg daily) of zedoarondiol, respectively. After 14 weeks, the expressions of anti-angiogenic protein thrombospondin 1 (THBS-1) and its receptor CD36 in plaques, as well as platelet activation rate and exosome-derived miR-let-7a were detected.

Zedoarondiol inhibits monocyte adhesion and expression of VCAM and ICAM in endothelial cells induced by oxidative stress.

Zedoarondiol, a newly discovered compound derived from the roots of zedoary turmeric, a traditional Chinese herb, has demonstrated potential in reducing inflammation of the vascular endothelium and safeguarding it from harm. Nonetheless, the precise mechanism underlying these effects remains to be elucidated. In this study, we established a model of HUVEC injury induced by hydrogen peroxide.

Myocardial bridging phenomenon is not invariable: A case report.

Background: Myocardial bridging is a common anatomical malformation, and the milking effect is a characteristic phenomenon of myocardial bridging in coronary angiography. Generally, the phenomenon is invariable. However, this article reports an inconceivably rare myocardial bridging phenomenon that breaks through our conventional views.

Relationship between two blood stasis syndromes and inflammatory factors in patients with acute coronary syndrome.

Objective: To investigate the relationship between inflammatory factors and two Chinese medicine (CM) syndrome types of qi stagnation and blood stasis (QSBS) and qi deficiency and blood stasis (QDBS) in patients with acute coronary syndrome (ACS).

Methods: Sixty subjects with ACS, whose pathogenesis changes belongs to qi disturbance blood stasis syndrome, were divided into 2 groups: 30 in the QSBS group and 30 in the QDBS group. The comparative analysis on them was carried out through comparing general information, coronary angiography and inflammatory factors including intracellular adhesion molecule-1 (ICAM-1), chitinase-3-like protein 1 (YKL-40) and lipoprotein-associated phospholipase A2 (Lp-PLA2).

[Advances in studies on pharmacological action of main chemical constituent of Curcuma Zedoary in preventing in-stent restenosis].

Traditional Chinese medicine Curcuma Zedoary ( E'Zhu) contains essential oil, curcuminoid and other effective constituents, with such pharmacological actions as anti-platelet aggregation, lowing blood lipid, anti-oxidation and anti-inflammation. In recent years, studies have showed that certain extracts and chemical components of E'Zhu could mitigate myocardial cell mitochondria injury and protect vascular endothelium by enhancing heme oxygenase-1 activity, inhibit nuclear factor NF-kappaB, target genes interleukin-associated kinase-1 (IRAK-1), tumor necrosis factor receptor-6 (TRAF-6) and vascular cell adhesion molecule-1 (VCAM-1), reduce inflammatory infiltration, and inhibit growth factor-induced smooth muscle cells (SMCs) proliferation and migration by impacting oxidation of cellular phosphatases. Due to its different functions in vascular endothelial cells and smooth muscle cells, E'Zhu has been applied in drug-eluting stents, with a potential effect in preventing in-stent restenosis and thrombogenesis.

[Association study between Chinese medicine blood stasis syndrome and TIMI risk stratification of patients with unstable angina pectoris].

Objective: To study the correlation between thrombolysis in myocardial infarction (TIMI) risk stratification and blood stasis syndrome (BSS) score in patients with unstable angina pectoris (UAP), and to analyze the relation of BBS degree and UAP clinical outcomes.

Methods: Collected were general data, demographic data, risk factors, Chinese medical symptoms and syndromes, coronary artery angiography results, relevant physical and chemical examinations from 114 UAP inpatients. Gensini score, TIMI risk score, and BSS score of these patients were calculated.

Long-term effect of stent coating with zedoary essential components on neointimal formation in the porcine coronary artery.

Objective: To examine the effect of the zedoary essential component-eluting stent (ZES) on a porcine coronary neointimal formation.

Methods: ZES, sirolimus-eluting stents (SES), and bare metal stents (BMS) were randomly implanted in three different major epicardial vessels in 36 balloon-injured pigs. Coronary angiography, optical coherence tomography, and histomorphological analysis were used to determine antihyperplasia effects.

[Exploration on current clinical management of cardiovascular diseases].

Dramatic advances in the treatment of cardiovascular disease were witnessed in recent years, however, there are still some problems needed to be explored. The related issues in terms of coronary heart disease, atrial fibrillation and chronic heart failure were discussed in this paper, and the latest progress of integrative medical treatment on them were reviewed as well.

[Randomized comparative study on the lipid lowering effects of Zhikang Granule and simvastatin].

Objective: To compare the lipid lowering effects of Zhikang Granule (ZKG) and simvastatin.

Methods: Forty-five out-patients with hyperlipemia who met the entry criteria were enrolled and randomized into two groups in the ratio of 2: 1, 30 patients in the ZKG group and 15 patients in the simvastatin group. The lipid lowering effects and safety of treatment during the 24-week therapeutic period, as well as the influence of treatment on plasma high sensitivity C reactive protein (hs-CRP) level in patients were observed.

Clinical outcomes and cost-utility after sirolimus-eluting versus bare metal stent implantation.

Background: Randomized studies have shown beneficial effects of drug-eluting stent (DES) in reducing the risk of repeated revascularization. Other studies have shown higher proportion of death, myocardial infarction (MI) and increased cost concerning DES. However the long term safety and effectiveness of DES have been questioned recently.

Antithrombotic and antiplatelet therapies in relation to risk stratification in patients with non-ST elevation acute coronary syndrome: insights from the Sino-Global Registry of Acute Coronary Events.

Background: Antithrombotic and antiplatelet therapies have been proposed to treat non-ST elevation acute coronary syndrome (NSTEACS), yet limited information is available about their applications from a multicenter "real-world" clinical procedure, especially in China. This study was undertaken to characterize the use of antithrombotic and antiplatelet agents in relation to the risk levels of the NSTEACS patients who were enrolled in Sino-Global Registry of Acute Coronary Events (GRACEs) registry study.

Methods: We analyzed the data from 618 Chinese NSTEACS patients stratified into low-(n = 151), intermediate-(n = 233), and high-risk groups (n = 234) based on GRACE risk scores.

Predictive factors of recurrent angina after acute coronary syndrome: the global registry acute coronary events from China (Sino-GRACE).

Background: Many patients with acute coronary syndrome (ACS) develop recurrent angina (RA) during hospitalization. The aim of this non-randomized, prospective study was to investigate the predictive factors of RA in unselected patients with ACS enrolled in the global registry acute coronary events (GRACE) during hospitalization in China.

Methods: Between March 2001 and October 2004, enrolled were 1433 patients with ACS, including ST segment elevation myocardial infarction (662, 46.

Are impaired endothelial progenitor cells involved in the processes of late in-stent thrombosis and re-endothelialization of drug-eluting stents?

Drug-eluting stent (DES) now is the default selection for most of the interventional cardiologists. However, its benefits compromised by the stent-related thrombosis events. Given the catastrophic consequences, it is important to investigate possible mechanisms of stent thrombosis.
