To investigate the effects and mechanism of the active components of Red Paeonia and Rhizoma chuanxiong (Xiongshao Capsule, XSC) on angiogenesis in atherosclerosis plaque in rabbits.
Fifty New Zealand rabbits were randomly divided into the normal group, the model group, and the three medicated groups treated respectively with Simvastatin (2.5 mg/kg per day), low-dose (0.24 g/kg per day) and high-dose (0.48 g/kg per day) XSC, 10 in each group. Rabbits in the normal group were fed with regular diet. To those in the other four groups, high fat diet was given, and a balloon angioplasty was performed two weeks later to establish abdominal aortic atherosclerosis model. Then, the model rabbits were fed continuously with high fat diet, and to those in the medicated groups, the testing drugs were added in the forage correspondingly for 6 successive weeks. Levels of blood lipids were measured at the end of the experiment. Meantime, serum levels of high sensitivity C-reactive protein (hsCRP) and tumor necrosis factor alpha (TNF-alpha) were detected with enzyme-linked immunoassay; the plaque area (PA), cross-sectional vascular area (CVA) and correcting plaque area (PA/CVA) were determined quantitatively using imaging software; and the protein expression of vascular endothelial growth factor (VEGF) and factor VIII related antigen (FVIIIRAg) in plaque was detected using immunohistochemical method.
As compared with the model group, the content of total cholesterol (TC) in the three medicated groups, and contents of triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) in the Simvastatin group were lower to various extents (P<0.05, P<0.01). The serum level of hsCRP in all modeled rabbits was higher than that in the normal group, but in the three treated groups it was significantly lower than that in the model group (P<0.05, P<0.01). Expressions of VEGF and FVIIIRAg, as well as PA/CVA in the three medicated groups were significantly lower than those in the model control group (P<0.05, P<0.01).
The active components of Red Paeonia and Rhizoma chuanxiong have definite effects in delaying the genesis and development of atherosclerosis, its mechanism might be related with the inhibition on angiogenesis in plaque, and also with its actions of lipo-metabolism regulation and anti-inflammation.
"According to traditional Chinese medicinal theory, CR could promote blood and Qi circulation and dispel wind and relieve pain in TCM . For its reputation of facilitating blood circulation and dispersing blood stasis , CR is not only used for medicinal purpose, like treating atherosclerosis , ischemic stroke , vasodilation , and thrombus formation , but also for food preparation and health care products, such as mutton soup , tobacco flavor additive, and natural preservative .

[Show abstract][Hide abstract] ABSTRACT: Chronic headache such as migraine and nervous headache has become one of the most common locations of pain and one of the most difficult diseases to recover due to its numerous causes and inconvenience to keep acesodyne administration for a long time. However, there are a series of treatment theories and herbal formulas for this disease in traditional Chinese medicine (TCM), in which Da Chuanxiong formula (DCXF), a herb pair composed of Chuanxiong Rhizoma (CR), Chuanxiong in Chinese, and Gastrodiae Rhizoma (GR) called as Tianma in China, is a greatly classic representative. This formula has been used for headaches via dispelling wind pathogen and dissipating blood stasis for many years in TCM. In recent years, the efficiency and representativeness of DCXF have garnered many researchers' attention. To reveal the compatibility mechanism and develop innovative Chinese herb, herein ethnopharmacological relevance, chemical characters, and pharmacological actions of DCXF are detailed. It is expected to give a comprehensive interpretation of DCXF, namely, Chuanxiong Tianma herb pair (CTHP), to inherit the essence of herb pair and innovate drug delivery system of this prescription.

"The combination of Red Paeonia and RC shows a more evident effect on atherosclerosis (Xu et al., 2007). The active components of Red Paeonia and RC definitely delay the genesis and development of atherosclerosis (Zhang et al., 2009a), lower the serum levels of matrix metalloproteinase-3 (MMP-3) and MMP-9, suppress the expression of MMP-3 and cluster of differentiation antigen 40 ligand (CD40L) in plaque, and decrease the blood content of total cholesterol. These might be associated with the role of XC stabilizing the atherosclerotic plaque (Zhang et al., 2009b). "
[Show abstract][Hide abstract] ABSTRACT: Ligusticum chuanxiong Hort (LC; Umbelliferae) is an effective medical plant, which has been extensively applied for many years to treat various diseases with other Chinese herbal medicines. Although a considerable amount of scientific research was reported on LC in the last decade, it is currently scattered across various publications. The present review comprises the chemical and pharmacological research on LC in the last decade.
The objective of this review is to bring together most of the scientific research available on LC and evaluate its effects and mechanisms.
The information for 82 cases included in this review was compiled using major databases such as Medline, Elsevier, Springer, Pubmed, and Scholar.
The compounds contained in LC can be divided into five kinds, essential oil (EO), alkaloids, phenolic acids, phthalide lactones, and other constituents. A great deal of pharmacological research has been done, which mainly focuses on cardiovascular and cerebrovascular effects, antioxidation, neuroprotection, antifibrosis, antinociception, antiinflammation, and antineoplastic activity.
A large number of pharmacological and chemical studies during the last 10 years have demonstrated the vast medicinal potential of LC. It is still very clear that LC is a plant with widespread use now and also with extraordinary potential for the future. The documents strongly support the view that LC has beneficial therapeutic properties and indicates its potential as an effective adaptogenic herbal remedy.
[Show abstract][Hide abstract] ABSTRACT: Chuanxiong Rhizoma (Chuan-Xiong, CX), the dried rhizome of Ligusticum chuanxiong Hort. (Umbelliferae), is one of the most popular plant medicines in the World. Modern research indicates that organic acids, phthalides, alkaloids, polysaccharides, ceramides and cerebrosides are main components responsible for the bioactivities and properties of CX. Because of its complex constituents, multidisciplinary techniques are needed to validate the analytical methods that support CX's use worldwide. In the past two decades, rapid development of technology has advanced many aspects of CX research. The aim of this review is to illustrate the recent advances in the chemical analysis and biological activities of CX, and to highlight new applications and challenges. Emphasis is placed on recent trends and emerging techniques.
