Background: This study aimed to explore the related metabolic biomarkers and to observe the effects of Yangxin Decoction (YXD) on plasma metabolism of patients with unstable angina (UA).
Methods: In total, 10 patients with UA (intervention group) and 10 healthy participants (control group) were recruited for this study from January 2009 to December 2010. Plasma samples from both groups were analyzed using liquid chromatography mass spectrometry (LC-MS). Principle component analysis (PCA) and partial least squares (PLS) were used to explore the correlations between metabolic markers in patients with UA.
Results: The LC-MS results indicated that the serum levels of 5 potential metabolic markers, namely, ceramide, glycocholic acid, allocholic acid, lithocholic acid, and leukotriene (LT) B4, were significantly higher in the intervention group than those in the control group.
Conclusion: The results of this study demonstrated potential metabolic markers that can be used to distinguish and diagnose patients with UA.

Bile salts are steroid biosurfactants that have a significant role in fat digestion, cholesterol micellar solubilization, and regulation of metabolism. They are important in pharmaceutical studies as modulators of the transport-permeability of drugs or as ligands for certain receptors. For the rational application of bile salts in medicine, it is necessary to have detailed knowledge of their aggregation capabilities (which determine their membranotoxicity and solubilization capacity). From the examination of bile salt derivatives, the in plane of lnk (RPHPLC) and micelle aggregation number n, as well as the anion of 7-oxodeoxycholic acid (7-OxD) and anion of cholic acid (C), are considered to be outliers, related to linear hydrophobic congeneric groups, which means that their micelles, in addition to being determined by hydrophobic interactions, are determined by hydrogen bonds, i.e., they form micelles with higher aggregation numbers than would be expected from the hydrophobicity of their steroid skeleton. For bile salts of the normal series in the formation of hydrogen bonds in secondary micelles, the crucial structural elements of the steroid skeleton are: α-equatorial-C3-OH group and α-axial-C12-OH group. Bile salts of the allo series, including allocholic (aC), allodeoxycholic (aDC) and allochenodeoxycholic acid (aCD), belong to the linear hydrophobic congeneric group. Their micelles are determined by hydrophobic interactions. It is assumed that for the analyzed allo derivatives, the A ring of the steroid skeleton is in the twisted boat conformation, which explains the spatial sheltering of their C3-OH group in micelles.

Adult sea lampreys locate spawning streams in the Great Lakes by using a migratory pheromone that is released by stream-resident larval conspecifics. Behavioral, electrophysiological, and biochemical analyses of larval release water have suggested that this pheromone is composed of several components, one of which is petromyzonol sulfate (PS), a known lamprey-specific bile acid. Its precursor, allocholic acid (ACA), has also been implicated. In this study, we employed high-performance liquid chromatography and mass spectrometry to look for both bile acids in various stream waters, thereby testing whether they might have a role in natural pheromone function. Although PS was measured at picomolar concentrations in streams known to contain larval lampreys and attract migratory adults, ACA was not. Neither compound was measured in streams lacking larvae. This finding indicates that PS is a component of the natural pheromone, and it suggests that ACA has little relevance.
