Abstract: Objective:To investigate the effect of heart-protecting musk pill (HMP) on cardiac dysfunction of ischemic heart disease. Methods:79 cases of ischemic heart disease were randomly divided into the contrast group (39 cases) and the HMP group (40 cases). The contrast group was treated by angiotensin-converting enzyme inhibitors, angiotensin II receptorantagonist and diuretics. The HMP group were treated by HMP on the base of normal therapy. Three index including EF, BNP and 6-MWT were observed before and after one treatment course of three months. Results:In the HMP group, EF was improved obviously. The distance of 6-MWT was extended and BNP reduced. The difference between the HMP group and the contrast group had significant meaning (P0.05). Conclusion:Heart-protecting musk pill is safe and effective to treat the cardiac dysfunction of ischemic heart disease.

Abstract: Shexiang Baoxin Pill (SBP), derived from the traditional Chinese medicine, has been broadly applied for the treatment of cardiovascular diseases including coronary heart disease, heart failure, and hypertension in East Asia for decades. Emerging pharmacological studies have revealed that SBP displays pleiotropic roles in protecting the cardiovascular system, as seen by the promotion of angiogenesis, amelioration of inflammation, improvement of endothelium dysfunction, mitigation of dyslipidemia, repression of vascular smooth muscle cell proliferation, and migration and restraint of cardiac remodeling. In terms of clinical practice, the clinical trials and meta-analyses have proved the efficacy and safety of SBP. In this review, we, for the first time, systematically summarize the cardioprotective effects and underlying mechanisms of SBP and provide novel insights into future research directions of SBP based on the experimental and clinical perspectives.

Abstract: Ethnopharmacological relevance To identify the biomarkers in early period of acute myocardial infarction (AMI) in rat serum and reveal the effective mechanism of a Traditional Chinese Medicine (TCM) named Shexiang Baoxin Pill (SBP). Material and method A metabolomic approach using reversed-phase liquid chromatography/quadrupole time-of-flight mass spectrometry (LC-Q-TOF-MS) was developed. Results Fourteen biomarkers in the early period of acute myocardial infarction (AMI) in rat serum were identified. These biomarkers include 5-methylcytosine, cystathionine ketimine, 2-oxoadipic acid, thymidine, epinephrine, homocystine, uric acid, 12(S)-hydroperoxyeicosatetraenoic acid (12s-HPETE), 11-dehydrocorticosterone, 12(S)-hydroxyeicosatetraenoic acid (12s-HETE), deoxycorticosterone, corticosterone, aldosterone and cortisol. Through pathway analysis of these biomarkers, inflammation, hypertrophy and oxidative injury were considered the most relevant pathological changes in early period of AMI. Conclusion Identification of AMI biomarkers not only supplied a systematic view of the progression of AMI in the early period but also provided the theoretical basis for the prevention or treatment of AMI. The results demonstrated that SBP pretreatment could offer protective effects for AMI through regulating the pathway of steroid hormone biosynthesis.

Abstract: A metabolomic approach has been developed for evaluating the therapeutic effects of the bioactive components and the synergistic efficacy of the Shexiang Baoxin Pill (SBP) on myocardial infarction (MI) in rats. The MI rats were administered the SBP, muscone, cinnamic acid, bufalin, ginsenoside Re, ginsenoside Rb1, cholic acid, borneol, and a combined version of these bioactive components (SFSBP). Liquid chromatography/quadrupole time-of-flight mass spectrometry (LC-Q-TOF/MS) was used to obtain the mass data from the rats' serum. The number of biomarkers that were reversed by SFSBP was greater than any of the monotherapy groups. The PLS-DA score plots demonstrated that the SFSBP group results were located closer to the sham group than any of the monotherapy groups and that the SBP group was located closer to the sham group than the SFSBP treatment group. The reversing results observed with SFSBP showed synergistic effects when compared with those of the individual bioactive components that were used as monotherapy. Meanwhile, the SBP displayed superior regulation efficacy to SFSBP in MI rats, indicating that there must be other active components in the SBP that were responsible for the treatment of MI that were not included in the SFSBP treatment.

Abstract: A liquid chromatography-electrospray ionization-tandem mass spectrometry method was described for the simultaneous determination of resibufogenin, bufalin, gamabufotalin, telibufagin, arenobufagin, cinobufagin and bufotalin in rat plasma. Plasma samples were pretreated by liquid-liquid extraction with ethyl acetate. Chromatographic separation was carried out on an ACQUITY HSS T3 column with gradient elution using mobile phase consisting of acetonitrile-0.1% formic acid in water at a flow rate of 0.3 mL/min. All analytes showed good linearity over a wide concentration range (r>0.99). The lower limit of quantification was in the range of 0.5-10 ng/mL for seven bufadienolides. The mean recovery of the analytes ranged from 94.36 to 104.18%. The intra- and inter-day precisions were in the range of 1.74-13.78% and the accuracies were between 89.37 and 101.38%. The validated method was successfully applied to a pharmacokinetic (PK) study of the seven bufadienolides in rat plasma after oral administration of Shexiang Baoxin Pill (SBP). The selected PK marker compounds with typical efficacy/toxicity may provide a practical solution for marker compound selection and dosage design for the therapeutic drug monitoring and PK study of SBP in its clinical applications.

Abstract: Pien Tze Huang (PZH) is a well-known Traditional Chinese Medicine (TCM), characterized by a multitude of pharmacological effects, such as hepatoprotection and inhibition of inflammation and cell proliferative conditions. Many of these effects have been validated at the cellular, molecular and physiological levels but, to date, most of these findings have not been comprehensively disclosed. This review aims to provide a critical summary of recent studies focusing on PZH and its multiple pharmacological effects. As a result, we further discuss some novel perspectives related to PZH’s mechanisms of action and a holistic view of its therapeutic activities. A systematic review was performed focusing on PZH studies originated from original scientific resources. The scientific literature retrieved for this work was obtained from International repositories including NCBI/PubMed, Web of Science, Science Direct and China National Knowledge Infrastructure (CNKI) databases. The major active componentes and their potential functions, including hepatoprotective and neuroprotective effects, as well as anti-cancer and anti-inflammatory activities, were summarized and categorized accordingly. As indicated, most of the pharmacological effects were validated in vitro and in vivo. The identification of complex bioactive components in PZH may provide the basis for further therapeutic initiatives. Here we have collectively discussed the recent evidences covering most, if not all, pharmacological effects driven by PZH. This review provides novel perspectives on understanding the modes of action and the holistic view of TCM. The rational development of future clinical trials will certainly provide evidence-based medical evidences that will also confirm the therapeutic advantages of PZH, based on the current information available.
