In order to understand the clinical characteristics of patients with coronary heart disease (CHD) in real world and provide reference for clinical prevention and treatment, this study analyzed informations of patient with CHD in hospital information system. Data from 17 national hospitals were collected. Select patients with coronaryheart disease in diagnosis of the first place in 17 hospitals, general informations and traditional Chinese medicine (TCM) syndrome, complications, medicine were analyzed using frequency method and association rules. This study included 84 697 patients with CHD, the majority of men and in the elderly. The average age of patients was 71 years. The proportion of men to women was about 1. 45: 1. Hospital stay time ranged from 8 to 14 d. The most common total hospitalization cost distribution was 5 000-20 000 RMB. Young patients have a rising trend year by year. The death of patients increased with increasing age. Common complications were hypertension, diabetes, cerebral infarction and hyperlipidemia, 57.24 percent of the CHD patient complicated with hypertension, 21.94 percent patients complicated with diabetes. Among TCM syndrome types, Qi-Yin deficiency and qi deficiency blood stasis were the most common syndromes. Blood stasis was the highest syndrome elements, accounted for 79.97%, followed by Qi deficiency, phlegm, Yin deficiency, and so on. The most common western medicine was aspirin, followed with isosorbide dinitrate, clopidogrel. The most common used traditional Chinese medicine was danhong injection, followed by shuxuetong injection. Combined with removing blood stasis drugs has been more common at present clinical treatment, there were 43.46 percent of patients combined with anti-platelet western drug and injection of removing blood stasis.

OBJECTIVEBased on real world research the circumstances of the clinical use of usual drugs combined with salvianolate injection are surveyed.

METHODDescriptive statistics on the use of salvianolate injection in 18 general hospitals in China.

RESULTIn 1 605 patients with coronary heart disease (CHD), salvianolate injection was most frequently (51%) combined with clopidogrel and isosorbide dinitrate. In addition this combination showed a higher clinical effectiveness as compared with other drug combinations.

CONCLUSIONIn the real world, salvianolate injection combined with usual treatment was found to be more effective than other treatment combinations. In addition practice conformed to the clinical treatment of coronary heart disease (CHD) guidelines for drug use. However, liver and kidney function, routine blood tests and the blood's coagulation function require ongoing monitoring.

The purpose of this study is to investigate the penetration effects and mechanism of N-arginine chitosan (ACS). This novel transdermal enhancer with a mimetic structure of cell-penetration peptides was synthesized by introducing hydrophilic arginine groups to the amino-group on chitosan's side chain. The structure of ACS was confirmed by FT-IR, 1H NMR and element analysis. In addition, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) was used to study the protein conformation and the water content of stratum corneum, and the result suggested that ACS can change the orderly arrangement of the molecules in the stratum corneum, making the stack structure of keratin become loose. And ACS can increase the water content of the stratum corneurn. Inverted fluorescence microscope and flow cytometry were used to examine penetration effect of ACS on Hacat cell. The result confirmed that the uptake of ACS was enhanced with increased substitution degree of arginine by 4-8 folds compared to chitosan. In vitro penetration studies on three electrical types of drugs were carried out using three model drugs of negatively charged aspirin, positively charged terazosin and neutral drug isosorbide mononitrate by the method of Franz diffusion cells. The results showed that ACS has obviously penetration of the negatively charged drug aspirin, and certain penetration of neutral drug issorbide mononitrate, but inhibition of positively charged terazosin. In vivo imaging technology research results show that the ACS can significantly enhance the fluorescence intensity of morin, which is the auto-fluorescence anionic drug. These obtained results suggested that ACS, as a promising transdermal enhancer, can change the structure of the keratinocytes and analog penetrating peptides promote absorption, but have certain selectivity for the drug.

Coronary artery spasm is an uncommon, but well recognized, etiology for acute myocardial infarction. However, cardiogenic shock with myocardial infarction resulting from simultaneous multiple coronary artery spasm has been rarely reported, and not in Korea. Recently, we experienced such a case in a 50-year-old Korean man without previous diagnosis of variant angina. The patient, hospitalized for blood sugar control, developed severe chest pain accompanying ST-segment elevation in multiple leads. The patient immediately received cardiac catheterization because of cardiogenic shock. Coronary angiogram revealed the severe and simultaneous spasm of three major epicardial arteries, which was promptly relieved by an intracoronary administration of isosorbide dinitrate. This case highlights the need to rule out the potential mechanism of coronary spasm even in the most severe episodes of acute coronary syndrome.

BACKGROUNDGlucocorticoid signaling exerts major roles in inflammation, metabolism and depression, which are three crucial factors accompanying or underlying coronary heart disease. Although accumulating evidence indicates the influence of glucocorticoids on the pathology and treatment of coronary heart disease, there is still a dearth of pharmaceutical mechanisms for this relationship. This study aimed to investigate the influence of drug treatment on glucocorticoid receptor levels in coronary heart disease.

METHODSEighty hospitalized patients (average age (59.0 +/- 7.5) years, 46 male and 34 female) with coronary heart disease were categorized into four groups with 20 members in each according to one of the four drugs they were treated with. The four drugs were: nitrated derivative isosorbide dinitrate, the beta-adrenergic receptor blocker metoprolol, the calcium antagonist nifedipine, and the HMG-CoA reductase inhibitor lovastatin. Glucocorticoid receptor protein levels of peripheral blood lymphocytes were tested using immunoblotting analysis before and after one month of treatment.

RESULTSImmunoblotting analysis showed increased glucocorticoid receptor levels after treatment with metoprolol and nifedipine. There were no statistically significant changes of glucocorticoid receptor levels after treatment with isosorbide dinitrate or lovastatin, although there were trends of up-regulation of glucocorticoid receptor expression after both treatments.

CONCLUSIONSBoth the beta-blocker and the calcium blocker can increase glucocorticoid receptor levels after chronic administration. This effect suggests a mechanism for their anti-inflammatory and other therapeutic roles for coronary heart disease and comorbid disorders.

The aim of present study is to investigate the cardioprotective effect of a new compound acetyl ferulaic isosorbide (AFI), composed of ferulaic acid (FA) and isosorbide mononitrate (ISMN) by esterification in myocardial ischemia/reperfusion (MI/R). Male Sprague-Dawley rats, subjected to 30 minutes of myocardial ischemia and 3 hours of reperfusion, randomly received one of the following treatments separately: SHAM, I/R (MI/R + solvent), SF (MI/R+SF, 40 mg x kg(-1), ig), ISMN (MI/R + ISMN, 30 mg x kg(-1), ig), SF + ISMN (MI/R + SF + ISMN, 40 mg x kg(-1) + 30 mg x kg(-1), ig) and AFI (MI/R + AFI, 10 mg x kg(-1), ig). Left ventricle developed pressures (LVDP) and the maximal first derivative of developed pressure ( +/-dP / dtmax) were monitored throughout the experiments. Myocardial infarction size, serum creatine kinase (CK) activity, lactate dehydrogenase (LDH) activity, superoxide dismutase (SOD) activity, hydrogen peroxide (H2O2), malondialdehyde (MDA) and nitric oxide (NO) production were determined at the end of reperfusion. Compared with SF, ISMN or SF + ISMN treatment groups, AFI treatment decreased infarction size (n=8, P < 0.01), improved cardiac function as evidenced by increased LVDP and +/- dP/dtmax (n=8, P < 0.05), increased serum SOD activity, reduced serum CK and LDH activities, H2O2 and MDA production (n=8, P < 0.05). The new compound AFI showed a stronger cardioprotective effect against MI/R injury than SF, ISMN or their combined administration did.

BACKGROUND: Multi-vessel off-pump coronary bypass surgery (OPCAB) imposes cumulative myocardial ischemia/reperfusion injury, which may be attenuated by continuous infusion of nitrate. However, nitrate infusion and consequent decrease in preload may be hazardous during heart displacement which causes restrictive filling of the ventricles. Therefore, we evaluated the effect of nitrate infusion on myocardial protection and hemodynamics in patients undergoing OPCAB, in a prospective, randomized and controlled trial. METHODS: Fifty patients with stable angina and left ventricular ejection fraction >40% undergoing elective, isolated, multivessel OPCAB were enrolled. Patients were randomized equally to either continuous infusion of isosorbide dinitrate 0.5microg/kg/min or same amount of normal saline during the surgery. Operative data including hemodynamic variables, intraoperative ST segment changes and postoperative cardiac enzyme release (creatine kinase-MB, troponin T) were compared. RESULTS: Patients characteristic and operative data including ST segment changes and use of vasopressors were similar between the groups except the total amount of infused crystalloid during the surgery which was significantly higher in the nitrate group. Postoperative variables including cardiac enzyme release were also similar between the groups. CONCLUSIONS: Prophylactic continuous infusion of nitrate during OPCAB exerted no additional benefit in terms of myocardial protection. It also, was not associated with accentuated decrease in cardiac output during heart displacement, and the decrease in preload seems to have been nullified by modest increase in fluid therapy.
