AIM: To investigate the effects of simvastation on homocysteine-induced endothelial dysfunction and inflammatory response and the underlying mechanisms of such effects. METHODS: MTT assay was used to detect cell viability, and DCFH-DA assay was used to examine the levels of reactive oxygen species (ROS). Furthermore, Western blotting was performed to detect protein expression and electrophoretic mobility shift assay (EMSA) was used to detect NF-?B DNA binding activity. RESULTS: Homocysteine (0.1-1 mmol/L) decreased the human umbilical vein endothelial cell (HUVEC) viability and increased the levels of ROS. Western blotting and ELISA showed that homocysteine significantly increased the expression of TNF-?, IL-6, MCP-1 and ICAM-1. However, pretreatment with simvastation (1-20 ?mol/L) reversed the decreased cell viability and markedly suppressed an increase in the ROS level and the expression of TNF-?, IL-6, MCP-1 and ICAM-1 induced by homocysteine. Homocysteine induced p38 phosphorylation and such phosphorylation was also inhibited by simvastation and antioxidant NAC. EMSA and Western blotting showed that homocysteine induced NF-?B activation due to the increased phosphorylation of the inhibitory protein (I?B?) as well as the degradation of I?B?, while simvastation pretreatment almost completely blocked the NF-?B activation as well as the phosphorylation and degradation of I?B?. CONCLUSION: Simvastation inhibits homocysteine-induced endothelial dysfunction and inflammatory response through interfering with ROS-p38-NF-?B pathway.

Objective:To explore therapeutic effects of sodium nitroprusside (SNP) combined verapamil on no-reflow during percutaneous coronary intervention (PCI).Methods: A total of 106 patients, who suffered from no-reflow during PCI in our department from Jan 2011 to Dec 2013, were selected.According to random number table method, patients were divided into SNP group (n=55, received SNP based on routine treatment) and combined treatment group (n=51, received verapamil based on SNP group).Cardiac troponin I (cTnI) level before and 16h~18h after PCI, cardiac function indexes after 12-month follow-up, incidence of major adverse cardiovascular events (MACE) were measured and compared between two groups.Results: Compared with before PCI, there were significant rise in cTnI level in both groups on 16~18h after PCI, P=0.001 both;compared with SNP group, there were significant reductions in cTnI level [(1.31±0.44)μg/L vs.(0.11±0.02)μg/L] and percentage of cTnI>0.10μg/L (94.5% vs.54.9%) in combined treatment group, P=0.001 both.Compared with SNP group after 12 months, there was significant rise in left ventricular ejection fraction [(62.29±3.06)% vs.(65.65±3.94)%], and significant reductions in left ventricular end-diastolic dimension[(50.24±3.73)mm vs.(47.60±4.72)mm] and left ventricular end-systolic dimension [(33.29±2.11)mm vs.(31.00±4.33)mm] in combined treatment group, P<0.05 all.There were no significant adverse reactions during hospitalization and follow-up in both groups.Conclusion: When no-reflow occurs during PCI, intracoronary injection of SNP combined verapamil can improve cardiac function, and its safety is good, which is worth extending.

Objective To compare the efficacy and safety of singular double antithrombotie therapy (DT) using warfarin plus clopidogrel and the combined antithrombotie therapy of 3-month triple antithrombotie therapy (TT) using warfarin, aspirinand clopidogrel and 9-month double antithrombotie therapy (DT) for the patients with atrial fibrillation undergoing PCI. Methods Ninety patients with atrial fibrillation undergoing PCI were randomly divided into two groups evenly: one group was treated with dual antithrombotic therapy group (DT) and the other group with the combined therapy, e. g. 3-month triple antithrombotie therapy (TT) and 9-month double antithrombotie therapy (DT + TT for short). All patients were followed-up by 12 months. The two groups were compared in terms of incidences of death , myocardial infarction , stroke , target-vessel revascularisation , stent thrombosis and bleeding adverse events. Results The incidences of myocardial infarction, stroke, target-vessel revascularisation , stent thrombosis and bleeding adverse events in the TT + DT group were all significantly lower than the DT group (P < 0.05). The follow-up on the safety indicated that the rate of bleeding in the TT +DT group was insignificantly higher than the DT group (P > 0.05). Conclusion There is no significant difference in safety between the two groups. However, the therapy of TT + DT is more effective.

OBJECTIVETo characterize unknown glycometabolic state in patients with essential hypertension (EHT) and normotensive patients and determine which EHT patients are candidates for oral glucose tolerance tests (OGTTs).

METHODSThis cross-sectional study consecutively recruited 895 EHT patients and 486 normotensive patients. The data including blood glucose, blood pressure, blood lipids, angiography profiles, and left ventricular parameters were collected.

RESULTSOGTTs performed in all patients revealed that the prevalence of abnormal glucose metabolism (AGM) was significantly higher in EHT patients than in normotensive patients at both baseline (P<0.001) and post-OGTT analysis (P<0.001). In total, 76.4% of the individuals with impaired glucose tolerance and 78.2% of individuals with newly diagnosed diabetes would have remained undetected if OGTTs had not been performed. Newly diagnosed AGM was significantly correlated with the presence and severity of coronary stenosis and left ventricular structure abnormalities and dysfunction. EHT patients with fasting glucose ≥5.6 mmol/L, hypertension duration exceeding 10 years, coronary artery disease, high-sensitivity C-reactive protein >3 mg/L, or high levels of apoB/apoA-1 ratio were at high risk of AGM.

CONCLUSIONSAGM is more common in patients with EHT than in normotensive patients, and OGTTs is a cost-effective strategy to detect AGM in EHT patients.

OBJECTIVETo assess the diagnostic value of cardiac magnetic resonance (CMR) in patients with acute viral myocarditis.

METHODSThirty patients with suspected acute viral myocarditis admitted in first people's hospital of Shunde from June 2011 to June 2013 were included in this prospective study. The diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of acute viral myocarditis were evaluated by clinical diagnosis. Diagnostic value among different scan methods and Lake Louise criteria were compared.

RESULTSAcute viral myocarditis was diagnosed in 63.33% (19/30) patients.Values for sensitivity, specificity, PPV, NPV, and diagnostic accuracy within the overall cohort were 57.89%, 72.73%, 78.57%, 50.00%, 63.33%, respectively by edema imaging (ER).Values for sensitivity, specificity, PPV, NPV, and diagnostic accuracy within the overall cohort were 78.95%, 63.64%, 78.95%, 63.64%, 73.33%, respectively using global relative enhancement (gRE).Values for sensitivity, specificity, PPV, NPV, and diagnostic accuracy within the overall cohort were 78.95%, 54.55%, 75.00%, 60.00%, 70.00%, respectively using late gadolinium enhancement (LGE) criteria.Values for sensitivity, specificity, PPV, NPV, and diagnostic accuracy within the overall cohort were 84.21%, 81.82%, 88.89%, 75.00%, 83.33% using Lake Louise criteria. The sensitivity, specificity, PPV, NPV, and diagnostic accuracy using Lake Louise criteria were significantly higher than using ER, gRE, LGE alone(all P < 0.05).Specificity was higher using ER than using gRE and LGE (both P < 0.05). The sensitivity, NPV, and diagnostic accuracy were significantly higher using gRE than using ER (all P < 0.05) and was similar as using LGE (all P > 0.05).

CONCLUSIONCardiac magnetic resonance is an excellent imaging modality for the diagnosis of acute viral myocarditis.
