3A prospective randomized antiplatelet trial of cilostazol versus clopidogrel in patients with bare metal stent显示文摘Background Cilostazol is a newly developed antiplatelet drug that has been widely applied for clinical use. Its antiplatelet action appears to be mainly related to inhibition of intracellular phosphodiesterase activity. Recently, cilostazol has been used for antiplatelet therapy after coronary bare metal stent implantation for thrombosis and restenosis prevention. This prospective randomized and double blind trial was designed to investigate the safety and efficacy of cilostazol for the prevention of late restenosis and acute or subacute stent thrombosis. Methods One hundred and twenty patients who underwent elective stent were randomly assigned to treatment group with cilostazol 200 mg/d (n = 60), clopidogrel 75 mg/d and aspirin 100 mg/d or to control group with clopidogrel treatment 75 mg/d (n = 60) and aspirin 100 mg/d. Follow-up coronary angiography was performed 6-9 months later. Results Nine months major adverse cardio-cerebral event (MACCE) were lower in treatment groups (P<0.05). The quantitative coronary angiography (QCA) at 6 months follow-up showed that minimum lumen diameter (MLD) was higher in treatment group than that of control group [(2.14±0.52)mm vs (1.82±0.36)mm, P<0.05]. Late lumen loss (LL) [(0.82±0.42)mm vs (1.31±0.58)mm; P<0.01], restenosis rate (RR) (14% vs 32%; P<0.05) and target lesion revascularizaion (TLR) rate (5% vs 17%; P<0.05) were lower in treatment group than in control group. Conclusion Cilostazol therapy is an effective regimen for prevention not only stent thrombosis but also RR and TLR through reducing MLD without the risk of increasing bleeding.CHEN Yun-dai, LU Yan-ling, JIN Ze-ning, YUAN Fei and Lü Shu-zhengDepartment of Cardiology, Beijing Anzhen Hospital, Capital University of Medical Sciences Beijing Institute of Heart, Lung and Blood Vessel, Beijing 100029, China 2006Chinese Medical Journal2006,,5:15

5Comparative study of on-pump and off-pump coronary bypass surgery for patients with triple coronary artery disease显示文摘Objective To compare the clinical results of on-pump and off-pump coronary bypass surgery in patients with triple-vessel disease. Methods A total of 300 consecutive isolated multiple CABG patients entered into off-pump coronary artery bypass (OPCAB group, n=150) or CABG with cardiopulmonary bypass (CPB) (CCABG group, n=150). There were no significant difference regarding the degree of angina, history of myocardial infarction, diabetes and left main disease between two groups. The ejection fraction in OPCAB before surgery was lower than CCABG (P<0.01). More patients had a history of stroke, and abnormal renal function in OPCAB pre-operatively( P< 0.01 ). Single deep pericardial stay suture with a sling snared down was used to expose the target vessels in OPCAB, along with a stabilizer and a coronary shunt. Medi-Stim Butterfly Flowmeter was used to measure the flow of grafts in both groups. Results No one in OPCAB needed to convert to CCABG. The number of the distal anastomosis and the index of completeness of revisualization (ICR) were similar in both groups. The respiratory support time, the volume of chest tube drainage and blood transfusion were less in OPCAB than in CCABG post-operatively (both P<0.01). The incidence of pulmonary dysfunction and renal insufficiency were less in OPCAB than in CCABG post-operatively ( both P<0.05 ) . There was no significant difference in the mortality and other morbidities (peri-opetative MI, stroke, atrial fibrillation). Conclusion OPCAB can be applied to patients with triple vessels disease and achieved similar completeness of revascularization, similar early surgical results with shorter respiratory support, reduced transfusion requirement, less pulmonary dysfunction and abnormal renal function.CHEN Xin, XU Ming, SHI Hong-wei, MU Xin-wei, CHEN Zhen-qiang, QIU Zhi-bing Nanjing First Hospital Affiliated to Nanjing Medical University, Nanjing Heart Institute, Nanjing, 210006 P.R.China 2004介入放射学杂志2004,13,S2:7
6MicroRNA: A matter of life or death显示文摘Progressive cell loss due to apoptosis is a pathological hallmark implicated in a wide spectrum of degenerative diseases such as heart disease, atherosclerotic arteries and hypertensive vessels, Alzheimer's disease and other neurodegenerative disorders. Tremendous efforts have been made to improve our understanding of the molecular mechanisms and signaling pathways involved in apoptosistic cell death. Once ignored completely or overlooked as cellular detritus, microRNAs (miRNAs) that were discovered only a decade ago, have recently taken many by surprise. The importance of miRNAs has steadily gained appreciation and miRNA biology has exploded into a massive swell of interest with enormous range and potential in almost every biological discipline because of their widespread expression and diverse functions in both animals and humans. It has been established that miRNAs are critical regulators of apoptosis of various cell types. These small molecules act by repressing the expression of either the proapoptotic or antiapoptotic genes to produce antiapoptotic or proapoptotic effects. Appealing evidence has been accumulating for the involvement of miRNAs in human diseases associated with apoptotic cell death and the potential of miRNAs as novel therapeutic targets for the treatment of the diseases. This editorial aims to convey this message and to boost up the research interest by providing a timely, comprehensive overview on regulation of apoptosis bymiRNAs and a synopsis on the pathophysiologic implications of this novel regulatory network based on the currently available data in the literature. It begins with a brief introduction to apoptosis and miRNAs, followed by the description of the fundamental aspects of miRNA biogenesis and action, and the role of miRNAs in regulating apoptosis of cancer cells and cardiovascular cells. Speculations on the development of miRNAs as potential therapeutic targets are also presented. Remarks are also provided to point out the unanswered questions and to outline the new directions for the future research of the field.Zhiguo Wang, Research Center, Montreal Heart Institute and Department of Medicine, University of Montreal, Montreal, PQ H1T 1C8, Canada 2010World Journal of Biological Chemistry2010,1,4:6

9Wg signaling in Drosophila heart development as a pioneering model显示文摘The heart is one of the first functional embryonic organs occurring during development. The fundamental developmental processes and genes involved in cardiogenesis are conserved between the invertebrates and vertebrates. In the past fifteen years, one of signaling pathways that has been best characterized in heart development in both invertebrates and vertebrates is the Wg/Wnt signaling pathways. Since our discovery of the Wg signaling required for the early heart development in Drosophila, the past fifteen years have witnessed tremendous progress in the understanding of specific Wnt signaling pathways in vertebrate cardiogenesis. This review will summarize the current state of knowledge of Wg signaling transduction in Drosophila heart development, which will benefit our understanding of vertebrate cardiogenesis and human congenital malformations.Xiushan Wu The Center for Heart Development, Key Lab of MOE for Developmental Biology and Protein Chemistry, College of Life Sciences, Hunan Normal University, Changsha, 410081, China 2010Journal of Genetics and Genomics2010,37,9:2
