ObjectiveTo evaluate the immediate and 1-year outcomes of percutaneous coronary intervention (PCI) with domestically made drug-eluting stent (DES) in patients with previous coronary bypass graft surgery (post-CABG) in order to determine the relationship between related factors and major adverse cardiovascular and cerebral events (MACCE) after PCI. Methods From September 2008 to October 2009, 83 consecutive post-CABG patients had implantation of 176 domestically made DES for 126 coronary lesions. Each patient was followed up at least for 1 year after the procedure done for the evaluation of the efficacy and safety of DES implanted in post-CABG patients. Logistic regression analysis was used to determine the relationship between major factors and MACCE.Results The success rate of operation procedure was 97. 5%. MACCE occurred in 10 patients including death in 1 patient, stroke in 1 patient,myocardial infarction in 1 patient, and those were treated with repeated coronary revascularization in 8patients and target lesion revascularization (TLR) in 1 patient. ConclusionsImmediate and medium-term results showed the safety and efficacy of revascularization with domestically made DES in post-CABG patients. Complete revascularization was an independent predictor of MACCE.

AIM To investigate the relationship between the prevention of probucol against restenosis and functional vascular remodeling after percutaneous transluminal angioplasty(PTA) in rabbits. METHODS New Zealand rabbit thoracic aorta atherosclerosis was induced by 3 5 F balloon catheter injury following a 4 week feeding of high cholesterol diet, and percutaneous transluminal angioplasty(PTA) was performed by using 3 5 F ballon catheter. Probucol(1 g?d -1 ) or vitamin E(400 mg?d -1 ) was administrated one week before PTA. Two weeks after PTA, lumen area,neointima area(NEA),medial area(MA) and NEA/MA were analyzed by computerimage system.The relaxation response of restenotic arteries to acetylcholine and the contractive response to norepinephrine, potassium chloride and serotonin of thoracic aorta rings were measured by bioassay. Nitric oxide of serum was measured by means of biochemical assay.RESULTS After two weeks of PTA, probucol increased lumen area and decreased neointima area significantly. The relaxation response of restenotic arteries to acetylcholine was significantly lower than that of normal arteries〔relaxation percent to acetylcholine (1 ?mol?L -1 ):(18 4?4 0)% vs (63 5?6 4)%, P

Crohn's disease (CD) is a chronic nonspecific inflammatory disease.CD can affect any location in the digestive tract,and it also affect other organs,including the eyes,skin,liver and joints,which are termed extraintestinal manifestations (EIMs).The cutaneous manifestations of CD are common and occur in about one-third of patients.EIMs of CD have been divided into 3 categories.(1) Specific lesion,cutaneous manifestations of CD were the same as histopathologic findings of underlying gastrointestinal lesion.(2) Reactive lesion,it was also inflammatory lesion which was usually accompanied by underlying gastrointestinal disease while inflammatory injury was different from histopathologic findings of gastrointestinal lesion.(3) Associated lesion,it was caused by sequelae of human leucocyte antigen and chronic inflammation.In the current era of ever-expanding therapeutic options for CD,some investigators have proposed a fourth category of EIMs,namely those that are therapy-related lesion.The therapy-related lesion is closely related to disease-associated conditions in light of certain skin findings,and there is potential overlap between them.

Objective: To explore the efficacy of esmolol on cardiac ischemia in patients with serious coronary lesions who are not candidates for coronary revascularizations. Methods: Fifty seven aged patients (34 male) with serious coronary artery disease not candidates for coronary revascularizations were included. All patients had classical angina involved in cardiac ischemia, and definitely ischemic ST-segment depressions in surface electrocardiogram, however which were not relieved by routine treatment including intravenous nitrate or even morphine. All patients received loading dose injection and continuously intravenous infusion of Esmolol, and the baseline characteristics before treatment and the effects at 4 hours after infusion of Esmolol were carefully recorded. Results: After infusion of Esmolol, the ischemia-related symptoms of 41 patients completely relieved, and their ST depressions recovered to the baseline accompanied with significant reduction in blood pressure and heart rate (P<0.0001 all) within (66±23) min. Moreover, nine patients were observed that their ischemia-related symptoms were relieved and ST alteration recovered partially (P<0.0001 both) at four h after continuous infusion of esmolol. Conclusion: Esmolol is effective to relieve the serious cardiac ischemia-related symptoms and ST-T alteration of ECG in patients with serious coronary lesions.
