150?mol/L who underwent PTCA and/or coronary stenting were included (renal dysfunction group). Another 25 age and sex matched patients who had normal serum creatinine level and received coronary intervention at the same period were served as a control group. The status of coronary disease, procedural complications and long term prognosis were compared between the two groups. Results The number of patients with multi vessel disease (72% vs 48%, P

Objective To compare the effect of direct stenting (DS) and conventional post-dilation stenting (CS) on no-reflow phenomena in coronary artery disease (CAD) patients. Methods Demographic characters, final baloon dilation pressure instant angiographic results, and long term outcomes were compared between patients receiving DS (n=127) and patients receiving CS (n=127). Results Patients in DS group had less degree of stenosis (82%?6% vs 87%?11%,P

Objective To evaluate the efficacy and safety of percutaneous stent implantation for native aortic coarctation. Methods Five patients with native coarctation of the aorta underwent percutaneous endovascular angioplasty and stenting. Immediate and long-term outcomes were assessed in terms of blood pressure changes, procedure complications, and medications. Results Compared before and after stenting, the pressure gradient associated with the stenotic segment was decreased immediately after stenting [(73?6) mm?Hg vs (8?2) mm?Hg, P

70%) underwent successful stent implantation. Two weeks after interventional treatment, renal function was improved in 26 patients and blood pressure was well controlled in 24.Conclusions Age, hypertension and hyperlipidemia are the factors influencing occurrence of RAS in patients with CAD. Stent implantation plays an important role in the protection of renal function and control of hypertension.

Objective To evaluate the feasibility, safety and efficacy of ACS MULTI LINK PENTA (PENTA) stent in patients with coronary artery disease.Methods From March to June 2002, thirty PENTA stents were implanted in 28 patients with 30 de novo lesions. For each patient the demographic, interventional and mean 3 month follow up informations were recorded. Results Almost two thirds of patients suffered from hypertension(61%) and half experienced unstable angina (53%). Most target lesions(67%) had unfavorable morphological characteristics (type B2 or C). No stent deployment failure occurred as well as acute or subacute stent thromobis.The major branches compromised after stenting were only in 2 patients. During floow up,no MACE occurred, except reoccurrence of chest pain in 2 patients (7%). Conclusions The PENTA stent appears to be safe and effective in treating coronary artery disease.

Objective To evaluate the therapeutic efficacy of intra aortic balloon supporting in coronary interventions for high risk patients with coronary artery disease(CAD).Methods Sixteen high risk CAD patients accepted percutaneous coronary intervention assisted by intra aortic balloon pumping together with clinical variables, procedural and follow up informations were recorded and evaluated. Results All patients presented with severe left ventricular dysfunction, multi vessel disease and high jeopardy scores. 12 patients acquired complete revascularization. Mean duration of balloon pumping was (31?17) minutes. Aortic diastolic and mean pressures were increased during balloon pumping [diastolic:(69?11)mmHg pre.vs (131?15)mmHg post.; mean:(82?13)mmHg pre.vs (111?7)mmHg post., P

Objective To evaluate coronary flow reserve (CFR) in patients with myocardial bridging.Methods Between September 2000 and January 2003, thirteen patients were detected myocardial bridging(MB) by coronary angiography(MB group). Another 32 patients with normal coronary arteries were served as a control group. Demographic information and CFR were compared between the two groups. Results All patients in MB group were presented with stable angina pectoris, and the systolic and diastolic coronary compressing stenosis were 78%?7% and 15%?5%, respectively. CFR in MB patients was significantly lower compared with the controls(2.0?0.3 vs 3.3?0.6, P

70), hypertension and multi vessel coronary artery disease.Conclusions Selective renal angiography immediately after coronary angiography is feasible and safe, and it exerts great significance of detection of RAS.

Objective To study the effect of myocardial infarction induced by distal left ascending artery occlusion on left ventrieular(LV) synchronism. Methods Routine echocardiography and vector velocity imaging were performed within 2 hours before and 7-14 days after myocardial infarction by occluding distal left ascending coronary arteries in experimental pigs. Routine eehocardiographie parameters of LV, including end diastolic and systolic diameters, volumes, and spherical indexes were measured or calculated. Six segmental peak systolic velocity, strain and strain rate were compared between pre- and post-myocardial infarction. Results After myocardial infarction, LV end diastolic, end systolic long diameter and end systolic volume increased with decreased ejection fraction. With the 6 segmental systolic velocity, strain and strain rate significantly reduced,the mean 6-segmental time to peak strain rate delayed significantly. Conclusions Abnormal synchronism after myocardial infarction may aggravate LV systolic dysfunction.

OBJECTIVE To investigate the isolation rate and drug-resistance of Stenotrophomonas maltophilia so as to provide evidence for clinical rational use of drugs.METHODS The strains of S.maltophilia isolated from clinical specimens were identified and tested on drug sensitivity by the VITEK-32 system.Parts of the isolates were tested by disc diffusion method.RESULTS A total of 295 strains were identified during from Jan 2005 to Dec 2008.The most of the were isolated from sputum in clinical samples,and ICU was the main distribution department.The result showed that S.maltophilia had higher resistance rate to most drugs.Levofloxacin had the lowest resistance rate followed by trimethoprim-sulfamethoxazole and ciprofloxacin.CONCLUSIONS S.maltophilia has serious resistance rate to common antimicrobial agent showing mult-drug resistance.We should pay more attention to the status,and rationally choose antibiotics according to the drug susceptibility.
