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

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

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.

BACKGROUND:Studies have shown that there are large differences in the thickness of the soft tissue overlying hard tissue, and the soft tissue does not uniformly overly the hard tissue, indicating simple hard tissue measurement wil not harvest ideal facial profile in clinical treatment of malocclusions. OBJECTIVE: To study the craniofacial soft and hard tissue characteristics in the adult Angle class II malocclusion, and then to analyze the relationship between Angle class II1 and class II2 malocclusions. METHODS: Sixty patients with adult Angle II malocclusion who were accepted by the Department of Orthodontics of Stomatological Hospital Affiliated to Jiamusi University from 2011 to 2014, on gender parity, aged 18-38 years (mean age of 26.3 years), including 30 cases of Angle class II1 and 30 cases of Angle class II2. Differences between the adult Angle class II1 and class II2 malocclusion patients were compared by cephalometric analysis based on X-ray measurement. Statistical correlation analysis was performed.RESULTS AND CONCLUSION:(1) Comparisons of hard tissue measurement of adult Angle class II1 and Angle class II2 malocclusions showed that: SNB, SND, ANB, FH-NP, U1-SN (P < 0.001), LI-NB (P< 0.01), L1-MP (P < 0.01), U1-L1 (P < 0.001) exhibited statisticaly significant differences between two groups (P < 0.05). (2) Comparisons of soft tissue measurement of adult Angle class II1 and Angle class II2 malocclusions showed that: there were significant differences in the ULA'-FH, LLNs-FH, ULNs-FH, CmSnUL, E-LL (P < 0.05). (3) There was a correlation between the soft and hard tissue of adult Angle class II1 and Angle class II2 malocclusions in al measurement indexes, but the correlativity exists differently. These findings indicate that for Angle class II1malocclusion, the maxilary and anterior teeth protrusions have a certain influence on the position of the lower lip; for Angle class II2 malocclusion, only maxilary protrusion can impact the position of the soft tissue of the lower lip. Chin soft tissue has no major changes in Angle class II2 malocclusion, but it varies greatly in Angle class II1 malocclusion. Clinical treatment of adult Angle class II malocclusions is developed based on the craniofacial soft and hard tissue characteristics in orthodontic and orthognathic surgeries.
