Objective To evaluate the effectiveness and safety of a new designed balloon catheter, the Minirail balloon catheter in coronary intervention Methods Twenty two consecutive patients with coronary artery disease (male 16, female 6, mean age 58 77?8 69 years) were enrolled the study Selective angioplasty was performed for 24 target lesions (17 in LAD, 2 in LCX, and 5 in RCA) Among these target lesions were 5 type C, 14 type B 2, and 5 type B 1 lesions The average extent of narrowing before procedure was 91 18%?5 95% Target lesions were dilated with Minirail balloon catheters Results All of the target lesions were successfully dilated with Minirail balloon catheters The average residual stenosis was 33 18%?25 14% after balloon angioplasty Significant dissection was seen in 3 of the cases, and slow reflow in another one Twenty four stents were implanted in 19 cases The final residual stenosis was 1 82%?5 01% at the end of procedure No death or Q wave myocardial infarction happened No emergency bypass surgery needed Conclusion Minirail balloon catheter is safe, effective, and easy to be used in coronary intervention

Objective To evaluate the efficiency and safety of Percusurge guardwire distal protection system in coronary intervention in patients with acute myocardial infarction. Methods Three male patients with acute myocardial infarction were enrolled in the study. Primary angioplasty was performed for 2 of them, 2 and 7 hours after onset of the infarction symptom, respectively. Selective angioplasty was performed 17 days after infarction for the third case. Percusurge guardwire system was used during the procedure. Results Procedure success was achieved for all of the 3 cases. Lot of thrombus was sucked out. The infarct-related arteries had TIMI 3 flow at the end of the procedures. The patients′ symptoms were resolved soon after the procedure. Minor dissection was seen in one case which did not obstruct the distal flow and was left alone. Conclusion Percusurge guardwire system can be used safely and effectively in coronary intervention in the thrombus-laden arteries such as acute myocardial infarction.

Objective To evaluate the clinical outcome of patients who suffered from acute myocardial infarction with angiographically normal coronary arteries (MINC) Methods Forty patients (mean age: 52 6?12 2 years; range: 30-75 years) admitted with acute myocardial infarction had normal coronary arteries after AMI, defined by normal or insignificant 50% diameter stenosis) The risk factors, clinical data, ventricular functions and the long term outcomes were compared between Group A and Group B Results Hypertension and previous angina were more frequent in Group B Patients in Group A had a lower number of risk factors associated with them than patients in Group B LVEF during hospital was higher in Group A than in Group B The mean follow up period was 67?40 months in Group A and 68?34 months in Group B Incidencs of rehospitalization, repeat intervention therapies, heart failures, and total heart events were fewer in Group A than in Group B Conclusion These data suggest a favorable long term prognosis and fewer risk factors in patients who suffered from acute myocardial infarction with normal or nearly normal coronary arteriogram

Objective To explore the mechanisms of recovery from aphasia by using speech-activated single photon emission computed tomography(SPECT)brain imaging.Methods The SPECT brain imaging of 7 aphasic patients caused by various brain disorders were performed while they were at rest and performing oral reading,respec- tively,with an one-day interval.A semi-quantitative analysis of regional cerebral blood flow(rCBF)was conducted using region of interesting(ROI).The change of rCBF before and after reading was calculated and compared to ana- lyze the role of both hemispheres in the recovery from aphasia.Results It was found that the activation pattern of brain region was associated with the speech performance of the patients.The activated brain regions were mainly loca- ted at the left hemisphere in 5 patients whose reading capacity was relatively better,and mainly at the right hemi- sphere in the other 2 patients who had poor performance in reading.Conclusion After a focal lesion of the left hemisphere,the recovery of speech function might be mainly attributed to the repair of the damaged left hemisphere language network.When the left-hemispheric centers were permanently impaired,the brain would recruit some right- hemisphere regions for speech processing,but this strategy was less effective than the repair of the original speech-rel- evant network.

objective:To study the etiopathogenisis、clinical features、diagnosis and treatments of monostotic fibrous dysplasia of the sphenoid sinus. Method:Two cases of monostotic fibrous dysplasia of the sphenoid sinus without any symptoms was reported with relevant literature review.Result: No aggravation was found after 6 months-follow-up.Conclusion:The cranial fibrous displasia has low incidence rate with non-specific symptoms and high rate of misdiagnosis. The monostotic fibrous dysplasia of the sphenoid sinus without any symptom is rarely seen clinically. Imageological examination,for example,CT and MRI,is valuable for the diagnosis of this disease. The histopathological evidence is absolutely necessary to make definite diagnosis. The conservative treatment may be chosen for the asymptomatic cases. Nasal Endoscopic surgery can not only remove the diseased region but also make diagnosis.The long-term follow-up should be carried out in all of these patients.
