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 explore the effect of bone marrow stromal cells (BMSC) transferred by Nell-1 gene combined with biomaterial fibrin glue (FG) to enhance segmental bone defect healing in dog mandible. Methods Nell-1 gene vector was reconstructed in retroviral vector and then transfected BMSC. The protein of Nell-1 gene in transferred cells was determined by immunohistochemistry. Segmental defects were created surgically in the dog’s mandible. The defect was repaired with BMSC transfected by Nell-1 retroviral granules in presence of FG,untransfected BMSC in combination with FG,and FG alone. The control group was left untreated. The defect-repairing capability for each treatment were assessed by gross observation,radiography,and histology at 8th week and 16th week. Results Cells transfected by Nell-1 retroviral granules expressed abundant Nell-1 mRNA and protein in the cytoplasm. Positive results were not found in those cells that were not transferred. The use of BMSC transferred by Nell-1 retroviral granules combined with FG materials exhibited the strongest defect-repairing ability. Gross observation,radiographical and histomorphometric analyses revealed a significantly greater total area of bone formation,increased amount of the new bone in the defects than in those treated with the untransfected BMSC. Conclusion Nell-1 gene transfection may be used to promote the osteogenic ability of BMSC.

ObjectiveTo explore the long-term fluctuation of fasting plasma glucose (FPG) and its effect on prognosis in patients surviving for more than 1 year after renal transplantation.MethodsFour hundred and forty-six patients underwent kidney transplantation from January,1993 to December,2008.According to preoperative FPG levels,patients were divided into diabetic,impaired fasting glucose (IFG),and normal fasting glucose (NFG)groups. The changing trend of FPG level was observed and analyzed. For 428 non-diabetic patients before transplantation,the prevalence and different outcomes of post-transplantation diabetes( PTDM ) according to FPG after transplantation were analyzed.The characteristics of the patients with persistent PTDM ( P-PTDM ) and transient PTDM (T-PTDM) were compared.The incidence of complications and patient survival between the PTDM group and non-PTDM groups were also compared.ResultsFPG level was increased early and then decreased in patients after renal transplantation.Of the 428 patients,87 developed into PTDM ( 20.3% ) including 15 T-PTDM patients ( 17.2% of total PTDM ),who eventually recovered to NFG or IFG.Compared with P-PTDM group,the incidence of acute rejection episodes was higher for T-PTDM ( P =0.043 ).The incidence of infections,hypertension,and dyslipidemia within the first year,was higher in PTDM group compared with non-PTDM group but patient survival was not different within a mean follow-up of ( 5.65 ± 3.68 ) years.ConclusionPTDM will not be permanent and may recover to NFG or IFG in the course of the disease.Acute rejections are associated with the onset of T-PTDM.The overall patient survival is not affected by PTDM,although complications,such as infections,hypertention,and hyperlipidemia are more frequently encountered in PTDM patients.

Objective:To explore the diagnosis and treatment of ketamine-associated urinary system dysfunction. Methods:Total-ly 56 cases of urinary tract symptoms with the history of ketamine abuse in recent years were retrospectively analyzed. The routine ex-amination and the examination related to the urinary system were given, and individual treatment was undertaken according to different situation. Results: The main symptom of ketamine-asscociated urinary tract dysfunction was lower urinary tract symptom (LUTS). Bladder pathologic biopsy showed different degree of inflammatory change. Imaging examination showed various degree of pathological changes, including reduced bladder capacity, thickened bladder wall, bladder contracture, ureteral stricture and hydronephrosis. Three patients had increased serum creatinine level. Conclusion: Ketamine-asscociated urinary system dysfunction is a disease with LUTS as the main clinical symptom. At the early stage, the disease is reversible with promising treatment outcome. In the progression of the disease, some patients develop irreversible histological changes in the urinary tract, which should be brought to the forefront.

Objective To investigate the association of serum angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2) with myocardial reperfusion in ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI). Methods A total of 103 consecutive STEMI patients who received primary PCI were enrolled in this study. The patients were divided into two groups according to ST-segment resolution (STR) at 2 h after PCI:STR ≥ 50%group (n=69) and STR<50%group (n=34). Serum concentrations of Ang-1, Ang-2 and Ang-2 to Ang-1 ratios (Ang-2/Ang-1) before and immediately after PCI, 2 h, 6 h, 24 h after PCI were compared. Predictors of poor STR were identiifed by multivariable logistic regression analysis. Results The patients with STR≥50%had significant higher serum Ang-1 levels (P < 0.05) and lower Ang-2/Ang-1 ratios (P < 0.01) from before PCI to 6 h after PCI than those with STR < 50%;Ang-1 and Ang-2/Ang-1 at 24 h after PCI, and Ang-2 at all time points were not signiifcantly different between the two groups (P>0.05). In multivariable logistic regression analysis, Ang-2/Ang-1 before PCI was independently associated with STR < 50%;Other independent predictors were pain to balloon time, infarct related artery (LAD), and TIMI flow grade<Ⅲafter PCI. Conclusions Higher Ang-2/Ang-1 is an independent predictor of poor myocardial reperfusion in STEMI patients after PCI.
