Objectives To explore the effects of hemodialysis on oxidizing stress and plasma nitrogen monoxide (NO) levels in maintenance hemodialysis patients. Methods 67 maintenance hemodialysis patients (male 39, female 28, and mean age 58?13y) were enrolled in this study. Serum malondialdehyde (MDA) level was measured by colorimetry, and plasma NO level was determined by enzymatic method. The MDA and NO levels before and after hemodialysis were measured in 48 cases of the patients. Results After hemodialysis, the serum MDA levels significantly increased, and the plasma NO levels decreased. The patients with cardiovascular diseases had lower NO levels and higher MDA levels than the patients without ones before hemodialysis. The serum MDA levels of the patients using biological incompatible dialysis membrane increased after hemodialysis. Conclusion Hemodialysis treatment, especially using biological incompatible dialysis membrane increased oxidizing stress and decreased plasma NO levels in maintenance hemodialysis patients, and was significantly correlated with the pathogenesis of cardiovascular diseases.

Objective To further identify the isolated Mycoplasma genitalium (Mg) from the high risk population of STD in China. Mothods The morphology of Mg standard strains and clinical isolates were observed under electron microscopy (EM) and atomic force microscopy (AFM). Mg sample preparation for AFM was fixed on mica and AFM images of scanning observation were captured by contacting and tapping modes and operated under normal atmospheric pressure and temperature. Results and Conclusion Mg had a diversity of shapes, including flask, pear, spindle or round shape with projecting neck portion and slightly broadened terminal structure under EM. The morphologic features under AFM were similar to those observed by EM. The typical Mg showed shapes of flask and pear with noticeable narrow ring or mark in the neck portion. The size of Mg measured under EM and AFM was similar as well. Mycoplasma

Objective To investigate the possible mechanism and re-ablation of recurrent atrial arrhythmias after atrial fibrillation(AF) ablation by utilizing the Carto system and double LASSO technique.Methods A total of 77 AF patients were enrolled and among them,56 with paroxysmal AF and 21 with persistent AF.Eight-F Swartz long sheaths were positioned in the left atrium by transseptal technique.One to two LASSO catheters were placed in the ipsilateral pulmonary veins(PV).The anatomy of the left atrium and PV was established using the Carto system.PV selective venography was carried out to identify the PV ostium.Continuous circular lesions(CCL) were made at the left atrium at 0.5 to 1.0 cm outside the PV ostium.Irrigated radiofrequecy energy was delivered in all the patients.The end point of the CCL was defined as absence of all PV spikes documented with LASSO catheters within the ipsilateral PVs.Results A repeat ablation was performed in 14 patients who experienced highly symptomatic atrial tachyarrhythmia.During the repeat procedures,conduction gaps in the previous CCL were found in 13 out of the 14 patients,and a typical atrial flutter was found in the other patient which was eliminated by ablation of the tricuspid isthmus.During the second procedure,pulmonary vein tachycardia was demonstrated in 7 patients.The pulmonary vein tachycardia activated the LA via the conduction gaps.All conduction gaps were successfully ablated by irrigated RF applications.After the second procedure,12 out of the 14 patients were free of AF during 3 to 30 months of follow-up.Conclusion Continuous circular lesions(CCL) in the left atrium utilizing the Carto system and double LASSO technique had a high success.In patients with recurrent atrial tachyarrhythmia after CCLs,recovered PV conduction is a main cause for the recurrence.
