Objective To investigate the gender differences of coronary heart disease secondary prevention status in patients post percutaneous coronary intervention (PCI). Methods Patients diagnosed with coronary heart disease from 31 tertiary hospitals were enrolled for a baseline survey. Medical history and laboratory tests were taken. Analysis was done for outpatient or inpatient with the history of at least one PCI treatment. Status of smoking cessation, weight management, blood pressure < 140/90 mm Hg, low-density lipoprotein cholesterol (LDL-C) < 100 mg/dL (2.6 mmol/L), and use of antiplatlet drugs, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARB) and statins were collected and compared. Results Women (n=1151) accounted for 25.4% of all PCI patients (n=4532). Proportion of female with history of smoking was signiifcantly lower than male, but the proportion of quitting was similar between female and male, 53%(n=98) vs. 53.7%(n=1344), P=0.849. The average body mass index, mean waist circumference and proportion of overweight were higher in man than women, P=0.000. However, the proportion of abdominal obesity in women is higher than men, 75.2%vs. 52.8%, P=0.000. More female were comorbid with hypertension, hyperlipidemia and diabetes than male and the differences were signiifcant, P=0.000. Control rate of blood pressure, LDL-C and fasting glucose were lower in women than in man, the differences were 66.2% vs 73.4% for blood pressure, 47.8%vs. 57.0%for LDL-C and 57.5%vs. 62.7%for fasting glucose, P=0.000. There was no signiifcant difference in medication usage between different genders. Conclusions In patients post pecutaneous coronary intervention, female patients had more risk factors than male while risk factor control rate was lower comparing with male. Medication usage for coronary heart disease secondary prevention was similar between different genders.

Objective:To explore the efficacy and safety of Rasburicase therapy in critically ill children su-ffering from advanced Burkitt′s lymphoma.Methods:A retrospective analysis of children with advanced Burkitt′s lymphoma was admitted to Pediatric Intensive Care Unit, the First Affiliated Hospital of Sun Yat-Sen University, from January 2015 to May 2020 and accepted treatment.According to the uric acid-lowering therapies, patients were divided into 2 groups, namely Rasburicase group (Group R) and traditional treatment group (Group T), to compare the effects of hypouricemic treatment and the prognosis between the 2 groups.Results:Twenty-nine children with advanced Burkitt′s lymphoma were included in this study, with 13 cases (44.83%) of stage Ⅲ and 16 cases (55.17%) of stage Ⅳ.Abdominal mass/ abdominal distension (13 cases, 44.83%) and abdominal pain (7 cases, 24.14%) were the main reasons of initial medical visit attendance.The most common primary tumor site was abdominal/ pelvic cavity (21 cases, 72.41%), followed by head or neck (6 cases, 20.69%). There were 15 cases in Group R and 14 cases in group T. No significant differences in serum creatinine, lactate dehydrogenase and uric acid were detected between the 2 groups (all P>0.05). The proportion of serum uric acid recovery rate of 24 hours and 72 hours after initial treatment in Group R were significantly higher than those in T group (85.71% vs.25.00%, 100.00% vs.25.00%, all P<0.01). Although there were no obvious differences in the incidence of tumor lysis syndrome between the 2 groups (33.33% vs.64.29%, P=0.096), the incidence of acute renal injury, renal replacement therapy requirement, serious complications and the 28 day mortality in Group R were remarkably lower than those in Group T (33.33% vs.85.71%, 13.33% vs.64.29%, 20.00% vs.78.57%, 0 vs.35.71%, all P< 0.05). Conclusions:Rasburicase can effectively reduce the serum uric acid level and decrease the incidence of acute kidney injury and other severe complications, thus improving the prognosis of children experiencing advanced Burkitt′s lymphoma.

ObjectiveAnalyzing the left atrium and pulmonary vein morphologicallv by 64 multislice spiral CT(MSCT)scan to guide the catheter ablation of Atrial fibrillation.MethodsTwo hundred and thirty-two patients(146 cases in atrial fibrillation group and 86 cases in control group)received 64 MSCT examination of the left atrium and pulmonary vein.The incidence of anatomical variation of pulmonary vein was compared between atrial fibrillation group and control group. For each group,the anatomical morphology ot every pulmonary vein and the auricle of left atrium was analyzed, the diameter of the orifice of each pulmonary vein and the size of left atrium were measured.ResultsSixty-four MSCT of left atrium and pulmonary vein could demonstrate detailed connecting type between left atrium and pulmonary Veins and the possible anatomieal variation. Anatomical variation of pulmonary vein in this study accounted for 16.8% (39/232)of total sample. For both groups,orifices of pulmonary veins appeared oval and their superoinferior diameters were larger than their anteroposterior diameters. There was significant difference in the inner diameter of left atrium between atrial fibrillation group and control group[atrial fibrillation group:(39.47±8.98)mm,control group:(36.94 ±5.49)mm,P=0.02],while there was no difference in the diameters of orifices ot puhnonary veins between two groups [ superoinferior diameters of pulmonary veins in atrial fibrillation group:left-up(18.15±1.35)mm,left-down(16.96 ±1.18)mm,right-up(17.50±

ObjectiveTo evaluate the efficacy of short-segment transpedicular fixation combined with augmentation vertebroplasty in treatment of thoracolumbar burst fractures. MethodsFrom November 2006 to September 2009, 37 patients with thoracolumbar burst fracture were admitted and received transpedicular fixation combined with calcium sulfate cement augmentation vertebroplasty, and the clinical data including fracture types, complications and following-up results were collected for analysis. The multimethod evaluation strategies involved the anterior vertebral body height, the sagittal Cobb's angle, the restoration of nervous function, internal fixation failure, visual analogue scale (VAS) and Oswestry disability index (ODI) were retrospective analyzed. Results All patients were followed up for average 19 months (range, 14-37). There were no internal fixation failure, loss of reduction, neurological complications in all the patients. In 16 patients with partial neurologic deficits, 14 initially improved at the final follow-up, with no deterioration of neurologic functions. The mean time of calcium sulfate cement obvious absorption and union was 3 months and 5 months postoperatively, respectively. The anterior vertebral body height was 55.40％before surgery and 85.46％ after surgery on average, ended up with 82.35％. The sagittai Cobb's angle was improved from 22.45° to 6.86°, ended up with 9.66° on average. The mean VAS and ODI at the final followup were respectively 1.2 and 20.4 on average. ConclusionShort-segment transpedicular fixation combined with augmentation vertebroplasty appears to be effective in achieving stable biomechanics with high security,which seems to be a feasible option in the management of thoracolumbar burst fractures.

Objective To identify the electrophysiological charateristics and cause of ridge gap related reentry after MI ablation in atrial ifbrillation patients. Methods Activation and entrainment mapping was performed in 82 redo cases for OAT recurrence in whom MI was ablated during the index produre. Once ridge gap related reentry was conifrmed, detailed mapping was performed in MI and ridge region. In addition, in 36 cases undergoing MI ablation and fulfilling criterion for bidirectional block, differential pacing was repeated at the ridge to identify a ridge gap. Results Out of 82 redo cases for OAT recurrence in whom MI was ablated during the index produre, 7 (8.5%) was found to be ridge gap related reentry. TCL was (247.9±19.2) ms, and the left atrial endocardial activation time was (145.4±17.7) ms, accounting for (58.5±3.2)%of TCL. However, wide double potential was recorded along the previous ablated MI line where PPI was (34.3±6.6) ms longer than TCL, while PPI was signiifcantly shorter at the ridge[PPI-TCL (11.4±3.9) ms, P<0.001]. Tachycardia was terminated at the ridge in 6 cases and at the corresponding site in coronary sinus in 1 case. No recurrence was found during follow-up for (11.1±4.5) months. In addition, in 36 patients undergoing MI ablation in whom criterion of bi-directional block was fuliflled, conduction gap located at the ridge was found in 5 (13.9%) cases. Conclusions MI ridge gap related reentry is a distinctive OAT, in which the ridge was used as the critical isthmus, whereas the previous ablated MI line is not part of the reentry. MI pseudo-block due to the ridge gap may lead to this type of recurrent tachycardia.

Objective To observe the management and outcome of the cardiac tamponade patients during the ablation procedure using two different anticoagulation strategies. Methods All the patients developed tamponade during the ablation procedure were enrolled from January 2007 to December 2013 in our center. In group 1, warfarin was discontinued 3 to 5 days before the procedure and low molecular weight heparin (LMWH) was administered subcutaneously until ablation procedure day. In group 2, warfarin was not discontinued and the international normalized ratio INR was to maintained between 2 and 3. Results There were 27 patients (0.6%) developed cardiac tamponade out of a total 4487 patients received ablation in our center. The baseline clinical characteristics including age, left atrium, the heparin dose and ACT during the procedure had no signiifcant difference between the groups, except that the INR was higher in the group 2 (0.9±0.1 vs. 2.3±0.5, P<0.001). There was no signiifcant difference in the amount of pericardiac drainage between the two groups (365±222 ml vs. 506±300 ml, P=0.137). Two patients in group 1 patient (11.1%) and 1 in group 2 (11.1%) needed emergency surgical repair (P>0.999). The median hospital day was similar in the 2 groups [(9.6±3.3) d vs. (12.1±4.5) d, P=0.167]. There were no other serious complications and no hospital death. Conclusions Non-discontinuation of warfarin during peri-procedural catheter ablation of AF is not signiifcantly different to bridging with LMWH in the management and outcome of acute cardiac tamponade.

Objective Identify the mechanism of induced atrial arrhythmias after pulmonary vein isolation (PVI) in patients with paroxysmal atrial ifbrillation(PAF), and investigate its long-term prognosis. Methods All patients with PAF undergoing PVI and induction test afterwards between Feburary 2010 and October 2010 were included. The induction protocol was rapid pacing initiated at cycle length of 250 ms with progressive shortening in a decrement of 10 ms down to 180 ms or refractoriness. Isoproterenol of 2-4μg/min was administrated as well. Inducibility was deifned as induction of atrial arrhythmia lasting >1 min. The mechanism of induced tachycardia was identiifed by activation mapping and entrainment mapping under the guidance of CARTO system. All patients were followed up by 36 months. Results Forty-nine atrial tachycardia were induced in 39 (19.7%) patients, including 35 organized atrial tachycardia (OAT) and 14 atrial ifbrillation (AF). The LA diameter was signiifcantly larger in inducible group than non-inducible group (39.5±6.6 mm vs. 36.7±5.2 mm, P=0.004). Macroreentry was the most common mechanism in induced OATs (28, 80.0%), and mitral isthmus was the most common critical site (20, 40.8%), followed by cavo-tricuspid isthmus (12, 24.5%), PV (6, 12.2%), LA septum (4, 8.2%), superior vena cava (3, 6.1%) and LA roof (1, 2.0%). Conclusions The most common mechanism of induced tachycardia by IV isoproterenol and rapid pacing is MI and CTI dependent after PVI in PAF patients, which can be succssefully eliminated by liner ablation, not increasing long-term recurrence rate.

Objective The recurrence of perimitral atrial tachycardia is common after initial ablation of persistent atrial fibrillation (AF). The aim of the study is to explore a preferable ablation approach for perimitral atrial tachycardia in the redo ablation of persistent AF. Methods Seventy-four patients with perimitral atrial tachycardia after initial ablation for persistent AF were included in our study. Patients were distinguished into either the group of having ablation during tachycardia (Group A) or the group having ablation after cardioversion to sinus rhythm (Group B) according to the different ablation strategies. The procedural endpoints were pulmonary vein isolation and bidirectional conduction block of all the ablated lines. The primary endpoint of the study was freedom from atrial tachyarrhythmia recurrence during the follow-up period. Results There were statistical differences in baseline clinical data between the 2 groups. During the redo procedure, conduction recovery rate across the mitral isthmus (MI),cavotricuspid isthmus and left atial roofline were 100％, 40.5％ and 48.6％ respectively. The procedural time, fluoroscopy time, mapping time were longer in the patients of group A. During a mean follow-up of (16.9±6.3) months, 31 (72.1％) patients in group A and 21(67.7％) patients in group B maintained in sinus rhythm in the absence of antiarrhythmic durgs (P =0.771) . Conclusion In patients with perimitral atrial tachycardia after initial ablation for persistent AF,ablation in sinus rhythm is a more simplified method and as effective as ablation during tachycardia.
