Objective To study the cardiac electrophysiology changes of canine asynchrony ischemic heart failure under left ventricular endocardial pacing.Methods Left bundle branch radiofrequency catheter ablation and left anterior descending coronary artery ligation were used to establish the model of ischemic heart failure in 18 healthy dogs.Eighteen healthy dogs were randomly divided into two groups,9 cases in each group.The experimental group was treated with cardiac resynchronization therapy(CRT) in left ventricular endocardium,and the control group underwent the sham operation.ECG and echocardiography were done at 6 weeks after operation.Results The left ventricular ejection fraction in the experimental group was significantly higher than that in the control group(38.32 ± 6.08 vs.30.62 ±8.96).The asynchronization index in the experimental group was significantly lower than that in the control group(35.99 ±5.25 vs.78.21 ± 7.02),and the difference was statistically significant(P＜0.05).QRS(60.58 ± 7.43 vs.68.33 ± 8.01) and QTc(347.09 ± 17.33 vs.367.81 ± 22.02)in the experimental group were significantly shorter than those in the control group(P＜0.05);moreover Tp-e(37.03±9.07 vs.45.76±7.11) and ARI(162.33±22.06 vs.187.21±23.87) in the experimental group were significantly lower than those in the control group(P＜0.05).Conclusion Left ventricular endocardial pacing can produce preferably electrophysiological effects and achieve the goal of effective cardiac resynchronization therapy.

Objective To evaluate the effect of limited fluid resuscitation treatments on the hemorrhagic traumatic shock in order to improve the cure rate. Methods Forty cases of the hemorrhagic traumatic shock patient were randomly divided into the regular fluid resuscitation group (n=21, regular group) and the limited fluid resuscitation group (n=19, limited group). In regular group, fast infusion of the full quantity fluid underwent in the early stage before hemostasia, keeping systolic blood pressure ≥ 90 mm Hg 1mm Hg=0.133 kPa. In limited group, infusion of fluid was limited before hemostasia, keeping average MAP at 6.65 kPa, then blood transfuse and fluid infusion underwent after hemostasia. After hemostasia, two groups kept MAP at 9.31～10.64 kPa. Results Three cases died in regular group, and the cure rate was 85.7%. No death in limit group, and the cure rate was 100%. There was significance difference between two groups (P

Objective To evaluate the clinical application of superselective renal artery embolization in the treatment of iatrogenic renal hemorrhage. Methods The iatrogenic renal hemorrhage in fifteen patients was first demonstrated by renal arterigraphy to diagnose the rupture site and degree of injury. And then they were treated by percutaneous catheterized superselective renal arterial embolization through guidance of guide wire. Results In all 15 patients, the occlusive ruption of bleeding arteries and disappearance of extravasation staining were found after the superselective catheterized renal arterial embolization. Clinically, the bloody urine turned clear without macroscopic hematuria during 1-3 days in all patients after the procedure. Conclusions Superseclective renal arterial embolization treatment signified a less invasion, less complications, good hemostatic efficacy, and maximal preservation of renal tissue and function for iatrogenic renal hemorrhage. The treatment is worthy to be recommended.

Objective To study the efficacy and safety of transurethral plasmakinetic resection of prostate (PKRP) in treatment of benign prostate hyperplasia in elderly patients aged 80 years and over. Methods Retrospective clinical analysis of 180 case of high risk of benign prostate hyperplasia treated by PKRP in patients aged 80 years and over. Results All the 180 patients underwent the operation successfully. The average time for operation was (45.5±23.3) min and the resected prostate was in an average of (60.3±23.3) g. Neither of blood transfusion during the operation nor aductor reflex and transurethral resection syndrome occurred. International prostate symptom score,residual urine and quality of life decreased from (29.5±5.3) to (10.2±2.8),from (130.5±45.5) ml to (13.5±7.1)ml and from (7.2±1.1) to (1.0±0.5) respectively. The maximum flow rate elevated from (6.2±1.8) ml/s to (24.5±3.1) ml/s. The differences in the above indicators were statistically significant between pre- and post- operation (P＜0.05). Conclusions Transurethral plasmakinetic prostatectomy is a reliable and effective surgical method, especially for the aged patients with benign prostate hyperplasia.

Objective: To explore the effects of cardiac resynchronization therapy (CRT) in patients with dispersion of re-polarization and ventricular arrhythmia.
Methods: A total of 86 consecutive patents with CRT implantation were enrolled. According to weather absolute value of LVEF increased≥10% from baseline at 6 months after CRT implantation, the patients were divided into 2 groups: Response group and Non-response group,n=43 in each group. Dispersion of re-polarization indexes as QRS duration, QTc interval, TpTe interval and the events of ventricular arrhythmia were compared between 2 groups at different time points after CRT.
Results:①In Response group, compared with pre-operation, QRS duration and TpTe interval were shorter at 1 year and within 24h after CRT implantation, allP<0.05, while the above indexes were similar in Non-response group, allP>0.05.②During 1 year after CRT implantation, the incidences of PVCs and PVC runs in Response group were much less than those in Non-response group, for lgPVCs: (1.78 ± 0.77) vs (2.73 ± 0.61), for lgPVC runs: (0.64 ± 0.48) vs (1.98 ± 0.72),P<0.05.③Multi liner regression analysis demonstrated that TpTe interval within 24h after CRT implantation was an independent predictor for both lgPVCs: (B=0.143, OR=1.154,P=0.001) and lgPVC runs: (B=0.122, OR=1.047,P=0.001).
Conclusion: CRT ventricular reverse remodeling may reduce dispersion of re-polarization and the risk of ventricular arrhythmia, therefore improve the prognosis in relevant patients; TpTe interval within 24h after CRT had the predictive value for ventricular arrhythmia.

Background The data on the prognostic values of high sensitivity C-reactive protein (hsCRP) levels in patients with advanced symp-tomatic heart failure (HF) receiving cardiac resynchronization therapy (CRT) are scarce. The aim of present study was to investigate the association of serum hsCRP levels with left ventricle reverse remodeling after six months of CRT as well as long-term outcome. Methods A total of 232 CRT patients were included. The assessment of hsCRP values, clinical status and echocardiographic data were performed at baseline and after six months of CRT. Long-term follow-up included all-cause mortality and hospitalizations for HF. Results During the mean follow-up periods of 31.3 ± 31.5 months, elevated hsCRP (>3 mg/L) prior to CRT was associated with a significant 2.39-fold increase (P=0.006) in the risk of death or HF hospitalizations. At 6-month follow-up, patients who responded to CRT showed significant reductions or maintained low in hsCRP levels (–0.5 ± 4.1 mg/L reduction) compared with non-responders (1.7 ± 6.1 mg/L increase, P=0.018). Com-pared with patients in whom 6-month hsCRP levels were reduced or remained low, patients in whom 6-month hsCRP levels were increased or maintained high experienced a significantly higher risk of subsequent death or HF hospitalizations (Log-rank P<0.001). The echocardio-graphic improvement was also better among patients in whom 6-month hsCRP levels were reduced or remained low compared to those in whom 6-month hsCRP levels were raised or maintained high. Conclusions Our findings demonstrated that measurement of baseline and follow-up hsCRP levels may be useful as prognostic markers for timely potential risk stratification and subsequent appropriate treatment strategies in patients with advanced HF undergoing CRT.

Objective:To explore the efifcacy and safety for radiofrequency catheter ablation (RFCA) of left bundle branch guided by left bundle potential (LBP), X-ray image with EnSiteNavX System in canine model.
Methods:The RFCA of left bundle branch was conducted in 13 dogs. A mapping catheter was positioned in right atrium to record right-sided His-bundle (R-His) potential, and an ablation catheter via right femoral artery was retrograded to left ventriclefor LBP mapping and ablation. Meanwhile, EnSiteNavX System was used to identify R-His, L-His and LBP at the same time. The potential characteristics in dogs with successful ablation were observed, the PR interval, QRS shape and time limit, AH interval, HV interval, the A/V electro-gram ratio in ablationcatheter at before and after ablation were recorded. The procedural time and X-ray exposure time between LBP with X-ray image method and LBP, X-ray image with EnSiteNavX System method were compared.
Results: There were 9/13 dogs received successful left bundle branch ablation, 3 dogs failed and 1 suffered from complete A-V block. At the successful ablation target site, the LBP-V was (17.8 ± 2.6) ms with the range of (13-21) ms, and the A/V electro-gram ratio<1/10. The procedural time and X-ray expose time were signiifcantly decreased in LBP, X-ray image with EnSiteNavX System method than those in LBP with X-ray image method P=0.007 and P<0.001.
Conclusion:Under the LBP, X-ray image with EnSiteNavX System guidance method, left bundle branch could be safely and effectively ablated to establish left bundle branch block (LBBB) model in experimental canine.

Objective: To analyze the clinical features and outcomes of cardiac resynchronization therapy (CRT) in patients with dilated-phase hypertrophic cardiomyopathy (DHCM). Methods: A total of 16 DHCM patients received CRT in our hospital from 2007-03 to 2016-01 were retrospectively studied to analyze their clinical features and outcomes. Results: There were 12 male and 4 female patients at the mean age of (53.3±13.5) years. Pre-operative QRS duration of ECG was (158.7±32.2) ms, left ventricular ejection fraction (LVEF) was (33.6±6.3) %, the patient with NYHA class I, II, III and IV were 1, 5, 8 and 2 respectively. 13 patients received new CRT device, 3 received upgraded device and 8 (50%) combining atrial fibrillation (AF). The patients were followed-up for (2.56±2.13) years, 5 of them died including 3 of heart failure, 1 of sudden death and 1 of stroke. At 6 months follow-up time, 7 patients had the response to CRT which was defined by the improvement of NYHA class≥1 and the absolute elevation of LVEF≥5%; NYHA class improved from (2.69±0.79) to (2.38±0.89), P=0.02; LVEF increased from (33.6±6.3) % to (40.03±9.83) %, P=0.01. Conclusion: DHCM patients with CRT indication had the higher incidence to suffer from AF, those were more in patients with traditional pacemaker or ICD upgrading. DHCM patients with CRT had the poor general prognosis, while there was still certain proportion of patients had the response to CRT.
