Objective The cardiac synchronization therapy (CRT) was proven to have good treatment for the cardiac conduction disorders patients with serious heart failure. But many disadvantages were gradually be noticed, such as difficulty of sinus electrode implantation, coronary sinus injury and bleeding, still one third CRT cases remain unchanged cardiac function.Recently the epicardial lead CRT therapy by the cardiac surgeons appears promising to provide better clinic resynchronization.The aim of this research is to explore the clinical value of surgical epicardial lead CRT for the cardiomyopathy heart failure with micro-invasive thoracoscopy techniques. Methods During April 2007 to Sep 2009 eleven patients were diagnosed as advanced heart failure with cardiac dysynchronization proven by the ECG and tissue Doppler echo examination. The dysynchronization parameters of tissue Doppler echo includes left ventricle maximize delay time , the left dysynchronization index (Ts-SD), the inter-ventricle mechanical delay time (IVMD), left ventricle end-dilation diameters (LVEDD) and the left ventricle ejection fraction (LVEF). All the patients got the consent agreement before the surgery. In the hybrid operation room the right atrial and ventricle endocardial electrodes were placed firs guided by X ray under the general anesthesia and double lumnen incubation. Then the thoracoscope techniques were used to explore the left ventricle lateral wall. The right atrial and ventricle electrodes were connected into the three chamber pacemaker. The Tissue Doppler Echo TEE technique was used to check which part of the left ventricle lateral wall is suitable for the idea CRT therapy. Usually the latest activated part of the left ventricle wall is the goal place. Then the epicardial electrode was fixed with 4-0 prolene suture at the idea place. All the cases were performed by the same surgeons group in the same medical center. The resynchronization features were examined after surgery and during the follow up. Results The endocardial and epicardial electrodes were implanted successfully without any serious complication. All patients were weaned and discharged without any adverse cardiac episodes. There is no mortality during the follow up period. All the patients received the β-blokers, diuretics, ACEI/ARB and other traditional medicine for the heart failure.The Tissue Doppler showed the E peak wave separated form the A peak which means the good resynchronization between the atrium and the ventricle. After surgery during the follow up the left ventricle maximize delay time decreased from (393.4 ±40.2 ) ms to ( 102.1 ± 34.6) ms, the left dysynchronization index (Ts-SD) decreased from (145.2±29.3)ms to(51.0±21.4) ms, the inter-ventricle mechanical delay time (IVMD) decreased from (59.1 ±23.4) ms to (31.2 ± 11.5 ) ms, left ventricle end-dilation diameters increased from (73.1 ± 13.4) mm to (63.2 ± 6.7) mn and the left ventricle ejection fraction increased from 0.32 ±0.04 to 0.41 ±0.07. Conclusion The micro-invasive surgical synchronization therapy could get good CRT result for the cardiomyopathy heart failure patients. Some patients traditionally in the waiting list for the heart transplant could be considered for the CRT therapy candidates.

One hundred patients with Parkinson's disease (PD) aged 60 and above treated with levodopa were enrolled in this cross section study.The general conditions,medication,unified Parkinson's disease rating scale (UPDRS) scores and the incidence of levodopa-induced dyskinesia (LID) were documented.The incidence rate of LID in this group of PD patients was 37.0％ (37/100).The incidence was significantly higher in patients with levodopa treatment ≥ 4 years than that in patients with levodopa treatment ＜ 4 years (55％ vs.26％,x2 =8.770,P =0.003).The incidence rate ofpeak dosage dyskinesia in tremor-dominant PD patients was lower than that in rigidity-dominant PD patients(x2 =4.399,P =0.036).The incidence rate of LID was correlated with the duration of levodopa therapy.Amantadine may reduce the incidence of off dystonia.

To explore the safety of ropinirole in the treatment of Parkinson′s disease( PD).A total of 221 PD patients participated in a multi-center,12-week randomized,bromocriptine-controlled,double-blind, double-dummy and parallel-group trial.The safety was assessed on the basis of adverse reactions , blood pressure,pulse,laboratory parameters and electrocardiography recordings.The incidence of adverse reaction was 34.9%in ropinirole group and 34.8% in bromocriptine group.And the frequency of adverse reactions had no inter-group statistical significance (χ2 =0.000,P=0.995).Ropinirole has an excellent profile of safety in the treatment of Chinese PD patients.

Objective To evaluate the role of multi-slice computed tomography (MSCT) in the diagnosis of pulmonary sequestration.Methods MSCT scans of 18 cases of pulmonary sequestration proved by surgery and pathology were reviewed.All cases underwent plain and contrast enhanced CT scanning,and retrospective reconstruction was made.Various reconstruction techniques in displaying the pulmonary sequestration and associated malformation were evaluated.Results Anomalous systemic arterial supply was discovered by transverse CT images in 12 cases.The reconstructed images using multiple methods showed the aberrant artery more clearly in all cases,including 6 cases in which the abnormalities were not confirmed by transverse CT.Drainage vein was revealed in 13 cases and lung heteroplasia with other malformation was demonstrated in 14 cases.Volume rendering (VR) reconstruction is the optimal choice for displaying the abnormal vessels and airway.Conclusion Enhanced MSCT with image post-processing can show the abnormal artery and vein of the pulmonary sequestration and the associated malformation,so it is the first choice in diagnosing pulmonary sequestration in pediatric population.
