AIM:To evaluate the therapeutic effects of treating chronic schizophrenia with ginkgo leaf capsule combined with comprehensive rehabilitation training. METHODS:110 chronic schizophrenia patients who had been treated with systemic antipsychotic for more than 12 weeks with unsatisfactory therapeutic effects and a long history of hospitalization were enrolled in this study. Ginkgo leaf capsule combined with comprehensive rehabilitation training was applied for 12 weeks and the therapeutic effects were evaluated. The positive and negative syndrome scale (PANSS) and treatment emergent symptom scale(TESS) for the side effects that needed to be treated during treating were used to evaluate the therapeutic effects and side effects. RESULTS:The treatment of ginkgo leaf capsule combined with comprehensive rehabilitation training was effective for the chronic schizophrenia patients with a long history of hospitalization,the total clinical effective rate was 96.36% and the cure rate together with the apparent rate was 67.27%,which were significantly better. CONCLUSION:Ginkgo leaf capsule improves the therapeutic effects of antipsychotic in the treatment of chronic schizophrenia and reduces the side effects,so it is a safe and effective drug for treating the chronic schizophrenia patients with a long history of hospitalization.

Objective To evaluate the effect of initial empirical antibiotherapy in CAP since the practice of the clinical path -way and the classification management of antibiotic and the analysis of sputum culture .Methods One hundred and sixty patients with CAP consistent with the clinical pathway were divided according to the preferred choice of empiric antibiotherapy , the results of disea-ses distribution, objective, number, therapeutic effect, drug distribution and sputum culture were listed .Results The most preferred antibiotic of initial empiric antibiotherapy were penicillins with a β-lactamase inhibitor, bibasic cephalosporin and respiratory fluoro -quinolone, it was identical with the recommendation of guideline and indirectly demonstrated that the pathogen of CAP was identical with the guideline.Conclusions The initial therapy of CAP is still depended on empirical antibiotherapy , the most CAP are cured by correct empirical antibiotharepy according to the guideline , the instruction effect of the pathogen detection of sputum to the therapy of CAP is limited.

Objective To evaluate and compare the therapeutic results of subclavian artery angioplasty and stenting in patients with aortoarerteritis and atherosclerosis. Methods 13 cases (9 males and 4 females; age, 28-69 years) of subclavian artery stenotic occlusive disease were performed with PTA and stent. Results Six patients had aortoarerteritis, 7 had atherosclerosis lesions. Twelve of 13 stenoses could be successfully angioplasty ( n =6) and stenting ( n =6) . The one failure was due to the inability to cross the lesion with the guidewrie. Compared with atherosclerosis, higher balloon inflation pressure was required to dilate the lesions of aortoarerteritis. 12 patients were asymptomatic after PTA and stent implatation. Patients were follow up for 3-24 months and clinical examination demonstrated patency of the vessels with PTA and stents. Conclusion Subclavian PTA and stent implatation is safe and good clinical result as in aortoarerteritis as in atherosclerosis.

Objective: To study the relationships between the expressions of E-cadherin and ki-67 in the tissues of heatocellular carcinoma(HCC)and the prognosis of HCC patients after hepatectomy as well as their clinical pathology. Methods: We examine the expressions of E-cadherin and ki-67 in 255 HCC tissues by tissue microarray and PV-6000 two-step method of immunohistochemistry and analyze the correlations between their expressions and clinical pathological data, 1-year recurrent rate and overall survival time after hepatectomy. Results: The expression of E-cadherin correlated with the tumor size and the 1-year recurrent rate of positive group was higher than that of the negative group. The expression of ki-67 correlated with vascular invasion and differentiation of the tumor, the positive group showed a higher 1-year recurrent rate and a shorter overall survival time. Multivariate Cox regression analysis indicated that the expression of ki-67 was an independent risky factor. Conclusions: The negative expression of E-cadherin and the positive expression of ki-67 predict a higher recurrent rate of early stage. The expression of ki-67 is an independent risky factor which can be used to evaluate the prognosis of patients with HCC after hepatectomy.

Objective Mechanisms of pulmonary vein isolation (PVI) for atrial fibrillation remain controversy.This study aimed to investigate the impact of PVI on vagal modulation to atria.Methods Eighteen adult mongrel dogs under general anesthesia were randomly divided into two groups.Bilateral cervical sympathovagal trunks were decentralized and sympathetic effects was blocked by metoprolol administration.Atrial electrical remodeling (AER) was established by rapid right atrial pacing at the rate of 600 bpm for 30 minutes.PVI was performed in group A.Atrial effective refractory period (ERP),vulnerability window (VW) of atrial fibrillation,and sinus rhythm cycle length (SCL) were measured at baseline and during vagal stimulation before and after atrial rapid pacing with and without PVI at fight atrial appendage (RAA),left atrial appendage (LAA),distal coronary sinus (CSd) and proximal coronary sinus (CSp).Results (1) Effects of PVI on vagal modulation:Shortening of SCL during vagal stimulation decreased significantly after PVI compared with that before PVI in group A (P＜0.001).Shortening of ERP during vagal stimulation decreaseed significantly after PVI compared with that before PVI (P＜0.05).VW of atrial fibrillation during vagal stimulation decreased significantly after PVI compared with that before PVI (P＜0.05).(2) Effects of PVI on AER:shortening of ERP before and after atrial rapid pacing increased significantly at baseline and vagal stimulation in group B compared with that in group A (P＜0.05).VW during vagal stimulation increased significantly after atrial rapid pacing in group B (P＜0.05).Conclusion PVI attenuates the vagal modulation to the atria,thereby decreases the susceptibility to atrial fibrillation mediated by vagal activity.PVI releases AER,which maybe contributes to the vagal denervation.Our study indicates that PVI not only can eradicate triggered foci but also modify substrates for AF.(J Geriatr Cardiol 2008;5:28-32)

Background Atrial electrical remodeling(AER)plays an important role in the pathogenesis and maintenance of atrialfibrillation.However,little is known about modulation of vagal activilty to AER.This study aimed to investigate the relationshipbetween vagal moduation and AER. Methods Twenty four adult mongrel dogs under general anesthesia were randomized into 3groups.Sympathetic activity was blocked by administration of metoprolol in 3 groups.The changes in vagal modulation to atria afterAER were observed in 10 dogs without vagal interruption in group A.The effects of vagal intervention on AER were investigated in 8dogs with administration of atropine in group B.The impact of aggressively vagal activity on AER was studied in 6 dogs with bilateralcervical vag sympathetic trunLks stimulation during AER in group C.Bilateral cervicall vagosympathetic trunks were decentralized.Multipolar catheters wereplaced into high right atria(RA),coronary sinus(CS)and rightventricle(RV).AER was induced by 600 bpmpacing through RA catheter for 30 minutes.Attial effective refractory period(ERP)and vulnerability window (VW)of atrial fibrillationwere measured with and without vagal stimulation before and after AER.Results In group A,ERP decreased significantly at baselineand during vagal stimulation after AER compared with that beforeAER(all P＜0.05).In group B,ERP remaind unchanged at baselineand vagal stimulation after AER compared with tbat before AER (all P＞0.05).In group C,ERP shortened significantly at baseline andvagal stimulation after AER compared with that before AER(all P＜0.05).ERP shortening after AER in Groups A and C increasedsignificantly than that in group B (all P＜0.05).Atrial fibrillation could not be induced at baseline(VW close to 0) before and after AERin three groups.VW became widen significantly during vagal stimulation after AER compared with that before AER in Groups A and C(all P＜0.05),while VW remained unchanged in group B (VW close to 0).Conclusions Short-term AER results in the decrease inERP.AER is accompanied by the increases in atrial vagal modulation.The increased vagal activity and vagal stimulation promote AER,thereby increase the susceptibility to atrial fibrillation.The interrupted vagal activity attenuates AER.thereby suppresses the atriaIfibrillation mediated by vagal stimutlation.

Objective To evaluate the imaging methods for cardiovascular malformations in Williams syndrome(WS).Methods Thirteen cases of WS(7 males and 6 females)aged 10 months to 13 years were involved in this study.All patients underwent chest X-ray radiography,electrocardiography.echocardiography and physical examination.3 cases underwent electronic beam computed tomography (EBCT),cardiac catheterization and angiography were performed in 8 cases.Results Twelve patients were referred to our hespital for cardiac murmur and 1 cnse for cyanosis after birth.7 patients were found with "elfin-like"facial features.6 patients with pulmonary arterial stenosis.2 Cases with patent ductus arteriosus.2 case8 with 8evere pulmonary hypertension and 1 case with total endocardial cushion defect.Sudden death occurred in 2 patients during and after catlleterization.respectively. Conclusions Conventional angiography is the golden standard for the diagnosis of cardiovascular malformations in WS.Noninvnsive methods such as MSCT and MRI should be suggested because of the risk of sudden death in conventional angiography.

The Long-term Thromboembolic Event Analysis in Atrial Fibrillation Patients With Radiofrequency Catheter Ablation
Objective: To observe the thromboembolic event in atrial fibrillation (AF) patients with long-term successful radiofrequency catheter ablation (RFCA), and to study the relationship between thromboembolic event and CHA2DS2-VASC score in order to guide the anticoagulation strategy for AF patients.
Methods: A total of 321 AF patients who received RFCA in our hospital from 2000-01 to 2009-05 were studied. There were 261 patients with paroxysmal AF and 60 with persistent AF, they were followed-up for (66.7±26.9) months. The patients were divided into 2 groups according to AF recurrence condition as Non-recurrence group, n=204 and Recurrence group, n=117. The relationship between thromboembolic event and CHA2DS2-VASC score was studied.
Results: The Non-recurrence group had significantly lower rate of thromboembolism than that in Recurrence group (1.96% vs 7.69%), P=0.017. In both groups, the patients with CHA2DS2-VASC score < 2 had much lower rate of thromboembolism than those with CHA2DS2-VASC score ≥ 2, (0% vs 5%), P=0.023 and (4.45% vs 17.24%), P=0.041. The patients with CHA2DS2-VASC score<2 in Non-recurrence group had lower rate of thromboembolism than those in Recurrence group (0%vs 4.45%), P=0.029. The rate of thromboembolism had no statistic meaning between 2 groups in patients with CHA2DS2-VASC score≥2 (5%vs 17.24%), P=0.054.
Conclusion: The AF patients who received RFCA without AF recurrence in long-term follow-up had the lower rate of thromboembolic event, CHA2DS2-VASC score was important for evaluating such event. The patients with CHA2DS2-VASC score < 2 could consider stopping warfarin anticoagulation, while the patients with CHA2DS2-VASC score ≥ 2 might be beneifted for warfarin anticoagulation.

Objective To evaluate the imaging diagnosis of anomalous origin of coronary artery from the pulmonary artery(ACAPA).Methods A total of 11 cases with ACAPA were included in the present study.Chest films,echocardiography,cardioangiography,and electron beam computed tomography (EBCT) were employed as diagnostic modalities.Macroscopic anatomy at operation was referred. Results Ten cases were classified as anomalous origin of left coronary artery from the pulmonary artery(ALCAPA) and 1 case as anomalous origin of right coronary artery from the pulmonary artery(ARCAPA).They could not be diagnosed by chest films,but could be diagnosed by echocardiography in 3 cases,by EBCT in 1 case,and by cardioangiography in all cases.In ALCAPA,cardioangiography showed that the left coronary arteries arising from the posterior sinus or posterior wall of the pulmonary artery were perfused retrogradely via the collaterals from the dilated right coronary artery.In ARCAPA,the right coronary artery originated from the right sinus of the pulmonary artery.Gross anatomy at operation showed that the sites of the anomalous origins were the same as that of cardioangiography.Ischemic fibrosis of the anterior papillary muscles,mitral valve annulus enlargement,and prolapse of mitral valve,which led to mitral valve insufficiency,were found in 3 cases.Conclusion Chest film has limitation in the diagnosis and echocardiography should be further improved.Cardioangiography remains the “gold standard” of the preoperative diagnosis.
