To study the electrophysiological mechanism of atrial fibrillation induced by acetylcholine(Ach). The results showed that:①Ach decreased ERP of four atrial sites.When the concentration of Ach was incseased, ERP of 4 sites became shorter but COVERP became bigger.②As the concentration of Ach was increased, the percent of AF induced by Ach and AF was increased with the duration prolonged( P 0 05).③There was a significant correlation between atrial vulnerability with ERP and COVERP( P

BACKGROUND: Radiofrequency catheter ablation (RFCA) in dog triggers myocardial nerve sprouting and sympathetic hyperinnevation. It is possible that RFCA in humans has the same effect. Nerve growth factor (NGF) is a neurons nurture that supports the survival and differentiation of sympathetic neurons and enhances target innervation. Therefore, it is hypothetic that RFCA can increases plasma NGF concentration in humans.OBJECTIVE: To test the hypothesis that RFCA increases plasma NGF concentration in humans.DESIGN: Self-control experiment.SETTING: Department of Cardiology, Tangdu Hospital, the Fourth Military Medical University of Chinese PLA.PARTICIPANTS: Forty-three patients were selected from the Cardiological Department of Tangdu Hospital, the Fourth Military Medical University of Chinese PLA from January to June 2005, including atrioventricular nodal reentrant tachycardia (AVNRT) (n=18), right-sided accessory pathways (RSAP) (n=13) and left-sided accessory pathways (LSAP) (n=12), 20 males and 23 females, ages 28-65 years, all agreed to participate in the study voluntarily.METHODS: Blood samples were obtained from the peripheral veins before ablation and at 6 hours, 1, 3, 5, 7 days after ablation. The plasma concentration of NGF was determined with enzyme-linked immunosorbent assay (ELISA).MAIN OUTCOME MEASURES: The plasma concentration of NGF was determined with ELISA before RFCA and at 6 hours, 1, 3, 5, 7 days after RFCA in each patient.RESULTS: Total 43 patients who were referred for ablation therapy for AVNRT, RSAP and LSAP were involved in the result analysis without loss. Plasma NGF increased at 6 hours after RFCA. Increased NGF continued to 7 days in the RFCA treated patients. The plasma NGF concentrations at 6 hours, 1, 3, 5, 7 days after RFCA in AVNRT, RSAP and LSAP ablations treated patients were (29.72±7.04), (30.94±5.68),(31.39 ±4.92), (31.06 ±4.56), (29.11 ±4.59), (31.77 ±6.25), (30.69 ±5.10),(31.46±4.96), (30.15±4.01), (30.43±3.14), (31.42±6.75), (31.00±5.20),(32.08±4.62), (30.67±3.71), (29.27±2.75) μg/L, respectively, and all more than that before RFCA [(14.89±2.84), (15.00±2.71), (15.51±2.75) μg/L, P ＜ 0.01]. However, there were no significant differences in the NGF levels at 6 hours, 1, 3, 5 and 7 days after RFCA (P ＞ 0.05). The plasma NGF concentration was not significant different among AVNRT, RSAP and LSAP ablation patients at any given time (P ＞ 0.05). The number of RFCA applications, the procedure time and the total energy have no correlation with NGF concentration at any given time instance.CONCLUSION: RFCA increases plasma NGF concentration in humans and lasts for at least 7 days. The number of RFCA applications, the procedure time and the total energy have no correlation with NGF concentration at any given time instance.

Objective To study the possible different effects on primary liver cancer of various types of blood supply demonstrated by DSA via hepatic artery radioimmunotherapy with 131Ⅰ-HAb18F(ab')2.Methods Under thyroid protection and negative dermal sensitivity test,46 times of intraarterial injection with a 0.75 mCi/kg dose of 131Ⅰ labeled murine HCC monoclonal antibody fragment [HAb18F(ab')2] were performed in 30 patients of PLC using the Seldinger technique.The shrinkage rates of tumor volume were analyzed according to hyper,moderate and hypo vascular three types provided by DSA.Results The volume shrinkage rates of hyper and moderate vascular HCC were 60% and 37.5% respectively,while that of 2 cases of hypovascular HCC showed significantly reduction.Conclusion 131Ⅰ-HAb18F(ab')2 internal radioimmunotherapy prossesses certain signification volume shrinkage efficacy on different blood supplies provided by DSA.(J Intervent Radiol,2007,16:243-245)

Objective To analyze the clinical effects of 131I-HAb18F(ab')2 radioimmunotherapy via hepatic artery on PLC with portal vein tumor emboli. Methods Under the condition of thyroid protection and negative dermal sensitivity test, 12 times of intraarterial injection with 131I labeled murine HCC monoclonal antibody fragment HAb18F(ab')2 were performed in 8 patients of PLC complicated with portal vein tumor emboli. A 0.75 mCi/kg dose of 131I was administrated individually into certain target vessel after hepatic artery angiography using Seldinger technique. Results 3 of 7 patients with symptoms of pains showed remission with simultaneous improvement and stabilization in Karnofsky score in 3 and 4 patients respectively. AFP levels decreased about 50%(3/6)in 3 cases among those 6 positives and the values of I.B. and ALT changed within a very narrow range to a certain extent after the treatment. The overall rate of CR + PR was 28.6% and similar better result was obtained in a non-symptomatic diffuse PLC patient.1 year survival rate was 12.5%. Conclusion 131I-HAb18F(ab')2 radioimmunotreating drug(0.75 mCi/kg)with hypotoxicity to liver-function can be used as an acceptable method for unresectable PLC with portal vein tumor emboli, especially for those without tumor emboli in the main trunk.

Objective To evaluate the risk factors associated with in-hospital death in patients co-infected with human immunodeficiency virus and Mycobacterium tuberculosis (HIV-TB). Methods A retrospective case-control study was performed in patients admitted to Shanghai Public Health Clinical Center from November 2004 to May 2009. Fifty-three HIV-TB patients who died during hospitalization were matched with 79 HIV-TB co-infected patients who survived during hospitalization.Clinical, demographic, and radiological characteristics of the two groups were compared by the retrospective case-control study method. Multivariate Logistic stepwise regression analysis was performed to explore the risk factors contributing to death in HIV-TB co-infected patients. Results Among the 459 co-infected patients, 53 (11.5%) cases died during hospitalization and 25 cases died during the first week in hospital. Sixty-four point two percent dead patients (34/53) died from tuberculosis. Several factors were associated with worse prognosis in the death group compared to the survival group, which included body weight≤50 kg (χ2 = 7.50), positive for acid-fast bacilli in sputum smear or culture exam (χ2= 4. 04, 14. 27), drug-resistant/multi-drug resistant Mycobacterium tuberculosis infection (χ2 =9.00,6.39), extra-pulmonary tuberculosis infection (χ2 =6.99), retreated tuberculosis (χ2 = 5. 92), non-standardized anti-tuberculosis treatment (χ2 = 12. 07), extensive pulmonary TB infection (lesions ≥50% of lung fields, χ2 = 20. 21), co-infection with fungi (χ2 =3.46), respiratory failure (χ2 = 4.27), non-pulmonary organ impairment (χ2 = 3.46), HIV infection longer than 5 years (χ2 = 7. 19), non-standardized highly active antiretroviral therary treatment (χ2 =5.16) and CD4+ T lymphocyte count ≤ 200 × 106/L (χ2= 12.99) (all P＜0. 05). Multivariate Logistic regression analysis showed that non-standardized anti-TB treatment, extensive pulmonary TB infection, multi-drug resistant TB infection and CD4+ T lymphocyte count ≤ 200 × 106/L were the major risk factors related to in-hospital mortality. Conclusions Non-standardized anti-TB treatment,extensive pulmonary TB infection, multi-drug resistant TB infection and CD4+ T lymphocyte count ≤200 × 106/L are the major risk factors related to in-hospital mortality in the patients co-infected with TB and HIV.
