Objective To evaluate the impact of vagal denervation (VD) that is derived from circumferential ablation of pulmonary vein ostium for paroxysmal atrial fibrillation (AF) on the therapeutic results. Methods A total of 50 patients with paroxysmal atrial fibrillation were enrolled in this study. Circumferential ablation of pulmonary vein ostium was carried out in all the patients. The end point of ablation was pulmonary vein electricity isolation. The patients in whom VD occurred during the performance of ablation were regarded as VD- positive group (n = 19), and the remaining patients were used as VD- negative group (n = 31). The recurrence rate of AF six months after the treatment was recorded, and the results were compared between the two groups. Results The end point of ablation was successfully achieved in all the fifty cases. Six months after the ablation, the therapeutic effect of VD- positive group was significantly better than that of VD- negative group (84.21% vs 64.51%, P ≤ 0.05). Conclusion The vagal denervation effect that is derived from circumferential ablation of pulmonary vein ostium in treating AF can significantly increase the success rate of radiofrequency ablation for AF.

It is very necessary to apply case-teaching method to Emergency Medicine in Universities of TCM. To establish the case-teaching system,we ourselves have written teaching materials,trained teachers, and designed all sorts of the medical records. Moreover, we have deployed other methods and principles to put this teaching into practice, used clinical skill practising as a essential supplement of teaching effect. Comparing with the traditional teaching method, it is clear that case-teaching method could make students' learning initiative and positivity improved significantly, their test scores promoted obviously. Thus, carrying out case-teaching method in Emergency Medicine could advance students capability of acquisition of knowledge and their clinical thinking .

We retrospectively analyzed the etiology of 26 new-onset pituitary neoplasms, which were diagnosed at outpatient department of internal medicine over the last 2 years.

Objective To investigate the clinical efficacy and safety of ziprasidone mesylate injection on the acute agitation symptom in mental retardation. Methods The total of 80 patients of mental retardation with acute agitation symptoms were randomly divided into two groups:the treatment group (40 patients) were intra-muscarly given with ziprasidone mesylate injection at the initial dose of 10 mg, 20 mg 4 h later, and 30 mg once on the second day and third day. And the control group (40 patients) were treated with haloperidol injection. The volume dose of haloperidol was 20 mg everyday. Other antipsychotic drugs, antimanic drugs and benzodiazepines were not allowed to be used during the observation, neither does the prophylactic use of drugs against parkinson's disease. Before and 1, 2, 4, 6, 8, 12, 24, 48, 72 h after treatment, the positive and negative scale ( PANSS) reduction rate, the end of the clinical global impression scale ( CGI) were assessed. By the end of the treatment, the adverse reactions symptom, cale ( TESS) was assessed for the safety. Results By the end of treatment PANSS reduction rate was 46. 31% in the test group and 48. 81% in the control group, the clinical improvement rate was 80. 00% in the treatment group and 82. 50% in the control group. No statistically significant difference on efficacy was found between two groups. The side reaction rate in the treatment group was 27. 5%, that in the control group was 40. 0%, there was significant difference ( P<0. 05) between two groups, but the extrapyramidal reaction in the control group was significantly more than that in the treatment group(P<0. 05). Conclusion Ziprasidone mesylate injection is effective on treating the symptoms of mental retardation, in corresponding to the effect of haloperidol injection,and with less extrapyramidal reactions.

BACKGROUND:Toxic cytarabine is often used to prepare highly purified neurons in experimental studies addressing central nervous system diseases. However, the intervention time of cytarabine is little reported. OBJECTIVE:To determine the optimal intervention time of cytarabine(final concentration 10μmol/L) in primary culture of rat cortical neurons. METHODS:Rat primary cortical neurons were cultured in Neurobasal+B27 medium, and 10μmol/L cytarabine were added at 12, 24, 36 and 48 hours after culture, respectively. Half of the medium were changed every 48 hours. The morphology of neurons was observed under inverted microscope at 7 days. The purity and differentiation of neurons maturity were identified by immunocytochemistry method of neuron specific enolization enzyme staining. Morphometric analysis for all neuron-specific enolase positive cells was performed by Multifunction Computer Image Analysis System. RESULTS AND CONCLUSION:After addition of cytarabine at 24 hours of culture, the purity of neurons was more than 90%, well-differentiated cortical neurons accounted for 89.00%, and the area of neuronal body was the largest with the longest synapses. There were more neuron cells with transparent cytoplasm, and large nucleus. The cell body had good refraction and strong stereo sense. The neurons with 3-4 synapses and 3-4 bifurcates formed a good network structure. These results illustrate that although it willbe beneficial for the purity of neurons to add cytarabine early in neuron culture process, it will make obvious effect on neuronal differentiation. The highly purified and well-grown cerebral cortical neurons will be obtained after cultured in neurolbasal medium, which cytarabine is added to at 24 hours of culture.
