Abstract］ objective to evaluate the new effective therapy for refractory chronic prostatitis.methods from february 2001 to february 2005,percutaneous intraprostatic injection with drugs was performed in 1640 cases.results the cure rate and total effective rate of the therapy were 65%(1066/1640),and 100%(1640/1640) for 5 years,respectively.after treatment no obvious complication was found during the follow up for 4 years.conclusion the result suggest that percutaneous intraprostatic injection is a safe and useful therapy for refractory chronic prostatitis.

摘要］ 目的探讨治疗慢性前列腺炎的有效方法。方法对2001年2月～2005年2月1640例慢性前列腺炎患者，行经皮穿刺前列腺注药治疗。结果随访4年治愈率达65%(1066/1640)，有效率达100%(1640/1640)，无明显副作用发生。结论药物直接注射至前列腺内是治疗慢性前列腺炎的一种安全、有效的方法。

Sustained AF could be induced easily in all dogs during vagal nerve stimulation in vivo both before and after isolation of all PVs with encircling lesions created by a bipolar radiofrequency ablation clamp device. PV elimination had no effect on atrial effective refractory period or its responses to cholinergic stimulation. Autonomic ganglia were identified by bradycardic and/or tachycardic responses to high-frequency subthreshold local stimulation. Ablation of the autonomic ganglia overlying all PV ostia suppressed the effective refractory period-abbreviating and AF-promoting effects of cervical vagal stimulation, whereas ablation of only left- or right-sided PV ostial ganglia failed to suppress AF.

无论是在双极环状消融所有PV之前或之后，在体刺激颈迷走神经节过程中持续性房颤在所有犬均能轻易被诱导出，PV切除对心房肌的有效不应期或对胆碱的反应均没有影响，通过对高频的域下刺激发生快速或慢速反应来鉴定自主神经节，消融叠加于PV口部的自主神经节能抑制有效不应期的缩短、和刺激颈迷走神经诱发的房颤促进作用，而仅消融左或右侧PV口部的自主神经节却不能抑制房颤。

Zirconia/graphite compound mold core was prepared by the coating, in which the silicon sol was used as binder and zirconia was used as refractory materials. The application feasibility of metal particles as a coolant in the solidification process was studied, and the application of metal particles as subsidiary coolant in the liquid metal cooling of directional solidification were analyzed and studied in this investigation. The conclusions can be drawn as follows: 1 The zireonia/graphite compound cores fabricated by brushing coating which was prepared by making silicon sol agglutinated zirconia as a refractory material were casteded at 800℃and 1000℃respectively, and the results show that the strength of the mold core is strong enough to meet the requirement of practical casting.
