乳房聚丙烯酰胺水凝胶取出术的手术配合

对81例患者行乳房内聚丙烯酰胺水凝胶（PAHG）取出术。结果手术均获成功，手术时间1．5～5．5h，平均2．6h。术中出血量90～1080ml，平均645．0ml。住院时间7～15d，平均8．9d。无血肿、感染等并发症，MRI复查PAHG清除率均达95．0％。提出术前加强心理护理并完善术前准备，术中密切监测生命体征和出入量，及时补充血容量，保证手术野照明，充分灌洗手术腔隙，减少PAHG在体内残留等措施是保证手术成功的重要环节。     

Synthesis and Purine P2X Receptor Antagonist Activity of Thiazole Derivatives

The ability of 12 new thiazole derivatives to influence the muscle contractility mediated by purine P2X receptors has been studied in vitro using isolated tissues of rats and guinea pigs. Most of the synthesized compounds did not cause significant effects, but two compounds exhibited pronounced antagonism with respect to P2X-mediated contractility response. These compounds offer a good starting point for the synthesis of new effective antagonists of P2 receptors. __________ Translated from Khimiko-Farmatsevticheskii Zhurnal, Vol. 39, No. 6, pp. 22 – 25, June, 2005.     

Effect of kanamycin on the cochleas in guinea pigs

Kanamycin (400 mg/kg) was injected daily for 5 days in guinea pigs, the changes in CM and AP responses were recorded. The CM threshold was elevated in 34.5% of the animals and the CM amplitude was reduced when compared with normal animals (P less than 0.005). The AP threshold was elevated in 13.8%. The latency of N1 was increased (P less than 0.001) and the amplitude of N1 reduced at 80 dB (S-L) (P less than 0.001).cAMP and cGMP levels in the organ of Corti and stria vascularis spiral ligament decreased, and the decrease correlated with the changes in auditory function. We consider the reduction of cyclic nucleotides in the cochlea may be important in kanamycin ototoxicity.     

被美术馆环绕的工厂

2005年4月中旬，应EIZO Nanao Corporation的邀请，我们来到日本对EIZO公司进行了参观访问。以为只是一个例行公务的采访，没想到的是，几天的行程下来，又因为几座美术馆，而让我对EIZO有了新的看法，并且有了意外的收获。     

腹腔镜肝切除术患者的护理

笔者报道腹腔镜肝切除术患者的护理。术前进行心理护理和呼吸训练；术后注意早期活动，加强腹腔镜CO2气腹后的观察、护理，做好皮下气肿、胆漏、出血、高碳酸血症和下肢静脉血栓等术后并发症的观察及护理。认为周到细致的护理是手术成功的重要保证。     

垂体后叶素联用普鲁卡因治疗肺结核大咯血25例临床观察

目的 探讨垂体后叶素与普鲁卡因联用治疗肺结核大咯血的效果.方法 回顾性分析我院2003～2007年应用垂体后叶素与普鲁卡因联用治疗肺结核病大咯血25例(治疗组)的临床资料,并与同期随机选取垂体后叶素治疗的20例(对照组)对比.结果 治疗组总有效率为92%,对照组总有效率为70%,治疗组副反应发生率为12%,对照组副反应发生率为45%.结论 垂体后叶素与普鲁卡因联用治疗肺结核大咯血安全有效.     

氢氟酸烧伤的护理

目的探讨氢氟酸烧伤的早期护理措施。方法对18例氢氟酸烧伤患者进行早期护理观察,配合医生实施相应的抢救治疗措施。结果患者伤后早期应用流动冷水冲洗及相应的急救措施可有效的缓解疼痛症状。18例患者全部治愈。结论在早期积极实施抢救措施的同时,加强对患者全面细致的观察,有助于早期发现病情和进行相应的治疗护理。
