The intermediate 8 was obtained in a high e.e. value via lipase catalyzed hydrolytic kinetic resolution. Then enantiomerically pure ramosetron hydrochloride was synthesized in two steps with excellent yield (the total yield is 24.6%). The method provides a new environment friendly and atom economy way to synthesize enantiomerically pure ramosetron.展开更多
目的探讨雷莫司琼对腹腔镜胆囊切除手术(laparoscopic cholecystectomy,LC)后恶心、呕吐(postoperative nausea and vomiting,PONV)的预防作用。方法选择90例ASAⅠ~Ⅱ级LC患者,随机分为3组,雷莫司琼0.3mg组(Ⅰ组)、雷莫司琼0.6mg组(Ⅱ...目的探讨雷莫司琼对腹腔镜胆囊切除手术(laparoscopic cholecystectomy,LC)后恶心、呕吐(postoperative nausea and vomiting,PONV)的预防作用。方法选择90例ASAⅠ~Ⅱ级LC患者,随机分为3组,雷莫司琼0.3mg组(Ⅰ组)、雷莫司琼0.6mg组(Ⅱ组)、对照组(Ⅲ组),于手术结束时分别静脉注射雷莫司琼0.3mg、0.6mg和等剂量生理盐水,观察3组患者手术结束后24h内恶心及呕吐的发生情况。结果Ⅰ、Ⅱ组术后24h内恶心、呕吐发生率比Ⅲ组明显降低(P<0.05),Ⅰ、Ⅱ2组之间比较差异无统计学意义(P>0.05),3组之间药物副作用比较差异无统计学意义(P>0.05)。结论雷莫司琼是一种安全、有效、副作用小的止吐药,其临床推荐用量0.3mg即可对LC后PONV起到良好的预防作用。展开更多
