简介:【摘要】:痛经,为妇科常见病。本病通常在经行前后发作,表现为下腹部的坠痛、腰酸,甚者出现疼痛发射至大腿内侧、痉挛、呕吐、昏厥。严重影响女性正常的生活工作学习。痛经在临床上可分为原发性和继发性,本篇主要阐述原发性。现代医学的治疗方法多为止痛药物类治疗,具有依赖性,停药后常常出现复发,且存在着副作用。导师金影副教授结合多年临床经验,将此病的致病重点归据与瘀,治疗原则重点也在于化瘀,往往效果甚佳。今取验案1例,供广大专业从事者分享借鉴。

简介:目的:基于重组流感病毒载体的呼吸道合胞病毒(RSV)疫苗的构建及在小鼠体内的免疫保护效果评价。方法:构建并拯救表达RSV A2型G蛋白胞外结构域(Gecto)的重组甲型流感病毒,将其命名为PR8NAGecto/WSN。体外验证重组病毒G蛋白表达与病毒生长动力学后,单剂滴鼻免疫BALB/c小鼠,并评价体液免疫、黏膜免疫与细胞免疫。免疫4周后,分别用RSV A2与RSV B9320进行攻毒,通过小鼠体重变化、肺组织病毒滴度及病理评价免疫保护效果。结果:单剂滴鼻免疫PR8NAGecto/WSN能在小鼠体内产生较强的体液免疫、黏膜免疫及细胞免疫。与对照组比较,免疫组小鼠经RSV A2或B9320两个亚型病毒攻毒后肺病毒载量与肺组织病理均明显改善。结论:单剂滴鼻免疫重组PR8NAGecto/WSN疫苗可在小鼠体内诱导较强的RSV特异免疫应答与攻毒保护。本研究为新型RSV黏膜疫...
