第一类激素作用在靶细胞表面,并不进入细胞内部,而是与细胞膜表面特异的受体结合.这种结合使腺苷酸环化酶激活产生cAMP(一种第二信使),cAMP再去激活细胞内的一些特定系列的酶,从而引起各种生理效应.这是由E.W.Sutherland于1965年提出来的第二信使假说
第二类激素由于是脂溶性的小分子.能直接进入靶细胞,与靶细胞的细胞质中的受体分子结合成"激素-受体复合物",在一定条件下穿过核膜进入核内,与染色质上的一种酸性蛋白质相互作用,促进DNA样板转录相应的mRNA.
mRNA扩散出核膜进入细胞质,导致某种蛋白质(酶)的合成,从而引起这种激素的生理效应.
作者、斯坦福大学医学中心的梅斯勒(AnnaH.Messner)和同事解释,有多个研究曾检查了在扁桃体切除手术前使用类固醇类药的情况,但得到的结果不一。据他们在8月《耳鼻喉、头、颈外科文献》(ArchOtolaryngolHeadNeckSurg2004;130:917-921)上发表的论文说,他们对这种病人进行了一项最大的前瞻性、随机、双盲研究。
共219名9个月至12岁的参试者被随机分为或用地塞米松1mg/kg,最大剂量至50mg(n=106),或用安慰剂(n=113)。在药物组中,62人进行的扁桃体切除术采用的是电烧烙法,44人采用的是锐性分离。安慰剂两种方法分别为56人和57人。术后第一天,类固醇组医生评定的Wong-Baker可视模拟量表上的疼痛分平均为4.4,安慰剂组5.3(p<0.001);前组家长评估的疼痛分(p=0.002)和病儿自己评估的疼痛分((p=0.002))也明显更低。类固醇组有1.2次呕吐发作,安慰剂组2.1次(p=0.02),前组也更快地恢复了正常进食(=0.004)。另外,作者还发现,进行锐性分离的病人使用类固醇受益最大,医生和家长评估的疼痛分显著低于电烧烙组。
“我们的研究结果支持在进行扁桃体手术时以1mg/kg的剂量IV地塞米松”,研究者总结。
