2、-HT2AR)的影響。方法將60只圍絕經(jīng)期大鼠按體重隨機分為5組,每組12只:圍絕經(jīng)期正常對照組(A);圍絕經(jīng)期抑郁癥睡眠障礙模型組(B);圍絕經(jīng)期抑郁癥睡眠障礙補佳樂治療組(C);圍絕經(jīng)期抑郁癥睡眠障礙米氮平治療組(D);圍絕經(jīng)期抑郁癥睡眠障礙中藥治療組(E);A組為圍絕經(jīng)期正常大鼠,其余4組進行18天不可預(yù)知慢性應(yīng)激。于應(yīng)激后對造模動物進行72小時連續(xù)快速眼相睡眠剝奪(REM)。每天在應(yīng)激前1小時按組給藥。在末次灌胃24小時后,頸椎脫臼法處死大鼠,取大鼠海馬,分別用熒光定量檢測海馬5-HT1ARmRNA
3、和5-HT2ARmRNA、蛋白印跡和免疫熒光檢測海馬5-HT1AR和5-HT2AR的表達。結(jié)果蛋白印跡檢測(westernblot)海馬及免疫熒光檢測海馬CA1區(qū)均顯示:海馬區(qū)5-HT1AR表達水平各組無明顯差異(P>0.05),而5-HT2AR表達水平上,模型組顯著低于正常組(P<0.05),治療組提高了5-HT2AR的表達水平,且與模型組相比存在顯著性差異(P<0.05);RT—PCR顯示:海馬區(qū)5-HT1ARmRNA水平各組無明顯差異(P>0.05),而5-HT2ARmRNA水平,模型組明顯低于正常組
4、(P<0.01),米氮平組較模型組有極顯著性差異(P<0.001),中藥組較模型組有顯著性差異(P<0.05)。結(jié)論補腎調(diào)肝清心方能提高5-HT2AR的mRNA及蛋白水平的表達,免疫熒光的結(jié)果表明在海馬CA1區(qū)發(fā)揮作用,表明補腎調(diào)肝清心方可以通過調(diào)節(jié)海馬CA1區(qū)5-HT2AR表達來改善睡眠障礙?!娟P(guān)鍵詞】圍絕經(jīng)期抑郁癥睡眠障礙;補腎調(diào)肝清心方;5-羥色胺1A受體;5-羥色胺2A受體【中圖分類號】R285.5【文獻標識碼】Adoi:10.3969/j.issn.1674—1749.2014.06.003Efe
