摘　　要：目的从下丘脑结节状乳头体核(TMN)雌激素受体和食欲素A(OXA)表达的角度探究更欣汤治疗围绝经期失眠的可能作用机制。方法选取动情周期规律的雌性ICR小鼠,应用4-乙烯基环己烯二环氧化物(VCD)联合对氯苯丙氨酸(PCPA)混悬液腹腔注射建立围绝经期失眠小鼠模型。造模成功的75只小鼠随机分为模型组、佐必克隆组及更欣汤低、中、高剂量组,每组15只,另设正常小鼠15只为空白组。造模成功后次日,更欣汤低、中、高剂量组小鼠每日9:00分别给予更新汤颗粒1.15、2.3、4.6 g·kg^(-1)·d^(-1)灌胃,佐匹克隆组小鼠同时间点给予佐匹克隆混悬液1.13 mg·kg^(-1)·d^(-1)灌胃,空白组、模型组小鼠同时间点予蒸馏水1 ml·kg^(-1)·d^(-1)灌胃,各组均连续14天。实验期间观察各组小鼠日间活动、精神状态、饮食、毛色等一般情况;末次干预24 h后,采用戊巴比妥钠协同试验检测小鼠睡眠潜伏期及睡眠持续期,ELISA法检测小鼠血清雌二醇(E2)、孕酮(P)、促卵泡生成激素(FSH)以及下丘脑TMN区OXA水平,免疫荧光染色法检测小鼠TMN区雌激素受体α(ERα)、OXA、雌激素受体β(ERβ)蛋白光密度值。结果空白组小鼠昼夜节律正常;模型组小鼠昼夜节律紊乱,白天和晚上保持活跃;更欣汤各组小鼠精神状态较前改善,小鼠精神状态明显好转,白天活动较前减少,毛色稍黄、但有光泽,尤以更欣汤中剂量组最明显;佐匹克隆组白天活动较前减少,毛发粗糙少光泽,警觉性高。与空白组比较,模型组小鼠睡眠潜伏期延长,睡眠持续期缩短,血清E2、P水平降低,血清FSH和TMN区OXA蛋白表达增加,TMN区ERα、ERβ光密度值减少,OXA光密度值增加(P<0.05或P<0.01)。与模型组比较,更欣汤低、中、高剂量组和佐匹克隆组小鼠睡眠潜伏期缩短,睡眠持续期延长(P<0.01);更欣汤中、高剂量组血清E2、P水平升高,FSH及TMN区OXA水平降低(P<0.05);更欣汤中剂量组小�Objective To explore the possible mechanism of Gengxin Decoction(更欣汤)in the treatment of perimenopausal insomnia from the perspective of the expression of oestrogen receptor and orexin A(OXA)in hypothalamic tuberomammillary nucleus(TMN).Methods Female ICR mice with regular estrous cycle were selected to estab⁃lish perimenopausal insomnia mice models by injecting 4-vinylcyclohexene diepoxide(VCD)combined with parachlorophenylalanine(PCPA)suspension intraperitoneally.After successful modeling,75 mice models were randomly divided into model group,zopiclone group and low-,middle-,and high-dose Gengxin Decoction,with 15 mice in each group,and 15 normal mice were set as blank group.On the next day after successful modelling,mice in the low-,middle-,and high-dose Gengxin Decoction were given Gengxin Decoction granules 1.15,2.3 and 4.6 g·kg^(-1)·d^(-1) by gavage at 9:00 AM every day,mice in the zopiclone group were given zopiclone suspension 1.13 mg·kg^(-1)·d^(-1) by gavage at the same time point,and mice in the blank and model groups were given distilled water 1 ml·kg^(-1)·d^(-1) by gavage at the same time point,for 14 days in all groups.During the experimental period,general conditions of the mice in each group,such as daytime activities,mental state,diet and coat colour,were observed;twenty-four hours after the final intervention,the sleep latency and sleep duration of mice were detected by sodium pentobarbital synergy test,and the levels of serum estradiol(E2)、progesterone(P)、follicle stimulating hormone(FSH)and OXA protein in TMN of hypothalamus were detected by ELISA,and the protein optical density values of estrogen receptorα(ERα),OXA and ERβin TMN was detected by immunofluorescence staining.Results The circadian rhythm of mice was regular in the blank group;the circadian rhythm of mice was disordered in the model group,and they remained active during the day and night;the mental state of mice in each group of Gengxin Decoction was improved compared with that before,which showed that the dayti
