    • 摘要: Background:Corticotropin-releasing hormone(CRH),the major secretagogue of the hypothalamic-pituitary-adrenal(HPA)axis,is intricately intertwined with the clock genes to regulate the circadian rhythm of various body functions.N6-methyladenosine(m^(6)A)RNA methylation is involved in the regulation of circadian rhythm,yet it remains unknown whether CRH expression and m^(6)A modification oscillate with the clock genes in chicken hypothalamus and how the circadian rhythms change under chronic stress.Results:Chronic exposure to corticosterone(CORT)eliminated the diurnal patterns of plasma CORT and melatonin levels in the chicken.The circadian rhythms of clock genes in hippocampus,hypothalamus and pituitary are all disturbed to different extent in CORT-treated chickens.The most striking changes occur in hypothalamus in which the diurnal fluctuation of CRH mRNA is flattened,together with mRNA of other feeding-related neuropeptides.Interestingly,hypothalamic m^(6)A level oscillates in an opposite pattern to CRH mRNA,with lowestm^(6)A level after midnight(ZT18)corresponding to the peak of CRH mRNA before dawn(ZT22).CORT diminished the circadian rhythm of m^(6)A methylation with significantly increased level at night.Further site-specific m^(6)A analysis on 3’UTR of CRH mRNA indicates that higher m^(6)A on 3’UTR of CRH mRNA coincides with lower CRH mRNA at night(ZT18 and ZT22).Conclusions:Our results indicate that chronic stress disrupts the circadian rhythms of CRH expression in hypothalamus,leading to dysfunction of HPA axis in the chicken.RNA m^(6)A modification is involved in the regulation of circadian rhythms in chicken hypothalamus under both basal and chronic stress conditions.

    • 摘要: Objective:In order to explore the neuroendocrine regulation mechanism of acupuncture and moxibustion in the treatment of allergic asthma and to provide theoretical basis for the effect of acupuncture and moxibustion on regulating mind.Methods:Forty SD rats were randomly divided into five groups:blank group,model group,sham-acupuncture group,acupuncture group and moxibustion group.Ovalbumin(OVA)was used to sensitise the rats.Except the blank group,the other groups were established by intraperitoneal injection of ovalbumin(OVA)and atomization excitation.The blank group was injected intraperitoneally and atomized with normal saline instead of OVA.After successful modeling,the rats in blank and the model group have no any treatment;In the sham acupuncture group,non-acupoint tissues were selected for acupuncture treatment every day;Acupuncture group and moxibustion group were treated with acupuncture or moxibustion at selected acupoints.At the end of the experiment,blood samples were collected to determine corticotropin releasing hormone(CRH).Results:After being sensitised by OVA,the symptoms scores of rats were significantly increased.After treatment,the symptoms of each treatment group were significantly reduced.Compared with model group,the CRH in acupuncture and moxibustion groups were significantly reduced(All P<0.01).Compared with the sham acupuncture group,the CRH in acupuncture group were significantly reduced(P<0.05).Conclusion:As a kind of stimulation,acupuncture and moxibustion can regulate the content of CRH in the body by nerve endocrine system.The effect of"regulating mind"of acupuncture and moxibustion plays an important role in the treatment of allergic asthma.

    • 摘要: 目的:观察龟鹿益神颗粒对慢性疲劳大鼠行为学及神经内分泌网络中枢下丘脑-垂体-肾上腺皮质轴(HPA轴)表达的影响,探讨其抗疲劳效果及其作用机制。方法:采用力竭游泳、慢性束缚复合方法构建慢性疲劳大鼠模型。60只雄性SD大鼠随机分为空白组、模型组、苁蓉益肾颗粒组、龟鹿益神颗粒低、中、高剂量组,10只/组。造模结束后,空白组与模型组给予生理盐水灌胃,苁蓉益肾颗粒组给予苁蓉益肾颗粒混悬液灌胃,龟鹿益神颗粒低、中、高剂量组分别给予1.625 g·(kg·d)^(-1)、3.25 g·(kg·d)^(-1)、6.5 g·(kg·d)^(-1)灌胃龟鹿益神颗粒混悬液灌胃,每天1次,连续灌胃14 d。造模过程中观察各组大鼠行为学情况的变化。造模结束后采用RT-PCR法测定下丘脑CRH mRNA表达、ELISA法测定大鼠血清CORT、ACTH、CRH含量。结果:实验组、苁蓉益肾颗粒组大鼠行为学指标有明显的改善(P<0.05),下丘脑室旁核CRH mRNA表达、血清CRH、ACTH、CORT的含量显著降低(P<0.05),龟鹿益神颗粒中、高剂量实验组明显低于苁蓉益肾颗粒组(P<0.05)。结论:龟鹿益神颗粒可以改善慢性疲劳大鼠的疲劳状态,下调慢性应激时紊乱的HPA轴,其抗疲劳作用机制可能与下调紊乱的HPA轴有关。

    • 摘要: AIM To observe the effect of Yinao Jieyu Granules (Curcumae Radix,Schisandrae chinensis Fructus,Gardeniae Fructus,etc.) on rats depression induced by olfactory bulbectomy (OB).METHODS The model rats randomly divided into model group,Fluoxetine Hydrochloride Capsules group,Yinao Jieyu Granules groups (7.29,3.65 and 1.82 g crude drug/kg) went on with their corresponding intragastric administration once per day (the same volume of purified water for the model group) for 2 weeks.The weight,food intake,liquid consumption,open field test,killing test,light/dark transition test and step-down test were checked every week before and after the administration.The blood sample and brain tissue were procured within 2 hours after the final administration.The serum CRH,ACTH and CORT concentration and the content of hippocampal monoamine neurotransmitters 5-HT,DA and NE were tested by ELISA method.RESULTS Compared with the model group,rats of Yinao Jieyu Granules groups (7.29-3.65 g crude drug/kg) displayed a better sucrose consumption improvement (P < 0.05);more content increase of hippocampal tissue 5-HT (P < 0.05);longer duration time in the dark and on the platform before the error making (P < 0.05);less horizontal and vertical movement,and more significant content decrease of the serum CRH (P < 0.05).CONCLUSION Yinao Jieyu Granules can relieve the depression behaviors of OB animals,and the mechanism may associate with its efficacy on 5-HT and CRH modulation.%目的 采用抗嗅球损毁抑郁大鼠模型(olfactory bulbectomy,OB)方法 观察颐脑解郁颗粒(郁金、五味子、栀子等)对抑郁症的治疗作用.方法 将大鼠随机分为模型组,盐酸氟西汀胶囊组,颐脑解郁颗粒7.29、3.65、1.82 g生药/kg组,灌胃给药1次/d(模型组给予等量纯化水),连续2周.给药前及给药后每周检测体质量、摄食量,进行液体消耗实验、敞箱实验、残杀实验、避暗被动回避、跳台被动回避.末次给药后2h取血样及脑组织,采用ELISA法检测血清促肾上腺皮质激素(ACTH)、皮质醇(CORT)、促肾上腺皮质激素释放激素(CRH)质量浓度,以及海马单胺类神经递质5-羟色氨(5-HT)、去甲肾上腺素(NE)、多巴胺(DA)含有量.结果 与模型组比较,颐脑解郁颗粒(7.29~3.65 g生药/kg)能明显增加嗅球损毁抑郁大鼠糖水消耗量(P<0.05),明显增加海马组织5-HT含有量(P<O.05),明显延长大鼠避暗犯错误潜伏期和跳台犯错误潜伏期(P<0.05),明显减少大鼠水平、垂直运动次数和跳台被动回避试验错误次数(P<0.05),明显降低血清CRH浓度、降低残杀评分(P<0.05).结论 颐脑解郁颗粒有抗嗅球损毁致抑郁作用,其机制可能与调节5-HT、CRH有关.
