Effects of Evodia rutaecarpa Acupoint Sticking Therapy on Rats with Insomnia Induced by Para-Chlorophenylalanine in 5-HT1Aand 5-HT2A Gene Expressions
Abstract The main feature of insomnia is difficulty in starting or maintaining sleep. 5-HT1A receptor and 5-HT2A receptor are two subtypes of the classic central 5-HT neurotransmitter closely related to sleep and wakefulness. To observe the effects of Evodia rutaecarpa acupoint sticking therapy on the mRNA expressions of 5-HT1A and 5-HT2A in the hypothalamus, brainstem, and hippocampus of insomnia rats induced by para-chlorophenylalanine (PCPA). Ten rats were randomly selected as the normal group, and 80 PCPA insomnia model rats were randomly divided into eight groups, including a model group, a positive control group (diazepam group), a low-dose E. rutaecarpa acupoint sticking therapy group (Yongquan acupoint group and Shenque acupoint group; the same applied below), a middle-dose E. rutaecarpa acupoint sticking therapy group, and a high-dose E. rutaecarpa acupoint sticking therapy group. The normal group and the model group did not receive treatment. The positive control group was given diazepam through intragastric administration, and the three-dose E. rutaecarpa acupoint sticking therapy groups were divided into the Yongquan acupoint group and the Shenque acupoint group. After seven days of administration, the rat hypothalamus, brainstem, and hippocampus tissues were taken, and a real-time polymerase chain reaction method was used to detect the mRNA expressions of 5-HT1A and 5-HT2A. E.rutaecarpa acupoint sticking therapy significantly upregulated 5-HT1A mRNA expression and downregulated 5-HT2A mRNA expression in rats with insomnia caused by PCPA. No significant differences were found in the expression between the two acupoints and the expression among the three brain tissues. E. rutaecarpa acupoint sticking therapy can improve insomnia. The mechanism may be related to the upregulation of 5-HT1A mRNA expression and the downregulation of 5-HT2A mRNA expression in brain tissue.
