Effects of Hewei Anshe Formula (和胃安神方) on the CLOCK and BMAL1 Gene Expression of Hypothalamic Biological Clock in Insomnia Rat Models
Sixty male SD rats were randomly divided into the normal group, the model group, the eszop
iclone group and the low-, medium- and high-dose
Hewei Anshen Formula
groups. The insomnia model was constructed by intraperitoneal injection of p-chlorophenylalanine (PCPA) for 2 days in all groups except the normal group. After successful modelling, the eszopiclone group was given 0.33 mg/(kg·d) eszopiclone aqueous solution by gavage, the low-, medium- and high-dose
Hewei Anshen Formula
groups were given 10 ml/kg of
Hewei Anshen Formula
with a concentration of 1, 2 and 4 g/ml, respectively, and the rats in the normal group and the model group were given 10 ml/kg of saline by gavage, once a day for 7 consecutive days. The general condition of the rats was observed during the experiment, and the body mass of the rats was measured every day after medication administration. The following day after the last medication administration, pentobarbital sodium co-test was used to observe the sleep condition, and the sleep latency and sleep duration were recorded; immunohistochemistry and Western blot were used to detect the expression of hypothalamic clock rhythm regulating protein (CLOCK) and brain and muscle aromatic hydrocarbon receptor nuclear transporter-like protein 1 (BMAL1) in the rats.
Results
2
The body mass of rats in the model group was lower than that of rats in the normal group at all time points (
P
<0.01); compared with the same time in the eszopiclone group, the body mass of rats in the low-dose
Hewei Anshen Formula
group was elevated on the 5th, 6th and 7th days of medication administration (
P
<0.05). Compared with the normal group, the sleep duration of rats in the model group was shortened (
P
<0.01); compared with the model group, the sleep duration of rats in each dosage group increased (
P
<0.01), and the difference between the high-dose
Hewei Anshen Formula
group and the eszopiclone group showed no statistically significant (
P
>0.05), while the sleep duration of the low- and medium-dose
Hewei Anshen Formula
groups were shorterned than the eszopiclone group (
P
<0.01). The difference in sleep latency showed no statistically significant among each group (
P
>0.05). The results of both immunohistochemistry and Western blotting showed that the expression of CLOCK and BMAL1 in the hypothalamus of rats in the model group was significantly reduced compared with that in the normal group (
P
<0.01); the expression of CLOCK and BMAL1 in the hypothalamus of rats in the low- and high-dose
Hewei Anshen Formula
groups increased than that in the model group (
P
<0.05 or
P
<0.01).
Conclusion
2
Hewei Anshen Formula
can improve insomnia in model rats, and its mechanism of action may be related to the up-regulation of the expression of the hypothalamic biological clock genes CLOCK and BMAL1 protein.
