Objective

2

To explore the effect of Suanzaoren Tang combined with Ziwu Liuzhu acupuncture on the vertebral artery hemodynamics， inflammatory cytokines， and neurotrophic factors in the patients with cervical insomnia with syndrome of deficiency of both heart and spleen.

Method

2

The random number table method was employed to assign 164 patients with cervical insomnia with syndrome of deficiency of both heart and spleen treated in the First Clinical Medical School of Guangzhou University of Chinese Medicine from January 2018 to June 2021 into a control group and an observation group. The control group was orally administrated with 1-2 mg estazolam tablets before bed for 4 weeks， and the observation group with Suanzaoren Tang combined with Ziwu Liuzhu acupuncture for 4 weeks. The therapeutic efficacy and safety were observed. The Pittsburgh Sleep Quality Index （PSQI） score， polysomnography monitoring results， hemodynamics parameters of vertebral artery， and serum levels of inflammatory cytokines and neurotrophic factors were compared before and after treatment.

Result

Except 4 dropouts， the remaining 160 patients were included in this study， with 80 patients in each group. The observation group had higher total effective rate than the control group ［92.50% （74/80）

Conclusion

2

Ziwu Liuzhu acupuncture combined with Suanzaoren Tang can improve blood circulation of vertebral artery， reduce the serum levels of inflammatory cytokine， and increase the serum levels of neurotrophic factors to improve the sleep quality of the patients with cervical insomnia with syndrome of deficiency of both heart and spleen.
