The Shenque acupoint is located in the umbilicus of the human body. In the human body meridians, the Shenque acupoint can regulate body functions. The Shenque acupoint was one of the important acupuncture acupoints for the treatment of insomnia. However, the effect of linalool applied at the Shenque acupoint to improve sleep was unknown. This study explored the hypnotic and sedative effects of the main component of lavender, linalool, on the Shenque acupoint of mice and rats. The effects on the sleep latency and sleep duration were studied with the supra-threshold dose of pentobarbital sodium, and the effects on the sleep rate were studied with the sub-threshold dose of pentobarbital sodium. In order to further study the feasibility and superiority of linalool administered at the Shenque acupoint, a pharmacokinetic study was carried out. The pharmacodynamic results showed that the mice and rats treated with linalool at Shenque had the highest sleep rate, the shortest sleep latency, and the longest sleep duration compared with other groups. The T_max and t_1/2 of the LS were longer than those of the LO, and had the characteristics of sustained release. The relative bioavailability of LS was 323.0 ± 31.66%. This showed that the combination of linalool and the Shenque acupoint had greater medicinal effects. This development will provide a new direction for improving sleep.

Background: The progression of liver disease causes metabolic transformation in vivo and thus affects corresponding endogenous small molecular compounds. Metabonomics is a powerful technology which is able to assess global low-molecular-weight endogenous metabolites in a biological system. This review is intended to provide an overview of a metabonomics approach to the drug toxicology of diseases of the liver. Methods: The regulation of, and relationship between, endogenous metabolites and diseases of the liver is discussed in detail. Furthermore, the metabolic pathways involved in drug interventions of liver diseases are reviewed. Evaluation of the protective mechanisms of traditional Chinese medicine in liver diseases using metabonomics is also reviewed. Examples of applications of metabolite profiling concerning biomarker discovery are highlighted. In addition, new developments and future prospects are described. Results: Metabonomics can measure changes in metabolism relating to different stages of liver disease, so metabolic differences can provide a basis for the diagnosis, treatment and prognosis of various diseases. Conclusion: Metabonomics has great advantages in all aspects of the therapy of liver diseases, with good prospects for clinical application.
