ABSTRACT
Ketamine has been used clinically as an analgesic and anesthetic since 1970. Recently, it has been concerned due to its rapid and effective antidepressant effect. However, the psychiatric adverse reactions caused by ketamine such as addiction and hallucination limit its clinical application, yet the mechanism of the adverse reactions is still unclear. At present, it is generally believed that the pharmacological effects of ketamine are mainly mediated by N-methyl-D-aspartate acid (NMDA) receptors, but increasing numbers of research evidences suggest that the opioid receptor also play an important role in the pharmacological effects of ketamine. This review, based on the relevant literature published publicly in the past 20 years, summarizes the mechanisms of opioid receptors in the pharmacological effects of ketamine, such as anesthesia, analgesia, anti-depressant, anti-addiction and addiction, providing reference for revealing the mechanism of ketamine, and making beneficial exploration for solving the clinical side effects of ketamine.
ABSTRACT
Population aging has become a major feature of the demographic structure of today's society， and anti-aging is currently one of the major areas and hot spots of medical research. Kidney deficiency causes aging is the basic theory of aging in TCM， and kidney tonics have a long history of improving physiological functions and significantly alleviating aging-related diseases. However， the formulation of kidney tonics is complicated and the mechanism of action is still unclear. It is difficult to precisely analyze the targets of disease action and metabolic pathways. The kidney tonic herb Epimedium has the effect of tonifying the kidney and augmenting yang， and is not only used to treat diseases related to kidney deficiency and aging， but also has unique advantages in the treatment of mental and emotional diseases. Modern pharmacological studies have proved that Icarrin， a monomeric component of Epimedium， can produce a wide range of biological functions on cardiovascular system， exercise system， reproductive system， and nervous system， with strong antioxidant， free radical scavenging， and repair of mitochondrial DNA damage， which can anti-aging， anti-depression， and improve immunity， etc. In this paper， we searched databases such as CNKI， Pubmed， Wanfang database， Wipu Chinese journal service platform， and web of science to review the research on Icarrin， a monomeric ingredient that has both anti-aging and anti-depression effects， in order to provide a basis for further research on anti-depression and anti-aging in Chinese medicine.

ABSTRACT
Aim: To investigate the effects of Yueju pill on depressive-like behavior and neurogenesis in chronic corticosterone (CORT) induced mice. Methods: Male C57BL/6N mice received chronic administration of CORT as well as Yueju pill. Behavioral tests were performed after the completion of treatment. The number of Ki67+ cells in the hippocampal DG region of each group was counted by immunohistochemistry test. Meanwhile, the expression levels of PKA, ERK and CREB were detected by Western blot. Results: The sucrose preference notably decreased (P < 0. 05) in CORT-induced mice in SPT, and it was raised obviously after Yueju treatment. The TST and NSF test displayed the similar results. The immunohistochemistry showed that the number of Ki67+ cells in the hippocampus DG significantly decreased in CORT-induced mice, while the number of Yueju group apparently increased (P < 0. 05). Western blot showed that compared with control group, the protein expressions of PKA-ERK-CREB pathway were down-regulated in CORT-induced mice, which were up-regulated after Yueju treatment (P < 0. 05). Conclusions: In CORT induced mice, Yueju pill can enhance the hippocampal neurogenesis by activating the PKA-ERK-CREB signaling pathway to display antidepressant-like effect.
