Investigation on the antidepressant effect of sea buckthorn seed oil through the GC-MS-based metabolomics approach coupled with multivariate analysis.

Depression is one of the prevalent and serious mental disorders and the number of depressed patients has been on the rise globally during the recent decades. Sea buckthorn seed oil from traditional Chinese medicine (TCM) is edible and has been widely used for treatment of different diseases for a long time. However, there are few published reports on the antidepressant effect of sea buckthorn seed oil.

[Anti-depressant effect and mechanism of supercritical CO2 extract from Compound Chaigui Fang].

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time.

Analysis of the restorative effect of Bu-zhong-yi-qi-tang in the spleen-qi deficiency rat model using (1)H-NMR-based metabonomics.

Ethnopharmacological Relevance: Bu-zhong-yi-qi-tang (BT) is a classical formula for the treatment of spleen-qi descending, visceroptosis with hyposplenic qi, uterine prolapse, and rectal prolapse due to chronic diarrhea in traditional Chinese medicine (TCM) and has been identified as an effective drug for the treatment of TCM spleen-qi deficiency in clinical practice. The present study aimed to investigate the restorative effect and the potential mechanisms of Bu-zhong-yi-qi-tang in a rat spleen-qi deficiency model using (1)H-NMR-based metabonomics.

Materials And Methods: The rat spleen-qi deficiency model was established as follows: oral administration of Radix Rhei extract (equivalent to 10g/kg body weight of the crude drug), loaded swimming, and starvation for 24h.

[Effect of lamellar keratoplasty time on the production of serum specific antibody in corneal alkali burns].

Objective: To observe the production of serum specific anti-denatured corneal antibody and the effects of lamellar keratoplasty on changes of corneal histopathology in different stages after alkali burns.

Methods: 20 male New Zealand rabbits, with alkali burns in right eye were randomly divided into 5 groups including: burned group; 2 early lamellar keratoplasty group (operation at 3 or 7 days post alkali burns respectively); 2 middle and later lamellar keratoplasty groups (operation at 2 or 5 weeks after alkali burns respectively). The level of serum specific antibody in each group was detected by ELISA and the corneal structure was evaluated by light and electron microscopy in different stages after alkali burns.
