The Effect of Dried Ginger (Gan Jiang) on Stomach Energy Metabolism and the Related Mechanism in Rats Based on Metabonomics.

Dried ginger is a commonly used stomachic. Dried ginger is often used as a gastric protector to treat stomach-related diseases. However, the effect of dried ginger on energy metabolism in stomach tissue of rats under physiological condition has not been studied. In this study, different doses of water extract of dried ginger were given to rats for 4 weeks. The activity of Na+ -K+ -ATPase, Ca2+ -Mg2+ -ATPase, SDH (succinate dehydrogenase) enzyme, ATP content, mitochondrial metabolic rate and mitochondrial number in stomach tissue of rats were measured. Analysis of potential biomarkers related to the effect of dried ginger on energy metabolism in stomach tissue of rats by metabonomics, and their metabolic pathways were also analyzed. The results revealed that there was no significant difference in Na+ -K+ -ATPase in high-dose group (GJH), medium-dose group (GJM) and low-dose group (GJL) compared to the Control group. The Ca2+ -Mg2+ -ATPase activity was significantly increased in stomach tissue of GJH group and GJM group, but there were no significant changes in stomach tissue of GJL group. The SDH activity and the ATP levels were significantly increased in stomach tissue of GJH group, GJM group and GJL group. The mitochondrial metabolic rate was significantly increased in GJL group, but there was no significant change in GJM group and was inhibited in GJH group. These effects might be mediated by arginine biosynthesis, glutathione metabolism, arachidonic acid metabolism, glycerophospholipid metabolism, arginine and proline metabolism, purine metabolism pathway.

The first complete chloroplast genome of a traditional Chinese medicinal herb Odontosoria chinensis (Lindsaeaceae).

It is the first report on complete chloroplast genome of Odontosoria chinensis, a traditional Chinese medicinal herb. The genome size is 156,293 bp, containing a pair of inverted repeats (IRs) (25,198 bp) separated by a small single-copy (SSC) region (20,649 bp) and a large single-copy (LSC) region (85,248 bp), respectively. The plastome has 128 genes, including 87 protein-coding genes, 32 tRNA genes, eight rRNA genes, and one pseudogene. The overall GC content is 40.43%. Maximum likelihood tree reveals that O. chinensis is basal lineages of polypods. The study will provide powerful molecular information for further phylogenetic analysis.
