[Effect of icariin on learning and memory abilities and activity of cholinergic system of senescence-accelerated mice SAMP10].
To investigate the effect of icariin (ICA) on learning and memory abilities and cholinergic system in senescence-accelerated mice SAMP10. ⋯ Different doses of icariin can improve learning and memory abilities of SAMP10 to varying degrees, which may be related to its effect on the cholinergic system.

[Relative expression of genes involved in artemisinin biosynthesis and artemisinin accumulation in different tissues of Artemisia annua].
To study the relative expression of the genes involved in artemisinin biosynthesis in different tissues including roots, stems, leaves and flowers of Artemisia annua, and establish the relationship between gene expression and artemisinin accumulation, eventually leading to discover the mainly effective genes involved in artemisinin biosynthesis. ⋯ In the biosynthesis of artemisinin, the upstream genes including HMGR from the MVA pathway, DXR from the MEP pathway and the checkpoint gene FPS were much more active in flowers, and this suggested that flowers might be the tissues of artemisinin precursor biosynthesis, and further DXR contributed more to artemisinin biosynthesis. The positive correlation of ADS expression and artemisinin content in tissues demonstrated that ADS played a very important role in artemisinin biosynthesis, which was the ideal target for engineering the artemisinin biosynthetic pathway. In summary, the functional genes involved in artemisinin biosynthesis do not express at the same level but synergistically.

[Intestinal absorption effect of Angelica dahurica extract on puerarin of puerariae Lobatae Radix].
To study the effect of extractive Angelica dahutica on intestinal absorption of puerarin, the mechanism of the absorption enhancement of A. dahutica was investigated, providing a new thread of combinations of the Chinese herbal drugs. ⋯ The mechanism of absorption of jejunum was active absorption and was effected by P-gp. The extrative A. dahurica can enhance the absorption of the jejunum.
