Influence of Specific Acupoint Acupuncture Therapy to Serum Angiogenesis Factor of Obese Mouse Models / 世界科学技术-中医药现代化

This study was aimed to discuss the influence of specific acupoint acupuncture therapy to the serum angiogenesis factor of high fat diet obese mouse models. Mice were randomly divided into the blank control group , acupuncture control group , model control group , and acupuncture treatment group . There were 6 mice in each group . Obese mouse models were induced after 15-week high fat diet . The specific acupoint acupunc-ture therapy was used as an intervention treatment method for 10 days . The enzyme-linked immunosorbent as-say (ELISA) was used in the detection of serum insulin, vascular endothelial growth factor (VEGF), soluble vascular endothelial growth factor receptor , leptin and the level of nitric oxide in mice . The results showed that the serum insulin , nitric oxide and leptin level in the obese mouse models were increased . However , there were no obvious changes on the vascular endothelial growth factor and soluble vascular endothelial growth fac-tor receptor level . The specific acupoint acupuncture therapy can obviously reduce the level of serum nitric ox-ide and leptin, and improve the content of vascular endothelial growth factor in obese mouse models. However, there were no influence on the level of blood glucose and soluble vascular endothelial growth factor receptor . It was concluded that the specific acupoint acupuncture therapy method had preferable antiobesity action . Its mechanism of action may be related to the regulation of angiogenesis .

Isoflavonoids from Ficus benjamina and their inhibitory activity on BACE1.

Examination of an active extract of the fruit of Ficus benjamina var. nuda (Miq.) Barrett has led to the isolation of six new isoflavones and two coumarano-chroman-4-ones, along with fifteen known compounds. The structures of the eight new compounds were elucidated on the basis of extensive NMR experiments and mass spectrometric measurements. The inhibitory activity of the compounds on the proteolytic cleavage of amyloid precursor protein by the aspartic protease BACE1 was evaluated. Both coumarano-chroma-4-ones and some isoflavones showed moderate activity in this assay.
