Regulation of miR-30b in cancer development, apoptosis, and drug resistance.

miR-30b, which is encoded by the gene located on chromosome 8q24.22, plays an important role in a variety of diseases. In most types of tumors, miR-30b significantly inhibits the proliferation, migration, and invasion of cancer cells through the regulation of target genes.

[Study of the property of lipids reducing of curcumin on hyperlipidemia mice after fermented by Monascus purureus].

Objective: To study the lipids reducing property of curcumin on Hyperlipidemia mice after fermented by Monascus purureus.

Methods: The stain Monascus purureus was used for microbial transformation, and both substrate control and strain control were set. The mice were reared with high lipid and cholesterol feed for 15d to establish the Hyperlipidemia models.

[Study on endophyte and the growth stages of Ophiopogon japonicus].

Objective: To study on the relationship between the endophyte and the life cycle of Ophiopogon japonicus in Zhejiang.

Methods: Sample roots of Ophiopogon japonicus at different growth stages were thoroughly washed and cut into small fragments, then cleared (removing cytoplasmic contents from cells) using hot 10% KOH and stained with acid fuchsin (alternative stain). The hyphae, the arbuscular and the vesicular of endophyte were examined.
