Hsa_circ_0000423 promotes colorectal cancer EMT and immune escape by competitive adsorption of miR-369-3p mediating CCND1 expression.

Background: This investigation evaluated the mechanism of hsa_circ_0000423 in colorectal cancer (CRC).

Methods: The hsa_circ_0000423 gene was identified by bioinformatics analyses of GEO circRNA microarrays, and its expression in CRC was investigated. Based on this, in vitro experiments were conducted.

[Study on the biology of adults parasite of Cordyceps sinensis, Hepialus biruensis].

Objective: To supply the basis of the breeding the host of parasite of Cordyceps sinensis for it's natural culturing, by studying the biology of the host of parasite of C. sinensis, Hepialus biruensis.

Method: The host of parasite was collected in field, eclosion, mating and spawning in the different conditions were made, and it's biology and the regularity of the growth and development were observed.
