Decreased expression of chromodomain helicase DNA-binding protein 9 is a novel independent prognostic biomarker for colorectal cancer.

Previous studies suggested that chromodomain helicase DNA-binding proteins (CHDs), including CHD 1-8, were associated with several human diseases and cancers including lymphoma, liver cancer, colorectal cancer, stomach cancer, etc. To date, little research on CHD 9 in human cancers has been reported. In this study, we assessed the prognostic value of CHD 9 in patients with colorectal cancer (CRC).

[Changes of Serum Gonadal Hormones Levels During Musk-secreting Period and Estrus of Moschus berezovskii].

Objective: To detect concentrations of serum gonadal hormones (testosterone, estradiol and progesterone) in musk-secreting period and estrus of Moschus berezovskii, and to study the association of serum gonadal hormones concentrations and musk-secreting.

Methods: The concentrations of serum gonadal hormones were detected with magnetic particle separation ELISA.

Results: During musk-secreting period, concentration changes of three serum gonadal hormones showed clear regularity, three crests occurred synchronously.
