[Effect of Erigeron Breviscapus on the expression of OPG/RANKL/RANK in osteoblasts and pre-osteoclasts in vitro].

Objective: To study the effect of Erigeron Breviscapus (EB) at different concentrations and different intervention time points on the mRNA and protein expression of OPG/RANKL/RANK in MG63 osteoblast-like cells and RAW264. 7 pre-osteoclast cells cultured in vitro, thus exploring roles EB played in bone rebuilding and its mechanisms.

Methods: MG63 osteoblast-like cells and RAW264.

[Association of schizophrenia with a promoter polymorphism in the dopamine D2 receptor gene].

Objective: To investigate the association of -141C insert/delete polymorphism with schizophrenia in Wuhan of Hubei province.

Methods: A case-control study was conducted to analyze the polymorphism in the D(2) receptor gene promoter region with schizophrenia. A total of 120 cases of schizophrenia diagnosed according to CCMD-II R criteria and 100 normal controls were recruited in the study.
