Abstract:
Objective To investigate the variation of corticotropin-releasing hormone(CRH)in plasma,the mRNA and protein expression of c-Fos and gap junction gene connexin-43(Cx43)in the myometrium of term pregnancy women,and to study the correlations among CRH,Cx43 and c-Fos at onset of labor.Methods 30 cases in labor(L group),30 cases not in labor(NL group)but in term pregnancy, and 30 cases of non-pregnant(NP group)women undergoing hysterectomy due to cervical intraepithelial neoplasia were recruited into this clinical study.Radioimmunoassay was employed to measure the concentration of CRH in plasma;in situ hybridization assay and streptravidin-biotin peroxidase(SP) immunohistoehemical techniques were respectively used to detect the expression levels of c-Fos mRNA,Cx43 mRNA and the corresponding proteins.Results(1)The concentration of CRH in L group(81.8?11.9) pmol/L was significantly higher than that in NL group(34.5?18.6)pmol/L(P
