    Objective. To investigate the expression of annexin A2 (ANXA2) and β-catenin in eutopic and ectopic endometrium, and their relationships with adenomyosis-associated dysmenorrhea. Methods. From December 2013 to June 2014, ectopic endometrium (n=30) and eutopic endometrium (n=30) of adenomyosis were collected as experimental group, and endometrium (n=30) of uterine myoma as control group from the department of gynecology and obstetrics, the affiliated hospital of Inner Mongolia medical university. The expression of ANXA2 and βcatenin was detected by immunohistochemical S-P method, followed by the Pearson correlations for the correlation analysis of ANXA2 and β-catenin with adenomyosis-associated dysmenorrhea. Meanwhile, the levels of preoperative serum ANXA2 of patients with adenomyosis (n=42) and uterine myoma (n=42) were also measured by enzyme-linked immunosorbent assay (ELISA). Results. Immunohistochemistry and ELISA identified a higher expression of ANXA2 in eutopic and ectopic endometrium of adenomysis tissues, whereas βcatenin protein was down-regulated. Furthermore, there was a significant positive correlation between ANXA2 expression and dysmenorrhea degree, while there was a negative linear correlation between β-catenin expression and dysmenorrhea degree in ectopic endometrium. Conclusion. These results suggested that increased ANXA2 and less expressed β-catenin were correlated to adenomyosis-associated dysmenorrhea. It may provide a new idea of diagnosis and treatment to adenomyosisassociated dysmenorrhea.

    Increased endometrial expression of CC-chemokine receptor-1 in women with adenomyosis

    Abnormal endometrial expression of CCchemokine receptor-1 (CCR1) may play a role in the pathogenesis of endometriosis. Adenomyosis, also called endometriosis interna, occurs when the endometrium invades the myometrium. The objective of this study was to determine CCR1 expression in endometrium in women with adenomyosis as compared to women without adenomyosis. We evaluated endometrial mRNA and protein expression in women with and without adenomyosis using quantitative polymerase chain reaction (PCR), immunohistochemical staining and western blot analysis, respectively. We detected CCR1- immunoreactive expression in endometrium in all women with and without adenomyosis. CCR1- immunoreactive staining in endometrial cells was significantly higher in women with adenomyosis (4.89±1.06) compared to those without adenomyosis (2.21±1.16, P<0.001). Women with adenomyosis had higher levels of CCR1 mRNA in endometrium compared to women without adenomyosis (P<0.05). CCR1 protein levels in endometrium were significantly higher in women with adenomyosis (1.66±0.79) compared to women without adenomyosis (0.56±0.13, P<0.001), and positively correlated with the severity of dysmenorrhea (r=0.87, P<0.001). These results suggest that increased CC-chemokine receptor expression may play a role in the pathogenesis of adenomyosis.
