    Histopathological characteristics of adenomyosis: structure and microstructure
    (Universidad de Murcia. Departamento de Biología Celular e Histología, 2023) Liu, Ziyu; Guo, Yanxian; Pan, Xinyi; Yang, Xing
    Adenomyosis is a benign uterine disease that pathologically shows endometrial glands and stroma in the myometrium. There are multiple lines of evidence that adenomyosis is associated with abnormal bleeding, painful menstruation, chronic pelvic pain, infertility, and spontaneous pregnancy loss. Pathologists have researched adenomyosis by studying tissue specimens from its first report more than 150 years ago, and differing viewpoints on its pathological alterations have been advanced. However, the gold standard histopathological definition of adenomyosis remains controversial to date. The diagnostic accuracy of adenomyosis has steadily increased due to the continual identification of unique molecular markers. This article provides a brief description of the pathological aspects of adenomyosis and discusses adenomyosis categorization based on histology. The clinical findings of uncommon adenomyosis are also presented to offer a thorough and detailed pathological profile. Furthermore, we describe the histolog

    Increased annexin A2 and decreased β-catenin in adenomyosis contribute to adenomyosis-associated dysmenorrhea
    (Universidad de Murcia. Departamento de Biología Celular e Histología, 2017) Liu, Li Xue; Wu, Yin Ga; Zheng, Jian
    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
    (F. Hernández y Juan F. Madrid. Universidad de Murcia: Departamento de Biología Celular e Histología, 2014) Xu, Hong; Yang, Yanfeng; Zhou, Caiyun; Huang, Xiufeng; Lin, Jun; Zhang, Xinmei
    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.
