[Expression of fragile histidine triad in endometriosis].
OBJECTIVE
To detect the expression of fragile histidine triad in endometriosis and investigate the pathogenesis of endometriosis.


METHODS
immunohistochemistry was used to examine the expression of Fhit in the eutopic and ectopic endometria of 58 patients with endometriosis and in the endometria in 15 patients with hysteromyoma.


RESULTS
The intensity of Fhit expression decreased in the order of normal endometrium, eutopic endometrium in endometriosis group, and ectopic endometrium. In patients with endometriosis, Fhit expression in the eutopic and ectopic endometria in proliferative phase showed no significant difference from that in secretory phase (P>0.05). Fhit expression in the ectopic endometrium showed significant difference between different r-AFS stages. MOD of ectopic endometrium in stages I-II was significantly higher than that in stages III-IV (P<0.05), but Fhit expression in the eutopic endometrium showed no significant difference (P>0.05). MOD of ovarian endometriosis showed no difference with that of adenomyosis.


CONCLUSIONS
Fhit may play an important role in the development of endometriosis.
