Objective To investigate the serum sex hormone changes and fertility condition in childbearing age women patients with hyperthyroidism treated by iodine-131 .Methods 50 cases of healthy volunteers were selected .248 childbearing age women pa-tients with hyperthyroidism were divided into the iodine-131 group and the anti-thyroid medication group according to the treatment method .The thyroid function and gonad hormone before treatment and at 6 months after treatment were detected in 3 groups ,and the pregnancy and fetal condition were tracked .Results The change of thyroid stimulation hormone(TSH) level was more sensitive in the iodine-131 treatment group than the anti-thyroid medication group ;luteinizing hormone(LH) ,follicle stimulation hormone (FSH) ,prolactin(PRL) ,testosterone(T) and progesterone(P) before treatment in the two groups were significantly increased com-pared with the control group ,but E2 was decreased ;the changes of sex hormones in the iodine-131 treatment group had differences between before and after treatment ,the changes of T and P in the anti-thyroid medication group were unobvious before and after treatment ;the normal delivery rate in the control group and the iodine-131 therapy group had no statistical difference (χ2 =0 .148 , P=0 .7>0 .05) ,the normal delivery rate in the control group and the anti-thyroid medication group had statistically significant difference(χ2 = 5 .739 ,P=0 .017<0 .05) ,the normal delivery rate in the iodine-131 therapy group and the anti-thyroid medication group had statistically significant difference(χ2 =4 .26 ,P=0 .039<0 .05) .Conclusion The iodine-131 therapy has no influence on the sex hormones and the fertility ability in childbearing age women patients with hyperthyroidism ,and also does not increase the incidence rate of genetic damage .

High expression of Fightless I (FLII) is associated to multiple tumors. Based on our previous study that FLII might be involved in the nuclear export, we assessed the possible interaction of FLII with the nuclear envelop associating proteins Importin β and Nup88. We first constructed GST-FLII, GST-LRR recombinant plasmids and transformed them into the Rosetta strain to produce GST-FLII, GST-LRR fusion protein. After purification of these proteins, GST-pull down, as well as co-immunoprecipitation, were used to test the interaction of FLII with Importin β and Nup88. FLII interacted with Importin β and Nup88, and FLII LRR domain is responsible for these interactions. Thus, FLII may play a role in nuclear export through interaction with Importin β and Nup88.
