A growing body of evidence has indicated the important role of autophagy receptors in directing ubiquitinated or non-ubiquitinated cargos towards autophagy. Autophagy receptors bind to LC3 (microtubule-associated protein 1 light chain 3) on phagophore and autophagosome membranes, and recognize signals on cargoes in the delivery system of autophagy. However, the diverse domains in the receptor structures determine that their roles would never be limited to autophagy. Up to date, increasing numbers of the receptor proteins have been demonstrated to serve as a molecular link or switch participating in autophagic degradation, apoptosis or cell survival signals. Here, we highlight the non-autophagic roles of these receptor proteins to draw attention to this growing research topic.

Objective To explore the significance of signal and volume change from magnetic resonance imaging (MRI) of hysteromyoma before and after uterine artery embolization (UAE) in the therapy evaluation. Methods MRI was performed in 30 patients (50 hysteromyoma) before and 3,6 and 12 months after UAE. They were grouped by location, signal and size. The MRI signal changes and the hysteromyoma's volume reduction ratio were measured. Results After 3,6,12 months, MRI of hysteromyoma was changed significantly, and all hysteromyomas had lower T2WI signals than before, some of which had higher T1WI signals. Hysteromyoma's volumes were progressively reduced, the majority of which shrinked significantly within 3 months. Evaluated by 12 month's volume changes, significant volume reduction was found in submucous fibroids, and significant difference was showed compared with intramural fibroids and subserosal fibroids (88.9 % vs. 73.7 % and 68.3 %, P=0.036, P=0.019), meanwhile,the latter two had no significant difference (P=0.384). The volume reduction rate in rich cell fibroids was higher than those in ordinary no degeneration fibroids and degeneration type, and there were significant differences (85.7 % vs. 72.1 % and 63.4%, P=0.038, P=0.014). Besides, the latter two had no significant difference (P=0.364). Large fibroids shrinked more obviously than small ones with significant difference (75.2 % vs. 59.6 %, χ2=4.563, P=0.044). Conclusion MRI is useful for the evaluation of efficacy in hysteromyoma before and after UAE, which can provide the better interventional treatment for the patients in regard to different sensitivity of hysteromyoma to UAE.

Objective:To investigate the relationship between FA,ET-1,Hcy and VEGF in patients with pregnancy induced hypertension.Methods:Selected 80 cases of patients with pregnancy induced hypertension who were treated in our hospital from January 2013 to September 2016,divided into A group (40 cases),and preeclampsia and preeclampsia B group (40 cases),60 cases of normal late pregnant women as C group,60 cases of normal non pregnant women as D group.The plasma levels of FA,ET-1,Hcy and VEGF in each group were detected,and the correlation analysis was performed.Results:The plasma levels of FA and VEGF of group B were lowest in the four groups (P＜0.05),the plasma ET-1 and Hcy levels of group B were highest (P＜0.05).The plasma FA and VEGF levels of women with pregnancy induce hypertension were lower than those of the healthy late pregnant women.The plasma ET-1 and Hcy levels were higher (P＜0.05).The multivariate logistic regression analysis showed that FA,ET-1,Hcy and VEGF levels were risk factors for pregnancy induce hypertension.Conclusion:The elevation of plasma Hcy level caused by FA deficiency in pregnancy might be related to the development of the disease and the incidence of pregnancy induced hypertension syndrome,VEGF might be an important factor in the occurrence and development of pregnancy induced hypertension syndrome.
