Objective:To explore the molecular mechanism of modified Guizhi Fulingwan in rats with uterine fibroids. Method:Seventy-two female adult SD rats of SPF grade were randomly divided into a model group, a normal group, and a preventive administration group. The model group and preventive administration group were established by estrogen and progestin loading method. After successful modeling, the rats in the model group were randomly divided into a western medicine group (mifepristone), the high-dose traditional Chinese medicine(TCM) group, and a low-dose TCM group. All the rats were dosing as required once a day for 28 consecutive days. Hematoxylin-eosin(HE)staining was used to observe the morphological changes of the uterus. The micRNA gene chip was used to detect the expression profile of uterine micRNA gene. Differential expressions of micRNA were screened by bioinformatics methods. Gene function enrichment was used to predict the possible signaling pathways in rats with uterine fibroids by modified Guizhi Fulingwan. Result:Compared with the normal group, microRNA of the model group was 1 up-regulated and 9 down-regulated. Compared with the model group, microRNA of the high-dose group of TCM group was 2 up-regulated and 1 down-regulated, in the preventive administration group, 9 was up-regulated and 2 was down-regulated. Gene function enrichment analysis indicated that four signaling pathways were closely related to uterine fibroids. They were mitogen-activated protein kinase (MAPK) signaling pathway, Wnt signaling pathway, mammalian rapamycin target protein (mTOR) signaling pathway and vascular endothelial cell growth factor (VEGF) signaling pathway. Conclusion:Modified Guizhi Fulingwan affected the expression profile of micRNA in rat model of uterine fibroids induced by estrogen and progesterone, suggesting that modified Guizhi Fulingwan may involve in a variety of biological processes such as signal transduction and gene regulation in the treatment of uterine fibroids.

Objective To investigate the disparity and factors of self-rated health between male and female elderly so as to provide evidence for narrowing the disparity and promoting health equity. Methods We extracted data from China Health and Retirement Longitudinal Study in 2013. Fairlie decomposition was adopted to analyze the disparity of self-rated health between 3 744 male and female elderly who were 65 and older. Results The male elderly reported a significantly higher ratio of good health than the female elderly(47.1% vs 41.6%, 2=11.74, P<0.001). Fairlie decomposition analysis revealed that lifestyle, income and educational level were significant influencing factor for self-rated health (all P<0.05), which could explain 73.98%, 17.48% and 16.70% of the overall disparity in self-rated health among the elderly. Conclusions There is a disparity between male and female elderly’s self-rated health. The self-rated health of male elderly is better than that of female elderly. It would contribute to the equity of male and female elderly’s health by promoting publicity of health education and advocating healthy lifestyle of female elderly.
