RESUMO
The influence of national health level in the stability and sustainable development of national society is increasingly prominent. The purpose of this study is to examine whether, when, and how national fitness policies exert influence on national health. Panel data from 2008 to 2017 of 30 Chinese provinces (cities) (except the Tibet autonomous region) were used to systematically reveal the direct impact of national fitness policies on national health and its characteristics in different regions, as well as the interaction mechanisms of human capital and finance health expenditures in public sports. This study found that first, national fitness policies had a positive effect on adult health. Second, sports human capital weakens the health effect of national fitness policies, while public finance health expenditures strengthen this effect. Lastly, the health effect of national fitness policies varies significantly across regions due to uneven regional economic development, and the differences in the effects on different age groups (adults and children) are equally pronounced. This study suggests that national fitness public service system and diverse national fitness plans improving national health level are important for a new dynamic balance and high quality coordinated development in both Chinese economic growth and social welfare.

OBJECTIVE: Preeclampsia (PE) affects many women globally and remains a primary cause of neonatal and maternal morbidity and mortality. Aberrant placental microRNA (miRNA) expression might be associated with PE. Previously, 33 PE-related miRNAs, 11 up-regulated and 23 down-regulated, were detected in placentas of women with severe PE when compared with those of normal patients. One of the most up-regulated miRNAs in PE is miR-30a-3p. The predicted target of it is insulin-like growth factor 1 (IGF-1), which has been reported to have a relatively low expression level in PE patients. This study was conducted to determine the aberrant increased of miR-30a-3p in the placentas of women with preeclampsia and to elucidate the target and function of it in trophoblast cells. STUDY DESIGN: miR-30a-3p expression in placenta tissues was compared between women with preeclampsia (n = 25) and normal pregnant women (n = 20). The miRNA target was studied by in silico and functional assay. The effects of the miRNA were verified by apoptosis assay and invasion assay in the trophoblast cell line. RESULTS: miR-30a-3p was increased significantly in the placenta of women with preeclampsia when compared to those with normal pregnancies. Luciferase assay confirmed direct regulation of miR-30a-3p on the expression of IGF-1. Forced expression of miR-30a-3p suppressed IGF-1 protein expression in the HTR-8/SVneo cells. The functional assay suggests that the over-expression of miR-30a-3p alter the invasive capacity of JEG-3 cells and induce the apoptosis of HTR-8/SVneo cells (Figure). CONCLUSION: Expression of miR-30a-3p was significantly increased in the placentas of patients with preeclampsia. miR-30a-3p might be involved in the pathogenesis of preeclampsia by targeting IGF-1 and regulating the invasion and apoptosis of trophoblast cells.
