Stems and leaves of Acanthopanax trifoliatus (L) Merr (AT) are commonly used as an edible vegetable in China. The scientific basis of antioxidant and antiinflammatory activities of AT was investigated. The polyphenol contents and free radical scavenging activities of AT ethanol extracts (EAT) were determined. Chlorogenic acid, isochlorogenic acid A, isochlorogenic acid C, and rutin were identified as major components in EAT. LPS-induced NO production in RAW264.7 cells was decreased significantly (p<0.05) after EAT treatment, compared with controls. In vivo studies indicated that EAT had more activity than chlorogenic acid per mg of dry weight for inhibition of TPA-induced ear edema. TPA-induced increases in cytokine production (TNF-α, IL-6, MMP-9, and TIMP-1) were significantly (p<0.05) reduced by EAT treatment, compared with controls. EAT exerts anti-inflammatory activities probably due, at least in part, to chlorogenic acid.

Female migrants in China: Second child fertility behavior and employment stability
Li Hu,Dong Chenyu,Wang Xiaofeng 이화여자대학교 아시아여성학센터 2022 Asian Journal of Women's Studies(AJWS) Vol.28 No.1
Researchers have found a negative relationship between female fertility and employment. China’s floating population comprises 244 million as of 2017. This migrant population has relevance in view of China’s hukou (household registration) system, with the proportion of females increasing annually. This study is grounded in social role theory and employs the 2016 China Migrants Dynamic Survey (CMDS) to examine the impact of second child fertility behavior on the employment stability of female migrants in China, with respect to urban and rural differences. Binary logistic regression results indicate that bearing second children negatively affects the employment stability of female migrants. Also, its impact is stronger for female migrants of urban origin than their rural counterparts. In addition, family migration is noted to mitigate the conflict between childbearing and employment stability for them as they continue to face the dilemma of having children or seeking employment stability, especially if family and social support is weak or absent. We discuss the implications of this study on policy changes to alleviate the conflict female migrants experience in choosing between fertility and employment.

A simple method for improving surface-enhanced Raman scattering (SERS) performance of aligned silver nanorod (Ag NR) array was investigated. This method was to construct a kind of hybrid substrate by grafting Au@Ag core–shell nanoparticles (NPs) into Ag NR array using poly(2-vinylphridine) (P2VPy) as a bridging agent. The hybrid substrate yielded excellent SERS performance as its detection limit improved from 10 -6 M to 10 -8 M using trans-1,2-bis(4-pyridyl)ethylene (BPE) as probe molecule, which was increased by two orders of magnitude compared with Ag NR array substrate. The significant improvement of SERS performance of Ag NR arrays was attributed to the addition of Au@Ag core–shell NPs. As a result of surface plasmon resonance generated by the interaction of electromagnetic (EM) (IAEM) filed between NP and NR structures, increasing hotspots were found at the connections of NPs and NRs, the gaps of adjacent rods, and the gaps of two particles consequently. These results were validated by the finite difference time domain (FDTD) calculation. Besides, hybrid substrate shows good performance in stability and reproducibility. The proposed method was simple and robust, which promoted SERS performance of Ag NR array effectively, showing great potential in the application of SERS substrate fabrication and SERS-based bio-chemical sensing.
