Danggui Buxue Decoction (DBD), a famous traditional Chinese medicine (TCM), is often used to treat anemia in China. However, its underlying therapeutic mechanism is unclear. Through the analysis of body weight, spleen and thymus indexes, peripheral blood routine and pathological section of femur, it was obviously that DBD could significantly improve acetylphenylhydrazine (APH) + cyclophosphamide (CTX) induced anemia mice in the present work. Ultra high performance liquid chromatography coupled with quadrupole - Exactive mass spectrometry (UHPLC Q-Exactive MS) based metabolomics and lipidomics was further utilized to screen out differential spleen metabolites associated with DBD treatment. A total of 26 differential metabolites including 8 polar metabolites and 18 lipids were firstly obtained to relate with anemia mice. 7 polar metabolites and 10 lipids among them were reversed by DBD, which the regulation of pyrimidine metabolism and glycerophospholipid metabolism were mainly associated to the anti-anemia effect of DBD based on MetaboAnalyst analysis. Through random forest analysis (RF), ROC analysis and pearson matrix correlation, three metabolites, cytosine, uracil and PC (o-161(9Z)/200), were further screened out as the potential pharmacodynamic biomarkers associated with the efficacy of DBD. This study provided a methodological reference for the study of the mechanism of TCM. The incidence of colorectal cancer (CRC) is increasing annually worldwide. However, traditional chemotherapy has obvious side effects. Low-dose naltrexone (LDN) has been reported to delay tumor progression, but the mechanism remains unclear. Therefore, the aim of this study was to explore the mechanisms underlying the inhibitory effect of LDN on CRC progression in vivo and in vitro. We found that expression of macrophage markers (F4/80, CD68) was increased in nude mice treated with LDN compared with the control group (p  less then  0.05). Additionally, levels of M1 macrophage phenotypic markers (CD80) and cytokines (tumor necrosis factor-α, TNF-α) were higher than in the control group (p  less then  0.05). LDN was able to upregulate expression of the opioid growth factor receptor (OGFr) and apoptosis-related factors Bax, caspase-9, caspase-3, and PARP and downregulate expression of Bcl-2, Survivin, and Ki67 to promote tumor cell apoptosis. Therefore, we speculate that LDN reduces tumor size by increasing levels of M1-like macrophages and activating the Bax/Bcl-2/caspase-3/PARP signaling pathway to induce apoptosis. We suggest that LDN has potential for the treatment of CRC. V.Longitudinal research into the development of prosociality during childhood contributes to our understanding of individual differences in social and emotional outcomes. There is a dearth of literature on the development of prosociality in children with Developmental Language Disorder (DLD). Data from the UK based Millennium Cohort Study was used to investigate prosociality from age 5 to 11 years in 738 children at risk of Developmental Language Disorder (r-DLD) and 12,972 children in a general population (GP) comparison group. Multilevel mixed effects regression models were run to investigate the mean change in prosociality and latent class growth analysis was used to identify heterogeneous groups of children who shared similar patterns of development. selleckchem Overall, children at risk of DLD were less prosocial at age 5 and, although they did become more prosocial by the age of 11, they did not reach the same levels of prosociality as those in the GP group. Subsequent sub group analysis revealed four distinct developmental trajectories stable high (19 %), stable slightly low (36 %), decreasing to slightly low (5 %), and increasing to high (40 %). Children at risk of DLD were less likely than those in the GP group to be in the stable high class and more likely to be in the stable slightly low class. For children at risk of DLD, being prosocial was prot
