Abstract
The gut microbiota plays a pivotal role in systemic metabolic processes and in particular functions, such as developing and preserving the skeletal muscle system. However, the interplay between gut microbiota/metabolites and the regulation of satellite cell (SC) homeostasis, particularly during aging, remains elusive. We propose that gut microbiota and its metabolites modulate SC physiology and homeostasis throughout skeletal muscle development, regeneration, and aging process. Our investigation reveals that microbial dysbiosis manipulated by either antibiotic treatment or fecal microbiota transplantation from aged to adult mice, leads to the activation of SCs or a significant reduction in the total number. Furthermore, employing multi-omics (e.g., RNA-seq, 16S rRNA gene sequencing, and metabolomics) and bioinformatic analysis, we demonstrate that the reduced butyrate levels, alongside the gut microbial dysbiosis, could be the primary factor contributing to the reduction in the number of SCs and subsequent impairments during skeletal muscle aging. Meanwhile, butyrate supplementation can mitigate the antibiotics-induced SC activation irrespective of gut microbiota, potentially by inhibiting the proliferation and differentiation of SCs/myoblasts. The butyrate effect is likely facilitated through the monocarboxylate transporter 1 (Mct1), a lactate transporter enriched on membranes of SCs and myoblasts. As a result, butyrate could serve as an alternative strategy to enhance SC homeostasis and function during skeletal muscle aging. Our findings shed light on the potential application of microbial metabolites in maintaining SC homeostasis and preventing skeletal muscle aging.

Abstract
The bark and leaves of the Eucommia ulmoides Oliv. (E. ulmoides) have good medicinal value. Studies show endophytes play important roles in host medicinal plant secondary metabolite synthesis, with season being a key influencing factor. Therefore, we used 16 S rRNA to detect endophytic bacteria (EB) in E. ulmoides bark and leaves collected in winter, spring, summer, and autumn, and analyzed the contents of major active components respectively. The results showed that the species diversity and richness of EB of the E. ulmoides bark were higher than those of leaves in all seasons except fall. Among them, the higher species diversity and richness were found in the E. ulmoides bark in winter and spring. EB community structure differed significantly between medicinal tissues and seasons. Concurrently, the bark and leaves of E. ulmoides showed abundant characteristic EB across seasons. For active components, geniposidic acid showed a significant positive correlation with EB diversity and richness, while the opposite was true for aucubin. Additionally, some dominant EB exhibited close correlations with the accumulation of active components. Delftia, enriched in autumn, correlated significantly positively with aucubin. Notably, the impact of the same EB genera on active components differed across medicinal tissues. For example, Sphingomonas, enriched in summer, correlated significantly positively with pinoresinol diglucoside (PDG) in the bark, but with aucubin in the leaves. In summary, EB of E. ulmoides was demonstrated high seasonal dynamics and tissue specificity, with seasonal characteristic EB like Delftia and Sphingomonas correlating with the accumulation of active components in medicinal tissues.

Abstract
Pregnancy is a dynamic state involving rapid physiological changes in metabolism, affecting the health and development of the offspring. During pregnancy, the placenta constitutes a physical and immunological barrier to provide fetal nutrition through the maternal blood and prevent the exposure of the fetus to dangerous signals. Metabolic changes in the plasma, the fecal microbiota profile, and functional regulation in the placenta were studied in sows supplied with a ferrous-sucrose complex (FeSuc) from late gestation to parturition. The results revealed that maternal FeSuc supplementation enhanced arginine and proline metabolism, glutathione metabolism, with increased glutamic acid, beta-D-glucosamine, L-proline, 1-butylamine, and succinic acid and reduced sphingosine and chenodeoxycholic acid sulfate levels in the plasma. Moreover, significantly increased abundances of Christensenellaceae_R-7_group, Prevotellaceae_NK3B31_group, and Lachnospiraceae_NK4B4_group were detected in the feces of sows from the FeSuc group (P < 0.05). Spearman's correlation analysis indicated that Prevotellaceae_NK3B31_group abundances were positively correlated with glutamic acid, indoxyl sulfate, acetyl-DL-leucine, and beta-D-glucosamine, while Christensenellaceae_R-7_group was positively correlated with beta-D-glucosamine. Furthermore, maternal FeSuc supplementation significantly increased neonatal glucose (P < 0.01) and iron (P < 0.01) in the neonatal serum, significantly increased IL-10 and TGF-β1 levels in the neonatal liver (P < 0.01) and jejunum (P < 0.05), promoted the transcription of immune molecules in the placenta, and significantly increased the protein expressions of EGF (P < 0.05), PI3K (P < 0.01), p-PI3K (P < 0.001), p-AKT (P < 0.01), and glucose transporter 1 (GLUT1) (P < 0.001) in the placenta. The current study demonstrated that FeSuc supplementation regulated maternal metabolism processes by altering the fecal microbial composition and improved neonatal immunity and placental glucose transportation by activating the EGF/PI3K/AKT signaling pathways in sows.

Abstract
The objective of this study was to investigate the clinical significance and roles of tumor progression locus 2 (TPL2) and peptidyl-prolyl cis-trans isomerase 1 (Pin1) in the occurrence and development of breast invasive ductal carcinoma (IDC). Immunohistochemistry was used to detect the expression of TPL2 and Pin1 in human breast tissues, which included normal breast tissues (Normal), tissues with fibrocystic changes (FCC), ductal carcinoma in situ (DCIS), and IDC. The roles of TPL2 and Pin1 in the occurrence and development of IDC, as well as the correlation between their expression levels and clinicopathological parameters, were analyzed. Compared with Normal and FCC groups, the overexpression of TPL2 and Pin1 was significantly increased in DCIS and IDC groups (DCIS vs Normal: P = 0.002/P < 0.001; IDC vs Normal: P = 0.007/P = 0.003; DCIS vs. FCC: P = 0.008/P = 0.004; IDC vs. FCC: P = 0.04/P = 0.043). The expression levels of TPL2 and Pin1 were positively correlated in DCIS and IDC groups (P = 0.001, P = 0.011). In the IDC group, the Ki67 level in the TPL2 overexpression group was significantly lower than that in the TPL2 low expression group (P = 0.02). The TPL2 overexpression rate was significantly higher in IDC with histological grades 1-2 than that in IDC with histological grade 3 (P = 0.029). The TPL2 overexpression rate in IDC with tumor-node-metastasis (TNM) stage I was significantly higher than that in IDC with TNM stages II-III (P = 0.035). We conclude that TPL2 and Pin1 may synergistically promote the occurrence and development of IDC, but TPL2 overexpression may be an early molecular event in IDC development. TPL2 overexpression is significantly related with IDC with lower malignancy or earlier TNM stage, suggesting that the prognosis of IDC patients with TPL2 overexpression may be better and TPL2 overexpression may be a predictor of good prognosis in IDC.

Abstract
Skeletal muscle atrophy is a debilitating condition that significantly affects quality of life and often lacks effective treatment options. Muscle atrophy can have various causes, including myogenic, neurogenic, and other factors. Recent investigation has underscored a compelling link between the gut microbiota and skeletal muscle. Discerning the potential differences in the gut microbiota associated with muscle atrophy-related diseases, understanding their influence on disease development, and recognizing their potential as intervention targets are of paramount importance. This review aims to provide a comprehensive overview of the role of the gut microbiota in muscle atrophy-related diseases. We summarize clinical and pre-clinical studies that investigate the potential for gut microbiota modulation to enhance muscle performance and promote disease recovery. Furthermore, we delve into the intricate interplay between the gut microbiota and muscle atrophy-related diseases, drawing from an array of studies. Emerging evidence suggests significant differences in gut microbiota composition in individuals with muscle atrophy-related diseases compared with healthy individuals. It is conceivable that these alterations in the microbiota contribute to the pathogenesis of these disorders through bacterium-related metabolites or inflammatory signals. Additionally, interventions targeting the gut microbiota have demonstrated promising results for mitigating disease progression in animal models, underscoring the therapeutic potential of modulating the gut microbiota in these conditions. By analyzing the available literature, this review sheds light on the involvement of the gut microbiota in muscle atrophy-related diseases. The findings contribute to our understanding of the underlying mechanisms and open avenues for development of novel therapeutic strategies targeting the gut-muscle axis.

Abstract
The gut microbiota acts as a symbiotic microecosystem that plays an indispensable role in the regulation of a number of metabolic processes in the host by secreting secondary metabolites and impacting the physiology and pathophysiology of numerous organs and tissues through the circulatory system. This relationship, referred to as the "gut-X axis", is associated with the development and progression of disorders, including obesity, fatty liver and Parkinson's disease. Given its importance, the gut flora is a vital research area for the understanding and development of the novel therapeutic approaches for multiple disorders. Iron is a common but necessary element required by both mammals and bacteria. As a result, iron metabolism is closely intertwined with the gut microbiota. The host's iron homeostasis affects the composition of the gut microbiota and the interaction between host and gut microbiota through various mechanisms such as nutrient homeostasis, intestinal peaceability, gut immunity, and oxidative stress. Therefore, understanding the relationship between gut microbes and host iron metabolism is not only of enormous significance to host health but also may offer preventative and therapeutic approaches for a number of disorders that impact both parties. In this review, we delve into the connection between the dysregulation of iron metabolism and dysbiosis of gut microbiota, and how it contributes to the onset and progression of metabolic and chronic diseases.

In this study, iron was administered orally and parenterally to anemic piglets to investigate the role of iron in host-microbiota interaction and its effects on intestinal mucosal growth and immune plasticity. We found that oral iron administration easily increased the abundance of Proteobacteria and Escherichia-Shigella, and decreased the abundance of Lactobacillus in the ileum. Furthermore, similar bacterial changes, namely an increase in Proteobacteria, Escherichia-Shigella, and Fusobacterium and a reduction in the Christensenellaceae_R-7_group, were observed in the colon of both iron-supplemented groups. Spearman's correlation analysis indicated that the changed Fusobacterium, Fusobacteria and Proteobacteria in the colon were positively correlated with hemoglobin, colon and spleen iron levels. Nevertheless, it was found that activated mTOR1 signaling, improved villous height and crypt depth in the ileum, enhanced immune communication, and increased protein expression of IL-22 and IL-10 in the colon of both iron-supplemented groups. In conclusion, the benefits of improved host iron outweigh the risks of altered gut microbiota for intestinal mucosal growth and immune regulation in treating iron deficiency anemia.

Abstract
Iron is an important micronutrient that plays a vital role in host defenses and bacterial pathogenicity. As iron treatments increase the risk of infection by stimulating the growth and virulence of bacterial pathogens, their roles in anti-infection immunity have frequently been underestimated. To estimate whether adequate dietary iron intake would help defend against pathogenic bacterial infection, mice were fed iron-deficient (2 mg kg-1 feed), iron-sufficient (35 mg kg-1 feed), or iron-enriched diet (350 mg kg-1 feed) for 12 weeks, followed by oral infection with Salmonella typhimurium. Our results revealed that dietary iron intake improved mucus layer function and decelerated the invasion of the pathogenic bacteria, Salmonella typhimurium. Positive correlations between serum iron and the number of goblet cells and mucin2 were found in response to total iron intake in mice. Unabsorbed iron in the intestinal tract affected the gut microbiota composition, and the abundance of Bacteroidales, family Muribaculaceae, was positively correlated with their mucin2 expression. However, the results from antibiotic-treated mice showed that the dietary iron-regulated mucin layer function was not microbial-dependent. Furthermore, in vitro studies revealed that ferric citrate directly induced mucin2 expression and promoted the proliferation of goblet cells in both ileal and colonic organoids. Thus, dietary iron intake improves serum iron levels, regulates goblet cell regeneration and mucin layer function, and plays a positive role in the prevention of pathogenic bacteria.

Abstract
Background To investigate the regulation mechanism of hematopoiesis of Siwu paste (SWP) in anemia rats, which is a classic Chinese prescription used for nourishing blood or blood deficiency over 1000 years. Methods Blood cell and biochemical analysis were used to evaluate the hematopoietic function of SWP in anemia rats. The intestinal microbial composition was analyzed with 16S rRNA gene sequencing, and the metabolites were profiled using UPLC-TripleTOF system nontargeting metabolomics. Results SWP can improve the levels of red blood cells, hemoglobin, platelet, hematocrit value, white blood cells, lymphocyte, EPO, TPO, and GM-CSF in anemia rats, and significantly change the microbial community and its metabolites. The correlation analysis of intestinal microbiota-hematopoietic efficacy shows that 13 kinds of different intestinal flora were related to hematopoietic efficacy, in which Prevotella_1, Prevotella_9, Lactobacillus, and norank_f__Muribaculaceae were significantly positively correlated with hematopoiesis, nine kinds of intestinal flora are negatively correlated with hematopoietic effect. Compared with anemia rats, 218 potential metabolic biomarkers and 36 metabolites with significant differences were identified in the SWP treatment group, and the key metabolites were mainly amino acids and lipids. An in-depth analysis of metabolic pathways showed that SWP mainly affected 7 metabolic pathways, including aminobenzoic acid degradation and tryptophan metabolism. Conclusion The study provides novel insights into the regulation of hematopoiesis of SWP in anemia rats that were correlated with gut microbiota and the metabolites, which through the restoration of the firmicutes/bacteroidetes ratio.

Abstract
In this study, benzylpiperidine, the active group of donepezil (DNP), was connected with the neurotransmitter phenylethylamine by square amide, in which the fat chain of phenylethylamine was reduced and the benzene rings were substituted. A series of multifunctional hybrid compounds, including DNP-aniline hybrids (1-8), DNP-benzylamine hybrids (9-14), and DNP-phenylethylamine hybrids (15-21) were obtained and their cholinesterase inhibitory activity and neuroprotection of the SH-SY5Y cell line were determined. Results showed that compound 3 exhibited excellent acetylcholinesterase inhibitory activity with an IC50 value of 4.4 μM, higher than that of positive control DNP and significant neuroprotective effects against H2O2-induced oxidative damage in SH-SY5Y cells with 80.11% viability rate at 12.5 μM, much higher than that of the model group (viability rate = 53.1%). The mechanism of action of compound 3 was elucidated by molecular docking, reactive oxygen species (ROS), and immunofluorescence analysis. The results suggest that compound 3 could be further explored as a lead compound for the treatment of Alzheimer's disease. In addition, molecular docking research indicated that the square amide group formed strong interactions with the target protein. Based on the above analysis, we believe that square amide could be an interesting construction unit in anti-AD agents.

Abstract
Objective This study aimed to explore the differences between Eucommiae cortex (EC) endophytic bacteria from different origins and their effects on the active ingredients of EC. Methods A total of 10 samples of Eucommia ulmoides Oliv. (E. ulmoides) bark were collected from each of the following four regions, namely, Zunyi in Guizhou (GZ), Baokang in Hubei (HUB), Cili in Hunan (HUN), and Loyang in Shaanxi (SX). Subsequently, the contents of the main active ingredients of EC were determined by ultra-performance liquid chromatography (UPLC), and the endophytic bacteria of EC were detected by 16S rRNA sequencing. The relationship between the dominant endophytic bacteria and the active ingredients was investigated by correlation analysis. Results A total of 4,551 different operational taxonomic units (OTUs) were delineated in the four groups of samples, of which 585, 439, 957, and 684 genera were annotated from GZ, HUB, HUN, and SX, respectively. The richness and diversity of endophytic bacteria from different origins were ranked as HUN > SX > GZ or HUB. The analysis demonstrated that there was no significant correlation between the diversity and richness of endophytic bacteria in EC and its active ingredients. Nevertheless, notable variations in the community structures of endophytic bacteria were observed across different origins, and they had a considerable impact on certain active ingredients in EC. Comamonas and Cedecea were the dominant genera. Characteristic bacteria of different origins could be clearly distinguished. Simultaneous, significant correlations had been identified between some characteristic endophytic bacteria derived from different origins and active ingredients of EC. For example, Delftia, a characteristic bacterium from GZ, showed a significant positive correlation with pinoresinol diglucoside. Paenibacillus and Klebsiella, two characteristic bacteria from HUB, exhibited significant positive correlations with geniposidic acid. Thauera, a characteristic bacterium from HUN, demonstrated a significant positive correlation with geniposide. Brevundimonas, a characteristic bacterium from SX, displayed a significant positive correlation with pinoresinol diglucoside. Conclusion There was a complex correlation between EC endophytic bacteria and active ingredient content, while EC endophytic bacteria from different origins had significant differences at the genus level.

Abstract
Knowing how workers return to work is a key policymaking issue for economic recovery in the post-COVID-19 era. This paper uses country-wide time-series mobile phone big data (comparing monthly and annual figures), obtained between February 2019 and October 2019 and between February 2020 and October 2020, to discover the spatial patterns of rural migrant workers' (RMWs') return to work in China's three urban agglomerations (UAs): the Beijing-Tianjin-Hebei Region, the Yangtze River Delta and the Pearl River Delta. Spatial patterns of RMWs' return to work and how these patterns vary with location, city level and human attribute were investigated using the fine-scale social sensing related to post-pandemic human mobility. The results confirmed the multidimensional spatiotemporal differentiations, interaction effects between variable pairs and effects of the actual situation on the changing patterns of RMWs' return to work. The spatial patterns of RMWs' return to work in China's major three UAs can be regarded as a comprehensive and complex interaction result accompanying the nationwide population redistribution, which was affected by various hidden factors. Our findings provide crucial implications and suggestions for data-informed policy decisions for a harmonious society in the post-COVID-19 era.

Abstract
Zearalenone (ZEA) exposure has carcinogenic effects on human and animal health by exhibiting intestinal, hepatic, and renal toxicity. At present, the underlying mechanisms on how ZEA induces apoptosis and damage to tissues still remain unclear. In this study, we aimed to identify genes that modulate the cellular response to ZEA using clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 screening, and further validate novel gene functions to elucidate molecular mechanisms underlying particular biological processes in vivo and in vitro. Two ZEA-resistant cell lines, designated Ov-KCNJ4 and Ov-KCNJ12, were yielded by CRISPR activation screening which had significant changes in ZEA resistance and growth rates. Results showed that ZEA could interact with the cell membrane proteins KCNJ4 and KCNJ12, inducing cell cycle arrest, disruption of DNA replication and base excision repair. Overexpression of KCNJ4 and KCNJ12 was involved in ZEA resistance by regulating cell cycle to neutralize toxicity, sustaining mitochondrial morphology and function via attenuating the damage from oxidative stress in the KCNJ4-mitoKATP pathway. In vivo experiments showed that AAV-KCNJ4 delivery significantly improved ZEA-induced renal impairment and increased antioxidative enzyme activity by improving mitochondrial function. Our findings suggest that increasing potassium channel levels may be a putative therapeutic target for mycotoxin-induced damage.

Abstract
BACKGROUND AND AIMS Monocyte-derived macrophages (MoMFs), a dominant population of hepatic macrophages under inflammation, play a crucial role in liver fibrosis progression. The spleen serves as an extra monocyte reservoir in inflammatory conditions; however, the precise mechanisms of involvement of the spleen in the pathogenesis of liver fibrosis remain unclear. APPROACH AND RESULTS By splenectomy and splenocyte transfusion, it was observed that splenic CD11b+ cells accumulated intrahepatically as Ly6Clo MoMFs to exacerbate CCl4 -induced liver fibrosis. The splenocyte migration into the fibrotic liver was further directly visualized by spleen-specific photoconversion with KikGR mice and confirmed by CD45.1+ /CD45.2+ spleen transplantation. Spleen-derived CD11b+ cells purified from fibrotic livers were then annotated by single-cell RNA sequencing, and a subtype of CD11b+ CD43hi Ly6Clo splenic monocytes (sM-1s) was identified, which was markedly expanded in both spleens and livers of mice with liver fibrosis. sM-1s exhibited mature feature with high expressions of F4/80, produced much ROS, and manifested preferential migration into livers. Once recruited, sM-1s underwent sequential transformation to sM-2s (highly expressed Mif, Msr1, Clec4d, and Cstb) and then to spleen-derived macrophages (sMφs) with macrophage features of higher expressions of CX3 CR1, F4/80, MHC class II, and CD64 in the fibrotic hepatic milieu. Furthermore, sM-2s and sMφs were demonstrated capable of activating hepatic stellate cells and thus exacerbating liver fibrosis. CONCLUSIONS CD11b+ CD43hi Ly6Clo splenic monocytes migrate into the liver and shift to macrophages, which account for the exacerbation of liver fibrosis. These findings reveal precise mechanisms of spleen-liver axis in hepatic pathogenesis and shed light on the potential of sM-1 as candidate target for controlling liver diseases.

Abstract
The generation of reactive oxygen species (ROS) mediated by minerals and/or microorganisms plays a vital but underappreciated role in affecting carbon and nutrient cycles at soil-water interfaces. It is currently unknown which interactions between microbial communities and iron (Fe) minerals produce hydroxyl radical (HO•), which is the strongest oxidant among ROS. Using a series of well-controlled anoxic incubations of soil slurries, we demonstrated that interactions between microbial communities and Fe minerals synergistically drove HO• production (up to ∼100 nM after 21-day incubation). Microorganisms drove HO• generation in anoxic environments predominantly by modulating iron redox transformation that was more prominent than direct production of ROS by microorganisms. Among the microbial communities, Geobacter, Paucimonas, Rhodocyclaceae_K82, and Desulfotomaculum were the key genera strongly affecting HO• production. In manured soils, the former two species had higher abundances and were crucial for HO• production. In contrast, the latter two species were mainly abundant and important in soils with mineral fertilizers. Our study suggests that abundant highly reactive oxidant HO• can be generated in anoxic environments and the microbial community-mediated redox transformations of iron (oxyhydr)oxides may be responsible for the HO• production. These findings shed light on the microbial generation of HO• in fluctuating redox environments and on consequences for global C and nutrient cycling.

Abstract
Adenoid cystic carcinoma (ACC) of the breast (breast ACC) is a rare tumor, especially in men, with only 17 cases reported in the literature. Owing to this rarity, male breast ACC is susceptible to missed or incorrect diagnoses, and data on treatment options and prognosis is also scarce. Herein, we report a case of a male patient with primary breast ACC and performed a detailed clinicopathological analysis of the 17 cases reported in the literature. A 38-year-old Chinese man patient developed right-sided breast nipple retraction in 2013 and presented to our hospital in 2015 with a palpable mass in the right breast for four days. B-scan ultrasound indicated the presence of a solid space-occupying lesion in the right breast. Breast Imaging Reporting and Data System (BI-RADS) classified the lesion as category 4B, and mammography showed a right breast nodule classified as BI-RADS 4C. Modified radical mastectomy for breast cancer was performed on the right breast. Microscopic examination of the excised tissue revealed diffuse tumor invasion of the subcutaneous fibers and adipose tissue, with tumor cells arranged in cribriform, tubular, and microcystic patterns. Immunohistochemical staining indicated that the glandular epithelial cells were positive for CD117, CK7, and Ki67 (approximately 30%) and negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2, while the myoepithelial/basal cells were positive for P63, CK5/6 and S-100. Moreover, basement membrane materials were positive for collagen type IV. Molecular pathology analysis by fluorescence in situ hybridization revealed that the tumor was negative for MYB rearrangements. The patient was followed up for 82 months with no tumor recurrence or metastasis. According to the current literature, mastectomies have a better prognosis than lumpectomy. Accurately identifying the diagnosis of male breast ACC and considering the surgery of mastectomy may be the key factors for patients to obtain a good prognosis based on the microscopic characteristics of the tumor.

Abstract
As an emerging contaminant, tungsten's distribution and speciation in soils are far from understood. In this study, two soil profiles near a typical abandoned tungsten smelter in Hunan Province, China were collected and investigated, to ascertain the binding and association of tungsten with different soil components and subsequently to understand its mobility. The data showed that past tungsten smelting activities resulted in elevated concentrations of both tungsten and arsenic in the soil profiles, both of which ranged from dozens of to a few hundred mg/kg. Nano-scale secondary ion mass spectrometry (NanoSIMS) was employed to quantify the distribution and association of tungsten with various other elements. Combined with sequential extraction and mineralogical analysis, the data from NanoSIMS showed that aluminosilicates including kaolinite and illite were the most important mineral hosts for tungsten, whereas arsenic was predominantly bound to iron (oxyhydr)oxides. Additional data from 13C nuclear magnetic resonance and X-ray photoelectron spectroscopy revealed that soil organic matter retained tungsten in deep soils (>70 cm) by binding tungsten through carboxyls on aromatic rings. Compared to arsenic, tungsten migrated deeper in the soil profiles, suggesting its higher mobility and potential risk to groundwater quality.

Abstract
BACKGROUND Iron deficiency and overload during pregnancy damage to maternal and fetal health. Placenta as an organ for the transport of nutrients between mother and fetus protects fetus from the harmful effects of iron deficiency and iron overload through regulation of placental iron homeostasis. METHODS To determine the effect of dietary iron supplementation during pregnancy on reproduction and the mechanism of placental iron regulation, we designed dietary high iron (HI: 344 mg/kg), medium iron (MI: 40 mg/kg), low iron (LI: 2 mg/kg) groups of pregnant female mice fed ferrous citrate 2 weeks before mating to 18.5 days of gestation. RESULTS We find dietary iron supplementation during pregnancy effect maternal liver iron, placental iron, hemoglobin and fetal iron. Dietary iron significantly improves reproductive performance as litter weight and fetal weight. Correlation analysis suggest placental iron increased with liver iron, higher and lower liver iron is not conducive to the accumulation of fetal iron, placental iron deficiency and excess reduce litter weight. Placental transcriptome analysis revealed DEGs with the same trend in HI and LI groups compared with MI group, dietary iron may change biology process of ion transport and gland development in placenta. Granzyme may affect the placental trophoblast structure prior to delivery with iron overload uniquely. CONCLUSION This research highlights the importance of moderate iron supplements in pregnancy due to damage of reproduction by affecting placental function under different dose of maternal iron supplementation.

Abstract
Multi-omics were applied to compare the risks and benefits of ferrous sulfate (FeSO4) and ferrous bisglycinate (FebisGly) in pigs in the current study. The FebisGly group showed reduced triglyceride (TG) and triglyceride/total cholesterol (TG/CHOL) values in the serum and reduced malondialdehyde (MDA) and increased glutathione (GSH) levels in the duodenum. Transcriptome analysis revealed that differentially expressed genes in the duodenum were enriched in oxidative phosphorylation, AMPK, and FOXO signaling pathways between FeSO4 and FebisGly groups. AMPK phosphorylation and FOXO3 protein expressions were significantly increased in the FebisGly group. Bacterial 16S rRNA gene sequence analysis revealed significantly reduced alpha diversity in the FeSO4 group and increased Firmicutes, reduced Bacteroidetes, and Proteobacteria abundances in the FebisGly group. Targeted metabolome revealed notably increased lithocholic acid (LCA), glycolithocholic acid (GLCA), hyodeoxycholic acid (HDCA), ursodeoxycholic acid (UDCA), and glycoursodeoxycholic acid (GUDCA) in the FebisGly group. RDA analysis indicated that Fusobacteria was positively correlated with TG and TG/high-density lipoprotein in the FeSO4 group while Christensenellaceae_R-7_group, Ruminococcaceae_UCG-002, and Ruminococcaceae_UCG-005 were positively correlated with UDCA and GLCA in the FebisGly group. According to the current study, FebisGly improves serum lipid metabolism, modulates intestinal antioxidant capacity via the AMPK/FOXO pathway, and reconstitutes gut microbiota and bile acid profiles in pigs.

Abstract
Cordyceps is a large group of entomogenous, medicinally important fungi. In this study, we sequenced, assembled, and annotated the entire mitochondrial genome of Ophiocordyceps xuefengensis, in addition to comparing it against other three complete cordyceps mitogenomes that were previously published. Comparative analysis indicated that the four complete mitogenomes are all composed of circular DNA molecules, although their sizes significantly differ due to high variability in intron and intergenic region sizes in the Ophiocordyceps sinensis and O. xuefengensis mitogenomes. All mitogenomes contain 14 conserved genes and two ribosomal RNA genes, but varying numbers of tRNA introns. The Ka/Ks ratios for all 14 PCGs and rps3 were all less than 1, indicating that these genes have been subject to purifying selection. Phylogenetic analysis was conducted using concatenated amino acid and nucleotide sequences of the 14 PCGs and rps3 using two different methods (Maximum Likelihood and Bayesian analysis), revealing highly supported relationships between O. xuefengensis and other Ophiocordyceps species, in addition to a close relationship with O. sinensis. Further, the analyses indicated that cox1 and rps3 play important roles in population differentiation. These mitogenomes will allow further study of the population genetics, taxonomy, and evolutionary biology of medicinally important cordyceps species.

Abstract
Accumulating evidence implicates that offspring are susceptible to paternal alterations in numerous fetal disorders, such as growth and metabolic defects. However, less study has been conducted to define the relationship between paternal zinc deficiency (ZnD) and energy metabolism of offspring. In the present study, we used a paternal ZnD exposure (Zn at 0.3 μg/g) model to test energy metabolism of male and female offspring with the intervention of diet type (high-fat diet and low-fat diet). Our results demonstrated that paternal ZnD decreased body weight (BW) gain per week (P < 0.01) and ME intake per week (P < 0.05) at 11 weeks in male offspring with high-fat diet intervention but not in female offspring. Further, anabolism and catabolism of hepatic energy products also exhibited alterations. ZnD attenuated liver glucose but increased lipids content accompanied with elevated adiponectin and reduction in leptin level in serum, which exhibited lipid metabolic disturbance and smaller ratio of liver weight to BW in male but not female offspring. The qRT-PCR and liver energy metabolites analysis revealed that paternal ZnD mainly induced reduction in glucose tolerance and lowered glucose uptaking ability in male offspring and thereby alleviated glycolysis and the tricarboxylic acid cycle (TCA) cycle, which displayed a male gender-dependency. Therefore, we propose that paternal ZnD abolishes metabolic effects in male offspring induced by diet type intervention. Our findings reveal a novel link between paternal Zn-D and offspring energy metabolism.

Abstract
The INO80 chromatin remodeling complex plays an essential role in the regulation of gene transcription, which participate in a variety of important biological processes in cells including DNA repair and DNA replication. Difference from the yeast INO80 complex, metazoan INO80 complex have the specific subunit G, which is known as nuclear factor related to kappaB binding protein (NFRKB). Recently, NFRKB has been received much attention in many aspects, such as DNA repair, cell pluripotency, telomere protection, and protein activity regulation. To dig the new function of metazoan INO80 complex, a better understanding of the role of NFRKB is required. In this review, we provide an overview of the structure and function of NFRKB and discuss its potential role in cancer treatment and telomere regulation. Overall, this review provides an important reference for further research of the INO80 complex and NFRKB.

Abstract
Dissolved organic matter (DOM) represents the most mobile and reactive pool of soil organic matter (SOM). Climate changes, such as global warming and altered precipitation exert considerable influences on the quality and quantity of soil DOM. However, rare reports have focused on the interactive effects of soil warming and increased precipitation. In the present study, we conducted a 90-day incubation experiment to investigate how the concentration, source and chemical composition of DOM from an Alfisol respond to the variations of temperatures (15, 30 and 45 °C) and moistures (40%, 60%, and 80% of saturated soil water content). Four DOM components were identified through fluorescence excitation emission matrix (EEM)-parallel factor analysis (PARAFAC). Increased temperature alone aggravated the decomposition of plant-derived aromatic components (C2 and C4) but promoted the accumulation of microbial-derived aliphatic carbon (C1) and tryptophan-like component (C3). Increased fungi/bacteria ratio with warming was responsible for the decomposition of plant-derived components. Warming-induced disassociation of Ca-bearing mineral to colloidal Ca facilitated the accrual of microbial-derived aliphatic DOM. Humidification alone and humidification + warming significantly increased the concentration of DOM and the percentage of plant-derived aromatic carbon (C2, C4), which was attributed to the release of Fe-bearing mineral-OC. Based on the above findings along with the results of two-way ANOVA and Variation partition analysis, we infer that moisture will play a dominant role in regulating the chemical composition of DOM in Alfisols under both warming and humidification which in turn impact global C cycling and the ultimate climate.

Abstract
Purpose: To investigate the radiosensitizing effect of polysaccharide from Schisandrae Chinensis fruit (SCFP) on ovarian cancer SKOV3 cell line.
Methods: The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to evaluate SKOV3 cell viability. Caspase-3, caspase-9, Bax, and Bcl-2 levels in SKOV3 cells were assessed by enzyme-linked immunosorbent assay (ELISA). Furthermore, mRNA expression of caspase-3, caspase-9, Bax and Bcl-2 in SKOV3 cells were determined using quantitative real-time polymerase chain reaction (RT-qPCR) assay.
Results: β-Irradiation (10 Gy) did not show obvious inhibitory effects on SKOV3 cell proliferation. However, SCFP at a dose of 1.25, 2.5 and 5 mg/mL significantly enhanced the radiosensitivity of SKOV3 cells to β-irradiation (p < 0.01). Furthermore, SCFP at concentrations of 1.25, 2.5 and 5 mg/mL significantly increased the levels of caspase-3, caspase-9 and Bax in SKOV3 cells, but decreased that of Bcl-2 (p < 0.01). In addition, SCFP combined with β-irradiation up-regulated mRNA expression of caspase-3, caspase-9 and Bax (p < 0.01), but down-regulated that of Bcl-2 in SKOV3 cells (p < 0.01).
Conclusion: SCFP significantly enhances the sensitivity of nasopharyngeal carcinoma SKOV3 cells to β-irradiation. The possible mechanism of sensitization might be correlated to the induction of mitochondria-mediated apoptosis. This research provides a scientific basis for the development of SCFP for the treatment of ovarian cancer.

Abstract
The iron status of sows has a great influence on reproductive performance. Iron deficiency reduces reproductive performance and newborn piglet survival rate of sow. The hemoglobin is a potential predictor for the iron status of sows and is convenient for rapid detection in pig farms. However, the relationship between iron status, hemoglobin, placental trace elements, and reproductive performance remains unclear. In this study, the hemoglobin and reproductive performance of more than 500 sows with first to sixth parities at different gestation stages (25, 55, 75, 95, and 110 d of gestation) in two large-scale sow farms were collected, and the content of placental Fe, Zn, Mn, and Cu was analyzed. The results show that hemoglobin levels of sows during pregnancy (days 75, 95, and 110) decreased significantly (P < 0.001). As the parity increases, the hemoglobin levels of sows at days 25 and 55 of gestation and placental mineral element contents including Fe, Zn, Mn, and Cu at delivery decreased (P < 0.05), while the litter size, birth alive, and litter weights increased gradually (P < 0.001). Furthermore, hemoglobin during pregnancy had a negative linear correlation with litter weight and average weight (P < 0.05), and higher hemoglobin at day 25 of gestation may reduce the number of stillbirths (P = 0.05), but higher hemoglobin at day 110 of gestation may tend to be a benefit for the birth (P = 0.01). And there was a significant positive linear correlation between hemoglobin at day 110 of gestation and placental Fe and Mn levels (P = 0.002, P = 0.013). There was also a significant positive linear correlation among Fe, Zn, Mn, and Cu in the placenta (P < 0.001). The levels of Fe, Zn, and Mn in the placental at delivery were positively related to the average weight of the fetus (P = 0.048, P = 0.027, P = 0.047), and placental Cu was linearly correlated with litter size (P = 0.029). Our research revealed that the requirements for iron during gestation were varied in different gestation periods and parities. The feeds should be adjusted according to the gestation periods, parities, or iron status to meet the iron requirements of sows and fetal pigs.

Abstract
This work investigates the electrochemical oxidation (EO) of diclofenac (DCF) in water with Ti/Ti4O7, Ti/Ru-Ir, Ti/Sb-SnO2 and Ti/PbO2 electrodes. Scanning electron microscope and X-ray diffraction results suggest that Ti/Ti4O7 has porous stacked surface morphology and Ti/Sb-SnO2 possesses the smallest grain size. Linear sweep voltammetry test results indicate that PbO2 has the highest oxygen evolution potential, while Ti/Ti4O7 and Ti/Ru-Ir show better oxygen evolution activity. DCF degradation results reveal that PbO2 possessed the highest DCF removal (RDCF = 99.2%) and chemical oxygen demand (COD) removal (RCOD = 97.0%), the fastest COD degradation rate (k = 0.0275 min-1, R2 = 0.964), the lowest specific energy consumption (ECDCF = 1.81 kWh.g DCF-1, ECTOC = 6.90 kWh.g TOC-1). The toxicity variation of DCF during EO process on PbO2 is rise first and then to fall. Considering the differences of the four electrodes in residual, conversion and mineralization aspects, mineralization selectivity (MS) was proposed to estimate the mineralization inclination of electrodes during EO process, and PbO2 displays the strongest mineralization inclination (MS = 0.594). In addition, the possible degradation pathway of DCF on PbO2 electrode indicates a composite behavior of conversion and mineralization. All of them above indicate the promising application potential of PbO2 in lower concentration pharmaceuticals and personal care products wastewater treatment. Moreover, MS could be employed as a supplementary index to assess the different inclinations of this composite behavior on various electrodes used for electrochemical treatment of organics in later studies.

Abstract
AIM To establish an ultrasound-based radiomics model through machine learning methods and then to assess the ability of the model to differentiate infected focal liver lesions from malignant mimickers. MATERIALS AND METHODS A total of 104 patients with infected focal liver lesions and 485 patients with malignant hepatic tumours were included, consisting of hepatocellular carcinoma (HCC), cholangiocarcinoma (CC), combined hepatocellular-cholangiocarcinoma (cHCC-CC), and liver metastasis. Radiomics features were extracted from grey-scale ultrasound images. Feature selection and predictive modelling were carried out by dimensionality reduction methods and classifiers. The diagnostic effect of the prediction mode was assessed by receiver operating characteristic (ROC) curve analysis. RESULTS In total, 5,234 radiomics features were extracted from grey-scale ultrasound image of every focal liver lesion. The ultrasound-based radiomics model had a favourable predictive value for differentiating infected focal liver lesions from malignant hepatic tumours, with an area under the curve (AUC) of 0.887 and 0.836 (HCC group), 0.896 and 0.766 (CC group), 0.944 and 0.754 (cHCC-CC group), 0.918 and 0.808 (liver metastasis group), and 0.949 and 0.745 (malignant hepatic tumour group) for the training set and validation set, respectively. CONCLUSIONS Ultrasound-based radiomics is helpful in differentiating infected focal liver lesions from malignant mimickers and has the potential for use as a supplement to conventional grey-scale ultrasound and contrast-enhanced ultrasound (CEUS).

Abstract
BACKGROUND HER2 was a recognized oncogene that promoted the development and metastasis of breast cancer, but its positive expression rate in invasive ductal carcinoma (IDC) was much lower than that in ductal carcinoma in situ (DCIS). The correlation between the occurrence and development of breast cancer and the amplification and overexpression of HER2 gene alone was still controversial. 14-3-3ζ had a strong protein binding ability and a variety of functions, mainly through the interaction with other proteins to exert its unique biological activities. However, influence and interaction relationship of the two proteins on the development of IDC was not clear. Furthermore, the mutual effect mechanism of synergy effect on lymph node metastasis of IDC was not known well too. METHODS Immunohistochemistry experiment was performed to detect expression status of 14-3-3ζ, HER2, TGF-β, p53 and Gli2 in paraffin-embedded samples respectively, including 30 cases of normal breast tissue, 30 cases of usual ductal hyperplasia (UDH), 30 cases of atypical ductal hyperplasia (ADH), 30 cases of DCIS and 120 cases of IDC. RESULTS The positive expression rates of 14-3-3ζ/HER2 in Normal group, UDH group, ADH group, DCIS group and IDC group were 30%/0.00%, 26.7%/0.00%, 53.3%/33.3%, 46.7%/53.3% and 50%/24.2%, respectively. Compared with Normal group or UDH group, the expression of 14-3-3ζ was significantly increased in ADH, DCIS and IDC groups. 14-3-3ζ was overexpressed in only 4 of the 16 DCIS cases with HER2 overexpression (25.0%, 4/16), but it was overexpressed in 7 of the 9 IDC cases with DCIS (77.8%, 7/9). Among HER2 overexpression cases, 14-3-3ζ overexpression was significantly different between DCIS group and IDC with DCIS group (P = 0.017). In 18 IDC cases with lymph node metastasis and HER2 overexpression, 14-3-3ζ was overexpressed in 15 cases (83.3%, 15/18), while in the 11 IDC cases without lymph node metastasis, 14-3-3ζ and HER2 were overexpressed in only 5 cases (45.5%, 5/11). Co-overexpression of 14-3-3ζ and HER2 was positively correlated with occurrence of lymph node metastasis (P = 0.048). TGF-β was overexpressed in both precancerous lesion group and IDC group compared with normal group. Compared with the IDC group without lymph node metastasis, TGF-β expression was significantly increased in the IDC group with lymph node metastasis (P = 0.015). In IDC cases with 14-3-3ζ and HER2 co-overexpression, the expression of p53 in IDC with lymph node metastasis was significantly decreased (P = 0.010), while the expression of Gli2 was significantly increased compared with IDC cases without lymph node metastasis (P = 0.038). The co-overexpression of 14-3-3ζ and HER2 was positively correlated with ER negative expression (P < 0.001) and PR negative expression (P = 0.038), respectively. CONCLUSION 14-3-3ζ synergistic with HER2 could promote the occurrence and development of breast IDC and induce the lymph node metastasis of IDC, suggesting that combined overexpression of 14-3-3ζ and HER2 would lead to higher invasion and metastasis risk of breast cancer. It was speculated that the combined detection of 14-3-3ζ and HER2 would be one of the key factors affecting the clinical treatment decision and prognosis.

Abstract
Hydrogen peroxide (H2O2), an important reactive oxygen species (ROS) with unique destructive oxidation properties, can be produced in lysosomes to fight off pathogens. Although many fluorescent probes have been developed for the detection and imaging of H2O2, the development of a ratiometric fluorescent probe for H2O2 detection and imaging in lysosomes and an inflammation model remains rather scarce. Therefore, it is important to develop an efficient tool for monitoring H2O2 in inflamed tissues to evaluate the physiological and pathological relationship between inflammation and lysosomal H2O2. In this work, a new naphthalimide-based lysosome-targeting fluorescent probe (NPT-H2O2) for ratiometric detection and imaging was developed in vitro and in vivo. The probe exhibited two well-resolved emission peaks separated by 125 nm, rapid response (<40 s), and high selectivity and sensitivity toward H2O2, as well as low cytotoxicity in vitro. Inspired by prominent features of these results, we further successfully applied NPT-H2O2 for H2O2 imaging with a dual-channel in living cells, demonstrating that our probe NPT-H2O2 was targeted in the lysosomes. Finally, NPT-H2O2 was used for H2O2 detection in inflamed tissues and achieved satisfactory results. We predict that our probe can be used as a powerful tool to reveal the relationship between physiology and pathology of inflammation and lysosomal H2O2. Hydrogen peroxide (H2O2), an important reactive oxygen species (ROS) with unique destructive oxidation properties, can be produced in lysosomes to fight off pathogens.![]()

Abstract
Although the contribution of calcium ion (Ca2+) to stabilizing organic carbon (OC) in soils has been known for years, we still have a limited understanding of the quantity and molecular composition of Ca2+ bound SOC (Ca-OC) evolution in response to long-term fertilization. Here we report the role of Ca2+ in the accumulation of OC in the topsoil (0-20 cm) from two long-term (25-37 years) fertilization experiment sites. Approximately 4.54-19.27% and 9.00-25.15% of SOC was bound with Ca2+ in the Ferric Acrisol and Fluvic Cambisol, respectively. The application of NPK mineral fertilizers (NPK) decreased (p < 0.05) the Ca-OC stocks from 3.40 t ha-1 to 0.96 t ha-1 and from 2.03 t ha-1 to 1.17 t ha-1 in the Ferric Acrisol and Fluvic Cambisol, respectively. Swine manure (M) addition did not change (p > 0.05) the Ca-OC stock in Ferric Acrisol, but enhanced (p < 0.05) that from 2.03 t ha-1 to 9.75 t ha-1 in Fluvic Cambisol. Fourier transform infrared and carbon (1s)-near X-ray absorption spectroscopies showed that Ca2+ was mainly bound with aromatic carbon and carboxylic carbon. Long-term M fertilization facilitated the binding of Ca2+ with O-alkyl C, suggesting an increment of Ca-linked polysaccharide. Calcium ion was preferentially associated with 13C enriched organic matter (OM). Mineral fertilization promoted the 13C-enriched organic compounds in the Ca-OC, while organic fertilization facilitated the binding of 13C-depleted organic C with Ca2+. This study suggests that Ca-OC may be a potentially vital and stable OC pool in arable soils, and provides direct evidence for the preferential association of OC with Ca2+ in edaphic environments.

Abstract
BACKGROUND Iron supplements are limited by their poor absorption and low efficacy. A circadian feeding schedule would affect the circadian rhythm and improve nutrient metabolism. In this study, 18 iron-deficient piglets were randomly assigned to three groups: a control group receiving a constant diet with mid-iron (MI), a 'HL' group receiving a high-iron (HI) diet at 8:00 h and a low-iron (LI) diet at 18:00, and an 'LH' group receiving a LI diet at 8:00 and a HI diet at 18:00. The effects of circadian iron administration on iron absorption, iron status, and biological rhythm in iron-deficient piglets were investigated. RESULTS Serum iron and hemoglobin improved significantly (P < 0.05) but did not significantly differ in the circadian iron-feeding groups (P > 0.05). Iron concentration in the liver and spleen was significantly higher in the LH group than in the HL group (P < 0.05), and mRNA expression of divalent metal transport 1 (DMT1), cytochrome B (CYBRD1) and ferroportin (FPN) genes in the duodenum was significantly elevated in the LH group (P < 0.05). The clock-related genes showed differential expression in the duodenum, with greater mRNA expression for period (Per2) and cryptochrome (Cry1 and Cry2) in the LH group (P < 0.05). CONCLUSION Circadian iron administration affected iron absorption and iron storage in pigs. Iron supplementation in the evening might be a more effective pattern for iron utilization. The rhythmic system in the intestine, driven by the time, played an important role in this process. © 2020 Society of Chemical Industry.

Abstract
This experiment was conducted to investigate the effects of zinc oxide/zeolite on growth performance, serum biochemistry, intestinal morphology, and microflora of weaned piglets. Two hundred and fifty-six weaned piglets (Duroc × Landrace × Large) at 21 days of age were randomly assigned to 2 groups with 8 replicates and 16 piglets in each pen. The diets of high dose of zinc oxide group (HD-ZnO) supplemented with 1500 mg/kg zinc as zinc oxide, but the diet of experimental group supplemented with 500 mg/kg zinc as zinc oxide that supported on zeolite (SR-ZnO). The experiment was conducted for 2 weeks after weanling. The results showed replacement of high-dosed zinc oxide by SR-ZnO had no significant effects on growth performance and intestinal morphology. However, the dietary supplementation of SR-ZnO reduced the diarrhea rate (P < 0.05), increased the activity of serum alkaline phosphatase (ALP) (P < 0.01), and tended to reduce zinc release in stomach (P = 0.06) and increase serum total protein (TP) (P = 0.07). Although there were no significant effects in ileal microflora on α diversity, the abundance of Campylobacters was found significantly decreased (P < 0.05), whereas the abundance of Clostridium was increased (P < 0.05) after lower-dosed SR-ZnO replacement. It is revealed that replacement of HD-ZnO (1500 mg/kg) by SR-ZnO (500 mg/kg) in creep feed could improve the zinc bioavailability, regulate the intestinal flora, and alleviate the postweaning diarrhea in weaned piglets. Accordingly, the application of SR-ZnO would reduce the zinc in feed and therefore benefits for the ecological environment.

Abstract
Since the fluctuation of cellular hydrogen sulfide (H2S) is a very important third endogenously generated gaseous signaling molecule and plays a key role in the development of numerous human disorders, the real-time fluorescence detection of H2S in living systems has attracted plenty of interest during past decade. Although a lot of H2S fluorescent probes have been reported, the relationship between the physiology and pathology of H2S in organelles remains unclear, especially for inflammatory tissue. In this work, by adopting a weakly basic morpholine group as the lysosome-targeting site, a naphthalimide derivative as the signal reporter group and a 4-dinitrobenzene-ether (DNB) as fluorescence signal quencher and H2S-selective recognition moiety, we reported a new lysosome-targeting TP fluorescent probe LyNP-H2S for H2S detection and imaging in living cells and inflamed tissues. The probe LyNP-H2S exhibits very low fluorescence signal in the absence of H2S, and displays a significant 262-fold fluorescence intensity enhancement in the presence of H2S at 540 nm. Moreover, LyNP-H2S has the capability of quantitative detection of H2S at concentrations ranging from 0 to 12.0 μM (limit of detection = 9.8 nM), rapid response, as well as high sensitivity and selectivity toward H2S. Impressively, the results of living cell and inflamed tissues imaging test demonstrate that LyNP-H2S has the potentiality of being an ideal probe for real-time H2S detection in biosystems.

Abstract
Nutrient requirements are increased in the late-gestation period due to the faster growth of the foetal-placental unit and maternal erythrocyte mass. Glycine, proline and arginine are important amino acids that could improve foetal growth and development. The present study aims to investigate the effects of a derivative of glycine (N-carbamylglycinate, CGly) on the amino acid profiles and reproductive performances of late gestation sows. Thirty-two multiparous gestating sows (∼d 80) were selected, and randomly assigned into two groups: (1) control and (2) treatment (CGly, 800 mg kg-1) from day 85 of gestation to parturition. The serum amino acid profiles at day 110 of gestation and reproductive performance were investigated. The results showed that dietary supplementation of CGly in the late gestation period significantly improved the levels of glycine (p < 0.05) and proline (p < 0.01) in the serum of the perinatal sows, and thereafter improved the litter birth weights (p < 0.05) and number born alive (p < 0.1). Based on the in vitro studies, the improvement of proline levels is probably due to the induced expression of SLC6A20 and SLC38A2. Further studies should focus on the details of amino acid absorption, especially the competitive and cooperative absorption processes for different amino acids and derivatives.

Abstract
This study investigated the different addition levels of iron (Fe) in growing-finishing pigs and the effect of different Fe levels on growth performance, hematological status, intestinal barrier function, and intestinal digestion. A total of 1,200 barrows and gilts ([Large White × Landrace] × Duroc) with average initial body weight (BW; 27.74 ± 0.28 kg) were housed in 40 pens of 30 pigs per pen (gilts and barrows in half), blocked by BW and gender, and fed five experimental diets (eight replicate pens per diet). The five experimental diets were control diet (basal diet with no FeSO4 supplementation), and the basal diet being supplemented with 150, 300, 450, or 600 mg/kg Fe as FeSO4 diets. The trial lasted for 100 d and was divided into the growing phase (27 to 60 kg of BW) for the first 50 d and the finishing phase (61 to 100 kg of BW) for the last 50 d. The basal diet was formulated with an Fe-free trace mineral premix and contained 203.36 mg/kg total dietary Fe in the growing phase and 216.71 mg/kg in the finishing phase based on ingredient contributions. And at the end of the experiment, eight pigs (four barrows and four gilts) were randomly selected from each treatment (selected one pig per pen) for digesta, blood, and intestinal samples collection. The results showed that the average daily feed intake (P = 0.025), average daily gain (P = 0.020), and BW (P = 0.019) increased linearly in the finishing phase of pigs fed with the diets containing Fe. On the other hand, supplementation with different Fe levels in the diet significantly increased serum iron and transferrin saturation concentrations (P < 0.05), goblet cell numbers of duodenal villous (P < 0.001), and MUC4 mRNA expression (P < 0.05). The apparent ileal digestibility (AID) of amino acids (AA) for pigs in the 450 and 600 mg/kg Fe groups was greater (P < 0.05) than for pigs in the control group. In conclusion, dietary supplementation with 450 to 600 mg/kg Fe improved the growth performance of pigs by changing hematological status and by enhancing intestinal goblet cell differentiation and AID of AA.

Abstract
Background To evaluate role of microRNA (miRNA)-377-3p on the remission of ovarian cancer (OC) cell proliferation, invasion, and interstitial transition in vivo and vitro. Methods SKOV3 cells were used as the object of in vitro research and four-week-old immunodeficient BABL/c female nude mice were used to form the xenograft model. Cell models were constructed by transfecting NC mimics, miR-377 mimic, plasmid cloning DNA (pcDNA), pc-matrix metalloproteinase (MMP)-16, or co-transfecting miR-377 mimic and pc-MMP-16. TargetScan software was used to predict the targeting relationship between miRNA-377-3p and MMP-16 in OC cells. The combination of miRNA-377-3p and MMP-16 was detected by dual luciferase report experiment. miRNA expression levels of miRNA-377-3p and MMP-16 in each transfection group cells were detected by reverse transcription-polymerase chain reaction (RT-PCR). The proliferation of SKOV3 cells were assessed by 5-ethynyl-2'-deoxyuridine (EdU) staining and microtubule formation, while the invasion ability of SKOV3 cells was detected by Transwell assay. Protein expression levels of MMP-16, survivin, Ki67, vascular endothelial growth factor (VEGF), E-cadherin, and N-cadherin were detected by Western blot (WB), and the positive cells of Ki67 and VEGF were detected by immunohistochemistry (IHC). Results MMP-16 overexpression markedly increased the EDU-positive cell percentage, upregulated survivin and Ki67 levels, increased the number of invasive cells per field, and enhanced VEGF and N-cadherin expression. Importantly, co-transfection of miRNA-377-3p and MMP-16 reversed these abnormal phenomena. Xenotransplantation mouse models were formed by injecting SKOV-3 cells subcutaneously. Tumor size, tumor volume, and tumor weight were all reduced in the miR-377-3p mimic–transfected group. The results of IHC indicated that Ki67 and VEGF expression were decreased in the miR-377-3p mimic–transfected group. Conclusions These findings indicate that miR-377-3p could be a promising therapeutic agent for OC cell growth, invasion, and interstitial transition with MMP-16 being its likely target.

Abstract
Seven undescribed indole-based alkaloids, xuefengins A-D and xuefenglasins A-C, were isolated from natural Ophiocordyceps xuefengensis, along with six known alkaloids. Their structures were elucidated by comprehensive spectroscopy, with absolute configurations confirmed by comparison with calculated electronic circular dichroism spectra. Eleven of the isolates were tested for cytotoxicity against the U937, NB4, MCF-7, Hep G2, and A549 cancer cell lines. Two compounds exhibited moderate activities, with IC50 values of 2.83-25.68 μM and 1.54-12.16 μM. Further pharmacological studies showed that these two compounds inhibit cell proliferation by inducing apoptosis, and decreasing p38 and caspase-3 levels in A549 cells.

Abstract
The purpose of the present study was to discover the effects of iron on the intestinal development and epithelial maturation of suckling piglets. Twenty-seven newborn male piglets from 9 sows (3 piglets per sow), with similar body weight, were selected. The 3 piglets from the same sow were randomly divided into 1 of the 3 groups. The piglets were orally administrated with 2 mL of normal saline (CON group) or with 25 mg of iron by ferrous sulfate (OAFe group; dissolved in normal saline) on the 2nd, 7th, 12th, and 17th day, respectively, or intramuscularly injected with 100 mg of iron by iron dextran (IMFe group) on the 2nd day. The slaughter was performed on the 21st day and intestinal samples were collected. Compared with the CON group, iron supplementation significantly increased the length (P < 0.001), weight (P < 0.001), relative weight (P < 0.001), and the length:weight ratio (P < 0.001) of the small intestine in both OAFe and IMFe groups. The villus height (P < 0.001), crypt depth (CD) (P < 0.001), villus width (P = 0.002), and surface area (P < 0.001) in the jejunum of IMFe and OAFe piglets were also greater than those in CON piglets. The mRNA expression of trehalase (Treh; P = 0.002) and sucrase isomaltase (Sis; P = 0.043), markers of epithelial maturation, increased in OAFe and IMFe piglets, respectively. Moreover, enterocyte vacuolization, observed in fetal-type enterocyte, was reduced in OAFe and IMFe piglets, compared with CON piglets. However, no significant difference in the expression of the target genes of wnt/β-catenin signaling pathway was observed. The results indicated that both oral administration and intramuscular injection with iron promoted intestinal development and epithelial maturation in suckling piglets and that the effects of iron may be independent of wnt/β-catenin signaling.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Siwu Paste (SWP) was recorded in the first national Pharmacopoeia of China, "Tai Ping Hui Min He Ji Ju Fang", it showed excellent effects in regulating all syndromes relevant to blood. AIM OF THE STUDY This study aimed to investigate the protective effects of Siwu Paste (SWP) on bone marrow hematopoietic by using rats' model with blood deficiency syndrome induced by chemotherapy. MATERIALS AND METHODS Animal model with blood deficiency syndrome was successfully established by evaluating their peripheral blood cell level and erythrocyte membrane energy metabolism enzyme activity. Serum hematopoietic cytokine levels were detected by using Enzyme-linked immunosorbent assay (ELISA). Hematoxylin-Eosin (HE) staining method was used to observe the pathological morphology of femur bone marrow, and the viability of BMSC was detected by Cell Counting Kit (CCK-8). Furthermore, the expression of toll-like receptor 4 (TLR4), nuclear transcription factor kB (NF-κB), and NOD-like receptor protein 3 (NLRP3) protein in femur bone marrow were detected by using Western-blotting and High-content cell imaging analysis system (HCA). RESULTS Obtained results showed that SWP could significantly improve the status of anemia, regulate the expressions of serum hematopoietic cytokines, and protect bone marrow hematopoietic cells. Furthermore, the expressions of TLR4, NF-κB, and NLRP3 protein were inhibited in bone marrow hematopoietic cells. CONCLUSIONS Siwu Paste (SWP) could recover the bone marrow hematopoietic functions in rats with blood deficiency syndrome. The therapeutic mechanism may be related to the regulation of serum hematopoietic cytokines, and inhibition of TLR4/NF-κB/NLRP3 signaling pathway.

Abstract
OBJECTIVE To investigate the association of Toll-like receptor 4-myeloid differential protein-88- c-Jun N-terminal kinase (TLR4-MyD88-JNK) signaling pathway with inflammatory response in intracranial hemorrhage (ICH) rats and its effect on neuronal apoptosis. PATIENTS AND METHODS The autologous blood was drawn and injected into the brain to establish the rat model of ICH (model group), and the control group was set up. The neurological behavior Longa score was given. The blood and brain tissues of rats were then collected to detect the serum indexes, including glucose (GLU), creatinine (CR), K+ and Na+, and the content of interleukin-6 (IL-6), IL-1β and tumor necrosis factor-α (TNF-α) in each group. The neuronal apoptosis of brain tissues was detected via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. Moreover, the expressions of apoptosis- and TLR4-MyD88-JNK pathway-related genes and proteins were detected via Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and Western blotting. Finally, the association of TLR4-MyD88-JNK signaling pathway with the inflammatory response in ICH rats and its effect on neuronal apoptosis were completely observed. RESULTS MiR-23b was dramatically down-regulated in CC and the low miR-23b expressions were associated with the poor prognosis and worse OS of CC patients. Additionally, the functional assays demonstrated that miR-23b overexpression obviously repressed CC cell proliferation, invasion and migration abilities through the regulation of the AKT/mTOR pathway and the epithelial-to-mesenchymal transition (EMT) progress. Moreover, the luciferase reporter assay indicated that six1 was one functional target for miR-23b in CC cells, indicating that the inhibitory functions of miR-23b in CC cells were partially regulated by six1. Moreover, miR-23b restoration could prominently repress tumor growth in vivo. CONCLUSIONS The TLR4-MyD88-JNK signaling pathway can facilitate the inflammatory response in ICH rats, thereby promoting the neuronal apoptosis.
