Abstract
NKX2-5 is a member of the homeobox-containing transcription factors critical in regulating tissue differentiation in development. Here, we report a role for NKX2-5 in vascular smooth muscle cell phenotypic modulation in vitro and in vascular remodelling in vivo. NKX2-5 is up-regulated in scleroderma (SSc) patients with pulmonary arterial hypertension. Suppression of NKX2-5 expression in smooth muscle cells, halted vascular smooth muscle proliferation and migration, enhanced contractility and blocked the expression of the extracellular matrix genes. Conversely, overexpression of NKX2-5 suppressed the expression of contractile genes (ACTA2, TAGLN, CNN1) and enhanced the expression of matrix genes (COL1) in vascular smooth muscle cells. In vivo, conditional deletion of NKX2-5 attenuated blood vessel remodelling and halted the progression to hypertension in the mouse chronic hypoxia mouse model. This study revealed that signals related to injury such as serum and low confluence, which induce NKX2-5 expression in cultured cells, is potentiated by TGFβ and further enhanced by hypoxia. The effect of TGFβ was sensitive to ERK5 and PI3K inhibition. Our data suggest a pivotal role for NKX2-5 in the phenotypic modulation of smooth muscle cells during pathological vascular remodelling and provide proof of concept for therapeutic targeting of NKX2-5 in vasculopathies.

Abstract
OBJECTIVE To explore the impact of diabetes on collateral circulation (CC) development in patients with chronic total coronary occlusion (CTO) and the underlying regulatory mechanism. METHODS This study was conducted among 87 patients with coronary heart disease (CHD), who had CTO in at least one vessel as confirmed by coronary angiography. Among them 42 patients were found to have a low CC level (Cohen-Rentrop grades 0-1) and 45 had a high CC level (grades 2-3). In the 39 patients with comorbid diabetes mellitus and 48 non-diabetic patients, insulin resistance (IR) levels were compared between the subgroups with different CC levels. The steady-state mode evaluation method was employed for calculating the homeostatic model assessment for insulin resistance index (HOMA-IR) using a mathematical model. During the interventional procedures, collateral and peripheral blood samples were collected from 22 patients for comparison of the metabolites using non-targeted metabolomics analysis. RESULTS NT-proBNP levels and LVEF differed significantly between the patients with different CC levels (P<0.05). In non-diabetic patients, HOMA-IR was higher in low CC level group than in high CC level groups. Compared with the non-diabetic patients, the diabetic patients showed 63 upregulated and 48 downregulated metabolites in the collateral blood and 23 upregulated and 14 downregulated metabolites in the peripheral blood. The differential metabolites in the collateral blood were involved in aromatic compound degradation, fatty acid biosynthesis, and steroid degradation pathways; those in the peripheral blood were related with pentose phosphate metabolism, bacterial chemotaxis, hexanoyl-CoA degradation, glycerophospholipid metabolism, and lysine degradation pathways. CONCLUSION The non-diabetic patients with a low level of CC had significant insulin resistance. The degradation pathways of aromatic compounds, fatty acid biosynthesis, and steroid degradation are closely correlated with the development of CC.

Abstract
INTRODUCTION Colonocyte oxidation of bacterial-derived butyrate has been reported to maintain synergistic obligate anaerobe populations by reducing colonocyte oxygen levels; however, it is not known whether this process is disrupted during the progression of type 2 diabetes. Our aim was to determine whether diabetes influences colonocyte oxygen levels in the University of California Davis type 2 diabetes mellitus (UCD-T2DM) rat model. RESEARCH DESIGN AND METHODS Age-matched male UCD-T2DM rats (174±4 days) prior to the onset of diabetes (PD, n=15), within 1 month post-onset (RD, n=12), and 3 months post-onset (D3M, n=12) were included in this study. Rats were administered an intraperitoneal injection of pimonidazole (60 mg/kg body weight) 1 hour prior to euthanasia and tissue collection to estimate colonic oxygen levels. Colon tissue was fixed in 10% formalin, embedded in paraffin, and processed for immunohistochemical detection of pimonidazole. The colonic microbiome was assessed by 16S gene rRNA amplicon sequencing and content of short-chain fatty acids was measured by liquid chromatography-mass spectrometry. RESULTS HbA1c % increased linearly across the PD (5.9±0.1), RD (7.6±0.4), and D3M (11.5±0.6) groups, confirming the progression of diabetes in this cohort. D3M rats had a 2.5% increase in known facultative anaerobes, Escherichia-Shigella, and Streptococcus (false discovery rate <0.05) genera in colon contents. The intensity of pimonidazole staining of colonic epithelia did not differ across groups (p=0.37). Colon content concentrations of acetate and propionate also did not differ across UCD-T2DM groups; however, colonic butyric acid levels were higher in D3M rats relative to PD rats (p<0.01). CONCLUSIONS The advancement of diabetes in UCD-T2DM rats was associated with an increase in facultative anaerobes; however, this was not explained by changes in colonocyte oxygen levels. The mechanisms underlying shifts in gut microbe populations associated with the progression of diabetes in the UCD-T2DM rat model remain to be identified.

Abstract
Pine wood nematode (PWN) disease is one of the major disasters in forests of southern China, causing substantial forest resources and ecological and economic losses. Based on field surveys and WFV image data from the GF-1 satellite, we constructed a spatial identification model of PWN disease with the random forest model to explore the relative influences of topography, human activities and stand factors on the occurrence of diseases and predict their spatial distribution. We then used the spatial autocorrelation analysis to assess the distribution characteristics of PWN disease at the regional scale. The results showed that the random forest model constructed in this study was effective in identifying pine nematode diseases (AUC value=0.99, overall accuracy=0.96). The norma-lized difference greenness index (NDGI), the distance to the highway, and normalized vegetation index (NDVI) were important factors in explaining the spatial variations of PWN disease occurrence. There was a positive spatial correlation in the occurrence of PWN disease (not randomly distributed but with obvious spatial aggregation characteristics). The high occurrence areas of pine wood nematode disease concentrated in Chitu Township, Zhufang Township and Shibatang Township, low occurrence areas concentrated in the vicinity of Rongjiang Street. The areas far away from the highway, low in elevation, and close to county roads were suffered to PWN disease. The results could serve the regional monitoring of pine nematode disease occurrence and provide practical guidance for PWN disease management.

Abstract
Exploring the vegetation carbon cycle and the factors influencing vegetation carbon sequestration in areas with complex plateau-basin topography and fragile ecosystems is crucial. In this study, spatial and temporal characteristics of carbon sequestration by vegetation in Sichuan and Chongqing from 2010 to 2020 and the influencing factors were investigated through simulations of net primary productivity (NPP) using the modified Carnegie-Ames-Stanford approach (CASA) and the Thornthwaite Memorial (TM) model and using chemical equations of photochemical reactions. The results indicated that: The spatial distribution of carbon sequestration capacity (CSC) trends showed an increase in the east (the most prominent increased trend along the mountainous areas of the basin) and a decrease in the west (western Sichuan plateau). Differences exist in the impact factors of CSC in different regions. In the basin margins and mountainous areas, where the proportion of forests was high, a combination of climate change and human activities contributed to the increase in CSC. The relatively warm and humid meteorological conditions in the hinterland of the basin were more conducive to the increase in CSC, and climate change also affected the region more significantly. In contrast, in the relatively high altitude of western Sichuan, controlled human activities were the key to improving CSC. The results of the study contribute to the understanding of the basic theory of vegetation carbon cycle in areas with complex plateau-basin topography and fragile ecosystems, as well as to provide suggestions for ecological shelter construction and ecological restoration in the upper Yangtze River.

Abstract
While exercise (EX) during pregnancy is beneficial for both mother and child, little is known about the mechanisms by which maternal exercise mediates changes in utero. Six-week-old female C57BL/6 mice were divided into two groups: with (exercise, EX; N = 7) or without (sedentary, SED; N = 8) access to voluntary running wheels. EX was provided via 24 h access to wheels for 10 weeks prior to conception until late pregnancy (18.5 days post coitum). Sex-stratified placentas and fetal livers were collected. Microarray analysis of SED and EX placentas revealed that EX affected gene transcript expression of 283 and 661 transcripts in male and female placentas, respectively (±1.4-fold, p < 0.05). Gene Set Enrichment and Ingenuity Pathway Analyses of male placentas showed that EX led to inhibition of signaling pathways, biological functions, and down-regulation of transcripts related to lipid and steroid metabolism, while EX in female placentas led to activation of pathways, biological functions, and gene expression related to muscle growth, brain, vascular development, and growth factors. Overall, our results suggest that the effects of maternal EX on the placenta and presumably on the offspring are sexually dimorphic.

Abstract
The prothoracicotropic hormone (Ptth) is well-known for its important role in controlling insect developmental timing and body size by promoting the biosynthesis and release of ecdysone. However, the role of Ptth in adult physiology is largely unexplored. Here we show that Ptth null mutants (both males and females) show extended lifespan and healthspan, and exhibit increased resistance to oxidative stress. Transcriptomic analysis reveals that age-dependent upregulation of innate immunity pathway is attenuated by Ptth mutants. Intriguingly, we find that Ptth regulates the innate immunity pathway, specifically in fly oenocytes, the homology of mammalian hepatocytes. We further show that oenocyte-specific overexpression of Relish shortens the lifespan, while oenocyte-specific downregulation of ecdysone signaling extends lifespan. Consistently, knocking down torso, the receptor of Ptth in the prothoracic gland also promotes longevity of the flies. Thus, our data reveal a novel function of the insect hormone Ptth in longevity regulation and innate immunity in adult Drosophila.

Abstract
OBJECTIVE To verify whether miR-150-5p modulates the development of renal fibrosis and its mechanism. METHODS Transforming growth factor (TGF)-β1 was implemented on HK-2 cells to construct a renal fibrosis in vitro model. Inhibition of autophagy was performed on HK-2 cells by treating with 3-methyladenine (3-MA, an inhibitor of autophagy). HK-2 cells experienced transfection by miR-150-5p mimics/inhibitor and pcDNA-β-catenin plasmids, and the negative controls. Dual luciferase reporter gene assay was applied to validate the relationship between miR-150-5p and β-catenin. Cell apoptosis exploration was implemented by flow cytometry assay. The level detection of CoII, α-SMA, miR-150-5p and β-catenin was executed by real-time quantitative reverse transcription-polymerase chain reaction. The expression of CoII, α-SMA, LC3I, LC3II, Bax, Cleaved Caspase 3, Beclin 1, Bcl-2 and β-catenin proteins was monitored by western blot. RESULTS Autophagy was inhibited in TGF-β1-induced HK-2 cells. MiR-150-5p alleviated fibrosis, enhanced autophagy, and inhibited apoptosis in TGF-β1-induced HK-2 cells. β-catenin was a target of miR-150-5p. Autophagy inhibition or β-catenin partially counteracted miR-150-5p effect on TGF-β1-induced fibrosis in HK-2 cells. CONCLUSIONS MiR-150-5p alleviates renal tubular epithelial cell fibrosis by activating autophagy via β-catenin signaling.

Abstract
The mammalian target of rapamycin (mTOR) is one of the most important signaling pathways that regulate nutrient sensing, cell growth, metabolism, and aging. The mTOR pathway, particularly mTOR complex 1 (mTORC1), has been shown to control aging, lifespan, and healthspan through the regulation of protein synthesis, autophagy, mitochondrial function, and metabolic health. The mTOR pathway also plays critical roles in the heart, from cardiac development, growth and maturation, and maintenance of cardiac homeostasis. Hyperactivation of mTORC1 signaling is well documented in aging and many age-related pathologies, including age-related cardiac dysfunction and heart failure. Suppression of mTORC1 by calorie restriction or rapamycin not only extends lifespan but also restores youthful phenotypes in the heart. In this article, we review model organisms of cardiac aging and highlight recent advances in the impact of the mTORC1 pathway on organismal and cardiac aging, particularly in Drosophila and mice. We focus on the downstream signaling pathways S6 kinase and 4EBP1, which regulates protein synthesis, as well as ULK1 and its related pathway that regulates autophagy. The interaction with mTOR complex 2 (mTORC2) and its potential role in cardiac aging are also discussed.

Abstract
A sensitive and rapid ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was hereby developed for the determination of seven components, namely, glycyrrhizic acid, glycyrrhetinic acid, dehydrotumulosic acid, isoliquiritin, liquiritin, atractylenolide III, and cinnamic acid, in the plasma of rats after the oral administration of Ling-Gui-Zhu-Gan decoction (LGZGD). Besides, this very method was methodologically validated for specificity, linearity, inter-day and intra-day precision, accuracy, matrix effect, extraction recovery, and stability. It was also successfully used for the first time to compare the pharmacokinetic characteristics of the seven components after oral administration of LGZGD to normal rats and non-alcoholic fatty liver disease (NAFLD) rats. The results indicated significant differences between the pharmacokinetic characteristics of normal and NAFLD rats. To further reveal the different pharmacokinetic behaviors, the expressions of enzymes and transporters in the liver of normal and NAFLD rats were detected using UPLC-MS/MS. In the NAFLD rats, UDP-glucuronosyltransferase 1-1 (UGT1A1) and nine transporters were significantly inhibited and a positive correlation was observed between them and the AUC of the major components. The present results indicate that the pharmacokinetic differences between the normal and NAFLD rats might be attributed to the significant lower expression levels of both the metabolic enzyme UGT1A1 and nine transporter proteins in the NAFLD rats than in the normal rats. Meanwhile, UGT1A1 and the nine transporter proteins might be used as potential biomarkers to assess the ameliorative effect of LGZGD on NAFLD, which could provide useful information to guide the clinical application of LGZGD.

Abstract
Background Our previous studies have identified CA916798 as a chemotherapy resistance-associated gene in lung cancer. However, the histopathological relevance and biological function of CA916798 in lung adenocarcinoma (LUAD) remains to be delineated. In this study, we further investigated and explored the clinical and biological significance of CA916798 in LUAD. Methods The relationship between CA916798 and clinical features of LUAD was analyzed by tissue array and online database. CCK8 and flow cytometry were used to measure cell proliferation and cell cycle of LUAD after knockdown of CA916798 gene. qRT-PCR and western blotting were used to detect the changes of cell cycle-related genes after knockdown or overexpression of CA916798. The tumorigenesis of LUAD cells was evaluated with or without engineering manipulation of CA916798 gene expression. Response to Gefitinib was evaluated using LUAD cells with forced expression or knockdown of CA916798. Results The analysis on LUAD samples showed that high expression of CA916798 was tightly correlated with pathological progression and poor prognosis of LUAD patients. A critical methylation site in promoter region of CA916798 gene was identified to be related with CA916798 gene expression. Forced expression of CA916798 relieved the inhibitory effects of WEE1 on CDK1 and facilitated cell cycle progression from G2 phase to M phase. However, knockdown of CA916798 enhanced WEE1 function and resulted in G2/M phase arrest. Consistently, chemical suppression of CDK1 dramatically inhibited G2/M phase transition in LUAD cells with high expression of CA916798. Finally, we found that CA916798 was highly expressed in Gefitinib-resistant LUAD cells. Exogenous expression of CA916798 was sufficient to endow Gefitinib resistance with tumor cells, but interference of CA916798 expression largely rescued response of tumor cells to Gefitinib. Conclusions CA916798 played oncogenic roles and was correlated with the development of Gefitinib resistance in LUAD cells. Therefore, CA916798 could be considered as a promising prognostic marker and a therapeutic target for LUAD.

Abstract
While the ongoing Russia-Ukraine war threatens global nutrition security, the magnitude and extent of its impact remain underexamined. Here we show that, with the lowest level of war duration, severity, sanction, and countries involved, the direct and indirect impacts of the war and sanctions could newly place 67.3 million people (roughly equals the total population of France) in undernourishment and 316.7 million people (roughly equals the total population of Bangladesh and Russia) suffering from extreme national food insecurity. Approximately 95% of the affected population are from developing countries, highlighting the vulnerability of food supply in these countries. Both the undernourished population and its inequality across countries will substantially grow, if war duration and severity increase. If the war is prolonged to early 2024, future agricultural growth cannot fully offset the negative impacts, and global hunger will still very likely exacerbate. We conclude that targeted measures should be placed in developing countries and their vulnerable populations to reconstruct a just, healthy, and environmentally sustainable food system.

Abstract
Multiple mycotoxins contamination in foods and feeds threatens human and animal health after they accumulate in the food chain, producing various toxic effects. The common mycotoxins contaimination in feeds are zearalenone (ZEN), deoxynivalenol (DON), and aflatoxin B1 (AFB1), but the effects of their co-exposure on the jejunum are not well understood. Lycopene (LYC) has been reported to have antioxidant activity that alleviates jejunal damage. In this study, we investigated the possible role of LYC as a treatment to mitigate the combined effects of ZEN, DON, and AFB1 on the jejunum of mice. Eighty male specific-pathogen-free ICR mice were randomly allocated to treatments with LYC (10 mg kg-1) and/or ZEN + DON + AFB1 (10 mg kg-1 ZEN, 1 mg kg-1 DON, and 0.5 mg kg-1 AFB1). The results indicated that LYC alleviated ZEN + DON + AFB1-induced jejunal injury by ameliorating the jejunal structural injury and increasing the villus height/crypt depth ratio and the levels of tight junction proteins (zonula occludens 1 [ZO1], occludin1 and claudin1) in the mouse jejunum. LYC also inhibited the oxidative stress induced by co-exposure to ZEN, DON, and AFB1 via reducing the levels of reactive oxygen species (ROS) and malondialdehyde (MDA) and enhancing the total antioxidant capacity (T-AOC). LYC also alleviated jejunal mitochondrial damage in the ZEN + DON + AFB1-affected mice, evident as an increase in mitochondrial fission 1 (Fis1) transcription and a reduction in mitochondrial mitofusin 1 (Mfn1) and Mfn2 transcription. Co-exposure to ZEN, DON, and AFB1 also significantly increased the transcription of ferroptosis-related genes (transferrin receptor 1 (Tfr1), ferritin heavy chain 1 [Fth1], solute carrier family 3 member 2 [Slc3a2], and glutathione peroxidase 4 [Gpx4]), TFR1 and Fe2+ concentration. Notably, LYC potentially alleviated ZEN + DON + AFB1-induced jejunal ferroptosis. These results demonstrate that LYC alleviates ZEN + DON + AFB1-induced jejunal toxicity by inhibiting oxidative stress-mediated ferroptosis and mitochondrial damage in mice.

Abstract
Rationale: Around 10%-20% patients with glioblastoma (GBM) are diagnosed with more than one tumor lesions or multifocal GBM (mGBM). However, the understanding on genetic, DNA methylomic, and transcriptomic characteristics of mGBM is still limited. Methods: In this study, we collected nine tumor foci from three mGBM patients followed by whole genome sequencing, whole genome bisulfite sequencing, RNA sequencing, and immunohistochemistry. The data were further examined using public GBM databases and GBM cell line. Results: Analysis on genetic data confirmed common features of GBM, including gain of chr.7 and loss of chr.10, loss of critical tumor suppressors, high frequency of PDGFA and EGFR amplification. Through profiling DNA methylome of individual tumor foci, we found that promoter methylation status of genes involved in detection of chemical stimulus, immune response, and Hippo/YAP1 pathway was significantly changed in mGBM. Although both CNV and promoter methylation alteration were involved in heterogeneity of different tumor foci from same patients, more CNV events than promoter hypomethylation events were shared by different tumor foci, implying CNV were relatively earlier than promoter methylation alteration during evolution of different tumor foci from same mGBM. Moreover, different tumor foci from same mGBM assumed different molecular subtypes and mesenchymal subtype was prevalent in mGBM, which might explain the worse prognosis of mGBM than single GBM. Interestingly, we noticed that LIF and CCL2 was tightly correlated with mesenchymal subtype tumor focus in mGBM and predicted poor survival of GBM patients. Treatment with LIF and CCL2 produced mesenchymal-like transcriptome in GBM cells. Conclusions: Together, our work herein comprehensively profiled multi-omics features of mGBM and emphasized that components of extracellular microenvironment, such as LIF and CCL2, contributed to the evolution and prognosis of tumor foci in mGBM patients.

Abstract
Lung cancer is the leading cause of cancer death worldwide. Cisplatin is the major DNA-damaging anticancer drug that cross-links the DNA in cancer cells, but many patients inevitably develop resistance with treatment. Identification of a cisplatin sensitizer might postpone or even reverse the development of cisplatin resistance. Halofuginone (HF), a natural small molecule isolated from Dichroa febrifuga, has been found to play an antitumor role. In this study, we found that HF inhibited the proliferation, induced G0/G1 phase arrest, and promoted apoptosis in lung cancer cells in a dose-dependent manner. To explore the underlying mechanism of this antitumor effect of halofuginone, we performed RNA sequencing to profile transcriptomes of NSCLC cells treated with or without halofuginone. Gene expression profiling and KEGG analysis indicated that PI3K/AKT and MAPK signaling pathways were top-ranked pathways affected by halofuginone. Moreover, combination of cisplatin and HF revealed that HF could sensitize the cisplatin-resistant patient-derived lung cancer organoids and lung cancer cells to cisplatin treatment. Taken together, this study identified HF as a cisplatin sensitizer and a dual pathway inhibitor, which might provide a new strategy to improve prognosis of patients with cisplatin-resistant lung cancer.

Abstract
Deterioration in glucose homeostasis has been associated with intestinal dysbiosis, but it is not known how metabolic dysregulation alters the gastrointestinal environment. We investigated how the progression of diabetes alters ileal and colonic epithelial mucosal structure, microbial abundance, and transcript expression in the University of California Davis Type 2 Diabetes Mellitus (UCD-T2DM) rat model. Male UCD-T2DM rats (age ~170 days) were included if <1-month (n = 6, D1M) or 3-month (n = 6, D3M) post-onset of diabetes. Younger nondiabetic UCD-T2DM rats were included as a nondiabetic comparison (n = 6, ND, age ~70 days). Ileum villi height/crypt depths and colon crypt depths were assessed by histology. Microbial abundance of colon content was measured with 16S rRNA sequencing. Ileum and colon transcriptional abundances were analyzed using RNA sequencing. Ileum villi height and crypt depth were greater in D3M rats compared to ND. Colon crypt depth was greatest in D3M rats compared to both ND and D1M rats. Colon abundances of Akkermansia and Muribaculaceae were lower in D3M rats relative to D1M, while Oscillospirales, Phascolarctobacterium, and an unidentified genus of Lachnospiraceae were higher. Only two transcripts were altered by diabetes advancement within the colon; however, 2039 ileal transcripts were altered. Only colonic abundances of Sptlc3, Enpp7, Slc7a15, and Kctd14 had more than twofold changes between D1M and D3M rats. The advancement of diabetes in the UCD-T2DM rat results in a trophic effect on the mucosal epithelia and was associated with regulation of gastrointestinal tract RNA expression, which appears more pronounced in the ileum relative to the colon.

Abstract
OBJECTIVE To detect plasma levels of receptor-interacting protein kinase 1 (RIP1), RIP3 and mixed lineage kinase domain-like protein (MLKL) in patients with chronic heart failure and explore the expression pattern of programmed necrosis signaling pathway RIP1/RIP3-MLKL in the progression of heart failure. METHODS The patients with chronic heart failure (NYHA class Ⅱ-Ⅳ) admitted in our hospital between February, 2020 and March, 2021 were prospectively enrolled in this study, with 21 healthy volunteers as the control group. The enrolled patients included 20 with grade Ⅱ, 33 with grade Ⅲ, and 43 with grade Ⅳ cardiac function. Fasting venous blood was collected from all the participants for detecting plasma levels of RIP1, RIP3, and MLKL and protein expressions of RIP1/RIP3-MLKL pathway using enzyme-linked immunosorbent assay (ELISA) and Western blotting. The patients with grade Ⅳ cardiac function were followed up for 5 months to evaluate the clinical prognostic indicators. RESULTS Compared with the healthy volunteers, the patients with grade Ⅱ, Ⅲ and Ⅳ cardiac function had significantly increased plasma levels of RIP1, RIP3, and MLKL (P < 0.01), and their levels were significantly higher in grade Ⅲ/Ⅳ patients than in those with grade Ⅱ cardiac function (P < 0.01); the plasma levels of RIP1 and MLKL were significantly higher in grade Ⅳ patients than in grade Ⅲ patients (P < 0.05). The results of Western blotting also showed increased expressions of the proteins in the RIP1/RIP3-MLKL pathway in patients with heart failure. Pearson correlation analysis suggested that in patients with heart failure, the expression levels of RIP1, RIP3, and MLKL were positively correlated with SCR, AST, LVEDD and NT-proBNP (P < 0.05). Follow-up study of the patients with grade Ⅳ cardiac function showed that higher expression levels of RIP1/RIP3-MLKL were associated with a poorer prognosis of the patients. CONCLUSION The expressions of RIP1, RIP3 and MLKL are significantly upregulated in patients with heart failure in positive correlation with the severity of the disease condition, and the activation of the RIP1/RIP3-MLKL signaling pathway may contribute to the occurrence, development and prognosis of chronic heart failure.

Abstract
OBJECTIVE To investigate the molecular mechanism of quercetin in the treatment of heart failure (HF) based on network pharmacology and molecular docking. METHODS Quercetin and HF-related targets were obtained using TCMSP, PharmMapper, CTD and GeneCards databases, and quercetin-HF intersection targets were obtained through the online website Venn; the protein interaction network was constructed and imported into Cytoscape 3.7.2 to identify the core targets of quercetin in the treatment of HF.GO and KEGG pathway enrichment analyses were performed using R package, and molecular docking was performed using Auto Dock Vina.The protein levels of AKT1, phospho-AKT(Ser473), eNOS, MMP9, and caspase-3 in quercetin-treated HF cell models were detected using protein immunoblotting. RESULTS We identified 80 quercetin-HF intersectional targets (AKT1, CASP3, MAPK1, MMP9, and MAPK8) and 5 core targets of quercetin for treatment of HF.GO analysis suggested that the therapeutic effect of quercetin for HF was mediated mainly by such biological processes as responses to peptide hormones, phosphatidylinositol-mediated signalling, responses to lipopolysaccharides, responses to molecules of bacterial origin and regulation of inflammatory responses.KEGG pathway enrichment analysis identified lipid and atherosclerosis pathway, proteoglycans in cancer, PI3K-AKT signaling pathway, diabetic cardiomyopathy and MAPK signaling pathway as the most significantly enriched signaling pathways.Molecular docking showed a good binding activity of quercetin to the 5 core targets.The results of protein immunoblotting showed that 100 μmol/L quercetin significantly reduced AKT1, phospho-AKT (Ser473), eNOS, MMP9 and caspase-3 levels in the cell models of HF (P < 0.01). CONCLUSION Quercetin improves the pathological changes in HF possibly by regulating the AKT1-eNOS-MMP9 pathway to inhibit cell apoptosis.

Abstract
In recent years, China's air quality has been improving, and the concentration of atmospheric particulate matter has decreased significantly. In this study, the pollution characteristics and trends of two typical representative cities (Beijing and Chengdu) were analyzed. The geographical locations, pollution emissions, and meteorological diffusion conditions of the two cities were compared, to evaluate the relative contribution of meteorological conditions and pollution reduction regulations in decreasing fine particulate matter (PM2.5) concentrations. The results showed that the number of heavily polluted days and pollution episodes in Beijing and Chengdu decreased significantly from 2013 to 2018, and the concentration of SO2 and PM2.5 decreased substantially. Compared to 2013, SO2 concentration in Beijing and Chengdu has decreased by 77.8% and 70.9%, whereas PM2.5 concentration has decreased by 42.7% and 48.5%, respectively. The largest reduction appeared in winter, when PM2.5 decreased at an annual rate of 13.5 μg ·m-3 for Beijing and 14.1 μg ·m-3 for Chengdu. During the study period, the wind speed in Chengdu was less than that in Beijing, temperature was approximately 3℃ higher, and static wind in winter was more frequent. A significantly lower mixed-layer height, atmospheric capacity index, and ventilation coefficient in Chengdu resulted in more unfavorable atmospheric diffusion conditions. The static and stable weather index and the environmental meteorological index (EMI) also showed that the atmospheric diffusion conditions were better in Beijing than in Chengdu. The EMI of the two cities showed a decreasing trend during the study period, and the decline in EMI in Chengdu was the most significant in 2018, indicating an evident improvement in meteorological conditions. In 2018, emission reductions are estimated to have contributed 33.5% and 24% to the decrease in PM2.5 in Beijing and Chengdu, respectively, and meteorological conditions contributed 7.2% and 11.1% to the reduction in these two cities. In winter, emission reductions respectively contributed 31.7% and 32.5% to reduction in Beijing and Chengdu, while meteorological conditions made a larger contribution.

Abstract
To develop excellent photoelectronic and photovoltaic devices, a semiconductor with high photoelectron production efficiency and broad band absorption is urgently required. In this article, novel II-type PbSe/ZnSe hetero-nanobelts with enhanced near-infrared absorption have been synthesized via a facile strategy of a partial cation-exchange reaction and thermal treatment. Derived from ZnSe·0.5N2H4nanobelts as templates, the belt-like morphology was preserved. Due to the mismatch of the crystal type and parameters between PbSe and ZnSe, the formed PbSe in the form of nanoparticles were separated out and decorated on the nanobelts. Furthermore, the composition ratio of Pb/Zn can be tuned through manipulating the adding amount of Pb2+cations, the reaction temperature and time. The ultraviolet-visible-infrared diffuse spectra measurements suggest that the as-prepared PbSe/ZnSe hetero-nanobelts exhibited a broad band absorption from 300 to 1000 nm. In addition, they demonstrated excellent photoresponsivity in the same wavelength region and displayed a peak at approximately 840 nm. Finally, the enhanced photoelectronic sensing mechanism was discussed.

Abstract
PURPOSE This paper aims to observe the expressions of VEGF and MMP-2 in patients with nasopharyngeal carcinoma treated by nimotuzumab combined with cisplatin. METHODS Altogether, 104 patients with nasopharyngeal carcinoma treated in our hospital from April 2014 to August 2016 were selected as research subjects. Among them, 50 patients treated with cisplatin were divided into a control group and 54 patients treated with nimotuzumab combined with cisplatin were divided into an observation group. The two groups of patients were compared in terms of efficacy after treatment and incidence of adverse reactions. Changes of serum VEGF and MMP-2 concentrations before and after treatment were detected using enzyme-linked immunosorbent assay (ELISA), and the 3-year overall survival (OS) of patients was observed. RESULTS Compared with the control group, patients in the observation group had significantly higher total remission rate (RR) (P < 0.05) and significantly lower incidence of adverse reactions (P < 0.05). Before treatment, there was no significant difference between the observation and control groups in the concentrations of VEGF and MMP-2 (P > 0.05). After treatment, the concentrations in the two groups were significantly lower than those before treatment (P < 0.05), and the concentrations in the observation group were significantly lower than those in the control group (P < 0.05). There was no significant difference in the 3-year OS between the observation and control groups (P > 0.05). CONCLUSIONS Nimotuzumab combined with cisplatin could improve the conditions of patients with nasopharyngeal carcinoma. After treatment, the expression of VEGF and MMP-2 decreased significantly. We speculated that it improves the survival rate of patients by reducing the expression of VEGF and MMP-2.

Abstract
Long non-coding RNAs (lncRNAs) are emerging as key regulators in inflammation. However, their functions and profiles in LPS-induced inflammation in pigs are largely unknown. In this study, we profiled global lncRNA and mRNA expression changes in PBMCs treated with LPS using the lncRNA-seq technique. In total 43 differentially expressed (DE) lncRNAs and 1082 DE mRNAs were identified in porcine PBMCs after LPS stimulation. Functional enrichment analysis on DE mRNAs indicated these genes were involved in inflammation-related signaling pathways, including cytokine–cytokine receptor interaction, TNF-α, NF-κB, Jak-STAT and TLR signaling pathways. In addition, co-expression network and function analysis identified the potential lncRNAs related to inflammatory response and immune response. The expressions of eight lncRNAs (ENSSSCT00000045208, ENSSSCT00000051636, ENSSSCT00000049770, ENSSSCT00000050966, ENSSSCT00000047491, ENSSSCT00000049750, ENSSSCT00000054262 and ENSSSCT00000044651) were validated in the LPS-treated PBMCs by quantitative real-time PCR (qRT-PCR). In LPS-challenged piglets, we identified that expression of three lncRNAs (ENSSSCT00000051636, ENSSSCT00000049770, and ENSSSCT00000047491) was significantly up-regulated in liver, spleen and jejunum tissues after LPS challenge, which indicated that these lncRNAs might be important regulators for inflammation. This study provides the first lncRNA and mRNA transcriptomic landscape of LPS-mediated changes in porcine PBMCs, which might provide potential insights into lncRNAs involved in regulating inflammation in pigs.

Abstract
The transcription factor foxo is a known regulator of lifespan extension and tissue homeostasis. It has been linked to the maintenance of neuronal processes across many species and has been shown to promote youthful characteristics by regulating cytoskeletal flexibility and synaptic plasticity at the neuromuscular junction (NMJ). However, the role of foxo in aging neuromuscular junction function has yet to be determined. We profiled adult Drosophila foxo- null mutant abdominal ventral longitudinal muscles and found that young mutants exhibited morphological profiles similar to those of aged wild-type flies, such as larger bouton areas and shorter terminal branches. We also observed changes to the axonal cytoskeleton and an accumulation of late endosomes in foxo null mutants and motor neuron-specific foxo knockdown flies, similar to those of aged wild-types. Motor neuron-specific overexpression of foxo can delay age-dependent changes to NMJ morphology, suggesting foxo is responsible for maintaining NMJ integrity during aging. Through genetic screening, we identify several downstream factors mediated through foxo-regulated NMJ homeostasis, including genes involved in the MAPK pathway. Interestingly, the phosphorylation of p38 was increased in the motor neuron-specific foxo knockdown flies, suggesting foxo acts as a suppressor of p38/MAPK activation. Our work reveals that foxo is a key regulator for NMJ homeostasis, and it may maintain NMJ integrity by repressing MAPK signaling.

Abstract
Urbanization in China has dramatically increased from 39.10 in 2002 to 58.52% in 2017. Studies have discussed the impacts of urbanization and its corresponding changes in consumption patterns on carbon dioxide emissions; however, little is known about their impacts on black carbon (BC). Therefore, we collected data on the BC emissions of various sectors to calculate the consumption-based BC emissions in China, and we used an input-output analysis (IOA) and structural decomposition analysis (SDA) to explore the impacts of urbanization and changes in consumption patterns on BC emissions from 2002 to 2017, focusing on sectoral BC emissions. The total BC emissions of various sectors first increased and then decreased. BC emissions increased from 1083.47 in 2002 to 2550.83 Gg in 2012. They were then reduced to 2478.63 Gg in 2017. Additionally, with the rise in the urbanization rate, household consumption BC emissions increased from 446.18 in 2002 to 1080.12 Gg in 2017. Urban consumption, rural consumption, and BC emission intensity were the three main contributing factors to household consumption BC emission changes. Transport, storage, postal, and telecommunications services (TSP); farming, forestry, animal husbandry, and fishery (FFA); and residential and other industries (RES) contributed the most to the urbanization-related BC emission increase. In particular, the TSP sector contributed the most to the BC emission increase because of the increasing TSP needs related to urbanization. Therefore, it is necessary to formulate mitigation policies for the TSP sector.

Abstract
To test the dynamic changes of the expression of genes and microRNA in the gastrocnemius muscle after LPS challenge, 36 piglets were assigned to a control group (slaughtered 0 h after saline injection) and LPS groups (slaughtered at 1 h, 2 h, 4 h, 8 h, and 12 h after LPS treatment, respectively). After LPS treatment, the mRNA expression of IL-1β, IL-6, and TNF-α reached maximal levels at 1 h, 2 h, and 1 h, respectively (P < 0.05), and mRNA expression of TLR4, NODs, muscle-specific ring finger 1, and muscle atrophy F-box peaked at 12 h (P < 0.05). Moreover, the expression of miR-122, miR-135a, and miR-370 reduced at 1 h, 1 h, and 2 h, respectively (P < 0.05), and miR-34a, miR-224, miR-132, and miR-145 reached maximum expression levels at 1 h, 1 h, 2 h, and 4 h, respectively (P < 0.05). These results suggested that mRNA expression of pro-inflammatory cytokines was elevated in the early stage, mRNA expression of genes related to TLR4 and NODs signaling pathways and protein degradation increased in the later phase, and the expression of microRNA related to muscle inflammation and protein degradation changed in the early stage after LPS injection.

Abstract
The aim of the present study was to investigate the role of microRNA (miR)-29b in the proliferation and migration of bone marrow mesenchymal stem cells (BMSCs) in rats with castration-induced osteoporosis and the relevant mechanisms. The gene expression profiling microarray technique was utilized to sequence the BMSCs with overexpressed miR-29b. The intersection of the potential targets and the genes downregulated in the sequencing were utilized for GO enrichment analysis. Gene set enrichment analysis (GSEA) was employed to analyze the effect of miR-29b on signaling pathways. Additionally, the effects of miR-29b overexpression on the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) and transforming growth factor-β (TGF-β)/Drosophila mothers against decapentaplegic protein (Smad) signaling pathways were detected via RT-qPCR assay and western blotting. The expression level of miR-29b was found to be significantly reduced in bone marrow tissues of postmenopausal osteoporosis patients and BMSCs of rats with castration-induced osteoporosis established via ovariectomy. Based on transcriptome sequencing and bioinformatics software prediction, 76 potential targets of miR-29b were obtained, which were distinctly enriched in such biological processes as cell proliferation, cell cycle, cell migration and cell adhesion. The results of CCK-8 and EdU assays showed that overexpression of miR-29b overtly promoted the proliferation of BMSCs in rats with castration-induced osteoporosis. Moreover, the Transwell assay results revealed that the overexpression of miR-29b significantly facilitated the migration of BMSCs in rats with castration-induced osteoporosis. According to RT-qPCR assay and western blotting, miR-29b activated the PI3K/AKT and TGF-β/Smad signaling pathways. miR-29b exhibited a clearly lower expression level in the bone marrow tissues of the postmenopausal osteoporosis patients and BMSCs of rats with castration-induced osteoporosis established via ovariectomy. Overexpression of miR-29b was able to enhance the proliferation and migration ability of BMSCs in rats with castration-induced osteoporosis, and such an enhancement may be correlated with the activation of the PI3K/AKT and TGF-β/Smad signaling pathways.

Abstract
OBJECTIVE To investigate the clinicopathological significance of long non-coding LINC00958 and its expression in gastric cancer (GC). PATIENTS AND METHODS A total of 200 patients with GC whose sample tissues were enrolled. Total RNA was isolated using the TRIzol method followed by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) detection of LINC00958 on mRNA level. The correlation was analyzed using Chi-square test, between the LINC00958 expression versus clinicopathological variables, including age, gender, clinical stage, tumor size, TNM classification and overall prognosis. The Kaplan-Meier survival curve was used to assess the prognostic value of LINC00958 expression, after which univariate and multivariate analysis was carried out with the COX proportional hazard analysis. RESULTS LINC00958 was shown to be dramatically elevated in GC relative to normal controls. Elevated LINC00958 significantly correlated with lymph nodes metastases, distance metastasis, peritoneal dissemination, and peritumoral tissues infiltration (p<0.05). The Kaplan-Meier survival analysis showed that up-regulated LINC00958 was markedly associated with inferior overall survival (p<0.001). In addition, multivariate analysis highlighted that LINC00958 expression was an independent prognostic factor in GC. CONCLUSIONS Our observation revealed that elevated LINC00958 was significantly associated with metastasis and was an independent prognostic factor in GC, indicating that LINC00958 can serve as a novel prognostic predictor in GC.

Abstract
Atmospheric particulate matter pollution in Zigong City in southern Sichuan is quite severe. The average concentrations of PM10 and PM2.5 from 2015 to 2018 were (95.42±9.53) μg·m-3 and (65.95±6.98) μg·m-3, with an obvious trend of decline. The concentrations of PM10 and PM2.5 in winter were much higher than in other seasons, with the highest average concentrations being(138.08±52.29) μg·m-3 and (108.50±18.05) μg·m-3 in January, respectively, whereas in summer, the average concentrations were lowest. The average ratio of PM2.5 to PM10 is 69.12%, and the ratio in winter is about 1.17 times that in summer; thus, PM2.5 is mainly responsible for the air pollution. To explore the potential sources of fine particulate matter (PM2.5) in Zigong City and the pollution contributions of different sources in different seasons, the concentration of PM2.5 in Zigong and the daily trajectory after 72 h were calculated and clustered by the combined use of a variety of potential source analysis methods and data. These methods and data included the hybrid single particle lagrangian integrated trajectory (HYSPLIT) model, global data assimilation system (GDAS) meteorological data, potential source contribution analysis (PSCF), and concentration of weight trajectory analysis (CWT). The results showed that the area near Zigong is mostly controlled by southeasterly, westerly, and northwesterly winds in all seasons, and the high PM2.5 concentration is mostly located in the low-wind-speed zone of 0-2 m·s-1. The influence of different seasons and transport routes on PM2.5 pollution in Zigong is significant. In spring, it is mainly affected by short-distance air flow from the west and north; in summer, the pollution mainly comes from the southeast air flow of short-distance transportation; in autumn, it is mainly affected by short-distance transportation air flow from Ziyang, Suining, Chongqing, and Neijiang; and in winter, it is not only affected by the surrounding cities such as Ziyang, Suining, and Neijiang but also by the long-distance transportation air flow from central Tibet. In general, the potential source area of particulate matter in Zigong City is mainly located in the border area between the west of Chongqing and the south of Sichuan. In winter, the main contribution area is at its widest, while in summer, the potential source area is smallest.

Abstract
Abstract
Objectives
Maternal diet and body composition are important determinants of offspring obesity risk, which may be mediated via changes in placental function. Here we examined the influence of maternal obesity and diet quality on the placental metabolome using untargeted metabolomics.
Methods
Placenta were collected from a longitudinal observational study in which maternal anthropometrics, body composition, dietary intake (3 d food records) and other variables were collected every trimester. Untargeted metabolomics of villous placental tissues from normal weight (NW, n = 72), overweight (OW, n = 49), and obese women (OB, n = 29) based on BMI at first trimester, were performed using GC-TOF MS. Differential metabolite features were identified using univariate comparisons (ANOVA/Mann Whitney U tests) and partial least squares discriminant analysis (PLS-DA).
Results
Principal component analysis did not reveal global shifts in the metabolome with maternal OW or OB. While no differences survived multiple testing corrections (P < 0.05), univariate analysis indicated that OW/OB subjects showed increased abundance of 2-deoxypentitol and decreases in maltotriose and 3-hydroxybutanoic acid relative to NW subjects (un-adjusted P < 0.05). Alterations in a number of non-annotated metabolites were also observed between NW, OW and OB groups. PLS-DA models predicted maternal OB status with ∼80% accuracy in held out samples. Predictive metabolites were enriched for aspartate metabolism and ammonia recycling. The global placental metabolome was significantly associated with maternal diet quality (Healthy Eating Index 2010 score averaged over pregnancy; PC1 ANOVA P < 0.01) which was characterized by differences in 138 metabolites (ANOVA, un-adjusted P < 0.05). Abundance of heptadecanoic acid and glycerol-3-galactoside increased with HEI score.
Conclusions
Maternal obesity appears to alter amino acid or protein metabolism, whereas diet quality seemed to affect metabolism of fatty acids and BCAA. These results suggest a potential shift in nutrient delivery to the offspring.

Abstract
OBJECTIVE To investigate the effect of nalmefene hydrochloride on TLR4 signaling pathway in rats with lung ischemia-reperfusion injury. MATERIALS AND METHODS Altogether 64 pure inbred male SD rats were divided into groups A, B, C, and D according to the principle of body weight similarity, with 24 rats in each group. Four groups of rats were respectively twisted on the left testis to establish unilateral testicular torsion rats. Group A was the control group, treated with normal saline, group B was the nalmefene hydrochloride high-dose group, treated with 20 μg/kg of nalmefene hydrochloride, group C was the nalmefene hydrochloride low-dose group, treated with 10 μg/kg of nalmefene hydrochloride, and group D was the sham operation group. Lung tissue was collected 60 h later. Western blotting was used to detect the expression levels of HMGB1, TLR4, CD14, and NF-κB protein, qPCR was used to detect the mRNA expression level, and enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of inflammatory factors IL-17, IL-6, and ICAM-1. RESULTS The expression levels of HMGB1, TLR4, CD14, NF-κB protein, mRNA, IL-17, IL-6, and ICAM-1 in group A were significantly higher than those in groups B, C, and D (p<0.05), while were significantly lower in group D than in groups B and C (p<0.05), and were significantly lower in group B than in group C (p<0.05). CONCLUSIONS Nalmefene hydrochloride can effectively inhibit the signal pathway of TLR4, and can effectively reduce the injury caused by lung ischemia-reperfusion. The large dose is closely related to the good effect, which is worthy of promotion.

Abstract
Age-related impairment of macroautophagy/autophagy and loss of cardiac tissue homeostasis contribute significantly to cardiovascular diseases later in life. MTOR (mechanistic target of rapamycin kinase) signaling is the most well-known regulator of autophagy, cellular homeostasis, and longevity. The MTOR signaling consists of two structurally and functionally distinct multiprotein complexes, MTORC1 and MTORC2. While MTORC1 is well characterized but the role of MTORC2 in aging and autophagy remains poorly understood. Here we identified TGFB-INHB/activin signaling as a novel upstream regulator of MTORC2 to control autophagy and cardiac health during aging. Using Drosophila heart as a model system, we show that cardiac-specific knockdown of TGFB-INHB/activin-like protein daw induces autophagy and alleviates age-related heart dysfunction, including cardiac arrhythmias and bradycardia. Interestingly, the downregulation of daw activates TORC2 signaling to regulate cardiac autophagy. Activation of TORC2 alone through overexpressing its subunit protein rictor promotes autophagic flux and preserves cardiac function with aging. In contrast, activation of TORC1 does not block autophagy induction in daw knockdown flies. Lastly, either daw knockdown or rictor overexpression in fly hearts prolongs lifespan, suggesting that manipulation of these pathways in the heart has systemic effects on longevity control. Thus, our studies discover the TGFB-INHB/activin-mediated inhibition of TORC2 as a novel mechanism for age-dependent decreases in autophagic activity and cardiac health.

Abstract
BACKGROUND Hashimoto's thyroiditis (HT) is characterized by lymphocytic infiltration of the thyroid parenchyma, which ultimately leads to tissue destruction and loss of function. Caveolin-1 (Cav-1) is an essential structural constituent of lipid rafts in the plasma membrane of cells and is reported to be significantly reduced in thyrocytes from HT patients. However, the mechanism of Cav-1 involvement in HT pathogenesis is still largely unclear. METHODS Cav-1 expression in thyroid tissues from HT patients and euthyroid nodular goiter tissues was detected by immunohistochemistry staining. Cav-1 knockdown and overexpression were constructed by lentiviral transfection in the human thyroid follicular epithelial cell (TFC) line of Nthy-ori 3-1. The mRNA expression levels of chemokines in TFCs were determined by quantitative real-time PCR (qPCR). Cav-1 and peroxisome proliferator-activated receptor gamma (PPARγ) levels were analysed by qPCR and Western blot analysis. The migration ability of peripheral blood mononuclear cells (PBMCs) was detected by the Transwell assay. RESULTS In this study, Cav-1 and PPARγ expression was reduced in the thyroid tissues from HT patients. In vitro experiments showed that the expressions of chemokine (C-C motif) ligand 5 (CCL5) and migration of PBMCs were markedly increased, while the level of PPARγ was significantly decreased after the lentivirus-mediated knockdown of Cav-1 in Nthy-ori 3-1 cells. Interestingly, pioglitazone, a PPARγ agonist, not only upregulated PPARγ and Cav-1 proteins significantly, but also effectively reversed the Cav-1-knockdown-induced upregulation of CCL5 in Nthy-ori 3-1 cells and reduced the infiltration of lymphocytes. CONCLUSION The inhibition of Cav-1 upregulated the CCL5 expression and downregulated the PPARγ expression in TFC while pioglitazone, a PPARγ agonist, reversed the detrimental consequence. This outcome might be a potential target for the treatment of lymphocyte infiltration into the thyroid gland and HT development.

Abstract
Recent evidence has shown that long noncoding RNAs (lncRNAs) play major roles in tumorigenesis and cancer progression. The cancer genome atlas program (TCGA) database was used to screen colon adenocarcinoma (COAD)-related differentially expressed lncRNAs, which revealed that lncRNA ELFN1-AS1 was highly expressed in COAD. This study aimed to explore the regulatory role of ELFN1-AS1 in COAD and construct a gene delivery system based on extracellular vesicles (EVs). We found that ELFN1-AS1 levels were obviously increased in COAD patients and COAD tumor cells. Knockdown of ELFN1-AS1 expression by siRNA inhibited COAD cell proliferation and migration. Moreover, silencing ELFN1-AS1 significantly reduced the activation of extracellular signal-regulated protein kinase (Erk), up-regulated the protein expression of E-cadherin and down-regulated vimentin. In addition, we treated human umbilical cord mesenchymal stem cells (hUCMSCs) with siRNA-ELFN1-AS1 and found that EVs from siRNA-ELFN1-AS1-treated hUCMSCs could inhibit COAD cell proliferation and migration in vitro. These findings suggested that ELFN1-AS1 could promote the progression of COAD and that hUCMSC-EVs might be an attractive vehicle for the clinical administration of lncRNA-specific siRNAs in patients with COAD.

Abstract
Caenorhabditis elegans is a well-established laboratory animal model and has been widely used in biological research. However, it is still a challenge to obtain a good amount of quality RNA from a limited number of C. elegans for gene expression studies. To address this issue, the present study has compared different conditions to preserve C. elegans for RNA extraction after the failure of an initial effort to use RNAlater-preserved worms for RNA extraction. The effects of different concentrations of proteinase K, different worm life stages, and different worm numbers on RNA extraction were also investigated. The best results were achieved under the following conditions: 1) adult worms that were either freshly prepared or quickly frozen in liquid nitrogen followed by storage at −80 °C; 2) disruption of C. elegans with proteinase K (1 mg/mL) in a lysis buffer (65 °C for 10 min) prior to extraction with Trizol agent. This method can provide a stable, rapid, and effective means to extract RNA from C. elegans with variable worm numbers from 20 to 200. RNAlater was inappropriate for preserving C. elegans for effective RNA extraction. Proteinase K was verified for lysing a limited number of C. elegans for RNA extraction.

Abstract
A combination method of ultra-performance liquid chromatography (UPLC) coupled with diode array detection has been developed for quality evaluation of Qinma prescription (QMP), based on chromatographic fingerprint technology with the similarity analysis (SA) and the quantitative analysis of 12 components by hierarchical cluster analysis (HCA). The established method has been validated by linearity, precision, repeatability, stability and recovery tests. The UPLC fingerprints with 17 common peaks of 5 QMP samples prepared by different extraction methods including water decoction extraction, water extraction-ethanol precipitation method, ethanol reflux extraction, ethanol extraction-water precipitation method and methanol ultrasonic extraction were obtained, and the SA results indicated that similarity index was greatly influenced by the large peak. The similarity index ranged from 0.816 to 0.999 basing on 17 peaks, which has been decreased to 0.683-0.999 basing on 16 peaks without the large peak of baicalin (BA). The results of simultaneous quantification of 12 components in these 5 QMP samples proved that BA, gallic acid (GA), wogonoside (WOG) and gentiopicroside (GEN) were the major ingredients in QMP with high contents >1.44 (mg/g), indicating that ethanol reflux was the most effective extraction method. Integrating fingerprint analysis, simultaneous determination and HCA, the established method is rapid, sensitive, accurate and readily applicable. All the results indicated that the combination method can control the quality of QMP and its related traditional Chinese medicinal compounds more comprehensively and scientifically.

Abstract
Abstract
Objectives
Maternal body composition during pregnancy is an important determinant of offspring obesity risk. One hypothesized mechanism linking maternal and offspring obesity is via alterations in placental gene expression and function. Here we examined the influence of early pregnancy maternal obesity on placental gene expression at term using transcriptomic approaches.
Methods
We examined placenta collected from a longitudinal observational study of mothers and infants where maternal anthropometrics, body composition, dietary intake (3 d food records) and other variables were collected every trimester in the mothers. Placentas were collected within 30 min of delivery and archived for molecular and histologic analysis. For the current analyses, transcriptomic analysis of villous placental tissues from normal weight (NW, N = 71), and overweight/obese women (OW, N = 70, based on BMI < 10 wk of pregnancy) were performed using strand-specific mRNA-seq. Data analyses were carried out using the STAR-Seqmonk-Limma pipeline.
Results
RNA-seq analysis provided quantitative information on expression of 13,831 transcripts (> 2 counts/million in 50% of samples). Assessment via principal component analysis identified significant effects of maternal BMI (in male infants), infant sex and mode of delivery on placental gene expression. Linear regression of mRNA expression with early pregnancy maternal BMI (adjusting for mode of delivery and sex) identified significant association with 230 transcripts (P < 0.05). Likewise, regression analysis of maternal body fat identified significant associations with 271 genes, with 99 genes shared in common between BMI and body fat. These transcripts were enriched for cell morphogenesis, fatty acid biosynthetic and lipid transport related pathways. Of note, expression of ABCG1 (cholesterol transporter), MMP1, CEBPα and PRKAG2 (AMPKγ2) were negatively associated with maternal BMI (P < 0.05). mRNA expression of MHC Class II antigens DRB1 and DRB5, critical in antigen presentation and immune response was increased (> 1.8-fold) in male placenta of OW women.
Conclusions
In a large cohort of well-characterized pregnant women maternal adiposity status in early pregnancy influences term placental expression of genes involved in lipid transport, metabolism and innate immune response in a sexually dimorphic manner.

Abstract
Domestic trade flourishes with economic development and the spatial separation of production and consumption. Therefore, the prosperity of trade is accompanied by the transfer of pollution from the demand side to the supply side, which could potentially worsen the environmental quality of the supply side. Despite a large number of studies on the pollution haven hypothesis in international trade, little attention has been paid to testing the hypothesis in domestic trade. Here, combining a multiregional input-output analysis and a gravity model of trade in China, we provide an empirical test to address this problem for the first time. We also assess the factors affecting the SO2 emissions embodied in trade, including population, economic development, coal consumption, distance, and environmental regulations. We found that domestic trade contributed approximate one third of the total SO2 emissions in China, and interprovincial transfers of SO2 embodied in trade were significantly determined by the population, economic development, coal consumption of the trade pairs, as well as their distance. SO2 emission mitigation policies, such as emission reduction target and sulfur dioxide control zone, has a more significant influence on the direct transfer of SO2 emission via direct bilateral trade, while their effects were largely offset by indirect trade (through third-party transfers). Our results do not support the pollution haven hypothesis existed in domestic trade in China during 2007-2012. Our paper sets an example and provides a reference for the domestic pollution transfer problem from an econometric perspective. Further attempts on testing pollution haven hypothesis in consideration of various pollutants are still needed to arrive at a robust conclusion.

Abstract
Most cellular processes descend into failure during aging. While a large collection of longevity pathways has been identified in the past decades, the mechanism for age-related decline of cellular homeostasis and organelle function remains largely unsolved. It is known that many organelles undergo structural and functional changes during normal aging, which significantly contributes to the decline of tissue function at old ages. Since recent studies have revealed an emerging role of organelles as regulatory hubs in maintaining cellular homeostasis, understanding of organelle aging will provide important insights into the cellular basis of organismal aging. Here we review current progress on the characterization of age-dependent structural and functional alterations in the more well-studied organelles, as well as the known mechanisms governing organelle aging in model organisms, with a special focus on the fruit fly Drosophila melanogaster.
