Effect of dietary supplements on Se bioavailability: A comprehensive in vitro and in vivo study.

Selenium (Se) is an essential micronutrient for animals and humans, and it is present in many different forms with different levels of bioaccessibility in food. Based on the maldistribution of Se and overall low level of Se dietary intake in China, an integrated study was conducted in this thesis to provide references for the regulation of Se nutrition. An in vitro simulation test was used to monitor the concentration effects, the impacts of dietary supplement combinations on the bioaccessibility of Se were examined in rice, and a model animal experiment (in vivo) was used to evaluate the practicability of the Se nutrition regulation scheme. The main results were as follows: the bioaccessibility of Se was effectively increased by 30 mg·d-1 VE (VE), 300 mg·d-1 VC + 300 µg·d-1 VB9 (VC+VB9) and 30 mg·d-1 VE + 300 mg·d-1 VC + 300 µg·d-1 VB9 (3IN1) (P < 0.05). The results of the healthy broiler tests showed that the 3 treatments increased the weight and Se content of the broilers, and 3IN1 had the most significant effect (P < 0.05). VC+VB9 was the best at promoting GPx activity, while 3IN1 was the best at promoting SOD activity and the inhibition of MDA content in broilers. The results suggested that VE, VC+VB9 and 3IN1 can benefit the bioavailability of Se and the antioxidant capacity of the body. The results can be used as a scientific reference for Se nutrition regulation.

Histone methylation and diabetic cardiomyopathy / 生理学报

Histone methylation is one of the key post-translational modifications that plays a critical role in various heart diseases, including diabetic cardiomyopathy. A great deal of evidence has shown that histone methylation is closely related to hyperglycemia, insulin resistance, lipid and advanced glycation end products deposition, inflammatory and oxidative stress, endoplasmic reticulum stress and cell apoptosis, and these pathological factors play an important role in the pathogenesis of diabetic cardiomyopathy. In order to provide a novel theoretical basis and potential targets for the treatment of diabetic cardiomyopathy from the perspective of epigenetics, this review discussed and elucidated the association between histone methylation and the pathogenesis of diabetic cardiomyopathy in details.

Mechanism of the role of NDUFAF4 in increasing radiation resistance of hepatocellular carcinoma by activating Wnt/β-catenin signaling pathway / 中华放射肿瘤学杂志

Objective:To analyze the association between the expression of ubiquinone oxidoreductase complex assembly factor 4 (NDUFAF4) and clinical prognosis of patients with hepatocellular carcinoma (HCC), evaluate the effect of NDUFAF4 on the radiosensitivity of human HCC cell lines, and unravel the underlying mechanism.Methods:The online database and HCC tissue samples were used to investigate the expression of NDUFAF4, and the correlation between NDUFAF4 expression level and clinical prognosis. The si-NDUFAF4 plasmid which down-regulated the expression level of NDUFAF4 was transferred into HepG2 and Huh7 cells. The radiosensitivity of HCC cell lines was detected by clone formation experiment. Nude mice were prepared for tumor-bearing experiment. The β-catenin level was detected by immunofluorescent staining. The expression levels of E-cadherin and N-cadherin proteins were determined by Western blot.Results:Bioinformatics results confirmed that NDUFAF4 was significantly up-regulated in HCC tissues, and the higher the expression level, the worse the patients' clinical prognosis ( P<0.05). The expression level of NDUFAF4 in HCC tissues was significantly higher than that in the adjacent tissues. Clone formation experiment confirmed that knockdown of NDUFAF4 significantly decreased the survival rate of HCC cells ( P<0.01). In vivo experiment showed that knockdown of NDUFAF4 could prevent the proliferation of HCC cells and down-regualte the expression levels of β-catenin and Ki-67. Knockdown of NDUFAF4 significantly down-regulated the expression level of β-catenin protein in the nucleus of HCC cell lines, suggesting that NDUFAF4 could activate the WNT/β-catenin signaling pathway. Knockdown of NDUFAF4 significantly up-regulated the expression level of E-cadherin and down-regulated that of N-cadherin. Conclusions:Knockdown of NDUFAF4 can significantly enhance the radiosensitivity of HCC cell lines by inhibiting the WNT/β-catenin signaling pathway. The expression level of NDUFAF4 is intimately correlated with clinical prognosis. NDUFAF4 can be considered as a new target for lowering the radiation resistance of HCC.

Analysis on off-label use of drugs in pediatric guidelines and consensus published by Chinese authors / 中华儿科杂志

Objective: To understand the current situation regarding pediatric off-label use of drugs recommendations in Chinese clinical practice guidelines and to make recommendations for standardized reporting format regarding off-label use of drugs for children. Methods: This cross-sectional study was carried out by systematically searching the databases for Chinese guideline consensus articles published in journals between 2018 and 2020 and extracting recommendations regarding off-label use of drugs from those articles. The essential characteristics of the included guidelines, the ranking of off-label drug types, the order of drug information, the type of off-label drug use, and the percentage of citation studies on which the recommendations were based were analyzed. Results: Among 108 studies that included Chinese off-label guidelines and consensus, 364 recommendations on pediatric off-label use of drugs were included. The Chinese Medical Association published the most, 48 out of the 108 studies (44.4%), and of those 14 studies (13.0%) were on infectious and parasitic diseases. Of the 364 recommendations on off-label use of drugs, the most commonly addressed drugs were 16 recommendations (4.4%) for cyclosporine A, 11 recommendations (3.0%) for methotrexate , and 11 recommendations (3.0%) for fentanyl. The most commonly addressed drug categories were as follows: 68 recommendations (18.6%) were immune system drugs, 66 recommendations (18.1%) were anti-infectives, and 56 recommendations (15.4%) were oncology drugs. The most commonly addressed drug information accounts were as follows: 364 recommendations (100.0%) were indications, 204 recommendations (56.0%) were dosages, and 198 recommendations (54.4%) were the route of administration. Based on the instructions approved by the Chinese Food and Drug Administration, the main forms of the off-label drug were as follows: 175 recommendations (48.1%) were unapproved indications, 127 recommendations (34.9%) were unapproved populations, and 72 recommendations (19.8%) were unapproved ages. Only 129 recommendations (35.4%) were cited, mainly including clinical guidelines (48 studies, 23.4%), reviews (22 studies, 10.7%), and pediatric randomized controlled trials (22 studies, 10.7%). Conclusions: Off-label use of drugs is commonly recommended in pediatric guidelines and consensus documents written by Chinese authors. However, the reporting of the recommendations varies widely, and the quality of the supporting evidence is poor.

Enhanced Immune Response Improves Resistance to Cadmium Stress in Triploid Crucian Carp.

Previous research has indicated that triploid crucian carp (3n fish) have preferential resistance to cadmium (Cd) compared to Carassius auratas red var. (2n fish). In this article, comparative research is further conducted between the 2n and 3n fish in terms of the immune response to Cd-induced stress. Exposure to 9 mg/L Cd for 96 h changed the hepatic function indexes remarkably in the 2n fish, but not in the 3n fish. In the serum of Cd-treated 2n fish, the levels of alanine amino transferase, aspartate aminotransferase, adenosine deaminase, and total bilirubin significantly increased, while the levels of total protein, albumin, lysozyme, and anti-superoxide anion radicals decreased demonstrating hepatotoxicity. By analysis of transcriptome profiles, many immune-related pathways were found to be involved in the response of 3n fish to the Cd-induced stress. Expression levels of the immune genes, including the interleukin genes, tumor necrosis factor super family member genes, chemokine gene, toll-like receptor gene, and inflammatory marker cyclooxygenase 2 gene were significantly enhanced in the hepatopancreas of the Cd-treated 3n fish. In contrast, the expression levels of these genes decreased in the 2n fish. This research provides a theoretical basis for polyploid fish breeding and is helpful for the ecological restoration of water due to pollution.

Role and damage mechanism of retinal pigment epithelial cells in dry ARMD / 国际眼科杂志(Guoji Yanke Zazhi)

@#Age-related macular degeneration(ARMD)is a major cause of irreversible loss of central vision in the elderly. Typical characteristics of ARMD consist of retinal pigment epithelium(RPE), degenerative changes of choroidal capillaries and vitreous warts in macular area. Clinical ARMD is divided into two subtypes: non effusive(dry or atrophic)and effusive(wet or neovascular). The occurrence of the disease is the result of the interaction of many factors, such as age, environment, heredity, smoking, oxidative stress and cardiovascular dysfunction, <i>etc</i>. In view of the important role of RPE cells in pathogenesis of ARMD, the effects and possible mechanisms of blue light, smoking, oxidative stress, lipofuscin accumulation, chronic inflammation and protein homeostasis on the onset of dry ARMD are summarized by focusing on RPE cells. This will provide new ideas to help understand and prevent the occurrence of dry ARMD.

Transferable Molecular Model of Woven Covalent Organic Framework Materials.

Two woven covalent organic framework materials (COF-505 and COF-506) have been synthesized since 2016, and the latter demonstrated the ability to take up dyes and other small molecules. This opens the door to applications such as separations, sensing, and catalysis. However, accelerating the design of future woven materials by changing the chemistry of the "threads" will require a computational model for these materials. Since no such atomic-scale model exists, we have developed a protocol for optimizing a force field for woven materials which can be used as the input to molecular dynamics simulations. Their high density and elasticity made these COFs challenging to model at a semiempirical level. Our modeling approach required simultaneous optimization of lattice parameters and elasticity using density functional theory-derived energy barriers and available experimental results. We used this force field, parameterized to fit COF-505, without change, to predict the structure of COF-506. This model allowed us to predict an anisotropy in 505's elasticity and preferred directions for diffusion which cannot be seen experimentally. The pore size distribution for 506 is dominated by small pores (80% <10 Å dia.), though 5% of the pores are up to 20 Å in diameter. We confirmed the experimental result that gases (barring helium) do not diffuse appreciably in COF-505. We validated our (unaltered) force field model to accurately predict experimental uptake data for tetrahydrofuran and methyl orange dye in COF-506. We proposed an atomic-scale mechanism by which COF-505 becomes metallated and demetallated. In addition, in advance of experimental studies, we determined the ability of 505 to incorporate other metals, such as Zn and Fe, which might be considered artificial photosynthesis agents. These predictions validate that Cu was a particularly appropriate choice of metal center for the synthesis, showcasing the ability of this model to play a role in designing woven materials a priori.

Myeloid-Derived Suppressor Cells Recruited by Chemokine (C-C Motif) Ligand 3 Promote the Progression of Breast Cancer via Phosphoinositide 3-Kinase-Protein Kinase B-Mammalian Target of Rapamycin Signaling / 한국유방암학회지

Purpose@#Numerous studies have shown that the frequency of myeloid-derived suppressor cells (MDSCs) is associated with tumor progression, metastasis, and recurrence. Chemokine (C-C motif) ligand 3 (CCL3) may be secreted by tumor cells and attract MDSCs into the tumor microenvironment. In the present study, we aimed to explore the molecular mechanisms whereby CCL3 is involved in the interaction of breast cancer cells and MDSCs. @*Methods@#The expression of CCL3 and its receptors was investigated using real-time polymerase chain reaction, western blotting, and enzyme-linked immunosorbent assay. The cell counting Kit-8, wound healing, and transwell assays were performed to study cell growth, migration, and invasion. Cell cycling, apoptosis, and the frequency of MDSCs were investigated through flow cytometry. Transwell assays were used for co-culture and chemotaxis detection. Markers of the epithelial-mesenchymal transition (EMT) were determined with western blotting. The role of CCL3 in vivo was studied via tumor xenograft experiments. @*Results@#CCL3 promoted cell proliferation, migration, invasion, and cycling, and inhibited apoptosis of breast cancer cells in vitro. Blocking CCL3 in vivo inhibited tumor growth and metastases. The frequency of MDSCs in patients with breast cancer was higher than that in healthy donors. Additionally, MDSCs might be recruited by CCL3. Co-culture with MDSCs activated the phosphoinositide 3-kinase-protein kinase B-mammalian target of rapamycin (PI3K-Akt-mTOR) pathway and promoted the EMT in breast cancer cells, and their proliferation, migration, and invasion significantly increased. These changes were not observed when breast cancer cells with CCL3 knockdown were co-cultured with MDSCs. @*Conclusion@#CCL3 promoted the growth of breast cancer cells, and MDSCs recruited by CCL3 interacted with these cells and then activated the PI3K-Akt-mTOR pathway, which led to EMT and promoted the migration and invasion of the cells.

miR-1301/TRIAP1 Axis Participates in Epirubicin-Mediated Anti-Proliferation and Pro-Apoptosis in Osteosarcoma

PURPOSE: Epirubicin is one of the most effective drugs against osteosarcoma. miR-1301 is involved in the occurrence and development of osteosarcoma. Whether miR-1301 is responsible for the chemosensitivity of osteosarcoma cells to epirubicin remains largely unknown. MATERIALS AND METHODS: U2OS and SAOS-2 cells were treated with various concentrations of epirubicin. Flow cytometry was employed to evaluate cell apoptotic rate. Cell proliferation was measured by Cell Counting Kit-8 assay. Western blot and quantitative real-time polymerase chain reaction were utilized to detect the expressions of B-cell lymphoma-2 (Bcl-2), Bcl-2 assaciated X protein (Bax), cleaved-caspase-3, cleaved-poly (ADP-ribose) polymerases (PARP1), TP53-regulated inhibitor of apoptosis 1 (TRIAP1), and microRNA-1301 (miR-1301). The relationship between miR-1301 and TRIAP1 was determined by luciferase reporter assay. RESULTS: Epirubicin inhibited proliferation in a dose-dependent manner, induced apoptosis, decreased the expression of Bcl-2, and increased the expressions of Bax, cleaved-caspase-3, and cleaved-PARP1 in osteosarcoma cells. miR-1301 was downregulated in U2OS and SAOS-2 cells. Importantly, epirubicin significantly increased the levels of miR-1301. Overexpression of miR-1301 suppressed proliferation and promoted apoptosis. Interestingly, those effects were enhanced by epirubicin. In contrast, miR-1301 depletion attenuated the epirubicin-mediated anti-osteosarcoma effect. miR-1301 negatively regulated the expression of TRIAP1 in U2OS and SAOS-2 cells. Furthermore, epirubicin inhibited the mRNA and protein levels of TRIAP1 by upregulating miR-1301 levels. Epirubicin suppressed cell proliferation by downregulating TRIAP1. CONCLUSION: miR-1301 was implicated in the chemosensitivity of osteosarcoma to epirubicin by modulating TRIAP1.

Adaptive Output Regulation of Heterogeneous Multiagent Systems Under Markovian Switching Topologies.

This paper investigates the adaptive output regulation problem for heterogeneous linear multiagent systems under randomly switching communication topologies. The switching mechanism is governed by a time-homogeneous Markov process, whose states correspond to all possible communication topologies among agents. A novel distributed adaptive cooperative controller is presented, where the dynamic compensators are utilized to estimate the exogenous signal for all the agents in mean square sense. The distributed control law is based upon the local information of agents, without using the global information of the communication topologies. Finally, illustrative examples are put forward to demonstrate the effectiveness of the given control scheme.

Effects of Cornel Iridoid Glycoside on Learning-memory Ability and Brain Pathological Changes in Vascular Dementia Rats / 中国中医药信息杂志

Objective To investigate the effects of cornel iridoid glycoside (CIG) on the learning-memory ability and pathological changes in the brain of vascular dementia (VD) rats; To discuss relevant mechanism of action. Methods SD rats were randomly divided into sham-operation group, model group, positive medicine group, CIG groups low-, medium- and high-dose groups. The animal model of VD was replicated by permanent bilateral common carotid artery occlusion (2VO) in rats. Drugs were intragastrically administered 6 h after surgery and then once a day for 3 months. Morris water maze test was used to detect spatial learning-memory ability, and recognition memory was measured by the object recognition test. Immunohistochemical staining was used to detect the neuronal survival and the expression of choline acetyltransferase (ChAT) in the brain. Results Three months after permanent 2VO operation, the model rats showed a longer escape latency in Morris water maze, a lower discrimination index in the object recognition test, and a decrease in NeuN positive neuronal survival and ChAT expression in the hippocampus and cerebral cortex. Compared with the model group, intragastric administration of CIG for 3 months shortened the escape latency in Morris water maze, elevated the discrimination index in the object recognition test, and increased the NeuN positive neuronal survival in the hippocampus and cerebral cortex and ChAT expression of 2VO rats. Conclusion CIG can improve the cognitive impairment of VD model rats through protecting neurons and promoting ChAT expression.

[Community characteristics in Qingyihe River basin of Xuchang section and their relationships with environmental factors.] / æ¸ æ½©æ²³(许昌段)æµåŸŸç”Ÿç‰©ç¾¤è½ç‰¹å¾åŠå ¶ä¸ŽçŽ¯å¢ƒå› å­çš„å ³ç³».

We took Xuchang section of Qingyihe River Basin as study object to explore biodiversity in Qingyihe River. On the basis of field survey and in-laboratory analysis, community characteristics of aquatic macrophytes, riparian zone plants and macrobenthos, with environmental characteristics of water and surface sediment were investigated. Results showed that a total of 12 species of aquatic macrophytes, 66 species of riparian zone plants, and 10 species of macrobenthos were found. The communities varied sharply with the changes in the environmental factors, such as NH4+-N, TN, TP in the water and oxidation-reduction potential (ORP), TP, Cd, Hg, Zn in the surface sediment. The CCA ordination results indicated that COD, temperature, pH, DO, TP in the water were key factors influencing aquatic macrophytes, while ORP, pH in the water and Ni, Hg, TOC, Pb, Cd in the surface sediment were key factors for riparian zone plants. pH, temperature, ORP, As, Pb, Ni in the surface sediment and temperature in the water were the key factors influencing community characteristic of macrobenthos. In Qingyihe River basin of Xuchang section, the water had been polluted and the biodiversity of communities was low, so it is urgent to treat wastewater along the river as well as protect and recover communities.

[Water purification of four aquatic plant species with the presence of iron-carbon interior electrolytic substrates.] / 铁-ç¢³å† ç”µè§£è´¨ä¸‹4种水生植物的净水效果.

To compare water purification of common aquatic plants in wetland ecosystem, four common aquatic plant species (Eichhornia crassipes, Nymphaea tetragona, Acorus calamus and Phragmites australis) were used as study species. The effect of aquatic plants on the change of sewage ammonium nitrogen, COD, TP content during different experimental time (1-5 d) with the presence of iron-carbon interior electrolytic substrates were analyzed in small scale experimental apparatus. The results showed that single and combined aquatic plants could effectively remove ammonium nitrogen, COD, TP from the sewage compared with the no-plant control group, but the efficiencies were significantly different among the different species. Ammonium nitrogen removal up to 100% was achieved with E. crassipes in two days, and A. calamus in three days. Each plant combination performed well on ammonium nitrogen removal. Concentration of the sewage COD approached zero with E. crassipes in three days, A. calamus performed secondly. The concentration of COD in combination of E. crassipes and A. calamus water decreased by 85.1% to a minimum of 4.33 mg·L-1. The concentration of TP was the lowest with E. crassipes in four days, and second with P. australis. The lowest concentration of TP was found with the combination of E. crassipes and A. calamusin two days. The combination effect of interior electrolyte and plant was better than that of pure interior electrolyte on the purification of sewage. Plant configuration should be optimized according to the level of pollutants.

Head to Head Comparison of Two Point-of-care Platelet Function Tests Used for Assessment of On-clopidogrel Platelet Reactivity in Chinese Acute Myocardial Infarction Patients Undergoing Percutaneous Coronary Intervention / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Platelet function tests are widely used in clinical practice to guide personalized antiplatelet therapy. In China, the thromboelastography (TEG) test has been well accepted in clinics, whereas VerifyNow, mainly used for scientific research, has not been used in routine clinical practice. The aim of the current study was to compare these two point-of-care platelet function tests and to analyze the consistency between the two tests for evaluating on-clopidogrel platelet reactivity in Chinese acute myocardial infarction patients undergoing percutaneous coronary intervention (PCI).</p><p><b>METHODS</b>A total of 184 patients admitted to Fuwai Hospital between August 2014 and May 2015 were enrolled in the study. On-clopidogrel platelet reactivity was assessed 3 days after PCI by TEG and VerifyNow using adenosine diphosphate as an agonist. Based on the previous reports, an inhibition of platelet aggregation (IPA) <30% for TEG or a P2Y12 reaction unit (PRU) >230 for VerifyNow was defined as high on-clopidogrel platelet reactivity (HPR). An IPA >70% or a PRU <178 was defined as low on-clopidogrel platelet reactivity (LPR). Correlation and agreement between the two methods were analyzed using the Spearman correlation coefficient (r) and kappa value (κ), respectively.</p><p><b>RESULTS</b>Our results showed that VerifyNow and TEG had a moderate but significant correlation in evaluating platelet reactivity (r = -0.511). A significant although poor agreement (κ = 0.225) in identifying HPR and a significantly moderate agreement in identifying LPR (κ = 0.412) were observed between TEG and VerifyNow. By using TEG as the reference for comparison, the cutoff values of VerifyNow for the Chinese patients in this study were identified as PRU >205 for HPR and PRU <169 for LPR.</p><p><b>CONCLUSIONS</b>By comparing VerifyNow to TEG which has been widely used in clinics, VerifyNow could be an attractive alternative to TEG for monitoring on-clopidogrel platelet reactivity in Chinese patients.</p>
