The TCR between the solid–liquid contact surface is much smaller than that of the solid–solid contact surface, but conventional solid–liquid phase change materials are likely to cause serious leakage. Therefore, this work has prepared a new formstable phase change thermal interface material. Through the melt blending of paraffin wax(PW) and low-density polyethylene(LDPE), the stability is improved and it has an excellent coating effect on PW. The addition of aluminum(Al) powder improves the low thermal conductivity of PW/LDPE, and the addition of 15wt% Al powder improves the thermal conductivity of the internal structure of the matrix by 67%. In addition, the influence of the addition of Al powder on the internal structure, thermal properties, and phase change behavior of the PW/LDPE matrix was systematically studied. The results confirmed that the addition of Al powder improved the thermal conductivity of the material without a significant impact on other properties, and the thermal conductivity increased with the increase of Al addition. Therefore, morphologically stable PW/LDPE/Al is an important development direction for TIMs.展开更多

However, the brittleness, low toughness,and poor mechanical and electrical stabilities of TMD-based films limit their application. Herein, a TaS_(2) freestanding film with ultralow void ratio of 6.01% is restacked under the effect of bond-free van der Waals(vdW) interactions within the staggered 2H-TaS_(2) nanosheets.The restacked films demonstrated an exceptionally high electrical conductivity of 2,666 S cm^(-1), electromagnetic interference shielding effectiveness(EMI SE) of 41.8 dB, and absolute EMI SE(SSE/t) of 27,859 dB cm^(2) g^(-1), which is the highest value reported for TMD-based materials. The bond-free vdW interactions between the adjacent 2H-TaS_(2) nanosheets provide a natural interfacial strain relaxation, achieving excellent flexibility without rupture after 1,000 bends. In addition, the TaS_(2) nanosheets are further combined with the polymer fibers of bacterial cellulose and aramid nanofibers via electrostatic interactions to significantly enhance the tensile strength and flexibility of the films while maintaining their high electrical conductivity and EMI SE.This work provides promising alternatives for conventional materials used in EMI shielding and nanodevices.展开更多

Some plant natural products, especially several flavonoids, are effective inhibitors of Srt A. However, given the limited number of inhibitors and the development of drug resistance, the discovery of new inhibitors is urgent. Here, the high-throughput virtual screening approach was performed to identify new potential inhibitors of S. mutans Srt A. Two libraries were used for screening, and nine compounds that had the lowest scores were chosen for further molecular dynamics simulation, binding free energy analysis and absorption, distribution, metabolism, excretion and toxicity(ADMET)properties analysis. The results revealed that several similar compounds composed of benzofuran, thiadiazole and pyrrole, which exhibited good affinities and appropriate pharmacokinetic parameters, were potential inhibitors to impede the catalysis of Srt A.In addition, the carbonyl of these compounds can have a key role in the inhibition mechanism. These findings can provide a new strategy for microbial infection disease therapy.展开更多

Thus, it is highly desirable to develop high-performance electrode materials with high thermal conductivity. Here, we report a facile one-step electrodeposition method to synthesize ternary cobalt nickel sulfide(CoNi_2S_4)flower-like nanosheets which are grown on graphite foil(GF) as binder-free electrode materials for supercapacitors. The as-fabricated GF/CoNi_2S_4 integrated electrode manifested an excellent thermal conductivity of 620.1 W·m^(-1)·K^(-1) and a high specific capacitance of 881 F·g^(-2) at 5 mA cm^(-2), as well as good rate capability and cycling stability. Ultimately, the all-solid-state symmetric supercapacitor based on these advanced electrodes demonstrated superior heat dissipation performance during the galvanostatic charge-discharge processes. This novel strategy provides a new example of effective thermal management for potential applications in energy storage devices.展开更多

[Methods] A syndrome score scale that was suitable for evaluating the rat models was established according to the evolvement rules of etiology and pathogenesis of TCM and the modern clinical pathological mechanism. At the same time,bifendate pills and Sanqi Zhigan pills were selected as drug counterevidence for the models. Rats in model groups were given different proportions of high-fat and low-protein fodder and different concentrations of alcohol every day,and intraperitoneally injected with porcine serum twice a week. Drug groups were given with bifendate pills and Sanqi Zhigan pills( 8. 1 mg/kg,and 2. 7 g/kg) respectively for 14 consecutive days.During the experiment,general status,weight,daily fodder intake and daily water intake of the animals were observed,and TCM syndromes were scored. After the experiment,the levels of alanine aminotransferase( ALT),aspartate aminotransferase( AST),γ-glutamine transpeptidase( γ-GT),total cholesterol( TC),triglycerides( TG),low density lipoprotein-cholesterol( LDL-C),and high density lipoprotein-cholesterol( HDL-C) in serum were detected,and the pathological changes in liver tissue were observed. [Results] Compared with the control group,body weight,daily fodder and water intake of rats increased slowly in the model group,and the levels of ALT,AST,γ-GT,TC,TG and LDL-C increased significantly,while the level of HDL-C dropped. Pathological examination showed that steatosis and fat granule were observed in hepatocytes of rats in the model group. Behavioral observation found that main symptoms and minor symptoms of rats in the model group conformed to the syndrome manifestation of liver depression and spleen deficiency,which suggested that the three model groups were established successfully. Among them,three rats died in model group 1,and one rat died in model group 2. The manifestation of all the above lesions can be alleviated by drug counterevidence. [Conclusions]The animal model of fatty liver due to liver depression and spleen deficiency shows an obviously lower mortality and shorter duration and can be used for research of correlation between prescription and syndrome and its mechanism.展开更多

文摘Oxygen carriers(OCs)with perovskite structure are attracting increasing interests due to their redox tunability by introducing various dopants in the structure.In this study,LaNixFe1-xO3(x=0,0.1,0.3,0.5,0.7,1.0)perovskite OCs have been prepared by a citric acid–nitrate sol–gel method,characterized by means of X-ray diffraction(XRD)analysis and tested for algae chemical looping gasification in a fixed bed reactor.The effects of perovskite types,OC/biomass mass ratio(O/B),gasification temperature and water injection rate on the gasification performance were investigated.Lower Ni-doped(0≤x≤0.5)perovskites crystalized in the rhombohedra system which was isostructural with LaNiO3,while those with composition 0.5≤x≤1 crystalized in the orthorhombic system.Despite the high reactivity for LaNiO_(3),LaNi_(0.5)Fe_(0.5)O_(3)(LN5F5)was found to be more stable at a high temperature and give almost as good results as LaNiO_(3)in the formation of syngas.The relatively higher syngas yield of 0.833 m^(3)·kg^(-1) biomass was obtained under the O/B of 0.4,water injection rate of 0.3 ml·min^(-1) and gasification temperature at 850C.Continuous high yield of syngas was achieved during the first 5 redox cycles,while a slight decrease in the reactivity for LN5F5 after 5 cycles was observed due to the adhesion of small grains occurring on the surface of OCs.However,an obvious improvement in the gasification performance was attained for LN5F5 compared to raw biomass direct gasification,indicating that LN5F5 is a promising functional OC for chemical looping catalytic gasification of biomass.

文摘Effective heat dissipation is a crucial issue in electrochemical energy storage devices. Thus, it is highly desirable to develop high-performance electrode materials with high thermal conductivity. Here, we report a facile one-step electrodeposition method to synthesize ternary cobalt nickel sulfide(CoNi_2S_4)flower-like nanosheets which are grown on graphite foil(GF) as binder-free electrode materials for supercapacitors. The as-fabricated GF/CoNi_2S_4 integrated electrode manifested an excellent thermal conductivity of 620.1 W·m^(-1)·K^(-1) and a high specific capacitance of 881 F·g^(-2) at 5 mA cm^(-2), as well as good rate capability and cycling stability. Ultimately, the all-solid-state symmetric supercapacitor based on these advanced electrodes demonstrated superior heat dissipation performance during the galvanostatic charge-discharge processes. This novel strategy provides a new example of effective thermal management for potential applications in energy storage devices.

文摘Backgroud:To evaluate the clinical efficacy and safety of Dachaihu Decoction in the treatment of acute pancreatitis(AP)with the traditional Chinese medicine(TCM)syndrome of liver qi depression and liver-gallbladder dampness-heat.Methods:We searched randomized controlled trials of Dachaihu Decoction in the treatment of AP with the TCM syndrome of liver qi depression and liver-gallbladder dampness-heat from databases in CNKI,WanFang,VIP,Embase,PubMed,and Cochrane Library(from established to August 2019).All the retrieved documents were imported into the Noteexpress software for screening and management,and the included documents were evaluated for quality and data extracted.Statistical analysis was performed with RevMan(version 5.3).Results:A total of 132 articles were retrieved and 8 studies were included to analysis,including 679 patients.Quality evaluation of included studies suggested that the quality of the literatures is generally not high.Meta-analysis showed that the total clinical effective rate of AP was higher in the treatment group than in the control group[OR=5.00,95%CI(2.86,8.73)],and the difference was statistically significant(P<0.00001).The patient's abdominal pain relief time[MD=-0.57,95%CI(-0.86,-0.27),P=0.0002],bloating relief time[MD=-0.71,95%CI(-1.05,-0.37),P=0.04],time of serum amylase returning to normal[MD=-1.00,95%CI(-1.60,-0.40),P=0.001]and time of urinary amylase returning to normal[MD=-1.62,95%CI(-2.88,-0.37),P=0.01]all lower than the control group.But there was no statistically significant difference between the treatment group and the control group at the first defecation time[MD=-0.86,95%CI(-1.75,-0.03),P=0.06].The patient's serum TNF-a levels on the 3rd[MD=-28.53,95%CI(-49.57,-7.49),P=0.008]and 7th day[MD=-26.13,95%CI(-49.76,-2.50),P=0.03]in the treatment group were statistically lower in the treatment group than in the control group.Similarly,the patient's serum IL-6 levels on the 3rd[MD=-6.62,95%CI(-12.49,-0.75),P=0.03]and 7th day[MD=-11.98,95%CI(-22.25,-1.71),P=0.02]were also statistically lower in the treatment group than in the control group.No serious complications or adverse reactions were observed.Conclusion:Dachaihu Decoction combined with western medicine in the treatment of AP with the TCM syndrome of liver qi depression and liver-gallbladder dampness-heat can improve clinical efficacy compared with western medicine alone.In addition,the combination therapy method is safe and can be used for syndrome differentiation of AP patients in the clinic.

文摘In recent years,zinc oxide nanoparticles(ZnO NPs)have been widely used as zinc fertilizers and pesticides.The use of ZnO NPs in this way can provide benefits to humans,but also has potential risks.ZnO NPs inevitably enter the environment during their production and use,which affects the ecological environment and crop growth.In order to investigate the phenotype,physiology,and gene expression of barley(Hordeum vulgare L.)seedlings under ZnO NPs stress,the barely cultivars ZJU3(P21),Golden Promise(GP)and L23 were chosen for study.Different ZnO NPs concentrations were applied to compare the physiological and biochemical indexes of the barley seedlings and the responses of six stress-related genes,when seedlings were cultured to the two-leaf stage through hydroponics.The results showed that the density of brown spots on the leaf surface increased with increasing ZnO NPs concentration.ZnO NPs stress inhibited the root growth of barley seedlings,and P21 was the most sensitive.Furthermore,ZnO NPs stress could stimulate plants to produce a large number of reactive oxygen species(ROS),resulting in an imbalance between the production and removal of ROS and membrane lipid peroxidation in plants.This imbalance inhibited the growth and development of the barley seedlings.With increasing ZnO NPs concentration,the activity of superoxide dismutase was gradually increased,the activity of catalase was progressively decreased,and the contents of malondialdehyde and proline were increased.Compared with the control,among six stress-related genes,the expression levels of five genes were downregulated and one gene was upregulated in the experimental group.This study preliminarily revealed the toxic effect of ZnO NPs on seedlings and the effect on the expression of stress-related resistance genes in different barley varieties.

文摘Objective:Present study aimed to explore the effects of intermittent cold-exposure(ICE)on culprit plaque morphology in patients with ST-segment elevation myocardial infarction(STEMI)in frigid zone.Methods:Totally 848 STEMI patients with plaque rupture(N=637)or plaque erosion(N=211)were enrolled consecutively according to optical coherence tomography imaging.Data on the changes of outdoor air temperature corresponding to 24 solar terms were collected.Patients were divided into different groups according to 24 solar terms and the number of days with indoor central heating.Imaging data were measured and analyzed qualitatively and quantitatively.Statistical analysis was conducted to elucidate the possible association of the STEMI patients of different groups with plaque morphology of culprit vessel with alterations of ambient temperature.Results:The incidence of both plaque rupture and plaque erosion presented trough in summer.The incidence of plaque rupture reached a peak value in early winter when outdoor air temperature dropped below 0℃and declined with supply of central heating.Persistent cold exposure in early winter was positively and significantly associated with plaque rupture.The incidence of plaque erosion presented a peak in severe winter with outdoor air temperature dropping below-20℃and steady supply of central heating.ICE in severe winter was positively and significantly associated with plaque with intact intima,especially in aged male or current smoking patients.The positive correlation of cold exposure with lipid size in culprit plaque in winter weakened with central heating.Conclusion:ICE resulted from switching staying in between outdoor cold environment and indoor warm temperature with central heating in severe winter changed culprit plaque morphology in STEMI.Plaque rupture decreased whereas plaque erosion increased impacted by ICE.The effect of ICE on the transformation of plaque morphology might be explained by reduced lipid deposition.

文摘[Objectives] To establish animal models of fatty liver due to liver depression and spleen deficiency that were suitable for activity discovery of traditional Chinese medicine( TCM) compounds,efficacy evaluation,new drug research and development and correspondence between prescription and syndrome of TCM. [Methods] A syndrome score scale that was suitable for evaluating the rat models was established according to the evolvement rules of etiology and pathogenesis of TCM and the modern clinical pathological mechanism. At the same time,bifendate pills and Sanqi Zhigan pills were selected as drug counterevidence for the models. Rats in model groups were given different proportions of high-fat and low-protein fodder and different concentrations of alcohol every day,and intraperitoneally injected with porcine serum twice a week. Drug groups were given with bifendate pills and Sanqi Zhigan pills( 8. 1 mg/kg,and 2. 7 g/kg) respectively for 14 consecutive days.During the experiment,general status,weight,daily fodder intake and daily water intake of the animals were observed,and TCM syndromes were scored. After the experiment,the levels of alanine aminotransferase( ALT),aspartate aminotransferase( AST),γ-glutamine transpeptidase( γ-GT),total cholesterol( TC),triglycerides( TG),low density lipoprotein-cholesterol( LDL-C),and high density lipoprotein-cholesterol( HDL-C) in serum were detected,and the pathological changes in liver tissue were observed. [Results] Compared with the control group,body weight,daily fodder and water intake of rats increased slowly in the model group,and the levels of ALT,AST,γ-GT,TC,TG and LDL-C increased significantly,while the level of HDL-C dropped. Pathological examination showed that steatosis and fat granule were observed in hepatocytes of rats in the model group. Behavioral observation found that main symptoms and minor symptoms of rats in the model group conformed to the syndrome manifestation of liver depression and spleen deficiency,which suggested that the three model groups were established successfully. Among them,three rats died in model group 1,and one rat died in model group 2. The manifestation of all the above lesions can be alleviated by drug counterevidence. [Conclusions]The animal model of fatty liver due to liver depression and spleen deficiency shows an obviously lower mortality and shorter duration and can be used for research of correlation between prescription and syndrome and its mechanism.

文摘To achieve advanced nitrogen removal from actual municipal sewage,a novel multistage anoxic/aerobic process with sludge regeneration zone(R-MAO)was developed.The reactor was used to treat actual domestic sewage and the nitrogen removal capacity of the sludge regeneration zone(R zone)was investigated during the long-term operation.The best performance was obtained at the R zone’s Oxidation-Reduction Potential(ORP)of-50±30 mV and hydraulic residence times(HRT)of 1.2 hr.The average effluent COD,TN,NH_(4)^(+)-N and NO_(3)^(−)-N of the R-MAO process were 18.0±2.3,7.5±0.6,1.0±0.5 and 4.6±0.4 mg/L,respectively,with the corresponding removal efficiency of COD,TN and NH_(4)^(+)-N were 92.9%±1.0%,84.1%±1.5% and 97.5%±1.1%.Compared to the sole MAO system,the TN removal efficiency of the R-MAO increased by 10.1%.Besides,under the optimal conditions,the contribution of the R zone in the R-MAO that removal COD,TN,NH_(4)^(+)-N and NO_(3)^(−)-N were 0.36,0.15,0.032 and 0.82 g/day.High-throughput sequencing results showed that uncultured_bacterium_f_Burkholderiaceae(5.20%),OLB8(1.04%)and Ottowia(1.03%)played an important role in denitrification in the R zone.This study provided effective guidance for the design and operation of the R-MAO process in domestic sewage treatment.

文摘Despite immune checkpoint blockade(ICB)therapy has transformed cancer treatment,only 20.2%of these patients achieved a response.Understanding resistance mechanisms to ICB is important for the treatment of a wider population.In this work,we occasionally found that the silica nanoparticles(SiO_(2)NPs)accumulated in the liver can induce resistance to following ICB therapy to a subcutaneous tumor in mice.By analysis of T cells frequency,we uncovered that SiO_(2)NPs in the liver resulted in a siphoning of T cells from circulation to the liver by produced chemokines.In addition,liver immunosuppressive cells further inhibit the function and induce apoptosis of recruited T cells,leading to a systemic loss and reduced tumor infiltration of T cells,which contributes to poor responses to ICB therapy.However,such effect is not observed in poly(lactic-co-glycolic acid)(PLGA)NPs treated mice under the same conditions,likely due to their much lower immunogenicity in perturbing the liver immune microenvironment,indicating that cancer is not a local disease but an ecosystem that is linked to the distal environment.We further provide a new mechanism insight into ICB resistance induced by liver accumulation of nanoparticles.

文摘Conductive adhesive tape is one kind of electromagnetic interference(EMI)shielding materials for electronic packaging.However,the inferior conductivity of the pressure-sensitive adhesive(PSA)layer results in serious electromagnetic leakage at the conjunctions between the conductive tapes and target objects.Adding conductive fillers is a traditional method for highly conductive adhesive tapes.However,the content of conductive fillers is needed to reach the percolation threshold,which is usually as high as tens of percent.High-content fillers result in significant loss of adhesive property and high fabrication cost.Herein,we introduce a rational architecture of conductive microsphere monolayer(CMM)in the PSA layer.The CMM connects the top and bottom surfaces of the PSA layer and improves its conductivity in the z-direction.Importantly,low contents of conductive microspheres(≤5%(mass fraction,w))can achieve the target of conductivity improvement,but not result in the serious loss of the adhesive property.Therefore,the strategy of CMMs can balance the tradeoff between the conductivity and the adhesive property of conductive PSA tapes.Finally,we demonstrate the superior EMI shielding performance of as-made conductive adhesive tapes,indicating their potential applications as the advanced EMI shielding materials in the electronic packaging.

文摘Nonalcoholic fatty liver disease(NAFLD)has become one of the most prominent causes of chronic liver diseases and malignancies.However,few therapy has been approved.Radix Bupleuri(RB)is the most frequently used herbal medicine for the treatment of liver diseases.In the current study,we aim to systemically evaluate the therapeutic effects of saikosaponin A(SSa)and saikosaponin D(SSd),the major bioactive monomers in RB,against NAFLD and to investigate the underlying mechanisms.Our results demonstrated that both SSa and SSd improved diet-induced NAFLD.Integrative lipidomic and transcriptomic analysis revealed that SSa and SSd modulated glycerolipid metabolism by regulating related genes,like Lipe and Lipg.SSd profoundly suppressed the fatty acid biosynthesis by downregulating Fasn and Acaca expression and promoted fatty acid degradation by inducing Acox1 and Cpt1 a expression.Bioinformatic analysis further predicted the implication of master transcription factors,including peroxisome proliferator-activated receptor alpha(PPARα),in the protective effects of SSa and SSd.These results were further confirmed in vitro in mouse primary hepatocytes.In summary,our study uncoded the complicated mechanisms underlying the promising anti-steatosis activities of saikosaponins(SSs),and provided critical evidence inspiring the discovery of innovative therapies based on SSa and SSd for the treatment of NAFLD and related complications.
