OBJECTIVE:To evaluate the efficacy and safety of activating blood circulation and removing blood stasis in terms of Traditional Chinese Medicine(TCM) for managing renal fibrosis(RF) in patients with chronic kidney disease(CKD).METHODS:We searched randomized controlled trials(RCTs) from eight databases.RESULTS:Sixteen eligible studies with 1,356 participants were included in this study.Compared to treatment with Western Medicine(WM) alone,the combined treatment with activating blood circulation and removing blood stasis in terms of TCM(ARTCM) and WM to manage RF in patients with CKD significantly ameliorated type Ⅳ collagen(C-Ⅳ)(SMD:-2.17,95% CI:3.01 to-1.34),type Ⅲ procollagen(PC-Ⅲ)(SMD:-1.08,95% CI:-1.64 to-0.53),laminin(LN)(SMD:-1.28,95% CI:-1.65 to-0.90),transforming growth factor β 1(TGF-β1)(SMD:-0.65,95% CI:-1.18 to-0.12),serum creatinine(Scr)(SMD:-1.36,95% CI:-1.85 to-0.87),blood urea nitrogen(BUN)(MD:-1.51,95% CI:-2.59 to-0.43),and 24 h urine protein(24h Upro)(SMD:-1.23;95% CI:-1.96 to-0.50).The level of hyaluronic acid(HA) was similar in both types of treatment(SMD:-0.74,95% CI:-1.91 to 0.44).The subgroup analysis showed that the duration of 8 weeks might affect the concentration of C-Ⅳ,PC-Ⅲ,and LN(P < 0.05).The effectiveness of the longer duration to C-Ⅳ,PC-Ⅲ,and LN was not certain.However,the result should be interpreted in care.The safety of the treatment using ARTCM and WM could not be evaluated because a few studies had reported adverse effects.The results of the Meta-analysis were not stable enough.There was publication bias for the reports on Scr(P = 0.001),C-Ⅳ(P = 0.001),PC-Ⅲ(P = 0.026),and LN(P = 0.030) and no publication bias for the reports on BUN(P = 0.293).The quality of evidence varied from low to very low.CONCLUSIONS:The combined treatment using ARTCM and WM to manage RF in patients with CKD has some advantages over treatment with WM alone.High-quality RCTs need to be conducted for the strong support.

作者： Tao gan Dingsheng Wang Department of Chemistry Tsinghua UniversityBeijing 100084China

Catalysts can accelerate the chemical reaction rate and effectively promote the molecules transformation,which is of great significance in the research of chemical industry and material science.The extreme utilization of reactive sites has led to the emergence and development of atomically dispersed materials(ADMs).The highly active coordination unsaturated metal sites and fully utilized metal atoms make ADMs show great potential in catalytic reactions.The adjustment of coordination environment and electronic structure provides more possibilities for constructing reactive centers with different properties.This review summarized the application and research progress of ADMs in different fields.The design strategy and structure–activity relationship of ADMs for specific reactions were summarized and analyzed.Moreover,we also provided advices for the challenges and opportunities faced by ADMs in catalytic reactions.

Aqueous rechargeable Zn-metal batteries(ARZBs)are considered one of the most promising candidates for grid-scale energy storage.However,their widespread commercial application is largely plagued by three major challenges:The uncontrollable Zn dendrites,notorious parasitic side reactions,and sluggish Zn^(2+) ion transfer.To address these issues,we design a sustainable dual crosslinked cellulose hydrogel electrolyte,which has excellent mechanical strength to inhibit dendrite formation,high Zn^(2+) ions binding capacity to suppress side reaction,and abundant porous structure to facilitate Zn^(2+) ions migration.Consequently,the Zn||Zn cell with the hydrogel electrolyte can cycle stably for more than 400 h under a high current density of 10 mA cm^(−2).Moreover,the hydrogel electrolyte also enables the Zn||polyaniline cell to achieve high-rate and long-term cycling performance(>2000 cycles at 2000 mA g^(−1)).Remarkably,the hydrogel electrolyte is easily accessible and biodegradable,making the ARZBs attractive in terms of scalability and sustainability.

In this paper,the authors consider the distributed adaptive identification problem over sensor networks using sampled data,where the dynamics of each sensor is described by a stochastic differential equation.By minimizing a local objective function at sampling time instants,the authors propose an online distributed least squares algorithm based on sampled data.A cooperative non-persistent excitation condition is introduced,under which the convergence results of the proposed algorithm are established by properly choosing the sampling time interval.The upper bound on the accumulative regret of the adaptive predictor can also be provided.Finally,the authors demonstrate the cooperative effect of multiple sensors in the estimation of unknown parameters by computer simulations.

In this study,the cobalt-nickel layered double hydroxides(CoNi LDH)were synthesized with a variety of Co/Ni mass ratio,as CoxNiyLDHs.In comparison,Co1Ni3LDH presented the best peroxymonosulfate(PMS)activation efficiency for 2,4-dichlorophenol removal.Meanwhile,CoNi LDH@Nickel foam(CoNi LDH@NF)composite membrane was constructed for enhancing the stability of catalytic performance.Herein,CoNi LDH@NF-PMS system exerted high degradation efficiency of 99.22%within 90 min for 2,4-DCP when[PMS]_(0)=0.4 g/L,Co^(1)Ni^(3)LDH@NF=2 cm×2 cm(0.2 g/L),reaction temperature=298 K.For the surface morphology and structure of the catalyst,it was demonstrated that the CoNi LDH@NF composite membrane possessed abundant cavity structure,good specific surface area and sufficient active sites.Importantly,·OH,SO_(4)·^(-)and^(1)O_(2)played the primary role in the CoNi LDH@NF-PMS system for 2,4-DCP decomposition,which revealed the PMS activation mechanism in CoNi LDH@NF-PMS system.Hence,this study eliminated the stability and adaptability of CoNi LDH@NF composite membrane,proposing a new theoretical basis of PMS heterogeneous catalysts selection.

Ce-encapsulated Beta zeolite was synthesized by a one-pot hydrothermal method with citric acid complexing Ce in the absence of Na species.Additional citric acid can effectively prevent the deposition of Ce species during the hydrothermal synthesis of zeolites,leading to uniform distribution of Ce cluster in the framework of Beta zeolites.Moreover,the sodium-free synthesis system resulted that the Brønsted acid sites were mainly located on the straight channels and external surface of Beta zeolites,improving the utilization of Brønsted acid sites.In addition,Ce encapsulated Beta zeolites showed enhanced activity and robust stability in the alkylation of benzene with 1-dodecene based on the synergistic effect between Ce species and Brønsted acid sites,which pave the way for its practical application in the production of alkylbenzene.

Integrated high-performance and accurate shaping technology of low-cost powder metallurgy titanium alloys: A comprehensive review

引用

International Journal of Minerals,Metallurgy and Materials 2024年第3期31卷 413-426页

The practical engineering applications of powder metallurgy (PM) Ti alloys produced through cold compaction and pressure-less sintering are impeded by poor sintering densification, embrittlement caused by excessive O impurities, and severe sintering deforma-tion resulting from the use of heterogeneous powder mixtures. This review presents a summary of our previous work on addressing the above challenges. Initially, we proposed a novel strategy using reaction-induced liquid phases to enhance sintering densification. Near- complete density (relative density exceeding 99%) was achieved by applying the above strategy and newly developed sintering aids. By focusing on the O-induced embrittlement issue, we determined the onset dissolution temperature of oxide films in the Ti matrix. On the basis of this finding, we established a design criterion for effective O scavengers that require reaction with oxide films before their dissol-ution. Consequently, a ductile PM Ti alloy was successfully obtained by introducing 0.3wt% NdB6 as the O scavenger. Lastly, a powder- coating strategy was adopted to address the sintering deformation issue. The ultrafine size and shell-like distribution characteristics of coating particles ensured rapid dissolution and homogeneity in the Ti matrix, thereby facilitating linear shrinkage during sintering. As a result, geometrically complex Ti alloy parts with high dimensional accuracy were fabricated by using the coated powder. Our fundament-al findings and related technical achievements enabled the development of an integrated production technology for the high-performance and accurate shaping of low-cost PM Ti alloys. Additionally, the primary engineering applications and progress in the industrialization practice of our developed technology are introduced in this review.

Passive jamming is believed to have very good potential in countermeasure community.In this paper,a passive angular blinking jamming method based on electronically controlled corner reflectors is proposed.The amplitude of the incident wave can be modulated by switching the corner reflector between the penetration state and the reflection state,and the ensemble of multiple corner reflectors with towing rope can result in complex angle decoying effects.Dependency of the decoying effect on corner reflectors’radar cross section and positions are analyzed and simulated.Results show that the angle measured by a monopulse radar can be significantly interfered by this method while the automatic tracking is employed.

As a sustainable mode of travel,carpooling is an effective solution to environmental and energy problems,but it has not been fully utilized.The research on carpooling attitudes,especially for college students,still needs to be improved.In response to this problem,this paper aims to investigate the effect of personal attributes,travel attributes,attitude attributes and other attributes of students on carpooling attitudes in China.To collect the data,an online questionnaire survey was implemented at Shenzhen University,and 514 students participated.Based on the samples,the multinomial logit model is used to explore the contribution of all variables.The model results showed that personal attributes such as sex and age had no significant effect on the attitude of college students towards carpooling.The safety of carpooling and its high cost make college students have a neutral attitude towards it.The most concerning factor for college students in carpooling is comfort.These findings can provide valuable suggestions for measures to be taken in response to different attributes affecting students’attitudes and are particularly important for the university and government to make optimal decisions to motivate students to select carpooling.
