OBJECTIVE:To evaluate the efficacy and safety of acupuncture and moxibustion therapy(AMT) for cancerrelated psychological symptoms(CRPS) of insomnia,depression and anxiety.METHODS:Seven databases were searched for randomized controlled trials(RCT) comparing AMT to routine care or conventional drug for alleviating CRPS of insomnia,depression,and anxiety before April 2020.Two independent reviewers performed the data extraction and assessed the risk of bias.RESULTS:A total of 30 RCTs involving 2483 cancer patients were enrolled.The pooled analysis indicated that the treatment group was significantly better than the control group in improving the depression effective rate [RR = 1.29,95% CI(1.12,1.49),P = 0.0004],the quality of life(QOL) [MD = 1.11,95% CI(0.80,1.42),P < 0.000 01],and reducing Self-rating Anxiety Scale(SAS) [MD =﹣7.75,95% CI(﹣10.44,﹣5.05),P < 0.000 01].But there was no statistically significant difference between two groups in improving the insomnia effective rate [RR = 1.18,95% CI(0.93,1.51),P = 0.18].The subgroup analysis showed the effectiveness of different intervention on CRPS.Compared with routine care,AMT helps relieve CRPS better evaluated by Pittsburgh Sleep Quality Index(PSQI),Hamilton Depression Scale(HAMD),and Self-rating Depression Scale(SDS),and depression effective rate.Compared with conventional drug,AMT performs better evaluated by SDS,depression effective rate and QOL.Moreover,the conventional drug showed higher treatment efficacy on improving insomnia effective rate compared with AMT.Compared to conventional drug,AMT plus conventional drug resulted in a significant reduction on CRPS such as PSQI,HAMD,SDS,and SAS,and also had a meaningful improvement on insomnia effective rate,depression effective rate and QOL.Fewer published reports were found on the adverse events of AMT than the conventional drug.CONCLUSION:The results suggested that AMT might be effective in improving CPRI;however,a definite conclusion could not be drawn because the quality of trials are low.Further large-scale an

The development of carbon materials with high electrochemical performance for next-generation energy device is emerging, especially N, S co-doped carbon materials have sparked intensive attention. However,the exploration of N, S co-doped carbon with well-defined active sites and hierarchical porous structures are still limited. In this study, we prepared a series of edge-enriched N, S co-doped carbon materials through pyrolysis of thiourea(TU) encapsulated in zeolitic imidazolate frameworks(TU@ZIF) composites,which delivered very good oxygen reduction reaction(ORR) performance in alkaline medium with onset potential of 0.94 V vs. reversible hydrogen electrode(RHE), good stability and methanol tolerance. Density functional theory(DFT) calculations suggested that carbon atoms adjacent to N and S are probable active sites for ORR intermediates in edge-enriched N, S co-doped carbon materials because higher electron density can enhance O_(2)adsorption, lower formation barriers of intermediates, improving the ORR performance comparing to intact N, S co-doped carbon materials. This study might provide a new pathway for improving ORR activity by the integration engineering of edge sites, and electronic structure of heteroatom doped carbon electrocatalysts.

Constructing anodes with fast ions/electrons transfer paths is an effective strategy to achieve high-performance sodium ion batteries(SIBs)/potassium ion batteries(PIBs). Amorphous carbon is a promising candidate anode for SIBs/PIBs owing to its disordered carbon layers, abundant defects/pores, and lowcost resources. However, the larger radius of Na^(+)/K^(+) leading to depressed kinetics and poor cycling performance, impeding their further applications. Herein, we propose an efficient strategy to construct of nitrogen, sulfur co-doped hollow carbon nanospheres(NS-HCS) involving an in situ growth of polydopamine on nano-Ni(OH)2template with subsequent sulfur doping process. During the formation process, the produced Ni nanospheres play as the hard template and catalyst for the formation of hollow carbon nanosphere with partially graphite microcrystalline structure, while the sulfur doping process can enlarge the interlayer space and create more defects on the surface of carbon nanospheres, thus synchronous improve the Na^(+)/K^(+) insertion and adsorption ability in NS-HCS. With the synergistic control of the enlarged interlayer spacing, high content of pyridinic N/pyrrolic N and graphitization, a hybrid storage mechanism facilitates the transport kinetics and endows the NS-HCS electrode with high capacities and good cycling stability in SIBs and PIB. Benefit from the multiple effects, NS-HCS exhibits the improved capacity of 274.8 m Ah/g at 0.1 A/g and excellent cycling stability of 149.5 m Ah/g after 5000 cycles at2.5A/g in SIBs, as well as good potassium ion storage behavior with a high capacity retention of 76.5%after 700 cycles at 1.0 A/g, demonstrating the potential applications of NS-HCS for high-performance SIBs and PIBs.

In recent years,explosion shock wave has been considered as a signature injury of the current military conflicts.Although strong shock wave is lethal to the human body,weak shock wave can cause many more lasting consequences.To investigate the protection ability and characteristics of flexible materials and structures under weak shock wave loading,the blast wave produced by TNT explosive is loaded on the polyurethane foam with the density of 200.0 kg/m3(F-200)and 400.0 kg/m3(F-400),polyurea with the density of 1100.0 kg/m^(3)(P-1100)and structures composed of the two materials,which are intended for individual protection.Experimental results indicate that the shock wave is attenuated to weak pressure disturbance after interacting with the flexible materials which are not damaged.The shock wave protective capability of single-layer materials is dependent on their thickness,density and microscopic characteristics.The overpressure,maximum pressure rise rate and impulse of transmitted wave decrease exponentially with increase in sample thickness.For the same thickness,F-400 provides better protective capability than F-200 while P-1100 shows the best protective capability among the three materials.In this study,as the materials are not destroyed,F-200 with a thickness more than10.0 mm,F-400 with a thickness more than 4.0 mm,and P-1100 with a thickness more than 1.0 mm can attenuate the overpressure amplitude more than 90.0%.Further,multi-layer flexible composites are designed.Different layer layouts of designed structures and layer thickness of the single-layer materials can affect the protective performance.Within the research range,the structure in which polyurea is placed on the impact side shows the optimal shock wave protective performance,and the thicknesses of polyurea and polyurethane foam are 1.0 mm and 4.0 mm respectively.The overpressure attenuation rate reached maximum value of 93.3%and impulse attenuation capacity of this structure are better than those of single-layer polyurea and polyurethane foam with

Launching the intermolecular through-space charge transfer(TSCT)from a bicomponent assembly for photophysical property manipulation is of great significance in fluorescence probe design.Here,we demonstrate the elaborate control of droplet evaporation dynamics for intermolecular TSCT can facilitate the ultrasensitive detection of JWH-018,a representative synthetic cannabinoid.Driven by diverse intermolecular interactions,the probe,and JWH-018 assemble in a closely stacked manner to emit strong fluorescence at 477 nm,ascribing to the intermolecular TSCT at the S2 state.The strategy realizes an ultra-low limit of detection of 11 nmol/mL and great selectivity towards JWH-018.The practicability is further verified by constructing a sensing chip for JWH-018 aerosol detection,which facilitates the on-site drug abuser screening with the naked eye.Moreover,the proposed assembly-enabled TSCT is expected to find a variety of applications for optoelectronic materials design and photophysical mechanism-dominated molecular recognition.

A series of N-doped carbon materials(NCs)were synthesized by using biomass citric acid and dicyandiamide as renewable raw materials via a facile onestep pyrolysis method. The characterization of microstructural features shows that the NCs samples are composed of few-layered graphene-like nanoflakes with controlled in situ N doping, which is attributed to the confined pyrolysis of citric acid within the interlayers of the dicyandiamide-derived g-C_3N_4 with high nitrogen contents. Evidently, the pore volumes of the NCs increased with the increasing content of dicyandiamide in the precursor. Among these samples, the NCs nanoflakes prepared with the citric acid/dicyandiamide mass ratio of 1:6, NC-6,show the highest N content of ~6.2 at%, in which pyridinic and graphitic N groups are predominant. Compared to the commercial Pt/C catalyst, the as-prepared NC-6 exhibits a small negative shift of ~66 mV at the half-wave potential, demonstrating excellent electrocatalytic activity in the oxygen reduction reaction. Moreover, NC-6 also shows better long-term stability and resistance to methanol crossover compared to Pt/C. The efficient and stable performance are attributed to the graphene-like microstructure and high content of pyridinic and graphitic doped nitrogen in the sample, which creates more active sites as well as facilitating charge transfer due to the close four-electron reaction pathway. The superior electrocatalytic activity coupled with the facile synthetic method presents a new pathway to cost-effective electrocatalysts for practical fuel cells or metal–air batteries.

Primary bile acids were reported to augment secretion of chemokine(C-X-C motif)ligand16(CXCL16)from liver sinusoidal endothelial cells(LSECs)and trigger natural killer T(NKT)cellbased immunotherapy for liver cancer.However,abundant expression of receptors for primary bile acids across the gastrointestinal tract overwhelms the possibility of using agonists against these receptors for liver cancer control.Taking advantage of the intrinsic property of LSECs in capturing circulating nanoparticles in the circulation,we proposed a strategy using nanoemulsion-loaded obeticholic acid(OCA),a clinically approved selective farnesoid X receptor(FXR)agonist,for precisely manipulating LSECs for triggering NKT cell-mediated liver cancer immunotherapy.The OCA-nanoemulsion(OCA-NE)was prepared via ultrasonic emulsification method,with a diameter of 184 nm and good stability.In vivo biodistribution studies confirmed that the injected OCA-NE mainly accumulated in the liver and especially in LSECs and Kupffer cells.As a result,OCA-NE treatment significantly suppressed hepatic tumor growth in a murine orthotopic H22 tumor model,which performed much better than oral medication of free OCA.Immunologic analysis revealed that the OCA-NE resulted in augmented secretion of CXCL16 and IFN-g,as well as increased NKT cell populations inside the tumor.Overall,our research provides a new evidence for the antitumor effect of receptors for primary bile acids,and should inspire using nanotechnology for precisely manipulating LSECs for liver cancer therapy.
