Objective: The objective of this study was to explore the safety, efficacy, economy, and other aspects of frequently-used antitumor Chinese patent medicine injections through a comprehensive evaluation of evidence-based medical research to provide scientific information and decision-making basis for drug selection, rational drug use, public awareness of safe drug use, and medical insurance. Materials and Methods: The names of five frequently used antitumor Chinese patent medicine injections were used as search terms, including the compound Sophora flavescens injection, Kangai injection, Aidi injection, Kanglaite injection, and Brucea javanica oil emulsion injection. Relevant evidence-based medical research was extracted from the databases. A descriptive evaluation was conducted, and the Markov model was used for the cost-benefit analysis. Finally, the above injections are ranked by comprehensive scores using the multi-criteria decision analysis and Delphi method. Results: The five injections had their own advantages in enhancing the effectiveness of anti-tumor treatments, improving the quality of life for cancer patients, and reducing the incidence of adverse reactions. From the perspective of economy and other attributes, compound S. flavescens was superior to B. javanica oil, Aidi, Kangai, and Kanglaite. After a comprehensive evaluation of the above five injections, the compound S. flavescens injection received the highest score. Conclusions: Compound S. flavescens, Kangai, Aidi, B. javanica oil, and Kanglaite have their own advantages in effectiveness and no significant difference in safety. Compound S. flavescens injection has the highest comprehensive score. Clinical attention should be paid to monitoring the initial stage of medication and special groups.

The perfluorosulfonic acid(PFSA) membrane doped with two-dimensional conductive filler Ti_(3)C_(2)T_(x) is a fuel cell proton exchange membrane with high application potential. Experimental studies showed that the proton conductivity of Nafion/Ti_(3)C_(2)T_(x) composite membrane is improved significantly compared with that in pure Nafion. However, the microscopic mechanism of doping on the enhancement of membrane performance is remain unclear now. In this work, molecular dynamics simulation was used to investigate the microscopic morphology and proton transport behaviors of Nafion/Ti_(3)C_(2)T_(x) composite membrane at the molecular level. The results shown that there were significant differences about the diffusion kinetics of water molecules and hydroxium ions in Nafion/Ti_(3)C_(2)T_(x) at low and high hydration levels in the nanoscale *** the increase of water content, Ti_(3)C_(2)T_(x) in membrane was gradually surrounded by ambient water molecules to form a hydration layer, and forming a relatively continuous proton transport channel between Nafion polymer and Ti_(3)C_(2)T_(x) monomer. The continuous proton transport channel could increase the number of binding sites of proton and thus achieving high proton conductivity and high mobility of water molecules at higher hydration level. The current work can provide a theoretical guidance for designing new type of Nafion composite membranes.

Cathode materials that possess high output voltage,as well as those that can be mass-produced using facile techniques,are crucial for the advancement of aqueous zinc-ion battery(ZIBs)applications,Herein,we present for the first time a new porous K_(0.5)VOPO_(4)·1.5H_(2)O polyanionic cathode(P-KIVP)with high output voltage(above 1.2 V)that can be manufactured at room temperature using straightforward coprecipitation and etching *** P-KVP cathode experiences anisotropic crystal plane expansion via a sequential solid-solution intercalation and phase co nversion pathway throughout the Zn^(2+)storage process,as confirmed by in-situ synchrotron X-ray diffraction and ex-situ X-ray photoelectron *** to other layered vanadium-based polyanionic materials,the P-KVP cathode experiences a progressive decline in voltage during the cycle,which is demonstrated to be caused by the irreversible conversion into amorphous VO_(x).By introducing a new electrolyte containing Zn(OTF)_(2) to a mixed triethyl phosphate and water solution,it is possible to impede this irreversible conversion and obtain a high output voltage and longer cycle life by forming a P-rich cathode electrolyte interface *** a proof-of-concept,the flexible fiber-shaped ZIBs based on modified electrolyte woven into a fabric watch band can power an electronic watch,highlighting the application potential of P-KVP cathode.
