OBJECTIVES: To investigate the hot topics in acupuncture-moxibustion research for treatment of aphasia and explore the current situation and trend of technology transformation in this field through analyzing the relevant Chinese literatures in recent 30 years by means of knowledge graph technology. METHODS: CiteSpace 6.1.R 2 and VOSviewer V1.6.16 software were used to collate the data, draw knowledge graphs and conduct visual analysis of the literatures related to acupuncture-moxibustion treatment of aphasia, searched from CNKI, WanFang and VIP databases.The time line view and strongest bursts of keywords were formed in the field of acupuncture-moxibustion treatment for aphasia. The treatment-based keyword networks were visualized. RESULTS: A total of 773 Chinese articles were included. Through visual analysis of the co-occurrence networks, the top 10 high-frequency overall keywords and the top 10 clusters of overall keywords were listed. The top 5 high-frequency aphasia categories were Broca aphasia, hysterical aphasia, transcortical motor aphasia, nominal aphasia and sensory aphasia. Regarding the keywords of the techniques of acupuncture-moxibustion, the occurrence frequencies of scalp acupuncture, tongue acupuncture, body acupuncture and electroacupuncture were ≥ 10 times.The occurrence frequencies of 16 acupoints were ≥25 times. After collation and cluster analysis of acupoints and techniques of acupuncture-moxibustion, 7 keyword clusters of "acupuncture techniques-acupoints" were obtained. The time line view showed that the strongest burst of keywords were transcranial magnatic stimulation, language rehabilitation training, acupuncture-medicine therapy and stroke, etc. in the recent 5 years. CONCLUSIONS: Acupuncture-moxibustion displays its unique advantage in treatment of aphasia. With the deepening of modern research, the hot topics for aphasia treated with acupuncture-moxibustion are present and the achievements enriched. In future, these therapeutic methods should be further investigated to explore a model of translational medicine for aphasia in line with the characteristics of acupuncture-moxibustion.

High flux MWCNTs-interlinked GO hybrid membranes survived in cross-flow filtration for the treatment of strontium-containing wastewater.

Graphene oxide (GO)-based membranes provide an encouraging opportunity to support high separation efficiency for wastewater treatment. However, due to the relatively weak interaction between GO nanosheets, it is difficult for bare GO-based membranes to survive in cross-flow filtration. In addition, the permeation flux of the bare GO membrane is not high sufficiently due to its narrow interlayer spacing. In this study, GO membranes interlinked with multi-walled carbon nanotubes (MWCNTs) via covalent bonds were fabricated on modified polyacrylonitrile (PAN) supports by vacuum filtration. Due to the strong bonds between GO, MWCNTs and the PAN membrane, the membranes could be used for the treatment of simulated nuclear wastewater containing strontium via a cross-flow process. The result showed a high flux of 210.7L/(m2h) at 0.4MPa, which was approximately 4 times higher than that of commercial nanofiltration membranes. The improved water permeation was attributed to the nanochannels created by the interlinked MWCNTs in the GO layers. In addition, the hybrid membrane exhibited a high rejection of 93.4% for EDTA-chelated Sr2+ in an alkaline solution, and could also be used to separate Na+/Sr2+ mixtures. These results indicate that the MWCNTs-interlinked GO membrane has promising prospects for application in radioactive waste treatment.
