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.
目的: 通过知识图谱技术分析近30年针灸治疗失语症的中文文献，探讨此领域的研究热点及技术转化的现状与趋势。方法: 采用CiteSpace 6.1.R 2及VOSviewer V1.6.16软件对中国知网、万方数据知识服务平台和维普期刊全文数据库中针灸治疗失语症相关文献进行数据整理、绘制知识图谱，形成针灸治疗失语症研究领域的关键词时间轴视图谱和治疗关键词关系网络关联图谱，进行可视化分析。结果: 共纳入中文文献773篇，经共现网络可视化分析得出频次排名前10位的总体关键词和总体关键词形成的14个聚类。频次排名前5位的失语症类型为运动性失语、癔病性失语、经皮质运动性失语、命名性失语和感觉性失语。出现频次≥10次的刺灸法关键词为头针、舌针、体针、电针。频次≥25次的穴位共有16个，“针法-穴位”关键词聚类形成7个针法聚类。近5年爆发性最强的关键词为重复经颅刺激疗法、语言康复训练、针药结合、卒中等。结论: 针灸治疗失语症具有一定的优势，其主要研究热点逐渐形成体系，应通过对已研究的疗法进行更深层次的挖掘，探索出符合针灸特色的失语症转化医学模式。.
