ABSTRACT
Objective To study the development of research about benign paroxysmal positional vertigo (BP-PV) in China and summarize certain characteristics and hot spots ,so as to provide a basis and direction for further relevant research .Methods CNKI ,CQVIP and wanfang database were used to search relevant literatures published before 2015 .The period sequence ,journal distribution ,productive authors ,research institutions ,high -frequent key words and hot spots were analyzed through bibliometric method and visualization method .Results There were 922 literatures about BPPV research from 1981 to 2015 in China ,involving 2021 authors and 309 research institu-tions ,published in 297 kinds of journal .The literature quantity showed a gradual upward trend on the whole and journals were widely distributed ;core journal group had not yet formed .Top 13 journals (4 .38% ,13/297) had published 292 relevant literatures (31 .67% ,292/922) ,major journals were relatively concentrated ;top 17 authors had published 222 relevant literatures (24 .08% ,222/922) ,top 12 research institutions had published 137 relevant literatures (14 .86% ,137/922);high productive authors mostly came from high productive authority .Through an analysis of keywords ,it is found that BPPV researches mainly focus on pathogenesis ,diagnostic method and treat-ment .New directions have emerged in recent years ,like comparative analysis of drug treatment and manual reduc-tion ,study on the secondary BPPV of sudden deafness and Meniere'sdisease .Conclusion The publishing of 2016 re-vised edition of the guidelines for BPPV diagnosis and treatment will further deepen relevant researches ;literature quantity is expected to continue to grow ;study on the secondary BPPV of sudden deafness and Meniere's disease will be a focus .
ABSTRACT
Meridian theory plays an important role in the guidance of clinical practice of acupuncture and moxibustion. Since the publication of(), the meridian theory has been developed. In the paper, in view of complex science, the topological properties of acupoint-symptom network were analyzed quantitatively by taking acupoint as node and indication as the connection, such as high clustering coefficient and the small world effect. It was the first time to give the abstraction for the topological proof of the high efficiency information transmission property of acupoint-symptom network meridian system at different times. Its quantitative and digitalized significance was analyzed on the development of meridian theory under the complex scientific background so as to provide a new thought and method for the study of meridian theory and acupuncture modernization.
