Objective: To introduce co-word analysis into the analysis of the current research status of childhood tuberculous meningitis, to compare the similarities and differences in research topics of the field in China and abroad over the past decade, and to discover the advantages and weak links in the study field in China.
Methods: PubMed, CNKI, VIP, and Wanfang Data were searched for the articles which met the inclusion criteria. Ucinet 6.0 and Netdraw were used for co-occurrence analysis, and the co-article relationship between high-frequency key words was visualized.
Results: A total of 226 articles abroad and 186 Chinese articles on childhood tuberculous meningitis were obtained. The figures for co-occurrence analysis of high-frequency key words in research articles on childhood tuberculous meningitis in China and abroad were successfully plotted. Compared with the studies in China, the studies abroad were more sophisticated and well-developed, with more studies on drug-resistant tuberculosis, the relationship between tuberculosis and AIDS, and the epidemiology of tuberculosis. The key words listed in the studies abroad were more standard. The studies in China on childhood tuberculous meningitis concentrated on vaccination and nursing.
Conclusions: In general, the studies on childhood tuberculous meningitis in China and abroad have the same directions. The studies abroad have a complicated network and use more standard key words. The studies on childhood tuberculous meningitis are well conducted in China. However, more studies are needed for drug-resistant tuberculosis, the relationship between tuberculosis and AIDS, and the epidemiology of tuberculosis in future.
目的: 将共词分析引入儿童结核性脑膜炎的现状研究, 比较近10年该研究领域国内外研究主题的异同, 寻找中国该研究领域的优势和薄弱环节。
方法: 检索Pubmed、中国知网、维普、万方数据库并纳入符合研究标准的文献, 利用Ucinet6.0及Netdraw绘制共现分析图, 将高频关键词之间的共篇关系可视化。
结果: 共查得儿童结核性脑膜炎国外相关研究文献226篇, 国内研究文献186篇, 成功建立国内外儿童结核性脑膜炎研究论文高频关键词的共现分析图。国外相关研究较国内更为丰富与充分, 其在耐药结核、结核与艾滋病、结核流行病学研究方面多于国内研究, 关键词也更为规范; 国内研究则更注重结核的预防接种、护理方面的研究。
结论: 国内外关于儿童结核性脑膜炎的研究总体方向基本相同, 国外文献的网络图更为复杂, 主题词的使用更为规范。中国儿童结核性脑膜炎学科发展处于良好状态, 未来需在耐药结核、结核流行病学、结核与艾滋病的关系等方面进行更多的研究。
