[Network visual data mining and analysis of literature on electroacupuncture treatment of post-stroke sequelae].

To analyze the optimum stimulating parameters and acupoint combination law of electroacupuncture (EA) treatment of post-stroke sequelae (PSS) through the network visual data mining and analysis of the literature，so as to provide reference for clinical application.The related articles of acupuncture treatment of PSS patients published from January 1, 2005 to December 31, 2021 were collected from databases of CNKI, Wanfang, Weipu（VIP), SinoMed, CHAOXING, DUXIU, PubMed, Ovid, Embase and Cochrane Library. After the articles were screened according to our formulated inclusion and exclusion criteria, a "Clinical Literature Database of EA Treatment of PSS" was established. The SPSS Modeler14.1 software was used for modeling (by using the parameters of EA, types of apoplexy sequelae, names of acupoints, methods of acupoint matching, acupoint-attributed meridians, etc.) and association rule analysis, and the Cytoscape 3.6.0 software was used for data network visualization analysis.A total of 354 articles were collected, including 13 types of PSS, among which the hemi-plegia accounts for the highest proportion (51.13%), followed by depression (17.51%) and dysphagia (14.97%). A total of 228 acupoints are used, with a total frequency-time of 1 690. Among the 8 PSS (hemiplegia, depression, dysphagia, cognitive impairment, urinary incontinence, urinary retention, speech disorders, constipation) with the frequency of application of acupoints greater than or equal to 3, 275 articles are involved, with the frequency of dense wave being the highest (123 times), followed by continuous waves (95 times). The stimulation frequency of EA appears 275 times, with the low frequency being the highest (188 times). For hemiplegia type of PSS, low frequency and continuous waves or dense waves are mostly used, and the high correlation acupoint groups are Zusanli(ST36)/Hegu(LI4), LI4/Quchi(LI11) and ST36/LI11. For depression, low frequency and dense waves are mostly used, and the high correlation acupoint groups are Baihui(GV20)/Yintang(EX-HN3), GV20/Shenting(GV24) and GV20/Neiguan(PC6). For swallowing disorder, the mostly used stimulation parameter is low frequency, and the high correlation acupoint groups are Lianquan(CV23)/ST36/Fenglong(ST40), Tongli(HT5)/Yifeng(TE17)/PC6/ST40, and TE17/HT5/PC6/LI4.EA therapy is frequently used in the treatment of PSS, for which ST36, LI4 and LI11 are most frequently used in the treatment of hemiplegia, with the stimulation parameters being low-frequency and continuous waves or dense waves. For depression, GV20, EX-HN3, GV24 and PC6 are used, with the stimulation parameters being low frequency and dense waves. For dysphagia, CV23, HT5, TE17, PC6, ST36, ST40 and LI4 are employed, with low frequency electrical stimulation.目的：通过对电针治疗脑卒中后遗症(PSS)文献的网络可视化数据挖掘与分析，总结电针治疗PSS的刺激参数和用穴规律，为临床应用提供参考。方法：检索中国知网(CNKI)、万方数据知识服务平台、维普资讯中文期刊服务平台(VIP)、中国生物医学文献服务系统(SinoMed)、超星期刊(CHAOXING)、读秀(DUXIU)及PubMed、Ovid、Embase、Cochrane Library数据库中电针治疗PSS的临床文献。根据纳入、排除标准筛选文献，建立电针治疗PSS的临床文献数据库，运用SPSS Modeler14.1软件建模，进行关联规则分析，利用Cytoscape 3.6.0软件进行网络可视化分析。结果：共纳入354篇文献，涉及PSS病种13个，其中偏瘫占比最高(51.13%)，其次为抑郁症(17.51%)和吞咽障碍(14.97%)，共涉及穴位228个，总频次1 690次。在使用穴位频次≥3的8个PSS病种(偏瘫、抑郁症、吞咽障碍、认知障碍、尿失禁、尿潴留、言语障碍、便秘)中，涉及波形275次，其中疏密波使用频次最高(123次)，其次为连续波(95次)；涉及频率275次，其中低频使用频次最高(188次)；偏瘫多选用低频连续波或疏密波，高关联穴组为足三里/合谷、合谷/曲池、足三里/曲池；抑郁症多选用低频疏密波，高关联穴组为百会/印堂、百会/神庭、百会/内关；吞咽障碍多选用低频，高关联穴组为廉泉/足三里/丰隆、通里/翳风/内关/丰隆、翳风/通里/内关/合谷。结论：电针治疗PSS的病种众多，其中电针治疗偏瘫多选足三里、曲池、合谷，刺激参数选择低频连续波或疏密波；抑郁症多选百会、印堂、神庭、内关，刺激参数选择低频疏密波；吞咽障碍多选廉泉、通里、翳风、内关、足三里、丰隆、合谷，刺激频率选择低频。.
