CiteSpace-based visualization analysis of domestic and foreign researches on post-traumatic stress disorder in recent five years / 四川精神卫生

ObjectiveTo understand the research status of post-traumatic stress disorder （PTSD） at home and abroad in recent five years， and to grasp the research frontiers and hot spots in this field. MethodsTwo electronic databases， Web of Science and China National Knowledge Infrastructure （CNKI）， were retrieved for the literature published from January 1， 2017 to December 31， 2021. A total of 8 505 literatures were included， then the visualization analysis of the number of publications， authors， countries， institutions and keywords was conducted based on Microsoft Excel and CiteSpace software. Results① The number of publications in domestic and foreign showed an increasing trend in recent five years. ② In foreign literature， the top five countries in terms of the number of publications were the United States， the United Kingdom， China， Australia and Canada， with Canada having the highest centrality （0.18）. ③ Both domestic and foreign research institutions were dominated by universities. ④ In terms of the number of articles published， the top three foreign scholars were Bryant RA， Ressler KJ and Greenberg N， and the top three Chinese scholars were Wu Xinchun， Li Yuefeng， Yan Xingke and Zhang Guiqing （tied for the third place）. Compared with foreign authors， the number of articles published by Chinese scholars was relatively small. ⑤ In terms of research keywords， PTSD and depression were of more concern in both domestic and foreign. ConclusionIn recent five years， PTSD has been a hot topic at home and abroad， with both domestic and international studies focusing on PTSD and depression， and strengthening international exchanges may help promote progress in the field of PTSD research.

Methodological quality assessment of systematic reviews or Meta-analyses of intervention randomized controlled trials published in the Sichuan Mental Health / 四川精神卫生

ObjectiveTo evaluate the methodological quality of systematic review / Meta analysis （SR/MA） of intervention randomized controlled trial （RCT） published in the Sichuan Mental Health. MethodsThe literature databases such as Wanfang Data， China National Knowledge Infrastructure （CNKI）， VIP Database for Chinese Technical Periodical （VIP） and Chinese Biomedical Literature Database （CBM） were searched for the SRs/MAs of intervention RCTs published in the Sichuan Mental Health from the initial issue to the issue published on 31 June 2021. Then the methodological quality of eligible SRs/MAs were assessed using A Measurement Tool to Assess systematic Reviews 2 （AMSTAR 2）. ResultsThe literature search yielded 24 full-text articles， and the mean AMSTAR 2 score of the included SRs/MAs was （5.21±3.63） with a range from 1 to 11. The total AMSTAR 2 score for SRs/MAs showed difference in terms of the publication date prior to or later than the publication of AMSTAR-2 tool （t=-5.499）， number of authors ≤ 2 or ≥ 3 （t=-6.736）， with or without funding support （t=3.329） and author unit nature （F=7.827）， with statistical significance （P<0.01）. All selected studies had deficiencies on explicit statement of a priori design and registrations， list of excluded studies and reasons for exclusion， sources of funding for the research in systematic review， potential conflicts of interest statement， and funding information of the systematic review. ConclusionThe methodological quality of SRs/MAs of intervention RCTs published in the Sichuan Mental Health varies widely， After the release of AMSTAR 2， the methodological quality has improved， but the report still needs to be further standardized to provide high-quality evidence-based evidence.

Simultaneous determination of six major isosteroidal alkaloids in Beimu by UPLC-ELSD / 中国中药杂志

An UPLC method was established for the direct determination of six major bioactive isosteroidal alkaloids, namely peimisine, imperialine, sipeimine-3-D-glucoside, verticinone, verticine and hupehenine from the bulbus of Fritillaria(Beimu), a commonly used antitussive traditional Chinese medicinal(TCM) herb. An Acquity UPLC~(TM) CSH C_(18) column(2.1 mm×100 mm, 1.7 μm) was used for all analysis. The investigated six compounds were all separated with gradient mobile phase consisting of 0.02% diethylamine-water-methanol at a flow rate of 0.3 mL·min~(-1). The temperature of sample manager was set at 20 ℃. Drift tube temperature was 45 ℃, and spray parameter was 40% with injection volume of 1 μL. Then, the further quality assessment of Beimu was carried out by cluster analysis(CA) and principal component analysis(PCA). The investigated all had good linearity(r≥0.998 9) over the tested ranges. The method is simple, accurate and reproducible, and can be used for determining the content of six major bioactive isosteroidal alkaloids.

Decipherment of herb medicine Nanwuweizi and Wuweizi in Chinese ancient literature / 中国中药杂志

Nanwuweizi( Schisandrae Sphenantherae Fructus) and Wuweizi( Schisandrae Chinensis Fructus) have long-term history of use as common traditional Chinese medicines since the Eastern Han Dynasty( AD.25-220 year).However their information are always confused in ancient literature because they were both used as " Wuweizi". Nanwuweizi and Wuweizi are faced with problems such as confused distribution of producing areas,unclear source plants and efficacy characteristics,which limit modern resource development and application. Based on ancient literatures of materia medica,this study conducted a systematic review from several aspects,i.e. the name,distribution of producing areas,source plants,efficacy characteristics and processing of the two medicines in ancient time. This study clarified five main aspects,as following,ancient production areas and corresponding modern distribution areas; source plants used for medicinal purposes in ancient time; application period and application scope; efficacy characteristics in clinical application;processing method. This study provides a reference for evaluating the quality and for their clinical application and reasonable development of Nanwuweizi and Wuweizi.
