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.

Long-term effect of strengthening management under transcranial Doppler monitoring on patients with severe craniocerebral injury during hospitalization / 中华神经医学杂志

Objective:To investigate the long-term influence of strengthening management under transcranial Doppler (TCD) monitoring in prognosis of patients with severe craniocerebral injury during hospitalization.Methods:According to the randomized parallel controlled clinical trial, from June 2016 to December 2019, 84 patients from First Ward and Neurological Intensive Care Unit of Department of Neurosurgery, Xianyang First People's Hospital, 12 patients from Third Surgical Department, Chinese Medicine Hospital of Linqu County, and 10 patients from First Brain Surgical Department, Chinese Medicine Hospital of Linqu County were randomly divided into control group and observation group ( n=53). Patients in the control group used postoperative management plan proposed by BTF Guidelines for Severe Traumatic Brain Injury (4 th Edition) , and patients in the observation group accepted strengthening management plan formulated by our research group on the basis of treatment in the control group: TCD monitoring of middle cerebral artery and extracranial internal carotid artery was daily used to record or calculate blood pressure, systolic peak velocity, end-diastolic velocity, vascular resistance index, mean arterial pressure, noninvasive cerebral perfusion pressure, cerebral vascular resistance, noninvasive intracranial pressure, and Lindegaard index; and individualized strengthening management was given according to the monitoring indicators. The average length of hospitalization, proportion of subdural effusion during hospitalization, and Glasgow outcome scale-extended (GOSE) scores at 6 months after injury were compared between the two groups. Results:The average length of hospitalization ([20.7±4.2] d) and proportion of subdural effusion during hospitalization (9.4%) in the observation group were significantly lower than those in the control group ([28.2±4.4] d, 20.7%, P<0.05). The GOSE scores at 6 months after injury (5.5±1.2) were significantly higher than those in the control group (3.2±0.9, P<0.05). Conclusion:Strengthening management under TCD monitoring during hospitalization can more effectively improve the long-term prognosis of patients with severe craniocerebral injury.

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.

Associations of low triiodothyronine syndrome and Glasgow coma scale scores with mortalities and recurrence in hypertensive intracerebral hemorrhage / 中华神经医学杂志

Objective Both flee triiodothyronine (FT3) level and Glasgow Coma scale (GCS) scores have been separately described as prognostic predictors for mortality in hypertensive intracerebral hemorrhage (HICH).This study is conducted to investigate the relationship and prognostic impact of low-T3 syndrome and GCS in HICH patients.Methods Two hundred and thirty patients with HICH,admitted to our hospital from January 2015 to January 2016,were chosen and performed thyroid hormone levels examination (FT3,FT4 and thyroid stimulating hormone [TSH] 3).According to the thyroid hormone results,these patients were divided into low T3 group I (FT3＜3.1 pmol/L,normal TSH level) and normal thyroid function group (normal FT3,FT4 and TSH levels).According to best cut-off levels defined by receiver operating characteristic (ROC) curve,these patients were divided into low GCS scores group (GCS＜7.5) and high GCS scores group (GCS＞7.5),and low T3 group Ⅱ (FT3＜2.85 pmol/L) and high T3 group (FT3＞2.85 pmol/L).Telephone follow-up was performed every 6 months,and using death or re-bleeding during follow-up period as end point of the event,prognostic values of FT3 level and GCS scores defined by ROC curve in mortality and re-bleeding rote were recorded;survival rate of these patients were analyzed by Kaplan-Meier curves and compared between each two groups;multivariate Cox regression was used to analyze the relations of FT3 level and GCS scores with mortality and re-bleeding rate.Results As compared with normal thyroid function group,low T3 group Ⅰ had significantly higher re-bleeding rate,percentage of patients with blood loss＞30 mL,and rate of breaking into the ventricles,and statistically lower GCS scores at admission and FT3 level (P＜0.05);the mean age in patients of low T3 group Ⅰ was significantly elder than that in patients of normal thyroid function group (P＜0.05).ROC results indicated that the sensitivity and specificity of GCS scores in predicting mortality and re-bleeding rate were 63％ and 73％,and those of FT3 level were 45％ and 73％.Kaplan-Meier curves showed that both low GCS group and low T3 group Ⅱ had significantly increased mortality and re-bleeding rate as compared with high GCS group and high T3 group (P＜0.05).Unified prediction results indicated that patients from low T3 and low GCS group had significantly higher mortality and re-bleeding rate as compared with patients from low T3 and high GCS group,high T3 and low GCS group,and high T3 and high GCS group (P＜0.05).Conclusion Low T3 syndrome is common in patients with HICH;FT3 level and GCS scores appear to be important predictors for mortality and recurrence in patients with HICH.
