ABSTRACT
Objective:To reveal the research focus of doctoral dissertation of China Academy of Chinese Medical Sciences by information visualization.Methods:Based on the relevant documents from January 1st, 2008 to December 31st, 2018 retrieved by CNKI, through the methods of CiteSpace high-frequency word visualization analysis and co word clustering, the research focus was explored in three time segments, and comparative analysis was carried out.Results:A total of 1 918 literatures were included. The methodology research based on Traditional Chinese Medicine (TCM) syndromes, the application research of data mining technology, and the clinical research of TCM were identified by knowledge atlas as the research hotspots of academic dissertation of China Academy of Chinese Medical Sciences from 2008 to 2018, with good continuity. The disease types of related researcheswere close to the clinical frontier, and the continuity of syndrome and treatment research of coronary heart disease were poor. The number of basic researches represented by TCM syndrome were always lower than that of clinical research. The diagnosis and treatment mode and modern research methods based on the combination of disease and syndrome and the combination of traditional Chinese and Western medicine were gradually deepening in the field of TCM.Conclusions:Interdisciplinary research is a hot topic in the dissertation research of the China Academy of Chinese Medical Sciences. The use of information visualization tools can provide reference for scientific and in-depth exploration of the research direction of TCM.
ABSTRACT
Objective To compare the effect of different body position and length of bed time after lumbar puncture on the postoperative headache.Methods Literatures were searched at home and abroad through the database,and provided comprehensive quantitative analysis to compare the effect of different body position and length of bed time after lumbar puncture on the postoperative headache by the Cochrane collaboration Meta-analysis.Results A total of 20 studies (3 514 patients) were included for Meta-analysis.Mter lumbar puncture for the low supine pillow and the pillow recumbent position,headache incidence rate had no significant difference between the two positions,combined odds ratio (OR) and 95％ confidence intervals were 0.87 (0.41-1.87)(P＞ 0.05);After lumbar puncture to stay in bed for a long time to rest (≥ 4 h) and short time in bed rest (＜1 h),headache incidence rate had no significant difference between the two different time,the combined odds ratio (OR) and 95％ confidence intervals were 0.77 (0.58-1.02)(P ＞ 0.05).Conclusions After lumbar puncture,the occurrence rate of headache is not increased after taking a low pillow lying position or a short time in bed rest (＜1 h).
ABSTRACT
Objective To compare the effect of laminar flow bed in the prevention of hospital infections in patients with leukemia after chemotherapy. Method The Meta-analyses were done on Meta RevMan5.0 by retrieving the domestic databases from January 1999 to January 2014 to look into and compare the hospital infections in leukemic patients using laminar flow beds and common beds, including of the rate of hospital infection, duration of fever, days for antibiotic use, hospital stay. Results A total of 16 papers were included. The Meta analyses showed that the rate of hospital infection in the wards with laminar flow beds was significantly lower than that in the wards with common beds (RR=0.54,95%CI (0.47, 0.62), P<0.01). The fever duration, time for antibiotics use and hospital stay in patients in the wards with laminar flow beds were all significantly shorter than those in the patients in the wards with common beds [WMD=-3.64, 95%CI (-4.83,-2.46);WMD=-4.13, 95%CI (-5.95,-2.32)];WMD=-5.36, 95%CI (-7.52,-3.20);P<0.01,respectively)]. Conclusion Laminar flow beds are effective in preventing hospital infections among acute leukemic patients having undergone chemotherapy.
