[CiteSpace knowledge map of research hotspots and frontiers of Polygalae Radix].

In this study, the Web of Science and China National Knowledge Infrastructure(CNKI) were searched comprehensively for the literature about the research on Polygalae Radix. After manual screening, 1 207 Chinese articles and 263 English articles were included in this study. Excel was used to draw the line chart of the annual number of relevant publications. CiteSpace 6.1.R3 was used for the visual analysis of author cooperation, publishing institutions, keyword co-occurrence, keyword clustering, and bursts in the research on Polygalae Radix. The results showed that the number of articles published in Chinese and English increased linearly, which indicated the rising research popularity of Polygalae Radix. WANG J and LIU X were the authors publishing the most articles in Chinese and English, respectively. Shanxi University of Chinese Medicine and Chinese Academy of Medical Sciences were the research institutions with the largest number of Chinese and English publications in this field, respectively. The institutions publishing the relevant articles in English formed a system with the Chinese Academy of Medical Sciences as the core. According to the keywords, the research hotspots of Polygalae Radix included variety selection and breeding, quality standard, extraction and identification of active chemical components, prescription compatibility, processing, clinical medication rules, and pharmacological mechanism. The research frontiers were the molecular mechanisms of Polygalae Radix and its active components in exerting the protective effect on brain nerve, regulating receptor pathways, alleviating anxiety and Alzheimer's disease, as well as data mining and clinical medication summary. This study has reference significance for the topic selection and frontier identification of the future research on Polygalae Radix.

[Survey of prevention knowledge and behavior of echinococcosis and influencing factors in residents in agricultural and pastoral areas of Maerkang City].

OBJECTIVE: To master the prevention knowledge and behavior of echinococcosis and the influencing factors in residents in agricultural and pastoral areas of Maerkang City, so as to provide the reference for formulating the policy and strategy of echinococcosis prevention and control. METHODS: In April, 2017, 796 residents in agricultural and pastoral areas of Maerkang City were selected by the multi-stage stratified random sampling method, and surveyed with questionnaires. The main questions included the prevention knowledge and related behaviors of echinococcosis. RESULTS: The awareness rate of prevention knowledge of echinococcosis was 70.1% (558/796). The awareness rate was the lowest in the group aged 15 to 25 years. The difference of knowledge awareness rate was statistically significant among the different age groups (χ2 = 16.408, P < 0.01). The knowledge awareness rate of the people with middle school or above educational level was higher than that of the people with primary school or below educational level (χ2 = 4.869, P = 0.027). The knowledge awareness rate of the dog owners was lower than that of the people without a dog (χ2 = 11.384, P = 0.001). The knowledge awareness rate in the people who received the knowledge training of three times or more was higher than that in the people who received the knowledge training of two times or less (χ2 = 11.439, P = 0.003). The logistic regression showed that the age, educational level, training times and dog raising were the main influencing factors. The related behavior survey showed that 32.7% (260/796) of residents did not drink unboiled water, 37.0% (61/165) of dog owners tied the dog, 43.6% (72/165) of dog owners fed the dogs with anthelmintic regularly, and only 10.3% (17/165) of dog owners buried the dog's dung. CONCLUSIONS: The awareness rate of echinococcosis prevention knowledge in Maerkang City should be improved. The health education should be focused on the young people, people with low educational level, and people who have dogs. The behaviors of drinking unboiled water, tying dogs, feeding dogs with anthelmintic regularly, and burying dog' s dung should be advocated.
