RESUMEN
Objective:To explore the characteristics and trends of potential suicide risk among college students in China, as well as the predictive factors for the potential suicide risk subgroups, in order to provide scientific basis for early identification and precise intervention of potential suicide risks.Methods:From 2017 to 2021, a total of 14 653 undergraduate students were selected from 6 universities in Hubei Province through cluster sampling.Data were collected once a year in October after freshmen enrolled (a total of 5 times). Mplus 8.3 and SPSS 26.0 softwares were used for statistics.Latent profile analysis(LPA)was used to analyze the category characteristic of suicide risk in 5 dimensions, and multinomial logistic regression was constructed to analyze the gender and school year effects of suicide risk categories, as well as whether the differences in suicide risk would expand, decrease or maintain over time.Results:(1) According to the fitting indexes of the LPA, the potential suicide risk of college students could be divided into three heterogeneous categories, namely C1 low-risk group (75.6%), C2 helpless high-risk group (3.7%) and C3 personality high-risk group (20.7%). (2) The 2 high suicide risk groups (C2 and C3) had significant gender and grade effects.In terms of gender, female students were significantly less likely to be in the " C3 personality high-risk group" than male students.As the enrollment grade increased, the probability of entering the two high suicide risk groups showed an increasing trend.(3) Interpersonal sensitivity was a significant positive predictor of entry into the " C3 personality high-risk group" ( B=0.150, OR=1.162, 95% CI=1.140-1.185). Paranoid Ideation was a significant positive predictor of entry into the " C2 helpless high-risk group" ( B=0.103, OR=1.109, 95% CI=1.051-1.170). Phobic anxiety was a significant negative predictor of entry into both the " C2 helpless high-risk group" ( B=-0.041, OR=0.976, 95% CI=0.937-1.016)and the " C3 personality high-risk group" ( B=-0.031, OR=0.987, 95% CI=0.965-1.010). (4)Over time, the probability of entering the two high-risk suicide groups(C2 and C3) increased.The proportion of C2 and C3 showed an upward trend, and the proportion of C3 showed a more significant upward trend, with a 10% increase over the past 5 years. Conclusions:The potential suicide risk of college students can be divided into three heterogeneous categories.There are significant differences in the impact of gender, grade of enrollment, and mental health symptoms (interpersonal sensitivity, phobic anxiety, and paranoia ideation) on potential suicide risk among different subgroups.Targeted intervention measures should be taken based on the characteristics of college students in the high-risk group of suicide and should focus on college students with high neurotic personality traits in the high suicide risk group to reduce the occurrence of crisis events.
RESUMEN
OBJECTIVE@#To investigate the current status and further development of Panax genus and 6 important individual species including P. notoginseng, P. quinquefolium, P. vietnamensis, P. japonicus, P. stipuleanatus and P. zingiberensis.@*METHODS@#The bibliometric analysis was based on the Web of Science core database platform from Thomson Reuters. Totally, 7,574 records of scientific research of Panax species published from 1900-2019 were analyzed. The statistical and visualization analysis was performed by CiteSpace and HistCite software.@*RESULTS@#The academic research of Panax species increase promptly. Plant science is the main research field while research and experimental medicine and agricultural engineering will be the further development tendency. Particularly, the discrimination research of P. notoginseng will be the research tendency among Panax species, especially diversity research. In addition, P. vietnamensis deserves more attention in the genus Panax.@*CONCLUSION@#This research provides a reference for further research of the genus and individual species.

OBJECTIVE:To know about the hot point and development tendency of traditional Chinese medicine (TCM) in the nearest 20 years and provide reference for the further study. METHODS:Totally 5 000 papers of cited top 1% with the“TCM”themes in CNKI from 1994 to 2013 were collected. With the indicators of cited times and download times,Excel software analysis function,the CiteSpace citation analysis function and bibliometrics were adopted to statistically analyze the research field,main items,chemical constituents,pharmacological activities,published journals,personnel and units,etc. RESULTS:The papers about TCM research quantity in CNKI were increased exponentially in last 20 years,and might enter the platform period hence-forth;totally 15 main research fields,50 TCM and 60 chemical components/portions with strong activity and development prospect were highly noticed and cited;the study of pharmacological activities was the core and the most active area of TCM research,and mainly related to the major diseases and diseases with TCM advantages;totally 60 papers for highly cited were greater than 500 times,devoting 58.8%highly cited papers;40 authors and units screened from annually top 50 cited papers had wider academic in-fluence. CONCLUSIONS:Analyzing the hot point and development tendency of TCM research in the nearest 20 years based on the CNKI highly cited papers can accurately grasp the industry focus,thereby provide a certain reference and data support for tradition-al Chinese medicine research.

RESUMEN
The paper first summarizes the major trends and chief features in the current development of imaging medicine and then by focusing on such characteristics of modern imaging medicine as a broad base of specialized knowledge, a wide disciplinary span and rapid equipment and technology development, it dwells on the importance of hospital managers doing a good job of personnel cultivation in modem imaging medicine in such aspects as the integration of medicine, engineering and technology, the combination of medicine, education and research, and the awareness of imaging in a larger sense.
RESUMEN
According to the actuality of domestic medical equipment management and its main problems, development tendency of current equipment management are analyzed in four aspects of the norms of medical equipment management standards and details, the expansion of medical equipment information management in whole course, attention to medical engineering disciplines, and strengthening the quality control of medical equipment and application of security technology.
RESUMEN
The development history of Chinese HIS is reviewed,the gap between domestic HIS and international one are compared from the scale of investment and the proportion of technical personnel,and the existing problems in domestic HIS are analyzed.It is suggested that the future tendencies of domestic HIS include the improvement of information standardization,more attention is paid to the construction of HIS,and the modern management should be taken as new objective,etc.[Chinese Medical Equipment Journal,2008,29(2):39-41]
