ABSTRACT
Objective:To summarize the hotspots and developmental status of non-suicidal self-injury research by clustering and co-occurrence to the literature on non-suicidal self-injury on the basis of Cite Space, and in order to provide references for future research and intervention.Methods:Non-suicidal self-injury literature included in the Web of science core collection from January 1975 to August 2020 was searched, and the included literature was visualized and analyzed using Cite Space 5.5.R2 knowledge mapping software.Results:A total of 974 articles were retrieved, and the number of articles published showed an increasing trend year by year, mostly in developed countries. The country with the highest cumulative number of articles was the United States, with a total of 412 articles, and the first organization was Katholieke Univ Leuven, with a total of 42 articles. Key words co-occurrence and clustering showed that the current research focus was on adolescents, suicidal behavior, dialectical behavior therapy, and borderline personality disorder. The most cited literature was by Muehlenkamp.Conclusions:Non-suicidal self-injury research has developed rapidly in recent years. At present, non-suicidal self-injury population, related intervention measures, screening and evaluation tools, Meta-analysis and risk factor analysis are its research frontiers and hot spots.
ABSTRACT
Objective To explore the expression and significance of hsa-miR-181a (miR-181a) in can-ceration progression of endometrial carcinoma. Methods A total of 75 formalin-fixed paraffin-embedded tissue specimens were studied in this study , of which , 13 were normal endometrium , 18 were endometrial hyperplasia , 44 were endometrial carcinoma. After total RNA had been extracted , real-time PCR was applied to detect the ex-pression level of miR-181a in endometrial tissue in each group. Results miR-181a expression in formalin-fixed paraffin-embedded tissue specimens can be detected. Expression of miR-181a in endometrial carcinoma was high-er than that in endometrial hyperplasia , its expression in endometrial hyperplasia was also higher than that in normal endometrium, and the difference was statistically significant (P < 0.05). The expression of miR-181a in endometrial carcinoma was associated with FIGO stages (P < 0.05). Conclusion The up-regulation of miR-181a expression in women with endometrial carcinoma may play the role of oncogenes. Abnormal expression of miR-181a is probably associated with the occurrence and development of endometrial carcinoma.
