Bibliometric analysis of literature regarding ostomy research based on the Web of Science database

Objective： To analyze the literature status and research hotspots of Science Citation Index （SCI）-related ostomy in the world and to provide references for scientific research and clinical work in the stoma care field. Methods： Based on the Web of Science core database and its own analysis function, HistCite analysis software and Excel were used to study the published research about ostomy patients. Results： A total of 1,262 articles were published between 1910 and 2016 with the authors from 48 countries and regions, 1,347 research institutions, published in 321 journals, with 4,048 first authors and coauthors; globally, there was a trend of slow growth in the number of authors every year. The study in the USA was absolutely in the lead position, and Canada and Turkey were more active. China＇s circulation volume was the 15th in the world. The periodical that published most often was the Journal of Wound Ostomy and Continence Nursing. The most interdisciplinary surgical studies were surgery and nursing, where these should be considered important. The most prolific author in the field was ＂Grant＂, and the highest cited article was entitled as ＂Living with a stoma： a review of the literature＂. Conclusions： The related research of global stoma is constantly developing. The research hotspot is nursing before and after stoma surgery. China and the USA are leading countries in research. They should follow the recent trend to improve the depth and breadth of the research in the field.

Analysis of the Causes of Cyanobacteria Bloom:A Review

Among water blooms,cyanobacteria bloom occurs over the widest range and is much more harmful than other blooms.Its occurrence in inland water bodies is affected by many factors,such as meteorology,hydrology,and human activities.Therefore,the study of the causes of cyanobacterial bloom has become a major focus of scholars.The China Knowledge Network Journal Database contains 143 papers from China and abroad from the years 2004 to 2019 that are relevant to the study of cyanobacteria bloom.We begin by analyzing keywords in these studies and creating a keyword distribution map which indicates the factors related to the blooms.Based on parameters such as the frequency of words appearing in the text,the full text of each of the 143 papers is analyzed to form a word cloud created by a program written in Python language.After irrelevant terms are eliminated,the word cloud map can reveal potential factors that were not identified by keywords alone.After completing this macro analysis,we examined approximately 100 related papers from the China Knowledge Network Journal Database and Web of Science Database published from 2014 to 2019.Finally,we summarize the main reasons for the outbreak of water blooms.The factors causing blooms can be divided into natural factors and human factors.Among the natural factors are illumination,water temperature and nutrient salt conditions.The human factors are generally related to large-scale water conservancy projects.This paper analyzes and summarizes these factors,and provides a reference to aid in the prevention and treatment of algal blooms.The information in the paper has a certain practical significance for the protection of water environments.
