Objective:To analyze the group heterogeneity of different types of self-management ability of patients with nonalcoholic fatty liver disease (NAFLD) through potential category analysis, and to explore the differences of nursing interventions among different types of people, so as to provide reference for intervention research.Methods:From March to August 2021, NAFLD patients undergoing physical examination and hospitalization in the First Affiliated Hospital of Xinjiang Medical University were selected as the research object by convenience sampling. The General Information Questionnaire, Health Promoting Lifestyle Profile-Ⅱ (HPLP-Ⅱ) and Self-management Behavior Scale for Patients with NAFLD were used to investigate the patients, and the height and weight of the patients were also measured. A total of 1 189 questionnaires were distributed and 1 124 valid questionnaires were recovered.Results:Self-management ability of NAFLD patients were divided into five types, including good self-management group (32.03%) , lack of self-management-medium level psychological cognition group (23.84%) , lack of health promoting behavior group (11.30%) , lack of disease-cognition-life management group (27.31%) , serious lack of self-management-medium level stress group (5.52%) . Taking the good self-management group as a reference, the results showed that age, marital status, occupation, education level, average monthly income, treatment methods, smoking, body mass index (BMI) , sleep quality, and concomitant diseases were the influencing factors that caused the potential category differences of self-management behavior in NAFLD patients, and the differences were statistically significant ( P<0.05) . Conclusions:Each potential category of NAFLD patients' self-management ability has specificity, which suggests that the formulation of nursing interventions for NAFLD patients in the future should be based on the heterogeneity of various types of groups, so as to improve the effectiveness of self-management intervention.

Objective:To analyze the research frontiers and trends in the research field of Tongxieyao Prescription.Methods:Research literature about Tongxieyao Prescription was retrieved from CNKI, VIP, Wanfang Data, SinoMed and Chinese Medical Journal Full Text Database from January 1, 2002 to July 13, 2022. NoteExpress 3.0 software was used to merge and remove the weight, and VOSviewer 1.6 and CiteSpace 5.8 software were used to analyze the author, research institution, key words and a knowledge map was drawn.Results:A total of 1 309 articles were included. The overall number of publications in this field was on the rise. Wang Jianwei of Heilongjiang University of Chinese Medicine (16 articles) published the most papers, and there was a lack of communication and cooperation between the author's teams. The publishing institutions were mainly TCM universities, and there were few influential institutions. Through co-occurrence and clustering analysis of keywords, it was found that the keywords in the field of Tongxieyao Prescription mainly focused on diarrhea, irritable bowel syndrome, gut microbiota, brain gut peptides, clinical efficacy, and other words. Keyword highlighting showed that gut microbiota was a research hotspot.Conclusions:The research on Tongxieyao Prescription focuses on the treatment of irritable bowel syndrome and ulcerative colitis with Tongxieyao Prescription. Its mechanism includes inflammatory factor pathway, immune pathway, intestinal flora and brain-gut axis regulation. At present, the prospect of Tongxieyao Prescription is bright, and basic research is active. It is still necessary to strengthen cooperation among scholars from various institutions to facilitate in-depth research progress.
