OBJECTIVE:To provide reference for rational use of drugs for gastrointestinal ulcer. METHODS:The drug use for gastrointestinal ulcer in outpatient department of our hospital during 2013-2015 was analyzed retrospectively in respects of drug name,consumption sum,DDDs,DDC,single/multiple diseases prescription,therapeutic efficacy,rationality of presoription,etc. RESULTS:A total of 8 kinds of drugs use for gastrointestinal ulcer in outpatient department of our hospital during 2013-2015, among which the consumption sum and DDDs of Omeprazole capsule and Rabeprazole capsule increased rapidly,and their DDC were the higher others;those of other drugs kept stable. The proportion of acid-inhibitory drugs in single disease prescriptions was lower than in multiple diseases prescriptions,while that of antiacid was higher than in multiple diseases prescriptions,with statisti-cal significance (P<0.05). The total effective rate of patients with gastrointestinal ulcer gradually increased from 77.98% to 82.68% in outpatient department of our hospital during 2013-2015,there was statistical significance between 2015 and 2013(P<0.05);the proportion of irrational prescriptions decreased from 5.01% to 2.12% year by year,with statistical significance among those years (P<0.05). CONCLUSIONS:Omeprazole is the first choice for gastrointestinal ulcer in outpatient department of our hospital with good therapeutic efficacy. There still are some irrational drug use in prescriptions,and clinicians should pay attention to those situations.

BACKGROUND:In recent years,the development of liver organoids has made it a hot spot in the field of international liver disease research,but there is still no article on the bibliometric analysis of liver organoids. OBJECTIVE:To explore the hot trends in liver organoids in the last 20 years based on bibliometrics and visualization analysis. METHODS:We searched the articles about liver organoids in the Web of Science Core Collection from January 1,2002 to November 12,2022.Origin,Office,and CiteSpace software were used for bibliometrics and visualization analysis.We statistically analyzed the number of annually published articles,countries,institutions,authors,journals,and keywords of the articles by generating charts. RESULTS AND CONCLUSION:The number of articles,citation frequency,institutions and personnel involved in the research about liver organoids showed an overall upward trend in the last 20 years,indicating that the field was growing rapidly and attention was increasing.The USA had published the most papers and had the strongest influence in this field.Although it had invested a lot of time and energy,the number of papers published by a single research institution in the USA was not the highest among many research institutions.China was second only to the USA in the number of publications,with the Chinese Academy of Sciences and Fudan University leading the list.Utrecht University in the Netherlands was the institution with the most publications.Clevers H was the author with the highest number of articles.The article with the highest co-citation frequency was"Long-term culture of genome-stable bipotent stem cells from adult human liver".The main fields of study for liver organoids were Molecular Science,Biology,and Immunology.The most frequently occurring keywords were stem cell,in vitro,and culture.The research hotspots in the liver organoids field were mainly focused on in vitro stem cell three-dimensional culture,differentiation and gene expression.
