Effectiveness and safety of Chinese medicine combined with omeprazole in the treatment of gastric ulcer: A protocol for systematic review and meta-analysis

Abstract

Background:Gastric ulcer (GU) is a common digestive system disease, and the main clinical manifestations are nausea and epigastric pain. In recent years, due to increased life pressure, unhealthy eating habits and environment, the incidence of gastric ulcer has increased year by year. Because the disease has a long treatment cycle and is prone to relapse, if it cannot be controlled in time, it can cause the disease to prolong, affect the daily life and health of the patient, and even cause complications such as upper gastrointestinal bleeding, ulcer perforation, and pyloric obstruction. Helicobacter pylori infection is one of the main causes of GU. Clinically, the curative effect of western medicine or traditional Chinese medicine cannot reach the ideal level, so in recent years, the combination of traditional Chinese and western medicine has been highly praised. The aim of this systematic review is to evaluate the effectiveness and safety of Chinese medicine combined with omeprazole for GU.Methods:The data and information will be retrieved from the databases of PubMed, Embase, Cochrane Library, CNKI, VIP, and Wanfang data. Literature search is limited to Chinese and English. The search time range is from the establishment of the database to April 7, 2021. The search strategy uses a combination of subject terms and free words to search. In order to avoid omissions, the search scope includes subject terms, keywords, or full text. Two reviewers will independently exclude substandard articles and extract eligible data. The risk of bias will be assessed using the Cochrane Handbook 5.1.0 for Systematic Reviews of Interventions. RevMan 5.3 will be used for systematic review and meta-analysis. This protocol will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement, and the systematic review will be reported with the PRISMA statement.Results and conclusion:The efficacy and safety of Chinese medicine combined with omeprazole for the treatment of GU will be evaluated, and the conclusion will be published to provide medical evidence for a better clinical decision of patients with GU.
