Banxia Xiexin Decoction in the treatment of chronic atrophic gastritis

BACKGROUND: Chronic atrophic gastritis (CAG) is a common digestive disease. Without active treatment, it may induce gastric cancer. Western medicine has a certain effect on chronic atrophic gastritis, but there are many adverse reactions after long-term medication, and the disease is prone to relapse after treatment, which will affect the health and life of patients. Traditional Chinese medicine has obvious advantages in the treatment of chronic stomach diseases with reliable effect. A number of clinical data have also confirmed that Banxia Xiexin decoction has significant effect in the treatment of chronic atrophic gastritis, but there is no evidence of evidence-based medicine. Therefore, this study aims to explore the clinical efficacy and safety of Banxia Xiexin decoction in the treatment of chronic atrophic gastritis by means of systematic evaluation. METHOD: Databases including PubMed, The Cochrance Library, Embase, Web of Science, CNKI, VIP, and Wanfang were searched by computer. Besides, Baidu Scholar and Google Scholar were manually searched, and all randomized controlled trials of Banxia xiexin decoction for the treatment of chronic atrophic gastritis were collected. The retrieval time was from the establishment of the database to July 31, 2020. After 2 reviewers independently screened the literature, extracted the data and evaluated the bias risk of the included study, RevMan5.3 software (developed by the UK's International Cochrane Collaboration) was used to analyze the data. RESULTS: In this study, the effectiveness and safety of Banxia Xiexin decoction for the treatment of chronic atrophic gastritis were evaluated by the clinical efficiency, traditional Chinese medicine syndrome score (traditional Chinese medicine syndrome score), quality of life score, gastrin level, epidermal growth factor, eradication rate of helicobacter pylori and incidence of adverse reactions. CONCLUSION: This study will provide reliable evidence for the clinical application of Banxia Xiexin decoction in the treatment of chronic atrophic gastritis. ETHICS AND DISSEMINATION: The private information from individuals will not be published. This systematic review also will not involve endangering participant rights. Ethical approval is not required. The results may be published in a peer-reviewed journal or disseminated in relevant conferences. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/7K6QW.
