A Systematic Review and Meta-Analysis of Xiangsha Liujunzi Decoction in the Treatment of Chronic Gastritis

Background: Chronic gastritis (CG) is characterized by inflammation of the gastric mucosa, which can progress to atrophic gastritis, intestinal metaplasia, and dysplasia. Xiangsha Liujunzi Decoction (XSLJZD), a classic traditional Chinese medicine prescription commonly used to treat digestive system diseases, is widely used to treat CG. Therefore, it is necessary to systematically evaluate the efficacy and safety of XSLJZD in the treatment of CG. Methods: Chinese and English databases were searched, and randomized controlled trials of XSLJZD for the treatment of CG were collected from the establishment of the databases to December 28, 2022. Studies were screened according to inclusion and exclusion criteria. The methodological quality of the included studies was assessed using the risk-of-bias assessment tool in the Cochrane Handbook. Data from the included studies were extracted, and a meta-analysis was performed using Review Manager 5.3 and Stata 15.1. Finally, funnel plots and Egger's tests were used to assess publication bias. Results: Fourteen studies with a sample size of 1434 cases. XSLJZD has more advantages than conventional treatment in the treatment of CG, as it can improve the clinical cure rate, clinical efficacy rate, efficacy rate of endoscopic examination, recurrence rate, and TCM symptom scores, and is relatively safe. Funnel plots and Egger's tests indicated publication bias in the included studies. Conclusion: The results of the meta-analysis showed that XSLJZD has advantages in treating CG compared with conventional treatment and is relatively safe. However, owing to the limitations in the quality and quantity of the included studies, caution is recommended when generalizing and applying these results. Further high-quality studies are needed to confirm these findings.
