Efficacy and safety of Weifuchun tablet for chronic atrophic gastritis: A systematic review and meta-analysis.

BACKGROUND: Chronic atrophic gastritis is a significant premalignant lesion of gastric carcinoma. There is a great need to prevent the progression to gastric carcinoma through early intervention and treatment for chronic atrophic gastritis. Weifuchun, a famous Chinese patent drug, has been widely used for chronic atrophic gastritis in China. However, it remains unclear whether Weifuchun is effective for atrophic gastritis. OBJECTIVE: To determine the effectiveness and safety of Weifuchun for chronic atrophic gastritis. METHODS: We systematically retrieved seven databases (Cochrane Library, EMBASE, PubMed, China National Knowledge Infrastructure, Wanfang database, Chinese Scientific Journals Database, and Chinese Biological Medical Database) from their inception to October 5, 2022. Methodological quality was examined using the Cochrane Risk of bias tool. We also used RevMan 5.4 software for statistical analysis to examine the effectiveness and safety of Weifuchun. RESULTS: Fifteen studies with 1,488 patients were enrolled in this meta-analysis. The study indicated that Weifuchun was more effective (RR 1.52; 95% CI 1.41, 1.63; p<0.00001) than Western medicine and other Chinese patent medicine. In addition, Weifuchun was more effective in improving gastric mucosal under gastroscopy, improving histopathologic changes of gastric mucosal, and inhibiting Helicobacter pylori. However, no significant difference in safety was examined between Weifuchun and the control group (RR 2.83; 95% CI 0.85, 9.38; P = 0.09). CONCLUSIONS: The meta-analysis revealed a significant statistical difference with Weifuchun in effectiveness compared to the control group. However, there was no significant difference in safety. Thus, more high-quality clinical studies are needed in the future. TRIAL REGISTRATION: Registration number CRD42022365703.

Efficacy and safety of umbilical therapy with the traditional Chinese medicine formulation Lishui Xiaogu cataplasm for cirrhotic ascites: protocol for a randomized controlled trial.

BACKGROUND: Ascites is one of the most common complications of cirrhosis. Umbilical therapy with traditional Chinese medicines has been increasingly prescribed to treat cirrhotic ascites. However, high-quality evidence from clinical trials supporting such application of traditional Chinese medicines remains limited. Therefore, we designed a clinical trial to evaluate the efficacy and safety of umbilical therapy with the Lishui Xiaogu cataplasm formulation applied to treat cirrhotic ascites. METHODS/DESIGN: This ongoing study is a double-blind, randomized, parallel, placebo-controlled trial. A total of 82 patients will be recruited and randomly assigned to either a treatment group or a placebo group, in a 1:1 ratio. The treatment group will receive umbilical therapy with the Lishui Xiaogu cataplasm plus red light irradiation along with conventional treatment; the placebo group will receive umbilical therapy with a placebo cataplasm plus red light irradiation along with conventional treatment. Interventions for both groups will be administered once daily for up to 10 days, with a 30-day follow-up after the last treatment. The primary efficacy measurement will be ascites depth. Secondary efficacy measurements will include abdominal perimeter, weight, urine volume, the symptomatic score of traditional Chinese medicine, and the Chronic Liver Disease Questionnaire. Adverse events will also be reported. DISCUSSION: This randomized trial will be the first rigorous study designed to evaluate the efficacy and safety of umbilical therapy with Lishui Xiaogu cataplasm applied for cirrhotic ascites.

Modeling and simulating dynamics of complete- and poor-response chronic hepatitis B chinese patients for adefovir and traditional chinese medicine plus adefovir therapy.

ChiCTR-TRC-11001263 study was the first large-scale double-blind randomized placebo-controlled traditional Chinese medicines (TCMs) and adefovir (ADV) antihepatitis B virus (HBV) infection trial in the world. A total of 560 hepatitis B e antigen- (HBeAg-) positive Chinese patients with chronical HBV were randomly classified, in 1 : 1 ratio, into two groups: experimental group (EXG) receiving TCMs + ADV and controlled group (CTG) receiving ADV + TCM-placebo treatment for 48 weeks. This paper introduces two models to model and simulate the evolutions of dynamics for the complete-response patients and the poor-response patients in EXG and CTG, respectively. The stimulated mean HBV DNA and alanine aminotransferase (ALT) levels were close to the patients' experimental data. Analysis and simulations suggest that the activated patients' immune functions by TCMs + ADV may not only clear infected hepatocytes, but also clear HBV, which made the complete-response patients' mean serum HBV DNA levels in EXG reduce rapidly 12 weeks' earlier than the ones in CTG. One can assume that both the TCMs and ADV have the function of preventing complete-response patients' infected hepatocytes from being injured by cytotoxic T lymphocytes (CTLs); the patients' activated immune cells may also block HBV replications.
