BackgroundHepatic fibrosis is a health challenge due to the absence of satisfactory therapy, especially at the cirrhosis stage. Dahuang Zhechong pill (DHZCP)-based therapy is reportedly a successful treatment for hepatic fibrosis and is even beneficial for the treatment of cirrhosis. Hence, a systematic review and clinical evidence assessment of DHZCP-based therapy should be performed, and clinical recommendations based on its efficacy for the treatment of hepatic fibrosis should be generated. With respect to potential indicators, the comparative value of the hepatic function, spleen thickness, and portal vein internal diameter should be evaluated.Materials and methodsPubMed, the Excerpta Medica Database, the Cochrane Library, the Web of Science, the WanFang Database, the Chinese Scientific Journal Database, and the Chinese National Knowledge Infrastructure database were searched to identify clinical trials. Three subgroup analyses were performed based on the stage of disease, medication use, and the course of treatment. Statistical analyses were performed using Review Manager 5.4.ResultsA total of 18 studies including 1,494 patients were evaluated. The DHZCP-based therapy was effective in reducing the plasma levels of hyaluronic acid, and laminin, procollagen III, and IV collagen were also reduced irrespective of the hepatitis stage or the presence of hepatic cirrhosis. Abnormalities in alanine aminotransferase, aspartate aminotransferase, albumin, and total bilirubin were reversed. A 6-month course of treatment was the most beneficial DHZCP-based therapy regimen. Alanine aminotransferase improvement was more obvious in patients with cirrhosis, and alanine aminotransferase was reduced significantly in patients with hepatic cirrhosis. With respect to pharmacological mechanisms, DHZCP-based therapy could inhibit hepatic stellate cell growth and activation, reduce inflammation, and prevent extracellular matrix formation. Hepatic portal hypertension and splenomegaly were ameliorated significantly in the DHZCP-based therapy group.ConclusionDahuang Zhechong pill-based therapy has demonstrated efficacy as a treatment for hepatic fibrosis and cirrhosis. A 6-month course of treatment is the recommended option for DHZCP-based therapy in clinical practice. The combination of DHZCP-based therapy and entecavir is a favorable treatment for hepatic cirrhosis.

Ulcerative colitis is a chronic and relapsing inflammatory bowel disease without satisfactory therapy available recently. Renshen Baidu powder (RSBDP) is a classic Chinese medicinal formula used since Chinese Song dynasty and has been proven as an effective treatment of ulcerative colitis in clinics. However, the active ingredients and the molecular mechanism have not been fully disclosed. It is imperative to explore the active ingredients and the mechanism of RSBDP. In this study, the potential active components for ulcerative colitis treatment in RSBDP were determined and predicted in silicon, and its molecular mechanisms were also presented, in which the PI3K/Akt/NF-κB signaling pathway was recognized to be vital. Basically, the pharmacodynamics and mechanistic studies of RSBDP for ulcerative colitis were implemented on TNBS-induced experimental rats. The results showed that RSBDP could ameliorate the disease activity index and colon weight, as well as improve colonic shortening and colon histology. In addition, the tumor necrosis factor-α (TNF-α), diamine oxidase, intercellular adhesion molecule-1, and endotoxin in serum were also reduced. It is worth mentioning that the PI3K/Akt/NF-κB signaling pathway was inhibited after RSBDP administration via inhibiting the phosphorylation of proteins. In conclusion, RSBDP effectively ameliorates TNBS-induced colitis rats by inhibiting the PI3K/Akt/NF-κB signaling pathway.
