RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: Tianma-Gouteng granules (TGG) is a traditional Chinese medicine (TCM) compound that was first recorded by modern medical practitioner Hu Guangci in "New Meaning of the Treatment of Miscellaneous Diseases in Traditional Chinese Medicine". It is widely used to treat hypertensive vertigo, headache and insomnia. AIM OF STUDY: To investigate the antihypertensive effect of TGG and explore its mechanism. MATERIALS AND METHODS: Spontaneously hypertensive rats (SHR) were prepared a model of the ascendant hyperactivity of liver yang syndrome (AHLYS), blood pressure and general state of rats were recorded. A series of experiments were performed by enzyme-linked immunosorbent assay (ELISA), ultra high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS), 16S rRNA sequencing, real-time fluorescence quantitative PCR (RT-qPCR), and enzymatic colorimetry. RESULTS: TGG can effectively lower blood pressure and improve related symptoms. TGG significantly reduced the levels of IL-1ß, IL-6, TNF-α, Renin and AngII. A total of 17 differential metabolites were found in plasma, with the two most potent metabolic pathways being glycerophospholipid metabolism and primary bile acid biosynthesis. After TGG intervention, 7 metabolite levels decreased and 10 metabolite levels increased. TGG significantly increased the relative abundance of Desulfovibio, Lachnoclostridium, Turicibacter, and decreased the relative abundance of Alluobaculum and Monoglobu. TGG also downregulated Farnesoid X Receptor (FXR) and Fibroblast Growth Factor 15 (FGF15) levels in the liver and ileum, upregulated Cholesterol 7α-hydroxylase (CYP7A1) levels, and regulated total bile acid (TBA) levels. CONCLUSION: TGG can regulate bile acid metabolism through liver-gut axis, interfere with related intestinal flora and plasma metabolites, decrease blood pressure, and positively influence the pathologic process of SHR with AHLYS. When translating animal microbiota findings to humans, validation studies are essential to confirm reliability and applicability, particularly through empirical human research.

BACKGROUND: Peptic ulcer (PU) is a common clinical disease of the digestive system, which can occur in all ages, gastric and duodenal ulcers are the most commonly seen PUs in clinical practice. The main manifestations are chronic and periodic rhythmic upper abdominal pain, accompanied by indigestion symptoms such as pantothenic acid, belching, and nausea. Serious complications such as bleeding, perforation, obstruction and canceration are easy to occur, endangering the life safety of patients. There are many ways to treat PU in clinic, and acupoint catgut embedding therapy has its unique advantages. Hence, our systematic review aims to evaluate the efficacy and safety of acupoint embedding therapy in the treatment of PU and to provide a reliable basis for physician. METHODS: We will search electronic databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database (WF), China Biomedical Literature Database (CBM), and China Scientific Journals Database (VIP) from establishment to April 2021, and will manually searched the list of medical journals as a supplement. Two authors will screen the studies independently, as well as extract data information, and assess methodological quality through the Cochrane risk of bias (ROB) tool. The Stata software (Version 16.0) software will be used for statistical analysis. RESULTS: By evaluating the current status of acupoint catgut embedding for Peptic ulcer disease, this study would prove the effectiveness and safety of acupoint embedding therapy, and will be published in a peer-reviewed journal. CONCLUSION: This systematic review will provide a credible evidence-based for acupoint catgut embedding in the treatment of peptic ulcer. INPLASY REGISTRATION NUMBER: INPLASY202130097.
