ABSTRACT

ObjectiveTo mine the compatibility rules of patented traditional Chinese medicine (TCM) compound prescriptions for treating chronic atrophic gastritis (CAG) by systems pharmacology and molecular docking methods, and predict the targets and molecular mechanisms of Chinese medicinals with different efficacy in the treatment of CAG. MethodThe TCM compound prescriptions for treating CAG were extracted from the patent system of the China National Intellectual Property Administration. The active components and targets of the prescriptions were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Traditional Chinese Medicine Integrative Database (TCMID), and UniProt. The candidate targets and pathways of CAG were obtained from GeneCards, DisGeNet, Online Mendelian Inheritance in Man (OMIM), MalaCards, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome. The gene ontology (GO) functional annotation and KEGG pathway enrichment were realized by R Studio 4.1.2. STRING11.0 was employed to build the protein-protein interaction (PPI) network, and AutoDock Vina 4.2.6 was used for the docking between key targets and components. ResultA total of 228 TCM compound prescriptions for treating CAG were extracted. The medicinals used in these prescriptions mainly had warm or cold nature, bitter or sweet taste, tropism to the spleen, stomach, and liver meridians, and the efficacy of tonifying Qi, regulating Qi movement, clearing heat, and activating and toniying blood. The prescriptions mainly treated CAG via p53, mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), forkhead box protein O (FoxO), vascular endothelial growth factor (VEGF), and hypoxia-inducible factor-1 (HIF-1) signaling pathways. Molecular docking results confirmed that the active components in the prescriptions had docking activities with key receptor proteins. ConclusionThis study preliminarily analyzed the compatibility rules of TCM compound prescriptions in the treatment of CAG. The medicinals with different efficacy treat CAG by regulating cell proliferation, apoptosis, and oxidative stress response, preventing carcinogen production, promoting gastric acid secretion, and improving local microcirculation in a multi-target, multi-pathway, multi-link manner. The findings facilitate the research on the TCM treatment of CAG.

ABSTRACT

Diabetic kidney disease is an important microvascular complication of diabetes and the leading cause of end-stage renal disease. Its pathological characteristics mainly include epithelial mesenchymal transition(EMT) in glomerulus, podocyte apoptosis and autophagy, and damage of glomerular filtration barrier. Transforming growth factor-β(TGF-β)/Smad signaling pathway is specifically regulated by a variety of mechanisms, and is a classic pathway involved in physiological activities such as apoptosis, proliferation and differentiation. At present, many studies have found that TGF-β/Smad signaling pathway plays a key role in the pathogenesis of diabetic kidney disease. Traditional Chinese medicine has significant advantages in the treatment of diabetic kidney disease for its multi-component, multi-target and multi-pathway characteristics, and some traditional Chinese medicine extracts, traditional Chinese medicines and traditional Chinese medicine compound prescription improve the renal injury of diabetic kidney disease by regulating TGF-β/Smad signaling pathway. This study clarified the mechanism of TGF-β/Smad signaling pathway in diabetic kidney disease by expounding the relationship between the key targets of the pathway and diabetic kidney disease, and summarized the research progress of traditional Chinese medicine in the treatment of diabetic kidney disease by interfering with TGF-β/Smad signaling pathway in recent years, to provide reference for drug research and clinical treatment of diabetic kidney disease in the future.

ABSTRACT

ObjectiveTo observe the protective effect of Baoshen prescription against renal fibrosis and explore its underlying mechanism through network pharmacology, molecular docking, and in vivo experiments. MethodAll mice were randomly divided into sham surgery group, model group, low-, medium-, and high-dose Baoshen prescription groups, and a benazepril hydrochloride group. Unilateral ureteral obstruction (UUO) was performed to establish a renal fibrosis model, and the administration of Baoshen prescription at low, medium, and high doses (0.455, 0.91, and 1.82 g·kg-1), and benazepril hydrochloride (1.68 mg·kg-1) or distilled water began on the same day as model preparation. Mice in the model group and the sham surgery group were given an equal volume of distilled water. The intervention was carried out once daily for 14 days. Mouse serum levels of blood urea nitrogen (BUN) and creatinine (Cr) were measured. Hematoxylin-eosin (HE) staining and Masson staining were used to observe renal pathological changes. Western blot and immunohistochemistry were used to assess the expression of fibronectin (FN), α-smooth muscle actin (α-SMA), and E-cadherin, which are related to renal fibrosis. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to measure the mRNA expression of transforming growth factor-β1 (TGF-β1), tumor necrosis factor-α (TNF-α), NOD-like receptor protein 3 (NLRP3), and monocyte chemoattractant protein-1 (MCP-1) in renal tissues. The mechanism of Baoshen prescription in improving renal fibrosis was explored through network pharmacology, molecular docking, and Western blot experiments. ResultCompared with the sham surgery group, the model group showed significantly increased levels of BUN and Cr (P<0.01). The model group exhibited abnormal renal glomerular morphology, loss of tubular brush borders, tubular dilation, and an enlarged area of blue collagen fibers. Mice in the model group showed significantly elevated levels of FN and α-SMA (P<0.01), significantly decreased expression of E-cadherin (P<0.01), and significantly increased expression of TGF-β1, TNF-α, NLRP3, and MCP-1 mRNA (P<0.05, P<0.01). Compared with the model group, the Baoshen prescription groups showed significantly reduced BUN and Cr levels (P<0.01), alleviated renal pathological damage, improved fibrosis, reduced expression of FN and α-SMA (P<0.01), increased E-cadherin expression (P<0.01), and downregulated mRNA expression of TGF-β1, TNF-α, NLRP3, and MCP-1 (P<0.05, P<0.01). Network pharmacology and molecular docking predicted that Baoshen prescription could potentially improve renal fibrosis through the extracellular signal-regulated kinase (ERK)/p38 mitogen-activated protein kinase (MAPK) signaling pathway. Pharmacological research showed that compared with the sham surgery group, the model group exhibited significantly increased expression of phosphorylated (p)-ERK and p-p38 (P<0.05, P<0.01). Compared with the model group, medium- and high-dose Baoshen prescription groups showed significantly downregulated expression of p-ERK and p-p38 proteins (P<0.05, P<0.01). ConclusionBaoshen prescription can effectively improve renal fibrosis induced by UUO in mice, and its mechanism of action may be related to the ERK/p38 MAPK signaling pathway.

ABSTRACT

Cholagogic traditional Chinese medicines refer to those that can promote bile secretion and excretion, strengthen gallbladder contraction and promote gallbladder emptying. They are mainly used to treat cholecystitis, gallstones, cholestasis, biliary tract infection, jaundice hepatitis and other diseases in clinical application. As a traditional medicine in our country, Chinese herbal medicines have many advantages, such as extensive resources, low cost, little or no toxic and side effects, and in addition, it is not easy for animals to produce drug resistance. With the progress of science and technology and the rapid development of traditional Chinese medicine, many achievements have been made in the research of cholagogic traditional Chinese medicines. Traditional Chinese medicine plays a cholagogic role mainly by promoting bile secretion, regulating SCP2 mRNA, FXR, BSEP and efflux transporter protein, dissolving cholesterol, promoting the relaxation of Oddi's sphincter and changing the composition of bile, etc. Traditional Chinese medicine decoction, traditional Chinese medicine preparation, Chinese medicine combined with acupuncture, ear acupoint pressing, soaking bath, western medicine and alike are often used to treat biliary system diseases in clinical practice. The effective rate of combination of traditional Chinese medicine and other methods was significantly higher than that of compound prescription, western medicine, acupuncture and soaking bath alone. General attack therapy and new therapies are also used in clinical treatment. The clinical effect of traditional Chinese medicine is remarkable. By means of literature review, the pharmacological effects, mechanism and clinical application of Chinese herbal medicines and compound prescriptions with gallbladder-promoting effect in the past 15 years were summarized in this paper. At the same time, some existing problems were found and prospects were expected.

ABSTRACT

Aim To study the pharmacodynamics of antianxietic compound prescription capsule ( ACPC ) on acute stress in rats and the influence upon the ex-pression of ERK/CREB signal pathway and brain-de-rived neurotrophic factor ( BDNF) in the cerebral cor-tex and hippocampus of rats. Methods The elevated plus maze ( EPM ) test was applied to observe the effects of ACPC on acute stress rats administered 7 d low-, medium- and high-dose ( 0. 75 , 1. 5 , 3 g · kg-1 ) . The expression of ERK/CREB signal pathway and BDNF in the cerebral cortex and hippocampus of rats were studied by using Western blot method. Re-sults In EPM, high-dose of ACPC increased signifi-cantly the rat open arm time ( OT%) ( P<0 . 05 ) and the percentage of open arm entries ( OE%) ( P <0. 05). In Western blot, the medium-dose of ACPC reduced significantly p-ERK1/2 expression in hippo-campus ( P <0. 05 ) , and high-dose group decreased significantly the expression of p-ERK1/2 and p-CREB in the cortex and hippocampus of rats ( P <0. 05 ) . High-dose group increased significantly the expression of BDNF in the cortex and hippocampus of rats ( P<0. 05 , P<0. 01 ) . Conclusion ACPC has anti-anxie-ty effect in the model of EPM, and its mechanism may be related to the ERK/CREB signal pathway and in-creased BDNF expression.
