Background. The Caoguo-4 decoction, a classical Mongolian medicine formula, is widely used to treat spleen deficiency diarrhea (SDD) in Mongolian for decades. Previously, the Caoguo-4 decoction volatile oil has been confirmed to be effective in ameliorating symptoms of spleen deficiency diarrhea in an animal model. However, the underlying mechanism of the Caoguo-4 decoction volatile oil is yet to be established. The aim of the current study was to investigate the antidiarrheal effects and mechanism of the Caoguo-4 decoction volatile oil. Method. Wistar rats were randomly divided into 5 groups of 10 animals including control, model, positive, Caoguo-4 decoction, and Caoguo-4 decoction volatile oil groups (10 rats in each group). All the rats, besides those in the control group, were induced to develop SDD by a bitter-cold purgation method with Xiaochengqi decoction. The antidiarrheal effect of Caoguo-4 decoction volatile oil was evaluated by pathological section, serum D-xylose and AMS content, plasma MTL content, and gut microbiota analysis via 16S rRNA sequencing. Results. The results showed that the developed SDD rat model (model group) had decreased food intake, increased weight loss, soft stool, and bad hair color. When compared with the control group, serum was significantly reduced serum D-xylose and AML but increased MTL levels in the model group ( p < 0.05 ). However, after treatment with either the Caoguo-4 decoction (the decoction group) or Smecta (the positive group) or volatile oil from the Caoguo-4 decoction (the volatile oil group), a significant increase in the serum D-xylose levels was observed. Additionally, AML levels significantly increased in the positive and volatile oil groups, and MTL levels significantly decreased in the decoction and volatile oil groups, when compared with the model group ( p < 0.05 ). The pathological changes of the intestinal mucosa showed that the structure of the epithelium in the villi of the small intestine was affected, deformed, and incomplete in the model group when compared with the control group. However, either the decoction group or the volatile oil group recovered the villous morphology. The results of OTU analysis and alpha diversity analysis of intestinal bacteria showed that the intestinal microbiota of the SDD model rats showed an obvious decrease in richness and diversity of intestinal microbiota. But the intervention treatment of decoction and volatile oil could significantly recover the richness and diversity of intestinal microbiota. Conclusion. The intestinal microbiota destroyed in SDD modelling could be significantly improved by the Caoguo-4 decoction volatile oils, which provides reference for clinical medication.
Purpose. To explore the clinical application of Baihe Dihuang Decoction. To provide certain data support and theoretical basis for the clinical application of Baihe Dihuang Decoction in the future. Methods. With “Baihe Rehmannia Tang” as the search term, the search was carried out on CNKI, VIP, Wanfang, PubMed and other databases. The statistical analysis of Baihe Dihuang decoction for treating diseases was obtained. Meta-analysis of the data was performed using RevMan 5.3 software to analyze the main therapeutic indicators of the disease. Results. According to the 83 valid literature that can be found, it is shown that 17 are used for the treatment of depression, 14 are used for the treatment of menopausal syndrome, 24 are used for the treatment of insomnia, and 28 are used for the treatment of other diseases. Conclusion. In the treatment of depression, menopausal syndrome, and insomnia combined with Baihe Dihuang Decoction can have a better therapeutic effect and diminish the incidence of adverse reactions. It provides a theoretical basis for the study and experimental study of its active components.
Background and objective: Myocardial Infarction (MI) is a cardiovascular disease with a high morbidity and mortality rate. While MI is currently treated with pharmaceuticals, there is a need for new treatment options: compound Chinese medicines may have unique advantages for the treatment of MI. In this study, we used network pharmacology to explore the molecular mechanisms of action of Chinese Longmai Ning decoction (CLMN) as a potential treatment approach.Methods: Chip data related to Myocardial Infarction were downloaded from the GEO database and genes from GSE48060 and GSE66360 chips were obtained by R language. The targets of active components of compound CLMN and myocardial infarction disease were predicted by network pharmacology. After intersection analysis, the core targets were obtained and functional enrichment analysis was carried out. CLMN biological activity was verified by molecular docking prior to establishing a mouse MI model to verify efficacy using hematoxylin-eosin staining (HE) and immunohistochemistry.Results: KEGG pathway analysis showed that TNF, IL1B, PTGS2, VCAM1, and NFKBIA which mainly act on NF-kappa B pathway contribute to the anti-inflammatory effects of CLMN. Immunohistochemical analysis showed that TNF-α and TRAF-2 expression levels in MI of CLMN-treated mice were decreased, while IkBα was increased (P < 0.05). HE staining showed CLMN reduced inflammation in mouse cardiomyocytes and decreased fibrosis.Conclusion: CLMN regulates the NF-kappa B signaling pathway and the expression of TNF, IL1B, PTGS2, VCAM1 and NFKBIA. Chemical analysis showed that CLMN active components such as Daidzein-4,7-diglucoside, rutin and puerarin may be responsible for the therapeutic effect of the decoction.
