[Mechanism of heat-clearing prescriptions in alleviating type 2 diabetes mellitus:a review].

Type 2 diabetes mellitus(T2DM), a common chronic metabolic disease, is often accompanied by internal heat syndrome. Heat-clearing prescriptions are widely used to treat different heat syndromes of T2DM from the aspects of clearing stagnant heat, excess heat, damp heat, phlegm heat, and heat toxin, demonstrating remarkable effects. The mechanism of blood sugar-lowering agents has always been a hotspot of research. Recently, the basic studies of heat-clearing prescriptions from different perspectives have been increasing year by year. To clarify the mechanisms of heat-clearing prescriptions and find specific mechanisms, we systematically reviewed the basic studies of heat-clearing prescriptions commonly used for the treatment of T2DM in the past decade, intending to provide a reference for related research.

RNA-sequencing Reveals Differentially Expressed Genes of Laying Hens Fed Baihu Decoction Under Heat Shock.

Egg production, an important economic trait in the poultry industry, is sensitive to heat stress. The hypothalamus is a crucial center for thermoregulation by detecting temperature changes and regulating the autonomic nervous system in poultry. Baihu decoction (BH), which contains four ingredients (Rhizoma Anemarrhenae, Gypsum Fibrosum, Radix Glycyrrhizae, and Semen Oryzae Nonglutinosae), is a traditional Chinese medicinal formula for clearing heat. Our study aimed to investigate the changes in gene transcription levels in the hypothalamus of laying hens treated with heat stress with and without BH using RNA sequencing. A total of 223 differentially expressed genes (DEGs) were identified in the heat-treated group compared with the control group and 613 DEGs were identified in the BH group compared with the heat-treated group. Heat shock led to significant changes in the expression of multiple genes involved in the "neuroactive ligand-receptor interaction" pathway. Moreover, feeding BH led to significant upregulation in the expression of eight genes encoding heat shock proteins (HSPs), which were highlighted as candidates to control the "protein processing in the endoplasmic reticulum (ER)" pathway. These results provide the novel insight that BH responds to heat stress by participating in regulation of the ER signaling pathway and HSPs expression.

Modified Baihu decoction therapeutically remodels gut microbiota to inhibit acute gouty arthritis.

Background: Acute gouty arthritis (AGA) is the most common first symptom of gout, and the development of gout as a metabolic and immune inflammatory disease is also correlated with the gut microbiota. However, the mechanism of the effect of changes in the gut microbiota on AGA remains unclear. The intestinal flora can not only affect purine metabolism or regulate inflammation, but also influence the therapeutic effect of drugs on AGA. The aim of this study was to investigate the exact mechanism of modified Baihu decoction (MBD) in the treatment of AGA and whether it is related to the regulation of the structure of the intestinal flora. Methods: On the 21st day of MBD administration by continuous gavage, a rat acute gouty arthritis model was constructed using sodium urate (0.1 mL/rat, 50 mg/mL), and the ankle joint swelling was measured before and 4 h, 8 h, 24 h, and 48 h after the injection of sodium urate. After 48 h of sodium urate injection, serum, liver, kidney, ankle synovial tissue and feces were collected from rats. The collected samples were examined and analyzed using H&E, Elisa, Immunohistochemistry, Histopathology, 16S rDNA, and Biochemical analysis. To investigate the mechanism of MBD to alleviate AGA using pro-inflammatory factors and intestinal flora. Results: MBD (5.84, 35 g/kg) was administered orally to AGA rats and diclofenac sodium tablets (DS-tablets) were used as standard treatment control. Serum biochemical assessment confirmed that MBD is a safe drug for the treatment of AGA. In addition, our findings confirmed that MBD relieved AGA-related symptoms, such as toe swelling. Lowering serum levels of uric acid, IL-1ß, and TGF-ß1 immunohistochemical results also confirmed that MBD reduced the expression of inflammatory elements such as IL-1ß, NLRP3, ASC, and Caspase-1 in synovial tissue.Furthermore, compared with control group, the 16s rDNA sequencing of AGA rat faeces revealed an increase in the relative abundance of Lachnospiraceae, Muribaculaceae, and Bifidobacteriaceae species. While the relative abundance of Lactobacillaceae, Erysipelotrichaceae, Ruminococcaceae, Prevotellaceae and Enterobacteriaceae showed a relative decrease in species abundance. Of these, the reduction in species abundance of Enterobacteriaceae was associated with a reduction in amino acid metabolism and environmental perception. After MBD therapeutic intervention, the disturbance of the intestinal flora caused by AGA was restored. Conclusion: In summary, MBD is an effective agent for the treatment of AGA, with the potential mechanism being the regulation of intestinal flora to control inflammation. This would help to promote the therapeutic effect of MBD on AGA.

[Quality characterization analysis of single decoction and merger decoction of Baihu and Guizhi].

To study the differences and similarities in pharmaceutical characterization and pharmacodynamic characterization between the single decoction and merger decoction of Baihu and Guizhi. The same technology parameters were used to prepare Baihu and Guizhi single decoticon and merger decoction extracts, and then the differences and similarities in pharmaceutical characterization were analyzed based on their HPLC fingerprint, content of index components, and the extraction content. The pharmacodynamic differences and similarities were analyzed by inflammatory model and pain model. There was no significant difference in HPLC chromatographic peak, but the peak area value reflected the difference of quantity to some extent. It was found that the peak value of single Rhizoma anemarrhenae and Cassia twig decoction was less than the peak of their merger decoction, but the peak value of single honey-fried Licorice root decoction was greater than the peak of merger decoction． The contents of neomangiferin, mangiferin and timosaponin B Ⅱ among index components as well as extraction content in merger decoction were higher than those in single decoction． The contents of liquiritin and glycyrrhizic acid as well as extraction content in merger decoction were lower than those in single decoction． There was no significant difference in the content of cinnamicacid and its extraction content between merger decoction and single decoction. According to the efficacy experiment, both of them showed significant anti-inflammatory and analgesic effects. However, the merger decoction showed faster anti-inflammation effect, and longer analgesic effect. It can be concluded that the merger decoction and single decoction of Baihu and Guizhi have the same material basis, and the merger decoction is better for the dissolution of the active ingredients in this recipe, and is more beneficial to the therapeutic effect.

Immunological mechanism of Panax ginseng for promoting antipyretic effects of Baihu Decoction by network pharmacology / 中草药

Qi-fen fever is a syndrome of Qi-fen syndrome in defensive qi nutrient blood syndrome differentiation. Baihu Decoction is a classic prescription of cooling Qi-fen, but when yang brightness heat at qi aspect is too exuberance to hurt human healthy qi and body fluid, Baihu with Ginseng Decoction will be used for treatment. In order to explore the mechanism of antipyretic effects of Baihu with Ginseng Decoction, this paper applied the network pharmacology method on the basis of summarizing the effects of ginseng on the natural immune system and the relationship between fever and the natural immune system. Firstly, 22 chemically active components of ginseng and their corresponding targets were screened by TCMSP database under limited conditions, and HPO database was used to search for fever-related disease targets. Secondly, the "ginseng-target-fever" network was constructed by STRING database corresponding to ginseng chemical active ingredients target and fever-related disease targets, and Cytoscape software was used to visualize the above network and obtained 18 key nodes according to the relevant characteristic parameters. Finally, The GATHER database platform was applied for the enrichment analysis of the gene function of key nodes. According to the network construction and topological calculation, it suggests that ginseng could activate the natural immune system by regulating MyD88-dependent or MyD88-independent Toll-like receptor signaling pathway to promote the antipyretic effects of Baihu Decoction.
