Tong Jing Yi Hao Formula Alleviates Ornidazole-Induced Oligoasthenospermia in Rats by Suppressing ROS/MAPK/HIF-1 Pathway

Background: Tong Jing Yi Hao Formula (TJYHF) is a Traditional Chinese medicine used for oligoasthenospermia (OAS) treatment. However, the role of TJYHF against OAS is unclear. This study was an initial attempt to solve this problem. Methods: Rats were randomly allocated to normal, ornidazole (Orn), levocarnitine (450 mg/kg), low-dose TJYHF (6.5 g/kg) and high-dose TJYHF (26 g/kg) groups, each consisting of six rats. Oral administration of Orn (400 mg/kg) for 4 weeks was used to induce OAS, followed by oral doses of the respective drugs for an additional 4 weeks. Parameters, including the testicular index, epididymis index, testicular volume, sperm parameters, sex hormone levels, histological changes and markers of oxidative stress, were evaluated to assess the effects of treatment. The potential mechanism involved in the therapeutic effects of TJYHF was studied by evaluating the activity and expression levels of key molecules within the reactive oxygen species (ROS)/mitogen-activated protein kinase (MAPK)/hypoxia-inducible factor 1 (HIF-1) pathway.Results: Compared with healthy rats, the Orn-induced rats demonstrated decreases in testicular index, epididymis index, testicular volume, sperm concentration, total sperm count, percentage of forwarding sperm motility, total sperm motility, testosterone, spermatogenic epithelium, reproductive cell, glutathione peroxidase, superoxide dismutase and glutathione and increases in sperm deoxyribonucleic acid fragmentation index, follicle-stimulating hormone, luteinizing hormone and malondialdehyde (AU)

Network pharmacology-based study of the protective mechanism of conciliatory anti-allergic decoction on asthma

BACKGROUND: This study aimed to explore the underlying anti-asthma pharmacological mechanisms of conciliatory anti-allergic decoction (CAD) with a network pharmacology approach. METHODS: Traditional Chinese medicine related databases were utilized to screen the active ingredients of CAD. Targets of CAD for asthma treatment were also identified based on related databases. The protein-protein interaction network, biological function and KEGG pathway enrichment analysis, and molecular docking of the targets were performed. Furthermore, an asthma mouse model experiment involving HE staining, AB-PAS staining, and ELISA was also performed to assess the anti-asthma effect of CAD. RESULTS: There were 77 active ingredients in CAD, including quercetin, kaempferol, stigmasterol, luteolin, cryptotanshinone, beta-sitosterol, acacetin, naringenin, baicalin, and 48 related targets for asthma treatment, mainly including TNF, IL4, IL5, IL10, IL13 and IFN-γ, were identified with ideal molecular docking binding scores by network pharmacology analysis. KEGG pathway analysis revealed that these targets were directly involved in the asthma pathway, Th1 and Th2 cell differentiation, and signaling pathways correlated with asthma (NF-κB, IL17, T cell receptor, TNF, JAK-STAT signaling pathways, etc.). Animal experiments also confirmed that CAD could attenuate inflammatory cell invasion, goblet cell hyperplasia and mucus secretion. The levels of the major targets TNF-Alpha, IL4, IL5, and IL13 can also be regulated by CAD in an asthma mouse model. CONCLUSION: The anti-asthma mechanism of CAD possibly stemmed from the active ingredients targeting asthma-related targets, which are involved in the asthma pathway and signaling pathways to exhibit therapeutic effects

Hangeshashinto (TJ-14) prevents radiation-induced mucositis by suppressing cyclooxygenase-2 expression and chemotaxis of inflammatory cells

Purpose. Radiation-induced oral mucositis is the most common side effect of radiotherapy in head and neck cancer; however, effective modalities for its prevention have not been established. In this study, we evaluated the effectiveness of Hangeshashinto (TJ-14), a Japanese herbal medicine, for preventing radiation-induced mucositis and elucidated its effect on inflammatory responses, including inflammatory cell chemotaxis and cyclooxygenase-2 (COX2) expression, in an animal model. Methods. Syrian hamsters, 8–9 weeks old, were enrolled in this study. Animals were irradiated with a single 40 Gy dose to the buccal mucosa. Hamsters freely received a treatment diet mixed with 2% TJ-14 or a normal diet daily. The therapeutic effect was determined based on the visual mucositis score, body weight, and histological examination of infiltrated neutrophils and COX2 expression. Results. TJ-14 significantly reduced the severity of mucositis. The percentage with severe mucositis (score ≥3) was 100% in the untreated group and 16.7% in the TJ-14 group (P < 0.05). There was no difference in body weight change between the groups; however, weight gain in the untreated group tended to be suppressed compared to that in the TJ-14 group during the peak period of mucositis. In addition, TJ-14 inhibited the infiltration of neutrophils and COX2 expression in irradiated mucosa (P < 0.05). Conclusions. TJ-14 reduced the severity of mucositis in an animal model by suppressing the inflammatory response. Because TJ-14 is inexpensive and its safety is established, it is a promising candidate for the standard treatment of radiation-induced mucositis in cancer patients (AU)

Métodos: En el experimento de este trabajo, se establecen los espectros de identificación de Chishao en todas las localizaciones mediante RP-HPLC y el método del análisis de componentes principales con las áreas pico de RPHPLC. Resultados: La calidad de Chishao en el norte de China o del procedente de Paeonia lactiflora es mejor que la de otras localizaciones o procedente de P. obovata, P. mairei y P. anomala. Los resultados son congruentes con la impresión tradicional de la calidad de esta planta. Estos resultados indican que el análisis de los componentes principales (ACP) puede utilizarse como método eficaz y económico para evaluar la calidad de Chishao y podría aplicarse a otras plantas medicinales chinas. Conclusiones: Dada la complicada base de la eficacia de la Medicina tradicional china (MTC), un método como el ACP para diversos componentes químicos parece ser más adecuado para la evaluación de la calidad de la MTC en comparación con la determinación de un único o unos pocos agentes químicos (AU)

La levadura roja de arroz en el tratamiento de la hipercolesterolemia / Red yeast rice in the treatment of hypercholesterolemia

Las estatinas se han convertido en el medicamento esencial en la prevención y en el tratamiento de la enfermedad coronaria. Sin embargo, alrededor del 20%de los pacientes tratados desarrollan mialgias u otros efectos adversos de tipo muscular. Afortunadamente, existen otras substancias hipolipemiantes alternativas como la levadura roja de arroz y la suplementación con vitamina D y coenzima Q10 (AU)

Statins have become the essential medicine in the prevention and treatment of coronary heart disease. However, around 20% of the treated patients develop myalgias or other adverse effects of muscular type. Fortunately, there are other alternative lipid substances such as red yeast rice and supplementation with vitamin D and coenzyme Q10 (AU)

The effects of Weichangshu tablet on intracellular Ca2+ concentration in cultured rat gastrointestinal smooth muscle cells

No disponible

The objective of this study was to explore the effects of Weichangshu tablets on free Ca2+concentration of the gastrointestinal smooth muscle cells of rats and the molecular mechanism of the Weichangshu tablets. Cultured SD rat gastrointestinal smooth muscle cells were divided into control group, Cisapride group, Weichangshu group, and control + ethylene glycol tetraacetic acid (EGTA) group, Cisapride + EGTA group, and Weichangshu + EGTA group. Laser scanning microscope and spectrophotometer detection were applied to detect the calcium concentration. The calcium concentrations in Weichangshu group and Cisapride group significantly increased vs. control, and those in Weichangshu group were higher than those in Cisapride group. Ca2+concentration in Weichangshu + EGTA group, Cisapride + EGTA group vs. control + EGTA group were not significantly different. Weichangshu could increase gastrointestinal smooth muscle free Ca2+ concentration, and this role may be achieved through the promotion of cells within the flow of calcium ions (AU)
