Research progress on active ingredients of animal-derived traditional Chinese medicine in treatment of allergic rhinitis / 中国中药杂志

Allergic rhinitis(AR) is a common chronic inflammatory disease of the upper respiratory tract. Due to its high prevalence, high recurrence rate, and lack of a definitive cure, it is considered a global health issue by the World Health Organization. The pathogenesis of AR is complex and mainly involves B cells, helper T cells, eosinophils, basophils, macrophages, as well as the cytokines and inflammatory mediators they secrete. Clinical treatment primarily focuses on inhibiting inflammatory mediators such as histamine and leukotrienes. In recent years, active ingredients of animal-derived traditional Chinese medicine(TCM) have shown unique advantages and potential in AR treatment thanks to their high safety, specificity, selectivity, and biopotency. This study systematically reviewed the therapeutic effects and mechanisms of active ingredients and mixed extracts from animal-derived TCM, such as bovine spleen, honeycomb, bee venom, maggot, and human placenta, which have been shown by modern pharmacological research to regulate the immune function in AR, providing a reference for further exploration and clinical development of active ingredients from animal-derived TCM. Studies have found that the active ingredients from animal-derived TCM can produce definite therapeutic effects in AR by modulating multiple immune balances in the body, with great clinical prospects. However, their mechanisms of action still require further investigation, and the quality control techniques for effective ingredients need to be improved. Currently, the research on active ingredients from animal-derived TCM in China has adopted an interactive system consisting of "traditional medical experience-based research, bioinformatics and artificial intelligence predictions, and validation and development through new experimental techniques". Based on this system, animal-derived TCM can combine modern scientific and technological means to maximize the therapeutic effects of active ingredients and serve the clinical application of AR in a more efficient and innovative manner.

Anti-tumor and Phenotypic Regulation Effect of Matrine on Dendritic Cells through Regulating TLRs Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate the effects of matrine on antigen presentation of dendritic cells (DCs), and to explore the pharmacological mechanism of matrine on anti-tumor effect.@*METHODS@#Different concentrations (0, 1, 2, 4, 8 and 16 µ g/mL) of matrine were co-cultured with DCs, the harvested DCs were co-cultured with antigens of Lewis lung cancer (LLC) cells, and then DCs and T cells were co-cultured to produce DCs-activated killer (DAK) cells, which have significant tumor-killing activity. The expression of cytokines, mRNA and protein of toll-like receptors (TLRs) in DCs were detected by enzyme linked immunosobent assay, polymerase chain reaction and Western blot, respectively. And the killing effect of DAK were measured by MTT assay.@*RESULTS@#Matrine significantly increased the mRNA expression of TLR7, TLR8, myeloid differentiation factor 88 (MyD88), tumor necrosis factor receptor-associated factor 6 (TRAF-6) and I κ B kinase (IKK), as well as the protein expression of TLR7 and TLR8, and up-regulated the levels of interleukin-12 (IL-12), IL-6 and tumor necrosis factor-α (TNF-α), meanwhile, it also increased the expressions of MHC-II, CD54, CD80 and CD86 in DCs. DCs-activated effector T cells had significant tumor-killing activity. When the concentration of matrine was more than 4 µg/mL, all indices had significant difference (P<0.01 or P<0.05).@*CONCLUSION@#Matrine plays an anti-tumor role by regulating TLRs signal transduction pathway, promoting the secretion of inflammatory cytokines and enhancing immune function.

Pharmacodynamics and Mechanism of Chaijin Sanjie Prescription on Rats with Mammary Gland Hyperplasia / 中国实验方剂学杂志

Objective:To investigate the pharmacodynamics and mechanism of Chaijin Sanjie prescription (CJSJP) on rat mammary gland hyperplasia, in order to provide experimental basis for the research and development of new Chinese medicine. Method:SD rat model of mammary gland hyperplasia was established through exogenous intramuscular injection with estrogen and progesterone. After successful establishment of the model, the rats were randomly divided into normal group, model group, and low, medium and high-dose CJSJP groups (3.13, 6.26, 12.52 g·kg-1) and Rupixiao (0.517 g·kg-1) group, with 9 rats in each group. After 28 days of administration, estradiol (E2), progesterone (P) and rolactin (PRL) were measured by radioimmunoassay, uterus and ovary coefficients were calculated; nipple diameter and breast histopathology were observed, estrogen receptor-α(ER-α) expression in mammary gland was measured by immunohistochemistry, and gonadotropin-releasing hormone (GnRH) and gonadotropin-releasing hormone receptor (GnRH-R) mRNA expressions in hypothalamus, pituitary were measured by Real-time PCR. ICR mice were randomly divided into normal group, low, medium and high-dose CJSJP groups (5.2,10.4,20.8 g·kg-1) and Luotongding group (0.038 6 g·kg-1) according to their body weight. Twelve mice in each group were given drugs for 7 days, and 0.6% acetic acid was injected intraperitoneally for 30 minutes after the last administration. The writhing times were observed within 15 minutes. Result:Compared with the normal group, the diameter of nipple was widened, serum E2 was significantly increased (Pα expression were increased in model group. compared with model group, the diameter of nipple was significantly decreased in high dose group of CJSJP (P2 was decreased in all dose groups of CJSJP, pathological score of breast hyperplasia was decreased in middle and high dose groups of CJSJP, GnRH mRNA in hypothalamus was decreased in all dose groups of CJSJP. The writhing times of mice in high dose group of CJSJP was decreased (PConclusion:Chaijin Sanjie prescription can improve the lesions of breast hyperplasia. The therapeutic mechanism may be related to the regulation of GnRH gene expression in hypothalamus and the decrease of estrogen receptor expression.
