Effect of Fuzheng Kangai Decoction on Immune Regulation and Inhibition of Tumor Growth in Rats with Ovarian Carcinoma / 中国实验方剂学杂志

Objective:To explore the effect of Fuzheng Kangai decotion （FZKAD） on the immune regulation and the inhibition of tumor growth in rats with ovarian carcinoma. Method:Kunming mice were randomly divided into normal group， lentinan （0.05 g·kg^-1） group， and high （27.3 g·kg^-1）， medium （13.65 g·kg^-1） and low （6.825 g·kg^-1） dose groups of FZKAD， with 10 mice in each group， serum hemolytic value （HC₅₀）， antibody-forming cells and the phagocytosis of mononuclear macrophages were measured. Fischer 344 rat xenograft model was established through inoculation of NUTU-19 cell in the right axilla， and the model rats were randomly divided into model group， cisplatin group （0.002 g·kg^-1）， and high （18.9 g·kg^-1）， medium （9.45 g·kg^-1）， and low （4.725 g·kg^-1） dose groups of FZKAD， with 10 rats in each group， in addition， 10 healthy rats were randomly selected as the normal group. Tumor quality， tumor inhibition rate， T lymphocyte subsets， and expressions of serum cytokines， enhancer binding protein homologous protein 1（XBP1） and enhancer binding protein homologous protein （CHOP） protein in tumor tissues were detected after 14 days of administration. Result:Compared with normal group， HC₅₀， level of antibody-forming cells， phagocytic index and phagocytic activity of mice in high， medium and low-dose groups of FZKAD were significantly increased （<italic>P</italic><0.05， <italic>P</italic><0.01）. Tumor quality and XBP1 protein expression in high， medium and low-dose groups of FZKAD were significantly decreased （<italic>P</italic><0.01） compared with the model group， while the tumor inhibition rate， CD4⁺， CD8⁺ T cell ratio， CD4⁺/CD8⁺ ratio， tumor necrosis factor-<italic>α</italic> （TNF-<italic>α</italic>）， interleukin-2 （IL-2）， <italic>γ-</italic>interferon （IFN-<italic>γ</italic>） expression and CHOP protein expression were significantly increased （<italic>P</italic><0.05， <italic>P</italic><0.01）. Conclusion:FZKAD can improve the immune function of normal mice and inhibit the tumor growth in rats with ovarian carcinoma， and the immunity regulation effect is the main mechanism.

Mechanism of Chinese Medicine Against Sjögren Syndrome： A Review / 中国实验方剂学杂志

Sjögren syndrome （SS） is a chronic autoimmune disease characterized by immune cell infiltration and progressive destruction of salivary and lacrimal glands. It not only affects the lacrimal and salivary glands， manifested as dry eyes and dry mouth， but also involves heart， lung，kidney，and central nervous system， seriously affecting human physical and mental health. Although western medicine has made extensive and in-depth research on the diagnosis and treatment of this disease in recent years，there is no effective treatment targeting the potential causes. Chinese medicine emphasizes the concept of holism，treatment and prescription formulation based on syndrome differentiation， and effect exertion via multiple targets，multiple levels，and multiple pathways，exhibiting great advantages in the treatment of SS. This paper reviews the mechanisms of Chinese medicine in treating SS from the perspectives of immunity regulation，aquaporin up-regulation， and anti-oxidative stress reported in the related literature，so as to provide more theoretical basis for the research and clinical treatment of SS.

New progress in pharmacological action of paeoniflorin / 中草药

Paeoniflorin is the main effective component of Paeoniae lactiflora and Paeonia suffruticosa. A large number of studies have proven that paeoniflorin has many pharmacological effects, such as anti-depression, anti-inflammation, analgesia, anti-tumor, liver protection, nerve protection, sedation and hypnosis, immunomodulation and so on. It has little toxic and side effects and has been highly concerned by people. At present, paeoniflorin is rarely used in clinical practice in the form of monomers. This article mainly refers to the related research literatures on paeoniflorin pharmacological action in recent three years, combs and summarizes the new progress of its pharmacological action research. The relationship between the drug effect and the prescription of traditional Chinese medicine was discussed, in order to provide a reference for further development and clinical application of paeoniflorin.

Research progress on anti-aging pharmacological effects and mechanisms of plant essential oil / 中草药

Plant essential oil not only has functions of anti-oxidative and scavenging free radicals activities, piliation promotion, osteoporosis prevention, body immunity regulation and other anti-physiological aging effects, but also has anti-pathogenic aging effects such as regulating neurodegenerative diseases, cardiovascular and cerebrovascular diseases, osteoarthritis and cancer. This paper introduces the research and progress of the pharmacological effects and mechanisms of anti-aging effects of plant essential oils by introducing the concept and mechanism of aging, and discusses the application prospects, development advantages and existing problems of plant essential oils in the anti-aging field.

Anti-tumor Effect of Astragaloside by Inducing M1 Macrophage Polarization / 中国实验方剂学杂志

Objective:To investigate the effect of astragaloside on the macrophage polarization and the possible anti-tumor immunity mechanism of astragaloside. Method:The cytotoxic effect of different concentrations of astragaloside at different time points on macrophage was measured by methylthiazolyldiphenyl-tetrazolium bromide (MTT), in order to choose the suitable concentration of astragaloside, macrophages were co-cultured with tumor cells at the ratio 1:1, and the effect of astragaloside on macrophage-mediated lysis of tumor cells was performed by biophotonic cytotoxicity assay after the mixed cells were effected with 0.1 mg·L-1 astragaloside for 24 h. Macrophages were dealt with 0.1 mg·L-1 astragaloside for 24h, the expressions of CD16/32 and CD206 in macrophages were performed by flow cytometry, the mRNA expressions of macrophage inducible nitric oxide synthase (iNOS), Arginine-1 (Arg-1), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-12 (IL-12), interleukin-10 (IL-10) and transforming growth factor-β (TGF-β) were measured by Real-time PCR, the protein expressions of macrophage signal transducers and activators of transcription 1 (STAT1) and phosphorylation signal transducers and activators of transcription 1 (p-STAT1) were determined by Western blot. Result:Astragaloside had no effect on the viability of macrophages with 0.1 mg·L-1. Compared with control group, astragaloside obviously enhanced the macrophage-mediated lysis of tumor cells according to the biophotonic cytotoxicity assay, induced the M1 macrophage marker CD16/32 expression according to flow cytometry, increased the mRNA expressions of iNOS, IL-1β, TNF-α and IL-12 according to the Real-time PCR, and promoted the phosphorylation of STAT1 in macrophages on the basis of Western blot. Conclusion:Astragaloside could induce M1 macrophage polarization by increasing the phosphorylation of STAT1, and initiate macrophage-related anti-tumor immunity response.

Advances in pharmacological research on Dendrobii Caulis based on strengthening enterogastric function / 中草药

Dendrobii Caulis was traditionally used for promoting middle energizer, strengthening enterogastric function to light body weight, and prolonging life according to Shennong's Classic of Materia Medica and many other previous ancient books of traditional Chinese medicine. The stomach and intestine tonic effect is still approved in modern society and broadly applied in clinic, whose efficacy has been featured as replenishing yin for maintaining gastric tonicity, enhancing the production of body fluid, and clearing away heat in Chinese Pharmacopoeia 2015. This review firstly made a summary of ancient literature on strengthening enterogastric function of Dendrobii Caulis, combined with literature of modern pharmacological research and clinical application from literature search system, such as CNKI, etc. It was summarized that Dendrobii Caulis had broad bioactivities in enterogastric system including gastric mucosa protection, digest-promotion, intestinal flora modulation, intestinal immunity regulation, stimulation of digestive juice secretion, etc. Furthermore, present situation of product development was analyzed based on patent and health product search system. This review could provide a reference for further development and clinical application of Dendrobii Caulis.
