Research progress of effect of Rhei Radix et Rhizoma and its anthraquinone in treatment of autoimmune diseases / 中国中药杂志

Rhei Radix et Rhizoma was first recorded in Shennong Ben Cao Jing, with a wide range of pharmacological activities. Autoimmune disease is a kind of disease that damages the tissue structure and function of immune cells and their components due to the impairment of immune tolerance function, including atherosclerosis, multiple sclerosis, gout, rheumatoid arthritis, autoimmune thyroiditis, ulcerative colitis, type 1 diabetes and IgA nephropathy. In recent years, clinical and experimental studies show that Rhei Radix et Rhizoma has potential therapeutic effects on autoimmune diseases. Under the guidance of the theory of traditional Chinese medicine, this paper reviews therapeutic and intervening effects of Rhei Radix et Rhizoma and its main active ingredient anthraquinone on autoimmune diseases. It also puts forward new study directions in view of the existing problems in studies of rhubarb and its anthraquinone, with the aim to provide reference for clinical treatment and scientific studies of effect of Rhei Radix et Rhizomaon autoimmune diseases.

Pathological Mechanism of PPs in Immune-related Enteropathy and Regulatory Effect of Traditional Chinese Medicine Polysaccharides / 中国实验方剂学杂志

Intestinal Peyer's patches （PPs） are local immune tissues of the intestine， which are considered to be the main induction site of the intestinal mucosal immune response， and closely related to immune-related refractory enteropathies， such as ulcerative colitis and Crohn's disease. In recent years， more and more scholars have tried to find a new breakthrough for treating refractory enteropathies with a limited efficacy of clinical interventions through in-depth study of the relationship between PPs and enteropathy. Traditional Chinese medicine （TCM） polysaccharides are considered to be a key component for immune regulation with TCM. Modern studies show that TCM polysaccharides have a significant positive intervention effect on the structure and function of PPs， with good development prospects. Based on this， this paper focuses on PPs and intestinal-related diseases， and systematically introduces the physiological structure of PPs and their drug delivery mechanism， and summarizes the interactions of PPs with effect on immune-related enteropathies， analyze of current studies and prospects of effect of TCM polysaccharides in intervening intestinal disease and its dysfunction by regulating PPs， with the aim to provide new strategies for basic studies and clinical treatment of immune-related refractory enteropathies from the perspective of PPs， and new ideas for basic studies and clinical studies on effect of TCM polysaccharides in intervening enteropathies.

Research progress on anti-tumor effects and mechanisms of triptolide and its combined application / 中国中药杂志

Tumors are major chronic diseases and seriously threaten human health all over the world. How to effectively control and cure tumors is one of the most pivotal problems in the medical field. At present,surgery,radiotherapy and chemotherapy are still the main treatment methods. However,the side effects of radiotherapy and chemotherapy cannot be underestimated. Therefore,it is of great practical significance to find new anti-cancer drugs with low toxicity,high efficiency and targeting to cancer cells. With the increasing incidence of tumor,the anti-tumor effect of traditional Chinese medicine has increasingly become a research hotspot. Triptolide,which is a natural diterpenoid active ingredient derived from of Tripterygium wilfordii,as one of the highly active components,has anti-inflammatory,immunosuppressive,anti-tumor and other multiple effects. A large number of studies have confirmed that it has good anti-tumor activity against various tumors in vivo and in vitro. It can play an anti-tumor role by inhibiting the proliferation of cancer cells,inducing apoptosis of cancer cells,inducing autophagy of cancer cells,blocking the cell cycle,inhibiting the migration,invasion and metastasis of cancer cells,reversing multidrug resistance,mediating tumor immunity and inhibiting angiogenesis. On the basis of literatures,this paper reviews the anti-tumor effect and mechanism of triptolide,and analyzes the current situation of triptolide combined with other chemotherapy drugs,in order to promote deep research and better clinical application about triptolide.
