[Nanometer preparation of traditional Chinese medicine for rheumatoid arthritis]

Rheumatoid arthritis( RA) is a chronic autoimmune disease,which can occur at any age. Repeated severe attacks can cause joint deformities. Its pathogenesis is complex,and the pathophysiological process involves many different types of cells. At present,the pathogenesis of RA is still unclear,and the clinical medication mainly aims to alleviate inflammation and symptoms.DMARDs,non-steroidal anti-inflammatory drugs,adrenocortical hormones,biological agents and traditional Chinese medicine are all applied in clinic. Traditional Chinese medicine has a long history in the treatment of RA. In particular,traditional Chinese medicine compounds can treat RA through multiple target points. The combination of nanotechnology and anti-inflammatory traditional Chinese and western medicines has also attracted extensive attention. Nanotechnology can selectively deliver drugs to articular cavity by taking advantage of its small carrier size and biodegradable materials. It can reduce the size of drug delivered,and increase the accuracy,safety and effectiveness of drugs,and further improve the therapeutic efficacy of drugs on RA. In this paper,traditional Chinese and western medicines and their nano-preparations used in the treatment of RA were reviewed in the past five years. The researches of nano-preparation were discussed in terms of pharmacology category. This paper provided reference for the research and development of new-type nano-preparation with outstanding clinical efficacy.
