OBJECTIVE:To study anti-inflammatory,analgesic and anti-fatigue effects of polysaccharides from Acanthopanan trifoliatus (ATMP) in rats and mice. METHODS:In hot plate experiment,150 mice were randomly divided into normal control group (constant volume of normal saline),aspirin group [200 mg/(kg·d)],and ATMP high-dose,medium-dose and low-dose groups [400,200,100 mg(gross polysaccharide)/(kg·d)];the threshold of pain was determined,and analgesic effect of ATMP was investigated. 150 mice were included in exhaustive swimming test and then randomly divided into normal control group(con-stant volume of normal saline),Chongcao yangshen jijing group [400 mg/(kg·d)by total saponins],and ATMP high-dose,medi-um-dose and low-dose groups [200,100,50 mg(gross polysaccharide)/(kg·d)];the body weight and exhaustive swimming time of mice were determined,and biochemical process was used to determine the contents of hepatic glycogen and muscle glycogen, and serum levels of BUN,LDH and CK in mice. The anti-fatigue effect of ATMP was investigated. In carrageenan-induced paw swelling experiment,40 rats were divided into normal control group (constant volume of normal saline),dexamethasone acetate group [5 mg/(kg·d)],ATMP high-dose,medium-dose and low-dose groups [100,50,25 mg(gross polysaccharide)/(kg·d)];the degree of paw swelling was recorded,and anti-inflammatory of ATMP was investigated. RESULTS:Compared with normal control group,the threshold of pain in mice were increased in ATMP 400,200,100 mg(gross polysaccharide)/(kg·d)groups;the exhaus-tive swimming time of mice were prolonged significantly,and the contents of hepatic glycogen in mice were increased significant-ly,while serum contents of CK decreased in ATMP 200,100 mg(gross polysaccharide)/(kg·d)groups;the content of muscle gly-cogen in mice was increased significantly in ATMP 200 mg (gross polysaccharide)/(kg·d) group,while serum contents of BUN and LDH were decreased;the degree of paw swelling in rats was decreased in ATMP 100,50,25 mg(gross polysaccharide)/(kg·d) groups,with statistical significance (P<0.01 or P<0.05). There was no significant difference in body weight of mice before and after medication. CONCLUSIONS:ATMP has significant analgesic and anti-fatigue effects on mice and anti-inflammatory effect on rats.

Research on standardization of traditional Chinese medicine(TCM) is playing an important role in constructing of modernized TCM.But it is difficult to set down a diagnosis and treatment standardization of TCM and it will cost long term and arduous work.Based on clinic and scientific research in recent years,this article focuses on the standardization research of diagnosis and treatment of AIDS with TCM to discuss the content,method and some pivotal questions.
