ObjectiveTo investigate the therapeutic effect of the water extract of Zanthoxylum bungeanum aqueous extract（ZBAE）on rheumatoid arthritis. MethodThe sixty SD rats were divided into normal group， model group ［complete Freund's adjuvant （CFA）， 10 mg·kg-1］， methotrexate（MTX） group （0.25 mg·kg-1）， low -， medium -， and high-dose ZBAE groups （90， 180， 360 mg·kg-1）. The rats in MTX group were given intraperitoneal injection for two weeks， three times a week， and the rats in ZBAE group were administrated for 14 days. The swelling of the ankle joint and body weight were observed， and arthritis scores were also performed. Computed tomography （CT）， hematoxylin-eosin （HE） staining and safranine-O and fast green staining were used to observe the effect of ZBAE on synovial hyperplasia and bone protection. Cell counting kit-8（CCK-8）method was used to detect the proliferation of the RA-FLSs cells treated with ZBAE. According to the results of CCK-8 experiment， the optimal concentration and time of administration were determined， blank group， low -， medium -， and high-dose ZBAE groups （0.08，0.10，0.12 g·L-1） were set up. The cell cycle distribution and apoptosis rate were analyzed by flow cytometry，the migration ability of RA-FLSs cells was examined by scratch test. Western blot was used to detect the effect of ZBAE on phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， cyclin-dependent kinase 2 （CDK2）， Cyclin A and phosphorylated PI3K， Akt （p-PI3K，p-Akt） protein expression in RA-FLSs cells. ResultCompared with the normal group，joint swelling index and arthritis score were increased in the model group （P<0.05），the bone of the ankle was seriously damaged， and there was obvious synovial hyperplasia. Compared with the model group， the ZBAE group could significantly reduce the joint swelling index （P<0.05）， inhibit synovial hyperplasia and cartilage destruction. In vitro study showed that compared with the blank group， ZBAE could inhibit the migration of RA-FLSs （P<0.05）， promoted cell apoptosis （P<0.05）， and acted on RA-FLSs cells in S phase to inhibit cell proliferation. Moreover， the result of Western blot showed that compared with the blank group， the expression of p-PI3K， p-Akt， CDK2 and Cyclin A proteins were significantly decreased in the high dose group of ZBAE （P<0.05）. ConclusionThese results suggest that ZBAE has a therapeutic effect on rheumatoid arthritis by inhibiting synovial hyperplasia， promoting synovial apoptosis and inhibiting its migration.

Substitutes for Endangered Animal Medicinal Materials： A Review / 中国实验方剂学杂志

Endangered animal medicine is an important part of traditional Chinese medicine， which is distinctive in the treatment of diseases. At present， the rare and endangered medicinal materials such as tiger bone， rhinoceros horn， pangolin， antelope horn， bear bile are listed as national key protected animals， so their clinical application is limited， the current solution is mainly based on the ideas and methods of similar pharmacological effects， close genetic relationships， artificial breeding， and artificial synthesis to find and develop alternatives for endangered animal medicinal materials. Although artificially cultured bear bile and musk， and artificially synthesized tiger bone， bezoar and musk can solve the shortage of endangered animal medicines to a certain extent， there are still some problems such as difficult breakthroughs in breeding technology and incomplete recognition in the substitute industry. According to this， based on summarizing the existing substitutes for endangered animal medicines， our group proposed the concept of homology， homogeneity and equivalent of substitutes， and constructed a new idea to develop and evaluate substitutes by combining frontier biotechnology with multi-omics detection， so as to provide some support for protecting rare and endangered animals and solving the shortage of endangered animal medicines.
