[Objective]To explore the alleviating effect of Yunpi Yishen Tongdu Decoction on spinal lesion and immune inflammation of ankylosing spondylitis(AS)model mice,and to provide a scientific basis for its clinical application.[Methods]A total of 42 female BALB/c mice were randomly divided into blank group,model group,western medicine group,low,medium and high dose Yunpi Yishen Tongdu Decoction groups.Except for blank group,the remaining 5 groups were injected with proteoglycans in the abdominal cavity to construct AS model.After modeling,the mice in blank group and model group were given 0.9％sodium chloride solution,the mice in western medicine group were given 3.57 mg·mL-1 celecoxib solution,and the mice in the low,medium,and high dose Yunpi Yishen Tongdu Decoction were given 0.9,1.8 and 3.6 mg·mL-1 of Yunpi Yishen Tongdu Decoction for 4 weeks,respectively.After gavage,the behavioral changes,serum inflammation cytokines,spinal lesions,and expression of receptor activator of nuclear factor-κB ligand(RANKL),receptor activator of nuclear factor-κB(RANK),and osteoclastogenesis inhibitory factor(OPG)in the spine were measured.[Results]Compared with blank group,model group had significantly increased total time in tail immobility,serum interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)level,spinal pathological score,RANKL and RANK expression(P＜0.01,P＜0.05),while the vertebral bone mineral density and OPG expression of the spine were significantly decreased(P＜0.01).After treatment with the Yunpi Yishen Tongdu Decoction,the latency time in tail immobility in AS mice was significantly reduced,along with decreased serum levels of IL-6 and TNF-α and a notable reduction in spinal pathological scores(P＜0.01,P＜0.05).Additionally,the treatment downregulated RANKL and RANK expression,upregulated OPG expression(P＜0.01,P＜0.05).[Conclusion]Yunpi Yishen Tongdu Decoction alleviates the bone destruction of AS by affecting the RANKL/RANK/OPG pathway.

Purpose:To investigate the telomerase activity in human digestive tract cancer and its significance and evaluate usefulness of the TRAP ELISA method .Methods:Telomerase activity was examined in 112 tumor specimens, including the following cancers: esophageal(12), gastric(36), hepatic(15), pancreatic (11), colorectal(38) and paracancerous tissues(94) by TRAP ELISA method.Results:The telomerase activity in tumor tissues was significantly higher than in paracancerous and normal tissues ( P
