These findings help to indicate that TCM fumigation "Bone-healing Powder" reduces the degrees of postoperative pain and swelling, and effectively improves recovery of the neurological function of those patients with traumatic TLS fractures, proving its worth as a clinical method in treatment.
Bufalin is a natural anti-inflammatory small molecule. Given the close relationship between inflammation and cancer, many scholars have studied the effect of bufalin on cancer in vitro, but in vivo research is still lacking. A murine bone cancer model was used in this study. We conducted pain sensitive test on mice with bone cancer, by nocifensive behavior, mechanical allodynia, and thermal hyperalgesia. Serum levels of bone loss markers with bufalin treatment were measured by ELISA. Expressions of osteoprotegerin (OPG) and receptor activator of NF-κB ligand (RANKL) were analyzed in bufalin-treated mice by real-time PCR and Western blot. Cannabinoid 2 receptor (CB2) inverse agonist AM630 was administrated to mice with bone cancer together with bufalin. Bufalin relieved cancer-induced pain and bone destruction in the murine bone cancer model. Serum levels of bone loss markers after bufalin treatment were reduced. Bufalin upregulated OPG and downregulated RANKL. The CB2 receptor inverse agonist, AM630, reduced the pain relief of bufalin treatment in the mouse bone cancer model. This study demonstrates that bufalin relieves cancer-induced pain and bone destruction, which is mediated through the CB2 receptor.
Based on the analysis of various access control models, an E-business workflow management system based on UCON is proposed. In order to achieve the security of access control, the UCONABC model, the RBAC access control model and the reference monitor are put into the workflow management system. For each access request, according to subject properties, roles, object properties, operation, obligation, as well as condition, the access control system makes judgments whether it has access permission or not. Before access, in access, or after access, the access control system renews the properties of the subject and the object for enhancing the robustness of the system greatly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
