Background: Aromatase inhibitors (AIs) are recommended as the preferred therapy for postmenopausal women with hormone receptor-positive (HR+) breast cancer. As a result, aromatase inhibitor-associated musculoskeletal symptom (AIMSS) have become a major problem leading to therapy discontinuation and decreased quality of life in patients receiving adjuvant AIs treatment. Multiple therapies have been attempted, but have yielded limited clinical results. This study will be performed to determine whether acupoint thread embedding (ATE) combined with Wenshen Bugu Decoction can effectively treat AIMSS, so as to improve the AIs medication compliance of postmenopausal breast cancer patients. Methods: This study will utilize a randomized, 2 parallel groups controlled trial design. A total of 128 eligible postmenopausal breast cancer women with AIMSS will be randomized to receive a 12-week treatment with Wenshen Bugu Decoction alone (control group) or in combination with ATE (treatment group) in a 1:1 ratio. The primary outcome will be the 12 week Brief Pain Inventory Worst Pain (BPI-WP) score. The secondary outcome measures will include response rate, Brief Pain Inventory-Short Form (BFI-SF), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Functional Assessment of Cancer Therapy-Endocrine Symptom (FACT-ES), Functional Assessment of Cancer Therapy-Breast (FACT-B), bone marrow density (BMD), blood markers of bone metabolite, Morisky medication adherence scale-8 (MMAS-8), credibility and expectancy, and survival outcomes. Discussion: This trial may provide clinical evidence that ATE combined with Wenshen Bugu Decoction can be beneficial for treating AIMSS among postmenopausal breast cancer survivors. Our findings will be helpful to enhance the quality of life and reduce the occurrence of AIs withdrawal. more...

Desloratadine, a potent antagonist for human histamine H1 receptor, has been revealed to exhibit antihistaminic activity and anti-inflammatory activity. However, it is not yet known whether desloratadine has any effect on the biological behaviors of tumor cells. In this study, we aimed to investigate the effects of desloratadine on cell growth and invasion in bladder cancer EJ and SW780 cells in vitro . We observed that desloratadine inhibited cell viability of EJ and SW780 cells in a dose- and time-dependent manner. Desloratadine treatment was also revealed to suppress colony-formation ability and induce cell cycle arrest at G1 phase in EJ cells. Desloratadine promoted cell apoptosis via modulating the expression of Bcl-2, Bax, cleaved caspase 3, and cleaved caspase 9 in EJ and SW780 cells. Western blot resulted showed that desloratadine also impaired the expression of autophagy-related proteins, such as Beclin 1, P62, and LC3I/II in EJ and SW780 cells; while autophagy inhibitor LY294002 reversed the effects of desloratadine on these proteins. Moreover, desloratadine remarkably attenuated cell migration and invasion. Furthermore, we illustrated that desloratadine downregulated the expression of N-cadherin, Vimentin, Snail1, and Snail2, while upregulated the expression of E-cadherin in EJ and SW780 cells in vitro . The level of interleukin 6 was reduced in desloratadine-treated cells, while upregulation of interleukin 6 significantly abolished the anticancer activity of desloratadine in cell invasion and Bcl-2, Bax, Beclin1, LC3-I/II, N-cadherin, and E-cadherin expression in EJ cells. Taken together, our data suggest a potential anticancer activity of desloratadine on cell growth and invasion for bladder cancer, which may be mediated by diminishing the epithelial-to-mesenchymal transition and interleukin 6. more...
