Objective. The present study is to investigate the analgesic roles of L-THP in rats with bone cancer pain caused by tumor cell implantation (TCI).Methods. Thermal hyperalgesia and mechanical allodynia were measured at different time points before and after operation. L-THP (20, 40, and 60 mg/kg) were administrated intragastrically at early phase of postoperation (before pain appearance) and later phase of postoperation (after pain appearance), respectively. The concentrations of TNF-α, IL-1β, and IL-18 in spinal cord were measured by enzyme-linked immunosorbent assay. Western blot was used to test the activation of astrocytes and microglial cells in spinal cord after TCI treatment.Results. TCI treatment induced significant thermal hyperalgesia and mechanical allodynia. Administration of L-THP at high doses significantly prevented and/or reversed bone cancer-related pain behaviors. Besides, TCI-induced activation of microglial cells and the increased levels of TNF-αand IL-18 were inhibited by L-THP administration. However, L-THP failed to affect TCI-induced astrocytes activation and IL-1βincrease.Conclusion. This study suggests the possible clinical utility of L-THP in the treatment of bone cancer pain. The analgesic effects of L-THP on bone cancer pain maybe underlying the inhibition of microglial cells activation and proinflammatory cytokines increase.

Bone cancer pain (BCP) is a severe type of hyperpathic pain occurring with primary bone tumors or advanced cancers which metastasize to bones. BCP can detrimentally reduce quality of life and presents a challenge to modern medicine. Studies have shown that exogenous H2S may act as a neuroprotectant to protect against some diseases in central nervous system. The preset study aimed to investigate the antinociceptive effect of H2S in BCP. We first measured the changes of serum H2S in patients with BCP and analyzed the relationship between them, then investigated the effect of H2S preconditioning on BCP, and explored the mechanism in rat model. Our results revealed that serum H2S level was negatively correlated with pain scores. In the rat model of BCP, preconditioning with H2S significantly reduced BCP, demonstrated by the decrease of thermal hyperalgesia and mechanical allodynia. The mechanism of H2S preconditioning may involve microglia deactivation and inflammation inhibition in the spinal cord, in which the proliferator-activated receptor gamma/p38/Jun N-terminal kinase pathway is activated. Impact statement Bone cancer pain (BCP) significantly decreases the life quality of patients or their life expectancy and causes a severe health burden to the society. However, as the exact mechanism of BCP is still poorly understood, no effective treatment has been developed yet. There are some pain medicines now, but they have some inevitable side effects. Additional therapeutic strategies are urgently needed. First, we revealed that preconditioning with H2S significantly reduced BCP, demonstrated by the decrease of thermal hyperalgesia and mechanical allodynia. Second, the mechanism of H2S preconditioning was elucidated. It may involve microglia deactivation and inflammation inhibition in the spinal cord, in which the proliferator-activated receptor gamma/p38/Jun N-terminal kinase pathway is activated. This novel finding may significantly help us to understand the difference between the roles of endogenous H2S and exogenous H2S in the development of BCP and present us a new strategy of pain management.
